Doppler-controlled microsurgical subinguinal varicocelectomy: a single centre experience

open access: yesВестник урологии
Introduction. Injury to the testicular artery during microsurgical subinguinal varicocelectomy (MSV) results in testicular atrophy in 20 – 40% of cases. The use of techniques that improve visualization of the testicular artery could increase the efficacy

Impact of robust optimization and beam configuration on the distribution stability of LET under delivery uncertainties in carbon‐ion therapy

open access: yesJournal of Applied Clinical Medical Physics, Volume 27, Issue 11, November 2026.
Abstract Background Carbon‐ion radiotherapy exploits high linear energy transfer (LET) to enhance biological effectiveness, and low dose‐averaged LET (LETd) within the target volume is associated with local recurrence in pancreatic cancer. Although robust optimization is widely used to improve dose robustness against delivery uncertainties, systematic ...

Novel Hybrid Sparse and Low-Rank Representation With Auto-Weight Minimax Lγ Concave Penalty for Image Denoising

open access: yesIEEE Access
Image denoising techniques often rely on convex relaxations, which can introduce bias into estimations. To address this, non-convex regularizers like weighted nuclear norm minimization and weighted Schatten p-norm minimization have been proposed. However,

A Comprehensive Review of GAN‐CNN Hybrid Methods for Intelligent Fault Diagnosis of Rotating Machinery

open access: yesEngineering Reports, Volume 8, Issue 10, October 2026.
This paper reviews recent advances in hybrid deep learning for intelligent fault diagnosis of rotating machinery, focusing on GAN‐ and CNN‐based architectures and their specialized variants. Hybrid GAN‐CNN methods are categorized into three groups: (1) optimized original GANs with CNN variants, (2) improved GAN architectures integrated with CNNs, and ...
