description: Data-driven models based on deep learning algorithms intend to overcome the limitations of traditional constitutive modelling by directly learning from data. However, the need for extensive data that collate the full state of the material is hindered by traditional experimental observations, which typically provide only small data - sparse and partial material state observations. To address this issue, we develop a novel deep learning algorithm referred to as Neural Integration for Constitutive Equations to discover constitutive models at the material point level from scarce and incomplete observations. It builds upon the solution of the initial value problem describing the time evolution of the material state, unlike the majority of data-driven approaches for constitutive modelling that require large data of increments of state variables. Numerical benchmarks demonstrate that the method can learn accurate, consistent, and robust constitutive models from incomplete, sparse, and noisy data collecting simple conventional experimental protocols.
The Effect of Spacetime Curvature on Statistical Distributions

description: The Boltzmann distribution of an ideal gas is determined by the Hamiltonian function generating single particle dynamics. Systems with higher complexity often exhibit topological constraints, which are independent of the Hamiltonian and may affect the shape of the distribution function as well. Here, we study a further source of heterogeneity, the curvature of spacetime arising from the general theory of relativity. The present construction relies on three assumptions: first, the statistical ensemble is made of particles obeying geodesic equations, which define the phase space of the system. Next, the metric coefficients are time-symmetric, implying that, if thermodynamic equilibrium is achieved, all physical observables are independent of coordinate time. Finally, ergodicity is enforced with respect to proper time, so that ambiguity in the choice of a time variable for the statistical ensemble is removed. Under these hypothesis, we derive the distribution function of thermodynamic equilibrium, and verify that it reduces to the Boltzmann distribution in the classical limit. We further show that spacetime curvature affects physical observables, even far from the source of the metric. Two examples are analyzed: an ideal gas in Schwarzschild spacetime and a charged gas in Kerr-Newman spacetime. In the Schwarzschild case, conservation of macroscopic constraints, such as angular momentum, combined with relativistic distortion of the distribution function can produce configurations with decreasing density and growing azimuthal rotation velocity far from the event horizon of the central mass. In the Kerr-Newman case, it is found that kinetic energy associated with azimuthal rotations is an increasing function of the radial coordinate, and it eventually approaches a constant value corresponding to classical equipartition, even though spatial particle density decreases.

description: Li$_2$Sr[MnN]$_2$ single crystals were successfully grown out of Li rich flux. The crystal structure was determined by single crystal X-ray diffraction and revealed almost linear $-$N$-$Mn$-$N$-$Mn$-$ chains as central structural motif. Tetragonal columns of this air and moisture sensitive nitridomanganate were employed for electrical transport, heat capacity, and anisotropic magnetization measurements. Both the electronic and magnetic properties are most remarkable, in particular the linear increase of the magnetic susceptibility with temperature that is reminiscent of underdoped cuprate and Fe-based superconductors. Clear indications for antiferromagnetic ordering at $T_{\rm N} = 290$ K were obtained. Metallic transport behavior is experimentally observed in accordance with electronic band structure calculations.

description: We study the phenomenological viability of chiral extensions of the Standard Model, with new chiral fermions acquiring their mass through interactions with a single Higgs. We examine constraints from electroweak precision tests, Higgs physics and direct searches at the LHC. Our analysis indicates that purely chiral scenarios are perturbatively excluded by the combination of Higgs coupling measurements and LHC direct searches. However, allowing for a partial contribution from vector-like masses opens up the parameter space and non-decoupled exotic leptons could account for the observed 2$σ$ deviation in $h \to Zγ$. This scenario will be further tested in the high-luminosity phase of the LHC.

description: Cyber-attacks on Industrial Automation and Control Systems (IACS) are rising in numbers and sophistication. Embedded controller devices such as Programmable Logic Controllers (PLCs), which are central to controlling physical processes, must be secured against attacks on confidentiality, integrity and availability. The focus of this paper is to add design-level support for security in IACS applications, especially around inter-PLC communications. We propose an end-to-end solution to develop IACS applications with inherent, and parametric support for security. Built using the IEC 61499 Function Blocks standard, this solution allows us to annotate certain communications as 'secure' during design time. When the application is compiled, these annotations are transformed into a security layer that implements encrypted communication between PLCs. In this paper, we implement a part of this security layer focussed on confidentiality, called Confidentiality Layer for Function Blocks (CL4FB), which provides a range of encryption/decryption and secure key exchange functionalities. We study the impact of using CL4FB in IACS applications with real-time constraints. Through a case study focussing on protection functions in smart-grids, we show that varying levels of confidentiality can be achieved while also meeting hard real-time deadlines.

