Influence of rubbing during etching on surface roughness and interfacial characteristics of intact enamel

open access: yesEuropean Journal of Oral Sciences, EarlyView.
Abstract Rubbing phosphoric acid during etching has been shown to improve surface roughness in prepared enamel. This study aimed to compare intact enamel's surface roughness and resin tag lengths after etching with and without rubbing. Extracted sound third molars were used for testing, mesially for conventional and distally for dynamic (rubbing ...

Seeing the Forest–Communities–Trees: Exploring the Impact of Industry Agglomerations on Technological Innovations and Firm Performance within Ecosystems

open access: yesJournal of Management Studies, EarlyView.
Abstract Drawing on agglomeration theory, embeddedness theory, and the community assembly metaphor, this study examines how regional industrial ecosystems (RIEs) shape firm performance in China's manufacturing sector. Using longitudinal data on 1012 listed manufacturing firms across China between 2008 and 2019, we combine input–output analysis with ...

The determination of what is said and what is implied

open access: yesMind &Language, EarlyView.
Is what is said determined by syntax, conventional meaning, and select aspects of context? This thesis—semanticity—seems plausible because what is said can diverge from both what the speaker means and what the addressee understands, and because ordinary speakers know what is said when presented with a novel sentence‐context pair.

Machine‐Learning Surrogate Modeling of RbGeI3 Perovskite Solar Cells: Global Sensitivity Analysis and the Limits of Surrogate‐Guided Optimization

open access: yesAdvanced Computing, Volume 1, Issue 1, December 2026.
Surrogate model of an RbGeI3 solar cell trained on 4396 SCAPS‐1D simulations. Defect density dominates the efficiency variance; the gap between total‐order and first‐order Sobol indices reveals parameters acting only through interactions. ABSTRACT Here, a machine‐learning surrogate is developed for an FTO/TiO2/RbGeI3/Spiro‐OMeTAD/Au configuration from ...

Chemical Characterisation of Steam‐Distilled Essential Oils From Lemongrass (Cymbopogon citratus Stapf) and Ginger Rhizomes (Zingiber officinale Roscoe) Using FTIR and GC‐MS: Comparison of Phytochemical Composition

open access: yesPhytochemicals in Food and Medicine, Volume 1, Issue 4, December 2026.
Illustration of essential oil extraction coupled with characterisation. ABSTRACT Essential oils from lemongrass and ginger rhizomes contain bioactive compounds with potential for nutraceutical and pharmaceutical applications. In this study, essential oils were extracted from ginger rhizomes and lemongrass by the steam distillation method, using a ...

Random Turán Problems for Hypergraph Expansions

open access: yesRandom Structures &Algorithms, Volume 69, Issue 4, December 2026.
ABSTRACT Given an r0$$ {r}_0 $$‐uniform hypergraph F$$ F $$, we define its r$$ r $$‐uniform expansion F(r)$$ {F}^{(r)} $$ to be the hypergraph obtained from F$$ F $$ by inserting r−r0$$ r-{r}_0 $$ distinct vertices into each edge of F$$ F $$, and we define ex(Gn,pr,F(r))$$ \mathrm{ex}\left({G}_{n,p}^r,{F}^{(r)}\right) $$ to be the largest F(r)$$ {F ...

Identification of Local Performance Losses in Perovskite Solar Cells Through Coupled Luminescence Imaging and Physics‐Based Statistical Modelling

open access: yesSolar RRL, Volume 10, Issue 21, 16 November 2026.
Coupled photoluminescence and electroluminescence imaging with multiphysics‐based statistical modelling enables quantitative diagnosis of local performance losses in perovskite solar cells. The approach identifies the physical origins of nonuniformities by distinguishing loss mechanisms and extracting the underlying physical parameters, transforming ...
