A Left and Right Truncated Schechter Luminosity Function for Quasars
Galaxies, 2017 The luminosity function for quasars (QSOs) is usually fitted by a Schechter function. The dependence of the number of quasars on the redshift, both in the low and high luminosity regions, requires the inclusion of a lower and upper boundary in the ...

Relativistic Beaming and the Nuclei of Double-lobed Radio Quasars [PDF]
Symposium - International Astronomical Union, 1988 We have defined a complete sample of double-lobed 3CR quasars with minimal orientation bias. Properties of these objects on the >kpc scale are consistent with the simple beaming model for their nuclei. VLBI maps of six nuclei reveal “core-jet” structures.

Quasars as Cosmological Standard Candles [PDF]
, 2017 We propose the use of quasars with accretion rate near the Eddington ratio (extreme quasars) as standard candles. The selection criteria are based on the Eigenvector 1 (E1) formalism. Our first sample is a selection of 334 optical quasar spectra from the

Ionized Gas Outflows from the MAGNUM Survey: NGC 1365 and NGC 4945
Frontiers in Astronomy and Space Sciences, 2017 AGN feedback, acting through strong outflows accelerated in the nuclear region of AGN hosts, is invoked as a key ingredient for galaxy evolution by many models to explain the observed BH-galaxy scaling relations.

Dynamic Regulation of Endogenous Transcription Factor Hubs at Single‐Molecule Resolution
Advanced Science, Volume 13, Issue 52, 18 September 2026.This study combines single‐molecule microscopy and genome editing to characterize the dynamic behaviors of endogenous oncofusion transcription factor EWS::FLI1 in Ewing sarcoma cells. EWS::FLI1 forms neomorphic hubs that dynamically assemble and dissolve. The hubs are regulated during mitosis, by RNA, and by specific chemicals.

Progress in Photovoltaics: Research and Applications, Volume 34, Issue 9, Page 1077-1099, September 2026.This study examines the reuse readiness of photovoltaic modules through the Swiss PV Circle project. Results confirm technical feasibility with cost savings from targeted preselection, whereas economic viability depends on module age, testing, and market conditions.

Characterization in stand-up comedy: From Ted Ray to Billy Connolly, via Bertolt Brecht [PDF]
, 2000 Stand-up comedy is often distinguished from straight acting by its apparent lack of characterization-the comedian appearing onstage apparently as him or herself.

UCHL3 Regulates Subgenomic Flaviviral RNA Condensates to Promote Virus Propagation
Advanced Science, Volume 13, Issue 48, 28 August 2026.ABSTRACT Flavivirus subgenomic RNAs (sfRNAs) antagonise antiviral defences, yet how sfRNAs are organized and maintained in cells remains poorly understood. Here we identify ubiquitin C‐terminal hydrolase L3 (UCHL3) as a post‐translational regulator of flavivirus sfRNA stability and function.

Scandinavian Journal of Medicine &Science in Sports, Volume 36, Issue 8, August 2026.ABSTRACT Cross‐sectional studies have indicated impaired neuromuscular and cortical activities following anterior cruciate ligament (ACL) reconstruction. However, adaptations throughout the recovery process remain unclear. Therefore, this study aimed to examine neuromuscular and cortical activity over the first year following ACL reconstruction.
