Metabolic Syndrome, Kidney-Related Adiposity, and Kidney Microcirculation: Unraveling the Damage.

Metabolic syndrome (MetS) is a cluster of interrelated risk factors, including insulin resistance, hypertension, dyslipidemia, and visceral adiposity, all of which contribute to kidney microvascular injury and the progression of chronic kidney disease (CKD). However, the specific impact of each component of MetS on kidney microcirculation remains unclear. Given the increasing prevalence of obesity, understanding how visceral fat-particularly fat surrounding the kidneys-affects kidney microcirculation is critical.

Effects of Seed Layer Coating and Oxygen Plasma Treatment on the Growth of ZnO Nanorods for UV Photodetector Applications.

Dark current in optical sensors has been one of their issues. The performance of these sensors can be improved by reducing their dark current. In this study, we investigated UV sensors based on ZnO nanorods (ZNRs), in particular, their current-voltage characteristics, response and recovery times, on-off current ratio, and responsivity as a function of the device process conditions.

Thermal Analysis and Operational Characteristics of an AlGaN/GaN High Electron Mobility Transistor with Copper-Filled Structures: A Simulation Study.

In this study, we investigated the operational characteristics of AlGaN/GaN high electron mobility transistors (HEMTs) by applying the copper-filled trench and via structures for improved heat dissipation. Therefore, we used a basic T-gate HEMT device to construct the thermal structures. To identify the heat flow across the device structure, a thermal conductivity model and the heat transfer properties corresponding to the GaN, SiC, and Cu materials were applied.

Combustible Gas Classification Modeling using Support Vector Machine and Pairing Plot Scheme.

Combustible gases, such as CH and CO, directly or indirectly affect the human body. Thus, leakage detection of combustible gases is essential for various industrial sites and daily life. Many types of gas sensors are used to identify these combustible gases, but since gas sensors generally have low selectivity among gases, coupling issues often arise which adversely affect gas detection accuracy.

Operational Characteristics of Various AlGaN/GaN High Electron Mobility Transistor Structures Concerning Self-Heating Effect.

This study investigated DC characteristics of AlGaN/GaN high electron mobility transistors (HEMTs) considering self-heating effect (SHE) with basic T-gate (BT), drain-side extended T-gate (DSET), and source-bridge FP (SBFP) structures. We analyzed threshold voltage, transconductance, drain saturation current, and breakdown voltage of each structure for device optimization. Experimental data were initially matched with simulated data for the BT structure, then DC characteristics were compared with the drift-diffusion, coupled drift-diffusion and self-heating models for basic T-gate HEMT devices.

DC Characteristics of AlGaN/GaN High-Electron Mobility Transistor with a Bottom Plate Connected to Source-Bridged Field Plate Structure.

We investigate DC characteristics of AlGaN/GaN high-electron mobility transistors by using a source-bridged field plate and additional bottom plate (BP) structure. The analysis of experimental data was performed with a two-dimensional simulator. Source connected BP structure stabilized threshold voltage and transconductance regardless of various drain voltages.
