Advanced Engineering Materials, EarlyView.HEA interlayers offer a versatile route for joining high‐performance structural materials. Their compositional and structural design regulates interfacial reactions, suppresses brittle IMCs, and improves metallurgical bonding. Sandwich interlayers further integrate defect healing with precipitation strengthening, enabling improved strength–ductility ...

Bootstrapping extremal scalar amplitudes with and without supersymmetry
Journal of High Energy PhysicsWe re-examine positivity bounds on the 2 → 2 scattering of identical massless real scalars with a novel perspective on how these bounds can be used to constrain the spectrum of UV theories.

An extremal problem for univalent functions [PDF]
Let S be the class of functions f(z)=z+a2z2 ,… f(0)=0, f′(0)=1 which are regular and univalent in the unit disk |z| x the equation φ′( x)=0 does not have real roots. Since S is a compact class, there exists x . This problem was first proposed by Petru T.

Stretching the Printability Metric in Direct‐Ink Writing with Highly Extensible Yield‐Stress Fluids
Advanced Functional Materials, EarlyView.This study introduces “drawability” as a new metric for assessing printability in direct‐ink writing, focusing on gap‐spanning performance and speed robustness. By designing yield‐stress fluids with high extensibility, we demonstrate that extensional strain‐to‐break significantly enhances printability.

The Extremal Permanental Sum for a Quasi-Tree Graph
Complexity, 2019 Let G be a graph and A(G) the adjacency matrix of G. The permanent of matrix (xI-A(G)) is called the permanental polynomial of G. The permanental sum of G is the sum of the absolute values of the coefficients of permanental polynomial of G. Computing the

Solving M-theory with the conformal bootstrap
Journal of High Energy Physics, 2018 We use the conformal bootstrap to perform a precision study of 3d maximally supersymmetric ( N=8 $$ \mathcal{N}=8 $$) SCFTs that describe the IR physics on N coincident M2-branes placed either in flat space or at a ℂ4 /ℤ2 singularity.

On the universal method to solve extremal problems [PDF]
Some applications of the theory of extremal problems to mathematics and economics are made more accessible to non-experts.1.The following fundamental results are known to all users of mathematical techniques, such as economist, econometricians, engineers

Advanced Functional Materials, EarlyView.In MOCVD MoS2 memristors, a current compliance‐regulated Ag filament mechanism is revealed. The filament ruptures spontaneously during volatile switching, while subsequent growth proceeds vertically through the MoS2 layers and then laterally along the van der Waals gaps during nonvolatile switching.

Gaussian Tests of "Extremal White Noise" for Dependent, Heterogeneous, Heavy Tailed Strochastic Processes with an Application [PDF]
We develop a non-parametric test of tail-specific extremal serial dependence for possibly heavy-tailed time series. The test statistic is asymptotically chi-squared under a null of "extremal white noise", as long as extremes of the time series are Near ...
