Dynamics of online chat

Millions of people use online synchronous chat networks on a daily basis for work, play and education. Despite their widespread use, little is known about their user dynamics. For example, one does not know how many users are typically co-present and actively engaged in public interaction in the individual chat rooms of any of the numerous public Internet Relay Chat (IRC) networks found on the Internet; or what are the factors that constrain the boundaries of user activity inside those chat rooms. Failure to collect and present such data means there is a lack of a good understanding of the range of user interaction dynamics that large-scale chat technologies support. This dissertation addresses this gap in the research literature through a year-long field study of the user-dynamics of Austnet, a medium-sized IRC network (103 million messages sent to 7,180 publicly active chat-channels by 489,562 unique nicknames over a one-year period). Key results include: (1) the first rich quantitative description of a medium-sized chat network; (2) empirical evidence for user information-processing constraints to patterns of chat-channel engagement (maximum 40 posters and 600 public messages per chat-channel per 20-minute interval); (3) a short-term channel engagement model which highlights the extent to which immediate channel activity can be reliably predicted, and identifies the best predictor variables; (4) a model for the identification of factors that can be used to distinguish highly predictable channels from unpredictable channels; and (5) the first empirical study of how the Critical Mass theory can help in predicting the channels' long-term chances of survival by looking at their initial starting conditions. Collectively, the results highlight how the knowledge of chat network dynamics can be used in making accurate predictions about the chat-channels' levels of short-term activity, and long-term survivability. This is important because it can lead to improved designs of future synchronous chat technologies. Such designs would benefit both the users of the systems, by providing them real-time recommendations about where to find successful group discourse, and the managers of the systems, by providing them vital information about the health of their communities.
Pain in cancer patients with advanced stage disease

Oncologic pain, in some situations, happens quickly. The transition for a process of advanced disease may occur during the state of diagnosis, state of treatment, because of the ineffectiveness of the treatment, or afterwards in a case of relapse. The pain is defined by International Association for the Study of Pain (IASP), as “an unpleasant sensory and emotional experience associated with actual or potential tissue damage, or described in terms of such damage” [1]. The pain is a vital sign whose manifestation leads to the search of health care. In this way is of great importance as warming signal of physiological, psychological, social or spiritual change, in a latent state. No pain control may be the cause of pathophysiologic dysfunctions which lead to physical, psychic, social and spiritual changes that affect patient and caregiver.
Access to Immunological Markers for the Management of Rheumatoid Arthritis in Togo with Regard to 2010 ACR/EULAR Classification

Rheumatoid arthritis (RA) is a chronic inflammatory rheumatism with an autoimmune component and destruction of synovial joints, leading to severe disability and premature mortality [1]. It is the most common chronic inflammatory rheumatism in the world with a prevalence of 0.5 to 1% [2]. For a long time, it was assumed that RA was rare in black Africa, but more recently, studies and systematic reviews of the literature have shown that this disease is not uncommon. According to these recent studies, the prevalence of RA in Africa is about 0.1 to 0.6% [3-5].

Saline alone vs saline plus mannitol hydration for the prevention of acute cisplatin nephrotoxicity: A randomized trial.

242 Background: Cisplatin is a widely used chemotherapeutic in treating malignancies. A common side effects of cisplatin is kidney injury, or nephrotoxicity. This can be a reason for discontinuation of treatment. The majority of the cisplatin is removed from the body by urination. Mannitol is a compound that has been thought to help negate cisplatin-induced nephrotoxicity. Mannitol is a diuretic, causing increased amount of urination, enhancing excretion of cisplatin. Mmultiple studies that indirectly looked into the effect of mannitol in preventing kidney damage in patients receiving cisplatin. However, there are limited prospective data that evaluate the effect of mannitol in preventing cisplatin-induced nephrotoxicity. In this study, we determine the effects of pre-hydration with mannitol on reducing the risk of cisplatin-induced nephrotoxicity, as opposed to normal saline pre-hydration in patients receiving cisplatin. Methods: 50 patients eligible to receive chemotherapy with cisplatin chemotherapy were identified and randomized to receive 1L saline alone (A) or saline plus mannitol (B) before and after chemotherapy. (1) NS 1 Liter pre chemo- > chemo - > NS 1 Liter post chemo; (2) NS + Mannitol pre chemo - > chemo - > NS + Mannitol post chemo. Serum creatinine and BUN were drawn on days 1 (baseline), 5, and 14 Results: Renal function as measured by BUN/Cr ration, GFR, creatinine, and BUN between group (A) and (B) are similar at baseline (BL), day 1, 5, and 14. Cisplatin caused acute decline in renal function as determined by ser Cr, BUN to ser Cr ratio and GFR, however, the addition of mannitol to NS pre-hydration did not change the outcome. The decline in renal function is limited to grade 1 and most patients recover. Conclusions: Mannitol does not prevent acute nephrotoxicity in patients receiving cisplatin. This underscores the importance of adequate hydration in patients treated with cisplatin. [Table: see text]
Auditive Verarbeitungs- und Wahrnehmungsstörung: Ist die Diagnose schon bei Erstklässlern möglich?

