Unified Framework for Finite Element Assembly

At the heart of any finite element simulation is the assembly of matrices and vectors from discrete variational forms. We propose a general interface between problem-specific and general-purpose components of finite element programs. This interface is called Unified Form-assembly Code (UFC). A wide range of finite element problems is covered, including mixed finite elements and discontinuous Galerkin methods. We discuss how the UFC interface enables implementations of variational form evaluation to be independent of mesh and linear algebra components. UFC does not depend on any external libraries, and is released into the public domain

Monitoring of camel milk quality in intensive dairy farm

The implementation of intensive camel dairy farm aiming to put milk and milk products (pasteurized or fermented milk, cheese) on the national market is not possible without a control of the high hygienic quality of the raw matter. In consequence, the daily routine microbiological control is an important step of the milking and milk processing. The present communication is focused on the results after one-year monitoring of milk quality in intensive camel dairy farm, including the control of each milking (morning and afternoon), of mixed milk before and after pasteurization, whey after cheese making and leben. Coliforms and total flora are checked. By applying Good Milking Practices (GMP), the milk quality was improved, the mean coliforms in raw milk decreasing by 3 logs (106 UFC/ml to less than 103 UFC/ml) and the total flora passing from 3.5 x 105 UFC/ml to 1.8 x 104 UFC/ml. Similar trends were observed for processed milk with a significant improvement of the quality. (Résumé d'auteur

The Justice of Unequal Pay in the UFC: An In-Depth Analysis of the Fighters’ Antitrust Class Action Lawsuit Against the UFC and the Misplaced Support of the Proposed Muhammad Ali Expansion Act

In 2016, the Ultimate Fighting Championships (“UFC”) set the record for the largest sale in sports history. The UFC, the primary promotion company of the once fringe sport of mixed martial arts (“MMA”) had matured into a mammoth 4 billion dollar promotion, but not without some growing pains. The league is replete with controversy, mostly dealing with disgruntled athletes over compensation. Athletes of the UFC feel that they are being financially exploited and they may be correct. The athletes are choosing different routes to remedy their pay disparities but they are misguided. The first course of action chosen by the fighters is litigation, as a group of former UFC fighters have filed a class action antitrust suit against the UFC. Fighters are also lobbying for legislation in an attempt to expand the Muhammad Ali Act to regulate MMA as another method of resolution. While both will ultimately fail to appease the aggrieved athletes, the process may injure the UFC brand, something fighters may want to avoid. By reviewing similar antitrust disputes in sports and entertainment, the failure of the lawsuit against the UFC becomes apparent. As for the legislation, the Muhammad Ali Act fell short in protecting fighters in boxing as it was intended and will have the same ineffectualness in MMA. When the UFC was purchased in 2016 by WME-IMG, an immense international entertainment conglomerate, it is not likely the company was ignorant to these unsettled issues. This leads to the conclusion that the league’s prospects are still bright. It is in the fighters’ and the league’s best interests to quell their innate divisive temperaments and negotiate a compromise internally. Part II of this paper discusses the history of MMA, the sport of mixed martial arts. It also evaluates the evolution and current state of the UFC, the premier league that arranges and promotes the competition of elite MMA athletes. After a brief explanation of relevant antitrust laws, Part III analyzes the merits of the class action lawsuit against the UFC. Part IV explores the distinct nature of MMA and why antitrust enforcement will have varying results from what the athletes hope to achieve. Part V addresses possible effects of the proposed federal legislation amending the Muhammad Ali Act. Finally, Part VI summarizes that the antitrust litigation and proposed regulation will fail to redress the fighters’ affliction of their income but may injure the UFC brand. Thus, imploring the league to be proactive in resolving this issue

UFC Fighters Are Taking a Beating Because They are Misclassified as Independent Contractors. An Employee Classification Would Change the Fight Game for the UFC, Its Fighters, and MMA

The current state of affairs in the sport of mixed martial arts (MMA) is overwhelmingly in favor of the companies promoting the fights and not in favor of the athletes actually putting their health and lives at risk. This article looks at the Ultimate Fighting Championship (UFC) and how it classifies its fighters as independent contractors rather than employees, even though it treats the fighters more like employees. This article addresses issues fighters are having with the current classification and then examines how the fighters could be classified as employees. Finally, the article will address what an employee classification would mean for the UFC, its fighters, and MMA in general

Exact dynamics of charge fluctuations in the multichannel interacting resonant level model

A modified version of the spinless Anderson model is studied by means of the continuous-time quantum Monte Carlo method. This study is motivated by the peculiar heavy-fermion behavior observed in certain Samarium compounds, which is insensitive to magnetic field. The model involves M channels for conduction electrons, all of which interact with local f electron via the Coulomb repulsion Ufc, while only one channel has hybridization with the local state. The effective hybridization is reduced by the Anderson orthogonality effect, and a quantum critical point occurs with increasing M and/or increasing Ufc. The numerical results at finite temperature of the local charge susceptibility are well fitted by a simple scaling theory for all M. However, the single-particle spectrum is described by a double Lorentzian for M>1, in contrast with the single Lorentzian with M=1. A quasi-particle perturbation theory is presented that reproduces the quantum critical point for large M. The quasi-particle theory gives not only the renormalized energy scale, but its extrapolation toward higher energies being consistent with the double Lorentzian spectrum.Comment: 10 pages, 10 figure

Superconductivity emerging near quantum critical point of valence transition

The nature of the quantum valence transition is studied in the one-dimensional periodic Anderson model with Coulomb repulsion between f and conduction electrons by the density-matrix renormalization group method. It is found that the first-order valence transition emerges with the quantum critical point and the crossover from the Kondo to the mixed-valence states is strongly stabilized by quantum fluctuation and electron correlation. It is found that the superconducting correlation is developed in the Kondo regime near the sharp valence increase. The origin of the superconductivity is ascribed to the development of the coherent motion of electrons with enhanced valence fluctuation, which results in the enhancement of the charge velocity, but not of the charge compressibility. Statements on the valence transition in connection with Ce metal and Ce compounds are given.Comment: 9 pages, 4 figure

Quantum Critical Phase and Lifshitz Transition in an Extended Periodic Anderson Model

We study the quantum phase transition in $f$-electron systems as a quantum Lifshitz transition driven by selective Mott localization in a realistic extended Anderson lattice model. Using DMFT, we find that a quantum critical {\it phase} with anomalous $\omega/T$ scaling separates a heavy Landau-Fermi liquid from ordered phase(s). Fermi surface reconstruction occurs via the interplay between, and penetration of the Green function zeros to the poles, leading to violation of Luttinger's theorem in the selective-Mott phase . We show how this naturally leads to scale-invariant responses in transport. Our work is represents a specific (DMFT) realization of the hidden-FL and FL$^{*}$ theories, and holds promise for study of "strange" metal phases in quantum matter.Comment: 8 pages,5 figure
