International Endodontic Journal, EarlyView.ABSTRACT Introduction Apical periodontitis (AP) is an inflammatory disease of the periapical tissues driven by host responses to endodontic infection, and systemic metabolic disturbances, such as high‐fat diet (HFD)–induced dysmetabolism, may exacerbate tissue destruction. This study aimed to determine how chronic HFD exposure alters periapical myeloid

Reference‐Superimposed Reconstruction (RS‐Recon) for Arterial Spin Labeling
Magnetic Resonance in Medicine, Volume 96, Issue 6, Page 2685-2697, December 2026.ABSTRACT Purpose Conventional arterial spin labeling (ASL) reconstruction suffers from sign‐flipping errors and/or noise bias under strong background suppression (BS), limiting SNR optimization. We propose reference‐superimposed reconstruction (RS‐recon) to enable ideal BS and robust signal recovery.

Influence of Stiles-Crawford apodization on visual acuity
, 2002 The Stiles–Crawford effect (SCE) of the first kind has often been considered to be important to spatial visual performance in that it ameliorates the influence of defocus and aberrations.

Understanding higher‐order aberrations in keratoconus
Optometry and Vision Science, Volume 103, Issue 10, October 2026.ABSTRACT Keratoconus is characterized by progressive thinning and increasing irregularity of the cornea, leading to substantial degradation in optical quality through the induction of both lower‐ and higher‐order aberrations (HOAs). In addition to inducing myopic and astigmatic refractive error, asymmetric corneal steepening generates complex optical ...

Interferometric apodization of telescope apertures
, 2007 Aims.We seek to produce apodized apertures for application in stellar coronagraphy to help in direct detections of exoplanets. We show that chromatic apodized apertures of any shape in transmission can be obtained with a specific MZI and we demonstrate ...

Space‐Based Observation of Decadal Variations of Ammonium Sulfate Aerosols Over Northern China
Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.Abstract The concentrations of ammonium sulfate, an important component of secondary inorganic aerosols, have dropped substantially in the North China Plain (NCP) over the past decade. However, current understanding of its variations is limited by the small number of ground‐based measurement sites.
