To the Editor: The recent review by Waters and Nelson ‘Are all nonthymidine analogue backbones appropriate for treating antiretroviral-naı̈ve patients?’ (1) states incorrectly that the rates of hypersensitivity (HSR) in the Zodiac Study were significantly higher with abacavir (ABC) once daily than with ABC twice daily (8 vs. 5%, p < 0.02). In fact, the rates of suspected ABC HSR in the Zodiac St...

A procedure for periodic quality assurance of a video surface imaging system is introduced. AlignRT is a video camera-based patient localization system that captures and compares images of a patient's topography to a DICOM-formatted external contour, then calculates shifts required to accurately reposition the patient. This technical note describes the tools and methods implemented in our depar...

This is another of the papers presented at the conference on 'Violence' organised under the auspices of the London Medical Group. Sylvia Winterbottom, who is based in the Casualty Department of Bolton Royal Infirmary, relates her experiences with various types of violent patients she meets daily in her work. She feels that many factors are to blame for the ever increasing violence but is more i...

A 67-year-old woman presented to our clinic with 5 years history of intermittent dysphasia. She described dysphasia during the intake of solid food and sometimes with liquid food. She did not note abdominal pain, hematemesis, or melena, but in the past two years, she noted a weight loss of 5 kgs. Her medical history was significant only for hypertension, which was controlled by 100 mg daily dos...

Author Steven Zeisel believes DEA could induce fetal neural abnormalities in humans, too. “It’s hard to estimate human exposure, but we believe the mice had exposures about ten times higher,” he says, assuming that people bathe and shampoo daily with DEA-containing products, and use DEAcontaining sunscreen. “There’s no reason to believe we wouldn’t see similar effects in humans.” The authors no...

One of the ground tools used to operate the Mars Exploration Rovers is a mixed-initiative planning system called MAPGEN. The role of the system is to assist operators building daily plans for each of the rovers, maximizing science return, while maintaining rover safety and abiding by science and engineering constraints. In this paper, we describe the MAPGEN system, focusing on the mixed-initiat...

Smartphone notifications frequently interrupt our daily lives, often at inopportune moments. We propose the decision-on-information-gain model, which extends the existing data collection convention to capture a range of interruptibility behaviour implicitly. Through a six-month in-the-wild study of 11,346 notifications, we find that this approach captures up to 125% more interruptibility cases....

abstract accurate prediction of river flow is one of the most important factors in surface water recourses management especially during floods and drought periods. in fact deriving a proper method for flow forecasting is an important challenge in water resources management and engineering. although, during recent decades, some black box models based on artificial neural networks (ann), have bee...

evaporation is one of the most important components of hydrologic cycle.accurate estimation of this parameter is used for studies such as water balance,irrigation system design, and water resource management. in order to estimate theevaporation, direct measurement methods or physical and empirical models can beused. using direct methods require installing meteorological stations andinstruments ...

This study focused on analyzing language function, especially referential function. function used in many kinds of communication, including daily communication. Therefore, this aimed to analyze the as well its elements L’Oreal Paris advertisements. In regards aims study, two theories were applied. The theory proposed by Jakobson (1980: 82) was analyzed transcripts 19 advertisements videos Paris...
