The newfound relationship between extrachromosomal DNAs and excised signal circles

open access: yesFEBS Letters, EarlyView.
Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

Gaussian process emulators for the undrained bearing capacity of spatially random soils using cell-based smoothed finite element method

open access: yesJournal of Rock Mechanics and Geotechnical Engineering
In this paper, we propose a novel probabilistic method for predicting the undrained bearing capacity of spatially variable soils. Our approach combines a Gaussian process regression (GPR)-based surrogate model with random cell-based smoothed finite ...

Cooperation among Virtual Anthropoids in a Complex Environment [PDF]

open access: yesInterdisciplinary Description of Complex Systems, 2011
This paper presents an agent based model of the evolution of cooperation in a complex environment. Anthropoid agents reproduce sexually, and live in a world where food is irregularly distributed in space and seasonally produced. They can share food, form

The ADaptation and Anticipation Model (ADAM) of sensorimotor synchronization

open access: yesFrontiers in Human Neuroscience, 2013
A constantly changing environment requires precise yet flexible timing of movements. Sensorimotor synchronization (SMS) —the temporal coordination of an action with events in a predictable external rhythm— is a fundamental human skill that contributes to

Electrical and Kinetic Model of an Atmospheric RF Device for Plasma Aerodynamics Applications

open access: yes, 2009
The asymmetrically mounted flat plasma actuator is studied using a self-consistent 2-DIM fluid model at atmospheric pressure. The computational model use the drift-diffusion approximation and a simple plasma phenomenological kinetic model.

Conserved structural motifs in PAS, LOV, and CRY proteins regulate circadian rhythms and are therapeutic targets

open access: yesFEBS Letters, EarlyView.
Cryptochrome and PAS/LOV proteins play intricate roles in circadian clocks where they act as both sensors and mediators of protein–protein interactions. Their ubiquitous presence in signaling networks has positioned them as targets for small‐molecule therapeutics. This review provides a structural introduction to these protein families.

Linking Memories across Time via Neuronal and Dendritic Overlaps in Model Neurons with Active Dendrites

open access: yesCell Reports, 2016
Memories are believed to be stored in distributed neuronal assemblies through activity-induced changes in synaptic and intrinsic properties. However, the specific mechanisms by which different memories become associated or linked remain a mystery.

Cosmic Logic: a Computational Model

open access: yes, 2016
We initiate a formal study of logical inferences in context of the measure problem in cosmology or what we call cosmic logic. We describe a simple computational model of cosmic logic suitable for analysis of, for example, discretized cosmological systems.

Cell wall target fragment discovery using a low‐cost, minimal fragment library

open access: yesFEBS Letters, EarlyView.
LoCoFrag100 is a fragment library made up of 100 different compounds. Similarity between the fragments is minimized and 10 different fragments are mixed into a single cocktail, which is soaked to protein crystals. These crystals are analysed by X‐ray crystallography, revealing the binding modes of the bound fragment ligands.

Postsynaptic signal transduction models for long-term potentiation and depression

open access: yesFrontiers in Computational Neuroscience, 2010
More than a hundred biochemical species, activated by neurotransmitters binding to transmembrane receptors, are important in long-term potentiation and depression.
