60 GHz millimeter-wave networks represent the next frontier in high-speed wireless access technologies. Due to the use of highly directional and electronically steerable beams, the performance of 60 GHz networks becomes a sensitive function of environment structure and reflectivity, which cannot be handled by existing networking paradigms. In this paper, we propose E-Mi, a framework that harnes...

BACKGROUND The spiro- indole-pyrrolidine ring system is a frequently encountered structural motif in many biologically important and pharmacologically relevant alkaloids. The derivatives of spirooxindole ring systems are used as antimicrobial, antitumour agents and as inhibitors of the human NKI receptor besides being found in a number of alkaloids like horsifiline, spirotryprostatin and (+) el...

Thcrc is good evidence that pyruvate and lactate are important sources of cncrgy for the intact heart. Early studies by Himwich cl al. (1) in the> open chest dog and by McGinty and Miller (2) in the heart-lung preparation showed that lactate was removed from the coronary blood during its perfusion of the myocardium. Subsequent studies by Braun-Menendez et al. (3) with the isolated circulating h...

Bipolar disorder and severe premenstrual syndrome (PMS) have many symptoms in common, but it is important to establish the correct diagnosis between a severe psychiatric disorder and an endocrine disorder appropriately treatable with hormones. The measurement of hormone levels is not helpful in making this distinction, as they are all premenopausal women with normal follicle-stimulating hormone...

Amiodarone is a viable drug for preventing sudden cardiac death, particularly during the first year after MI. If larger trials confirm the aforementioned prospective trials of Ceremuzynski et al, Cairns et al, and the BASIS trial, the efficacy of amiodarone would outweigh the risk of its side effects during the first year after MI. Based on the long-term observation from the BASIS trial, the du...
