Article
Algorithmic mechanisms for reliable crowdsourcing computation under collusion
(2015)We consider a computing system where a master processor assigns a task for execution to worker processors that may collude. We model the workers' decision of whether to comply (compute the task) or not (return a bogus ...

Article
A Biophysical Model of EndocannabinoidMediated Short Term Depression in Hippocampal Inhibition
(2013)Memories are believed to be represented in the synaptic pathways of vastly interconnected networks of neurons. The plasticity of synapses, that is, their strengthening and weakening depending on neuronal activity, is ...

Article
A biophysical model of endocannabinoidmediated short term depression of excitation in hippocampus
(2013)

Article
Coefficient of variation vs. mean interspike interval curves: What do they tell use about the brain?
(2001)A number of models have been produced recently to explain the high variability of natural spike trains (Softky and Koch, J. Neurosci. 13 (1) (1993) 334). These models use a range of different biological mechanisms including ...

Article
Coevolution of solid stress and interstitial fluid pressure in tumors during progression: Implications for vascular collapse
(2013)The stress harbored by the solid phase of tumors is known as solid stress. Solid stress can be either applied externally by the surrounding normal tissue or induced by the tumor itself due to its growth. Fluid pressure is ...

Article
The effect of strain hardening on the dynamic response of human artery segments
(2017)Background: When subjected to timedependent blood pressure, human arteries undergo large deformations, exhibiting mainly nonlinear hyperelastic type of response. The mechanical response of arteries depends on the health ...

Article
Effect of zooming on texture features of ultrasonic images
(2006)Background: Unstable carotid plaques on subjective, visual, assessment using Bmode ultrasound scanning appear as echolucent and heterogeneous. Although previous studies on computer assisted plaque characterisation have ...

Article
Evolution of osmotic pressure in solid tumors
(2014)The mechanical microenvironment of solid tumors includes both fluid and solid stresses. These stresses play a crucial role in cancer progression and treatment and have been analyzed rigorously both mathematically and ...

Article
The evolutionary consequences of interspecific aggression
(2013)Competition has always been a cornerstone of evolutionary biology, and aggression is the predominant form of direct competition in animals, but the evolutionary effects of aggression between species are curiously understudied. ...

Article
Experimental measurements and mathematical modeling towards quantification of brain swelling stress
(2017)Traumatic brain injury results in brain tissue swelling which can be a life threatening condition due to skull confinement. While previous efforts successfully measured the exhibited volume change in brain tissue swelling, ...

Article
Fabrication of nanocrystalline Mg 2Si via ball milling process: Structural studies
(2012)In this work, nanocrystalline Mg 2Si material was fabricated via wet ball milling process using nhexane as process control agent. Milling parameters, with emphasis on milling time and ball size, and conditions were studied ...

Article
First Trimester Noninvasive Prenatal Diagnosis: A Computational Intelligence Approach
(2016)The objective of this study is to examine the potential value of using machine learning techniques such as artificial neural network (ANN) schemes for the noninvasive estimation, at 1113 weeks of gestation, the risk for ...

Article
HyaluronanDerived Swelling of Solid Tumors, the Contribution of Collagen and Cancer Cells, and Implications for Cancer Therapy
(2016)Despite the important role that mechanical forces play in tumor growth and therapy, the contribution of swelling to tumor mechanopathology remains unexplored. Tumors rich in hyaluronan exhibit a highly negative fixed charge ...

Article
Implications of HIV1 M group polymorphisms on integrase inhibitor efficacy and resistance: Genetic and structural in silico analyses
(2009)The extensive polymorphisms among HIV1 subtypes have been implicated in drug resistance development. Integrase inhibitors represent the latest addition to the treatment of HIV1, and their efficacy and resistance patterns ...

Article
In silico assessment of mouththroat effects on regional deposition in the upper tracheobronchial airways
(2018)Regional deposition of inhaled medicines is a valuable metric of effectiveness in drug delivery applications to the lung. In silico methods are now emerging as a valuable tool for the detailed description of localized ...

Article
Lattice free energy with overlap fermions: A twoloop result
(2004)We calculate the twoloop partition function of QCD on the lattice, using the Wilson formulation for gluons and the overlapDirac operator for fermions. Direct byproducts of our result are the twoloop free energy and ...

Article
Mathematical modeling of herpes simplex virus distribution in solid tumors: Implications for cancer gene therapy
(2009)Purpose: Although oncolytic viral vectors show promise for the treatment of various cancers, ineffective initial distribution and propagation throughout the tumor mass often limit the therapeutic response. A mathematical ...

Article
Mathematical modeling of the oxygen storage capacity phenomenon studied by CO pulse transient experiments over Pd/CeO2 catalyst
(2003)A mathematical model has been developed for the first time to study the oxygen storage capacity (OSC) phenomenon by the CO pulse injection technique over a 1 wt% Pd/CeO2 model catalyst in the 500700°C range. A twostep ...
