Assessing the role of spatial externalities in the survival of Italian innovative startups

Regional Science Policy &Practice, EarlyView., 2023
Abstract The paper provides novel empirical evidence about the effects of spatial externalities on the survival of innovative startups in Italy. Using geocoded firm‐level data, we build micro‐geographic measures of specialization and diversity that are robust to the modifiable areal unit problem.

Target strength error from the Kirchhoff-approximation and Kirchhoff-ray-mode models at two tilt angles.

, 2013
Difference in length-normalised target strength for the Kirchhoff-approximation (KA) and Kirchhoff-ray-mode (KRM) and models compared to the prolate-spheroid-modal-series model as a function of ka and kb at a tilt angle of 0° (panel A: KA, panel C: KRM ...

STOCHASTIC MODEL OF MICROPARTICLE SCATTERING ON A CRYS-TAL

Avances en Ciencias e Ingeniería, 2021
This paper shows that the stochastic approach to solving the problem of the scattering of elementary particles on crystal can serve as an alternative to Louis de Broglie's hypothesis on the wave properties of material particles.

Physics‐Informed Neural Network‐Enabled Forward Prediction and Inverse Design of Ring Origami

Advanced Science, EarlyView.
This work presents a KRT‐PINN framework that integrates Kirchhoff rod theory with physics‐informed neural networks for the forward prediction and inverse design of ring origami consisting of closed‐loop rods. The framework predicts stable states of segmented rings with prescribed natural‐curvature profiles and determines the natural‐curvature profiles ...

Integration of Reconfigurable p‐Bit and 1R Crossbar Array for Memristive Probabilistic Computing

Advanced Science, EarlyView.
A memristive probabilistic computing system is demonstrated by integrating stochastic p‐bits based on volatile memristors with a 1R crossbar array encoding interaction weights. The system performs weighted‐sum operations across the array and updates p‐bits iteratively.

Existence of solution for Kirchhoff model problems with singular nonlinearity

Electronic Journal of Qualitative Theory of Differential Equations, 2021
We study the fourth order Kirchhoff equation $\Delta^2 u - (a+b \int_{\Omega} |\nabla u|^2)^\gamma \Delta u = f(u)$ in $\Omega$ with $-\Delta u > 0$ and $u > 0$ in $\Omega$, and $\Delta u = u = 0$ on $\partial \Omega$, where $f(t) = \alpha \frac{1}{t ...