Finding unexplained activities in time-stamped observation data
Creators: name: Persia, Fabio
Publisher: name: Università degli Studi di Napoli Federico II
Year: 2013

description: The activity recognition is a very big challenge for the entire research community. Thus, there are already numerous techniques able to find occurrences of activities in time-stamped observation data (e.g., a video, a sequence of transactions at a website, etc.) with each occurrence having an associated probability.
However, all these techniques rely on models encoding a priori knowledge of either normal or malicious behavior. They cannot deal with events such as “zero day” attacks that have never been seen before. In practice, all these methods are incapable of quantifying how well available models explain a sequence of events observed in an observation stream.
By the way, the goal of this thesis is different: in order to address the issue listed above, we want to find the subsequences of the observation data, called unexplained sequences, that known models are not able to “explain” with a certain confidence.
Thus, we start with a known set A of activities (both innocuous and dangerous) that we wish to monitor and we wish to identify “unexplained” subsequences in an observation sequence that are poorly explained (e.g., because they may contain occurrences of activities that have never been seen or anticipated before, i.e. they are not in A).
We formally define the probability that a sequence of observations is unexplained (totally or partially) w.r.t. A. We develop efficient algorithms to identify the top-k Totally and Partially Unexplained Activities w.r.t. A. These algorithms leverage theorems that enable us to speed up the search for totally/partially unexplained activities. We describe experiments using real-world video and cyber security datasets showing that our approach works well in practice in terms of both running time and accuracy.

description: Relevance plays a central role in information retrieval (IR), which has received extensive studies starting from the 20th century. The definition and the modeling of relevance has always been critical challenges in both information science and computer science research areas. Along with the debate and exploration on relevance, IR has already become a core task in many real-world applications, such as Web search engines, question answering systems, conversational bots, and so on. While relevance acts as a unified concept in all these retrieval tasks, the inherent definitions are quite different due to the heterogeneity of these tasks. This raises a question to us: Do these different forms of relevance really lead to different modeling focuses? To answer this question, in this work, we conduct an empirical study on relevance modeling in three representative IR tasks, i.e., document retrieval, answer retrieval, and response retrieval. Specifically, we attempt to study the following two questions: 1) Does relevance modeling in these tasks really show differences in terms of natural language understanding (NLU)? We employ 16 linguistic tasks to probe a unified retrieval model over these three retrieval tasks to answer this question. 2) If there do exist differences, how can we leverage the findings to enhance the relevance modeling? We proposed three intervention methods to investigate how to leverage different modeling focuses of relevance to improve these IR tasks. We believe the way we study the problem as well as our findings would be beneficial to the IR community.

description: The electronic and magnetic properties of the mother material LaOFeAs of new superconductors have been carefully studied using first-principles electronic structure calculations based on the generalized gradient approximation in the density functional theory. The present calculation predicts that the ground state of LaOFeAs is antiferromagnetic with a stripe type magnetic moment alignment leading to orthorhombic symmetry of the crystal. In this particular magnetic state, the density of states at the Fermi level is very small. On the other hand, LaOFeP has turned out to be paramagnetic and a good metal. Implications of the results regarding the experimental observations will also be presented.

description: The formation of a cool disk in the innermost regions of black hole X-ray transient systems in the low hard state is investigated. Taking into account the combined cooling associated with the Compton and conductive energy transport processes in a corona, the radial structure of a disk is described for a range of mass accretion rates. The mass flow in an optically thick inner region can be maintained by the condensation of matter from a corona with the disk temperature and luminosity varying continuously as a function of the accretion rate. Although such a disk component can be present, the contribution of the optically thick disk component to the total luminosity can be small since the mass flow due to condensation in the optically thick disk underlying the corona can be significantly less than the mass flow rate in the corona. The model is applied to the observations of the low quiescent state of the black hole source GX 339-4 at luminosities of around $0.01 L_{Edd}$ and is able to explain the temperature of the thermal component at the observed luminosities. Since conductive cooling dominates Compton cooling at low mass accretion rates, the luminosity corresponding to the critical mass accretion rate above which a weak thermal disk component can be present in the low hard state is estimated to be as low as $0.001 L_{Edd}$.

description: Between the end of the 50’s and the first half of the 60’s, three experts
filmmakers, Fernando Cerchio, Giuseppe Ferrara and Gilbert Bovay,
produced three documentaries on Gela.The three works, especially
the first two, were required by ENI and were framed in a wider communication strategy aimed at promoting national and international business development in this historical moment - to relate the progressive
construction of a petrochemical plant in the Sicilian city after the drilling phase in the surrounding sea. A modern petrochemical plant, according
to the intentions of ENI, should serve as an engine for economic
and social development of the area. The three documentaries, through
analysis of the archive sources which were used during the production
process, are able to construct (conform a large number of the
results of the industrial cinema) a pannel of witnesses, which help us
revising some crucial characters - both negative and positive - which
have been determined in the course of these years of progressive transformation of our country in terms of geography, and economic and industrial development.

