description: Multi-agent systems cooperation to achieve global goals is usually limited by sensing, actuation, and communication issues. At the local level, continuous measurement and actuation is only approximated by the use of digital mechanisms that measure and process information in order to compute and update new control input values at discrete time instants. Interaction with other agents or subsystems takes place, in general, through a digital communication channel with limited bandwidth where transmission of continuous-time signals is not possible. Additionally, communication channels may be subject to other imperfections such as time-varying delays. This paper considers the problem of consensus (or synchronization of state trajectories) of multi-agent systems that are described by general linear dynamics and are connected using undirected graphs. An event-triggered consensus protocol is proposed, where each agent implements discretized and decoupled models of the states of its neighbors. This approach not only avoids the need for continuous communication between agents but also provides a decentralized method for transmission of information in the presence of time-varying communication delays where each agent decides its own broadcasting time instants based only on local information. This method gives more flexibility for scheduling information broadcasting compared to periodic and sampled-data implementations. The use of discretized models by each agent allows for a periodic event-triggered strategy where continuous actuation and continuous measurement of the states are not necessary.

description: Da diversi decenni, l?immigrazione � un tema caldo per l?opinione pubblica dei paesi europei (e non). Vi � una diffusa insoddisfazione per la capacit� delle politiche adottate di favorire effettivamente l?�integrazione� dei segmenti di popolazione straniera residenti sul territorio. In che misura questa insoddisfazione coglie una difficolt� reale? Per saperlo, bisognerebbe essere in grado di definire con esattezza cosa debba intendersi per �integrazione�, come essa andrebbe misurata e, last but not least, come valutare se le politiche messe in atto dai governi occidentali producono o meno gli effetti desiderati. Su ognuno di questi punti, esiste un ricco dibattito scientifico spesso poco conosciuto. In questo lavoro viene condotta una rassegna critica della letteratura scientifica sul tema, volta ad evidenziare le risorse gi� disponibili e i problemi ancora aperti.

description: Masked hypertension (MH)—nonelevated office blood pressure (BP) with elevated out-of-office BP average—conveys cardiovascular risk similar to or approaching sustained hypertension, making its detection of potential clinical importance. However, it may not be feasible or cost-effective to perform ambulatory BP monitoring (ABPM) on all patients with a nonelevated office BP. There likely exists a level of office BP below which ABPM is not warranted because the probability of MH is low.

description: In this paper we refine the main result of a previous paper of the author with Grimeland on derived invariants of surface algebras. We restrict to the case where the surface is a torus with one boundary component and give an easily computable derived invariant for such surface algebras. This result permits to give answers to open questions on gentle algebras: it provides examples of gentle algebras with the same AG-invariant (in the sense of Avella-Alaminos and Geiss) that are not derived equivalent and gives a partial positive answer to a conjecture due to Bobiński and Malicki on gentle $2$-cycles algebras.

ERALPHA: THE CROSSROAD BETWEEN METABOLIC FITNESS AND METABOLIC ILLNESS
Creators: name: LOLLI, FEDERICA
Publisher: name: Universit� degli Studi di Milano

