Abstract We study the dynamics of action potentials some electrically excitable cells: neurons and cardiac muscle cells. Bursting, following a fast–slow dynamics, is most characteristic behavior these dynamical systems, number spikes may change due to spike-adding phenomenon. Using analytical numerical methods we give, by focusing on paradigmatic 3D Hindmarsh–Rose neuron model, review recent re...

We present a new approach to digital forensic evidence acquisition and disk imaging called sifting collectors that images only those regions of a disk with expected forensic value. Sifting collectors produce a sector-by-sector, bit-identical AFF v3 image of selected disk regions that can be mounted and is fully compatible with existing forensic tools and methods. In our test cases, they have ac...

Experts have long disagreed over management and measurement of temporomandibular disorders. This article applies critical reasoning to evaluate the different models for dealing with TMD's. Differences over definitions, research methodology and paradigmatic concepts are discussed. Huge deficiencies in the psychosocial model are identified. Validity construct utilizing objective measurement of bi...

The construction and evaluation of scientific models, together with the iterative modification of these models in response to evidence, constitute paradigmatic scientific practices. If inquiry instruction is to engage students in authentic scientific reasoning, these practices need to become routine in the science curriculum. This paper reports on some of the difficulties middle-school students...

Computational neuroscience is dominated by a few paradigmatic models, but it remains an open question whether the existing modelling frameworks are sufficient to explain observed behavioural phenomena in terms of neural implementation. We take learning and synaptic plasticity as an example and point to open questions, such as one-shot learning and acquiring internal representations of the world...

the sudden transfer of guardianship, from husband to wife, causing a string of insecurity and additional duties for women. the phenomenon of woman-headed households is increasing for different reasons in the world. studies indicate that, householder women are facing social and economic challenges and constraints. the aim of this study is pathology of social interactions women-headed households ...
