In aquaculture, the accurate recognition of fish underwater has outstanding academic value and economic benefits for scientifically guiding aquaculture production, which assists in analysis programs studies behavior. However, environment is complex affected by lighting, water quality, mutual obscuration bodies. Therefore, images are not very clear, restricts accuracy targets. This paper proposes an improved YOLO-V7 model identification Takifugu rubripes. Its specific implementation methods...

A bstract Within the so-called cosmological collider program, imprints of new particles on primordial non-Gaussianities have been studied intensively. In particular, their non- analytic features in soft limit provide a smoking gun for at inflation scale. While this approach is very powerful to probe mass near Hubble scale, signal exponentially suppressed heavy particles. paper, enlarge scope collider, we explore probing spins from signs Wilson coefficients inflaton effective action and...

In this work, we study the use of Bessel-Gauss beam launchers for wireless power transfer (WPT) applications. The efficiency between two radiating apertures is investigated in radiative near field. A spectral Green's function approach used to derive under a simultaneous conjugate impedance match. transverse electromagnetic (TEM) mode coaxial cable, as well Bessel (BB) and (BGB) field distributions, are considered aperture distributions. Numerical results demonstrate that BGB distribution...
A bstract Large excursion of the inflaton field can trigger interesting dynamics. One important example is a first-order phase transition in spectator sector which couples to inflaton. Gravitational waves (GWs) from such during inflation, an instantaneous source, have oscillatory feature. In this work, we show that feature generic for source era accelerated expansion. We also demonstrate shape GW signal contains information about evolution early universe following transition. particular,...

The contribution from massive propagator can be divided into local and non-local contributions. one leading power-law suppressed as a function mass, while exponentially in large mass limit. For contribution, it possible to use effective theory approach strongly coupled region parameter space. we developed partial method simplify calculation: when there are multiple propagators, fully compute...

The classification of elementary particles based on unitary irreducible representations the Poincare group has been a cornerstone modern Quantum Field Theory (QFT). While Standard Model (SM) does not inherently include Dark Matter (DM), any fundamental DM candidate should still conform to this or its extensions. Beyond standard representations, Wigner introduced class nontrivial states characterized by an additional discrete degree freedom, known as degeneracy. We systematically investigate...
Abstract Elko is a massive spin-half field of mass dimension one. differs from the Dirac and Majorana fermions because it furnishes irreducible representation extended Poincaré group with two-fold Wigner degeneracy where particle anti-particle states both have four degrees freedom. has renormalizable quartic self interaction which makes candidate for self-interacting dark matter. We study in spatially flat FLRW space-time find exact solutions de Sitter space. Furthermore, we its quantization...

Abstract We study the properties of gravitational wave (GW) signals produced by first-order phase transitions during inflation era. show that power spectrum a GW oscillates with its number. This signal can be observed directly future terrestrial and spatial detectors through B-mode in CMB. oscillatory feature is generic for any approximately instantaneous sources occurring distinct from after inflation. The details contain information about scale transition later evolution universe.
We study the effective field theory (EFT) description of virtual particle effects in quasi-single inflation, which unifies previous results on large mass and mixing cases. By using a horizon crossing approximation matching with known limits, approximate expressions for power spectrum spectral index are obtained.

Explorations of the violation null energy condition (NEC) in cosmology could enrich our understanding very early universe and related gravity theories. Although a fully stable NEC can be realized ``beyond Horndeski'' theory, it remains an open question whether is allowed by some fundamental properties UV-complete theories or consistency requirements effective field theory (EFT). We investigate tree-level perturbative unitarity for violations contexts both Galileon genesis cosmology, which...
