Serotonin is implicated in many aspects of behavioral regulation. Theoretical attempts to unify the multiple roles assigned to serotonin proposed that it regulates the impact of costs, such as delay or punishment, on action selection. Here, we show that serotonin also regulates other types of action costs such as effort. We compared behavioral performance in 58 healthy humans treated during 8 w...

The Sequence Ontology (SO) is a structured, controlled vocabulary that provides terms and definitions for genomic annotation. Gene Regulation Ensemble Effort the Knowledge Commons (GREEKC) initiative has gathered input from many groups of researchers, including SO, (GO), gene regulation experts, with goal curating information about how expression regulated at molecular level. Here we discuss re...

This paper discusses an approach of QoS service differentiation in mobile ad hoc networks. We aim to investigate the performances of the proposed semi-stateless approach, named “MARS”, over the existing stateless approaches. Mars supports both real-time UDP traffic, and best-effort UDP and TCP traffic. The main objective of MARS is to minimize the end-to-end delay of traffic. The proposed model...

Online bandwidth limitations and fluctuations impose a major challenge in estimating the amount of data to transmit in a given time period. Over or under estimation of bandwidth can jeopardize the visual fidelity of the transmitted data and related multimedia data. We propose a Visual Quality Prediction (VQP) model which supports an adaptive fragmented texture transmission approach taking bandw...

When developing and aiming to achieve success in the arena of mobile commerce, user acceptance is a key aspect for consideration. This study aims to empirically examine some of the factors affecting the acceptance of m-commerce within the context of Saudi Arabia. Based on the revised UTAUT model, the revised model include two particular construct : costs and trust to enhance our understanding o...

The present study tested and extended Lane and Terry (2000) conceptual model of mood-performance relationships using a large dataset from an online experiment. Methodological and theoretical advances included testing a more balanced model of pleasant and unpleasant emotions, and evaluating relationships among emotion regulation traits, states and beliefs, psychological skills use, perceptions o...
