Solving Standard and Generalized EMPM Eigenvalue Problems: A QUBO Approach for the D-Wave Quantum Annealer [PDF]

EPJ Web of Conferences
Within the Equation of Motion Phonon Method (EMPM) framework, we address the computation of the ground-state eigenpair of nuclear Hamiltonians by reformulating the eigenvalue problem as a Quadratic Unconstrained Binary Optimization (QUBO).

Nonlinear stepsize control, trust regions and regularizations for unconstrained optimization [PDF]

, 2013
A class of algorithms for unconstrained optimization is introduced, which subsumes the classical trust-region algorithm and two of its newer variants, as well as the cubic and quadratic regularization methods.

Beyond Dexterity: Navigating the Trade‐Offs of Steerable Catheter‐ and Guidewire‐Based Endovascular Robotics for Clinical Applications

SmartBot, EarlyView.
Steerable catheters and guidewires enable precise navigation and intervention in complex vascular anatomies. This review systematically examines their steering mechanisms, including morphological, transmission‐based, and transduction‐based actuation, highlighting their underlying principles and engineering characteristics.

Local quadratic convergence of polynomial-time interior-point methods for conic optimization problems [PDF]

In this paper, we establish a local quadratic convergence of polynomial-time interior-point methods for general conic optimization problems. The main structural property used in our analysis is the logarithmic homogeneity of self-concordant barrier ...

High‐Throughput FRET Affinity Screening Technique (HTFAST) for Cell‐Free Expressed Binding Protein Characterization

Small, EarlyView.
High‐Throughput FRET Affinity Screening Technique (HTFAST) for quantitative, purification‐free affinity screening of cell‐free expressed binders. A fluorescent‐protein‐fused binder (donor) is expressed directly in crude E. coli cell‐free lysate and titrated against a dye‐labeled antigen (acceptor).

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 ...

Parallelizable search-space decomposition for large-scale combinatorial optimization problems using quadratic unconstrained binary optimization

Scientific Reports
Combinatorial optimization problems are crucial in industry. However, many COPs are NP-hard, causing the search space to grow exponentially with problem size and rendering large-scale instances computationally intractable.

Differential item functioning detection across multiple groups

British Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract Differential item functioning (DIF) can be investigated by estimating item response theory (IRT) parameters separately for different respondent groups, thus allowing for the detection of discrepancies in parameter estimates across groups. However, before comparing the estimates, it is necessary to convert them to a common metric due to the ...

Computing Skinning Weights via Convex Duality

Computer Graphics Forum, EarlyView.
We present an alternate optimization method to compute bounded biharmonic skinning weights. Our method relies on a dual formulation, which can be optimized with a nonnegative linear least squares setup. Abstract We study the problem of optimising for skinning weights through the lens of convex duality.
