https://en.wikipedia.org/wiki/Proximity%20effect%20%28audio%29 | The proximity effect in audio is an increase in bass or low frequency response when a sound source is close to a directional or cardioid microphone. Proximity effect is a change in the frequency response of a directional pattern microphone that results in an emphasis on lower frequencies. It is caused by the use of ports to create directional polar pickup patterns, so omni-directional microphones do not exhibit the effect (this is not necessarily true of the "omni" pattern on multipattern condenser mics, which create the "omni" pattern by summing two back-to-back cardioid capsules, which may or may not share a common backplate.)
Proximity effect can be viewed in two ways. In some settings, sound engineers may view it as undesirable, and so the type of microphone or microphone practice may be chosen in order to reduce the proximity effect. On the other hand, some microphone users seek to intentionally use the proximity effect, such as beat boxing singers in hip hop music.
Technical explanation
Depending on the microphone design, proximity effect may result in a boost of up to 16 dB or more at lower frequencies, depending on the size of the microphone's diaphragm and the distance of the source.
A ready (and common) example of proximity effect can be observed with cardioid dynamic vocal microphones (though it is not limited to this class of microphone) when the vocalist is very close to or even touching the mic with their lips. The effect is heard as a 'fattening up' of the v |

https://en.wikipedia.org/wiki/V-erbA-related%20gene | V-erbA-related protein 2 (EAR-2) also known as NR2F6 (nuclear receptor subfamily 2 group F member 6) is a protein that in humans is encoded by the NR2F6 gene. V-erbA-related protein 2 is a member of the nuclear receptor family of intracellular transcription factors. It is named after its similarity to v-erbA (), a helper of an oncoprotein called v-erbB in avian erythroblastosis virus.
Function
Comparatively little is known about ear-2, but it has been shown to function as a coregulator of other nuclear receptors.
Nr2f6 knockout mice show defects in development of the locus ceruleus.
It was found that antigen receptor stimulation-induced NF-AT/AP-1 activity is regulated through the nuclear receptor NR2F6 (NR2F6 acts as a direct repressor of NF-AT/AP-1 transactivation) and that by preventing NR2F6 function, transcriptional activation of NF-AT/AP-1 is enhanced in immune cells which leads to an augmented immune response.
NR2F6 impairs the formation of mature red blood cells in animals that over-express NR2F6 in their bone marrow. Mice that over expression of NR2F6 in their bone marrow cells have a block at the pro-erythroblast stage of blood cell development both in the bone marrow and in the spleen of animals that have excessive expression of NR2F6. So, when inhibition of differentiation of stem cell is desired, inhibition of differentiation is achieved through induction of increased NR2F6 activity.

https://en.wikipedia.org/wiki/Nerve%20tissue%20protein | Nerve tissue is a biological molecule related to the function and maintenance of normal nervous tissue. An example would include, for example, the generation of myelin which insulates and protects nerves. These are typically calcium-binding proteins.
Myelination and peripheral nervous system
There are two types of myelin. The first is oligodendrocyte, which can be found in the mammalian Central Nervous System (CNS). The second is Schwann cells, which are found in the Peripheral Nervous System (PNS). Myelination of axons by these Schwann cells are essential for normal nerve function. Peripheral nerves rely on communication between axons and Schwaan cells.
Maintenance of myelin
Prion protein triggers are an important factor in the signals that ensure myelin maintenance and are distinct from those that direct myelination. Prion protein and antibodies POM1 and POM3, which recognize epitopes in the terminus (around amino acids (aa) 140–152) and charged clusters of prion protein (aa95-100) were used to their role in myelin maintenance. The result indicated that neuronal expression and regulated proteolysis of prion protein are essential for myelin maintenance.
Neurodegenerative disease
Neurodegenerative disease is caused by prions accumulation of PrPsc. The brains of humans or animals affected with prion disease show characteristics histopathological changes. However, the pathogenesis of the disease is largely unknown and treatment is often unsatisfactory. Tests on 60-week-old |
https://en.wikipedia.org/wiki/WUUQ | WUUQ (97.3 FM) is a radio station serving the Chattanooga, Tennessee area, broadcasting on two different frequencies. The main frequency is 97.3 MHz FM which is licensed to South Pittsburg, Tennessee. 99.3 FM is a translator station licensed to Lookout Mountain, Tennessee with the call-sign W257AZ. The three numbers in the call letters of an FM translator indicate the frequency. This station currently broadcasts a Classic Country format known as "Classic Country Q97.3★Q99.3". These stations are owned by Bahakel Communications. Libby Phillips is General Manager and Dale Mitchell is Operations Manager/Program Director.
WUUQ's studios are located on Broad Street in Chattanooga, and its transmitter is located in the far northeast corner of Alabama, just south of the Tennessee state line.
History
In 1999, Cumulus owned rhythmic oldies WLOV (formerly WKXJ) at 97.3 FM, as well as WUSY, WKXJ, WLMX-FM and WLMX (AM). In 2000, Cumulus announced it would buy 11 radio stations in 4 markets from Clear Channel Communications (now iHeartMedia) in exchange for 25 radio stations in 5 markets plus cash. WLOV, WIIS, WUSY, WKXJ and WLMX-FM were included in those stations going to Clear Channel.
When the 97.3 frequency was still licensed to Clear Channel, WLOV was urban contemporary and also heard on 99.3 FM. The 980 frequency was sports talk. Other Clear Channel stations were WKXJ, WRXR-FM (the former WLMX-FM), WUUS (the former WLMX (AM)), WSGC, & WUSY.

https://en.wikipedia.org/wiki/TLX | Nuclear receptor TLX (homologue of the Drosophila tailless gene) also known as NR2E1 (Nuclear receptor subfamily 2 group E member 1) is a protein that in humans is encoded by the NR2E1 gene. TLX is a member of the nuclear receptor family of intracellular transcription factors.
Function
TLX regulates the expression of another nuclear receptor, RAR.
TLX also is essential for normal brain-eye coordination and appears to play a role in control of aggressive behavior.
Adult neural stem cells are nuclear receptor TLX-positive and TLX expression in these cells is crucial in maintaining their undifferentiated state. Furthermore, TLX regulates adult neural stem cell proliferation. Removal of TLX from the adult mouse brain resulted in a reduction of stem cell proliferation and spatial learning.
Tlx-positive cells of the subventricular zone of adult mouse brain are self-renewing stem cells. Mutation of the Tlx gene in adult mouse brain leads to complete loss of neurogenesis in the subventricular zone. Tlx is also required for transition from radial glial cells to astrocyte-like neural stem cells.
Ligands
TLX belongs to a small family of NRs that lack two helices in the ligand-binding domain, forming an enlarged binding pocket. Three compounds, termed ccrp1–3 (famprofazone, 1-(1,5-dimethylpyrazole-3-carbonyl)-4-(diphenylmethyl)piperazine, dydrogesterone), have been discovered in high-throughput screening that enhance TLX's ability of transcription repression with high potency.

https://en.wikipedia.org/wiki/Photoreceptor%20cell-specific%20nuclear%20receptor | The photoreceptor cell-specific nuclear receptor (PNR), also known as NR2E3 (nuclear receptor subfamily 2, group E, member 3), is a protein that in humans is encoded by the NR2E3 gene. PNR is a member of the nuclear receptor super family of intracellular transcription factors.
Function
PNR is exclusively expressed in the retina. The main target genes of PNR are rhodopsin and several opsins which are essential for sight.
Structure and ligands
The crystal structure of PNR's ligand-binding domain is known. It self-dimerizes into, by default, a repressor state. Computer simulations based on this model shows that a ligand could possibly fit into PNR and switch it into a transcription activator. 13-cis retinoic acid is a known weak agonist that fits into such a pocket, but no physiologic ligand is known. Two synthetic compounds, 11A and 11B, appear to be agonists but do not go into the pocket and instead work as allosteric modulators. A more recent screening identifies another compound called photoregulin-1 (PR1) that functions as a reverse agonist, an activity possibly useful in the management of retinitis pigmentosa.
Clinical significance
Mutations in the NR2E3 gene have been linked to several inherited retinal diseases, including enhanced S-cone syndrome (ESCS), a form of retinitis pigmentosa, and Goldmann-Favre syndrome.

