Circum-Galactic Medium in the Halo of Quasars

open access: yesFrontiers in Astronomy and Space Sciences, 2017
The properties of circum-galactic gas in the halo of quasar host galaxies are investigated analyzing Mg II 2800 and C IV 1540 absorption-line systems along the line of sight close to quasars.

Posidonia oceanica Leaves as a Natural Filler for Poly(Butylene Succinate‐Co‐Adipate) Composites: Characterization and Biodegradation Assessment in Seawater

open access: yesJournal of Vinyl and Additive Technology, EarlyView.
This study shows that incorporating 5–10 wt.% Posidonia oceanica, with or without micro‐talc, in PBSA preserves thermal stability, modifying crystallization behavior, and maintains good filler dispersion and interfacial adhesion. Mechanical properties are moderately stiffened.

Predicting the Yields of z > 6.5 Quasar Surveys in the Era of Roman and Rubin

open access: yesThe 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,

The prognostic value of tumour budding for survival in stage II and III colorectal cancer: a systematic review and meta‐analysis

open access: yesHistopathology, EarlyView.
This meta‐analysis demonstrates that high‐grade tumour budding is an independent prognostic factor in stage II–III colorectal cancer, associated with significantly worse disease‐free survival, overall survival and cancer‐specific survival. Aims Tumour budding (TB) has been recognized as an additional prognostic factor in the TNM (2017) and WHO (2019 ...

Comprehensive Connection among the Quasars with Different Types of Outflow Absorption Lines

open access: yesThe Astrophysical Journal
It is commonly accepted that outflows from the central regions of quasars play a substantial role in regulating the global properties of the host galaxy. These outflows are typically detected through blueshifted absorption lines.

Asian Pacific Association of Gastroenterology (APAGE) Clinical Practice Guidelines on the Use of Small Molecules and IL‐23 p19 Inhibitors in Ulcerative Colitis and Crohn's Disease

open access: yesJournal of Gastroenterology and Hepatology, EarlyView.
ABSTRACT Ulcerative colitis (UC) and Crohn's disease (CD) are increasingly prevalent in the Asia Pacific region, necessitating updated, region‐specific guidance on advanced therapies. Targeted small molecule agents, such as filgotinib, tofacitinib, upadacitinib, etrasimod, and ozanimod; and the IL‐23 p19 inhibitors (guselkumab, mirikizumab ...

The Cosmic Ultraviolet Baryon Survey (CUBS). VIII. Group Environment of the Most Luminous Quasars at z ≈ 1

open access: yesThe Astrophysical Journal
We investigate the group-scale environment of 15 luminous quasars (luminosity L _3000 > 10 ^46 erg s ^−1 ) from the Cosmic Ultraviolet Baryon Survey (CUBS) at redshift z ≈ 1.

The effect of pre‐exercise hyperventilation on repeated high‐intensity inclined sprint performance

open access: yesExperimental Physiology, EarlyView.
Abstract High‐intensity exercise induces systemic acidosis, which contributes to muscular performance decline. Controlled pre‐exercise hyperventilation has been proposed as a non‐invasive intervention to induce respiratory alkalosis and counteract acidosis‐related acute fatigue.

Narrow [O iii] Emission Lines as a Potential Proxy for the Evolutionary Stage of Quasars

open access: yesThe Astrophysical Journal
Radio spectral shape of quasars can provide insight into the ages of quasars. We have compiled data for 1804 quasars with z ≲ 1 from the Sloan Digital Sky Survey (SDSS).

Feasibility of a field‐based submaximal stair ascent test for estimating aerobic capacity and lower‐limb strength in middle‐aged and older adults

open access: yesClinical Physiology and Functional Imaging, Volume 46, Issue 4, July 2026.
Abstract Background Assessing functional capacity is a key aspect of exercise testing and offers important insights into health in adult populations. However, accurate assessment often requires laboratory‐based maximal tests. This pilot study investigated whether a field‐based self‐paced submaximal stair ascent test could feasibly assess aerobic ...