description: Oestrogens are important regulators of energy homeostasis and lipid metabolism, acting both centrally and peripherally and, indeed, the impairment of oestrogen signalling is associated with the development of several metabolic diseases. The alpha isoform of the oestrogen receptor (ER?) is predominant in the liver and studies carried out in several laboratories, including ours, have shown that hepatic ER? exerts a major role in the control of lipid metabolism. Recently, we demonstrated the pivotal role played by oestrogens and ER? in female liver physiology. Indeed, our studies have shown that in female mammals hepatic ER? has a pivotal role in adapting energy metabolism to the needs of reproductive functions and that is transcriptionally regulated by estrogens and food intake. On the other hand in males, the expression of hepatic ER? is significantly lower than in females, yet its activity is highly regulated by food intake indicating that also in males hepatic ER? might have a role in the control of lipid metabolism. This led us to further investigate the activity of hepatic ER? in males and the aim of this study was to compare female and male liver metabolism and to unravel the role, if any, played by hepatic ER? in the regulation of energy metabolism in male mice. We performed this study in homeostatic conditions and in a stressed metabolic status, caused by the administration of an unbalanced diet. We analysed, with different techniques, key metabolic and inflammatory pathways in female and male control (SYN) and LERKO (Liver ER? knockout) mice fed with control diet (ND) or high fat diet (HFD) and the LERKO mouse model, generated by our lab, allowed us to single out the activity of hepatic ER?. This comprehensive study revealed that both metabolic and inflammatory pathways are different between females and males in homeostatic conditions and that the administration of HFD, per se or also in combination with the selective ablation of hepatic ER?, leads to different outcomes depending on sex. Moreover, the results of this work allowed us to identify the sex specific role of hepatic ER? in the regulation of liver metabolism and inflammation in normal or stressed metabolic conditions, and, interestingly, to highlight ER? possible opposite regulatory action in female and male metabolism. We believe that this is very relevant from both a pharmacological and a pathophysiological point of view. Indeed, the identification of a sex dependent regulatory action of ER? on metabolism would not only provide the conceptual bases for future therapeutic interventions, able to mimic the beneficial effect of oestrogens and ER? on metabolic parameters, but also further stress the necessity to consider sex as an essential biological variable in the design of personalized pharmacological therapies.

Year: 2019

description: In this thesis the results obtained during the three years of doctorate (2015-2018) will be illustrated. Although several different computational and crystallographic techniques have been exploited throughout my research activity, almost all projects were linked by a common thread: halogen bond (XB), a non-covalent interaction the nature of which will be briefly illustrated in the introduction section of the thesis together with a brief description of the state of art of the research on this interaction. Among XB project present in my PhD thesis, it is worth mentioning the presence of an experimental and theoretical charge density study of crystals containing XB interacting molecules, the development of a new method to treat chlorine XB by means of classical force field and a valence bond study of bromine XB. Beside halogen bonding, a brand new method (the X-Ray Constrained Spin-Coupled, XCSC) has been developed in the framework of quantum crystallography.

IDENTIFYING THE MOLECULAR PLAYERS ASSOCIATED WITH TRANSITION BETWEEN PLURIPOTENT AND TOTIPOTENT-LIKE STATES

Publisher: name: Universit� degli Studi di Milano
Year: 2017

description: The presence of rare transient cells within pluripotent stem cell population that resemble functional and transcriptional features of totipotent 2-cell-stage embryos has emerged several questions regarding their mechanism of reactivation. Although few recent works have aimed to characterize them both at transcriptional and functional level, the mechanism of transition to 2C-like state is poorly investigated. Here we identified a new pathway, whose activation through several compounds could induce transition to 2C-like state. Interestingly, inhibition of this pathway by specific inhibitors could collectively restrain the majority of the 2C-like state transcriptional alterations including MuERV-L and Zscan4 gene family. Finally, we found that developmental potential of induced 2C-like cells could be extended to embryonic plus extra-embryonic tissues in contrast to embryonic stem cells in culture. Our finding provides a better understanding of cellular plasticity at early embryonic state, which could be important for the potential therapeutic avenues.

description: Cognitive test performance is decreased in hypertensive adults and children, a finding postulated to represent early target-organ damage to the brain. Hypertensive children are often obese, a comorbidity associated with sleep disordered breathing (SDB), itself associated with cognitive problems; potentially confounding the relation between hypertension (HTN) and neurocognition. Our objective was to determine the association between SDB as measured by a scale and questionnaire score and neurocognition among participants enrolled in an ongoing multicenter study of cognition in children with HTN.
The Darkest Hour: Private Information Control and the End of Democratic Science

description: The evaluation of scientific research is based on data protected by secrecy and intellectual property (e.g., Elsevier Scopus or Clarivate Web of Sci-ence). The peer review process is essentially anonymous. While science has progressed thanks to public dialogue, the current evaluation system is centered on private control of information. This represents a fundamental shift from democratic to authoritarian science. Open Science may confront this change only if it is accepted as the heir, in the digital age, of the values and principles that public and democratic science has traditionally fostered in the age of printing, thus becoming the guardian of a democratic society.
EXPLORING THE ORIGIN OF SUBSTRUCTURES IN PLANET FORMING DISCS.THE ROLE OF PROTOPLANETS AND OF GRAVITATIONAL INSTABILITIES

