Paraxial Localized Waves in Free Space
(Optical Society of America, 2004-07-01)Subluminal, luminal and superluminal localized wave solutions to the paraxial pulsed beam equation in free space are determined. A clarification is also made to recent work on pulsed beams of arbitrary speed which are ... -
Partial Discharge Analysis under High-Frequency, Fast-Rise Square Wave Voltages in Silicone Gel: A Modeling Approach
(MDPI, 2019-11-28)Wide bandgap (WBG) power modules able to tolerate high voltages and currents are the most promising solution to reduce the size and weight of the power management and conversion systems. These systems are envisioned to be ... -
Passive Detection of Moving Aerial Target Based on Multiple Collaborative GPS Satellites
(MDPI, 2020-01-12)Passive localization is an important part of intelligent surveillance in security and emergency applications. Nowadays, Global Navigation Satellite Systems (GNSSs) have been widely deployed. As a result, the satellite ... -
Paternal malnutrition programs breast cancer risk and tumor metabolism in offspring
(2018-08-30)Background While many studies have shown that maternal factors in pregnancy affect the cancer risk for offspring, few studies have investigated the impact of paternal exposures on their progeny’s risk of this disease. ... -
Patient Derived Xenografts Expand Human Primary Pancreatic Tumor Tissue Availability for ex vivo Irreversible Electroporation Testing
(2020-05-22)New methods of tumor ablation have shown exciting efficacy in pre-clinical models but often demonstrate limited success in the clinic. Due to a lack of quality or quantity in primary malignant tissue specimens, therapeutic ... -
Pattern Expression Nonnegative Matrix Factorization: Algorithm and Applications to Blind Source Separation
(Hindawi, 2008-06-12)Independent component analysis (ICA) is a widely applicable and effective approach in blind source separation (BSS), with limitations that sources are statistically independent. However, more common situation is blind ... -
Performance Analysis of a Mission-Critical Portable LTE System in Targeted RF Interference
Mission-critical wireless networks are being up-graded to 4G long-term evolution (LTE). As opposed to capacity, these networks require very high reliability and security as well as easy deployment and operation in the ... -
Performance Analysis of TaSiOx Inspired Sub-10 nm Energy Efficient In₀.₅₃Ga₀.₄₇As Quantum Well Tri-Gate Technology
(IEEE, 2017-10-24)In this paper, for the first time, the performance analysis of short channel In₀.₅₃Ga₀.₄₇As quantum well (QW) 3-D tri-gate technology with advanced high-κ gate dielectric, TaSiOx is presented. We benchmark the projected ... -
Performance Degradation of Nanofilament Switching Due to Joule Heat Dissipation
(MDPI, 2020-01-09)When a memory cell of a Resistive Random Access Memory (ReRAM) crossbar array is switched repeatedly, a considerable amount of Joule heat is dissipated in the cell, and the heat may spread to neighboring cells that share ... -
Performance Of A Hybrid Bistable Device Using an Acoustooptic Modulator
(Optical Society of America, 1989-08-01)Previous studies on acoustooptic hybrid bistable devices have been limited to the Bragg regime involving two diffracted orders, and no comparisons have been made between experimental results and theoretical predictions. ... -
A (Permalloy + NiZn Ferrite) Moldable Magnetic Composite for Heterogeneous Integration of Power Electronics
(MDPI, 2019-06-22)Soft magnetic moldable composites (SM2Cs) would be ideally suited for the integration of magnetic components in power electronic converters because they can be formed into magnetic cores by low-temperature and ... -
Persistence of upper stratospheric wintertime tracer variability into the Arctic spring and summer
(European Geophysical Union, 2016)Using data from the Aeronomy of Ice in the Mesosphere (AIM) and Aura satellites, we have categorized the interannual variability of winter- and springtime upper stratospheric methane (CH4). We further show the effects of ... -
Persistent photoconductivity in low-energy argon ion-bombarded semi-insulating gaAs
(AIP Publishing, 1991-03-01)Time-dependent phototransport measurements are presented for low-energy argon ion-bombarded semi-insulating liquid-encapsulated Czochralski GaAs. Distinct changes caused by ion beam etching were persistent photoconductivity ... -
Perspectives on Harmful Algal Blooms (HABs) and the Cyberbiosecurity of Freshwater Systems
(Frontiers, 2019-06-04)Harmful Algal Blooms (HABs) have been observed in all 50 states in the U.S., ranging from large freshwater lakes, such as the Great Lakes, to smaller inland lakes, rivers, and reservoirs, as well as marine coastal areas ... -
Phase stitching and error correction in aperture synthesis for generalized phase-shifting interferometry
(Optical Society of America, 2013-07-01)An accurate aperture synthesis method in generalized phase-shifting interferometry is suggested to improve the quality of the reconstructed object wavefront by stitching both the phase and the real amplitude of the object ... -
Phasor measurement units, WAMS, and their applications in protection and control of power systems
