On the electrodynamics of moving particles in a quasi flat spacetime with Lorentz violation and its cosmological implications

description: This research aims to develop a new approach toward a consistent coupling of electromagnetic and gravitational fields by using an electron that couples with a weak gravitational potential by means of its electromagnetic field. We find the value of the tiny coupling constant of gravity with electromagnetic fields, which depends on the speed of light and a universal minimum speed that represents the lowest limit of speed for any particle. Such a minimum speed, unattainable by particles, represents a preferred reference frame associated with a background field that breaks the Lorentz symmetry. The metric of the flat spacetime shall include the presence of a uniform vacuum energy density, which leads to a negative pressure at cosmological scales, i.e., the cosmological anti-gravity. The tiny values of the cosmological constant and the vacuum energy density will be successfully obtained in agreement with the observational data.

description: The well known theorems of Khintchine and Jarník in metric Diophantine approximation provide comprehensive description of the measure theoretic properties of real numbers approximable by rational numbers with a given error. Various generalisations of these fundamental results have been obtained for other settings, in particular, for curves and more generally manifolds. In this paper we develop the theory for planar curves by completing the theory in the case of parabola. This represents the first comprehensive study of its kind in the theory of Diophantine approximation on manifolds.

description: Psoriasis is considered a widespread dermatological disease that can strongly affect the quality of life. Currently, the treatment is continued until the skin surface appears clinically healed. However, lesions appearing normal may contain modifications in deeper layers. To terminate the treatment too early can highly increase the risk of relapses. Therefore, techniques are needed for a better knowledge of the treatment process, especially to detect the lesion modifications in deeper layers. In this study, we developed a fiber-based SORS-SERDS system in combination with machine learning algorithms to non-invasively determine the treatment efficiency of psoriasis. The system was designed to acquire Raman spectra from three different depths into the skin, which provide rich information about the skin modifications in deeper layers. This way, it is expected to prevent the occurrence of relapses in case of a too short treatment. The method was verified with a study of 24 patients upon their two visits: the data is acquired at the beginning of a standard treatment (visit 1) and four months afterwards (visit 2). A mean sensitivity of ≥85% was achieved to distinguish psoriasis from normal skin at visit 1. At visit 2, where the patients were healed according to the clinical appearance, the mean sensitivity was ≈65%.

description: Die Korrespondenzanalyse (CA) ist ein wohlbekanntes Verfahren, um geschlossene Fundkomplexe zu seriieren. Ein Problem dabei ist, daß man mit der CA nur die relative Chronologie der Fundkomplexe erhält. Doch die Publikationen von GROENEN & POBLOME (2003) sowie POBLOME & GROENEN (2003) stellen ein Verfahren zur bedingten Korrespondenzanalyse vor, bei dem Zusatzinformationen in Form von Gleichungen und Ungleichungen für die Datierungen der Fundkomplexe berücksichtigt werden. Damit kann nicht nur das CA-Ergebnis verbessert werden, es ist auch möglich, absolute Datierungen für die Fundkomplexe zu errechnen. Der Aufsatz untersucht die Genauigkeit der bedingten CA mit Hilfe von Simulationsexperimenten. Konkret gesagt prüfen wir, wie gut die normale wie auch die bedingte CA in der Lage sind, die zeitliche Reihenfolge und die absoluten Datierungen zu rekonstruieren. Indem wir die Zahl der Zusatzinformationen und ihre Art (Gleichungen, Ungleichungen) variieren, erforschen wir, wie viele solcher Zusatzbedingungen notwendig sind, um eine zuverlässige zeitliche Einordnung zu erhalten. Die Simulationsexperimente orientieren sich an einem Datensatz aus Sagalassos (SW-Türkei) mit lokal hergestellter Keramik.
description: Correspondence analysis (CA) is a well-known technique for the seriation of archaeological assemblages. One problem with the CA seriation Solution isthat only a relative ordering of the assemblages is obtained. However, GROENEN & POBLOME (2003) and POBLOME & GROENEN (2003) proposed a constrained CA approach that incorporates additional information, in the form of equality and inequality constraints concerning the time points of the assemblages, in order to improve the usual CA Solution. Using such constraints, explicit dates can be assigned to the seriation Solution. In this paper, we study the quality of the constrained CA Solution more closely using a Simulation study. To be more precise, we study how well ordinary and constrained CA are able to recover the time order and the explicit dates. Moreover, by varying the amount and type (equality, inequality) of constraints, we investigate how much extra information is required to obtain a satisfactory reproduction of the true time frame. The Simulation study is set up in such a way that it mimics the data of a series of ceramic assemblages consisting of the locally produced tableware from Sagalassos (SW Turkey).

