Designing PhelkStat: Big Data Analytics for System Event Logs
(HICSS Symposium on Cybersecurity Big Data Analytics, 2017-01-04)With wider adoption of micro-service based architectures in cloud and distributed systems, logging and monitoring costs have become increasingly relevant topics of research. There are a large number of log analysis tools ... -
Endothelial cell sensing, restructuring, and invasion in collagen hydrogel structures
(The Royal Society of Chemistry, 2015-09-03)Experimental tools to model cell-tissue interactions will likely lead to new ways to both understand and treat cancer. While the mechanical properties and regulation of invasion have been recently studied for tumor cells, ... -
The impact of sphingosine kinase inhibitor-loaded nanoparticles on bioelectrical and biomechanical properties of cancer cells
(The Royal Society of Chemistry, 2015-11-19)Cancer progression and physiological changes within the cells are accompanied by alterations in the biophysical properties. Therefore, the cell biophysical properties can serve as promising markers for cancer detection and ... -
GC-on-chip: integrated column and photoionization detector
(The Royal Society of Chemistry, 2015-02-04)This paper reports a unique GC-on-chip module comprising a monolithically integrated semi-packed micro separation column (μSC) and a highly sensitive micro helium discharge photoionization detector (μDPID). While semi-packed ... -
Identifying cancer biomarkers by network-constrained support vector machines
(2011-10-12)Background One of the major goals in gene and protein expression profiling of cancer is to identify biomarkers and build classification models for prediction of disease prognosis or treatment response. Many traditional ... -
Transcriptome-wide functional characterization reveals novel relationships among differentially expressed transcripts in developing soybean embryos
(2015-11-14)Background Transcriptomics reveals the existence of transcripts of different coding potential and strand orientation. Alternative splicing (AS) can yield proteins with altered number and types of functional domains, ... -
Knowledge-fused differential dependency network models for detecting significant rewiring in biological networks
(2014-07-24)Modeling biological networks serves as both a major goal and an effective tool of systems biology in studying mechanisms that orchestrate the activities of gene products in cells. Biological networks are context-specific ... -
High-frequency irreversible electroporation (H-FIRE) for non-thermal ablation without muscle contraction
(2011-11-21)Background Therapeutic irreversible electroporation (IRE) is an emerging technology for the non-thermal ablation of tumors. The technique involves delivering a series of unipolar electric pulses to permanently destabilize ... -
SIMAT: GC-SIM-MS data analysis tool
(2015-08-19)Background Gas chromatography coupled with mass spectrometry (GC-MS) is one of the technologies widely used for qualitative and quantitative analysis of small molecules. In particular, GC coupled to single quadrupole MS ... -
A transport-theoretic analysis of pulse propagation through ocean sediments
(Acoustical Society of America, 1982-09-01)The reflection of pulsed acoustic plane waves from ocean sedimentary layers is studied using a stochastic transport theory originally introduced by Barabanenkov et. al. [Izv. Vyssh. Uchebn. Zaved., Radiofiz 15, 1852 (1972)]. ... -
Active suppression of acoustic radiation from impulsively excited structures
(Acoustical Society of America, 1991-12-01)The objective is to use active control to suppress the acoustic energy that is radiated to the far field from a structure that has been excited by a short-duration pulse. The problem is constrained by the assumption that ... -
Acoustic X-wave reflection and transmission at a planar interface: Spectral analysis
(Acoustical Society of America, 2000-01-01)The spectral structure of a three-dimensional X-wave pulse incident on a planar surface of discontinuity is examined. Introducing a novel superposition of azimuthally dependent pulsed plane waves, it is shown for oblique ... -
A Markov process model of ocean sediments
(Acoustical Society of America, 1985-01-01)Monochromatic plane-wave illumination of a randomly stratified, laterally homogeneous sediment layer is considered. The deposition process creating the stochastic layering is assumed to be a continuous parameter, finite ... -
Aperture synthesis of time-limited X waves and analysis of their propagation characteristics
(Acoustical Society of America, 1998-05-01)The feasibility of exciting a localized X-wave pulse from a finite aperture is addressed. Also, the possibility of using a finite-time excitation of a dynamic aperture to generate a finite-energy approximation to an X-wave ... -
Characterization of a nonrigid sphere using the backscattered fields of acoustic X waves
(Acoustical Society of America, 2004-06-01)The scattering of acoustic ultra-wideband X-wave pulses by a nonrigid sphere is simulated for purposes of material identification and characterization. Using the backscattered spectrum of the X-wave pulses, a procedure is ... -
Gaussian decomposition of beams and other functions
(American Institute of Physics, 1989-06-15)The Gabor expansion of a function f_(x) decomposes it into a double sum over integers m and n of a product of basis functions g(x_m X) and Fourier_series exponentials exp(2πi n/X) for given spacing X. The choice of basis ... -
Computer simulation of electron beams. II. Low cost beam current reconstruction
(American Institute of Physics, 1985)Reconstruction of current density in electron beams is complicated by distortion of phase space which can require very fine discretization of the beam into trajectories. An efficient discretization of phase space is ... -
Single-thermal-source formation of Zn x Cd1-x S thin films
(American Institute of Physics, 1979)Thermal sublimation of atomically homogeneous Zn x Cd1_x S powders from a single source results in films that are nonuniform in a direction normal to the substrate. This is attributed to initial preferential sublimation ... -
Computer simulation of electron beams. I. Space charge algorithm for asymmetric beams
(American Institute of Physics, 1985)Longitudinal space_charge forces can be neglected in computer simulations of slowly curving quasilaminar electron beams. A particle mesh type algorithm for transverse space charge forces is developed, and great simplification ...
