On the additive image of zeroth persistent homology
Abstract For a category X$X$ and a finite field F$F$, we study the additive image of the functor H0(−;F)∗:rep(X,Top)→rep(X,VectF)$\operatorname{H}_0(-;F)_* \colon \operatorname{rep}(X, \mathbf {Top}) \rightarrow \operatorname{rep}(X, \mathbf {Vect}_F)$, or equivalently, of the free functor rep(X,Set)→rep(X,VectF)$\operatorname{rep}(X, \mathbf {Set ...

Explainable AI reveals how biological feedstock quality, energy markets, and policy factors jointly shape ethanol price dynamics. Deep learning improves forecasting accuracy while identifying sugarcane quality (TRS), gasoline prices, taxation, and macroeconomic variables as key drivers in a major bioenergy system.

The RE4Al13Pt9 series has been extended to RE = Y, La‐Nd, Sm, Gd‐Dy. The compounds have been investigated by X‐ray diffraction and magnetic susceptibility measurements. Of the RE4Al13Pt9 series, the RE = Ce, Pr, and Eu representatives were previously reported. In this work we extend the series to RE = Y, La‐Nd, Sm, Gd‐Dy.

Katalytischer Schwefelatomtransfer vermittelt durch einen Bis(disulfido)‐Titankomplex
Mehrelektronentransformationen mit Titan sind aufgrund der limitierten Zugänglichkeit niedervalenter Vorstufen bislang nur unzureichend untersucht. Die Vier‐Elektronen‐Aktivierung von elementarem Schwefel durch einen Ti(IV)‐Komplex führt zu einem seltenen Bis(disulfido)‐Titankomplex, der die effiziente katalytische Synthese von Isothiocyanaten aus ...

Catalytic Sulfur‐Atom Transfer Enabled by a Bis(disulfide) Titanium Complex
Multi‐electron transformations with titanium are underexplored due to limited access to low‐valent precursors. The four‐electron activation of elemental sulfur by a Ti(IV) complex yields a rare titanium bis(disulfide) complex, enabling the efficient catalytic synthesis of isothiocyanates from isonitriles under mild conditions.
