The current clinical management of abdominal aortic aneurysm (AAA) disease is based to a great extent on measuring the aneurysm maximum diameter to decide when timely intervention is required. Decades of clinical evidence show that aneurysm diameter is positively associated with the probability of rupture, but that other parameters may also play a role in causing or predisposing the AAA to rupt...

In this paper, we study the recognition complexity of discrete geometric 2gures (rectangles, squares, circles, ellipses) on a retina by diameter-limited and order-restricted perceptrons. We construct a diameter-limited recognition perceptron for the family of rectangles, beginning with local con2gurations, which is di6erent from the one shown by Minsky et al. (Perceptrons: An Introduction to Co...

BACKGROUND Camellia sinensis is the source of tea leaves and it is an economic crop now grown around the World. Tea seed oil has been used for cooking in China and other Asian countries for more than a thousand years. Tea is the most widely consumed beverages after water in the world. It is mainly produced in Asia, central Africa, and exported throughout the World. Some engineering properties (...

In parallel transmission system, the wide diameter has become an important factor to measure transmission efficiency instead of the diameter. The minimum distance diagram of a directed doubleloop network yields an L-shaped tile, an L-shaped tile can be described by four geometric parameters: a, b, p and q, let m1⁄4a–p, n1⁄4b q, the L-shaped tiles can be classified into 4 types according to the ...

Concentrations of endotoxin in urban air pollution have not previously been extensively characterized. We measured 24-hr levels of PM10 (particulate matter < 10 microm in aerodynamic diameter) and the associated endotoxin component once every 6 weeks for 1 year in 13 communities in Southern California. All the samples collected had detectable PM10 and endotoxin levels. The geometric mean PM10 w...

OJSC “BSW–Management Company of the Holding “BMC”, non-contact systems for measuring outer diameters products are widely used geometric dimensions. Diameter measurement to obtain reliable, true and accurate measurements. The method that provides continuous non – contact control these is light -and dark diameter. To ensure reliability results, diameter must undergo metrological calibration. Cali...

PURPOSE Unlike standard dental implants, the stabilization of orthodontic microscrews removed after treatment is done without osseointegration and achieved by several components: cortical bone thickness (CBT), microscrew geometry, and drilling depth. The purpose of this study was to evaluate 10 different microscrews and the influence of their geometric parameters with different CBT and drilling...

Rodents have been widely used to study the environmental or therapeutic impact of inhaled particles. Knowledge of airway morphometry is essential in assessing geometric influence on aerosol deposition and in developing accurate lung models of aerosol transport. Previous morphometric studies of the rat lung performed ex situ provided high-resolution measurements (50-125 μm). However, it is uncle...

Abstract. Secondary organic aerosol (SOA), formed through oxidation of volatile compounds (VOCs), displays complex viscosity and phase behaviors influenced by temperature, relative humidity (RH), chemical composition. Here, the efficacy a multi-stage electrical low-pressure impactor (ELPI) for indirect water uptake measurements was studied ammonium sulfate (AS) aerosol, sucrose ?-pinene-derived...