https://en.wikipedia.org/wiki/Espresso%20heuristic%20logic%20minimizer | The ESPRESSO logic minimizer is a computer program using heuristic and specific algorithms for efficiently reducing the complexity of digital logic gate circuits. ESPRESSO-I was originally developed at IBM by Robert K. Brayton et al. in 1982. and improved as ESPRESSO-II in 1984. Richard L. Rudell later published the variant ESPRESSO-MV in 1986 and ESPRESSO-EXACT in 1987. Espresso has inspired many derivatives.
Introduction
Electronic devices are composed of numerous blocks of digital circuits, the combination of which performs the required task. The efficient implementation of logic functions in the form of logic gate circuits (such that no more logic gates are used than are necessary) is necessary to minimize production costs, and/or maximize a device's performance.
Designing digital logic circuits
All digital systems are composed of two elementary functions: memory elements for storing information, and combinational circuits that transform that information. State machines, like counters, are a combination of memory elements and combinational logic circuits. Since memory elements are standard logic circuits they are selected out of a limited set of alternative circuits; so designing digital functions comes down to designing the combinational gate circuits and interconnecting them.
In general the instantiation of logic circuits from high-level abstraction is referred to as logic synthesis, which can be carried out by hand, but usually some formal method by computer is ap |
https://en.wikipedia.org/wiki/Green%20measure | In mathematics — specifically, in stochastic analysis — the Green measure is a measure associated to an Itō diffusion. There is an associated Green formula representing suitably smooth functions in terms of the Green measure and first exit times of the diffusion. The concepts are named after the British mathematician George Green and are generalizations of the classical Green's function and Green formula to the stochastic case using Dynkin's formula.
Notation
Let X be an Rn-valued Itō diffusion satisfying an Itō stochastic differential equation of the form
Let Px denote the law of X given the initial condition X0 = x, and let Ex denote expectation with respect to Px. Let LX be the infinitesimal generator of X, i.e.
Let D ⊆ Rn be an open, bounded domain; let τD be the first exit time of X from D:
The Green measure
Intuitively, the Green measure of a Borel set H (with respect to a point x and domain D) is the expected length of time that X, having started at x, stays in H before it leaves the domain D. That is, the Green measure of X with respect to D at x, denoted G(x, ·), is defined for Borel sets H ⊆ Rn by
or for bounded, continuous functions f : D → R by
The name "Green measure" comes from the fact that if X is Brownian motion, then
where G(x, y) is Green's function for the operator LX (which, in the case of Brownian motion, is ½Δ, where Δ is the Laplace operator) on the domain D.

Suppose that Ex[τD] < +∞ for all x ∈ D, and let f : Rn → R be |
https://en.wikipedia.org/wiki/Discriminative%20model | Discriminative models, also referred to as conditional models, are a class of logistical models used for classification or regression. They distinguish decision boundaries through observed data, such as pass/fail, win/lose, alive/dead or healthy/sick.
Typical discriminative models include logistic regression (LR), conditional random fields (CRFs) (specified over an undirected graph), decision trees, and many others. Typical generative model approaches include naive Bayes classifiers, Gaussian mixture models, variational autoencoders, generative adversarial networks and others.
Definition
Unlike generative modelling, which studies the joint probability , discriminative modeling studies the or maps the given unobserved variable (target) to a class label dependent on the observed variables (training samples). For example, in object recognition, is likely to be a vector of raw pixels (or features extracted from the raw pixels of the image). Within a probabilistic framework, this is done by modeling the conditional probability distribution , which can be used for predicting from . Note that there is still distinction between the conditional model and the discriminative model, though more often they are simply categorised as discriminative model.

https://en.wikipedia.org/wiki/EcosimPro | EcosimPro is a simulation tool developed by Empresarios Agrupados A.I.E for modelling simple and complex physical processes that can be expressed in terms of Differential algebraic equations or Ordinary differential equations and Discrete event simulation.
The application runs on the various Microsoft Windows platforms and uses its own graphic environment for model design.
The modelling of physical components is based on the EcosimPro language (EL) which is very similar to other conventional Object-oriented programming languages but is powerful enough to model continuous and discrete processes.
This tool employs a set of libraries containing various types of components (mechanical, electrical, pneumatic, hydraulic, etc.) that can be reused to model any type of system.
It is used within ESA for propulsion systems analysis and is the recommended ESA analysis tool for ECLS systems.
Origins
The EcosimPro Tool Project began in 1989 with funds from the European Space Agency (ESA) and with the goal of simulating environmental control and life support systems for crewed spacecraft, such as the Hermes shuttle.
The multidisciplinary nature of this modelling tool led to its use in many other disciplines, including fluid mechanics, chemical processing, control, energy, propulsion and flight dynamics. These complex applications have demonstrated that EcosimPro is very robust and ready for use in many other fields.

https://en.wikipedia.org/wiki/Whirlwind | A whirlwind is a phenomenon in which a vortex of wind (a vertically oriented rotating column of air) forms due to instabilities and turbulence created by heating and flow (current) gradients. Whirlwinds can vary in size and last from a couple minutes to a couple hours.
Types
Whirlwinds are subdivided into two main types, the great (or major) whirlwinds, and the lesser (or minor) whirlwinds. The first category includes tornadoes, waterspouts, and landspouts. The range of atmospheric vortices constitute a continuum and are difficult to categorize definitively. Some lesser whirlwinds may sometimes form in a similar manner to greater whirlwinds with related increase in intensity. These intermediate types include the gustnado and the fire whirl. Other lesser whirlwinds include dust devils, as well as steam devils, snow devils, debris devils, leaf devils or hay devils, water devils, and shear eddies such as the mountainado and eddy whirlwinds.
Formation
A major whirlwind (such as a tornado) is formed from supercell thunderstorms (the most powerful type of thunderstorm) or other powerful storms. When the storms start to spin, they react with other high altitude winds, causing a funnel to spin. A cloud forms over the funnel, making it visible.
A minor whirlwind is created when local winds start to spin on the ground. This causes a funnel to form. The funnel moves over the ground, pushed by the winds that first formed it. The funnel picks up materials such as dust or sn |

https://en.wikipedia.org/wiki/Desert%20long-eared%20bat | The desert long-eared bat (Otonycteris hemprichii) is a species of vesper bat found in North Africa and the Middle East.
Taxonomy
The taxonomic classification of Otonycteris is unclear, however their chromosomes suggest that this genus is closely related to the Barbastella and Plecotus genera.
Description
It has a body and head length of about 73-81 mm (2.9-3.2 in); a forearm length of about , and a tail length of about . Male desert long-eared bats weigh . They have nearly horizontally directed ears, which use a band of skin to connect across the forehead and are about 40 mm in length. The desert long-eared bat has a pale sandy and dark brown upper part, with a whitish bottom. It has a similar skull and similar teeth to the Eptesicus. Some specimens of this species have two sets of mammae in their pectoral muscles, which is unique for mammals. These mammae may not be functional.
Ecology and behavior
This species normally inhabits dry, arid, rocky, and barren regions. One pair of these bats was found living in a hill's crevice in the Negev Desert. This bat has also been found in buildings.
Otonycteris hemprichii has a flight pattern described as "floppy and slow".
Diet
This species is assumed to be carnivorous due to its body mass, low wing loading, and low aspect ratio. This bat likely forages close to the ground, using echolocation to detect large flying or surface-dwelling invertebrates. Through echolocation, the bats can detect scorpions as they walk.

https://en.wikipedia.org/wiki/Iodoacetic%20acid | Iodoacetic acid is a derivative of acetic acid. It is a toxic compound, because, like many alkyl halides, it is an alkylating agent.
It reacts with cysteine residues in proteins. It is often used to modify SH-groups to prevent the re-formation of disulfide bonds after the reduction of cystine residues to cysteine during protein sequencing.
In 1929, Dr. Einar Lundsgaard (1899-1968) discovered that muscle poisoned in vitro with iodoacetic acid is unable to produce lactate as glycolysis from muscle glycogen is blocked, causing the muscle to result in an electrically silent contracture. It was remembering this discovery, that lead Dr. Brian McArdle in 1951, to speculate that one of his patients that had electromyographically silent muscle contractures brought on by high-intensity aerobic activity and anaerobic activity must have a defective muscle glycogen mechanism.
Peptidase inhibitor
Iodoacetate is an irreversible inhibitor of all cysteine peptidases, with the mechanism of inhibition occurring from alkylation of the catalytic cysteine residue (see schematic). In comparison with its amide derivative, iodoacetamide, iodoacetate reacts substantially slower. This observation appears contradictory to standard chemical reactivity, however the presence of a favourable interaction between the positive imidazolium ion of the catalytic histidine and the negatively charged carboxyl-group of the iodoacetic acid is the reason for the increased activity of iodoacetamide.

