SEMINARI 2024
Interpretable natural language processing with cognitive networks: From Reddit posts to suicide notes
Dr. Massimo Stella
Università di Trento
14 Ottobre 2024, ore 10.00 Sala Seminari Informatica-C192
Texts convey knowledge in terms of words, symbols and relationships between them. Whereas word embeddings have revilutionised the field of Natural Language Processing, they pose some challenges for interpretation. This seminar introduces and reviews a different approach powered by cognitive networks, i.e. models of associative knowledge conveyed also through texts. Relying on powerful psychological and cognitive theories like frame semantics or the deep lexical hypothesis, cognitive networks can extract interpretable highlights across a variety of texts. The seminar will review pros and limitations of this approach in recent works about online perceptions of the gender gap, rape narratives on Reddit, emotional interviews of teenagers with clinical disorders and genuine suicide notes. Emphasis will be given to a complex-system perspective of this approach and its human-in-the-loop repercussions in artificial intelligence.

The knowledge from inside
Dr. Davide Remotti
Dipartimento di Scienze e Innovazione Tecnologica (DiSIT)
15 Luglio 2024, ore 11.00 AULA 207
An overview on the development of a novel imaging molecule seen from the inside of a pharmaceuticals company. Which competencies are strategic for a pharmaceutical company? How are these competencies deployed in a new drug entity development? chemistry (organic, inorganic, analytical, physico-chemical), biology, pharmacology, toxicology etc… a teamwork that allows to start from the idea to the market. Scientific development pathway is parallelized to regulatory and sustainability aspects. The final goal is to improve the diagnostic performances and, finally, to improve patients’ quality of life.
Nuclear Medicine, Diagnostic Imaging and Radiotherapy
Dr. Jonathan Martinelli
Dipartimento di Scienze e Innovazione Tecnologica (DiSIT)
15 Luglio 2024, ore 10.00 AULA 207
Nuclear Medicine is a multidisciplinary area where the treatment of patients is only the tip of the iceberg. Several steps are involved, starting from the investigation on possible targets, in silico modelling, design of suitable vectors, synthesis of “cold” precursors, radiolabelling with appropriate isotopic tracers, in vitro and in vivo studies, up to the final application to clinical trials and for the routine diagnosis and therapy. High technology and state-of-the-art equipment are also essential. It is a fascinating research and clinical field where physicists, chemists, biologists, pharmacists and doctors cooperate.
Holomorphic structures in noncommutative geometry/
Coloured combinatorial maps and quartic bi-tracial 2-matrix ensembles from noncommutative geometry
I & II
Prof. Masoud Khalkhali
University Western Ontario, Canada
04 Luglio 2024, ore 14.30 AULA 303
This talk will be a survey of what is known and what is still unknown in understanding holomophic structures in NCG with a focus on the noncommutative two sphere.
09 Luglio 2024, ore 14.30 AULA 303
11 Luglio 2024, ore 14.30 AULA 303
We present a closed-form recursive solution for the moments of three convergent quartic bi-tracial 2-matrix ensembles in the large N limit. These ensembles are toy models for Euclidean quantum gravity originally proposed by John Barrett and collaborators. A perturbative solution is first found using the noncommutative Schwinger-Dyson equations and properties of certain bi-colored unstable maps associated to the model. We then apply a result of Guionnet et al. to show that the perturbative and convergent solution coincide for a small neighbourhood of the coupling constants. For each model we compute an explicit expression for the free energy, critical points, and critical exponents in the large N limit. In particular, the string susceptibility is found to be γ=1/2 hinting that the associated universality class of the model is the continuous random tree. Joint work with Nathan Pagliaroli (Reference: Journal of High Energy Physics 2024 (5), 1-28).
Torsion and Lorentz symmetry from twisted spectral triples
Prof. Pierre Martinetti
Università di Genova
09 Luglio 2024, ore 11.30 AULA 303
Connes’ theory of spectral triples provides an extension of «geometry» beyond the riemannian setting, to the noncommutative framework.
The generalization to the pseudo-riemannian case (i.e lorentzian signature) is far from obvious. In this talk we will see how to generate « some » lorentzian structure by twisting the spectral triple of a riemannian closed manifold of dimension 4, through an orthogonal and geodesic preserving torsion.
