Summary: The study found that unilateral transfemoral prosthesis users maintain dynamic balance through different segment-to-segment cancellation strategies, with significant differences observed in the sagittal and transverse planes but not in the frontal plane. This research is important for understanding the mechanisms of dynamic balance control in prosthesis users and improving gait safety.

Summary: This study compared the accuracy of two methods based on MIMUs- SDI and BM- in estimating body CoM. The results showed that SDI had lower RMSE in tasks with little or no oscillations, while BM performed better in tasks with larger CoM displacement. Moreover, higher correlation coefficients were obtained between the posturographic parameters obtained with the BM and the OS.

Summary: A 3D multi-segment hand-specific thermoregulation model was developed to predict skin temperature, considering cold-induced vasodilation in fingers. The model, based on realistic anatomical and physiological information, divided the hand into 17 segments and included heat transfer mechanisms such as metabolism and blood perfusion. The model showed good agreement with experimental data and can enhance working efficiency, safety, health, and wellbeing in cold environments.

Summary: Non-contact measurement methods based on computer vision have the potential to accurately and reliably measure structural surface displacement and strain. Traditional methods, however, are limited by their reliance on natural texture features and susceptibility to environmental conditions. To address these limitations, a time-domain visual measurement technique based on image phase information is proposed, which extracts phase information using 2D Gabor filters and performs dense optical flow estimation to obtain robust 3D displacement measurements. This technique has shown promising results in both synthetic and real-world environments, especially for complex structural components with asymmetry.

Summary: This paper proposes and validates a drift-free 3D orientation and displacement estimation method based on a single IMU, which reduces drift by assuming quasi-cyclical movement and defines a functional coordinate system. The method provides accurate orientation and displacement estimates for human movements.

Summary: The energy-based seismic design method considers various factors such as frequency content, duration, pulse type of seismic excitation, and hysteretic behavior. The study proposes a new practical method to estimate the distribution of seismic input energy on moment-resisting frame (MRF) buildings. The method was validated through testing on benchmark MRF-type buildings, showing accurate results for predicting nonlinear seismic demands without the need for computationally expensive analyses.

Summary: This study assessed six satellite-based Leaf Area Index (LAI) estimation methods and found that radiative transfer modeling-based methods performed well for low to medium LAI but underestimated high LAI. Cubist regression models achieved high accuracy but did not generalize well between sites. Additionally, the red edge bands and vegetation index from Sentinel-2 satellite provided complementary information for LAI estimation. The thermal-based two-source energy balance model was more sensitive to positive LAI biases.

Summary: The roughness of the land surface is an important factor in the exchange of energy and other variables between land and atmosphere. This study proposes modifications to the parameterizations of land roughness in a land component of a climate model. The modifications improve the model's representation of land surface temperature and wind speed, bringing them into better agreement with observations.

Summary: A wearable framework based on MIMU networks for obtaining body center of mass acceleration and velocity was proposed and successfully validated in lower-limb amputees. Using multiple MIMUs on the trunk and both legs, as well as additional MIMUs on the thighs, resulted in high consistency and accuracy in estimating velocity and acceleration in different directions.

Summary: This article investigates the water requirements of mountain communities in the Himalayas and the impact of glacier melt on water resources. By estimating mass balance, the authors assess the health of glaciers and future water availability. The findings suggest that the loss of glaciers will increase the vulnerability of communities in the region, highlighting the need for improved adaptation strategies to enhance resilience.

Summary: The study found that colder temperatures did not lead to more conflict in Europe between 1000 and 1980 CE. The impact of temperature on conflict is context dependent, and identifying mediating factors should be a priority.

Summary: The study found that between two-thirds and three-quarters of Early Anglo-Saxon individuals had ancestry from continental northwest Europe, while between a quarter and one-third had local ancestry. In contrast, 50-70% of Middle Anglo-Saxon skeletons were of local ancestry, while 30-50% were of continental northwest Europe ancestry. This suggests that ancestry in Early Medieval Britain was mixed and mutable, similar to what it is today.

Summary: Studies over the last decade have shown contrasting conclusions on the impact of climate change on conflict among the Classic Maya, with increasing summer temperatures exacerbating conflict while annual rainfall variation has no effect. This finding is important for understanding conflict in the Maya region during the Classic Period and contributes to the ongoing discussion on the potential impact of contemporary climate change on conflict levels. The impact of climate change on conflict is context dependent and varies based on different factors.

Summary: This study explores the authentication procedures of shrunken heads in museum collections using micro-CT scanning. The correlative tomographic approaches provide valuable insights into determining if a shrunken head was made from human remains and challenge the previously conceptualized dichotomy of ceremonial or commercial.
