The allocation of deceased donor kidneys has become more complex because of the increasing spectrum of donors and recipients age and comorbidities. Several scoring systems have been proposed to evaluate the donor quality of deceased donor kidneys, based on clinical, pathological or combined parameters to predict the risk of renal allograft failure. Nonetheless, besides the dichotomous extended ...

Model-based clinical trial designs have drawn much attention from the biostatistical community since 1990 when O’Quigley et al. proposed the Continual Reassessment Method (CRM). CRM and its various modified versions have achieved great successes in finding the maximum tolerated dose (MTD) adaptively in the case of dichotomous toxicity responses (i.e. dose-limiting toxicity, DLT, or non-DLT). In...

This paper compares, for a microfinance institution, the performance of two individual classification models: Logistic Regression (Logit) and Multi-Layer Perceptron Neural Network (MLP), to evaluate the credit risk problem and discriminate good creditors from bad ones. Credit scoring systems are currently in common use by numerous financial institutions worldwide. However, credit scoring using ...

Sequence alignment is a central problem in bioinformatics. The classical dynamic programming algorithm aligns two sequences by optimizing over possible insertions, deletions and substitution. However, other evolutionary events can be observed, such as inversions, tandem duplications or moves (transpositions). It has been established that the extension of the problem to move operations is NP-com...

Dichotomous keys are the most popular type of identification keys. Studies have been conducted to evaluate dichotomous keys in many aspects. In this paper we propose an index for quantitative evaluation of dichotomous keys (Edicho). The index is based on the evenness and allows comparing identification keys of different sizes.

Description of a new species from Australia, belonging to the subgenus Selenkothuria (Holothuria, Aspidochirotida). A dichotomous key of the thirteen valid species included in the subgenus is also given. The species H. perrieri Thandar, 1977 and H. spinea Cherbonnier, 1988 are considered as non valid.

this study aimed at investigating the reliability, predictive validity, and self-esteem and gender bias of confidence-based scoring. this is a method of scoring in which the test takers receive a positive or negative point based on their rating of their confidence in an answer. the participants, who were 49 english-major students taking their grammar course, were given 8 multiple-choice tests d...