description: We present a series of high-resolution cosmological simulations of galaxy formation to z=0, spanning halo masses ~10^8-10^13 M_sun, and stellar masses ~10^4-10^11. Our simulations include fully explicit treatment of both the multi-phase ISM (molecular through hot) and stellar feedback. The stellar feedback inputs (energy, momentum, mass, and metal fluxes) are taken directly from stellar population models. These sources of stellar feedback, with zero adjusted parameters, reproduce the observed relation between stellar and halo mass up to M_halo~10^12 M_sun (including dwarfs, satellites, MW-mass disks, and small groups). By extension, this leads to reasonable agreement with the stellar mass function for M_star<10^11 M_sun. We predict weak redshift evolution in the M_star-M_halo relation, consistent with current constraints to z>6. We find that the M_star-M_halo relation is insensitive to numerical details, but is sensitive to the feedback physics. Simulations with only supernova feedback fail to reproduce the observed stellar masses, particularly in dwarf and high-redshift galaxies: radiative feedback (photo-heating and radiation pressure) is necessary to disrupt GMCs and enable efficient coupling of later supernovae to the gas. Star formation rates agree well with the observed Kennicutt relation at all redshifts. The galaxy-averaged Kennicutt relation is very different from the numerically imposed law for converting gas into stars in the simulation, and is instead determined by self-regulation via stellar feedback. Feedback reduces star formation rates considerably and produces a reservoir of gas that leads to rising late-time star formation histories significantly different from the halo accretion history. Feedback also produces large short-timescale variability in galactic SFRs, especially in dwarfs. Many of these properties are not captured by common 'sub-grid' galactic wind models.

Latrinen und Abwurfhalden haben große Mengen an Tierknochen und botanischen Resten erbracht. Hinzu treten zeitgenössische Darstellungen von Märkten, Nahrungstransporten und Schnellimbissen. Sie sind Bestandteil des Bildprogramms einer Chronik aus der 2. Hälfte des 15. Jhs: der Chronik des Konstanzer Konzils 1414-1418,
verfasst von Ulrich Richental. Aus dieser Chronik erfahren wir Details über Handel, Marktpreise, Mietzins, Tagelöhne, sie berichtet über Festmähler und Picknicks, enthält aber auch allerlei Anekdoten.
Ergänzend treten die umfangreichen Bestände des Stadtarchivs Konstanz hinzu, welche in erfreulichem Maße publiziert vorliegen: Steuerlisten, Ratsbücher, Vermächtnisse, Codices und Gerichtsakten aller Art. Diese Quellen ermöglichen es, vielen Häusern über die Jahrhunderte hinweg Besitzer, Bewohner, Steuerlast und Mietzins zuzuordnen. Und damit auch den Latrinen ...
Diese QuellenTrias könnte nun tiefe Einblicke in Nahrung, Nahrungsmittel und Verbraucher im 15. Jh. bieten. Leider ist sie (noch?) ungenutzt---
description: In the case of the city of Constance w e are well equiped with sources concerning food and dietary questions. Archaeological excavations of early 15th Century latrines and dumps of refuse thrown in the Lake of Constance revealed a rieh assortment of both animal bones and botanical finds. Vivid paintings of fishmonger's and butcher's stalls, Provision transports and snack bars seem to illustrate everyday life in 15th Century southwest Germany. These paintings stem from a chronicle describing the events during the Council of Constance 1414-1418, written by Ulrich Richental. Thee text gives a wide variety of informations concerning markets, merchandises, prices and wages, it describes picknicks as well as banquets, and teils sundry stories. The municipal archive owns a vast a mount of records, many of which are published: tax rolls, city deeds, wills, Codices of all sorts and court documents. Those written sources allow us to identify owners, landlords or tenants of most houses, they give aecount of taxes, debts and rents to pay. Thus, they allow us, too, to identify the users of the latrines ...
This excellent base of sources could provide us with a great a mount of information about food and its consumers in the 15th Century hitherto
unexploited.
Line defects and (framed) BPS quivers

