Medicina
Paciente de 72 anos de idade, feminino, apresenta dor abdominal há 3 dias no hipocôndrio direito, com aumento discreto da frequência cardíaca (102 bpm), PA 140/80 mmHg (é usuário de losartan). Ao exame, apresenta abdômen doloroso à direita com distensão, ruídos peristálticos diminuídos. Apresentou uma evacuação escura há dois dias. RX de abdômen normal, ultrassonografia de abdômen mostra colédoco e vesícula biliar normais. Exames mostram leucócitos 12.100/mm³ com 75% de polimorfonucleares, ureia 80 mg/dl, creatinina 1,3 mg/dl, íons normais, tomografia de abdômen mostra alça de delgado espessa com sinais de trombose de veia mesentérica. A paciente necessita de uso de analgésicos de 6 em 6 horas (tramadol) e é portadora de Ca de mama em regressão (fez quimioterapia há 3 meses).

New Research Advances Voice Security Technology
ScienceDaily (Mar. 11, 2010) — Most people are familiar with security technology that scans a person's handprint or eye for identification purposes. Now, thanks in part to research from North Carolina State University, we are closer to practical technology that can test someone's voice to confirm their identity.
"The big picture is speaker authentication by computer," says Dr. Robert Rodman, professor of computer science at NC State and co-author of a new paper on the subject. "The acoustic parameters of the voice are affected by the shape of the vocal tract, and different people have different vocal tracts," Rodman explains. "This new research will help improve the speed of speech authentication, without sacrificing accuracy."
Rodman explains that speech authentication could have a host of applications in this age of heightened security and mobile electronics. "Potential users of this technology include government, financial, health-care and telecommunications industries," Rodman says, "for applications ranging from preventing ID theft and fraud to data protection."
Current computer models that are used to compare acoustic profiles, effectively evaluating whether a speaker is who he says he is, may take several seconds or more to process the information, which is still too long for the technology to gain widespread acceptance. "In order for this technology to gain traction among users," Rodman says, "the response time needs to improve without increasing the error rate."
To address this problem, Rodman and his fellow researchers modified existing computer models to streamline the authentication process so that it operates more efficiently. "This is part of the evolution of speech authentication software," Rodman says, "and it moves us closer to making this technology a practical, secure tool."
The research was co-authored by NC State's Rodman; Rahim Saeidi, Tomi Kinnunen and Pasi Franti of the University of Joensuu in Finland; and Hamid Reza Sadegh Mohammadi of the Iranian Academic Center for Education, Culture & Research.
The research, "Joint Frame and Gaussian Selection for Text Independent Speaker Verification", will be presented at the International Conference on Acoustics, Speech and Signal Processing (ICASSP) in Dallas, March 14-19. The research was funded, in part, by the Centre for International Mobility.
NC State's Department of Computer Science is part of the university's College of Engineering.
