Polyamide Acid–Based Surface Modification of Poly(p‐Phenylene Benzobisoxazole) Fibres Reinforcing Syntactic Foam for Using Them as High‐Performance Insulating Core Material

open access: yesHigh Voltage, EarlyView.
ABSTRACT The insulating core is an important part of pillar composite insulators used in power transmission systems. Traditional insulating core materials suffer from various problems that can threaten the reliability of insulated equipment. Syntactic foam (SF) exhibits excellent properties, such as a low density, water penetration resistance and high ...

Demographic buffering in natural populations: A multi‐level perspective

open access: yesJournal of Animal Ecology, EarlyView.
We introduce a multi‐level framework that unites stochastic elasticities with nonlinear selection to test demographic buffering. Applying it across mammals reveals a key insight: ecological robustness to variability often decouples from evolutionary constraint, reshaping how we understand resilience under environmental stochasticity.

Fronting in Old Catalan: Asymmetries between Narration and Reported Speech1

open access: yesTransactions of the Philological Society, Volume 123, Issue 1, Page 1-28, March 2025.
Abstract This article explores the distribution, syntax, and information structure of XVS clauses in the narrative text and the reported speech of a thirteenth‐century Old Catalan chronicle, the Llibre dels Fets. It is shown that XVS occurs mainly within reported speech and in embedded clauses.

Misconduct complaints and agents’ incentives: Evidence from housing transactions

open access: yesReal Estate Economics, EarlyView.
Abstract This article investigates the impact of misconduct complaints against agents on their self‐interested incentives and examines how agents attempt to shield themselves from the associated adverse effects on their reputations and career prospects.

“Alien versus predator”: predatory effect of coccinellid Exochomus quadripustulatus on the scale insect Toumeyella parvicornis. An open‐field experimentation on the Pinus pinea of Rome

open access: yesInsect Science, EarlyView.
The release of gravid Exochomus quadripustulatus females proved to be effective in containing Toumeyella parvicornis infestations on stone pine trees, under open‐field condition. The ladybugs caused a lower infestation level compared to the trees that did not receive any ladybugs during the observation season.

Pre-Outburst Signal in the Light Curves of the Recurrent Novae RS Oph and T CrB

Bulgarian Journal of Physics, 2023
Pre-outburst signal (a decrease of the optical brightness) just before the outburst is clearly detected in the observations of the T CrB obtained before and during the 1946 outburst.

A Recurrent Nova

Nature, 1946
ON-February 10 the variable star T Coronae Borealis, normally of magnitude 9, was seen to have blazed up to magnitude 3. This star had a typical nova outburst in 1866, when it was the first nova to be examined spectroscopically. Unlike other novae, its spectrum after fading was of late type with strong absorption bands of titanium oxide.

Identification of recurrent novae from parametric modeling of the optical light curve

Advances in Space Research
Novae, characterized by sudden brightening in binary star systems, are categorized into classical novae (CNe) and recurrent novae (RNe) based on their recurrence timescales.