Zusammenfassung Hintergrund Signifikante Leistungsunterschiede zwischen Kindern mit und ohne auditive Verarbeitungs- und Wahrnehmungsstörungen (AVWS) im 2. , 3. und 4. Grundschuljahr wurden in einer eklektischen AVWS-Testbatterie für die meisten Diagnoseinstrumente festgestellt. Die aktuelle Studie erfolgte mit der Fragestellung, ob dies auch für Kinder der 1. Schulklassenstufe zutrifft. Material und Methoden Leistungen von 41 Kindern mit und von 37 ohne AVWS im 1. Regelgrundschuljahr (Alter: 6–8 Jahre) wurden in 14 spezifisch auditiven Tests miteinander verglichen. Ergebnisse Statistisch signifikante Gruppenunterschiede wurden in 12 Diagnoseinstrumenten aufgedeckt; lediglich in 2 PaTSy-Subtests (Tonfrequenzen; Tonintensitäten) war das nicht der Fall. Bzgl. der monauralen Ordnungsschwelle blieb die Signifikanz nach Bonferroni-Korrektur knapp erhalten. Non-AVWS-Kinder bewältigten die PaTSy-Subtests in 86–89 %, AVWS-Kinder in 73–83 % aller Fälle. Die Testwerte von Jungen bzw. Mädchen mit AVWS waren im Vergleich zu denen von Jungen bzw. Mädchen ohne AVWS durchweg reduziert. Schlussfolgerungen Auch Erstklässler mit „AVWS“ ließen sich von solchen ohne „AVWS“ statistisch signifikant unterscheiden. In der Tendenz waren bei Erstklässlern mit AVWS dieselben Leistungen gemindert wie bei Grundschülern in höheren Klassenstufen. Der Einsatz sprachfreier audiologischer Verfahren zur klinischen Diagnose von AVWS erscheint für die Altersgruppe 6–8 Jahre jedoch fragwürdig.

Knowledge-based 3-D object recognition

The organisation of a system for 3-D object recognition by using a knowledge base, is presented. Globally, such a system consists of three major modules, a supervisor which coordinates the other components in order to derive reconstruction of an entire scene, a sensory module and a matchings module. The supervisor communicates with the user of the system through a user interface unit for interactive exchange of information purposes. The second module denoted as sensory provides this information. The third module, indicated as the matching module consists of two components namely the structural and the geometrical matching processes. In our design of the system the structural matching module forms the main idea of the 3D-reconstruction therefore it has the major effort of consideration. The implementation of the supervisor and the structural matching module adopt a knowledge base approach which is explained in detail. <<ETX>>
Social cognitive factors associated with physical activity among university students: a cross-sectional study

The transition from secondary school to university is often accompanied by unhealthy behaviour pattern of decreasing physical activity. The role of social cognitive factors affecting physical activity among university students is not well explored to date. This study was aimed to determine the influence of Self-efficacy, Outcome Expectation for Exercise and Social Support for Exercise Behaviour on physical activity participation among university students. A cross-sectional survey was conducted among university students in Malaysia using a self-reported questionnaire. A total of 390 students participated in the survey. A comprehensive questionnaire was used to collect data from participants on socio-demographic, psychosocial cognitive characteristics and their level of physical activity. Our findings revealed that 63.8 % of participants belong to normal range of body mass index while underweight, overweight and obese are 20.3, 12.3 and 3.6 % respectively. 75.89 % of participants did not meet the recommended vigorous intensity exercise per week. 92.82 % of students participated in less than 5 days of moderate physical activity. Self-efficacy and outcome expectations for exercise had the strongest relations to physical activity; self-efficacy remained the strongest predictor of physical activity. Social support for exercise from family was found to have a weak correlation to physical activity level compared to other variables. Social cognitive factors exert independent effects on physical activity within this population. The findings of this study may facilitate the development of effective and tailored multilevel intervention programs paying more attention to social cognitive factors that will in turn increase physical activity among university students.
Vision-based Quadrotor Micro-UAV Position and Yaw Estimation and Control

