On Data Center Demand Response: A Cloud Federation Approach
(IEEE, 2019)The significantly high energy consumption of data centers constitutes a major load on the smart power grid. Data center demand response is a promising solution to incentivize the cloud providers to adapt their consumption ... -
Coupled Mode Analysis for 3D Stress-Free Elastic Acoustic Waveguide
(IEEE, 2019)Acoustic sensors and acoustic measurements receive much attention in various applications. Because waveguides are commonly used in sensor design, theoretical means to study acoustic propagation and interaction in waveguides ... -
Resiliency of Distribution Systems Incorporating Asynchronous Information for System Restoration
(IEEE, 2019)Resiliency of distribution systems under extreme operating conditions is critical, especially when the utility is not available. With the large-scale deployment of distributed resources, it becomes possible to restore ... -
Missing data estimation in fMRI dynamic causal modeling
(Frontiers, 2014-07-04)Dynamic Causal Modeling (DCM) can be used to quantify cognitive function in individuals as effective connectivity. However, ambiguity among subjects in the number and location of discernible active regions prevents all ... -
Design of Introspective Circuits for Analysis of Cell-Level Dis-orientation in Self-Assembled Cellular Systems
(Frontiers, 2016-02-03)This paper discusses a novel approach to managing complexity in a large self-assembled system, by utilizing the self-assembling components themselves to address the complexity. A particular challenge is discussed namely ... -
Identifying Transcriptional Regulatory Modules Among Different Chromatin States in Mouse Neural Stem Cells
(Frontiers, 2019-01-15)Gene expression regulation is a complex process involving the interplay between transcription factors and chromatin states. Significant progress has been made toward understanding the impact of chromatin states on gene ... -
Tumour heterogeneity revealed by unsupervised decomposition of dynamic contrast-enhanced magnetic resonance imaging is associated with underlying gene expression patterns and poor survival in breast cancer patients
(2019-10-17)Abstract Background Heterogeneity is a common finding within tumours. We evaluated the imaging features of tumours based on the decomposition of tumoural dynamic contrast-enhanced ... -
Stimulated Brillouin scattering during electron gyro-harmonic heating at EISCAT
(European Geosciences Union, 2015)Observations of secondary radiation, stimulated electromagnetic emission (SEE), produced during ionospheric modification experiments using ground-based, highpower, high-frequency (HF) radio waves are considered. The High ... -
GPS phase scintillation at high latitudes during geomagnetic storms of 7-17 March 2012-Part 2: Interhemispheric comparison
(European Geosciences Union, 2015)During the ascending phase of solar cycle 24, a series of interplanetary coronal mass ejections (ICMEs) in the period 7-17 March 2012 caused geomagnetic storms that strongly affected high-latitude ionosphere in the Northern ... -
Estimating along-track plasma drift speed from electron density measurements by the three Swarm satellites
(European Geosciences Union, 2015)Plasma convection in the high-latitude ionosphere provides important information about magnetosphere-ionosphere-thermosphere coupling. In this study we estimate the along-track component of plasma convection within and ... -
GPS phase scintillation at high latitudes during geomagnetic storms of 7-17 March 2012-Part 1: The North American sector
(European Geosciences Union, 2015)The interval of geomagnetic storms of 7-17 March 2012 was selected at the Climate and Weather of the Sun-Earth System (CAWSES) II Workshop for group study of space weather effects during the ascending phase of solar cycle ... -
On the relative roles of dynamics and chemistry governing the abundance and diurnal variation of low-latitude thermospheric nitric oxide
(European Geosciences Union, 2019-01-25)We use data from two NASA satellites, the Thermosphere Ionosphere Energetics and Dynamics (TIMED) and the Aeronomy of Ice in the Mesosphere (AIM) satellites, in conjunction with model simulations from the thermosphere-io ... -
Local time extent of magnetopause reconnection using space-ground coordination
(European Geosciences Union, 2019-04-10)Magnetic reconnection can vary considerably in spatial extent. At the Earth's magnetopause, the extent generally corresponds to the extent in local time. The extent has been probed by multiple spacecraft crossing the ... -
Automated Mapping of Typical Cropland Strips in the North China Plain Using Small Unmanned Aircraft Systems (sUAS) Photogrammetry
(MDPI, 2019-10-10)Accurate mapping of agricultural fields is needed for many purposes, including irrigation decisions and cadastral management. This paper is concerned with the automated mapping of cropland strips that are common in the ... -
Piezoelastic PVDF/TPU Nanofibrous Composite Membrane: Fabrication and Characterization
(MDPI, 2019-10-10)Poly (vinylidene fluoride) nanofibers (PVDF NFs) have been extensively used in energy harvesting applications due to their promising piezoresponse characteristics. However, the mechanical properties of the generated fibers ... -
Investigation into State-of-Health Impedance Diagnostic for 26650 4P1S Battery Packs
