We present a new calculation of axionlike particle (ALP) production in the semiexclusive photon-initiated (PI) channel, that is either with intact outgoing protons or rapidity gaps final state, and no color flow between colliding LHC protons. This first full treatment this process, accounting for both possibility proton dissociation survival factor probability additional proton-proton interacti...

The $^{16}$F nucleus is situated at the proton drip-line and unbound by emission only about 500 keV. Continuum coupling then prominent in this nucleus. Added to that, its low-lying spectrum consists of narrow resonances as well. It a very good candidate study nuclear structure reactions drip-line. scattering proton-proton cross section have been calculated with coupled-channel Gamow shell model...

Proton pumping in thylakoid membranes and backflow of protons through the active ATP synthase CF0-CF1 (where CF0 is the proton channel and CF1 is the catalytic portion) were investigated by flash spectrophotometry. A steady pH difference across the membrane was generated by continuous measuring light, supplemented by voltage transients that were generated by flashing light. In the presence of P...

In living cells, molecular motors convert chemical energy into mechanical work. Its thermodynamic energy efficiency, i.e. the ratio of output mechanical work to input chemical energy, is usually high. However, using two-state models, we found the motion of molecular motors is loosely coupled to the chemical cycle. Only part of the input energy can be converted into mechanical work. Others is di...

A number of uncouplers and energy transfer inhibitors suppress photosystem II cyclic photophosphorylation catalyzed by either a proton/electron or electron donor. Valinomycin and 2,4-dinitrophenol also inhibit photosystem II cyclic photophosphorylation, but these compounds appear to act as electron transport inhibitors rather than as uncouplers. Only when valinomycin, KCl, and 2,4-dinitrophenol...

Recent measurements from the HERMES and SMC collaborations show a remarkably large azimuthal single-spin asymmetries AUL and AUT of the proton in semi-inclusive pion leptoproduction γ∗(q)p → πX. We show that final-state interactions from gluon exchange between the outgoing quark and the target spectator system lead to single-spin asymmetries in deep inelastic lepton-proton scattering at leading...

Proton exchange membranes (PEM) for a direct methanol fuel cell (DMFC) have main drawbacks which are methanol permeability, reduced proton conductivity and the cost of the membrane. This paper reviews different polymeric materials such as fluorinated, non-fluorinated, acid-base complex, and composite membranes for DMFC. Currently, nonfluorinated membranes gain a lot of atte...

group. The spectra, as shown in Figure 2 , can be semiquantitatively reproduced using the LAOCOON computer program with reduced values for the carbon-proton coupling constant^.^ These calculations are approximate because they do not include the asymmetry introduced by the decoupling field or any relaxation effects. We have performed additional experiments which show that it is not necessary for...

We study the Odderon contribution to elastic pp and pp̄ scattering at high energies. Different models for the Odderon–proton coupling are considered and their effects on the differential cross section in the dip region are investigated. We use a Regge fit by Donnachie and Landshoff as a framework and replace its Odderon contribution by the different models. We consider two models for the Odderon...
