The aim of this paper is to present a novel platform for advanced transmission of medical image and video, introducing context awareness in telemedicine systems. Proper scalable image and video compression schemes are applied to the content according to environmental properties (i.e., the underlying network status, content type, and the patient status). The transmission of medical images and vi...

This paper presents a new aqueous precipitation method to prepare silicon-substituted hydroxyapatites Ca10(PO4)6-y(SiO4)y(OH)2-y(VOH)y (SiHAs) and details the characterization of powders with varying Si content up to y=1.25molmolSiHA(-1). X-ray diffraction, transmission electron microscopy, solid-state nuclear magnetic resonance and Fourier transform infrared spectroscopy were used to accuratel...

We investigate the amorphous structure, chemical bonding, and electrical properties of magnetron sputtered Fe(1-xCx) (0.21 ⩽ x ⩽ 0.72) thin films. X-ray, electron diffraction and transmission electron microscopy show that the Fe(1-xCx) films are amorphous nanocomposites, consisting of a two-phase domain structure with Fe-rich carbidic FeC(y), and a carbon-rich matrix. Pair distribution function...

PURPOSE The immunoproteasome is a proteasome subtype with a well-characterized role in the immune system. The presence of high immunoproteasome concentrations in the photoreceptors and synaptic regions of the immune-privileged retina implies a role in visual transmission. In this study, immunoproteasome knockout (KO) mice lacking either one (lmp7(-/-), L7) or two (lmp7(-/-)/mecl-1(-/-), L7M1) c...

We study the heat content asymptotics on a Riemannian manifold with smoooth boundary defined by Dirichlet, Neumann, transmittal and transmission boundary conditions. Subject Classification: 58J50

Streaming degradable content (such as video or audio) over a wireless channel presents new challenges to modern digital design, which was founded on the separation theorem of Shannon theory. Joint source-channel coding (JSCC) has recently received increasing interest to address the varying nature of the wireless channel conditions (under mobility or multicast). The conventional approach to JSCC...

An autapse is a synapse between a neuron and itself, a peculiar structure with an unclear function. A new study suggests that excitatory autapses contribute to a positive-feedback loop that maintains persistent electrical activity in neurons.

Cognitive scientists have increasingly turned to cultural transmission to explain the widespread nature of religious representations. One key hypothesis focuses on memory, proposing that that minimally counterintuitive (MCI) content facilitates the transmission of supernatural beliefs. We propose two caveats to the MCI hypothesis: 1) distinctiveness, and therefore memory, decreases as MCI conce...

Transmission is a fundamental step in the life cycle of every parasite but it is also one of the most challenging processes to model and quantify. In most host-parasite models, the transmission process is encapsulated by a single parameter β Many different biological processes and interactions, acting on both hosts and infectious organisms, are subsumed in this single term. There are, however, ...

This paper describes new schemes for video transmission over wireless channels. Traditionally data was segmented using headers and data type (e.g. motion vectors, low and high frequency DCT coefficients). However, for wireless applications that have very low bandwidths available, a finer granularity of control may be essential. We propose content based approaches for further video segmentation....
