Abstract The principal one-particle operators of quantum theory of Proca’s free field are derived using a method associating to any operator in a configuration representation a pair of operators acting directly on part...

The study of the heat-trace expansion in non-commutative field theory has shown the existence of Moyal non-local Seeley?DeWitt coefficients which are related to the UV/IR mixing and manifest, in some cases, the non-renor...

Abstract We consider application of the analytic functional approach to the conformal field theories associated with mean field theory and Wilson–Fisher fixed point. We study the constraints imposed by the crossing sym...

Abstract This work generalizes Heider’s classical balance theory into a quantum mechanical framework. The core idea is that, just as quantum reality exists in a superposition of possibilities until observed, our real-l...

Abstract Finding a complete and yet minimal on-shell basis of operators of a given mass-dimension that are compatible with a specific set of transformation properties is the first step in any Effective Field Theory descr...

We obtain, using semianalytical transfer operator techniques, the Edwards thermodynamics of a one-dimensional model of blocks connected by harmonic springs and subjected to dry friction. The theory is able to reproduce t...

Ride-pooling has the potential to offer a sustainable solution for urban mobility by reducing vehicle use and emissions through shared trips. However, its adoption remains limited due to poor matching performance. Many r...

We compute the contact term of the two-point function for the SL (2, ℝ)- WZNW model in the winding sector. After reviewing some generalities of the model and its Euclidean counterpart, we discuss the reflection symmetr...

In this paper, we develop a systematic framework for studying fixed-point theory in the setting of normed GE-algebras. Building on the GE-norm, we introduce and analyze nonexpansive mappings, α-averaged mappings, and en...

Abstract This study evaluates the effectiveness of a gamified interactive educational tool (G-IET) in addressing reversal errors in algebra, a persistent misinterpretation of relational language in comparative word probl...

The discontinuities distributed in underground structures are the important factors that affect the mechanical characteristics of rock mass, and to study the mechanical behavior of rock discontinuities under cyclic loadi...

In this paper, the Servicescape theory was employed as the conceptual framework to (a) investigate the live airport experiences of passengers with an HD and (b) understand the negative experiences of passengers within th...

Abstract This paper reports the observation of electroweak diboson (WW/WZ/ZZ) production in association with a high-mass dijet system, in which final states with one boson decaying leptonically and the other boson decayi...

Abstract The ability to monitor the safety of natural gas pipelines is guaranteed by leak detection. Systems are capable of responding quickly, and very precisely to events because delays during such events can lead to s...

Abstract We derive the asymptotic lattice-spacing dependence $$a^2[2b_0\bar{g}^2(1/a)]^{\hat{\gamma }_i}$$ a 2 [ 2 b 0 g ¯ 2 ( 1 / a ) ] γ ^ i relevant for spectral quantities of lattice QCD, when using unrooted Stagge...

Penelitian ini mengkaji tentang jenis penyandang disabilitas dan bentuk pemberdayaan penyandang disabilitas pada objek wisata Kuta, Kabupaten Badung, Provinsi Bali. Masalah ini dianalisis secara kualitatif dengan pendeka...

Abstract This study investigates the diffusion of new energy technology among the water sightseeing transportation industry driven by the low-carbon behavior of tourists, particularly focusing on the influential role of ...

A theory of superconductivity is presented, based on the fact that the interaction between electrons resulting from virtual exchange of phonons is attractive when the energy difference between the electrons states involv...

In this article we will introduce certain considerations that must be taken into account while implementing the change operations of the belief change theory. The abstract models of bellief change make no considerations ...

Multiresolution representations are effective for analyzing the information content of images. The properties of the operator which approximates a signal at a given resolution were studied. It is shown that the differenc...

Multi-objective evolutionary algorithms (MOEAs) that use non-dominated sorting and sharing have been criticized mainly for: (1) their O(MN/sup 3/) computational complexity (where M is the number of objectives and N is th...

The formal relationship between ultrasoft (US) Vanderbilt-type pseudopotentials and Bl\"ochl's projector augmented wave (PAW) method is derived. It is shown that the total energy functional for US pseudopotentials can be...

El artículo pretende, en primer lugar, caracterizar brevemente la idea de verdad necesaria en Leibniz a los efectos de mostrar cómo en el desarrollo de las investigaciones lógicas ella se ha ido debilitando al extremo...

Recently, it has been proposed by Maldacena that large N limits of certain conformal field theories in d dimensions can be described in terms of supergravity (and string theory) on the product of d 4-1dimensional AdS spa...
