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.

Effect of process parameters on the surface forming accuracy of step of hollow step shaft formed by three-roll skew rolling

Metalurgija, 2021
This paper adopts a three-roll skew rolling technology with rolls that can either converge or move apart to form shafts with variable cross-section dimensions.

Gleaning the Rocky Shore? 2500 Years of Coastal Resource Use at Red Bluff 1, GunaiKurnai Country, SE Australia

Archaeology in Oceania, EarlyView.
ABSTRACT Shell middens in Gippsland along the eastern half of Victoria's coastline have usually been characterised as small, short‐duration camp sites with relatively low shell densities and low taxonomic diversity. Here we present new excavation results from a dense, high‐diversity site at Red Bluff near the eastern end of GunaiKurnai Country, a ...

Zuranolone: A case study in (regulatory) rush to judgement?

British Journal of Clinical Pharmacology, EarlyView.
Abstract Sage, in collaboration with Biogen, submitted a new drug approval for zuranolone for postpartum depression (PPD) and major depressive disorder (MDD) in December 2022. In August 2023, the US Food and Drug Administration granted approval for PPD but denied approval for MDD.

‘These reforms have teeth’: The affective dimensions of teacher education policy enactment

British Educational Research Journal, EarlyView.
Abstract The affective dimensions of education policy enactment have often received less attention in the research literature, especially regarding teacher education policy. This article reports on a study of the affective responses of university‐based teacher educators in England to the significant initial teacher education reforms of 2019–2022: the ...

Numerical analysis of the skew rolling process for main shafts

Metalurgija, 2015
The paper discusses a new technique of skew rolling with three tapered rolls and its application to the production of long main shafts of steel that are used in light trucks. First, the design of this forming technique is described.

Numerical Simulation as a Tool for the Study, Development, and Optimization of Rolling Processes: A Review

Metals
Rolling is one of the most important processes in the metallurgical industry due to its versatility. Despite its inherent advantages, design and manufacturing by rolling still rely on trial-and-error-based optimizations, which reduces its efficiency.

Dirac Algebroids in Lagrangian and Hamiltonian Mechanics

, 2011
We present a unified approach to constrained implicit Lagrangian and Hamiltonian systems based on the introduced concept of Dirac algebroid. The latter is a certain almost Dirac structure associated with the Courant algebroid on the dual $E^\ast$ to a ...

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
