https://en.wikipedia.org/wiki/Nuclear%20receptor%20coactivator%203
The nuclear receptor coactivator 3 also known as NCOA3 is a protein that, in humans, is encoded by the NCOA3 gene. NCOA3 is also frequently called 'amplified in breast 1' (AIB1), steroid receptor coactivator-3 (SRC-3), or thyroid hormone receptor activator molecule 1 (TRAM-1). Function NCOA3 is a transcriptional coactivator protein that contains several nuclear receptor interacting domains and an intrinsic histone acetyltransferase activity. NCOA3 is recruited to DNA promotion sites by ligand-activated nuclear receptors. NCOA3, in turn, acylates histones, which makes downstream DNA more accessible to transcription. Hence, NCOA3 assists nuclear receptors in the upregulation of gene expression. Clinical significance The ratio of PAX2 to AIB-1 protein expression may be predictive of the effectiveness of tamoxifen in breast cancer treatment. Several molecular mechanisms implicate NCOA3 (AIB1) in the endocrine therapy resistance (depicted in the figure). Signaling pathways or mutations (i.e. HER2/neu overexpression, activating mutations in PIK3CA (PI3K), activating mutations in the proto-oncogene tyrosine-protein kinase Src, etc.) that lead to persistent activation of ERK and/or PIK3CA/AKT kinase pathways result, in one hand in an enhanced AIB1 transcriptional coactivation capacity, and in the other hand in the inhibition of the proteasome-dependent AIB1 turn-over and therefore, in AIB1 overexpression. In both conditions, the equilibrium of estrogen receptor (ER) complex

The nuclear receptor co-repressor 1 also known as thyroid-hormone- and retinoic-acid-receptor-associated co-repressor 1 (TRAC-1) is a protein that in humans is encoded by the NCOR1 gene. NCOR1 is a transcriptional coregulatory protein which contains several nuclear receptor interacting domains. In addition, NCOR1 appears to recruit histone deacetylases to DNA promoter regions. Hence NCOR1 assists nuclear receptors in the down regulation of gene expression. Loss of function of this protein significantly increases the strength and power of mouse muscles. Family It is a member of the family of nuclear receptor corepressors; the other human protein that is a member of that family is Nuclear receptor co-repressor 2. Interactions Nuclear receptor co-repressor 1 has been shown to interact with: Androgen receptor, CHD1, Calcitriol receptor GPS2, Glucocorticoid receptor, HDAC3, HDAC4, HDAC7A, HDAC9, HEY2, Histone deacetylase 5, MAP3K7IP2, MECP2, Peroxisome proliferator-activated receptor alpha, Peroxisome proliferator-activated receptor gamma Promyelocytic leukemia protein, RUNX1T1, Retinoic acid receptor alpha, Retinoic acid receptor gamma, SAP30, TBL1XR1, TBL1X, and ZBTB33.

The nuclear receptor co-repressor 2 () is a transcriptional coregulatory protein that contains several nuclear receptor-interacting domains. In addition, NCOR2 appears to recruit histone deacetylases to DNA promoter regions. Hence NCOR2 assists nuclear receptors in the down regulation of target gene expression. NCOR2 is also referred to as a silencing mediator for retinoid or thyroid-hormone receptors (SMRT) or T3 receptor-associating cofactor 1 (TRAC-1). Function NCOR2/SMRT is a transcriptional coregulatory protein that contains several modulatory functional domains including multiple autonomous repression domains as well as two or three C-terminal nuclear receptor-interacting domains. NCOR2/SMRT serves as a repressive coregulatory factor (corepressor) for multiple transcription factor pathways. In this regard, NCOR2/SMRT functions as a platform protein, facilitating the recruitment of histone deacetylases to the DNA promoters bound by its interacting transcription factors. Family It is a member of the family of nuclear receptor corepressors; the other human protein that is a member of that family is Nuclear receptor co-repressor 1. Discovery SMRT was initially cloned and characterized in the laboratory of Dr. Ronald M. Evans at the Salk Institute for Biological Studies. In another early investigation into this molecule, similar findings were reported in a variant referred to as TRAC-1. Interactions Nuclear receptor co-repressor 2 has been shown to interact with
https://en.wikipedia.org/wiki/Corepressor
In genetics and molecular biology, a corepressor is a molecule that represses the expression of genes. In prokaryotes, corepressors are small molecules whereas in eukaryotes, corepressors are proteins. A corepressor does not directly bind to DNA, but instead indirectly regulates gene expression by binding to repressors. A corepressor downregulates (or represses) the expression of genes by binding to and activating a repressor transcription factor. The repressor in turn binds to a gene's operator sequence (segment of DNA to which a transcription factor binds to regulate gene expression), thereby blocking transcription of that gene. Function Prokaryotes In prokaryotes, the term corepressor is used to denote the activating ligand of a repressor protein. For example, the E. coli tryptophan repressor (TrpR) is only able to bind to DNA and repress transcription of the trp operon when its corepressor tryptophan is bound to it. TrpR in the absence of tryptophan is known as an aporepressor and is inactive in repressing gene transcription. Trp operon encodes enzymes responsible for the synthesis of tryptophan. Hence TrpR provides a negative feedback mechanism that regulates the biosynthesis of tryptophan. In short tryptophan acts as a corepressor for its own biosynthesis. Eukaryotes In eukaryotes, a corepressor is a protein that binds to transcription factors. In the absence of corepressors and in the presence of coactivators, transcription factors upregulate gene express
https://en.wikipedia.org/wiki/STAT6
Signal transducer and activator of transcription 6 (STAT6) is a transcription factor that belongs to the Signal Transducer and Activator of Transcription (STAT) family of proteins. The proteins of STAT family transmit signals from a receptor complex to the nucleus and activate gene expression. Similarly as other STAT family proteins, STAT6 is also activated by growth factors and cytokines. STAT6 is mainly activated by cytokines interleukin-4 and interleukin-13. Molecular biology In the human genome, STAT6 protein is encoded by the STAT6 gene, located on the chromosome 12q13.3-q14.1. The gene encompasses over 19 kb and consists of 23 exons. STAT6 shares structural similarity with the other STAT proteins and is composed of the N-terminal domain, DNA binding domain, SH3- like domain, SH2 domain and transactivation domain (TAD). STAT proteins are activated by the Janus family (JAKs) tyrosine kinases in response to cytokine exposure. STAT6 is activated by cytokines interleukin-4 (IL-4), and interleukin-13 (IL-13) with their receptors that both contain the α subunit of the IL-4 receptor (IL-4Rα). Tyrosine phosporylation of STAT6 after stimulation by IL-4 results in the formation of STAT6 homodimers that bind specific DNA elements via a DNA-binding domain. Function STAT6-mediated signaling pathway is required for the development of T-helper type 2 (Th2) cells and Th2 immune response. Expression of Th2 cytokines, including IL-4, IL-13, and IL-5, was reduced in STAT6-deficient m
https://en.wikipedia.org/wiki/STAT4
Signal transducer and activator of transcription 4 (STAT4) is a transcription factor belonging to the STAT protein family, composed of STAT1, STAT2, STAT3, STAT4, STAT5A, STAT5B, STAT6. STAT proteins are key activators of gene transcription which bind to DNA in response to cytokine gradient. STAT proteins are a common part of Janus kinase (JAK)- signalling pathways, activated by cytokines.STAT4 is required for the development of Th1 cells from naive CD4+ T cells and IFN-γ production in response to IL-12. There are two known STAT4 transcripts, STAT4α and STAT4β, differing in the levels of interferon-gamma (IFN-γ )production downstream. Structure Human as well murine STAT4 genes lie next to STAT1 gene locus suggesting that the genes arose by gene duplication. STAT proteins have six functional domains: 1. N-terminal interaction domain – crucial for dimerization of inactive STATs and nuclear translocation; 2.helical coiled coil domain –  association with regulatory factors; 3. central DNA-binding domain – binding to the enhancer region of IFN-γ activated sequence (GAS) family genes; 4. linker domain –  assisting during the DNA binding process; 5. Src homology 2 (SH2) domain – critical for specific binding to the cytokine receptor after tyrosine phosphorylation; 6. C-terminal transactivation domain – triggering the transcriptional process. The length of the protein is 748 amino acids, and the molecular weight is 85 941 Dalton. Expression Distribution of STAT4 is restricted
https://en.wikipedia.org/wiki/STAT2
Signal transducer and activator of transcription 2 is a protein that in humans is encoded by the STAT2 gene. It is a member of the STAT protein family. This protein is critical to the biological response of type I interferons (IFNs). STAT2 sequence identity between mouse and human is only 68%. Function The protein encoded by this gene is a member of the STAT protein family. In response to cytokines and growth factors, STAT family members are phosphorylated by the receptor associated kinases, and then form homo- or heterodimers that translocate to the cell nucleus where they act as transcription activators. In response to IFN, this protein forms a complex with STAT1 and IFN regulatory factor family protein p48 (IRF9) and form ISGF-3 (IFN-stimulated gene factor-3), in which this protein acts as a transactivator, but lacks the ability to bind DNA directly. ISGF-3 proceeds the activation of genes via the IFN-stimulated response element (ISRE). ISRE-driven genes include Ly-6C, the double-stranded RNA kinase (PKR), 2´ to 5´ oligoadenylate synthase (OAS), MX and potentially MHC class I. Transcription adaptor P300/CBP (EP300/CREBBP) has been shown to interact specifically with this protein, which is thought to be involved in the process of blocking IFN-alpha response by adenovirus. STAT2 knockout mice are unresponsive to type I IFN and extremely vulnerable to viral infection. They indicate the loss of the type I IFN autocrine loop and several defects in macrophages and T cell res

