Nuclear Physics B, 1967 Abstract We calculate proton-proton Bremsstrahlung cross sections using the Tabakin separable potentials to generate off-shell nucleon-nucleon t-matrix elements in low partial waves and off-shell one-pion-exchange amplitudes for the higher partial waves.

Water, Protons, and the Gating of Voltage-Gated Potassium Channels
MembranesIon channels are ubiquitous throughout all forms of life. Potassium channels are even found in viruses. Every cell must communicate with its surroundings, so all cells have them, and excitable cells, in particular, especially nerve cells, depend on the ...

FEBS Letters, EarlyView.In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties
FEBS Letters, EarlyView.A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

The leading proton effect in proton-proton collisions
Nuclear Physics B, 1973 Abstract The p spectrum data in the range s = 28 to s = 1995 are described with the triple Regge formula. The behaviour of the various couplings at small | t | is explored. It is found that the non-scaling terms, at s ≅ 400 GeV 2 remove the turnover expected if the triple pomeron vanishes at t = 0.

FEBS Letters, EarlyView.The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

On proton-proton bremsstrahlung [PDF]
Physics Letters B, 1967 Abstract The cross section for proton-proton bremsstrahlung has been calculated for soft photons in a model independent way. Comparison with experiments has been made.
