A 0.12 μW power dissipation quartz oscillator with 32,768 Hz frequency was designed and fabricated. Stability of the oscillator versus power supply and temperature variations was measured. The design is suitable for the role of the RTC (real-time clock) or main system clock in low-power, battery-powered and energy harvesting systems.

BACKGROUND The INDEPTH Training & Research Centres of Excellence (INTREC) collaboration developed a training programme to strengthen social determinants of health (SDH) research in low- and middle-income countries (LMICs). It was piloted among health- and demographic researchers from 9 countries in Africa and Asia. The programme followed a blended learning approach and was split into three cons...

BACKGROUND Perceived health status indicates people's overall perception of their health, including both physical and psychological dimensions. The aim of this study was to examine the determinants of self-perceived health for Canadians aged 40 and older using data from the Canadian Community Health Survey (2010). METHODS Multiple logistic regression models were employed to identify factors a...

OBJECTIVE To examine disparities in park availability, features, and characteristics by income and the percentage of foreign-born population within a predominately-Hispanic border community. METHODS This study occurred in 2010-2011 in El Paso, Texas. All census tracts (n=112) were categorized as low, medium, or high income and percent foreign-born. The number of parks intersecting each tract ...

OBJECTIVES To identify low-income working families' health challenges and understand their barriers and facilitators to navigating those challenges. METHODS We conducted a focused ethnographic study in a food bank in Montreal, Quebec. Using purposeful sampling, we recruited participants who had at least one employed family member and one live-in child. Sensitizing concepts included social det...

The University of Arizona, Optical Sciences Center, Remote Sensing Group is involved with the vicarious calibration of satellite sensors in support of NASA’s Earth Observing System (EOS) program. Sensor calibration coefficients are calculated by comparing sensor DN values to top of the atmosphere (TOA) radiance values, calculated from radiative transfer code (RTC). The RTC output is based on me...

We present a computational model for target discrimination based on intracellular recordings from neurons in the fly visual system. Determining how insects detect and track small moving features, often against cluttered moving backgrounds, is an intriguing challenge, both from a physiological and a computational perspective. Previous research has characterized higher-order neurons within the fl...

During yeast ribosome synthesis, three early cleavages generate the 20S precursor to the 18S rRNA component of the 40S subunits. These cleavages can occur either on the nascent transcript (nascent transcript cleavage; NTC) or on the 35S pre-rRNA that has been fully transcribed and released from the rDNA (released transcript cleavage; RTC). These alternative pathways cannot be assessed by conven...

BACKGROUND AND AIMS Teledermatology is an area that has shown rapid growth in the recent past. However, not many studies have been conducted with regards to the application of teledermatology in India. Aim of our study was to evaluate the clinical profiles of cases referred for teledermatology consultation at our center, and to assess and compare the different modalities of teledermatology cons...

BACKGROUND In the last several years, research related to social determinants of health (SDH) has begun to resonate in the medical, behavioral, social and political sciences arena. The aim of the present study was to explore the relationship between SDH and depression, and to provide new evidences and clues for depression control and prevention. METHODOLOGY/PRINCIPAL FINDINGS This research wa...
