description: Five dimensional black hole solutions that describe the QCD crossover transition seen in $(2+1)$-flavor lattice QCD calculations at zero and nonzero baryon densities are used to obtain predictions for the baryon susceptibility, baryon conductivity, baryon diffusion constant, and thermal conductivity of the strongly coupled quark-gluon plasma in the range of temperatures $130\,\textrm{MeV}\le T\le 300\,\textrm{MeV}$ and baryon chemical potentials $0\le μ_B \le 400\,\textrm{MeV}$. Diffusive transport is predicted to be suppressed in this region of the QCD phase diagram, which is consistent with the existence of a critical end point at larger baryon densities. We also calculate the fourth-order baryon susceptibility at zero baryon chemical potential and find quantitative agreement with recent lattice results. The baryon transport coefficients computed in this paper can be readily implemented in state-of-the-art hydrodynamic codes used to investigate the dense QGP currently produced at RHIC's low energy beam scan.

description: In the present work, we study celestial correlators of light transformed gluon operators at tree level. We also discuss the transformation of light transformed operators under the action of 4D translations. The two, three and four-point functions arising from MHV amplitudes in terms of light transformed operators satisfy translation invariance constraints, are non-distributional and contain ordinary CFT power law terms. There is a new channel dependent term in the three point function. We show that the three-point light transformed correlation function is conformally covariant after contributions from all the three channels are added. We also study the OPE limit of the different channels of the three-point function in an attempt to construct a map between the OPE in the Mellin basis and that in the light transformed one.

description: To understand what drives the concentration of CO2 in the atmosphere, it is crucial to understand the complexity of the underlying CO2 fluxes, and this first volume of FLUXES provides this information. FLUXES is a new publication designed to inform the interested audience of key scientific aspects of the European greenhouse gas budget. FLUXES will be published every summer to support the European Union in their preparation for the upcoming UNFCCC Conference of Parties and to guide European climate action in general.
Greenhouse gas fluxes vary from year to year, that’s natural. However, Europe and the world are currently facing multiple hazards (heatwaves, droughts, fires, floods...) that are driven by climate change and – among many other damages – are altering greenhouse gas fluxes. These feedbacks put particularly natural CO2 sinks at risk but it requires monitoring of over long times to clearly identify and understand them. FLUXES, the European Greenhouse Gas Bulletin aims to transfer most recent scientific findings in order to distinguish occasional phenomena from long-term trends. It will focus on observations as the basis of a scientific value chain towards climate services and policy support.

description: We study core-periphery structure in networks using inference methods based on a flexible network model that allows for traditional onion-like cores within cores, but also for hierarchical tree-like structures and more general non-nested types of structure. We propose an efficient Monte Carlo scheme for fitting the model to observed networks and report results for a selection of real-world data sets. Among other things, we observe an empirical distinction between networks showing traditional core-periphery structure with a dense core weakly connected to a sparse periphery, and an alternative structure in which the core is strongly connected both within itself and to the periphery. Networks vary in whether they are better represented by one type of structure or the other. We also observe structures that are a hybrid between core-periphery structure and community structure, in which networks have a set of non-overlapping cores that correspond roughly to communities, surrounded by a single undifferentiated periphery. Computer code implementing our methods is available.

Quantum Simulations in Effective Model Spaces (I): Hamiltonian Learning-VQE using Digital Quantum Computers and Application to the Lipkin-Meshkov-Glick Model

description: The utility of effective model spaces in quantum simulations of non-relativistic quantum many-body systems is explored in the context of the Lipkin-Meshkov-Glick model of interacting fermions. We introduce an iterative hybrid-classical-quantum algorithm, Hamiltonian learning variational quantum eigensolver (HL-VQE), that simultaneously optimizes an effective Hamiltonian, thereby rearranging entanglement into the effective model space, and the associated ground-state wavefunction. HL-VQE is found to provide an exponential improvement in Lipkin-Meshkov-Glick model calculations, compared to a naive truncation without Hamiltonian learning, throughout a significant fraction of the Hilbert space. Quantum simulations are performed to demonstrate the HL-VQE algorithm, using an efficient mapping where the number of qubits scales with the $\log$ of the size of the effective model space, rather than the particle number, allowing for the description of large systems with small quantum circuits. Implementations on IBM's QExperience quantum computers and simulators for 1- and 2-qubit effective model spaces are shown to provide accurate and precise results, reproducing classical predictions. This work constitutes a step in the development of entanglement-driven quantum algorithms for the description of nuclear systems, that leverages the potential of noisy intermediate-scale quantum (NISQ) devices.

