https://en.wikipedia.org/wiki/Synaptic%20gating | Synaptic gating is the ability of neural circuits to gate inputs by either suppressing or facilitating specific synaptic activity. Selective inhibition of certain synapses has been studied thoroughly (see Gate theory of pain), and recent studies have supported the existence of permissively gated synaptic transmission. In general, synaptic gating involves a mechanism of central control over neuronal output. It includes a sort of gatekeeper neuron, which has the ability to influence transmission of information to selected targets independently of the parts of the synapse upon which it exerts its action (see also neuromodulation).
Bistable neurons have the ability to oscillate between a hyperpolarized (down state) and a depolarized (up state) resting membrane potential without firing an action potential. These neurons can thus be referred to as up/down neurons. According to one model, this ability is linked to the presence of NMDA and AMPA glutamate receptors. External stimulation of the NMDA receptors is responsible for moving the neuron from the down state to the up state, while the stimulation of AMPA receptors allows the neuron to reach and surpass the threshold potential. Neurons that have this bistable ability have the potential to be gated because outside gatekeeper neurons can modulate the membrane potential of the gated neuron by selectively shifting them from the up state to the down state. Such mechanisms have been observed in the nucleus accumbens, with gatekeepers |
https://en.wikipedia.org/wiki/Lamin%20B2 | Lamin B2 is a protein that in humans is encoded by the LMNB2 gene. It is the second of two type B nuclear lamins, and it is associated with laminopathies.
Model organisms
Model organisms have been used in the study of Lamin B2 function. A conditional knockout mouse line, called Lmnb2tm1a(KOMP)Wtsi was generated as part of the International Knockout Mouse Consortium program — a high-throughput mutagenesis project to generate and distribute animal models of disease to interested scientists.
Male and female animals underwent a standardized phenotypic screen to determine the effects of deletion. Twenty four tests were carried out on mutant mice and four significant abnormalities were observed. No homozygous mutant embryos were identified during gestation, and therefore none survived until weaning. The remaining tests were carried out on heterozygous mutant adult mice. Male heterozygotes displayed increased circulating creatinine levels and an increased susceptibility to Salmonella infection.

https://en.wikipedia.org/wiki/Lamin%20B%20receptor | Lamin-B receptor is a protein, and in humans, it is encoded by the LBR gene.
Function
The protein encoded by this gene belongs to the ERG4/ERG24 family. It localizes to the inner membrane of the nuclear envelope and anchors the lamina and the heterochromatin to the membrane. It may mediate the interaction between chromatin and lamin B. Mutations of this gene has been associated with autosomal recessive HEM/Greenberg skeletal dysplasia. Alternative splicing occurs at this locus and two transcript variants encoding the same protein have been identified.
Clinical significance
There is evidence tying it to Greenberg dysplasia and Pelger-Huet anomaly.
Interactions
Lamin B receptor has been shown to interact with CBX3 and CBX5. LBR also interacts with long non-coding RNA XIST in mouse cells and potentially assist the spreading XIST across X chromosome in differentiating female embryonic stem cells, but it might be redundant for correct XCI in vivo.

https://en.wikipedia.org/wiki/LEM%20domain-containing%20protein%203 | LEM domain-containing protein 3 (LEMD3), also known as MAN1, is an integral protein in the inner nuclear membrane (INM) of the nuclear envelope. It is encoded by the LEMD3 gene and was first identified after it was isolated from the serum of a patient with a collagen vascular disease.
Structure
The protein is 82.3 kDa and has a 40 amino acid long LEM domain located at its amino-terminal region. In its carboxyl end it has a RNA recognition motif (RRM). The LEM domain is also common to two other integral proteins of the INM: lamina-associated polypeptide 2 (LAP2) and emerin.
The LEM segment enables LEMD3 to attach to the barrier-to-autointegration factor (BAF), and therefore, indirectly interact with the chromatin. LEMD3 also has several implications in regulating the cytokine family such as the transforming growth factor beta (TGF-β) and bone morphogenic protein (BMPs). The RRM domain in its carboxylic region attaches to the SMAD (protein) proteins, which is involved in mediating TGF-β cellular signalling. Consequently, LEMD3 indirectly regulates downstream genes.
LEMD3 seems to play an important role in regulating the expression of several fundamental genes.
LEMD3 and disease
LEMD3 has been associated with laminopathies as well as osteopoikilosis. Mutations in the LEMD3 gene have been linked to several genetic diseases such as osteopoikilosis, melorheostosis and Buschke-Ollendorff syndrome.

https://en.wikipedia.org/wiki/Chip%20timing | Transponder timing (also called chip timing or RFID timing) is a technique for measuring performance in sport events. A transponder working on a radio-frequency identification (RFID) basis is attached to the athlete and emits a unique code that is detected by radio receivers located at the strategic points in an event.
Prior to the use of this technology, races were either timed by hand (with operators pressing a stopwatch) or using video camera systems.
Transponder systems
Generically, there are two types of transponder timing systems; active and passive. An active transponder consists of a battery-powered transceiver, connected to the athlete, that emits its unique code when it is interrogated.
A passive transponder does not contain a power source inside the transponder. Instead, the transponder captures electromagnetic energy produced by a nearby exciter and utilizes that energy to emit a unique code.
In both systems, an antenna is placed at the start, finish, and in some cases, intermediate time points and is connected to a decoder. This decoder identifies the unique transponder code and calculates the exact time when the transponder passes a timing point. Some implementations of timing systems require the use of a mat on the ground at the timing points while other systems implement the timing points with vertically oriented portals.
History
RFID was first used in the late 1980s primarily for motor racing and became more widely adopted in athletic events in the m |
https://en.wikipedia.org/wiki/Protocadherin | Protocadherins (Pcdhs) are the largest mammalian subgroup of the cadherin superfamily of homophilic cell-adhesion proteins. They were discovered by Shintaro Suzuki's group, when they used PCR to find new members of the cadherin family. The PCR fragments that corresponded to protocadherins were found in vertebrate and invertebrate species. This prevalence in a wide range of species suggested that the fragments were part of an ancient cadherin and were thus termed "Protocadherins" as the "first cadherins". Of the approximately 70 Pcdh genes identified in mammalian genomes, over 50 are located in tightly linked gene clusters on the same chromosome. Until recently, it was assumed that this kind of organization can only be found in vertebrates, but Octopus bimaculoides has 168 genes of which nearly three-quarters are found in tandem clusters with the two largest clusters compromising 31 and 17 genes, respectively.
Classification
In mammals, two types of Pcdh genes have been defined: the non-clustered Pcdhs which are scattered throughout the genome; and the clustered Pcdhs organized in three gene clusters designated α, β, γ which in mouse genome comprises 14, 22 and 22, respectively, large variable exons arrayed in tandem. Each exon is transcribed from its owner promoter and encodes: the entire extracellular domain, a transmembrane domain, and a short and variable intracellular domain of the corresponding Pcdh protein which differs from the Cadherin intracellular domain due to |
https://en.wikipedia.org/wiki/THP-1%20cell%20line | THP-1 is a human monocytic cell line derived from an acute monocytic leukemia patient. It is used to test leukemia cell lines in immunocytochemical analysis of protein-protein interactions, and immunohistochemistry.
Characteristics
Although THP-1 cells are of the same lineage, mutations can cause differences as the progeny proliferates. In general, THP-1 cells exhibit a large, round, single-cell morphology. The cells were derived from the peripheral blood of a 1-year-old human male with acute monocytic leukemia. Some of their characteristics are:
Expression of Fc receptor and C3b receptors while lacking surface and cytoplasmic immunoglobulins.
Production of IL-1.
Positive detection of alpha-naphthyl butyrate esterase and lysozymes
Phagocytic physiology (both for latex beads and sensitized erythrocytes).
Restoration of the response of purified T lymphocytes to Con A.
Increased CO2 production on phagocytosis and differentiation into macrophage-like cells

https://en.wikipedia.org/wiki/Rabson%E2%80%93Mendenhall%20syndrome | Rabson–Mendenhall syndrome is a rare autosomal recessive disorder characterized by severe insulin resistance. The disorder is caused by mutations in the insulin receptor gene. Symptoms include growth abnormalities of the head, face and nails, along with the development of acanthosis nigricans. Treatment involves controlling blood glucose levels by using insulin and incorporating a strategically planned, controlled diet. Also, direct actions against other symptoms may be taken (e.g. surgery for facial abnormalities) This syndrome usually affects children and has a prognosis of 1–2 years.
Presentation
The symptoms of Rabson–Mendenhall syndrome vary from case to case. Major symptoms of Rabson–Mendenhall syndrome include abnormalities of the teeth and nails, such as dental dysplasia, and deformities of the head and face, which include a coarse prematurely-aged facial appearance with a prominent jaw. A skin abnormality known as acanthosis nigricans, which involves a discoloration (hyperpigmentation) and "velvety" thickening (hyperkeratosis) of the skin around skin fold regions of the neck, groin and under arms is also a common symptom. Symptoms will negatively impact the daily life of the patient, and will persist until treated.
Minor symptoms may include an enlargement of the genitalia and precocious puberty and a deficiency or absence of fat tissue. Because individuals with Rabson–Mendenhall syndrome fail to use insulin properly, they may experience abnormally high blood suga |
https://en.wikipedia.org/wiki/Prostacyclin%20synthase | Prostaglandin-I synthase () also known as prostaglandin I2 (prostacyclin) synthase (PTGIS) or CYP8A1 is an enzyme involved in prostanoid biosynthesis that in humans is encoded by the PTGIS gene. This enzyme belongs to the family of cytochrome P450 isomerases.
Function
This gene encodes a member of the cytochrome P450 superfamily of enzymes. The cytochrome P450 proteins are monooxygenases which catalyze many reactions involved in drug metabolism and synthesis of cholesterol, steroids and other lipids. However, this protein is considered a member of the cytochrome P450 superfamily on the basis of sequence similarity rather than functional similarity. This endoplasmic reticulum membrane protein catalyzes the conversion of prostaglandin H2 to prostacyclin (prostaglandin I2), a potent vasodilator and inhibitor of platelet aggregation. An imbalance of prostacyclin and its physiological antagonist thromboxane A2 contribute to the development of myocardial infarction, stroke, and atherosclerosis.
Unlike most P450 enzymes, PGIS does not require molecular oxygen (O2). Instead it uses its heme cofactor to catalyze the isomerization of prostaglandin H2 to prostacyclin. Prostaglandin H2 is produced by cyclooxygenase in the first committed step of prostaglandin biosynthesis.
Nomenclature
The systematic name of this enzyme class is (5Z,13E)-(15S)-9alpha,11alpha-epidioxy-15-hydroxyprosta-5,13-dienoate 6-isomerase. Other names in common use include prostacyclin synthase, prostacyclin |

