Voxel‐SLAM: A Complete, Accurate, and Versatile Light Detection and Ranging‐Inertial Simultaneous Localization and Mapping System

Advanced Intelligent Systems, EarlyView.
: In this work, Voxel‐SLAM (simultaneous localization and mapping) is introduced: a complete, accurate, and versatile LiDAR (light detection and ranging) ‐inertial SLAM system consisting of five modules: initialization, odometry, local mapping (LM), loop closure (LC), and global mapping (GM), all employing the same map representation, an adaptive voxel

Quantifying black carbon deposition over the Greenland ice sheet from forest fires in Canada [PDF]

, 2017
Black carbon (BC) concentrations observed in 22 snowpits sampled in the northwest sector of the Greenland ice sheet in April 2014 have allowed us to identify a strong and widespread BC aerosol deposition event, which was dated to have accumulated in the ...

Phylogenomics, ecomorphological evolution, and historical biogeography in Deuterocohnia (Bromeliaceae: Pitcairnioideae)

American Journal of Botany, EarlyView.
Abstract Premise Species of Deuterocohnia (17 spp.) show extraordinary variation in elevation (0–3900 m a.s.l.) and growth forms, and many have narrow geographic distributions in the west‐central Andes and the Peru‐Chile coast. Previous research using few plastid and nuclear loci failed to produce well‐resolved or supported phylogenies.

AI‐Assisted Customizable SERS‐Based Aptasensor for Label‐Free, Rapid, and Sensitive Detection of Tau: Comparative Analysis Using Random Forest and Convolutional Neural Networks

Analysis &Sensing, EarlyView.
A customizable SERS‐based aptasensor platform integrates aptamer‐functionalized gold nanoparticles with machine learning models (RF and CNN) to detect tau protein, a key biomarker for Alzheimer's disease. This rapid, label‐free detection system achieves a detection limit of 100 pM, enabling early diagnosis and monitoring of disease progression.

New partial skeleton of Homo habilis from the upper Burgi Member, Koobi Fora Formation, Ileret, Kenya

The Anatomical Record, EarlyView.
Abstract KNM‐ER 64061 is a partial skeleton from the upper Burgi Member of the Koobi Fora Formation (2.02–2.06 Ma) associated taphonomically and geochemically with a nearly complete mandibular dentition (KNM‐ER 64060) attributed to Homo habilis.
