Nature advance online publication 26 October 2014. doi:10.1038/nature13830 Authors: I. Zhuravleva, E. Churazov, A. A. Schekochihin, S. W. Allen, P. Arévalo, A. C. Fabian, W. R. Forman, J. S. Sanders, A. Simionescu, R. Sunyaev, A. Vikhlinin & N. Werner The hot (107 to 108kelvin), ...


Characterizing and predicting the magnetic environment leading to solar eruptions

22-10-2014 | Tahar Amari; Aurélien Canou; Jean-Jacques Aly, Nature, 2014

Characterizing and predicting the magnetic environment leading to solar eruptions Nature 514, 7523 (2014). doi:10.1038/nature13815 Authors: Tahar Amari, Aurélien Canou & Jean-Jacques Aly The physical mechanism responsible for ...


Importance of the DNA "bond" in programmable nanoparticle crystallization [Chemistry]

21-10-2014 | Robert J. Macfarlane; Ryan V. Thaner; Keith A. Brown; Jian Zhang; Byeongdu Lee; SonBinh T. Nguyen; Chad A. Mirkin, Proceedings of the National Academy of Sciences current issue, 2014

If a solution of DNA-coated nanoparticles is allowed to crystallize, the thermodynamic structure can be predicted by a set of structural design rules analogous to Pauling’s rules for ionic crystallization. The details of the crystallization process, however, have proved more difficult to ...


Inner Workings: Roboclam [Inner Workings]

21-10-2014 | Calla Cofield, Proceedings of the National Academy of Sciences current issue, 2014

Digging in the sand might seem like child's play, but doing it efficiently has stumped many adult engineers. As is often the case, nature has revealed a superior solution: this time in the Atlantic razor clam, which can burrow into and out of sandy ocean bottoms more efficiently than man-made,...


Energies, Vol. 7, Pages 6741-6764: Assessment of Energy, Environmental and Economic Performance of a Solar Desiccant Cooling System with Different Collector Types

20-10-2014 | Angrisani, Giovanni ; Roselli, Carlo ; Sasso, Maurizio ; Tariello, Francesco, Energies, 2014

Desiccant-based air handling units can achieve reductions in greenhouse gas emissions and energy savings with respect to conventional air conditioning systems. Benefits are maximized when they interact with renewable energy technologies, such as solar collectors. In this work, experimental tests ...


Real-Time UV-Visible Spectroscopy Analysis of Purple Membrane-Polyacrylamide Film Formation Taking into Account Fano Line Shapes and Scattering

17-10-2014 | María Gomariz et al., PLoS ONE, 2014

by María Gomariz, Salvador Blaya, Pablo Acebal, Luis Carretero We theoretically and experimentally analyze the formation of thick Purple Membrane (PM) polyacrylamide (PA) films by means of optical spectroscopy by considering the absorption of bacteriorhodopsin and scattering. We have applied ...


Energies, Vol. 7, Pages 6401-6411: Experimental Investigation and Discussion on the Mechanical Endurance Limit of Nafion Membrane Used in Proton Exchange Membrane Fuel Cell

09-10-2014 | Xiao, Yang ; Cho, Chongdu, Energies, 2014

As a solution of high efficiency and clean energy, fuel cell technologies, especially proton exchange membrane fuel cell (PEMFC), have caught extensive attention. However, after decades of development, the performances of PEMFCs are far from achieving the target from the Department of Energy ...


Energies, Vol. 7, Pages 6340-6357: New Power Quality Analysis Method Based on Chaos Synchronization and Extension Neural Network

08-10-2014 | Wang, Meng-Hui ; Yau, Her-Terng, Energies, 2014

A hybrid method comprising a chaos synchronization (CS)-based detection scheme and an Extension Neural Network (ENN) classification algorithm is proposed for power quality monitoring and analysis. The new method can detect minor changes in signals of the power systems. Likewise, prominent ...


A Service Brokering and Recommendation Mechanism for Better Selecting Cloud Services

29-08-2014 | Zhipeng Gui et al., PLoS ONE, 2014

by Zhipeng Gui, Chaowei Yang, Jizhe Xia, Qunying Huang, Kai Liu, Zhenlong Li, Manzhu Yu, Min Sun, Nanyin Zhou, Baoxuan Jin Cloud computing is becoming the new generation computing infrastructure, and many cloud vendors provide different types of cloud services. How to choose the best cloud ...


A cellular solution to an information-processing problem [Applied Physical Sciences]

26-08-2014 | Garud Iyengar; Madan Rao, Proceedings of the National Academy of Sciences current issue, 2014

Signaling receptors on the cell surface are mobile and have evolved to efficiently sense and process mechanical or chemical information. We pose the problem of identifying the optimal strategy for placing a collection of distributed and mobile sensors to faithfully estimate a signal that varies ...
