A Pilot Study on Evaluating Recovery of the Post-Operative Based on Acceleration and sEMG

Although abdominal operation is a kind of important clinical surgery, recovery of the post-operative is usually evaluated by the judgment of doctors. This traditional medical care mode may take much time of medical staffs and meanwhile increase the expense of patients. In this paper, a recovery evaluation system is established for the abdominal post-operative by using body sensor networks (BSN). The evaluation system can collect acceleration signals from five parts of human body and surface electro myographic (sEMG)signals from abdomen muscle group (AMG) during a user’sdaily activities. An experiment as a pilot study has been conducted to test the validity and feasibility of the system. The experimental results showed the evaluation system may effectively acquire the relationship between a user’s daily activities and intensity of AMG. The study work in this paper may be used as a basis for further study on evaluating recovery level of the actual post-operative.
A Column Generation Approach for Spectrum Allocation in Cognitive Wireless Mesh Network

Cognitive radio (CR) has the potential to substantially improve the system capacity and adaptability of wireless mesh network (WMN). In this paper we investigate the achievable performance gain of cognitive wireless mesh network (CWMN), in which all nodes are equipped with CRs, by jointly optimizing spectrum allocation, routing and time scheduling. The formulated optimization problem aims to minimize the system activation time to satisfy the given traffic demands, under the constraint of multiple access interference and the limited available spectrum bands at each node. Then we develop a column generation (CG) approach to solve this problem. Our analytical model is validated by the simulation results, which provide a better performance compared with fixed bandwidth allocation.
Anthropometrics Related to the Performance of a Sample of Male Swimmers

The main purpose of the present investigation of 21 elite male swimmers was to assess whether the Ape Index (the ratio between the individual's arm span and height) and/or the second-to-fourth digit length ratio (2D:4D), i.e., the ratio between the length of the second and the fourth fingers of the right hand, are associated with the performance of high-level swimmers, when mood and / or executive function are covaried. The results showed no statistically significant correlation between the Ape Index and 2D:4D ratio, performance, executive function, or mood. In contrast, statistically significant correlations were found between 2D:4D ratio and performance, executive function, and mood. Regressions indicated that 2D:4D ratio and not Ape Index is related to the performances of a sample of male swimmers.
The TREC 2002 Arabic/English CLIR Track

Nine teams participated in the TREC-2002 cross-language information retrieval track, which focused on retrieving Arabic language documents based on 50 topics that were originally prepared in English. Arabic translations of the topic descriptions were also made available to facilitate monolingual Arabic runs. This was the second year in which a large Arabic document collection was available. Three new teams joined the evaluation, and the cross-language aspect of the evaluation received more attention this year than in TREC-2001. A set of standard linguistic resources was made available to facilitate cross-system comparisons, and their use as a contrastive condition was encouraged. Unique contributions to the relevance pools were more typical of previous TREC evaluations then the results of TREC-2001 had been for the same document collection, with no run uniquely contributing more than 6% of the known relevant documents.
Improvement of Acoustic Model in Text-independent Pronunciation Quality Assessment

In order to give an accurate assessment, the test speech should be recognized firstly in the text-independent pronunciation quality assessment system. Field test data has some flaws which degrade the recognition performance, such as noise, accent and spontaneous speaking style. In this paper, we investigate these factors by improving the acoustic model (AM) for the speech recognition system. Background noise is added to the training data to enhance the ability of anti-noise. Speaker-based Cepstral Mean and Variance Normalization (SCMVN) is adopted to alleviate the distortion of channel and the impact of inter-speaker pronunciation variability. Maximum a Posteriori (MAP) adaptation is applied twice, in order to tune acoustic model to match the pronunciation characteristic of the accent and the spontaneous style in spoken language. According to the experimental results, above measures increase the word correct rate relatively by 44.1% and the correlation coefficient between machine score and expert score relatively by 6.3%.

