An Arabic semantic search engine for large governmental organization

Large organizations contain huge structured and unstructured data. This data need to be analyzed and retrieved as a part of their daily business. Data extractor that depends on entity recognition to extract data from documents and converts it into structured database can solve the problem of searching in unstructured data. In addition, semantic search engines that use query expansion to extract results that are more informative can solve the problem of polysemy and synonymy. This paper proposes a complete solution to solve these problems. An Arabic semantic search engine is proposed which consists of four components (data extractor, taxonomy builder, database indexer, and search engine). The system is applied on a real case study of a large governmental organization's database. The results show superior performance compared to other solutions. It gives good measures for the F-score and gives a mean average precision of 0.8.
Cross-shift airway responses and long-term decline in FEV1 in cotton textile workers.

RATIONALE Acute airway response, measured as cross-shift change in FEV(1), to cotton dust may lead to subsequent chronic loss of lung function in exposed workers. OBJECTIVES To explore the association between the magnitude and frequency of cross-shift change and chronic loss of FEV(1). METHODS Four hundred eight cotton workers and 417 silk workers from Shanghai textile mills were observed prospectively for 20 years, with cross-shift measurements at baseline and follow-up surveys at approximate 5-year intervals. To account for repeated measures of 5-year change, generalized estimating equations were used to estimate the relationship between the magnitude of cross-shift change in FEV(1) (DeltaFEV(1)) and subsequent 5-year annualized change. Linear regression models were used to examine the association between the number of drops in cross-shift FEV(1) (DeltaFEV(1) < 0) and annualized change over the entire study period. MEASUREMENTS AND MAIN RESULTS Exposure to cotton dust was associated with a 10 ml/year decrement in 5-year annualized FEV(1) decline. In addition, every 10 ml in DeltaFEV(1) drop was associated with an additional 1.5 ml/year loss in annualized FEV(1) decline. The association between the frequency of drops and annualized decline was stronger for cotton workers than for silk workers over the entire study period. CONCLUSIONS Cotton workers had larger and more frequent drops, as well as excessive chronic declines in FEV(1), than did silk workers. The magnitude and frequency of cross-shift drops were associated with chronic loss in FEV(1) over the entire 20-year period examined.
Study of Guessability method in a game for multitouch screen

One of the elements of an application for touch-based devices is the vocabulary of gestures. There are methods for creating a vocabulary of gestures that are intuitive and considered ergonomically good. In order to assess the quality of one of these methods, a test with the Guessability method was performed using a game for multi-touch screen. The test showed the potential of this method being generic enough to work with different sorts of applications, allowing a great amount of freedom in its execution. Yet, this freedom brought along some problems which must be taken into consideration or modified before using the Guessability method.
Cardiomyopathy in children with Down syndrome treated for acute myeloid leukemia: a report from the Children's Oncology Group Study POG 9421.

PURPOSE To determine the outcomes, with particular attention to toxicity, of children with Down syndrome (DS) and acute myeloid leukemia (AML) treated on Pediatric Oncology Group (POG) protocol 9421. PATIENTS AND METHODS Children with DS and newly diagnosed AML (n = 57) were prospectively enrolled onto the standard-therapy arm of POG 9421 and were administered five cycles of chemotherapy, which included daunorubicin 135 mg/m(2) and mitoxantrone 80 mg/m(2). Outcomes and toxicity were evaluated prospectively and were compared with the non-DS-AML cohort (n = 565). A retrospective chart review was performed to identify adverse cardiac events. RESULTS In the DS-AML group, 54 patients (94.7%) entered remission. One experienced induction failure and two died. Of the 54 who entered remission, three relapsed and six died as a result of other causes. The remission induction rate was similar in the non-DS-French-American-British (FAB) M7 (91.7%) and non-DS-non-M7 (89.3%) groups. The 5-year overall survival was significantly better in the DS-AML group (78.6%) than in the non-DS-M7 (36.3%) or the non-DS-non-M7 (51.8%) groups (P < .001). No age-related difference in 5-year, event-free survival was seen between patients younger than 2 years (75.8%) and those aged 2 to 4 years (78.3%). Symptomatic cardiomyopathy developed in 10 patients (17.5%) with DS-AML during or soon after completion of treatment; three died as a result of congestive heart failure. CONCLUSION The POG 9421 treatment regimen was highly effective in both remission induction and disease-free survival for patients with DS-AML. However, there was a high incidence of cardiomyopathy, which supports current strategies for dose reduction of anthracyclines in this patient population.
A preliminary study of inflammatory markers in non-alcoholic steatohepatitis patients

