Analytical Review of the News Data Classification Methods with Multivariate Classification Attributes

The new classification has been emerged as the important sub-branch of the data mining. A lot of work has been already done on the news classification with variety of classifiers and feature descriptors. A number of news classification projects are working on the real-time systems in existence today. The news classification is the important part of the online news portals. The online news portals are rising every year, and adding more users to the news portals. The news classification is the branch of text classification or text mining. The researchers have already done a lot of work on the text classification models with different approaches. The news works has to be classified in the form of various categories such as sports, political, technology, business, science, health, regional and many other similar categories. The researchers have already worked with many supervised and unsupervised methods for the purpose of news classification. The supervised models have been found more efficient for the purpose of news classification. The major goal of the news classification research is to improve the accuracy while decreasing the elapsed time. Our news classification models purposes the use of k-means and lexicon analysis of the news data with nearest neighbor algorithm for the news classification. The k-means algorithm is the clustering algorithm and used primarily to produce the text data clusters with the important information. Then the lexicon analysis would be performed over the given text data and then final classification of the news is done using k-nearest neighbor. The results would be obtained in the form of the parameters of accuracy, elapsed time, etc.
Procalcitonin as a diagnostic and prognostic marker for sepsis caused by intestinal infection: a case report.

BACKGROUND In recent years, procalcitonin has emerged as a promising marker for bacterial infection, with the high sensitivity and specificity. CASE PRESENTATION This report presents a 76-year-old woman with fever, vomiting and diarrhea. The clinical and laboratory examination revealed that the patient had a suspected serious intestinal infection and sepsis. The extremely high level of procalcitonin and positive blood culture result confirmed our diagnosis. CONCLUSIONS Early identification of severe sepsis sometimes is very difficult. Procalcitonin is a useful tool in the early diagnosis of sepsis, differentiating from other inflammatory syndrome. The high PCT level (10 ng/ml) in this case could suggest serious bacterial infection and sepsis, and also predicts mortality and worse outcome.

Adaptation of guinea‐pig vagal airway afferent neurones to mechanical stimulation

1 Intracellular and extracellular electrophysiological recording techniques were employed to examine the mechanisms involved in adaptation of guinea‐pig airway sensory neurones to suprathreshold mechanical stimulation in vitro. Extracellular recordings performed using an in vitro airway preparation revealed two unambiguously distinct subsets of mechanically sensitive nerve endings in the trachea/bronchus. In one group of fibres, the mechanical stimulus caused a brief burst of action potentials, after which the nerve rapidly adapted. In the other group of fibres, repetitive action potentials were evoked as long as the stimulus was maintained above threshold. 2 The adaptation response strictly correlated with ganglionic origin of the soma. Those fibres derived from the nodose ganglion adapted rapidly, whereas those derived from the jugular ganglion were slowly or non‐adapting. 3 Intracellular recordings from airway‐identified neurones in isolated intact ganglia revealed that the majority of neurones within either the nodose or jugular ganglion adapted rapidly to prolonged suprathreshold depolarizing current injections. 4 The electrophysiological adaptation of nodose ganglion‐derived neurones following prolonged suprathreshold current steps was greatly reduced by 4‐aminopyridine. However, 4‐aminopyridine did not affect the adaptation of rapidly adapting nodose ganglion‐derived nerve endings in response to mechanical stimuli. 5 The data suggest that ganglionic origin dictates adaptive characteristics of guinea‐pig tracheal and mainstem bronchial afferent neurones in response to mechanical stimulation. Also, the rapid adaptation of nodose nerve endings in the trachea observed during a mechanical stimulus does not appear to be related to the adaptation observed at the soma during prolonged suprathreshold depolarizing current injections.
Mechanism of Differential Cardiovascular Response to Propofol in Dahl Salt-Sensitive, Brown Norway, and Chromosome 13-Substituted Consomic Rat Strains: Role of Large Conductance Ca2+ and Voltage-Activated Potassium Channels