https://en.wikipedia.org/wiki/EIA%20RF%20Connectors | EIA RF Connectors are used to connect two items of high power radio frequency rigid or semi-rigid (flexline) coaxial transmission line. Typically these are only required in very high power transmitting installations (above 3kW at VHF to MW) where the feedline diameters may be several inches. The connectors are always female, requiring a male coupling element or bullet to make the connection. The EIA under the Electronic Components Industry Association (http://www.ecianow.org/), are responsible for a number of standard imperial connector sizes.
Dimensions
The flange design, inner and outer conductor dimensions are standardized, by EIA, in the RS-225, 50 Ω (ohm), and RS-259, 75 Ω, standards. They are commonly referred to by the inner diameter of the outer conductor in fractional inches. Sizes covered under these two standards range from 3/8 to 6 1/8 inch outside diameter (OD) for 50 Ω and 3/8 to 3 1/8 inch OD for 75 Ω.
Peak pulse power handling, driven by voltage breakdown, is more or less frequency independent for any given size (and can be deduced by assuming ~300 V RMS per mm of inner to outer spacing), but the average power, limited by losses heating the centre conductors, increases approximately with the square root of the operating frequency. Commonly the limit is quoted as that dissipation that will raise the inner temperature to 100 °C when the outer is maintained constant at +40 °C. Field failures can occur at power levels well below this if the central bullet conne |

https://en.wikipedia.org/wiki/Laura%20%28novel%29 | Laura (1943) is a detective novel by Vera Caspary. It is her best known work, and was adapted into a popular film in 1944, with Gene Tierney in the title role.
Publication history
Originally, Laura ran in Colliers from October to November 1942 as a seven-part serial titled Ring Twice for Laura. Houghton Mifflin republished Laura in book form the next year; afterwards, Caspary sold the film rights to Twentieth Century Fox, resulting in a 1944 hit movie starring Gene Tierney and Dana Andrews. In 1946, Caspary sold the story for a fourth time, this time co-writing a theatrical version with George Sklar.
Laura achieved an international readership and has been translated into German, Italian, Japanese and Dutch, and it was released as an Armed Services Edition for the American military during World War II. Since its original publication, the novel has been reissued many times. I Books released an edition in 2000, billing it as a "lost classic;" however, this edition is out of print. An edition from Feminist Press became available in 2006.
In 2015, it was included as part of the Library of America's Women Crime Writers omnibus collection.
Plot introduction
Like Wilkie Collins' novel The Woman in White (1859), Laura is narrated in the first person by several alternating characters. These individual stories all revolve around the apparent murder of the title character, a successful New York advertiser killed in the doorway of her apartment with a shotgun blast that obliterated |
https://en.wikipedia.org/wiki/Marginellidae | Marginellidae, or the margin shells, are a taxonomic family of small, often colorful, sea snails, marine gastropod molluscs in the clade Neogastropoda.
Taxonomy
The higher classification of the family Marginellidae has long been in a state of confusion. Many popular works still treat all members of this family under the single genus Marginella, basing them primarily on superficial similarities of the shell.
The confusion over the classification stems from the fact that the earlier classifications were based rather crudely on shell characters. Although many good differential shell characters do exist within this group, those characters were generally misinterpreted or not recognized as significant. Such information as did exist on the radulae and the external anatomy of the living animals was widely scattered in the scientific literature, and internal anatomical descriptions were not available until fairly recently.
In 2019 a new molecular phylogeny of marginelliform gastropods has been established by Fedosov A.E., Caballer Gutierrez M., Buge B., Sorokin P.V., Puillandre N., Bouchet P.
Shell description
The shell of Marginellidae is usually small, but varies in different species from minute to medium-sized.
The external color of the shell can be white, cream, yellow, orange, red, or brown, and can be uniformly colored, or patterned in various ways. The protoconch is paucispiral. The lip of the shell is thickened, and can be smooth or denticulate. An external varix may be |

Let X : T × Ω → S be a stochastic process defined for "times" t in some ordered index set T, on a probability space (Ω, Σ, P), and taking values in a measurable space S. Let ζ : Ω → T be a random time, referred to as the killing time. Then the killed process Y associated to X is defined by
and Yt is left undefined for t ≥ ζ. Alternatively, one may set Yt = c for t ≥ ζ, where c is a "coffin state" not in S.

Biography
McDonald joined the Army from Beckley, West Virginia in 1967, and served as a private first class in Company A, 1st Battalion, 14th Infantry Regiment, 4th Infantry Division. He was posthumously awarded the Medal of Honor for his actions during a June 7, 1968 firefight near Kontum in South Vietnam, during Operation MacArthur.
McDonald, aged 26 at his death, was buried in Guilford Memorial Park, Greensboro, North Carolina.
For conspicuous gallantry and intrepidity in action at the risk of his life above and beyond the call of duty. Pfc. McDonald distinguished himself while serving as a team leader with the 1st platoon of Company A. While on a combat mission his platoon came under heavy barrage of automatic weapons fire from a well concealed company-size enemy force. Volunteering to escort 2 wounded comrades to an evacuation point, Pfc. McDonald crawled through intense fire to destroy with a grenade an enemy automatic weapon threatening the safety of the evacuation. Returning to his platoon, he again volunteered to provide covering fire for the maneuver of the platoon from its exposed position. Realizing the threat he posed, enemy gunners concentrated their fire on Pfc. McDonald's position, seriously wounding him. Despite his painful wounds, Pfc. McDonald rec |
https://en.wikipedia.org/wiki/Petromyscus | Petromyscus is a genus of rodent in the family Nesomyidae. It is so distinct from other rodents that it is placed as the only genus in subfamily Petromyscinae. In previous classifications, Delanymys brooksi has also been placed in the subfamily. They are found in southwestern Africa. These animals have a sharp lower point to their V-shaped infraorbital canal. Their molars are intermediate between the ancestral cricetid style tooth and the dendromurine style tooth.
The genus contains the following species:
Barbour's rock mouse (Petromyscus barbouri)
Pygmy rock mouse (Petromyscus collinus)
Brukkaros pygmy rock mouse (Petromyscus monticularis)
Shortridge's rock mouse (Petromyscus shortridgei)

https://en.wikipedia.org/wiki/Mezoneuron%20kauaiense | Mezoneuron kauaiense is a rare shrub or small tree in the genus Mezoneuron (pea family, Fabaceae), that is endemic to Hawaii. Common names include uhiuhi (the Big Island and Kauai), kāwau (Maui), and kea (Maui). It is threatened by invasive species, particularly feral ungulates.
Description
Mezoneuron kauaiense is a shrub or small tree that reaches a height of . The bark is dark grey and made up of rectangular or oblong platelets. The pinnate leaves are composed of 4 to 8 leaflets, each around in length. The bisexual flowers have pink to rose sepals and red anthers. They form on pink to red terminal racemes in length. The flat, thin seed pods are long, wide, and contain 2 to 4 oval-shaped seeds. Blooming takes place from December to March.
Habitat
Uhiuhi inhabits dry, coastal mesic, and mixed mesic forests at elevations of . Associated plants include lama (Diospyros sandwicensis), aalii (Dodonaea viscosa), and alahee (Psydrax odorata). Populations formerly existed on Kauai (Waimea Canyon), West Maui, Lānai, the Big Island (North Kona District), and Oahu (Waianae Range), but are only found in the latter two today.
Uses
The wood of M. kauaiense is very dense and hard, nearly black, and close-grained. Native Hawaiians used it to make ōō (digging sticks), ihe (spears), laau melomelo (fishing lures), pou (house posts), runners for papa hōlua (sleds), pāhoa (daggers), laau palau (clubs), and laau kahi wauke (Broussonetia papyrifera scraping boards).

