Folding-based Compression of Point Cloud Attributes

, 2020
International audienceExisting techniques to compress point cloud attributes leverage either geometric or video-based compression tools. We explore a radically different approach inspired by recent advances in point cloud representation learning.

Application of Digital, Web‐Based, and Online Strategies in Point of Care Ultrasound (POCUS) Training: A Scoping Review

Health Science Reports, Volume 9, Issue 5, May 2026.
ABSTRACT Background Ultrasound is a commonly used modality in healthcare. Point of care ultrasound (POCUS) is performed at the patient's bedside with many purported benefits. Aims Given its increasingly popularity, this scoping review examined the role of digital, web‐based, and online educational strategies for POCUS. Methods Adhering to Joanna Briggs

No evidence for missed mutualists in an invasive plant with the buzz pollination syndrome

Ecosphere, Volume 17, Issue 4, April 2026.
Abstract The missed mutualist hypothesis predicts that the absence of mutualistic partners poses a barrier to introduced species becoming invasive. Yet, some alien plants thrive despite potential dependence on certain pollinators. For example, buzz‐pollinated plants typically have specialist floral morphologies and benefit from buzz pollinator behavior

Microbial metabolites in tumor epigenetic regulation

iMeta, Volume 5, Issue 1, February 2026.
The gut microbiome modulates tumor epigenetic regulation through bioactive metabolites derived from dietary substrates. Microbiota‐produced SCFAs, secondary BAs, one‐carbon metabolites, and tryptophan‐derived ligands regulate histone acetylation, DNA methylation, and chromatin remodeling via HDAC, DNMT, AhR, and metabolic cofactor‐dependent pathways ...

All‐Optical Diffractive Operators for Rapid, Computer‐Free Morphological Transformations

Nanophotonics, Volume 15, Issue 4, 24 February 2026.
This paper shows an all‐optical, computer‐free approach to realize morphological transformations on visual data. Free‐space optical devices consisting of successive diffractive layers are trained through a deep learning‐based optimization process to perform erosion and dilation for images with diverse styles.

3D point cloud compression

, 2019
International audienceIn recent years, 3D point clouds have enjoyed a great popularity for representing both static and dynamic 3D objects. When compared to 3D meshes, they offer the advantage of providing a simpler, denser and more close-to-reality ...

A Queue‐Aware Extension to BBR for Low‐Latency Transport in Video Applications

IET Communications, Volume 20, Issue 1, January/December 2026.
This work addresses a long‐standing challenge in congestion control for real‐time video delivery: how to reliably maintain low latency in highly dynamic networks without sacrificing throughput. We explicitly model the excess queue incurred during bandwidth probing as a “queue debt” and then systematically “repay” this debt in subsequent phases by ...

A Systematic Literature Review on Auction Mechanisms: Insights From the Last Decade and Future Directions

Journal of Economic Surveys, Volume 39, Issue 5, Page 1971-1998, December 2025.
ABSTRACT This study reports the results of a systematic literature review on auctions mechanism. Auctions are a very popular practice employed in many fields but does not exist a research that investigates the use of auctions under a cross‐disciplinary approach. This work is focused on analyzing which are the areas where auctions are mostly adopted and
