Transition Program from School to Employment in Youths with Intellectual Disability: Evaluation of the Irish Pilot Study E-IDEAS

open3siAim: The purpose of this pilot was to evaluate the effectiveness of the E-IDEAS curriculum, specifically designed for workplace inclusion of youths with intellectual disabilities (ID) and aimed to transfer social, communication, independent living and employment skills. Method: The curriculum was attended by 5 participants, and it was provided concurrently with five different work-placements across a period of six months. Two assessment tools were used to demonstrate the acquisition of such skills and an evidence-base improvement of their quality of life. Pre and postintervention standardized assessments were also taken for measuring the improvement in quality of life (through the San Mart n Scale) and adaptive behavior (through the Vineland-II Adaptive Behavior Scale). Results: The data collected showed increases in the acquisition of such skills. Evidence of maintenance and generalization were also demonstrated. Conclusion: Implications for practice and further research are discussed.openTraina I, Mannion A, Leader GTraina I, Mannion A, Leader

State reconstruction by on/off measurements

We demonstrate a state reconstruction technique which provides either the Wigner function or the density matrix of a field mode and requires only avalanche photodetectors, without any phase or amplitude discrimination power. It represents an alternative, of simpler implementation, to quantum homodyne tomography.Comment: 6 pages, 4 figures, revised and enlarged versio

Quantum state reconstruction using binary data from on/off photodetection

The knowledge of the density matrix of a quantum state plays a fundamental role in several fields ranging from quantum information processing to experiments on foundations of quantum mechanics and quantum optics. Recently, a method has been suggested and implemented in order to obtain the reconstruction of the diagonal elements of the density matrix exploiting the information achievable with realistic on/off detectors, e.g. silicon avalanche photo-diodes, only able to discriminate the presence or the absence of light. The purpose of this paper is to provide an overview of the theoretical and experimental developments of the on/off method, including its extension to the reconstruction of the whole density matrix.Comment: revised version, 11 pages, 6 figures, to appear as a review paper on Adv.

Coil embolization as an alternative endovascular approach for ruptured superficial femoral artery aneurysms

Purpose: True aneurysms of the superficial femoral artery (SFAA) are rare and, the endovascular approach using covered stents has gained more popularity. We report an endovascular alternative using embolization coils for treatment of a ruptured SFAA. Case description: An 88-old male admitted for a ruptured true SFAA (67×52mm in diameter and 70mm in length) presenting with painful mass pulsating in the proximal third of the left thigh. His surgical history consisted of an infrarenal abdominal aneurysm treated by open surgery and an ipsilateral popliteal aneurysm treated with prosthetic bypass by a medial approach; this was revealed to be occluded at the CT scan evaluation. The patient was asymptomatic for limb ischaemia, therefore we decided to perform embolization of the SFA with coils (MReye®Embolization Coil, Cook Medical, Bloomington,USA). Under local anaesthesia, via a 5-Fr sheath and an antegrade approach, coils were deployed first at the distal neck of the SFAA and then to its proximal neck. On the angiogram, complete aneurysm sac thrombosis with no leaks was achieved. At 6-month follow-up, the SFAA remained occluded, and the patient had not developed any sign of limb ischaemia. Conclusion: Coil embolization of SFAA in selected cases represents a feasible and safe endovascular alternative

Native NIR-emitting single colour centres in CVD diamond

Single-photon sources are a fundamental element for developing quantum technologies, and sources based on colour centres in diamonds are among the most promising candidates. The well-known NV centres are characterized by several limitations, thus few other defects have recently been considered. In the present work, we characterize in detail native efficient single colour centres emitting in the near infra-red in both standard IIa single-crystal and electronic-grade polycrystalline commercial CVD diamond samples. In the former case, a high-temperature annealing process in vacuum is necessary to induce the formation/activation of luminescent centres with good emission properties, while in the latter case the annealing process has marginal beneficial effects on the number and performances of native centres in commercially available samples. Although displaying significant variability in several photo physical properties (emission wavelength, emission rate instabilities, saturation behaviours), these centres generally display appealing photophysical properties for applications as single photon sources: short lifetimes, high emission rates and strongly polarized light. The native centres are tentatively attributed to impurities incorporated in the diamond crystal during the CVD growth of high-quality type IIa samples, and offer promising perspectives in diamond-based photonics.Comment: 27 pages, 10 figures.

Direct experimental observation of nonclassicality in ensembles of single photon emitters

In this work we experimentally demonstrate for the first time a recently proposed criterion adressed to detect nonclassical behavior in the fluorescence emission of ensembles of single-photon emitters. In particular, we apply the method to study clusters of NV centres in diamond observed via single-photon-sensitive confocal microscopy. Theoretical considerations on the behavior of the parameter at any arbitrary order in presence of poissonian noise are presented and, finally, the opportunity of detecting manifold coincidences is discussed

Towards joint reconstruction of noise and losses in quantum channels

The calibration of a quantum channel, i.e. the determination of the transmission losses affecting it, is definitely one of the principal objectives in both the quantum communication and quantum metrology frameworks. Another task of the utmost relevance is the identification, e.g. by extracting its photon number distribution, of the noise potentially present in the channel. Here we present a protocol, based on the response of a photon-number-resolving detector at different quantum efficiencies, able to accomplish both of these tasks at once, providing with a single measurement an estimate of the transmission losses as well as the photon statistics of the noise present in the exploited quantum channel. We show and discuss the experimental results obtained in the practical implementation of such protocol, with different kinds and levels of noise.Comment: 6 pages, 4 figure
