Reasoning about agent preferences on a set of alternatives, and the aggregation of such preferences into some social ranking is a fundamental issue in reasoning about uncertainty and multi-agent systems. When the set of agents and the set of alternatives coincide, we get the ranking systems setting. A famous type of ranking systems are page ranking systems(More)
This paper describes the process of building the first tree-bank for Modern Hebrew texts. A major concern in this process is the need for reducing the cost of manual annotation by the use of automatic means. To this end, the joint utility of an automatic morphological ana-lyzer, a probabilistic parser and a small manually annotated tree-bank was explored.(More)

Knockout tournaments provide a common and important framework for structuring sporting competitions, worth billions of dollars every year in the global economy. Knockout tournaments also model a specific type of election scheme: namely, sequential pairwise elimination elections. The designer of a tournament typically controls both the shape of the(More)
OBJECTIVES Uterine sarcomas are a rare group of mesenchymal tumors with a poor prognosis and aggressive biology. Standard treatment involves surgical staging. The role of further adjuvant treatment is unclear. The goals of this study were to determine the response rates to treatment of patients with uterine sarcomas and to review the currently available(More)
OBJECTIVE To estimate the incidence of gestational trophoblastic disease in Nova Scotia and to evaluate the effect of time and maternal age on these rates. METHODS Information on women with a pathologically confirmed diagnosis of gestational trophoblastic disease was extracted from the Nova Scotia Gestational Trophoblastic Disease Registry between 1990(More)
OBJECTIVE The lack of randomized clinical data pertaining to optimal surgery and adjuvant treatment in women with high-risk histotypes of endometrial cancer has resulted in selective management based on institutional policies. The objective of this study was to assess differences in treatment strategies and their outcomes among various institutions. (More)
Low-grade serous carcinomas and serous borderline tumors, combined herein and referred to as low-grade serous tumors, show distinct molecular alterations and clinical behaviors compared with high-grade serous carcinomas. The discrimination between low-grade serous tumors and high-grade serous carcinomas can be challenging on small tissue samples, such as(More)
This paper initiates research on the foundations of ranking systems, a fundamental ingredient of basic e-commerce and Internet Technologies. In order to understand the essence and the exact rationale of page ranking algorithms we suggest the axiomatic approach taken in the formal theory of social choice. In this paper we deal with PageRank, the most famous(More)
Vacuum assisted closure and negative pressure (NP) dressings are innovative forms of wound management used in multiple fields of medicine, including surgery. We review here the current literature in this area relevant for the gynaecologist. Negative pressure dressings increase blood flow to the wound, decrease bacterial counts, decrease tension on wound(More)
