The study is focused on finding out the level of use of on-line databases by faculty members and research scholars of the Jawaharlal Nehru University (JNU) and Jamia Millia Islamia (JMI), Delhi (India). Both are Central Universities and are funded by the University Grants Commission (UGC). A well-structured questionnaire was administered to faculty members and research scholars of the JNU and JMI to collect data regarding the use of on-line database. The survey reveals that all of the faculty members and research scholars are aware of the availability of on-line databases and largely use them for reference purposes in their research work and studies. The degree of usefulness and utilization of on-line databases is high among the universities' faculty members and research scholars. The survey further reveals that the respondents from both universities are aware of the search options for accessing on-line databases. It is also found that a large number of respondents of JNU and JMI are using field searching and Boolean operators to access information from on-line databases. 相似文献

Introduction:
The aim of this study was to investigate whether serum levels of interleukin-1β (IL–1β) has any possible correlation on inflammatory parameters such as C-reactive protein (CRP), erythrocyte sedimentation rate (ESR) and fibrinogen concentration in patients with familial Mediterranean fever (FMF) patients during attack-free period.Materials and methods:
The serum levels of IL-1β, as an indicator of cytokines status, and the acute phase response proteins, CRP, ESR and fibrinogen levels were evaluated in 35 attack-free patients with FMF and 25 healthy volunteers.Results:
Serum IL-1β levels were significantly higher in patients with FMF than control subjects (P = 0.018). There was no statistically significant difference in the serum levels of ESR, CRP and fibrinogen between two groups (P = 0.181, P = 0.816, P = 0.686, respectively). There was a significant correlation between IL-1β and CRP (r = 0.513, P = 0.002) values of FMF group.Conclusions:
In conclusion, our results confirm the presence of increased IL-1β levels in FMF patients during attack-free period. Serum IL-1β values seems to correlate with CRP levels. The elevation of IL-1β levels may be important in monitoring subclinical inflammation of attack free period in FMF patients. 相似文献64.

This paper presents our work towards developing a new speech corpus for Modern Standard Arabic (MSA), which can be used for implementing and evaluating Arabic speaker-independent, large vocabulary, automatic, and continuous speech recognition systems. The speech corpus was recorded by 40 (20 male and 20 female) Arabic native speakers from 11 countries representing three major regions (Levant, Gulf, and Africa). Three development phases were conducted based on the size of training data, Gaussian mixture distributions, and tied states (senones). Based on our third development phase using 11 hours of training speech data, the acoustic model is composed of 16 Gaussian mixture distributions and the state distributions tied to 300 senones. Using three different data sets, the third development phase obtained 94.32% and 8.10% average word recognition correctness rate and average Word Error Rate (WER), respectively, for same speakers with different sentences (testing sentences). For different speakers with same sentences (training sentences), this work obtained 98.10% and 2.67% average word recognition correctness rate and average WER, respectively, whereas for different speakers with different sentences (testing sentences) this work obtained 93.73% and 8.75% average word recognition correctness rate and average WER, respectively. 相似文献

Intersymbol interference (ISI) degrades the bit error rate (BER) performance of sequential detectors such as maximum likelihood sequence detection (MLSD) and the maximum a posteriori (MAP) algorithm due to minimum distance reduction. This paper describes a novel rotation method that can increase the minimum distance and results in significant improvement in the BER performance for binary PSK and 4QAM systems when operating over severe ISI channels. Simulation results show that this method can improve the BER performance of systems employing MLSD and MAP turbo equalization by up to 4.6 dB compared to existing approaches including known precoding schemes. 相似文献

In basketball, the defender’s reaction to a pass is slower and more error prone if the attacking player gazes into the opposite direction. This so-called head-fake effect might be modulated by context information, that is, the frequency and the sequence of head fakes occurring. Accordingly, the present study investigates the head-fake effect for different frequency proportions (20% vs. 50% vs. 80%). The results show that the head-fake effect decreases when the head fake occurs more often. Furthermore, a potential influence of previous fake experience (i.e., congruency-sequence effect) on the size of the head-fake effect was investigated. Importantly, previous fake experience did not cause the frequency-based modulation of the general size of the head-fake effect. These findings bare important implications for sports practice, especially when it comes to instructing players about the tactical use of deceptive actions. 相似文献

In this paper, the numerical solution of differential-algebraic equations is considered by Padé approximation method. We applied this method to an example which is a physical model problem. Firstly the physical model problem has been converted to power series, then the numerical solution of physical model problem was put into Padé series form. Thus we obtained numerical solution of physical model problem. 相似文献

The degree to which pre-service teachers learn biology is related to both motivational factors of self-regulation and factors
regarding epistemological beliefs. At the same time, self-regulation and epistemological beliefs are also associated with
one another. Based on this relationship, the purpose of this study was to investigate the relationship between components
of epistemological beliefs and self-refulation (self-efficacy and test-anxiety) on learning biology. The study was conducted
with 411 pre-service elementary and pre-service elementary science teachers by using a predictive research approach. Collected
data was analyzed by the multiple linear regression technique. The results showed that only the belief about “existence of
one truth” was a significant predictor of test anxiety while there was no epistemological predictor of self-efficacy. Conclusions
and implications of the study will be discussed. 相似文献