Au cours de la période qui va de la fin des années 50 à la première
moitié des années 60, trois metteurs en scène, Fernando Cerchio, Giuseppe Ferrara et Gilbert Bovay, ont réalisé trois documentaires sur Gela.
Il s’agit de trois oeuvres qui, surtout les deux premières, étaient fortement
voulues par l’ENI et qui faisaient partie d’une plus ample stratégie
de communication visant à valoriser le caractère national et international
du développement d’entreprise de cette époque-là. Par ailleurs,
cela servait à raconter la construction progressive de l’usine pétrochimique
de la ville sicilienne, après la phase de forage dans la mer environnante.
Il s’agissait de montrer une usine pétrochimique moderne qui devait servir, selon les intentions de l’ENI, de modèle pour le développement économique et social de la zone entière. Les trois documentaires
ont été ménés en analysant les sources d’archives relatives aux
processus de production. Il représentent, de même qu’une grande partie
des résultats du cinema industriel, un ensemble de témoignages très
utiles pour nous aider à regarder les bons et les mauvais côtés d’un certain nombre d’aspects cruciaux qui se sont déterminés au cours de ces
années de progressive transformation économique et indutrielle de la
géographie de notre pays.

BIOCOMPATIBILITà DEI MATERIALI DENTARI
Creators: name: Rivieccio, Virginia
Publisher: name: Università degli Studi di Napoli Federico II
Year: 2013

description: I composti dentari in resina sono biomateriali usati per il ristoro estetico di strutture e funzioni di denti compromessi da carie, erosioni e fratture.
Di conseguenza, sono disponibili diversi materiali resinosi, ma nonostante varie modifiche nella formulazione, la composizione chimica delle resine composite comprende particelle inorganiche, e additivi che vengono incorporati in una matrice di resina organica.
La matrice organica è spesso composta da diversi tipi di monomeri e quelli più impiegati sono il 2-idrossietil metacrilato (HEMA) e il trietilenglicol-dimetacrilato (TEGDMA).
Precedenti studi in vitro hanno dimostrato che questi monomeri possono causare significative alterazioni del normale processo di differenziazione dei fibroblasti pulpari in odontoblasti. La citotossicità dei monomeri potrebbe essere causata da una perdita dell’equilibrio redox cellulare pro- e antiossidante con conseguente aumento dei livelli di ROS. È noto però che esistono molecole come N-Acetilcisteina (NAC), in grado di ridurre gli effetti negativi e di aumentare gli effetti vantaggiosi dei materiali dentari. Alcuni studi in vitro sulla biocompatibilità dei materiali dentali riportano che la quantità di sostanze rilasciate da RBM potrebbe dipendere dal mezzo di estrazione.
Per tanto lo scopo del lavoro è stato quello di valutare, partendo dall'ipotesi che solventi come DMSO e EtOH possono influenzare la citotossicità cellulare e l’azione dei monomeri, come varia sia la concentrazione attiva del TEGDMA nel terreno di coltura cellulare sia la citotossicità e i livelli di produzione di ROS. Inoltre, poiché il TEGDMA contiene la stessa identica porzione metacrilica della molecola di HEMA, abbiamo ipotizzato che anch’esso potrebbe legarsi covalentemente al NAC con la conseguente formazione di addotti NAC-TEGDMA, i quali potrebbero contribuire a mitigare gli effetti tossici del monomero stesso. Infine, alla luce del fatto che gli adesivi dentali contengono monomeri come HEMA, tranne per alcuni nuovi adesivi three-step etch&rinse e one-step che sono liberi da HEMA, e che ogni componente di un sistema adesivo ha in qualche misura un effetto specifico sulla forza di adesione, resistenza, durata di conservazione e biocompatibilità, abbiamo voluto confrontare gli adesivi Hema-Free con un adesivo contenente il monomero, per valutarne la citotossicità, la vitalità cellulare e la produzione di ROS.

description: We present the results of a computer simulation study of thermodynamical properties of TIP4P water confined in a hydrophobic disordered matrix of soft spheres upon supercooling. The hydrogen bond network of water appears preserved in this hydrophobic confinement. Nonetheless a reduction in the average number of hydrogen bonds due to the geometrical constraints is observed. The liquid branch of the spinodal line is calculated from 350 K down to 210 K. The same thermodynamic scenario of the bulk is found: the spinodal curve is monotonically decreasing. The line of maximum density bends avoiding a crossing of the spinodal. There is however a shift both of the line of maximum density and of the spinodal toward higher pressures and lower temperatures with respect to bulk.

