In operando Structural Phase mapping of photosensitive neuristive devices under light excitation

Miguel Angel GARCIA-TUNON · Oscar RODRIGUEZ DE LA FUENTE · Alvaro MUNOZ NOVAL · Manuel ABUIN · y 2 más

Artificial neural networks (ANNs) are inspired by the biological neural networks of the human brain, aiming to replicate its ability to learn, adapt, and process information in a parallel and flexible manner. The study of VO2 is particularly interesting for the development of ANNs due to its unique physical properties....

Operando determination of the kinetics and structure of the copper-sites in copper-exchanged offretite using copper K-edge XANES spectroscop

Dragos Constantin STOIAN · Przemyslaw RZEPKA · Kenneth MARSHALL · Johannes WIESER · y 2 más

The methane-to-methanol conversion is seen as one of the "holy grail" reactions of catalysis. One extensively examined approach is the chemical looping approach using copper exchanged zeolites. In-house studies have determined that copper-exchanged zeolite offretite outperforms all other zeolites in multiple metrics, n...

Dot product graphs in finite fields

Chengfei Xie · Gennian Ge

In this paper, we study the dot-product graphs in $\mathbb{F}_q^d$. We prove that if the size of the product of two adjacent sets is large enough, then the set of dot-product graphs has positive density. Our method is based on finite field Fourier analytic techniques.