Cardiovascular sensitivity to general anesthetics is highly variable among individuals in both human and animal models, but little is known about the genetic determinants of drug response to anesthetics. Recently, we reported that propofol (2,6-diisopropylphenol) causes circulatory instability in Dahl salt-sensitive SS/JRHsdMcwi (SS) rats but not in Brown Norway BN/NHsdMcwi (BN) rats and that these effects are related to genes on chromosome 13. Based on the hypothesis that propofol does target mesenteric circulation, we investigated propofol modulation of mesenteric arterial smooth muscle cells (MASMC) in SS and BN rats. The role of chromosome 13 was tested using SS-13BN/Mcwi and BN-13SS/Mcwi consomic strains with chromosome 13 substitution. Propofol (5 μM) produced a greater in situ hyperpolarization of MASMC membrane potential in SS than BN rats, and this effect was abrogated by iberiotoxin, a voltage-activated potassium (BK) channel blocker. In inside-out patches, the BK channel number, Po, and apparent Ca2+ sensitivity, and propofol sensitivity all were significantly greater in MASMC of SS rats. The density of whole-cell BK current was increased by propofol more in SS than BN myocytes. Immunolabeling confirmed higher expression of BK α subunit in MASMC of SS rats. Furthermore, the hyperpolarization produced by propofol, the BK channel properties, and propofol sensitivity were modified in MASMC of SS-13BN/Mcwi and BN-13SS/Mcwi strains toward the values observed in the background SS and BN strains. We conclude that differential function and expression of BK channels, resulting from genetic variation within chromosome 13, contribute to the enhanced propofol sensitivity in SS and BN-13SS/Mcwi versus BN and SS-13BN/Mcwi strains.
Hemodialysis-induced regional left ventricular systolic dysfunction: prevalence, patient and dialysis treatment-related factors, and prognostic significance.

BACKGROUND AND OBJECTIVES The hemodialysis procedure may acutely induce regional left ventricular systolic dysfunction. This study evaluated the prevalence, time course, and associated patient- and dialysis-related factors of this entity and its association with outcome. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS Hemodialysis patients (105) on a three times per week dialysis schedule were studied between March of 2009 and March of 2010. Echocardiography was performed before dialysis, at 60 and 180 minutes intradialysis, and at 30 minutes postdialysis. Hemodialysis-induced regional left ventricular systolic dysfunction was defined as an increase in wall motion score in more than or equal to two segments. RESULTS Hemodialysis-induced regional left ventricular systolic dysfunction occurred in 29 (27%) patients; 17 patients developed regional left ventricular systolic dysfunction 60 minutes after onset of dialysis. Patients with hemodialysis-induced left ventricular systolic dysfunction were more often male, had higher left ventricular mass index, and had worse predialysis left ventricular systolic function (left ventricular ejection fraction). The course of blood volume, BP, heart rate, electrolytes, and acid-base parameters during dialysis did not differ significantly between the two groups. Patients with hemodialysis-induced regional left ventricular systolic dysfunction had a significantly higher mortality after correction for age, sex, dialysis vintage, diabetes, cardiovascular history, ultrafiltration volume, left ventricular mass index, and predialysis wall motion score index. CONCLUSIONS Hemodialysis induces regional wall motion abnormalities in a significant proportion of patients, and these changes are independently associated with increased mortality. Hemodialysis-induced regional left ventricular systolic dysfunction occurs early during hemodialysis and is not related to changes in blood volume, electrolytes, and acid-base parameters.
Disappearing act: Persistence and attrition of uniform resource locators (URLs) in an open access medical journal

Purpose – The aim of this paper is to assess and catalogue the magnitude of URL attrition in a high‐impact, open access (OA) general medical journal. Design/methodology/approach – All Public Library of Science Medicine (PLoS Medicine) articles for 2005‐2007 were evaluated and the following items were assessed: number of entries per issue; type of article; number of references per entry; number of references that contained URLs; and the access date listed for each URL citation. URLs were then evaluated for accessibility status (i.e. active or defunct). Findings – In total, 1,133 articles were published from 2005‐2007 in PLoS Medicine. The 1,133 articles contained 28,177 references, with 2,503 (8.9 per cent) identified as URLs. Non‐research articles accounted for a substantially higher percentage of URL references (17.4 per cent) compared to research articles (4.2 per cent). Almost 17 per cent of the URL references were defunct and the rate of URL attrition increased as time elapsed. Research limitations/implications – Information management policy makers need to re‐examine the importance of preserving the internet materials long term. Both publisher and author should expand efforts to preserve internet materials. Common guidelines should be developed (e.g. by the International Committee of Medical Journal Editors) and implemented by all publishers to address URL use as references. Originality/value – This article will be of interest to those in the field.
Heart rate variability biofeedback: Theoretical basis, delivery, and its potential for the treatment of substance use disorders

