Restrictions on the coherence of the ultrafast optical emission from an electron-hole pairs condensate

We report on the transfer of coherence from a quantum-well electron-hole condensate to the light it emits. As a function of density, the coherence of the electron-hole pair system evolves from being full for the low density Bose-Einstein condensate to a chaotic behavior for a high density BCS-like state. This degree of coherence is transfered to the light emitted in a damped oscillatory way in the ultrafast regime. Additionally, the photon field exhibits squeezing properties during the transfer time. We analyze the effect of light frequency and separation between electron and hole layers on the optical coherence. Our results suggest new type of ultrafast experiments for detecting electron-hole pair condensation.Comment: 4 pages,3 figures, to be published in Physical Review Letters. Minor change

Energy resolution of terahertz single-photon-sensitive bolometric detectors

We report measurements of the energy resolution of ultra-sensitive superconducting bolometric detectors. The device is a superconducting titanium nanobridge with niobium contacts. A fast microwave pulse is used to simulate a single higher-frequency photon, where the absorbed energy of the pulse is equal to the photon energy. This technique allows precise calibration of the input coupling and avoids problems with unwanted background photons. Present devices have an intrinsic full-width at half-maximum energy resolution of approximately 23 terahertz, near the predicted value due to intrinsic thermal fluctuation noise.Comment: 11 pages (double-spaced), 5 figures; minor revision

New e-health services for the European Network for Rare and Congenital Anaemias (e-ENERCA)

Rare Anaemias (RA) are a group of Rare Diseases (RD) with prevalence, in Europe, less than 5 per 10.000 individuals. Major forms of RAs require red blood cell transfusions, iron chelation, splenectomy, and/or in very severe cases, bone marrow transplantation, as main therapeutic options. Beta-thalassaemia major is predominant in Italy and Cyprus, and sickle cell disease (SCD) in African population. During the last 30 years, SCD is increasing in Europe due to African immigration, leading to an important impact on health care burden in several countries. Preventive programs, aiming to epidemiological control, and improvement of diagnosis and clinical management of major RA, are crucial for decreasing the affected birth rate and achieving an efficient balance between morbidity and patient’s life expectancy. Since 2003, the European Network for Rare and Congenital Anaemias (ENERCA) has taken an active role for improving this situation by the following actions: a) the identification of Centres of Expertise on RAs in Europe according to the recommendations of ENERCA White Book b) the promotion of best clinical and laboratory practices by the publication of ENERCA recommendations c) the improving of continuous medical education, by organising topic-specific training courses, workshops and symposia, e) the empowerment of patients, by cooperation with Patient’s Associations, and co-organizing a bi-annual European Symposium on RAs with interactive patients-health professionals sessions. In September 2013, a new phase of the project called e-ENERCA has started with the aim to provide, patients and professionals with e-Health tools for assure the same access to health services in RAs across Europe, independently from the country of practise and origin of the patients. e-Health services will be developed through the set-up of three different e-platforms endorsed by ENERCA website (http://www.enerca.org) : 1) e-Registry, a Pan European registry of RAs for gathering patient’s data necessary to achieve the required sample size for epidemiological surveillance and clinical research 2) e-Learning , a teaching platform for the dissemination of knowledge, continuous medical education, and best practices awareness and promotion through Internet, and 3) e-Medicine , a platform to provide, at distance, expertise (telexpertise) and diagnostic facilities (telediagnosis), avoiding, when possible, the need of travelling. Finally, e-ENERCA will also promote the recognition of the previously identified Centres of Expertise in RAs (White Book) by the national health authorities, a mandatory condition for ENERCA final recognition as European Reference Network in Rare Anaemias (RA-ERN)

Mechanisms for longitudinal transport on early life stages in benthic-pelagic fishes within a tide-dominated estuary

