Degeneracy Sensing Light Detection and Ranging‐Inertial Simultaneous Localization and Mapping with Dual‐Layer Resistant Odometry and Scan‐Context Loop‐Closure Detection Backend in Diverse Environments

Advanced Intelligent Systems, EarlyView.
This paper presents a degeneracy‐aware light detection and ranging (LiDAR)‐inertial framework that enhances LiDAR simultaneous localization and mapping performance in challenging environments. The proposed system integrates a dual‐layer robust odometry frontend with a Scan‐Context‐based loop‐closure detection backend.

Rayleigh-Ritz variation method and connected-moments polynomial approach

, 2008
We show that the connected-moments polynomial approach proposed recently is equivalent to the well known Rayleigh-Ritz variation method in the Krylov space.

The impact of urbanisation on social behaviour: a comprehensive review

Biological Reviews, EarlyView.
ABSTRACT Urbanisation is a key driver of global environmental change and presents animals with novel stressors and challenges. It can fundamentally influence social behaviour and has the potential to reshape within‐ and between‐species social interactions. Given the role of social behaviour in reproductive fitness and survival, understanding how social

Innovative Application of the Ritz Method to Oil-Gas Seepage Problems: A Novel Variational Approach for Solving Underground Flow Equations

Energies
State-of-the-art commercial simulators (e.g., Eclipse, CMG) predominantly employ finite difference schemes, which face persistent challenges in modeling strongly nonlinear seepage dynamics. This study explores the application of the Ritz method, grounded

Determination of Resonances by the Optimized Spectral Approach

, 2012
The Rayleigh-Ritz procedure for determining bound-states of the Schr\"{o}dinger equation relies on spectral representation of the solution as a linear combination of the basis functions.

Managers' Sustainability Mindset: The Role of Place Attachment and Absorptive Capacity

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Sustainability mindset among managers is crucial for advancing sustainable development and creating long‐term environmental and social value. This study focuses on middle managers in Indian organizations and explores how place attachment and managerial absorptive capacity affect their sustainability mindset.

Acute and Chronic Toxicity of Sediments Containing Platinum and Palladium on Freshwater Benthic Organisms Chironomus riparius and Hyalella azteca

Journal of Applied Toxicology, EarlyView.
ABSTRACT The expanding demand for platinum group elements (PGEs) in industrial and medical applications has led to their increasing accumulation in aquatic sediments. However, their ecological impacts remain poorly understood, particularly for sediment‐dwelling invertebrates. This study assessed the toxicity of platinum (Pt) and palladium (Pd) across a

Analytic Variational Investigation of Euclidean SU(3) Gauge Theory

, 1993
Analytic variational techniques for lattice gauge theories based on the Rayleigh-Ritz(RR) method were previously developed for euclidean SU(2) gauge theories in 3 and 4 dimensions.

Grandmother's pregnancy complications and autism spectrum disorders in grandchildren, a California multigenerational cohort study

JCPP Advances, EarlyView.
Abstract Background Pregnancy complications have been associated with offspring autism spectrum disorders (ASD). There has also been increasing evidence for multigenerational risk factors of ASD. Methods In a multigenerational California birth cohort of 1,740,379 mother–child pairs, we investigated pregnancy complications when the grandmother was ...
