Compile‐Once Block Encodings for Masked Similarity‐Transformed Effective Hamiltonians

Advanced Quantum Technologies, Volume 9, Issue 9, September 2026.
Composer transforms structured electronic‐structure operators into a reusable quantum‐circuit fabric. Once compiled, the same block‐encoding architecture is re‐dialed through coefficients, rotation angles, and masks to generate similarity‐transformed effective Hamiltonians across related problem instances, avoiding repeated structural recompilation ...

Local Asymmetric Least Squares (LAsLS) for Noisy and Complex Baseline Correction

Journal of Chemometrics, Volume 40, Issue 8, August 2026.
ABSTRACT The asymmetric least squares (AsLS) method is commonly used and works well when baseline characteristics are relatively uniform, but can be less accurate for non‐uniform, complex, or noisy baselines. Here, we present local AsLS (LAsLS), a local extension of AsLS that preserves the original penalized least‐squares framework while allowing ...

An Algebraic Solution for the Candecomp/PARAFAC Decomposition with Circulant Factors [PDF]

SIAM Journal on Matrix Analysis and Applications, 2014
The Candecomp/PARAFAC decomposition (CPD) is an important mathematical tool used in several fields of application. Yet, its computation is usually performed with iterative methods which are subject to reaching local minima and to exhibiting slow convergence.

Angle-Polarization Estimation for Coherent Sources with Linear Tripole Sensor Arrays

Sensors, 2016
We propose a parallel factor (PARAFAC) analysis-based angle and polarization estimation algorithm for multiple coherent sources using a uniformly-spaced linear tripole sensor array.

Efficient Tensor Completion Algorithms for Highly Oscillatory Operators

Numerical Linear Algebra with Applications, Volume 33, Issue 4, August 2026.
ABSTRACT We address the problem of recovering highly oscillatory operators, represented as n×n$$ n\times n $$ matrices with a fixed set of observed entries. Given that these matrices can be well compressed by butterfly matrix decomposition of L=𝒪(logn) levels requiring only O(nlogn)$$ O\left(n\log n\right) $$ degrees of freedom, we propose a novel ...

Tensor Decomposition for Fast Parsing with Latent-Variable PCFGs [PDF]

, 2012
We describe an approach to speed-up inference with latent-variable PCFGs, whichhave been shown to be highly effective for natural language parsing. Our approachis based on a tensor formulation recently introduced for spectral estimation oflatent-variable

Cramer-Rao Bound and Fitting Algorithm for PARAFAC Decomposition Under Constant-Modulus Constraints

工程科学与技术, 2009
:To analyze the parameter estimation performance of PARAFAC decomposition under Constant Modulus (CM) constraint, Cramer Rao Bound (CRB) expressions for PARAFAC decomposition under “First Row Known” and CM constraints were proposed.

Multidimensional Insights Into the Drivers of Aquatic CO2 Dynamics: A River–Reservoir–Wetland Aquatic Continuum Study Within a Semi‐Arid Region

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Evaluating multiple competing biotic and abiotic processes and how they interact with carbon dioxide (CO2) in aquatic systems, is critical to understanding regional and global carbon cycles. Here, we used an aquatic continuum of the Bahe watershed, within a semi‐arid region, to establish a comprehensive conceptual framework for identifying CO2