Mechanisms that control the longitudinal transport of larvae and juveniles in nursery grounds such as estuaries are reported for some species. However, the behaviour and population consequences of these mechanisms are still uncertain. In this study, we tested selective tidal-stream transport from the along-channel (up-and down-stream) and cross-channel (from one margin to the other) perspectives for two kinds of fish: estuarine-resident gobies (Pomatoschistus spp.) and marine estuarine-opportunistic anchovies (Engraulis encrasicolus). Three cruises were conducted in the lower Guadalquivir estuary, on the ebb and on the flood of spring tides in summer. Plankton samples were collected across a channel section, at three stations (one in the middle of the channel and two in adjacent shallower areas), near the surface and near the bottom simultaneously. In addition, multiple physico-chemical variables (temperature, turbidity, dissolved oxygen, pH, salinity, chlorophyll-a, along with wind and current direction and velocity) were measured to examine the different correlations used by the studied fish in their strategies. The benthic distribution of gobies indicated that they used flood currents near the bottom of lateral (shallow) areas to ingress into and remain in the estuary, temperature and/or dissolved oxygen being their main possible cues. On the contrary, the anchovies were more abundant near the surface, especially on the ebb tide, showing downstream advection, which was mainly influenced by salinity. However, the largest indi-vidual anchovies in the lateral/shallow zones suggested a behavioural ontogeny, which, together with wind induced transport, could contribute to their retention. This comparison also enhanced the knowledge of the habitat distribution of two species common and abundant in estuaries, anchovies and gobies.info:eu-repo/semantics/publishedVersio

Presentation of histoplasmosis as mononucleosis syndrome in an immunocompetent patient

Q3Artículo original61-63Histoplasmosis is a fungal disease usually occurring in endemic areas that can affect immuno-impaired patients in whom pulmonary involvement is the rule. We present the case of an 18 year-old immunocompetent, male patient, resident of the State of Florida, who showed signs of mononucleosis syndrome that included odynophagia, cervical adenomegaly, sporadic fever and rash; however, no pulmonary involvement or visceromegaly were present. Faced with this atypical and unexpected clinical picture, histoplasmosis infection was eventually diagnosed following cervical lymph-node biopsy. Disseminated histoplasmosis may have unexpected manifestations, as is pointed out in the case described below

Quantum transport in quantum networks and photosynthetic complexes at the steady state

Recently, several works have analysed the efficiency of photosynthetic complexes in a transient scenario and how that efficiency is affected by environmental noise. Here, following a quantum master equation approach, we study the energy and excitation transport in fully connected networks both in general and in the particular case of the Fenna-Matthew-Olson complex. The analysis is carried out for the steady state of the system where the excitation energy is constantly "flowing" through the system. Steady state transport scenarios are particularly relevant if the evolution of the quantum system is not conditioned on the arrival of individual excitations. By adding dephasing to the system, we analyse the possibility of noise-enhancement of the quantum transport.Comment: 10 pages, single column, 6 figures. Accepted for publication in Plos On

Non-Markovian stochastic description of quantum transport in photosynthetic systems

We analyze several aspects of the transport dynamics in the LH1-RC core of purple bacteria, which consists basically in a ring of antenna molecules that transport the energy into a target molecule, the reaction center, placed in the center of the ring. We show that the periodicity of the system plays an important role to explain the relevance of the initial state in the transport efficiency. This picture is modified, and the transport enhanced for any initial state, when considering that molecules have different energies, and when including their interaction with the environment. We study this last situation by using stochastic Schr{\"o}dinger equations, both for Markovian and non-Markovian type of interactions.Comment: 21 pages, 5 figure

Migration scenarios and their demographic impacts for the EU member states

This deliverable both analyses the output for each migration scenario projected in Task 4.3 separately and compares different scenarios over time. At the total EU level FUME scenarios projected similar total population counts with small differences. The highest EU population in 2050 is projected by Scenario B - Recovery in Europe, stagnation in developing countries at around 518.8 million, and the lowest population is projected by No migration scenario at 387.2 million inhabitants. At national level, population sizes and compositions of the member states and the UK show more variability. Some countries are expected to experience sharp population decline at all FUME scenarios while others experience population growth. In the case of zero migration, all member states are expected to experience population decline, albeit at different paces. Migration flow composition in FUME scenarios is driven by the economical migration model presented in Deliverable 4.2 (D 4.2) and takes into account the size of diaspora and economic factors. Therefore, no surprising new origin-destination country pairs are emerging. However, when future migration flows are broken down by educational attainment the ranking of sending countries change in some cases, such as in France and Spain
