A 2 X = C 2 , respectively. As applications, we present necessary and sufficient condition for the previous matrix function f(X, Y) to be positive (negative), non-negative (positive) definite or nonsingular. We also characterize the relations between the Hermitian part of the solutions of the above-mentioned matrix equations. Furthermore, we establish necessary and sufficient conditions for the...

This work was supported by the Global Emerging Infections and Surveillance System, a Division of the Armed Forces Health Surveillance Center and in part by the National Institutes of Health under KL2 RR024994. The study protocol DOD NAMRU3.2000.0002 (IRB Protocol No. 096) was hospital-based surveillance for enteric pathogens asso...

pursuant to the provisions of the Economic Opportunity Act of 1964. The author is grateful to David L. Featherman for helpful comments on an earlier draft and to Arthur S. Goldberger for helpful discussions at several stages, but neither colleague necessarily agrees with any part of the current version. ABSTRACT The book under review deals with modelS which identify and measure factors determin...

Firestone et al., 2007, PNAS 104(41): 16,016–16,021, proposed that a major cosmic impact, circa 10,835 cal. BCE, triggered the Younger Dryas (YD) climate shift along with changes in human cultures and megafaunal extinctions. Fourteen years after this initial work overwhelming consensus of research undertaken by many independent groups, reviewed here, suggests their claims impact at time should ...

Israde-Alcántara et al. (1) drew on interpretations of a core from Lake Cuitzeo, Mexico to support the Younger Dryas (YD) Impact Hypothesis. A key aspect of their study was identifying and dating the YD interval in the sediments. The authors stated that they recovered impact indicators from a 10-cm-thick zone dating to 12.9 kcal BP but provided no direct numerical age control or chronological u...

Abstract Introduction Female sexual dysfunction includes many different conditions that involve desire, arousal, orgasm, and pain. More than 40% of American women report problems nearly 12% meet the criteria for a diagnosed dysfunction. Given sensitivity topic, turn to Internet find information. In specific, social media allows users interact with others by creating, viewing commenting on conte...

A series of extensional structures, including the southern Tibet detachment system (STDS), north-south trending rifts (NSTR), and northern Himalayan gneiss dome (NHGD), developed from collision compression between Indian Eurasian plates. These tectonic movements were accompanied by magmatism polymetallic mineralization. Cuona Rift (CR) is located on STDS next to Yalaxiangbo Dome (YD) passes thr...