https://en.wikipedia.org/wiki/List%20of%20Major%20League%20Baseball%20career%20stolen%20bases%20leaders | In baseball statistics, a stolen base is credited to a baserunner when he successfully advances to the next base while the pitcher is throwing the ball to home plate. Under Rule 7.01 of Major League Baseball's (MLB) Official Rules, a runner acquires the right to an unoccupied base when he touches it before he is out. Stolen bases were more common in baseball's dead-ball era, when teams relied more on stolen bases and hit and run plays than on home runs.
Rickey Henderson holds the MLB career stolen base record with 1,406. He is the only MLB player to have reached the 1,000 stolen bases milestone in his career. Following Henderson is Lou Brock with 938 stolen bases; Billy Hamilton is third on the all-time steals listing. The number of career steals attributed to Hamilton varies by source, but all sources hold his career steals placing him in third on the list before Ty Cobb (897), Tim Raines (808), Vince Coleman (752), Arlie Latham (742), Eddie Collins (741), Max Carey (738), and Honus Wagner (723), who are the only other players to have stolen at least 700 bases. Coleman is the leader for retired players that are not members of the Hall of Fame.Brock held the all-time career stolen bases before being surpassed by Henderson in 1991. Brock had held the record from 1977 to 1991. Before Brock, Hamilton held the record for eighty-one years, from 1897 to 1977. Before that, Latham held the record from 1887 to 1896. Latham was also the first player to collect 300 career stolen bases. |
https://en.wikipedia.org/wiki/Eikonal%20approximation | In theoretical physics, the eikonal approximation (Greek εἰκών for likeness, icon or image) is an approximative method useful in wave scattering equations which occur in optics, seismology, quantum mechanics, quantum electrodynamics, and partial wave expansion.
Informal description
The main advantage that the eikonal approximation offers is that the equations reduce to a differential equation in a single variable. This reduction into a single variable is the result of the straight line approximation or the eikonal approximation which allows us to choose the straight line as a special direction.
Relation to the WKB approximation
The early steps involved in the eikonal approximation in quantum mechanics are very closely related to the WKB approximation for one-dimensional waves. The WKB method, like the eikonal approximation, reduces the equations into a differential equation in a single variable. But the difficulty with the WKB approximation is that this variable is described by the trajectory of the particle which, in general, is complicated.
Formal description
Making use of WKB approximation we can write the wave function of the scattered system in terms of action S:
Inserting the wavefunction Ψ in the Schrödinger equation without the presence of a magnetic field we obtain
We write S as a power series in ħ
For the zero-th order:
If we consider the one-dimensional case then .
We obtain a differential equation with the boundary condition:

It is known as a small nucleolar RNA (snoRNA) and also often referred to as a 'guide RNA'.
R9 is a member of the C/D box class of snoRNAs which contain the conserved sequence motifs known as the C box (UGAUGA) and the D box (CUGA). Most of the members of the box C/D family function in directing site-specific 2'-O-methylation of substrate RNAs.
This plant snoRNA was identified in Arabidopsis thaliana by computational screening and experimentally verified by primer extension analysis. This snoRNA is not related to the snoRNA identified in hyperthermophiles also called snoR9.

https://en.wikipedia.org/wiki/RealFlow | RealFlow is a fluid and dynamics simulation tool for the 3D and visual effects industry, developed by Next Limit Technologies in Madrid, Spain. This stand-alone application can be used in conjunction with other 3D programs to simulate fluids, water surfaces, fluid-solid interactions, rigid bodies, soft bodies and meshes. In 2008, Next Limit Technologies was awarded a Technical Achievement Award by the Academy of Motion Picture Arts and Sciences for their development of the RealFlow software and its contribution to the production of motion pictures. In 2015, Next Limit Technologies announced the release of RealFlow Core for Cinema 4D.
Overview
RealFlow technology uses particle based simulations. These particles can be influenced in various ways by point-based nodes (daemons) which can do various tasks such as simulate gravity or recreate the vortex-like motion of a tornado. RealFlow can also simulate soft and rigid body collisions and interactions. The inclusion of Python scripting and C++ plug-ins allows users to program their own tools to improve RealFlow capabilities, adding control to most aspects of the RealFlow workflow including batch runs, events, daemons, waves, and fluids.
The RealFlow Renderkit (RFRK) is a set of tools designed to facilitate the rendering of fluids. The RFRK enables the generation of procedural geometry at render time and the rendering of individual fluid particles. With this interface, fluids can also be rendered as foam and spray.

https://en.wikipedia.org/wiki/Solid%20harmonics | In physics and mathematics, the solid harmonics are solutions of the Laplace equation in spherical polar coordinates, assumed to be (smooth) functions . There are two kinds: the regular solid harmonics , which are well-defined at the origin and the irregular solid harmonics , which are singular at the origin. Both sets of functions play an important role in potential theory, and are obtained by rescaling spherical harmonics appropriately:
Derivation, relation to spherical harmonics
Introducing , , and for the spherical polar coordinates of the 3-vector , and assuming that is a (smooth) function , we can write the Laplace equation in the following form

It is known that spherical harmonics are eigenfunctions of :
Substitution of into the Laplace equation gives, after dividing out the spherical harmonic function, the following radial equation and its general solution,
The particular solutions of the total Laplace equation are regular solid harmonics:

https://en.wikipedia.org/wiki/Blue-black%20grosbeak | The blue-black grosbeak (Cyanoloxia cyanoides) is a species of songbird in the family Cardinalidae.
The South American Classification Committee of the American Ornithological Society places this species in genus Cyanoloxia. In addition, in 2018 the committee split the eastern lowland population into a new species, Amazonian grosbeak (Cyanoloxia rothschildii).
Taxonomy and systematics
The blue-black grosbeak is found in the family Cardinalidae, within the order Passeriformes. Although it is still sometimes placed in the genus Cyanocompsa, it was found that this genus is paraphyletic and contains members of the genus Amaurospiza and Cyanoloxia.
There are three subspecies in this taxa: Cyanoloxia cyanoides cyanoides, Cyanoloxia cyanoides caerulescens, and Cyanoloxia cyanoides concreta. Although these three subspecies are very similar, there are slight differences between them. Males all have dark blue plumage, however, C.c. concreta has the darkest of the three and is also the largest. Next, in terms of size and coloration, is C.c. caerulescens, followed by C.c. cyanoides, which has the smallest size and brightest plumage.
Originally there was a fourth subspecies, C.c. rothschildii, the only subspecies found to the east of the Andes. However, after examining the genetics of this subspecies, it was determined that C.c. rothschildii would be considered a separate species, Cyanoloxia rothschildii.

https://en.wikipedia.org/wiki/Newton%27s%20theorem%20of%20revolving%20orbits | In classical mechanics, Newton's theorem of revolving orbits identifies the type of central force needed to multiply the angular speed of a particle by a factor k without affecting its radial motion (Figures 1 and 2). Newton applied his theorem to understanding the overall rotation of orbits (apsidal precession, Figure 3) that is observed for the Moon and planets. The term "radial motion" signifies the motion towards or away from the center of force, whereas the angular motion is perpendicular to the radial motion.
Isaac Newton derived this theorem in Propositions 43–45 of Book I of his Philosophiæ Naturalis Principia Mathematica, first published in 1687. In Proposition 43, he showed that the added force must be a central force, one whose magnitude depends only upon the distance r between the particle and a point fixed in space (the center). In Proposition 44, he derived a formula for the force, showing that it was an inverse-cube force, one that varies as the inverse cube of r. In Proposition 45 Newton extended his theorem to arbitrary central forces by assuming that the particle moved in nearly circular orbit.
As noted by astrophysicist Subrahmanyan Chandrasekhar in his 1995 commentary on Newton's Principia, this theorem remained largely unknown and undeveloped for over three centuries. Since 1997, the theorem has been studied by Donald Lynden-Bell and collaborators. Its first exact extension came in 2000 with the work of Mahomed and Vawda.

https://en.wikipedia.org/wiki/Indian%20Outlaw | "Indian Outlaw" is a song written by Tommy Barnes, Jumpin' Gene Simmons and John D. Loudermilk, and performed by American country music artist Tim McGraw. It was released in January 1994 as the first single from his album Not a Moment Too Soon. It was McGraw's breakthrough single, his first Top 40 country hit, and his fourth single overall. It peaked at number 8 on the Billboard Hot Country Singles & Tracks charts, and number 15 on the Billboard Hot 100.
Content
The song is an up-tempo set in minor key, backed by tom-tom drums and fiddle. The narrator describes himself as a rebellious American Indian character, "Half Cherokee and Choctaw". He describes, among other things, his pursuit of a Chippewa lover.
The song contains a sample of John D. Loudermilk's song "Indian Reservation", which is sung as shouting at the end ("Cherokee people, Cherokee tribe! / So proud to live, so proud to die").
A dance remix of the single was also made. This remix appears on McGraw's 2010 album Number One Hits.
The song was considered controversial at the time, due to its stereotypical portrayal of Native Americans; as a result, some radio stations refused to play it.
Critical reception
Larry Flick of Billboard called it an "incredible single" that is "positively stuffed with lyrical and musical Native American cliches, from tomtoms to wigwams to peace pipes." He went on to say that if the song became a hit, it would "set relations back 200 years." In a review of Not a Moment Too Soon for |

