Entwicklung und Test einer logfilebasierten Metrik zur Analyse von Website Entries am Beispiel einer akademischen Universitäts-Website

Web log files record user transactions on web servers and offer due to their extent, their properties and potential an excellent investigation field for contemporary information and online behaviour studies. The empirical, explorative investigation from the fields Web Mining, Webometrics and Logfile Analysis introduces new aspects and analysis possibilities for web log data. The study develops and tests a quantitative, non-reactive measure method (log metric "Web Entry Factors"), that allows statements about the accessibility and visibility of highly frequented entry points of a web site. The three distinguishable web navigation types "navigation about search engines", "navigation about backlinks" and "direct navigation" are focused. The study integrates a classification scheme for web pages as well as the prominent external parameter PageRank from the today most important search engine Google. Investigation subject are Web log files of two complete age-groups (in 2000 and 2002) of the web server of the Institute for Library Science at the Humboldt University to Berlin (http://www.ib.hu-berlin.de/), as well as the 100 most frequently used entry pages of this academic university web site. This publication goes back to the master thesis in Library and Information Science (Master of Arts, M.A.) at Humboldt-Universitat in Berlin.

Aplicação do Word2vec e do Gradiente descendente dstocástico em tradução automática

Word2vec is a neural network that processes texts and represents words as vectors, using a distributed representation. An important feature are the semantics relationships found in the models generated by it. The aim of this word is to train two models using Word2vec, one for Portuguese and the other for English, and use the stochastic gradient descent to find a translation matrix between those spaces.

A Practical Guide to Sliding and Surface Semilandmarks in Morphometric Analyses

Synopsis Advances in imaging technologies, such as computed tomography (CT) and surface scanning, have facilitated the rapid generation of large datasets of high-resolution three-dimensional (3D) specimen reconstructions in recent years. The wealth of phenotypic information available from these datasets has the potential to inform our understanding of morphological variation and evolution. However, the ever-increasing ease of compiling 3D datasets has created an urgent need for sophisticated methods of capturing high-density shape data that reflect the biological complexity in form. Landmarks often do not take full advantage of the rich shape information available from high-resolution 3D specimen reconstructions, as they are typically restricted to sutures or processes that can be reliably identified across specimens and exclude most of the surface morphology. The development of sliding and surface semilandmark techniques has greatly enhanced the quantification of shape, but their application to diverse datasets can be challenging, especially when dealing with the variable absence of some regions within a structure. Using comprehensive 3D datasets of crania that span the entire clades of birds, squamates and caecilians, we demonstrate methods for capturing morphology across incredibly diverse shapes. We detail many of the difficulties associated with applying semilandmarks to comparable regions across highly disparate structures, and provide solutions to some of these challenges, while considering the consequences of decisions one makes in applying these approaches. Finally, we analyze the benefits of high-density sliding semilandmark approaches over landmark-only studies for capturing shape across diverse organisms and discuss the promise of these approaches for the study of organismal form.

Enhanced hydrodynamic transport in near magic angle twisted bilayer graphene

Using the semiclassical quantum Boltzmann theory and employing the Dirac model with twist angle-dependent Fermi velocity, we obtain results for the electrical resistivity, the electronic thermal resistivity, the Seebeck coefficient, and the Wiedemann-Franz ratio in near magic angle twisted bilayer graphene, as functions of doping density (around the charge-neutrality point) and modified Fermi velocity $\stackrel{\ifmmode \tilde{}\else \~{}\fi{}}{v}$. The $\stackrel{\ifmmode \tilde{}\else \~{}\fi{}}{v}$ dependence of the relevant scattering mechanisms, i.e., electron-hole Coulomb, long-range impurities, and acoustic gauge phonons, is considered in detail. We find a range of twist angles and temperatures, where the combined effect of momentum-nonconserving collisions (long-range impurities and phonons) is minimal, opening a window for the observation of strong hydrodynamic transport. Several experimental signatures are identified, such as a sharp dependence of the electric resistivity on doping density and a large enhancement of the Wiedemann-Franz ratio and the Seebeck coefficient.
DENTAL CARIES AND LACTOBACILLUS: ROLE AND ECOLOGY IN THE ORAL CAVITY

Dental caries is an infective serious transmittable bacterial disease characterized by a multi-factorial pathology. Main players in the etiology of this disease are cariogenic bacteria, fermentable carbohydrates, a susceptible tooth, the host, and the time. It is still one of the most common disease worldwide. Biological factor such as cariogenic bacteria plays an important role in dental caries initiation, progression as well as tooth decay. Previous studies suggested that the main pathogenic bacteria are Streptococcus mutans and Lactobacillus. Consequently, Lactobacillus is considered the second most cariogenic bacteria of oral flora. It is not the caries initiator but plays an important role in caries progression. Most of the previous studies were quantitative, so till now, researchers not know about the specific species of Lactobacillus which are directly associated with dental caries progression. Some species-level identification studies suggested that the most common Lactobacillus species are L. gasseeri, L. fermentum, L. vaginalis and L. casei which were predominantly reported at the most of the oral sites, i.e. saliva, tongue, carious lesion, dental plaque, etc. and maybe plays the main role in caries progression. The present review spotlights the role, pathogenicity of Lactobacillus in dental caries and their ecology in the
Prevalence, Severity, and Impacts of Premenstrual Syndrome among Female Medical Students at Taibah University in Saudi Arabia

