It affects the macula region of the retina leading to severe vision loss and legal blindness in individuals 〉 50 years of age （Wong et al., 2014）. The precise aetiology of AMD is unknown but smoking, age and genetic factors are major risk factors for AMD predisposition （Ding et al., 2009）. The genetic basis of AMD is well described with a recent study from the International AMD gene consortium （IAMDGC） reporting 52 genetic variants across 34 loci associated with the risk of AMD pathogenesis and explaining more than 50% of the genetic heritabilitv of the disease （Fritsche et al., 2016）.展开更多

While advancing therapies may add significant longevity, they also bring about new end-of-life decision-making challenges for patients and their families who also must weigh the advan- tages of reduced mortality to the possibility of longer lives consisting of high morbidity, frailty, pain, and poor quality of living. Advance care entails options of withholding or withdrawing therapies, and has become a familiar part of cardiovascular care for older patients in Western countries. However, as advanced cardiovascular practices extend to developing countries, the interrelated concept of advance care is rarely straight forward as it is affected by local cultural traditions and mores, and can lead to very different inferences and use. This paper discusses the concepts of advance care planning, surrogate decision-making, orders for resuscitation and futility in patients with cardiac dis- ease with comparisons of West to East, focusing particularly on the United States versus India.展开更多

The thermal wind sensor chip is fabricated by metal lift-off processes on the ceramic substrate. An advanced direct chip attaching （DCA） packaging is adopted and this new packaged method simplifies the processes of packaging further. Simulations of the advanced DCA packaged sensor based on computational fluid dynamics （CFD） model show the sensor can detect wind speed and direction effectively. The wind tunnel testing results show the advanced DCA packaged sensor can detect the wind direction from 0° to 360° and wind speed from 0 to 20 m/s with the error less than 0.5 m/s. The nonlinear fitting based least square method in Matlab is used to analyze the performance of the sensor.展开更多
