Empirical Study of Individual Feature Evaluators and Cutting Criteria for Feature Selection in Classification

The use of feature selection can improve accuracy, efficiency, applicability and understandability of a learning process and its resulting model. For this reason, many methods of automatic feature selection have been developed. By using a modularization of feature selection process, this paper evaluates a wide spectrum of these methods. The methods considered are created by combination of different selection criteria and individual feature evaluation modules. These methods are commonly used because of their low running time. After carrying out a thorough empirical study the most interesting methods are identified and some recommendations about which feature selection method should be used under different conditions are provided.
Methodologies and Tools of the Modern (e-) Learning Using Reengineering Techniques for Distance Study Course Improvement

The paper analyses the reengineering concept as it comes from software engineering and management fields. We combine two viewpoints and apply them to solve a problem of reengineering of a distance study system, in general, and the unit of learning, in particular. We propose a framework for reengineering of unit of learning, based on general model of software reengineering, and present a case study, in which we describe, how one topic of distance study course was reengineered, considering triple consistency principle and requirements for computer science. The proposed framework contributes to increasing quality, effectiveness and systematization of delivering distance studies.
[Biological effect of electrical plum-blossom needle for treatment of juvenile myopia].

OBJECTIVE To observe therapeutic effect of electrical plum-blossom needle for treatment of juvenile myopia and biological effect on ocular tissue and structures. METHODS One hundred and sixty cases with mild myopia (diopter < 3.00D) were randomly divided into two groups, a treatment group and a control group. The treatment group were treated with electrical plum-blossom needle therapy, tapping Jingming (BL 1), Chengqi (ST 1), Taiyang (EX-HN 5) and Neiguan (PC 6), and the control group with Tropicamide eye drops. The changes of vision, diopter, corneal refractive power, ocular-axial length, lens and ciliaris thickness were observed before and after treatment. RESULTS The total effective rate was 80.0% in the treatment group and 58.1% in the control group, with a very significant difference between the two groups (P < 0.01); the two therapies could decrease the thickness of lens and ciliaris, and eliminate spasm of ciliary muscle, however the electrical plum-blossom needle therapy had more obvious action (P < 0.05); the two therapies had no effect on the corneal refractive power and ocular-axial length. CONCLUSION The electrical plum-blossom needle therapy is an effective method for increasing vision, correcting ametropia and delaying development of myopia.
A novel technique to specifically analyze the secretome of cells and tissues

The secretome of cells and tissues may reflect a broad variety of pathological conditions and thus represents a rich source of biomarkers. The identity of secreted proteins, usually isolated from cell supernatants or body fluids, is hardly accessible by direct proteome analysis, because these proteins are often masked by high amounts of proteins actually not secreted by the investigated cells. Here, we present a novel method for the specific detection of proteins secreted by human tissue specimen as well as cultured cells and chose liver as a model. The method is based on the metabolic labelling of proteins synthesized during a limited incubation period. Then, the cell supernatant is filtered, precipitated, and subjected to two‐dimensional gel electrophoresis. Whereas fluorography detected a large number of proteins derived from residual plasma and dead cells, the autoradiographs selectively displayed genuinely secreted proteins. We demonstrate the feasibility of this approach by means of the secretomes of the hepatocellular carcinoma‐derived cell line HepG2 and human liver slices. The selective identification of cell‐ and tissue‐specific protein secretion profiles may help to identify novel sets of biomarkers for wide clinical applications.
Topological Centrality and Its Applications

Recent development of network structure analysis shows that it plays an important role in characterizing complex system of many branches of sciences. Different from previous network centrality measures, this paper proposes the notion of topological centrality (TC) reflecting the topological positions of nodes and edges in general networks, and proposes an approach to calculating the topological centrality. The proposed topological centrality is then used to discover communities and build the backbone network. Experiments and applications on research network show the significance of the proposed approach.
Peach cell number and size is affected by crop load and cultivar

