چکیده
Much of our work has focused on the design and implementation of a Unix Consultant (UC) program. This system carries out a dialog in English to answer user 's queries about the UNIX operating system. UC comprises a natural language parsing and generation system, a goal analyzer that hypothesizes user 's goals in different contexts, a user model component that allows UC to tailor answers to the user 's level of expertise, a conversational planner that allows flexible reaction to user requests, a response formation mechanism that enables from of response to be concise and appropriate, and (iv) a knowledge-intensive planner that allows UC produce complex plans and warnings of potential plan failures

The KL-UCB Algorithm for Bounded Stochastic Bandits and Beyond
This paper presents a finite-time analysis of the KL-UCB algorithm, an online, horizonfree index policy for stochastic bandit problems. We prove two distinct results: first, for arbitrary bounded rewards, the KL-UCB algorithm satisfies a uniformly better regret bound than UCB and its variants; second, in the special case of Bernoulli rewards, it reaches the lower bound of Lai and Robbins. Furth...
متن کاملبررسی اثر عصارۀ پلاکتی مشتق از خون بندناف بر تکثیر سلولهای تکهستهای خون بندناف در آزمایشگاه
Background and Objective: In spite of promising results in treatment of blood diseases by umbilical cord blood cell transplantation, low number of derived stem cells has been a matter of concern. Since platelets extracts has been introduced as a potent mesenchymal stem cell culture supplement, the purpose of current study was to investigate the probable effects of umbilical cord blood platelet ...
متن کاملCEACAM1: a novel urinary marker for bladder cancer detection.
BACKGROUND Carcinoembryonic antigen-related cell adhesion molecule 1 (biliary glycoprotein; CEACAM1) is expressed in normal bladder urothelium and in angiogenically activated endothelial cells, where it exhibits proangiogenic properties. OBJECTIVE The aim of this study was to evaluate the value of urinary CEACAM1 for detection of urothelial carcinoma of the bladder (UCB). DESIGN, SETTING, A...
متن کاملStudy of telomerase activity, proliferation and differentiation characteristics in umbilical cord blood mesenchymal stem cells
In recent years, considerable advances have been made in the field of regenerative medicine. Unlikeembryonic stem cells, which pose the problems of ethical concerns and cause severe immunological reactions as well as neoplasma formation after transplantation, umbilical cord blood is a primitive source ofmesenchymal stem cells that covers the benefits of both embryonic and adult stem cells. It h...
متن کاملInteractions of unconjugated bilirubin with bile salts.
The rate of peroxidation of unbound, unconjugated bilirubin (UCB) was used to assess the interactions of UCB with four taurine-conjugated bile salts at pH 8.2, 37 degrees C, and an ionic strength of 0.15. Each of the four structurally different bile salts markedly decreased the rate of peroxidation of UCB in the presence of horseradish peroxidase (HRP); 30% of UCB was bound even at low, premice...
متن کاملIntra-osseous Co-transplantation of CD34-selected Umbilical Cord Blood and Mesenchymal Stromal Cells
Human mesenchymal stromal cells (MSC) have been shown to support the growth and differentiation of hematopoietic stem cells (HSC). We hypothesized that intra-osseous (IO) co-transplantation of MSC and umbilical cord blood (UCB) may be effective in improving early HSC engraftment, as IO transplantation has been demonstrated to enhance UCB engraftment in NOD SCID-gamma (NSG) mice. Following non-l...
