Bacon Number
Six Degrees of Kevin Bacon or Bacon's Law is a parlor game where players challenge each other to arbitrarily choose an actor and then connect them to another actor via a film that both actors have appeared in together, repeating this process to try to find the shortest path that ultimately leads to prolific American actor Kevin Bacon. It rests on the assumption that anyone involved in the Hollywood film industry can be linked through their film roles to Bacon within six steps. The game's name is a reference to "six degrees of separation", a concept that posits that any two people on Earth are six or fewer acquaintance links apart. In 2007, Bacon started a charitable organization called SixDegrees.org. In 2020, Bacon started a podcast called ''The Last Degree of Kevin Bacon''. History In a January 1994 interview with ''Premiere'' magazine, Kevin Bacon mentioned while discussing the film ''The River Wild'' that "he had worked with everybody in Hollywood or someone who's worked wi ...

Bachelor Of Nursing
The Bachelor of Science in Nursing (BSN, BScN) also known in some countries as a Bachelor of Nursing (BN) or Bachelor of Science (BS) with a Major in Nursing is an academic degree in the science and principles of nursing, granted by an accredited tertiary education provider. The course of study is typically three or four years. The difference in degree designation may relate to the amount of basic science courses required as part of the degree, with BScN and BSN degree curriculums requiring completion of more courses on math and natural sciences that are more typical of BSc degrees (e.g. calculus, physics, chemistry, biology) and BN curriculums more focused on nursing theory, nursing process, and teaching versions of general science topics that are adapted to be more specific and relevant to nursing practice. Nursing school students are generally required to take courses in social and behavioral sciences and liberal arts, including nutrition, anatomy, chemistry, mathematics, and Eng ...

BN (biscuit)
BN Biscuits (or Biscuiterie Nantaise) is a biscuit brand originally hailing from France, consisting of 2 golden-baked biscuits sandwiched together with a filling, originally chocolate-flavoured. It was launched in 1932, acquired by United Biscuits in 1998, and relaunched in September 2000. Biscuiterie Nantaise company was acquired by General Mills in 1973, which later sold its European assets to PepsiCo in 1992. PepsiCo later sold BN to United Biscuits in exchange for several United Biscuits snack assets (including The Smith's Snackfood Company but excluding KP Snacks). The BN range now consists of multiple different biscuit formats, but the classic sandwich biscuit range consists of two different shapes: circles and rounded squares. One side of the biscuit is decorated with one of four different faces. There are seven different flavours of the BN biscuit: chocolate, strawberry, vanilla, hazelnut, raspberry, apricot and milk chocolate. They also come in a "Mini BN" variet ...

Batch Normalization
Batch normalization (also known as batch norm) is a method used to make training of artificial neural networks faster and more stable through normalization of the layers' inputs by re-centering and re-scaling. It was proposed by Sergey Ioffe and Christian Szegedy in 2015. While the effect of batch normalization is evident, the reasons behind its effectiveness remain under discussion. It was believed that it can mitigate the problem of ''internal covariate shift'', where parameter initialization and changes in the distribution of the inputs of each layer affect the learning rate of the network. Recently, some scholars have argued that batch normalization does not reduce internal covariate shift, but rather smooths the objective function, which in turn improves the performance. However, at initialization, batch normalization in fact induces severe gradient explosion in deep networks, which is only alleviated by skip connections in residual networks. Others maintain that batch nor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dynkin Diagram
In the mathematical field of Lie theory, a Dynkin diagram, named for Eugene Dynkin, is a type of graph with some edges doubled or tripled (drawn as a double or triple line). Dynkin diagrams arise in the classification of semisimple Lie algebras over algebraically closed fields, in the classification of Weyl groups and other finite reflection groups, and in other contexts. Various properties of the Dynkin diagram (such as whether it contains multiple edges, or its symmetries) correspond to important features of the associated Lie algebra. The term "Dynkin diagram" can be ambiguous. In some cases, Dynkin diagrams are assumed to be directed, in which case they correspond to root systems and semi-simple Lie algebras, while in other cases they are assumed to be undirected, in which case they correspond to Weyl groups. In this article, "Dynkin diagram" means ''directed'' Dynkin diagram, and ''undirected'' Dynkin diagrams will be explicitly so named. Classification of semisimple ...

Bulimia Nervosa
Bulimia nervosa, also known as simply bulimia, is an eating disorder characterized by binge eating followed by purging or fasting, and excessive concern with body shape and weight. The aim of this activity is to expel the body of calories eaten from the binging phase of the process. Binge eating refers to eating a large amount of food in a short amount of time. Purging refers to the attempts to get rid of the food consumed. This may be done by vomiting or taking laxatives. Other efforts to lose weight may include the use of diuretics, stimulants, water fasting, or excessive exercise. Most people with bulimia are at a normal weight. The forcing of vomiting may result in thickened skin on the knuckles, breakdown of the teeth and effects on metabolic rate and caloric intake which cause thyroid dysfunction. Bulimia is frequently associated with other mental disorders such as depression, anxiety, borderline personality disorder, bipolar disorder and problems with drugs or alcohol ...

Boron Nitride
Boron nitride is a thermally and chemically resistant refractory compound of boron and nitrogen with the chemical formula BN. It exists in various crystalline forms that are isoelectronic to a similarly structured carbon lattice. The hexagonal form corresponding to graphite is the most stable and soft among BN polymorphs, and is therefore used as a lubricant and an additive to cosmetic products. The cubic ( zincblende aka sphalerite structure) variety analogous to diamond is called c-BN; it is softer than diamond, but its thermal and chemical stability is superior. The rare wurtzite BN modification is similar to lonsdaleite but slightly softer than the cubic form. Because of excellent thermal and chemical stability, boron nitride ceramics are used in high-temperature equipment and metal casting. Boron nitride has potential use in nanotechnology. Structure Boron nitride exists in multiple forms that differ in the arrangement of the boron and nitrogen atoms, giving rise to varyin ...

Benzyl
In organic chemistry, benzyl is the substituent or molecular fragment possessing the structure . Benzyl features a benzene ring () attached to a methylene group () group. Nomenclature In IUPAC nomenclature, the prefix benzyl refers to a substituent, for example benzyl chloride or benzyl benzoate. Benzyl is not to be confused with phenyl with the formula . The term benzylic is used to describe the position of the first carbon bonded to a benzene or other aromatic ring. For example, is referred to as a "benzylic" carbocation. The benzyl free radical has the formula . The benzyl cation or phenylcarbenium ion is the carbocation with formula ; the benzyl anion or phenylmethanide ion is the carbanion with the formula . None of these species can be formed in significant amounts in the solution phase under normal conditions, but they are useful referents for discussion of reaction mechanisms and may exist as reactive intermediates. Abbreviations The abbreviation "Bn" denotes benzyl. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Province Of Benevento
The Province of Benevento ( it, Provincia di Benevento) is a province in the Campania region of Italy. Its capital is the city of Benevento. Geography The province has an area of 2,071 km2, and, , a total population of 279,308. There are 78 ''comuni'' in the province (for the full list, see comuni of the Province of Benevento).