Background: The premenstrual syndrome (PMS) is particularly common in the younger age groups and, therefore represents a significant public health problem in young girls. This study aims to estimate the prevalence of PMS, and determine its severity and impacts among female medical students at Taibah University in AlMadina Al-Munawarah city, Saudi Arabia. Methods: This is cross sectional study, two different questionnaires covering American College of Obstetrics and Gynaecology (ACOG) criteria to diagnose PMS, demographic & reproductive factors, physical activity have been distributed over all 1 st and 2 nd year medical female students at Taibah University, where 81.2% have returned completed questionnaires. Results: Premenstrual syndrome was prevalent in 56.4% of participating students. No significant differences (p<0.05) have been found between students with PMS and those without PMS regarding effect of premenstrual period on student's academic & social life (perceived effect on overall academic life, lectures attendance, grades, social activities, and sleep rhythm), however students with PMS perceived effect of premenstrual period on overall academic life more than those with no PMS (40.9%vs. 35.3%). Conclusion: we concluded that although PMS prevalent among medical students at Taibah University in Saudi Arabia, it is not a significant problem.
Stratosphere–Troposphere Exchange and O3 Decline in the Lower Stratosphere over Irene SHADOZ Site, South Africa

This study aims to investigate the Stratosphere-Troposphere Exchange (STE) events and ozone trends over Irene (25.5°S, 28.1°E). Twelve years of ozonesondes data (2000–2007, 2012–2015) from Irene station operating in the framework of the Southern Hemisphere Additional Ozonesodes (SHADOZ) was used to study the troposphere (0–16 km) and stratosphere (17– 28 km) ozone (O3) vertical profiles. Ozone profiles were grouped into three categories (2000–2003, 2004–2007 and 2012– 2015) and average composites were calculated for each category. Fifteen O3 enhancement events were identified over the study period. These events were observed in all seasons (one event in summer, four events in autumn, five events in winter and five events in spring), however, they predominantly occur in winter and spring. The STE events presented here are observed to be influenced by the Southern Hemisphere polar vortex. During the STE events, the advected potential vorticity maps assimilated using Modélisation Isentrope du transport Méso–échelle de l’Ozone Stratosphérique par Advection (MIMOSA) model for the 350 K (~12–13 km) isentropic level indicated a transport of high latitude air masses which seems to be responsible for the reduction of the O3 mole fractions at the lower stratosphere over Irene which takes place at the same time with the enhancement of ozone in the upper troposphere. In general, the stratosphere is dominated by higher Modern Retrospective Analysis for Research Application (MERRA-2) potential vorticity (PV) values compared to the troposphere. However, during the STE events, higher PV values from the stratosphere were observed to intrude the troposphere. Ozone decline was observed from 12 km to 24 km with highest decline occurring from 14 km to 18 km. An average decrease of 6.0 and 9.1% was calculated from 12 to 24 km in 2004–2007 and 2012–2015 respectively. The observed decline occurred in the upper troposphere and lower stratosphere with winter and spring showing more decline compared with summer and autumn.
Efeito Antialimentar do Extrato Metanólico de Annona crassiflora Mart. sobre o Percevejo Marrom Euschistus heros (Fabr. 1798) (Heteroptera: Pentatomidae)

O objetivo deste trabalho foi avaliar a acao do extrato metanolico de Annona crassiflora (Mart.) sobre adultos de Euschistus heros (Fabr.) em laboratorio. O experimento foi conduzido no Laboratorio de Entomologia da Universidade do Estado de Mato Grosso, UNEMAT, Campus de Tangara da Serra. Para avaliar a acao anti-alimentar do extrato foram utilizados 160 adultos de E. heros com dois dias de idade e 24h sem alimentacao. Foram utilizadas tres concentracoes de extrato metanolico de A. crassiflora nas concentracoes de 1,0; 2,0 e 4,0% e o controle (DMSO-Dimetilsulfoxido 40%). Cada tratamento teve quatro repeticoes com 10 casais cada um. As vagens foram mergulhadas por 30 segundos em cada tratamento, e secas ao ar livre por 1 hora. Apos esse periodo foram oferecidas aos adultos por 48h. Posteriormente, as vagens foram retiradas e mergulhadas em fucsina acida, em seguida em agua e secas ao ar livre. Depois de eliminado o excesso de agua foi efetuada a contagem dos pontos de alimentacao na superficie externa da vagem, na superficie interna e na semente. Foram tambem avaliadas a mortalidade dos percevejos. Os dados coletados foram submetidos a analise de variância (ANOVA) e as medias comparadas pelo teste de Scott Knott a 5% de probabilidade, por meio do aplicativo estatistico SAEG. A alimentacao dos adultos foi significativamente reduzida em vagens tratadas comparadas com a testemunha, baseados na contagem dos pontos de alimentacao na superficie das vagens, na face interna e nas sementes. A acao anti-alimentar do extrato de A. crassiflora foi significativamente maior nas vagens tratadas com extrato metanolico a 4,0% do que a 2,0% e 1,0%. O extrato de semente de A. crassiflora pode ser uma ferramenta no manejo de combate ao E. heros.

