On Some Algorithmic and Structural Results on Flames

open access: yesJournal of Graph Theory, EarlyView.
ABSTRACT A directed graph F $F$ with a root node r $r$ is called a flame if for every vertex v $v$ other than r $r$ the local edge‐connectivity value λF(r,v) ${\lambda }_{F}(r,v)$ from r $r$ to v $v$ is equal to ϱF(v) ${\varrho }_{F}(v)$, the in‐degree of v $v$.

Is acidification of common estuarine macroinvertebrates in stable isotope approaches necessary to analyze aquatic food webs?

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract We evaluated the effect of in situ acidification of common estuarine macroinvertebrates from the Elbe estuary on stable isotope ratios, as the non‐removal of non‐dietary carbon can significantly influence aquatic food web analyses. A 10% HCl solution was used to remove inorganic carbon from crustaceans, which potentially biases the true ratio ...

Tailoring Flatband Dispersion in Bilayer Moiré Photonic Crystals

open access: yesLaser &Photonics Reviews, EarlyView.
 The photonic dispersion in 1D moiré structures formed by stacking two photonic crystal slabs with slightly different periods is experimentally investigated. By precisely adjusting the filling factor of the photonic crystals, the evolution of moiré minibands into flatbands is experimentally and numerically demonstrated. This result provides a practical

Launch Uncertainty Analysis Under Barrel Erosion Using Experiments and Random Matrix Theory

open access: yesInternational Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT The effects of barrel erosion on artillery firing performance have long been a subject of concern, but its effect on launch uncertainty has yet to be investigated. This article explores the influence of barrel erosion on the interior ballistic mechanical properties and launch disturbances.

Abundant Neighborhoods, Two‐Sided Markets, and Maximal Matchings

open access: yesNaval Research Logistics (NRL), EarlyView.
ABSTRACT I introduce a new graph‐theoretic property called abundant neighborhoods. This property is motivated by studying the thickness of economic markets. A vertex is, roughly, guaranteed to match if and only if it has an abundant neighborhood.
