A reconstructed Pangea would result in lower biodiversity

open access: yesOikos, EarlyView.
Driven by globalization and climatic change, rates of biological invasion are on the increase. Although these increasing rates are widely expected to lead to increased rates of extinction, it has been argued that these ‘newly arrived' species might increase biodiversity.

Mechanical Properties of Hybrid Natural Fiber–Carbon Fiber‐Reinforced Polypropylene Nonwoven Composites: Influence of Degree of Densification, Fiber Volume Fraction and Laminate Architecture

open access: yesPolymer Composites, EarlyView.
Reinforcement where it matters: from a homogenious fiber‐reinforced part to a load‐adapted hybrid molded composite part. ABSTRACT Nonwoven composites based on flax fiber (NF)‐reinforced polypropylene (PP) offer a promising route toward sustainable lightweight structures but are limited by moderate mechanical performance.

The evaluation of boundary‐layer turbulence in high‐resolution numerical weather prediction simulations using Doppler lidar

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
A new method compares both kilometer and sub‐kilometre weather model simulations with Doppler lidar observations to assess the representation of boundary‐layer turbulence. While bulk boundary‐layer properties are well represented, vertical velocity variance is strongly underestimated in both simulations.

Multiscale controls on diurnal convection in the Maritime Continent: Insights from high‐resolution observations in Timika

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Across the Maritime Continent, diurnal rainfall variability is governed by interactions between regional‐scale atmospheric drivers and local land–sea breeze circulations. Afternoon convection is initiated over land by surface heating and propagates offshore, whereas morning rainfall develops over adjacent seas and moves inland under low‐level northerly

On the Total Version of Triple Roman Domination in Graphs

open access: yes
In this paper, we describe the study of total triple Roman domination. Total triple Roman domination is an assignment of labels from (Formula presented.) to the vertices of a graph such that every vertex is protected by at least three units either on ...

Mapping Scytonemin Pigment Content and Biocrust Functional Indicators Using High‐Resolution Multispectral Imagery

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
We demonstrate that high‐resolution multispectral imagery combined with machine learning can accurately predict key biocrust functional indicators, particularly the UV‐protective pigment scytonemin, across dryland ecosystems. Using fine‐scale imagery acquired in the Chihuahuan Desert and Colorado Plateau, we identified spectral bands strongly ...

Signed double Roman k-domination in digraphs

open access: yes
Let D be a finite simple digraph with vertex set V(D), and let k≥1 be an integer. A signed double Roman k-dominating function (SDRkDF) on a digraph D is a function f: V(D) → {-1,1,2,3} satisfying certain conditions.
