The Wilson fermion determinant can be written as product of the determinants of two hermitian positive definite matrices. This formulation allows to simulate non-degenerate quark flavors by means of the hybrid Monte Carlo algorithm. A major numerical difficulty is the occurrence of nested inversions. We construct a Uzawa iteration scheme which treats the nested system within one iterative process.

Transformation of nested SQL queries into join queries is advantageous because a nestedSQL query can be looked upon as a nested-loop join, which is just one of the several joinimplementations that may be available in a relational DBMS. In join queries, dangling(unmatched) operand tuples are lost, which causes a problem in transforming nestedqueries having the aggregate funct...

Abstract The nested distance builds on the Wasserstein to quantify difference of stochastic processes, including also evolution information modelled by filtrations. Sinkhorn divergence is a relaxation distance, which can be computed considerably faster. For this reason we employ and take advantage related (fixed point) iteration algorithm. Furthermore, investigate transition entropy throughout ...

The order in which the variables of a linear system are processed determines the total amounts of fill and work to perform LU decomposition on the system. We identify a trade-off between the amounts of fill and work for a given order and the parallelism inherent in that order. We present two algorithms: one that tries to parallelize sequential orders, and another that tries to produce low-fill ...

Background and Aims: Canine distemper (CD) is a deadly infectious disease of Canidae family. CD is a multi-systemic viral disease and is specified by wide range of clinical symptoms. The manifestations are not always indicative of CD, therefore a laboratory confirmation is necessary for suspected cases. Materials and Methods: Different clinical specimens of 19 CD suspected unvaccinated dogs wer...

We model the Fermi surface of the cuprates by one-dimensional nested parts near (0, pi) and (pi, 0) and unnested parts near the zone diagonals. Fermions in the nested regions form 1D spin liquids and develop spectral gaps below some approximately T*, but superconducting order is prevented by 1D phase fluctuations. We show that the Josephson coupling between these order parameters locks their re...

This paper describes a multi-perspective software visualization environment, SHriMP, which combines single view and multi-view techniques to support software exploration at both the architectural and source code levels. SHriMP provides three different views: a primary nested view and two subsidiary views. The primary nested view employs fisheye views of nested graphs, provides contextual cues, ...

We provide the first behavioral characterization of nested logit, a foundational and widely applied discrete-choice model, through introduction nonparametric version logit that we call “nested stochastic choice” (NSC). NSC is characterized by single axiom weakens independence irrelevant alternatives on basis revealed similarity to allow for effect. Nested an additional menu-independence axiom. ...