It was reported that C-reactive protein (CRP) levels increase in parallel with the progression of chronic liver diseases, such as chronic hepatitis and liver cirrhosis. Inflammatory markers, such as high sensitive C-reactive protein (hsCRP), ferritin, transferrin, albumin, alpha-1 acid glycoprotein (AAG), alpha-2 macroglobulin (AMG), alpha-1 anti-trypsin (AAT) and lipoprotein a [Lp(a)] were measured in coronary artery disease patients (CAD) and CAD patients with non-alcoholic steatohepatitis (NASH). In the present preliminary study an attempt was made to study whether there is an increase in the levels of CRP in CAD patients associated with NASH. CAD patients showed an increase in CRP and serum ferritin levels. In CAD patients with NASH along with an increase in the levels of serum ferittin (p<0.001), the levels of serum AMG and ceruloplasmin (CP) were also increased (p<0.01). The CAD patients with NASH had a higher proportion of diabetes, hypertension and dyslipidaemia compared to CAD patients. But how this difference contributes to the elevation in acute inflammatory markers particularly AMG and CP levels in CAD patients with NASH cannot be explained. This study shows that a substantial number of CAD patients may be associated with NASH. Non-invasive simple parameters that reflect the degree of inflammation and fibrosis of the liver in patients with NASH would facilitate improved understanding and treatment of the disease. Further studies may be necessary to evaluate the percentage of NASH patients progressing to CAD.
[Interobserver agreement in the assessment of pulmonary infiltrates on chest radiography in community-acquired pneumonia].

PURPOSE To assess interobserver agreement (IOA) in the diagnosis of pulmonary infiltrates on chest x-rays for patients with community-acquired pneumonia (CAP). MATERIALS AND METHODS From 7/2002 to 12/2005, 806 adults with CAP were included in the multicenter study "CAPNETZ" (7 hospitals). Inclusion criteria were clinical signs of pneumonia and pulmonary opacification on chest x-rays. Each x-ray was reevaluated by two radiologists from the university hospital in consensus reading against the interpreter at the referring hospital in regard to: presence of infiltrate (yes/no/equivocal), transparency (<or=/>50%), localization, and pattern of infiltrates (alveolar/interstitial). The following parameters were documented: digital or film radiography, hospitalization, fever, findings of auscultation, microbiological findings. RESULTS The overall IOA concerning the detection of infiltrates was 77.7% (n=626; CI 0.75-0.81), the infiltrates were not verified in 16.4% (n=132) by the referring radiologist with equivocal findings in 5.9% (n=48). The IOA of the different clinical centers varied between 63.2% (n=38, CI 0.48-0.78) and 92.3% (n=65, CI 0.86-0.99). The IOA for the diagnosis of infiltrates was significantly higher for inpatients with 82.6% (n=546; CI 0.80-0.85) than for outpatients with 55.2 % (n=80; CI 0.47-0.63), p<0.0001. The IOA of infiltrates with a transparency >50% was 95.1% (n=215; CI 0.92-0.98) versus 80.4% (n=403; CI 0.77-0.84) for infiltrates with a transparency >50% (p<0.0001). In patients with positive auscultation, the IOA was higher (p=0,034). Chest x-rays of patients with antibiotic therapy or an alveolar infiltrate showed more equivocal findings compared to patients without these features. CONCLUSION There is considerable interobserver variability in the diagnosis of pulmonary infiltrates on chest radiographs. The IOA is higher in more opaque infiltrates, positive auscultation and inpatients.
Consensus Analysis of Second-Order Multi-Agent Networks With Sampled Data and Packet Losses

