Magic Spots Cast a Spell on DNA Primase
The bacterial signaling molecules ppGpp and pppGpp regulate transcription initiation in response to starvation by altering RNA polymerase activity. In this issue, Wang et al. (2007) show that (p)ppGpp also inhibits DNA replication elongation by interfering with DNA primase activity. Halting replication may help cells to maintain genomic integrity during periods of transient nutrient limitation.
متن کاملRetraction of Stapel and Semin (2007). The magic spell of language: linguistic categories and their perceptual consequences.
Language is a tool that directs attention to different aspects of reality. Using participants from the same linguistic community, the authors demonstrate in 4 studies that metasemantic features of linguistic categories influence basic perceptual processes.

China is a country with significant but unevenly distributed water resources. The water stressed North stays in contrast to the water abundant and polluted South defining China's current water environment. In this paper we use the latest available data sets and adopt structural decomposition analysis for the years 1992 to 2007 to investigate the driving forces behind the emerging water crisis i...
متن کاملKhmer Spell Checker
Khmer is the official language of Cambodia. It is a complex language. Similar to Chinese, Japanese and Thai, Khmer words are written without spaces or other word delimiters. This is a major challenge in spell checking Khmer since there is no simple way to determine word boundaries. However, it is feasible to spell check Khmer. The process of spell checking Khmer is different from the spell chec...
متن کاملListen, Attend and Spell
We present Listen, Attend and Spell (LAS), a neural network that learns to transcribe speech utterances to characters. Unlike traditional DNN-HMM models, this model learns all the components of a speech recognizer jointly. Our system has two components: a listener and a speller. The listener is a pyramidal recurrent network encoder that accepts filter bank spectra as inputs. The speller is an a...
