Shock-induced failure of a Riata lead with normal electrical lead parameters and a normal fluoroscopic appearance: A case report

open access: yesJournal of Arrhythmia, 2014
An 81-year-old man was scheduled for an elective implantable cardioverter defibrillator (ICD) generator exchange because of battery depletion. The Atlas™+ DR ICD (St.

Processing and characterization of epitaxial GaAs radiation detectors

open access: yes, 2015
GaAs devices have relatively high atomic numbers (Z=31, 33) and thus extend the X-ray absorption edge beyond that of Si (Z=14) devices. In this study, radiation detectors were processed on GaAs substrates with 110 $\mu\textrm{m}$ - 130 $\mu\textrm{m ...

An Epithelial Ca2+-Sensor Protein is an Alternative to Calmodulin to Compose Functional KCNQ1 Channels

open access: yesCellular Physiology and Biochemistry, 2015
Background/Aims: KCNQ channels transport K+ ions and participate in various cellular functions. The channels directly assemble with auxiliary proteins such as a ubiquitous Ca2+-sensor protein, calmodulin (CaM), to configure the physiological properties ...

Concentration polarization, surface currents, and bulk advection in a microchannel [PDF]

open access: yes, 2014
We present a comprehensive analysis of salt transport and overlimiting currents in a microchannel during concentration polarization. We have carried out full numerical simulations of the coupled Poisson-Nernst-Planck-Stokes problem governing the ...

A Simulation Analysis of Nanofluidic Ion Current Rectification Using a Metal-Dielectric Janus Nanopore Driven by Induced-Charge Electrokinetic Phenomena

open access: yesMicromachines, 2020
We propose herein a unique mechanism of generating tunable surface charges in a metal-dielectric Janus nanopore for the development of nanofluidic ion diode, wherein an uncharged metallic nanochannel is in serial connection with a dielectric nanopore of ...

Measurement of the Charge Collection Efficiency after Heavy Non-Uniform Irradiation in BaBar Silicon Detectors

open access: yes, 2005
We have investigated the depletion voltage changes, the leakage current increase and the charge collection efficiency of a silicon microstrip detector identical to those used in the inner layers of the BaBar Silicon Vertex Tracker (SVT) after heavy non ...

Generic radiation hardened photodiode layouts for deep submicron CMOS image sensor processes [PDF]

open access: yes, 2011
Selected radiation hardened photodiode layouts, manufactured in a deep submicron CMOS Image Sensor technology, are irradiated by 60Co gamma-rays up to 2.2 Mrad(SiO2) and studied in order to identify the most efficient structures and the guidelines ...

Scaling and Modeling of High Temperature 4H-SiC p-i-n Photodiodes

open access: yesIEEE Journal of the Electron Devices Society, 2018
4H-SiC p-i-n photodiodes with various mesa areas (40 000 μm2, 2500 μm2, 1600 μm2, and 400 μm2) have been fabricated. Both C-V and I-V characteristics of the photodiodes have been measured at room temperature, 200 °C ...

A measurement of Lorentz Angle of radiation-hard Pixel Sensors [PDF]

open access: yes, 2000
Silicon pixel detectors developed to meet LHC requirements were tested in a beam at CERN in the framework of the ATLAS collaboration. The experimental behaviour of irradiated and not-irradiated sensors in a magnetic field is discussed. The measurement of

By dawn or dusk—how circadian timing rewrites bacterial infection outcomes

open access: yesFEBS Letters, EarlyView.
The circadian clock shapes immune function, yet its influence on infection outcomes is only beginning to be understood. This review highlights how circadian timing alters host responses to the bacterial pathogens Salmonella enterica, Listeria monocytogenes, and Streptococcus pneumoniae revealing that the effectiveness of immune defense depends not only
