Distress tolerance (DT) is a proposed transdiagnostic factor in psychopathology, yet sources of individual differences in DT are largely unknown. The present study examined mindfulness and rumination facets as predictors of persistence on a standardized DT task (mirror tracing). Acting with awareness (a facet of mindfulness) and reflection (a potentially adaptive form of rumination) predicted i...

Diffusion tensor MRI (DT-MRI) is an image modality that is gaining clinical importance. After some preliminaries that describe the fundamentals of this imaging modality, we present a new technique to interpolate the diffusion tensor field, preserving boundaries and the constraint of positive-semidefiniteness. Our approach is based on the use of the inverse of the local structure tensor as a met...

IGBT and MOSFET power switches are commonly used in power converters. MOSFET for middle power and IGBT for high power converters : gate drive circuits are used to drive such components. Some applications need to control dv/dt and di/dt from power switches to reduce electromagnetic emissions. New solutions have been introduced and tested since 1990 (conresponding to the maturation of IGBT techno...

Regulatory T (Tregs) cells play an important role in mediating tolerance to self-antigens but can also mediate detrimental tolerance to tumours and pathogens in a Foxp3-dependent manner. Genetic tools exploiting the foxp3 locus including bacterial artificial chromosome- (BAC-) transgenic DEpletion of REGulatory T cells (DEREG) mice have provided essential information on Treg biology and the pot...

Although there are several excellent indexes of myocardial contractility, they require accurate measurement of pressure via left ventricular (LV) catheterization. Here we validate a novel noninvasive contractility index that is dependent only on lumen and wall volume of the LV chamber in patients with normal and compromised LV ejection fraction (LVEF). By analysis of the myocardial chamber as a...

Let i = Es∼di π∗ [eπ̂(s)] for i = 1, 2, . . . , T the expected 0-1 loss at time i of π̂, such that = 1 T ∑T i=1 i. Note that t corresponds to the probability that π̂ makes a mistake under distribution dπ∗ . Let pt represent the probability π̂ hasn’t made a mistake (w.r.t. π∗) in the first tstep, and dt the distribution of state π̂ is in at time t conditioned on the fact it hasn’t made a mistake so f...

Study Design Retrospective cohort study. Objectives Describe the rate of dural tears (DTs) in adult spinal deformity (ASD) surgery. Describe the risk factors for DT and the impact of this complication on clinical outcomes. Methods Patients with ASD undergoing surgery between 2008 and 2014 were separated into DT and non-DT cohorts; demographics, operative details, radiographic, and clinical ...

Since final mitral valve (MV) closure and aortic ejection velocity are mediated by the same forces in early left ventricular (LV) contraction, the rate of final MV closure (BC slope) should reflect LV performance. We first verified whether peak final closing velocity (ds/dt) of the anterior MV leaflet (AMVL) is related to peak aortic ejection velocity (V) and LV dp/dt in 18 open-chest dogs. We ...

DTS-II is a highly diphtheria toxin (DT)-sensitive cell line previously isolated by transfection of wild-type DT-resistant mouse L-M(TK-) cells with the cDNA encoding a monkey Vero cell DT receptor. DTS-II cells are as toxin-sensitive as Vero cells, have approximately 3-fold more receptors than Vero cells, and have approximately 10-fold lower affinity for DT than Vero cells. We now cotransfecte...
