With today 's entry I begin my ninth year oi writing columns in your school newspaper for the makers oi Marlboro Cigarettes. Nine years, I believe you will agree, is a long time. In fact, it took only a little longer than nine years to dig the Suez Canal , and you know what a gigantic under taking t h a t was! To be sure, the work would have gone more rapidly had the shovel been invented at tha...

BACKGROUND Members of the subfamily Galleriinae have adapted to different selective environmental pressures by devising a unique mating process. Galleriinae males initiate mating by attracting females with either chemical or acoustic signals (or a combination of both modalities). Six compounds considered candidates for the sex pheromone have recently been identified in the wing gland extracts o...

Legitimate labour migration has, no doubt, got much attention in various economies and force irrespective of gender tempt for diverse employment. Industrial employment job concentration industrial cluster always provoke work driven migration. People relocate their whereabouts based on secure livelihoods. And, economic centralization targeted thus associate each other with exception Bangladesh. ...

Corpus-based grz.mmar induction relies on using many hand-parsed sentences as training examples. However, the construction of a training corpus with detailed syntactic analysis for every sentence is a labor-intensive task. We propose to use sample selection methods to minimize the amount of annotation needed in the training data, thereby reducing the workload of the human annotators. This paper...

We describe a trainable and scalable summarization system which utilizes features derived from information retrieval, inibrmation extraction, and NLP techniques and on-line resources. The system con> bines these features using a trainable feature combiner learned from summary examples through a machine learning algorithm. We demonstrate system scalability by reporting results on the best combin...

This paper explores the options available in the formal definitions of generation and, parasit ically, translation, with respect to the assumed necessity for using a single g rammar for analysis and synthesis. This leads to the consideratiOn of different adequacy conditions re la t ing the input to the generation process and the products of analysis of its Output. I. A SCHEMATIC DEFINITION OF ~...

The metabolism of C ~4-1abeled pyruvate in normal and neoplastic tissue has been studied both in vitro (8, 10, 13, 14) and in vivo (3). Although the experiments of the Coris (6) and Warburg (1~) indicated a net production of lactate by tumors in vivo and in vitro, the metabolism of trace quantities of C14-1abeled pyruvate was not found to be significantly different in tumors and other tissues i...

The ease with which it is possible to detect lymphokine-l ike activities in the supernates of cul tured mur ine cells has led to the description of a large n u m b e r of illdefined factors which may or may not be of biological significance. In recent years, the si tuat ion has become aggravated by the increasing n u m b e r of in vitro assays for putat ive lymphokines with insufficient a t ten...

1 I n t r o d u c t i o n In recent years there has been an at tempt to reconcile the theoretical work on reasoning about action with the realization of agents, in particular mobile robots. Such a field of research has been referred to as Cognitive Robotics [10]. A mobile robot can indeed be regarded as an intelligent agent, tha t is designed both to achieve high-level goals and to be able to p...

It has been shown in the authors' laboratory that a low level of DL-ethionine, alone or in combi nation with certain amino acids, decreased carcass weight and inhibited the growth of Sarcoma R-l in male Wistar rats (3). The degree of tumor inhi bition, however, was not as great as that observed with comparable levels of ethionine administered to Long-Evans rats bearing the Jensen sarcoma or the...
