The diffraction dissociation process for the reaction yp -r’r-p is analyzed in detail. Much of the analysis is relevant to reactions initiated by hadrons. A procedure is suggested for adding nonresonant background (the V&ling term”) to p” production without double counting, and numeri\ cal calculations are presented. (Submitted to Phys. Rev.)

• How does a virus balance flexibility and stability of its major capsid protein? Parts double jelly roll structures trimeric Mavirus capsomers are highly dynamic. Flexible N-terminus wraps around neighboring protomers to prevent dissociation. Conformational switch prevents re-association assembly competent capsomers. Brace clasp mechanism confers allows for structural plasticity. Icosahedral v...

The mechanism of EcoRI endonuclease is substrate dependent. At 37 degrees dissociation of the enzyme-Form II DNA intermediates of ColE1 DNA and bacteriophage G4 RFI DNA is negligible. Therefore, both DNA strands with in the EcoRI sequence are cleaved during a single binding event. However, double strand cleavage of SV40 DNA occurs without dissociation of the enzyme in only 75% of the catalytic ...

We discuss photon-photon fusion mechanisms of dilepton production in proton-proton collisions with rapidity gap the main detector and one forward proton detectors. This is relevant for LHC measurements by ATLAS+AFP CMS+PPS. Transverse momenta intermediate photons are taken into account photon fluxes expressed terms electromagnetic form factors structure functions. Differential distributions $\x...

Theories about word production differ in whether they assume that lexical selection involves modality-specific representations or modality-neutral ones, called lemmas. The observation semantic errors aphasia may be restricted to either speaking writing has long been taken challenge lemma models (Hillis et al., Citation1999; Kemmerer, Citation2015, Citation2019). Whereas patients RGB, HW, and RR...
