28 Scientists have spent the last century or so busily plundering the electromagnetic spectrum, adapting almost every wavelength possible for all manner of applications. We listen to music through radio waves , cook our dinners using microwaves, turn our televisions on with infrared lasers, find forged bank notes with ultraviolet light and identify broken bones with X-rays. Yet there is one reg...

An intelligent agent has multiple goals, limited resources, and a dynamic real-time task environment. Because it has many predictable and unpredictable opportunities to act, the agent must "control" its actions-it must decide which of many possible actions to execute at each opportunity over a period of time. In a given situation, the agent’s control decisions determine whether it achieves its ...

In an interesting Turkish retrospective study, conducted between 2012 and 2015, involving 1510 adults, Kekilli et al.[1] tested triple therapy (lansoprazole 30 mg b.i.d., clarithromycin 500 mg b.i.d., and amoxicillin 1 g b.i.d.), bismuth group C (lansoprazole, clarithromycin, amoxicillin, and bismuth subsalicylate 524 mg b.i.d.), and bismuth group M (lansoprazole, amoxicillin, metronidazole 500...

It is with great satisfaction that we deliver one more issue of the Brazilian Journal of Cardiovascular Surgery (BJCVS). This has been a special year for all of us of the Editorial Board, besides celebrating our 30 anniversary we are deeply restructuring the BJCVS. In July 2015, during a meeting of the Board of the Sociedade Brasileira de Cirurgia Cardiovascular (SBCCV), we decided that the adm...

The conventional method of simulating networks, i.e. packet-by-packet, always consumes many hours and often days of ‘real’ time just to simulate a few hours of ‘simulation’ time. Accelerated simulation techniques reduce the number of events simulated and decrease the time needed for an experiment. In this paper we describe our approach to accelerate simulation of a power-law aggregated ON/OFF t...

Purpose – The purpose of this contribution is to focus on an essential issue in all workplace settings where the emphasis is on productivity, time management and creativity: getting innovative, high quality work completed in time according to tight schedules – often facing serious staff shortages. The intention is not to offer an ultimate answer, but to take a different look at the issues that ...
