Summary: This study examines the relationship between energy consumption and economic growth in China from 1980 to 2011, as well as the situation in the Eastern, Middle, and Western regions of China from 1980 to 2008. Significant regional differences in energy intensity were found, and the overall results do not support the hypothesis that China's energy use accords with the biological relationship mentioned. Alternative relationships were found to provide a better fit to the data.

Summary: Demosponges are filter-feeding organisms composed of modular units. The filtration rate of demosponges is related to their size, but the relationship varies depending on the type of sponge. Small single-osculum sponges exhibit a scaling relation between filtration rate and volume, while multi-oscula sponges and large single-osculum sponges have different scaling relationships. The observed decline in volume-specific filtration rate from small to large sizes is discussed.

Summary: We investigate the scaling form of appropriate timescales in rotating turbulent flows by analyzing time-dependent correlation functions. We obtain precise estimates of the dynamic exponents associated with these timescales and compare them with the commonly measured equal-time exponents. Theoretical predictions based on the multifractal formalism are validated through extensive numerical simulations of a shell model for rotating flows.

Summary: Quantifying uncertainty in forest assessments is challenging due to various sources of error and approaches to propagation. Model fit uncertainty is more important than uncertainty in individuals when dealing with large-scale assessments. Four different approaches to representing model uncertainty were compared and found to be in good agreement. Uncertainty in model fit did not vary with the number of trees in the inventory, while uncertainty in predicting individuals was higher with smaller numbers of trees. The importance of uncertainty sources varied with forest type, with larger importance in poor model fit situations. Both sources of allometric uncertainty should be accounted for, but when large numbers of individuals are involved, the contribution of uncertainty in predicting individuals can be ignored.

Summary: The distribution and abundance of disease vectors like mosquitoes are changing due to factors such as climate change, invasions, and vector control strategies. Most models currently ignore the nonlinear relationship between wing length and reproduction in mosquitoes, leading to potential biases in population growth estimates. Incorporating hyperallometric relationships in future disease vector models is crucial for accurately predicting changes in mosquito distribution.

Summary: Human finger joints are traditionally simplified as rigid joints in robotic hand design and biomechanical hand modelling, but the effect of different joint configurations on hand performance is not well understood. This study investigates the grasping performance of hands with rigid and flexible joints using a computational human hand model. The results show that the rigid joint configuration leads to reductions in hand contact force, pressure, and area compared to the flexible joint configuration. Grasping quality can be significantly reduced by the rigid joint configuration due to its weak rotational stiffness.

Summary: This study aims to determine the contribution of major muscles and the energy flow in the human musculoskeletal system during walking at different speeds. Gait experiments were performed, and muscle forces and mechanical work were calculated. The results showed that different muscles play different roles in energy absorption and generation during different phases of walking. These findings provide insights into human musculoskeletal behaviors during locomotion and can be applied in the bio-design of assistive devices.

Summary: This research developed a bioinspired heel pad with optimized inner structures inspired by the human heel pad, which showed great cushioning performance. Magnetic resonance imaging (MRI) technology and literature were used to determine the distinct structures of the human heel pad. Four bionic heel pads made of soft rubber and resin materials, with and without inner structures, were tested through finite element simulations. The results showed that the bionic heel pad with soft rubber material and inner structures had the best cushioning performance, reducing peak vertical ground reaction force (GRF) during walking by 28.0%.

Summary: The study aimed to investigate the dyadic relationships between perceived social support, illness uncertainty, anxiety, and depression among lung cancer patients and their family caregivers. A total of 308 patient-caregiver dyads were included, and questionnaires were used to assess their perceived social support, illness uncertainty, anxiety, and depression. The findings showed that both patient and caregiver perceived social support had actor and partner effects on anxiety and depression, and illness uncertainty mediated the effect of social support on anxiety and depression. Lung cancer stage played a moderating role in patient-caregiver dyads.

Summary: Degenerative disc disease (DDD) is a global public health issue that affects patient health and quality of life. Artificial total disc replacement (A-TDR) is an effective method for treating symptomatic DDD, but current devices lack the ability to replicate the multidirectional stiffness of natural intervertebral discs (IVDs). This study develops a bioinspired intervertebral disc (BIVD-L) that reproduces the multidirectional stiffness needed for physiological kinematic behaviors, providing new insights for the design of A-TDR devices.

Summary: This review examined the anthropometric, physiological, and physical profiles of elite snowboarding athletes. The findings suggest that elite speed-based and skill-based athletes generally have low body fat percentages, and differences exist in height and body mass between male speed-based and skill-based athletes. The predominant energy system in snowboarding is anaerobic metabolism, while muscle oxidative metabolism can aid in recovery. Lower-body strength, eccentric force production, and explosive concentric power production are crucial for various aspects of snowboarding performance. Further research is needed to explore anthropometry, energy system contributions, and training effects across different snowboarding disciplines.
