Effects of extraction methods on the composition and molar mass distributions of exopolymeric substances of the bacterium Sinorhizobium meliloti

The influence of the extraction methods on the composition, size diversity, molar mass and size distributions of exopolymeric substances (EPS) from the bacterium Sinorhizobium meliloti wild type (WT) and by the exoY strain deficient in exopolysaccharide pr ...

MATHICSE Technical Report : A quasi-optimal sparse grids procedure for groundwater flows

Fabio Nobile, Lorenzo Tamellini

In this work we explore the extension of the quasi-optimal sparse grids method proposed in our previous work \On the optimal polynomial ap- proximation of stochastic PDEs by Galerkin and Collocation methods" to a Darcy problem where the permeability is mod ...

Long-term mechanical reliability of ceramic thick-film circuits and mechanical sensors under static load

Peter Ryser, Thomas Maeder, Caroline Jacq

In this work, we study the long-term mechanical strength under static load - i.e. static fatigue performance or resistance to subcritical crack growth - of ceramic thick-film circuits, namely how the static fatigue of the substrate is affected by the prese ...

Are there "dragon-kings" events (i.e. genuine outliers) among extreme avalanches?

Christophe Ancey

Predicting the occurrence and spatial extent of extreme avalanches is a longstanding issue. Using field data pooled from various sites within the same mountain range, authors showed that the avalanche size distribution can be described using either an extr ...

Experimental investigation of the low-temperature features of a random Heisenberg spin chain

Joël Mesot, Krunoslav Prsa

Low-dimensional spin systems, consisting of arrays of spins arranged in chains or ladders, have been investigated intensively in recent years using both exactly solvable theoretical models as well as a variety of experimental techniques. In case of random ...

Malachite Green Interferes with Postantibiotic Recovery of Mycobacteria

John McKinney, Neeraj Dhar, Ekaterina Gelman

The genus Mycobacterium comprises slow-growing species with generation times ranging from hours to weeks. The protracted incubation time before colonies appear on solid culture medium can result in overgrowth by faster-growing microorganisms. To prevent co ...

COUP-TFII Controls Mouse Pancreatic beta-Cell Mass through GLP-1-beta-Catenin Signaling Pathways

Anne Grapin-Botton

Background: The control of the functional pancreatic beta-cell mass serves the key homeostatic function of releasing the right amount of insulin to keep blood sugar in the normal range. It is not fully understood though how beta-cell mass is determined. ...

Numerical simulation of microstructure formation during solidification and heat treatments of Ni-base superalloys

Alain Jacot, Charles-André Gandin, Luc Rougier, Paolo Di Napoli

A comprehensive modelling approach has been developed for the simulation of microstructure formation during solidification and heat treatment in Ni-base superalloys. The microsegregation taking place during solidification is simulated using the pseudo-fron ...

Two-Dimensional DDA Contact Constitutive Model for Simulating Rock Fragmentation

Jian Zhao

Due to the difficulties of fracture mechanics in dealing with multicrack problems, the continuum-based numerical methods always encounter mathematical problems when modeling rock fragmentation, so the alternative discontinuum-based numerical approaches are ...

Quality assessment of multidimensional video scalability

Touradj Ebrahimi, Francesca De Simone, Jong Seok Lee

Scalability is a powerful concept for adaptive video content delivery to many end users having heterogeneous and dynamic characteristics of networks and devices. In order to maximize users' quality of experience by selecting appropriate combinations of mul ...
