Previous literature suggests that higher ambient temperature may play a role in increasing the risk of suicide. However, no multi-country study has explored shape association and moderate extreme heat across different locations.
Abstract Epidemiological analyses of health risks associated with non-optimal temperature are traditionally based on ground observations from weather stations that offer limited spatial and temporal coverage. Climate reanalysis represents an alternative option provide complete spatio-temporal exposure coverage, yet to be systematically explored for their suitability in assessing temperature-related at a global scale. Here we the first comprehensive analysis over multiple regions assess most...

This paper proposes a new approach for video stabilization. Most existing stabilization methods adopt framework of three steps, motion estimation, compensation and image composition. Camera is often estimated based on pairwise registration between frames. Thus, these assume static scenes or distant backgrounds. Furthermore, with moving objects, robust are required finding the dominant motion. Such assumptions judgements could lead to errors in parameters. Errors compounded by which smoothes...

Thumb-to-fingers interfaces augment touch widgets on fingers, which are manipulated by the thumb. Such ideal for one-handed eyes-free input since fingers enable easy access stylus This study presents DigitSpace, a thumb-to-fingers interface that addresses two ergonomic factors: hand anatomy and precision. Hand restricts possible movements of thumb, further influences physical comfort during interactions. Touch precision is human factor determines how precisely users can manipulate set...
The sensation of being able to feel the shape an object when grasping it in Virtual Reality (VR) enhances a sense presence and ease manipulation. Though most prior works focus on force feedback fingers, haptic emulation 3D requires touch using entire hand. Hence, we present Pop-up Prop Palm (PuPoP), light-weight pneumatic shape-proxy interface worn palm that pops several airbags up with predefined primitive shapes for grasping. When user's hand encounters virtual object, airbag appropriate...
Background: The association between fine particulate matter (PM 2.5 ) and mortality widely differs as well within countries. Differences in PM composition can play a role modifying the effect estimates, but there is little evidence about which components have higher impacts on mortality. Methods: We applied 2-stage analysis data collected from 210 locations 16 In first stage, we estimated location-specific relative risks (RR) for associated with daily total through time series regression...
