Comprehensive Evaluation and Analysis of Aging Performance of Polymer-Rich Anchoring Adhesives.

In civil engineering, with the increasing demand for structural reinforcement and renovation projects, polymer-rich anchoring adhesives have attracted much attention due to their performance advantage of having high strength and have become a key factor in ensuring the safety and durability of buildings. In this study, polymer-rich anchoring adhesives underwent three artificial aging treatments (alkali medium, hygrothermal, and water bath) to evaluate their aging performance. Alkali treatment reduced bending strength by up to 70% (sample 5#) within 500 h before stabilizing, while hygrothermal and water-curing treatments caused reductions of 16-51% and 15-77%, respectively, depending on adhesive composition.

Association between dietary theobromine and age-related macular degeneration: results from NHANES 2005-2008 and in vitro experiments.

Objective: To investigate the relationship between theobromine and age-related macular degeneration (AMD) using a nationwide representative sample of adults and in vitro experiments.

Methods: We analyzed data from the 2005-2008 years of the National Health and Nutrition Examination Survey (NHANES), which included 5485 participants with available data on dietary theobromine intake and AMD. Multivariable logistic regression and smoothing curve fitting were used to examine the potential correlations.

Lightweight insulator target detection algorithm based on improved YOLOX.

To address the challenges of high parameter volume, insufficient detection accuracy, and high false positive rates in traditional insulator target detection algorithms, this paper proposes a lightweight detection algorithm based on an enhanced YOLOX framework. First, Depthwise Separable Convolutions (DWConv) are employed to replace traditional convolutions, simplifying the model structure and reducing parameter count. Second, the Spatial Pyramid Pooling Fast-N (SPPF-N) module is introduced to substitute the traditional SPP module, and the last CSPLayer is removed, further compressing parameters while improving detection speed.

Filamentary Convolution for SLI: A Brain-Inspired Approach with High Efficiency.

Spoken language identification (SLI) relies on detecting key frequency characteristics like pitch, tone, and rhythm. While the short-time Fourier transform (STFT) generates time-frequency acoustic features (TFAF) for deep learning networks (DLNs), rectangular convolution kernels cause frequency mixing and aliasing, degrading feature extraction. We propose filamentary convolution to replace rectangular kernels, reducing the parameters while preserving inter-frame features by focusing solely on frequency patterns.

Single-cell RNA sequencing highlights a significant retinal Müller glial population in dry age-related macular degeneration.

The main challenge in dissecting the cells and pathways involved in the pathogenesis of age-related macular degeneration (AMD) is the highly heterogeneous and dynamic nature of the retinal microenvironment. This study aimed to describe the comprehensive landscape of the dry AMD (dAMD) model and identify the key cell cluster contributing to dAMD. We identified a subset of Müller cells that express high levels of Sox2, which play crucial roles in homeostasis and neuroprotection in both mouse models of AMD and patients with dAMD.

Oncological Outcomes of Intersphincteric Resection Versus Abdominoperineal Resection for ypT3 Low Rectal Cancer After Neoadjuvant Chemoradiotherapy: A Multicenter Retrospective Analysis.

Background: Sphincter preservation, crucial for patients traditionally facing abdominoperineal resection, was advanced by neoadjuvant chemoradiotherapy and intersphincteric resection.

Unsupervised Global and Local Homography Estimation with Coplanarity-Aware GAN.

Unsupervised methods have received increasing attention in homography learning due to their promising performance and label-free training.
