Given a positive integer n and a graph F , the Turán number ex(n, F ) is the maximum number of edges in an n-vertex simple graph that does not contain F as a subgraph. Let H be a graph and p a positive even integer. Let H(p) denote the graph obtained from H by subdividing each of its edges p−1 times. We prove that ex(n,H(p)) = O(n1+(16/p)). This follows from a more general result that we establ...

BACKGROUND Evidence suggests that elevated systolic blood pressure (SBP) and pulse pressure (PP) in midlife is associated with increased risk for cognitive impairment later in life. There is mixed evidence regarding the effects of late life elevated SBP or PP on cognitive function, and limited information on the role of female gender. METHODS/PRINCIPAL FINDINGS Effects of SBPand PPon cognitiv...

OBJECTIVE The Action to Control Cardiovascular Risk in Diabetes lipid study (ACCORD Lipid), which compared the effects of simvastatin plus fenofibrate (FENO-S) versus simvastatin plus placebo (PL-S) on cardiovascular disease outcomes, measured only fasting triglyceride (TG) levels. We examined the effects of FENO-S on postprandial (PP) lipid and lipoprotein levels in a subgroup of ACCORD Lipid ...

Unlike other animals that live outside the tropics, humans are susceptible to peripheral cold injuries. The highest homeostatic priority is to maintain the body’s core temperature. This is accomplished through peripheral vasoconstriction and shunting, which prevent adequate heat distribution to the extremities. As a result, failure to achieve adequate protection from the environment results in ...

The particle-particle random phase approximation (pp-RPA) has been used to investigate excitation problems in our recent paper [Y. Yang, H. van Aggelen, and W. Yang, J. Chem. Phys. 139, 224105 (2013)]. It has been shown to be capable of describing double, Rydberg, and charge transfer excitations, which are challenging for conventional time-dependent density functional theory (TDDFT). However, i...

BACKGROUND Current definitions of hypertension are based on levels of systolic blood pressure (SBP) and diastolic blood pressure (DBP), but not on pulse pressure (PP). We examined whether PP adds useful information for predicting coronary heart disease (CHD) in the population-based Framingham Heart Study. METHODS AND RESULTS We studied 1924 men and women between 50 and 79 years of age at base...

To assess whether there is a role for ambulatory blood pressure monitoring (ABPM) in screening for hypertension, we conducted Bayesian analysis of office blood pressure (OBP) as a diagnostic "test" in populations with different prior probabilities (PP) of hypertension. OBP was considered a positive test if systolic blood pressure was greater than 140 mm Hg or diastolic pressure was greater than...
