A neural network based coherent detector is proposed for detecting gaussian targets in gaussian clutter. Target and clutter ACF are supposed gaussian with different powers and one lag correlation coefficients. While clutter mean Doppler frequency is set to 1, the influence of target mean Doppler frequency is considered. The neural detector performance is compared to the Neyman-Pearson one. For ...

Background. Protein dihedral angles provide a detailed description of protein local conformation. Predicted dihedral angles can be used to narrow down the conformational space of the whole polypeptide chain significantly, thus aiding protein tertiary structure prediction. However, direct angle prediction from sequence alone is challenging. Method. In this study, we present a novel method to pre...

A Collaborative Filtering was successfully implemented using the computer programming language Java to produce recommendations between users such that only similar users were considered. Both Mean Squared Difference (MSD) and Pearson Correlation Coefficient (PCC) were used and evaluations carried out on each. The metric which performed best on the u.data file was PCC with L = 0. Conversely, the...

An efficient strategy for reducing message transmission in a wireless sensor network (WSN) is to group sensors by means of an abstraction denoted cluster. The key idea behind the cluster formation process is to identify a set of sensors whose sensed values present some data correlation. Nowadays, sensors are able to simultaneously sense multiple different physical phenomena, yielding in this wa...

The aim of this study was to screen for key biomarkers of osteosarcoma (OS) by tracking altered modules. Protein-protein interaction (PPI) networks of OS and normal groups were constructed and re-weighted using the Pearson correlation coefficient (PCC), respectively. The condition-specific modules were explored from OS and normal PPI networks using a clique-merging algorithm. Altered modules we...

BACKGROUND Assessment of treatment response by measuring tumor size is known to be a late and potentially confounded response index. Serial diffusion MRI has shown potential for allowing earlier and possibly more reliable response assessment in adult patients, with limited experience in clinical settings and in pediatric brain cancer. We present a retrospective study of clinical MRI data in chi...

Methods Retrospective analysis of 30-days mortality in 62 pts (49 male,13 female, mean age 65,74 ± 11,18) hospitalized in our ICU. Age, Apache II score, Sofa score and GCS were recorded on admission day. CT-scan was performed in order to determine the site of the ICH, the presence of intraventricular hemorrhage (IVH) and the amount of ICH. Volume was estimated using the ABC/2 method and the big...

Objectives and Methods. Several researchers have provided support for the critical role of cognitive vulnerabilities in the development of depression. The Attitudes toward Self-Revised (ATS-R) was designed to assess three potential self-regulatory vulnerabilities to depression: High Standards (HS), Self-Criticism (SC), and Negative Generalization (NG). The aim of the study was to assess the psy...
