Local magnetization in thes-d model
Il Nuovo Cimento B Series 10, 1969A calculation of the local magnetization in thes-d model is made up to terms of second order in «J ». It is shown that, assuming a constant density of states symmetric about the Fermi level, one obtains a singular contribution to the local magnetization in the limit of small magnetic fields whose value is\(\left\langle {S^z } \right\rangle _{\sin g ...

Eigenphases of theS-matrix at high energy
Il Nuovo Cimento A, 1973In the spirit of a statistical approach to theS-matrix, we discuss the concept of resonant state and we are led to generalize the eigenphase formalism to many-particle processes. We show that the object to be considered is the connected part of theS-matrix at fixed total four-momentum and we give strong arguments in favour of the conjecture that this ...

On time delay in theS-wave scattering
Lettere Al Nuovo Cimento Series 2, 1985We have found that the time delay of theS-wave zero-energy resonance scattering must be expressed as the sum of the ordinary term 2(dδ0/de) and the now term 2/Г. WhereГ denotes the half-width of wave packet, and dδ0/de does the derivative of theS-wave phase shift with respect to energy.

“Saying thes woordes or the lyke”
2020This chapter examines the forms and functions of speech representation in Early Modern English correspondence using corpus-based methods. It considers how the sociopragmatic properties of speech representation are shaped by the communicative context of letter-writing, and identifies key similarities and differences with speech representation in other ...

On a construction of theS-matrix in QED
Il Nuovo Cimento A, 1983The construction proceeds in three steps: At first the electron-positron field is quantized in a fixedC-number potentialA (external-field problem). The correspondingS-operator is uniquely determined up to a phase depending onA. The second step is the construction of this phase by using causality.

On theS-Invariance Property forS-Flows
2010Definimos una relación de equivalencia en un espacio topológico que es actuado por el monoide topológico Scomo un semigrupo de transformación. A continuación, damos algunos resultados sobre las clases S-invariante para esta relación. También proporcionamos una condición para la existencia de clases S-invariantes relativas.

The Missing Mythology: Bar thes in Québec
Canadian Journal of Film Studies, 1997Cet article, qui introduit la traduction ci-dessous, examine le travail de collaboration de Roland Barthes et Hubert Aquin sur le film Le Sport et les hommes. En plus de combler une lacune dans l’histore du documentaire à l’ONF/NFB, l’auteur (qui a traduit le texte de Barthes) offre une nouvelle lecture de l’intérêt particulier que Barthes voue au ...

Genetica, 1969
Interspecific crosses among 27 species ofNicotiana, including all six S.I. species of the genus, revealed a complex, but highly systematic pattern of unilateral incompatibility, apparently encompassing the whole genus. There was a definite relationship between the type of incompatibility and the site of inhibition: in interspecific incompatibility the ...

Experimental testing of the analyticity structure of theS-matrix
Il Nuovo Cimento A, 1967A tentative experimental test of the analyticity structure of theS-matrix in low-energy nucleon-nucleon scattering is performed by showing that among an appreciable number of functions describing the energy dependence of phase shifts in proton-proton scattering dynamics, satisfying various threshold and asymptotic requirements, those having ...

Thermally enhanced α-decay and thes-process
Astrophysics and Space Science, 1971In this paper temperature enhanced α-decay at high stellar temperatures is investigated in conjunction withs-process nucleosynthesis. The temperature dependence of α-decay is the result of more energetic, hence faster, decay from thermally excited nuclear states.
