A novel surgical technique for revision anterior cruciate ligament reconstruction using an isolated rectus femoris tendon autograft.

Introduction: Only a few anatomic studies have described an isolated rectus femoris tendon autograft for anterior cruciate ligament (ACL) reconstruction. This study aims to demonstrate a new surgical technique utilising the rectus femoris tendon for ACL reconstruction. This study hypothesises that the rectus tendon autograft will yield satisfying postoperative outcomes in terms of stability, with minimal complications at the harvest site.

Multivariate Time Series Information Bottleneck.

Time series (TS) and multiple time series (MTS) predictions have historically paved the way for distinct families of deep learning models. The temporal dimension, distinguished by its evolutionary sequential aspect, is usually modeled by decomposition into the trio of "trend, seasonality, noise", by attempts to copy the functioning of human synapses, and more recently, by transformer models with self-attention on the temporal dimension. These models may find applications in finance and e-commerce, where any increase in performance of less than 1% has large monetary repercussions, they also have potential applications in natural language processing (NLP), medicine, and physics.

Direct Accessibility of the Fundamental Constants Governing Light-by-Light Scattering.

Quantum field theory predicts that the vacuum exhibits a nonlinear response to strong electromagnetic fields. This fundamental tenet has remained experimentally challenging and is yet to be tested in the laboratory. We present proof of concept and detailed theoretical analysis of an experimental setup for precision measurements of the quantum vacuum signal generated by the collision of a brilliant x-ray probe with a high-intensity pump laser.
