Repeated Copulation and Guarding, and Their Relationship With Male and Female Morphological Traits in the Water Scorpion .

Insects copulate multiple times not only with different mates but also with the same mate, which is called repeated copulation. It occurs as a repeated alternation between copulation and mate-guarding, leading to the prolonged physical attachment between males and females. Particularly, in species where males forcefully grasp females, attempt to mate without courtship and exhibit repeated copulations, male and female morphological traits are expected to be associated with mating characteristics.

Age-Related Plasticity Integration in Male Cicadas : Are Adult Cicadas Capital Breeders?

Labile traits, such as behavioural, physiological traits or body mass, vary within an individual either over time or across environments. Such changes within an individual can be linked across traits, forming within-individual trait correlations. These correlations are particularly expected when ageing causes changes in the expression of multiple traits.

Telemedicine-medical "snack community"-PHS ecosystem: Insights into the double-edged sword role of telemedicine in clinical practice and medical education during the COVID-19 pandemic and beyond.

Telemedicine has gained tremendous development during the COVID-19 pandemic. With deblocking and opening, telemedicine accelerates the evolvution of the medical "snack community" and undermines the perception of medical students and staff, which promotes the incidence of psychosocial-related disorders. Moreover, the inconsistent telemedicine adaptability between medical workers and patients aggravates the doctor-patient conflict due to the aging population and COVID-19 squeal.

Activity-aggression behavioural syndromes exist in males but not in females of the field cricket .

Previous studies on sex differences in behaviour have largely focused on differences in average behaviours between sexes. However, males and females can diverge not only in average behaviours but also in the direction of behavioural correlations at the individual level (i.e.

Transition-metal (oxy)nitride photocatalysts for water splitting.

Solar-driven water splitting based on particulate semiconductor materials is studied as a technology for green hydrogen production. Transition-metal (oxy)nitride photocatalysts are promising materials for overall water splitting (OWS) a one- or two-step excitation process because their band structure is suitable for water splitting under visible light. Yet, these materials suffer from low solar-to-hydrogen energy conversion efficiency (STH), mainly because of their high defect density, low charge separation and migration efficiency, sluggish surface redox reactions, and/or side reactions.

Distinctive optical transitions of tunable multicolor carbon dots.

Three types of carbon dots (CDs) are synthesized from isomers of phenylenediamine to develop multicolor nanomaterials with low toxicity, high stability, and high quantum yield. The distinctive electronic structures of CDs lead to the characteristic optical transitions, such as three colors of blue, green, and red, which are primarily attributed to the difference in configurations, despite the similar basic structures of conjugated systems. The excitation-independent emission and the single exponential decay of CDs indicate the single chromophore-like nature in each type of CD.
