Glacier recession since the Little Ice Age: Implications for water storage in a Rocky Mountain landscape

open access: yesArctic, Antarctic, and Alpine Research, 2019
Glaciers have significant influence on hydrology, vegetation, and wildlife in mountainous regions, and are receding globally. To quantify the impacts of sustained glacier loss, we mapped a complete set of glacier areas from the Little Ice Age (LIA) using

New techniques for old bones: Morphometric and diffeomorphometric analysis of the bony labyrinth of the Reilingen and Ehringsdorf Neandertals

open access: yesThe Anatomical Record, EarlyView.
Abstract Neandertals are known to possess very distinctive traits in their bony labyrinth morphology, such as an inferiorly positioned posterior canal and a very low number of turns in the cochlea. Hence, the inner ear has been often used to assess the Neandertal status of fragmentary fossils.

Volume-area scaling approach versus flowline model in glacier volume projections

open access: yesAnnals of Glaciology, 2007
Volume–area scaling provides a practical alternative to ice-flow modelling to account for glacier size changes when modelling the future evolution of glaciers; however, uncertainties remain as to the validity of this approach under non-steady conditions.

Dark Heritage Prospection ‐ Mapping the Treblinka II Extermination Camp Using a Magnetometer Survey and Integrated Archival Sources

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT The history of Nazi German extermination camps has, until recently, relied primarily on eyewitness testimony. Very few official documents detailing the facilities survived the war due to the special operation ‘Sonderaktion 1005’, dedicated to hiding their existence and extent.

Magnetoelastic Cell Monitoring System for Evaluating the Effects of Surface Chemistry on the Performance of Mesenchymal Stem Cell Growth

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT The recent clinical adoption of cell therapies has increased the need for more efficient, robust, and reproducible manufacturing technologies. Human mesenchymal stromal cells (hMSCs), a major component of the cell and immunotherapeutic market, remain challenging to manufacture at scale because they require surface attachment and are highly ...

The equilibrium flow and mass balance of the Taku Glacier, Alaska 1950–2006 [PDF]

open access: yesThe Cryosphere, 2008
The Taku Glacier, Alaska has advanced 7.5 km since the late nineteenth century, while all other primary outlet glaciers of the Juneau Icefield are in retreat.

On the Interpretation of L- and P-Band PolSAR Signatures of Polythermal Glaciers [PDF]

open access: yes, 2013
Long-wavelength (e.g. P- and L- band) SAR systems can penetrate tens of meters deep into ice bodies. Hence, they are sensitive to the ice surface as well as to sub-surface (volume) ice structures.

Relationship between changes in ice volume for each glacier and glacier size.

open access: yes, 2013
(a) ice volume calculated from the glacier surface elevation change between the corrected SRTM and DEM 1966, and (b) ice volume derived from the statistical relationship between the glacier area and ice volume in the Tuanjiefeng region.

A nanoplatform that induces dual‐amino acid deprivation to reverse tumor immunosuppression and enhance metabolic immunotherapy

open access: yesBMEMat, EarlyView.
ZIF‐8‐based nanoparticles co‐delivering CB‐839 (glutaminase inhibitor) and 1‐MT (IDO1 inhibitor), dual‐targeting glutamine/tryptophan metabolism to induce immunogenic cell death, activate STING, block kynurenine production, reverse immunosuppression, and enhance cancer immunotherapy to suppress primary/distant tumors.
