The pathophysiology of post-stroke fatigue is poorly understood although it is thought to be a consequence of central nervous system pathophysiology. In this study we investigate the relationship between corticomotor excitability and self-reported nonexercise related fatigue in chronic stroke population. Seventy first-time non-depressed stroke survivors (60.36 12.4 years, 20 females, 56.81 63 m...

likely than nonusers to engage in risky sexual behavior and that they are less likely than nonusers to rely on condoms. In some studies, condom use has been treated as one component of a sexual-risk index, which is then related to substance use. In other research, condom use has been treated as a separate independent variable, which is then related to substance use directly. In this article, we...

Why do some actors in international politics display remarkable persistence in wartime, while others “cut and run” at the first sign of trouble? I offer a behavioral theory of resolve, suggesting that variation in time and risk preferences can help explain why some actors display more resolve than others. I test the theory experimentally in the context of public opinion about military intervent...

Sorosphaera viticola is a soil-borne, endophytic parasite of grapevine. It is classifi ed within the plasmodiophorids, an enigmatic group of obligate biotrophic parasites of higher plants. Sorosphaera viticola has been found abundantly in the roots of Vitis spp. in Germany and Canada. This may indicate a global distribution of this root parasite. But its biphasic life-cycle, its soil-borne natu...

This paper shows the results of research on the optical control of a GaAs chip monolithic amplifier, and is an extension of previous work by our group in the field of optical-microwave interaction [1-3]. The amplifier was originally designed for the transmitter stage of an indoor mobile communications system in the 2.4 GHz band. The possibilities of optical control of this amplifier are evidenc...

OBJECTIVES To determine whether postoperative delirium predicts first-time readmissions and mortality in octogenarian patients within 180 days after aortic valve therapy with surgical aortic valve replacement (SAVR) or transcatheter aortic valve implantation (TAVI), and to determine the most common diagnoses at readmission. DESIGN Prospective cohort study of patients undergoing elective SAVR ...