This paper describes a novel vision-based position and yaw estimation strategy for quadrotor micro-UAV control for target tracking based on identifying and tracking two points on a target using optic ows. It uses an optimization algorithm and Kalman lters for estimation of quadrotors position and yaw relative to the target. Further position, altitude and heading control of quadrotor are achieved based on vision sensing alone. In addition, experimental results are presented to validate performance of proposed approaches.
Performance evaluation of a channel adaptive WLAN polling protocol

In this paper a wireless local area network (WLAN) with a polling MAC protocol is investigated. This work is the prosecution of an investigation activity on the performance of polling MAC protocols in fading channels, whose preliminary results were presented in Pasolini et al. (2001), and mainly deals with two aspects that Pasolini left open: the performance evaluation with bursty source traffic and the proposal of a channel adaptive MAC protocol solution. As far as the first aspect is concerned, in order to evaluate the impact on the protocol performance (which is measured in terms of mean packet delivery delay against offered traffic) of the source traffic characteristics, we consider both a Poissonian and a bursty traffic distribution. Concerned the second aspect, we introduce the concept of adaptively varying the maximum token holding time (MTHT) as a function of channel fluctuations: the results show that adopting this technique some performance improvements can be found with respect to the case of fixed MTHT.
Kann das CT die Katheterangiografie für die Koronardiagnostik ersetzen? – Ja!

Abstract The guidelines on the management of stable coronary artery disease (SCAD) recommend the use of coronary computed tomography angiography (CTA) in the process of diagnosing coronary artery disease in patients with low intermediate pre-test probability for SCAD. Particularly in cases where stress electrocardiogram or stress imaging provides unclear results, a computed tomographic examination can be considered as a reliable alternative to invasive coronary angiography. Due to its high negative predictive value, coronary CTA can provide accurate information on the presence of coronary artery stenosis and thus coronary artery disease can be reliably excluded without the risks associated with invasive procedures. Similarly, patients with unstable angina or chest pain without typical alterations in the electrocardiogram and without an elevation of troponin can also benefit from a non-invasive coronary CTA-based diagnostics as first approach as it allows ruling out the presence of disease or planning an intervention without the risks associated with a potentially inappropriate invasive approach.
Tiefes Venensystem: Hybridverfahren zur Therapie der iliofemoralen chronischen venösen Obstruktionen

Zusammenfassung Hintergrund Die endovaskuläre Rekanalisation chronischer Verschlüsse der iliofemoralen oder kavalen Venen zeigt vielversprechende Offenheitsraten. Allerdings reduziert sich die Offenheit deutlich, wenn der Verschluss auch die V. femoralis und deren Zuflüsse betrifft. Die Endophlebektomie ermöglicht im Rahmen eines Hybridverfahrens durch Herstellung des Einstroms das Outcome zu verbessern und Frühverschlüsse zu vermeiden. Ziel der Arbeit ist es, die Technik und die bisher veröffentlichten Ergebnisse vorzustellen. Ergebnisse In dem Hybridverfahren erfolgt die venöse Rekanalisation und eine Endophlebektomie als Kombinationseingriff. Bisher liegen nur 4 Publikation mit mehr als 10 Patienten vor mit einem Follow-up zwischen 6 und 24 Monaten. Die primäre bzw. sekundäre Offenheit variiert zwischen 0 und 77% bzw. 30 und 93%. Allerdings wurde bei der überwiegenden Zahl der Patienten eine Verbesserung der klinischen Symptomatik beschrieben. Schlussfolgerung Obwohl nur wenige Daten zum Hybridverfahren und zur Endophlebektomie vorliegen, scheint es diese Technik zu ermöglichen, auch venöse Verschlussprozesse, die bis in den femoralen venösen Zufluss reichen, zu behandeln.
The Relationship Between Eating Disorders and Socioeconomic Status: It's Not What You Think

