The resistive behavior of type-I1 superconductors in the superconducting state is largely influenced by the materials' ability to pin magnetic flux lines. While an externally applied magnetic field leads to an ordered flux-lattice in defect-free superconductors, spatial variatim
D-Pro-Endomorphin-1 and D-Pro-Endomorphin-2, Respectively, Attenuate the Antinociception Induced by Endomorphin-1 and Endomorphin-2 Given Intrathecally in the Mouse
First, the antinociception with the tail-flick test of D-Pro-endomorphin-1 and D-Pro-endomorphin-2 given i.t. was compared with that produced by endomorphin-1 and -2 in male CD-1 mice. High doses of D-Pro-endomorphin-1 (0.2–0.4 pmol) and D-Pro-endomorphin-2 (300–800 pmol) given i
Susceptibility of transcranial electric motor-evoked potentials to varying targeted blood levels of dexmedetomidine during spine surgery.
BACKGROUND Dexmedetomidine has been increasingly used as an adjunct to opioid-propofol total intravenous anesthesia (TIVA). The authors tested the hypothesis and found that clinically relevant blood levels of dexmedetomidine do not produce significant attenuation of the amplitude
Cold Analysis for Dispersion, Attenuation and RF Efficiency Characteristics of a Gyrotron Cavity
In the present paper, a gyrotron cavity is analyzed in the absence of electron beam for dispersion, attenuation and RF efficiency. For all these characteristics, azimuthally symmetric TE0n modes have been considered. The attenuation characteristics for TE0n modes indicated decrea
Colchicine modulates calcium homeostasis and electrical property of HL‐1 cells
Colchicine is a microtubule disruptor that reduces the occurrence of atrial fibrillation (AF) after an operation or ablation. However, knowledge of the effects of colchicine on atrial myocytes is limited. The aim of this study was to determine if colchicine can regulate calcium (
Pre-treatment with Irbesartan attenuates left atrial stunning after electrical cardioversion of atrial fibrillation.
AIMS Left atrial (LA) stunning, the transient impairment of LA function, is responsible for an increased thrombo-embolic risk after cardioversion of atrial fibrillation (AF). Angiotensin receptor blockers (ARBs) attenuate atrial remodelling in AF and could theoretically influence
Electrically tunable hot-silicon terahertz attenuator
We have developed a continuously tunable, broadband terahertz attenuator with a transmission tuning range greater than 10. Attenuation tuning is achieved electrically, by simply changing the DC voltage applied to a heating wire attached to a bulk silicon wafer, which controls its
Design of an active exhaust attenuating valve for internal combustion engines
An active silencer to attenuate internal combustion engine exhaust noise is developed. The silencer consists of an electrically controlled valve connected to a buffer volume. The pulsating flow from the engine is buffered in the volume and the valve resistance is continuously con
A Field Comparison of Fresnel Zone and Ray-Based GPR Attenuation-Difference Tomography for Time-Lapse Imaging of Electrically Anomalous Tracer or Contaminant Plumes
Ground-penetrating radar GPR attenuation-difference tomography is a useful tool for imaging the migration of electrically anomalous tracer or contaminant plumes. Attenuation-difference tomography uses the difference in the trace amplitudes of tomographic data sets collected at di
Chronic intermittent low-level transcutaneous electrical stimulation of auricular branch of vagus nerve improves left ventricular remodeling in conscious dogs with healed myocardial infarction.
BACKGROUND Vagus nerve stimulation attenuates left ventricular (LV) remodeling after myocardial infarction (MI). Our previous study found a noninvasive approach to deliver vagus nerve stimulation by transcutaneous electric stimulation of auricular branch of vagus nerve. So we hyp
