The Consumption of Reference Resources

Under the operational restriction of the U(1)-superselection rule, states that contain coherences between eigenstates of particle number constitute a resource. Such resources can be used to facilitate operations upon systems that otherwise cannot be performed. However, the process of doing this consumes reference resources. We show this explicitly for an example of a unitary operation that is f...

Chemistry Research in Catalonia: 1996-2002 * Human Resources

Organization of research personnel We should highlight here the efforts that have been made by the Catalan administration to coordinate research. The structure, size, objectives and affiliation of consolidated research groups (CRGs) have not changed significantly since the previous six-year period (see Table 2). Nor has specific financing changed, continuing to be quite modest. These groups hav...

A Machine Learning Approach to No-Reference Objective Video Quality Assessment for High Definition Resources

The video quality assessment must be adapted to the human visual system, which is why researchers have performed subjective viewing experiments in order to obtain the conditions of encoding of video systems to provide the best quality to the user. The objective of this study is to assess the video quality using image features extraction without using reference video. RMSE values and processing ...

Allium Genetic Resources with Particular Reference to Onion

As in many other crop species, also in Allium crops genetic erosion is taking place. In this mini review the current global state of the art is presented on Allium ex situ genetic resources and more in particular on onion genetic resources. Furthermore future possible actions are indicated to preserve the Allium genepool in a more effective way, amongst which a proposal to develop an Allium gen...
