Phase change materials based on chalcogenides are key enabling technologies for optical storage, such as rewritable CD and DVD, and recently also electrical nonvolatile memory, named phase change memory (PCM). In a PCM, the amorphous or crystalline phase affects the material band structure, hence the device resistance. Although phase transformation is extremely fast and repeatable, the amorphou...

Paracoccidioidomycosis (PCM) or South American Blastomycosis is a systemic fungal infection caused by a dimorphic fungus, Paracoccidioides brasiliensis. It represents the most important systemic mycosis in South America and with higher prevalence among male inhabitants of the rural area. PCM usually affects the lungs, and rarely the intestines. The authors report three cases of PCM, treated at ...

Centrosomes are major microtubule-organizing centers composed of centrioles surrounded by an extensive proteinacious layer called the pericentriolar material (PCM). In C. elegans embryos, the mitotic PCM expands by Polo-kinase (PLK-1) phosphorylation-accelerated assembly of SPD-5 molecules into supramolecular scaffolds. However, how PLK-1 phosphorylation regulates SPD-5 assembly is not known. W...

The impact of frequency selective multipath fading on the bit error rate performance of ARTM Tier-1 waveforms (FQPSK and SOQPSK) is derived and analyzed. In the presence of a strong specular reflection with relative magnitude |Γ1|, the ARTM Tier-1 waveforms suffer a loss in performance of (1−|Γ1|)−4 √ |Γ1| for |Γ1| < 0.5 and a relatively high error floor at approximately 10−2 for |Γ1| ≥ 0.5. Th...

In several multiobjective decision problems Pairwise Comparison Matrices (PCM) are applied to evaluate the decision variants. The problem that arises very often is inconsistency of given PCM. In such a situation it is important to approximate the PCM with a consistent one. The most common way is to minimize the Euclidean distance between the matrices. In the paper we consider minimization of th...

New equations are derived and implemented for efficient and accurate computation of solvation energy derivatives for the conductor-like polarizable continuum model (C-PCM) and the isotropic integral equation formalism polarizable continuum model (IEF-PCM). Two new molecular surface tessellation procedures GEPOL-RT and GEPOL-AS that generate near continuous potential energy surfaces are proposed...

The ultimate goal of Patternless Casting Manufacturing (referred to as PCM) is how to obtain the casts by casting the sand mold directly. In the previous PCM, the resin content of sand mold is much higher than that required by traditional resin sand, so the casts obtained are difficult to be sound and qualified products, which limits the application of this technique greatly. In this paper, the...

Paracoccidioidomycosis (PCM) is an infectious disease, endemic to subtropical areas of Central and South America, caused by the dimorphic fungus Paracoccidioides brasiliensis. It is a chronic disease, mostly affecting adult males, with a mean patient age of 44 years. Central nervous system involvement (CNS PCM) has been found in 13% of the patients with systemic disease. We reviewed the clinica...

The data capacity of aerospace PCM telemetry systems can be greatly improved by the application of data compression techniques, which exploit the redundancy in typical telemetry data. This paper describes the design concept for a compressed PCM (CPCM) telemetry system, and contrasts system design considerations to those involved in development of a conventional PCM system. Simulation results ar...

A thermal energy storage (TES) equipment utilizing phase change material (PCM) was designed and built. The PCM is sealed inside metal tubes and exchanges heat with process fluid flowing outside. The storage capacity characteristics of the system was analyzed based on date covering the inlet and outlet temperatures of the process fluid, volumetric flow rate of the process fluid, and temperature ...
