Identifying Informative Messages in Disasters using Convolutional Neural Networks

Social media is a vital source of information during any major event, especially natural disasters. Data produced through social networking sites is seen as ubiquitous, rapid and accessible, and it is believed to empower average citizens to become more situationally aware during disasters and coordinate to help themselves. However, with the exponential increase in the volume of social media data, so comes the increase in data that are irrelevant to a disaster, thus, diminishing peoples’ ability to find the information that they need in order to organize relief efforts, find help, and potentially save lives. In this paper, we present an approach to identifying informative messages in social media streams during disaster events. Our approach is based on Convolutional Neural Networks and shows significant improvement in performance over models that use the “bag of words” and n-grams as features on several datasets of messages from flooding events.
LEVERAGING EMPLOYEE ENGAGEMENT FOR COMPETITIVE ADVANTAGE: HR'S STRATEGIC ROLE

Employee engagement is a key business driver for organizational success. High levels of engagement in domestic and global firms promote retention of talent, foster customer loyalty and improve organizational performance and stakeholder value. A complex concept, engagement is influenced by many factors—from workplace culture, organizational communication and managerial styles to trust and respect, leadership and company reputation. For today’s different generations, access to training and career opportunities, work/life balance and empowerment to make decisions are important. Thus, to foster a culture of engagement, HR leads the way to design, measure and evaluate proactive workplace policies and practices that help attract and retain talent with skills and competencies necessary for growth and sustainability.
Hypertension Produced by Choline Deficiency in Rats

&NA; Choline deficiency has been produced in young rats and some factors which affect the resulting hypertension have been studied. A micro‐sphygmomanometric apparatus was devised to measure blood pressures which were found to rise after 7–10 days on the choline deficient diet to values 25–35 mm. Hg. higher than those of supplemented rats. Rat blood pressures were measured for 14 wk. after adequate choline supplements were re‐introduced into the diet and the hypertension persisted for that length of time. Replacement of drinking water by 1 % NaCI solution produced a further increase of 8‐25% in the blood pressure of choline deficient rats. Hypertension was prevented by injection of ethyl trichloracetate or by periods of partial immersion of the rats in water. Injections of phenoxybenzamine decreased the blood pressure of choline deficient rats to that of supplemented rats over the period of administration.
Influences of different combinations of conceptual, perceptual, and structural similarity on stimulus-response compatibility

This study evaluated the hypothesis that an increase in set-level stimulus-response compatibility produces facilitation for congruent mappings and interference for incongruent mappings. The degree of set-level compatibility was manipulated by varying combinations of conceptual, perceptual, and structural similarity. Experiment 1 varied perceptual similarity, by combining two stimulus codes (spatial, verbal) with two response modalities (manual, vocal) for orthogonal spatial dimensions, which have structural similarity. The element-level mapping effect did not vary as a function of the code-modality relation, in contrast to findings obtained with parallel spatial dimensions, which also have conceptual similarity. Experiment 2 manipulated combinations of conceptual and perceptual similarity by combining vertical and horizontal stimulus and response orientations, using verbal or spatial stimuli and vocal responses. The element-level mapping effect was larger for parallel than orthogonal orientations, with congruent mappings showing facilitation and incongruent mappings showing interference. The largest effect was facilitation for parallel orientations with the verbal-vocal set, consistent with the view that perceptual similarity contributes to performance primarily when responding with the identity of the stimulus. Our results indicate that conceptual similarity, but not perceptual similarity, produces the facilitation/interference pattern suggestive of automatic activation of the corresponding response regardless of mapping.
Current Concepts on Anatomy and Biomechanics of Patellar Stability

