Dynamics of stochastic SIQS model based on nonlinear incidence: disease extinction and stationary distribution under degenerate diffusion

open access: yesElectronic Research Archive
This paper investigated the dynamical behaviors of the SIQS (susceptible, infected, isolated, and again susceptible) infectious disease model with nonlinear incidence rate and degenerate diffusion in a stochastic environment.

A Scalable, Durable, Fire‐Safe All‐Day Passive Radiative Cooling Coating for Sustainable Buildings

open access: yesAdvanced Functional Materials, EarlyView.
This study reports a scalable, durable coating that combines a fire‑retardant copolymer adhesive, hollow glass microspheres, and boron oxide to achieve passive radiative cooling with over 94% solar reflectance and >95% mid‑infrared emissivity. The coating maintains performance after UV and rain exposure and exhibits UL‑94 V‑0 fire resistance, enabling ...

Full‐Spectrum Solar Harvesting and Desalination Enabled by Supra‐Nano Amorphous Ruthenium Dioxide – Mineral Composites

open access: yesAdvanced Functional Materials, EarlyView.
A mineral‐based supra‐nano amorphous ruthenium dioxide composite (a‐Ru0.5‐AM) was designed, achieving 97% broadband solar absorption. Under one sun, it reaches 87.91 ± 0.32 °C with a distinct thermal buffering effect that favors thermal confinement.

High levels of species' extirpation in an urban environment—A case study from Berlin, Germany, covering 1700–2023

open access: yesEcology and Evolution
Species loss is highly scale‐dependent, following the species–area relationship. We analysed spatio‐temporal patterns of species' extirpation on a multitaxonomic level using Berlin, the capital city of Germany.

Wafer‐Scale Synthesis of Mithrene and its Application in UV Photodetectors

open access: yesAdvanced Functional Materials, EarlyView.
A controlled tarnishing step on the silver surface precedes the solid‐vapor‐phase chemical transformation into silver phenylselenolate thin films. The approach yields crystals exceeding 1 µm with improved in‐plane orientation. Integration on graphene phototransistors demonstrates high photoresponsivity, positioning mithrene as a promising material for ...

Humidity modifies species‐specific and age‐dependent heat stress effects in an insect host‐parasitoid interaction

open access: yesEcology and Evolution
Climate change is projected to increase the frequency and intensity of extreme heat events, and may increase humidity levels, leading to coupled thermal and hydric stress.

Transmission dynamics of symptom-dependent HIV/AIDS models

open access: yesMathematical Biosciences and Engineering
In this study, we proposed two, symptom-dependent, HIV/AIDS models to investigate the dynamical properties of HIV/AIDS in the Fujian Province. The basic reproduction number was obtained, and the local and global stabilities of the disease-free and ...

Unveiling Aggregation‐Induced Singlet Fission in Push–Pull Diketopyrrolopyrrole Water Dispersed Nanoaggregates and Thin Films

open access: yesAdvanced Functional Materials, EarlyView.
Aggregates of diketopyrrolopyrrole dipolar and quadrupolar systems exhibit panchromatic absorption spectra extending in the entire visible range. Upon aggregation in water and in the solid state, their fluorescence is almost completely quenched and their singlet excited state lifetime is significantly shortened.
