BACKGROUND To review the outcome of using radiofrequency ablation (RFA) for patients with close resection margin during hepatectomy. METHODS From Oct 2004 to Sept 2013, 862 patients received hepatectomy for hepatocellular carcinoma (HCC) in the Department of Surgery, Queen Mary Hospital in Hong Kong. Fourteen patients received additional RFA because of close resection margin (<1 cm) during th...

Abstract Purpose Although maximal resection of wild-type GBM tumors is associated with longer survival, the association genomic alterations ability to resect disease has not been elucidated. This study aimed determine whether certain molecular are less amenable surgical and achieving a margin devoid tumor cell burden provides clinical benefit. Methods Molecular profiling 148 consecutive samples...

As a maintenance strategy to reduce unexpected failures and enable safe operation, condition-based (CBM) has been widely used in recent years. The decision criteria of CBM the literature mostly originate from statistical failure data or degradation states, few which can directly effectively reflect current state analyze condition monitoring data, measures, reliability together at same time. In ...

In the integrated power system network uncertainty can occur at any time. The transmission reliability (TRM) margin is amount of capacity that guarantees protected from instability in operating state system. calculation available transfer (ATC) should be included a deregulated to ensure safe within fair range uncertainties arise during transfer. However, TRM conserved as reflect unpredictabilit...

Introduction: Tonsillectomy is one of the most common procedures performed by Ear, Nose, and Throat surgeon.  Usually, the procedure is carried out as an inpatient surgery. With the increasing need to reduce healthcare costs, spare precious hospital beds, and shorten elective surgery lists, there is currently a trend towards performing tonsillectomy on a daycare basis.  Materials and Methods: A...

This paper presents a validation framework for collateral requirements or margins on a derivatives exchange. It can be used by investors, risk managers, and regulators to check the accuracy of a margining system. The statistical tests presented in this study are based either on the number, frequency, magnitude, or timing of margin exceedances, which are de…ned as situations in which the trading...

In this communication, hexapod tripod gaits for straightline motion and crab walking are derived. Mathematical relations that express the stability margin, the stride length, and the duty factor are formulated for straight-line motion and for crab walking, respectively. The derived results provide tripod gaits of the hexapod for walking with a prescribed stability margin either over perfect ter...

abstract marketing element’s contrastive behaviors toward price risk had considerable effect on marketing margin in a way that transferring increase in price to final consumer, reduces purchasing power and so consumption amounts of consumers. present study evaluated effective parameters on marketing margin in 2 level of ranch-processing and processing- retail of beef and lamb with consideration...

In the US, community technology centers (CTC) are a policy response to facilitate the diffusion of information and communication technologies (ICT) to citizens who might otherwise lack access to these resources. The implicit assumption guiding CTC initiatives is that access to ICT will improve the life chances of the individuals who become involved in these centers. It is, however, prudent to e...
