Acute graft-versus-host disease (GVHD) is the most frequent, morbid complication following allogeneic hematopoietic stem cell transplantation (HSCT). Its clinical toxicity, requirement for intensive immunosup-pressive management, and associated infections lead to the greatest risks of nonrelapse mortality in HSCT recipients. In acute GVHD, donor-derived T lymphocyte-mediated alloreactivity is c...

in this paper coupled nonlinear equations of motion of a suspended cable with time dependent tension and velocity are derived by using hamilton’s principal. a modal analysis for a stationary sagged cable is initially carried out in order to identify the dynamic system. the natural solution is directed to compute the natural frequencies and mode shapes of the free vibration of a suspended cable....

in the aftermath of the 1994 northridge, california, earthquake. a significant number of steel moment resisting structural systems were damaged. many studies and researches have been conducted to improve the seismic performance of structures after the catastrophe. one of the proposed connections for special moment-resisting frames included aisc-358 is kaiser bolted bracket moment connection, br...

Modeling and Wrench feasible workspace analysis of a spatial cable suspended robots is presented. A six-cable spatial cable robot is used the same as Stewart robots. Due to slow motion of the robot we suppose the motion as pseudostatic and kinetostatic modeling is performed. Various workspaces are defined and the results of simulation are presented on the basis of various workspaces and app...

There are two types of nodes, called “spouts” and “bolts”. A spout is a source of streams (sequences of tuples). In case of the KBA track, a spout would read document data from the provided KBA corpus and emit them as a stream. A bolt receives any number of input streams, does some processing, and may emit new streams. For the KBA track, bolts would determine whether inbound documents from the ...

Given the deformation and instability of layered floor weakly cemented soft rock roadway, taking mining roadway Meihuajing Mine as engineering background, mechanism control measures surrounding under different stratum combination conditions are studied by using methods field investigation, numerical calculation test. The results show that: (1) characteristics in roadways significant, structure ...

Mineral resources are one of the main energy sources used in industrial production. While economy is going up, mining coal mines and other mineral has also intensified. With deepening mining, difficulty increased. In order to ensure safe production relevant enterprises, it necessary vigorously apply supporting technology excavation reduce occurrence accidents area. Based on this, this paper, ba...

This paper addresses the cable tension distributions of a cable-driven parallel robot with non-negligible cable mass for large dimension mechanisms. A well-known model which describes the profile of a cable under the action of its own weight allows us to take the cable sags into account. In addition, an approach to computing the cable tensions is presented, in which there are two major steps to...

MSS. lntended for publication and books, etc., intended for review should be sent to the Editor of ScIENcE, Garrison-onHudson, N. Y. THE FACTORS OF SAFETY IN ANIMAL STRUCTURE AND ANIMAL ECONOMY1 THE living animal body is like a machine in action. Like a machine its structures are subject to a variety of stresses, and like a machine the work is accomplished by an expenditure of energy derived fr...
