Effect of Thermal Gradients Created by Electromagnetic Fields on Cell-Membrane Electroporation Probed by Molecular-Dynamics Simulations
(American Physical Society, 2017)The use of nanosecond-duration-pulsed voltages with high-intensity electric fields (∼100 kV/cm) is a promising development with many biomedical applications. Electroporation occurs in this regime, and has been attributed ... -
Particle-in-cell based parameter study of 12-cavity, 12-cathode rising-sun relativistic magnetrons for improved performance
(AIP, 2015)Particle-in-cell simulations are performed to analyze the efficiency, output power and leakage currents in a 12-Cavity, 12-Cathode rising-sun magnetron with diffraction output (MDO). The central goal is to conduct a parameter ... -
Asymmetric conduction in biological nanopores created by high-intensity, nanosecond pulsing: Inference on internal charge lining the membrane based on a model study
(AIP, 2015)Nanosecond, high-intensity electric pulses have been reported to open rectifying pores in biological cell membranes. The present goal is to qualitatively understand and analyze the experimental current-voltage (I-V) data. ... -
Simulation study of HEMT structures with HfO2 cap layer for mitigating inverse piezoelectric effect related device failures
(AIP, 2015)The Inverse Piezoelectric Effect (IPE) is thought to contribute to possible device failure of GaN High Electron Mobility Transistors (HEMTs). Here we focus on a simulation study to probe the possible mitigation of the IPE ... -
Analysis of high field effects on the steady-state current-voltage response of semi-insulating 4H-SiC for photoconductive switch applications
(AIP, 2015)A model-based analysis of the steady-state, current-voltage response of semi-insulating 4H-SiC is carried out to probe the internal mechanisms, focusing on electric field driven effects. Relevant physical processes, such ... -
Examining Elementary Preservice Teachers' Mathematics Common Content Knowledge and Specialized Content Knowledge Related to Base 10 Concepts
(2017-12-14)Despite decades of reforms in mathematics preservice education, content and delivery methods remain mostly the same. Consequently, preservice teachers are entering the teaching profession with a lack of common content and ... -
Switchgrass composition and yield response to alternative soil amendments under intensified heat and drought conditions
(2016)Switchgrass (Panicum virgatum L.) and guinea grass (Panicum maximum Jacq.) have been proposed as sustainable alternatives to fossil fuels in subtropical and tropical environments, respectively; although still requiring ... -
Cover Crop Management on the Southern High Plains: Impacts on Crop Productivity and Soil Water Depletion
(MDPI, 2021)The imminent depletion of the Ogallala Aquifer demands innovative cropping alternatives. Even though the benefits of cover crops are well recognized, adoption has been slow in the Southern High Plains (SHP) of the United ... -
BlocklyXR: An Interactive Extended Reality Toolkit for Digital Storytelling
(MDPI, 2021)Traditional in-app virtual reality (VR)/augmented reality (AR) applications pose a challenge of reaching users due to their dependency on operating systems (Android, iOS). Besides, it is difficult for general users to ... -
Capillary-driven Microfluidic Biosensing Platforms for Digital Biomolecule Detection
(2020-07-30)Microfluidic systems enable rapid diagnosis, screening, and monitoring of diseases and health conditions using small amounts of biological samples and reagents. Research on microfluidic devices for biological analysis has ... -
No acclimation: instantaneous responses to temperature to maintain homeostatic photosynthetic rates under experimental warming across a precipitation gradient in Ulmus americana
(Oxford University Press, 2020)Past research has shown that plants possess the capacity to alter their instantaneous response of photosynthesis to temperature in response to a longer-term change in temperature (i.e. acclimate). This acclimation is ... -
Self-assembly of reversed bilayer vesicles through pnictogen bonding: water-stable supramolecular nanocontainers for organic solvents
(2020)A new air and moisture stable antimony thiolate compound has been prepared that spontaneously forms stable hollow vesicles. Structural data reveals that pnictogen bonding drives the self-assembly of these molecules into a ... -
Desocialization of taxes: A taxation system proposal for Venezuela
(2020)Venezuela requires a change in the economic, fiscal, and political system. Supported on the findings of Acevedo et al. (2020), we argue that the most important challenge is to reduce and starve the government and empower ... -
Model evaluations of multipactor suppression in rectangular waveguides through grooved surfaces and static magnetic field
(2021)Mitigation of multipactor in waveguides is of importance, and strategies have included the addition of external fields, materials engineering, or surface modifications. Here, geometry modifications of rectangular waveguide ... -
Stimulus control of odorant concentration: Pilot study of generalization and discrimination of odor concentration in canines
(MDPI, 2021)Despite dogs’ widespread use as detection systems, little is known about how dogs generalize to variations of an odorant’s concentration. Further, it is unclear whether dogs can be trained to discriminate between similar ... -
Rational irrationality: A two stage decision making model
(Asia University, Taiwan, 2021)This paper proposes a mathematical two-stage decision making model based on dual-decision models from behavioral economics that includes, in addition to cognitive and affective systems, an individualistic human factor ... -
Identification and segmentation of pre-cancerous cervix lesions for automated diagnosis of Cervical Neoplasia
(2007-05)The design and implementation of an automated diagnostic tool for Cervical Intraepithelial Neoplasia (CIN), a detectable and treatable precursor pathology of uterine cervical cancer, is being considered. The pathological ... -