https://en.wikipedia.org/wiki/Cartan%E2%80%93Hadamard%20theorem
In mathematics, the Cartan–Hadamard theorem is a statement in Riemannian geometry concerning the structure of complete Riemannian manifolds of non-positive sectional curvature. The theorem states that the universal cover of such a manifold is diffeomorphic to a Euclidean space via the exponential map at any point. It was first proved by Hans Carl Friedrich von Mangoldt for surfaces in 1881, and independently by Jacques Hadamard in 1898. Élie Cartan generalized the theorem to Riemannian manifolds in 1928 (; ; ). The theorem was further generalized to a wide class of metric spaces by Mikhail Gromov in 1987; detailed proofs were published by for metric spaces of non-positive curvature and by for general locally convex metric spaces. Riemannian geometry The Cartan–Hadamard theorem in conventional Riemannian geometry asserts that the universal covering space of a connected complete Riemannian manifold of non-positive sectional curvature is diffeomorphic to Rn. In fact, for complete manifolds of non-positive curvature, the exponential map based at any point of the manifold is a covering map. The theorem holds also for Hilbert manifolds in the sense that the exponential map of a non-positively curved geodesically complete connected manifold is a covering map (; ). Completeness here is understood in the sense that the exponential map is defined on the whole tangent space of a point. Metric geometry In metric geometry, the Cartan–Hadamard theorem is the statement that the uni
https://en.wikipedia.org/wiki/Ligase%20ribozyme
The RNA Ligase ribozyme was the first of several types of synthetic ribozymes produced by in vitro evolution and selection techniques. They are an important class of ribozymes because they catalyze the assembly of RNA fragments into phosphodiester RNA polymers, a reaction required of all extant nucleic acid polymerases and thought to be required for any self-replicating molecule. Ideas that the origin of life may have involved the first self-replicating molecules being ribozymes are called RNA World hypotheses. Ligase ribozymes may have been part of such a pre-biotic RNA world. In order to copy RNA, fragments or monomers (individual building blocks) that have 5′-triphosphates must be ligated together. This is true for modern (protein-based) polymerases, and is also the most likely mechanism by which a ribozyme self-replicase in an RNA world might function. Yet no one has found a natural ribozyme that can perform this reaction. In vitro evolution and selection RNA in vitro evolution or SELEX enables the artificial evolution and selection of RNA molecules that possess a desired property, such as binding affinity for a particular ligand or an activity such as that of an enzyme or catalyst. The first such selections involved isolation of various aptamers that bind to small molecules. The first catalytic RNAs produced by in vitro evolution were RNA ligases, catalytic RNAs that join two RNA fragments to produce a single adduct. The most active ligase known to date is the Class I
https://en.wikipedia.org/wiki/Hiberna
Hiberna in the Polish–Lithuanian Commonwealth, also known as "chleb zimowy" (winter bread), was an obligation to guarantee accommodation for troops during winter time. It was an obligation of Królewszczyzna (crown lands) and church estates. Initially it was paid in kind, in 1649-1652 it was a targeted tax to support the troops collected by Grand Crown Hetman. Over time hiberna absorbed some other taxes (e.g. Jewish poll tax and kwarta) and extended to other population categories. The term is borrowed from ancient Rome, where the castra hiberna were a winter camps for Roman legions.

https://en.wikipedia.org/wiki/Genetically%20modified%20plant
Genetically modified plants have been engineered for scientific research, to create new colours in plants, deliver vaccines, and to create enhanced crops. Plant genomes can be engineered by physical methods or by use of Agrobacterium for the delivery of sequences hosted in T-DNA binary vectors. Many plant cells are pluripotent, meaning that a single cell from a mature plant can be harvested and then under the right conditions form a new plant. This ability is most often taken advantage by genetic engineers through selecting cells that can successfully be transformed into an adult plant which can then be grown into multiple new plants containing transgene in every cell through a process known as tissue culture. Research Much of the advances in the field genetic engineering has come from experimentation with tobacco. Major advances in tissue culture and plant cellular mechanisms for a wide range of plants has originated from systems developed in tobacco. It was the first plant to be genetically engineered and is considered a model organism for not only genetic engineering, but a range of other fields. As such the transgenic tools and procedures are well established making it one of the easiest plants to transform. Another major model organism relevant to genetic engineering is Arabidopsis thaliana. Its small genome and short life cycle makes it easy to manipulate and it contains many homologs to important crop species. It was the first plant sequenced, has abundant bioinform

In probability theory, the telegraph process is a memoryless continuous-time stochastic process that shows two distinct values. It models burst noise (also called popcorn noise or random telegraph signal). If the two possible values that a random variable can take are and , then the process can be described by the following master equations: and where is the transition rate for going from state to state and is the transition rate for going from going from state to state . The process is also known under the names Kac process (after mathematician Mark Kac), and dichotomous random process. Solution The master equation is compactly written in a matrix form by introducing a vector , where is the transition rate matrix. The formal solution is constructed from the initial condition (that defines that at , the state is ) by . It can be shown that where is the identity matrix and is the average transition rate. As , the solution approaches a stationary distribution given by Properties Knowledge of an initial state decays exponentially.

https://en.wikipedia.org/wiki/Cascade%20algorithm
In the mathematical topic of wavelet theory, the cascade algorithm is a numerical method for calculating function values of the basic scaling and wavelet functions of a discrete wavelet transform using an iterative algorithm. It starts from values on a coarse sequence of sampling points and produces values for successively more densely spaced sequences of sampling points. Because it applies the same operation over and over to the output of the previous application, it is known as the cascade algorithm. Successive approximation The iterative algorithm generates successive approximations to ψ(t) or φ(t) from {h} and {g} filter coefficients. If the algorithm converges to a fixed point, then that fixed point is the basic scaling function or wavelet. The iterations are defined by For the kth iteration, where an initial φ(0)(t) must be given. The frequency domain estimates of the basic scaling function is given by and the limit can be viewed as an infinite product in the form If such a limit exists, the spectrum of the scaling function is The limit does not depends on the initial shape assume for φ(0)(t). This algorithm converges reliably to φ(t), even if it is discontinuous. From this scaling function, the wavelet can be generated from Successive approximation can also be derived in the frequency domain. References C.S. Burrus, R.A. Gopinath, H.

https://en.wikipedia.org/wiki/2%CF%80%20theorem
In mathematics, the theorem of Gromov and Thurston states a sufficient condition for Dehn filling on a cusped hyperbolic 3-manifold to result in a negatively curved 3-manifold. Let be a cusped hyperbolic 3-manifold. Disjoint horoball neighborhoods of each cusp can be selected. The boundaries of these neighborhoods are quotients of horospheres and thus have Euclidean metrics. A slope, i.e. unoriented isotopy class of simple closed curves on these boundaries, thus has a well-defined length by taking the minimal Euclidean length over all curves in the isotopy class. The theorem states: a Dehn filling of with each filling slope greater than results in a 3-manifold with a complete metric of negative sectional curvature. In fact, this metric can be selected to be identical to the original hyperbolic metric outside the horoball neighborhoods. The basic idea of the proof is to explicitly construct a negatively curved metric inside each horoball neighborhood that matches the metric near the horospherical boundary. This construction, using cylindrical coordinates, works when the filling slope is greater than . See for complete details. According to the geometrization conjecture, these negatively curved 3-manifolds must actually admit a complete hyperbolic metric. A horoball packing argument due to Thurston shows that there are at most 48 slopes to avoid on each cusp to get a hyperbolic 3-manifold. For one-cusped hyperbolic 3-manifolds, an improvement due to Colin A
https://en.wikipedia.org/wiki/Radial%20turbine
A radial turbine is a turbine in which the flow of the working fluid is radial to the shaft. The difference between axial and radial turbines consists in the way the fluid flows through the components (compressor and turbine). Whereas for an axial turbine the rotor is 'impacted' by the fluid flow, for a radial turbine, the flow is smoothly orientated perpendicular to the rotation axis, and it drives the turbine in the same way water drives a watermill. The result is less mechanical stress (and less thermal stress, in case of hot working fluids) which enables a radial turbine to be simpler, more robust, and more efficient (in a similar power range) when compared to axial turbines. When it comes to high power ranges (above 5 MW) the radial turbine is no longer competitive (due to its heavy and expensive rotor) and the efficiency becomes similar to that of the axial turbines. Advantages and challenges Compared to an axial flow turbine, a radial turbine can employ a relatively higher pressure ratio (≈4) per stage with lower flow rates. Thus these machines fall in the lower specific speed and power ranges. For high temperature applications rotor blade cooling in radial stages is not as easy as in axial turbine stages. Variable angle nozzle blades can give higher stage efficiencies in a radial turbine stage even at off-design point operation. In the family of water turbines, the Francis turbine is a very well-known IFR turbine which generates much greater power with a relatively l

