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 ...

A Biophysical Model of Endocannabinoid-Mediated 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 ...

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 ...

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 ...

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

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

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 ...

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. ...

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, ...

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 n-hexane as process control agent. Milling parameters, with emphasis on milling time and ball size, and conditions were studied ...

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 11-13 weeks of gestation, the risk for ...

Hyaluronan-Derived 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 ...

Lattice free energy with overlap fermions: A two-loop result
(2004)We calculate the two-loop partition function of QCD on the lattice, using the Wilson formulation for gluons and the overlap-Dirac operator for fermions. Direct by-products of our result are the two-loop free energy and ...

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 ...
