DECAL: A Reconfigurable Monolithic Active Pixel Sensor for Tracking and Calorimetry in a 180 nm Image Sensor Process.

In this paper, we describe DECAL, a prototype Monolithic Active Pixel Sensor (MAPS) device designed to demonstrate the feasibility of both digital calorimetry and reconfigurability in ASICs for particle physics. The goal of this architecture is to help reduce the development and manufacturing costs of detectors for future colliders by developing a chip that can operate both as a digital silicon calorimeter and a tracking chip. The prototype sensor consists of a matrix of 64 × 64 55 μm pixels, and provides a readout at 40 MHz of the number of particles which have struck the matrix in the preceding 25 ns.

Socioeconomic factors influencing the failure to measure the blood pressure of children during clinical examinations.

The authors measured the percentage of children aged 6 through 17 whose blood pressure (BP) was not measured during recent nonemergency clinical examination and assessed the relative importance of health, ability-to-pay, language, and race-ethnic factors in determining whether BP was measured. Using a pooled dataset from the Medical Expenditure Panel Survey (MEPS) for 2006 and 2007, the authors calculated the percentage of children whose BP was not measured using a sample of children aged 6 through 17 and constructed a logistic regression model to estimate the relative importance of health, economic, and social factors in the examiner's decision to measure BP. A total of 28.

Flexible lipid bilayers in implicit solvent.

A minimalist simulation model for lipid bilayers is presented. Each lipid is represented by a flexible chain of beads in implicit solvent. The hydrophobic effect is mimicked through an intermolecular pair potential localized at the "water"/hydrocarbon tail interface.

Fatal injuries to teenage construction workers in the US.

Background: The construction industry is second only to agriculture in the annual number of fatal injuries in workers less than 18 years of age. We examined fatal injury reports for youth and adult workers to determine risk factors for injury and applicability of existing child labor regulations.

Methods: The US Occupational Safety & Health Administration (OSHA) investigation data for fatal work injuries from 1984 through 1998 were reviewed with respect to type of event, employer characteristics, and apparent violations of existing child labor laws under the Fair Labor Standards Act (FLSA).

Impact of the OSHA trench and excavation standard on fatal injury in the construction industry.

In 1989 the US Occupational Safety & Health Administration revised the excavation and trenching standard. We examined fatal injuries from trench cave-in in the construction industry for five year periods before and after the revision in the 47 US states for which data were available for both periods. There was a 2-fold decline in the rate of fatal injury after revision of the standard, which substantially exceeded the decline in other causes of fatal injury in the construction industry during the same period.
