Approaches to case analyses in synchronous and asynchronous environments" (2008). Computer-mediated communication (CMC) tools can be used to integrate time-intensive tasks, such as case study analyses, more easily into formal learning environments. How students talk together online in CMC environments is an area that has not yet been thoroughly investigated. This paper extends findings from a p...

Cloud computing provides blockchain a flexible and cost-effective service by on-demand resource sharing, which also introduces additional security risks. Adaptive Cyber Defense (ACD) solution that continuously changes the attack surface according to cloud environments. The dynamic characteristics of ACDs give defenders tactical advantage against threats. However, when assessing effectiveness AC...

In this paper, a general framework was presented to boost heuristic optimization algorithms based on swarm intelligence from static to dynamic environments. Regarding the problems of dynamic optimization as opposed to static environments, evaluation function or constraints change in the time and hence place of optimization. The subject matter of the framework is based on the variability of the ...

Originally puzzles were not for recreation, but serious questions you might be killed if you couldn’t solve them. But in modern times, puzzles had become a sort of recreation, decreasing the seriousness and religiousness gradually. Now, the ‘rule creators’ of puzzles began to attract notice. I, as a rule creator, published a book, Kyoto University Student, Higashida’s Puzzles. I’ll show several...

BACKGROUND It has been reported that the tumor suppressor gene, PTEN, which is inactivated in many malignant tumors, plays an important role in apoptosis, cell cycle arrest, cell migration, and cell spread. For cancer gene therapy, one of the most important problems is low gene transfection efficiency. METHODS In the present study, to take full advantage of adenovirus in gene expression, we p...

his, Mrs. Lorimer, who was ill. Dr. Stuart agreed and called on the following day. He was then told to consult with Dr. Brougham regarding the patient, and accordingly made an appointment with Dr. Brougham for tho following day, which that gentleman was unable to keep. Dr. Stuart paid his second visit, however, and on the third day, the 11th July, both he and Dr. Brougham held a consultation, s...

Interest in virtual reality technologies has increased significantly recent years, and an effort is being made to integrate it into educational environments. This study aims investigate the impact of synchronous distance courses Virtual Reality (VR) learning environment (via vAcademia) Web-based Adobe Connect) on undergraduate students' motivation levels perceived sociability. The sample was co...

In connection with studies on riboflavin in various fractions of precancerous livers, the observation was made that homogenates of liver tissue from r a t s f e d m ' methylp dimethylaminoazobenzene failed to coagulate at 100 ~ C., whereas similar homogenates from normal rats coagulated completely in. 1 to 5 minutes. Accordingly a study was made of the stability towards heat of homogenates from...
