On the existence and multiplicity of solutions for nonlinear Klein–Gordon–Maxwell system
Electronic Journal of Qualitative Theory of Differential Equations, 2023 In this paper, we study the existence and multiplicity solutions for the following Klein–Gordon–Maxwell system \begin{align*} \begin{cases} - \Delta u +V(x)u-(2\omega+\phi)\phi u =f(x,u), &x\in \mathbb{R}^3,\\ \Delta \phi =(\omega+\phi)u^2, \quad &

Bayesian inference of a negative quantity from positive measurement results
, 2009 In this paper the Bayesian analysis is applied to assign a probability density to the value of a quantity having a definite sign. This analysis is logically consistent with the results, positive or negative, of repeated measurements.

Water Resources Research, Volume 61, Issue 2, February 2025.Abstract Active rock glaciers represent permafrost‐affected aquifers that store freshwater in alpine headwater catchments. Groundwater flow in these aquifers is altered by degrading permafrost and the development of preferential flow paths in the subsurface.

Cluster categories for completed infinity‐gons I: Categorifying triangulations
Journal of the London Mathematical Society, Volume 111, Issue 2, February 2025.Abstract Paquette and Yıldırım recently introduced triangulated categories of arcs in completed infinity‐gons, which are discs with an infinite closed set of marked points on their boundary. These categories have many features in common with the cluster categories associated to discs with different sets of marked points. In particular, they have (weak)

A Secure Approach for Caching Contents in Wireless Ad Hoc Networks
, 2017 Caching aims to store data locally in some nodes within the network to be able to retrieve the contents in shorter time periods. However, caching in the network did not always consider secure storage (due to the compromise between time performance and ...

Journal of Robotics, Volume 2025, Issue 1, 2025.Three‐dimensional map reconstructions provide representations of environments suitable for many robotics applications. However, the issue of scale error continues to hinder its practical applicability. This paper seeks to address this limitation by deploying advanced georegistration modalities integrated into the structure‐from‐motion (SfM) pipeline ...

Multiple Solutions for a Class of Fractional Schrödinger-Poisson System
Journal of Function Spaces, 2019 We investigate a class of fractional Schrödinger-Poisson system via variational methods. By using symmetric mountain pass theorem, we prove the existence of multiple solutions.

Multiple solutions for a self-consistent Dirac equation in two dimensions
, 2018 This paper is devoted to the variational study of an effective model for the electron transport in a graphene sample. We prove the existence of infinitely many stationary solutions for a nonlin-ear Dirac equation which appears in the WKB limit for the ...

Online fountain code with an improved caching mechanism
IET Communications, Volume 18, Issue 20, Page 1813-1825, December 2024.By catching some selected encoded symbols discarded in the original online fountain codes and giving an optimal degree selection strategy of encoded symbols, the proposed online fountain code improves the receiving rules of the encoded symbols. The proposed online codes outperform the state‐of‐art online fountain codes in terms of overhead factors ...