Exploring the Biodiversity of Marine Invertebrates from the Shallow to Deep
Jose Lopez, PhD
Halmos College of Arts and Sciences. Northwestern University of Florida, USA
26 Giugno 2024, ore 16.00 AULA MAGNA con trasmissione dal vivo sulla Piattaforma Zoom
This talk will describe marine biodiversity linked not only by their shared habitat connected by seawater but also by their reliance on symbiosis, which is the coexistence of more than one organism in a single entity. Coral reefs provide an excellent showcase for symbiotic interactions, represent only a small percentage of total ocean area and yet holds a vast majority of biodiversity. Biologically built reefs depend on the patient and steady accretion via invertebrate lifestyles. In contrast, the deep ocean pelagic realms represent the largest habitats on the planet, have barely been investigated and thus will also likely yield large caches of biodiversity. Prof. Jose Lopez’s research picks up on several of these points, using modern molecular “-omics” methods. He has applied molecular genomics to characterize diverse marine systems: sibling species boundaries in keystone corals (Orbicella) and symbiotic communities in sponges, other invertebrates and anglerfish. The value and efficacy of applying genomics techniques to characterize marine biodiversity can be exemplified in the current Aquatic Symbiosis Genome project accessible at the following link:

Genomics and Biodiversity tales: a decade of comparative genomics research on Brazilian wildlifeg
Prof. Francisco Prosdocimi
Universidade Federal do Rio de Janeiro, RJ, Brazil
04 Giugno 2024, ore 16.00 AULA 204 con trasmissione dal vivo sulla Piattaforma Zoom
Durante la conferenza, il professor Francisco illustrerà i 13 anni di ricerche innovative condotte presso il "Laboratorio di Genomica e Biodiversità" dell'Università Federale di Rio de Janeiro. La sua presentazione sarà incentrata sull'affascinante biodiversità molecolare presente in uno dei Paesi con la maggiore biodiversità al mondo: Brasile. Il professor Francisco e il suo gruppo di ricerca hanno dedicato i loro sforzi a svelare gli intricati genomi di vari organismi della fauna e della flora brasiliana. Utilizzando tecniche all'avanguardia nel sequenziamento dei genomi, i ricercatori hanno sequenziato con successo diversi genomi mitocondriali di animali e piante, insieme a nuovi strumenti bioinformatici sviluppati per svelare le loro sequenze e fornire informazioni evolutive. Questi risultati hanno migliorato la nostra comprensione della biologia evolutiva di cladi animali e vegetali distinti, unici in Brasile e nelle Americhe. Utilizzando metodi innovativi di inferenza ancestrale, hanno fatto luce sulle origini delle tartarughe nel Giurassico, strettamente legate all'epoca della scissione di Pangea. Inoltre, l'utilizzo di approcci ddRNA-seq ha permesso di osservare l'affascinante evoluzione di nuovi meccanismi di impollinazione nelle bromeliacee. Attraverso un'analisi approfondita dei genomi dei pappagalli, il team di ricerca ha scoperto nuovi geni associati alla longevità e alla cognizione. Inoltre, il loro lavoro sulla filogenomica degli uccelli ha contribuito a far progredire la nostra comprensione dell'albero evolutivo completo degli uccelli. Attualmente, il suo team sta per completare l'analisi completa dell'intero genoma della "Banisteriopsis caapi" e della "Psychotria viridis", due piante maestre utilizzate nella preparazione della “ayahuasca", un infuso psichedelico ed enteogeno radicato nelle tradizioni amerindie. Sfruttando i long reads del sequenziamento PAC-BIO, questi ricercatori brasiliani stanno spingendo i confini della ricerca genomica, fornendo cromosomi completi per questi esemplari particolari, da telomero a telomero (T2T). Questa conferenza promette di essere un viaggio attraverso le recenti scoperte e conquiste nel campo della genomica, della biodiversità e della biomedicina.

Symmetries of fundamental equations of quantum mechanics/Integrable systems with position dependent mass I &II/Integrable systems with position dependent mass III &IV
Prof. Anatoly Nikitin (National Academy of Sciences, Kyiv and visiting professor DiSIT, UPO)
22 Maggio 2024, ore 11.00 AULA 303
Higher symmetries of quantum mechanical systems with position dependent mass (PDM) will be discussed. Such systems are important objects of modern physics. They are applied for modeling of condensed-matter systems, namely, semiconductors, quantum liquids and metal clusters, quantum wells, wires and dots and many, many others. We will start discussing quantum mechanical PDM systems admitting second order integrals of motion. Such systems including two spatial variables are well studied, but the much more interesting 3d systems were classified only partially.