Year: 2021

description: Recent high resolution and high sensitivity observations of protoplanetary discs are showing us peculiar substructures, such as spirals, gaps and rings. Disc hydrodynamical instabilities, such as gravitational instabilities induced by the disc self-gravity, and embedded protoplanets have been proposed to be responsible for their formation. However, the origin of these substructures is still very debated, in particular it is not clear how their morphological and kinematical features depend on the disc mass, on the embedded companion mass and on the coupling between the gas and the dust component of the disc. This project aims at deepen our knowledge of the processes that originate the observed substructures, focusing on these three aspects.

description: The brāmhaṇ who came from the Central Asian steppes were neither acclimatized to the coastal environment nor had a natural inclination for maritime travel; two reasons that seem to have led the sārasvat to undertake the perilous journey from Kuśasthaḷī in Kāṭhīyāvāḍ to Kuśasthaḷī in Goa. Not to mention their matsyabhakṣak diet; for which reason Sahyādrikhaṇḍ had to import them specifically from Trihotra. These basic divergences of the sārasvat from the ‘true’ brāmhaṇ, defy explanation. The difference between the sārasvat diet and that of the deśasth, however could have an explanation. When the brāmhaṇ came into India, they continued with the matsyabhakṣak - māṁsbhakṣak diet they had inherited from the steppes of Central Asia. It is only when they reached the eastern end of the Indo-Gangetic plain, that is the Yamunā - Gangā doab, that they seem to have come under the jaina influence and dropped fish and meat from their diet. Vaidya holds that “many of the subcastes of Brahmins especially in northern India were then non-vegetarian and they continue to be so down to this day.” [Vaidya, 1926 : History Of Medieval Hindu India, Vol. 3, 381]
CHLORIDE INTRACELLULAR ION CHANNEL 1 AS A CUTTING EDGE BETWEEN NEUROGENESIS AND NEURODEGENERATION.
Creators: name: AVERAIMO, STEFANIA
Publisher: name: Universit� degli Studi di Milano
Year: 2012

description: Chloride intracellular ion channel 1 (CLIC1) has peculiar properties compared to most known ion channels, in that it exists both as a soluble protein and as a membrane-integrated protein. Previous studies have shown that CLIC1 insertion into the plasma membrane is driven by different stimuli such as oxidation, cytoplasmic acidification, increased calcium concentration. Once inserted into the plasma membrane CLIC1 forms a chloride selective ion channel. The best characterized mechanism leading CLIC1 into the plasma membrane is cell oxidation. Our laboratory has previously shown that in microglia cells stimulation by amyloid beta peptides, one of the most common hallmarks of Alzheimer disease (AD), determines the increase of CLIC1-mediated current. Many studies have demonstrated that many AD patients show at first visual impairment rather than other cognitive deficits. AD patients show severe abnormalities in the structure and function of the retina, including retinal ganglion cells (RGCs) loss. Several cellular mechanisms precede RGCs degeneration, including oxidative stress. Therefore, in view of the oxidation-driven behavior of CLIC1, during my PhD, I analyzed CLIC1 expression in mouse retina. We found out that CLIC1 expression is increased in retinas of two different AD mouse models. Interestingly, CLIC1 increased expression is prior to the manifestation of the first cognitive symptoms, thus proposing CLIC1 as an early marker of neurodegeneration in AD. Although CLIC1 expression is largely increased in AD mouse retinas, CLIC1 is also expressed in wild type retinas, mainly in the gangliar layer, where the nuclei of RGCs, whose axons make up the optic nerve, are located. Thus, we wondered about the role of CLIC1 in the normal RGCs physiology. Our studies unraveled the crucial role of CLIC1-mediated current in axon outgrowth of RGCs, showing that the inhibition of the chloride current causes a reduced axon outgrowth that is parallel to an altered morphology of the growth cones and a reduced co-localization of CLIC1 with the actin cytoskeleton. Our results also suggest that CLIC1 involvement in axon outgrowth might be due to CLIC1 modulation by cAMP. Taken together our data propose cAMP, or cAMP homologues, as a putative tool to modulate CLIC1 transient expression at the plasma membrane and consequently axon outgrowth.

