Hard Machining of Inconel 690 Using Minimum Quantity Nanoparticle‐Enriched Vegetable Oils: A Sustainable Approach

Engineering Reports, Volume 7, Issue 10, October 2025.
This study explores alumina and silica nanoparticle‐enriched soybean oil for sustainable machining of Inconel 690. Alumina‐based nanofluid reduced surface roughness, force, temperature, and tool wear significantly. RSM‐GA optimization validated with 3.04% error highlights its eco‐efficiency, tool life enhancement, and potential for greener ...

Parameter identifiability in a class of random graph mixture models [PDF]

, 2010
We prove identifiability of parameters for a broad class of random graph mixture models. These models are characterized by a partition of the set of graph nodes into latent (unobservable) groups.

Preparation of Zwitterionic Silica‐Based Sorbents for Simultaneous Extraction of Acidic and Basic Pharmaceuticals From Water Samples

Journal of Separation Science, Volume 48, Issue 9, September 2025.
ABSTRACT The sol‐gel approach was applied to develop three homemade silica sorbents. These sorbents where functionalized with mixed‐mode zwitterionic exchange groups using only one additive to introduce at once the strong cation‐ (sulfonic groups) and strong anion‐exchange (quaternary amines) moieties. The developed materials were applied for the solid‐

Update on Opium Alkaloids in Food: Exploring Their Occurrence, Effect of Culinary Processing and Advances in Analytical Methodologies

Comprehensive Reviews in Food Science and Food Safety, Volume 24, Issue 5, September 2025.
ABSTRACT Following the implementation of the new European legislation on opium alkaloids (OAs) in food in 2023, scientific research has focused on developing analytical methodologies to determine the presence of these compounds in different foods. However, health authorities continue to suggest further studies to evaluate the occurrence of main OAs and

Optical conductivity of a strong-coupling polaron

, 2013
The polaron optical conductivity is derived within the strong-coupling expansion, which is asymptotically exact in the strong-coupling limit. The polaron optical conductivity band is provided by the multiphonon optical transitions.

Reinforcement learning–based task allocation and path‐finding in multi‐robot systems under environment uncertainty

Computer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 22, Page 3408-3429, 9 September 2025.
Abstract Autonomous robots have the potential to significantly improve the operational efficiency of multi‐robot systems (MRSs) under environment uncertainties. Achieving robust performance in these settings requires effective task allocation and adaptive path‐finding.

"Weakly" Elliptic Gorenstein Singularities of Surfaces

, 1998
The main message of the paper is that for Gorenstein singularities, whose (real) link is rational homology sphere, the Artin--Laufer program can be continued. Here we give the complete answer in the case of elliptic singularities.