This review describes anatomic features of the patellofemoral joint that relate to the stability and function of the joint. The role of the geometry of the articular surfaces, particularly the trochlear groove, it's depth and orientation, are described. The stabilizing actions of the medial and lateral retinaculae, that tether the patella from either side to guide it into the trochlear groove in the early phase of knee flexion, are related to the specific structures, the medial patellofemoral ligament, and the fibers originating from the ilio-tibial tract laterally. The quadriceps muscles have different orientations, and converge onto the patella not only from either side but also from posteriorly, thus pulling the patella onto the anterior aspect of the trochlea. Finally, these local factors are discussed in relation to overall limb alignment, which leads to the mechanical logic of more extensive surgical procedures such as femoral rotational osteotomy or tibial tuberosity medialization.
VulDeePecker: A Deep Learning-Based System for Vulnerability Detection

The automatic detection of software vulnerabilities is an important research problem. However, existing solutions to this problem rely on human experts to define features and often miss many vulnerabilities (i.e., incurring high false negative rate). In this paper, we initiate the study of using deep learning-based vulnerability detection to relieve human experts from the tedious and subjective task of manually defining features. Since deep learning is motivated to deal with problems that are very different from the problem of vulnerability detection, we need some guiding principles for applying deep learning to vulnerability detection. In particular, we need to find representations of software programs that are suitable for deep learning. For this purpose, we propose using code gadgets to represent programs and then transform them into vectors, where a code gadget is a number of (not necessarily consecutive) lines of code that are semantically related to each other. This leads to the design and implementation of a deep learning-based vulnerability detection system, called Vulnerability Deep Pecker (VulDeePecker). In order to evaluate VulDeePecker, we present the first vulnerability dataset for deep learning approaches. Experimental results show that VulDeePecker can achieve much fewer false negatives (with reasonable false positives) than other approaches. We further apply VulDeePecker to 3 software products (namely Xen, Seamonkey, and Libav) and detect 4 vulnerabilities, which are not reported in the National Vulnerability Database but were "silently" patched by the vendors when releasing later versions of these products; in contrast, these vulnerabilities are almost entirely missed by the other vulnerability detection systems we experimented with.
Depressive symptoms among poor older adults in Mexico: prevalence and associated factors.

OBJECTIVE To describe the presence of depressive symptoms (DS) and factors associated with them among poor Mexican older male and female adults (OA). METHODS A survey was conducted among OA enrolled in a governmental poverty relief program (Oportunidades) in Mexico. Participants completed a short version of the Center for Epidemiologic Studies Depression Scale and answered questions about health and life conditions. RESULTS The prevalence of DS over the cutoff point was 43% (confidence interval (CI) 39.5-46.4). DS were associated with different variables among male and female participants. For men, difficulties in performing daily life activities were associated with DS over the cutoff point (odds ratio (OR) 2.62, CI 1.58-4.34) and literacy was associated with less DS (OR 0.46, CI 0.31-0.68). For women, difficulties with daily life activities were associated with more DS (OR 2.50, CI 1.57-3.97), and being head of the family was also positively associated (OR 1.81, CI 1.11-2.93). CONCLUSIONS DS were frequent among this sample of poor OA. The differences between men and women in variables associated with DS highlight the importance of considering the gendered aspects of growing old.
A 0.9-V 60-$\mu{\hbox {W}}$  1-Bit Fourth-Order Delta-Sigma Modulator With 83-dB Dynamic Range

A 0.9-V 60-muW delta-sigma modulator is designed using standard CMOS 0.13-mum technology. The modulator achieves 83-dB dynamic range in a signal bandwidth of 20 kHz with a sampling frequency of 2 MHz. The input-feedforward architecture is used to reduce the voltage swing of the integrators, which enables low-power amplifiers. By considering the characteristics of the modulator architecture, low-quiescent operational transconductance amplifiers are designed, which use positive feedback to increase dc gain. The designed modulator shows very high figure of merit among the state-of-the-art sub-l-V modulators.
PHYLOGENETIC ANALYSIS OF CORRELATION STRUCTURE IN STALK‐EYED FLIES (DIASEMOPSIS, DIOPSIDAE)