description: Fractional Chern insulators are the proposed phases of matter mimicking the physics of fractional quantum Hall states on a lattice without an overall magnetic field. The notion of Floquet fractional Chern insulators refers to the potential possibilities to generate the underlying topological bandstructure by means of Floquet engineering. In these schemes, a highly controllable and strongly interacting system is periodically driven by an external force at a frequency such that double tunneling events during one forcing period become important and contribute to shaping the required effective energy bands. We show that in the described circumstances it is necessary to take into account also third order processes combining two tunneling events with interactions. Referring to the obtained contributions as micromotion-induced interactions, we find that those interactions tend to have a negative impact on the stability of of fractional Chern insulating phases and discuss implications for future experiments.

description: We present version 8 of the CHIANTI database. This version includes a large amount of new data and ions, which represent a significant improvement in the soft X-ray, EUV and UV spectral regions, which several space missions currently cover. New data for neutrals and low charge states are also added. The data are assessed, but to improve the modelling of low-temperature plasma the effective collision strengths for most of the new datasets are not spline-fitted as previously, but are retained as calculated. This required a change of the format of the CHIANTI electron excitation files. The format of the energy files has also been changed. Excitation rates between all the levels are retained for most of the new datasets, so the data can in principle be used to model high-density plasma. In addition, the method for computing the differential emission measure used in the CHIANTI software has been changed.

Study of the anisotropic sintering shrinkage of green iron and stainless steel
Creators: name: Baselli, Silvia
Publisher: name: Universit� degli studi di Trento
Year: 2020

description: Powder metallurgy (PM) is a near net-shape technology that guarantees excellent dimensional control and surface finishing in the production of parts with complex shapes. Press and sinter is the conventional PM process. The powder mix is compacted into rigid dies to obtain the so called green part that is subsequently sintered to promote the formation of metallic bonding between the powder particles. The differences in terms of geometrical and dimensional features between the green compact and the final part are related to the dimensional variations occurring during sintering, therefore, to preserve the cost effectiveness of the process, their in-depth knowledge is crucial. In this context, post- sintering machining should be limited to the realization of geometrical details that cannot be directly obtained through uniaxial cold compaction or to achieve strict tolerances required by specific applications. The dimensional changes in sintering that may be either shrinkages or swellings are affected by many parameters and, among them, we can consider: material, presence of lubricant and additives, green density, compaction strategy, sintering temperature and time, atmosphere, heating and cooling rate. Furthermore, the dimensional variations along the direction parallel to compaction (longitudinal, axial) are different from the dimensional variations in the compaction plane (transversal, radial) causing an anisotropy that depends, in addition to the mentioned parameters, on the geometry and the dimension of the part. At present, in absence of an adequate designing tool to account for the anisotropy, engineers rely on empirical methods often based on the trial-and-error approach.
HERBICIDE TRANSPORT FROM LAND TO SURFACE WATER IN AN ARTIFICIALLY DRAINED CATCHMENT
Creators: name: TEDIOSI, ALICE
Publisher: name: Universit� degli Studi di Milano
Year: 2010

