Quasars and their host galaxies [PDF]
, 2006 This review attempts to describe developments in the fields of quasar and quasar host galaxies in the past five. In this time period, the Sloan and 2dF quasar surveys have added several tens of thousands of quasars, with Sloan quasars being found to z>6.

Predicting the Yields of z > 6.5 Quasar Surveys in the Era of Roman and Rubin [PDF]
The Astrophysical Journal, 2023 About 70 luminous quasars discovered at z > 6.5 are strongly biased toward the bright end, thus not providing a comprehensive view of quasar abundance beyond the cosmic dawn. We present the predicted results of the Roman/Rubin high-redshift quasar survey,

On the link between associated MgII absorbers and star formation in quasar hosts [PDF]
, 2012 A few percent of quasars show strong associated MgII absorption, with velocities (v_off) lying within a few thousand km/s from the quasar systemic redshift.

AI-driven remote sensing enhances Mediterranean seagrass monitoring and conservation to combat climate change and anthropogenic impacts [PDF]
Scientific ReportsSeagrasses are undergoing widespread loss due to anthropogenic pressure and climate change. Since 1960, the Mediterranean seascape lost 13–50% of the areal extent of its dominant and endemic seagrass-Posidonia oceanica, which regulates its ecosystem ...

Pharmacogenetic-guided dosing for fluoropyrimidine (DPYD) and irinotecan (UGT1A1*28) chemotherapies for patients with cancer (PACIFIC-PGx): A multicenter clinical trial. [PDF]
Clin Transl SciAbstract PACIFIC‐PGx evaluated the feasibility of implementing pharmacogenetics (PGx) screening in Australia and the impact of DPYD/UGT1A1 genotype‐guided dosing on severe fluoropyrimidine (FP) and irinotecan‐related toxicities and hospitalizations, compared to historical controls.

Spectral Classification of Quasar Subject to Redshift: A Statistical Study
Computer Sciences & Mathematics Forum, 2023 Quasars are astronomical star-like objects having a large ultraviolet flux of radiation accompanied by generally broad emission lines and absorption lines in some cases found at large redshift. The used data is extracted from the Veron Cetti Catalogue of
