Free-Space Characterization Setup for Low-Loss UV-261nm Waveguides in Aluminum Oxide
Here, we report a characterization setup for low-loss integrated photonic waveguides in aluminum oxide, tailored for deep UV applications. The setup includes a 261nm UV light source, objective lenses for free-space coupling, an automated stage, and a UV camera. The measured losses for the aluminum oxide waveguides in the UV-261nm range were calculated to be 4.9485 dB/cm. These results demonstrate the effectiveness of the setup in achieving low-loss characterization of integrated photonics waveg…

$20'$ Five-Point Function of $\mathcal{N}=4$ SYM and Stringy Corrections
We setup a bootstrap approach to compute the first stringy correction to the supergravity regime of the correlation function of five $20'$ operators in $\mathcal{N}=4$ super Yang-Mills. We use factorization of Mellin amplitudes and supersymmetric constraints to fix almost completely our ansatz. The two last coefficients are fixed by a justified mild assumption based on the flat-space limit of the Mellin amplitude. As a byproduct of our analysis, we also compute the first stringy correction to t…

Experimental Verification of a Time-Domain Load Identification Method for Single-Phase Circuits
This paper presents experimental validation of a time-domain load parameter determination method for single-phase circuits. The verification is performed in a state-of-the-art smart grid laboratory equipped with power hardware and real-time emulators. The proposed method enables the identification of circuit parameters using only instantaneous voltage and current measurements at the point of common coupling. The experimental setup includes a range of test cases covering linear and non-sinusoida…

Efficient Qudit Circuit for Quench Dynamics of $2+1$D Quantum Link Electrodynamics
A major challenge in the burgeoning field of quantum simulation for high-energy physics is the realization of scalable $2+1$D lattice gauge theories on state-of-the-art quantum hardware, which is an essential step towards the overarching goal of probing $3+1$D quantum chromodynamics on a quantum computer. Despite great progress, current experimental implementations of $2+1$D lattice gauge theories are mostly restricted to relatively small system sizes and two-level representations of the gauge …

A Robust Nonparametric Framework for Detecting Repeated Spatial Patterns
Identifying spatially contiguous clusters and repeated spatial patterns (RSP) characterized by similar underlying distributions that are spatially apart is a key challenge in modern spatial statistics. Existing constrained clustering methods enforce spatial contiguity but are limited in their ability to identify RSP. We propose a novel nonparametric framework that addresses this limitation by combining constrained clustering with a post-clustering reassigment step based on the maximum mean disc…

Force-Based Viscosity and Elasticity Measurements for Material Biomechanical Characterisation with a Collaborative Robotic Arm
Diagnostic activities, such as ultrasound scans and palpation, are relatively low-cost. They play a crucial role in the early detection of health problems and in assessing their progression. However, they are also error-prone activities, which require highly skilled medical staff. The use of robotic solutions can be key to decreasing the inherent subjectivity of the results and reducing the waiting list. For a robot to perform palpation or ultrasound scans, it must effectively manage physical i…

A highly-compact and ultra-fast homogeneous electromagnetic calorimeter based on oriented lead tungstate crystals
Progress in high-energy physics has been closely tied to the development of highperformance electromagnetic calorimeters. Recent experiments have demonstrated the possibility to significantly accelerate the development of electromagnetic showers inside scintillating crystals typically used in homogeneous calorimeters based on scintillating crystals when the incident beam is aligned with a crystallographic axis to within a few mrad. In particular, a reduction of the radiation length has been mea…

Néel vector controlled exceptional contours in $p$-wave magnet-ferromagnet junctions
Non-Hermitian systems can host exceptional degeneracies where not only the eigenvalues, but also the corresponding eigenvectors coalesce. Recently, $p$-wave magnets have been introduced, which are characterized by their unusual odd parity. In this work, we propose the emergence of non-Hermitian degeneracies at the interface of $p$-wave magnets and ferromagnets. We demonstrate that this setup offers a remarkable tunability allowing realization of exceptional lines and rings, which can be control…

Experimental demonstration of high-fidelity logical magic states from code switching
Preparation of high-fidelity logical magic states has remained as a necessary but daunting step towards building a large-scale fault-tolerant quantum computer. One approach is to fault-tolerantly prepare a magic state in one code and then switch to another, a method known as code switching. We experimentally demonstrate this protocol on an ion-trap quantum processor, yielding a logical magic state encoded in an error-correcting code with state-of-the-art logical fidelity. Our experiment is base…

EPC Framework for BESS Projects
Battery Energy Storage Systems (BESS) are critical for modern power networks, supporting grid services such as frequency regulation, peak shaving, and black start. Delivering a BESS under an Engineering, Procurement, and Construction (EPC) model requires a concise methodology that balances regulatory compliance, technical details, and schedule efficiency. This paper presents a streamlined, five step EPC framework covering feasibility assessment, permitting, procurement, construction, and commis…
