Perception, history, and science: coherence or disparity in the timing of the Little Ice Age maximum in southeast Iceland? [PDF]

open access: yes, 2005
In Iceland, studies that integrate local perceptions about the landscape with scientific evidence of change have been few. This article presents a case study from southeast Iceland that has two main objectives.

When Do Single‐Species Occupancy Models Outperform Multispecies Models?

open access: yesEcology and Evolution
Occupancy models have become increasingly popular for species monitoring and assessment, in part, because detection/non‐detection data are readily obtained using a variety of methods.

The spatial variation of Asian dust and marine aerosol contributions to glaciochemical signals in central Asia [PDF]

open access: yes, 1992
Short-term (6 months to 17 years) glaciochemical records have been collected from several glacier basins in the mountains of central Asia. The spatial distribution of snow chemistry in central Asia is controlled by the influx of dust from the large ...

Including debris cover effects in a distributed model of glacier ablation [PDF]

open access: yes, 2012
Distributed glacier melt models generally assume that the glacier surface consists of bare exposed ice and snow. In reality, many glaciers are wholly or partially covered in layers of debris that tend to suppress ablation rates.

Karakoram geodetic glacier mass balances between 2008 and 2016: persistence of the anomaly and influence of a large rock avalanche on Siachen Glacier

open access: yesJournal of Glaciology, 2019
Karakoram glaciers experienced balanced or slightly positive mass budgets since at least the 1970s. Here, we provide an update on the state of balance of Central and Eastern Karakoram glaciers (12 000 km2) between 2008 and 2016 by differencing DEMs ...

Enhancing the Ultrasonic Welding of Wood Using 3D Printed Lignin Energy Directors

open access: yesAdvanced Science, EarlyView.
Sustainable manufacturing for lightweight structures using ecofriendly materials will be key to reducing material consumption and lowering carbon footprints. Here, an approach is presented to weld wood using ultrasonic vibrations with material at the joint interface to direct energy.

Seismic Imaging of the Arctic Subsea Permafrost Using a Least-Squares Reverse Time Migration Method

open access: yesRemote Sensing
High-resolution seismic imaging allows for the better interpretation of subsurface geological structures. In this study, we employ least-squares reverse time migration (LSRTM) as a seismic imaging method to delineate the subsurface geological structures ...

YKT6 Promotes Bladder Cancer Progression by Stabilizing β‐catenin Through USP7‐Mediated Deubiquitination

open access: yesAdvanced Science, EarlyView.
The SNARE protein YKT6 is upregulated in bladder cancer (BLCA), correlating with poor prognosis. YKT6 promotes tumor proliferation and metastasis by activating Wnt/β‐catenin signaling. It recruits Ubiquitin‐Specific Peptidase 7 (USP7) to deubiquitinate and stabilize β‐catenin, enhancing its nuclear accumulation and driving oncogenic gene expression ...

A fifty year record of winter glacier melt events in southern Chile, 38°–42°S [PDF]

open access: yes, 2012
Little is known about the frequency and potential mass balance impact of winter glacier melt events. In this study, daily atmospheric temperature soundings from the Puerto Montt radiosonde (41.43°S) are used to reconstruct winter melting events at the ...