ORYX is an encryption algorithm used in cellular communications in order to protect data traffic. It is a stream cipher designed to have a very strong 96-bit key strength with a way to reduce the strength to 32-bits for export. However, due to mistakes the actual strength is a trivial 16-bits and any signal can be cracked after the first 25–27 bytes. It is one of the four cryptographic primitives standardized by TIA's for use in their digital cellular communications standards TDMA and CDMA. Algorithm description ORYX is a simple stream cipher based on binary linear-feedback shift registers (LFSRs) to protect cellular data transmissions (for wireless data services). The cipher ORYX has four components: three 32-bit LFSRs which labeled as LFSRA, LFSRB and LFSRK, and an S-box containing a known permutation P of the integer values 0 to 255. The feedback function for LFSRK is defined as: Lt + 32 = Lt + 28 ⊕ Lt + 19 ⊕ Lt + 18 ⊕ Lt + 16 ⊕ Lt + 14 ⊕ Lt + 11 ⊕ Lt + 10 ⊕ Lt + 9 ⊕ Lt + 6 ⊕ Lt + 5 ⊕ Lt + 1 ⊕ Lt The feedback functions for LFSRA are defined as: Lt + 32 = Lt + 26 ⊕ Lt + 23 ⊕ Lt + 22 ⊕ Lt + 16 ⊕ Lt + 12 ⊕ Lt + 11 ⊕ Lt + 10 ⊕ Lt + 8 ⊕ Lt + 7 ⊕ Lt + 5 ⊕ Lt + 4 ⊕ Lt + 2 ⊕ Lt + 1 ⊕ Lt and Lt + 32 = Lt + 27 ⊕ Lt + 26 ⊕ Lt + 25 ⊕ Lt + 24 ⊕ Lt + 23 ⊕ Lt + 22 ⊕ Lt + 17 ⊕ Lt + 13 ⊕ Lt + 11 ⊕ Lt + 10 ⊕ Lt + 9 ⊕ Lt + 8 ⊕ Lt + 7 ⊕ Lt + 2 ⊕ Lt + 1 ⊕ Lt The feedback function for LFSRB is: Lt + 32 = Lt + 31 ⊕ Lt + 21 ⊕ Lt + 20 ⊕ Lt + 16 ⊕ Lt + 15 ⊕ Lt + 6 ⊕ Lt + 3 ⊕ Lt + 1 ⊕ Lt Se

Store-operated channels (SOCs) are ion channels located in the plasma membrane of cells. These channels are most studied in regard to their role in calcium entry into the cytoplasm from extracellular milieu. There are other SOC channels selective to other ions. Calcium SOCs are especially important for the cell because they are the major source of intracellular calcium; and calcium itself is involved in a wide array of vital cellular functions. SOCs are so called because they are activated by intracellular calcium (particularly the endoplasmic reticulum (ER)) stores depletion by both physiological or pharmacological processes.

https://en.wikipedia.org/wiki/Mpack%2C%20Senegal
Mpack (also spelt Mpak) is a village in Niaguis Arrondissement, Ziguinchor Department, Ziguinchor Region in southern Senegal. Government statistics classified it as a rural community and recorded its population as 518 people in 72 households. It is located about seven kilometres from the regional capital of Ziguinchor. It is one of the endpoints of the 90-km long Oussouye-Kabrousse-Cap Skirring-Ziguinchor-Mpack road, which is being rebuilt with 17 billion CFA francs of funding from the European Union. The village used to be on the front lines of the Casamance Conflict between the Senegalese government and the Movement of Democratic Forces of Casamance. The town contains the only border checkpoint between Senegal and Guinea-Bissau with an asphalt road; its counterpart on the Guinea-Bissau side is Sao Domingos. During the 1998 Guinea-Bissau Civil War, up to 100 refugees an hour passed through the checkpoint and the village as they fled the fighting. Later, as the Casamance Conflict intensified, the checkpoint was frequently closed, as MDFC members were believed to be taking refuge in Guinea-Bissau. The area was also heavily mined during the fighting; local NGOs made efforts to clear the mines in 2002 and 2003, rehabilitating over 100 houses in the village and its surrounding area, following which the Senegalese military declared the area safe; however, casualties due to exploding mines continued to occur in 2004. A camp was set up in the Bourgadié neighbourhood there in March
https://en.wikipedia.org/wiki/Grown-junction%20transistor
The grown-junction transistor was the first type of bipolar junction transistor made. It was invented by William Shockley at Bell Labs on June 23, 1948 (patent filed June 26, 1948), six months after the first bipolar point-contact transistor. The first germanium prototypes were made in 1949. Bell Labs announced Shockley’s grown-junction transistor on July 4, 1951. An NPN grown-junction transistor is made of a single crystal of semiconductor material which has two PN junctions grown into it. During the growth process, a seed crystal is slowly pulled from a bath of molten semiconductor, which then grows into a rod-shaped crystal (boule). The molten semiconductor is doped N-type at the start. At a predetermined moment in the growth process a small pellet of a P-type dopant is added, almost immediately followed by a somewhat larger pellet of an N-type dopant. These dopants dissolve in the molten semiconductor changing the type of semiconductor subsequently grown. The resulting crystal has a thin layer of P-type material sandwiched between sections of N-type material. This P-type layer may be as little as a thousandth of an inch (25 μm) thick. The crystal is sliced, leaving the thin P-type layer in the center of the slice, then cut into bars. Each bar is made into a transistor by soldering its N-type ends to supporting and conducting leads, then welding a very fine gold lead to the central P-type layer, and finally encasing in a hermetically sealed can. A similar process, using t

The Blaschke selection theorem is a result in topology and convex geometry about sequences of convex sets. Specifically, given a sequence of convex sets contained in a bounded set, the theorem guarantees the existence of a subsequence and a convex set such that converges to in the Hausdorff metric. The theorem is named for Wilhelm Blaschke. Alternate statements A succinct statement of the theorem is that the metric space of convex bodies is locally compact. Using the Hausdorff metric on sets, every infinite collection of compact subsets of the unit ball has a limit point (and that limit point is itself a compact set). Application As an example of its use, the isoperimetric problem can be shown to have a solution. That is, there exists a curve of fixed length that encloses the maximum area possible. Other problems likewise can be shown to have a solution: Lebesgue's universal covering problem for a convex universal cover of minimal size for the collection of all sets in the plane of unit diameter, the maximum inclusion problem, and the Moser's worm problem for a convex universal cover of minimal size for the collection of planar curves of unit length.

Frederik Louis Wilhelm Hellesen (2 February 1836 – 22 December 1892) was a Danish inventor and industrialist. In 1887 he designed what is thought to be the first dry cell battery based on the Leclanché cell design. The same year he founded the company W. Hellesen In 1889 he sold his first batteries to the Danish Telephone Company. The same year a young chemist Valdemar Ludvigsen (1861–1939) came to the factory helping by the further development of the batteries. When Frederik Hellesen died in 1892 his widow took over the company with the help of Ludvigsen. In 1906 V. Ludvigsen became the sole owner of the factory with the name A/S Hellesens Enke & V. Ludvigsen. (later known as A/S Tudor-Hellesens, A/S Hellesens, and GN Hellesens), now defunct. Today the Hellesens brand name is owned by Duracell. In 1992 the Danish company was sold to GP Batteries International in Singapore belonging to Gold Peak Industries Ltd. Hong Kong. In 2005 the last factory in Thisted was closed and all machinery were shipped to a new factory in Malaysia.