description: The BPS spectrum of certain N=2 supersymmetric field theories can be determined algebraically by studying the representation theory of BPS quivers. We introduce methods based on BPS quivers to study line defects. The presence of a line defect opens up a new BPS sector: framed BPS states can be bound to the defect. The defect can be geometrically described in terms of laminations on a curve. To a lamination we associate certain elements of the Leavitt path algebra of the BPS quiver and use them to compute the framed BPS spectrum. We also provide an alternative characterization of line defects by introducing framed BPS quivers. Using the theory of (quantum) cluster algebras, we derive an algorithm to compute the framed BPS spectra of new defects from known ones. Line defects are generated from a framed BPS quiver by applying certain sequences of mutation operations. Framed BPS quivers also behave nicely under a set of "cut and join" rules, which can be used to study how N=2 systems with defects couple to produce more complicated ones. We illustrate our formalism with several examples.

Exploring the evolution of color-luminosity parameter $β$ and its effects on parameter estimation

description: It has been found in previous studies that, for the Supernova Legacy Survey three-year (SNLS3) data, there is strong evidence for the redshift-evolution of color-luminosity parameter $β$. In this paper, using three simplest dark energy models ($Λ$CDM, $w$CDM, and CPL), we further explore the evolution of $β$ and its effects on parameter estimation. In addition to the SNLS3 data, we also take into account the Planck distance priors data, as well as the latest galaxy clustering (GC) data extracted from SDSS DR7 and BOSS. We find that, for all the models, adding a parameter of $β$ can reduce $χ^2_{min}$ by $\sim$ 36, indicating that $β_1 = 0$ is ruled out at 6$σ$ confidence levels. In other words, $β$ deviates from a constant at 6$σ$ confidence levels. This conclusion is insensitive to the dark energy models considered, showing the importance of considering the evolution of $β$ in the cosmology-fits. Furthermore, it is found that varying $β$ can significantly change the fitting results of various cosmological parameters: using the SNLS3 data alone, varying $β$ yields a larger $Ω_m$ for the $Λ$CDM model; using the SNLS3+CMB+GC data, varying $β$ yields a larger $Ω_m$ and a smaller $h$ for all the models. Moreover, we find that these results are much closer to those given by the CMB+GC data, compared to the cases of treating $β$ as a constant. This indicates that considering the evolution of $β$ is very helpful for reducing the tension between supernova and other cosmological observations.

description: The memory of the Spanish Civil War and Franco’s dictatorship remain objects of conflict. These conflicts are situated between the Spanish political left and right as well as between a dominant Spanish memory culture and minority memory cultures, such as those of Basque nationalists. These different perspectives in relation to the past are determined by each group’s future aims and are functionalized in order to promote a hegemonic version of the past. This means that the struggle for discursive hegemony cannot be separated from aspects like power, politics, and collective identities. The present contribution investigates the conflict lines between a Spanish memory community and a Basque nationalist community with its subversive memory versions in relation to the dominant narratives of the past.

description: This policy brief explores the potential of local digital twins for data-supported decision making in a time when cities are under pressure to deliver more sustainable policies, optimise service performance and grow local economies, all while keeping people safe, reducing budget spend and managing a wide range of socio economic challenges. DUET (Digital Urban European Twins), a European innovation initiative, transferred the concept of digital twins from an industrial setting to the public sector domain creating a technology called Local Digital Twins (LDT), also known as urban digital twins. Replicating a city's physical assets, processes and systems using data, analytics and machine learning, DUET created virtual replicas of the cities of Athens, Pilsen and the Region of Flanders that automatically updated and changed in real-time as the physical cities themselves changed. This policy brief features a quick-start digital twin maturity model, alongside three key policy recommendations using the experience of DUET to inspire and encourage European cities to start their own digital twin journeys.

