Objective. Ageing is one of the risk factors associated with cardiovascular diseases including cardiac arrhythmias and heart failure. Ageing-related dysfunction involves a complicated pathophysiological progress. Abnormal membrane voltage Ca2+ dynamics in aged cardiomyocytes contribute to ageing-related arrhythmias. However, its underlying mechanisms have not been well clarified. Methods. Young old rats or mice were included this study. Cardiac electrophysiological properties functions...
Due to the unique spatiotemporal coupling characteristics in phase, optical vortices have attracted extensive attention. Toroidal vortices, as high-dimensional become a research hotspot recent years due their topological structures. In this paper, we propose an asymmetric grating structure for generation of toroidal compact way. A cylindrical vector wave packet is transformed by into transmitted vortex pulse. Such generator may find applications topology and communications.
Near-infrared spectroscopy (NIRS) has increasingly been used to noninvasively determine hemodynamic concentration change by detecting light intensity changes. The effect of scalp hair follicle (SHF) on NIRS quantification is highlighted since its dark pigmentations a strong absorption source contaminate the signal. Here we have incorporated Monte Carlo modeling for transport in voxelized media, and visible Chinese human with high precision depicting three-dimensional anatomical structures,...
Sorting orbital angular momentum (OAM) of light is crucial for the success optical multiplexing systems. Recently, research on OAM sorting has achieved separation via photonic transformation. Nevertheless, efficiently dense modes in directions still remains challenging. Here, we present a method to implement efficient modes. A hybrid Fresnel lens domain and radial used combination with an multiplier achieve better mode discrimination reduced overlap. The favorable performance demonstrated...
Toroidal vortex, a topological structure commonly observed in nature, exist various types such as bubbles produced by dolphins and the air flow surrounding flying dandelion. A toroidal vortex corresponds to spatiotemporal wave packet shape of donut that propagates direction perpendicular plane ring. In this work, we propose circular asymmetric grating generate rings. cylindrical vector is transformed device into transmitted pulse. Such compact generator may find applications optical topology...
Background: Electrocardiogram (ECG) provides a straightforward and non-invasive approach for various applications, such as disease classification, biometric identification, emotion recognition, so on. In recent years, artificial intelligence (AI) shows excellent performance plays an increasingly important role in electrocardiogram research well. Objective: This study mainly adopts the literature on applications of to focus development process through bibliometric visual knowledge graph...
The spiral transformation has attracted an increasing interest in switching orbital angular momentum (OAM) modes. However, the efficiency is deteriorated by inevitable gap between turns of strips. In order to overcome problem, a multiple-ring conformal mapping scheme proposed for efficient multiplication OAM light. mode at input plane divided into concentric rings, which are mapped multiple sectors and connected ring output plane. This point-to-point mechanism can avoid generation high-order...
To investigate the effect of sevoflurane on tissue permeability lung ischemia-reperfusion injury (LIRI) in rats.A total 45 wistar rats were randomly divided into 3 groups I, II, III. Modified Eppinger method was adopted to establish rat model. Group I served as control group, group III ischemia reperfusion group. Blood gas index, index (LPI) change, pathology change and water content observed compared between at different time points.During reperfusion, all kept balance MAP during points,...
Abstract Background and Study Objective Cranioplasty after microvascular decompression (MVD) is important for preventing postoperative complications such as headache. Autologous particulate bone a common material cranioplasty. The purpose of this study was to evaluate the effect using autologous reconstruct cranial defect produced by MVD. Patients Methods Data were collected from January 2013 December 2016 243 patients who underwent suboccipital retrosigmoidal craniectomy then further...
Monte Carlo simulation is a precise method to model light propagation in bio-tissues and has been considered the golden standard estimate result of other computation methods. But huge burden limited application. In this paper, we propose parallel computing using graphic card accelerate 3-D voxelized media with consideration internal refraction. Optimization mode made by segmentations offered an extra boost speed. The acceleration efficiency affecting factors are investigated rate five...
