Existence of positive solutions in the superlinear case via coincidence degree: the Neumann and the periodic boundary value problems [PDF]
We prove the existence of positive periodic solutions for the second order nonlinear equation u'' + a(x) g(u) = 0, where g(u) has superlinear growth at zero and at infinity. The weight function a(x) is allowed to change its sign. Necessary and sufficient

In this paper, we investigate the existence of a set with 2kT $2kT$-periodic solutions for n-dimensional p-Laplacian neutral differential systems with a time-varying delay (φp(u(t)−Cu(t−τ))′)′+ddt∇F(u(t))+G(u(t−γ(t)))=ek(t) $(\varphi_{p}(u(t)-Cu(t-\tau ))

Time‐Dependent Oxidation and Scale Evolution of a Wrought Co/Ni‐Based Superalloy
This study shows how a new wrought Co/Ni‐based superalloy resists oxidation at 800 ∘$^\circ$C. The oxide scale changes from rough, fast‐growing spinel to a dense, protective chromia–alumina layer. Atom probe analysis reveals tiny refractory‐rich bubbles at the interface that mark the transition to long‐term, diffusion‐controlled protection ...

In this article, we discuss the existence of solutions to boundary-value problems for a coupled system of fractional differential equations with p-Laplacian operator at resonance. We prove the existence of solutions when $\dim \ker L\geq 2$, using the

Correlation between clinical diagnostics and necropsical findings
Background: the indices of discrepancy and coincidence of the causes of death between the clinical and morphological diagnosis constitute, indirectly, an indicator of the quality of medical care. Objective: to determine the relationship between clinical

Dirac–Bergmann analysis and degrees of freedom of coincident f(Q)-gravity
AbstractWe investigate the propagating degrees of freedom off(Q)-gravity in a 4-dimensional space-time under the imposition of the coincident gauge by performing the Dirac–Bergmann analysis. In this work, we start with a top-down reconstruction of the metric-affine gauge theory of gravity based only on the concept of a vector bundle.

Multimodal Data‐Driven Microstructure Characterization
A self‐consistent autonomous workflow for EBSP‐based microstructure segmentation by integrating PCA, GMM clustering, and cNMF with information‐theoretic parameter selection, requiring no user input. An optimal ROI size related to characteristic grain size is identified.

Coincidence matrix for E. coli Lsr system LMNAST stringent search hits. [PDF]
This coincidence matrix depicts the subset of hits with a mean element homology >0.3 and also containing 4–6 gene characters. This subset was chosen for its intermediate degree of homology to the query Lsr system.
