Performance of Modified Natural Zeolites by Sodium Hydroxide Treatments in The Esterification of Glycerol and Oleic Acid

open access: yesJurnal Kimia Valensi, 2019
Esterification is the reaction of the formation of an ester compound by reacting an alcohol compound and carboxylic acid. In this study, the performance of zeolite-based catalysts has been studied for esterification reactions.

The Maltese nobility during the Hospitaller period : towards a reappraisal [PDF]

open access: yes, 2011
Over the last thirty years the nobilities of early modern Europe have become a subject of major interest for historians working on the social history of the period. This increase in attention has resulted in the development of new approaches to what is

XAI‐Supported Dynamics of Civil Aircraft Trajectory: Energy Conservation in Point Mass Modeling With Comparative Analysis

open access: yesJournal of Engineering, Volume 2026, Issue 1, 2026.
Precise aircraft trajectory prediction is a critical issue in civil aviation. Traditional dynamics analysis using the classical point mass model often encounters deviations due to inaccuracies in aircraft mass estimation, which can ultimately undermine the validity of the energy conservation equation.

Quenched and first unquenched lattice HQET determination of the Bs-Meson width difference [PDF]

open access: yes, 2000
We present recent results for the prediction of the Bs lifetime difference from lattice Heavy Quark Effective Theory simulations. In order to get a next-to-leading order result we have calculated the matching between QCD and HQET and the two-loop ...

A Biofunctional Hydrogel/Nanofiber Bilayer Scaffold Delivering EGF and TGFβ3 for Advanced Nasal Tissue Reconstruction

open access: yesMacromolecular Materials and Engineering, Volume 310, Issue 12, December 2025.
This study develops a biomimetic bilayer scaffold based on gelatin methacryloyl‐ciprofloxacin/polycaprolactone‐collagen (GelMA‐CIP/PCL‐COL), designed to release EGF and TGFβ3 in a controlled manner. The GelMA‐CIP@PVA‐EGF/PCL‐COL@PVA‐TGFβ3 scaffold currently demonstrates sustained delivery of growth factors for 28 days, mechanical properties similar to ...

Weak decay constant of pseudscalar meson in a QCD-inspired model [PDF]

open access: yes, 2003
We show that a linear scaling between the weak decay constants of pseudoscalar and the vector mesons masses is supported by the available experimental data. The decay constant scale as $f_m/f_{pi}=M_V/M_{\rho}$ (f_m is decay constant and M_V vector meson

CURRENT ACCOUNT ADJUSTMENTS IN SELECTED TRANSITION COUNTRIES [PDF]

open access: yes, 2006
The paper investigates sharp reductions seen in current account deficits in selected transition countries in the 1992- 2003 period. The analysis focuses on three important aspects of these current account reversals: a) to examine those factors that might

Endoglin mediates the tumor‐ and metastasis‐promoting traits of stromal myofibroblasts in human breast carcinomas

open access: yesMolecular Oncology, Volume 19, Issue 9, Page 2557-2573, September 2025.
Carcinoma‐associated fibroblasts (CAFs) in tumors influence cancer progression. We identified endoglin (ENG) as a key factor in TGF‐β signaling in myofibroblastic CAFs (myCAFs), linked to poor breast cancer outcomes. Inhibiting ENG on myCAFs suppressed the TGF‐β‐Smad2/3 pathway, reducing primary tumor growth and metastasis.

Ultrathin (<10 nm) Electrochemical Random‐Access Memory that Overcomes the Tradeoff between Robust Weight Update and Speed in Neuromorphic Systems

open access: yesAdvanced Intelligent Systems, Volume 7, Issue 8, August 2025.
To address the tradeoff between synaptic linearity and operating speed, a Cu ion‐based ultrathin electrochemical random‐access memory is engineered using a 1.2 nm AlOx liner and 5 nm HfOx layer. The device exhibits fast and uniform weight updates under 50 μs pulses, along with long retention and high endurance, paving the way for robust synaptic units ...
