A Variational Approach for Continuous Supply Chain Networks [PDF]
SIAM Journal on Control and Optimization, 2014 We consider a continuous supply chain network consisting of buffering queues and processors first proposed by [D. Armbruster, P. Degond, and C. Ringhofer, SIAM J. Appl. Math., 66 (2006), pp. 896--920] and subsequently analyzed by [D. Armbruster, P. Degond, and C. Ringhofer, Bull. Inst. Math. Acad. Sin. (N.S.), 2 (2007), pp. 433--460] and [D. Armbruster,

Variational theory for a single polyelectrolyte chain revisited [PDF]
The European Physical Journal E, 2004 We reconsider the electrostatic contribution to the persistence length, $\ell_e$, of a single, infinitely long charged polymer in the presence of screening. A Gaussian variational method is employed, taking $\ell_e$ as the only variational parameter. For weakly charged and flexible chains, crumpling occurs at small length scales because conformational ...

Natural variation in the OsbZIP18 promoter contributes to branched-chain amino acid levels in rice.
New Phytologist, 2020 Branched-chain amino acids (BCAAs) are essential amino acids that must be obtained from the diet for humans and animals, and they play important roles in various aspects of plant growth and development.

A Stochastic Decoder for Neural Machine Translation [PDF]
, 2018 The process of translation is ambiguous, in that there are typically many valid trans- lations for a given sentence. This gives rise to significant variation in parallel cor- pora, however, most current models of machine translation do not account for ...

Explicit expanders with cutoff phenomena [PDF]
, 2010 The cutoff phenomenon describes a sharp transition in the convergence of an ergodic finite Markov chain to equilibrium. Of particular interest is understanding this convergence for the simple random walk on a bounded-degree expander graph.

The study of chain link/guide contact in relative alternative translational motion
MATEC Web of Conferences, 2017 The paper presents the study of the chain link/guide contact in relative alternative motion, by performing test and finite elements modeling. According to these, the paper presents the variation of the dynamic friction coefficient at the contact between ...

Quantifying side-chain conformational variations in protein structure [PDF]
Scientific Reports, 2016 AbstractProtein side-chain conformation is closely related to their biological functions. The side-chain prediction is a key step in protein design, protein docking and structure optimization. However, side-chain polymorphism comprehensively exists in protein as various types and has been long overlooked by side-chain prediction.