Abstract. — Morphological divergence among species may be constrained by the pattern of genetic variances and covariances among traits within species. Assessing the existence of such a relationship in nature requires information on the stability of intraspecific correlation and covariance structure and the correspondence of this structure to the pattern of evolutionary divergence within a lineage. Here, we investigate these issues for nine morphological traits and 15 species of stalk‐eyed flies in the genus Diasemopsis. Within‐species matrices for these traits were generated from phenotypic data for all the Diasemopsis species and from genetic data for a single Diasemopsis species, D. dubia. The among‐species pattern of divergence was assessed by calculating the evolutionary correlations for all pairwise combinations of the morphological traits along the phylogeny of these species. Comparisons of intraspecific matrices reveal significant similarity among all species in the phenotypic correlations matrices but not the covariance matrices. In addition, the differences in correlation structure that do exist among species are not related to their phylogenetic placement or change in the means of the traits. Comparisons of the phenotypic and phylogenetic matrices suggest a strong relationship between the pattern of evolutionary change among species and both the intraspecific correlation structure and the stability of this structure among species. The phenotypic and the phylogenetic matrices are significantly similar, and pairs of traits whose intraspecific correlations are more stable across taxa exhibit stronger coevolution on the phylogeny. These results suggest either the existence of strong constraints on the pattern of evolutionary change or a consistent pattern of correlated selection shaping both the phenotypic and phylogenetic matrices. The genetic correlation structure for D. dubia, however, does not correspond with patterns found in the phenotypic and phylogenetic data. Possible reasons for this disagreement are discussed.
Atividade Antimicrobiana In Vitro de Extratos Alcoólicos de Própolis contra Elsinoe ampelina

O principal metodo de controle para patogenos da videira e a aplicacao de fungicidas. Dessa forma, a adocao de metodos alternativos de controle pode reduzir os custos de producao e minimizar os residuos quimicos nos frutos. Objetivou-se com este trabalho verificar a fungitoxicidade in vitro de extratos alcoolicos de propolis (EAP) sobre o crescimento micelial e esporulacao de esporos de Elsinoe ampelina (antracnose). O EAP foi utilizado nas concentracoes de 0,05; 0,1; 0,2; 0,4; 0,5 e 1,0%, diluidas com caldo de batata. As testemunhas foram o meio de cultura BDA, BDA + 1% de etanol a 70% e o fungicida azoxystrobin (0,08 g i.a. L-1). Na esporulacao de E. ampelina, o fungicida e a concentracao de 0,5% de EAP foram os tratamentos mais eficientes, porem sem diferenca estatistica entre si. No ensaio de crescimento micelial, a inibicao media causada por EAP foi de 15%, inferior a inibicao de 48% causada pelo fungicida.
Peyronie’s penile plication

Penile plication has become the preferred surgical technique for Peyronie’s disease (PD) as it can be performed efficiently, safely, with a high success rate, low morbidity and a low complication rate. Here in we describe two modern plication techniques in detail: the Kiels Knot plication and the minimally invasive penoscrotal plication. Benefits of the techniques include no palpable sutures for the Kiels Knot Plication and less surgical trauma for the penoscrotal plication. Plication has a low rate of failure. However, when it does occur it is usually secondary to under-correction. Failures typically present early postoperatively and a contributing factor to underestimating the deformity is a poor intraoperative artificial erection. Complex, severe, or multiplanar deformities will require more sophisticated intraoperative decision-making, but can be managed effectively with penile plication nonetheless.
Ketoprofen (19.583 R.P.) (2-(3-benzoylphenyl)-propionic acid). Main pharmacological properties--outline of toxicological and pharmacokinetic data.