Peach fruit development is impacted by crop load, cultivar genetics, and temperature during the Phase I growth stage after fruit set. Four peach cultivars, 'Carored', 'Summerprince', 'Scarletprince' and 'Redhaven', ripening from mid-May to early July were selected for fruitlet sampling every 5 days from week 2 to week 5 post-bloom. Fruitlets were collected mid-shoot, 1.5 m above ground, from the exterior of all four sides of the tree. Fruitlets were fixed with FAA (ethanol-formaldehyde-acetic acid) before mounting for sectioning. Trees of each cultivar were either thinned one week or four weeks after petal fall. There were four single-tree replicates for each cultivar and treatment. Mesocarp cell number and size were recorded from transverse sections using Infinity Analyze software. Differences in cell number due to crop load were observed within days after early thinning. Early thinned trees had 8 to 19% more cells than later thinned trees 3 weeks after the first thinning date. At week 4 post-bloom, the two later ripening cultivars, 'Redhaven' and 'Scarletprince', had more cells than the two early ripening cultivars. Differences in cell size occurred with 5 days of thinning for the earliest cultivar, 'Carored'. The other 3 cultivars did not see differences in cell size between treatments until 2 weeks after the earliest thinning treatment. Three weeks after the early thinning, fruit from early thinned trees had cells 5% ('Summerprince') to 43% ('Carored') larger than the later thinned trees. At week 5, early cultivars had larger cell size than the later ripening cultivars. Fruit from the early thinned trees ripened earlier and were larger at harvest.
The Shifting Demographic Landscape of Pandemic Influenza

Background As Pandemic (H1N1) 2009 influenza spreads around the globe, it strikes school-age children more often than adults. Although there is some evidence of pre-existing immunity among older adults, this alone may not explain the significant gap in age-specific infection rates. Methods and Findings Based on a retrospective analysis of pandemic strains of influenza from the last century, we show that school-age children typically experience the highest attack rates in primarily naive populations, with the burden shifting to adults during the subsequent season. Using a parsimonious network-based mathematical model which incorporates the changing distribution of contacts in the susceptible population, we demonstrate that new pandemic strains of influenza are expected to shift the epidemiological landscape in exactly this way. Conclusions Our analysis provides a simple demographic explanation for the age bias observed for H1N1/09 attack rates, and suggests that this bias may shift in coming months. These results have significant implications for the allocation of public health resources for H1N1/09 and future influenza pandemics.
Development, Implementation and Operation of Integrated Sanitation Systems Based on Material-Flows – Integrated Sanitation in the City of Darkhan, Mongolia - A Practicable Example

The world society faces a huge challenge to implement the human right of “access to sanitation”. More and more it is accepted that the conventional approach towards providing sanitation services is not suitable to solve this problem. This dissertation examines the possibility to enhance “access to sanitation” for people who are living in areas with underdeveloped water and wastewater infrastructure systems. The idea hereby is to follow an integrated approach for sanitation, which allows for a mutual completion of existing infrastructure with resource-based sanitation systems. The notion “integrated sanitation system (iSaS)” is defined in this work and guiding principles for iSaS are formulated. Further on the implementation of iSaS is assessed at the example of a case study in the city of Darkhan in Mongolia. More than half of Mongolia’s population live in settlements where yurts (tents of Nomadic people) are predominant. In these settlements (or “ger areas”) sanitation systems are not existent and the hygienic situation is precarious. An iSaS has been developed for the ger areas in Darkhan and tested over more than two years. Further on a software-based model has been developed with the goal to describe and assess different variations of the iSaS. The results of the assessment of material-flows, monetary-flows and communication-flows within the iSaS are presented in this dissertation. The iSaS model is adaptable and transferable to the socio-economic conditions in other regions and climate zones.
ON THE EXPONENT OF R-REGULAR PRIMITIVE MATRICES ∗

Let Pnr be the set of n-by- nr -regular primitive (0,1)-matrices. In this paper, an explicit formula is found in terms of n and r for the minimum exponent achieved by matrices in Pnr. Moreover, matrices achieving that exponent are given in this paper. Gregory and Shen conjectured that bnr = n 2 + 1 is an upper bound for the exponent of matrices in Pnr . M atrices achieving the exponent bnr are presented for the case when n is not a multiple of r. In particular, it is shown that b2r+1,r is the maximum exponent attained by matrices in P2r+1,r . W henn is a multiple of r ,i t is conjectured that the maximum exponent achieved by matrices in Pnr is strictly smaller than bnr. Matrices attaining the conjectured maximum exponent in that set are presented. It is shown that the conjecture is true whenn =2 r.
A concurrent design methodology of a production system for virtual commissioning

