How should one define entropy production for nonequilibrium quantum spin systems? [PDF]
, 2001 This paper discusses entropy production in nonequilibrium steady states for infinite quantum spin systems. Rigorous results have been obtained recently in this area, but a physical discussion shows that some questions of principle remain to be clarified.

Mathematics as a cultural product
, 1999 In this short introduction, we report on the main points discussed in our group during the Conference, as well as some problems that appeared to be important issues for future research. One of the main issues in our group's discussion was that mathematics is a complex cultural product so we begin with that.

A Remark on the Strict Positivity of the Entropy Production [PDF]
, 2005 We establish an algebraic criterion which ensures the strict positivity of the entropy production in quantum models consisting of a small system coupled to thermal reservoirs at different temperatures.

Antibacterial Activity of Germacrane Type Sesquiterpenes from Curcuma heyneana Rhizomes
Indonesian Journal of Chemistry, 2014 The isolation of terpenoids from C. heyneana rhizomes and their antibacterial activity have been conducted. The terpenoids were isolated by using vacuum liquid chromatography and radial chromatography.

Normal Products and Zimmermann Identities in Configuration Space BPHZ Renormalization [PDF]
arXiv, 2017 The notion of normal products, a generalization of Wick products, is derived with respect to BPHZ renormalization formulated entirely in configuration space. Inserted into time-ordered products, normal products admit the limit of coinciding field operators, which constitute the product. The derivation requires the introduction of Zimmermann identities,
