This study focuses on how to determine the skip-stop scheduling for a congested urban transit line during the morning rush hours. A transit schedule with uneven headways and skip-stop operations is adopted to match the time-dependent demands and accelerate the circulative utilizations of vehicles. This schedule allows the buses to run on unequal vehicle-departure intervals and to skip some stat...

BACKGROUND Lateral cervical lymph node metastasis without central lymph node (CLN) metastasis is not infrequent in papillary thyroid cancer (PTC). This study was designed to investigate the frequency and pattern of skip metastasis in PTC. METHODS We reviewed 131 patients who underwent total thyroidectomy with CLN dissection and selective lymph node dissection. Tumor location was classified in...

We present skip-splay, the first binary search tree algorithm known to have a running time that nearly achieves the unified bound. Skip-splay trees require only O(m lg lg n + UB(σ)) time to execute a query sequence σ = σ1 . . . σm. The skip-splay algorithm is simple and similar to the splay algorithm.

OBJECTIVE This study was performed to investigate the frequency and pattern as well as the predictive factors of skip metastasis (lateral cervical lymph node metastasis without central lymph node metastasis) in papillary thyroid carcinoma (PTC). METHODS 450 PTC patients who received total thyroidectomy with central neck dissection(CND) combined with modified radical lateral neck dissection(LN...

We present a method for proving data refinement in the presence of low-level pointer operations, such as memory allocation and deallocation, and pointer arithmetic. Surprisingly, none of the existing methods for data refinement, including those specifically designed for pointers, are sound in the presence of low-level pointer operations. The reason is that the low-level pointer operations allow...

Pointers (arrows and symbols) are frequently used in biomedical images to highlight specific image regions of interest (ROIs) that are mentioned in figure captions and/or text discussion. Detection of pointers is the first step toward extracting relevant visual features from ROIs and combining them with textual descriptions for a multimodal (text and image) biomedical article retrieval system. ...

A 3-month-old short haired pointer with crusty local alopecia around the eyes was presented to SmallAnimal Hospital of Tehran University. Scraping and biopsy were obtained from lesions of affected area.Notoedres sp. was diagnosed in skin scraping by parasitologic examination. Furthermore, histopathology oflesions demonstrated moderate hyperplastic epidermis, parakeratosis and acanthosis.

Array-Range Analysis computes at compile time the range of possible index values for each array-index expression in a program. This information can be used to detect potential out-of-bounds array accesses and to identify non-aliasing array accesses. In a language like C, where arrays can be accessed indirectly via pointers, and where pointer arithmetic is allowed, range analysis must be extende...
