La conquista cristiana de Mallorca 1229 representa un paradigma importante en la isla. El crecimiento demográfico y económico estuvo determinado por llegada contingentes muy heterogéneos a las Baleares. Entre esos grupos se encontraban judíos que acudieron al lugar desde diferentes emplazamientos atraídos oportunidades protección real. Con el paso del tiempo, comunidades judías establecieron vi...

The goal of this paper is to study the effect of inexact first-order information on the first-order methods designed for smooth strongly convex optimization problems. It can be seen as a generalization to the strongly convex case of our previous paper [1]. We introduce the notion of (!,L,μ)-oracle, that can be seen as an extension of the (!,L)-oracle (previously introduced in [1]), taking into ...

Between the robust but slow (primal or dual) gradient methods and the fast but sensitive to errors fast gradient methods, our goal in this paper is to develop first-order methods for smooth convex problems with intermediate speed and intermediate sensitivity to errors. We develop a general family of first-order methods, the Intermediate Gradient Method (IGM), based on two sequences of coefficie...

The first clinical trial in malignant lynsphoma appeared in 1955.2 The authors found the drug to be definitely useful in follicular lymphoma and lymphocytic leukemia, and to some extent in Hodgkin’s disease. They concluded that it deserved further trial. This opinion was recently concurred in by a group of workers in this country3 who treated 24 patients. Our work with CB 1348 involved 31 patie...

Received ; accepted – 2 – ABSTRACT We have initiated a long-term project, the BOAO photometric survey of open clusters, to enlarge our understanding of galactic structure using UBV I CCD photometry of open clusters which have been little studied before. This is the second paper of the project in which we present the photometry of 12 open clusters. We have determined the cluster parameters by fi...
