A Solution for Exosome‐Based Analysis: Surface‐Enhanced Raman Spectroscopy and Artificial Intelligence

Advanced Intelligent Discovery, EarlyView.
Exosomes are emerging as powerful biomarkers for disease diagnosis and monitoring. This review highlights the integration of surface‐enhanced Raman spectroscopy with artificial intelligence to enhance molecular fingerprinting of exosomes. Machine learning and deep learning techniques improve spectral interpretation, enabling accurate classification of ...

Pair of Associated η-Ricci–Bourguignon Almost Solitons with Vertical Potential on Sasaki-like Almost Contact Complex Riemannian Manifolds

Mathematics
The manifolds studied are almost contact complex Riemannian manifolds, known also as almost contact B-metric manifolds. They are equipped with a pair of pseudo-Riemannian metrics that are mutually associated to each other using an almost contact ...

Diffusion Coefficient and Viscosity of Methyl Viologen Electrolyte Estimation Based on a Kinetic Monte Carlo Computational Approach Coupled with the Mean Square Displacement Method

Batteries &Supercaps, Volume 8, Issue 3, March 2025.
A novel and comprehensive 3D‐resolved kinetic Monte Carlo model coupled with mean square displacement analysis is introduced. This computational approach allows to explore, for the first time, the concentration and the state of charge effects on ionic diffusion coefficient and viscosity in methyl viologen‐based electrolytes used in organic redox flow ...

Cosmological Implications of a Non-Separable 5D Solution of the Vacuum Einstein Field Equations

, 2001
An exact class of solutions of the 5D vacuum Einstein field equations (EFEs) is obtained. The metric coefficients are found to be non-separable functions of time and the extra coordinate $l$ and the induced metric on $l$ = constant hypersurfaces has the ...

Promoting the Mathematization of Physics: Hermann Minkowski's Draft Presentations of His 1908 “Grundgleichungen” Paper

Berichte zur Wissenschaftsgeschichte, EarlyView.
I present and discuss two drafts of remarks prepared by the mathematician Hermann Minkowski (1864–1909). They were composed in December 1907 while preparing his paper on the “Basic Equations of Electromagnetic Processes in Moving Bodies” for publication in the Proceedings of the Göttingen Academy of Sciences.

Twistor construction of asymptotically hyperbolic Einstein--Weyl spaces

, 2013
Starting from a real analytic conformal Cartan connection on a real analytic surface $S$, we construct a complex surface $T$ containing a family of pairs of projective lines. Using the structure on $S$ we also construct a complex $3$-space $Z$, such that

Ultra‐High‐Efficiency On‐Chip CO2 Conversion by Nanosecond Self‐Pulsing Micro‐Plasma Devices

Carbon Energy, EarlyView.
A micro‐plasma chip with sub‐10‐μm electrode gaps is introduced for efficient CO2‐to‐CO conversion. The device self‐converts a DC power supply into nanosecond pulses, producing field‐emission electrons that vibrationally excite CO2, driving dissociation via the ladder‐climbing mechanism. A scaled‐up chip array achieves 30% single‐pass conversion and 50%

Finitary Topos for Locally Finite, Causal and Quantal Vacuum Einstein Gravity

, 2005
Previous work on applications of Abstract Differential Geometry (ADG) to discrete Lorentzian quantum gravity is brought to its categorical climax by organizing the curved finitary spacetime sheaves of quantum causal sets involved therein, on which a ...

Diffusion of Carbamazepine in Hydrophobic Zeolites: A Comparative Study Using Classical and Machine‐Learned Potentials

Chemistry – A European Journal, EarlyView.
Can hydrophobic, shape‐selective zeolites efficiently remove the persistent pharmaceutical CBZ from water? This work moves beyond the static picture of interaction energies by modeling diffusion with umbrella sampling and machine‐learned potentials. Even high intrinsic diffusion barriers can be overcome through exergonic adsorption from water, yielding

Emergent Gravity and Gauge Interactions from a Dynamical Temporal Field

Reports in Advances of Physical Sciences
In this paper, we introduce Chronon Field Theory (CFT) as a minimal and self-consistent framework in which conventional spacetime geometry and gauge interactions emerge from a single dynamical temporal field, eliminating the need for a fundamental ...
