Considering spatiotemporal evolutionary information in dynamic multi‐objective optimisation

CAAI Transactions on Intelligence Technology, EarlyView., 2023
Abstract Preserving population diversity and providing knowledge, which are two core tasks in the dynamic multi‐objective optimisation (DMO), are challenging since the sampling space is time‐ and space‐varying. Therefore, the spatiotemporal property of evolutionary information needs to be considered in the DMO.

SSA of biomedical signals: A linear invariant systems approach [PDF]

, 2010
Singular spectrum analysis (SSA) is considered from a linear invariant systems perspective. In this terminology, the extracted components are considered as outputs of a linear invariant system which corresponds to finite impulse response (FIR) filters ...

Principal Component‐Based Classification of Blazar Candidates of Uncertain Type in the 4FGL/LAT

Astronomische Nachrichten, EarlyView.
ABSTRACT We adopted principal component analysis (PCA), linear discriminant analysis (LDA), and support vector machines (SVM), to study classification for a sample of 2708 Fermi blazars: 1142 BL Lac objects (BLLs), 759 flat spectrum radio quasars (FSRQs), and 807 blazar candidates of uncertain type (BCUs).

Forecasting VARMA processes using VAR models and subspace-based state space models [PDF]

VAR modelling is a frequent technique in econometrics for linear processes. VAR modelling offers some desirable features such as relatively simple procedures for model specification (order selection) and the possibility of obtaining quick non-iterative ...

From Data to Dimers: Engineering Acene Derivatives for Photovoltaic Singlet Fission

Chemistry – A European Journal, EarlyView.
Excited‐state energies of acene derivatives are predicted using a ChemBERTa‐based regression model and subsequently used to screen candidates for photovoltaic singlet fission using dimer–monomer benchmarked energetic criteria. Promising candidates are predominantly 5‐ and 6‐fused heteroacenes, which offer enhanced stability and higher triplet energies ...

TAMNet: Temporal and adaptive‐frequency network with MixStyle for cross‐region oil and fluid production forecasting

Deep Underground Science and Engineering, EarlyView.
This paper presents temporal and adaptive‐frequency network with MixStyle (TAMNet), a deep time‐series modeling framework for accurate and robust multi‐well oil productivity forecasting. TAMNet integrates transformer and long short‐term memory architectures to capture both short‐ and long‐term temporal dependencies, enhanced by a temporal gate unit ...

Subspaces spanned by eigenforms with nonvanishing twisted central L -values

Canadian Journal of Mathematics
Abstract In this article, we construct explicit spanning sets for two spaces of modular forms. One is the subspace generated by integral-weight Hecke eigenforms with nonvanishing quadratic twisted central L -values.

Seismic Performance of Reduced‐Strength Steel MRFs With SMA‐Based Superelastic Friction Dampers: An Experimental Investigation

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Shape memory alloys (SMAs) exhibit excellent self‐centering capability due to their stress‐induced phase transformation, making them highly suitable for applications in resilient infrastructure. This study investigates the seismic performance of reduced‐strength moment‐resisting frames (MRFs) equipped with SMA‐based superelastic friction ...

Enhancing the Seismic Resilience of Masonry‐Infilled RC Structures Using Rubber Joints: Full‐Scale 3D Shaking Table Tests

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Masonry infills in reinforced concrete (RC) frames are highly vulnerable to seismic damage, often sustaining severe cracking even under moderate ground motion, which in turn leads to considerable economic losses and safety risks. To address this issue, this study experimentally evaluates the effectiveness of two innovative rubber‐based joints ...