https://en.wikipedia.org/wiki/Long-chain-fatty-acid%E2%80%94CoA%20ligase | The long chain fatty acyl-CoA ligase (or synthetase) is an enzyme () of the ligase family that activates the oxidation of complex fatty acids. Long chain fatty acyl-CoA synthetase catalyzes the formation of fatty acyl-CoA by a two-step process proceeding through an adenylated intermediate. The enzyme catalyzes the following reaction,
Fatty acid + CoA + ATP ⇌ Acyl-CoA + AMP + PPi
It is present in all organisms from bacteria to humans. It catalyzes the pre-step reaction for β-oxidation of fatty acids or can be incorporated in phospholipids.
Function
Long chain fatty acyl-CoA synthetase, LC-FACS, plays a role in the physiological regulation of various cellular functions via the production of long chain fatty acyl-CoA esters, which reportedly have affected protein transport, enzyme activation, protein acylation, cell signaling, and transcriptional regulation. The formation of fatty acyl-CoA is catalyzed in two steps: a stable intermediate of fatty acyl-AMP molecule and then the product is formed—fatty acid acyl-CoA molecule.
Fatty acyl CoA synthetase catalyzes the activation of a long fatty acid chain to a fatty acyl CoA, requiring the energy of 1 ATP to AMP and pyrophosphate. This step uses 2 "ATP equivalents" because pyrophosphate is cleaved into 2 molecules of inorganic phosphate, breaking a high-energy phosphate bond.

https://en.wikipedia.org/wiki/Neprilysin | Neprilysin (), also known as membrane metallo-endopeptidase (MME), neutral endopeptidase (NEP), cluster of differentiation 10 (CD10), and common acute lymphoblastic leukemia antigen (CALLA) is an enzyme that in humans is encoded by the MME gene. Neprilysin is a zinc-dependent metalloprotease that cleaves peptides at the amino side of hydrophobic residues and inactivates several peptide hormones including glucagon, enkephalins, substance P, neurotensin, oxytocin, and bradykinin. It also degrades the amyloid beta peptide whose abnormal folding and aggregation in neural tissue has been implicated as a cause of Alzheimer's disease. Synthesized as a membrane-bound protein, the neprilysin ectodomain is released into the extracellular domain after it has been transported from the Golgi apparatus to the cell surface.
Neprilysin is expressed in a wide variety of tissues and is particularly abundant in kidney. It is also a common acute lymphocytic leukemia antigen that is an important cell surface marker in the diagnosis of human acute lymphocytic leukemia (ALL). This protein is present on leukemic cells of pre-B phenotype, which represent 85% of cases of ALL.
Hematopoietic progenitors expressing CD10 are considered "common lymphoid progenitors", which means they can differentiate into T, B or natural killer cells. CD10 is of use in hematological diagnosis since it is expressed by early B, pro-B and pre-B lymphocytes, and by lymph node germinal centers. Hematologic diseases in which |

https://en.wikipedia.org/wiki/CREB-binding%20protein | CREB-binding protein, also known as CREBBP or CBP or KAT3A, (where CREB is cAMP response element-binding protein) is a coactivator encoded by the CREBBP gene in humans, located on chromosome 16p13.3. CBP has intrinsic acetyltransferase functions; it is able to add acetyl groups to both transcription factors as well as histone lysines, the latter of which has been shown to alter chromatin structure making genes more accessible for transcription. This relatively unique acetyltransferase activity is also seen in another transcription enzyme, EP300 (p300). Together, they are known as the p300-CBP coactivator family and are known to associate with more than 16,000 genes in humans; however, while these proteins share many structural features, emerging evidence suggests that these two co-activators may promote transcription of genes with different biological functions.
For example, CBP alone has been implicated in a wide variety of pathophysiologies including colorectal cancer as well as head and neck squamous cell carcinoma. In these diseases, association of CBP with β-catenin has been shown to promote cancer cell proliferation and disease aggressiveness, whereas p300/ β-catenin leads to cell differentiation and/ or apoptosis. CBP has also been shown to help modulate liver function via maintenance of energy homeostasis in response to changes in cell nutrition conditions by regulating the activity of transcription factors and genes responsible for lipogenesis and gluconeogenesis.

https://en.wikipedia.org/wiki/DiOC6 | DiOC6 (3,3′-dihexyloxacarbocyanine iodide) is a fluorescent dye used for the staining of a cell's endoplasmic reticulum, vesicle membranes and mitochondria. Binding to these structures occurs via the dye's hydrophilic groups. DiOC6 can be used to label living cells, however they are quickly damaged due to the dye's extreme phototoxicity, so cells stained with this dye can only be exposed to light for short periods of time. When exposed to blue light, the dye fluoresces green.

https://en.wikipedia.org/wiki/ZP3 | Zona pellucida sperm-binding protein 3, also known as zona pellucida glycoprotein 3 (Zp-3) or the sperm receptor, is a ZP module-containing protein that in humans is encoded by the ZP3 gene. ZP3 is the glycoprotein in the zona pellucida most important for inducting the acrosome reaction of sperm cells at the beginning of fertilization.
Function
The zona pellucida (ZP) is a specialized extracellular matrix that surrounds the oocyte and early embryo. It is composed of three or four glycoproteins (ZP1-4) with various functions during oogenesis, fertilization and preimplantation development. The protein encoded by this gene is a major structural component of the ZP and functions in primary binding and stimulation of the sperm acrosome reaction. The nascent protein contains a N-terminal signal peptide sequence, a conserved "ZP domain" module, a consensus furin cleavage site (CFCS), a polymerization-blocking external hydrophobic patch (EHP), and a C-terminal transmembrane domain. Cleavage at the CFCS separates the mature protein from the EHP, allowing it to incorporate into nascent ZP filaments. A variation in the last exon of this gene has previously served as the basis for an additional ZP3 locus; however, sequence and literature review reveals that there is only one full-length ZP3 locus in the human genome. Another locus encoding a bipartite transcript designated POMZP3 contains a duplication of the last four exons of ZP3, including the above described variation, and maps cl |
https://en.wikipedia.org/wiki/Lubrication%20theory | In fluid dynamics, lubrication theory describes the flow of fluids (liquids or gases) in a geometry in which one dimension is significantly smaller than the others. An example is the flow above air hockey tables, where the thickness of the air layer beneath the puck is much smaller than the dimensions of the puck itself.
Internal flows are those where the fluid is fully bounded. Internal flow lubrication theory has many industrial applications because of its role in the design of fluid bearings. Here a key goal of lubrication theory is to determine the pressure distribution in the fluid volume, and hence the forces on the bearing components. The working fluid in this case is often termed a lubricant.
Free film lubrication theory is concerned with the case in which one of the surfaces containing the fluid is a free surface. In that case, the position of the free surface is itself unknown, and one goal of lubrication theory is then to determine this. Examples include the flow of a viscous fluid over an inclined plane or over topography. Surface tension may be significant, or even dominant. Issues of wetting and dewetting then arise. For very thin films (thickness less than one micrometre), additional intermolecular forces, such as Van der Waals forces or disjoining forces, may become significant.
Theoretical basis
Mathematically, lubrication theory can be seen as exploiting the disparity between two length scales. The first is the characteristic film thickness, , and |
https://en.wikipedia.org/wiki/Tandem%20affinity%20purification | Tandem affinity purification (TAP) is an immunoprecipitation-based purification technique for studying protein–protein interactions. The goal is to extract from a cell only the protein of interest, in complex with any other proteins it interacted with. TAP uses two types of agarose beads that bind to the protein of interest and that can be separated from the cell lysate by centrifugation, without disturbing, denaturing or contaminating the involved complexes. To enable the protein of interest to bind to the beads, it is tagged with a designed piece, the TAP tag.
The original TAP method involves the fusion of the TAP tag to the C-terminus of the protein under study. The TAP tag consists of three components: a calmodulin binding peptide (CBP), TEV protease cleavage site, and two Protein A domains, which bind tightly to IgG (making a TAP tag a type of epitope tag).
Many other tag/bead/eluent combinations have been proposed since the TAP principle was first published.
Variant tags
This tag is also known as the C-terminal TAP tag because an N-terminal version is also available. However, the method to be described assumes the use of a C-terminal tag, although the principle behind the method is still the same.
History
TAP tagging was invented by a research team working in the European Molecular Biology Laboratory in the late 1990s (Rigaut et al., 1999, Puig et al.,2001) and proposed as a new tool for proteome exploration. It was used by the team to characterize several protei |
https://en.wikipedia.org/wiki/Absolute%20radio-frequency%20channel%20number | In GSM cellular networks, an absolute radio-frequency channel number (ARFCN) is a code that specifies a pair of physical radio carriers used for transmission and reception in a land mobile radio system, one for the uplink signal and one for the downlink signal. ARFCNs for GSM are defined in Specification 45.005 Section 2. There are also other variants of the ARFCN numbering scheme that are in use for other systems that are not GSM. One such example is the TETRA system that has 25 kHz channel spacing and uses different base frequencies for numbering.
Different frequencies (ARFCNs) are used for the frequency-based component of GSMs multiple access scheme (FDMA — frequency-division multiple access). Uplink/downlink channel pairs in GSM are identified by ARFCN. Together with the time-based component (TDMA — time-division multiple access) the physical channel is defined by selecting a certain ARFCN and a certain time slot. Note not to confuse this physical channel with the logical channels (e.g. BCCH — Broadcast Control Channel) that are time-multiplexed onto it under the rules of GSM Specification 05.03.

