A new effective method for speckle noise reduction in ultrasound imaging is introduced in this paper. The proposed method is based on Extra-Energy Reduction (EER) function in the vector field, which is addressed by vector triangular formula. It is reasonable to decide that the calculated the energy of a pixel by vector triangular formula is less than the usual absolute distance energy of the same pixel then the pixel must be noisy. The noisy pixel with higher energy is moved to equilibrium situation by subtracting the extra energy for any type of functional operation (e.g. image segmentation, pattern recognition, objects classification). The implemented method reduces extra-energy from an image and provides a proper gray level distribution into the entire image. The technique demonstrates very impressive noise suppression without loss of important information compared to some existing state-of-the-art speckle denoising methods.

Use of phase-contrast (PC) MRI in assessment of hemodynamics has significant clinical importance. In this paper we develop a novel approach to determination of hemodynamic pressures. 3D gradients of pressure obtained from Navier-Stokes equation are expanded into a series of orthogonal basis functions, and are subsequently projected onto an integrable subspace. Before the projection step however, a scheme is devised to eliminate the discontinuity at the vessel and image boundaries. In terms of the computation time, the proposed approach significantly improves on previous iterative methods for pressure calculations. The method has been validated using computational fluid dynamic simulations and in-vitro MRI studies of stenotic flows.

Tandem mass spectrometry (MS/MS) continues to be the technology of choice for high-throughput analysis of complex proteomics samples. While MS/MS spectra are commonly identified by matching against a database of known protein sequences, the complementary approach of spectral library searching [1,2,3] against collections of reference spectra consistently outperforms sequence-based searches by resulting in significantly more identified spectra. But despite this demonstrated superior sensitivity, the development of methods to determine the statistical significance of Spectrum-Spectrum Matches (SSMs) in peptide spectral library searches is still in its early stages. © 2013 Springer-Verlag.

We present LES simulations of the flow over a wing with sinusoidal leading edge undulations. The undulations act as a passive flow control device, offering superior poststall aerodynamic performance relative to the unmodified wing with the same mean chord. The baseline case of a regular wing is also presented for comparison. In all cases the Reynolds number based on bulk velocity and mean chord is equal to 120, 000, and the angle of attack is set to 20°. The study explores the details of the flow physics and the mechanisms by which the post-stall aerodynamic benefit is gained. For the particular set of geometrical and aerodynamic parameters considered, a hitherto unreported physical mechanism by which the undulation offers their benefit is observed. This increased understanding of the flow physics for the current configuration is an important step towards a more general understanding and the incorporation of the technology into practical designs. Potential applications include vertical axis wind turbines, unmanned air vehicles, helicopter blades, and canard surfaces;the present Reynolds number is of particular relevance to the first two of these applications.

It is often discussed that the fourth methodology for science research is "informatics". The first methodology is a theoretic approach, the second one is observation and/or experiment, and the third one is computer simulation. Informatics is a new methodology for data intensive science, which is a new concept based on the fact that most scientific data are digitalized and the amount of data is huge. The facilities to support informatics are cloud systems. Herein we propose a cloud system especially designed for science. The basic concepts, design, resources, implementation, and applications of the NICT science cloud are discussed.

We have developed finite element modelling techniques to semi-automatically generate personalised biomechanical models of the human left ventricle (LV) based on cardiac magnetic resonance images. Geometric information of the LV throughout the cardiac cycle was derived via semi-automatic segmentation using non-rigid image registration with a pre-segmented image. A reference finite element mechanics model was automatically fitted to the segmented LV endocardial and epicardial surface data at diastasis. Passive and contractile myocardial mechanical properties were then tuned to best match the segmented surface data at end-diastole and end-systole, respectively. Global and regional indices of myocardial mechanics, including muscle fibre stress and extension ratio were then quantified and analysed. This mechanics modelling framework was applied to a healthy human subject and a patient with non-ischaemic heart failure. Comparison of the estimated passive stiffness and maximum activation level between the normal and diseased cases provided some preliminary insight into the changes in myocardial mechanical properties during heart failure. This automated approach enables minimally invasive personalised characterisation of cardiac mechanical function in health and disease. It also has the potential to elucidate the mechanisms of heart failure, and provide new quantitative diagnostic markers and therapeutic strategies for heart failure. © 2013 Springer-Verlag.

Toward a consensus in protein structure nomenclature

Intrinsically disordered proteins 2014年第1期2卷 e970902页

In a recent article, published in , a valuable consensus view regarding the nomenclature for disordered proteins was presented. In this work the authors present a thoughtful and systemic review of terms that have been used in the literature to describe proteins that sample a heterogeneous set of structures during their biological lifetime. We agree that the term "intrinsically disordered proteins" (IDPs) is an appropriate single descriptor to refer to this particular class of proteins, although it does not fully capture much of the nuanced complexities that are inherent to this class. In what follows we suggest a refinement to this nomenclature based on an analysis of the underlying ensemble that describes the thermally accessible states of a given IDP.

Server clustering is a common design principle employed by many organisations who require high availability, scalability and easier management of their infrastructure. Servers are typically clustered according to the service they provide whether it be the application(s) installed, the role of the server or server accessibility for example. In order to optimize performance, manage load and maintain availability, servers may migrate from one cluster group to another making it difficult for server monitoring tools to continuously monitor these dynamically changing groups. Server monitoring tools are usually statically configured and with any change of group membership requires manual reconfiguration, an unreasonable task to undertake on large-scale cloud infrastructures. In this paper we present the Cloudlet Control and Management System (C2MS), a system for monitoring and controlling dynamic groups of physical or virtual servers within cloud infrastructures. The C2MS extends Ganglia - an open source scalable system performance monitoring tool - by allowing system administrators to define, monitor and modify server groups without the need for server reconfiguration. In turn administrators can easily monitor group and individual server metrics on large-scale dynamic cloud infrastructures where roles of servers may change frequently. Furthermore, we complement group monitoring with a control element allowing administrator-specified actions to be performed over servers within service groups as well as introduce further customized monitoring metrics. This paper outlines the design, implementation and evaluation of the C2MS.