It specialised in signal processing and mixed-signal chips for the consumer electronics market and had engineering and sales offices throughout Asia-Pacific, Europe, and the United States. In 2014, it was acquired by Cirrus Logic for £291 million. History Wolfson Microelectronics plc was started in 1984 by David Milne and Jim Reid. Within a year, the company had 20 employees and a deal with Fujitsu. Wolfson grew and floated on the London Stock Exchange in 2003 and be listed in the FTSE 250. Both Milne and Reid had connections with the University of Edinburgh; Reid attained a First Class Honours degree in EEE, and Milne directed the Wolfson Microelectronics Institute at King's Buildings from 1973 to 1985. In February, 2007, when Milne chose to step down, he was replaced in his CEO role by Dave Shrigley, previously Vice-President at Intel Corporation. His departure was one of a number of executive changes in late 2006, as Financial Director George Elliott also stood down. In 2006, Milne was declared Entrepreneur of the Year by the CBI, and Wolfson named Company of the Year. In November 2006 David Shrigley became the CEO of Wolfson, his first appointment at this level: he had previously worked for Intel in the Asia-Pacific region, and held directorships elsewhere. In 2007, Wolfson acquired Sonaptic Ltd, consisting of former Sensaura employees, intending
https://en.wikipedia.org/wiki/Protein%20dispersibility%20index
The Protein Dispersibility Index (PDI) is a means of comparing the solubility of a protein in water, and is widely used in the soybean product industry. A sample of the soybeans are ground, mixed with a specific quantity of water, and the two are then blended together at a specific rpm for a specific time. The resulting mixture and original bean flour then have their protein content measured using a combustion test, and the PDI is calculated as the percentage of the protein in the mix divided by the percentage in the flour - a PDI of 100 therefore indicates total solubility. It has been shown that the PDI can be affected, not only by the type of soybean used, but also by manufacturing processes - heat has been shown to lower the PDI. The PDI required of a soyflour is dependent on the purpose to which the soybeans are to be put. Manufacturers of soymilk and tofu products want a high PDI to ensure the maximum protein content in their products. However, manufacturers of soy-based fish feed require a low PDI to avoid loss of valuable protein into the surrounding water. References Dudley-Cash, W.A. 1999.

https://en.wikipedia.org/wiki/Soybean%20meal
Soybean meal is used in food and animal feeds, principally as a protein supplement, but also as a source of metabolizable energy. Typically 1 bushel (i.e. 60 lbs. or 27.2 kg) of soybeans yields 48 lbs. (21.8 kg) of soybean meal. Soybean meal is produced as a co-product of soybean oil extraction. Some, but not all, soybean meal contains ground soybean hulls. Soybean meal is heat-treated during production, to denature the trypsin inhibitors of soybeans, which would otherwise interfere with protein digestion. Major kinds of soybean meal Three main kinds of soybean meal are produced: • Full-fat soybean meal, made from whole soybeans. It has a high metabolizable energy concentration. (For example, metabolizable energy for swine in this product is about 3.69 megacalories (i.e. 15.4 MJ) per kg dry matter.) Crude protein concentration is about 38 percent (as fed). This kind of product is sometimes fed to various classes of livestock. • Defatted soybean meal, containing no hulls. This product has an intermediate energy concentration. (For example, metabolizable energy for swine in this product is about 3.38 megacalories (i.e. 14.1 MJ) per kg dry matter.) Crude protein concentration is about 48 percent. This percentage [which is commonly used in describing the product] is calculated at the typical as-fed moisture content of 88 percent. Thus, crude protein concentration expressed on a dry matter basis is 54 percent. This product is commonly fed to swine, broilers and layers.

https://en.wikipedia.org/wiki/Wheat%20middlings
Wheat middlings (also known as millfeed, wheat mill run, or wheat midds) are the product of the wheat milling process that is not flour. A good source of protein, fiber, phosphorus, and other nutrients, they are a useful fodder for livestock and pets. They are also being researched for use as a biofuel. Production White flour is made entirely from the endosperm or protein/starchy part of the grain, leaving behind the germ and the bran or fiber part. In addition to marketing the bran and germ as products in their own right, middlings include shorts (making up approximately 12% of the original grain, consisting of fractions of endosperm, bran, and germ with an average particle size of 500-900 microns) and red dog (actually a low-grade flour, making up approximately 3% of the original grain, consisting of fractions of endosperm and bran, with an average particle size of 100-300 microns). The middlings include those portions of the wheat kernel that are richest in proteins, vitamins, lipids and minerals. For example, highly refined patent flour may contain only 10 to 12% of the total thiamine and niacin, 20% of the phosphorus, and 50% of the calcium of the parent grain. Classification inconsistencies The term is somewhat imprecise, as it does not take into account the various mill streams and proportions that are combined and ultimately constitute the product's final composition. As a consequence of this inconsistent terminology, difficulties are encountered when ascertainin
https://en.wikipedia.org/wiki/Fisher%27s%20noncentral%20hypergeometric%20distribution
In probability theory and statistics, Fisher's noncentral hypergeometric distribution is a generalization of the hypergeometric distribution where sampling probabilities are modified by weight factors. It can also be defined as the conditional distribution of two or more binomially distributed variables dependent upon their fixed sum. The distribution may be illustrated by the following urn model. Assume, for example, that an urn contains m1 red balls and m2 white balls, totalling N = m1 + m2 balls. Each red ball has the weight ω1 and each white ball has the weight ω2. We will say that the odds ratio is ω = ω1 / ω2. Now we are taking balls randomly in such a way that the probability of taking a particular ball is proportional to its weight, but independent of what happens to the other balls. The number of balls taken of a particular color follows the binomial distribution. If the total number n of balls taken is known then the conditional distribution of the number of taken red balls for given n is Fisher's noncentral hypergeometric distribution. To generate this distribution experimentally, we have to repeat the experiment until it happens to give n balls. If we want to fix the value of n prior to the experiment then we have to take the balls one by one until we have n balls. The balls are therefore no longer independent. This gives a slightly different distribution known as Wallenius' noncentral hypergeometric distribution. It is far from obvious why these two distributio

In mathematics, the Caristi fixed-point theorem (also known as the Caristi–Kirk fixed-point theorem) generalizes the Banach fixed-point theorem for maps of a complete metric space into itself. Caristi's fixed-point theorem modifies the -variational principle of Ekeland (1974, 1979). The conclusion of Caristi's theorem is equivalent to metric completeness, as proved by Weston (1977). The original result is due to the mathematicians James Caristi and William Arthur Kirk. Caristi fixed-point theorem can be applied to derive other classical fixed-point results, and also to prove the existence of bounded solutions of a functional equation. Statement of the theorem Let be a complete metric space. Let and be a lower semicontinuous function from into the non-negative real numbers. Suppose that, for all points in Then has a fixed point in that is, a point such that The proof of this result utilizes Zorn's lemma to guarantee the existence of a minimal element which turns out to be a desired fixed point.

https://en.wikipedia.org/wiki/PMOS%20logic
PMOS or pMOS logic (from p-channel metal–oxide–semiconductor) is a family of digital circuits based on p-channel, enhancement mode metal–oxide–semiconductor field-effect transistors (MOSFETs). In the late 1960s and early 1970s, PMOS logic was the dominant semiconductor technology for large-scale integrated circuits before being superseded by NMOS and CMOS devices. History and application Mohamed Atalla and Dawon Kahng manufactured the first working MOSFET at Bell Labs in 1959. They fabricated both PMOS and NMOS devices but only the PMOS devices were working. It would be more than a decade before contaminants in the manufacturing process (particularly sodium) could be managed well enough to manufacture practical NMOS devices. Compared to the bipolar junction transistor, the only other device available at the time for use in an integrated circuit, the MOSFET offers a number of advantages: Given semiconductor device fabrication processes of similar precision, a MOSFET requires only 10% of the area of a bipolar junction transistor. The main reason is that the MOSFET is self-insulating and does not require p–n junction isolation from neighboring components on the chip. A MOSFET requires fewer process steps and is therefore simpler and cheaper to manufacture (one diffusion doping step compared to four for a bipolar process). Since there is no static gate current for a MOSFET, the power consumption of an integrated circuit based on MOSFETs can be lower. Disadvantages relative