This table shows the common channel numbers and corresponding uplink and downlink frequencies associated with a particular ARFCN, as well as the way to calculate the frequency from the ARFCN number and vice versa.

https://en.wikipedia.org/wiki/The%20Sphinx%20%28British%20Columbia%29 | The Sphinx is a mountain in the southernmost Coast Mountains of British Columbia, Canada. It is southeast of Garibaldi Lake.
Climate
Based on the Köppen climate classification, The Sphinx is located in a marine west coast climate zone of western North America. Most weather fronts originate in the Pacific Ocean, and travel east toward the Coast Mountains where they are forced upward by the range (Orographic lift), causing them to drop their moisture in the form of rain or snowfall. As a result, the Coast Mountains experience high precipitation, especially during the winter months in the form of snowfall. Temperatures can drop below −20 °C with wind chill factors below −30 °C.

https://en.wikipedia.org/wiki/Thymidylate%20synthase | Thymidylate synthase (TS) () is an enzyme that catalyzes the conversion of deoxyuridine monophosphate (dUMP) to deoxythymidine monophosphate (dTMP). Thymidine is one of the nucleotides in DNA. With inhibition of TS, an imbalance of deoxynucleotides and increased levels of dUMP arise. Both cause DNA damage.
Function
The following reaction is catalyzed by thymidylate synthase:
5,10-methylenetetrahydrofolate + dUMP dihydrofolate + dTMP
By means of reductive methylation, deoxyuridine monophosphate (dUMP) and N5,N10-methylene tetrahydrofolate are together used to form dTMP, yielding dihydrofolate as a secondary product.
This provides the sole de novo pathway for production of dTMP and is the only enzyme in folate metabolism in which the 5,10-methylenetetrahydrofolate is oxidised during one-carbon transfer. The enzyme is essential for regulating the balanced supply of the 4 DNA precursors in normal DNA replication: defects in the enzyme activity affecting the regulation process cause various biological and genetic abnormalities, such as thymineless death. The enzyme is an important target for certain chemotherapeutic drugs. Thymidylate synthase is an enzyme of about 30 to 35 kDa in most species except in protozoan and plants where it exists as a bifunctional enzyme that includes a dihydrofolate reductase domain. A cysteine residue is involved in the catalytic mechanism (it covalently binds the 5,6-dihydro-dUMP intermediate). The sequence around the active site of this enzy |
https://en.wikipedia.org/wiki/XRCC1 | DNA repair protein XRCC1, also known as X-ray repair cross-complementing protein 1, is a protein that in humans is encoded by the XRCC1 gene. XRCC1 is involved in DNA repair, where it complexes with DNA ligase III.
Function
XRCC1 is involved in the efficient repair of DNA single-strand breaks formed by exposure to ionizing radiation and alkylating agents. This protein interacts with DNA ligase III, polymerase beta and poly (ADP-ribose) polymerase to participate in the base excision repair pathway. It may play a role in DNA processing during meiogenesis, i.e. during the induction of meiosis and recombination in germ cells. A rare microsatellite polymorphism in this gene is associated with cancer in patients of varying radiosensitivity.
The XRCC1 protein does not have enzymatic activity, but acts as a scaffolding protein that interacts with multiple repair enzymes. The scaffolding allows these repair enzymes to then carry out their enzymatic steps in repairing DNA. XRCC1 is involved in single-strand break repair, base excision repair and nucleotide excision repair.
As reviewed by London, XRCC1 protein has three globular domains connected by two linker segments of ~150 and 120 residues. The XRCC1 N-terminal domain binds to DNA polymerase beta, the C-terminal BRCT domain interacts with DNA ligase III alpha and the central domain contains a poly(ADP-ribose) binding motif. This central domain allows recruitment of XRCC1 to polymeric ADP-ribose that forms on PARP1 after P |
https://en.wikipedia.org/wiki/DNA%20repair%20protein%20XRCC4 | DNA repair protein XRCC4 also known as X-ray repair cross-complementing protein 4 or XRCC4 is a protein that in humans is encoded by the XRCC4 gene. In addition to humans, the XRCC4 protein is also expressed in many other metazoans, fungi and in plants. The X-ray repair cross-complementing protein 4 is one of several core proteins involved in the non-homologous end joining (NHEJ) pathway to repair DNA double strand breaks (DSBs).
NHEJ requires two main components to achieve successful completion. The first component is the cooperative binding and phosphorylation of artemis by the catalytic subunit of the DNA-dependent protein kinase (DNA-PKcs). Artemis cleaves the ends of damaged DNA to prepare it for ligation. The second component involves the bridging of DNA to DNA Ligase IV (LigIV), by XRCC4, with the aid of Cernunnos-XLF. DNA-PKcs and XRCC4 are anchored to Ku70 / Ku80 heterodimer, which are bound to the DNA ends.
Since XRCC4 is the key protein that enables interaction of LigIV to damaged DNA and therefore ligation of the ends, mutations in the XRCC4 gene were found to cause embryonic lethality in mice and developmental inhibition and immunodeficiency in humans. Furthermore, certain mutations in the XRCC4 gene are associated with an increased risk of cancer.

https://en.wikipedia.org/wiki/Hartman%E2%80%93Grobman%20theorem | In mathematics, in the study of dynamical systems, the Hartman–Grobman theorem or linearisation theorem is a theorem about the local behaviour of dynamical systems in the neighbourhood of a hyperbolic equilibrium point. It asserts that linearisation—a natural simplification of the system—is effective in predicting qualitative patterns of behaviour. The theorem owes its name to Philip Hartman and David M. Grobman.
The theorem states that the behaviour of a dynamical system in a domain near a hyperbolic equilibrium point is qualitatively the same as the behaviour of its linearization near this equilibrium point, where hyperbolicity means that no eigenvalue of the linearization has real part equal to zero. Therefore, when dealing with such dynamical systems one can use the simpler linearization of the system to analyse its behaviour around equilibria.
Main theorem
Consider a system evolving in time with state that satisfies the differential equation for some smooth map . Now suppose the map has a hyperbolic equilibrium state : that is, and the Jacobian matrix of at state has no eigenvalue with real part equal to zero. Then there exists a neighbourhood of the equilibrium and a homeomorphism ,
such that and such that in the neighbourhood the flow of is topologically conjugate by the continuous map to the flow of its linearisation .
Even for infinitely differentiable maps , the homeomorphism need not to be smooth, nor even locally Lipschitz. However, it turns ou |
https://en.wikipedia.org/wiki/Babanki%20virus | Babanki virus (BBKV) is a member of the virus family Togaviridae of Class IV of the Baltimore classification system and the genus Alphavirus.
Genome and Structure
It has an unsegmented, positive sense, single-stranded RNA genome which is approximately 11.7kb long. In general, members of the Togaviridae have genomes which are able to be used directly as mRNA and the genome of BBKV can code for both structural and non-structural proteins. Currently, the genome of BBKV has only been partially sequenced. It has a spherical nucleocapsid which is approximately 40 nm in diameter and shows icosahedral symmetry of T=4. This nucleocapsid core is surrounded by a lipid envelope covered with glycoprotein spikes and virion particles are approximately 70 nm in diameter in total .
Disease
BBKV was first isolated in Babanki in Northwest Cameroon, Africa in 1969 and the disease is also known in Senegal and Madagascar . It is closely related to another Alphavirus, Sindbis virus and causes similar symptoms in humans like fever, arthralgia or joint pain and a rash. It is spread by an arthropod vector, typically mosquitoes of the genus Culex and in this way, may be described as an Arbovirus . Its normal host is birds .

https://en.wikipedia.org/wiki/Tetrahydrofolic%20acid | Tetrahydrofolic acid (THFA), or tetrahydrofolate, is a folic acid derivative.
Metabolism
Human synthesis
Tetrahydrofolic acid is produced from dihydrofolic acid by dihydrofolate reductase. This reaction is inhibited by methotrexate.
It is converted into 5,10-methylenetetrahydrofolate by serine hydroxymethyltransferase.
Bacterial synthesis
Many bacteria use dihydropteroate synthetase to produce dihydropteroate, a molecule without function in humans. This makes it a useful target for sulfonamide antibiotics, which compete with the PABA precursor.
Functions
Tetrahydrofolic acid is a cofactor in many reactions, especially in the synthesis (or anabolism) of amino acids and nucleic acids. In addition, it serves as a carrier molecule for single-carbon moieties, that is, groups containing one carbon atom e.g. methyl, methylene, methenyl, formyl, or formimino. When combined with one such single-carbon moiety as in 10-formyltetrahydrofolate, it acts as a donor of a group with one carbon atom. Tetrahydrofolate gets this extra carbon atom by sequestering formaldehyde produced in other processes. These single-carbon moieties are important in the formation of precursors for DNA synthesis. A shortage in tetrahydrofolic acid (FH4) can cause megaloblastic anemia.
Methotrexate acts on dihydrofolate reductase, like pyrimethamine or trimethoprim, as an inhibitor and thus reduces the amount of tetrahydrofolate made. This may result in megaloblastic anemia.

