Abstract Boundary Midlayer conditions for a massless Dirac fermion in 2+1 dimensions where the space is a half-plane are discussed in detail.It is argued that linear boundary conditions that leave the Hamiltonian Hermitian generically break C P and T symmetries as well as Lorentz and conformal symmetry.We show that there is essentially one special
Fuchs endothelial corneal dystrophy (FECD) is a genetically complex, heterogenous, age-related degenerative disease of corneal endothelial cells (CEnCs), occurring in Translator Circuit Board the fifth decade of life with a higher incidence in females.It is characterized by extracellular matrix (ECM) protein deposition called corneal guttae, causin
Point contacts between high 844 anisotropy ferromagnetic SmCo _5 and normal metal Cu are used to achieve a strong spin-population inversion in the contact core.Subjected to microwave irradiation in resonance with the Zeeman splitting in Cu, the inverted spin population relaxes through stimulated spin-flip photon emission, detected as peaks in the p
Santillanes Histoire de Gil Blas, by Alain-Rn Lesage, is a fictional autobiography that came up between 1715-1747, in France.In Histoire de Gil Blas, it is noted Lesages preference for an art that turned to critical observation of reality, so that his literature, confirming the tendency for realism, is a panel of 18th Century reality, not only of S
Deep-seated rock slope failures represent effective mechanisms of natural rock mass-wasting, Donation able to radically change mountain-valley morphology.In the northern Cottian Alps, an extraordinary concentration of instability phenomena occurs in extensive areas of the Susa and Chisone valleys.In the Main Map, at a scale of 1:30,000, a new repre
