Archaeological Prospection, EarlyView.ABSTRACT High‐resolution and accurate synoptic images of terrestrial topography, even in densely forested areas, have proven valuable for archaeology by enabling the identification and characterization of relief patterns associated with ancient human activities. This study presents a novel approach that integrates digital terrain models (DTMs) obtained

Fractional Hermite–Hadamard type inequalities for interval-valued functions
Journal of Inequalities and Applications, 2019 We introduce the concept of interval harmonically convex functions. By using two different classes of convexity, we get some further refinements for interval fractional Hermite–Hadamard type inequalities. Also, some examples are presented.

Front Propagation Through a Perforated Wall
Communications on Pure and Applied Mathematics, EarlyView.ABSTRACT We consider a bistable reaction– diffusion equation ut=Δu+f(u)$u_t=\Delta u +f(u)$ on RN${\mathbb {R}}^N$ in the presence of an obstacle K$K$, which is a wall of infinite span with many holes. More precisely, K$K$ is a closed subset of RN${\mathbb {R}}^N$ with smooth boundary such that its projection onto the x1$x_1$‐axis is bounded and that ...

Compact Manifolds With Unbounded Nilpotent Fundamental Groups and Positive Ricci Curvature
Communications on Pure and Applied Mathematics, EarlyView.ABSTRACT It follows from the work of Kapovitch and Wilking that a closed manifold with nonnegative Ricci curvature has a uniformly almost nilpotent fundamental group. Leftover questions and conjectures, have asked if in this context the fundamental group is actually uniformly almost abelian. The main goal of this work is to construct examples (Mk9,gk)$(

On a Subclass of Harmonic Close-to-Convex Functions Generated by the Harmonic Error Function
Mathematical Sciences and Applications E-NotesWe introduce a new subclass $\Xi P_{H}^{0}(\lambda)$ of harmonic mappings in the unit disk defined via a differential inequality involving the convolution operator generated by the harmonic error function. We show that this inequality directly produces harmonic close-to-convex mappings of order $\lambda$, thereby establishing a structural connection ...

Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT Viscous dampers (VDs) are widely used to mitigate the excessive responses of long‐span bridges. However, VDs face some intricate challenges in engineering practices, including high damping coefficient requirement, potential base shear amplification and tremendous damping force under high velocity. To address these issues, this study develops a

Coherent Stokes Raman Scattering for Simultaneous Measurement of CO2 and CH4 Temperatures
Journal of Raman Spectroscopy, EarlyView.A three‐beam hybrid fs/ps CSRS method is employed to excite the rovibrational transitions in the Fermi‐dyad of CO2$$ {}_2 $$ and the v2$$ {v}_2 $$ mode of CH4$$ {}_4 $$. Time‐domain spectroscopic models are developed to extract the fuel and flame temperature profiles from experimental CH4$$ {}_4 $$ and CO2$$ {}_2 $$ spectra in a diffusion flame ...

On Convexity of Level Curves of Harmonic Functions in the Hyperbolic Plane [PDF]
Proceedings of the American Mathematical Society, 1992 We prove that if two level curves of a harmonic function are convex in the hyperbolic disc then all intermediate level curves are also convex.
