Fruit use and fruit processing by euphonias, specialized avian frugivores

Oikos, EarlyView.
Euphonias (Neotropical passerines in the genera Euphonia and Chlorophonia) form the quintessential example of a specialized avian frugivore, combining a high reliance on fruit as food and the restriction of fruit taxa exploited. To understand their specialization, we explored the integration of fruit morphological and nutritional traits with their ...

Weak-Basis Invariants and Cp Violation

, 1999
Abstract In the previous two chapters we have taken the usual path to CP violation in the SM. We have bi-diagonalized the quark mass matrices and noticed the appearance of a mixing matrix V in the charged-current interaction. We saw that, for three or more fermion generations, some of the phases in V cannot be removed by rephasing the ...

The Path to Neutrality: Evaluating Carbon Offsetting Strategies Among Spanish Corporations

Sustainable Development, EarlyView.
ABSTRACT This study examines how offset project characteristics and financial conditions shape the intensity of corporate carbon offsetting in voluntary carbon markets (VCMs). Focusing on a Southern European context, the analysis draws on a longitudinal panel of 357 Spanish firms observed between 2019 and 2022.

Identifying CP Basis Invariants in SMEFT

Building on our automated framework that uses ring diagrams for classifying CP basis invariants [Phys. Rev. D 108, 115030 (2023)], this paper broadens the application of the methodology with more extensive examples and a wider scope of theoretical frameworks.

Linking Pulse‐Duration‐Controlled Laser Nanostructuring to Oxygen Evolution Kinetics in Fe‐enriched NiOx Electrodes

Small, EarlyView.
Pulse‐duration‐controlled ultra‐short laser processing is shown to directly create binder‐free Fe‐enriched NiOx electrodes with tunable porosity, active‐site density, and oxygen‐evolution kinetics. Shorter pulses generate defect‐rich nanostructures that accelerate charge transfer, promote highly active NiFeOOH formation, and deliver durable alkaline ...

Discrete symmetries tested at 10−4 precision using linear polarization of photons from positronium annihilations

Nature Communications
Discrete symmetries play an important role in particle physics with violation of CP connected to the matter-antimatter imbalance in the Universe. We report the most precise test of P, T and CP invariance in decays of ortho-positronium, performed with ...

Investigating Breathing Dynamics of a 110 kV Oil‐Immersed Transformer Using Thermal‐Fluid‐Structure Interaction Modelling

High Voltage, EarlyView.
ABSTRACT The breathing system of an oil‐immersed transformer is of vital importance for maintaining equilibrium between internal and external pressures, with any malfunction potentially disrupting the transformer's stable operation. This study develops a thermal–fluid–structure interaction (TFSI) model to simulate the breathing phenomenon in a 110 kV ...

Dynamic Modal‐Based Vibration Characteristics Analysis and Looseness Fault Diagnosis in Transformer Winding

High Voltage, EarlyView.
ABSTRACT Limited by the theoretical basis and diagnostic methods, the winding mechanical condition monitoring often requires both normal condition vibration signals and present vibration signals, and the winding mechanical condition identification is completed by comparing with the normal condition signals.

Fronting in Old Catalan: Asymmetries between Narration and Reported Speech1

Transactions 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.

Radiative mass mechanism: addressing the flavour hierarchy and strong CP puzzle

Journal of High Energy Physics
We propose a class of models based on the parity invariant Left-Right Symmetric Model (LRSM), which incorporates the mechanism of radiative generation of fermion masses while simultaneously possessing the solution to the Strong CP problem.
