Estimation of BDS-2/3 phase observable-specific signal bias aided by double-differenced model: an exploration of fast BDS-2/3 real-time PPP

GPS Solutions
GNSS phase observable-specific signal bias (OSB) corrections are essential for widespread application of precise point positioning with ambiguity resolution (PPP-AR) or PPP-RTK.

A Principal-Agent Theory Perspective on PPP Risk Allocation

Sustainability, 2019
This study proposes a framework for the allocation of risk in public private partnerships (PPP) projects. Its contribution lies in the recognition and incorporation of risks introduced by project stakeholders, and as articulated by the principal-agent ...

Circadian‐Related Serotonin/Melatonin Level Modulates Cisplatin Ototoxicity Susceptibility Depended on NOS3–NO Pathway

Journal of Pineal Research, Volume 78, Issue 4, July 2026.
ABSTRACT Hearing impairment is attributed to factors such as age, genetic predisposition, and environmental influences, among which environmental factors are considered modifiable. Among various environmental factors, the role of poor lifestyle habits is particularly critical, yet the specific mechanisms by which they contribute to hearing damage ...

Performance Analysis of Multi-GNSS Real-Time PPP-AR Positioning Considering SSR Delay

Remote Sensing
For real-time (RT) precise point positioning (PPP), the state space representation (SSR) information is often delayed due to possible communication delays and specific broadcast intervals.

Flexibility in PPP contracts – Dealing with potential change in the pre-contract phase of a construction project

, 2017
Public Private Partnerships (PPPs) cover a range of possible relationships between public and private parties. PPP contracts are typically used in contexts of great uncertainty, such as large construction and infrastructure projects that are realized ...

Contextualized Metabolic Modelling Revealed Factors Affecting Isoflavone Accumulation in Soybean Seeds

Plant, Cell &Environment, Volume 49, Issue 7, Page 3543-3559, July 2026.
ABSTRACT Isoflavones, secondary metabolites with numerous health benefits, are predominantly found in legume seeds, especially soybean; however, their contents in domesticated soybean seeds are highly variable. Wild soybeans are known for higher seed isoflavone contents than cultivars. Here we used experimental and modelling approaches on wild soybean (

Trends in Structural and Spectroscopic Signatures of Iron(II) Complexes Supported by Systematically Varied Tetra‐N‐Heterocyclic Carbene Macrocycles

European Journal of Inorganic Chemistry, Volume 29, Issue 17, 17 June 2026.
The effects of ligand ring size and peripheral substitution on geometric and electronic structures as well as electrochemical and spectroscopic properties of a family of iron(II) complexes with macrocyclic tetracarbene ligands, often called organometallic heme analogues, have been analyzed, to provide structure/property correlations as a basis for ...

GNSS Real-Time ZTD/PWV Retrieval Based on PPP with Broadcast Ephemerides

Atmosphere
GNSS precise point positioning (PPP) plays an important role in retrieving atmospheric water vapor values and performing numerical weather prediction. However, traditional PPP relies on real-time orbits and clocks, which require continuous internet or ...

Phytochemical Profiling, Antiplatelet Potential, and Cytotoxic Assessment of Thymelaea tartonraira Aerial Part Essential Oil: In Vitro and In Silico Studies

Chemistry &Biodiversity, Volume 23, Issue 6, June 2026.
Essential oil from Thymelaea tartonraira was characterized by GC–MS and evaluated using in vitro and in silico approaches. The oil exhibited notable antiplatelet activity with low cytotoxicity. Molecular docking revealed strong interactions of major compounds with GPVI, COX‐1, and P2Y12, supporting its potential as a natural antiplatelet agent ...
