In South Asian countries, the spread of COVID-19 was not treated seriously until mid-March 2020. Measures similar to those considered in Europe and other developed countries, such as maintaining social distance and lockdowns, were imposed. ...
Understanding the sodium cation conductivity of human epileptic brain tissue [0.03%]
人癫痫脑组织中钠离子传导性的研究

The time-resolved analysis of periodically excited luminescence decays by the phasor method in the presence of time-gating or binning is revisited. Analytical expressions for discrete configurations of square gates are derived, and the locu...
Design and characterization of telecentric f- θ scanning lenses for broadband terahertz frequency systems [0.03%]
宽带太赫兹频段扫描物镜的光学设计与系统标定
Zachery B Harris,Stefan Katletz,Mahmoud E Khani et al.
Zachery B Harris et al.
Telecentric beam scanning using f-θ lenses offers nearly uniform spot size, linear beam displacement, and normal incidence angle over a planar surface. These unique properties allow for the minimization of imaging distortion over a wide fi...
A modified SEIR model applied to the data of COVID-19 spread in Saudi Arabia [0.03%]
适用于沙特阿拉伯COVID-19传播数据的修改SEIR模型

The covid-19 infection rates for a large number of infections collected from a large number of different sites are well defined with a negligible scatter. The simplest invertible iterated map, exponential growth and decay, emerges from coun...
A novel methodology and new concept of SARS-CoV-2 elimination in heating and ventilating air conditioning systems using waste heat recovery [0.03%]
一种新颖的方法和概念：利用余热回收在供暖通风空调系统中消除SARS-CoV-2病毒
Naser Rezaei,Moharram Jafari,Ata Nazari et al.
Naser Rezaei et al.
Heating and ventilation air conditioning systems in hospitals (cleanroom HVAC systems) are used to control the transmission/spreading of airborne diseases such as COVID-19. Air exiting from these systems may contribute to the spreading of c...
