Extended depth‐of‐field reflected‐light microscopy with a low‐cost robotic microscope and Fiji focus stacking: Workflow integration and baseline evaluation

Juan M, Ballesteros · Carlos M, Garzón

Abstract Optical reflected‐light microscopy is widely used in mechanical and tribological testing laboratories, but its limited depth of field (DOF) restricts imaging of non‐planar post‐test surfaces when high‐NA objectives are needed to resolve fine features. Here we present a low‐cost robotic microscopy system (bill...

Comparison of anterolateral versus posterior lumbar fusion techniques in obese patients: a systematic review and meta-analysis

Juan Alejandro Restrepo Buitrago · Natalia Cruz Tobón · Esteban Enrique Preciado Mesa · Carlos Alberto Rivera Suárez

Obesity increases the risk of developing lumbar spine disease and the need for subsequent surgical intervention. However, there is no consensus regarding the safety profiles and quality-of-life (QoL) outcomes of different lumbar interbody fusion (LIF) approaches in obese patients. This review compares perioperative, po...

Bayesian Youden index for algorithmic evaluation under class imbalance: mathematical foundations with applications to insulin resistance and diabetes progression

Aquiles, Darghan · Ariel Iván, Ruiz-Parra · Jorge Eduardo, Caminos · Nair, González · y 2 más

Background The evaluation of binary classifiers under real-world conditions requires metrics that account for the dependence of predictive performance on disease prevalence. Classical accuracy metrics, including the Youden index, condition on the true class and remain invariant to changes in class distribution, making...
