Prediction of knee loads during activities of daily living using custom instrumented insoles and machine learning.

J Biomech

August 2025

Department of Kinesiology, University of Maryland, College Park, United States; Neuroscience and Cognitive Science Program, University of Maryland, United States. Electronic address:

Medial joint contact force, knee adduction moment, and knee flexion moment are key mechanical risk factors of knee osteoarthritis, yet calculating these knee loads traditionally requires time-intensive procedures with a gait laboratory. Integrating wearable technologies, such as instrumented insoles, with neural networks offers a promising avenue for rapid and accessible estimation of these variables in clinical environments. This study aimed to estimate knee loads during walking, running, sit-to-stand, and stand-to-sit activities using a recurrent neural network model trained on wearable sensor data.

The placenta is a dynamic, embryo-derived organ essential for fetal growth and development. While all eutherian mammals have placentas composed of fetal-derived trophoblasts that mediate maternal-fetal exchange, their anatomical and histological structures vary across species due to evolutionary divergence. Despite the cellular heterogeneity of porcine trophoblasts in vivo, understanding the mechanisms driving porcine placental development has been limited by the lack of in vitro models replicating this heterogeneity.

A Missing Link: The Double-Slit Experiment and Quantum Entanglement.

Entropy (Basel)

July 2025

Literature, Theory, and Cultural Studies Program, Philosophy and Literature Program, Purdue University, West Lafayette, IN 47907, USA.

This article reconsiders the double-slit experiment by establishing a new type of relationship between it and the concept of entanglement. While the role of entanglement in the double-slit experiment has been considered, this particular relationship appears to have been missed in preceding discussions of the experiment, even by Bohr, who extensively used it to support his argument concerning quantum physics. The main reason for this relationship is the different roles of the diaphragm with slits in two setups, S1 and S2, defining the double-slit experiment as a quantum experiment.
