A New Formulation for the Traveling Salesman Problem With Drone and Lockers
Networks, EarlyView.ABSTRACT Nowadays, driven by factors such as the rapid growth of online sales, different delivery methods are being explored to improve last‐mile logistics processes. Among these, the combined use of trucks and drones and the option of utilizing parcel lockers as an alternative to home delivery have led to the definition of new optimization problems ...

Quantum fractional revival governed by adjacency matrix Hamiltonian in unitary Cayley graphs [PDF]
arXivIn this article, we give characterization for existence of quantum fractional revival in unitary Cayley graph utilizing adjacency matrix Hamiltonian. Unitary Cayley graph $X=( Z_n, S)$ is a special graph as connection set $S \subseteq Z_n$ is the collection of coprimes to $n$.

General mechanisms for a top–down origin of the predator–prey power law
Oikos, EarlyView.The ratio of predator‐to‐prey biomass density is not constant along ecological gradients: denser ecosystems tend to have fewer predators per prey, following a scaling relation known as the ‘predator–prey power law'. The origin of this surprisingly general pattern, particularly its connection with environmental factors and predator–prey dynamics, is ...

Psychology in the Schools, EarlyView.ABSTRACT With the number of students classified as Dual Language Learners (DLLs) in U.S. schools consistently increasing, it is important for educators to consider academic interventions that include evidence‐based practices to support DLLs. Specifically in the field of mathematics, several strategies have been recommended to support DLLs' mathematical

Psychology in the Schools, EarlyView.ABSTRACT Despite the vital role of well‐being on academic achievement, doubts prevail as to what extent and how well‐being contributes to students' academic achievement. The present research therefore investigated the relation between well‐being and academic achievement using multidimensional measures, while considering self‐efficacy as a mediator ...

Modeling the Optical Efficiency of AlGaN/GaN Light Emission Diodes with 2D Carrier Localization
physica status solidi (a), EarlyView.A theoretical model is presented to describe the wavelength dependence of the optical efficiency of AlxGa1‐xN/AlN quantum wells and quantum dots emitting deep ultraviolet light between 210 and 310 nm. The model includes hole state symmetry changes, built‐in strain, quantum confinement, and electron–hole localization due to alloy disorder, treated as a ...