description: In den Jahren 2003-2008 wurden im Rahmen der Ausgrabungen im Gebiet des urnenfelderzeitlichen Gräberfelds von Künzing (Lkr. Deggendorf) sechs Bestattungen entdeckt, die äußerst reiche Beigaben enthielten. So fanden sich in Grab A u. a. Teile eines Wagens, Pferdegeschirr aus dem sogenannten thrakokimmerischen Formenkreis und ein Bronzegefäß, in Grab B ein Vollgriffschwert mit Eiseneinlagen und in Grab C eine überdimensionale eiserne Lanzenspitze sowie ein weiteres Bronzekännchen. Eine Tülle aus Grab D kann vermutlich als Trinkhornendbeschlag gedeutet werden. Während Grab E verhältnismäßig ärmlich mit Metallbeigaben ausgestattet war, präsentiert sich Grab F mit weiteren Wagen- und Pferdegeschirr - teilen, einem Vollgriffschwert, einer Sichel und zwei Bronzegefäßen als reichste der Bestattungen. Die Gräber datieren in die späte Urnenfelderzeit. Der enthaltene Leichenbrand deutet in allen Fällen auf männliche Bestattete hin. Zumindest Grab A war zudem von einem Grabgarten umgeben, ähnlich wie zwei weitere, bereits publizierte Bestattungen der Nekropole, in denen ebenfalls Pferdegeschirr geborgen wurde. Im Kontext des Künzinger Gräberfelds wird daher spekuliert, dass in jedem Fall der Bestattete in Grab A eine herausragende Stellung innerhalb der Gemeinschaft innehatte, die mit dem Begriff »Häuptling« bezeich net werden kann.
description: During excavations on the area of the Urnfield period cemetery of Künzing (Landkreis Deggendorf) in 2003-2008 six burials were discovered which contained exceptionally rich burial-goods. For instance, grave A contained among other things parts of a wagon, horse-trappings of the so-called Thracian-Cimmerian sphere and a bronze vessel, while grave B contained a metal-hilted sword with iron inlays and grave C an oversized iron lance-head and a further bronze juglet. A spout from grave D can probably be deemed to
be an end-fitting of a drinking-horn. Whereas grave E was relatively poorly equipped with metal gravefinds, grave F was the richest with further parts of wagon- and horse-trappings, a metal-hilted sword, a sickle and two bronze vessels.
The graves date to the late Urnfield period. In all cases the cremated remains indicate male burials. Additionally, at least grave A was surrounded by a burial-plot, similar to two other burials from the necropolis already published, in which horse-trappings were also found.
In the context of the Künzing cemetery one can thus speculate whether the deceased in grave A certainly held a prominent position within the community, which can be designated as »chieftain« . Translation:

description: The thesis deals with numerical approximation of heat flow in different materials. Besides the well-known solution of the heat flow equation the main subjects are possible approaches for the approximation of convection in both liquids and gasses. These processes are analysed and evaluated with explicit consideration of technical practicability. While doing this physical, mathematical and computer scientific problems were examined. Finally, the outcome led to the programming of a software application, that was used to calculate and discuss some exemplary problems. With the comparison of real measurements and calculated values of similar environments the correctness of the software has been validated.

L'UNIFORMAZIONE DEL DIRITTO CONTRATTUALE EUROPEO E LE TRATTATIVE PRECONTRATTUALI
Creators: name: CRAVETTO, CHIARA
Publisher: name: Universit� degli Studi di Milano
Year: 2012

description: The European scenario has been characterized lately by a systematical harmonization of contract law. The EU Institutions consider the development of a common European contract law as a strategic priority; it could enhance the viability of the EU internal market by facilitating cross-border trade. The thesis analyses the development of the projects that aim at a uniform European contract law, from the specific perspective of liability for breaking off negotiations. After a comparative analysis of the liability for breaking off negotiations in the main European legal systems and in European case law and legislation, the thesis takes into consideration the solution proposed by the instruments for uniform European contract law: the proposal for a Regulation establishing the ?Common European Sales Law? (CESL), the Draft Common Frame of Reference (DCFR), the Principles of European Contract Law (PECL) and the Acquis Principles (ACQP). Attention is paid also to the parallel experience of the international instruments of uniform contract law: the Vienna Convention for international sales law and the Unidroit Principles.

