E- and F-region coupling between an intense sporadic E layer and a mesoscale traveling ionospheric disturbance [PDF]
Considerable controversy exists concerning the relative roles of the E- and F-regions in controlling irregularity formation in the mid-latitude ionosphere, largely because electric fields due to a plasma instability in one region may map to the other ...

Fe-Promoted C-F Activation of Aryl Fluorides Enables Heck-Type Coupling with Alkenes and One-Pot Synthesis of Indenes [PDF]
Metal-mediated aryl fluoride activation presents challenges because of the thermodynamically robust C-F bond but also provides opportunities to develop C-C coupling reactions with this unconventional electrophile.

A new physics scenario shows that four-fermion operators of Nambu-Jona-Lasinio (NJL) type have a strong-coupling UV fixed point, where composite fermions F (bosons $$\Pi $$ Π ) form as bound states of three (two) SM elementary fermions and they couple to

E 6 Yukawa couplings in F-theory as D-brane instanton effects
At weak coupling the neighborhood of a E 6 Yukawa point in SU(5) GUT F-theory models is described by a non-resolvable orientifold of the conifold. We explicitly show, first directly in IIB and then via a mirror symmetry argument, that in this limit the E

Light mediators in anomaly free U (1) X models. Part II. Constraints on dark gauge bosons
We consider experimental constraints in the MeV region in order to determine the parameter space for the U(1) X extension of the Standard Model, presented in the first part of our work. In particular, we focus on the model UV-completed by cold WIMPs.

Traces of electron-phonon coupling in one-dimensional cuprates
The appearance of certain spectral features in one-dimensional (1D) cuprate materials has been attributed to a strong, extended attractive coupling between electrons.

Gauge coupling unification in E 6 F-theory GUTs with matter and bulk exotics from flux breaking
We consider gauge coupling unification in E 6 F-Theory Grand Unified Theories (GUTs) where E 6 is broken to the Standard Model (SM) gauge group using fluxes. In such models there are two types of exotics that can affect gauge coupling unification, namely
