There exists a fundamental trade-off between the spectral resolution and the efficiency or throughput for all optical spectrometers. The primary factors affecting the spectral resolution and throughput of an optical spectrometer are the size of the entrance aperture and the optical power of the focusing element. So far, the collective optimization of the above mentioned has proven difficult. He...
OBJECTIVE The present study investigated whether high school grades can predict medical school grades after controlling for the effects of demographics and entrance examination scores. MATERIAL AND METHOD The authors used hierarchical multiple regression analyses to predict medical school grades of 223 medical students in the 1997 entering class of the Faculty of Medicine Siriraj Hospital, Th...
1. In the liver of portal cirrhosis there is a far freer communication between the arterial and portal currents than in the normal liver. 2. Factors contributing to the increased portal pressure in portal cirrhosis are (1) the direct communication of the arterial pressure to the portal vessels through dilated capillaries, (2) the larger volume-flow of the hepatic artery in proportion to the por...
abstract background: for treatment verification in radiation therapy. several physical characteristics of scanningliquid filled ionization chamber epid (slic-epid) including: extra build-up layer,reproducibility and uniformity, and noise level were investigated.electronic portal imaging devices (epids) have found an outstanding positionmaterials and methods: equilibrium, 1-30 mm white water mat...
This article brings out the improved thought of college admission system reform based on parallel will: College Admission Mode of Multiple Choices Based on Internet,CAMMCBI。We use the absorbing Markov analysis method to establish the student scores and college level sequence model of absorbing Markov chain, analysis CAMMC BI admission mechanism problem from the angle of dynamic. Reform of Colle...
The spatial stability analysis of two dimensional, steady channel flow is investigated in the downstream entry zone. A model based on previous work, is presented for the base flow, which represents a small deformation of plane Poiseuille flow. The base flow evolution towards the fully developed state comes from the experimental and theoretical study of M. Asai and J.M. Floryan ”Certain aspects ...
T his paper evaluates the entrance capacity and queueing delay for Automated Highway Systems through use of simulations and analytical modeling. Queueing statistics are also used to determine the sustainable capacity of alternative concepts, taking trip length distribution and spacing between ramps into consideration. Based on safety-spacing head ways (produced in a separate analysis), the mos...
DEVELOPMENTAL anomalies of the eye in the region of the optic disc are commonly divided into two groups: those in which failure of coaptation occurs within the optic nerve sheath and those showing lesions of the peripapillary choroid or sclera. With the exception of the small holes sometimes seen on the anterior surface of the optic disc, which are probably related to aberrant formation of Berg...
A lmost 80% of postprandial glucose uptake resides in skeletal muscle (1). Hence, development of skeletal muscle insulin resistance is a hallmark of type 2 diabetes. Muscle is an ambiguous organ with respect to substrate selection. To fuel muscle contraction, both glucose and fatty acids can be oxidized. Glucose first needs to enter the muscle cells via insulin-mediated GLUT4-dependent transmem...
This paper describes the Question Answering for Machine Reading (QA4MRE) Entrance Exams at the 2013 Cross Language Evaluation Forum. The data set of this task is extracted from actual university entrance examinations as-is, and therefore includes a variety of topics in daily life. Another unique feature of the Entrance Exams task is that questions are designed originally for testing human exami...
