A Yup'ik dance mask from the early‐1900s connects Indigenous tradition and shorebird conservation
People and Nature, EarlyView.Abstract A dance mask from the early 1900s reveals connections between Yup'ik people of western Alaska and shorebirds as well as their shared struggle to thrive in the modern world. As a masterpiece of Yup'ik art, the shorebird mask was embraced by the French Surrealism (musée du quai Branly‐Jacques Chirac 70.2006.41.1, Museum of the American Indian 9 ...

Hybrid Nanoparticles Separated by Buoyant Density in a Large‐Scale Centrifugal Process
Journal of Polymer Science, EarlyView.Zonal rotors, shaped like hollow bowls, can sort mixtures of macromolecules and polymer nanoparticles based only on their densities, regardless of their actual sizes or shapes. Using these rotors can make a big difference because they do not need to use centrifuge tubes.

Fortschritte der Physik, EarlyView.Abstract The unification of conformal and fuzzy gravities with internal interactions is based on the facts that i) the tangent group of a curved manifold and the manifold itself do not necessarily have the same dimensions and ii) both gravitational theories considered here have been formulated in a gauge theoretic way.

, 2012 The Graceful Tree Conjecture was published almost 40 years ago and nowadays it is still an open problem. It seems as difficult to solve as it is to enunciate: every tree admits a vertex labeling on 0, 1, ..., n-1 such that the set of values of the differences of the numbers assigned to the ends of each edge is the set {1, 2, ..., n-1}.

A Note on Set Graceful Labeling of Graphs
, 2011 We settle affirmatively a conjecture posed in [S. M. Hegde, Set colorings of graphs, European Journal of Combinatorics 30 (4) (2009), 986--995]: If some subsets of a set X are assigned injectively to all vertices of a complete bipartite graph G such that the collection of all sets, each of which is the symmetric difference of the sets assigned to the ...

Effects of Galactic Irradiation on Thermal and Electronic Transport in Tungsten
physica status solidi (b), EarlyView.This atomic‐scale study reveals how low‐to‐mid‐energy space irradiation alters tungsten's thermal and electronic behavior, even at low defect levels. Focusing on vacancy sites in bulk and near grain boundaries, it employs two novel approaches: site‐projected thermal conductivity and the N2$^{2}$ method for the thermal and electronic response analysis ...

Graceful labelings of the generalized Petersen graphs
Communications in Combinatorics and Optimization, 2017 A graceful labeling of a graph $G=(V,E)$ with $m$ edges is an injection $f: V(G) \rightarrow \{0,1,\ldots,m\}$ such that the resulting edge labels obtained by $|f(u)-f(v)|$ on every edge $uv$ are pairwise distinct.

Robust Photonic Quantum Gates With A Large Number of Waveguide Segments
Advanced Quantum Technologies, EarlyView.This study investigates segmented waveguide designs for photonic quantum gates, extending existing composite approaches to a large number of segments. Through numerical simulations, the work analyzes fidelity, power loss, and the effect of noise correlations.
