Successful analysis in SAS often requires lengthy repetitive steps; the same code is executed on numerous data points. Iteration of SAS code is often easily achieved with the use of Macro Arrays. The programmer can employ numerous methods for creating these arrays, as well as choosing among different structural designs. PROC SQL and the SAS DATA step can each provide clear advantages to the cre...
Our objectives were to evaluate the performance of an ear-attached automated estrus detection (AED) system (Smartbow; Zoetis) that monitored physical activity and rumination time, characterize AED alert features (i.e., timing duration). Lactating Holstein cows (n = 216) commenced a protocol for synchronization at 50 ± 3 DIM or 18 d after artificial insemination. For 7 induction luteolysis with ...
A 31-year-old man came to the Veterans Administration Medical Center after 3-4 years of right frontal headaches that had been increasing in freq uency and intensity. No other complaints were noted . There was no history of migraine and family history was unremarkable. Physical examination including neurologic testing was completely normal. Init ial CT examination (not shown) was suspicious for ...
PURPOSE This study aimed to evaluate the effect of the placement of wide-diameter implants on bone stress concentrations and marginal bone loss in the first molar region. Study hypotheses held that increasing implant diameter would decrease peri-implant bone stress levels, but that statistically significant reductions in clinical bone loss would either (1) not be observed for any implant diamet...
Child maltreatment affected nearly 700,000 children in the United States in 2012. Child maltreatment is broken down into four main divisions according to the Centers for Disease Control (CDC): physical abuse, sexual abuse, emotional abuse, and neglect. South Carolina’s ranking for child well-being is among the poorest at 45th in the nation. Earlier recognition and intervention for a child victi...
BACKGROUND Parkinson's disease (PD), the second most frequent neurodegenerative disorder at old age, can be caused by elevated expression or the A53T missense mutation of the presynaptic protein alpha-synuclein (SNCA). PD is characterized pathologically by the preferential vulnerability of the dopaminergic nigrostriatal projection neurons. METHODOLOGY/PRINCIPAL FINDINGS Here, we used two mous...
The advantages of a horizontal half-wave resonant antenna f or very-low-frequency propagation experiments lie in its r elatively simple and inexpensivc construction and in its radiation pattern which is maximum in the vertical direction. The radiation fields of this type of antenna located at the s urface of a condu cting earth consist of: 1, A horizontally polarized space-wave field radiated i...
With all the different therapies available to treat a medical condition, doctors must evaluate how the different products perform on different treatment goals in order to select the appropriate therapy for a patient. This evaluation process is used to determine which product is best when treating a particular patient. This paper will discuss the collection and analysis of the treatment goal dat...
In the clinic, tremor is diagnosed during a time-limited process in which patients are observed and the characteristics of tremor are visually assessed. For some tremor disorders, a more detailed analysis of these characteristics is needed. Accelerometry and electromyography can be used to obtain a better insight into tremor. Typically, routine clinical assessment of accelerometry and electromy...