https://en.wikipedia.org/wiki/CPEB
CPEB, or cytoplasmic polyadenylation element binding protein, is a highly conserved RNA-binding protein that promotes the elongation of the polyadenine tail of messenger RNA. CPEB most commonly activates the target RNA for translation, but can also act as a repressor, dependent on its phosphorylation state. In animals, CPEB is expressed in several alternative splicing isoforms that are specific to particular tissues and functions, including the self-cleaving Mammalian CPEB3 ribozyme. CPEB was first identified in Xenopus oocytes and associated with meiosis; a role has also been identified in the spermatogenesis of Caenorhabditis elegans. CPEB is involved in closed-loop regulation of mRNAs that keeps them inactive. The closed-loop structure between the 3'UTR and 5'UTR inhibits translation. This has been observed in Xenopus laevis in which eIF4E bound to the 5' cap interacts with Maskin bound to CPEB on the 3' UTR creating translationally inactive transcripts. This translational inhibition is lifted once CPEB is phosphorylated, displacing the Maskin binding site, allowing for the polymerization of the PolyA tail, which can recruit the translational machinery by means of PABP. However, it is important to note that this mechanism has been under great scrutiny. Role in memory Drosophila Orb2 binds to genes implicated in long-term memory. An isoform of CPEB found in the neurons of the sea slug Aplysia californica, as well as in Drosophila, mice, and humans, contains an N-terminal
https://en.wikipedia.org/wiki/Cytoplasmic%20polyadenylation%20element
The cytoplasmic polyadenylation element (CPE) is a sequence element found in the 3' untranslated region of messenger RNA. While several sequence elements are known to regulate cytoplasmic polyadenylation, CPE is the best characterized. The most common CPE sequence is UUUUAU, though there are other variations. Binding of CPE binding protein (CPEB) to this region promotes the extension of the existing polyadenine tail and, in general, activation of the mRNA for protein translation. This elongation occurs after the mRNA has been exported from the nucleus to the cytoplasm. A longer poly(A) tail attracts more cytoplasmic polyadenine binding proteins (PABPs) which interact with several other cytoplasmic proteins that encourage the mRNA and the ribosome to associate. The lengthening of the poly(A) tail thus has a role in increasing translational efficiency of the mRNA. The polyadenine tails are extended from approximately 40 bases to 150 bases. Cytoplasmic polyadenylation should be distinguished from nuclear polyadenylation; cytoplasmic polyadenylation occurs in the cytoplasm in specific mRNAs as opposed to occurring in the nucleus and affecting almost all eukaryotic mRNAs. Among other functions, a prominent role for the CPE has been identified in oogenesis, spermatogenesis, mitosis, and the growth of new synapses The role of the CPE was first characterized in Xenopus oocytes and embryos but recent research has identified roles for the CPE in somatic cells.

https://en.wikipedia.org/wiki/Ferroelasticity
Ferroelasticity is a phenomenon in which a material may exhibit a spontaneous strain. Usually, a crystal has two or more stable orientational states in the absence of mechanical stress or electric field, i.e. remanent states, and can be reproducibly switched between states by the application of mechanical stress. In ferroics, ferroelasticity is the mechanical equivalent of ferroelectricity and ferromagnetism. When stress is applied to a ferroelastic material, a phase change will occur in the material from one phase to an equally stable phase, either of different crystal structure (e.g. cubic to tetragonal), or of different orientation (a 'twin' phase). This stress-induced phase change results in a spontaneous strain in the material. The shape memory effect and superelasticity are manifestations of ferroelasticity. Nitinol (nickel titanium), a common ferroelastic alloy, can display either superelasticity or the shape-memory effect at room temperature, depending on the nickel-to-titanium ratio.

https://en.wikipedia.org/wiki/Hamada%27s%20equation
In corporate finance, Hamada’s equation is an equation used as a way to separate the financial risk of a levered firm from its business risk. The equation combines the Modigliani–Miller theorem with the capital asset pricing model. It is used to help determine the levered beta and, through this, the optimal capital structure of firms. It was named after Robert Hamada, the Professor of Finance behind the theory. Hamada’s equation relates the beta of a levered firm (a firm financed by both debt and equity) to that of its unlevered (i.e., a firm which has no debt) counterpart. It has proved useful in several areas of finance, including capital structuring, portfolio management and risk management, to name just a few. This formula is commonly taught in MBA Corporate Finance and Valuation classes. It is used to determine the cost of capital of a levered firm based on the cost of capital of comparable firms. Here, the comparable firms would be the ones having similar business risk and, thus, similar unlevered betas as the firm of interest. Equation The equation is where βL and βU are the levered and unlevered betas, respectively, T the tax rate and the leverage, defined here as the ratio of debt, D, to equity, E, of the firm. The importance of Hamada's equation is that it separates the risk of the business, reflected here by the beta of an unlevered firm, βU, from that of its levered counterpart, βL, which contains the financial risk of leverage.

https://en.wikipedia.org/wiki/Interclass%20correlation
In statistics, the interclass correlation (or interclass correlation coefficient) is a measure of a relation between two variables of different classes (types), such as the weights of 10-year-old sons and of their 40-year-old fathers. Deviations of a variable are measured from the mean of the data for that class – a son's weight minus the mean of all the sons' weights, or a father's weight minus the mean of all the fathers' weights. The Pearson correlation coefficient is the most commonly used measure of interclass correlation. The interclass correlation contrasts with the intraclass correlation between variables of the same class, such as the weights of women and of their identical twins; here deviations are measured from the mean of all members of the single class, in this example of all women in the set of identical twins.

Genetic stock centers are collections of pure genetic stock available for use in research. They are often housed at research universities, and include everything from single cell life to plants, fish, and small mammals such as mice and rats. Genetic Stock Centers often charge for research stock on a two tier scale, with non profit researchers getting stock at a lower cost than commercial researchers. Dr Myron Gordon, for example, established the Xiphophorus genetic stock center in 1939 to raise pure strains when he realized that certain Xiphophorus hybrids would be useful in cancer research. He understood that his research could not be duplicated by other scientists without pure genetic stock to use as a base. The strains that Dr Gordon started remain pure and are used to this day.

https://en.wikipedia.org/wiki/Tolmetin
Tolmetin () is a nonsteroidal anti-inflammatory drug (NSAID) of the heterocyclic acetic acid derivative class. Tolmetin was originally approved by the US FDA in 1976, but may no longer be readily available in the US, generics may be available. It is available internationally. It is used primarily to reduce hormones that cause pain, swelling, tenderness, and stiffness in conditions such as osteoarthritis and rheumatoid arthritis, including juvenile rheumatoid arthritis. In the United States it was marketed as Tolectin and comes as a tablet or capsule. Clinical usage Tolmetin is applicable in the treatment of rheumatoid arthritis, osteoarthrosis, pain, and ankylosing spondylitis. Mechanism of action Although the mechanism of action of tolmetin is unknown, research involving humans and animals has shown that tolmetin does not achieve anti-inflammatory response by stimulation of the adrenal or pituitary gland, but it has shown tolmetin restrains prostaglandin synthetase in vitro and reduces plasma levels of prostaglandin E, possibly causing the anti-inflammatory response. When tested in rats, tolmetin prevented experimentally stimulated polyarthritis and reduced inflammation. In patients with rheumatoid arthritis or osteoarthritis tolmetin was as effective as aspirin and indometacin, although the occurrence of mild gastrointestinal adverse effects and tinnitus was lower in patients treated with tolmetin than it was with aspirin-treated patients and the occurrence of advers
https://en.wikipedia.org/wiki/HIV-1%20protease
HIV-1 protease (PR) is a retroviral aspartyl protease (retropepsin), an enzyme involved with peptide bond hydrolysis in retroviruses, that is essential for the life-cycle of HIV, the retrovirus that causes AIDS. HIV protease cleaves newly synthesized polyproteins (namely, Gag and Gag-Pol) at nine cleavage sites to create the mature protein components of an HIV virion, the infectious form of a virus outside of the host cell. Without effective HIV protease, HIV virions remain uninfectious. Structure Mature HIV protease exists as a 22 kDa homodimer, with each subunit made up of 99 amino acids. A single active site lies between the identical subunits and has the characteristic Asp-Thr-Gly (Asp25, Thr26 and Gly27) catalytic triad sequence common to aspartic proteases. As HIV-1 PR can only function as a dimer, the mature protease contains two Asp25 amino acids, one from each monomer, that act in conjunction with each other as the catalytic residues. Additionally, HIV protease has two molecular "flaps" which move a distance of up to 7 Å when the enzyme becomes associated with a substrate. This can be visualized with animations of the flaps opening and closing. Biosynthesis Precursor The Gag-Pol polyprotein, which contains premature coding proteins, including HIV-1 PR. PR is located between the reverse transcriptase (which is at the C-terminus of PR) and the p6pol (which is at the N-terminus of PR) of the transframe region (TFR).

