Border Basis Schemes
The basic idea of border basis theory is to describe a zero-dimensional ring P/I by an order ideal of terms whose residue classes form a K-vector space basis of P/I. The O-border basis scheme is a scheme that parametrizes all zero-dimensional ideals that have an O-border basis. In general, the …

Weyl Gröbner Basis Cryptosystems
… class of algebraic cryptosystems called Gröbner Basis Cryptosystems. In 1994, Koblitz introduced the Polly Cracker cryptosystem that is based on the theory of Gröbner basis in commutative polynomials rings. The security of this cryptosystem relies on the fact that the computation of Gröbner basis …

The Neuropsychophysiological basis of empathy
Durante muitas décadas a definição de empatia (a capacidade de sintonizar-se com as experiências do outro) tem sido objeto de extenso debate. O conceito de empatia tem sido usado numa diversidade de afirmações. Um aspeto negligenciado da experiência empática, que tem um papel central nas interações …

The Genetic Basis of Obesity
… studies focused on understanding the genetic basis of this complex disorder. To this effect, this thesis summarizes the current knowledge of obesity genetics, including the monogenic, polygenic and epigenetics field. Given the tremendous contribution of animal models, especially mouse models, …

Basis Risk in Variable Annuities
… a comprehensive and practical analysis of basis risk in the U.S. variable annuity market and examines effective fund mapping strategies to mitigate the level of basis risk while controlling for the associated transaction costs. Variable annuities are personal savings and investment products …

Integer Programming With Groebner Basis
Integer Programming problems are difficult to solve. The goal is to find an optimal solution that minimizes cost. With the help of Groebner based algorithms the optimal solution can be found if it exists. The application of the Groebner based algorithm and how it works is the topic of research. The …

Physikalische Hydrogele auf Polyurethan-Basis
Physical hydrogels have gained recent attention as cell substrates, since viscoelasticity or stress relaxation is a powerful parameter in mechanotransduction, which has long been neglected. We designed multi-functional polyurethanes to form physical hydrogels via a unique tunable gelation …

The Cellular Basis for Hearing
Hair cells constitute the cellular basis for hearing. Their primary role is to convert mechanical signal into electrical signal through the ion channels, called ``mechano-electrical transducer (MET) channels'', in the hair bundles of hair cells. Another important function of hair cells is to …

Basis Sets in Galactic Dynamics
… in 1972 by Clutton-Brock, so-called biorthogonal basis sets have become a popular tool in galactic dynamics. They provide a method of solving Poisson's equation that scales linearly with the number of particles in a galaxy or halo simulation, and have also received wide attention in the …

Modelling stochastic multi-curve basis
… on the assumption of deterministic- or constant-basis spreads. This assumption is too simplistic to describe the modern multi-curve environment and serves as the motivation for this work. A stochastic-basis framework, presented by Mercurio and Xie (2012), with one- and two-factor OIS short-rate …

Deep Hedging of basis risk
Basis risk arises when the writer of a contingent claim cannot trade in the underlying asset and must use a correlated proxy asset to hedge the contingent claim. Suppose the proxy asset is not perfectly correlated to the underlying. In that case, there is a risk that the hedge portfolio does not …

An F4-Style Involutive Basis Algorithm
… then give us the solution. Similarly, Gröbner Basis is the “nice form” of nonlinear equation systems that can span all the polynomials in the given ideal [4]. So we can use Gröbner Basis to analyze the solution of a nonlinear equation system.</p> <p>But how to compute a Gröbner Basis? There …