description: Pesticide use is often associated with a number of negative impacts on the environment and on water quality. In this thesis the processes contributing to herbicide transport from land to surface water were examined, using a combination of existing data analysis, modelling, and monitoring. Field investigations of herbicide transport were conducted on an artificially drained field dominated by heavy clay soil (Denchworth soil association), in the Upper Cherwell catchment (UK). The main drain was monitored over five months during November 2009 to March 2010, when the field was in oilseed rape (OSR) and was treated with propyzamide and carbetamide. In the UK recent attention has focused on these two herbicides, which are used to control black grass in OSR. Both chemicals were detected at very high concentrations (up to 55.7 ?g l-1 and 694 ?g l-1 for propyzamide and carbetamide, respectively). The concentration pattern clearly followed drain discharge, with rapid increase on the rising hydrograph limb and a quasi-exponential decline on the recession limb. The MACRO pesticide fate model, which was applied to represent field observations, supported the hypothesis that herbicide transport to drains is a very quick process and suggested that preferential flow is a major transport mechanism. This analysis has contributed to the development of a preliminary model of catchment-scale pesticide transfers, which integrates hillslope responses through the river network to simulate flow and herbicide losses at the catchment outlet. The application of this model tends to corroborate the hypothesis that rapid transport to drains play a major role in herbicide contamination of surface water at the catchment outlet. Herbicides seem to peak about one day after rainfall events. The results also suggest that the first few rain events following herbicide application are very critical in terms of chemical losses.

description: Das Handwerk ist verschiedenen technologiebedingten Veränderungen unterworfen. Es wurde bisher kaum untersucht, welche Handwerksunternehmen von dieser Entwicklung in welcher Weise betroffen sind. Handwerksbetriebe haben z.B. seit einiger Zeit die Möglichkeit, Online-Plattformen, wie MyHammer zu nutzen, um neue Kunden zu akquirieren. In dieser Studie werden Betriebe beschrieben, die diese Art der Digitalisierung in Anspruch genommen haben, und deren Auswirkungen untersucht. Insbesondere wird gezeigt, dass ein typisches Handwerksunternehmen auf MyHammer eine kleiner Betrieb ist, der nach der Reform der Handwerksordnung im Jahr 2004 gegründet wurde und über geringere formelle Qualifikationen verfügt. Zudem wird nachgewiesen, dass Meisterbetriebe, obwohl sie kommerzielle Online-Vertriebskanäle weniger häufig nutzen, mehr Erfolg haben als Nicht- Meister-Betriebe. Sie erzielen eine höhere Kundenzufriedenheit und verbleiben länger auf der Plattform. Da Meisterbetriebe eine höhere Dienstleistungsqualität aufweisen als Nicht- Meisterbetriebe, kann angenommen werden, dass die Abschaffung der Meisterpflicht seit 2004, zu einer niedrigeren durchschnittlichen Qualität im Markt geführt hat.

description: Zero-range processes with decreasing jump rates are known to exhibit condensation, where a finite fraction of all particles concentrates on a single lattice site when the total density exceeds a critical value. We study such a process on a one-dimensional lattice with periodic boundary conditions in the thermodynamic limit with fixed, super-critical particle density. We show that the process exhibits metastability with respect to the condensate location, i.e. the suitably accelerated process of the rescaled location converges to a limiting Markov process on the unit torus. This process has stationary, independent increments and the rates are characterized by the scaling limit of capacities of a single random walker on the lattice. Our result extends previous work for fixed lattices and diverging density in [J. Beltran, C. Landim, Probab. Theory Related Fields, 152(3-4):781-807, 2012], and we follow the martingale approach developed there and in subsequent publications. Besides additional technical difficulties in estimating error bounds for transition rates, the thermodynamic limit requires new estimates for equilibration towards a suitably defined distribution in metastable wells, corresponding to a typical set of configurations with a particular condensate location. The total exit rates from individual wells turn out to diverge in the limit, which requires an intermediate regularization step using the symmetries of the process and the regularity of the limit generator. Another important novel contribution is a coupling construction to provide a uniform bound on the exit rates from metastable wells, which is of a general nature and can be adapted to other models.

