We describe a new architecture for passive robots and haptic displays, which we call a programmable constraint machine (PCM). An n-dof PCM can, under computer control, exhibit constraints (smooth, impenetrable virtual surfaces of dimensionality < n), or it can allow free n-dof motion. At the heart of the PCM is a nonholonomic element, which is used as a continuously variable transmission (CVT)....

Phase change memory (PCM) is the best candidate device among next generation random access memory technologies. PCM has a potential to replace Flash memory due to non-volatility and in-place programmability, and low power consumption. Even though lifetime of PCM is longer than flash memory, wear leveling is needed because of non-uniformity of storage workload or malicious attack. In this paper,...

The dot immunobinding assay, a rapid, visually read test, was adapted for serodiagnosis and follow-up of paracoccidioidomycosis (PCM). Purified gp43 antigen was tested before and after sodium metaperiodate treatment. To evaluate the assay, it was tested with sera from PCM, histoplasmosis, Jorge Lobo's disease, aspergillosis, candidiasis, and cryptococcosis patients and healthy subjects. Native ...

We report the identification and primary sequence of PCM-1, a 228-kD centrosomal protein that exhibits a distinct cell cycle-dependent association with the centrosome complex. Immunofluorescence microscopy using antibodies against recombinant PCM-1 demonstrated that PCM-1 is tightly associated with the centrosome complex through G1, S, and a portion of G2. However, late in G2, as cells prepare ...

As a promising nonvolatile memory technology, Phase Change Memory (PCM) has many advantages over traditional DRAM. Multilevel Cell PCM (MLC) has the benefit of increased memory capacity with low fabrication cost. Due to high per-cell write power and long write latency, MLC PCM requires careful power management to ensure write reliability. Unfortunately, existing power management schemes applied...

OBJECTIVES To elucidate the role of the pcm-tolCsm operon in the multidrug resistance of Stenotrophomonas maltophilia. METHODS The presence of the pcm-tolCsm operon was verified by RT-PCR. The phylogenetic relationship between the outer membrane proteins known to be involved in functional tripartite efflux in Escherichia coli, Pseudomonas aeruginosa and S. maltophilia was analysed. The contri...

In C. elegans, genome-wide screens have identified just five essential centriole-duplication factors: SPD-2, ZYG-1, SAS-5, SAS-6, and SAS-4 [1-8]. These proteins are widely believed to comprise a conserved core duplication module [3, 9-14]. In worm embryos, SPD-2 is the most upstream component of this module, and it is also essential for pericentriolar material (PCM) recruitment to the centriol...

The demands of larger memory capacity in high-performance computing systems have motivated the researchers to explore alternatives of DRAM (dynamic random access memory). Since PCM (phase change memory) provides high-density, good scalability and non-volatile data storage, it has received significant amount of attention in recent years. A crucial bottleneck in wide-spread adoption of PCM, howev...

The specification of workloads is required in order to evaluate performance characteristics of application systems using performance prediction approaches like the Palladio Component Model (PCM). One of the biggest challenges in workload modeling is to ensure that the modeled user behavior adequately resembles the real user behavior. However, PCM offers limited support to model such complex use...
