Estimates of Spawning Stream Contributions to an Imperilled Bull Trout Metapopulation Utilizing Otolith Geochemistry and Redd Counts

Ecology of Freshwater Fish, Volume 35, Issue 3, July 2026.
ABSTRACT Migratory fish species have experienced substantial declines throughout aquatic habitats, but actions to manage and conserve migratory species require a better understanding of the relative contributions of local populations to the metapopulation.

Yb:YAG Transparent Ceramics by Double‐Step Sintering—A Comparison Between HIP and FAST Postsintering Treatments

Journal of the American Ceramic Society, Volume 109, Issue 7, July 2026.
Fast is a viable alternative to HIP for the production of transparent YAG ceramics. ABSTRACT The potential of the field‐assisted sintering technique (FAST) as a novel postdensification method for densifying pre‐sintered transparent Yb‐doped yttrium aluminum garnet (Yb:YAG) ceramics was evaluated.

Clinical, Radiographic, and Histopathologic Features of Human Perigraftitis

Journal of Esthetic and Restorative Dentistry, Volume 38, Issue 7, Page 1300-1314, July 2026.
ABSTRACT Objective Perigraftitis is a biologic complication associated with dental implants placed in grafted bone, distinct from peri‐implant mucositis and peri‐implantitis. This report further characterizes its clinical, radiographic, and histopathologic features.

Comparison of 1064‐nm Picosecond and Q‐Switched Neodymium‐Doped Yttrium Aluminum Garnet Lasers for Melasma in Asian Women: A Randomized Double‐Blind Split‐Face Trial

Journal of Cosmetic Dermatology, Volume 25, Issue 7, July 2026.
ABSTRACT Background Melasma is a chronic, relapsing facial hyperpigmentation that remains challenging to treat in medium‐to‐dark phototypes. Aims To compare the efficacy, safety, tolerability, and recurrence of 1064‐nm picosecond neodymium‐doped yttrium aluminum garnet laser treatment versus 1064‐nm Q‐switched neodymium‐doped yttrium aluminum garnet ...

Endophyte‐induced systemic spatial reprogramming of metabolism in Populus trichocarpa roots under drought

New Phytologist, Volume 251, Issue 1, Page 438-454, July 2026.
Summary Beneficial, facultative endophytes help plants thrive in challenging environments by altering their host's metabolism, but how these cellular scale metabolic changes propagate to the systems biology scale is unknown. In this work, we employed a high‐resolution chemical imaging approach to map metabolic changes at the Populus trichocarpa root ...

Multi‐LiDAR Observations of Coastal Atmospheric Duct Evolution in Hampton Roads

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 12, 28 June 2026.
Abstract To better understand the influence of atmospheric ducts on radio frequency (RF) operations, continuous high‐resolution observations of temperature and water vapor are essential. Hampton University's (HU) 48‐inch Raman‐Mie LiDAR provides such measurements through rotational and vibrational Raman techniques, enabling detailed monitoring of ...

Al–Cu Composite Casting of Laser‐Deoxidized Copper: Bonding, Interfacial Chemistry, and Thermal Conductivity

Advanced Engineering Materials, Volume 28, Issue 12, 17 June 2026.
This study investigates laser‐based oxide removal of Cu inserts in oxygen‐free conditions and examines long‐term oxidation kinetics and surface chemistry under different atmospheres via X‐ray photoelectron spectroscopy. Al–Cu compound casting with differently oxidized surfaces is performed, and intermetallic phase formation, morphology, and thermal ...

Multimethod Microstructural Diagnostics of Polymer Electrolyte Membrane Water Electrolysis Cell Components Uncovering Diverging Degradation Pathways After Short‐Term Testing

ChemElectroChem, Volume 13, Issue 12, 17 June 2026.
This study probes why polymer electrolyte membrane electrolyzers lose efficiency under different operating profiles. Using electrical tests, microscopy, and spectroscopy, Ti‐PTL passivation is established as the dominant cause for increased Ohmic resistance in samples aged under constant and triangular current profiles for 88 h.
