Forbidden Triples Generating a Finite set of 3-Connected Graphs [PDF]
The Electronic Journal of Combinatorics, 2015 For a graph $G$ and a set $\mathcal{F}$ of connected graphs, $G$ is said be $\mathcal{F}$-free if $G$ does not contain any member of $\mathcal{F}$ as an induced subgraph. We let $\mathcal{G} _{3}(\mathcal{F})$ denote the set of all $3$-connected $\mathcal{F}$-free graphs.

Laser‐Induced Graphene from Waste Almond Shells
Advanced Functional Materials, EarlyView.Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

Minimal forbidden sets for degree sequence characterizations
Discrete Mathematics, 2015 Given a set $\mathcal{F}$ of graphs, a graph $G$ is $\mathcal{F}$-free if $G$ does not contain any member of $\mathcal{F}$ as an induced subgraph. Barrus, Kumbhat, and Hartke [M. D. Barrus, M. Kumbhat, and S. G. Hartke, Graph classes characterized both by forbidden subgraphs and degree sequences, J. Graph Theory (2008), no.

Designing transparent conductors using forbidden optical transitions [PDF]
, 2023 Many semiconductors present weak or forbidden transitions at their fundamental band gaps, inducing a widened region of transparency. This occurs in high-performing n-type transparent conductors (TCs) such as Sn-doped In 2 O 3 (ITO); however, thus far ...

Glissile Interphase Boundaries Enable Collective Phase Switching in Epitaxial Polar Oxides
Advanced Functional Materials, EarlyView.A triple point is identified in the phase diagram of low‐symmetry epitaxial BiFeO3 thin film along with an extended regime of phase competition associated with a flattened energy landscape. The electromechanical response is shown to be governed by correlated interphase‐boundary motion, including scale‐free avalanche dynamics characteristic of systems ...

Global Behavior of a Rational Difference Equation
四川大学学报. 自然科学版, 2018 In this paper, we determine the forbidden set, introduce an explicit formula for the solutions, and discuss the global behavior of a rational difference equation x_(n+1)=(x_n x_(n-k))/(αx_n+βx_(n-(k+1)) ), where inter k∈N, inter n∈N∪{0},α,β are real ...

IEEE Access, 2017 Deciding how to prevent discrete event systems (DESs) from reaching forbidden states is an important problem in the field of DES supervisory control. For DESs with uncontrollable events, linear constraint transformation becomes a popular technique for ...

Room‐Temperature Synthesis of Strongly Confined Lead Halide Perovskite Quantum Dots
Advanced Functional Materials, EarlyView.CsPbX3${\rm CsPbX}_3$ lead halide perovskite quantum dots (QDs) are synthesized in a room‐temperature, five‐minute synthesis, yielding size‐controlled QDs with bright, tunable emission governed by reaction conditions and halide composition. A strongly binding ligand, OD‐PEA, ensures months‐long stability under ambient conditions and facilitates their ...

Freeze-out forbidden dark matter in the hidden sector in the mass range from sub-GeV to TeV
Journal of High Energy Physics, 2022 Kinematically forbidden channels can set the freeze-out dark matter (DM) relic abundance. These channels are described by DM annihilations into heavier states, which vanish at zero temperature limit, but occur at finite temperatures in the early Universe.
