Exact and metaheuristic approaches to minimizing makespan in parallel machine scheduling with conflicting jobs

International Transactions in Operational Research, EarlyView.
Abstract We address the scheduling conflicting jobs on parallel identical machines problem with makespan minimization, a classical and computationally challenging variant of parallel machine scheduling. We develop and evaluate three distinct solution methodologies: a novel constraint programming (CP) formulation, and two metaheuristics: a multi ...

Managerial Overoptimism and Discretionary Disclosure

Journal of Business Finance &Accounting, EarlyView.
ABSTRACT We examine the effect of managerial overoptimism on discretionary disclosure of subjective information, such as earnings forecasts. The market applies a discount upon disclosure to capture the possibility that the revealed subjective expectation is too optimistic.

Evidence Gathering Under Competitive and Noncompetitive Rewards

Journal of Economics &Management Strategy, EarlyView.
ABSTRACT Reward schemes may affect not only agents' effort but also their incentives to gather information in order to reduce the riskiness of the productive activity. In a laboratory experiment using a novel task, we find that the relationship between incentives and evidence gathering depends critically on the availability of information about peers ...

Unambiguous acquisition algorithm based on sub‐correlation functions combination for semi‐integer CPM signals

Electronics Letters
Due to the nonlinear nature of continuous phase modulation (CPM), most existing unambiguous acquisition algorithms are ineffective in eliminating the ambiguity threat faced by semi‐integer CPM signals.

Overview of development and challenges of attitude determination for rotary wing UAVs based on GNSS

Frontiers in Physics
Attitude determination of rotary-wing unmanned aerial vehicles (RUAVs) is crucial for grasping their motion state and is a necessary condition to ensure the correct execution of flight missions.

Leveraging modified ex situ tomography data for segmentation of in situ synchrotron X‐ray computed tomography

Journal of Microscopy, EarlyView.
Abstract In situ synchrotron X‐ray computed tomography enables dynamic material studies. However, automated segmentation remains challenging due to complex imaging artefacts – like ring and cupping effects – and limited training data. We present a methodology for deep learning‐based segmentation by transforming high‐quality ex situ laboratory data to ...

Selection in car insurance when claims are heterogeneous

Journal of Risk and Insurance, EarlyView.
Abstract Econometric studies of insurance markets have analyzed the Positive Correlation Property to test for the presence of asymmetric information. Car‐insurance studies frequently compare policies purchasing Mandatory Third‐Party Liability alone with policies that purchase additional coverage and use the presence of a liability claim as a measure of

Orbit and clock products for quad-system satellites with undifferenced ambiguity fixing approach

Satellite Navigation
Integer Ambiguity Resolution (IAR) can significantly improve the accuracy of GNSS Precise Orbit Determination (POD). Traditionally, the IAR in POD is achieved at the Double Differenced (DD) level.

Functional Vašiček Model

Journal of Time Series Analysis, EarlyView.
ABSTRACT We propose a new formulation of the Vašičekmodel within the framework of functional data analysis. We treat observations (continuous‐time rates) within a suitably defined trading day as a single statistical object. We then consider a sequence of such objects, indexed by day.

Language comprehension and the rhythm of perception

Mind &Language, EarlyView.
It is widely agreed that language understanding has a distinctive phenomenology, as illustrated by phenomenal contrast cases. Yet it remains unclear how to account for the perceptual phenomenology of language experience. I advance a rhythmic account, which explains this phenomenology in terms of changes in the rhythm of sensory capacities in both ...
