Enhanced Thermal Electromotive Force in Lithiated CoPBA/NiPBA Tertiary Battery

Tertiary batteries (TBs), or thermo-rechargeable batteries, have attracted attention as an energy harvesting technology that utilizes changes in ambient temperature. Prussian blue analogues (A-MPBAs; AxM[Fe(CN)6]y, where A and M are Li+ or Na+ ions and a transition metal, respect...

Rapid genome-wide purging following tsunami-induced hybridization in a stickleback population

Speciation is the process by which barriers to gene flow evolve between populations. As speciation approaches completion, genome-wide divergence can be maintained in the face of hybridization. Because real-time observations of genomic changes following hybridization in natural po...

Development of a polyclonal antibody-based sandwich ELISpot assay for interleukin-4/13B1 in rainbow trout Oncorhynchus mykiss

Abstract In mammals, interleukin-4 (IL-4) and IL-13 are important Th2 cytokines that enhance antibody production by B cells and proliferation of Th2 cells. Salmonid fish have three homologs to both of these cytokines as a result of four rounds of whole genome duplication events,...

The recovery paradox: integrating symptom, restoration, and lifeworld evidence for long-term disaster recovery management

Purpose This paper reconsiders long-term disaster recovery assessment by distinguishing declining psychological symptoms, visible restoration of housing and services, and the recovery of everyday roles, relationships, routines, place relations, and future possibilities through wh...

Development of an urban typology framework for supporting sustainable freight planning: A case of Japanese municipalities

As the logistics environment changes dramatically in cities around the world, various freight-related issues have emerged. To address these issues, responses from the public sector are becoming increasingly important, especially at the local government level. However, knowledge a...

Microdroplet-based high-throughput screening for antagonistic bacteria targeting penaeid shrimp pathogenic Vibrio harveyi

Antagonistic bacteria that suppress the growth of specific bacteria have attracted attention as an antibiotics-independent strategy for infectious disease control in aquaculture. Microfluidics-based water-in-oil droplets (microdroplets) enable high-throughput screening of antagon...

Feasibility to detect rapid change and disappearance of seagrass: Lessons from nearly 80 years of vegetation change in the Ako, Seto Inland Sea, Japan

Abstract. Seagrass meadows provide essential ecosystem services but are declining globally, creating an urgent need for continuous monitoring and management. However, the high cost of commercial satellite imagery and field surveys limits sustained observation, highlighting the ne...

Dietary supplementation with phlorotannin-lowered Eisenia nipponica increases caecal antioxidant activity and promotes Akkermansia in mice

Eisenia nipponica (EN), a traditional Japanese edible brown alga, is rich in storage polysaccharides (laminaran) and polyphenols (phlorotannins) during summer. Laminaran is a water-soluble dietary fibre readily fermented in the gut, whereas the phlorotannins in EN exhibit potent...

Integrating field observations and rearing experiments reveals limited temperature sensitiveness of sex determination in the bearded silverside Atherion elymus

Abstract Water temperature is a key environmental factor shaping sex determination in many gonochoristic fishes, with direct consequences for population responses to climate warming. This study is the first examination of temperature effects on sex determination in an atherionid...