https://en.wikipedia.org/wiki/Dihydrofolic%20acid | Dihydrofolic acid (conjugate base dihydrofolate) (DHF) is a folic acid (vitamin B9) derivative which is converted to tetrahydrofolic acid by dihydrofolate reductase. Since tetrahydrofolate is needed to make both purines and pyrimidines, which are building blocks of DNA and RNA, dihydrofolate reductase is targeted by various drugs to prevent nucleic acid synthesis.

https://en.wikipedia.org/wiki/MycoBank | MycoBank is an online database, documenting new mycological names and combinations, eventually combined with descriptions and illustrations. It is run by the Westerdijk Fungal Biodiversity Institute in Utrecht.
Each novelty, after being screened by nomenclatural experts and found in accordance with the ICN (International Code of Nomenclature for algae, fungi, and plants), is allocated a unique MycoBank number before the new name has been validly published. This number then can be cited by the naming author in the publication where the new name is being introduced. Only then, this unique number becomes public in the database.
By doing so, this system can help solve the problem of knowing which names have been validly published and in which year.
MycoBank is linked to other important mycological databases such as Index Fungorum, Life Science Identifiers, Global Biodiversity Information Facility (GBIF) and other databases. MycoBank is one of three nomenclatural repositories recognized by the Nomenclature Committee for Fungi; the others are Index Fungorum and Fungal Names.

https://en.wikipedia.org/wiki/Gephyrin | Gephyrin is a protein that in humans is encoded by the GPHN gene.
This gene encodes a neuronal assembly protein that anchors inhibitory neurotransmitter receptors to the postsynaptic cytoskeleton via high affinity binding to a receptor subunit domain and tubulin dimers. In nonneuronal tissues, the encoded protein is also required for molybdenum cofactor biosynthesis. Mutations in this gene may be associated with the neurological condition hyperekplexia and also lead to molybdenum cofactor deficiency.
Gene
Numerous alternatively spliced transcript variants encoding different isoforms have been described; however, the full-length nature of all transcript variants is not currently known. The production of alternatively spliced variants is affected by noncoding regions within the gene. A ‘yin-yang’ noncoding sequence pair encompassing gephyrin has been identified. These sequences are opposites of each other - consisting of hundreds of divergent nucleotide states. Both of these patterns are uniquely human and evolved rapidly after splitting from their ancestral DNA pattern. The gephyrin yin and yang sequences are prevalent today in populations representing every major human ancestry.
Function
Gephyrin is a 93kDa multi-functional protein that is a component of the postsynaptic protein network of inhibitory synapses. It consists of 3 domains: N terminal G domain, C terminal E domain, and a large unstructured linker domain which connects the two. Although there are structure |
https://en.wikipedia.org/wiki/Alkylating%20antineoplastic%20agent | An alkylating antineoplastic agent is an alkylating agent used in cancer treatment that attaches an alkyl group (CnH2n+1) to DNA.
The alkyl group is attached to the guanine base of DNA, at the number 7 nitrogen atom of the purine ring.
Since cancer cells, in general, proliferate faster and with less error-correcting than healthy cells, cancer cells are more sensitive to DNA damage—such as being alkylated. Alkylating agents are used to treat several cancers. However, they are also toxic to normal cells (cytotoxic), particularly cells that divide frequently, such as those in the gastrointestinal tract, bone marrow, testicles and ovaries, which can cause loss of fertility. Most of the alkylating agents are also carcinogenic.
History
Before their use in chemotherapy, alkylating agents were better known for their use as sulfur mustard, ("mustard gas") and related chemical weapons in World War I. The nitrogen mustards were the first alkylating agents used medically, as well as the first modern cancer chemotherapies. Goodman, Gilman, and others began studying nitrogen mustards at Yale in 1942, and, following the sometimes dramatic but highly variable responses of experimental tumors in mice to treatment, these agents were first tested in humans late that year. Use of methyl bis (B-chloroethyl)emine hydrochloride (mechlorethamine, mustine) and tris (B-chloroethy) amine hydrochloride for Hodgkin's disease lymphosarcoma, leukemia, and other malignancies resulted in striking but te |

https://en.wikipedia.org/wiki/Robert%20Hayes%20%28serial%20killer%29 | Robert Tyrone Hayes (born March 12, 1982) is an American serial killer who has been convicted of three murders in the Daytona Beach, Florida, area between December 2005 and February 2006. DNA tests have also linked him to a fourth murder committed in March 2016. In addition, he remains the prime suspect in the murder of another woman in December 2007.
The first three murders that were committed in Daytona Beach, Florida, garnered high media attention, and before Hayes' identification, the perpetrator was nicknamed The Daytona Beach Killer. Investigators were not able to close in on a suspect in time. In December 2007, the murder of a woman in the same area caused a re-investigation to be brought forward, but again, Hayes remained elusive. In December 2016, DNA tests on a woman found murdered in Palm Beach County in March 2016 matched DNA found on the original three murdered women.
On September 15, 2019, authorities charged Hayes with one count of first-degree murder based upon DNA tests. On September 16, he was charged on three additional counts of first-degree murder. Additional testing after his arrest confirmed the link. Investigators had identified Hayes after identifying his family members through genetic genealogy, a tactic that has been used to solve numerous cold cases, most infamously the Golden State Killer. In February 2022, Hayes was convicted on three counts of first-degree murder and the following month was sentenced to three consecutive life sentences without |
https://en.wikipedia.org/wiki/Gracilicutes | Gracilicutes (Latin: gracilis, slender, and cutis, skin, referring to the cell wall) is a clade in bacterial phylogeny.
Traditionally gram staining results were most commonly used as a classification tool, consequently until the advent of molecular phylogeny, the Kingdom Monera (as the domains Bacteria and Archaea were known then) was divided into four phyla,
Gracilicutes (gram-negative, it is split in many groups, but some authors still use it in a narrower sense)
Firmacutes [sic] (gram-positive, subsequently corrected to Firmicutes, today it excludes the Actinomycetota)
Mollicutes (gram variable, later renamed Tenericutes and now Mycoplasmatota, e.g. Mycoplasma)
Mendosicutes (uneven gram stain, "methanogenic bacteria" now known as methanogens and classed as Archaea)
This classification system was abandoned in favour of the three-domain system based on molecular phylogeny started by C. Woese.
Using hand-drawn schematics rather than standard molecular phylogenetic analysis, Gracilicutes was revived in 2006 by Cavalier-Smith as an infrakindgom containing the phyla Spirochaetota, Sphingobacteria (FCB), Planctobacteria (PVC), and Proteobacteria. It is a gram-negative clade that branched off from other bacteria just before the evolutionary loss of the outer membrane or capsule, and just after the evolution of flagella. Most notably, this author assumed an unconventional tree of life placing Chloroflexota near the origin of life and Archaea as a close relative of Actinomyce |
https://en.wikipedia.org/wiki/Unfolded%20protein%20response | The unfolded protein response (UPR) is a cellular stress response related to the endoplasmic reticulum (ER) stress. It has been found to be conserved between mammalian species, as well as yeast and worm organisms.
The UPR is activated in response to an accumulation of unfolded or misfolded proteins in the lumen of the endoplasmic reticulum. In this scenario, the UPR has three aims: initially to restore normal function of the cell by halting protein translation, degrading misfolded proteins, and activating the signalling pathways that lead to increasing the production of molecular chaperones involved in protein folding. If these objectives are not achieved within a certain time span or the disruption is prolonged, the UPR aims towards apoptosis.
Sustained overactivation of the UPR has been implicated in prion diseases as well as several other neurodegenerative diseases, and inhibiting the UPR could become a treatment for those diseases. Diseases amenable to UPR inhibition include Creutzfeldt–Jakob disease, Alzheimer's disease, Parkinson's disease, and Huntington's disease.

https://en.wikipedia.org/wiki/Ribosomal%20s6%20kinase | In molecular biology, ribosomal s6 kinase (rsk) is a family of protein kinases involved in signal transduction. There are two subfamilies of rsk, p90rsk, also known as MAPK-activated protein kinase-1 (MAPKAP-K1), and p70rsk, also known as S6-H1 Kinase or simply S6 Kinase. There are three variants of p90rsk in humans, rsk 1-3. Rsks are serine/threonine kinases and are activated by the MAPK/ERK pathway. There are two known mammalian homologues of S6 Kinase: S6K1 and S6K2.
Substrates
Both p90 and p70 Rsk phosphorylate ribosomal protein s6, part of the translational machinery, but several other substrates have been identified, including other ribosomal proteins. Cytosolic substrates of p90rsk include protein phosphatase 1; glycogen synthase kinase 3 (GSK3); L1 CAM, a neural cell adhesion molecule; Son of Sevenless, the Ras exchange factor; and Myt1, an inhibitor of cdc2.
RSK phosphorylation of SOS1 (Son of Sevenless) at Serines 1134 and 1161 creates 14-3-3 docking site. This interaction of phospho SOS1 and 14-3-3 negatively regulates Ras-MAPK pathway.
p90rsk also regulates transcription factors including cAMP response element-binding protein (CREB); estrogen receptor-α (ERα); IκBα/NF-κB; and c-Fos.
Genomics
p90 Rsk-1 is located at 1p.
p90 Rsk-2 is located at Xp22.2 and contains 22 exons. Mutations in this gene have been associated with Coffin–Lowry syndrome, a disease characterised by severe psychomotor retardation and other developmental abnormalities.

