The Bird Core for Minimum Cost Spanning Tree problems Revisited: Monotonicity and Additivity Aspects [PDF]
A new way is presented to define for minimum cost spanning tree (mcst-) games the irreducible core, which is introduced by Bird in 1976.The Bird core correspondence turns out to have interesting monotonicity and additivity properties and each stable cost

Electrically Induced Phase Transition and Synaptic Functionality in MoTe2/Graphene Memristors
Advanced Functional Materials, EarlyView.An electrically induced reversible 2H ↔ 1T′ phase transition is demonstrated in a vertical Au/Ti/MoTe2/graphene memristor with a laterally contacted graphene electrode. Resistive switching proceeds through a compositionally invariant amorphous/2H ↔ amorphous/1T′ transformation, in which a self‐formed amorphous MoTe2 interfacial region is proposed to ...

A fair rule in minimum cost spanning tree problems [PDF]
We study minimum cost spanning tree problems and define a cost sharing rule that satisfies many more properties than other rules in the literature.

Advanced Functional Materials, EarlyView.Rapid microwave plasma torch engineering tunes crystal phases, carbon graphitization and oxygen‐vacancy defects in HfO2/C@C core‐shell fibrous membranes. Synergistic multi‐loss effects optimize impedance matching to deliver −65.75 dB reflection loss and a 7.37 GHz effective bandwidth for flexible electromagnetic wave absorption.

Monotonic nature of the Gamma function
Journal of Inequalities and ApplicationsThis study begins by examining the monotonic behavior of the function ln Γ ( x + 1 ) / ( ln ( x 2 + 6 ) − ln ( x + 6 ) ) $\ln \Gamma (x+1)/\left (\ln \left (x^{2}+6\right )-\ln (x+6)\right )$ on the interval x ∈ ( − 1 , 1 ) $x\in (-1,1)$ , supported by ...

An Adaptive Inhibitory WSe2 Transistor for Retinomorphic In‐Sensor Image Processing
Advanced Functional Materials, EarlyView.Conventional retinomorphic devices typically require deliberate gate‐bias tuning for each illumination condition. In this paper, we demonstrate an adaptive inhibitory WSe2 transistor that uses photo‐induced regime shift between the subthreshold and accumulation modes to achieve decision‐free, intensity‐adaptive image processing within a single pixel ...

Wilker–Huygens type inequalities for p-generalized lemniscate and hyperbolic lemniscate functions
Demonstratio MathematicaThis paper extends Wilker–Huygens inequalities to p-generalized (arc) lemniscate functions. First, we define p-generalized lemniscate functions and their hyperbolic analogues based on the (p, 2p)-generalized trigonometric and hyperbolic functions.

Testing strict monotonicity in nonparametric regression [PDF]
A new test for strict monotonicity of the regression function is proposed which is based on a composition of an estimate of the inverse of the regression function with a common regression estimate. This composition is equal to the identity if and only if

Advanced Functional Materials, EarlyView.Mask‐encoded UV exposure translates digital color information into pixel‐resolved structural‐color patterns in hydroxypropyl cellulose gels. Gaussian‐process‐guided calibration links UV processing conditions, wavelength, and mask opacity, enabling parallel fabrication of multicolor images in a single 10 s exposure.

Divergence and Sufficiency for Convex Optimization
Entropy, 2017 Logarithmic score and information divergence appear in information theory, statistics, statistical mechanics, and portfolio theory. We demonstrate that all these topics involve some kind of optimization that leads directly to regret functions and such ...
