Design and Performance of the Wide-Field X-Ray Monitor on Board the High-Energy Transient Explorer 2

open access: yes, 2003
The Wide-field X-ray Monitor (WXM) is one of the scientific instruments carried on the High Energy Transient Explorer 2 (HETE-2) satellite launched on 2000 October 9. HETE-2 is an international mission consisting of a small satellite dedicated to provide

Ascertaining the nature and timing of mire degradation : using palaeoecology to assist future conservation management in Northern England [PDF]

open access: yes, 2017
This study was initiated under contract VT0419 from English Nature (Natural England) to CECQR. In 2015, additional funding was provided by the Yorkshire Peat Partnership, for 210Pb dating, to refine age–depth estimates.

Biological, Biogeochemical, Bio‐Optical, and Physical Variability of the Southern Ocean Along 150°W and Its Relevance to the Great Calcite Belt

open access: yesGlobal Biogeochemical Cycles, Volume 39, Issue 8, August 2025.
Abstract We report hydrographic and biogeochemical measurements from a meridional transect performed along 150°W, 30°S to 60°S in the Southern Ocean, plus Polar waters to the east. Both of these areas are sites of annual high‐reflectance features in ocean color remote sensing, which were heretofore never confirmed with in situ measurements.

AstroGeoFit. A Genetic Algorithm and Bayesian Approach for the Astronomical Calibration of the Geological Timescale

open access: yesPaleoceanography and Paleoclimatology, Volume 40, Issue 8, August 2025.
Abstract Variations in Earth's orbit and axial tilt induce climatic changes which are recorded in sedimentary deposits. The frequencies of these cyclical variations are integer combinations of the main secular frequencies of the solar system. Analyzing these cycles in sedimentary records can help establish an astronomical time scale for the geological ...

Evaluation of Gamma Penetration through Plain Carbon Steels

open access: yes, 2014
In this study, 1010, 1040, 1050 and 1090 carbonized steels were investigated against gamma radioisotope sources on their gamma attenuation properties. Co-60, Cs-137 and Ir-192 gamma radioisotopes which are commonly used in industrial applications were ...

Design of Potent Mannose‐6‐Phosphate Derivatives as Ligands for CI‐M6P/IGF2R Using Fluorescence Polarization Assay

open access: yesChemistry – A European Journal, Volume 31, Issue 41, July 22, 2025.
We designed and synthesized novel mannose‐6‐phosphate (M6P) derivatives to enhance their binding affinity for the CI‐M6P/IGF2 receptor, which plays a key role in lysosomal targeting. Using a fluorescence polarization assay, we evaluated di‐, tri‐, and penta‐M6P peptides and modified M6P analogs.

Double‐Click Strategy Combining CuAAC and (Thia‐) Diels‐Alder Reactions; Application Toward Peptide Labeling

open access: yesChemistry – A European Journal, Volume 31, Issue 41, July 22, 2025.
A double click‐strategy combining copper‐catalyzed azide‐alkyne cycloaddition with (thia‐)Diels‐Alder reactions involving a reactive s‐cis‐constrained diene is reported. Three different one‐pot protocols (i.e., sequential or three‐component reactions) are proposed and offer valuable guidance for future applications.
