Two Modes of Reflection: How Temporal, Spatial, and Social Distances Affect Reflective Writing in Family Caregiving

Therapeutic writing offers significant benefits for well-being; however, for family caregivers, conventional fixed or user-initiated schedules often fail to align with their dynamic, high-stress reality. We conducted a three-week field study with 47 caregivers using a chatbot tha...

The Dynamics of Quantumness in the Bloch Channels with the Indefinite Causal Order

The dynamics of single-qubit coherence and two-qubit entanglement are investigated in the Bloch channels with the indefinite causal order, which is created by means of a quantum switch. Coherence and entanglement are quantified respectively in terms of l 1 -norm and negativity. I...

Development and validation of the Japanese version of the psychological preparedness for disaster threat scale

Abstract Background Japan is highly vulnerable to hydro-meteorological hazards such as typhoons, severe storms, and flooding, which cause recurring damage to life and property. Consequently, there is a need for a culturally adapted tool to assess individuals’ psychological readin...

Development of a psychological preparedness scale for elementary school students (C-PPDTS) and a preliminary evaluation of a disaster education program

Abstract Background Disaster risk reduction (DRR) education is essential to protecting children from increasingly severe hydrometeorological events. Traditional DRR education often relies on fear appeals that can induce overwhelming anxiety in children. Psychological preparedness...

REAP1/AtSWAP70 integrates RAB5 and ROP signalling during sexual reproduction

Small GTPases of the Ras superfamily are critical regulators of diverse cellular processes. While crosstalk between their signalling pathways has been documented in animals, similar mechanisms remain unexplored in plants, where small GTPases have undergone unique evolutionary div...

Leveraging the salivary microbiome profile to stratify REM sleep behavior disorder and synucleinopathies

Abstract Few studies have explored noninvasive biomarkers of synucleinopathies, including Parkinson’s disease (PD), and rapid-eye-movement behavior disorder (RBD), a prodromal stage for these conditions. Human oral/salivary microbiomes are altered in PD, highlighting their potent...

A visual analysis tool for checking volleyball serve form

Abstract This paper proposes a system that integrates a series of visualization components to observe the process of serve practice. This study supposes to ask the players to repeatedly hit the serve toward a target object, and the user of the system measures the distance between...

Validation and Reliability Assessment of the Japanese Version of the Salzburg Stress Eating Scale in an Adult Population

Abstract Recent studies have explored the impact of stress on eating behavior, necessitating a clear understanding of eating patterns during periods of heightened stress. They revealed that individuals either increased, decreased, or maintained an unchanged food intake under stre...

Derivation of human post-mitotic cardiomyocytes from tetraploid iPSCs

Human induced pluripotent stem cell (iPSC)-derived cardiomyocytes (iPS-CMs) have great potential in regenerative medicine. However, iPS-CMs are immature and resemble fetal cardiomyocytes, restricting their application. Fetal cardiomyocytes in the human heart are diploid and proli...
