A strict orthogonal drawing of a graph G = (V,E) in R is a drawing of G such that each vertex is mapped to a distinct point and each edge is mapped to a horizontal or vertical line segment. A graph G is HV -restricted if each of its edges is assigned a horizontal or vertical orientation. A strict orthogonal drawing of an HV -restricted graph G is good if it is planar and respects the edge orien...

The voltage sensor domain (VSD) is the key module for voltage sensing in voltage-gated ion channels and voltage-sensing phosphatases. Structurally, both the VSD and the recently discovered voltage-gated proton channels (Hv channels) voltage sensor only protein (VSOP) and Hv1 contain four transmembrane segments. The fourth transmembrane segment (S4) of Hv channels contains three periodically ali...

AIM Ventilation with pure oxygen (hyperoxic ventilation: HV) is thought to decrease whole body oxygen consumption (VO(2)). However, the validity and impact of this phenomenon remain ambiguous; until now, under hyperoxic conditions, VO(2) has only been determined by the reverse Fick principle, a method with inherent methodological problems. The goal of this study was to determine changes of VO(2...

BACKGROUND Altered hypothalamus-pituitary-adrenal (HPA) axis function and reduced hippocampal volume (HV) are established correlates of stress vulnerability. We have previously shown an attenuated cortisol awakening response (CAR) and associations with HV specifically in male first-episode psychosis patients. Findings in individuals at ultra-high risk (UHR) for psychosis regarding these neurobi...

This review summarizes evidence in humans for an association between hyperventilation (HV)-induced hypocapnia and a reduction in cerebral perfusion leading to syncope defined as transient loss of consciousness (TLOC). The cerebral vasculature is sensitive to changes in both the arterial carbon dioxide (PaCO2) and oxygen (PaO2) partial pressures so that hypercapnia/hypoxia increases and hypocapn...

Hydroa vacciniforme (HV) is a photosensitivity disorder in childhood characterized by recurrent vacciniform vesicles, necrotic ulcers, and scars on sun-exposed areas. HV-like lymphoma is a rare variant of cutaneous T-cell lymphoma. HV, atypical HV and HV-like lymphoma belong to the spectrum of Epstein-Barr virus (EBV)-associated lymphoproliferative disorders. We report a fatal case of HV-like l...

This paper presents a new technique for accurately modeling uni-directional High-Voltage lightly-doped-drain MOS (HV MOS) devices by extending the bi-directional HV MOS model and adopting a new parameter extraction method. We have already reported on a SPICE model for bi-directional HV MOS devices based on BSIM3v3. However, if we apply this bi-directional HV MOS model and its parameter extracti...

(2) HV def = −∂ x + V (x), on R, or on [0,∞) with Dirichlet or Neumann boundary conditions. The resonances or scattering poles of HV are defined as the poles of the meromorphic continuation of the resolvent, RV (λ) = (HV − λ ), from Imλ > 0, to C. Except for the poles at λ for which λ are eigenvalues of HV , RV (λ) is bounded on L 2 for Imλ > 0. Its Schwartz kernel, that is the Green function, ...

Introduction A high-voltage (HV) electrical short circuit can be a critical electrical failure in an implantable cardioverter-defibrillator (ICD) system because of the failed delivery of appropriate shocks against fatal arrhythmia. The Food and Drug Administration has classified the St Jude Medical Riata family of ICD leads (St Jude Medical, St Paul, MN) as a class I recall since 2011 because o...

Accurate CCD observations of three Cepheids in the SMC were made with the purpose of confirming their nature of second overtone mode Cepheids. The stars were suspected pulsating in the second overtone mode owing to the unusual light curve and short period reported by Payne-Gaposchkin & Gaposchkin (1966). The analysis of the new data shows that for two stars the previous periods are wrong, and i...