https://en.wikipedia.org/wiki/Chromatin%20remodeling | Chromatin remodeling is the dynamic modification of chromatin architecture to allow access of condensed genomic DNA to the regulatory transcription machinery proteins, and thereby control gene expression. Such remodeling is principally carried out by 1) covalent histone modifications by specific enzymes, e.g., histone acetyltransferases (HATs), deacetylases, methyltransferases, and kinases, and 2) ATP-dependent chromatin remodeling complexes which either move, eject or restructure nucleosomes. Besides actively regulating gene expression, dynamic remodeling of chromatin imparts an epigenetic regulatory role in several key biological processes, egg cells DNA replication and repair; apoptosis; chromosome segregation as well as development and pluripotency. Aberrations in chromatin remodeling proteins are found to be associated with human diseases, including cancer. Targeting chromatin remodeling pathways is currently evolving as a major therapeutic strategy in the treatment of several cancers.
Overview
The transcriptional regulation of the genome is controlled primarily at the preinitiation stage by binding of the core transcriptional machinery proteins (namely, RNA polymerase, transcription factors, and activators and repressors) to the core promoter sequence on the coding region of the DNA. However, DNA is tightly packaged in the nucleus with the help of packaging proteins, chiefly histone proteins to form repeating units of nucleosomes which further bundle together to form |

During his years at Washington University in St. Louis, he also led efforts to develop yeast artificial chromosomes that allowed for the study of large portions of the human genome.
Early life and education
Olson was born and raised in Bethesda, Maryland, where he was educated through their public school system. Upon graduating from high school, he received his undergraduate degree from California Institute of Technology (Caltech) and his doctoral degree in inorganic chemistry from Stanford University in 1970. During his time at Caltech, he attended lectures by Richard Feynman which he said was a "memorable experience."
Career
Upon graduating with his PhD, Olson worked at Dartmouth College as an inorganic chemist but experienced "an early mid-life crisis" and chose to change fields. Olsen decided to begin work on genomics in the 1970’s, after being reading Molecular Biology of the Gene, by James Watson. He subsequently took a sabbatical and worked with Benjamin Hall at the University of Washington (UW) in Seattle. In 1979, he accepted a position at Washington University in St. Louis (WUSTL), where he began to work on the development of systematic approaches to the analysis of complex genomes.

Plot
In Dallas, Walter Lloyd runs a lumber business. After checking out at the office, Walter stops by the local racetrack, where his college-age son Chris works repairing stock cars. He reminds Chris of his mother's departure for Europe that afternoon, and Chris meets him back at the house to send her off.
Though their relationship is slightly strained, the family is tightly woven and carry on amicably, although an underlying tension between father and son is hinted at. Before she leaves, Chris' mother asks Walter to "break through to the kid." Walter attempts to bond with Chris over the next few days, Chris staying at the house and going on a fishing trip with Walter.
That night, the two are awoken by a late-night phone call from Paris informing Walter that his wife has split from her tour group. Although he downplays it, Walter's fear for his wife's well-being is apparent and Chris picks up on it. Prying further, Chris gets Walter to admit that she has, in fact, been missing for two days. With that, Chris and Walter decide to go to Paris to find her.

https://en.wikipedia.org/wiki/Haj%C3%B3s%27s%20theorem | In group theory, Hajós's theorem states that if a finite abelian group is expressed as the Cartesian product of simplexes, that is, sets of the form where is the identity element, then at least one of the factors is a subgroup. The theorem was proved by the Hungarian mathematician György Hajós in 1941 using group rings. Rédei later proved the statement when the factors are only required to contain the identity element and be of prime cardinality. Rédei's proof of Hajós's theorem was simplified by Tibor Szele.
An equivalent statement on homogeneous linear forms was originally conjectured by Hermann Minkowski. A consequence is Minkowski's conjecture on lattice tilings, which says that in any lattice tiling of space by cubes, there are two cubes that meet face to face. Keller's conjecture is the same conjecture for non-lattice tilings, which turns out to be false in high dimensions.

https://en.wikipedia.org/wiki/Dean%20number | The Dean number (De) is a dimensionless group in fluid mechanics, which occurs in the study of flow in curved pipes and channels. It is named after the British scientist W. R. Dean, who was the first to provide a theoretical solution of the fluid
motion through curved pipes for laminar flow by using a perturbation procedure from a Poiseuille flow in a straight pipe to a flow in a pipe with very small curvature.
Physical Context
If a fluid is moving along a straight pipe that after some point becomes curved, the centripetal forces at the bend will cause the fluid particles to change their main direction of motion. There will be an adverse pressure gradient generated from the curvature with an increase in pressure, therefore a decrease in velocity close to the convex wall, and the contrary will occur towards the outer side of the pipe. This gives rise to a secondary motion superposed on the primary flow, with the fluid in the centre of the pipe being swept towards the outer side of the bend and the fluid near the pipe wall will return towards the inside of the bend. This secondary motion is expected to appear as a pair of counter-rotating cells, which are called Dean vortices.
Definition
The Dean number is typically denoted by De (or Dn). For a flow in a pipe or tube it is defined as:
where
is the density of the fluid
is the dynamic viscosity
is the axial velocity scale
is the diameter (for non-circular geometry, an equivalent diameter is used; see Reynolds number |

https://en.wikipedia.org/wiki/Gobuntu | Gobuntu was a short-lived official derivative of the Ubuntu operating system that was conceived to provide a distribution consisting entirely of free software. It was first released in October 2007.
Because Ubuntu now incorporates a "free software only" installer option, the Gobuntu project was rendered redundant in early 2008. As a result, Canonical made the decision officially to end the Gobuntu project with version 8.04.
In March 2009, it was announced that "Gobuntu 8.04.1 is the final release of Gobuntu. The project has merged back to mainline Ubuntu, so there is no need for a separate distribution".
History and development
Mark Shuttleworth first mentioned the idea of creating an Ubuntu derivative named Gnubuntu consisting entirely of free software, on 24 November 2005. Due to Richard Stallman's disapproval of the name, the project was later renamed Ubuntu-libre. Stallman had previously endorsed a distribution based on Ubuntu called gNewSense, and has criticized Ubuntu for using proprietary and non-free software in successive distributions, most notably, Ubuntu 7.04.
While introducing Ubuntu 7.10, Mark Shuttleworth said that it would
Gobuntu was officially announced by Mark Shuttleworth on 10 July 2007 and daily builds of Gobuntu 7.10 began to be publicly released.

https://en.wikipedia.org/wiki/Gibbons%E2%80%93Hawking%20effect | In the theory of general relativity, the Gibbons–Hawking effect is the statement that a temperature can be associated to each solution of the Einstein field equations that contains a causal horizon. It is named after Gary Gibbons and Stephen Hawking.
The term "causal horizon" does not necessarily refer to event horizons only, but could also stand for the horizon of the visible universe, for instance.
For example, Schwarzschild spacetime contains an event horizon and so can be associated a temperature. In the case of Schwarzschild spacetime this is the temperature of a black hole of mass , satisfying (see also Hawking radiation).
A second example is de Sitter space which contains an event horizon. In this case the temperature is proportional to the Hubble parameter , i.e. .

https://en.wikipedia.org/wiki/Taylor%20dispersion | Taylor dispersion or Taylor diffusion is an effect in fluid mechanics in which a shear flow can increase the effective diffusivity of a species. Essentially, the shear acts to smear out the concentration distribution in the direction of the flow, enhancing the rate at which it spreads in that direction. The effect is named after the British fluid dynamicist G. I. Taylor, who described the shear-induced dispersion for large Peclet numbers. The analysis was later generalized by Rutherford Aris for arbitrary values of the Peclet number. The dispersion process is sometimes also referred to as the Taylor-Aris dispersion.
The canonical example is that of a simple diffusing species in uniform
Poiseuille flow through a uniform circular pipe with no-flux
boundary conditions.
Description
We use z as an axial coordinate and r as the radial
coordinate, and assume axisymmetry. The pipe has radius a, and
the fluid velocity is:
The concentration of the diffusing species is denoted c and its
diffusivity is D. The concentration is assumed to be governed by
the linear advection–diffusion equation:
The concentration and velocity are written as the sum of a cross-sectional average (indicated by an overbar) and a deviation (indicated by a prime), thus:
Under some assumptions (see below), it is possible to derive an equation just involving the average quantities:

https://en.wikipedia.org/wiki/William%20Reginald%20Dean | William Reginald Dean (1896–1973) was a British applied mathematician and fluid dynamicist. His research interests included Stokes flow, solid mechanics, and flow in curved channels. The Dean number bears his name.
Dean carried out pioneering work in the study of fluid flow at low Reynolds numbers, by applying methods from elasticity theory. Some of his more famous results include solutions for secondary flow in curved tubes, for the perturbation to shear flow near a wall caused by a gap in the wall, and for flow in a corner.
Dean was an undergraduate at Trinity College, Cambridge. He spent five years at Imperial College, and was later a fellow of Trinity College. During the war he undertook mathematical work as part of the Anti-Aircraft Experimental Section of M.I.D. He also held the Goldsmid Chair in Applied Mathematics at University College London (from which he retired in 1964), and a chair at the University of Arizona.

