AUTOMATIC DETECTION AND CHARACTERISATION OF POWER LINES AND THEIR SURROUNDINGS USING LIDAR DATA [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2019
Light Detection and Ranging (LiDAR) is nowadays one of the most used tools to obtain geospatial data. In this paper, a method to detect and characterise power lines of both high and low voltage and their surroundings from 3D LiDAR point clouds ...

Singular Continuous Spectrum for Singular Potentials [PDF]

open access: yesCommunications in Mathematical Physics, 2017
We prove that Schrödinger operators with meromorphic potentials $(H_{α,θ}u)_n=u_{n+1}+u_{n-1}+ \frac{g(θ+nα)}{f(θ+nα)} u_n$ have purely singular continuous spectrum on the set $\{E: L(E)

Screw sense excess and reversals of helical polymers in solution

open access: yesNature Communications, 2023
Reversals are structural motifs found in helical polymers that are difficult to determine experimentally. Here, the authors turn to photochemical electrocyclization as a tool to establish their presence and estimate excess screw sense in solution.

A Swarming Approach for the Novel Second Order Perturbed Pantograph Lane–Emden Model Arising in Astrophysics

open access: yesAxioms, 2022
The purpose of this study is to provide a mathematical construction based on the novel singular perturbed model of the second kind (NSPM-SK) using the standard form of the Lane–Emden. The singular Lane–Emden types of the models have abundant applications

Biomimetic cell-derived nanocarriers in cancer research

open access: yesJournal of Nanobiotechnology, 2022
Nanoparticles have now long demonstrated capabilities that make them attractive to use in biology and medicine. Some of them, such as lipid nanoparticles (SARS-CoV-2 vaccines) or metallic nanoparticles (contrast agents) are already approved for their use

Benchmarking of FinFET, Nanosheet, and Nanowire FET Architectures for Future Technology Nodes

open access: yesIEEE Access, 2020
Nanosheet (NS) and nanowire (NW) FET architectures scaled to a gate length (LG) of 16 nm and below are benchmarked against equivalent FinFETs. The device performance is predicted using a 3D finite element drift-diffusion/Monte Carlo simulation toolbox ...

La “carencia de límites de lo conceptual” y los pensamientos singulares en McDowell

open access: yesRevista Filosofía UIS, 2021
En este trabajo se analiza la propuesta en torno de los pensamientos singulares o “pensamientos de re” del filósofo contemporáneo John McDowell. Nuestra estrategia es abordar dicha reconstrucción a partir de la tesis de “la carencia de límites de lo ...

Wandering singularities [PDF]

open access: yesJournal of Differential Geometry, 2021
Parabolic geometric flows are smoothing for short time however, over long time, singularities are typically unavoidable, can be very nasty and may be impossible to classify. The idea of [CM6] and here is that, by bringing in the dynamical properties of the flow, we obtain also smoothing for large time for generic initial conditions. When combined with [
