Vanadium Isotopic Compositions of the High‐3He/4He Baffin Island Lavas

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.
Abstract The isotopic composition of vanadium (V) in hotspot lavas provides new insight into the source of deep mantle heterogeneities. We measured V isotopic compositions in Paleogene Baffin Island lavas, which erupted above the Iceland plume head, to constrain the mantle plume source. These lavas have V isotopic compositions that are lighter (−0.96 ±

Revitalization of Axial Flow Pump/Turbine h26 Test Rig

open access: yes, 2016
Various solutions are available in the market to enhance the quality of laboratory experiments, but the majorities are expensive. In this study, we present a low-cost approach for the automation and computer aided control of an axial flow pumpturbine test rig, which can be easily adapted to varying demands of laboratory applications.

Effect of molecular perturbation on cocrystal formation: theophylline and its 8‐halo analogues with flavonoids

open access: yesActa Crystallographica Section C, Volume 82, Issue 8, Page 414-426, August 2026.
The tendency for alkaloid–flavonoid cocrystal formation is found to be markedly different for theophylline (Tph) compared to its 8‐halo analogues. Through screening with 13 common flavonoids, Tph is found to form cocrystals with six flavonoids, whereas 8‐Cl‐Tph and 8‐Br‐Tph each form cocrystals with just two, myricetin and kaempferol.

Analytical and Clinical Performance of the Atellica HEMA 580 Haematology Analyzer: A Comparison With the ADVIA 2120i

open access: yesInternational Journal of Laboratory Hematology, Volume 48, Issue 4, Page 784-794, August 2026.
ABSTRACT Introduction The Atellica HEMA 580 is a novel haematology analyser providing eight‐part leukocyte differential and optical platelet (PLT) counting. We compared its analytical and clinical performance with that of the ADVIA 2120i. Methods A total of 796 residual whole blood specimens were analysed.

Effect of 5-Methylcytosine on the Stability of TripleStranded DNA - a Thermodynamic Study. Nuc. Acids Res

open access: yes, 1991
We have previously shown that the pyrimidine oligonucleotide 5'CTTCCTCCTCT (Y11) recognizes the double-helical stem of hairpin 5'GAAGGAGGAG-A-T4-TCTCCTCCTTC (h26) by triple-helix formation (1).

Analysis of Research Trends and Output Effectiveness in the Medical Field Based on the National Natural Science Foundation of China

open access: yesHealth Care Science, Volume 5, Issue 3, Page 231-239, June 2026.
The completion and output of NSFC‐funded medical projects reflect national strategic orientations and disciplinary development laws. It is suggested to establish a dynamic evaluation mechanism, promote the “basic research‐application‐transformation” collaborative model, support small‐scale yet high‐efficiency fields, and conduct long‐term tracking of ...
