Microsecond relaxation processes in shear and extensional flows of weakly elastic polymer solutions
, 2012 In this paper, we introduce an experimental protocol to reliably determine extensional relaxation times from capillary thinning experiments of weakly elastic dilute polymer solutions. Relaxation times for polystyrene in diethyl phthalate solutions as low

Electronic conduction in La-based perovskite-type oxides
Science and Technology of Advanced Materials, 2015 A systematic study of La-based perovskite-type oxides from the viewpoint of their electronic conduction properties was performed. LaCo0.5Ni0.5O3±δ was found to be a promising candidate as a replacement for standard metals used in oxide electrodes and ...

Relaxation times of non-Markovian processes [PDF]
Physical Review A, 1987 We consider a general class of non-Markovian processes defined by stochastic differential equations with Ornstein-Uhlenbeck noise. We present a general formalism to evaluate relaxation times associated with correlation functions in the steady state. This formalism is a generalization of a previous approach for Markovian processes.

Recurrent Hypothermia and Autonomic Dysfunction Secondary to Shapiro Syndrome
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT A 44‐year‐old man presented with recurrent hypothermia, diaphoresis and hypertension. Extensive investigation for infectious, inflammatory, metabolic and endocrine aetiologies was negative. MR scan of the brain demonstrated no lesions but revealed callosal dysgenesis, consistent with Shapiro syndrome.

NMR RELAXATION METHODS TO DETECT PROTEIN DYNAMICS: EVALUATION OF ACCURACY, IMPROVEMENT OF THE METHODOLOGY, AND ITS APPLICATION [PDF]
, 2013 Proteins are dynamic molecules whose ability to undergo conformational changes and fluctuations can impact their biological function, such as enzyme catalysis and substrate recognition. Mutations or perturbations that do not significantly change protein

Российский технологический журнал, 2017 The article examines the relaxation processes that occur in an elastic solid medium when it is heated and cooled, especially their influence on the temperature field. Besides, we considered in this paper the heat equation of parabolic type arising in the

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Neurochemical levels measured by brain MR spectroscopy (MRS) have been proposed as endpoints for clinical trials in early‐stage spinocerebellar ataxia (SCA) trials. We tested their trial‐readiness by quantifying neurochemicals in three affected brain regions in early‐stage cohorts of SCA2 and SCA3, examining their reproducibility in ...