Abstract Heart rate variability biofeedback (HRV BFB) is a biobehavioural clinical intervention that is gaining growing empirical support for the treatment of a number of psychological disorders, several of which are highly comorbid with substance use disorders (SUDs). The present article reviews the autonomic nervous system bases of two key processes implicated in the formation and maintenance of addictive pathology—affect dysregulation and craving—and asks if HRV BFB may be an effective intervention to ameliorate autonomic nervous system dysregulation in these processes, and as such, prove to be an effective intervention for SUDs. A detailed description of HRV BFB and its delivery is provided. Preliminary evidence suggests HRV BFB may be an effective addendum to current first-line SUD treatments, though no firm conclusions can be drawn at this time; more research is needed.
On the implementation of path switching over SDN-enabled network: A prototype

Since Software-Defined Networking (SDN) technologies have been commonly used in networking components for designing Future Internet, the fault tolerance design becomes a fundamental requirement in network deployment. This paper presents a prototype of path switching method based on OpenFlow protocol. In contrast of the traditional network architecture, this implementation provides an adaptive path switching method when link failure is detected, which reducing the time of interruption.

Incubation of alligator snapping turtle ( Macrochelys temminckii ) eggs in natural and agricultural soils

Physicochemical properties of incubation substrates may affect embryonic growth, development, and sexual differentiation in oviparous species with temperature-dependent sex determination. Thus, the physicochemical modification of incubation substrates associated with anthropogenic activities may pose a risk to normal embryonic and hatchling development in the alligator snapping turtle (Macrochelys temminckii), an oviparous species with temperature-dependent sex determination. The present study evaluated the development of alligator snapping turtle embryos and hatchlings incubated in vermiculite, and in Tunica Soils Series from a natural nesting area and from a cotton farm. Differences between agricultural and natural soils included particle size composition, concentrations of phosphorus, nitrates (NO3), magnesium, manganese, potassium, calcium, sodium, and copper concentrations, salinity, and cation exchange capacity (CEC). Soil pH, and iron, boron and sulfate (SO4) concentrations were similar. Agricultural soils received applications of herbicides (glyphosate, fluometuron, pyrithiobac sodium, 2,4-D, trifluralin) and insecticides (methyl parathion, dicrotophos), and natural soils did not. No significant differences were detected in incubation period, clutch success, hatchling mass, sex ratio, or frequency of abnormalities in offspring from the different incubation substrates. Increases over a four-month period in mass and tail length of hatchlings incubated in natural soils were, however, significantly greater than in hatchlings incubated in other substrates. We therefore suggest that future studies should examine how physicochemical factors of incubation substrate affect hatchling growth.
Vertigo in MS: Utility of positional and particle repositioning maneuvers

Article abstract A 4-year experience with new-onset vertigo in a university-based MS population was retrospectively reviewed. Of 1,153 patients with MS, 25 could be clinically evaluated during the vertiginous episode. Of these, 13 (52%) were diagnosed with benign paroxysmal positioning vertigo and eight (32%) had acute MS exacerbations with corresponding lesions within the brainstem. All patients diagnosed with benign paroxysmal positioning vertigo were treated successfully with particle repositioning maneuvers. –1568
Field weakening implementation in AC induction machine predictive control

AC induction motors become very popular for motion control applications due to their simple and reliable construction. Control of drives based on AC induction motors is a quite complex task. In most high-performance applications classical vector control is currently used. While this control method is usually reliable it has some limitations especially in controllers tuning and constraints handling. In the current paper we present an AC induction machine control method based on model predictive control including field weakening strategy. The proposed control algorithm has been proved and successfully verified in simulation.

Oral anticoagulant use in addition to antiplatelet therapy for secondary prevention in acute coronary syndrome: current perspectives

Patients with acute coronary syndrome (ACS) are typically managed with long-term dual antiplatelet therapy of acetylsalicylic acid plus a P2Y12 platelet receptor antagonist; however, although effective, the risk of another vascular event within 12 months remains at approximately 10%. Considerable efforts have been made to find improved therapeutic approaches to secondary prevention in ACS. The ATLAS ACS 2-TIMI 51 trial demonstrated that rivaroxaban (2.5 mg twice daily) significantly reduced recurrent vascular events, increased the risk of major bleeding but not the risk of fatal bleeding, and resulted in reduced rates of death from cardiovascular causes. These results formed the basis for approval in Europe of rivaroxaban (2.5 mg twice daily) in conjunction with standard antiplatelet therapy for the secondary prevention of ACS.
Organic Field‐Effect Transistors