description: Technological progress enables individual cow's temperatures to be measured in real time, using a bolus sensor inserted into the rumen (reticulorumen). However, current cooling systems often work at a constant schedule based on the ambient temperature and not on monitoring the animal itself. This study hypothesized that tailoring the cooling management to the cow's thermal reaction can mitigate heat stress. We propose a dynamic cooling system based on in vivo temperature sensors (boluses). Thus, cooling can be activated as needed and is thus most efficacious. A total of 30 lactating cows were randomly assigned to one of two groups; the groups received two different evaporative cooling regimes. A control group received cooling sessions on a preset time-based schedule, the method commonly used in farms; and an experimental group, which received the sensor-based (SB) cooling regime. Sensor-based was changed weekly according to the cow's reaction, as reflected in the changes in body temperatures from the previous week, as measured by reticulorumen boluses. The two treatment groups of cows had similar milk yields (44.7 kg/d), but those in the experimental group had higher milk fat (3.65 vs 3.43%), higher milk protein (3.23 vs 3.13%), higher energy corrected milk (ECM, 42.84 vs 41.48 kg/d), higher fat corrected milk 4%; (42.76 vs 41.34 kg/d), and shorter heat stress duration (5.03 vs 9.46 h/day) comparing to the control. Dry matter intake was higher in the experimental group. Daily visits to the feed trough were less frequent, with each visit lasting longer. The sensor-based cooling regime may be an effective tool to detect and ease heat stress in high-producing dairy cows during transitional seasons when heat load can become severe in arid and semi-arid zones.

description: We propose a very simple reformulation of General Relativity, which completely sequesters from gravity {\it all} of the vacuum energy from a matter sector, including all loop corrections and renders all contributions from phase transitions automatically small. The idea is to make the dimensional parameters in the matter sector functionals of the 4-volume element of the universe. For them to be nonzero, the universe should be finite in spacetime. If this matter is the Standard Model of particle physics, our mechanism prevents any of its vacuum energy, classical or quantum, from sourcing the curvature of the universe. The mechanism is consistent with the large hierarchy between the Planck scale, electroweak scale and curvature scale, and early universe cosmology, including inflation. Consequences of our proposal are that the vacuum curvature of an old and large universe is not zero, but very small, that $w_{DE} \simeq -1$ is a transient, and that the universe will collapse in the future.

description: Previous work (Schuster & Degen, CogSci 2019) has shown that listeners adapt to two speakers who differ in their use expressions of uncertainty expressions. However, they only looked at a group of listeners in aggregate and did not analyze individual differences. Here, we test to what extent individual differences in working memory control modulate the extent to which individual participants adapt to different speakers. We hypothesize that participants who have better control of their working memory are better at keeping the two speaker's representations apart in memory, resulting in greater adaptation to each speaker.
ITALIAN UNIVERSITIES ACROSS TIME.A LONGITUDINAL ANALYSIS OF THE DIFFUSION OF ITALIAN UNIVERSITIES AND THEIR DETERMINANTS.
Creators: name: GOGLIO, VALENTINA
Publisher: name: Universit� degli Studi di Milano
Year: 2013

description: The dissertation deals with the expansion of the endowment of higher education institutions in Italy and the driving forces behind this process. The focus has been mainly on macro level variables, observing how the aggregate number of universities and satellite universities evolved through time, since the unification of Italy to nowadays. The dissertation has been organized on the basis of two main objects of analysis: the first part deals with the increase of universities operating in the country, while the second part deals with the diffusion of satellite universities. For each of the two objects of analysis we had both a descriptive and analytic purpose: at first we concentrate on describing how the process of founding of new universities (and afterwards, their modern extension, satellite universities) developed through time. On a second stage the focus of attention moved to the analytic level: we investigate under which circumstances a new university or a new satellite university is opened. Which are the features at local and national level that more likely affect the rate of founding of a new university or a satellite campus? We developed a set of hypothesis that mainly refer to the three domains: a) institutional and organizational processes; b) economic factors; c) demand driven processes. With respect to the diffusion of universities, findings from our statistical models suggest that expansion of universities in the last thirty years has been mainly driven by factors that can be associated to the demand for higher education, with a distribution of universities mainly in highly populated areas and with good economic performances. As far as satellite universities are concerned, findings from our model suggest that again the phenomenon may be interpreted as demand-driven, but strongly associated with a tendency to implement imitative processes among peers. Referring to the notion of isomorphism and legitimacy developed by new institutional literature, imitative processes seem to work both between and within satellite universities. Once the new form of organization begins to be accepted and legitimated, a sort of race for following the new ?fashion? spreads among universities. The same occurs among satellite universities that become autonomous universities: once become ?adult? they tend to perpetuate the same scheme that gave them birth. The latter may be identified as a sort of intergenerational imitative process, that could be traced back -although in a variant version- to the case of mimetic isomorphism described in new institutional theory.

