“…It is well known that the high T c cuprates are planar 2D materials. However it is also true that several of their properties carry a distinguished quasi-one-dimensional (1D) signature [2]. One recent evidence of that is the intertwining of the charge density wave and superconducting order which is also present in a 1D electron gas.…”

“…Using the so-called 'g-ology' notation [8] we have in this way = = ++ --( ) ( ) ( ) g k g k g k 4 and = +-( ) ( ) g k g k . 2 For spinless fermions the main effect of g 4 is to increment the Fermi velocity. Since g 4 plays no role in a BCS-type mechanism we may as well assume it to be of small magnitude and neglect its effect altogether.…”

“…Since g 4 plays no role in a BCS-type mechanism we may as well assume it to be of small magnitude and neglect its effect altogether. We can then, for simplicity, take = g g, 2 from now on. In this way, the Hamiltonian density  associated with equation (1) can be reduced to be of the form…”

In this work we investigate the effect produced by the BCS coupling in spinless fermions in one spatial dimension. Using bosonization techniques our initial model is rewritten in terms of a sine-Gordon field and a free massless scalar field. As a result the Cooper pair in our scenario is made up of soliton and antisoliton particles. We calculate the single particle Green's function, the pair correlation function and the optical conductivity associated with the physical fermions and we show how they differ from their conventional quasiparticle analogues. Finally, we compare our results with related experimental findings for high temperature superconductors and we display how they fit qualitatively well the related observed effects produced by the anti-nodal quasiparticles in those materials.

“…Acute episodes of bronchitis are a major cause of morbidity and a common precipitant of respiratory failure in patients with chronic obstructive pulmonary disease. The pathogenesis of acute bronchitis in these patients remains unclear but the balance of evidence supports a role played by colonizing bacteria, in particular, non-serotypable Haenmphiltis in/hwnzae (1)(2)(3)(4). In order for a bacterial pathogen to colonize the mucosal surface it must first overcome an array of specilic and non-specific defences.…”

Summary The ability of salivary secretions and sputum sol from patients with chronic bronchitis to inhibit the adhesion of non-serotypable Haemophilus influenzae to human buecal epithelial eells has been examined. Specific H. injluenzae antibodies were measured by an enzyme-linked immunosorbent assay (ELISA). Saliva and sputum levels of ami-//, influenzae immunoglobulin A (IgA) antibody were related inversely to buceal eell adherenee (r = -0 92). Absorption of saliva and sputum sol with //. injluenzae removed antibody detected by ELISA but only partially removed inhibition of attachment of bacteria. In patients with a history of recurrent bronchitis significantly more inhibitory aetivity remained after absorption of the secretory IgA (sIgA) specific antibody compared with patients who were resistant to acute episodes of infection (/'<0 05). These observations suggest that factors, other than sIgA. are present in respiratory seeretions and are capable of modulating //. /n//ufnrat'attaehment to buceal epithelial cells.

“…There are also other features, such as some figured capitals of Corinthian order (Martin-Bueno 1989: 188), that can also be dated to the late first quarter of the second century A.D. It seems likely that this style of capital did not appear in the region earlier, a conclusion supported by a close parallel from Caesarea Maritima (Fisher 1989: 113, 119, figs. 7-8).…”
