Soka University is a private university in Hachiōji, Tokyo, Japan. The school was founded in 1969 and opened to undergraduate students in 1971 and opened a graduate school in 1975.Soka University of America is a related school located in Aliso Viejo, California and offers both graduate and undergraduate degrees. It was founded in 2001. Wikipedia.

In ideal proteins, only native interactions are stabilized step-by-step in a smooth funnel-like energy landscape. In real proteins, however, the transient formation of non-native structures is frequently observed. In this review, the transient formation of non-native structures is described using the non-native helix formation during the folding of β-lactoglobulin as a prominent example. Although β-lactoglobulin is a predominantly β-sheet protein, it has been shown to form non-native helices during the early stage of folding. The location of non-native helices, their stabilization mechanism, and their role in the folding reaction are discussed. Source

This article examines the reducing and recycling effects caused by municipal solid waste policies, such as garbage pricing and recyclables collection. Equations for garbage and recyclables are estimated using Heckman’s two-step estimation and seemingly unrelated regression (SUR) to consider sample selection bias and the correlation between garbage and recyclables emission. The estimation results suggest that municipal PET bottle collection leads to a reduction in the amount of garbage collected. Furthermore, the results reveal that garbage pricing increases the quantity of PET bottles collected, while it decreases the amount of garbage. © 2007, Springer Japan. Source

Many databases of carbohydrate structures and related information can be found on the World Wide Web. This review covers the major carbohydrate databases that have potential utility for glycoscientists and researchers entering the glycosciences. The first half provides a brief overview of carbohydrate databases and web resources (including a history of carbohydrate databases and carbohydrate notations used in these databases), and the second half provides a guide that can be used as an index to determine which resources provide the data of most interest to the user. © 2013 by The American Society for Biochemistry and Molecular Biology, Inc.

Which risk should one choose when facing alternatives with different levels of risk?We discuss here adaptive processes in such risk choice behavior by generalizing the study of Roos et al. [2010].We deal with an n-choice game in which every player sequentially chooses n times of lotteries of which there are two types: a safe lottery and a risky lottery. We analyze this model in more detail by elaborating the game. Based on the results of mathematical analysis, replicator dynamics analysis, and numerical simulations, we derived some salient features of risk choice behavior. We show that all the risk strategies can be divided into two groups: persistence and nonpersistence. We also proved that the dynamics with perturbation in which a mutation is installed is globally asymptotically stable to a unique equilibrium point for any initial population. The numerical simulations clarify that the number of persistent strategies seldom increases regardless of the increase in n, and suggest that a rarity of dominant choice strategies is widely observed in many social contexts. These facts not only go hand-in-hand with some well-known insights from prospect theory, but may also provide some theoretical hypotheses for various fields such as behavioral economics, ecology, sociology, and consumer behavioral theory. © 2013 ACM.

This chapter describes the Glycan Miner Tool, which is available as a part of the Resource for INformatics of Glycomes at Soka Web site. It implements the α-closed frequent subtree algorithm to find significant subtrees from within a data set of glycan structures, or carbohydrate sugar chains. The results are returned in order of p-value, which is computed based on the probability of the reproducibility of the returned structures. There is also a user-friendly manual that allows users to apply glycan array data from the Consortium for Functional Glycomics. Thus, glycobiologists can take the glycan structures that bind to a particular glycan-binding protein, for example, to retrieve the glycan subtrees that are deemed to be important for the binding to occur. © 2013 Springer Science+Business Media New York.
