On the Selection of High-z Quasars Using LOFAR Observations
Frontiers in Astronomy and Space Sciences, 2018 We present a method to identify candidate quasars which combines optical/infrared color selection with radio detections from the Low Frequency ARray (LOFAR) at 150MHz. We apply this {method} in a region of 9 square degrees located in the Bo\"{o}tes field,

Quasars at the redshift frontier (z > 7.0) are fundamental probes of black hole (BH) growth and evolution but notoriously difficult to identify. At these redshifts, machine learning-based selection methods have proven to be efficient, but require appropriate training sets to express their full potential.

Hypothalamic Astrocytes Exhibit Glycolytic Features Making Them Prone for Glucose Sensing
Glia, Volume 73, Issue 11, Page 2253-2272, November 2025.Main Points Hypothalamic astrocytes versus cortical astrocytes: are more glycolytic due to high Pkm2, Glut1 and Mct4 expression do not exhibit glutamate‐induced glycolysis detect glucose concentration variations via an AMPK sensor with altered lactate production.

Journal of Neuroimaging, Volume 35, Issue 6, November/December 2025.ABSTRACT Background and Purpose Individualized diagnostic approaches are crucial in cerebrovascular diseases, such as internal carotid artery stenosis (ICAS). To evaluate individual collateral blood supply, vessel‐selective imaging has gained high relevance.

Molecular Oncology, Volume 19, Issue 10, Page 2921-2935, October 2025.Combining melting curve analysis enhances the multiplexing capability of digital PCR. Here, we developed a 14‐plex assay to simultaneously measure single nucleotide mutations and amplifications of KRAS and GNAS, which are common driver genes in pancreatic cancer precursors. This assay accurately quantified variant allele frequencies in clinical samples

Chemistry &Biodiversity, Volume 22, Issue 10, October 2025.ABSTRACT Volatile secondary metabolites in plants can serve as valuable biomarkers for the plant's health, stress response, and pest or disease detection. We have investigated the volatilome of Acer saccharum (sugar maple) leaves using two complementary extraction techniques: headspace‐solid phase micro‐extraction coupled with gas chromatography‐mass ...