Tracking target using sensor networks: target detection and route activation under energy constraints

In this paper we consider tracking a target moving in a 2D plane using a network of sensors, each of which is capable of detecting presence of the target in its vicinity and communicating data to a central ldquotrackerrdquo. Information collated by the central tracker is presented in the from of a sub-set Sigmatk of sensors in whose vicinity the target is estimated to be present at time tk.Given that available energy in sensors is at a premium, we have proposed protocols for target detection and route activation that require sensors to conserve energy by switching between 'inactive' and 'active' modes of operations, while waking-up frequently in inactive mode to evaluate the need to become active. These protocols have been evaluated from the viewpoint of delay in target detection (or delay in route activation) and duty cycle, the fraction of the time for which a sensor is awake in inactive mode. Using simulation results we argue that this approach allows one to track a moving object with reasonable accuracy, provided the density of sensors is adequately large.
Python Bindings for the Open Source Electromagnetic Simulator Meep

This paper describes Meep, a popular free implementation of the finite-difference time-domain (FDTD) method for simulating electromagnetism. In particular, we focus on aspects of implementing a full-featured FDTD package that go beyond standard textbook descriptions of the algorithm, or ways in which Meep differs from typical FDTD implementations. These include pervasive interpolation and accurate modeling of subpixel features, advanced signal processing, support for nonlinear materials via Padé approximants, and flexible scripting capabilities.
Chinese police cadets’ attitudes toward police roles revisited

Purpose – The purpose of this paper is to examine the relationship between Chinese police cadets’ background, motivations and educational perceptions and their attitudes toward common police roles. Design/methodology/approach – Self-administered questionnaires were collected from 382 Chinese police cadets. Based upon predisposition and socialization theories, personal background, career motivation and attitudes toward education were examined as statistical explanations of cadets’ attitudes toward order maintenance, preventative patrol, law enforcement, and community building as elements of the police role. Findings – Cadets who recognized more value in their practical and academic education also significantly favored the transitional and contemporary police roles (preventative patrol, law enforcement, and community building), which are taught as part of their college curriculum. But educational perceptions had no effect on order maintenance, which is a more historical role, and not emphasized by the polic.
Randomness Conductors and Constant-Degree Expansion Beyond the Degree / 2 Barrier

The main concrete result of this paper is the first explicit construction of constant degree lossless expanders. In these graphs, the expansion factor is almost as large as possible: , where is the degree and is an arbitrarily small constant. Such graphs are essential components in networks that can implement fast distributed, routing algorithms e.g. [PU89, ALM96, BFU99]. They are useful in expander-based linear codes e.g. [SS96, Spi96, LMSS01]. Their highly unbalanced relatives are used in various storage schemes [UW87, BMRS00] and are the basis of hard tautologies for various proof systems [BW99, ABRW00, AR01]. The best previous explicit constructions gave expansion factor , which is too weak for the above applications. The bound was obtained via the eigenvalue method, and as shown in [Kah95], this method cannot give better bounds. The main abstract contribution of this paper is the introduction and initial study of randomness conductors, a notion which generalizes extractors, expanders, condensers and other similar objects. In all these functions, certain guarantee on the input “entropy” is converted to a guarantee on the output “entropy”. For historical reasons, specific objects used specific guarantees of different flavors (eg in expanders entropy means “support size”, and their property is satisfied whenever input entropy is small. In contrast, in extractors, entropy means “min-entropy” and their property is satisfied whenever input entropy is large). We show that the flexibility afforded by the conductor definition leads to interesting combinations of these objects, and to better constructions such as those above. The main technical tool in these constructions is a natural generalization to conductors, of the zig-zag products defined by [RVW00] for expanders and extractors. This product maintains certain conductivity properties of the conductors it combines, leading to new iterative constructions.
The Native POSIX Thread Library for Linux