22 Maggio 2024, ore 16.00 AULA 303
We will continue the study of quantum mechanical systems wiht position dependent mass (PDM) and present the last achievements in the classification of 3d PDM systems admitting first and second order integrals of motion. The classical Lie symmetries of such systems will be represented also.
Using the Causal Topology ofTemporal Networks in MachineLearning Tasks
Dr. Vincenzo Perri
Dipartimento di Scienze e Innovazione Tecnologica (DiSIT)

From the brain to the climate, complex systems constitute a real challenge for scientists and mathematicians as they are giving rise to dynamical phenomena notoriously difficult to understand, model and predict.
In the last twenty years the scientific community has made unprecedented progress in unveiling the structure of complex systems encoded in their network skeleton describing the set of their pairwise interactions. However networks are not able to characterize the ubiquitous higher-order interactions between more than two nodes that give rise to the complex systems topology captured by higher-order networks and simplicial complexes.
Here we reveal how non-linear dynamical processes can be used to learn the topology, by defining Topological Kuramoto model and Topological global synchronization. These critical phenomena capture the synchronization of topological signals, i.e. dynamical signal defined not only on nodes but also on links, triangles and higher-dimensional simplices in simplicial complexes. Moreover will discuss how the Dirac operator can be used to couple and process topological signal of different dimensions, formulating Dirac signal processing. Finally we will reveal how non-linear dynamics can shape topology by formulating triadic percolation. In triadic percolation triadic interactions can turn percolation into a fully-fledged dynamical process in which nodes can turn on and off intermittently in a periodic fashion or even chaotically leading to period doubling and a route to chaos of the percolation order parameter. Triadic percolation changes drastically our understanding of percolation and can describe real systems in which the giant component varies significantly in time such as in brain functional networks and in climate.
Workshop GIDRM DAY – Exploring diagnostic probes and procedures beyond Gd(III) for MRI applications
Comitato organizzatore composto da:
Prof. Mauro Botta, Prof. Giovanni B. Giovenzana, Dott. Claudio Cassino, Dott. Alessandro Nucera, Dott. Marco Ricci, Dott. Lorenzo Risolo, Dott. Fabio Travagin, Dott.ssa Maria Ludovica Macchia, Dott. Federico Forgione (UNIUPO-DiSIT / DSF)
31 Maggio 2024, ore 9.15 AULA 101-102
Recently, the use of Gd3+ chelates as contrast agents (CAs) in MRI has encountered two significant challenges. The first arose, ca. 20 years ago, with the occurrence of nephrogenic systemic fibrosis (NSF) in patients with renal impairment who had undergone contrast-enhanced MRIs, prompting safety concerns regarding Gd3+ chelates. While regulations restricting CA use in renally compromised patients have mitigated NSF cases, apprehensions regarding safety persist. Additionally, the environmental impact of CAs in MRI is becoming evident. Gd3+, typically sequestered in the lithosphere, is now detectable at elevated levels in drinking water sources and marine ecosystems. Addressing these challenges is imperative. This workshop aims to explore potential alternatives and discuss future directions.

Redundancy in the Structure and Dynamics of Complex Networks
Prof. Luis Rocha (Binghamton University, State University of New York)
27 Novembre 2023, ore 11.00 AULA 205
Many advances in network science derive from the study of patterns of connectivity (network structure), which provides many insights into the organization of complex systems. Yet, a critical gap remains in understanding how the structure of networks affects the dynamics of complex systems. We have been addressing this gap from a complementary angle: in addition to patterns of connectivity and patterns of dynamics, there are important patterns of redundancy which dictate how interaction structure and logic shape network dynamics.
