Universal Constraints on the Location of Extrema of Eigenfunctions of Non-Local Schr\"odinger Operators [PDF]

, 2019
We derive a lower bound on the location of global extrema of eigenfunctions for a large class of non-local Schr\"odinger operators in convex domains under Dirichlet exterior conditions, featuring the symbol of the kinetic term, the strength of the ...

(Nb,Ti)(C,N)‐Precipitates in High‐Strength Low‐Alloyed Steels—Modeling, Characterization and Validation

Advanced Engineering Materials, EarlyView.
Steel samples are investigated using complementary simulations and measurements. Transmission electron microscopy in bright‐field mode, combined with energy‐dispersive X‐ray spectroscopy maps for titanium and niobium, reveals distinct particle populations. Simulations reproduce these in size and composition.

Peptide Sequencing With Single Acid Resolution Using a Sub‐Nanometer Diameter Pore

Advanced Functional Materials, EarlyView.
To sequence a single molecule of Aβ1−42–sodium dodecyl sulfate (SDS), the aggregate is forced through a sub‐nanopore 0.4 nm in diameter spanning a 4.0 nm thick membrane. The figure is a visual molecular dynamics (VMD) snapshot depicting the translocation of Aβ1−42–SDS through the pore; only the peptide, the SDS, the Na+ (yellow/green) and Cl− (cyan ...

A Fractional Heston-Type Model as a Singular Stochastic Equation Driven by Fractional Brownian Motion

Fractal and Fractional
This paper introduces the fractional Heston-type (fHt) model as a stochastic system comprising the stock price process modeled by a geometric Brownian motion. In this model, the infinitesimal return volatility is characterized by the square of a singular

Interactions Between Active Matters and Endogenous Fields

Advanced Materials, EarlyView.
This review synthesizes endogenous field information and computational methods in contexts such as cancer, wounds, and biofilms. It organizes NAMs and AAMs by sensing, transmitting, and executing functions, compares their limitations, and from these contrasts proposes design strategies for next‐generation AAMs, offering perspectives to foster ...