Author(s): Gibbons, Pat | Abstract: Many people (incorrectly) believe that eating disorders (ED) are more prevalent in the higher socioeconomic status (SES) groups. Studies conducted in the 1960s and 70s corroborate this statement; however, their methods may have biased the results. Recent studies using health questionnaires distributed to large heterogeneous populations have shown that EDs equally effect all people, regardless of SES. These studies have also demonstrated that females of the lower SES group report higher rates of disordered eating behavior (vomiting, use of diet pills, diuretics, or laxatives as a means to lose weight). Girls that exhibit disordered eating behavior are more likely to develop EDs later in life. Physicians need to be aware of this knowledge in order to screen patients for the signs of EDs. More research is necessary to understand why females of low SES employ such methods of weight loss.
Red cell distribution width as biomarker in older adults: a brief review

Submit Manuscript | http://medcraveonline.com strong statistical and independent associations between higher RDW and several diseases such as cardiovascular diseases, diabetes, cancer, pneumonia and gastrointestinal disorders, as well as other acute or chronic conditions, which in turn are present in older adults [4,5]. As RDW is an inexpensive and routine biomarker, with high reproducibility and is widely available in all hematological analyzers, efforts to establish its clinical role could be very valuable for morbidity and mortality risk stratification in older adults.
Enhancing Security and Fine-Grained Access Control for Personal Health Record in Cloud Computing

Now a days , personal health record become patient-centric model in which PHR service allows a patient to manage and control personal health data in one place through the web, which has made the storage, retrieval and sharing of the medical information more efficient . For the wide range access it has out sourced in third party storage such as cloud providers. These PHR contains sensitive data that should be protected from unauthorized parties. But while using third party service providers there are many security and privacy risks for PHR. The one way to protect PHR data is to encrypt data before out sourcing. Since the PHR has been accessed by the multiple authorities; we introduce a fine grained attribute based access control in which each party is assigned with access permission for a set of attributes. Division of personal health records users into multiple security domains which reduce key management complexity for owners and users. A high degree of patient privacy is guaranteed simultaneously by exploiting multi-authority ABE.

Glutenfreie Ernährung – Update 2017

Zusammenfassung Eine glutenfreie Ernährung ist seit 60 Jahren die einzige Therapieoption für Patienten mit Zöliakie oder Dermatitis herpetiformis zur Normalisierung der Beschwerden und Verhinderung von Komplikationen. Eine glutenfreie Ernährung erfreut sich jedoch in jüngster Zeit zunehmender Beliebtheit wegen vermuteter Effekte auf Wohlbefinden und Leistungsfähigkeit sowie zur Kontrolle des Körpergewichts. In der vorliegenden Übersicht wird auf gesicherte Indikationen für eine glutenfreie Ernährung, auf die Notwendigkeit einer eingehenden Beratung und Schulung des Patienten, auf Probleme und Schwierigkeiten bei der Umsetzung einer glutenfreien Ernährung in den täglichen Alltag und auf mögliche Nebenwirkungen unter Langzeittherapie eingegangen. Neue Methoden zur Überprüfung der Adhärenz zu einer glutenfreien Ernährung werden erörtert, die ernährungsmedizinische Qualität etlicher lebensmitteltechnologisch hergestellter glutenfreier Nahrungsmittel wird kritisch diskutiert.
NATURAL LANGUAGE QUERY PROCESSING USING SEMANTIC GRAMMAR

The field of natural language processing (NLP) has seen a dramatic shift in both research direction and methodology in the past several years. In the past, most work in computational linguistics tended to focus on purely symbolic methods. Recently, more and more work is shifting toward hybrid methods that combine new empirical corpus-based methods, including the use of probabilistic and information theoretic techniques, with traditional symbolic methods. The main purpose of Natural Language Query Processing is for an English sentence to be interpreted by the computer and appropriate action taken. Asking questions to databases in natural language is a very convenient and easy method of data access, especially for casual users who do not understand complicated database query languages such as SQL. This paper proposes the architecture for translating English Query into SQL using Semantic Grammar
Realizing Secure Cloud Computing Environment by ECA Rules

Cloud Computing is attracting more and more attention and is becoming the most important paradigm in the new century. However, the security problem has not been solved, which prevents the quick development of cloud computing. This paper proposes how to establish a manageable secure cloud computing environment. The management service for a secure cloud is mainly introduced, among which the security service is specially explained in details. An ECA-rule model is proposed to ensure an automatic activation when security-related events happen. The whole architecture is implemented above Hoodoop which gives the first experience of a secure cloud.