We first characterize structural redundancy via the concept of distance backbone of a weighted graph: the sub-graph formed by all edges that obey a generalized triangle inequality for a given path length measure. We show that distance backbones are a parameter-free, principled method to obtain typically very small subgraphs that preserve all shortest paths and connectivity of the original networks across domains---and also preserve the modular and hierarchical structure of shortest distances. We illustrate the relationship to dynamics on networks by showing that the metric backbone is a primary subgraph for epidemic transmission based on pure diffusion processes. We further show that the (semi-triangular) edges that break the triangle inequality have highly variable importance in spreading dynamics. While all of them have null edge betweenness, a measure of how much they break the triangle inequality, the semi-triangular distortion, is highly correlated with edge relevance for spreading dynamics. Additionally, we discuss recent extensions to directed and multilayer graphs.
Finally, we summarize the distinct concept dynamical redundancy in (discrete dynamical systems) models of biochemical regulation and signaling. We show that the redundancy found in biological models is much more pronounced than what is expected from random networks, and a major reason for them being much more ordered than what the current criticality hypothesis, or “edge-of-chaos” theory, predicts.

Cross-kingdom chips: from microbes to humans to model pathophysiologic conditions
Dr. Giuseppe Cappellano
Department of Health Sciences DISS-UPO
26 Settembre 2023, ore 14.30 AULA 101
Micro- and nano-scaled devices have revolutionized the area of diagnostics, drug testing, analytical methods, chemical sensing, among others. Progress in microfluidic fabrication technology have led to the establishment of a chip environment as a versatile platform to model pathophysiologic conditions. The greatest advantage of microfluidics is the creation of a controlled microenvironment that precisely drives and controls the microfluidic flow in microchannels, improving detection sensitivity. Recently, microfluidic chips have been successfully developed for several organisms, including microbes, plants and human organs. For example, microbes-on-chip allows for the systematic study of chemical and biological interactions within a microbial community, as well as bacteria mobility and motility, quorum sensing or antibiotic resistance. Plant-on-chip fluidic platforms permits the monitoring of root growth and development, as well as root-pathogen interactions. Finally, human organ-on-chip reproduces in vitro the physiological environment of a whole living organ representing a powerful tool for drug screening, including applications to organ/disease modelling and personalized medicine. The implementation of artificial intelligence in these systems makes them more advanced, thereby helping to provide a more accurate diagnosis. These miniatured chips would help understand complex molecular networks, by determining how individual parts are integrated in time and space to form complex, dynamic cellular functions, and how cellular interactions create higher-order functions.
Aerogels: synthesis, characterization and applications
Prof. Attila Forgács
Università di Debrecen, Facoltà di Scienze e Tecnologie, Istituto di Chimica, Dipartimento di Chimica Inorganica e Analitica (Ungheria)
20 Luglio 2023, ore 10.00 AULA 303
The term aerogel is used to describe a family of open porous solids that can be fabricated from a wide variety of basematerials e.g. inorganic oxides, carbon, biopolymers, synthetic polymers. Aerogels are highly porous and consist of an open-cell pore network. Their main characteristics are high specific surface area (500–1200 m2 g-1), high porosity (80–99.8%), low density (~0.003–0.5 g cm-3), low thermal conductivity (0.005–0.1 W/mK), ultra-low dielectric constant (k = 1.0–2.0) and low refraction index (~1.05). Relying on these characteristics, the main research directions for the applications of aerogels are as follows: i) thermal and electrical insulation for industrial applications; ii) high performance adsorbents for gas separation and for environmental remediation; iii) catalysts and catalyst supports; iv) drug delivery systems, and scaffolds for tissue engineering and regenerative medicine. For these reasons, aerogels are currently one of the most extensively researched porous materials.
Polymer and hybrid nanostructures for sustainable photonics
Prof. Davide Comoretto
Dipartimento di Chimica e Chimica Industriale, Università di Genova
14 Luglio 2023, ore 15.00 AULA 204
Year by year, the importance of organic and hybrid highly ordered nanostructures in photonics is increasing. Polymers - even recycled or from renewable sources - represent an interesting alternative to more traditional metal oxides, being easily processable and allowing for light, free-standing and flexible structures able to address several sustainable development goals of the ONU 2030 agenda. In sensing, they allow for the preparation of label-free sensors for food degradation by products or for environmental monitoring. In the thermal shielding field, they would allow for thin, transparent films able to reduce heating by sunlight and to improve the sustainability of buildings or to keep the quality of foods/beverages. Mechanochromic photonic systems allow an easy read-out chromatic response to mechanical stimuli. Moreover, in fluorescence control and lasing, photonic crystals are fundamental towards all-organic photonics and polymer quantum electrodynamics providing fundamental hints to quantum technologies and polymer metamaterials. Finally, hybrid materials are of great interest in these regards as they combine the processability of polymers with the superior refractive index properties of inorganics.
