Derivations of UP-algebras by means of UP-endomorphisms

The notion of $f$-derivations of UP-algebras is introduced, some useful examples are discussed, and related properties are investigated. Moreover, we show that the fixed set and the kernel of $f$-derivations are UP-subalgebras of UP-algebras,and also give examples to show that the two sets are not UP-ideals of UP-algebras in general.

Catching Up with Flu

The sniffles, sneezes, aches, and pains of flu are a dreaded part of the winter season. The fear of another deadly pandemic is ever imminent, and this issue’s Select looks at recent efforts to understand this ever-shifting virus. From efforts aiming to predict its geographical spread to those that elucidate the basic viral biology and host response, researchers are looking for new ways to stay ...
