Meander‐Bend Erosion Dynamics Along a Gravel‐Bed River: Insights From Short‐Term UAV Monitoring
River Research and Applications, EarlyView.ABSTRACT Riverbank erosion is a natural process in meandering rivers that contributes to sediment supply and geomorphic diversity, yet it can threaten infrastructure and human activities within the floodplain. Recently, many studies have used high‐resolution remote sensing technologies to measure bank erosion, but they often focus on technical aspects ...

Geodesic complexity for non-geodesic spaces
, 2020 We define the notion of near geodesic between points of a metric space when no geodesic exists, and use this to extend Recio-Mitter\u27s notion of geodesic complexity to non-geodesic spaces. This has potential application to topological robotics.

European Physical Journal C: Particles and FieldsThermodynamic geometry allow us to study the microscopic behavior of black hole system by defining a metric structure in thermodynamic phase space. Among the various thermodynamic metric structures, metrics defined by geometrothermodynamics (GTD) are ...

Strongly contracting geodesics in Outer Space [PDF]
Geometry & Topology, 2011 We study the Lipschitz metric on Outer Space and prove that fully irreducible elements of Out(F_n) act by hyperbolic isometries with axes which are strongly contracting. As a corollary, we prove that the axes of fully irreducible automorphisms in the Cayley graph of Out(F_n) are stable, meaning that a quasi-geodesic with endpoints on the axis stays ...

Remote Sensing in Ecology and Conservation, EarlyView.The single‐scan approach to terrestrial laser scanning (TLS) and the self‐terrain‐normalized form of drone‐based digital aerial photogrammetry (DAP) offer practical options for rapid assessment of the vegetation structure in tropical landscapes.

Sustainable Development, EarlyView.ABSTRACT This study examines the interplay between climate change, violent conflict and forced migration in the Middle East and North Africa (MENA), focusing on asylum flows to the European Union (EU). By integrating high‐resolution climate, conflict and socioeconomic data spanning 2000 to 2023, we develop a comprehensive empirical framework to ...

Totally geodesic subvarieties in the moduli space of Riemann surfaces
, 2016 We will present an algebraic surface in the moduli space of triply punctured tori with the remarkable property that it is totally geodesic for Teichmuller metric. Our example reveals a surprising connection between Teichmuller theory and the geometry of

Level Set Gait Analysis for Synthesis and Reconstruction
, 2009 We describe a new technique to extract the boundary of a walking subject, with ability to predict movement in missing frames. This paper uses a level sets representation of the training shapes and uses an interpolating cubic spline to model the ...

A new smooth failure criterion for concrete inspired by Lubliner's condition
Structural Concrete, EarlyView.Abstract A new failure criterion with 10 parameters is proposed, based on Lubliner's idea of joining two Drucker–Prager cones. The novelty lies in the way of introducing deviatoric shape variation: through two Podgórski's functions. This feature allows for improving plane stress cross‐section's compatibility with experimental data.

Strolling along gauge theory vacua
Journal of High Energy Physics, 2017 We consider classical, pure Yang-Mills theory in a box. We show how a set of static electric fields that solve the theory in an adiabatic limit correspond to geodesic motion on the space of vacua, equipped with a particular Riemannian metric that we ...