It was colored by cartoonist Lark Pien, who received the 2007 Harvey Award for Best Colorist for her work on the book.
Synopsis
The story of American Born Chinese consists of three seemingly separate tales, which are tied together at the end of the book.
The first storyline is Yang's contemporary rendition of the Chinese story of a Kung Fu practicing Monkey King of Flower-Fruit Mountain, The Monkey King, a character from the classic 16th century Chinese novel Journey to the West. Yang replaces the Buddha from the original story with a Christian influenced deity Tze-Yo-Tzuh. Throughout the story, The Monkey King is unhappy with himself as a monkey and continually tries to become another version of himself. The Monkey King grows larger, taking a more human form.

(In the confined version of the problem, the logarithmic potential is modified.)
Interpretations
In the point-vortex gas interpretation, the particles represent either point vortices in a two-dimensional fluid, or parallel line vortices in a three-dimensional fluid. The constant ki is the circulation of the fluid around the ith vortex. The Hamiltonian H is the interaction term of the fluid's integrated kinetic energy; it may be either positive or negative. The equations of motion simply reflect the drift of each vortex's position in the velocity field of the other vortices.
In the guiding-center plasma interpretation, the particles represent long filaments of charge parallel to some external magnetic field. The constant ki is the linear charge density of the ith filament. The Hamiltonian H is just the two-dimensional Coulomb potential between lines. The equations of motion reflect the guiding center drift of the charge filaments, hence the name.

It is a derivative of the Once Upon a Time in China film series, and unlike other imitations, it can be considered a spin-off or parody to some extent. It was released after the first three films in the Once Upon a Time in China franchise. The film starred Jet Li as Chinese martial arts master and folk hero of Cantonese ethnicity, Wong Fei-hung and the action choreography was done by Yuen Woo-ping. However Last Hero in China differs greatly in tone from the Once Upon a Time in China films as it contains stronger elements of violence and broader, more slapstick, comedy. The film contains some Easter eggs, such as a Lifebuoy poster in the 19th century, a staff of the Monkey King, a guandao and Ne Zha's Universe Ring.

Ellis Gene Smith was born in Ogden, Utah to a traditional Mormon family. He studied at a variety of institutions of higher education in the U.S.: Adelphi College, Hobart College, University of Utah, and the University of Washington in Seattle.
At Seattle, he was able to study with Dezhung Rinpoche and members of the Sakya Phuntso Phodrang family who had been brought to Seattle under the auspices of the Rockefeller Foundation grant to the Far Eastern and Russian Institute. He studied Tibetan culture and Buddhism with Dezhung Rinpoche from 1960 to 1964 and spent the summer of 1962 traveling to the other Rockefeller centers in Europe to meet with other Tibetan savants.
In 1964 he completed his Ph.D. qualifying exams and traveled to Leiden for advanced studies in Sanskrit and Pali. In 1965 he went to India under a Foreign Area Fellowship Program (Ford Foundation) grant to study with living exponents of all of the Tibetan Buddhist and Bönpo traditions.
He began his studies with Geshe Lobsang Lungtok (Ganden Changtse), Drukpa Thoosay Rinpoche and Khenpo Noryang, and Dilgo Khyentse Rinpoche. He decided to remain in India to continue serious studies of Tibetan Buddhism and culture. He traveled extensively in the borderlands of India and Nepal. In 1968 he joined the Library of Congress New Delhi Field Office. He then began a project which wa |
https://en.wikipedia.org/wiki/Bacterial%20transcription | Bacterial transcription is the process in which a segment of bacterial DNA is copied into a newly synthesized strand of messenger RNA (mRNA) with use of the enzyme RNA polymerase.
The process occurs in three main steps: initiation, elongation, and termination; and the end result is a strand of mRNA that is complementary to a single strand of DNA. Generally, the transcribed region accounts for more than one gene. In fact, many prokaryotic genes occur in operons, which are a series of genes that work together to code for the same protein or gene product and are controlled by a single promoter. Bacterial RNA polymerase is made up of four subunits and when a fifth subunit attaches, called the σ-factor, the polymerase can recognize specific binding sequences in the DNA, called promoters. The binding of the σ-factor to the promoter is the first step in initiation. Once the σ-factor releases from the polymerase, elongation proceeds. The polymerase continues down the double stranded DNA, unwinding it and synthesizing the new mRNA strand until it reaches a termination site. There are two termination mechanisms that are discussed in further detail below. Termination is required at specific sites for proper gene expression to occur. Gene expression determines how much gene product, such as protein, is made by the gene. Transcription is carried out by RNA polymerase but its specificity is controlled by sequence-specific DNA binding proteins called transcription factors. Transcription fa |
https://en.wikipedia.org/wiki/Eukaryotic%20transcription | Eukaryotic transcription is the elaborate process that eukaryotic cells use to copy genetic information stored in DNA into units of transportable complementary RNA replica. Gene transcription occurs in both eukaryotic and prokaryotic cells. Unlike prokaryotic RNA polymerase that initiates the transcription of all different types of RNA, RNA polymerase in eukaryotes (including humans) comes in three variations, each translating a different type of gene. A eukaryotic cell has a nucleus that separates the processes of transcription and translation. Eukaryotic transcription occurs within the nucleus where DNA is packaged into nucleosomes and higher order chromatin structures. The complexity of the eukaryotic genome necessitates a great variety and complexity of gene expression control.
Eukaryotic transcription proceeds in three sequential stages: initiation, elongation, and termination.
The RNAs transcribed serve diverse functions. For example, structural components of the ribosome are transcribed by RNA polymerase I. Protein coding genes are transcribed by RNA polymerase II into messenger RNAs (mRNAs) that carry the information from DNA to the site of protein synthesis. More abundantly made are the so-called non-coding RNAs account for the large majority of the transcriptional output of a cell. These non-coding RNAs perform a variety of important cellular functions.
RNA polymerase
Eukaryotes have three nuclear RNA polymerases, each with distinct roles and properties.

https://en.wikipedia.org/wiki/Transcription%20factor%20Jun | Transcription factor Jun is a protein that in humans is encoded by the JUN gene. c-Jun, in combination with protein c-Fos, forms the AP-1 early response transcription factor. It was first identified as the Fos-binding protein p39 and only later rediscovered as the product of the JUN gene. c-jun was the first oncogenic transcription factor discovered. The proto-oncogene c-Jun is the cellular homolog of the viral oncoprotein v-jun (). The viral homolog v-jun was discovered in avian sarcoma virus 17 and was named for ju-nana, the Japanese word for 17. The human JUN encodes a protein that is highly similar to the viral protein, which interacts directly with specific target DNA sequences to regulate gene expression. This gene is intronless and is mapped to 1p32-p31, a chromosomal region involved in both translocations and deletions in human malignancies.
Function
Regulation
Both Jun and its dimerization partners in AP-1 formation are subject to regulation by diverse extracellular stimuli, which include peptide growth factors, pro-inflammatory cytokines, oxidative and other forms of cellular stress, and UV irradiation. For example, UV irradiation is a potent inducer for elevated c-jun expression.
c-jun transcription is autoregulated by its own product, Jun. The binding of Jun (AP-1) to a high-affinity AP-1 binding site in the jun promoter region induces jun transcription. This positive autoregulation by stimulating its own transcription may be a mechanism for prolonging the si |
https://en.wikipedia.org/wiki/AP-1%20transcription%20factor | Activator protein 1 (AP-1) is a transcription factor that regulates gene expression in response to a variety of stimuli, including cytokines, growth factors, stress, and bacterial and viral infections. AP-1 controls a number of cellular processes including differentiation, proliferation, and apoptosis. The structure of AP-1 is a heterodimer composed of proteins belonging to the c-Fos, c-Jun, ATF and JDP families.
History
AP-1 was first discovered as a TPA-activated transcription factor that bound to a cis-regulatory element of the human metallothionein IIa (hMTIIa) promoter and SV40. The AP-1 binding site was identified as the 12-O-Tetradecanoylphorbol-13-acetate (TPA) response element (TRE) with the consensus sequence 5’-TGA G/C TCA-3’. The AP-1 subunit Jun was identified as a novel oncoprotein of avian sarcoma virus, and Fos-associated p39 protein was identified as the transcript of the cellular Jun gene. Fos was first isolated as the cellular homologue of two viral v-fos oncogenes, both of which induce osteosarcoma in mice and rats. Since its discovery, AP-1 has been found to be associated with numerous regulatory and physiological processes, and new relationships are still investigated.
Structure
AP-1 transcription factor is assembled through the dimerization of a characteristic bZIP domain (basic region leucine zipper) in the Fos and Jun subunits. A typical bZIP domain consists of a “leucine zipper” region, and a “basic region”. The leucine zipper is responsible fo |
https://en.wikipedia.org/wiki/Circular%20mean | In mathematics and statistics, a circular mean or angular mean is a mean designed for angles and similar cyclic quantities, such as times of day, and fractional parts of real numbers.
This is necessary since most of the usual means may not be appropriate on angle-like quantities. For example, the arithmetic mean of 0° and 360° is 180°, which is misleading because 360° equals 0° modulo a full cycle. As another example, the "average time" between 11 PM and 1 AM is either midnight or noon, depending on whether the two times are part of a single night or part of a single calendar day.
The circular mean is one of the simplest examples of directional statistics and of statistics of non-Euclidean spaces.
This computation produces a different result than the arithmetic mean, with the difference being greater when the angles are widely distributed. For example, the arithmetic mean of the three angles 0°, 0°, and 90° is (0° + 0° + 90°) / 3 = 30°, but the vector mean is arctan(1/2) = 26.565°. Moreover, with the arithmetic mean the circular variance is only defined ±180°.
Definition
Since the arithmetic mean is not always appropriate for angles, the following method can be used to obtain both a mean value and measure for the variance of the angles:
Convert all angles to corresponding points on the unit circle, e.g., to . That is, convert polar coordinates to Cartesian coordinates. Then compute the arithmetic mean of these points. The resulting point will lie within the unit disk but |

