One central goal in molecular evolution is to pinpoint the mechanisms and evolutionary forces that cause an enzyme to change its substrate specificity; however, these processes remain largely unexplored. Using the glycolytic ...

Mining activities have been carried out for thousands of years and nowadays have an enormous worldwide use to obtain important metals of industrial use. These include copper, iron, gold and several others. Although modern ...

We prove that, under some conditions, a linear nonautonomous difference system is Bylovs almost reducible to a diagonal one whose terms are contained in the Sacker and Sell spectrum of the original system. In the above ...

The renewable energy sector is growing at a rapid pace in northern Chile and the solar energy potential is one of the best worldwide. Therefore, many types of solar power plant facilities are being built to take advantage ...

Conceptual DFT and quantum chemical topology provide two different approaches based on the electron density to grasp chemical concepts. We present a model merging both approaches, in order to obtain physical properties ...

The study of species in their native geographic ranges is key to understanding how human activity has influenced spatial fragmentation or species homogenization. The Argentinian silverside Odontesthes bonariensis, of ...

Mitochondrial dysfunction and oxidative damage, often accompanied by elevated intracellular iron levels, are pathophysiological features in a number of neurodegenerative processes. The question arises as to whether ...

Background: CLCA is a family of metalloproteases that regulate Ca2+-activated Cl- fluxes in epithelial tissues. In HEK293 cells, CLCA1 promotes membrane expression of an endogenous Anoctamin 1 (ANO1, also termed ...

Exact electromagnetic wave solutions to Maxwell equations on anisotropic Bianchi I cosmological spacetime backgrounds are studied. The waves evolving on Bianchi I spacetimes exhibit birefringence (associated with linear ...
