SACRA D23 - Design of space time frequency polarization codes

[Approach to illness and death of Vadinienses in roman Hispania (I-IV centuries)].

The Vadinienses were a Cantabrian people who lived between the first and fourth centuries in the north of the Iberian Peninsula, northeast of the present province of León and the corresponding part of the current territory of Asturias. In this paper we study the possible causes of illness and death of the Vadinienses represented in their gravestones. The analysis of Vadinienses epitaphs shows t...

Global Sustainable Development priorities 500 y after Luther: Sola schola et sanitate.

Martin Luther succinctly summarized his theology in sola statements, such as sola scriptura, viewing the Bible (scriptura) as the only valid source of information about God rather than what he viewed as the extraneous, corrupting church doctrine of the time. As a secular side effect of this focus on individual reading skills, the Protestant territories were the first to acquire high literacy ra...

Sola schola et sanitate: human capital as the root cause and priority for international development?

This paper summarizes new scientific evidence supporting the hypothesis that among the many factors contributing to international development, the combination of education and health stands out as a root cause on which other dimensions of development depend. Much of this recent analysis is based on new reconstructions and projections of populations by age, sex and four levels of educational att...

SCHOLA GENEVENSIS MDLIX Quantum-Dot Cascade Laser: Proposal for an Ultra-Low-Threshold Semiconductor Laser

We propose a quantum-dot version of the quantum-well cascade laser of Faist et al. [Science 264, 553 (1994)]. The elimination of single phonon decays by the three-dimensional confinement implies a several-order-of-magnitude reduction in the threshold current. The requirements on dot size (10-20nm) and on dot density and uniformity [one coupled pair of dots per (180nm) with 5% nonuniformity] are...