https://en.wikipedia.org/wiki/ITK%20%28gene%29 | Tyrosine-protein kinase ITK/TSK also known as interleukin-2-inducible T-cell kinase or simply ITK, is a protein that in humans is encoded by the ITK gene. ITK is a member of the TEC family of kinases and is highly expressed in T cells.
Function
This gene encodes an intracellular tyrosine kinase expressed in T-cells. The protein is thought to play a role in T-cell proliferation and differentiation. ITK is functionally important for the development and effector function of Th2 and Th17 cells.
Mice lacking ITK were shown to not be susceptible to asthma.
Structure
This protein contains the following domains, which are often found in intracellular kinases:

https://en.wikipedia.org/wiki/White%20torture | White torture, often referred to as white room torture, is a type of psychological torture technique aimed at complete sensory deprivation and isolation. A prisoner is held in a cell that deprives them of all senses and identity. It is particularly used in Iran; however, there is also evidence of its use by the Venezuelan and the United States intelligence services.
Methodology
Visually, the prisoner is deprived of all colour. Their cell is completely white: the walls, floor and ceiling, as well as their clothes and food. Neon tubes are positioned above the occupant in such a way that no shadows appear.
Auditorily, the cell is soundproof, and void of any sound, voices or social interaction. Guards stand in silence, wearing padded shoes to avoid making any noise. Prisoners cannot hear anything but themselves.
In terms of taste and smell, the prisoner is fed white food—classically, unseasoned rice—to deprive them of these senses. Further, all surfaces are smooth, robbing them of the variability of touch sensations.
Detainees are often held for months, or even years. The effects of white torture are well-documented in a number of testimonials. Typically, prisoners will become depersonalized by losing personal identity for extended periods of isolation. Other effects include hallucinations, or even psychotic breaks.

https://en.wikipedia.org/wiki/Mediator%20%28coactivator%29 | Mediator is a multiprotein complex that functions as a transcriptional coactivator in all eukaryotes. It was discovered in 1990 in the lab of Roger D. Kornberg, recipient of the 2006 Nobel Prize in Chemistry. Mediator complexes interact with transcription factors and RNA polymerase II. The main function of mediator complexes is to transmit signals from the transcription factors to the polymerase.
Mediator complexes are variable at the evolutionary, compositional and conformational levels. The first image shows only one "snapshot" of what a particular mediator complex might be composed of, but it certainly does not accurately depict the conformation of the complex in vivo. During evolution, mediator has become more complex. The yeast Saccharomyces cerevisiae (a simple eukaryote) is thought to have up to 21 subunits in the core mediator (exclusive of the CDK module), while mammals have up to 26.
Individual subunits can be absent or replaced by other subunits under different conditions. Also, there are many intrinsically disordered regions in mediator proteins, which may contribute to the conformational flexibility seen both with and without other bound proteins or protein complexes. A more realistic model of a mediator complex without the CDK module is shown in the second figure.
The mediator complex is required for the successful transcription by RNA polymerase II. Mediator has been shown to make contacts with the polymerase in the transcription preinitiation complex. A rec |
https://en.wikipedia.org/wiki/Carlyle%20Harmon | Frank Carlyle Harmon (January 17, 1905 – March 25, 1997) was an American former head of fabrics research for Johnson and Johnson. He is best known for his patent, held jointly with Billy Gene Harper of Dow Chemical, that made the possible the production of modern "superabsorbent" disposable diapers.
Background
Harmon was born in Sugar City, Idaho to Frank Milton Harmon and Sophia Jones. He spent most of his childhood in Santa Clara, California, and he was a lifelong Mormon. At age ten he took a job at a printing office for a man named Henry Roth. In October, 1923 he attended Stanford University, receiving a bachelor's degree in 1927, a master's degree in 1928, and a Ph.D. in 1930. He married the former Delta Arbon on March 22, 1929. After working for the Marathon Paper co. of Wausau, Wisconsin, for a time, Harmon was employed by the Chicopee division of Johnson and Johnson in 1947.
"Superabsorbent" disposable diapers
The disposable diaper, in its original form invented by Victor Mills of Procter & Gamble, required a core of thick rolls of paper in order to adequately contain fluid and guard against diaper rash. This made the diapers undesirably heavy and bulky. In 1966, Harmon and Harper each independently discovered that a small amount of a highly absorbent polymer could be more effectively used in place of rolls of paper in the diaper's core. The two men each filed substantively identical patents on the polymer at the same time.

https://en.wikipedia.org/wiki/Crystal%20Palace%20F.C.%20%281861%29 | Crystal Palace F.C. was an amateur football club formed in 1861 who contributed to the development of association football during its formative years. They were founder members of the Football Association in 1863, and competed in the first ever FA Cup competition in 1871–72.
The club disbanded around 1876, its last entry listing in the Football Annual appeared in the 1875 edition. However, the current professional Crystal Palace F.C. claims to be a continuation of the original club, although this has been disputed by football historians.
History
Formation
In 1854, Queen Victoria opened the new Crystal Palace Exhibition building in South London near to Sydenham Hill. The building had gained fame in 1851 when it housed the Great Exhibition in Hyde Park, London. The Crystal Palace Park, which surrounded the site of the exhibition building, officially opened in 1856, and incorporated various sports facilities including a cricket ground. The first Crystal Palace football club was formed here in 1861. Many of its original players were members of Crystal Palace Cricket Club founded in 1857.
Grounds
The club initially played in Crystal Palace Park using the cricket field. The first game recorded as being played at the Crystal Palace was on 5 April 1862 against Forest Football Club (who later became Wanderers F.C.). For the 1864–65 and 1865–66 seasons, the club moved and played on a field behind the Crooked Billet pub in Penge. In 1866–67 they were homeless, and only three games |
https://en.wikipedia.org/wiki/Solid%20fat%20index | Solid fat index (SFI) is a measure of the percentage of fat in crystalline (solid) phase to total fat (the remainder being in liquid phase) across a temperature gradient. The SFI of a fat is measured using a dilatometer that measures the expansion of a fat as it is heated; density measurements are taken at a series of standardized temperature check points. The resulting SFI/temperature curve is related to melting qualities and flavor. For example, butter has a sharp SFI curve, indicating that it melts quickly and that it releases flavor quickly.

https://en.wikipedia.org/wiki/Molecular%20pathology | Molecular pathology is an emerging discipline within pathology which is focused in the study and diagnosis of disease through the examination of molecules within organs, tissues or bodily fluids. Molecular pathology shares some aspects of practice with both anatomic pathology and clinical pathology, molecular biology, biochemistry, proteomics and genetics, and is sometimes considered a "crossover" discipline.
It is multi-disciplinary in nature and focuses mainly on the sub-microscopic aspects of disease. A key consideration is that more accurate diagnosis is possible when the diagnosis is based on both the morphologic changes in tissues (traditional anatomic pathology) and on molecular testing.
It is a scientific discipline that encompasses the development of molecular and genetic approaches to the diagnosis and classification of human diseases, the design and validation of predictive biomarkers for treatment response and disease progression, the susceptibility of individuals of different genetic constitution to develop disorders.
Molecular pathology is commonly used in diagnosis of cancer and infectious diseases. Techniques are numerous but include quantitative polymerase chain reaction (qPCR), multiplex PCR, DNA microarray, in situ hybridization, in situ RNA sequencing, DNA sequencing, antibody based immunofluorescence tissue assays, molecular profiling of pathogens, and analysis of bacterial genes for antimicrobial resistance.

https://en.wikipedia.org/wiki/Sieve%20C%2B%2B%20Parallel%20Programming%20System | The Sieve C++ Parallel Programming System is a C++ compiler and parallel runtime designed and released by Codeplay that aims to simplify the parallelization of code so that it may run efficiently on multi-processor or multi-core systems. It is an alternative to other well-known parallelisation methods such as OpenMP, the RapidMind Development Platform and Threading Building Blocks (TBB).
Introduction
Sieve is a C++ compiler that will take a section of serial code, which is annotated with sieve markers, and parallelize it automatically. The programmer wraps code they wish to parallelise inside a lexical scope, which is tagged as 'sieve'. Inside this scope, referred to commonly as a 'sieve block', certain rules apply :
All side-effects within the sieve block are delayed until the end of the scope.
Side-effects are defined to be any modifications to data declared outside the sieve block scope.
Only functions annotated with sieve or immediate can be called.
Delaying side-effects removes many small dependencies which would usually impede automatic parallelization. Reads and writes can be safely reordered by the compiler as to allow better use of various data movement mechanisms, such as Direct Memory Access(DMA). In addition, alias analysis and dataflow analysis can be simplified . The compiler can then split up code within the sieve block much easier, to exploit parallelism.

