Long-term underwater camera surveillance for monitoring and analysis of fish populations

Long-term monitoring of the underwater environment is still labour intensive work. Using underwater surveillance cameras to monitor this environment has the potential advantage to make the task become less labour intensive. Also, the obtained data can be stored making the research reproducible. In this work, a system to analyse long-term underwater camera footage (more than 3 years of 12 hours a day underwater camera footage from 10 cameras) is described. This system uses video processing software to detect and recognise fish species. This footage is processed on supercomputers, which allow marine biologists to request automatic processing on these videos and afterwards analyse the results using a web-interface that allows them to display counts of fish species in the camera footage

Traditional beliefs and practices in the postpartum period in Fujian Province, China: a qualitative study

<p>Abstract</p> <p>Background</p> <p><it>Zuo yuezi </it>is the month postpartum in China associated with a variety of traditional beliefs and practices. We explored the current status of <it>zuo yuezi </it>from social, cultural and western medical perspectives.</p> <p>Methods</p> <p>We interviewed family members (36) and health workers (8) in Fujian Province, selecting one rural and one rapidly developing urban county. We asked about their traditional beliefs and their behaviour postpartum. We used a framework approach to identify main themes. We categorised reported behaviour against their probable effects on health, drawing on Western standards.</p> <p>Results</p> <p>Respondents reported that <it>zuo yuezi </it>was commonly practiced in urban and rural families to help the mother regain her strength and protect her future health. <it>Zuo yuezi </it>included: dietary precautions, such as eating more food and avoiding cold food; behavioural precautions, such as staying inside the home, avoiding housework and limiting visitors; hygiene precautions, such as restricting bathing and dental hygiene; and practices associated with infant feeding, including supplementary feeding and giving honeysuckle herb to the infant. Respondents reported that the main reasons for adhering to these practices were respect for tradition, and following the advice of elders. Categorised against Western medical standards, several <it>zuo yuezi </it>practices are beneficial, including eating more, eating protein rich food, avoiding housework, and daily vulval and perineal hygiene. A few are potentially harmful, including giving honeysuckle herb, and avoiding dental hygiene. Some women reported giving infants supplementary feeds, although <it>zuo yuezi </it>emphasises breast feeding.</p> <p>Conclusion</p> <p><it>Zuo yuezi </it>is an important ritual in Fujian. In medical terms, most practices are beneficial, and could be used by health staff to promote health in this period. Further research on reported potentially harmful practices, such as supplements to breast feeding, is needed.</p

Gate Leakage Current Reduction in Two-Step Processed High-k Dielectrics for Low Power Applications

Reduction of the gate leakage current in nMOS high-k devices is demonstrated by an engineered two-step deposited Hf-based high-k dielectric film. The electrical characteristics and reliability of the devices fabricated using the proposed two-step and conventional one-step high-k gate stacks are shown to be comparable. The lower leakage current is attributed to the misalignment of the grain boundaries in the multi-layer high-k dielectrics

A Novel Fluorine Incorporated Band Engineered (BE) Tunnel (SiO2/ HfSiO/ SiO2) TANOS with Excellent Program/Erase & Endurance to 10^5 Cycles

We demonstrate for the first time a fluorine incorporated band- engineered (BE) tunnel oxide (SiO2/HfSiO/SiO2) TANOS with excellent program / erase (P/E) characteristics and endurance to 105 cycles. Incorporating fluorine in the tunnel dielectric improves Si/SiO2 interface resulting in excellent endurance of nearly constant over 3 V P/E window for at least 105 cycles. Fluorine also reduces interface state generation during retention by ~20%. Furthermore, Fluorine passivates bulk traps leading to as much as ~10times higher charge to breakdown (Qbd) and ~10-50times lower interface state density (Dit). Fluorine passivation for BE-TANOS is significant because it improves reliability assisting implementation of TANOS flash NVM beyond the 20 nm node
