Cordilleran Ice Sheet early deglaciation inferred from evolution of Late‐Pleistocene glacial Lake Dzulh Stun in east‐central British Columbia, Canada

Journal of Quaternary Science, EarlyView.
Abstract We document the early decay of the Late‐Pleistocene Cordilleran Ice Sheet in the central portion of the Rocky and Cariboo Mountains and the Rocky Mountain Trench in east‐central British Columbia. Glacial lakes impounded at the eastern margin of the ice sheet occupied watersheds on the west flank of the central Rocky Mountains, leaving ...

Reconstructing post‐crisis recovery in the hinterlands of Constantinople: A high‐resolution first‐millennium CE pollen record from Lake Yeniçağa (NW Türkiye)

Journal of Quaternary Science, EarlyView.
ABSTRACT Facing a novel plague pandemic, military invasions, and political–economic transformations, societies of the eastern Roman (Byzantine) empire had to adapt to a variety of pressures and new ways of exploiting their natural environments during the mid‐1st millennium CE.

Nonlinear scalar field equations in $\mathbb R^{N}$: mountain pass and symmetric mountain pass approaches

, 2010
We study the existence of radially symmetric solutions of the following nonlinear scalar field equations in $\mathbb{R}^N$: \begin{gather*} -\Delta u=g(u) \quad \text{in }\mathbb{R}^N,\\ u\in H^1(\mathbb R^N). \end{gather*} We give an extension of the existence results due to H. Berestycki, T. Gallouët and O.

Population dynamics of Townsend's big‐eared bats: effect of age and drought on survival

The Journal of Wildlife Management, EarlyView.
We estimated age‐specific yearly survival of female Townsend's big‐eared bats in Inyo and Mono Counties, California. We found that both juvenile and adult survival were negatively impacted by drought, and that detection probability was lower for hand‐recapture than for bats detected via pass‐through antenna arrays.

Dog attacks on wild desert tortoises: A risk model

The Journal of Wildlife Management, EarlyView.
Domestic dogs attack and severely injure wild desert tortoises at the urban and ex‐urban interface with deserts. Severe trauma to tortoises increased 4 times to shell and limbs and 16.5 times to the gular horn over the decades between the 1970s and 2000s. Tortoises were at exponential risk of severe trauma when living within 12 km of settlements, towns,

Valproic Acid Inhibits Ferroptosis and Improves Bone Integration in OVX Rats Through the AMPK/SIRT1 Pathway

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT The prevalence of postmenopausal osteoporosis (PMOP) has been steadily increasing. Ferroptosis has been recognized as a critical factor influencing the bone‐forming ability of bone marrow mesenchymal stem cells (BMSCs). Valproic acid (VPA), an HDAC inhibitor, has been suggested to play a role in regulating osteoporosis development; however ...
