Oxygen isotope variability in the IIIAB iron meteorites and their relationship to main group pallasites

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract The light element distribution in planetary cores and the processes driving core evolution in rocky planets are poorly understood. Magmatic iron meteorites are samples from the cores of ancient embryonic planetesimals and therefore provide a window into the processes governing core evolution. We performed high precision oxygen isotope analyses

Root surface biomodification in periodontal therapy: Biological rationale and clinical applications

open access: yesPeriodontology 2000, EarlyView.
Abstract Regenerative periodontal therapy aims to form new cementum, periodontal ligament, and alveolar bone, all sealed by gingival tissue. The root surface acts as the wound margin during this regeneration process. Root surface biomodification (root conditioning/root decontamination), therefore, seems instrumental in promoting surface decontamination

A Quantitative Analysis of an Orphaned Set of Chipped Stone Tools in an Archaeology Teaching Collection

open access: yes, 2019
This report is the result of a semester-long project in Archaeological Method and Theory (ANTH 4620) at the University of Minnesota Duluth (UMD). Carried out in the Fall of 2019 as the laboratory component of a class with mostly junior and senior level ...

Testing coir (coconut) fiber as a novel, biodegradable material for coral reef restoration: coir interactions with larval and juvenile corals

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Coral populations have declined in recent decades, largely due to anthropogenic climate change. In response, coral restoration projects are being implemented, and rubble stabilization is one such approach. Rubble beds form when dead coral fragments accumulate on the seafloor and can be mobilized by water flow.

Outcrop and subsurface characterisation of a mixed tidal and wave‐influenced coastline (Triassic Red Beds, SE Spain)

open access: yesSedimentology, EarlyView.
ABSTRACT Paralic depositional systems are complex and heterogeneous sedimentary environments, presenting challenges for predicting reservoir architecture and connectivity. Their stratigraphic and facies variability arises from the dynamic interplay between fluvial, tidal and wave processes, and their sensitivity to sea‐level fluctuations, sediment ...

Stone tools : theoretical insights into human prehistory /

open access: yes, 1996
Lithic analysts have been criticized for being atheoretical in their approach, or at least for not contributing to building archaeological theory. This volume redresses that balance.

High‐elevation adaptation and gestational hypoxia jointly shape vascular development in a rodent placenta

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend We investigated how environmental hypoxia and genetic adaptation to high altitudes jointly impact the development of the placental exchange surface in ways that might protect fetal growth potential. We used wild‐derived, lab‐born North American deer mice (Peromyscus maniculatus) from low‐elevation and high‐elevation environments (

Vascular smooth muscle cell mechanotransduction: Pathways, phenotypes and emerging technologies

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Vascular smooth muscle cells are exposed to mechanical stimuli from the blood flow and the extracellular matrix. The cells sense the signals from cyclic stretch, shear stress, hydrostatic pressure and matrix stiffness through specialized mechanosensors, such as mechanosensitive ion channels or cell surface receptors including ...

From Association to Mechanism: Regulatory Annotation and Pathway Mapping of Genes Surrounding Breast Cancer Risk Variants

open access: yesComputational and Systems Oncology, Volume 6, Issue 1, December 2026.
ABSTRACT Inherited factors account for a large share of breast cancer susceptibility, yet the biological consequences of most risk variants are still poorly understood. To address this gap, we studied 175 breast cancer risk variants confirmed by genome‐wide association studies and gathered the genes that lie near them.

Study of Liquid Flow Through a Channel With Adjacent Porous Domains of Different Material Properties

open access: yesProceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.
ABSTRACT A common subject in engineering disciplines is the study of flow in and around fractures or channels with adjacent porous domains. In this work, a unified approach based on the Theory of Porous Media (TPM) with an embedded Phase‐Field (PF) fracture model is used to investigate a flow scenario, where a channel separates two porous domains with ...
