An Unsupervised Learning Approach for Coal Spontaneous Combustion Warning Level Classification Using t-SNE and k-Means Clustering

Applied Sciences
Accurate prediction of coal spontaneous combustion levels is crucial for preventing and controlling spontaneous combustion in goaf areas. To address the ambiguity in classification standards of coal spontaneous combustion warning levels, 21 groups of ...

Combustion in thermonuclear supernova explosions

, 2017
Type Ia supernovae are associated with thermonuclear explosions of white dwarf stars. Combustion processes convert material in nuclear reactions and release the energy required to explode the stars.

Thermodynamic Insights Into Direct Methane to Methanol Conversion Using O2 and CO2 Oxidants

ChemistryOpen, Volume 15, Issue 5, May 2026.
A thermodynamic analysis compares O2 and CO2 for the direct partial oxidation of methane to methanol. While O2 offers higher theoretical conversions, it poses safety risks and favors total oxidation. CO2 presents a safer, more sustainable alternative despite its thermodynamic limitations.

The Philosopher and The Dancer [PDF]

, 2015
The Philosopher and The Dancer is an act of spontaneous, solo, movement improvisation; offered here as one particularized instantiation and re-enactment of the corporeal situatedness and interrelatedness of self and world that characterizes Merleau-Ponty’

Discovery and Evaluation of Cadmium‐Adapted Daphnia pulex Genotypes in a Region of Historical Mining Reveals Adaptation Protects the Germline From Cadmium‐Induced Mutations

Molecular Ecology, Volume 35, Issue 9, May 2026.
ABSTRACT Exposure to chemical pollutants can alter the rate and genome‐wide distribution of germline mutations. However, studies measuring the effects of chemical exposure on mutation rates and spectra have not considered the ecological and evolutionary backgrounds of the studied genotypes, which could influence the rates and patterns of germline ...

The Relationship Between Catalyst and Solvent in Hydrogenation via Condensed Phase Heterogeneous Catalysis

ChemSusChem, Volume 19, Issue 8, 28 April 2026.
Heterogeneous catalysis has historically been developed in the gas phase, however, we have found it pertinent to highlight solvent effects that must be accounted for in liquid environments. Condensed phase catalysis, like that in biomass, petroleum and the conversion of CO2, stands to benefit from the typically overlooked discussion regarding the ...
