[DEWS Colloquia] A mathematical model of the G1/S transition for the budding yeast

Davide Di Ruscio Internal Seminars

Speaker: Prof. Pasquale Palumbo (University of Milano-Bicocca, Italy)

Title: A mathematical model of the G1/S transition for the budding yeast

Abstract: In budding yeast, overcoming of a critical size to enter S phase and the mitosis/mating switch—two central cell fate events—take place in the G1 phase of the cell cycle. Here we present a mathematical model of the basic molecular mechanism controlling the G1/S transition, whose major regulatory feature is multisite phosphorylation of nuclear Whi5. Cln3–Cdk1, whose nuclear amount is proportional to cell size, and then Cln1,2–Cdk1, randomly phosphorylate both decoy and functional Whi5 sites. Full phosphorylation of functional sites releases Whi5 inhibitory activity, activating G1/S transcription. Simulation analysis shows that this mechanism ensures coherent release of Whi5 inhibitory action and accounts for many experimentally observed properties of mitotically growing or conjugating G1 cells. Cell cycle progression and transcriptional analyses of a Whi5 phosphomimetic mutant verify the model prediction that coherent transcription of the G1/S regulon and ensuing G1/S transition requires full phosphorylation of Whi5 functional sites

[COURSE] Development of recommendation systems in software engineering: challenges and lessons learned

Davide Di Ruscio PhD Courses

Lecturer: Prof. Davide Di Ruscio

Abstract: Open-source software (OSS) forges contain rich data sources useful for supporting development activities. Several techniques and tools have been promoted to provide open-source developers with innovative features, aiming to obtain improvements in development effort, cost savings, and developer productivity. In the context of the EU H2020 CROSSMINER and TYPHON projects, different recommendation systems have been conceived to assist software programmers in different phases of the development process by providing them with various artifacts, such as third-party libraries, or documentation about how to use the APIs being adopted, or relevant API function calls. To develop such recommendations, various technical choices have been made to overcome issues related to several aspects, including the lack of baselines, limited data availability, decisions about the performance measures, and evaluation approaches. This lecture introduces Recommendation Systems in Software Engineering (RSSE) and describes the challenges that have been encountered in the context of the CROSSMINER and TYPHON projects. Specific attention is devoted to present the intricacies related to the development and evaluation techniques that have been employed to conceive and evaluate the CROSSMINER recommendation systems. The lessons that have been learned while working on the project are also discussed.

Neuro-symbolic Liveness Verification

Davide Di Ruscio External Seminars

Speaker: Dr. Mirco Giacobbe (University of Oxford, UK)

Title: Neuro-symbolic Liveness Verification

Abstract: Liveness verification answers the question of whether a system always responds with desirable behavior or, dually, never gets stuck without responding at all. For dynamical systems, this relates to the stability question; for computer programs, it relates to the halting problem. I will talk about a novel method for constructing liveness proofs by learning witnesses (Lyapunov and ranking functions) from data using neural networks combined with symbolic reasoning. I will talk about how we apply this neuro-symbolic approach to the stability analysis of dynamical systems, to the termination analysis of Java programs, and to the almost-sure termination analysis of probabilistic programs.

Course on “Thresholds for a SIR Model on One-Dimensional Small-World Networks”

Davide Di Ruscio External Seminars
Schedule: 11 May 2021, 14:00 GMT/16:00 Italian time

Virtual link: https://us02web.zoom.us/j/83390778311

Speaker: Andrea Clementi (Università di Roma “Tor Vergata”)

