background: for an effective treatment planning in brachytherapy, it is necessary to know the accurate source dosimetric information such as air kerma strength, exposure rate constant, dose rate constant and redial dose distribution. the usual method to determine these factors is thermo luminescent dosimeter (tld) dosimetry. nowadays, another more accurate method is known to be the monte carlo ...

Artificial Bandwidth Extension (ABE) has been introduced to improve perceived speech quality and intelligibility of narrowband telephone speech. Most of the existing algorithms divided ABE into 2 sub-problems, namely extension of the excitation signal and that of the spectral envelope. In this paper, we propose a new method for spectral envelope extension based on REgularized piecewise linear m...

Strategies for drug discovery and repositioning are urgently need with respect to COVID-19. Here we present REDIAL-2020, a suite of computational models estimating small molecule activities in range SARS-CoV-2-related assays. Models were trained using publicly available, high-throughput screening data by employing different descriptor types various machine learning strategies. describe the deve...

Call-blocking probabilities are among the key performance measures in mobile communications networks. For the analysis of these blocking probabilities, mobile networks can be modelled as networks of Erlang loss queues with common capacity restrictions dictated by the distribution of frequencies over the cells of the network. However, due to the time-varying load offered to the cells of such net...

In many call centers, callers may call multiple times. Some of the calls are reattempts after abandonments (redials), and some are re-attempts after connected calls (reconnects). The combination of redials and reconnects has not been considered when making staffing decisions, while ignoring them will inevitably lead to underor overestimation of call volumes, which results in improper and hence ...

In practice, in many call centers customers often perform redials (i.e., reattempt after an abandonment) and reconnects (i.e., reattempt after an answered call). In the literature, call center models usually do not cover these features, while real data analysis and simulation results show ignoring them inevitably leads to inaccurate estimation of the total inbound volume. Therefore, in this pap...

Two hundred Galba truncatula, originating from a French population, were subjected to single-miracidium infections with an allopatric isolate (origin, Argentina) of Fasciola hepatica. The control group was constituted by 100 snails coming from the same population and exposed to sympatric miracidia of F. hepatica according to the same protocol. Snail samples were collected bimonthly from both gr...