Contribution of concrete to carbon neutrality
Prof. Takafumi NOGUCHI (https://moonshot-c4s.jp/en)
University of Tokyo - Department of Architecture
05 Luglio 2023, ore 14.00 AULA 104
Concrete is an indispensable construction material for social capital development, but around 8% of total CO2 emitted annually worldwide comes from cement production. To establish a carbon neutral society by 2050, 55 billion tons of CO2 in the atmosphere which have been emitted due to calcination of limestone during cement production and Ca which has been remained in the concrete should be combined again to form a carbon neutral circulation. Consequently, global warming will be greatly suppressed, and the global environment will be regenerated by concrete, “White Carbon”.

Presentazione Master "Data Management e Coordinamento delle Sperimentazioni Cliniche"
Dott.ssa Marta Betti (Dipartimento Attività Integrate Ricerca Innovazione, DAIRI - Azienda Ospedaliera di Alessandria)
31 Maggio 2023, ore 14.00 AULA 101
Master di primo livello organizzato dall'Università del Piemonte Orientale in collaborazione con l’Azienda Ospedaliera “SS Antonio e Biagio e Cesare Arrigo”, Dipartimento Attività Integrate Ricerca Innovazione (Alessandria) che prevede una durata annuale. L’obiettivo del Master è l’acquisizione delle conoscenze e competenze necessarie alla pianificazione e conduzione di sperimentazioni cliniche, alla raccolta dei dati, all’analisi statistica e alla presentazione dei risultati. In particolare, l’obiettivo è quello di integrare l’attività didattica frontale con insegnamenti molto pratici, grazie alle numerose esercitazioni previste.
Il Master fornisce conoscenze e competenze per Data Manager/Clinical Study Coordinator, Clinical Research Associate (CRA) e Infermieri di Ricerca. Il Data Manager/Clinical Study Coordinator è quella figura che si occupa non solo dei dati clinici, dalla fase di trasferimento dalla cartella clinica alle schede di raccolta dati (CRF) a quella del processo di cleaning fino al conclusivo trasferimento ai centri statistici, garantendone accuratezza e verificabilità, ma soprattutto è colui che svolge un ruolo di coordinamento dei vari aspetti della sperimentazione, e costituisce il riferimento sia per l'equipe clinica che per i comitati etici e le autorità regolatorie. Il Clinical Research Associate provvede al monitoraggio delle sperimentazioni cliniche, in accordo con le norme di Good Clinical Practice, verificandone la corretta applicazione dei relativi criteri di qualità. L’Infermiere di Ricerca opera con un elevato grado di coinvolgimento nel contesto della ricerca sanitaria, erogando attività infermieristiche di supporto alle sperimentazioni cliniche. Il fabbisogno delle suddette figure professionali, che tramite il Master si specializzano, si può ritenere in leggero aumento, data la richiesta di questi esperti sia nel settore pubblico sia nel settore privato. La terza edizione del Master si prevede che prenderà avvio nei primi mesi del 2024, con pubblicazione del bando nell'autunno 2023.

On the Efficient Bounding of Counterfactual Queries
Alessandro Antonucci
IDSIA, Lugano, Svizzera
19 Aprile 2023, ore 10.00 SALA SEMINARI INFORMATICA (C192) con trasmissione dal vivo sul canale Youtube UPO del Prof. Luigi Portinale
Structural causal models are the fundamental modeling unit in Pearl’s theory of causality.
In principle they allow to solve counterfactuals, which are at the top rung of the ladder of causation. In practice they often contain latent variables, this limiting their application to special settings.
We notice how observations of the manifest variables induce constraints on the probabilities of the latent ones. This allows to map a causal model into a credal network. Causal inferences, such as those based on interventions and counterfactuals, can consequently be obtained by inference algorithms for credal networks. These return sharp values in the identifiable case, while intervals corresponding to the exact bounds are produced in the unidentifiable case.
To bypass the computational hurdles imposed by credal network inference in the general case, we then derive an EM scheme that allows to address inference via standard algorithms for Bayesian networks.