Today’s demands for threads can hardly be satisfied by the LinuxThreads library implementing POSIX threads which is currently part of the standard runtime environment of a Linux system. It was not written with the kernel extensions we have now and in the near future available, it does not scale, and it does not take modern processor architectures into account. A completely new design is necessary and this paper will outline the design we came up with.
A Mathematical Model of T Lymphocyte Calcium Dynamics Derived from Single Transmembrane Protein Properties

Fate decision processes of T lymphocytes are crucial for health and disease. Whether a T lymphocyte is activated, divides, gets anergic, or initiates apoptosis depends on extracellular triggers and intracellular signaling. Free cytosolic calcium dynamics plays an important role in this context. The relative contributions of store-derived calcium entry and calcium entry from extracellular space to T lymphocyte activation are still a matter of debate. Here we develop a quantitative mathematical model of T lymphocyte calcium dynamics in order to establish a tool which allows to disentangle cause-effect relationships between ion fluxes and observed calcium time courses. The model is based on single transmembrane protein characteristics which have been determined in independent experiments. This reduces the number of unknown parameters in the model to a minimum and ensures the predictive power of the model. Simulation results are subsequently used for an analysis of whole cell calcium dynamics measured under various experimental conditions. The model accounts for a variety of these conditions, which supports the suitability of the modeling approach. The simulation results suggest a model in which calcium dynamics dominantly relies on the opening of channels in calcium stores while calcium entry through calcium-release activated channels (CRAC) is more associated with the maintenance of the T lymphocyte calcium levels and prevents the cell from calcium depletion. Our findings indicate that CRAC guarantees a long-term stable calcium level which is required for cell survival and sustained calcium enhancement.
Automatic Extraction of Acronyms from Text

A brief introduction to acronyms is given and motivation for extracting them in a digital library environment is discussed. A technique for extracting acronyms is given with an analysis of the results. The technique is found to have a low number of false negatives and a high number of false positives. Introduction Digital library research seeks to build tools to enable access of content, while making as few as possible assumptions about the content, since assumptions limit the range of applicability of the tools. Generally, the broader the assumptions the more widely applicable the tools. For example, keyword based indexing [5] is based on communications theory and applies to all natural human textual languages (allowances for differences in character sets and similar localisation issues not withstanding) . The algorithm described in this paper makes much stronger assumptions about the content. It assumes textual content that contains acronyms, an assumption which is known to hold for.
WO 6 Chemomentum — Grid environment to enable innovative research in computational chemistry

We have developed a fully flexible docking method that uses a reduced lattice representation of protein molecules, adapted for modeling peptide ligand — protein complexes. The CABS model (Carbon Alpha, Carbon Beta, Side Group) employed here was initially designed for single-chain protein folding, and performed well in many applications [Kolinski & Bujnicki, 2005]. Instead of full-atomic protein representation, the CABS model incorporates three pseudo-atoms per residue — Cα, Cβ and the center of the side group. Force field used by CABS was derived from statistical analysis of the non-redundant database of protein structures. In test applications the native state of the complex was reconstructed from separated molecules of the receptor and the peptide ligands. This was done for a set of protein complexes, for which three-dimensional structures are known, including the rat VDR vitamin D receptor bound to a short peptide mimicking its coactivator. Accuracy of obtained models [Kurcinski & Kolinski, 2007], calculated as cRMSD (coordinate Root-Mean-Square Deviation) between experimental and model structures, varied from 0. 7Å up to 4Å, which is competitive with experimental methods, such as crystallography or NMR. Construction of a fast and accurate flexible docking procedure is nowadays one of the most important tasks of bioinformatics and is crucial for rational drug design. A forthcoming modeling study should lead to a better understanding of mechanisms of macromolecular assembly and explain coactivator effects on receptor activity.

