Amanita theophili sp. nov. (Amanitaceae) from central Mexico

Nordic Journal of Botany, EarlyView.
Amanita theophili sp. nov., a member of Amanita sect. Amidella (Amanitaceae), is described from temperate pine‐oak forests in Morelos, central Mexico. Morphological features and phylogenetic analyses based on ITS and 28S rDNA sequences confirm its distinct taxonomic status. The new species is morphologically similar to A. peckiana and A.

Dynamical Sampling with Langevin Normalization Flows

Entropy, 2019
In Bayesian machine learning, sampling methods provide the asymptotically unbiased estimation for the inference of the complex probability distributions, where Markov chain Monte Carlo (MCMC) is one of the most popular sampling methods. However, MCMC can

Environmental influence on intraspecific trait variation in the tropical seagrass Halodule uninervis

Oikos, EarlyView.
Intraspecific trait variation (ITV) enhances the precision of applying functional trait approaches in plant ecology. Despite its benefits, ITV is rarely considered in functional trait‐based seagrass research. The goal of our research is to measure ITV in the tropical seagrass species Halodule uninervis and assess the environmental factors associated ...

A Robust Non-Gaussian Data Assimilation Method for Highly Non-Linear Models

Atmosphere, 2018
In this paper, we propose an efficient EnKF implementation for non-Gaussian data assimilation based on Gaussian Mixture Models and Markov-Chain-Monte-Carlo (MCMC) methods.

Connecting the distribution and diversification of marine plants

Oikos, EarlyView.
Integration of the evolutionary history with distribution of extant species is necessary to explain present‐day diversity, particularly for ‘foundation' species, such as seagrasses, which create habitats of socioecological relevance. Here, we resolved if varying evolutionary history of seagrass families has imprinted the distribution ranges of extant ...

A Markov Chain Monte Carlo Procedure for Efficient Bayesian Inference on the Phase-Type Aging Model

Stats
The phase-type aging model (PTAM) belongs to a class of Coxian-type Markovian models that can provide a quantitative description of well-known aging characteristics that are part of a genetically determined, progressive, and irreversible process.

Beyond our backyard: Unravelling how social‐ecological fit drives the formation of inter‐regional collaborative networks for water governance in the Yellow River Basin

People and Nature, EarlyView.
Abstract The societal and biophysical permeability across human‐demarcated jurisdictions within watersheds necessitates collaboration among administrative regions. The effectiveness of such collaboration is partly determined by the degree to which institutional arrangements align with underlying social and ecological interdependencies, a concept ...

A Facile Salt‐Assisted Dewatering for Carboxymethyl Cellulose‐Based Hydrogels

Polymer Engineering &Science, EarlyView.
Dehydration efficiency of hydrogels increases with NaCl concentration during washing. ABSTRACT Natural polymer‐based hydrogels are gaining attention as an environmentally friendly alternative to petroleum‐based superabsorbent polymers. The hydrogel fabrication process involves washing and drying hydrated gels. However, due to their high hydrophilicity,

Range‐wide sampling reveals cryptic lineages but largely conserved mycorrhizal associations in the Japanese fairy lantern Thismia kobensis

PLANTS, PEOPLE, PLANET, EarlyView.
The jewel‐like flowers of Thismia are as rare as they are beautiful, often recorded from only a single site per species. Access to 15 populations of T. kobensis has enabled an uncommon, range‐wide assessment of morphology, genetics, and fungal partners. Our analyses showed that T.

A Multi-Function Common Mode Choke Based on Active CM EMI Filters for AC/DC Power Converters

IEEE Access, 2019
It is widely believed that hybrid electromagnetic interference (EMI) filter (HEF) is one of the most optimized solutions for EMI elimination. Nevertheless, the desire for a smaller and lighter filtering method has never stopped.
