On factorization of generalized Macdonald polynomials [PDF]

open access: yes, 2016
A remarkable feature of Schur functions—the common eigenfunctions of cut-and-join operators from $$W_\infty $$—is that they factorize at the peculiar two-parametric topological locus in the space of time variables, which is known as the hook formula for ...

Smart and Sustainable Sizing: Investigating the Sensing Behavior of Glass Fabrics Coated With Waterborne Polyurethane/Graphene Dispersions

open access: yesAdvanced Materials Technologies, EarlyView.
Waterborne polyurethane/graphene formulations are developed as piezoresistive coatings on glass fabric to enable flexible strain sensing. The graphene‐enabled conductive network provides a stable electromechanical response under cyclic compression. The coating demonstrates reliable pressure‐dependent resistance changes, highlighting its potential for ...

Characterization of Droplet Formation in Ultrasonic Spray Coating: Influence of Ink Formulation Using Phase Doppler Anemometry and Machine Learning

open access: yesAdvanced Materials Technologies, EarlyView.
This study explores how machine learning models, trained on small experimental datasets obtained via Phase Doppler Anemometry (PDA), can accurately predict droplet size (D32) in ultrasonic spray coating (USSC). By capturing the influence of ink complexity (solvent, polymer, nanoparticles), power, and flow rate, the model enables precise droplet control

The Influence of Mesoscale Particle Structure on the Electrode Degradation and Resultant Electrochemistry of Lithium Ion Cells With Nickel Rich Lithium Nickel Manganese Cobalt Oxide Positive Electrodes

open access: yesAdvanced Materials Technologies, EarlyView.
Milled polycrystalline NMC811 cathode (MPC NMC) with smaller secondary particle and higher surface area had 1) greater cathode tortuosity, 2) reduced surface Ni on the cycled MPC cathodes consistent with surface reconstruction, and 3) increased Ni deposition from cathode‐anode crosstalk, manifesting in lower functional capacity and higher impedance ...

Factoring a Graph in Polynomial Time

open access: yesEuropean Journal of Combinatorics, 1987
The Cartesian product \(G\times H\) of graphs G and H has vertices (g,h) where g is a vertex in G and h a vertex in H. Two vertices of \(G\times H\), say \((g_ 1,h_ 1)\) and \((g_ 2,h_ 2)\), are connected by an edge in \(G\times H\), just when either \(\{g_ 1,g_ 2\}\) is an edge of G and \(h_ 1=h_ 2\), or when \(g_ 1=g_ 2\) and \(\{h_ 1,h_ 2\}\) is an ...