Information Retrieval in Network Administration

Network administration is a task that requires experience in relating symptoms of network problems with possible causes and corrective actions. We describe the design of a system and more specifically its information retrieval component, which aims to retrieve articles relevant to a given problem case from a collection of articles describing previously solved problems and their associated solutions. An article is described by a term vector. We present a methodology for defining the vocabulary and preliminary results for assessing the quality of expert-proposed modifications to the vocabulary. We obtain vocabulary-derived document classes from a self- organising map and assess vocabulary quality using the quality of classification into these classes.
Chronic intermittent hypoxia aggravates intrahepatic endothelial dysfunction in cirrhotic rats

Chronic intermittent hypoxia (CIH) occurs with obstructive sleep apnea syndrome (OSAS) and provokes systemic endothelial dysfunction, which is associated with oxidative stress and low nitric oxide (NO) bioavailability. Cirrhotic livers exhibit intrahepatic endothelial dysfunction, which is characterized by an impaired endothelium‐dependent response to vasodilators and hyperresponse to vasoconstrictors. We hypothesized that CIH may also contribute to intrahepatic endothelial dysfunction in cirrhosis. Normal and cirrhotic rats were exposed for 14 days to repetitive cycles of CIH mimicking OSAS in humans, or caged with room air (handled controls [HC]). Hepatic endothelial function was assessed in isolated and perfused rat livers by dose‐response curves to acetylcholine (ACh) and methoxamine (Mtx). In a group of cirrhotic rats, in vivo systemic and hepatic hemodynamic parameters were evaluated at baseline and after volume expansion. In addition, liver samples were obtained to assess endothelial nitric oxide synthase (eNOS), phosphorylated eNOS (p‐eNOS), NO bioavailability, and nitrotyrosinated proteins as a marker of oxidative stress. Cirrhotic rats exposed to CIH exhibited an attenuated vasodilatory response to ACh and hyperresponse to Mtx compared with HC rats. During volume expansion, similar portal pressure increases were observed in CIH and HC rats, although the mean arterial pressure increase was lower after CIH. These functional responses were associated with the presence of increased hepatic oxidative stress without changes in p‐eNOS after CIH exposure. In normal rats, no hemodynamic changes were found. Conclusion: CIH exacerbates intrahepatic endothelial dysfunction in cirrhotic rats, which is associated with increased oxidative stress that may reduce NO bioavailability. Clinical studies are needed to assess whether OSAS contributes to endothelial impairment in human patients with cirrhosis. (HEPATOLOGY 2013;57:1564–1574)
Link Evolution: Analysis and Algorithms

We anticipate that future web search techniques will exploit changes in web structure and content. As a first step in this direction, we examine the problem of integrating observed changes in link structure into static hyperlink-based ranking computations. We present a very efficient algorithm to incrementally compute good approximations to Google's PageRank [Brin and Page 98], as links evolve. Our experiments reveal that this algorithm is both fast and yields excellent approximations to PageRank, even in light of large changes to the link structure. Our algorithm derives intuition and partial justification from a rigorous sensitivity analysis of Markov chains. Consider a regular Markov chain with stationary probability π, and suppose the transition probability into a state j is increased. We prove that this can only cause • πj to increase–adding a link to a site can only cause the stationary probability of the target site to increase; • the rank of j to improve–if the states are ordered according to their stationary probabilities, then adding a link to a site can only cause the rank of the target site to improve. This analysis formalizes why the intuition that drives Google never fails.
Intrinsic Characterization of Dynamic Surfaces

This paper presents a novel approach to characterize deformable surface using intrinsic property dynamics. 3D dynamic surfaces representing humans in motion can be obtained using multiple view stereo reconstruction methods or depth cameras. Nowadays these technologies have become capable to capture surface variations in real-time, and give details such as clothing wrinkles and deformations. Assuming repetitive patterns in the deformations, we propose to model complex surface variations using sets of linear dynamical systems (LDS) where observations across time are given by surface intrinsic properties such as local curvatures. We introduce an approach based on bags of dynamical systems, where each surface feature to be represented in the codebook is modeled by a set of LDS equipped with timing structure. Experiments are performed on datasets of real-world dynamical surfaces and show compelling results for description, classification and segmentation.
