Primordial black holes through preheating instabilities in -attractor models
Daniel del-Corral, Paolo Gondolo, K. Sravan Kumar +2
The paper investigates how primordial black holes can form during the preheating phase after α‑attractor inflation, using instability criteria and comparing the Press‑Schechter and…
Robust Face Super-Resolution and Recognition Through Multi-Feature Aggregation in Diffusion Models
Marcelo dos Santos, Rayson Laroca, João Carlos Raposo Neves +1
Images acquired in surveillance environments often suffer from conditions such as low resolution, variations in pose, irregular illumination, and occlusions. Due to the low quality…
Emergent CDM cosmology from a measure-induced deformation of the Newtonian action
S. M. M. Rasouli
We propose a minimal extension of the Newtonian action by introducing a time-dependent fractional kernel characterized by a single deformation parameter . This kernel admits a…
Gravitational Foundations and Exact Solutions in -Dimensional Fractional Cosmology
S. M. M. Rasouli, J. Marto, D. A. V. Oliveira +1
Three theoretically plausible techniques to developing a fractional scalar field cosmological model are pointed in this paper; the time-dependent kernel weighted action being then…
Looking for the Bottleneck in Fine-grained Temporal Relation Classification
Hugo Sousa, Ricardo Campos, AlÃpio Jorge
Temporal relation classification is the task of determining the temporal relation between pairs of temporal entities in a text. Despite recent advancements in natural language proc…