James J. Kay (June 18, 1954 – May 30, 2004) was an ecological scientist and policy-maker. He was a respected physicist best known for his theoretical work on complexity and thermodynamics. Biography James Kay held a BS in physics from McGill University and a Ph.D. in systems design engineering from the University of Waterloo. His Ph.D. thesis was entitled Self-Organization in Living Systems. Much of his work relates to integrating thermodynamics into an understanding of self-organization in biological systems. For example, when water in a pot is heated, it will spontaneously form convection currents such as Bénard_cell. This is an example where as the amount of energy available to a system increases, the system self-organizes in order to dissipate energy more efficiently. Kay has examined how similar types of self-organization can occur within living systems at the level of individual organisms and ecosystems. In other words, organisms and ecosystems evolve to use the maximum amount of energy available to them. This has been backed up by studies showing that more mature ecosystems such as old growth forests are cooler (i.e. dissipate more incoming energy) than clear cuts or bare rock that receive the same amount of energy. Kay was an associate professor of environment and resource studies at the University of Waterloo, with cross-appointments in systems design engineering, geography, management sciences, and the School of Planning. He was also cross-posted to the Sch

https://en.wikipedia.org/wiki/Smart%20cut
Smart cut is a technological process that enables the transfer of very fine layers of crystalline silicon material onto a mechanical support. It was invented by Michel Bruel of CEA-Leti, and was protected by US patent 5374564. The application of this technological procedure is mainly in the production of silicon-on-insulator (SOI) wafer substrates. The role of SOI is to electronically insulate a fine layer of monocrystalline silicon from the rest of the silicon wafer; an ultra-thin silicon film is transferred to a mechanical support, thereby introducing an intermediate, insulating layer. Semiconductor manufacturers can then fabricate integrated circuits on the top layer of the SOI wafers using the same processes they would use on plain silicon wafers. The sequence of illustrations pictorially describes the process involved in fabricating SOI wafers using the smart cut technology.

https://en.wikipedia.org/wiki/CHD7
Chromodomain-helicase-DNA-binding protein 7 is an ATP-dependent 'chromatin' or 'nucleosome' remodeling factor that in humans is encoded by the CHD7 gene. CHD7 is an ATP-dependent chromatin remodeler homologous to the Drosophila trithorax-group protein Kismet. Mutations in CHD7 are associated with CHARGE syndrome. This protein belongs to a larger group of ATP-dependent chromatin remodeling complexes, the CHD subfamily. Model organisms Model organisms have been used in the study of CHD7 function. A conditional knockout mouse line, called Chd7tm2a(EUCOMM)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 five 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 abnormal pelvic elevation in a modified SHIRPA test and have a high incidence of Bergmeister's papilla in both eyes. When the brains of heterozygous animals were studied, an absence of corpus callosum was observed. Clinical Mutations in this gene have been associated with the CHARGE syndrome.

https://en.wikipedia.org/wiki/Shale%20gouge%20ratio
Shale Gouge Ratio (typically abbreviated to SGR) is a mathematical algorithm that aims to predict the fault rock types for simple fault zones developed in sedimentary sequences dominated by sandstone and shale. The parameter is widely used in the oil and gas exploration and production industries to enable quantitative predictions to be made regarding the hydrodynamic behavior of faults. Definition At any point on a fault surface, the shale gouge ratio is equal to the net shale/clay content of the rocks that have slipped past that point. The SGR algorithm assumes complete mixing of the wall-rock components in any particular 'throw interval'. The parameter is a measure of the 'upscaled' composition of the fault zone. Application to hydrocarbon exploration Hydrocarbon exploration involves identifying and defining accumulations of hydrocarbons that are trapped in subsurface structures. These structures are often segmented by faults. For a thorough trap evaluation, it is necessary to predict whether the fault is sealing or leaking to hydrocarbons and also to provide an estimate of how 'strong' the fault seal might be. The 'strength' of a fault seal can be quantified in terms of subsurface pressure, arising from the buoyancy forces within the hydrocarbon column, that the fault can support before it starts to leak. When acting on a fault zone this subsurface pressure is termed capillary threshold pressure. For faults developed in sandstone and shale sequences, the first

Chromobox protein homolog 1 is a protein that in humans is encoded by the CBX1 gene. Function The protein is localized at heterochromatin sites, where it mediates gene silencing. Model organisms Model organisms have been used in the study of CBX1 function. A conditional knockout mouse line, called Cbx1tm1a(EUCOMM)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 — at the Wellcome Trust Sanger Institute.

Chromobox protein homolog 3 is a protein that is encoded by the CBX3 gene in humans. At the nuclear envelope, the nuclear lamina and heterochromatin are adjacent to the inner nuclear membrane. The protein encoded by this gene binds DNA and is a component of heterochromatin. This protein also can bind lamin B receptor, an integral membrane protein found in the inner nuclear membrane. The dual binding functions of the encoded protein may explain the association of heterochromatin with the inner nuclear membrane. Two transcript variants encoding the same protein but differing in the 5' UTR, have been found for this gene. Interactions CBX3 has been shown to interact with PIM1, Ki-67, Lamin B receptor, CBX5 and CBX1. See also Heterochromatin protein 1 References Further reading External links Transcription factors
https://en.wikipedia.org/wiki/Scheie%20syndrome
Scheie syndrome is a disease caused by a deficiency in the enzyme iduronidase, leading to the buildup of glycosaminoglycans (GAGs) in the body. It is the most mild subtype of mucopolysaccharidosis type I; the most severe subtype of this disease is called Hurler Syndrome. Scheie syndrome is characterized by corneal clouding, facial dysmorphism, and normal lifespan. People with this condition may have aortic regurgitation. Symptoms The symptoms of Scheie syndrome are variable, but are milder than Hurler Syndrome. Symptoms may begin to appear by age 5, but affected children are often not diagnosed until after age 10. Patients with Scheie Syndrome may have normal intelligence, or they may have mild learning impairments or psychiatric problems. Glaucoma, retinal degeneration, and clouded corneas may cause visual impairments. Aortic valve disease may be present, along with carpal tunnel syndrome, deformed hands and feet, stiff joints, or sleep apnea. People with Scheie syndrome may live into adulthood. Genetics Children with Scheie Syndrome carry two defective copies of the IDUA gene, which has been mapped to the 4p16.3 site on chromosome 4. This is the gene which encodes for the protein iduronidase. All patients with subtypes of MPS I have mutations in the same gene, leading to deficiencies of the same enzyme. However, patients with Scheie Syndrome have a greater level of iduronidase activity than patients with Hurler Syndrome. Because Scheie syndrome is an autosomal reces

Daniel Vorländer (11 June 1867 – 8 June 1941) was a German chemist who synthesized most of the liquid crystals known until his retirement in 1935. Vorländer was born in Eupen in Rhenish Prussia. He studied chemistry at Kiel, Munich, and Berlin, after which he became a professor at University of Halle-Wittenberg. Vorländer applied his knowledge of molecular structure to select those exhibiting the crystalline liquid state. In particular a linear molecular geometry was conductive. "Over the years Vorländer and his students synthesized hundreds of liquid crystalline compounds. An interesting discovery was that amongst the slimy liquid crystals were many soap and soap-like compounds." (Dunmur & Sluckin p 48) Vorländer served as a volunteer during World War I, during which he received the Iron Cross. He died in Halle.

https://en.wikipedia.org/wiki/Magnetobiology
Magnetobiology is the study of biological effects of mainly weak static and low-frequency magnetic fields, which do not cause heating of tissues. Magnetobiological effects have unique features that obviously distinguish them from thermal effects; often they are observed for alternating magnetic fields just in separate frequency and amplitude intervals. Also, they are dependent of simultaneously present static magnetic or electric fields and their polarization. Magnetobiology is a subset of bioelectromagnetics. Bioelectromagnetism and biomagnetism are the study of the production of electromagnetic and magnetic fields by biological organisms. The sensing of magnetic fields by organisms is known as magnetoreception. Biological effects of weak low frequency magnetic fields, less than about 0.1 millitesla (or 1 Gauss) and 100 Hz correspondingly, constitutes a physics problem. The effects look paradoxical, for the energy quantum of these electromagnetic fields is by many orders of value less than the energy scale of an elementary chemical act. On the other hand, the field intensity is not enough to cause any appreciable heating of biological tissues or irritate nerves by the induced electric currents. Effects An example of a magnetobiological effect is the magnetic navigation by migrant animals by means of magnetoreception. Many animal orders, such as certain birds, marine turtles, reptiles, amphibians and salmonoid fishes are able to detect small variations of the geomagn

https://en.wikipedia.org/wiki/Hyalophane
Hyalophane or jaloallofane is a crystalline mineral, part of the feldspar group of tectosilicates. It is considered a barium-rich potassium feldspar. Its chemical formula is , and it has a hardness of 6 to . The name hyalophane comes from the Greek , meaning "glass", and meaning "to appear". An occurrence of hyalophane was discovered in 1855 in Lengenbach Quarry, Imfield, Binn valley, municipality of Binn, Canton of Valais, Switzerland. The mineral is found predominantly in Europe, with occurrences in Switzerland, Australia, Bosnia, Germany, Japan, New Jersey, and the west coast of North America. Hyalophane may be found in manganese deposits in compact metamorphic zones. Hyalophane has a monoclinic crystallography, with cell properties a = 8.52 Å, b = 12.95 Å, c = 7.14 Å, and β = 116°. Optically, the material exhibits biaxial birefringence, with refractive index values of nα = 1.542, nβ = 1.545, and nγ = 1.547 and a maximum birefringence of δ = 0.005. It has weak dispersion and low surface relief. Hyalophane has sometimes been used as a gemstone.

