recommendations! Published in 2017 at "Journal of Geophysical Research"

DOI: 10.1002/2016ja023027

Abstract: The Abel inversion of ionospheric electron density profiles with the assumption of spherical symmetry applied for radio occultation soundings could introduce a greater systematic error or sometimes artifacts if the occultation rays trespass regions with… read more here.

DOI: 10.1002/2017jb014738

Abstract: The sources of ambient seismic noise are extensively studied both to better understand their influence on ambient noise tomography and related techniques, and to infer constraints on their excitation mechanisms. Here we develop a gradient-based… read more here.

DOI: 10.1002/adfm.202312831

Abstract: Photonics and tunable optics are rapidly developing fields that require materials with programmable properties and advanced functionalities. Cholesteric liquid crystals (CLCs) are unique materials that exhibit selective light reflection and can be tuned using stimuli‐responsive… read more here.

DOI: 10.1002/asjc.70002

Abstract: This study is concerned with the issue of solving the discrete periodic Riccati matrix equations (DPREs) in discrete‐time periodic linear systems. Currently, many existing results for solving the DPRE involve matrix inversion operations. In order… read more here.

recommendations! Published in 2019 at "Ecology and Evolution"

DOI: 10.1002/ece3.5094

Abstract: Abstract Inversions may contribute to ecological adaptation and phenotypic diversity, and with the advent of “second” and “third” generation sequencing technologies, the ability to detect inversion polymorphisms has been enhanced dramatically. A key molecular consequence… read more here.

DOI: 10.1002/ejoc.202400015

Abstract: Developing aggregation‐induced emission luminogens (AIEgens) is a unique strategy for alleviating concentration quenching of π‐conjugated organic compounds. This AIE behaviour can be induced not only in organic dyes with rotors but also in invertible π‐conjugated… read more here.

recommendations! Published in 2025 at "Limnology and Oceanography"

DOI: 10.1002/lno.70053

Abstract: Periphyton plays an important functional role in shallow lakes and is sensitive to variation in nutrient availability and global warming. Understanding the responses of periphyton to changes in nutrient availability in contrasting warming scenarios can… read more here.

recommendations! Published in 2022 at "Macromolecular rapid communications"

DOI: 10.1002/marc.202200238

Abstract: In general, a single enantiomer can induce a foldamer into a preferred-handed helix, while another condition is required for the helical inversion. In this work, it is found that the helix induction and subsequent inversion… read more here.