https://en.wikipedia.org/wiki/Aldolase%20B | Aldolase B also known as fructose-bisphosphate aldolase B or liver-type aldolase is one of three isoenzymes (A, B, and C) of the class I fructose 1,6-bisphosphate aldolase enzyme (EC 4.1.2.13), and plays a key role in both glycolysis and gluconeogenesis. The generic fructose 1,6-bisphosphate aldolase enzyme catalyzes the reversible cleavage of fructose 1,6-bisphosphate (FBP) into glyceraldehyde 3-phosphate and dihydroxyacetone phosphate (DHAP) as well as the reversible cleavage of fructose 1-phosphate (F1P) into glyceraldehyde and dihydroxyacetone phosphate. In mammals, aldolase B is preferentially expressed in the liver, while aldolase A is expressed in muscle and erythrocytes and aldolase C is expressed in the brain. Slight differences in isozyme structure result in different activities for the two substrate molecules: FBP and fructose 1-phosphate. Aldolase B exhibits no preference and thus catalyzes both reactions, while aldolases A and C prefer FBP.
In humans, aldolase B is encoded by the ALDOB gene located on chromosome 9. The gene is 14,500 base pairs long and contains 9 exons. Defects in this gene have been identified as the cause of hereditary fructose intolerance (HFI).
Mechanism
The generic fructose bisphosphate aldolase enzyme cleaves a 6-carbon fructose sugar into two 3-carbon products in a reverse aldol reaction. This reaction is typified by the formation of a Schiff base intermediate with a lysine residue (lysine 229) in the active site of the enzyme; |

Phospholipase A1 (EC 3.1.1.32; systematic name: phosphatidylcholine 1-acylhydrolase) encoded by the PLA1A gene is a phospholipase enzyme which removes the 1-acyl group:
phosphatidylcholine + H2O ⇌ 2-acylglycerophosphocholine + a carboxylate
It is an enzyme that resides in a class of enzymes called phospholipase that hydrolyze phospholipids into fatty acids. There are four classes, separated according to the type of reaction they catalyze. In particular, phospholipase A1 (PLA1) specifically catalyzes the cleavage at the sn-1 position of phospholipids, forming a fatty acid and a lysophospholipid.
Function
PLA1's are present in numerous species including humans, and have a variety of cellular functions that include regulation and facilitation of the production of lysophospholipid mediators, and acting as digestive enzymes. These enzymes are responsible for fast turnover rates of cellular phospholipids. In addition to this, the products of the reaction catalyzed by PLA1 which are a fatty acid and a lysophospholipid are important in various biological functions such as platelet aggregation and smooth muscle contraction. In addition, lysophospholipids can be found as surfactants in food techniques and cosmetics, and can be used in drug delivery. Since PLA1 is found in many species, it has been found that there are different classes of this one specific enzyme based on the organism being studied.

It is also known as monocyte chemotactic protein 5 (MCP-5) and, due to its similarity with the human chemokine MCP-1, sometimes it is called MCP-1-related chemokine. CCL12 specifically attracts eosinophils, monocytes and lymphocytes. This chemokine is found predominantly in lymph nodes and thymus under normal conditions, and its expression can be hugely induced in macrophages. It is thought to coordinate cell movements during early allergic reactions, and immune response to pathogens. The gene for CCL12 is found in a cluster of CC chemokines on mouse chromosome 11.

CCL9 has also been previously designated CCL10, although this name is no longer in use. It is secreted by follicle-associated epithelium (FAE) such as that found around Peyer's patches, and attracts dendritic cells that possess the cell surface molecule CD11b and the chemokine receptor CCR1. CCL9 can activate osteoclasts through its receptor CCR1 (the most abundant chemokine receptor found on osteoclasts) suggesting an important role for CCL9 in bone resorption. CCL9 is constitutively expressed in macrophages and myeloid cells. The gene for CCL9 is located on chromosome 11 in mice.
CCL9 is a chemokine involved in the process of signaling an antileukemic response and is a potential form of immunotherapy for chronic myelogenous leukemia (CML). CML is a type of cancer in which the bone marrow produces too many red blood cells. This is caused by chromosomal translocation, a mutation in which the abnormal gene BCR-ABL, is turned into a CML cell. CML starts off as a myeloproliferative for example in sickle cell anemia or extreme granulocytosis but if left untreated, it could transform into an acute form of leukemia. In order to treat CML, alpha and beta interferons (INFs) are used to regulate the process of bin |

https://en.wikipedia.org/wiki/Fecal%20sac | A fecal sac (also spelled faecal sac) is a mucous membrane, generally white or clear with a dark end, that surrounds the feces of some species of nestling birds. It allows parent birds to more easily remove fecal material from the nest. The nestling usually produces a fecal sac within seconds of being fed; if not, a waiting adult may prod around the youngster's cloaca to stimulate excretion. Young birds of some species adopt specific postures or engage in specific behaviors to signal that they are producing fecal sacs. For example, nestling curve-billed thrashers raise their posteriors in the air, while young cactus wrens shake their bodies. Other species deposit the sacs on the rim of the nest, where they are likely to be seen (and removed) by parent birds.
Not all species generate fecal sacs. They are most prevalent in passerines and their near relatives, which have altricial young that remain in the nest for longer periods. In some species, the fecal sacs of small nestlings are eaten by their parents. In other species, and when nestlings are older, sacs are typically taken some distance from the nest and discarded. Young birds generally stop producing fecal sacs shortly before they fledge.
Removal of fecal material helps to improve nest sanitation, which in turn helps to increase the likelihood that nestlings will remain healthy. It also helps to reduce the chance that predators will see it or smell it and thereby find the nest. Experiments on starling nests suggest th |

There are several ways to classify climates into similar regimes. Originally, climes were defined in Ancient Greece to describe the weather depending upon a location's latitude. Modern climate classification methods can be broadly divided into genetic methods, which focus on the causes of climate, and empiric methods, which focus on the effects of climate. Examples of genetic classification include methods based on the relative frequency of different air mass types or locations within synoptic weather disturbances. Examples of empiric classifications include climate zones defined by plant hardiness, evapotranspiration, or associations with certain biomes, as in the case of the Köppen climate classification. A common shortcoming of these classification schemes is that they produce distinct boundaries between the zones they define, rather than the gradual transition of climate properties more common in nature.

https://en.wikipedia.org/wiki/Sami%20Essid | Sami bin Khamis bin Salih Essid ()
a.k.a. Essid Sami Ben Khemais was the head of al-Qaeda's Italian cell until his arrest outside Milan in April 2001. He received a five-year sentence for trafficking in arms, explosives, and chemicals. Essid remains under embargo by the United Nations Security Council Committee 1267 as an affiliate of al-Qaeda, and by the US Treasury for his terrorist activity. Around 1 July 2007, fresh charges against Sami Essid were read in Italy, where he was still in custody.
According to the UN he was born on 10 February 1968 in Menzel Jemil, Bizerte Governorate, Tunisia.
He phoned a cell phone held by Saber Mohammed - believed to have been acting as a messenger for Mosa Zi Zemmori and Driss Elatellah.
Guantanamo connection
Following the United States Supreme Court ruling in Rasul v. Bush, the United States Department of Defense was forced to conduct reviews of the combatant status of the captives held in extrajudicial detention in its Guantanamo Bay detainment camps, in Cuba.
The allegations that Guantanamo counter-terror analysts offered to justify the detention of several of these captives assert that they had an association with Sami Essid, or the Sami Essid Network.

https://en.wikipedia.org/wiki/Observed%20information | In statistics, the observed information, or observed Fisher information, is the negative of the second derivative (the Hessian matrix) of the "log-likelihood" (the logarithm of the likelihood function). It is a sample-based version of the Fisher information.
Definition
Suppose we observe random variables , independent and identically distributed with density f(X; θ), where θ is a (possibly unknown) vector. Then the log-likelihood of the parameters given the data is
.
We define the observed information matrix at as
Since the inverse of the information matrix is the asymptotic covariance matrix of the corresponding maximum-likelihood estimator, the observed information is often evaluated at the maximum-likelihood estimate for the purpose of significance testing or confidence-interval construction. The invariance property of maximum-likelihood estimators allows the observed information matrix to be evaluated before being inverted.
Alternative definition
Andrew Gelman, David Dunson and Donald Rubin define observed information instead in terms of the parameters' posterior probability, :
Fisher information
The Fisher information is the expected value of the observed information given a single observation distributed according to the hypothetical model with parameter :

https://en.wikipedia.org/wiki/Heat%20shock%20protein%2047 | Heat shock protein 47, also known as SERPINH1 is a serpin which serves as a human chaperone protein for collagen.
Function
This protein is a member of the serpin superfamily of serine proteinase inhibitors. Its expression is induced by heat shock. HSP47 is expressed in the endoplasmic reticulum. These cells synthesize and secrete type I and type II collagen. The protein localizes to the endoplasmic reticulum lumen and binds collagen; thus it is thought to be a molecular chaperone involved in the maturation of collagen molecules. Autoantibodies to this protein have been found in patients with rheumatoid arthritis.
Interactions
Heat shock protein 47 has been shown to interact with collagens I, II, III, IV and V.
Research on role in preventing deep vein thrombosis
Research published in 2023 indicates a potential role of HSP47 regarding deep vein thrombosis. This initial research will be followed by additional studies.

