چکیده
Boston A novel device architecture that detects not only light but also its polarization could substantially reduce the number of optical components in a range of systems. Using traditional semiconductor fabrication methods, researchers at Boston University have designed a single mesa device consisting of two vertically integrated photodetectors that differentially respond to incident polarization. The monolithic device eliminates the need for several discrete components, such as polarization filters and beam splitters, thus cutting out critical alignment problems that make many optical systems difficult to manufacture.

متن کاملEnergy Cost of Physical Activities and Sedentary Behaviors in Young Children.
BACKGROUND This study reports energy expenditure (EE) data for lifestyle and ambulatory activities in young children. METHODS Eleven children aged 3 to 6 years (mean age = 4.8 ± 0.9; 55% boys) completed 12 semistructured activities including sedentary behaviors (SB), light (LPA), and moderate-to-vigorous physical activities (MVPA) over 2 laboratory visits while wearing a portable metabolic sy...
متن کاملBehavioral and Transcriptomic Fingerprints of an Enriched Environment in Horses (Equus caballus)
The use of environmental enrichment (EE) has grown in popularity over decades, particularly because EE is known to promote cognitive functions and well-being. Nonetheless, little is known about how EE may affect personality and gene expression. To address this question in a domestic animal, 10-month-old horses were maintained in a controlled environment or EE for 12 weeks. The control horses (n...
متن کاملFemale Pupils Perception of Electrical Engineering
Recent studies have focused on gender issues and women’s underrepresentation in fields such as computer science, software engineering (Camp, 1997, 2002), and information technology (Varma, 2003). This article broadens the discussion to include the field of electrical engineering (EE), in which the underrepresentation of women is even more salient than in the aforementioned fields. For example, ...

To the beneficial properties of dietary fiber in human health, several disadvantages can be added as the possible modification of the bioavailability of other drugs when administered by the oral route. In this study, the influence of glucomannan in the oral bioavailability of ethinyl estradiol (EE), when administered to female rabbits in two different dosage forms (enteric capsules and disperse...
