Differential Equations and Representation Theory : Proceedings of JMM Workshop on Differential Equations and Representation Theory Festschrift in Honor of Toshio Oshima, December 26-27, 2018 Josai University
We present a bialternant formula for odd symplectic characters, which are the characters of indecomposable modules of odd symplectic groups introduced by R. Proctor. As an application, we give a linear algebraic proof to an odd symplectic character identity due to R. P. Brent, C. Krattenthaler and S. O. Warnaar

We give a characterization of the monodromy group of the second order linear Fuchsian differential equation on the Riemann sphere which has three singular points
Re-Attempting Eradication : The Increasing Drug Problem in China
1953 年に世界に向けて麻薬撲滅を宣言した中国において、深刻な薬物問題が発生している。薬物との決別を宣言した中国において、なぜふたたび薬物犯罪が横行しているのか。本稿では先ず、中国が新政府成立初期から展開してきたアヘンなどの麻薬撲滅に向けた取り組みを跡づけていく。同時に、中国で薬物が蔓延している背景についても探り、薬物犯罪への中国の姿勢、ならびに薬物防止に向けた対策についても検証する。結果として、中国において、ふたたび薬物問題が浮上し蔓延するようになったのは、国内のみならず周辺国からの流入が影響していることがみえてきた。特に、国境を面する地域に「黄金の三角地帯」や「黄金の三日月地帯」など、世界でも有数の薬物生産・栽培地が控えていることは、中国の薬物問題をより複雑にしているといえるだろう。薬物犯罪の取り締まりについては、“War on Drugs”(薬物戦争)の行き詰まりを受けて、各国が薬物政策の見直しを迫られるなか、中国は制
度を整備し、厳罰化を強化する姿勢を示している。一方で、薬物使用者については、治療の対象とみなして、新たに導入した地域での依存治療を軸に調整をはかろうとしていることも見えてきた。薬物の防止に向けては、新型薬物の広がりや、低年齢化、形を変えた売買などが盛んになっている状況を踏まえ、現況の薬物防止教育の見直しを模索する動きが出ていることも明らかにした。In 1953, China declared to the world that it had eradicated the use of opiates and other narcotics However, drug use has once again become widespread. What is the causes of his?In this article, the author explains the process of China’s efforts to enforce the eradication of drugs such as opium, since the Communist Party of China (CCP) came to power and measures that are being taken to prevent the use and spread of illegal drugs within the country.It was found that the drug problem resurfaced and spread in China, even after it declared they were eradicated 1953. This was mainly due to an influx of from neighboring countries, in particular from the world’s leading drug production and cultivation areas such as the Golden Triangle and Golden Crescent, both which border China. In response, the CCP introduced harsher penalties to stem the flow of drugs, and strengthened existing the system of severe punishment. Meanwhile, other countries began reviewing
drug policy due to a deadlock on the war against drugs.論
Effect of Hydrophilic Chain Length in Non-Ionic Surfactant on the Physicochemical Characteristics, Gene Expression Efficiency and Cytotoxicity of DNA/Poly-L-Ornithine/Niosome Ternary Complexes for Gene Delivery
The aim of this study is to clarify the effect of hydrophilic ethylene oxide (EO) chain length in steareths on the physicochemical characteristics, gene expression efficiency and cytotoxicity of plasmid DNA (pDNA)/poly-L-ornithine (PLO)/niosomes (consisting of non-ionic surfactants [NISs], polyoxyethylene stearyl ethers [steareths]) ternary complexes. Niosomes were prepared with NISs, a series of steareth (steareth-2, steareth-5 and steareth-20) or Tween 80, cholesterol, and octadecylamine of cationic lipid, followed by complexing with pDNA encoding luciferase gene and PLO. The physicochemical characteristics, gene expression efficiency and cytotoxicity of the prepared pDNA/PLO/niosome ternary complexes were evaluated. The particle size and ζ potential of steareth niosomes and pDNA/PLO/steareth niosome ternary complexes decreased with lengthening of the EO chain in steareth. All complexes showed a high pDNA condensation ability, and pDNA/PLO/steareth-2 niosome ternary complexes possessed the highest protective effect in the presence of polyanion, dextran sulfate. The transfection efficiency and cell viability of pDNA/PLO/steareth niosome ternary complexes also decreased with the lengthening of the EO chain. Among the pDNA/PLO/niosome ternary complexes, the pDNA/PLO/steareth-2 niosome ternary complexes showed the highest transfection efficiency and almost no cell damage. In conclusion, it was suggested that the EO chain length in steareths affects the physicochemical characteristics, gene expression efficiency and cytotoxicity of pDNA/PLO/steareth niosome ternary complexes. Furthermore, we pointed out that the pDNA/PLO/steareth-2 niosome ternary complexes might deliver genes efficiently and safely. Further study is required to more elevate the transfection efficiency, stability and safety of pDNA/PLO/steareth-2 niosome ternary complexes, such as using target compounds.2021年1月8⽇付にて日本薬剤学会より使用許諾取得済

Copper-Mediated Cascade Synthesis of Open-Cage Fullerenes
An open-cage fullerene bearing an eight-membered ring orifice has been synthesized in one pot by the reaction of C60 with propargylic phosphate in the presence of CuCl. The reaction cascade involves the transformation of the phosphate to the 1,3-dienyl phosphate, which enables the reaction with C60 by [4 + 2] cycloaddition to form the cyclohexene-annulated intermediate, and subsequent intramolecular syn-elimination of the phosphodiester affords the cyclohexadiene-annulated fullerene derivative as the precursor for the open-cage fullerene.Published: April 21, 202
Program cording using software Python -Report on workshop and seminar-
IoTの普及などにより,今後ますますIT技術のニーズは高まっていくと考えられる。そこで,近年注目されているプログラミング言語“Python”によるコード実装の内容を報告する。城西大学理学部数学科が主催している,高校生向け応用数学体験講座の講演内容と,数学科の学生が行ったアクティブラーニングの内容について,実際に作成したコードを紹介する。公開講座のアンケート結果から,統計的プログラミングへの関心が高いことが判明した。今後はPythonを取り入れた授業を展開することで,データサイエンスのスキルがある人材の育成が期待できる。研究ノー
