Disregarding experiments in simulated machine translation, which in place of a computer employs a person with no knowledge of the language to be translated acting in accordance with a set of given rules, only three actual attempts have been made, to my knowledge, to translate in this way. These were by the Institute of Languages and Linguistics of Georgetown University in association with the I...

Today we’ll describe a new family of codes, called algebraic-geometry codes. These codes generalize Reed-Solomon codes and yield surprisingly good codes over constant sized alphabets. We’ll motivate the codes from two points of view. First we’ll show how they challenge the “conjectured converse of the Gilbert-Varshamov bound”. We’ll then motivate the codes from the algebraic perspective. The re...

Today, advanced technological products often employ information and communication technology to enhance their functionality and quality. Therefore, nowadays software plays an important role in the control of many technical systems such as electrical and mechanical devices, technical processes in the chemical industry, or a modern automobile. In the future, software-intensive systems are in addi...

Objective: Bipolar disorder is a severe mental disorder, and its prevalence is around 1% to 2%. Despite a vast literature around bipolar disorder, the reasons of its nonadherence and rehospitalization is still obscure. Several symptoms of bipolar disorder include changes in activity level, cognitive abilities, speech, and vegetative functions, such as sleep, sexual activity, as well as aggressi...

O composto 4-(4-nitrobenzilidenoamino)fenol foi utilizado em duas estratégias que permitem uma detecção altamente seletiva de F e CN. Primeiramente, observou-se que o composto em acetonitrila age como um quimiossensor cromogênico devido ao fato de que ânions básicos levam ao seu desprotonamento (solução incolor), resultando numa solução colorida contendo fenolato. A detecção seletiva de CN sobr...
