Abstract and Applied Analysis, 2014 Let T⊂R be a periodic time scale in shifts δ± with period P∈(t0,∞)T and t0∈T is nonnegative and fixed. By using a multiple fixed point theorem in cones, some criteria are established for the existence and multiplicity of positive solutions in shifts δ ...

FEBS Letters, EarlyView.Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

A finite bidimensional wavelet framework for computer graphics
CLEI Electronic Journal, 2008 A lot of material has been written about wavelet theory. Most of these texts provide an elegant framework from the functional and real analysis point of view.

FEBS Letters, EarlyView.Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Stability implications of delay distribution for first-order and second-order systems [PDF]
, 2009 In application areas, such as biology, physics and engineering, delays arise naturally because of the time it takes for the system to react to internal or external events.

Pseudospectra and stability radii of analytic matrix functions with application to time-delay systems [PDF]
, 2005 Definitions for pseudospectra and stability radii of an analytic matrix function are given, where the structure of the function is exploited. Various perturbation measures are considered and computationally tractable formulae are derived. The results are

AIP Advances, 2017 The convolution of a series of events is often observed for a variety of phenomena such as the oscillation of a string. A photochemical reaction of a molecule is characterized by a time constant, but materials in the real world contain several molecules ...
