Conform [1], [2] numim multi-processors sistemele cu mai mult de un processor, în timp ce termenul de many-processors este folosit pentru sistemele cu un număr foarte mare de procesoare. Fundamentarea teoretică pentru cele două tipuri de maşini este diferită şi semnificativă pentru înţelegerea evoluţiei ştiinţei calculului în era paralelismului emergent. În timp ce multi-processor-ul este o con...

An important objective of contemporary synthesis endeavors is the development of new transformations that rapidly evolve molecular complexity in a stereocontrolled fashion. One approach toward this goal is to combine two or more distinct reactions into a single transformation, producing a process often referred to as a sequential, tandem, cascade, or domino reaction. In this Perspective, we dis...

The main objective of this Project is to develop and promote basic research in the framework of Incidence Geometries, Galois Geometries and Combinatorics, both through active investigation performed by the involved researchers on subjects of great up-to-date scientific interest and through the organisation of national and international Conferences, Workshops and specialised Schools. Further, sp...

We consider the bosonic and fermionic symmetries of five-dimensional Maxwelland YangMills-Einstein supergravity theories on a spacetime with boundaries (isomorphic to M × S/Z2). Due to the appearance of the “Chern-Simons” term, the classical action is not generally invariant under gauge and supersymmetries. Once bulk vector fields are allowed to propagate on the boundaries, there is an “inflow”...

In lucrare este prezentată o nouă variantă a metodei spectrale de rezolvare a ecuaţiilor diferenţiale cu condiţii la limită, aplicabilă la calcule ab-initio pentru tunelarea electronilor. Prin exprimarea potenţialului total în care se mişcă electronul ca o dezvoltare în serie după un anumit set de funcţii într-un spaţiu Hilbert, ecuatiile obtinute prin metoda colocatiei pot admite o integrare a...

Sir, We thank Tom Kindlon for his letter, in which he raises several important issues. We will respond to all the issues in the same order as they appear in his letter. First, Tom Kindlon points out that cognitive behavioural therapy (CBT) is not a panacea for the chronic fatigue syndrome (CFS). It should be obvious from all previous meta-analyses that CBT does not lead to a full recovery in al...

In this report, centered on the activities within the MURST-PRIN project “Fisica teorica del nucleo e dei sistemi a più corpi” we discuss recent advances on the following items: i)neutrinos as probes of the solar interior and of other astrophysical objects; ii)neutrinos as probes of physics beyond the Standard Model of electroweak interactions; iii)the role of nuclear physics in i) and ii); iv)...

One says that a variety X over Q violates the Hasse prin iple if X(Q v ) 6= ; for all ompletions Q v of Q (i.e., R and Q p for all primes p) but X(Q) = ;. Hasse proved that degree 2 hypersurfa es in P n satisfy the Hasse prin iple. In parti ular, if X is a genus 0 urve, then X satis es the Hasse prin iple, sin e the anti anoni al embedding of X is a oni in P 2 . Around 1940, Lind [Lin℄ and (ind...
