Inhibitor-resistant TEM (IRT) type β-lactamase mutation is largely known. Therefore, it is of interest to identify new yet improved leads against IRT from traditional Chinese medicine. Hence, we screened more than 10,000 compounds from Chinese medicine (tcm@taiwan database) with mutant molecular IRT models through docking techniques. This exercise identified compounds affeic acid, curcumin, sal...

Researchers commonly apply item response theory (IRT) models to binary and ordinal items in order to measure an underlying trait using a collection of observed responses to test questions or items. For binary items, a common IRT model is the two parameter logistic (2PL) form. Assume that we have observed p item responses for n individuals where a correct responses is designated with a ’1’ and a...

Item response theory (IRT) is a modern test theory that has been used in various aspects of educational and psychological measurement. The fully Bayesian approach shows promise for estimating IRT models. Given that it is computationally expensive, the procedure is limited in real applications. It is hence important to seek ways to reduce the execution time, and therefore, a suitable solution is...

Dalam upaya meningkatkan kualitas dan daya saing produk UMKM, pemerintah Indonesia menerapkan serta mengembangkan beberapa standar sertifikasi yang harus dilengkapi oleh pelaku usaha. Salah satunya adalah Sertifikat Produksi Pangan Industri Rumah Tangga (SPP-IRT). Sertifikasi ini merupakan cara untuk kesadaran UMKM dalam Cara Pengolahan Baik (CPPB-IRT). Penduduk mayoritas muslim, sehingga konsu...

The design features of the research reactor IRT-2000 in Sofia and accumulated experience in the past prior to the partial dismantling of obsolete reactor systems are outlined. The present status of the ongoing refurbishment to a low power reactor IRT-200 and its planned utilization are briefly described.

The objectives of this experiment were to determine interrelationships among mastitis indicators and evaluate the subclinical mastitis detection ability of infrared thermography (IRT) in comparison with the California Mastitis Test (CMT). Somatic cell count (SCC), CMT, and udder skin surface temperature (USST) data were compiled from 62 Brown Swiss dairy cows (days in milk=117+/-51, milk yield=...

BACKGROUND Although biostatistics and clinical epidemiology are essential for comprehending medical evidence, research has shown consistently low and variable knowledge among postgraduate medical trainees. Simultaneously, there has been an increase in the complexity of statistical methods among top-tier medical journals. AIMS To develop the Biostatics and Clinical Epidemiology Skills (BACES) ...

The Swedish driving-license test consists of a theory test and a practical road test. The aim of this paper is to evaluate which Item Response Theory (IRT) model among the one (1PL), two (2PL) and three (3PL) parameter logistic IRT models that is the most suitable to use when evaluating the theory test in the Swedish driving-license test. Further, to compare the chosen IRT model with the indice...

Item response theory (IRT) was used to investigate whether this method could be applied to measure HRD effectiveness. Attention was given to handling missing data, interpretation of IRT-scores, and comparison with a comprehensive model for explaining HRD effectiveness. An acceptable fit was shown. The IRT method provided much information about the performance of HRD programs with respect to com...

Organisation s value chains are part of a wider chain of events – value networks. This paper explores the role of Internet-related technologies (IRT) in improving inter-organisational linkages and information sharing across value networks and the impact it has on the level of product or service delivered to customers. Using case study findings, the paper illustrates how IRT have strengthened an...
