We prove that if Cay▫$(G; S)$▫ is a connected Cayley graph with ▫$n$▫ vertices, and the prime factorization of ▫$n$▫ is very small, then Cay▫$(G; S)$▫ has a hamiltonian cycle. More precisely, if ▫$p$▫, ▫$q$▫, and ▫$r$▫ are distinct primes, then ▫$n$▫ can be of the form kp with ▫$24 \ne k < 32$▫, or ...

The principles of robotics and control are widely taught in engineering subjects, however a common problem concerns the limited availability of expensive equipment with which students can work with, in order to acquire valuable practical "hands on" experience. The MuMaTE virtual robotics and control ...

Plasmaženhanced chemical vapor deposition (PECVD) has been used to groww homo- polymerized films, co-polymerized films, and multi-layered films on a variety of substrates. The use of polymers as linear optical materials has growing, and organic materials offer several advantages over inorganic mater ...

Purpose of Review Forests support most global terrestrial biodiversity and contribute to the livelihood of billions of people, but these and other benefits are in jeopardy due to global change. This leads to questions, such as how to address the challenges of global change in forest management, give ...