In this paper, we address the consensus problem of second-order multi-agent system with sampled-data and packet losses. A Bernoulli stochastic variable is used to characterize the random packet losses in second-order multi-agent system with sampled-data information, in which packet losses are modeled in a successive way. Based on the matrix exponential and stochastic analysis techniques, several sufficient conditions are given to ensure the almost surely synchronization of second-order multi-agent networks with sampled-data and packet losses, where the graph among the agents is a directed network containing a directed spanning tree. Additionally, we further investigate the almost surely consensus for such system containing time-delays and packed dropouts. On this occasion, the communication graph among the agents is represented by an undirected connected graph. Furthermore, it is found that the probability of packet losses and the modulus of eigenvalues of the Laplace matrix play a vital role in achieving almost surely consensus. In the end, the developed results are applied to the coordination of multiple vehicles. Two examples are provided to illustrate the effectiveness of our results.
Electronic structure of GaxAl1-xSb alloys by empirical pseudopotential method

Electronic band structure calculations are reported for the Ga<sub>x</sub>Al<sub>1-x</sub>Sb alloys using empirical pseudopotential method within the virtual crystal approximation. The calculations show that the system of Ga<sub>x</sub>Al<sub>1-x</sub>Sb alloys consists of multiple valley conduction bands. The Gamma-L crossover is found for the Ga<sub>0.74</sub>Al<sub>0.26</sub>Sb alloy well in agreement with the experimental findings. The conduction band minimum (CBM) has been observed to switch at the (0.87,0,0) point for Ga<sub>0.51</sub>Al<sub>0.49</sub>Sb. The CBM shifts to the X point for Ga<sub>0.21</sub>Al<sub>0.79</sub>Sb alloy and remains at X leading Anally to indirect band gap in AlSb. The calculations have been used to report bowing parameters E<sub>X</sub> and E<sub>L</sub> for the alloys. Our findings may be useful to select the materials in a range of composition to examine the bowing parameter E<sub>X</sub> and effective mass experimentally to design low dimensional quantum systems. Refractive indices for all the alloys are also calculated for possible comparison with experiments to appear in future.
Variability and constraint in the mammalian vertebral column

Patterns of vertebral variation across mammals have seldom been quantified, making it difficult to test hypotheses of covariation within the axial skeleton and mechanisms behind the high level of vertebral conservatism among mammals. We examined variation in vertebral counts within 42 species of mammals, representing monotremes, marsupials and major clades of placentals. These data show that xenarthrans and afrotherians have, on average, a high proportion of individuals with meristic deviations from species’ median series counts. Monotremes, xenarthrans, afrotherians and primates show relatively high variation in thoracolumbar vertebral count. Among the clades sampled in our dataset, rodents are the least variable, with several species not showing any deviations from median vertebral counts, or vertebral anomalies such as asymmetric ribs or transitional vertebrae. Most mammals show significant correlations between sacral position and length of the rib cage; only a few show a correlation between sacral position and number of sternebrae. The former result is consistent with the hypothesis that adult axial skeletal structures patterned by distinct mesodermal tissues are modular and covary; the latter is not. Variable levels of correlation among these structures may indicate that the boundaries of prim/abaxial mesodermal precursors of the axial skeleton are not uniform across species. We do not find evidence for a higher frequency of vertebral anomalies in our sample of embryos or neonates than in post‐natal individuals of any species, contrary to the hypothesis that stabilizing selection plays a major role in vertebral patterning.
Serotonin syndrome in HIV-infected individuals receiving antiretroviral therapy and fluoxetine

ObjectiveTo describe HIV-infected individuals taking antidepressants who developed the serotonin syndrome due to drug–drug or drug–food interactions. Design and settingCase studies carried out at the HIV Outpatient Clinic, Atlanta Veterans Affairs Medical Center. Participants and interventionsHIV-positive patients who were receiving antiretroviral and antidepressant therapies and presented with symptoms consistent with the serotonin syndrome. Their antidepressants were discontinued or the doses reduced in order to resolve the symptoms. ResultsFive cases of serotonin syndrome developed after patients who were taking antidepressants ingested P450 inhibitors. ConclusionsSerotonin syndrome should be suspected in patients on serotonergic medications who present with mental status change, autonomic dysfunction, and neuromuscular abnormalities. Suspicion should be heightened in those who are ingesting substances known to inhibit P450 enzymes, such as protease inhibitors, non-nucleoside reverse transcriptase inhibitors, and grapefruit juice.