description: Recent studies have evidenced that dietary calcium is able to exert a chemoprotective role on normal differentiated intestinal cells, while it behaves as a carcinogenesis promoter on aberrant colonocytes and adenomatous crypts. These different functions can be achieved through the modulation of proliferation and/or differentiation processes, triggered by the increase of the calcium ion concentrations in the intestinal lumen after a meal. Milk represents the major source of calcium in the diet, due to the high availability of the mineral bound to casein and casein phosphopeptides (CPPs). CPPs, derived by in vitro or in vivo casein hydrolysis, are able to bind calcium, blocking the mineral precipitation in the presence of phosphate and /or sulphate salts and to induce a calcium uptake in human intestinal tumor cell lines HT-29 and Caco2 differentiated in vitro toward an enterocityc phenotype. Thus the hypothesis that CPPs could differently affect proliferation and apoptosis in undifferentiated and differentiated HT-29 and Caco2 cells through their binding with calcium ions was here investigated. Results showed that in HT-29 cells CPPs protect differentiated cells from calcium overload toxicity, prevent their apoptosis, favoring proliferation, while in undifferentiated, tumor like, cells they induce apoptosis. The mechanism by which CPPs act in HT-29 cells is mainly the modulation of the voltage operated L-type calcium channels, known to activate calcium entry into the cells under depolarization, a situation occurring after a meal, and to exert a mitogenic effect. The L-type calcium channels have been now recognized to represent one of the two transcellular calcium absorption ways, characterized by the location in the distal ileum and the independence of vitamin D control. In Caco2 cells, CPPs did not significantly affect proliferation, while increase apoptosis in undifferentiated, tumor like, cells. The mechanism by which CPPs act in Caco2 cells is mainly through the TRPV6 channel, known as the main epithelial channel responsible for the transcellular calcium absorption at duodenum level, subject to vitamin D control and with a saturation kinetic for calcium. Taken together these results demonstrate the ability for CPPs, to modulate the two principal transcellular calcium absorption mechanisms. Moreover, through the binding with calcium ions and the stimulated ingression of this mineral in intestinal cells, CPPs can directly modulate the biological activity strictly related to the expression of a normal or cancer phenotype, thus opening the way for a use of CPPs as nutraceutical/functional food.

description: Let G be an inner form of a general linear group over a non-archimedean local field. We prove that the local Langlands correspondence for G preserves depths. We also show that the local Langlands correspondence for inner forms of special linear groups preserves the depths of essentially tame Langlands parameters.
description: The proof of Lemma 3.2 in the first version contained a mistake. In the second version the analysis of depth for inner forms of SL_n was extended and paragraph 2.4 was simplified

description: Nitrous oxide (N2O) is a long-lived greenhouse gas that contributes to global warming. Emissions of N2O mainly stem from agricultural soils. This review highlights the principal factors from peer-reviewed literature affecting N2O emissions from agricultural soils, by grouping the factors into three categories: environmental, management and measurement. Within these categories, each impact factor is explained in detail and its influence on N2O emissions from the soil is summarized. It is also shown how each impact factor influences other impact factors. Process-based simulation models used for estimating N2O emissions are reviewed regarding their ability to consider the impact factors in simulating N2O. The model strengths and weaknesses in simulating N2O emissions from managed soils are summarized. Finally, three selected process-based simulation models (Daily Century (DAYCENT), DeNitrification-DeComposition (DNDC), and Soil and Water Assessment Tool (SWAT)) are discussed that are widely used to simulate N2O emissions from cropping systems. Their ability to simulate N2O emissions is evaluated by describing the model components that are relevant to N2O processes and their representation in the model.

description: The liver macrophage population comprises resident Kupffer cells (KCs) and monocyte-derived macrophages, with distinct pro- or anti-inflammatory properties that affect the severity and course of liver diseases. The mechanisms underlying macrophage differentiation and function in metabolic dysfunction-associated steatotic liver disease and/or steatohepatitis (MASLD/MASH) remain mostly unknown. Using single-cell RNA sequencing and fate mapping of hepatic macrophage subpopulations, we unraveled the temporal and spatial dynamics of distinct monocyte and monocyte-derived macrophage subsets in MASH. We revealed a crucial role for the Notch-RBPJ signaling pathway in controlling the monocyte-to-macrophage transition, with Rbpj deficiency blunting inflammatory macrophages and monocyte-derived KCs differentiation and conversely promoting the emergence of protective Ly6Clo monocytes. Mechanistically, Rbpj-deficiency promoted lipid uptake driven by elevated CD36 expression in Ly6Clo monocytes, enhancing their protective interactions with endothelial cells. Our findings uncover the crucial role of Notch-RBPJ signaling in monocyte-to-macrophage transition and will aid the design of therapeutic strategies for MASH treatment.