description: In this chapter we analyze in detail the behaviour and properties of the kinks found in an one dimensional model for the close packed rows of potassium ions in mica muscovite. The model includes realistic potentials obtained from the physics of the problem, ion bombardment experiments and molecular dynamics fitted to experiments. These kinks are supersonic and have an unique velocity and energy. They are ultradiscrete involving the translation of an interstitial ion, which is the reason they are called 'crowdions'. Their energy is below the most probable source of energy, the decay of the $^{40}$K isotope and above the energy needed to eject an atom from the mineral, a phenomenon that has been observed experimentally

description: Nearly one of every three workers in the United States is low-income. Low-income populations have a lower life expectancy and greater rates of chronic diseases compared to those with higher incomes. Low- income workers face hazards in their workplaces as well as in their communities. Developing integrated public health programs that address these combined health hazards, especially the interaction of occupational and non-occupational risk factors, can promote greater health equity. We apply a social-ecological perspective in considering ways to improve the health of the low-income working population through integrated health protection and health promotion programs initiated in four different settings: the worksite, state and local health departments, community health centers, and community-based organizations. An example of successful approaches to developing integrated programs in each of these settings is described. Recommendations for improved research, training, and coordination among health departments, health practitioners, worksites and community organizations are proposed.

description: Wir sind fasziniert von der Größe eines Airbus A380 - ein Superlativ im Passagierflugzeugbau. Gleichzeitig stellen wir uns die Fragen: Könnten Flugzeuge sinnvollerweise auch noch größer gebaut werden? Wie sieht das Flugzeug der Zukunft aus? Weltweit geht man auch in Industrie, Großforschungseinrichtungen und Hochschulen diesen Fragen nach. Dabei wird zur Zeit gerade eine Konfiguration besonders intensiv betrachtet: Die Blended Wing Body (BWB) Flugzeugkonfiguration. Basierend auf Recherchen und den eigenen Arbeiten der HAW Hamburg versucht Prof. Scholz Bilanz zu ziehen und aufzuzeigen, welche Möglichkeiten aber auch Herausforderungen in der BWB Konfiguration stecken.

description: We evaluate the effectiveness of deep learning (DL) models for reconstructing the masses of galaxy clusters using X-ray photometry data from next-generation surveys. We establish these constraints using a catalogue of realistic mock eROSITA X-ray observations which use hydrodynamical simulations to model realistic cluster morphology, background emission, telescope response, and AGN sources. Using bolometric X-ray photon maps as input, DL models achieve a predictive mass scatter of $σ_{\ln M_\mathrm{500c}} = 17.8\%$, a factor of two improvements on scalar observables such as richness $N_\mathrm{gal}$, 1D velocity dispersion $σ_\mathrm{v,1D}$, and photon count $N_\mathrm{phot}$ as well as a $32\%$ improvement upon idealised, volume-integrated measurements of the bolometric X-ray luminosity $L_X$. We then show that extending this model to handle multichannel X-ray photon maps, separated in low, medium, and high energy bands, further reduces the mass scatter to $16.2\%$. We also tested a multimodal DL model incorporating both dynamical and X-ray cluster probes and achieved marginal gains at a mass scatter of $15.9\%$. Finally, we conduct a quantitative interpretability study of our DL models and find that they greatly down-weight the importance of pixels in the centres of clusters and at the location of AGN sources, validating previous claims of DL modelling improvements and suggesting practical and theoretical benefits for using DL in X-ray mass inference.

description: We present a fully grid-based approach for solving Hartree-Fock and all-electron Kohn-Sham equations based on low-rank approximation of three-dimensional electron orbitals. Due to the low-rank structure the total complexity of the algorithm depends linearly with respect to the one-dimensional grid size. Linear complexity allows for the usage of fine grids, e.g. $8192^3$ and, thus, cheap extrapolation procedure. We test the proposed approach on closed-shell atoms up to the argon, several molecules and clusters of hydrogen atoms. All tests show systematical convergence with the required accuracy.