Design and Analysis of an Energy-Efficient CSMA Protocol for Asynchronous Multiple-Packet Reception

This paper proposes a carrier-sensing multiple access protocol for asynchronous multiple-packet reception (MPR), which enables wireless receivers to correctly decode partially time-overlapping packets. Unlike previous studies, which require back-off nodes to constantly monitor the channel, our design requires only that each node sense the number of transmitting nodes after the completion of the back-off period for determining whether to begin transmission in the next time slot. In addition, we develop an analytical model to evaluate relevant parameters and performance metrics of the proposed protocol. Our model relies on the channel-sensing probability of a node in a randomly chosen slot, rather than channel-accessing probability adopted in previous models for asynchronous MPR. The results are validated through numerical study under a variety of network conditions. We also show that the proposed protocol is quite robust to imperfect estimation in channel sensing, and is more energy-efficient than other similar threshold-based protocols.
Regulation of trophoblast invasion by IL-1beta and TGF-beta1.

PROBLEM To investigate the effect of IL-1beta and TGF-beta1 on trophoblast derived proteases and their inhibitors at the mRNA and protein level for elucidation of the mechanism of trophoblast invasion. METHOD OF STUDY Trophoblast derived proteases and their inhibitors were localized in human placental villi by immunohistochemistry, their regulation at mRNA and protein levels were studied using RT-PCR and zymography, respectively, on trophoblast cells in culture. RESULTS Trophoblast proteases, matrix metalloproteases (MMP-2, MMP-9), membrane type matrix metalloproteases (MT-MMP1 & 2) and urokinase type plasminogen activator (uPA) were found to be up regulated by IL-1beta while the protease inhibitors, tissue inhibitor of metalloproteases (TIMP-1 & 2) and plasminogen activator inhibitors (PAI-1 & 2) to be up regulated by TGF-beta1. CONCLUSION Temporo-spatial regulation of trophoblast invasion is the outcome of a balanced interplay between the proteases and their cognate inhibitors. IL-1beta and TGF-beta1 seem to be critical for regulating the protease network thereby effectively controlling the extent to which the trophoblast may invade the maternal endometrium.
Interaction of Mobile Telephone Radiation with Biological Systems in Veterinary and Medicine

Every day, we’re swimming in a sea of electromagnetic radiation produced by electrical appliances, power lines, wiring in buildings, and a group of other technologies that are part of modern life. Cell phones have become a vital part of our lives, and its use is not only restricted to voice conversations but also conveying news, high resolution pictures and internet. During recent years there has been increasing public concern on potential health risks from extremely low frequency electromagnetic ﬁelds and radiofrequency/microwave radiation emissions. It is fairly well established that at sufficiently high power levels, radiofrequency and microwave energy can produce deleterious biological effects. Some investigations suggested that these fields may have genotoxic effects and may increase the risk of several cancers and neurological disorders such as Alzheimer's disease. The aim of this review was to evaluate the influence of mobile telephone radiation on biological systems and health. It is concluded that these fields can influence several biological functions of cells and tissues, modulating intracellular reactive oxygen species levels and the cell cycle progression.

Objectives. To characterize the changes in the level of T helper 1 (Th1)‐ [interleukin (IL)‐2 and tumor necrosis factor (TNF)‐α] and Th2‐type cytokine (IL‐10) and the ratios of Th1/Th2 (IL‐2/IL‐10 and TNF‐α/IL‐10) in placentae from women with preeclampsia and women with gestational hypertension.
The need for new therapeutic approaches in visceral leishmaniasis during HIV infection.

