The human visual system is spatially inhomogenous, and this property should be included in models of visual processing. We used weighted Hermite polynomials (WHPs) to encode and to characterize such inhomogenous processing. Simulations using an order-transfer-function (OTF) defined for each WHP order, at three spatial scales, provide elegant predictions of variations in two-point resolution and...

This application note defines the ac specifications of voltage feedback operational amplifiers (Op Amps). Directly following these definitions, related amplifier circuits are given where the ramifications of the particular specifications causes less than optimum circuit performance. This is then followed with appropriate circuit solutions.The companion application note for DC specifications alo...

Hair follicle stem cells (HFSCs) have the unique capacity to fuel hair growth throughout lifetime of an organism. During onset new growth, HFSCs get activated and proliferate give rise transit-amplifying that production a follicle. This activation is transient quickly return quiescence. The balance between HFSC quiescence maintained by specific transcriptional landscape. Epigenetic mechanisms a...

The operational model and strategies designed for use in the S. Anna - Research in Advanced Neurorehabilitation Institute for the care and neurorehabilitation of subjects in the vegetative or minimally conscious states are described here. A total of 722 patients were admitted, cared for and discharged from the institute in the period 1998-2009. Application of the model approach has progressivel...
