The detailed mechanisms that lowered the atmospheric CO2 concentrations by approximately 100 ppm during glacial periods remain a crucial open question. It is hypothesized that increased ocean alkalini [...]

Allylic amines are ubiquitous, prevalent in various biologically active compounds, and essential as synthetic intermediates for many organic compounds. We reported the first direct catalytic amination [...]

Recent advances in UAV LiDAR and airborne laser scanning have enabled high-resolution and low-cost acquisition of three-dimensional forest point cloud data. At the same time, analysis methods such as [...]

Palladium hydrides exhibit superconductivity at hydrogen concentrations above 0.8. The role of hydrogen atoms in the mechanism of hydride superconductivity will be clarified by microscopic measurement [...]

Development of a High-Accuracy Predictive Framework for Soil–Machine Interaction under Repeated Loading Using Non-Classical Plasticity and Machine Learning

Department of Agro-environmental Sciences, Graduate School of Bioresource and Bioenvironmental Sciences

This research aims to develop a new DEM contact model capable of reproducing cumulative plastic deformation and stiffness evolution under repeated loading, limitations that conventional models cannot [...]

As aging progresses, the deterioration of biological functions and homeostasis leads to a decrease in survival rate along with an increased risk of various diseases. Anti-aging research for extending [...]

コンクリートの劣化の一つであるアルカリシリカ反応（ASR）は，コンクリートの材料間の反応に由来し，致命的な膨張ひび割れを引き起こす。コンクリートごとに使用されるセメント・石・砂やその配調合が異なるため，ASRには画一的な対策が通用しない。そこで，各要因の影響度を把握するための膨張実験と，劣化メカニズム解明に向けた微視的観察を行い，数値的な予測モデルを提案することで，新たなインフラ設計・維持管理手法 [...]

In recent years, the loss of understory vegetation such as dwarf bamboo (Sasa spp.) has become more serious due to overgrazing by Sika deer, which is rapidly increasing in population. Degradation of [...]
