Farfield analysis of axially symmetric threedimensional directional cloaks.
(Opt Express, 20130422)Axisymmetric radiating and scattering structures whose rotational invariance is broken by nonaxisymmetric excitations present an important class of problems in electromagnetics. For such problems, a cylindrical ... 
Generalized sampling using a compoundeye imaging system for multidimensional object acquisition.
(Opt Express, 20100830)In this paper, we propose generalized sampling approaches for measuring a multidimensional object using a compact compoundeye imaging system called thin observation module by bound optics (TOMBO). This paper shows the ... 
Global air quality and health cobenefits of mitigating nearterm climate change through methane and black carbon emission controls.
(Environ Health Perspect, 201206)BACKGROUND: Tropospheric ozone and black carbon (BC), a component of fine particulate matter (PM ≤ 2.5 µm in aerodynamic diameter; PM(2.5)), are associated with premature mortality and they disrupt global and regional climate. ... 
Hardsphere crystallization gets rarer with increasing dimension.
(Phys Rev E Stat Nonlin Soft Matter Phys, 200912)We recently found that crystallization of monodisperse hard spheres from the bulk fluid faces a much higher freeenergy barrier in four than in three dimensions at equivalent supersaturation, due to the increased geometrical ... 
High Dimensional Variable Selection with Error Control.
(Biomed Res Int, 2016)Background. The iterative sure independence screening (ISIS) is a popular method in selecting important variables while maintaining most of the informative variables relevant to the outcome in high throughput data. However, ... 
Highly parallel acoustic assembly of microparticles into wellordered colloidal crystallites.
(Soft Matter, 20160121)The precise arrangement of microscopic objects is critical to the development of functional materials and ornately patterned surfaces. Here, we present an acousticsbased method for the rapid arrangement of microscopic particles ... 
Impact of simian immunodeficiency virus infection on chimpanzee population dynamics.
(PLoS Pathog, 20100923)Like human immunodeficiency virus type 1 (HIV1), simian immunodeficiency virus of chimpanzees (SIVcpz) can cause CD4+ T cell loss and premature death. Here, we used molecular surveillance tools and mathematical modeling ... 
Influence of network topology and data collection on network inference.
(Pac Symp Biocomput, 2003)We recently developed an approach for testing the accuracy of network inference algorithms by applying them to biologically realistic simulations with known network topology. Here, we seek to determine the degree to which ... 
Mapping nonlinear receptive field structure in primate retina at single cone resolution.
(eLife, 20151030)The function of a neural circuit is shaped by the computations performed by its interneurons, which in many cases are not easily accessible to experimental investigation. Here, we elucidate the transformation of visual signals ... 
Medical cost trajectories and onsets of cancer and noncancer diseases in US elderly population.
(Comput Math Methods Med, 2011)Time trajectories of medical costsassociated with onset of twelve agingrelated cancer and chronic noncancer diseases were analyzed using the National LongTerm Care Survey data linked to Medicare Service Use files. A special ... 
Modeling endocrine control of the pituitaryovarian axis: androgenic influence and chaotic dynamics.
(Bulletin of mathematical biology, 201401)Mathematical models of the hypothalamuspituitaryovarian axis in women were first developed by Schlosser and Selgrade in 1999, with subsequent models of HarrisClark et al. (Bull. Math. Biol. 65(1):157173, 2003) and Pasteur ... 
Modeling hematopoietic system response caused by chronic exposure to ionizing radiation.
(Radiat Environ Biophys, 201105)A new model of the hematopoietic system response in humans chronically exposed to ionizing radiation describes the dynamics of the hematopoietic stem cell compartment as well as the dynamics of each of the four blood cell ... 
Modeling the evolution of regulatory elements by simultaneous detection and alignment with phylogenetic pair HMMs.
(PLoS Comput Biol, 20101216)The computational detection of regulatory elements in DNA is a difficult but important problem impacting our progress in understanding the complex nature of eukaryotic gene regulation. Attempts to utilize crossspecies ... 
Monte Carlo methods for localization of cones given multielectrode retinal ganglion cell recordings.
(Network (Bristol, England), 201301)It has recently become possible to identify cone photoreceptors in primate retina from multielectrode recordings of ganglion cell spiking driven by visual stimuli of sufficiently high spatial resolution. In this paper we ... 
Neuroprosthetic Decoder Training as Imitation Learning.
(PLoS Comput Biol, 20180202)Neuroprosthetic braincomputer interfaces function via an algorithm which decodes neural activity of the user into movements of an end effector, such as a cursor or robotic arm. In practice, the decoder is often learned ... 
New stochastic carcinogenesis model with covariates: an approach involving intracellular barrier mechanisms.
(Math Biosci, 201203)In this paper we present a new multiplepathway stochastic model of carcinogenesis with potential of predicting individual incidence risks on the basis of biomedical measurements. The model incorporates the concept ... 
Nonlinear oscillator metamaterial model: numerical and experimental verification.
(Opt Express, 20110425)We verify numerically and experimentally the accuracy of an analytical model used to derive the effective nonlinear susceptibilities of a varactorloaded split ring resonator (VLSRR) magnetic medium. For the numerical validation, ... 
Numerical detection of the Gardner transition in a meanfield glass former.
(Phys Rev E Stat Nonlin Soft Matter Phys, 201507)Recent theoretical advances predict the existence, deep into the glass phase, of a novel phase transition, the socalled Gardner transition. This transition is associated with the emergence of a complex free energy landscape ... 
Optimal properties of analog perceptrons with excitatory weights.
(PLoS Comput Biol, 2013)The cerebellum is a brain structure which has been traditionally devoted to supervised learning. According to this theory, plasticity at the Parallel Fiber (PF) to Purkinje Cell (PC) synapses is guided by the Climbing fibers ... 
PenPC: A twostep approach to estimate the skeletons of highdimensional directed acyclic graphs.
(Biometrics, 201603)Estimation of the skeleton of a directed acyclic graph (DAG) is of great importance for understanding the underlying DAG and causal effects can be assessed from the skeleton when the DAG is not identifiable. We propose a ...
