Nearly a quarter of Canada’s landmass is covered by mountainous terrain,making mountains an important aspect of the physical and human geography of the *** areas in Canada have motivated a great deal of research activity,yet the state of mountain research in the country has never been systematically characterized,precluding a detailed understanding of what is being studied,when,where,how,and by *** response,we conducted a systematic scoping review to rigorously identify,collate,and critically examine existing peer-reviewed articles related to mountains in Canada.2,888 articles were included in our review,which reveals strong biases towards work in the natural sciences and in the mountain west,with little work to date in the social and health sciences or in other mountainous regions of the *** results demonstrate that Canada is among the most productive contributors to mountain research globally,but that topical and geographical biases in existing research effort leave important gaps that must be addressed to successfully navigate challenges and opportunities facing mountain areas in *** provide a roadmap to guide future mountain-focused research activities in the country.

It is intuitive that allowing a deeper search into a game tree will result in a superior player to one that is restricted in the depth of the search that it is allowed to make. Of course, searching deeper into the tree comes at increased computational cost and this is one of the trade-offs that has to be considered in developing a tree-based search algorithm. There has been some discussion as to whether the evaluation function, or the depth of the search, is the main contributory factor in the performance of an evolved checkers player. Some previous research has investigated this question （on Chess and Othello）, with differing conclusions. This suggests that different games have different emphases, with respect to these two factors. This paper provides the evidence for evolutionary checkers, and shows that the look-ahead depth （like Chess, perhaps unsurprisingly） is important. This is the first time that such an intensive study has been carried out for evolutionary checkers and given the evidence provided for Chess and Othello this is an important study that provides the evidence for another game. We arrived at our conclusion by evolving various checkers players at different ply depths and by playing them against one another, again at different ply depths. This was combined with the two-move ballot （enabling more games against the evolved players to take place） which provides strong evidence that depth of the look-ahead is important for evolved checkers players.

This paper presents a way to measure the true temperature of the electronic devices without disturbing their normal operating conditions, which involved with estimating target emissivity, background temperature correctly and choosing infrared transparent material and its transmission estimation. The temperature distributions of the main board in personal computer were measured by the method presented here with infrared thermography in several different running conditions. The measurement errors and their possible remedies are also discussed.
