The homogeneous shifts

Journal of Functional Analysis, 2003
In the paper under review, firstly, homogeneous operators are introduced. Then, homogeneous scalar weighted operators are characterized and classified completely. The authors show that all irreducible homogeneous operators are block shifts.

Structural and biochemical insights into the thermostable esterase Ta0887 from Thermoplasma acidophilum

FEBS Open Bio, EarlyView.
In this study, a novel esterase from the thermoacidophilic archaeon Thermoplasma acidophilum was biochemically and structurally characterized. Our results demonstrate that Ta0887 is a highly thermostable esterase that preferentially hydrolyzes p‐nitrophenyl hexanoate and possesses an α‐helical cap domain that likely contributes to its substrate ...

Mixing and Segregation in Powders: Evaluation, Mechanisms and Processes

KONA Powder and Particle Journal, 2014
Mixing in powders generally results from relative motion of groups of particles – convective mixing – or of individuals – diffusive mixing. Segregation or demixing occurs when the motion of individual particles

Characterization of the key membrane protein cytochrome Cyc2 from Ghiorsea bivora

FEBS Open Bio, EarlyView.
This study reports the first detailed biochemical analysis of Cyc2TAG1_1, a cytochrome protein involved in microbial iron oxidation. We produced and purified this enzyme in E. coli, then measured its iron‐oxidizing efficiency, and characterized its electrical and structural properties.

Persuasion: Reflections on Economics, Data and the 'Homogeneity Assumption' [PDF]

This paper discusses issues to do with the empirical basis of modern economics and points towards the need to look more closely at the ‘homogeneity assumption’ that underpins much economic theory.

Controlling Effect of Seepage Channels in Tight Reservoirs on Fluid Flow Capacity Based on Pore–Throat Network Numerical Simulation and Fluid Injection Experiments

Energies
Micron-scale pores and their connecting throats govern fluid transport in tight reservoirs, yet seepage channel differences among lithologies remain poorly quantified.

Investigation of uniformity in pig carcass and meat quality traits

Animal, 2010
The study was carried out to provide information on uniformity of commercial pigs on some of the most important traits determining pork quality: carcass, loin, ham and shoulder weights, fatness, drip loss, pH and colour.

Understanding Further the Phenotypic Spectrum of Central Nervous System Inflammatory Demyelinating Disorders Using Unsupervised Clustering

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Central nervous system (CNS) inflammatory demyelinating syndromes, including multiple sclerosis (MS), aquaporin‐4 antibody–positive neuromyelitis optica spectrum disorder (AQP4 + NMOSD), and myelin oligodendrocyte glycoprotein (MOG) antibody–associated disease (MOGAD), occasionally overlap.

Comparison of objective measures for predicting perceptual balance and visual aesthetic preference

Frontiers in Psychology, 2016
The aesthetic appreciation of a picture largely depends on the perceptual balance of its elements. The underlying mental mechanisms of this relation, however, are still poorly understood.

Dimethyl Fumarate, But Not Rituximab, Reduces Serum GFAP Levels and PIRMA in Relapsing–Remitting MS

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Serum neurofilament light chain (sNfL) and glial fibrillary acidic protein (sGFAP) levels are believed to reflect mainly acute and chronic disease processes in multiple sclerosis (MS), respectively. In this study, we investigated whether dimethyl fumarate (DMF) and rituximab (RTX) differentially affect these biomarkers.
