We have developed a technique to characterize software developers- styles using a set of source code metrics. This style fingerprint can be used to identify the likely author of a piece of code from a pool of candidates. Author identification has applications in criminal justice, corporate litigation, and plagiarism detection. Furthermore, we can identify(More)
OBJECTIVE The purpose of this study was to compare MR imaging findings with histologic findings of either hippocampal sclerosis or gliosis in patients with intractable temporal lobe epilepsy requiring surgery and to correlate MR imaging findings with seizure outcome after surgery and with clinical parameters such as febrile seizure history. MATERIALS AND(More)
To establish whether alterations in insulin action and secretion and their relationship to body fat distribution occur early in the course of developing obesity, we studied 14 obese adolescent girls [13.2 +/- 0.7 yr, body mass index (BMI) 32 +/- 1.4], 16 nonobese young women (24.0 +/- 0.6 yr, BMI 21.0 +/- 0.9). Insulin action was assessed by a sequential(More)
George Rosen's "From Medical Police to Social Medicine" is a collection of essays he wrote during the past thirty years, ranging, as the title states, from medical police to social medicine. The underlying thesis of many of the essays is that the theories, the policies, and the practices of public health can be understood fully only against the backdrop of(More)
Using a 1.5-T system, we investigated the contrast in MR images of the uterus using a synthetic imaging program that was capable of producing images with TR values of 20 to 10220 ms and TE values of 1 to 511 ms. Synthetic images were calculated from images obtained on six normal women of reproductive age. The synthesized uterine images were essentially(More)
Although a single perinatal or postnatal event may be directly correlated to intraventricular hemorrhage (IVH) in some infants, in other infants IVH may be related to a series of insults. Asphyxia, hypotension, and a pressure-passive low cerebral blood flow (CBF) may lead to an infarction. Subsequent events known to cause sudden rises in the CBF may then(More)
—As multicore and heterogeneous multiprocessor platforms replace uniprocessor systems, software programs must be designed with a greater emphasis on concurrency. Threading has become the dominant paradigm of concurrent computation in the most popular programming languages. Large threaded programs are known to be difficult to implement correctly, comprehend,(More)
To improve the efficiency of magnetic resonance imaging of the total spine, the authors developed a coil holder and marker system to accurately localize the level of the spine imaged. The patient's external auditory canal and the alignment light on the imager are lined up with marks on the coil holder. The spine is then imaged in three segments by using a(More)
Thallium-201 ((201)T1) myocardial perfusion imaging allows definition of zones of myocardial infarction and ischemia. The temporal changes in sequential quantitative (201)T1 infarct imaging was studied 4 and 24 hours in dogs subjected to closed-chest anterior wall myocardial infarction. A temporal decrease in (201)T1 imaged infarct areas was noted in 10 of(More)
