Abstract Premise Despite the availability of several plant trait databases, significant traits remain undocumented for a substantial number of species. To address this issue, the current study explored digital text from the Global Biodiversity Information Facility (GBIF) as an in...

Three-Dimensional Magnetic Alignment of Cellulose II Microcrystals for Elucidating Their Hydrogen-Bonding Network and Anisotropic Mechanical Properties

Abstract This study establishes a comprehensive platform for the axis-resolved analysis of anisotropic structure−property relationships in cellulose II. Using plate-like microcrystals synthesized via enzymatic polymerization, three-dimensionally oriented composite films were fabr...

Relationship between objective sleep efficiency and psychological distress in middle-aged and older Japanese: Results by work in the Shika study

Effects of furfurylation on white pocket rot in Japanese larch heartwood caused by Porodaedalea chrysoloma

Abstract Porodaedalea chrysoloma (Fr.) Fiasson et Niemelä is a basidiomycete that causes pitting white rot in conifer trees such as Japanese larch, leading to significant losses in wood density and mechanical strength. Consequently, the utilization of decayed wood is severely lim...

Origin of the Eleusine indica population on the active volcanic Nishinoshima Island, Japan

Nishinoshima Island, located approximately 1,000 km south of mainland Japan and 130 km from the Ogasawara Islands, emerged as a new island due to volcanic activity in 1973. On this isolated island, grasses such as Eleusine indica and Portulaca oleracea have been observed growing,...

Associations of Happiness, Ikigai, and Enjoyment of Daily Life with Frequency of Forest Walking in a Japanese General Population: The Japan Multi-Institutional Collaborative Cohort Daiko Study

A number of studies have examined the acute effects of shinrin-yoku (forest bathing), or forest walking; however, only a limited number of epidemiological studies have examined the association between habitual forest walking and daily health. The aim of this study was to examine...
