Real-time precise point positioning performance in Hong Kong during May 2024 space weather events [PDF]

open access: yes
Space weather events are the primary drivers of ionospheric variations. These variations challenge conventional GNSS algorithms’ ionospheric processing strategies, leading to degraded positioning accuracy.

Third‐Party Market Cooperation and Non‐Chinese Multinational Enterprises' Participation in the Belt and Road Initiative in Sub‐Saharan Africa

open access: yesThunderbird International Business Review, Volume 67, Issue 6, Page 665-679, November/December 2025.
ABSTRACT Non‐Chinese multinational enterprises (MNE) are wondering whether China's Belt and Road Initiative (BRI) in Sub‐Saharan Africa (SSA) creates challenges or opportunities for them. The fuzzy term “third‐party market cooperation” was coined to involve non‐Chinese MNEs in BRI‐related business opportunities. Our contribution is threefold: First, we

Breeding for plant‐based proteins in pulse and legume crops: Perspectives, challenges and opportunities

open access: yesCrop Science, Volume 65, Issue 4, July/August 2025.
Abstract The consumption of plant proteins is increasing worldwide as a viable alternative to animal‐derived proteins in the marketplace. The projected increase in global population to at least 10 billion by 2050 is placing greater pressure on the food supply, particularly due to the rising demand for large‐scale protein production.

Review and novel formulae for transmittance and reflectance of wedged thin films on absorbing substrates [PDF]

open access: yes
Historically, spectroscopic techniques have been essential for studying the optical properties of thin solid films. However, existing formulae for both normal transmission and reflection spectroscopy often rely on simplified theoretical assumptions ...

Performance Evaluation of the Dual‐Frequency Ionospheric Free Combination on BDS‐3 Single Point Positioning Accuracy

open access: yesEngineering Reports, Volume 7, Issue 7, July 2025.
Some stations have slightly larger errors in mid low latitude regions, while others have slightly smaller errors in high latitude regions. By comparing the B1C/B2a and B2b/B3I IFC SPP results of all 84 stations, it was found that the RMSE of all stations with B2b/B3I IFC was greater than that of B1C/B2a. ABSTRACT This article analyzes the BDS Phase III

Policy approaches to stimulate exports: The case of Georgia

open access: yesPublic Administration and Development, Volume 44, Issue 3, Page 150-156, August 2024.
Abstract This report examines exporters’ challenges and possible solutions for public intervention to promote foreign trade. Based on fieldwork conducted in Georgia, we explore which policy approaches can help to stimulate Georgian exports further. Our outcomes show that exporters face substantial barriers such as navigating complex trade regulations ...

Does intrinsic motivation or extrinsic pressure matter more? An exploratory study of small businesses going green and innovation

open access: yesBusiness Strategy and the Environment, Volume 33, Issue 5, Page 3855-3886, July 2024.
Abstract Small firms may go green because of intrinsic motivation (to realise their green values) or extrinsic pressure (to satisfy the requirements of stakeholders). While the impacts of these two motivations on firms' green behaviours have been discussed in the literature, their influences on economic behaviours such as innovation remain unclear ...

Effect of Stochastic Modeling for Inter-Frequency Biases of Receiver on BDS-3 Five-Frequency Undifferenced and Uncombined Precise Point Positioning

open access: yesRemote Sensing, 2022
The third generation of the Beidou navigation satellite system (BDS-3) broadcasts navigation signals of five frequencies. Focusing on the deep integration of five-frequency signals, we applied the joint BDS-3 five-frequency undifferenced and uncombined ...
