Magnetic Field Variability as a Consistent Predictor of Solar Flares
Solar flares are intense bursts of electromagnetic radiation, which occur due to a rapid destabilization and reconnection of the magnetic field. While pre-flare signatures and trends have been investigated from magnetic observations prior to flares for decades, analysis which characterizes the variability of the magnetic field in the hours prior to flare onset has not been included in the literature. Here, the 3D magnetic field is modeled using a Non-Linear Force Free Field extrapolation for 6 …

Lasso Gripper: A String Shooting-Retracting Mechanism for Shape-Adaptive Grasping
Handling oversized, variable-shaped, or delicate objects in transportation, grasping tasks is extremely challenging, mainly due to the limitations of the gripper's shape and size. This paper proposes a novel gripper, Lasso Gripper. Inspired by traditional tools like the lasso and the uurga, Lasso Gripper captures objects by launching and retracting a string. Contrary to antipodal grippers, which concentrate force on a limited area, Lasso Gripper applies uniform pressure along the length of the …

Optimization-Based Image Restoration under Implementation Constraints in Optical Analog Circuits
Optical analog circuits have attracted attention as promising alternatives to traditional electronic circuits for signal processing tasks due to their potential for low-latency and low-power computations. However, implementing iterative algorithms on such circuits presents challenges, particularly due to the difficulty of performing division operations involving dynamically changing variables and the additive noise introduced by optical amplifiers. In this study, we investigate the feasibility …

Singular KAM theory for convex Hamiltonian systems
In this note, we briefly discuss how singular KAM Theory - which was worked out in a previous work by L.B. and L.C. for the mechanical case $\frac12 |y|^2+\varepsilon f(x)$ - can be extended to convex real analytic nearly integrable Hamiltonian systems with Hamiltonian in action-angle variables given by $h(y)+\varepsilon f(x)$ with $h$ convex and generic $f$.

Absence of $L^p$ spectrum for asymptotically flat diffusions in region with cavities
We study solutions to variable-coefficient elliptic equations of the form $-\D(A(x) \nabla u) = κu$, $κ>0$, in an exterior domain $\Om\subset \Rn$, where $A(x)$ is uniformly elliptic and asymptotically flat. Extending Rellich's classical $L^2$ result for the Laplacian, we show that if $u\in L^p(\Om)$ for some $0

FARS: Factor Augmented Regression Scenarios in R
Obtaining realistic scenarios for the distribution of key economic variables is crucial for econometricians, policy-makers, and financial analysts. The FARS package provides a comprehensive framework in R for modeling and designing economic scenarios based on distributions derived from multi-level dynamic factor models (ML-DFMs) and factor-augmented quantile regressions (FA-QRs). The package enables users to: (i) extract global and block-specific factors using a flexible multi-level factor stru…