Ketoprofen possesses the typical pharmacological properties of non-steroidal anti-inflammatory agents i.e. anti-inflammatory, analgesic and antipyretic activity, as well as antibradykinin activity and ability to inhibit prostaglandin synthesis. Ketoprofen is as potent as indomethacin in the tests for anti-inflammatory and analgesic activity, but its antipyretic and antibradykinin activities and its inhibitory activity against prostaglandin synthesis is respectively 4, 8 and 8 times greater than that of indomethacin. It seems very likely that the pituitary-adrenal axis is not involved in the mechanism of the anti-inflammatory action of ketoprofen, since in the carrageenan abscess test, the compound shows the same activity both in adrenalectomized and in normal rats and, when locally applied to the inflamed area, it is more active than when administered systemically. In the mouse the acute oral toxicity of ketoprofen is about one twentieth that of indomethacin. Like all powerful steroidal or non-steroidal antiinflammatory agents, ketoprofen shows some gastrointestinal toxicity, but its effect is mild and distinctly less than that of indomethacin. Pharmacokinetic studies in the rat, dog and monkey have shown that gastro-intestinal absorption of the drug is rapid and almost complete; the compound and its metabolites are excreted from the body fairly rapidly.
Root‐analogue versus crown‐analogue dentin: A radioautographic and ultrastructural investigation of the mouse incisor

The present paper reports on differences between the root‐ and crown‐analogue dentin portions of the continuously growing mouse incisor. Conventional light microscopy and radioautography were used to study dentin formation and the uptake of [3H]‐proline and [3H]‐serine. It was found that, although the dentin apposition rate along the crown‐analogue part (covered by enamel) equalled or slightly exceeded that along the root‐analogue part (covered by cementum), the processing of predentin into dentin was considerably faster in the root aspect.
Gender differences in help-utilization and the 8-year course of alcohol abuse.

AIMS The aim of this study was to compare initially untreated women and men problem drinkers on help-utilization and outcomes over 8 years. DESIGN AND PARTICIPANTS At the time of the 8-year follow-up, individuals (N=466, 49% female) had self-selected into four groups: no help, Alcoholics Anonymous (AA) only, formal treatment only or formal treatment plus AA. MEASUREMENTS At baseline and 1, 3 and 8 years later, participants completed measures of drinking and functioning. FINDINGS Women were generally worse off than men on baseline drinking and functioning indices. In keeping with their poorer baseline status, women were more likely to participate in AA, and had longer in-patient stays during the next year. When women's baseline status was controlled, women had better outcomes than did men at 1 and 8 years. Generally, women and men did not differ on the extent to which obtaining help, or a particular type of help, was related to improved outcomes. Regarding drinking outcomes, women benefited more than did men from more AA attendance during years 2-8 of follow-up. CONCLUSIONS The results suggest that although alcoholism interventions were designed primarily for men, they are currently delivered in ways that are also useful to women. Problem-drinking women appear to benefit from sustained participation in AA, which emphasizes bonding with supportive peers to maintain abstinence.
Spatial Correlation Analysis of the Pharmacological Conversion of Sustained Atrial Fibrillation in Conscious Goats by Cibenzoline

The nonlinear spatial redundancy and the linear spatial correlation function were used to investigate to what extent non-linearity was involved in the coupling of atrial regions and how organization in activation patterns of sustained atrial fibrillation (AF) had been modified by administration of the class IC agent cibenzoline in the experimental model of sustained AF in instrumented conscious goats. Electrograms were measured in five goats during sustained AF and when the fibrillation interval had been prolonged to about 25%, 50% and 85% (CIB25, CIB50, CIB85) with respect to control. The nonlinear association length and linear correlation length were estimated along the principal axes of two-dimensional correlation maps estimated from the spatial redundancy and the spatial correlation function, respectively. The estimated short axis association length in the right atrium increased already shortly after the start of infusion (CIB25, +61%), and remained significantly different from control during the experiment, including the effects of non-simultaneous interaction. At CIB85 the association length had almost become twice as long with respect to control (increase from 16 to 29 mm, 89%), while in the left atrium changes were less pronounced (increase from 9 to 12 mm, +32%). The linearized association length which was estimated using multivariate surrogate data increased more gradually and was less sensitive to changes in spatial organization. The results of the spatial correlation analysis suggest that the drug-induced nonlinearity in the spatio-temporal dynamics of sustained AF is related to activation patterns which are characterized by extended uniformly propagating fibrillation wavefronts (AF type I). We conclude that cibenzoline enhanced the spatial organization of sustained AF associated with a transition from type II to type I AF activation patterns. This may destabilize the perpetuation of AF since an increase in association length is equivalent to a reduction of atrial tissue mass available to support reentrant circuits. The results are consistent with the hypothesis that larger association lengths result from fewer and larger reentrant circuits. It is argued that effects of diminished curvature of fibrillation wavefronts are anti-arrhythmic under conditions of suppressed excitability imposed by cibenzoline. Termination of AF may be mediated by a mechanism resembling a bifurcation of the dynamics which sets in when the ends of fractionated wavefronts cannot sufficiently curve anymore to maintain a positive balance of newly generated wavelets needed to sustain AF.
Continuous Probabilistic Prediction of Angiographically Significant Coronary Artery Disease Using Electron Beam Tomography

