Does Twin Transition Facilitate Exporting? The Case of Logistics Innovation

open access: yesBusiness Strategy and the Environment, Volume 34, Issue 7, Page 8194-8212, November 2025.
ABSTRACT Firms need to overcome two hurdles to enter foreign markets: deciding whether to export and the intensity of their export sales. Although logistics plays a crucial role in exporting, the link between logistics innovation and exporting remains unexplored.

Fast semidifferential-based submodular function optimization [PDF]

open access: yes, 2013
We present a practical and powerful new framework for both unconstrained and constrained submodular function optimization based on discrete semidifferentials (sub- and super-differentials).

Target Return Strategy

open access: yesFinancial Review, Volume 60, Issue 4, Page 1483-1503, November 2025.
ABSTRACT We study the target return strategy (TRS), which exits the market once the return reaches a preset target. We show that the holding‐period return (HPR) cannot mean‐variance dominate TRS, but TRS can mean‐variance dominate HPR. We theoretically analyze TRS and quantitatively illustrate that training targets by a mean‐variance utility ...

Low-Delay and High-Coverage Water Distribution Networks Monitoring Using Mobile Sensors

open access: yesIEEE Access, 2019
Urban water distribution networks (WDNs) are usually threatened by leakage, reflux, infiltration and internal pollution. To ensure the safety of water supply, it is essential to properly monitor the WDNs.

Assessing Large Multimodal Models for One‐Shot Learning and Interpretability in Biomedical Image Classification

open access: yesAdvanced Intelligent Systems, Volume 7, Issue 10, October 2025.
Image classification plays a pivotal role in biomedical image analysis. Herein, it is shown that large multimodal models, such as GPT‐4, achieve superior performance in one‐shot learning, generalization, interpretability, and text‐driven image classification. Applications span tissue, cell type, cellular state, and disease classification, outperforming

Differentially Private Online Submodular Optimization

open access: yesCoRR, 2018
In this paper we develop the first algorithms for online submodular minimization that preserve differential privacy under full information feedback and bandit feedback. A sequence of $T$ submodular functions over a collection of $n$ elements arrive online, and at each timestep the algorithm must choose a subset of $[n]$ before seeing the function.