Organic field-effect transistors (OFETs) were first described in 1987. Their characteristics have undergone spectacular improvements during the last two or three years. At the same time, several models have been developed to rationalize their operating mode. In this review, we examine the performance of OFETs as revealed by recently published data, mainly in terms of field-effect mobility and on–off current ratio. We compare the various compounds that have been used as the active component, and describe the most prominent fabrication techniques. Finally, we analyze the charge transport mechanisms in organic solids, and the resulting models of OFETs.
W # hi ngaro (the lost portion): Strengthening relationships between people and wetlands in north Taranaki, New Zealand

During the last twenty years M # ori have endeavoured to re-establish control over their material culture and spiritual relationship to the landscape working through new associations with local bodies, museums and researchers. One of their concerns is with cultural wetlands. Wetlands contain M # ori , archaeological and ecological values. Despite this, current legislation offers little or no protection for these fragile ecosystems or for the spiritual concerns of M # ori . The previously extensive wetlands of Taranaki have been partly drained to produce farmland, and many waterlogged wooden artefacts have been recovered. On-going drainage continues to place these sites at risk. This paper outlines our efforts to strengthen the relationship between Ng # ti Mutunga of north Taranaki and their wetlands through a research programme in which Ng # ti Mutunga play an active role. Our joint venture has required effort and understanding from both parties, and the research programme's aims and procedures have been altered to accommodate M # ori concerns.
Analysis and Detection of Malicious Behaviors in Repackaged Android Applications

Context Over the past decades malware authorship grew to become a profession. Nowadays, there exists a plethora of malware instances that span various targets, structures, motivations, and objectives [1]. Despite the different objectives they pursue, the majority of malware authors strive to prolong the period of time their instances remain operational within the infected system. In this context, malware instances are designed to evade the detection mechanisms employed by antiviral software. It is, therefore, not uncommon for modern malware to obfuscate its internal structure, alter its runtime behavior, trigger its malicious intents upon the realization of preset conditions or mimic the behavior of a benign application to evade detection [4].
Sexual Selection on Human Faces and Voices

Humans are highly sexually dimorphic primates, and some of the most conspicuous human sex differences occur in the face and voice. Consequently, this article utilizes research findings on human faces and voices to illustrate how human sex differences may have arisen by sexual selection (i.e., the type of natural selection favoring traits that increase mating opportunities). Evidence suggesting that sexual selection shaped women's faces and voices is reviewed. However, sexual selection likely operated more strongly on men over human evolution. Thus, this research focuses on two types of sexual selection operating on men: female mate choice, which favors traits that attract females, and male contests, which favor traits for excluding competitors from mates by force or threat of force. This article demonstrates how masculine faces and voices advertize critical information about men's mate value and threat potential, and reviews evidence that women's preferences and men's deference to masculine faces and voices reflect this information content. Data suggesting that facial and vocal masculinity influences men's mating opportunities and reproduction are discussed, and the article concludes by highlighting directions for future research.
Post-Transcriptional Gene Regulation by MicroRNA and RNA-Binding Protein

Recent advanced studies have demonstrated that post-transcriptional gene regulation is involved in many aspects of biological processes and in the pathogenesis of various types of disorders, such as neurodegenerative diseases, autoimmune diseases, and cancer. In addition to transcriptional regulation, spatially and temporally regulated gene expression is achieved by the post-transcriptional control of transcribed RNAs, including through splicing, export, stability, localization, and translation. These processes are regulated by the formation of ribonucleoprotein complexes with RNA-binding proteins and small non-coding RNAs. Here, we will describe the findings obtained from studies on mice deficient for individual RNA-binding proteins and microRNAs involved in maintaining homeostasis or causing disease.
Transformers Surveillance Following Corrosive Sulfur Remedial Procedures

Over the last decade, dibenzyl-disulphide was found to be present in a large number of mineral insulating oils. This sulfur compound tends to react with the copper of the windings, forming harmful byproducts, such as Cu2 S. Different techniques to overcome the problem, including metal deactivation, oil change, and chemical treatment, have been applied. The long-term effectiveness of these techniques is examined and compared.
