The tension between direct measurements of the Hubble constant and those stemming from Cosmic Microwave Background probes has triggered a multitude of studies. The connection between cosmology and particle physics has shown to be a valuable approach

We investigate primordial magnetogenesis within a quantum bouncing model driven by a scalar field, focusing on various non-minimal couplings between the electromagnetic field and the scalar field. We test three cases: no coupling, a Cauchy coupling w

The aim of this study was to evaluate the synchronization rate, ease to parturition, calves viability and retained placenta rate for Nellore recipients treated with triancinolone (TRI) + dexametasone (DEXA) + PGF2α (d-CLO). Hundred-ninety-four cross

It was evaluated in ovine semen pool, different cooling times (C) pre-freezing on the motility (M) and the sperm vigor (V) after thawing and TRT (Thermo Resistance Test). Four Santa Inês sheep were submitted to semen collections in nine replicates.

The bovine female pass critical moments between one parturition and another, the transition period being one of them. The transition period is characterized by a three-week interval before and after delivery, where significant metabolic changes are o

We have witnessed different values of the Hubble constant being found in the literature in the past years. Albeit, early measurements often result in an $H_0$ much smaller than those from late-time ones, producing a statistically significant discrepa

We consider a k-essence model in which a single scalar field can be responsible for both primordial inflation and the present observed acceleration of the cosmological background geometry, while also admitting a nonsingular de Sitter beginning of the

A very simple non-singular inflationary model is presented where the unique matter content is a radiation fluid. The model slowly contracts from a very large, almost empty and flat spacetime and realizes a bounce. It is then launched to a quasi-de Si

We investigate the Minkowski ground state associated with a real massless scalar field as seen by an accelerated observer under the perspective of the de Broglie-Bohm quantum theory. We use the Schr\"odinger picture to obtain the wave functional asso

This study investigates the cognitive mechanisms underlying vigilance and pattern recognition using a novel adaptation of Mackworth’s Clock Test. We aimed to quantify the time it takes for temporal patterns detected unconsciously through implicit l