A general framework for predictive economic evaluation of computerized hospital information systems and an application to a British Columbia hospital
Creators: name: Lindstrom, Ronald Raymond
Publisher: name: University of British Columbia
Year: 2010

description: Hospital decision-makers face several uncertainties during evaluation and selection of computerized hospital information systems. Cost-benefit analysis is one method of predictive economic evaluation and is particularly important from the perspective of the hospital. Unless hospitals can economically justify such systems, it makes little sense to pursue them unless there are over-riding political or qualitative reasons. This thesis discusses the principles of cost-benefit analysis and a general framework for such analysis from the perspective of the hospital, in order to answer the question of whether a proposed hospital information system is justifiable on cost-benefit grounds relative to the status quo method of handling information. Three dominant approaches to planning for such systems in British Columbia and Ministry of Health funding guidelines and policies are discussed in relation to the framework. An application of the framework is made to a community general hospital in British Columbia using actual data obtained during the complete planning process for a proposed system. The analysis demonstrates that over the expected duration of the project, the sample hospital will experience net costs, as opposed to net savings for the proposed system, even if all one-time capital costs are funded by others. It is unlikely that this finding is unique to this single hospital; thus, there are broader implications for other hospitals considering such systems, especially in the face of recently published expenditure limits and priorities in British Columbia.

Punti di vista e ascolto nel paesaggio protetto recensione al documentario “Good morning mountain!” (10’)
Creators: name: Goina, Maurizio

Publisher: name: Semestrale di studi e ricerche di geografia
Year: 2017

description: Il documentario “Good Morning Mountain!” si sofferma sulla vita
delle genti di montagna e sui loro ritmi quotidiani, riconoscendo che le
aree protette sono uno strumento importante di tutela naturalistica e di
valorizzazione del territorio. Questa narrazione audiovisiva cerca di
raccontare la quotidianità in un contesto rurale montano. A tale scopo
viene ricostruita la giornata tipo di un abitante del parco.

Nel 1924 la valle dei laghi del Triglav fu designata area protetta, ed in seguito il regime di tutela fu esteso ad altre aree limitrofe (nel 1961 e nel 1981) fino a ricoprire tutta l’area dell’arco alpino sloveno, oggi conosciuta come Parco Nazionale del Triglav.

description: A cryogenic 22-pole ion trap apparatus is used in combination with a table-top pulsed IR source to probe weakly bound CH$^+$-He and CH$^+$-He$_4$ complexes by predissociation spectroscopy at 4 K. The infrared photodissociation spectra of the C-H stretching vibrations are recorded in the range of 2720-2800 cm$^{-1}$. The spectrum of CH$^+$-He exhibits perpendicular transitions of a near prolate top with a band origin at 2745.9 cm$^{-1}$, and thus confirms it to have a T-shaped structure. For CH$^+$-He$_4$, the C-H stretch along the symmetry axis of this oblate top results in parallel transitions.

description: Converging Zero Trust (ZT) with learning techniques can solve various operational and security challenges in Distributed Computing Continuum Systems (DCCS). Implementing centralized ZT architecture is seen as unsuitable for the computing continuum (e.g., computing entities with limited connectivity and visibility, etc.). At the same time, implementing decentralized ZT in the computing continuum requires understanding infrastructure limitations and novel approaches to enhance resource access management decisions. To overcome such challenges, we present a novel learning-driven ZT conceptual architecture designed for DCCS. We aim to enhance ZT architecture service quality by incorporating lightweight learning strategies such as Representation Learning (ReL) and distributing ZT components across the computing continuum. The ReL helps to improve the decision-making process by predicting threats or untrusted requests. Through an illustrative example, we show how the learning process detects and blocks the requests, enhances resource access control, and reduces network and computation overheads. Lastly, we discuss the conceptual architecture, processes, and provide a research agenda.

