Diffusion of muonic hydrogen in hydrogen gas and the measurement of the 1s hype...

The CREMA collaboration is pursuing a measurement of the ground-state hyperfine splitting (HFS) in muonic hydrogen (μp) with 1 ppm accuracy by means of pulsed laser spectroscopy. In the proposed experiment, the μp atom is excited by a laser pulse from the singlet to the triplet hyperfine sub-levels, and is quenched back to the singlet state by an inelastic collision with a H2 molecule. The resulting increase of...

Minimizing ruin probability under dependencies for insurance pricing

In this work the ruin probability of the Lundberg risk process is used as a criterion for determining the optimal security loading of premia in the presence of price-sensitive demand for insurance. Both single and aggregated claim processes are considered and the independent and the dependent cases are analyzed. For the single-risk case, we show that the optimal loading does not depend on the initial reserve. I...

Reinsurance of multiple risks with generic dependence structures

We consider the optimal reinsurance problem from the point of view of a direct insurer owning several dependent risks, assuming a maximal expected utility criterion and independent negotiation of reinsurance for each risk. Without any particular hypothesis on the dependency structure, we show that optimal treaties exist in a class of independent randomized contracts. We derive optimality conditions and show tha...

A multiple-indicator latent growth mixture model to track courses with low-qual...

This paper describes a multi-indicator latent growth mixture model built on the data collected by a large Italian university to track students’ satisfaction over time. The analysis of the data involves two steps: first, a pre-processing of data selects the items to be part of the synthetic indicator that measures students’ satisfaction; the second step then retrieves heterogeneity that allows the identification...

Development of gastronomic strategies for the application and valorization of n...

Strategic innovation must anticipate consumer’s acceptance and commercial potential in their design process. The main objective of this study was to develop gastronomic applications with the use of water-in-oil (60 to 65% lipid phase) innovative inverse emulsion prototypes (which preserve expensive/seasonal raw materials and value surplus/regional by-products) (1), appealing to the final consumer. Five emulsion...

Leprosy presenting as remitting seronegative symmetrical synovitis with pitting...

Background: Leprosy typically manifests with skin and peripheral nerve involvement. Musculoskeletal complaints are the third most common, and can be the sole presenting manifestation. They range from arthralgia/arthritis in reactional states to full mimics of systemic rheumatic diseases. Remitting Seronegative Symmetrical Synovitis with Pitting Oedema syndrome has only been described once in a patient with alre...

Gli azulejos nell’opera di Athos Bulcão e Gio Ponti

O uso de elementos cerâmicos na arquitetura sempre foi um tema visto em vários projetos. Estes elementos, chamados azulejo, muitas vezes estão conectados à arquitetura moderna. Na Itália, este revestimento chamado de piastrelle, é um elemento recorrente na arquitetura e está detrás de uma ideia de modernização técnica e formal. Este artigo tem como proposta uma análise através da obra de dois arquitetos, um ita...

Biomares, a LIFE project to restore and manage the biodiversity of Prof. Luiz S...

The Marine Park Prof. Luiz Saldanha, in the coast of Arrabida, is the first marine park in continental Portugal. This area is a Nature 2000 site and is considered to be a hotspot for European marine biodiversity. In 2005, the management plan of the park was implemented, ending several habitat menaces, thereby allowing an application to the LIFE-NATURE Programme. The LIFE-BIOMARES project aimed at the restoratio...

Persistent varicella as the initial manifestation of systemic lymphoma

Varicella is a common benign childhood disease that often presents in adolescents and adults in a more severe form. We report a previously healthy 50-year-old man who developed multiple necrotic cutaneous ulcers associated with fever, asthenia and anorexia. Physical examination revealed few tense hemorrhagic vesicles on the trunk and necrotic cutaneous ulcers scattered over the entire cutaneous surface. After t...