The result is a general method to compute counterfactuals, be they identifiable or not (in which case we deliver an inner approximation of the bounds). We also provide credible intervals proving that the EM approximation becomes accurate in a fair number of runs. We finally discuss an empirical validation on a synthetic benchmark, a case study on palliative care and some recent extensions to cope with hybrid and/or biased data.
Analisi sistematica delle similitudini tra progressione tumorale e sviluppo embrionale e la sua applicazione clinica tramite intelligenza artificiale
Dr. Enrico Moiso
Massachusetts Institute of Technology, Cambridge, MA
03 Aprile 2023, ore 15.00 AULA 102
Cancer is partly a developmental disease, with malignancies named based on cell or tissue of origin. However, a systematic atlas of tumor origins is lacking. Here we map the single-cell organogenesis of 56 developmental trajectories to the transcriptomes of over 10,000 tumors across 33 cancer types. We deconvolute tumor transcriptomes into signals for individual developmental trajectories. Using these signals as inputs, we construct a developmental multilayer perceptron (D-MLP) classifier that outputs cancer origin. D-MLP (ROC-AUC: 0.974 for top prediction) outperforms benchmark classifiers. We analyze tumors from patients with cancer of unknown primary (CUP), selecting the most difficult cases in which extensive multimodal workup yielded no definitive tumor type. Interestingly, CUPs form groups distinguished by developmental trajectories, and classification reveals diagnosis for patient tumors. Our results provide an atlas of tumor developmental origins, provide a tool for diagnostic pathology, and suggest developmental classification may be a useful approach for patient tumors.

La grave siccità che sta colpendo l’Italia e, in particolare, la Regione Piemonte costringe tutti gli attori coinvolti a una seria riflessione sulle modalità disponibili per affrontare il cambiamento climatico in corso. La scarsità d’acqua impone che vengano individuate strade alternative per compensarla e superarla: il necessario ammodernamento delle strutture, compiuto in un’ottica di investimenti cospicui e strategici, non può prescindere da un ripensamento del modello economico e produttivo. Il diritto all’acqua, come sancito all’interno dell’Obiettivo n. 6 dell’Agenda Onu 2030 per lo Sviluppo Sostenibile, è universale e, in quanto tale, va tutelato attraverso l’adattamento climatico: risparmiare la risorsa idrica e allo stesso tempo trovare modalità innovative per riutilizzarla in una visione circolare e di lungo periodo.

As part of the annual meeting of the H2020-project SCENARIOS, the "First International Workshop on PFAS Transport and PFAS Toxicology" will feature high-level speakers and experts PFAS is the acronym for per- and polyfluoroalkyl substances and represents a group of emerging contaminants known for their persistence and mobility in the environment. This is a hotly debated topic these days. Chemicals such as PFOA and PFOS are ubiquitous pollutants found in all environmental matrices and in biota where they readily accumulate. The Po River basin, Italy's largest river, has been subject to constant and continuous contamination with such chemicals. Even though these Legacy PFAS have been restricted since 2014 under the Stockholm Convention, their traces are still present today. The Trissino disaster in the province of Vicenza, Italy, resulted in the contamination of one of the largest underground aquifers in Europe. A large number of citizens of all ages were exposed to PFAS and will therefore forever carry traces of these substances in their blood. These substances are also of concern to supranational organizations, which are called upon to regulate their use and release. The European Chemicals Agency (ECHA) is due to rule in the next three months whether to ban short carbon chain PFAS, known as alternative PFAS, in firefighting foams. In addition, a public consultation for a full restriction of the entire class of compounds under the European regulation REACH will begin in January 2023 after five EU member states made the proposal. Today's workshop is the first in a series of workshops designed within the SCENARIOS project to contribute to a better understanding of the effects of PFASs on human health and the environment so that decision makers can make informed and fair decisions about the regulation of these substances.

Biopolymer membranes obtained by electrospinning process
Prof.ssa Silvia Vicini (Department of Chemistry and Industrial Chemistry, University of Genoa)
18 Novembre 2022, ore 14.00 AULA 205
Over the last years electrospinning technique has emerged as an easy, fast and affordable approach to prepare nanofibrous membranes with a micro-structure which strongly resemble the extra-cellular matrix.
