Selecting the best stable isotope mixing model to estimate grizzly bear diets in the Greater Yellowstone Ecosystem.

open access: yesPLoS ONE, 2017
Past research indicates that whitebark pine seeds are a critical food source for Threatened grizzly bears (Ursus arctos) in the Greater Yellowstone Ecosystem (GYE).

Single Crystals of Perylene Diimide‐Based Two‐Dimensional Covalent Organic Frameworks

open access: yesAdvanced Materials, EarlyView.
Synthesizing extended crystals of two‐dimensional covalent organic frameworks (2D COFs) has remained a major challenge. Here, we report a high‐temperature double‐modulator strategy that provides access to new perylene diimide (PDI)‐based COFs with crystal sizes of up to 50 µm.

Why Is the Mechanism Underlying the Chiral‐Induced Selectivity Effect Still Challenging?

open access: yesAdvanced Materials, EarlyView.
The chiral‐induced spin selectivity (CISS) effect is observed in many experimental configurations and for different materials. However, there are theoretical challenges in attempting to explain those results. A qualitative framework for explaining all the results is presented.

Super‐Resolution Ultrasound Based Cell Tracking With Polymeric Nanobubbles

open access: yesAdvanced Materials, EarlyView.
This study presents a super‐resolution ultrasound platform for tracking cells in vivo. Biocompatible polymeric nanobubbles are used as highly echogenic intracellular labels. Following the injection of cells and microbubbles, ultrasound localization microscopy (ULM) can dynamically match the microvascular architecture and individual cell trajectories ...

A food-based habitat-selection model for grizzly bears in Kluane National Park, Yukon

open access: yes, 1999
I examined the relationship between plant food abundance and diet, and habitat selection by grizzly bears (Ursus arctos) in the Alsek River Valley, Kluane National Park (KNP) in 1995 and 1996.

A Survey of Interlayer Interaction Models for Graphene and Other 2D Materials

open access: yesAdvanced Materials Interfaces, EarlyView.
Van der Waals interactions arising from electronic polarization at atomically close interfaces generate corrugated interlayer energy landscapes that govern normal and tangential tractions. This review presents an overview of quantum, atomistic, analytical, and continuum modeling approaches, highlighting their roles across length scales in capturing ...

Van der Waals Chromium Telluride Thin Films Prepared by Hybrid Pulsed Laser Deposition With Tunable Magnetism

open access: yesAdvanced Materials Interfaces, EarlyView.
Epitaxial Cr(1+δ)Te2 thin films were synthesized via hybrid Pulsed Laser Deposition (PLD) that combined Molecular Beam Epitaxy (MBE) techniques with PLD. Control of the Cr intercalation, δ, enabled modulation of magnetic anisotropy, Curie temperature, and transport properties.

Influence of Livestock and Electrified Fences on Livestock Depredation and Habitat Selection by Grizzly Bears in the Mission Valley, Montana

open access: yes, 2020
Balancing protection between livestock and carnivores has been a long-standing challenge in conservation. When encounters between carnivores and livestock or humans result in conflict or livestock depredation, the safety of both wildlife and humans are ...
