Spectral Matching through Data Compression [PDF]

open access: yes, 2011
This paper proposes to use compression-based similarity measures to cluster spectral signatures on the basis of their similarities. Such universal distances estimate the shared information between two objects by comparing their compression factors ...

Functionalizing Micro‐to‐Mesoscopic Electrode Architectures for Regulating Electron Transfer Behaviors in Electrocatalysis

open access: yesAdvanced Functional Materials, EarlyView.
A systematic review is conducted to assess the influence of electrode architecture across micro‐ to mesoscopic length scales on electron‐transfer pathways in electrocatalysis. We discuss the structure‐activity relationships in electrocatalytic applications, including resource recovery and environmental remediation, and provide cost‐effective, efficient

Sulfur‐Free Ultrahigh‐Refractive‐Index Polymers Enabled by Densely Packed Oxygen‐Bridged Dibenzofuran‐Cardo Architectures

open access: yesAdvanced Functional Materials, EarlyView.
A new class of sulfur‐free, oxygen‐bridged dibenzofuran‐based polymers is developed for ultrahigh‐refractive‐index applications. The rigid π‐extended architecture and enhanced molecular polarizability enable exceptional optical performance, combining refractive indices up to 1.848 with high Abbe numbers and full visible transparency. This work offers a

Coordinated Architectural and Chemical Reinforcement in the Crushing Mandible of a Soldier Termite

open access: yesAdvanced Functional Materials, EarlyView.
The crushing mandible of a soldier termite withstands substantial biting loads despite lacking mineral. Its cuticle is partitioned: convex teeth pair hardness and zinc enrichment with aligned chitin fibers for contact durability, while stiffer concave regions between teeth carry bending loads.

The distance Seidel matrix of connected graphs

open access: yesAKCE International Journal of Graphs and Combinatorics
For a connected graph G, we present the concept of a new graph matrix related to its distance and Seidel matrix, called distance Seidel matrix [Formula: see text]. Suppose that the eigenvalues of [Formula: see text] be [Formula: see text] In this article,

Roll‐to‐Roll Processable EC/TC Hybrid Smart Windows Driven by a Bidirectional Dual‐Chromic Polymer Electrolyte

open access: yesAdvanced Functional Materials, EarlyView.
We present a scalable EC/TC hybrid smart window using a DCPE that enables tunable solar modulation (ΔTsol:15–43%), fast electrochromic switching (<90 s), and strong thermal blocking (10–14°C reduction). HPMC improves thermal stability, while an optimized ISL enhances EC performance.

The distance spectral radius of graphs with given number of odd vertices [PDF]

open access: yes, 2016
The graphs with smallest, respectively largest, distance spectral radius among the connected graphs, respectively trees with a given number of odd vertices, are determined. Also, the graphs with the largest distance spectral radius among the trees with a

3D Bioprinted Glioblastoma Multiforme Models: How the Extracellular Matrix Glycosignature Influences Drug Response

open access: yesAdvanced Functional Materials, EarlyView.
Aberrant glycosylation in the glioblastoma tumor microenvironment drives therapeutic resistance. Here, a 3D bioprinted model was engineered by incorporating α‐NeuNAc‐(2→3)‐β‐D‐Gal‐ and chondroitin sulfate. Combined multiplex immunofluorescence and synchrotron‐based nanoCT analysis revealed that glycan‐matrix interactions dictate specific drug‐escape ...

Connectivity, diameter, independence number and the distance spectral radius of graphs

open access: yes, 2017
© 2017 Elsevier Inc. The distance spectral radius of a graph is the largest eigenvalue of its distance matrix. X.L. Zhang (2012) [31] determined the n-vertex graphs of given diameter with the minimum distance spectral radius. In this paper, we generalize
