متن کاملThe Weaver System for Document Retrieval
This paper introduces Weaver, a probabilistic document retrieval system under development at Carnegie Mellon University, and discusses its performance in the TREC-8 ad hoc evaluation. We begin by describing the architecture and philosophy of the Weaver system, which represents a departure from traditional approaches to retrieval. The central ingredient is a statistical model of how a user might...
متن کاملCTCF: Master Weaver of the Genome
CTCF is a highly conserved zinc finger protein implicated in diverse regulatory functions, including transcriptional activation/repression, insulation, imprinting, and X chromosome inactivation. Here we re-evaluate data supporting these roles in the context of mechanistic insights provided by recent genome-wide studies and highlight evidence for CTCF-mediated intra- and interchromosomal contact...
متن کاملFunctional Analysis of the weaver Mutant GIRK2 K+ Channel and Rescue of weaver Granule Cells
In the neurological mutant mouse weaver, granule cell precursors proliferate normally in the external germinal layer of the cerebellar cortex, but fail to differentiate. Granule neurons purified from weaver cerebella have greatly reduced G protein-activated inwardly rectifying K+ currents; instead, they display a constitutive Na+ conductance. Expression of the weaver GIRK2 channel in oocytes co...
متن کاملFrom Weaver to the ALPAC Report
This paper presents a sample pertaining to the creation and the use of words in the field of Natural Language Processing (NLP) in the years 1949-1966. These words have been statistically sorted and the results could be taken as a proof that electronic processing of linguistic data leads to the diffusion of clear and concise words for describing a complex concept which would need a circumlocutio...
