Euler Product Expressions of Absolute Tensor Products of Dirichlet L-Functions

引用

Advances in Pure Mathematics 2024年第6期14卷 451-486页

作者： Hidenori Tanaka shin-ya Koyama Department of Biomedical Engineering Toyo University Saitama Japan Department of Mechanical Engineering Toyo University Saitama Japan

In this paper, we calculate the absolute tensor square of the Dirichlet L-functions and show that it is expressed as an Euler product over pairs of primes. The method is to construct an equation to link primes to a series which has the factors of the absolute tensor product of the Dirichlet L-functions. This study is a generalization of Akatsuka’s theorem on the Riemann zeta function, and gives a proof of Kurokawa’s prediction proposed in 1992.

A commercial Al-Mg alloy was subjected to equal channel angular pressing of 4 passes with and without postrolling, and the effects of post-rolling on the deformation characteristics of the alloy at 723 K were examined. Post-rolling was found to influence the deformation behavior significantly. The deformation behavior of the alloy processed only by equal channel angular pressing was characterized by (a) localized deformation indicated by severe surface prominence and depression, (b) the strain rate sensitivity of 0.33, and (c) moderate high strain rate superplastic elongations. By contrast, that of the alloy processed by equal channel angular pressing and post-rolling (70 % thickness reduction) was manifested by (a) uniform deformation associated with grain boundary sliding throughout the sample, (b) a sigmoidal behavior showing the strain rate sensitivity of 0.45 at the intermediate strain rates in the logarithmic stress-strain rate curve, and (c) very large high strain rate superplastic elongations.

AIM:To evaluate the treatment options for nephrotoxicity due to cisplatin combination ***:We retrospectively reviewed patients who had received cisplatin combination chemotherapy for gastric cancer between January 2002 and December *** investigated patients who had shown acute renal failure(ARF),and examined their clinical characteristics,laboratory data,use of preventive measures,treatment cycles,the amount of cisplatin administered,recovery period,subsequent treatments,and renal status between the recovered and unrecovered ***:Forty-one of the 552 patients had serum creatinine(SCR)levels greater than 1.5 mg/*** found that pre-ARF SCR,ARF SCR,and ARF glomerular filtration rates were significantly associated with renal status postARF between the two groups(P=0.008,0.026,0.026,respectively).On the receiver operating characteristic curve of these values,a 1.75 mg/dL ARF SCR value had 87.5%sensitivity and 84.8%specificity(P=0.011).CONCLUSION:Cessation or reduction of chemotherapy should be considered for patients who have an elevation of SCR levels during cisplatin combination chemotherapy.
