Background: Interval walking exercise (IWE) consists of repeated walking for 3 min with high intensity, followed by 3 min of walking with low intensity. A wearable robot is an exoskeleton system that is worn on the body and helps the body move.
Research Question: The purpose of this study is to verify the effects of performing IWE using Bot Fit (Samsung Electronics, Korea) on older adults.
Methods: The experimental group (EG; n = 10) performed the IWE program with Bot Fit, and the control group (CG; n = 12) performed the IWE program without Bot Fit, three times a week for six weeks. Both groups were evaluated for spatio-temporal parameters, pelvic movement, function, muscle power, and waist-to-hip ratio (WHR) at before, after three weeks and after six weeks of exercise.
Results: There was a significant difference between the two groups in the pelvic tilt range after six weeks of exercise (P < 0.05). The pelvic rotation range showed a significant difference after six weeks of exercise in the EG (P < 0.01). During the stance phase, rectus abdominis (RA) muscle power and its contraction ratio significantly increased after six weeks of exercise in the EG (P < 0.05). The WHR was significantly lower after six weeks of exercise in EG than in the CG (P < 0.05).
Significance: Bot Fit maximizes the normal walking effect, promotes correct posture and physical activity to prevent falls, improves quality of life (QOL). It has shown clinical effects and has been used for successful aging of older adults.

Mosses from the genus Sphagnum have experienced 350 million years of separate evolution, resulting in distinctive features, such as unlimited apical growth potential, unknown from other mosses. They are ecosystem engineers and the main components of peatlands. Although peatlands cover only a small part of Earth's landmass, they store more carbon than all living matter combined.

Premise: Phenology-the timing of developmental events-is one of the most effective ways to study the impacts of climate change on plants and ecosystems. However, it remains unknown whether phenology shows a linear or curvilinear response to spring warming.
Methods: We measured days to leaf out and flowering for dormant twigs of 12 woody species in seven temperature conditions, representing a wider range of temperatures than in previous studies, and tested whether responses of leaf out and flowering follow linear or curvilinear trends by comparing model fit of linear and second-order polynomial regressions.

Background: Floral diversity, a striking feature of angiosperm evolution, provides the impetus and rationale for linking pollinator-driven selection to speciation processes. Perhaps the most widely adopted model for pollinator-driven speciation is the Grant-Stebbins model, in which plant populations locally adapt to the most effective pollinator, leading to floral ecotype formation and, eventually, reproductive isolation and speciation. However, modelling and empirical studies suggest that populations need not adapt to the most effective pollinator, and major floral transitions remain poorly explained.

Background And Aims: The known diversity of zosterophylls, the dominant tracheophytes at the beginning of the Devonian, expanded significantly due to discoveries that intervened since the latest large phylogenetic treatment targeting the group, almost 30 years ago. Past phylogenetic treatments reached incomplete resolution or conflicting results on relationships among zosterophylls and between zosterophylls and lycopsids (which are traditionally thought to have evolved from among zosterophylls). This state of the knowledge emphasizes the need for reevaluation of zosterophyll relationships.

A task-oriented dialogue system with adaptability to user personality could potentially improve dialogue task performance in terms of task success and user satisfaction. In practice, however, the implementation of such a dialogue system would be challenging because of our limited understanding of how user personality influences dialogue task performance. Understanding these influences is essential for developing dialogue strategies that adapt to user personalities, allowing a dialogue system to cater to different users and thereby improve task performance.