Electrospinning is based on the application of a strong potential difference to create an electrically charged polymer solution jet which leads to the formation of nano and/or microfibres subsequently collected on a proper surface; thus, highly porous mats with a high specific surface area can be easily obtained and, above all, they were found able to promote human cell viability.
Alginate and chitosan-based membranes are prepared via electrospinning using solution and poly(ethylene oxide) as co-spinning agent. Different solutions are rheologically characterized in order to assess the viscosity values suitable to proceed with the electrospinning process.
The membranes are coagulated to stabilize them using different baths. Moreover, a crosslinking approach are optimized to obtain insoluble mats whose composition is investigated, proving the elimination of the co- spinning agent. Mechanical characterization is performed to test the stress/strain behaviour.
Three Critical Issues on Working with Mobile Phone Data During a Pandemic
Dr. Leo Ferres (Universidad del Desarrollo, Santiago de Chile)
27 Ottobre 2022, ore 10.00 Diretta Meet
During the COVID-19 pandemic, mobile phone data sets have been used all over the world to measure the effectiveness of mobility restrictions and to inform epidemiological models of disease dynamics. However, there are several issues with mobile phone datasets that have not been thoroughly investigated, and which can cause serious impacts in the conclusions drawn from the studies using these data, and their implementation or impact in public policy, for example. Here we discuss three of these issues: Modifiable area units (MEAP) and the politics of administrative boundaries, common evaluation techniques of trip/mobility algorithms, and the ethics/responsibility of data sharing. Some of these issues have straightforward methodologies (even if not solutions per se, such as the MEAP), others have straightforward solutions, but haven’t been discussed yet (trip evaluations), and others are downright difficult to reach a common ground, such as the sharing of private, sensitive, commercial data. In this work, we discuss a few solutions to each of these issues, and open the door for a more open scientific discussion.
UnderstandingLarge-scale Smartphone Usage
Dott.ssa Anna Sapienza (Copenhagen Center for Social Data Science - SODAS)
20 Ottobre 2022, ore 10.00 AULA 203
Recent years have seen an explosive growth in the use of mobile apps on smartphones and tablets. With over 2.7 billion smartphone users across the world checking their phones over 80 times a day, smartphone data offer a unique opportunity to understand main aspects of human behaviors, e.g., mobility, sleep patterns, and mobile app usage. Despite the impact that smartphones have in shaping our society, there is surprisingly little general knowledge about what has changed and what goes on when people stare at their screen. In this talk, I will present the differences in smartphone use across users, based on the study of an unprecedented dataset, including mobile app traces of thousands of users in time. I will show how users interact with smartphones with the aim of characterizing users with high/low levels of engagement, the type of apps underlying this engagement, and the effects of external factors, such as user demographics and the environment.
Low field TD-NMR for the study of polymeric networks
Prof. Roberto Simonutti (Department of Materials Science - University of Milan-Bicocca)
23 Settembre 2022, ore 11.00 AULA 203
Polymer networks, including rubbers and hydrogels, are ubiquitous materials. The determination of their structure-property relationship is fundamental for their rational improvement.
Low Field (LF) Time Domain (TD) Nuclear Magnetic Resonance (NMR) is a powerful technique to probe molecular-level dynamics, through 1H relaxation times T1 e T2. and the measure of residual dipolar couplings (Dres), which are linearly proportional to crosslinks density (CLD).1
This technique has been exploited to measure the evolution of crosslinking in conventional rubbers and their blends,2 and to prove the formation of polar crosslinks clusters in more innovative modified EPDM rubbers crosslinked via reversible Diels-Alder chemistry3. Figure 1 (right) highlights the bimodal distribution of Dres in a heterogeneous system as compared to a more homogeneous one. Access to CLD distribution is the most outstanding advantage of TD-NMR compared to traditional method for the determination of CLD, such as equilibrium swelling measurements.
Important variations in chain dynamics, such as phase transitions, can be easily monitored with the study of T2 at varying temperatures. In Figure 1, a methylated cellulose thermogelating material4 shows increased T2 upon temperature increase, followed by a sudden drop at the gelation point. The reversibility of the process, the formation of a metastable phase and the associated hysteresis phenomena can be monitored, obtaining results in line with rheological testing.
These examples highlight that LF TD-NMR is a comprehensive tool to characterize in details polymeric networks, making it suitable for both academic and industrial applications.

