In recent years, the energy consumption of computing systems has increased and a large fraction of this energy is consumed in main memory. Towards this, researchers have proposed use of non-volatile memory, such as phase change memory (PCM), which has low read latency and power; and nearly zero leakage power. However, the write latency and power of PCM are very high and this, along with limited...

In a recent Letter [1], Geiger presents calculations of the dilepton emission from the early stage of ultrarelativistic heavy ion collisions using the parton cascade model (PCM). He shows that the M ⊥ scaling [2] found in Ref. [3] is not observed. In this Comment, we point out that this is largely due to a defect in the PCM. The PCM is based on the perturbative QCD and inevitably contains two i...

UNLABELLED Paracoccidioidomycosis (PCM) is a systemic disease that in its aftermath form is characterized by clinical manifestations related to anatomic or functional sequelae of organs and systems affected during the period of state. AIM To describe the anatomical and functional sequelae in patients with treated laryngeal PCM. MATERIALS AND METHODS Retrospective study. We reviewed the char...

In this paper, we take a new look at the possibilistic c-means (PCM) and adaptive PCM (APCM) clustering algorithms from the perspective of uncertainty. This new perspective offers us insights into the clustering process, and also provides us greater degree of flexibility. We analyze the clustering behavior of PCM-based algorithms and introduce parameters σv and α to characterize uncertainty of ...

Paracoccidioidomycosis (PCM) is a granulomatous disease caused by the dimorphic fungus Paracoccidioides brasiliensis. The immunoglobulin classes and isotypes of antibodies directed to acidic glycosphingolipids (GSLs) and glucosylceramide of P. brasiliensis were determined by enzyme-linked immunosorbent assay of sera from 31 PCM patients. The reactivities of 38 serum samples were analyzed by con...

The mobilized thermal energy storage system (M-TES) has been demonstrated as a promising technology to supply heat using waste heat in industries to distributed users, where heat discharging determines whether M-TES system can satisfy the required heating rate. The objective of this work is to investigate the solidification mechanism of phase change materials (PCM) for heat discharging in a dir...

Simple, accurate, precise and sensitive ultraviolet spectrophotometric and reversed-phase high-performance liquid chromatographic (RPHPLC) methods for simultaneous estimation of paracetamol (PCM) and nabumetone (NAB) in combined tablet dosage form have been developed and validated. Linearity of PCM and NAB was found in concentration range of 2-30 and 1-12 μg/mL in methanol at 249 and 230 nm, re...

Modern servers require large main memories, which so far have been enabled by increasing DRAM’s density. With DRAM’s scalability nearing its limit, PhaseChange Memory (PCM) is being considered as an alternative technology. PCM is denser, more scalable, and consumes lower idle power than DRAM, while exhibiting byte-addressability and access times in the nanosecond range. Still, PCM is slower tha...
