Topological Information, Flux Balance Analysis, and Extreme Pathways Extraction for Metabolic Networks Behaviour Investigation

2011

In recent years biological processes modeling and simulation have become two key issues in analyzing complex cellular systems. Information about metabolic networks is often incomplete, since a large portion of available data is ignored by its probabilistic nature. The main objective of this work is to investigate metabolic networks behavior in terms of their fault tolerance capabilities as random removal of network nodes and high-connectivity-degree node deletion aimed at compromising or modifying network activity. This paper proposes a software framework, namely CEllDataLaB, containing three tasks to perform the structural and functional analysis: topological analysis, flux balance analysi…

Normalised compression distance and evolutionary distance of genomic sequences: comparison of clustering results

2009

Genomic sequences are usually compared using evolutionary distance, a procedure that implies the alignment of the sequences. Alignment of long sequences is a time consuming procedure and the obtained dissimilarity results is not a metric. Recently, the normalised compression distance was introduced as a method to calculate the distance between two generic digital objects and it seems a suitable way to compare genomic strings. In this paper, the clustering and the non-linear mapping obtained using the evolutionary distance and the compression distance are compared, in order to understand if the two distances sets are similar.

Il tarantismo in Sicilia

2017

Il testo prende in esame il complesso di materiali editi e inediti (fonti storiche e archivistiche, documenti musicali, testimonianze etnografiche) che attestano la presenza del tarantismo in Sicilia dalla metà del Seicento alla fine dell’Ottocento. Il caso siciliano viene quindi inquadrato nell’ambito dell’ampia letteratura che ruota intorno al fenomeno, a partire dal classico studio di Ernesto De Martino fino al dibattito sull’interpretazione del fenomeno fra i poli dell’esorcismo e della possessione, dovuto soprattutto all’etnomusicologo francese Gilber Rouget. L’analisi viene quindi estesa alla tradizione dei guaritori dei morsi di serpenti (i ciaràuli), che con il tarantismo condividon…

Ornamento e Architettura. L'estetica funzionalistica di Louis H. Sullivan

2010

The present volume offers an introduction to and advances a new interpretation of the aesthetic of Louis Henry Sullivan(1856-1924). Sullivan is universally known as one of the most important American architects, possibly even the greatest one of the 19th century. Scholars of the Modern Movement have misinterpreted his motto “form follows function” and have hailed him as the “father of functionalism”. Sullivan, however, attributed to the concepts of “form”, “function” and “suitability” a higher and more poetic meaning than the other architects of the Chicago School, among whom the debate on such issues, as related to Gottfried Semper’s theories and evolutionist doctrines, was quite heated. N…

Cognitive vulnerability to depressive symptoms in children: the protective role of self-efficacy beliefs in a multi-wave longitudinal study.

2014

The current multi-wave longitudinal study on childhood examined the role that social and academic self-efficacy beliefs and cognitive vulnerabilities play in predicting depressive symptoms in response to elevations in idiographic stressors. Children (N = 554; males: 51.4 %) attending second and third grade completed measures of depressive symptoms, negative cognitive styles, negative life events, and academic and social self-efficacy beliefs at four time-points over 6 months. Results showed that high levels of academic and social self-efficacy beliefs predicted lower levels of depressive symptoms, whereas negative cognitive styles about consequences predicted higher depression. Furthermore,…

Childhood Maltreatment, Pathological Personality Dimensions, and Suicide Risk in Young Adults

2018

Several studies have demonstrated that child maltreatment (psychological, physical, and sexual abuse, and neglect) may be a significant factor in the development of pathological personality traits that increase the risk for suicidal ideation and behavior from adolescence to adulthood. Currently, the challenge is to understand how different forms of early negative experiences render an individual prone to develop specific personality traits and, in turn, be more vulnerable to suicide risk. To understand the relationship between childhood maltreatment and personality dimensions in suicide risk, our study aims to explore the role of self-criticism and dependency, two different pathological per…

Random Stability of an Additive-Quadratic-Quartic Functional Equation

2010

Using the fixed point method, we prove the generalized Hyers-Ulam stability of the following additive-quadratic-quartic functional equation f(x+2y)+f(x−2y)=2f(x+y)+2f(−x−y)+2f(x−y)+2f(y−x)−4f(−x)−2f(x)+f(2y)+f(−2y)−4f(y)−4f(−y) in complete random normed spaces.

Mediterranean Diet as a tool for achieving successful ageing

2017

Targeted interventions to slow or postpone ageing and to favour an active life expectancy represent the new perspectives in ageing investigation. Some mechanisms that delay or prevent the onset of ageing disabilities and pathologies have been identified. In general, maintaining a healthy lifestyle seems to reduce many risk factors. In particular, eating habits represent the most concrete and low-cost method to address ageing. Of all dietary habits analysed, the Mediterranean diet has received much attention since it has consistently proven its beneficial influence on health and longevity. The Mediterranean diet is characterized by low glycaemic index and low animal protein intake, it is ric…

Healthy eating as a strategy to achieve successful ageing: focus on Mediterranean diet and functional foods.

People want to live longer. To date, it is impossible not to grow older, but it is desirable to get older in good health, avoiding age-related disabilities. To do this, it is necessary to have a healthy lifestyle which can limit the damage caused by the environmental hazards that face us each day. In humans, healthy ageing and longevity are modulated by a fortunate interaction between genetic and environmental factors. Regarding the latter, physical activity and healthy dietary habits are the most important modifiable factors that can affect the maintenance of a healthy ageing phenotype. A feasible diet that reduces the risk of ageing-related diseases, promoting health ageing and longevity,…
