Background: In intensity modulated radiation therapy, cone beam computed tomography (CT) has been used to evaluate patients prior to treatment. This study conducted a comparative evaluation of the image reconstruction ability of the clinically used half-fan bowtie filter and the full-fan bowtie filter. Materals and Methods: A CT simulation marker was inserted inside a human phantom, and the pel...
The WD-40 repeat protein FAN binds to a distinct domain of the p55 receptor for tumor necrosis factor (TNF) and signals the activation of neutral sphingomyelinase (N-SMase). To analyze the physiological role of FAN in vivo, we generated FAN-deficient mice by targeted gene disruption. Mice lacking a functional FAN protein do not show any overt phenotypic abnormalities; in particular, the archite...
Excessive coupling between object-oriented classes is widely acknowledged as a maintenance problem that can result in a higher propensity for faults in systems and a ‘stored up’ future problem. This paper explores the relationship between ‘fan-in’ and ‘fan-out’ coupling metrics over multiple versions of opensource software. More specifically, the relationship between the two metrics is explored...
Generation of proapoptotic sphingolipids by neutral sphingomyelinase activation is an early response to hypoxia/reoxygenation (HR) in cardiomyocytes. Factor associated with neutral sphingomyelinase activation (FAN) mediates activation of sphingomyelinase and subsequent apoptosis. However, the participation of FAN in HR-induced cardiomyocyte cell death has not been elucidated. We therefore inves...
The Gröbner fan of an ideal I ⊂ k[x1, . . . , xn], defined by Mora and Robbiano, is a complex of polyhedral cones in Rn. The maximal cones of the fan are in bijection with the distinct monomial initial ideals of I as the term order varies. If I is homogeneous the Gröbner fan is complete and is the normal fan of the state polytope of I. In general the Gröbner fan is not complete and therefore no...
Abstract: Background and Aim: Considering that suspended particles are one of the main pollutants of air in cities. Since the prevention of contamination beyond the standard level and the economic and health issues of employees and individuals involved in the enclosed environment is very important, the research team concluded that the effect of fan coils at the dispersion of suspended particle...