In this article, a concurrent design procedure of a production system is presented, which supports the virtual commissioning between a real controller and a virtual plant consisting of virtual devices. To achieve the concurrency, we split a virtual device model into two parts, a physical device model (a geometric model with kinematics for the motion programming of tasks) and a logical device model (a behavioral model to interact with a real controller). The whole design procedure consists of four major steps: (1) process design, (2) physical device modeling, (3) logical device modeling, and (4) system control modeling. First, the process design step identifies effective manufacturing processes and produces the sequence of operations. Once the sequence of operations is obtained at Step 1, then the other three steps can be performed concurrently without interfering each other. All the three concurrent steps start from the sequence of operations, and a detailed procedure for each of the step has been developed. The concurrent attribute of the proposed design procedure significantly contributes to the saving of the delays in time to market. The proposed design procedure has been implemented and tested for various examples.
Development of an 85-kW Bidirectional Quasi-Z-Source Inverter With DC-Link Feed-Forward Compensation for Electric Vehicle Applications

This paper presents a detailed operation analysis, controller design, and realization of a high-power, bidirectional quasi-Z-source inverter (BQ-ZSI) for electric vehicle applications. The circuit analysis shows that with a bidirectional switch in the quasi-Z-source network, the performance of the inverter under small inductance and low power factor can be improved. Based on the circuit analysis, a small signal model of the BQ-ZSI is derived, which indicates that the circuit is prone to oscillate when there is disturbance on the dc input voltage. Therefore, a dedicated voltage controller with feed-forward compensation is designed to reject the disturbance and stabilize the dc-link voltage during a non-shoot-through state. An 85-kW prototype has been built. Both simulation and experimental results are presented to prove the functionality of the circuit and the effectiveness of the proposed control strategy.
NetReview: Detecting When Interdomain Routing Goes Wrong

Despite many attempts to fix it, the Internet's interdomain routing system remains vulnerable to configuration errors, buggy software, flaky equipment, protocol oscillation, and intentional attacks. Unlike most existing solutions that prevent specific routing problems, our approach is to detect problems automatically and to identify the offending party. Fault detection is effective for a larger class of faults than fault prevention and is easier to deploy incrementally. To show that fault detection is useful and practical, we present NetReview, a fault detection system for the Border Gateway Protocol (BGP). NetReview records BGP routing messages in a tamper-evident log, and it enables ISPs to check each other's logs against a high-level description of the expected behavior, such as a peering agreement or a set of best practices. At the same time, NetReview respects the ISPs' privacy and allows them to protect sensitive information. We have implemented and evaluated a prototype of NetReview; our results show that NetReview catches common Internet routing problems, and that its resource requirements are modest.
The Potential Role of Physical Activity in the Prevention of Non‐Insulin‐Dependent Diabetes Mellitus: The Epidemiological Evidence

Examining the epidemiological literature, a relationship between physical activity and the development of NIDDM seems not only plausible but likely. What is needed is a randomized clinical trial to confirm the metabolic and epidemiological research findings to date. To maximize success of a diabetes prevention trial, both diet and physical activity should be part of the intervention. The relative importance of diet or physical activity as components of the intervention will vary, depending upon the participant. However, it is critical that compliance with the physical activity and diet intervention be maintained, for this question to be answered. If the intervention is successful, the participants will have made lifestyle changes that have the potential of lasting beyond the closure of the clinical trial.
HYDROLOGIC AND WATER QUALITY EFFECTS OF THINNING LOBLOLLY PINE

Forest operations such as harvesting, thinning, and site preparation can affect the hydrologic behavior of watersheds on poorly drained soils. The influence of these operations conducted on organic soil sites can be more pronounced than on mineral soil sites due to the differences in bulk density and soil moisture relationships that exist between mineral and organic soils. This article reports the results of a study to evaluate the effect of thinning on the hydrology and water quality of an artificially drained pine plantation watershed on organic soils in eastern North Carolina. Outflow, water table depth, and water quality were monitored over a 3-year study period from paired 40 ha and 16 ha 15-year-old loblolly pine (Pinus taeda L.) plantations located in Washington County near Plymouth, North Carolina. Thinning increased daily outflow and peak flow rates based on a paired-watershed study design. Mean daily outflow doubled and peak flow rates increased 40% on the thinned watershed in relation to the control. Treatment effects were also observed on nutrient loads following the thinning operation. Phosphorous, TKN, and TSS loads increased following thinning, while nitrate-nitrogen loads decreased following thinning. These differences in hydrologic behavior are primarily attributed to the reduction in evapotranspiration that resulted from thinning.
Number 641 Computer Laboratory UCAM-CL-TR-641 ISSN 1476-2986 Cryptographic processors – a survey