https://en.wikipedia.org/wiki/Mitotic%20inhibitor | A mitotic inhibitor, microtubule inhibitor, or tubulin inhibitor, is a drug that inhibits mitosis, or cell division, and is used in treating cancer, gout, and nail fungus. These drugs disrupt microtubules, which are structures that pull the chromosomes apart when a cell divides. Mitotic inhibitors are used in cancer treatment, because cancer cells are able to grow through continuous division that eventually spread through the body (metastasize). Thus, cancer cells are more sensitive to inhibition of mitosis than normal cells. Mitotic inhibitors are also used in cytogenetics (the study of chromosomes), where they stop cell division at a stage where chromosomes can be easily examined.
Mitotic inhibitors are derived from natural substances such as plant alkaloids, and prevent cells from undergoing mitosis by disrupting microtubule polymerization, thus preventing cancerous growth. Microtubules are long, ropelike proteins that extend through the cell and move cellular components around. Microtubules are long polymers made of smaller units (monomers) of the protein tubulin. Microtubules are created during normal cell functions by assembling (polymerizing) tubulin components, and are disassembled when they are no longer needed. One of the important functions of microtubules is to move and separate chromosomes and other components of the cell for cell division (mitosis). Mitotic inhibitors interfere with the assembly and disassembly of tubulin into microtubule polymers. This interr |

https://en.wikipedia.org/wiki/DNMT3B | DNA (cytosine-5)-methyltransferase 3 beta, is an enzyme that in humans in encoded by the DNMT3B gene. Mutation in this gene are associated with immunodeficiency, centromere instability and facial anomalies syndrome.
Function
CpG methylation is an epigenetic modification that is important for embryonic development, imprinting, and X-chromosome inactivation. Studies in mice have demonstrated that DNA methylation is required for mammalian development. This gene encodes a DNA methyltransferase which is thought to function in de novo methylation, rather than maintenance methylation. The protein localizes primarily to the nucleus and its expression is developmentally regulated. Eight alternatively spliced transcript variants have been described. The full length sequences of variants 4 and 5 have not been determined.
Clinical significance
Immunodeficiency-centromeric instability-facial anomalies (ICF) syndrome is a result of defects in lymphocyte maturation resulting from aberrant DNA methylation caused by mutations in the DNMT3B gene.
Variants of the gene can also contribute to nicotine dependency.
Interactions
DNMT3B has been shown to interact with:
CBX5,
DNMT1,
DNMT3A,
KIF4A,
NCAPG,
SMC2,
SUMO1 and
UBE2I.

https://en.wikipedia.org/wiki/British%20Rail%20Class%2093%20%28InterCity%20250%29 | British Rail Class 93 is the traction classification assigned to the electric locomotives that were to enter service as part of British Rail (BR)'s InterCity 250 project on the West Coast Main Line (WCML). They would have been capable of travelling at up to , and powering a push-pull train of up to nine Mark 5 coaches and a driving van trailer (DVT), similar to the InterCity 225 sets.
The locomotives would have been derived from the Class 91 locomotives that entered service on the East Coast Main Line in 1989, and would thus have traced a lineage back to the Advanced Passenger Train (APT) that was planned to run on the WCML more than a decade earlier.
Tenders to construct the locomotives and rolling stock were issued in March 1991, with an expected in service date of 1995; it was envisaged that up to 30 complete trains would be initially required, with a total cost estimated at £380 million. However, the cancellation of the InterCity 250 project in July 1992 meant that the rolling stock orders were never made.
Speed and aerodynamic properties
The sleek, aerodynamic properties of the Class 93 would have allowed maximum speeds of up to . The maximum speed however would initially have been because of signalling and track alignment limitations.

https://en.wikipedia.org/wiki/Galaxy%20Zoo | Galaxy Zoo is a crowdsourced astronomy project which invites people to assist in the morphological classification of large numbers of galaxies. It is an example of citizen science as it enlists the help of members of the public to help in scientific research.
There have been 15 versions as of July 2017. Galaxy Zoo is part of the Zooniverse, a group of citizen science projects. An outcome of the project is to better determine the different aspects of objects and to separate them into classifications.
Origins
A key factor leading to the creation of the project was the problem of what has been referred to as data deluge, where research produces vast sets of information to the extent that research teams are not able to analyse and process much of it. Kevin Schawinski, previously an astrophysicist at Oxford University and co-founder of Galaxy Zoo, described the problem that led to Galaxy Zoo's creation when he was set the task of classifying the morphology of more than 900,000 galaxies by eye that had been imaged by the Sloan Digital Sky Survey at the Apache Point Observatory in New Mexico, USA. "I classified 50,000 galaxies myself in a week, it was mind-numbing." Chris Lintott, a co-founder of the project and a professor of astrophysics at the University of Oxford, stated: "In many parts of science, we're not constrained by what data we can get, we're constrained by what we can do with the data we have. Citizen science is a very powerful way of solving that problem."

https://en.wikipedia.org/wiki/Mixed-function%20oxidase | Mixed-function oxidase is the name of a family of oxidase enzymes that catalyze a reaction in which each of the two atoms of oxygen in O2 is used for a different function in the reaction.
Oxidase is a general name for enzymes that catalyze oxidations in which molecular oxygen is the electron acceptor but oxygen atoms do not appear in the oxidized product. Often, oxygen is reduced to either water (cytochrome oxidase of the mitochondrial electron transfer chain) or hydrogen peroxide (dehydrogenation of fatty acyl-CoA in peroxisomes). Most of the oxidases are flavoproteins.
The name "mixed-function oxidase" indicates that the enzyme oxidizes two different substrate simultaneously. Desaturation of fatty acyl-CoA in vertebrates is an example of the mixed-function oxidase reaction. In the process, saturated fatty acyl-CoA and NADPH are oxidized by molecular oxygen (O2) to produce monounsaturated fatty acyl-CoA, NADP+ and 2 molecules of water.
Reaction
The mixed-function oxidase reaction proceeds as follows:
AH + BH2 + O2 --> AOH + B + H2O (H2O as catalyst.)
Medical significance
High levels of mixed-function oxidase activity has been studied for their activation effects in human colon carcinoma cell lines, to study the susceptibility to certain cancers. The research has been successful in mice but remains inconclusive in humans.

https://en.wikipedia.org/wiki/Human%20Factors%20Analysis%20and%20Classification%20System | The Human Factors Analysis and Classification System (HFACS) identifies the human causes of an accident and offers tools for analysis as a way to plan preventive training. It was developed by Dr Scott Shappell of the Civil Aviation Medical Institute and Dr Doug Wiegmann of the University of Illinois at Urbana-Campaign in response to a trend that showed some form of human error was a primary causal factor in 80% of all flight accidents in the Navy and Marine Corps.
HFACS is based in the "Swiss Cheese" model of human error which looks at four levels of human failure, including unsafe acts, preconditions for unsafe acts, unsafe supervision, and organizational influences. It is a comprehensive human error framework, that folded James Reason's ideas into the applied setting, defining 19 causal categories within four levels of human failure.

