Discorpy: algorithms and software for camera calibration and correction
Discorpy, a Python package for camera calibration, provides robust tools to independently correct radial and perspective distortion of varying strengths using a single calibration image.Camera or lens‐based detector calibration is essential for spatial accuracy in applications like dimensional tomography, optical metrology, and computer vision.

An endochondral differentiation process in the CEPs drives pathologic disc calcification in aging LG/J mice, and NP cell hypertrophic transdifferentiation secondarily contributes. Supplementing drinking water with 80 mM K3Citrate during aging markedly reduced disc calcification, attenuated NP cell transdifferentiation, and mildly improved NP and AF ...

This study identifies BRD4 as a key regulator in intervertebral disk degeneration (IDD), linking its upregulation to NP cell senescence and disrupted ECM metabolism through the BRD4/MAP2K7/PGF signaling cascade, offering a potential therapeutic target for IDD treatment.

Neural Network Surrogate and Projected Gradient Descent for Fast and Reliable Finite Element Model Calibration: a Case Study on an Intervertebral Disc [PDF]
Accurate calibration of finite element (FE) models is essential across various biomechanical applications, including human intervertebral discs (IVDs), to ensure their reliability and use in diagnosing and planning treatments. However, traditional calibration methods are computationally intensive, requiring iterative, derivative-free optimization ...

This study demonstrates that aging induces oxidative stress and inflammation in the hematopoietic immune system, resulting in immune homeostasis dysfunction, including alterations in B cells and hematopoietic stem cells, senescent cells (SnCs) accumulation, and senescence‐associated secretory phenotypes (SASPs) production. Notably, the study highlights

Clinical Features of Seven COL2A1 Variations in Chinese Children With Type II Collagen Disorders
ABSTRACTAimType II collagen, encoded by the collagen type II alpha 1 (COL2A1) gene, is crucial for the structure of cartilage. This study aims to improve our understanding of Spondyloepiphyseal Dysplasia Congenita (SEDC) caused by mutations in COL2A1.

Holistic Decomposition Convolution for Effective Semantic Segmentation of 3D MR Images [PDF]
Convolutional Neural Networks (CNNs) have achieved state-of-the-art performance in many different 2D medical image analysis tasks. In clinical practice, however, a large part of the medical imaging data available is in 3D. This has motivated the development of 3D CNNs for volumetric image segmentation in order to benefit from more spatial context.