description: We have observed a significant enhancement in the energy deposition by $25$--$100~\mathrm{GeV}$ photons in a $1~\mathrm{cm}$ thick tungsten crystal oriented along its $\langle 111 \rangle$ lattice axes. At $100~\mathrm{GeV}$, this enhancement, with respect to the value observed without axial alignment, is more than twofold. This effect, together with the measured huge increase in secondary particle generation is ascribed to the acceleration of the electromagnetic shower development by the strong axial electric field. The experimental results have been critically compared with a newly developed Monte Carlo adapted for use with crystals of multi-$X_0$ thickness. The results presented in this paper may prove to be of significant interest for the development of high-performance photon absorbers and highly compact electromagnetic calorimeters and beam dumps for use at the energy and intensity frontiers.

From this analytical result we also provide numerical constraints for a generation of vector-like quarks and vector-like leptons.

title: In vitro pharmacological characterisation of the role of ACKR3 on CXCR4-dependent and -independent function
Creators: name: Capoferri, Davide
Publisher: name: University of Glasgow
Year: 2020

description: CXC-motif chemokine Receptor 4 (CXCR4) and Atypical ChemoKine Receptor 3 (ACKR3) are two 7-transmembrane domain receptors often studied together due to their common ligand CXC-motif chemokine Ligand 12 (CXCL12) and the implication of said ligand in several pathophysiological processes, cancer growth and metastasis formation among them. This thesis project started with the aim of clarifying the interaction between these receptors and their second messengers, namely the different G proteins and arrestins, upon stimulation with different ligands, establishing a relationship between them in order to adjust the model of biased agonism to this system. Chapter 3 indeed gathers the efforts made to design and test molecular sensors that might have helped to understand whether the two receptors, alone or combined, give different types of signal in relation to differences in their expression or to different ligands. Even though several approaches were followed, this goal was not reached in full. The products generated from this first big molecular part had been propedeutical to the characterization of a new class of nanobodies against CXCR4 and ACKR3 synthesized by a project partner company. Further, the focus narrowed on ACKR3, whose role on CXCR4-dependent cell migration was investigated in vitro through CRISPR. Indeed the first part of Chapter 4 describes that the lack of human ACKR3 in Jurkat cells showed a significant reduction in the amount of cells migrated towards CXCL12, indicating that ACKR3 has an indirect role in CXCR4-dependent cell migration. In the second part tumor growth dependent of ACKR3 alone was investigated: the knock-out of murine ACKR3 in LLC cells demonstrated that ACKR3 has a positive role in tumor growth regardless the expression of CXCR4. Finally, the project headed towards the characterization of a very discussed interaction, namely that between human ACKR3 and human Adrenomedullin. Chapter 5 was dedicated to this topic, and several approaches led to the conclusions that this interaction exists, is slightly less potent than that with canonical chemokine ligands, but has a therapeutic potential still undiscovered. The results and the models build a strong body of evidence that converge on the aforementioned conclusions, and constitute a cue to consider this interaction worthy of further consideration.

