Seasonal Dynamics of Soil Multitrophic Biodiversity, Co‐Occurrence Network and Assembly Mechanisms Under Typical Vegetation Restoration Patterns in Karst Region

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Previous studies often overlooked the dynamic effects of karst vegetation restoration on soil multi‐trophic biodiversity and the underlying community‐assembly mechanisms. To fill this gap, we performed a seasonal comparative analysis of soil biodiversity, co‐occurrence network architecture, and assembly processes across three representative ...

Homomorphisms and amalgamation

open access: yesDiscrete Mathematics, 2003
A graph \(G\) is called core if each homomorphism \(G \to G\) is an automorphism of \(G\). A graph \(H\) is called \(G\)-colourable if there is a homomorphism \(H \to G\). The author proves that if \(G\) is a finite core, then the class of \(G\)-colourable graphs is a pseudo-amalgamation class in the sense of \textit{R.

Characterization of Dental Composite Resin with Additional TiO2 Nanoparticle Filler

open access: yesMacromolecular Symposia, EarlyView.
Silanized SiO2‐based dental composite resins with and without TiO2 nanoparticle addition were fabricated using a Bis‐GMA/TEGDMA resin matrix and photopolymerized under 468‐470 nm UV light. The resulting composites, composite I (55% SiO2) and composite II (50% SiO2 + 5% TiO2), were characterized via scanning electron microscopy (SEM), Fourier transform ...

Placebo Effect in Levodopa‐Induced Dyskinesia: A Systematic Review and Meta‐Analysis

open access: yesMovement Disorders Clinical Practice, EarlyView.
Abstract Background Levodopa‐induced dyskinesia (LID) is a complication of Parkinson's disease (PD) treatment. While the placebo effect is a known component in PD clinical trials, its specific magnitude in the context of LID is not well characterized.

It’s not amalgam, it is white amalgam

open access: yesThe Saudi Dental Journal, 2019
Introduction: A new class of restorative GIC, named Zirconomer, with increased strength and durability has been developed. It shows strength of amalgam, so it is also called white amalgam. Inclusion of zirconia fillers reinforces the structural integrity of that material, imparts its outstanding posterior esthetics, completely eliminates mercury ...

Computational Analysis of the Vibrational Response of Lunar Regolith Made of Nonspherical Grains

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Vibration‐based systems have shown that appropriately oriented and tuned mechanical oscillations can disrupt regolith interlocking and promote flow. Building on this evidence, the present study investigates vibration‐controlled granular discharge as a potential ISRU (In Situ Resource Utilization) strategy, with the aim of supporting ...
