Impulse oscillometry for detection of small airway dysfunction in subjects with chronic respiratory symptoms and preserved pulmonary function

open access: yesRespiratory Research, 2021
Background Subjects with chronic respiratory symptoms and preserved pulmonary function (PPF) may have small airway dysfunction (SAD). As the most common means to detect SAD, spirometry needs good cooperation and its reliability is controversial.

Greybody factor for the BTZ black hole and a 5D black hole

open access: yes, 1998
We study the 5D black holes in the type IIB superstring theory compactified on $S^1 \times T^4$. Far from horizon, we have flat space-time. Near horizon, we have $AdS_3(BTZ black hole) \times S^3 \times T^4$.

Quasilocal energy for rotating charged black hole solutions in general relativity and string theory [PDF]

open access: yes, 1999
We explore the (non)-universality of Martinez's conjecture, originally proposed for Kerr black holes, within and beyond general relativity. The conjecture states that the Brown-York quasilocal energy at the outer horizon of such a black hole reduces to ...

Scaffolding during surgical procedures: Guidance with baby steps or giant leaps?

open access: yesMedical Education, EarlyView.
Abstract Introduction Scaffolding refers to the dynamic support teachers provide to help learners complete tasks they cannot yet do independently. This is often done by breaking tasks into smaller, manageable steps and adjusting the support based on the learner's performance.

Effects of the antiozonant ethylenediurea (EDU) on Fraxinus ornus L.. The role of drought [PDF]

open access: yes, 2017
Ethylenediurea (EDU) is a synthetic chemical known to protect plants from the phytotoxic effects of tropospheric ozone (O3). Although many studies have proposed the use of EDU for studying the O3 effects under field conditions, its mechanism of action is

Navigating Academic Integrity in Doctoral Education: A Study of Misconduct in Doctoral Defence Practices in Mongolia

open access: yesHigher Education Quarterly, Volume 80, Issue 2, April 2026.
ABSTRACT Doctoral defences play a critical role in safeguarding the integrity and credibility of doctoral education. In Mongolia, however, defence practices, administered through centralised committees rooted in Soviet academic traditions, face significant structural, cultural, and ethical challenges.

The Effect of Stress Singularities in the Failure of Composite Off‐Axis Specimens Subjected to Tension

open access: yesPolymer Composites, Volume 47, Issue 3, Page 2726-2739, 10 February 2026.
Premature failures at the tab of the off‐axis tension test, motivated by the presence of the stress singularity. ABSTRACT This work is motivated by the observation of premature failures in off‐axis tension test specimens for the characterization of intralaminar shear strength in unidirectional composite materials.
