To cope with the continuously incoming stream of input, the visual system has to group information across space and time. Usually, spatial and temporal grouping are investigated separately. However, recent findings revealed that these two grouping mechanisms strongly interact and should therefore be studied together rather than in isolation. Here, we show that spatio-temporal grouping is very s...

(ODI) – for discussions at an early stage of this paper. Parts of the paper also draw on work undertaken by the Political Economy of Agricultural Policy in Africa (PEAPA) project within the Future Agricultures Consortium (www.future-agricultures.org/peapa). Ultimately, however, the interpretation in the paper is mine, as are all errors and omissions.

INTRODUCTION Efforts to address health disparities and achieve health equity are critically dependent on the development of a diverse research workforce. However, many researchers from underrepresented backgrounds face challenges in advancing their careers, securing independent funding, and finding the mentorship needed to expand their research. METHODS Faculty from the University of Maryland...

BACKGROUND On June 11, 2009, the World Health Organization declared phase 6 of the novel influenza A/H1N1 pandemic. Although by the end of September 2009, the novel virus had been reported from all continents, the impact in most countries of the northern hemisphere has been limited. The return of the virus in a second wave would encounter populations that are still nonimmune and not vaccinated ...

Rangachari PK. Teaching undergraduates the process of peer review: learning by doing. Adv Physiol Educ 34: 137–144, 2010; doi:10.1152/advan.00071.2009.—An active approach allowed undergraduates in Health Sciences to learn the dynamics of peer review at first hand. A four-stage process was used. In stage 1, students formed self-selected groups to explore specific issues. In stage 2, each group p...

a new multi-stage fuzzy (msf) controller based on multi-objective harmony search algorithm (mohsa) is proposed in this paper to solve the load frequency control (lfc) problem of power systems in deregulated environment. lfc problem are caused by load perturbations, which continuously disturb the normal operation of power system. the objectives of lfc are to mini small size the transient deviati...

the predator-prey model with stage structure for predator is generalized in the context of ecoepidemiology, where the prey population is infected by a microparasite and the predator completely avoids consuming the infected prey. the intraspecific competition of infected prey is considered. all the equilibria are characterized and the existence of a hopf bifurcation at the coexistence equilibriu...

the development of optimization and mathematical models for closed loop supply chain (clsc) design has attracted considerable interest over the past decades. however, the uncertainties that are inherent in the network design and the complex interactions among various uncertain parameters are challenging the capabilities of the developed tools. the aim of this paper, therefore, is to propose a n...

background the invention of central venous catheters (cvc) for hemodialysis (hd), brought about a fundamental change in the treatment of patients who needed hd, from the late 1970’s till the present time. nowadays the use of cvc is a common medical procedure. increasing use of these methods necessitates clarification of the exact nature of the effects, and potential complications for surgeons. ...

conclusions the administration of curcumin in patients undergoing dialysis had no positive effects on enhancing lvef and lv function. further research is required to shed sufficient light on this issue. results the mean age was 44.2 ± 13.4 years for the curcumin group and 45.4 ± 6.2 years for the placebo group. the study population comprised 22 male and 13 female patients. there were no signifi...
