Introduction of spin-orbit interaction into graphene with hydrogenation

Introduction of spin-orbit interaction (SOI) into graphene with weak hydrogenation ($\sim$0.1\%) by dissociation of hydrogen silsesquioxane resist has been confirmed through the appearance of inverse spin Hall effect. The spin current was produced by spin injection from permalloy electrodes excluding non-spin relating experimental artifact.Comment: Short not

Day-to-day experiences of amae in Japanese romantic relationships

This is the post-print version of the Article. The official published version can be accessed from the link below - Copyright @ 2011 Wiley-BlackwellThe cultural psychology of romantic relationships is relatively understudied. To redress this lacunae, the present study examined the Japanese concept of 'amae', or the state of expecting a close other's indulgence when one behaves inappropriately, within the day-to-day relationships of 30 Japanese undergraduate romantic couples. For 2 weeks, both partners completed daily diaries that assessed their amae behaviour (requesting, receiving, and providing amae), relationship quality, conflict, and motivation to enhance closeness. Results revealed that amae behaviour was associated with greater relationship quality and less conflict. The motivation to enhance closeness partially mediated the association of amae with relationship quality

An Implementable Version of the Sturm's Algorithm for the Number of Zeros of a Real Polynomial

An algorithm is considered to give the number of real zeros of a real polynomial on an interval rather than their precise locations. The Sturm's algorithm is suitable for such problems because it is not uncommon that the polynomial to be treated is in fact over the rational field Q. While the algorithm is implemented through a symbolic and algebraic manipulation (SAM) software on a computer, computational costs make a significant increase as the degree of polynomial increases. The reason lies in the time-consuming reduction of non-reduced fraction to the irreducible one in SAM. The essential information in the Sturm's algorithm is however not the coefficients of polynomials in the Sturm sequence but their signs at point in the interval. From this viewpoint we have reached an improved version of the algorithm, which drastically reduces the costs in comparison with the original Sturm's algorithm. Some numerical examples arising from a problem in mathematics will be shown.departmental bulletin pape

The double bind of triple jeopardy : exploring the impact of multiple minority stress on LGBTQ-identified Asian women in America

This study was undertaken to determine the impact of multiple minority stress on LGBTQ-identified Asian women living in America. The research explored how the values of families of origin, communities, and chosen families impact identity negotiations, as well as overall quality of life. The findings of this study were utilized to conceptualize best practices for mental health practitioners around better meeting the needs of individuals experiencing multiple minority stress. One hundred and fifty-two women living in the United States responded to a series of multiple choice and narrative response questions via Internet survey. They were asked questions focusing on demographics, family of origin, Asian community/ies, LGBTQ community/ies, and chosen families. Participants were also asked to fill out responses to the Comprehensive Quality of Life Scale – Adult (ComQol-A5). Results demonstrated that LGBTQ-identified Asian women in America struggle to find communities that are accepting of their multiple, intersecting social identities, as experiences of stigmatization and invisibility were common. Distinct themes in the experienced racism and heterosexism within families of origin, Asian and LGBTQ communities were documented, as were the strengths present in chosen family structures. These strengths were explored as learning tools for the development of best practices in the treatment of multiple minority stress

Embedding Bifurcations into Pneumatic Artificial Muscle

計算する人工筋肉～物理リザバー計算により分岐構造を含む多様なパターンを生成～ 京都大学プレスリリース. 2024-04-25.Built-in bionic computing: Artificial muscles with embedded bifurcation structures can control complex motion. 京都大学プレスリリース. 2024-04-26Harnessing complex body dynamics has long been a challenge in robotics, particularly when dealing with soft dynamics, which exhibit high complexity in interacting with the environment. Recent studies indicate that these dynamics can be used as a computational resource, exemplified by the McKibben pneumatic artificial muscle, a common soft actuator. This study demonstrates that bifurcations, including periodic and chaotic dynamics, can be embedded into the pneumatic artificial muscle, with the entire bifurcation structure using the framework of physical reservoir computing. These results suggest that dynamics not present in training data can be embedded through bifurcation embedment, implying the capability to incorporate various qualitatively different patterns into pneumatic artificial muscle without the need to design and learn all required patterns explicitly. Thus, this study introduces a novel approach to simplify robotic devices and control training by reducing reliance on external pattern generators and the amount and types of training data needed for control

Purification and characterization of a [3Fe-4S] [4Fe-4S] type ferredoxin from hyperthermophilic archaeon, Pyrobaculum islandicum

金沢大学理工研究域自然システム学系A ferredoxin was purfied from the hyperthermophilic archaeon, Pyrobaculum islandicum. EPR spectra and metal content analyses suggested that the ferredoxin molecule contained one [3Fe-4S] and one [4Fe-4S] cluster. The ferredoxin was rapidly reduced by 8-oxoglutarate: ferredoxin oxidoreductase purfied from P. islandicum, indicating that it functions physiologically as an electron sink for the redox enzymes participating in glycolytic metabolism. Furthermore, the amino acid sequence of the P. islandicum ferredoxin was compared with those of several other bacterial ferredoxins
