It has been found that 4-isopropyl-2,6-bis(1-phenylethyl)phenol (KTH-13), a novel compound isolated from Cordyceps bassiana, is able to suppress tumor cell proliferation by inducing apoptosis. To mass-produce this compound, we established a total synthesis method. Using those conditions, we further synthesized various analogs with structural similarity to KTH-13. In this study, we aimed to test...

In this paper, we initiate the notion of k^{th} order slant Hankel operators on L^2(T^n) for k greater than or equal to 2 and n 1 where T^n denotes n-torus. We give necessary sufficient condition a bounded operator be discuss their commutative, compactness, hyponormal isometric property.

In this paper, we study the kth upper bases of primitive non-powerful signed digraphs. A bound on the kth upper bases of all primitive non-powerful signed digraphs is obtained, and the equality case of the bound is characterized. We also show that there exists “gap” in the kth upper base set of primitive non-powerful signed digraphs. AMS classification: 05C20, 05C50, 15A48

The study was inspired by the need to assess long-term metal retention in municipal solid waste (MSW) landfills. The long-term processes in landfills are poorly known due to the relatively short time that such landfills have been in existence. Natural analogues where similar metal binding processes could be expected were therefore sought for. The work described in this thesis aims to elucidate ...

Nonhomomorphicity is a new nonlinearity characterization of a mapping or S box An important advantage of nonhomomorphicity over other criteria is that it is easy to estimate by a fast statistical method with a high reliability due to the Law of Large Numbers In this paper we explicitly express the kth order nonhomomorphicity of S boxes by other criteria identify the tight upper and lower bounds...

this study compares differences between japan and austria as regarding outdoor activities. we conducted a survey with respect to the utility patterns of kairakuen garden in mito city, ibaraki prefecture, which is one of the three major historical gardens in japan noted for its beauty. this paper compares the results of our survey with a study of the recreational and spatial utility of the hist...

Sufficient dimension reduction aims at finding transformations of predictor X without losing any regression information of Y versus X . If we are only interested in the information contained in the mean function or the kth moment function of Y given X , estimation of the central mean space or the central kth moment space becomes our focus. However, existing estimators for the central mean space...
