Identification and Unusual Properties of the Master Regulator FNR in the Extreme Acidophile Acidithiobacillus ferrooxidans

The ability to conserve energy in the presence or absence of oxygen provides a metabolic versatility that confers an advantage in natural ecosystems.The switch between alternative electron transport systems is controlled by the fumarate nitrate reduction transcription factor (FNR) that senses oxygen via an oxygen-sensitive [4Fe-4S]2+ iron-sulfur cl

Autogenous tooth fragment reattachment: A multidisciplinary management for complicated crown-root fracture with biologic width violation

Fractures of multiple permanent anterior teeth can be a traumatic experience for children, with functional, esthetic and psychological aspects.The treatment of complicated crown-root fractures (CRFs) is more challenging when the biologic width is Lunchbox Seals violated.This paper presents a case of 12-year boy with complicated CRF of teeth #12 and

Ambitwistor strings and reggeon amplitudes in N=4 SYM

We consider the description of reggeon amplitudes (Wilson lines form factors) in Cases N=4 SYM within the framework of four dimensional ambitwistor string theory.The latter is used to derive scattering equations representation for reggeon amplitudes with multiple reggeized gluons present.It is shown, that corresponding tree-level string correlation