https://en.wikipedia.org/wiki/IKK2
IKK-β also known as inhibitor of nuclear factor kappa-B kinase subunit beta is a protein that in humans is encoded by the IKBKB (inhibitor of kappa light polypeptide gene enhancer in B-cells, kinase beta) gene. Function IKK-β is an enzyme that serves as a protein subunit of IκB kinase, which is a component of the cytokine-activated intracellular signaling pathway involved in triggering immune responses. IKK's activity causes activation of a transcription factor known as Nuclear Transcription factor kappa-B or NF-κB. Activated IKK-β phosphorylates a protein called the inhibitor of NF-κB, IκB (IκBα), which binds NF-κB to inhibit its function. Phosphorylated IκB is degraded via the ubiquitination pathway, freeing NF-κB, and allowing its entry into the nucleus of the cell where it activates various genes involved in inflammation and other immune responses. Clinical significance IKK-β plays a significant role in brain cells following a stroke. If NF-κB activation by IKK-β is blocked, damaged cells within the brain stay alive, and according to a study performed by the University of Heidelberg and the University of Ulm, the cells even appear to make some recovery. Inhibition of IKK and IKK-related kinases has been investigated as a therapeutic option for the treatment of inflammatory diseases and cancer.

Moodna Creek is a small tributary of the Hudson River that drains eastern Orange County, New York. At 15.5 miles (25 km) in length from its source at the confluence of Cromline Creek and Otter Kill west of Washingtonville, it is the longest stream located entirely within the county. Despite its small size relative to the Hudson, it has been a major influence on the topography of eastern central Orange County. Its watershed, including not only both its parent streams but Woodbury Creek as well, reaches as far inland as Warwick as well as 21 other area communities. Near Salisbury Mills it is crossed by the Moodna Viaduct, the longest actively used railroad trestle east of the Mississippi. Name Before European contact, the creek was known as Waoraneck, which was also the name of a tribe in the area. Most early records name the creek Murderer's Creek. One theory holds that "Moodna" is a corruption of the Dutch word moordenaars, meaning "murderers." Local lore has it that the name came from the massacre of the Stacys, an early family of settlers, along its banks. However, there is no evidence of any such murder actually having taken place. Writer Nathaniel Parker Willis, while living in Cornwall, near the creek's mouth, in the mid-19th century, popularized the name "Moodna." He claimed that the "Murderers' Creek" name was a corruption of the name of a chief, likely Maringamus of the Waoraneck, who lived near its banks. By the dawn of the 20th century, "Moodna Creek" was commo

Synthetic-music mobile application format, abbreviated SMAF, is a music data format specified by Yamaha for portable electronic devices, such as cell phones and PDAs. The file extension for SMAF is .MMF and is common as ringtones for mobile phones with one of five sound chips. SMAF resembles MIDI, but also supports graphics and PCM sound playback. Its MIDI playback is produced via FM synthesis or PCM sample-based synthesis, where instrument data (parameters and/or PCM samples) is stored within the .MMF file itself, similar to module files. This enables users to create custom instruments, which will sound exactly the same on devices with the same chip.

https://en.wikipedia.org/wiki/Transplastomic%20plant
A transplastomic plant is a genetically modified plant in which genes are inactivated, modified or new foreign genes are inserted into the DNA of plastids like the chloroplast instead of nuclear DNA. Currently, the majority of transplastomic plants are a result of chloroplast manipulation due to poor expression in other plastids. However, the technique has been successfully applied to the chromoplasts of tomatoes. Chloroplasts in plants are thought to have originated from an engulfing event of a photosynthetic bacteria (cyanobacterial ancestor) by a eukaryote. There are many advantages to chloroplast DNA manipulation because of its bacterial origin. For example, the ability to introduce multiple genes (operons) in a single step instead of many steps and the simultaneous expression of many genes with its bacterial gene expression system. Other advantages include the ability to obtain organic products like proteins at a high concentration and the fact that production of these products will not be affected by epigenetic regulation. The reason for product synthesis at high concentrations is because a single plant cell can potentially carry up to 100 chloroplasts. If all these plastids are transformed, all of them can express the introduced foreign genes. This is may be advantageous compared to transformation of the nucleus, because the nucleus typically contains only one or two copies of the gene. The advantages provided by chloroplast DNA manipulation has seen growing intere

Kaspichan (, ) is a town in central northeastern Bulgaria, part of Shumen Province. It is located in the eastern Danubian Plain, some from the major Black Sea port Varna and around from the key Danube ports of Ruse and Silistra. As of December 2009, the town has a population of 3,260 inhabitants. Kaspichan is an important railway junction linking Varna with Sofia and Russe, Sofia both through a railway line and the Hemus motorway. Geography Kaspichan Municipality is located in the central part of northeastern Bulgaria. It borders the municipalities of Shumen, Novi Pazar and Provadia.The administrative-territorial division includes nine settlements. It occupies an extremely important strategic position in northeastern Bulgaria. The town of Kaspichan is located 66 km from Varna and 120 km on average from the two major Danube ports of Ruse and Silistra. The railway station of the city is an important communication and transport hub in Northeastern Bulgaria. Located on the town's land is the village of the same name, which has no land of its own. History According to the early 20th-century historian Vasil Mikov, the origin of the name of the settlement is narrow, as it is identical to the name of their tribal leader. Kaspichan began its development as a market, and in 1866 as a railway station, Shumli, on the first railway line from Ruse–Varna. The infrastructural importance of the station for the region grew rapidly after the Liberation. Evidence of holding rural-municip

Tre recombinase is an experimental enzyme that in lab tests has removed DNA inserted by HIV from infected cells. Through selective mutation, Cre recombinase which recognizes loxP sites are modified to identify HIV long terminal repeats (loxLTR) instead. As a result, instead of performing Cre-Lox recombination, the new enzyme performs recombination at HIV provirus sites. The structure of Tre in complex with loxLTR has been resolved (), allowing for analyzing the roles of individual mutations. References External links Genetics Molecular biology
https://en.wikipedia.org/wiki/Junction%20temperature
Junction temperature, short for transistor junction temperature, is the highest operating temperature of the actual semiconductor in an electronic device. In operation, it is higher than case temperature and the temperature of the part's exterior. The difference is equal to the amount of heat transferred from the junction to case multiplied by the junction-to-case thermal resistance. Microscopic effects Various physical properties of semiconductor materials are temperature dependent. These include the diffusion rate of dopant elements, carrier mobilities and the thermal production of charge carriers. At the low end, sensor diode noise can be reduced by cryogenic cooling. On the high end, the resulting increase in local power dissipation can lead to thermal runaway that may cause transient or permanent device failure. Maximum junction temperature calculation Maximum junction temperature (sometimes abbreviated TJMax) is specified in a part's datasheet and is used when calculating the necessary case-to-ambient thermal resistance for a given power dissipation. This in turn is used to select an appropriate heat sink if applicable. Other cooling methods include thermoelectric cooling and coolants. In modern processors from manufacturer such as Intel, AMD, Qualcomm, the core temperature is measured by a network of sensors. Every time the temperature sensing network determines that a rise above the specified junction temperature (), is imminent, measures such as clock gating, cl
https://en.wikipedia.org/wiki/Calibrated%20probability%20assessment
Calibrated probability assessments are subjective probabilities assigned by individuals who have been trained to assess probabilities in a way that historically represents their uncertainty. For example, when a person has calibrated a situation and says they are "80% confident" in each of 100 predictions they made, they will get about 80% of them correct. Likewise, they will be right 90% of the time they say they are 90% certain, and so on. Calibration training improves subjective probabilities because most people are either "overconfident" or "under-confident" (usually the former). By practicing with a series of trivia questions, it is possible for subjects to fine-tune their ability to assess probabilities. For example, a subject may be asked: True or False: "A hockey puck fits in a golf hole" Confidence: Choose the probability that best represents your chance of getting this question right... 50% 60% 70% 80% 90% 100% If a person has no idea whatsoever, they will say they are only 50% confident. If they are absolutely certain they are correct, they will say 100%. But most people will answer somewhere in between. If a calibrated person is asked a large number of such questions, they will get about as many correct as they expected. An uncalibrated person who is systematically overconfident may say they are 90% confident in a large number of questions where they only get 70% of them correct. On the other hand, an uncalibrated person who is systematically underconfident may

