Quantum‐Native Formulations for X‐Ray Fluorescence: Spectral Overlap, Sparse Elemental Identification, and Spatial Inference

X-Ray Spectrometry, EarlyView.
ABSTRACT X‐ray fluorescence (XRF) analysis combines spectral inverse modeling, elemental support selection and spatial interpretation. We develop quadratic unconstrained binary optimization (QUBO) and Ising formulations for these tasks. A detector‐response dictionary of broadened candidate emission‐line profiles induces a spectral overlap graph that ...

PPEPV‐RDL: Achieving Privacy‐Preserving, Efficient, Publicly Verifiable Rational Delegation Learning

CAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Delegation learning is an implementation approach within privacy‐preserving machine learning (PPML). It refers to that the delegator outsources the training task to servers with strong computing power due to its own limited computing resources, and the servers return the correct training results and get the service revenue.

Mechanism of Quasi‐Power‐Frequency Resonant Overvoltage Triggered by Multiple Lightning Strikes in High‐Voltage Alternating Current Systems Equipped With Shunt Reactor

High Voltage, EarlyView.
ABSTRACT This paper investigates the generation mechanism of quasi‐power‐frequency resonant overvoltage triggered by multiple lightning strikes in high‐voltage alternating current (HVAC) systems equipped with shunt reactors. Based on field measurements from a 500 kV AC system, equivalent and simplified circuit models have been established to analyse ...

Conductivity Analysis and Thermoelectric Behaviour of Larch Standing Trees Under Lightning Currents: Role of Moisture Distribution and Carrier Motion

High Voltage, EarlyView.
ABSTRACT The direct effects of lightning strikes on forest combustibles form the foundation for predicting lightning‐induced forest fires. Accurate assessment of lightning impact is hindered by limited knowledge of the conduction characteristics of standing larch trees.

Polynomial‐shaped electrodes for adaptive X‐ray optics

Journal of Synchrotron Radiation, EarlyView.
A shaped electrode design for lithium niobate adaptive X‐ray mirrors connects actuator degrees of freedom to specific polynomial orders, enabling general shape control and the correction of defocus, coma and fourth‐order aberrations with a limited number of inputs.For adaptive mirrors on X‐ray beamlines and optical systems, we describe a strategy for ...
