Resolution of the mystery of counter-intuitive photon correlations in far off-resonance emission from a quantum dot-cavity system

Cavity quantum-electrodynamics experiments using an atom coupled to a single radiation-field mode have played a central role in testing foundations of quantum mechanics, thus motivating solid-state implementations using single quantum dots coupled to monolithic nano-cavities. In stark contrast to their atom based counterparts, the latter experiments revealed strong cavity emission, even when the quantum dot is far off resonance. Here we present experimental and theoretical results demonstrating that this effect arises from the mesoscopic nature of quantum dot confinement, ensuring the presence of a quasi-continuum of transitions between excited quantum dot states that are enhanced by the cavity mode. Our model fully explains photon correlation measurements demonstrating that photons emitted at the cavity frequency are essentially uncorrelated with each other even though they are generated by a single quantum dot.Comment: 5 pages, 4 figure

GYNOCARE Update: Modern Strategies to Improve Diagnosis and Treatment of Rare Gynecologic Tumors—Current Challenges and Future Directions

More than 50% of all gynecologic tumors can be classified as rare (defined as an incidence of ≤6 per 100, 000 women) and usually have a poor prognosis owing to delayed diagnosis and treatment. In contrast to almost all other common solid tumors, the treatment of rare gynecologic tumors (RGT) is often based on retrospective studies, expert opinion, or extrapolation from other tumor sites with similar histology, leading to difficulty in developing guidelines for clinical practice. Currently, gynecologic cancer research, due to distinct scientific and technological challenges, is lagging behind. Moreover, the overall efforts for addressing these challenges are fragmented across different European countries and indeed, worldwide. The GYNOCARE, COST Action CA18117 (European Network for Gynecological Rare Cancer Research) programme aims to address these challenges by creating a unique network between key stakeholders covering distinct domains from concept to cure: basic research on RGT, biobanking, bridging with industry, and setting up the legal and regulatory requirements for international innovative clinical trials. On this basis, members of this COST Action, (Working Group 1, “Basic and Translational Research on Rare Gynecological Cancer”) have decided to focus their future efforts on the development of new approaches to improve the diagnosis and treatment of RGT. Here, we provide a brief overview of the current state of-the-art and describe the goals of this COST Action and its future challenges with the aim to stimulate discussion and promote synergy across scientists engaged in the fight against this rare cancer worldwide

No-vax, fake news, teorie della cospirazione, pseudoscienza. Un contributo sociologico all’analisi dell’infodemia

Il contributo è dedicato all'analisi del fenomeno dell'infodemia. Particolare attenzione è destinata al caso dei no-vax, delle fake news, delle teorie della cospirazione e della pseudoscienza. L'analisi teorica è condotta a partire dalla prospettiva della sociologia dell'immaginario e della sociologia fenomenologic

L’immaginario sociale della pandemia. Sacro, temporalità e "messa in scena del rischio"

This paper aims to analyze the pandemic phenomenon, understood as an imaginal and communicative object. In the first part of the essay, the theme of contagion is related to the dimension of the sacred and its peculiar aspects concerning temporality. In the second part, the coronavirus phenomenon is analyzed within the theoretical framework of the sociology of risk with particular attention to the “staging of the reality of global risk”, in the words of Ulrich Beck. The complexity of the phenomenon is revealed by the scientific predictions in an arena of experts often positioned on opposite sides. The last part of this essay is focused on temporality within scientific predictions

Analysis of stable carbon and nitrogen isotopes as a tool for assessing the environmental impact of aquaculture: a case study from the western Mediterranean

Stable carbon and nitrogen isotope ratios (13C/12C and 15N/14N) of in situ dominant primary producers and consumers were investigated to assess the impact on a natural ecosystem of a land-based fish farm along the south-western coast of Sicily (Italy). The putatively impacted area close to the farm along outfall was compared with other locations at increasing distances from the outfall. Carbon and mainly nitrogen stable isotopes revealed evidence of widespread aquaculture waste in the study site: benthic organisms collected in the impacted area showed more enriched d15N signatures than those at greater distances from the outfall, suggesting a large contribution of aquaculture waste to the food web. By contrast, both nekton-benthic and pelagic organisms seemed to be less influenced by discharge, probably due to their mobile habit
