Earth and Space Science, Volume 10, Issue 12, December 2023., 2023 Abstract A spectral deconvolution model (SDM) for inversion of light absorption, a(λ) and backscattering, bb(λ), to estimate concentrations of chlorophyll (CHL), colored dissolved organic material (CDOM) and non‐biogenic mineral suspended solids (MSS) in offshore and shelf waters is presented. This approach exploits the spectral information embedded in

Variations in Physiology and Genomic Function of Prochlorococcus Across the Eastern Indian Ocean
Journal of Geophysical Research: Oceans, Volume 128, Issue 10, October 2023., 2023 Abstract The widespread distribution of Prochlorococcus can be attributed to the extensive genetic diversity that allows them to adapt to various oligotrophic environments. We investigated the adaptation of Prochlorococcus to nutrient environments in the surface eastern Indian Ocean (EIO, 16.5°N to 20°S, 88°E) in November 2018.

On the numerical properties of high‐order spectral (Euler‐Bernoulli) beam elements
ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, Volume 103, Issue 9, September 2023., 2023 In this paper, the numerical properties of a recently developed high‐order Spectral Euler‐Bernoulli Beam Element (SBE) featuring a C1‐continuous approximation of the displacement field are assessed. The C1‐continuous shape functions are based on two main ingredients, which are an Hermitian interpolation scheme and the use of Gauß‐Lobatto‐Legendre (GLL)

Cone‐equivalent nilpotent groups with different Dehn functions
Proceedings of the London Mathematical Society, Volume 126, Issue 2, Page 704-789, February 2023., 2023 Abstract For every k⩾3$k\geqslant 3$, we exhibit a simply connected k$k$‐nilpotent Lie group Nk$N_k$ whose Dehn function behaves like nk$n^k$, while the Dehn function of its associated Carnot graded group gr(Nk)$\mathsf {gr}(N_k)$ behaves like nk+1$n^{k+1}$. This property and its consequences allow us to reveal three new phenomena.

Bayesian models for spatially explicit interactions between neighbouring plants
Methods in Ecology and Evolution, Volume 13, Issue 12, Page 2788-2798, December 2022., 2022 Abstract Interactions between neighbouring plants drive population and community dynamics in terrestrial ecosystems. Understanding these interactions is critical for both fundamental and applied ecology. Spatial approaches to model neighbour interactions are necessary, as interaction strength depends on the distance between neighbouring plants.

Efficient Inverse Model for Cloud Computing and Information Based on the Symmetric Random Matrix
Mathematical Problems in Engineering, Volume 2022, Issue 1, 2022., 2022 With the continuous development of cloud storage technology, cloud storage has become a new way of storage for both enterprises and individuals. The cloud environment can support users to share data, but it can lead to some malicious users accessing or modifying data by illegal means, so access control is an important way to protect user data.

Human Brain Mapping, Volume 42, Issue 14, Page 4580-4596, October 1, 2021., 2021 In the present study, Xia et al. demonstrate that advanced paternal age at childbirth (PatAGE) is negatively associated with offspring's reading. Moreover, this association is mediated by neuroanatomical maturation in the left posterior thalamus, which is closely linked with the dorsal attention network.

Data Integration by Combining Big Data and Survey Sample Data for Finite Population Inference
International Statistical Review, Volume 89, Issue 2, Page 382-401, August 2021., 2021 Summary The statistical challenges in using big data for making valid statistical inference in the finite population have been well documented in literature. These challenges are due primarily to statistical bias arising from under‐coverage in the big data source to represent the population of interest and measurement errors in the variables available ...

Mobile Information Systems, Volume 2021, Issue 1, 2021., 2021 To process a huge amount of data, computing resources need to be organized in clusters that can be scaled out easily. Still, traditional SQL databases built on the relational data model are difficult to be put to use in such clusters, which has motivated the movement named NoSQL. However, NoSQL databases have their limits by using their own data models.

Inherent Optical Properties‐Reflectance Relationships Revisited
Journal of Geophysical Research: Oceans, Volume 125, Issue 11, November 2020., 2020 Abstract Understanding the relationship between remote sensing reflectance, Rrs(λ) and the inherent optical properties (IOPs) of natural waters is potentially a key to improving our ability to determine biogeochemical constituents from radiometric measurements.