description: The Rosenblatt process was obtained by Taqqu (1975) from convergence in distribution of partial sums of strongly dependent random variables. In this paper we give a particle picture approach to the Rosenblatt process with the help of intersection local time and white noise analysis, and discuss measuring its long range dependence by means of a number called dependence exponent.

description: We present a new Fermi gas formalism for the ABJ matrix model. This formulation identifies the effect of the fractional M2-brane in the ABJ matrix model as that of a composite Wilson loop operator in the corresponding ABJM matrix model. Using this formalism, we study the phase part of the ABJ partition function numerically and find a simple expression for it. We further compute a few exact values of the partition function at some coupling constants. Fitting these exact values against the expected form of the grand potential, we can determine the grand potential with exact coefficients. The results at various coupling constants enable us to conjecture an explicit form of the grand potential for general coupling constants. The part of the conjectured grand potential from the perturbative sum, worldsheet instantons and bound states is regarded as a natural generalization of that in the ABJM matrix model, though the membrane instanton part contains a new contribution.

FIRST-PRINCIPLES INVESTIGATION OF THE ELECTRONIC AND TRANSPORT PROPERTIES OF CARBON ATOM WIRES

description: The last years have witnessed an ever increasing interest in the field of molecular electronics, in which molecules connected with two or more electrodes are used as main building blocks to fabricate the components of integrated circuits. The achievement of high performance interconnects is one of the key step for the realization of such devices. In this context, conjugated carbon wires are the most promising candidates to this role due to their structural stability and their experimental feasibility. In particular we investigated the transport properties of systems where a freestanding conjugated carbon chain is contacted with two electrodes in order achieve a two-terminal device. Although some important issues had already been investigated in this field when starting this project, information were very scattered and a well-rounded perspective of the key aspects affecting the electron transport was missing. This thesis represents one attempt to fill this gap first in the case of Ag-chain-Ag systems and then for graphene-chain-graphene devices. Specifically we focused on the role that the chain-electrode junction plays in determining the characteristics of such systems, finding that the contact geometry strongly affect the transport properties. In fact, for Ag-chain-Ag systems, qualitative different transport properties have been found depending on the adsorption site on the silver surface, while results showed only a weak dependence on the chain length. Moreover we observed that those results can be extended to "tip-like" contacts, mimicking a more realistic electrodic surface. As opposite, linking atoms such as sulfur or silicon strongly influence the conductance. We further demonstrated that the vibrational motion of the atoms has negligible effects on the transport properties for a very large range of temperature. Finally we also critically assessed the reliability of our results using the optical properties of the gas-phase molecules to benchmark the adopted setup. The results obtained for graphene-chain-graphene devices confirmed that the junction plays a central role in determining the strength of the electrode-chain coupling, and in turn, the conductance. We first analyzed in details the transport properties of single chains connected to ideal electrodes, investigating their geometrical and electronic structure in order to establish a connection with their transport properties. Furthermore, at odds with the above mentioned metal-C-metal systems, we found that "tip-like" junctions here have dramatic effects on the transport properties. More importantly, we investigated the possibility to observe quantum interference, chemical gating and conductance switching behaviors in such systems.

description: In this paper, we study the formal solution space of a nonlinear PDE in a fiber bundle. To this end, we start with foundational material and introduce the notion of a pfd structure to build up a new concept of profinite dimensional manifolds. We show that the infinite jet space of the fiber bundle is a profinite dimensional manifold in a natural way. The formal solution space of the nonlinear PDE then is a subspace of this jet space, and inherits from it the structure of a profinite dimensional manifold, if the PDE is formally integrable. We apply our concept to scalar PDEs and prove a new criterion for formal integrability of such PDEs. In particular, this result entails that the Euler-Lagrange equation of a relativistic scalar field with a polynomial self-interaction is formally integrable.

description: We study the effect of disorder in a holographic superconductor by introducing a quasi-periodic chemical potential. When the condensation of the superconductor is sufficiently small compared with the strength of disorder, we find that there exists a discontinuous phase transition from superconducting state to normal state with increasing disorder strength. For relatively large condensation, we find that disorder suppress but not completely destroy superconductivity. This model may provide a holographic realization of Anderson Localization in two-dimensional superconductor.