https://en.wikipedia.org/wiki/Destination%20Calabria | "Destination Calabria" is a song by Italian music producer Alex Gaudino with vocals by Crystal Waters. It is the first single released from his debut album My Destination. The track is a mashup, taking the instrumental from Rune RK's "Calabria" and the vocals from Gaudino's and Waters' "Destination Unknown", both originally released in 2003. It was produced with the help of Maurizio Nari and Ronnie Milani (Nari & Milani), matching the saxophone riff from "Calabria" to Waters' voice.
In 2006, "Destination Calabria" was released in Italy as a 12-inch single by Rise Records. In the United Kingdom, a CD and 12-inch single were issued on 19 March 2007 by Data Records. The song was also successful in several other countries, including Australia, Belgium, France, Ireland, Spain, and the United Kingdom.
Music video
The music video is directed by Eran "Rani" Creevy, produced by Ben Pugh for Ministry of Sound and choreographed by David Leighton. It features eight female dancers (Natasha Payne, Jessica Fox, Emma Warton and more) in sexualized green marching band costumes, playing various instruments in a seductive manner, and dancing inside an infinity cove. In some scenes, seemingly hundreds of the dancers are seen at once, but these are simply the original eight replicated many times using digital imagery.
Waters herself does not appear in the video, but members of the marching band lip sync her lyrics at various points.

https://en.wikipedia.org/wiki/Gastric%20inhibitory%20polypeptide%20receptor | The gastric inhibitory polypeptide receptor (GIP-R), also known as the glucose-dependent insulinotropic polypeptide receptor, is a protein that in humans is encoded by the GIPR gene.
GIP-R is a member of the class B family of G protein coupled receptors. GIP-R is found on beta-cells in the pancreas where it serves as the receptor for the hormone Gastric inhibitory polypeptide (GIP).
Function
Gastric inhibitory polypeptide, also called glucose-dependent insulinotropic polypeptide, is a 42-amino acid polypeptide synthesized by K cells of the duodenum and small intestine. It was originally identified as an activity in gut extracts that inhibited gastric acid secretion and gastrin release, but subsequently was demonstrated to stimulate insulin release potently in the presence of elevated glucose. The insulinotropic effect on pancreatic islet beta-cells was then recognized to be the principal physiologic action of GIP. Together with glucagon-like peptide-1, GIP is largely responsible for the secretion of insulin after eating. It is involved in several other facets of the anabolic response.

https://en.wikipedia.org/wiki/Veterinary%20pathology | Veterinary pathologists are veterinarians who specialize in the diagnosis of diseases through the examination of animal tissue and body fluids. Like medical pathology, veterinary pathology is divided into two branches, anatomical pathology and clinical pathology. Other than the diagnosis of disease in food-producing animals, companion animals, zoo animals and wildlife, veterinary pathologists also have an important role in drug discovery and safety as well as scientific research.
Veterinary anatomical pathology
Anatomical pathology (Commonwealth) or Anatomic pathology (U.S.) is concerned with the diagnosis of disease based on the gross examination, microscopic, and molecular examination of organs, tissues, and whole bodies (necropsy). The Indian, European, Japanese and American Colleges of Veterinary Pathologists certify veterinary pathologists through a certifying exam. The American College of Veterinary Pathologist certification exam consists of four parts - gross pathology, microscopic pathology, veterinary pathology, and general pathology. Only the general pathology section is shared between the anatomic and clinical pathology examinations. Anatomic pathologists are employed in a number of different positions, including diagnostics, teaching, research, and the pharmaceutical industry.
Veterinary clinical pathology
Clinical pathology is concerned with the diagnosis of disease based on the laboratory analysis of bodily fluids such as blood, urine or cavitary effusions, or |
https://en.wikipedia.org/wiki/Oragene | Oragene is the trade name for DNA Genotek's non-invasive DNA self-collection kit. Oragene allows the collection, stabilization and long-term storage of DNA from saliva at ambient temperature. Oragene first became available to the genetic research community in 2004. Oragene is available in a variety of formats for various markets. In 2011, Oragene•Dx received 510(k) clearance from the U.S. Food and Drug Administration (FDA).
History
Oragene was invented by Dr. H. Chaim Birnboim. The basis for Oragene is outlined in his 1979 paper which described the widely used method of alkaline extraction of plasmid DNA from bacteria. For the first time, genetic researchers had access to a mechanism to collect large amounts of high quality DNA through non-invasive sampling. Prior to this discovery, the only option for those with this requirement was to use blood samples. Oragene allows donors to spit into a plastic tube to provide a reliable, high quality DNA sample in a non-invasive way.
Features
Oragene is used by academic research institutions, bone marrow donor registries, hospitals, clinical testing laboratories, and direct-to-consumer genetic testing companies who require large amounts of high quality DNA from a large number of donors. The non-invasive collection method offered by Oragene allows collection of DNA from those who might be unwilling to provide a blood sample. In addition, Oragene can be sent via the standard postal system providing the ability for customers to scale the |

https://en.wikipedia.org/wiki/Li%C3%A9nard%E2%80%93Wiechert%20potential | The Liénard–Wiechert potentials describe the classical electromagnetic effect of a moving electric point charge in terms of a vector potential and a scalar potential in the Lorenz gauge. Stemming directly from Maxwell's equations, these describe the complete, relativistically correct, time-varying electromagnetic field for a point charge in arbitrary motion, but are not corrected for quantum mechanical effects. Electromagnetic radiation in the form of waves can be obtained from these potentials. These expressions were developed in part by Alfred-Marie Liénard in 1898 and independently by Emil Wiechert in 1900.

https://en.wikipedia.org/wiki/Frequency%20scanning%20interferometry | Frequency scanning interferometry (FSI) is an absolute distance measurement technique, for measuring the distance between a pair of points, along a line-of-sight.
The power of the FSI technique lies in its ability to make many such distance measurements, simultaneously.
For each distance to be measured, a measurement interferometer is built using optical components placed at each end of a line-of-sight.
The optical path of each measurement interferometer is compared to the optical path in a reference interferometer, by scanning the frequency of a laser (connected to all interferometers in the system) and counting fringe cycles produced in the return signals from each interferometer.
The length of each measurement interferometer is given in units of reference length by the ratio of measurement interferometer to reference interferometer fringes.
To give an example: A frequency scan might produce 100 fringe cycles in the measurement interferometer and 50 in the reference interferometer. The measured interferometer is therefore twice the length of reference interferometer, to first order (ignoring systematic errors - see below).
Reference interferometer precautions
A typical reference interferometer is held at a stable length in a controlled environment, to reduce the dominant systematic errors which arise from changes in optical path which occur during the laser frequency scan.
Uses
The great strength of the FSI technique is the ability to simultaneously compare an |
https://en.wikipedia.org/wiki/Partitiviridae | Partitiviridae is a family of double-stranded RNA viruses. Plants, fungi, and protozoa serve as natural hosts. It has been suggested that they can also infect bacteria. The name comes from the Latin partitius, which means divided, and refers to the segmented genome of partitiviruses. There are five genera and 60 species in the family, 15 of which are unassigned to a genus.
Structure
Viruses in the family Partitiviridae are non-enveloped with icosahedral geometries and T=1 symmetry. The diameter of partitiviruses is around 25–43 nm.
Genome
Partitiviruses have double-stranded RNA genomes divided into two genomic segments, and there may be additional subgenomic segments. The two genome segments are packaged in separate virus particles. They code for two separate proteins. The first segment codes for the RNA-dependent RNA polymerase (RdRp), and the second segment codes for the coat protein. The segments are around 1.4–3.0 kbp in length, while the total genome length is around 3.0–4.8 kbp.
Life cycle
Viral replication is cytoplasmic. Entry into the host cell is achieved by penetration into the host cell. Replication follows the double-stranded RNA virus replication model. Double-stranded RNA virus transcription is the method of transcription. The virus exits the host cell by cell-to-cell movement. Fungi and plants serve as the natural host. Cryspoviruses infect apicomplexian protozoa of the genus Cryptosporidium, while viruses of the other genera infect plants and fungi. It |

Gene Leahy Mall in Downtown Omaha is named after him. His unorthodox style endeared him to many Omahans. He would often wear a clown suit for poor children's celebrations and he championed the retention of football at the University of Nebraska at Omaha when the Nebraska University System wanted to cut it.
Mayor Leahy was also well known for reading the Sunday comics on a local television station.
His long range planning for the city was done in a fashion which did not draw attention to his own guidance and vision yet has been one of the enduring backbones which the subsequent city leaders have built upon.

https://en.wikipedia.org/wiki/Gottschalk%20v.%20Benson | Gottschalk v. Benson, 409 U.S. 63 (1972), was a United States Supreme Court case in which the Court ruled that a process claim directed to a numerical algorithm, as such, was not patentable because "the patent would wholly pre-empt the mathematical formula and in practical effect would be a patent on the algorithm itself." That would be tantamount to allowing a patent on an abstract idea, contrary to precedent dating back to the middle of the 19th century. The ruling stated "Direct attempts to patent programs have been rejected [and] indirect attempts to obtain patents and avoid the rejection ... have confused the issue further and should not be permitted." The case was argued on October 16, 1972, and was decided November 20, 1972.
Prior history
The case revolves around a patent application filed by inventors Gary Benson and Arthur Tabbot, for a method for converting binary-coded decimal (BCD) numerals into pure binary numerals on a general-purpose digital computer. The patent examiner at the United States Patent Office, now called the U.S. Patent and Trademark Office or PTO, rejected the patent application as being directed to a mathematical expression. Pure mathematical expressions had been held to be unpatentable under earlier patent laws in Mackay Co. v. Radio Corp.
