L’accesso alla CNC non ‘blinda’ gli amministratori
No full textL’ordinanza in commento è, a quanto consta, la prima ad affrontare ex professo il delicato quesito relativo alla facoltà dei soci di revocare gli amministratori nonostante – o, forse, proprio in ragione del fatto che – questi abbiano intrapreso il percorso della composizione negoziata della crisi. La risposta del Tribunale di Genova è stata nel senso della perdurante operatività del principio di libera revocabilità dell’organo amministrativo in ragione dell’inapplicabilità, neppure in via analogica, della disposizione eccezionale di cui all’art. 120-bis, 4° comma, CCII, nonché dell’impossibilità di eludere una scelta legislativa consapevole mediante il ricorso a misure cautelari atipiche ex art. 19 CCII. La nota, dopo aver ripercorso i passaggi salienti della motivazione, si propone di offrire alcuni spunti di riflessione di carattere sistematico anche in vista dell’attuazione della delega prevista dall’art. 19 della c.d. “Legge Capitali”
Fishery by-products as valuable source of bioactive compounds: optimization of supercritical fluid extraction process and extracts characterization in terms of fatty acids and vitamin D3
No full textFishery by-products represent a valuable yet underutilized source of bioactive lipids with potential applications in food,
nutraceutical, and cosmetic industries. In this context, Supercritical fluid extraction (SFE) represents a promising approach
for obtaining high-quality extracts without solvent-related safety concerns. This study aims at investigating a sustainable
process to obtain extracts rich in bioactive compounds for pharmaceutical and nutraceutical applications from fishing
by-products, referring to all the fish that are caught but do not satisfy the market requirements for size or shape. The
extraction parameters were determined using a 3-variables Box–Behnken Design (time, temperature and pressure). The
100 min, 400 bar and 40 °C process was selected and applied to five different fish species. In each extract vitamin D3
and 7-dehydrocholesterol were quantified using HPLC-DAD and the fatty acids profile was characterized in GC-MS. The
waste products, especially those from sardine and anchovy, exhibited a noteworthy vitamin D3, 7-dehydrocholesterol,
and omega-3 fatty acids composition. This research represents a further step in daily fishing waste reuse as a source of
high-value extract
A web-based solution for sales representative scheduling
No full textThis paper presents an approach to address the complex scheduling problem faced by sales representatives. Many scheduling and routing problems have been explored before in research but real-life applications often feature complex constraints and requirements. The problem we propose is a variant of the travelling salesman problem, in which customers must be visited multiple times over a long planning period at different intervals, with daily workload constraints, regularity and varying flexibility in the requirements, with the goal of minimizing the total travel distance. To tackle this challenge, which deviates significantly from classical routing problems, a genetic algorithm-based solution has been developed and integrated into a user-friendly web application. The algorithm effectively generates feasible and efficient schedules, considering several and diverse factors. Experimental results demonstrate the algorithm's ability to produce high-quality solutions, outperforming manual planning methods and the other tested approaches. The web application provides an intuitive interface for problem definition and solution visualization, facilitating user interaction and optional refinement
Profilazione e micro-targeting a scopo politico-elettorale nella prospettiva del diritto costituzionale
Full text linkMuovendo dalla trasformazione dei paradigmi comunicativi determinata dall’avvento della rete, il contributo si propone di esaminare le implicazioni derivanti dall’utilizzo degli strumenti di profilazione e di microtargeting in ambito politico-elettorale, riflettendo su come questi incidano sul libero esercizio del diritto di voto e sull’integrità della composizione del discorso pubblico specificatamente nel contesto italiano, da ultimo valutando se e come il recente Regolamento (UE) 2024/900 sia in grado di rappresentare una adeguata soluzione normativa alle criticità individuate
Exclusive photoproduction of excited ρ mesons decaying to four pions in ultraperipheral Pb–Pb collisions at sqrt(s_NN) = 5.02 TeV
No full textThe intense photon fluxes from relativistic nuclei provide an opportunity to study photonuclear interactions in ultraperipheral collisions. In particular, it allows for the investigations of excited, light-flavour vector mesons. The measurement of coherently photoproduced π+π−π+π− final states in ultraperipheral Pb–Pb collisions at sNN=5.02 TeV is presented for the first time. The cross section, d σ /d y , times the branching ratio (ρ→π+π+π−π−) is found to be 47.8 ± 2.3 (stat.) ± 7.7 (syst.) mb in the rapidity interval | y | < 0.5. The invariant mass distribution is not well described with a single Breit-Wigner resonance without an interference term. Including interference with a non-resonant contribution results in the mass and width values being too far from those reported in PDG, while the production of two interfering resonances, ρ (1450) and ρ (1700), also provides a good description of the data. The values of the masses ( m ) and widths (Γ) of the resonances extracted from the fit assuming two interfering resonances are m1=1385±14(stat.)±3(syst.) MeV/ c 2, Γ1=431±36(stat.)±82(syst.) MeV/ c 2, m2=1663±13(stat.)±22(syst.) MeV/ c 2 and Γ2=357±31(stat.)±49(syst.) MeV/ c 2, respectively. The measured cross sections times the branching ratios are compared to recent theoretical predictions
Securing IoE Environments with Semantic Data Stream Analysis and Behavioral Fingerprinting
No full textIn the landscape of Industry 5.0, Internet of Everything (IoE) networks are emerging as crucial components for connecting diverse industrial sensors and devices, expanding beyond traditional IoT boundaries to integrate people, processes, and data. However, this increased connectivity raises significant security concerns, as the growing complexity of IoE environments introduces new attack vectors and privacy risks. Additionally, the integration of heterogeneous devices and data sources presents both technical and semantic interoperability challenges, requiring robust mechanisms for meaningful data interpretation and secure exchange. This paper, developed within the HOMEY project, presents an architecture for gathering and monitoring semantic data streams in IoE environments, addressing both interoperability and security challenges. Our approach leverages Knowledge Graphs to represent sensor metadata, locations, access rights, and operational contexts, enabling dynamic stream monitoring and data querying. An approach based on Federated Learning allows distributed behavioral fingerprinting of IoE devices, which is exploited on top of the platform to perform anomaly detection from real-time data streams. The approach enhances reliable, privacy-preserving anomaly detection, contributing to the security and resilience of next-generation industrial IoE ecosystems

No full textPsychometric Testing of the Mutuality Scale in Patients and Caregiver Dyads After the Onset of Coronary Heart Disease
Full text linkThis study investigates the psychometric properties of the Mutuality Scale in a sample of patient-caregiver dyads following a recent episode of coronary heart disease. A cross-sectional analysis was conducted. Factorial validity was tested with confirmatory factory analysis. Internal consistency reliability was investigated with the model-based internal consistency reliability index. Pearson's correlation coefficient was used to test convergent validity between mutuality and other theoretical and empirical variables associated with it. We included 150 patient-caregiver dyads (patient: mean age 65 years, 77% males, 71% married; caregiver: mean age 54 years, 21% males, 71% married). The CFA testing the theoretical four-factors (love, shared pleasurable activities, shared values, and reciprocity) of mutuality demonstrated adequate fit to the data in both the patient and caregiver version of the scale. Reliability estimates were adequate for the whole scale (model-based internal consistency index = 0.95). Significant positive correlations were observed between mutuality and self-care behaviors, and caregiver preparedness, supporting convergent validity. The Mutuality Scale demonstrated satisfactory structural and convergent validity and reliability in patient-caregiver dyads after the onset of a coronary heart disease event