https://en.wikipedia.org/wiki/Anticalin | Anticalin proteins are artificial proteins that are able to bind to antigens, either to proteins or to small molecules. They are not structurally related to antibodies, which makes them a type of antibody mimetic. Instead, they are derived from human lipocalins which are a family of naturally binding proteins. Anticalin proteins are being used in lieu of monoclonal antibodies, but are about eight times smaller with a size of about 180 amino acids and a mass of about 20 kDa.
The Anticalin technology is exclusively commercialized by Pieris Pharmaceuticals in Freising, Germany. Anticalin is a registered trademark of Pieris.
Properties
Anticalin proteins have better tissue penetration than antibodies and are stable at temperatures up to 70 °C. Unlike antibodies, they can be produced in bacterial cells like E. coli in large amounts.
While antibodies can only be directed at macromolecules such as proteins and at small molecules (haptens) only if bound to macromolecules, Anticalin proteins are able to selectively bind to small molecules as well.
They were mainly developed at the Technical University of Munich and are currently used as research tools. Diagnostic and therapeutic applications, including the use for targeted drug delivery, are being aimed at. The underlying technology was nominated for the German Future Prize in 2004.
Structure
Characteristic for Anticalin proteins is their barrel structure formed by eight antiparallel β-strands pairwise connected by loops and an |

https://en.wikipedia.org/wiki/Bounded%20deformation | In mathematics, a function of bounded deformation is a function whose distributional derivatives are not quite well-behaved-enough to qualify as functions of bounded variation, although the symmetric part of the derivative matrix does meet that condition. Thought of as deformations of elasto-plastic bodies, functions of bounded deformation play a major role in the mathematical study of materials, e.g. the Francfort-Marigo model of brittle crack evolution.
More precisely, given an open subset Ω of Rn, a function u : Ω → Rn is said to be of bounded deformation if the symmetrized gradient ε(u) of u,
is a bounded, symmetric n × n matrix-valued Radon measure. The collection of all functions of bounded deformation is denoted BD(Ω; Rn), or simply BD, introduced essentially by P.-M. Suquet in 1978. BD is a strictly larger space than the space BV of functions of bounded variation.
One can show that if u is of bounded deformation then the measure ε(u) can be decomposed into three parts: one absolutely continuous with respect to Lebesgue measure, denoted e(u) dx; a jump part, supported on a rectifiable (n − 1)-dimensional set Ju of points where u has two different approximate limits u+ and u−, together with a normal vector νu; and a "Cantor part", which vanishes on Borel sets of finite Hn−1-measure (where Hk denotes k-dimensional Hausdorff measure).
A function u is said to be of special bounded deformation if the Cantor part of ε(u) vanishes, so that the measure can be written as

https://en.wikipedia.org/wiki/Cylindrical%20algebraic%20decomposition | In mathematics, cylindrical algebraic decomposition (CAD) is a notion, and an algorithm to compute it, that are fundamental for computer algebra and real algebraic geometry. Given a set S of polynomials in Rn, a cylindrical algebraic decomposition is a decomposition of Rn into connected semialgebraic sets called cells, on which each polynomial has constant sign, either +, − or 0. To be cylindrical, this decomposition must satisfy the following condition: If 1 ≤ k < n and π is the projection from Rn onto Rn−k consisting in removing the last k coordinates, then for every pair of cells c and d, one has either π(c) = π(d) or π(c) ∩ π(d) = ∅. This implies that the images by π of the cells define a cylindrical decomposition of Rn−k.
The notion was introduced by George E. Collins in 1975, together with an algorithm for computing it.
Collins' algorithm has a computational complexity that is double exponential in n. This is an upper bound, which is reached on most entries. There are also examples for which the minimal number of cells is doubly exponential, showing that every general algorithm for cylindrical algebraic decomposition has a double exponential complexity.
CAD provides an effective version of quantifier elimination over the reals that has a much better computational complexity than that resulting from the original proof of Tarski–Seidenberg theorem. It is efficient enough to be implemented on a computer. It is one of the most important algorithms of computational real a |

https://en.wikipedia.org/wiki/Motor%20unit%20number%20estimation | Motor unit number estimation (MUNE) is a technique that uses electromyography to estimate the number of motor units in a muscle.
Principles
A motor unit consists of one alpha motor neuron and all the muscle fibres it innervates.
Muscles differ in the number of motor units that they contain, and how many muscle fibres are within each unit (innervation ratio). In a general sense, muscles that require specificity of movement, such as muscles in charge of eye movement, have fewer fibres per unit, while those that are meant for less specific tasks, such as the calf muscles in charge of jumping, have more.
MUNE uses a general formula of:
Number of motor units = compound muscle action potential size divided by the mean surface-detected motor unit action potential size
The compound muscle action potential (CMAP) size is found using supramaximal stimulation of the motor nerve to the muscle or muscle group (similar to a nerve conduction study). It is recorded using surface electrodes. This is representative of the sum of the surface detected motor unit action potentials from muscles innervated by that nerve.
Surface-detected motor unit action potential (SMUAP) size is the contribution of individual motor units. The way of finding the average size of these action potentials depends on the method used, as described below.
Methods
There are at least six techniques that are currently in use to estimate motor unit numbers. These include incremental stimulation, multi-point stimulatio |
https://en.wikipedia.org/wiki/Fusion%20mechanism | A fusion mechanism is any mechanism by which cell fusion or virus–cell fusion takes place, as well as the machinery that facilitates these processes. Cell fusion is the formation of a hybrid cell from two separate cells. There are three major actions taken in both virus–cell fusion and cell–cell fusion: the dehydration of polar head groups, the promotion of a hemifusion stalk, and the opening and expansion of pores between fusing cells. Virus–cell fusions occur during infections of several viruses that are health concerns relevant today. Some of these include HIV, Ebola, and influenza. For example, HIV infects by fusing with the membranes of immune system cells. In order for HIV to fuse with a cell, it must be able to bind to the receptors CD4, CCR5, and CXCR4. Cell fusion also occurs in a multitude of mammalian cells including gametes and myoblasts.
Viral mechanisms
Fusogens
Proteins that allow viral or cell membranes to overcome barriers to fusion are called fusogens. Fusogens involved in virus-to-cell fusion mechanisms were the first of these proteins to be discovered. Viral fusion proteins are necessary for membrane fusion to take place. There is evidence that ancestral species of mammals may have incorporated these same proteins into their own cells as a result of infection. For this reason, similar mechanisms and machinery are utilized in cell–cell fusion.
In response to certain stimuli, such as low pH or binding to cellular receptors, these fusogens will change c |
https://en.wikipedia.org/wiki/Induced%20pluripotent%20stem%20cell | Induced pluripotent stem cells (also known as iPS cells or iPSCs) are a type of pluripotent stem cell that can be generated directly from a somatic cell. The iPSC technology was pioneered by Shinya Yamanaka and Kazutoshi Takahashi in Kyoto, Japan, who together showed in 2006 that the introduction of four specific genes (named Myc, Oct3/4, Sox2 and Klf4), collectively known as Yamanaka factors, encoding transcription factors could convert somatic cells into pluripotent stem cells. Shinya Yamanaka was awarded the 2012 Nobel Prize along with Sir John Gurdon "for the discovery that mature cells can be reprogrammed to become pluripotent."
Pluripotent stem cells hold promise in the field of regenerative medicine. Because they can propagate indefinitely, as well as give rise to every other cell type in the body (such as neurons, heart, pancreatic, and liver cells), they represent a single source of cells that could be used to replace those lost to damage or disease.
The most well-known type of pluripotent stem cell is the embryonic stem cell. However, since the generation of embryonic stem cells involves destruction (or at least manipulation) of the pre-implantation stage embryo, there has been much controversy surrounding their use. Patient-matched embryonic stem cell lines can now be derived using somatic cell nuclear transfer (SCNT).
Since iPSCs can be derived directly from adult tissues, they not only bypass the need for embryos, but can be made in a patient-matched manner, w |

It works on the principle that equivalent sentences should roughly correspond in length—that is, longer sentences in one language should correspond to longer sentences in the other language. The algorithm was described in a 1993 paper by William A. Gale and Kenneth W. Church of AT&T Bell Laboratories.

https://en.wikipedia.org/wiki/Eduard%20Stiefel | Eduard L. Stiefel (21 April 1909 – 25 November 1978) was a Swiss mathematician. Together with Cornelius Lanczos and Magnus Hestenes, he invented the conjugate gradient method, and gave what is now understood to be a partial construction of the Stiefel–Whitney classes of a real vector bundle, thus co-founding the study of characteristic classes.
Biography
Stiefel entered the Swiss Federal Institute of Technology (ETH Zurich) in 1928. He received his Ph.D. in 1935 under Heinz Hopf; his dissertation was titled "Richtungsfelder und Fernparallelismus in n-dimensionalen Mannigfaltigkeiten". Stiefel completed his habilitation in 1942. Besides his academic pursuits, Stiefel was also active as a military officer, rising to the rank of colonel in the Swiss army during World War II.
Stiefel achieved his full professorship at ETH Zurich in 1943, founding the Institute for Applied Mathematics five years later. The objective of the new institute was to design and construct an electronic computer (the Elektronische Rechenmaschine der ETH, or ERMETH). He spent a year in the United States commencing in August, 1951. During this time, he met Magnus Hestenes and many other scientists at the National Bureau of Standards and these professional associations served him well during the remainder of his career at Zurich.

