Hokkaido University , or Hokudai , is one of the national universities of Japan. It is a member of the National Seven Universities, which were established as the best national higher education or research institute. It is located in downtown Sapporo, just north of Sapporo Station, and stretching approximately 2.4 kilometers northward. It is considered as one of the top universities in Japan. Wikipedia.

Although the history of photocatalysis research is not so long, many researchers have studied photocatalysis and a large number of papers on photocatalysis have been published. The objectives of this review paper are to revisit the fundamentals of photocatalysis, especially its thermodynamics and kinetics, which have not been reexamined in recent studies, to clarify the problems, if any, that prevent developments in the field of photocatalysis, and to present insights for future progress.

Emerging clinical evidence shows that the deregulation of ubiquitin-mediated degradation of oncogene products or tumour suppressors is likely to be involved in the aetiology of carcinomas and leukaemias. Recent studies have indicated that some members of the tripartite motif (TRIM) proteins (one of the subfamilies of the RING type E3 ubiquitin ligases) function as important regulators for carcinogenesis. This Review focuses on TRIM proteins that are involved in tumour development and progression. © 2011 Macmillan Publishers Limited. All rights reserved.

Tools for chemists: The Nobel Prize in Chemie 2010 was awarded for research on palladium-catalyzed cross-coupling in organic synthesis. Two of the Laureates, A. Suzuki and E. Negishi, report here first hand on the historical development and the current status of this research. Copyright © 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

Chaotic itinerancy is an autonomously excited trajectory through high-dimensional state space of cortical neural activity that causes the appearance of a temporal sequence of quasi-attractors. A quasi-attractor is a local region of weakly convergent flows that represent ordered activity, yet connected to divergent flows representing disordered, chaotic activity between the regions. In a cognitive neurodynamic aspect, quasi-attractors represent perceptions, thoughts and memories, chaotic trajectories between them with intelligent searches, such as history-dependent trial-and-error via exploration, and itinerancy with history-dependent sequences in thinking, speaking and writing. © 2014 Elsevier Ltd.
