Selective sustained attention (SSA) is vital for higher order cognition. Although endogenous and exogenous factors influence SSA, assessment of the degree to which these factors influence performance and learning is often challenging. We report findings from the Track-It task, a paradigm that aims to assess the contribution of endogenous and exogenous factors to SSA within the same task. Behavi...

To identify sounds as novel, there must be some neural representation of commonly occurring sounds. Stimulus-specific adaptation (SSA) is a reduction in neural response to a repeated sound. Previous studies using an oddball stimulus paradigm have shown that SSA occurs at the cortex, but this study demonstrates that neurons in the inferior colliculus (IC) also show strong SSA using this paradigm...

The rising prevalence of cardiovascular disease in sub-Saharan Africa (SSA) constitutes a significant health and socio-economic challenge for the countries in the region. This study examines the patterns and scientific impact of international collaboration in cardiovascular research (CVR) in SSA. Bibliographic data from 2005 to 2014 were obtained from the Web of Science for cardiovascular-relat...

Somatostatin analogs (SSA) with their potent antisecretory and antiproliferative effects are the main medical treatment option for patients with neuroendocrine tumors, such as gastroenteropancreatic and acromegaly-associated growth hormone secreting pituitary tumors. Although a good portion of acromegalic patients gets normalized after SSA treatment, strict hormonal control is not achieved in a...

Array SSA form is a version of SSA form that captures precise element-level data flow information for array variables. As an example of program analysis using Array SSA form, we presented a conditional constant propagation algorithm that can lead to discovery of a larger set of constants than previous algorithms that analyze only scalar variables [7]. As an example of program transformation usi...

This report focuses on studying generation and/or evolution of sea-salt aerosols (SSA) on basis of measurements in the Northwest Pacific Ocean (NWPO), the marginal seas of China, at sea-beach sites and a semi-urban coastal site in 2012-2015. From measurements in the NWPO, we obtained the smallest generation function of the super-micron SSA mass ([MSSA]) by the local wind comparing to those prev...

The master equation of chemical reactions is solved by first approximating it by the Fokker–Planck equation. Then this equation is discretized in the state space and time by a finite volume method. The difference between the solution of the master equation and the discretized Fokker–Planck equation is analyzed. The solution of the Fokker–Planck equation is compared to the solution of the master...

The analysis of chaotic time series requires proper reconstruction of the state space from the available data in order to successfully estimate invariant properties of the embedded attractor. Using the correlation dimension, we discuss the applicability of the two most common methods of reconstruction, the method of delays (MOD) and the Singular Spectrum Approach (SSA). Contrary to previous dis...

INTRODUCTION There is a need for interventions to address the escalating mental health burden in Sub-Saharan Africa (SSA). Implementation of physical activity (PA) within the rehabilitation of people with mental health problems (PMHP) could reduce the burden and facilitate recovery. The objective of the current review was to explore (1) the role of PA within mental health policies of SSA countr...

This paper projects the future of knowledge economy (KE) in SSA and MENA countries using the four components of the World Bank’s Knowledge Economy Index (KEI): economic incentive, education, ICTs and innovation. The empirical evidence provides the speeds of integration as well as the time necessary to achieve full integration. Findings broadly indicate SSA and MENA countries with low levels in ...
