Deciphering Precambrian Litho-structural settings and barite-associated mineralization through integrated hyperspectral and geophysical datasets

Effective lithological mapping and mineral exploration remain challenging in geologically complex and underexplored Precambrian terrains. This is particularly relevant to the Arabian–Nubian Shield (ANS), a Neoproterozoic orogenic belt extending across northeastern Africa and Arab...

Bio-inspired flexible pressure sensors: morphology-guided structure–function relationships, reliability, and future perspectives

Bio-inspired flexible pressure sensors have emerged as a major class of soft sensing systems for wearable electronics, electronic skin, human–machine interfaces, and soft robotics because biological structures provide effective design principles for regulating deformation, contac...

A New Analysis of the Mechanics of Fixed-Plug Tube Drawing with Application on a Low Carbon Steel Tube

Knowledge of the deformations that occur during the plastic forming of metals and the necessary forces is of key importance in engineering. The Fixed-Plug Tube Drawing (FPTD) process permits reductions of the diameter and the wall thickness of a tube to the desired geometry. In t...

Integrating geophysical and underwater robotic surveys with transport and geochemical modeling to assess the Solotvyno salt mine hazard in the Transcarpathia province of Ukraine

Abstract The Solotvyno salt mine in West Ukraine presents significant environmental and infrastructural risks due to uncontrolled salt dissolution following mine flooding, causing ground subsidence, sinkhole formation, and transboundary contamination of the Tisza River. This stud...

GPU-Parallelization of the Numerical Solution of Large-Scale Transient Partial Differential Equations

Efficient and scalable numerical methods for time-dependent partial differential equations are of central importance. This study extends our previous examinations of OpenCL-based parallel implementation of three explicit finite difference schemes: the one-stage Constant Neighbor...

Generalized quasiorders: constructions and characterizations

Abstract Quasiorders $$ \varrho \subseteq A^{2}$$ ϱ ⊆ A 2 have the property that an operation $$f:A^{n}\rightarrow A$$ f : A n → A preserves $$\varrho $$ ϱ if and only if each (unary) translation obtained from f is an endomorphism of $$\varrho $$ ϱ . Generalized quasiorders $$\va...

Application of magnetically separable silica aerogel-supported palladium catalyst in the hydrogenation of aromatic nitro compounds

Abstract Palladium nanocatalyst has been prepared via sonication-induced reductive deposition for the hydrogenation of nitro groups, tested in the two industrially most significant nitro compound hydrogenation processes: nitrobenzene hydrogenation to aniline and 2,4-dinitrotoluen...

Bayesian framework for process-aware tool wear predictive modeling of 1.4301 steel

Abstract Tool wear is inherent in material removal processes. It results in increased production costs, poor surface finish, and reduced dimensional accuracy of the workpieces, particularly when machining difficult-to-cut materials. Currently, industries rely on manual tool inspe...
