Morphology and the gradient of a symmetric potential predict gait transitions of dogs
Gaits and gait transitions play a central role in the movement of animals. Symmetry is thought to govern the structure of the nervous system, and constrain the limb motions of quadrupeds. We quantify the symme...

Note on the coefficient of variations of neuronal spike trains
It is known that many neurons in the brain show spike trains with a coefficient of variation (CV) of the interspike times of approximately 1, thus resembling the properties of Poisson spike trains. Computation...

Synapse fits neuron: joint reduction by model inversion
In this paper, we introduce a novel simplification method for dealing with physical systems that can be thought to consist of two subsystems connected in series, such as a neuron and a synapse. The aim of our ...

A spiking neural network model of the midbrain superior colliculus that generates saccadic motor commands
Single-unit recordings suggest that the midbrain superior colliculus (SC) acts as an optimal controller for saccadic gaze shifts. The SC is proposed to be the site within the visuomotor system where the nonlin...

Retrieving challenging vessel connections in retinal images by line co-occurrence statistics
Natural images contain often curvilinear structures, which might be disconnected, or partly occluded. Recovering the missing connection of disconnected structures is an open issue and needs appropriate geometr...

Bioinspired magnetic reception and multimodal sensing
Several animals use Earth’s magnetic field in concert with other sensor modes to accomplish navigational tasks ranging from local homing to continental scale migration. However, despite extensive research, ani...

Limited capacity of working memory in unihemispheric random walks implies conceivable slow dispersal
Phenomenologically inspired by dolphins’ unihemispheric sleep, we introduce a minimal model for random walks with physiological memory. The physiological memory consists of long-term memory which includes unco...

Thermodynamic DFT analysis of natural gas
Density functional theory was performed for thermodynamic predictions on natural gas, whose B3LYP/6–311++G(d,p), B3LYP/6–31+G(d), CBS-QB3, G3, and G4 methods were applied. Additionally, we carried out thermodynam...

Tuning the electronic and optical properties of NDT-based conjugated polymers by adopting fused heterocycles as acceptor units: a theoretical study
Donor–acceptor conjugated polymers have been successfully applied in bulk heterojunction solar cell devices. Tuning their donor and acceptor units allows the design of new polymers with desired electronic and ...

Automated 3-D Detection of Dendritic Spines from In Vivo Two-Photon Image Stacks
Despite the significant advances in the development of automated image analysis algorithms for the detection and extraction of neuronal structures, current software tools still have numerous limitations when i...

The DFT-NEGF scrutiny of doped fullerene junctions
Using the smallest non-classical fullerene, we investigate the impact of doping at the molecule–electrode interface on the electron transport of molecular junctions. This is accomplished by employing the densi...

Estimating Phred scores of Illumina base calls by logistic regression and sparse modeling
Phred quality scores are essential for downstream DNA analysis such as SNP detection and DNA assembly. Thus a valid model to define them is indispensable for any base-calling software. Recently, we developed t...