The magnetorotational instability (MRI) is a fluid instability that causes an accretion disk orbiting a massive central object to become turbulent. It arises when the angular velocity of a conducting fluid in a magnetic field decreases as the distance from the rotation center increases. It is also known as the Velikhov–Chandrasekhar instability or Balbus–Hawley instability in the literature, not to be confused with the electrothermal Velikhov instability. The MRI is of particular relevance in astrophysics where it is an important part of the dynamics in accretion disks. Gases or liquids containing mobile electrical charges are subject to the influence of a magnetic field. In addition to hydrodynamical forces such as pressure and gravity, an element of magnetized fluid also feels the Lorentz force where is the current density and is the magnetic field vector. If the fluid is in a state of differential rotation about a fixed origin, this Lorentz force can be surprisingly disruptive, even if the magnetic field is very weak. In particular, if the angular velocity of rotation decreases with radial distance the motion is unstable: a fluid element undergoing a small displacement from circular motion experiences a destabilizing force that increases at a rate which is itself proportional to the displacement. This process is known as the Magnetorotational Instability, or "MRI". In astrophysical settings, differentially rotating systems are very common and magnetic fields are

https://en.wikipedia.org/wiki/Diathermancy
Diathermancy (from "dia" through and "thermē" heat) is the property of some fluids that allows rays of light through them without itself being heated. A diathermanous substance is thus "permeable" by heat. Diathermancy was first described by German physicist and chemist Heinrich Gustav Magnus in the 1800s. Air is diathermanous; therefore atmospheric air is not heated by sunshine. Atmospheric air is heated by long-wave thermal radiation emitted by soil, and especially, by water on the Earth's surface. Water is not diathermanous, and it is heated directly by sunshine. Atmospheric heating from oceanic waters Atmospheric heat comes from long-wave radiation from the soil and, mostly, from the water surface (oceans, lakes, rivers), because water is a not diathermanous body and covers three quarters of Earth's surface. Diathermancy cause subsidence above damp or water surfaces. That is because these areas tend to absorb heat radiation directly from the Sun but very slowly and also emit this radiation to the atmosphere very slowly. Therefore, cold ocean currents have very clear skies, without clouds, because subsidence from cold and heavy air avoids or limits convection because they are opposite processes.

https://en.wikipedia.org/wiki/List%20of%20optimization%20software
Given a transformation between input and output values, described by a mathematical function , optimization deals with generating and selecting the best solution from some set of available alternatives, by systematically choosing input values from within an allowed set, computing the output of the function and recording the best output values found during the process. Many real-world problems can be modeled in this way. For example, the inputs can be design parameters of a motor, the output can be the power consumption, or the inputs can be business choices and the output can be the obtained profit. An optimization problem, in this case a minimization problem, can be represented in the following way Given: a function f : A R from some set A to the real numbers Search for: an element x0 in A such that f(x0) ≤ f(x) for all x in A. In continuous optimization, A is some subset of the Euclidean space Rn, often specified by a set of constraints, equalities or inequalities that the members of A have to satisfy. In combinatorial optimization, A is some subset of a discrete space, like binary strings, permutations, or sets of integers. The use of optimization software requires that the function f is defined in a suitable programming language and connected at compile or run time to the optimization software. The optimization software will deliver input values in A, the software module realizing f will deliver the computed value f(x) and, in some cases, additional information about

https://en.wikipedia.org/wiki/Inoki%20Genome%20Federation
(IGF) was a Japanese professional wrestling and mixed martial arts promotion founded by Antonio Inoki in 2007. History Antonio Inoki left New Japan Pro-Wrestling, a promotion he founded in 1972, to start the IGF. The first IGF show was held on June 29, 2007 at the Sumo Hall in Tokyo, Japan. The show's main event was a match between Kurt Angle and Brock Lesnar. Shinichi Suzukawa was scheduled to face Bob Sapp in an IGF special rules Heavyweight bout on December 31, 2010, at K-1 Dynamite!! 2010. The fight was to be held under MMA rules, but the fighters wouldn't be wearing gloves. Closed-fist strikes would have been allowed, but palm strikes wouldn't have been permitted. The event was to air on HDNet in North America. However, the fight was canceled due to a last-minute contract dispute, with the Japanese audience in attendance told by the promoter involved in the dispute that Sapp “had lost his will to fight.” In 2011 the company presented a gift to Kim Jong Il, leader of North Korea as part of a diplomatic effort. In August 2014, IGF held two shows in Pyongyang, North Korea. On December 29, 2014, IGF announced a deal with PPTV to bring its programming to Chinese audiences. In 2017, Inoki created a new company, ISM, distancing himself from IGF. After that, his son-in-law Simon Inoki gained more influence in the company and created a new brand, "NEW". On March 23, 2018, Antonio Inoki sold his part of the promotion and left IGF. IGF closed on January 9, 2019. A new promoti
https://en.wikipedia.org/wiki/Chemical%20transport%20reaction
In chemistry, a chemical transport reaction describes a process for purification and crystallization of non-volatile solids. The process is also responsible for certain aspects of mineral growth from the effluent of volcanoes. The technique is distinct from chemical vapor deposition, which usually entails decomposition of molecular precursors and which gives conformal coatings. The technique, which was popularized by Harald Schäfer, entails the reversible conversion of nonvolatile elements and chemical compounds into volatile derivatives. The volatile derivative migrates throughout a sealed reactor, typically a sealed and evacuated glass tube heated in a tube furnace. Because the tube is under a temperature gradient, the volatile derivative reverts to the parent solid and the transport agent is released at the end opposite to which it originated (see next section). The transport agent is thus catalytic. The technique requires that the two ends of the tube (which contains the sample to be crystallized) be maintained at different temperatures. So-called two-zone tube furnaces are employed for this purpose. The method derives from the Van Arkel de Boer process which was used for the purification of titanium and vanadium and uses iodine as the transport agent. Cases of the exothermic and endothermic reactions of the transporting agent Transport reactions are classified according to the thermodynamics of the reaction between the solid and the transporting agent.

https://en.wikipedia.org/wiki/VLF%20Transmitter%20Cutler
The VLF Transmitter Cutler is the United States Navy's very low frequency (VLF) shore radio station at Cutler, Maine. The station provides one-way communication to submarines of the Navy's Atlantic Fleet, both on the surface and submerged. It transmits with call sign NAA, at a frequency of 24 kHz and input power of up to 1.8 megawatts, and is one of the most powerful radio transmitters in the world. Description The current Cutler Naval Station was built during 1960 and became operational on January 4, 1961. It has a transmission power of 2 megawatts. As with all VLF stations, the transmitter has a very small bandwidth, and so cannot transmit audio (speech) but only coded text messages, at a relatively low data rate. The transmission consists of a continuously encrypted minimum-shift keying (MSK) signal capable of multi channel operations. The transmitter uses the frequency 24.0 kHz. During the past it used 17.8 kHz. The callsign of the station is NAA. Antenna The extensive antenna system consists of two separate identical specialized umbrella antenna arrays, designated the “north array” and the “south array”. Each array consists of a ring of 13 tall metal masts connected at the top by a network of horizontal cables. The cables form six diamond-shaped (rhombic) "panels" radiating from the central tower at angles of 60°, so from above the antenna has a snowflake shape. The two arrays normally operate together as one antenna, but each is designed to function independently

https://en.wikipedia.org/wiki/Miami%20Rock%20Ridge
The Miami Rock Ridge is a continuous limestone outcrop which formerly encompassed a large extent of far South Florida, including portions of the Everglades ecosystem. The traditional base of the elevation ranges from northern Miami-Dade County, Florida (the approximate latitude of North Miami Beach) southward to the upper Florida Keys, and it extends southwest into Everglades National Park. The coastal ridge was traditionally a component of the endangered pine rocklands, which grew upon the length of the ridge. The environmental community consisted of a large and continuous expanse of South Florida Slash Pines (Pinus elliottii var. densa), which was interspersed by tropical hardwood hammocks. The globally imperiled pine rockland community, which also encompassed the Florida Keys and The Bahamas, supported numerous endemic plant species; 20 percent occur nowhere else in the world. The communities of the Miami Rock Ridge are maintained by wildfires, including natural fires caused by lightning strikes; this affects the vegetation and its associated inhabitants, thus maintaining a diverse ecosystem. The substrate—often consisting of marl—and climate also affects the height of vegetation; thus a mature subtropical hammock typically does not exceed on the Miami Rock Ridge. Today the original communities have been largely removed by development, and the remaining pieces of the ecosystems are scattered into tiny fragments in extreme southeast Florida; they now encompass small fract