Background—We sought to incorporate electron beam tomography–derived calcium scores in a model for prediction of angiographically significant coronary artery disease (CAD). Such a model could greatly facilitate clinical triage in symptomatic patients with no known CAD. Methods and Results—We examined 1851 patients with suspected CAD who underwent coronary angiography for clinical indications. An electron beam tomographic scan was performed in all patients. Total per-patient calcium scores and separate scores for the major coronary arteries were added to logistic regression models to calculate a posterior probability of the severity and extent of angiographic disease. These models were designed to be continuous, adjusted for age and sex, corrected for verification bias, and independently validated in terms of their incremental diagnostic accuracy. The overall sensitivity was 95%, and specificity was 66% for coronary calcium to predict obstructive disease on angiography. With calcium scores >20, >80, and >100, the sensitivity to predict stenosis decreased to 90%, 79%, and 76%, whereas the specificity increased to 58%, 72%, and 75%, respectively. The logistic regression model exhibited excellent discrimination (receiver operating characteristic curve area, 0.842±0.023) and calibration (&khgr;2 goodness of fit, 8.95;P =0.442). Conclusions—Electron beam tomographic calcium scanning provides incremental and independent power in predicting the severity and extent of angiographically significant CAD in symptomatic patients, in conjunction with pretest probability of disease. This algorithm is most useful when applied to an intermediate-risk population.
The influence of lead and cadmium environmental pollution on anthropometric health factors in children.

THE AIM The aim of the study was to examine the relationship between environment pollution (lead and cadmium) and selected anthropological factors. MATERIAL AND METHODS The study group comprised 267 children, aged 11 +/- 0.4. Blood sampling and anthropological measurements were carried out in Kraków (polluted area) and in the Krosno region (low polluted area) in 1995. The lead and cadmium concentrations in the whole blood were determined using atomic absorption spectrometry with a graphite furnace and automatic dosage. The anthropometric measurements were made at the same time as the blood collection. RESULTS The blood lead content in boys and girls was: 5.89 +/- 2.54, 5.01 +/- 1.62 micrograms/dl respectively, and the cadmium blood content was: 0.65 +/- 0.30, 0.68 +/- 0.47 microgram/l. Body mass and height did not correlate with lead and cadmium concentrations in the children's blood. Smaller head circumferences, independently of gender, were associated with a higher cadmium level. The values of four skin-folds (on the arm: biceps, triceps, under scapular bone and above iliac crest), as well as the percentage of fat content in the organism (PFDWB) calculated by the Slaughter-Lohman equation was higher in girls than in boys. CONCLUSIONS 1. The relationships between cadmium and lead blood levels in children on the one hand and the degree of environmental pollution with these metals, and the gender of the children on the other were observed. The boys accumulated more lead, whereas the girls absorbed more cadmium. 2. Anthropometric analysis did not show a significant influence exerted by the polluted environment on the basic auxological parameters. In the group of children examined, the only differences observed were related to gender, head circumferences and indicators of obesity.
