A high-performance 1-7 GHz UWB LNA using standard 0.18 mu m CMOS technology
, 2020 [[abstract]]In this article, we demonstrate a high-peformance 1- to 7-GHz ultra-wideband (UWB) low-noise amplifier (LNA) for UWB system applications implemented in a standard 0.18 mu m CMOS technology. This LNA can also be applied to 1.8/1.9-GHz-band GSM

A novel circular fractal ring UWB monopole antenna with dual band-notched characteristics
ETRI JournalThis paper presents a novel circular fractal ring monopole antenna for ultra-wideband (UWB) hardware with dual band-notched properties. The proposed antenna consists of four crescent-shaped nested rings, a tapered feeding line at the front of the ...

Movement Disorders, EarlyView.Abstract Background Association between monoallelic STUB1 variant and expanded ATXN8OS alleles was recently reported, suggesting a pathogenic interaction that may influence spinocerebellar ataxia type 48 (SCA48) phenotype. Objectives We investigated the frequency and clinical impact of ATXN8OS in a large cohort of STUB1 carriers compared to individuals

Neuroprotection, EarlyView.Long‐term chronic high‐altitude hypobaric hypoxia increases susceptibility to ICH, particularly among migrant populations lacking EPAS1/SENP1 adaptive genetic variants relative to high‐altitude indigenous residents. Persistent hypoxia initiates blood–brain barrier (BBB) breakdown, aberrant glial and immune activation, and progressive neuronal injury ...

Interdiction Models and Heuristics for Graph Propagation
Networks, EarlyView.ABSTRACT Given a graph G=(V,E)$$ G=\left(V,E\right) $$ and a set S⊂V$$ S\subset V $$ of activated/infected nodes, we consider the problem of determining the set of c$$ c $$ nodes that minimizes the network propagation on the subgraph that results from the removal of those c$$ c $$ nodes. To measure network propagation, we assume that a node i$$ i $$ is

Simulation of SOI MOSFETs at GHz frequencies
, 2000 Silicon-on-Insulator (SOI) technology shows advantages over bulk silicon technology at high frequencies. In this work, the performance of SOI MOSFETs has been simulated at GHz frequencies for SOI materials of different substrate resistivities using the ...

A Supervised Learning Framework for Accelerating Solvers and Metaheuristics in Routing Problems
Networks, EarlyView.ABSTRACT Routing problems such as the traveling salesman problem (TSP) and the capacitated vehicle routing problem (CVRP) are computationally challenging due to the exponential growth of their feasible solution spaces with increasing instance size.

Exact Solution of Picker Routing Problems in Zoned Warehouses With Scattered Storage
Networks, EarlyView.ABSTRACT We present two picker routing problems in a warehouse split into multiple disjoint zones with a picker assigned to each zone. Scattered storage is applied, meaning an article can be stored at several pick positions in one or more zones, and capacity restrictions limit the number of collected articles for each picker.
