Speeding up the Consensus Clustering methodology for microarray data analysis
2010
Abstract Background The inference of the number of clusters in a dataset, a fundamental problem in Statistics, Data Analysis and Classification, is usually addressed via internal validation measures. The stated problem is quite difficult, in particular for microarrays, since the inferred prediction must be sensible enough to capture the inherent biological structure in a dataset, e.g., functionally related genes. Despite the rich literature present in that area, the identification of an internal validation measure that is both fast and precise has proved to be elusive. In order to partially fill this gap, we propose a speed-up of Consensus (Consensus Clustering), a methodology whose purpose…
Proceedings of the Closed Round Table and Italian Consensus on the Medication-Related Osteonecrosis of Jaws (MRONJ) at the Symposium of Italian Socie…
2019
On 20 October 2018 a Closed Round Table brought together a wide range of stakeholders from several medical disciplines, including academic experts, dentists, oncologists, maxillo-facial surgeons, oral surgeons, radiologists, under the technical and scientific coordination of Giuseppina Campisi (for SIPMO) and Giacomo Oteri (for Italian Society of Oral Surgery- SIdCO).
Dealing with uncertainty in consensus protocol
2009
Recent results on Consensus protocols for networks are presented. The basic tools and the main contribution available in the literature are considered, together with some of the related challenging aspects: estimation in networks and how to deal with disturbances is considered. Motivated by applications to sensor, peer-to-peer, and ad hoc networks, many papers have considered the problem of estimation in a consensus fashion. Here, the Unknown But Bounded (UBB) noise affecting the network is addressed in details. Because of the presence of UBB disturbances convergence to equilibria with all equal components is, in general, not possible. The solution of the $\epsilon$-consensus problem, where…
Logical Consensus for Distributed Network Agreement
2008
In this paper we introduce a novel consensus mechanism where agents of a network are able to share logical values, or Booleans, representing their local opinions on e.g. the presence of an intruder or of a fire within an indoor environment. Under suitable joint conditions on agents? visibility and communication capability, we provide an algorithm generating a logical linear consensus system that is globally stable. The solution is optimal in terms of the number of messages to be exchanged and the time needed to reach a consensus. Moreover, to cope with possible sensor failure, we propose a second design approach that produces robust logical nonlinear consensus systems tolerating a maximum n…
Toward a Society of Robots: Behavior, Misbehavior, and Security
2010
In this article, we consider how a very large numbers of robots, differing in their bodies, sensing, and intelligence, may be made to coexist, communicate, and compete fairly toward achieving their individual goals, i.e., to build a society of robots. We discuss some characteristics that the rules defining acceptable social behaviors should possess. We consider threats that may be posed to such a society by the misbehaviors of some of its members, either due to faults or malice, and the possibility to detect and isolate them through cooperation of peers. The article presents examples of motion control protocols, for arbitrarily large groups of heterogeneous robots. We discuss intrusion dete…
Building Consensus. An introduction to a rhetorical approach
2016
The contemporary debate on democracy shows two points of view: the “deliberative” one and the “agonistic” one. The first one is related to the classical tradition that considers Habermas as its reference point. It emphasizes the role of rational deliberation as a means to produce a legitimate and binding consensus. In contrast, the second one draws its inspiration from C. Schmitt, and considers conflict and disagreement as unavoidable conditions of democratic life. Despite their obvious differences, these two theoretical models have a conception of rhetoric in common that is subjected to, or at least excluded from, the full exercise of argumentative rationality. We propose an interpretation…
Consensus On Women'S Health Aspects Of Polycystic Ovary Syndrome (Pcos)
2012
Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in females with a high prevalence. The etiology of this heterogeneous condition remains obscure and its phenotype expression varies. Two, widely cited, previous ESHRE/ASRM-sponsored PCOS consensus workshops focused on diagnosis (published in 2004) and infertility management (published in 2008). The present third PCOS consensus paper summarizes current knowledge and identifies knowledge gaps regarding various women's health aspects of PCOS. Relevant topics addressed-all dealt with in a systematic fashion-include adolescence, hirsutism and acne, contraception, menstrual cycle abnormalities, quality of life, ethnicity, preg…
Appropriateness criteria for the management of lipid-lowering therapy with alirocumab in high cardiovascular risk patients. The opinion of a multidis…
2020
High levels of LDL cholesterol (LDL-C) represent a causal factor for cardiovascular diseases on an atherosclerotic basis, with a direct correlation between these and mortality or cardiovascular events, such that the reduction of both is associated proportionally and linearly with the reduction of LDL-C.Statins and ezetimibe are used for LDL-C lowering but may not be sufficient to achieve the targets defined by the ESC/EAS guidelines, which recommend use of PCSK9 inhibitors for further LDL-C reduction in patients not at goal.This project submitted 86 clinical scenarios to a group of experts, cardiologists, internists and lipidologists, collecting their opinion on the appropriateness of diffe…
Adherence to colchicine treatment and colchicine resistance in a multicentric FMF national cohort
2020
Introduction: Colchicine is the standard treatment for Familiar Mediterranean Fever (FMF), however about 5% of patients (pts) experience colchicine resistance. There is no standard definition of colchicine resistance. Recently a panel of experts elaborated a new definition based on a Delphi consensus approach. Objectives: We aim to describe main features of the disease and clinical outcome of a cohort of FMF pts with particular interest on the colchicine resistance and tolerability according to the definitions proposed by the recent consensus.
A System Dynamics Approach to Analysing the Effect of Clientelism on Public Organizations Performance in Italy
2010
This paper tries to analyse the effects of political clientelism on the performance of public utilities and organizations in Italy. Shortly, clientelism consists in a series of reciprocal convenience-based relationships between politicians and individuals, commanding unequal resources and involving mutually beneficial transactions in terms of economic, social and political consequences. The motivation of this research stems from the fact that analysing the effect of clientelism may contribute in (1) improving the quality of electoral strategies and the resulting public policies and (2) managing the performance of public organizations according to a sustainable perspective. Hence, the key is…
