With the prevalence of multi-core processors and cloud computing, the server consolidation using virtualization has increasingly expanded its territory, and the degree of consolidation has also become higher. As a large number of virtual machines individually require their own disks, the storage capacity of a data center could be exceeded. To address this problem, copy-onwrite storage systems a...

Anodizing is an electrochemical process that converts the metal surface into a decorative, durable, corrosion-resistant, anodic oxide finish. Aluminum is ideally suited to anodizing, although other nonferrous metals, such as magnesium and titanium, also can be anodized. The anodic oxide structure originates from the aluminum substrate and is composed entirely of aluminum oxide. This aluminum ox...

In this work, we develop a method called fragment comparison and the template comparison (FTCOM) for assessing the global quality of protein structural models for targets of medium and hard difficulty (remote homology) produced by structure prediction approaches such as threading or ab initio structure prediction. FTCOM requires the C(alpha) coordinates of full length models and assesses model ...

Using starch as the carbon precursor and different-sized ZnO naoparticles as the hard template, a series of porous carbon materials for electrochemical sensing were prepared. Experiments of scanning electron microscopy, transmission electron microscopy and Nitrogen adsorption-desorption isotherms reveal that the particle size of ZnO has big impacts on the porous morphology and surface area of t...

The generic programming paradigm has exerted great influence on the recent development of C++, e.g., large parts of its standard library [2] are based on generic containers and algorithms. While templates, the language feature of C++ that supports generic programming, have become widely used and well understood in the last years, one aspect of templates has been mostly ignored: template templat...

in comparison to the previous researches, zro2 nanoparticles with higher surface area (85 m2/g) have been synthesized in this research. the as-prepared zro2 nanoparticles by co-precipitation method were characterized with x-ray diffraction (xrd), scanning electron microscopy (sem) and transmission electron microscopy (tem). the surface area of the sample was characterized by bet method. the eff...

The development of low-cost electrode materials with enhanced activity and favorable durability for hydrogen evolution reactions (HERs) is a great challenge. MoS2 an effective electrocatalyst unique layered structure. In addition, aluminosilica shells can not only provide more hydroxyl groups but also improve the catalyst as protective shell. Herein, we have designed hard-template route to synt...

Many optimization problems are fundamentally hard. Essentially, a ‘hard’ problem is one for which we cannot guarantee to find the best solution in a reasonable amount of time. In practice, however, the quest to solve hard problems is not quite so hopeless as this definition suggests. This is due to the use of approximate methods. An approximate method is an algorithm that we use to try to find ...
