Mathematical modeling and dynamics of immunological exhaustion caused by measles transmissibility interaction with HIV host.

This paper mainly addressed the study of the transmission dynamics of infectious diseases and analysed the effect of two different types of viruses simultaneously that cause immunodeficiency in the host. The two infectious diseases that often spread in the populace are HIV and measles. The interaction between measles and HIV can cause severe illness and even fatal patient cases.

Design and Simulation of Efficient SnS-Based Solar Cell Using Spiro-OMeTAD as Hole Transport Layer.

In the present paper, the theoretical investigation of the device structure ITO/CeO/SnS/Spiro-OMeTAD/Mo of SnS-based solar cell has been performed. The aim of this work is to examine how the Spiro-OMeTAD HTL affects the performance of SnS-based heterostructure solar cell. Using SCAPS-1D simulation software, various parameters of SnS-based solar cell such as work function, series and shunt resistance and working temperature have been investigated.

Numerical Study to Enhance the Sensitivity of a Surface Plasmon Resonance Sensor with BlueP/WS-Covered AlO-Nickel Nanofilms.

In the traditional surface plasmon resonance sensor, the sensitivity is calculated by the usage of angular interrogation. The proposed surface plasmon resonance (SPR) sensor uses a diamagnetic material (AlO), nickel (Ni), and two-dimensional (2D) BlueP/WS (blue phosphorous-tungsten di-sulfide). The AlO sheet is sandwiched between silver (Ag) and nickel (Ni) films in the Kretschmann configuration.

Vibration analysis of nanobeams subjected to gradient-type heating due to a static magnetic field under the theory of nonlocal elasticity.

Nanoelectromechanical systems (NEMS) have received great interest from researchers around the world since the advent of nanotechnology and nanoengineering. This can be attributed due to the unique characteristics of NEMS devices and their wide range of applications. Among these applications, nanobeams and nanotubes now have an important role in the design of a variety of NEMS engineering devices.

Assessing the pre-hospital care preparedness to face mass casualty incident in Saudi Arabia in 2017-2018.

To assess the mass casualty incident (MCI) preparedness of pre-hospital care providers in Saudi Arabia and to identify and highlight their strengths and weaknesses when responding to MCIs.  Methods: This cross-sectional descriptive quantitative analysis was conducted between January 2017 and 2018 and included all Saudi Red Crescent Authority (SRCA) general administration branches in 13 regions in Saudi Arabia. The modified version of the emergency medical specialists (EMS) incident response and readiness assessment (EIRRA) tool was used in this study.

Imaging photonic crystals using hemispherical digital condensers and phase-recovery techniques.

We describe experiments where Fourier ptychographic microscopy (FPM) and dual-space microscopy (DSM) are implemented for imaging photonic crystals using a hemispherical digital condenser (HDC). Phase-recovery imaging simulations show that both techniques should be able to image photonic crystals with a period below the Rayleigh resolution limit. However, after processing the experimental images using both phase-recovery algorithms, we found that DSM can, but FPM cannot, image periodic structures with a period below the diffraction limit.

Illumination-direction multiplexing Fourier ptychographic microscopy using hemispherical digital condensers.

Simulations were conducted to explore a broader collection of possible illumination patterns realizable using a white-light-emitting hemispherical digital condenser. Several simple, but practical, illumination patterns were selected and used in experiments where a sample was illuminated simultaneously from different directions. The illumination-direction multiplexing (IDM) Fourier ptychographic microscopy (FPM) method was successfully used for imaging and phase recovery.
