Matrix Multiplication Using Only Addition [PDF]

, 2023
Matrix multiplication consumes a large fraction of the time taken in many machine-learning algorithms. Thus, accelerator chips that perform matrix multiplication faster than conventional processors or even GPU's are of increasing interest. In this paper,

DigiChrom: A Domain Ontology for Semantic Representation of Trivalent Chromium Platings and Its Large Language Model‐Based Alignment With Multiple Mid‐Level Ontologies

Advanced Engineering Materials, EarlyView.
Digitalizing electroplating requires both domain knowledge and interoperability. This work introduces PlatOn, a domain ontology for trivalent chromium plating and coating characterization, and a hybrid pipeline that aligns it to a mid‐level reference ontology by combining eight similarity metrics with language model reasoning. Expert‐validated mappings

Chain-Linked Multiple Matrix Integration via Embedding Alignment

Journal of the American Statistical Association
Motivated by the increasing demand for multi-source data integration in various scientific fields, in this paper we study matrix completion in scenarios where the data exhibits certain block-wise missing structures -- specifically, where only a few noisy submatrices representing (overlapping) parts of the full matrix are available. We propose the Chain-

Stable solutions of linear systems involving long chain of matrix multiplications

Linear Algebra and its Applications, 2011
The authors propose two numerical methods for solving linear system \((I_n + B_L \dots B_2 B_1)x=b\) arising from the Green's function calculation in the quantum Monte Carlo simulation of interacting electrons. The methods are based on the QR decomposition with column pivoting and the singular value decomposition, respectively, and provide a weakly ...

Gallium Microalloying in Bi–Sn Solders: Interfacial Phase Formation, Wettability, and Long‐Term Shear Reliability Under Isothermal Aging

Advanced Engineering Materials, EarlyView.
Gallium microalloying redirects interfacial reactions in low‐temperature Bi–Sn solders from Cu–Sn toward Cu–Ga intermetallic formation. The resulting Cu–Ga layer suppresses intermetallic growth during thermal aging, alters fracture pathways, and improves interfacial stability.

Evaluation of a computer-model for PVDF-transducers of arbitrary configuration

Archives of Acoustics, 2015
The electro-mechanical behaviour of PVDF can be described by the modified Mason equivalent circuit. It is possible to extract all necessary parameters and their frequency dependence from electrical input-impedance measurements and subsequent fitting ...

Counterion Dependent Side‐Chain Relaxation Stiffens a Chemically Doped Thienothiophene Copolymer

Advanced Functional Materials, EarlyView.
Oxidation of a thienothiophene copolymer, p(g3TT‐T2), via different doping strategies and dopant molecules resulted in materials with similar oxidation levels and a high electrical conductivity of ≈100 S cm−1. However, mechanical properties varied significantly, with sub‐glass transition temperatures and elastic moduli spanning from –44°C to –3°C and ...
