As cardiomyocytes mature, their sarcomeres and Z-band widths increase in length in order for their myofibrils to produce stronger twitch forces during a contraction. In this study, we tested the hypothesis that tensional homeostasis is affected by altering myofibril forces. To assess this hypothesis, neonatal rat cardiomyocytes were cultured on arrays of microposts to measure cellular contracti...

It is well known that the compactly supported wavelets cannot belong to the class C∞(R) ∩ L(R). This is also true for wavelets with exponential decay. We show that one can construct wavelets in the class C∞(R)∩L2(R) that are “almost” of exponential decay and, moreover, they are band-limited. We do this by showing that we can adapt the construction of the Lemarié-Meyer wavelets [LM] that is foun...

If ψ is a BLc wavelet, a Chui-Shi family of redundant tight frames {Ψ(k); k ∈ Z} can be built. Its redundancy is studied through the subspaces of coefficients in l2(Z2). It will be proved that these subspaces converge to zero when ψ is a uniformly continuous wavelet. Also a Whittaker-ShannonKotel’nikov type sampling theorem will be given for discrete vector functions associated to Ψ(k). Even mo...

We consider the problem of restoring randomly distributed sets of missing pixels in band-limited discrete images , and give non-iterative and iterative algorithms capable of error-free restoration. The methods discussed have minimum dimension, that is, the size of the matrices and vectors which appear in the algorithm is determined by the number of unknown pixels. This is a characteristic which...

Electron reflection at an interface is a fundamental quantum transport phenomenon. The most famous electron reflection is the electron→hole Andreev reflection (AR) at a metal/superconductor interface. While AR can be either specular or retro-type, electron→electron reflection is limited to only the specular type. Here we show that electrons can undergo retro-reflection in bilayer graphene (BLG)...

We report three experiments measuring the upper limits, defined as auditory velocity thresholds beyond which listeners are no longer able to perceptually resolve a smooth circular trajectory in various reverberate conditions. These thresholds were measured for white noise, band-limited white noise and band-limited white noise mixed with a pure tone, in different reverberation conditions: acoust...

ABSTRACT Remote sensing techniques have been used to study and track wildfire smoke plume structure evolution; however, knowledge gaps remain because of the limited availability observational datasets aimed at understanding fine-scale fire–atmosphere interactions microphysics. Meteorological radars investigate evolution rise in time space, but highly resolved observations are limited. In this s...
