Multi‐Task Learning for Airport Surface Surveillance: A Review

open access: yesExpert Systems, Volume 43, Issue 4, April 2026.
ABSTRACT The rapid growth of air transportation has surpassed the capabilities of traditional airport surveillance methods, such as visual observation and auxiliary equipment (e.g., ADS‐B, MLAT, radar), which struggle to provide all‐area, all‐weather situation awareness.

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

open access: yesAdvanced Intelligent Systems, Volume 8, Issue 3, March 2026.
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.

Reserve Price Signaling With Public Information: Evidence From Online Auto Auctions

open access: yesThe RAND Journal of Economics, Volume 57, Issue 1, Page 245-266, Spring 2026.
ABSTRACT This article considers an auction model in which a seller's choice of reserve price signals her private information about the object's quality. We show that the signaling incentive would lower the seller's payoff and the probability of sale. We estimate the model using a novel dataset from a large online auto auction platform.
