Introduction Obsessive-Compulsive Disorder (OCD) is an anxiety disorder with a prevalence rate of 2% to 3% of the adult population. The clinical manifestations include persistent, intrusive thought and rituals or compulsions. To date, data from different lines of studies including neuronanatomical, neurosurgical, neuroparmacological and neruoimaging has provided important evidence implicating t...

The literature states that project duration is affected by various scope factors. Using 168 building projects carried out in Spain, this paper uses the multiple regression analysis to develop a forecast model that allows estimating project duration of new builds. The proposed model uses project type, gross floor area (GFA), the cost/GFA relationship and number of floors as predictor variables. ...

Ni57Zr22X8Nb8Al5 (X = Ti, Cu) metallic glass (MG) and nanocomposite powders were synthesized by mechanical alloying. Outstanding differences in glass-forming ability (GFA), thermal property, particle size and crystallization behavior were found for the two synthesized alloy powders with different alloying substitutions. The Ti-containing MG powder exhibits better GFA, higher thermal stability, ...

When a liquid is cooled well below its melting temperature at a rate that exceeds the critical cooling rate Rc, the crystalline state is bypassed and a metastable, amorphous glassy state forms instead. Rc (or the corresponding critical casting thickness dc) characterizes the glass-forming ability (GFA) of each material. While silica is an excellent glass-former with small Rc < 10(-2) K/s, pure ...

The U.S. National Cancer Institute (NCI) conducts a drug discovery program in which approximately 10,000 compounds are screened every year in vitro against a panel of 60 human cancer cell lines from different organs of origin. Since 1990, approximately 63,000 compounds have been tested, and their patterns of activity profiled. Recently, we analyzed the antitumor activity patterns of 112 ellipti...

The capacity of certain adeno-associated virus (AAV) vectors to cross the blood-brain barrier after intravenous delivery offers a unique opportunity for noninvasive brain delivery. However, without a well-tailored system, the use of a peripheral route injection may lead to undesirable transgene expression in nontarget cells or organs. To refine this approach, the present study characterizes the...

The likelihood that an undercooled liquid vitrifies or crystallizes depends on the cooling rate R. The critical cooling rate R(c), below which the liquid crystallizes upon cooling, characterizes the glass-forming ability (GFA) of the system. While pure metals are typically poor glass formers with R(c)>10(12)K/s, specific multi-component alloys can form bulk metallic glasses (BMGs) even at cooli...

BACKGROUND Giant fibroadenoma (GFA) has been defined as fibroadenoma greater than 5 cm in it's the widest diameter and/or weighing more than 500 g. A benign lesion, its size also raises the possibility of malignancy requiring differentiation from a malignant breast disease. When unilateral GFA presents with a severe breast asymmetry, due to its size, it is not correctable by simple enucleation ...

We tested the hypothesis that aging decreases endothelium-dependent vasodilation in feed arteries perfusing rat skeletal muscle. In addition, we tested the hypothesis that attenuated vasodilator responses are associated with decreased endothelial nitric oxide synthase (eNOS) and superoxide dismutase-1 (SOD-1) expression. Soleus feed arteries (SFA) and gastrocnemius feed arteries (GFA) were isol...

Grammar Flow Analysis (GFA) is a computation framework that can be applied to a large number of problems expressed on context-free grammars. In this framework, as was done on programs with Data Flow Analysis, those problems are split into a general resolution procedure and a set of speciic propagation functions. This paper presents a number of improvement techniques that act on the resolution p...
