Motive and Opportunity: Order Choice in a Limit Order Book With Dispersed Information

open access: yesInternational Journal of Finance &Economics, EarlyView.
ABSTRACT We test predictions of market microstructure theory relating to the determinants of order choice in a limit order book where information is dispersed among traders. Using an experimental limit order book, with a large state space, we find that informed traders exhibit patience, compatible with the ‘waiting game’ behaviour described in Foster ...

A Joint Test of Unconfoundedness and Common Trends

open access: yesJournal of Applied Econometrics, EarlyView.
ABSTRACT We introduce an overidentification test of two alternative assumptions to identify the average treatment effect on the treated in a two‐period panel data setting: unconfoundedness and common trends. Under unconfoundedness, treatment assignment and post‐treatment outcomes are independent, conditional on control variables and pre‐treatment ...

Linear Versus Centred Colouring via Pseudogrids

open access: yesJournal of Graph Theory, EarlyView.
ABSTRACT A centred colouring of a graph is a vertex colouring in which every connected subgraph contains a vertex whose colour is unique and a linear colouring is a vertex colouring in which every (not‐necessarily induced) path contains a vertex whose colour is unique. For a graph G $G$, the centred chromatic number χ cen ( G ) ${\chi }_{\text{cen}}(G)$

Reliable GPS Integer Ambiguity Resolution. [PDF]

open access: yes, 2011
To operate, guide and control vehicles in low visibility conditions, it is critical that the states of the vehicle are accurately estimated, which includes the three dimensional position, velocity, and attitude. This can be accomplished by GPS (Global Positioning System) aided encoder or GPS aided inertial approaches.

You, Me, and the AI: The Role of Third‐Party Human Teammates for Trust Formation Toward AI Teammates

open access: yesJournal of Organizational Behavior, EarlyView.
ABSTRACT As artificial intelligence (AI) becomes increasingly integrated in teams, understanding the factors that drive trust formation between human and AI teammates becomes crucial. Yet, the emergent literature has overlooked the impact of third parties on human‐AI teaming.

Business Process Management Maturity and Digital Transformation: Evidence From a Financial Institution in an Emerging Economy

open access: yesKnowledge and Process Management, EarlyView.
ABSTRACT This study examines how business process management (BPM) maturity shapes digital transformation in a large financial institution operating in a highly regulated, emerging‐economy context. Drawing on a qualitative single case study, the research applies Rosemann and De Bruin's BPM Maturity Model to analyse how different maturity dimensions ...

Research on GPS geometry-based observational stochastic error model

open access: yesTongxin xuebao, 2019
Aiming at the problem of not enough influencing factors were considered in traditional methods,a much more realistic stochastic model was built.In which error corrections were introduced into the geometry-based function model,an improved least squares ...

The Two Extremal Rays of Some Hyper–Kähler Fourfolds

open access: yesMathematische Nachrichten, EarlyView.
ABSTRACT We consider projective Hyper–Kähler manifolds of dimension 4 that are deformation equivalent to Hilbert squares of K3 surfaces. In case such a manifold admits a divisorial contraction, the exceptional divisor is a conic bundle over a K3 surface. A classification of lattice embeddings implies that there are five types of such conic bundles.

Machine Learning Prediction of Hoehn and Yahr Scores at 5‐Years Post‐123I‐Ioflupane SPECT Imaging in a Real‐World Parkinson's Disease Dataset

open access: yesMovement Disorders Clinical Practice, EarlyView.
Abstract Background Parkinson's disease (PD) progression is highly heterogeneous, complicating clinical management and prognostication. While machine learning models have been developed using research datasets such as Parkinson's Precision Medicine Initiative (PPMI) and Parkinson's Disease Biomarkers Program (PDBP), their clinical translatability is ...