CORE-SHELL SUSTAINED
RELEASE NANOSYSTEMS FOR THE INTRAVENOUS DELIVERY OF ANTICANCER DRUGS
Creators: name: Conte, Claudia
Publisher: name: Università degli Studi di Napoli Federico II
Year: 2013

description: In the last few years, an increased interest is being focused on the development of sustained release nanocarriers pointing to their possible application as intravenous nanomedicines with better performance and lower toxicity as compared to free drugs. We designed and tested several core-shell nanocapsules and nanoparticles (NPs), for the intravenous delivery of both  hydrophilic and lipophilic drugs respectively. As base materials, we employed biodegradable amphiphilic block copolymers of poly(-caprolactone) (PCL) and poly(ethyleneoxide) (PEO) with different architectures.
In the first stage of the project, stealth aqueous core nanocapsules for the delivery of  hydrophilic molecules were prepared by the novel Emulsion/Melting-Sonication technique. Nanocapsules showed optimized technological properties (size, polidispersity index, zeta potential, entrapment efficiency and release rate) and an encouraging cytotoxicity profile, thus representing a nanosystem of great potential in several drug delivery applications, especially for passive targeting of hydrophiphilic drugs to solid tumors.
In the second part of the work, core-shell PEO-PCL NPs for the sustained delivery of the highly lipophilic anticancer drug docetaxel (DTX) were obtained by the Melting-Sonication method. NPs were able to entrap high amounts of DTX related to copolymer properties, thus sustaining its release along time and not toxicity toward red blood cells was evidenced. A stronger efficiency in inhibiting cell growth of breast and prostate cancer cells than the free drug and not toxicity in experimental animal models were highlighted.
As a final step, we combined DTX with zinc-phtalocyanine (ZnPc), a second generation photosensitizer used in Photodynamic Therapy (PDT), with the aim to obtain a combined chemio/photodynamic nanomedicine. Combined NPs provided high DTX and ZnPc loadings, a slow release of the chemotherapeutic drug and high efficacy of the photosensitizing agent  in the singlet oxygen generation. Their high stability in biological environments and the encouraging results obtained by the in vitro data on HeLa cells and by in vivo data  on an orthotopic mouse model of amelanotic melanoma, suggested the possibility to employ this system as a translational injactable nanomedicine for the synergistic combination of chemotherapy and PDT.

Quark matter with an anisotropic momentum distribution

description: Motivated by the anisotropic momentum distribution of particles in heavy-ion collisions, we study the angular dependence of quark average momentum and quark distribution function in the Polyakov-Nambu--Jona-Lasinio (PNJL) quark model. We also investigate the phase transitions and net baryon number fluctuations in anisotropic quark matter. The numerical results suggest that the QCD phase structure and isentropic trajectories are sensitive to the anisotropic parameter at finite density, in particular, in the area near the critical region and the first-order phase transition. Compared with the isotropic quark matter, the values of baryon number kurtosis and skewness at lower collision energies are possibly enhanced with the anisotropic momentum distribution squeezed along the direction of nucleus-nucleus collision in experiments.

description: In the near future, the overlap of the Rubin Observatory Legacy Survey of Space and Time (LSST) and the Simons Observatory (SO) will present an ideal opportunity for joint cosmological dataset analyses. In this paper we simulate the joint likelihood analysis of these two experiments using six two-point functions derived from galaxy position, galaxy shear, and CMB lensing convergence fields. Our analysis focuses on realistic noise and systematics models and we find that the dark energy Figure-of-Merit (FoM) increases by 53% (92%) from LSST-only to LSST+SO in Year 1 (Year 6). We also investigate the benefits of using the same galaxy sample for both clustering and lensing analyses, and find the choice improves the overall signal-to-noise by ~30-40%, which significantly improves the photo-z calibration and mildly improves the cosmological constraints. Finally, we explore the effects of catastrophic photo-z outliers finding that they cause significant parameter biases when ignored. We develop a new mitigation approach termed "island model", which corrects a large fraction of the biases with only a few parameters while preserving the constraining power.

description: Ho assistito, a Firenze, a una gran parte del ‘Forum dei Giovani
Studiosi’. E ricordo che la prima osservazione che mi è venuta in
mente, proprio appena preso posto e ascoltate due battute di Franco
Farinelli, è stata che il tavolo della presidenza non pareva corrispondere
esattamente (non me ne vogliano, per carità, i colleghi) allo stato anagrafico presupposto dalla intitolazione del ‘Forum’. Gli interventi successivi – i lunghi interventi di colleghi ‘autorevoli’, cioè ‘non giovani’ – avevano finito per rafforzare la stessa impressione.
A maggior ragione, ho evitato, allora, di intervenire nella discussione.
Sono però molto grato, ora, che mi sia stato chiesto un intervento su
quei temi e in risposta alla ‘lettera aperta’ dei GiGi 13, così come ero
andato con molto interesse (non tradito, in fondo, dai fatti) a seguire a
Firenze il ‘Forum’ – che mi era parso segnale di una comunque ottima
intenzione, fatti a parte.
