Mobile robots often rely upon systems that render sensor data and perceptual features into costs that can be used in a planner. The behavior that a designer wishes the planner to execute is often clear, while specifying costs that engender this behavior is a much more difficult task. This is particularly apparent when attempting to simultaneously tune many parameters that define the mapping fro...

This paper investigates the effects of a change in the margin rules of the U.S. stock market. These rules determine how much investors can borrow to leverage their investments. Since the 1929 stock market crash, margin loans have been tightly regulated by the Securities and Exchange Act Regulation T. Between 2005 and 2008, the Securities and Exchange Commission modified these margin rules becau...

OBJECTIVES To investigate the prognostic implications of p53 expression in the surgical margins of laryngeal squamous cell carcinomas. METHODS Thirty one patients with T3-4N0M0 cancers with pathologically negative margins were analyzed by immunohistochemistry (IHC) to detect expression of p53. RESULTS The p53 positive rates by IHC in the surgical margin were 16.1% (5/31). In the p53 positiv...

OBJECTIVE Examine the variation for Medicare and privately insured patients in hospital costs, payments, and contribution margins and their association with characteristics of the patients, hospitals, and hospital markets. DATA SOURCES Administrative records for 1,858 patients undergoing cardiac valve replacement surgery were obtained from 37 hospitals in 7 states for 2008. STUDY DESIGN Biv...

BACKGROUND The relationship between surgical margin and local recurrence (LR) in osteosarcoma patients with poor responses to chemotherapy is unclear. Moreover, the incidences of LR according to three different resection planes (bone, soft tissue, and perineurovascular) are not commonly known. METHODS We evaluated the incidence of LR in three areas. To assess whether there is a role of surgic...

conclusions the castings fabricated from the ringless technique with non-precious alloy are acceptable. this investing system is useable for the fabrication of fixed restorations. results after statistical evaluation, the following results were obtained: the mean vertical margin discrepancy for conventional investing was 156.72 ± 64.67µ; for the ringless technique it was 117.3 ± 26.77µ; and for...

OBJECT Atypical meningioma often recurs even after resection. As a salvage modality, radiotherapy or stereotactic radiosurgery (SRS) is attempted for this aggressive tumor. This retrospective study was performed to evaluate the efficacy of SRS that involved Gamma Knife surgery (GKS) for atypical meningioma. METHODS The authors reviewed records from 22 patients with histologically proven atypi...

PURPOSE This in vitro study evaluated and compared the vertical marginal gap of cast and milled full coverage gold copings using two margin designs (chamfer and chamfer bevel) before and after fitting adjustments. MATERIALS AND METHODS Ten impressions were made of two metal master dies (one chamfer margin, one chamfer-bevel margin) and poured twice in Type IV stone. The 20 subsequent casts wi...

The aim of the study is to evaluate the prognostic impact of the extent of submillimeter or zero surgical margin (SubMM) area among the patients who underwent liver resection for colorectal liver metastases (CRLM).The influence of suboptimal margin width of <1 mm on long-term outcome is unclear.A total of 423 liver resections for CRLM were performed at Japanese Red Cross Medical Center between ...

PURPOSE The aim of this study was to explore the relationship between chronic cigarette smoking and meibomian gland dysfunction (MGD). METHODS This study enrolled 322 smokers with MGD and 2067 non-smokers with MGD. All enrolled subjects were tested in the following sequence: Ocular Surface Disease Index (OSDI), tear film breakup time (TBUT), corneal fluorescein staining (CFS), Schirmer I test...