Spontaneous sleep for 30 minutes during standard electroencephalography was attended by frequent snores; no apnoeic spells occurred. After 10 weeks of thyroid supplement, the facial appearance resembled that in a photograph taken 18 months earlier and the tongue had shrunk to average dimensions. Snoring continued for a further 1 month, ceasing abruptly 10 days after thyroxine had been increased from 50 to 75 ltg daily. Neurological symptoms and signs disappeared pari passu,3 none being present 4 months post-treatment. Radiography showed that the post-nasal space now had a typical configuration. Snoring signifies incomplete obstruction of the upper airway. ' Factors predisposing to a critical closing pressure during sleep include altered ventilatory control, a small oropharyngeal lumen and an increase in pharyngeal compliance.4 Each of these circumstances attends the hypothyroid state. While the tongue and pharynx are both sites where mucinous oedema is apt to occur,3'5' genioglossus enlargement has particular significance as this muscle is the key element opposing physiological pharyngeal closure. Its contractile properties, moreover, are deranged as well.5 Decreased sensitivity of respiratory neurones both to hypoxia and to hypercapnoea has been amply demonstrated in hypothyroidism.7-9 Hypotheses include a reset chemostat secondary to chronic alveolar hypoventilation8 and central effects of reduced body temperature and metabolic rate.6'9 Apnoea is the counterpart to snoring when upper airway obstruction becomes complete. Episodes of obstructive sleep apnoea (OSA) are common in untreated hypothyroidism and, furthermore, moderate with thyroid supplement. '0 Analogous mechananisms may be invoked when seeking to explain cessation of snoring in the present case. A reduction in body weight can be readily dismissed, since improvement of OSA has been observed in its absence.610 Besides, our patient was not obese. Concomitant resolution of myxoedema5 has obvious attractions. However, in at least 2 patients with OSA whose apnoeic episodes significantly decreased when euthyroid, the upper airway and neck pre-treatment were reputedly normal.6'1 Furthermore, in the present case snoring persisted beyond the time physical stigmata of myxoedema had disappeared. Normalizing of respiratory control6'10 may therefore be specially relevant. The manner in which thyroid hormone influences neural regulatory drive is unclear. Interestingly, elimination of OSA in a patient with hypothyroidism was effected not only by thyroxine but also by medroxyprogesterone which augments inspiratory effort independently of changes in chemical stimuli, metabolic rate or body temperature.6 Mechanisms aside, snoring is a predictable complication of hypothyroidism and thyroid function should be routinely evaluated in all habitual snorers.
The bilingual effect on Boston Naming Test performance

The present study aimed to determine how older bilingual subjects' naming performance is affected by their knowledge of two languages. Twenty-nine aging (mean age = 74.0; SD = 7.1) Spanish–English bilinguals were asked to name all pictures in the Boston Naming Test (BNT) first in their dominant language and then in their less-dominant language. Bilinguals with similar naming scores in each language, or relatively balanced bilinguals, named more pictures correctly when credited for producing a correct name in either language. Balanced bilinguals also named fewer pictures in their dominant language than unbalanced bilinguals, and named more pictures correctly in both languages if the pictures had cognate names (e.g., dart is dardo in Spanish). Unbalanced bilinguals did not benefit from the alternative (either-language) scoring procedure and showed cognate effects only in their nondominant language. These findings may help to guide the interpretation of neuropsychological data for the purpose of determining cognitive status in older bilinguals and can be used to develop models of bilingual language processing. Bilinguals' ability to name pictures reflects their experience with word forms in both languages. (JINS, 2007, 13, 197–208.)
The Influence of Socio-Economic Backgrounds towards Satisfaction with Student Housing Facilities

— Studies on residential satisfaction have been actively discussed under family house setting. However, limited studies have been conducted on student residential satisfaction. This study is an attempt to fill the research gap. It focuses on the influence of socioeconomic on students’ satisfaction with the universities’ student housing facilities. The students who stayed at the on-campus student housing were the respondents. This study employed two-stage cluster sampling method in classifying the respondents. Self-administered questionnaires were distributed face-to-face to the students. In general, it is confirmed that students’ socio-economic backgrounds have influence on the students’ satisfaction with their housing facilities. The main influential factors were the students’ economic status, sense of sharing, and ethnicity of their roommates. Furthermore, this study could also provide a useful feedback for the universities in order to improve their student housing facilities.