The Information Content Of Annual Earnings Announcements

The information content of earnings is an issue of obvious importance and is a focal point for many measurement controversies in accounting. This paper empirically examines the extent to which common stock investors perceive earnings to possess informational value. The study directs its attention to investor reaction to earnings announcements, as reflected in the volume and price movements of common stocks in the weeks surrounding the announcement date. Valuation theory has long posited a relationship between earnings and the value of common stock. Miller and Modigliani postulate that one important element in determining the value of common stock is the product of earnings times the appropriate earnings multiplier for that risk class. ' Graham, Dodd, and Cottle take a similar position with respect to the computation of their "intrinsic value" of common stock securities.2 MM also provide empirical evidence that suggests if reported earnings are adjusted for measurement errors through the use of instrumental variables, the adjusted earnings are useful in the prediction of the market value of electric utility firms. In fact, the evidence indicated that the earnings term was the most important explanatory variable in the valuation equation.3 The relationship is a necessary condition for earnings to have information content,
Predictors and in-hospital outcomes of cardiogenic shock on admission in patients with acute coronary syndromes admitted to hospitals without on-site invasive facilities

Abstract Background: The purpose was to identify predictors of cardiogenic shock (CS) on admission and to asses associations between CS and real-life management patterns and outcomes in unselected cohort of acute coronary syndrome (ACS) patients admitted to hospitals without onsite invasive facilities. Methods: Data concerning in-hospital management and mortality of 56 (4.3%) patients with and 1257 (95.7%) without CS on hospital admission was assessed. Results: Prior myocardial infarction, prior heart failure symptoms, age, and diabetes mellitus were independently associated with increased risk of CS on admission. A total of 23.8% patients were transferred for invasive treatment during index hospital stay and the frequency of transfer was similar among patients with and without CS on admission (21.4% versus 23.9%; P = 0.75), but in the STEMI subgroup, patients with shock were transported less frequently (21.4% versus 43.8%; P = 0.0027). CS patients were less likely to receive guideline-recommended therapies including antiplatelet drugs, statins, and beta-blockers. In-hospital mortality was lower in non-shock patients (6.2% versus 63.6%; P < 0.001) and CS on admission was an independent predictor of in-hospital death. Conclusions: CS on admission is an important determinant of treatment strategy selection and is associated with unfavorable prognosis of ACS patients admitted to hospitals without on-site invasive facilities.
Diffuse ecchymoses and blisters on a yellowish waxy base: A case of bullous amyloidosis

KL-6 as a marker of IP was high (2149 U/mL; normal range, 0–499), the patient had no clinical symptoms of respiratory disease. In addition, chest computed tomography (CT) (Fig. 1) showed no interstitial shadows such as shown in usual IP or a non-specific IP, and there was no consolidation in the lobe. After two administrations of UST, she developed a clinical symptom of a cough and the serum KL-6 was elevated to 6809 U/mL. The b-D-glucan was normal and systemic CT showed no malignancy in the internal body. A chest CT revealed consolidation shadows in both lobes. Respiratory physicians consulted about the symptom diagnosed IP. After discontinuation of UST, the consolidation shadows on the lung had diminished and KL-6 had decreased to the initial level. From these findings, we concluded the respiratory phenomenon was UST-induced IP. In case 2, a 60-year-old man had a 10-year history of psoriasis. Before administration of UST, IFX and cyclosporin had been used, however, they had been discontinued due to infusion reaction or insufficient efficacy. UST was then begun, and the initial serum KL-6 level was 1046 U/mL. He had no risk factor such as elderliness, diabetes mellitus or low albumin. After 2 years of treatment with UST, the serum KL-6 was elevated to 2149 U/mL. Systemic CT showed no malignancy in the internal body and chest CT showed consolidation shadows in the left lobe which a respiratory physician diagnosed as IP. Since the use of UST has been discontinued, the shadows have diminished and KL-6 has decreased to the initial level. Little is known regarding the mechanism of UST-induced IP. Although there are some reports of anti-TNF-a agent-induced IP, it is difficult to prove that these agents actually cause this condition. In both cases, there were similar points of a high KL-6 level at the initiation of treatment with UST. We have treated approximately 200 patients who received UST. There were three patients showing KL-6 of more than 1000 ng/mL in patients who were treated within our institution. IP developed in two of them. After discontinuation of UST, at least a period of 6 months was needed to return to baseline in the level of KL-6. To detect the increase of KL-6, blood examination should be performed every 3 months during treatment.