https://en.wikipedia.org/wiki/Decamethyldizincocene | Decamethyldizincocene is an organozinc compound with the formula [Zn2(η5–C5Me5)2]. It is the first and an unusual example of a compound with a Zn-Zn bond. Decamethyldizincocene is a colorless crystalline solid that burns spontaneously in the presence of oxygen and reacts with water. It is stable at room temperature and especially soluble in diethyl ether, benzene, pentane, or tetrahydrofuran.
Synthesis
The ability of metals to form heteronuclear or homonuclear metal-metal bonds varies throughout the periodic table. Among the group 12 elements, mercury readily forms [M-M]2+ units whereas the elements cadmium and zinc form fewer examples of such species. Decamethyldizincocene was reported in 2004 by Carmona and coworkers as an unexpected product of the reaction between decamethylzincocene (Zn(C5Me5)2) and diethylzinc (ZnEt2).
]
2 (η5-C5Me5)2Zn + Et2Zn → (η5-C5Me5)2Zn2 + 2 (η5-C5Me5)ZnEt + hydrocarbon(s)
The analogous reaction of zincocene (Zn(C5H5)2) with diethylzinc gives (η5-C5H5)ZnEt. Therefore, the stabilizing effect of the methyl groups on the cyclopentadienyl rings is of great importance in the formation of decamethydizincocene. The use of ZnEt2 as a reactant is of particular significance.
The organozinc precursor is important. Diphenylzinc (Zn(C6H5)2), despite its lower solubility, can be utilized in place of ZnEt2. On the other hand, ZnMe2 gives only the half-sandwich compound [(η5-C5Me5)ZnMe].
Both (η5-C5Me5)ZnEt and decamethyldizincocene are produced from the re |
https://en.wikipedia.org/wiki/Osmolyte | Osmolytes are low-molecular-weight organic compounds that influence the properties of biological fluids. Osmolytes are a class of organic molecules that play a significant role in regulating osmotic pressure and maintaining cellular homeostasis in various organisms, particularly in response to environmental stressors. Their primary role is to maintain the integrity of cells by affecting the viscosity, melting point, and ionic strength of the aqueous solution. When a cell swells due to external osmotic pressure, membrane channels open and allow efflux of osmolytes carrying water, restoring normal cell volume.
These molecules are involved in counteracting the effects of osmotic stress, which occurs when there are fluctuations in the concentration of solutes (such as ions and sugars) inside and outside cells. Osmolytes help cells adapt to changing osmotic conditions, thereby ensuring their survival and functionality. Osmolytes also interact with the constituents of the cell, e.g., they influence protein folding. Common osmolytes include amino acids, sugars and polyols, methylamines, methylsulfonium compounds, and urea.
Case studies
Natural osmolytes that can act as osmoprotectants include trimethylamine N-oxide (TMAO), dimethylsulfoniopropionate, sarcosine, betaine, glycerophosphorylcholine, myo-inositol, taurine, glycine, and others. Bacteria accumulate osmolytes for protection against a high osmotic environment. The osmolytes are neutral non-electrolytes, except in bacteria |
https://en.wikipedia.org/wiki/Syncoilin |
Discovery
Syncoilin is a muscle-specific atypical type III intermediate filament protein encoded in the human by the gene SYNC. It was first isolated as a binding partner to α-dystrobrevin, as determined by a yeast two-hybrid assay.
Later, a yeast two-hybrid method was used to demonstrate that syncoilin is a binding partner of desmin. These binding partners suggest that syncoilin acts as a mechanical "linker" between the sarcomere Z-disk (where desmin is localized) and the dystrophin-associated protein complex (where α-dystrobrevin is localized). However, the specific in vivo functions of syncoilin have not yet been determined.
Through the use of Western blotting techniques, a second species of syncoilin was found. This species was 55kDa in size, whereas the original species of syncoilin was 64kDa in size. This discovery inspired scientists to use gene splicing to identify two new isoforms called SYNC2 and SYNC3.
Abnormally high levels of syncoilin have been shown to be a characteristic of neuromuscular wasting diseases such as desminopathy and muscular dystrophy. Therefore, syncoilin is being explored as a promising marker of neuromuscular disease.
Structure
Syncoilin is characterized as an intermediate filament and contains the key structural features that make up intermediate filaments such as a head region, linker regions, alpha helices, and a tail region. Each protein that is classified as an intermediate filament will vary in the size and shape of their head an |

The polar equation of this curve is of the form
.
Devil's curves were discovered in 1750 by Gabriel Cramer, who studied them extensively.
The name comes from the shape its central lemniscate takes when graphed. The shape is named after the juggling game diabolo, which was named after the Devil and which involves two sticks, a string, and a spinning prop in the likeness of the lemniscate.
For , the central lemniscate, often called hourglass, is horizontal. For it is vertical. If , the shape becomes a circle.
The vertical hourglass intersects the y-axis at . The horizontal hourglass intersects the x-axis at .
Electric Motor Curve
A special case of the Devil's curve occurs at , where the curve is called the electric motor curve. It is defined by an equation of the form
.
The name of the special case comes from the middle shape's resemblance to the coils of wire, which rotate from forces exerted by magnets surrounding it.

https://en.wikipedia.org/wiki/Synemin | Synemin, also known as desmuslin, is a protein that in humans is encoded by the SYNM gene. Synemin is an intermediate filament (IF) family member. IF proteins are cytoskeletal proteins that confer resistance to mechanical stress and are encoded by a dispersed multigene family. This protein has been found to form a linkage between desmin, which is a subunit of the IF network, and the extracellular matrix, and provides an important structural support in muscle.
Function
Synemin is an intermediate filament (IF) and, like other IFs, primarily functions to integrate mechanical stress and maintain structural integrity in eukaryotic cells. While it has been observed in a variety of cell types, it has been best studied in the sarcomere of skeletal myocytes. It localizes at the Z-disk and has been shown to bind to α-dystrobrevin, α-actinin, and desmin to act as a mechanical linker in transmitting force laterally throughout the tissue, especially between the contractile myofibrils and extracellular matrix. Synemin contributes to linkage between costameres and the contractile apparatus in skeletal muscle of synemin null animals. Synemin plays an important regulatory role in the heart and the consequences of its absence are profound.
Properties
Synemin has properties very similar to the intermediate filament syncoilin. In particular, it binds to α-dystrobrevin in the dystrophin-associated protein complex to act as a mechanical "linker" between the myofibrillar network and the cell |

https://en.wikipedia.org/wiki/Holdridge%20life%20zones | The Holdridge life zones system is a global bioclimatic scheme for the classification of land areas. It was first published by Leslie Holdridge in 1947, and updated in 1967. It is a relatively simple system based on few empirical data, giving objective criteria. A basic assumption of the system is that both soil and the climax vegetation can be mapped once the climate is known.
Scheme
While it was first designed for tropical and subtropical areas, the system now applies globally. The system has been shown to fit not just tropical vegetation zones,but Mediterranean zones, and boreal zones too, but is less applicable to cold oceanic or cold arid climates where moisture becomes the predominant factor. The system has found a major use in assessing the potential changes in natural vegetation patterns due to global warming.
The three major axes of the barycentric subdivisions are:
precipitation (annual, logarithmic)
biotemperature (mean annual, logarithmic)
potential evapotranspiration ratio (PET) to mean total annual precipitation.
Further indicators incorporated into the system are:
humidity provinces
latitudinal regions
altitudinal belts
Biotemperature is based on the growing season length and temperature. It is measured as the mean of all annual temperatures, with all temperatures below freezing and above 30 °C adjusted to 0 °C, as most plants are dormant at these temperatures. Holdridge's system uses biotemperature first, rather than the temperate latitude bias of M |

https://en.wikipedia.org/wiki/Isomorphism%20extension%20theorem | In field theory, a branch of mathematics, the isomorphism extension theorem is an important theorem regarding the extension of a field isomorphism to a larger field.
Isomorphism extension theorem
The theorem states that given any field , an algebraic extension field of and an isomorphism mapping onto a field then can be extended to an isomorphism mapping onto an algebraic extension of (a subfield of the algebraic closure of ).
The proof of the isomorphism extension theorem depends on Zorn's lemma.
