Dayside Magnetospheric and Ionospheric Responses to a Foreshock Transient on 25 June 2008: 1. FLR Observed by Satellite and Ground-Based Magnetometers
(2018-08)As one type of driver of magnetospheric Alfven waves, foreshock transients have received less attention than, for example, the Kelvin-Helmholtz instability, discrete and broadband frequency solar wind dynamic pressure ... -
Modeling Amateur Radio Soundings of the Ionospheric Response to the 2017 Great American Eclipse
(2018-05-28)On 21 August 2017, a total solar eclipse traversed the continental United States and caused large-scale changes in ionospheric densities. These were detected as changes in medium-and high-frequency radio propagation by the ... -
Derivation of Hemispheric Ionospheric Current Functions From Ground-Level Magnetic Fields
(2019-04)The horizontal currents in the high-latitude ionosphere are the primary driver of the magnetic field perturbations that are observed at the surface of the Earth. These currents and their ground effects are an important ... -
Electromagnetic Signal Classification Based on Deep Sparse Capsule Networks
(IEEE, 2019)In complex electromagnetic environments, electromagnetic signal classification rates are low as long time have to be the cost to extract features. To cope with the issue, in this paper, an electromagnetic signal classification ... -
The Mobile Base Station Strategy for Wireless Networks With Successive Interference Cancellation
(IEEE, 2019)Successive interference cancellation (SIC) and mobile base stations (MBSs) have been separately exploited to effectively collect data in wireless networks. This paper aims to jointly optimize SIC and MBSs movement to ... -
Joint Security and QoS Provisioning in Train-Centric CBTC Systems Under Sybil Attacks
(IEEE, 2019)The security and Quality-of-Service (QoS) provisioning are two critical themes in urban rail communication-based train control (CBTC) data communication systems, which can directly affect the train's safe operation. In ... -
An Open Source Modeling Framework for Interdependent Energy-Transportation-Communication Infrastructure in Smart and Connected Communities
(IEEE, 2019)Infrastructure in future smart and connected communities is envisioned as an aggregate of public services, including energy, transportation, and communication systems, all intertwined with each other. The intrinsic ... -
Carrier Frequency Estimation of Time-Frequency Overlapped MASK Signals for Underlay Cognitive Radio Network
(IEEE, 2019)As the single-signal carrier frequency estimation method is unsuitable for the time-frequency overlapped signals in an underlay cognitive radio network (CRN), in this paper, we propose a novel carrier frequency estimation ... -
A Stochastic Optimization Approach for Spectrum Sharing of Radar and LTE Systems
(IEEE, 2019)This paper proposes a chance-constrained stochastic optimization technique that enables effective coexistence between LTE-Unlicensed base stations and radars in a shared spectrum. The optimization problem is formulated to ... -
IEEE 802.11bd & 5G NR V2X: Evolution of Radio Access Technologies for V2X Communications
(IEEE, 2019)With the rising interest in autonomous vehicles, developing radio access technologies (RATs) that enable reliable and low-latency vehicular communications has become of paramount importance. Dedicated short-range communications ... -
Connection between Carbon Incorporation and Growth Rate for GaN Epitaxial Layers Prepared by OMVPE
(MDPI, 2019-08-01)Carbon, a compensator in GaN, is an inherent part of the organometallic vapor phase epitaxy (OMVPE) environment due to the use of organometallic sources. In this study, the impact of growth conditions are explored on the ... -
Application of Sapphire-Fiber-Bragg-Grating-Based Multi-Point Temperature Sensor in Boilers at a Commercial Power Plant
(MDPI, 2019-07-21)Readily available temperature sensing in boilers is necessary to improve efficiencies, minimize downtime, and reduce toxic emissions for a power plant. The current techniques are typically deployed as a single-point ... -
A Master/Slave Approach to Power Flow and Overvoltage Control in Low-Voltage Microgrids
(MDPI, 2019-07-18)This paper proposes a technique to control distributed energy resources in low-voltage microgrids aiming at (i) allowing power flow control at the point of connection with the upstream grid, (ii) keeping voltage profiles ... -
Wearable Accelerometer and sEMG-Based Upper Limb BSN for Tele-Rehabilitation
(MDPI, 2019-07-12)Assessment of human locomotion using wearable sensors is an efficient way of getting useful information about human health status, and determining human locomotion abnormalities. Wearable sensors do not only provide the ... -
COREMIC: a web-tool to search for a niche associated CORE MICrobiome
(PeerJ, 2018-02-15)Microbial diversity on earth is extraordinary, and soils alone harbor thousands of species per, gram of soil. Understanding how this diversity is sorted and selected into habitat niches is a major focus of ecology and ... -
TBAL: Tunnel FET-Based Adiabatic Logic for Energy-Efficient, Ultra-Low Voltage IoT Applications
(IEEE, 2019-01-07)A novel, tunnel field-effect transistor (TFET)-based adiabatic logic (TBAL) circuit topology has been proposed, evaluated and benchmarked with several device architectures (planar MOSFET, FinFET, and TFET) and AL implementations ... -
Recursive Motif Analyses Identify Brain Epigenetic Transcription Regulatory Modules
(Elsevier, 2019-04-09)DNA methylation is an epigenetic modification modulating the structure of DNA molecule and the interactions with its binding proteins. Accumulating large-scale methylation data motivates the development of analytic tools ... -
Asymmetric independence modeling identifies novel gene-environment interactions
(Springer Nature, 2019-02-21)Most genetic or environmental factors work together in determining complex disease risk. Detecting gene-environment interactions may allow us to elucidate novel and targetable molecular mechanisms on how environmental ... -
