Decomposition of skill scores for conditional verification: impact of Atlantic Multidecadal Oscillation phases on the predictability of decadal temperature forecasts [PDF]

Geoscientific Model Development
As the performance of weather and climate forecasting systems and their benchmark systems are generally not homogeneous in time and space and may vary in specific situations, improvements in certain situations or subsets have different effects on overall

Sono‐Mechanogenetics: Linking Ultrasound Physics With Cellular Mechanobiology

Advanced Science, EarlyView.
Sono‐mechanogenetics links ultrasound physics with cellular mechanotransduction to enable noninvasive control of engineered biological systems. Acoustic forces generate distinct deformation modes that activate intracellular signaling pathways, which can be coupled to synthetic gene circuits to regulate diverse cellular functions, including gene ...

Phase‐Resolved Defect Transport Mechanisms Governing Asynchronous Ordering in a Eutectic High‐Entropy Alloy

Advanced Science, EarlyView.
Phase‐resolved experiments and atomistic simulations reveal asynchronous ordering behaviors in a eutectic high‐entropy alloy during isothermal annealing. Distinct defect transport mechanisms are identified in coexisting B2 and BCC phases, showing that vacancy and interstitial mediated diffusion governs phase‐dependent thermal stability.

Constants in the oscillation theory of higher order Sturm-Liouville differential equations

Electronic Journal of Differential Equations, 2002
We find the the exact value of a constant in some oscillation criteria for the higher order Sturm-Liouville differential equation $$ (-1)^{n}(t^alpha y^{(n)})^{(n)}=q(t)y . $$ We also study some general aspects in the oscillation theory of this equation.

Conditions for Oscillation of a Neutral Differential Equation [PDF]

International Journal of Differential Equations, 2010
For a neutral differential equation with positive and changeable sign coefficients [x(t)−a(t)x(δ(t))]′ + p(t)F(x(τ(t))) − q(t)G(x(σ(t))) = 0, oscillation criteria are established, where q(t) is not required as nonnegative. Several new results are obtained.
