Dust emission from quasars and quasar host galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 1999 We test emission models of circum-nuclear dust torii around quasars, at low and high redshifts, by using a large collection of photometric data for an unbiased sample of 120 optically-selected objects with millimetric and sub-millimetric fluxes, including new unpublished data.

Formation of Condition‐Dependent Alpha‐Synuclein Fibril Strain in Artificial Cerebrospinal Fluid
Advanced Science, Volume 13, Issue 7, 3 February 2026.α‐synuclein aggregation in artificial cerebrospinal fluid (aCSF) leads to a distinct conformation with an electron density pocket motif found in aggregates from PD and MSA patients. Such fibrils has low stability outside the reaction conditions, hinting about the influence of cerebrospinal fluid components not only on the formation, but also on the ...

An overview on the quasar redshifts
Revista Técnica de la Facultad de Ingeniería, 2011 An overview of the foundations of modem cosmology a well as the controversies about physical association between high-red shift quasi-stellar objects and low-red shift galaxies are presented. This kind of evidence challenges the current velocity-distance

Quasars Probing Quasars. II. The Anisotropic Clustering of Optically Thick Absorbers around Quasars [PDF]
The Astrophysical Journal, 2007 With close pairs of quasars at different redshifts, a background quasar sightline can be used to study a foreground quasar's environment in absorption. We used a sample of 17 Lyman limit systems with column density N_HI > 10^19 cm^-2 selected from 149 projected quasar pair sightlines, to investigate the clustering pattern of optically thick ...

Epstein‐Barr Virus Expressed Long Non‐Coding RNA (lncBARTs) Regulate EBV Latent Genome Replication
Advanced Science, Volume 13, Issue 8, 9 February 2026.EBV produces abundant level of lncBARTs, which are essential for maintaining viral genome replication in EBV‐associated cancers. LncBARTs interact with a complex comprising BRD4, CTCF and viral protein EBNA1 at EBV oriP region. This interaction tethers oriP to host chromosomes, facilitating EBV episome replication.

Overcoming PEG Antigenicity: Statistical PEG Isomers Reduce Antibody Binding
Advanced Science, Volume 13, Issue 7, 3 February 2026.Conventional poly(ethylene glycol) (PEG) is commonly applied in biomedicine, but is now known to induce antibody formation. Here, it is shown that the development of “randomized PEG” (rPEG) featuring glycidyl methyl ether (GME) comonomers decreased antibody binding.
