Gray and Szalay [1] documented the data avalanche problem in the sciences in which improvements in physical instruments and better data pipelines lead to an exponential growth in data size. Paralleling this exponential trend is the accumulation of data at multiple, autonomous data sources. Exploring the resulting massive, widely-distributed data is of immense scientific value: as Gray and Szala...

BACKGROUND/PURPOSE Perineal ectopic anus in female infants is not a very uncommon congenital anomaly. The close proximity of the ectopic anus with the vulva and the stenosed opening seen in large majority of cases necessitate some form of surgical correction. A variety of surgical procedures like cutback, posterior anal transposition, PSARP, or ASAPR, with or without diverting colostomy have be...

IEEE 802.11n is a newly emerging wireless standard which, relative to former 802.11 protocols, such as 802.11a/b/g, has a number of new mechanisms that enable multifold increases in transmission speeds. These new mechanisms include multipleinput-multiple-output (MIMO) transmission schemes as well as the option for channel bonding two 20MHz channels into a single 40MHz channel. Furthermore, 802....

The energy requirement of vacuum membrane distillation (VMD) with or without recirculation was modelled using both experimental results and theoretical data. The trends are generally consistent between the theoretical and experimental data. Thermal energy contributes the most to the total energy required for the VMD process. To lower the thermal energy cost, waste heat resource and heat recover...

Background: Anxiety following casting is an unrecognised complication that results in frequent visits to fracture clinic in the UK. There is a paucity of research regarding this complication. Failure to recognise Cast Anxiety (CA) leads to increased visits, frequent cast changes and possible failure of treatment despite no objective problems with the cast. Prior research has suggested a possibl...

Aveh archaeological site, which has prepared the necessary background for the archaeological studiesafter having been identified and registered, is located in Saveh Plain, and it is one of the less-known sitesin the Iranian Central Plateau. The chronological sequence of this site extends from prehistoric periodstill Timurid time. It is worth mentioning that here, except for the Islamic settleme...

Teh aim of dis work is to provide insight into alcohol-kerosene fuels and their promising use as an alternative in commercial aviation. A detailed chemical and physical experimental analysis is drawn, wif a focus on teh advantage of teh isopropanol-kerosene blend. Despite reported beneficial isopropanol effects on retarding fuel combustion, knocking prevention, and much lower emissions, few...

Background: Genu valgum usually originates from a deformity of distal femur that is often corrected by distal femoralvarus osteotomy. The osteotomy includes both components of angulationcorrection and translation because the siteof osteotomy is not commonly at the apex of deformity. Improvement of patellar tracking not only depends on valguscorrection, but also it may be partially due to centra...

Introduction: Adaptive response is one of the important concepts in radiobiology. The present report aimed to transfer the radio-adaptation via serum. Material and Methods: In total, 50 male adult Wistar rats were randomly divided into 6 groups, including control, serum control, low-dose (100cGy), low-dose/lethal, serum/lethal, and lethal (8G...

The topic of my dissertation research is Bayesian methods in the social sciences. There will be several parts to the dissertation. One part, the focus of this proposal, is a novel method called tuned Bayesian model averaging (tBMA) that modifies Bayesian model averaging (BMA) by using the data to inform the prior specification. BMA is a tool that accounts for model uncertainty in typical regres...
