Observation of Linear and Nonlinear Light Trapping on Topological Dislocations

Laser &Photonics Reviews, EarlyView.
Topological dislocations are global lattice defects found in various systems ranging from crystals to photonic lattices. This work reports the first observation at optical frequencies of linear modes with tunable localization bound to edge dislocations and their nonlinear counterparts ‐ dislocation solitons. These results reveal an intriguing interplay

Physico‐Chemical Understanding of Plasticizers Interaction with P(VDF‐TrFE‐CFE) Electroactive Polymer

Macromolecular Materials and Engineering, EarlyView.
This study explores the effects of DNOP plasticizer on P(VDF‐TrFE‐CFE) terpolymers, revealing a strong synergy between chemical structure and physical properties. High TrFE bringing natural flexibility and CFE enhancing the plasticizer retention through theorized halogen bonds, ultra‐soft, crack‐free films of high permittivity and softness are ...

Voice and Speech in Atypical Parkinsonian Disorders

Movement Disorders Clinical Practice, EarlyView.
Background Motor speech disorders are early, common, and functionally limiting features of atypical parkinsonian disorders (APDs) such as progressive supranuclear palsy (PSP), corticobasal syndrome (CBS), and multiple system atrophy (MSA). These impairments are underrecognized and undertreated in neurology clinics.

When species are lost but functions persist: a trait‐based perspective on Wadden Sea bird diversity dynamics

Oikos, EarlyView.
Biodiversity faces several global threats and communities are likely to show complex delayed responses. Accurately measuring these lags is critical to properly understand diversity dynamics. Here, we investigated these delays with minimal data availability and found critical mismatches between the temporal dynamics of taxonomic and functional diversity

Trap‐dependence in capture–recapture studies: empirical evidence in vertebrates and biological meaning

Oikos, EarlyView.
Capture–recapture (CR) models have been used for decades to estimate population size and demographic rates in natural populations from the monitoring of individuals. One of the most frequent deviations from assumptions required in CR studies is the immediate trap‐dependence that corresponds to the correlation between capture events. We review empirical
