Changes in neural drive to calf muscles during steady submaximal contractions after repeated static stretches
2021
Key points: Repeated static-stretching interventions consistently increase the range of motion about a joint and decrease total joint stiffness, but findings on the changes in muscle and connective-tissue properties are mixed. The influence of these stretch-induced changes on muscle function at submaximal forces is unknown. To address this gap in knowledge, the changes in neural drive to the plantar flexor muscles after a static-stretch intervention were estimated. Neural drive to the plantar flexor muscles during a low-force contraction increased after repeated static stretches. These findings suggest that adjustments in motor unit activity are necessary at low forces to accommodate reduct…
Non-invasive Spatial Mapping of Frequencies in Atrial Fibrillation: Correlation With Contact Mapping
2021
[EN] Introduction: Regional differences in activation rates may contribute to the electrical substrates that maintain atrial fibrillation (AF), and estimating them non-invasively may help guide ablation or select anti-arrhythmic medications. We tested whether non-invasive assessment of regional AF rate accurately represents intracardiac recordings. Methods: In 47 patients with AF (27 persistent, age 63 +/- 13 years) we performed 57-lead non-invasive Electrocardiographic Imaging (ECGI) in AF, simultaneously with 64-pole intracardiac signals of both atria. ECGI was reconstructed by Tikhonov regularization. We constructed personalized 3D AF rate distribution maps by Dominant Frequency (DF) ana…
Patterns of care and cost profiles of women with breast cancer in Italy: EPICOST study based on real world data
2020
Objectives To estimate total direct health care costs associated to diagnosis and treatment of women with breast cancer in Italy, and to investigate their distribution by service type according to the disease pathway and patient characteristics. Methods Data on patients provided by population-based Cancer Registries are linked at individual level with data on health-care services and corresponding claims from administrative databases. A combination of cross-sectional approach and a threephase of care decomposition model with initial, continuing and final phases-of-care defined according to time occurred since diagnosis and disease outcome is adopted. Direct estimation of cancer-related cost…

Interactive data-driven multiobjective optimization of metallurgical properties of microalloyed steels using the DESDEO framework
2023
Solving real-life data-driven multiobjective optimization problems involves many complicated challenges. These challenges include preprocessing the data, modelling the objective functions, getting a meaningful formulation of the problem, and supporting decision makers to find preferred solutions in the existence of conflicting objective functions. In this paper, we tackle the problem of optimizing the composition of microalloyed steels to get good mechanical properties such as yield strength, percentage elongation, and Charpy energy. We formulate a problem with six objective functions based on data available and support two decision makers in finding a solution that satisfies them both. To …
Design and Performance Evaluation of a High Power-Density EMI Filter for PWM Inverter-Fed Induction-Motor Drives
2016
This paper presents the design of an electromagnetic interference (EMI) filter for a low-voltage high-current induction-motor drives supplied by dc power grids. In order to effectively design the EMI filter, a suitable common-mode/differential-mode (CM/DM) separation technique has been used. Due to the high operating currents, the software-based separation technique using time-domain measurements has been applied. The proposed technique allows the CM and DM sections of the EMI filter to be properly selected in a more economical way, i.e., without the need of a dedicated hardware or costly radio frequency (RF) instrumentation. The design has been done according to a power-density criterion. …
Epidemiology, Physiology and Clinical Approach to Sleepiness at the Wheel in OSA Patients: A Narrative Review
2022
Sleepiness at the wheel (SW) is recognized as an important factor contributing to road traffic accidents, since up to 30 percent of fatal accidents have been attributed to SW. Sleepiness-related motor vehicle accidents may occur both from falling asleep while driving and from behavior impairment attributable to sleepiness. SW can be caused by various sleep disorders but also by behavioral factors such as sleep deprivation, shift work and non-restorative sleep, as well as chronic disease or the treatment with drugs that negatively affect the level of vigilance. An association between obstructive sleep apnea (OSA) and motor vehicle accidents has been found, with an increasing risk in OSA pati…
ENABLING LOCAL GOVERNMENTS TO DESIGN AND IMPLEMENT ANTI-CORRUPTION STRATEGIES THROUGH DYNAMIC PERFORMANCE MANAGEMENT AND GOVERNANCE. A CASE-STUDY OF …
2021
Lo scopo principale di questa ricerca è quello di inquadrare le possibili relazioni causali fra corruzione negli approvvigionamenti pubblici e performance delle amministrazioni locali. A tal fine, viene adottato un disegno di ricerca che integra dinamicamente metodi quantitativi e qualitativi in ogni fase del processo di studio. Gli approcci Dynamic Performance Management (DPM) e Governance (DPG), supportati da interviste approfondite non-strutturate, modellazioni formali e simulazioni quantitative, sono qui adottati per analizzare un caso di studio rappresentativo di un piccolo comune italiano in cui si sono verificati alcuni episodi di corruzione nelle attività di approvvigionamento nei p…
Excel ja laskenta pilvipalveluissa
2013
Tutkielma esittelee ja vertailee taulukkolaskenta-ohjelmien ohjelmointimahdollisuuksia. Taulukkolaskentaohjelmia on mahdollisuus käyttää perinteisenä työpöytäsovelluksena, pilvipalveluna verkkoselaimella sekä etäpalvelimen asiakasohjelmalla. Lisää suoritustehoa on saatavilla rinnakkaislaskennalla ja pilvipalveluntarjoajilta. The thesis examines and compares spreadsheet programs and their programming options. Spreadsheet programs have the option to use as a traditional desktop application, a web browser, as well as run the application server with remote client. More processing power is available by using parallel computing and from cloud service providers.
Peer selection and influence : Students’ interest-driven socio-digital participation and friendship networks
2020
Digital technologies have been increasingly embedded in students’ everyday lives. Interest-driven socio-digital participation (ISDP) involves students’ pursuit of interests mediated by computers, social media, the internet, and mobile devices’ integrated systems.ISDPis likely to intertwine closely with young people’s social networks that has been scarcely studied quantitatively. To close this gap, the present paper investigated students’ peer selection and influence effects of the intensity of their ISDP and friendship networks. We collected two-wave data by administering a peer nomination to trace students’ friendship networks with peers and a self-reported questionnaire to examine student…
