A distributed visualization system for crowd simulations1
2011
The visualization system of large-scale crowd simulations should scale up with both the number of visuals views of the virtual world and the number of agents displayed in each visual. Otherwise, we could have large scale crowd simulations where only a small percentage of the population is displayed. Several approaches have been proposed in order to efficiently render crowds of animated characters. However, these approaches either render crowds animated with simple behaviors or they can only support a few hundreds of user-driven entities. In this paper, we propose a distributed visualization system for large crowds of autonomous agents that allows the visualization of crowds animated with co…
An Initial Security Analysis of the Personal Transaction Protocol
2003
Our society is becoming increasingly dependent on the rapid access and processing of information. The number of handheld mobile devices with access to the Internet and network-based software and services is exploding. Research indicates [1] that by the end of 2002 there will be over 1 billion mobile phone owners globally with Internet access, and that this number is going to grow exponentially in the nearest future. By 2006 the number of interconnected mobile device users is expected exceed the worldwide Internet subscriber population. It is estimated that in a few years there will be three times as many of these devices worldwide as personal computers.
Orthognathic surgery and aligners. A comparative assessment of periodontal health and quality of life in postsurgical orthodontic treatment with alig…
2023
Removable clear aligners have become very popular in the last few decades, but they are still little used in the field of orthognathic surgery (OS). The objective of this study was to compare periodontal health and quality of life (QoL) associated to postsurgical orthodontic treatment. Patients with dentofacial deformities undergoing OS were randomly allocated to receive postsurgical orthodontic treatment with either fixed orthodontic appliances or Invisalign. The main outcomes were periodontal health and QoL. Plaque index, probing depth and bleeding on probing were assessed as periodontal health indicators. QoL was assessed through the Orthognathic Quality of Life Questionnaire (OQLQ-22) a…
City-forming Rome: mappe di una città da ri-colonizzare
2017
L’unità di ricerca di Palermo è stata partecipe dell’iniziativa “ROMA 20-25. Nuovi cicli di vita per la Metropoli”, che ha chiamato ventiquattro scuole di architettura, università italiane e internazionali, a interpretare il presente urbano di Roma e immaginarne il futuro attraverso un workshop internazionale di progettazione e una mostra. Il progetto “ROMA 20-25 Nuovi cicli di vita per la Metropoli” è stato promosso dall’Assessorato alla Trasformazione Urbana del Comune di Roma e dal MAXXI, Museo Nazionale delle Arti del XXI secolo. L’area di progetto che è stata affidata all’UdR di Palermo è quella del quadrante n.12, caratterizzata dall’essere attraversata da est a ovest dal fiume Tevere…
Cisplatin plus weekly vinorelbine versus cisplatin plus vinorelbine on days 1 and 8 in advanced non-small cell lung cancer: a prospective randomized …
2008
Summary Purpose A phase III randomized trial was carried out to compare two schedules of the vinorelbine (VNR)–cisplatin (CDDP) regimen in patients with locally advanced unresectable poor prognosis stage IIIB or metastatic stage IV non-small cell lung cancer. The primary endpoints were overall survival (OS) and analysis of toxicity, while secondary endpoints included response rates, time-to-progression (TTP) and quality of life (QoL). Patients and methods Eligible patients were randomized to receive: (a) VNR 25 mg/m 2 on day 1, 8 and 15 plus CDDP 100 mg/m 2 on day 1 every 4 weeks or (b) VNR 30 mg/m 2 on day 1 and 8 plus CDDP 80 mg/m 2 on day 1 every 3 weeks. All patients were chemotherapy-n…
The market of migrant smuggling through Libya to Southern Italy since 2011: filling the knowledge gap as a human rights' strategy
2018
The first formal distinction between human smuggling and trafficking in international law was made with the signing in December 2000 of the Palermo Protocols. These definitions have influenced and shaped most of the academic research, discourse, methodology and language on human smuggling and trafficking. In turn, an understanding of the formal definitions of these crimes is necessary to appreciate their influence on policies and therefore their effects on the individuals and institutions involved (Campana and Varese, 2015). The argument at the basis of this thesis is that academic research on especially migrant smuggling has often blindly adopted the above-mentioned definitions as a given-…
Towards the standardization of mitochondrial proteomics: the Italian mt-HPP initiative
2017
The mitochondrial Human Proteome Project aims at understanding the function of the mitochondrial proteome and its crosstalk with the proteome of other organelles. Being able to choose a suitable and validated enrichment protocol of functional mitochondria, based on the specific needs of the downstream proteomics analysis, would greatly help the researchers in the field. Mitochondrial fractions from ten model cell lines were prepared using three enrichment protocols and analyzed on seven different LC-MS/MS platforms. All data were processed using neXtProt as reference database. The data are available for the Human Proteome Project purposes through the ProteomeXchange Consortium with the iden…
Analysis and Performance Evaluation of the IEEE 802.16 ARQ Mechanism
2008
The IEEE 802.16 standard defines the ARQ mechanismas a part of the MAC layer. The functioning of the ARQmechanism depends on a number of parameters. The IEEE802.16 specification defines them but it does not provide concrete values and solutions. This paper studies the key features and parameters of the 802.16 ARQ mechanism. In particular, we consider a choice for the ARQ feedback type, an algorithm to build block sequences, the ARQ feedback intensity, a scheduling of the ARQ feedbacks and retransmissions, the ARQ block rearrangement, ARQ transmission window and the ARQ block size. We ran simulation scenarios to study these parameters and how they impact the performance of application protoc…
Pain neuroscience education and physical exercise for patients with chronic spinal pain in primary healthcare: a randomised trial protocol.
2019
AbstractBackgroundChronic musculoskeletal pain affects more than 20% of the population, and the prevalence is increasing, causing suffering, loss of quality of life, disability, and an enormous expenditure on healthcare resources. The most common location for chronic pain is the spine. Many of the treatments used are mainly passive (pharmacological and invasive) and poor outcomes. The treatments currently applied in the public health system do not comply with the recommendations of the main clinical practice guidelines, which suggest the use of educational measures and physical exercise as the first-line treatment. A protocol based on active coping strategies is described, which will be eva…
CareACT - internet-based intervention for enhancing the psychological well-being of elderly caregivers – a study protocol of a controlled trial
2019
Abstract Background The rapid increase in the number of elderly family caregivers underlines the need for new support systems. Internet-delivered psychological interventions are a potential approach, as they are easy to access for family caregivers who are often homebound with their care recipient. This study examines the relative effectiveness of an internet-based acceptance and commitment therapy (ACT) intervention or a standardized institutional rehabilitation program, first, in reducing depressive symptoms, and second, in improving the well-being and quality of life of elderly family caregivers compared to a control group receiving support from voluntary family caregiver associations.