Lignin valorization towards a sustainable future
Dott.ssa Alice Boarino (Institut des Matériaux and Institut des Sciences et Ingénierie Chimiques, Laboratoire des Polymères, École Polytechnique Fédérale de Lausanne (EPFL), Lausanne, Switzerland)
23 Maggio 2022, ore 14.00 AULA 203
Lignin is one of the main components of biomass, discarded a by-product of the paper industry in huge quantities every year. The complex structure of lignin, composed of aromatic rings with hydroxy and methoxy functional groups, provides interesting properties such as antioxidant, UV-barrier and antimicrobial activity. Due to the high availability, biodegradability and biocompatibility of this plant-derived polymer, significant attention has been given to a wide-scale use of lignin-derived products in various applications. In this seminar, the valorisation of this under-exploited material into high added-value applications will be discussed.

Building Thinking Classrooms
Prof. Peter Liljedahl (Simon Fraser University, Vancouver, Canada)
15 Marzo 2022, ore 15.00 Diretta Zoom
Much of how classrooms look and much of what happens in them today is guided by institutional norms laid down at the inception of an industrial-age model of public education. These norms have enabled a culture of teaching and learning that is often devoid of student thinking. In this session I present some of the results of over 15 years of research into how teachers can transform their classrooms from a space where students mimic to where students think. The practices discussed will intertwine with, and make extensive references to, the recently published book, Building Thinking Classrooms in Mathematics (Grades K-12): 14 Teaching Practices for Enhancing Learning.
Che cosa ha l'intelligenza artificiale in comune con la filosofia? (McCarthy 1995)
Prof.ssa Margherita Benzi (UNIUPO-DiGSPES)
07 Febbraio 2022, ore 16.00 AULA 102
Come suggerisce il titolo, "prestato" da uno dei padri dell'IA, la filosofia ha svolto un ruolo importante in intelligenza artificiale. Altrettanto importante, anche se fino a tempi recenti meno riconosciuta, è stato il contributo dell’IA alla riflessione su alcune tematiche centrali della filosofia come la causalità e il rapporto mente-cervello. La relazione tra filosofia e IA è però anche complicata, con intersezioni, illusioni reciproche e malintesi. Questo seminario intende ripercorre la storia di alcuni aspetti di tale relazione, e mostrerà come alcuni degli attuali problemi filosofici dell’IA possano avere conseguenze molto pratiche nella nostra vita.
Numerical methods with equation-dependent coefficients for stiff differential problems
Dott. Giovanni Pagano (Department of Mathematics, University of Salerno)
02 Febbraio 2022, ore 16.00 AULA 203
We show techniques that allow to improve the accuracy and/or stability properties of classical explicit numerical schemes solving ordinary differential equations systems.
These techniques foresee, with different motivations, the modification of the classical methods coefficients, which become matrices dependent on the Jacobian of the problem. Obviously, the new Jacobian-dependent schemes thus derived can also be used for the solution of partial differential equations systems through the method of lines, then solving the semi-discretized in space problem.
In detail, we analyze the application of the mentioned methodologies on explicit Runge-Kutta methods and peer methods, proving that it is possible to make them A-stable, while preserving their explicit structure. Since the inversion of Jacobian-dependent matrices is required at each step, it is not possible to classify the new schemes as totally explicit methods. However, for some problems these methods are actually explicit, as the Jacobian is either constant, or it can be approximated with a constant matrix. Numerical tests highlight the advantages of the new methods.
Polycarbonates from Carbon Dioxide and Epoxides: synthesis, properties, and potential applications
Dott.ssa Simona Losio e Dott.ssa Laura Boggioni (SCITEC CNR, Milano)
17 Gennaio 2022, ore 11.00 AULA 204
Polycarbonates can be prepared by the copolymerization of epoxides with carbon dioxide (CO2) as an inexpensive, abundant, nontoxic, and renewable feedstock. Since the discovery of Inoue in 1969, the copolymerization of epoxides and CO2 has become an important and useful technology for the large-scale utilization of CO2 in chemical synthesis, employing mainly propylene oxide and cyclohexene oxide. In recent years, the use of functional epoxide monomers has become an emerging topic with a broad scope of potential applications This presentation will cover the synthesis, the physico-chemical properties, and the growing applications of this class of green polymers.
