Characterization and Optimization of Vesicle Properties in bioPISA: from Size Distribution to Post‐Assembly Loading

Advanced Biology, Volume 9, Issue 5, May 2025.
The paper explores the creation and characterization of vesicles through biocatalytic Polymerization‐Induced Self‐Assembly (bioPISA), focusing on achieving size uniformity using centrifugation techniques. It examines the effects of stirring speed on vesicle morphology and analyses the internal polymer‐rich structure using fluorescence correlation ...

A Survey of z~6 Quasars in the SDSS Deep Stripe. II. Discovery of Six Quasars at z_{AB}>21

, 2009
We present the discovery of six new quasars at z~6 selected from the Sloan Digital Sky Survey (SDSS) southern survey, a deep imaging survey obtained by repeatedly scanning a stripe along the celestial equator.

On the isoperimetric Riemannian Penrose inequality

Communications on Pure and Applied Mathematics, Volume 78, Issue 5, Page 1042-1085, May 2025.
Abstract We prove that the Riemannian Penrose inequality holds for asymptotically flat 3‐manifolds with nonnegative scalar curvature and connected horizon boundary, provided the optimal decay assumptions are met, which result in the ADM$\operatorname{ADM}$ mass being a well‐defined geometric invariant.

Spitzer Observations of 3C Quasars and Radio Galaxies: Mid-Infrared Properties of Powerful Radio Sources [PDF]

, 2006
We have measured mid-infrared radiation from an orientation-unbiased sample of 3CRR galaxies and quasars at redshifts 0.4 < z < 1.2 with the IRS and MIPS instruments on the Spitzer Space Telescope.

Characterization of an MR‐compatible motion platform for quality assurance of motion‐compensated treatments on the 1.5 T MR‐linac

Medical Physics, Volume 52, Issue 5, Page 3391-3397, May 2025.
Abstract Background Novel motion‐compensated treatment techniques on the MR‐linac can address adverse intra‐fraction motion effects. These techniques involve beam gating or intra‐fraction adaptations of the treatment plan based on real‐time magnetic resonance imaging (MRI) performed during treatment.

VODKA-JWST: Synchronized Growth of Two Supermassive Black Holes in a Massive Gas Disk? A 3.8 kpc Separation Dual Quasar at Cosmic Noon with the NIRSpec Integral Field Unit

The Astrophysical Journal
The search for dual supermassive black holes (SMBHs) is of immense interest in modern astrophysics. Galaxy mergers may fuel and produce SMBH pairs. Actively accreting SMBH pairs are observed as dual quasars, which are vital probes of SMBH growth.

Quantifying the dosimetric accuracy of expiration‐gated stereotactic lung radiotherapy

Medical Physics, Volume 52, Issue 5, Page 2773-2784, May 2025.
Abstract Background In stereotactic body radiotherapy, a form of motion management is often applied to mobile lung tumors. Gated radiotherapy is such form of motion management in which the radiation beam is switched on or off depending on the actual tumor position.

On the Fraction of X-ray Weak Quasars from the Sloan Digital Sky Survey [PDF]

arXiv, 2020
We investigate systematically the X-ray emission from type 1 quasars using a sample of 1825 Sloan Digital Sky Survey (SDSS) non-broad absorption line (non-BAL) quasars with Chandra archival observations. A significant correlation is found between the X-ray-to-optical power-law slope parameter ($\alpha_{\rm OX}$) and the 2500 $\r{A}$ monochromatic ...

Evolution of Eligibility Criteria in Inflammatory Bowel Disease Clinical Trials: A Clinical Trial Databank Analysis

United European Gastroenterology Journal, Volume 13, Issue 4, Page 542-551, May 2025.
ABSTRACT Background Eligibility criteria in clinical trials have been criticised for being overly restrictive without clinical justification. Objective We aimed to investigate the types, evolution, and current status of eligibility criteria in clinical trials for inflammatory bowel diseases (IBD).

Synchrotron macro‐ATR‐FTIR: a powerful technique for analyzing changes in plant cell chemical composition after surfactant exposure

The Plant Journal, Volume 122, Issue 4, May 2025.
Significance Statement Studies on how surfactants affect plant leaf surfaces mainly focus on droplet behavior, while their impact on leaf chemistry remains unclear. Using synchrotron macro‐ATR‐FTIR, we provide a fast and non‐destructive advanced method for leaf surface analysis and chemical mapping.