TITLE: Sharp Thresholds for a SIR Model on One-Dimensional Small-World Networks

ABSTRACT: After a short overview of the basic notions of the classic Susceptible-Infectious-Recovered (SIR) epidemic model in the fully-mixed scenario, we review some fundamental results of the discrete-time version of the SIR model, known as Reed-Frost model, in some simple network topologies. We then consider the the Reed-Frost model over “small-world” graphs, in which graphs are obtained by adding random edges to a cycle. In 3-regular graphs obtained as the union of a cycle and a random perfect matching, we show that there is a sharp threshold at 0.5 for the contagion probability along edges. In graphs obtained as the union of a cycle and of an Erdos-Renyi random graph with n nodes and edge probability c/n, we show that there is a sharp threshold p_c for the contagion probability: the value of p_c turns out to be about 0.41 for the sparse case c=1 yielding an expected node degree similar to the random 3-regular graphs above. In both models, below the threshold we prove that the infection only affects O(log n) nodes, and that above the threshold it affects Omega(n) nodes. These are the first fully rigorous results establishing a phase transition for SIR models (and equivalent percolation problems) in small-world graphs. Although one-dimensional small-world graphs are an idealized and unrealistic network model, a number of realistic qualitative phenomena emerge from our analysis, including the spread of the disease through a sequence of local outbreaks, the danger posed by random connections, and the effect of super-spreader events. This is a joint research with Luca Becchetti, Riccardo Denni, Francesco Pasquale, Luca Trevisan, and Isabella Ziccardi.

Davide Di Ruscio External Courses

Si terrà nel mese di maggio 2021 all’Università degli Studi dell’Aquila, all’interno del Dottorato di Ricerca in Ingegneria Industriale e dell’Informazione e di Economia, la II° edizione del corso “EURES: La mobilità una regola non più un’eccezione”, organizzato dal Servizio EURES della Regione Abruzzo in collaborazione con il Coordinamento Nazionale EURES-ANPAL.

Il corso è stato realizzato per la prima volta nel 2018, vedendo la partecipazione di allievi di diversi Corsi di Dottorato dell’Ateneo aquilano e riscuotendo un grande interesse da parte di tutti i partecipanti. L’iniziativa ha inoltre ottenuto diversi riconoscimenti a livello europeo, trattandosi del primo corso universitario che in Europa ha coinvolto la rete EURES . Il progetto è stato considerato una “best-practice”, non solo in termini di comunicazione e promozione della rete europea del lavoro, ma
anche di integrazione formale della stessa nei sistemi di istruzione e formazione accademica.

Obiettivo del corso, strutturato in 5 giornate e le cui lezioni si svolgeranno il 6-7, 13-14 e 21 maggio, è quello di fornire una adeguata conoscenza degli strumenti e opportunità in grado di favorire il trasferimento in un altro paese per motivi di studio, formazione o lavoro. Pertanto saranno trattati diversi argomenti inerenti il tema della mobilità transnazionale: la normativa, l’organizzazione e i servizi della Rete EURES, i progetti di mobilità europea e le misure di finanziamento, le opportunità di tirocinio e carriera nelle istituzioni e agenzie europee, l’acquisizione delle competenze trasversali, il riconoscimento delle qualifiche professionali e dei titoli di studio nell’Unione Europea, la sicurezza sociale, la tassazione e la legislazione connesse alla libera circolazione dei lavoratori nell’UE, gli aspetti principali del fenomeno migratorio italiano e del sistema di rappresentanza degli Italiani all’estero, nell’ottica di fornire agli studenti un quadro piuttosto completo del concetto di mobilità e degli elementi
pratici e strumenti concreti per approcciarsi ad esperienze di lavoro e formazione in ambito europeo.

Il corso vedrà la partecipazione di rappresentanti del Coordinamento
Nazionale EURES, della rete dei Consulenti EURES italiani e della Danimarca, Svezia, Irlanda, Olanda, Francia, Portogallo, Germania, oltre che di esperti dell’emigrazione e Responsabili nazionali di reti e programmi europei a supporto della mobilità, quali Europass, Euroguidance, EQF-Quadro europeo delle qualifiche professionali, Eurodesk, Euraxess,
Europe Direct, Erasmus Giovani Imprenditori, Erasmus+).
