Modelling the Four‐Dimensional Power Line Sag Dynamics by Point Signature in Time‐Series Synthetic‐Aperture Radar Images

open access: yesHigh Voltage, EarlyView.
ABSTRACT Power lines in synthetic‐aperture radar (SAR) images are reflected as point signatures, which fluctuate annually in both the azimuth and range directions. A novel framework is proposed in this paper to evaluate the four‐dimensional dynamic status of power line sag using those point signatures in time‐series SAR images.

Is the rent too high? Land ownership and monopoly power

open access: yesReal Estate Economics, EarlyView.
Abstract Pricing power in real estate markets can reduce housing supply and redevelopment relative to the social optimum. We show how pricing power interacts with popular redevelopment subsidies and zoning regulations. Using building‐level rental income data from NYC, we find that increased concentration is correlated with increased rents.

The company you keep: The influence of popular delinquents and deviant brokers on offending trajectories

open access: yesCriminology, EarlyView.
Abstract Research on how delinquent peer associations affect individuals’ life courses is limited. This paper addresses this gap by examining delinquent peer network characteristics and their impact on offending trajectories through social network analysis (SNA) and group‐based trajectory modeling (GBTM).

RAPID: Real‐time animal pattern re‐identification on edge devices, an open‐source tool for field deployment

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Automatic re‐identification of animals has significant potential to address pressing ecological and conservation challenges through improved population monitoring, individual health assessment and detailed behavioural analyses. Although numerous computer‐vision‐based solutions have been proposed and many achieve high accuracy, most remain ...

A Threat‐Scoring Framework Using Crowdsourced Data Indicates High Threat Levels in Fossorial Shieldtail Snakes

open access: yesAnimal Conservation, EarlyView.
Reliable estimates of species distributions are crucial for understanding their conservation needs. Yet for many species, IUCN largely relies on expert‐drawn ranges, which are often inaccurate. Focusing on shieldtail snakes in peninsular India, we combined citizen science, literature, field, and museum records to create improved distribution maps for ...

Geometric Linearization of Ordinary Differential Equations

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2007
The linearizability of differential equations was first considered by Lie for scalar second order semi-linear ordinary differential equations. Since then there has been considerable work done on the algebraic classification of linearizable equations and ...

Automating Archaeological Discovery: Assessing Geospatial Artificial Intelligence (GeoAI) Tools for Stone Wall Identification in Kweneng, South Africa

open access: yesArchaeometry, EarlyView.
ABSTRACT The discovery of archaeological sites traditionally entails the utilisation of physically demanding exploration methodologies, including terrain surveying and the analysis of historical records. Recent technological developments have led to an increased use of non‐invasive remote sensing techniques, including Google Earth, LiDAR and aerial ...

Geodesics in conical manifolds [PDF]

open access: yes, 2005
The aim of this paper is to extend the definition of geodesics to conical manifolds, defined as submanifolds of Rn with a finite number of singularities.

A tutorial on Bayesian model averaging for exponential random graph models

open access: yesBritish Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract The use of exponential random graph models (ERGMs) is becoming prevalent in psychology due to their ability to explain and predict the formation of edges between vertices in a network. Valid inference with ERGMs requires correctly specifying endogenous and exogenous effects as network statistics, guided by theory, to represent the network ...
