Probing compressed higgsinos with forward protons at the LHC

open access: yesJournal of High Energy Physics, 2022
Supersymmetric models with nearly-degenerate light higgsinos provide a consistent solution to the naturalness problem under rigorous constraints from current experimental searches for sparticles.

Overset Grid Assembler and Flow Solver with Adaptive Spatial Load Balancing

open access: yesApplied Sciences, 2021
An overset mesh approach is useful for unsteady flow problems which involve components moving relative to each other. Since the generation of a single mesh around all components is prone to mesh stretching due to the relative motion of bodies, using the ...

Modeling Hypersonic Flow over a Spiked Blunt Body Using Adaptive Mesh Refinement on an Overset Grid [PDF]

open access: yesJournal of Applied Fluid Mechanics
In comparison to conventional single-grid methods, grid-adaptive overset techniques offer a strong, flexible, and efficient solution approach for computational fluid dynamics in the modeling of flows with complex interactions.

Parton distribution function for topological charge at one loop

open access: yesJournal of High Energy Physics, 2022
We present results for the gg-part of the one-loop corrections to the recently introduced “topological charge” GPD F ~ $$ \overset{\sim }{F} $$ (x, q 2). In particular, we give expression for its evolution kernel.

Observer‐Based Adaptive Event‐Triggered Tracking Control for Fuzzy TS Systems With Premise Mismatch

open access: yesInternational Journal of Adaptive Control and Signal Processing, EarlyView.
This paper presents an adaptive logistic event‐triggered observer‐based tracking controller for Takagi‐Sugeno fuzzy systems under constrained inputs and network delays. Leveraging a hybrid LMI and Secretary Bird Optimization approach, this strategy significantly minimizes communication overhead and computational burden while ensuring optimal reference ...

dynoGP: Deep Gaussian Processes for Dynamic System Identification

open access: yesInternational Journal of Adaptive Control and Signal Processing, EarlyView.
This work introduces a novel class of deep models for system identification, dynamical deep Gaussian processes, which combine the strengths of data‐driven methods, such as those based on neural network architectures, with the ability to output a probability distribution for uncertainty representation.

Amplitude analysis of B s 0  → K S 0 K ± π ∓ decays

open access: yesJournal of High Energy Physics, 2019
The first untagged decay-time-integrated amplitude analysis of B s 0  → K S 0 K ± π ∓ decays is performed using a sample corresponding to 3.0 fb−1 of pp collision data recorded with the LHCb detector during 2011 and 2012.

Mechanochemical Synthesis and Characterization of Nanostructured ErB4 and NdB4 Rare‐Earth Tetraborides

open access: yesAdvanced Engineering Materials, Volume 27, Issue 6, March 2025.
ErB4 and NdB4 nanostructured powders are produced by mechanochemical synthesis. 5 h mechanical alloying and 4 M HCl acid leaching are used in the production. ErB4 and NdB4 powders exhibit maximum magnetization of 0.4726 emu g−1 accompanied with an antiferromagnetic‐to‐paramagnetic phase transition at about TN = 18 K and 0.132 emu g−1 with a maximum at ...

Combined Process‐ and Phase‐Field‐Simulation to Predict the Microstructure of Single‐Crystal Ni‐Based Superalloys

open access: yesAdvanced Engineering Materials, EarlyView.
A combined finite element and phase‐field approach predicts the evolution of microstructure during the directional solidification of Ni‐based superalloys. The model reveals how withdrawal rate, temperature gradient, and wall thickness control the dendrite spacing, highlighting the strong effect of surface regions in thin sections where dendrite growth ...
