Algebraic methods for reconstruction of coordinates in strip detectors [PDF]
JINST 18 C06001 (2023), 2023 Many types of detectors, such as cathode strip chambers and some MPGDs, allow us to reconstruct track positions by induced strip charges. There are two main types of algebraic methods for this reconstruction: center of gravity methods and little-known differential methods. General formulas for differential methods are derived.

On the method of reflections [PDF]
Numerische Mathematik, 2021 This paper aims at reviewing and analysing the method of reflections. The latter is an iterative procedure designed to linear boundary value problems set in multiply connected domains. Being based on a decomposition of the domain boundary, this method is particularly well-suited to numerical solvers relying on integral representation formulas.

Parameter Estimation of KST-IRT Model under Local Dependence
Psych, 2023 A mantra often repeated in the introductory material to psychometrics and Item Response Theory (IRT) is that a Rasch model is a probabilistic version of a Guttman scale. The idea comes from the observation that a sigmoidal item response function provides
