Phase change materials (PCM) take advantage of latent heat that can be stored or released from a material over a narrow temperature range. PCM possesses the ability to change their state with a certain temperature range. These materials absorb energy during the heating process as phase change takes place and release energy to the environment in the phase change range during a reverse cooling pr...

Six approaches for downscaling climate model outputs for use in hydrologic simulation were evaluated, with particular emphasis on each method’s ability to produce precipitation and other variables used to drive a macroscale hydrology model applied at much higher spatial resolution than the climate model. Comparisons were made on the basis of a twenty-year retrospective (1975– 1995) climate simu...

Phase-change memory (PCM) has emerged in recent years as the most promising technology for non-volatile memory due to its very high throughput performance and read/write endurance as well as future scalability. Multilevel functionality is crucial for increasing the capacity and thus enhancing the cost per GByte competitiveness of the PCM technology. However, storage of multiple resistance level...

A centrosome consists of two barrel-shaped centrioles embedded in a matrix of proteins known as the pericentriolar material (PCM). The PCM serves as a platform for protein complexes that regulate organelle trafficking, protein degradation and spindle assembly. Perhaps most important for cell division, the PCM concentrates tubulin and serves as the primary organizing centre for microtubules in m...

Phase-change memory (PCM) is a promising technology that is anticipated to be used in the memory hierarchy of future computer systems. However, its access time is relatively slower than DRAM and it has limited endurance cycle. Due to this reason, PCM is being considered as a high-speed storage medium (like swap device) or long-latency memory. In this paper, we adopt PCM as a virtual memory swap...

After frame synchronization, individual measurands are identified according to the frame location. The decommutator identifies and extracts embedded asynchronous data stream (EADS) words. Thus PCM Decommutator is a very crucial subsystem in the satellite data acquisition unit of satellite ground station. A PCM decommutator is designed and implemented on a Stratix FPGA. The Hardware design compr...

PURPOSE To compare mean global cerebral blood flow (CBF) measured by phase-contrast mapping magnetic resonance imaging (PCM MRI) and by 15 O-H2 O positron emission tomography (PET) in healthy subjects. PCM MRI is increasingly being used to measure mean global CBF, but has not been validated in vivo against an accepted reference technique. MATERIALS AND METHODS Same-day measurements of CBF by ...

Centrosomes are major microtubule-organizing centers composed of centrioles surrounded by an extensive proteinacious layer called the pericentriolar material (PCM). In Caenorhabditis elegans embryos, the mitotic PCM expands by Polo-like kinase 1 (PLK-1) phosphorylation-accelerated assembly of SPD-5 molecules into supramolecular scaffolds. However, how PLK-1 phosphorylation regulates SPD-5 assem...

Sera from patients with the acute (AF) and chronic (CF) forms of paracoccidioidomycosis (PCM) were tested against Paracoccidioides brasiliensis cell-free antigens by Western blot (immunoblot). The CFA preparation contained components ranging in molecular mass from 18 to 102 kDa. The immunoglobulin G (IgG) reactivity profiles were similar for patients with both forms of the disease, and the 43-k...

Polymer based phase change materials (PCM) for thermal energy storage (TES) applications have gained some attention recently due to their high stability and potential solid transition. Here, we are the first utilize a simple copolymerization strategy static tunability transition temperature (Tt) of polymeric PCM. The between short long side chain polyethylene glycol methacrylate polymers was de...