Tamper-resistant cryptographic processors are becoming the standard way to enforce data-usage policies. Their history began with military cipher machines, and hardware security modules that encrypt the PINs used by bank customers to authenticate themselves to ATMs. In both cases, the designers wanted to prevent abuse of data and key material should a device fall into the wrong hands. From these specialist beginnings, cryptoprocessors spread into devices such as prepayment electricity meters, and the vending machines that sell credit for them. In the 90s, tamper-resistant smartcards became integral to GSM mobile phone identification and to key management in pay-TV set-top boxes, while secure microcontrollers were used in remote key entry devices for cars. In the last five years, dedicated crypto chips have been embedded in devices from games console accessories to printer ink cartridges, to control product and accessory aftermarkets. The ‘Trusted Computing’ initiative will soon embed cryptoprocessors in PCs so that they can identify each other remotely. This paper surveys the range of applications of tamperresistant hardware, and the array of attack and defence mechanisms which have evolved in the tamper-resistance
Construction of K-Dimensional Delaunay Triangulations Using Local Transformations

In [SIAM J. Sci. Statist. Comput. ,10 (1989), pp. 718–741] and [Comput. Aided Geom. Des. , 8 (1991), pp. 123–142] the author presented algorithms that use local transformations to construct a Delaunay triangulation of a set of n three-dimensional points. This paper proves that local transformations can be used to construct a Delaunay triangulation of a set of nk-dimensional points for any $k \geq 2$, and presents algorithms using this approach. The empirical time complexities of these algorithms are discussed for sets of random points from the uniform distribution as well as worst-case time complexities. These time complexities are about the same or better than those of other algorithms for constructing k-dimensional Delaunay triangulations (when $k \geq 3$).

A pooled analysis of alcohol intake and colorectal cancer.

OBJECT In order to provide an updated quantification of the association between alcohol intake and colorectal cancer, we conducted a meta-analysis of published observational studies. METHOD Two cohort and 22 case-control studies presenting results for at least three categories of alcohol intake were identified from a PubMed search of articles published before July 2014. Data were extracted independently by two reviewers. Random effects meta-analyses, subgroup analyses, and meta regression were performed for modeling the dose-response relation. RESULT The pooled relative risk (RR) for any alcohol intake compared with non/occasional drinking was 1.13 [95% confidence interval (CI), 1.09-1.17]. The RRs were 1.07 (95% CI, 1.02-1.13), 1.23 (95% CI, 1.15-1.32) and 1.37 (95% CI, 1.26-1.49) for light (≤12.5 g/day), moderate (12.6 to 49.9 g/day) and heavy drinking (≥50 g/day), respectively. The risks were consistent in the subgroup analyses of sex and tumor site. CONCLUSION This meta-analysis provides strong evidence for an association between alcohol intake and colorectal cancer risk.

2 Object Oriented Semantics : An Overview 2 . 1 Formalising Semantics

Object oriented models and methods encompass a set of techniques which have been, and will continue to be, applied in the successful production of complex software systems. The methods are based on the simple concepts of abstraction, encapsulation, classification and polymorphism. The formal verification of logical properties of such models is difficult to integrate into the traditional operational view. Furthermore, most, if not all, of the object oriented formalisms are based on the specification of safety properties and, as such, they do not provide an adequate means of expressing liveness conditions. We examine a mixed semantic framework in which a state-based object oriented semantics is extended with the concepts of always and eventually. These semantics have been integrated to provide a set of re-usable fair object templates whose graphical representation can be formalised by the client for use during synthesis and analysis of their requirements. Proof of invariant and eventuality properties is done by translation to PVS and TLA, respectively. The utility of such an approach is illustrated through a simple telephone feature case study.