Improved Delayed Detached Eddy Simulation with Reynolds-Stress Background Modeling

description: A novel variant of Improved Delayed Detached-Eddy Simulation based on a differential Reynolds-stress background model is presented. The approach aims to combine the advantages of anisotropy-resolving Reynolds-stress closures in the modelled RANS regions with consistent LES and wall-modelled LES behaviour in the resolved flow regions. In computations of decaying isotropic turbulence with a low-dissipative flow solver it is shown that a straightforward hybridised Reynolds-stress model provides insufficient turbulent dissipation as sub-grid closure in the LES regions and is therefore locally replaced by scalar viscosity modelling. Simulations of periodic channel flows at different Reynolds numbers and grid resolutions are used to calibrate and validate the wall-modelled LES branch of the new model. A final application in embedded wall-modelled LES of a flat-plate boundary layer is widely consistent with results using the SST-RANS background model, but shows some deviations from the Coles-Fernholz skin-friction correlation. In this regard, initial sensitivity studies indicate possible adverse effects due to the synthetic-turbulence approach used in these simulations.

description: The glycolytic enzyme glyceraldehyde-3-phosphate dehydrogenase (GAPDH) signals during cellular stress via several post-translational modifications that change its folding properties, protein-protein interactions and sub-cellular localization. We examined GAPDH properties in acute mouse liver injury due to ethanol and/or acetaminophen (APAP) treatment. Synergistic robust and time-dependent nuclear accumulation and aggregation of GAPDH were observed only in combined, but not individual, ethanol/APAP treatments. The small molecule GAPDH-targeting compound TCH346 partially attenuated liver damage possibly via mitochondrial mechanisms, and independent of nuclear accumulation and aggregation of GAPDH. These findings provide a novel potential mechanism for hepatotoxicity caused by combined alcohol and acetaminophen exposure.

description: Changing and faceted, those in which we live are Trembling Landscapes, often bare of those values that characterized them so distinctly a time. The European Landscape Convention was born with the ethical mission to ensure people a quality landscape that contributes to wellbeing, to satisfy the desires of the development of the communities and reinforce the European identity. This principle today needs new tools to determine its effectiveness in the territory without risk of adding complexity to the dense hierarchy of existing planning instruments. Facing with this dual demand for recovery of sense of place through easy means, the landscape quality objectives can provide an innovative response that is laid out according to three parameters able to describe the current position of a landscape in the perceptual space of the population: Magnitude, Direction and Way.

description: The existence of non-zero neutrino masses points to the likely existence of multiple SM neutral fermions. When such states are heavy enough that they cannot be produced in oscillations, they are referred to as Heavy Neutral Leptons (HNLs). In this white paper we discuss the present experimental status of HNLs including colliders, beta decay, accelerators, as well as astrophysical and cosmological impacts. We discuss the importance of continuing to search for HNLs, and its potential impact on our understanding on key fundamental questions, and additionally we outline the future prospects for next-generation future experiments or upcoming accelerator run scenarios.

description: Telomeres of nuclear chromosomes are usually composed of an array of tandemly repeated sequences that are recognized by specific Myb domain containing DNA-binding proteins (telomere-binding proteins, TBPs). Whereas in many eukaryotes the length and sequence of the telomeric repeat is relatively conserved, telomeric sequences in various yeasts are highly variable. Schizosaccharomyces pombe provides an excellent model for investigation of co-evolution of telomeres and TBPs. First, telomeric repeats of S. pombe differ from the canonical mammalian type TTAGGG sequence. Second, S. pombe telomeres exhibit a high degree of intratelomeric heterogeneity. Third, S. pombe contains all types of known TBPs (Rap1p [a version unable to bind DNA], Tay1p/Teb1p, and Taz1p) that are employed by various yeast species to protect their telomeres. With the aim of reconstructing evolutionary paths leading to a separation of roles between Teb1p and Taz1p, we performed a comparative analysis of the DNA-binding properties of both proteins using combined qualitative and quantitative biochemical approaches. Visualization of DNA-protein complexes by electron microscopy revealed qualitative differences of binding of Teb1p and Taz1p to mammalian type and fission yeast telomeres. Fluorescence anisotropy analysis quantified the binding affinity of Teb1p and Taz1p to three different DNA substrates. Additionally, we carried out electrophoretic mobility shift assays using mammalian type telomeres and native substrates (telomeric repeats, histone-box sequences) as well as their mutated versions. We observed relative DNA sequence binding flexibility of Taz1p and higher binding stringency of Teb1p when both proteins were compared directly to each other. These properties may have driven replacement of Teb1p by Taz1p as the TBP in fission yeast.

description: The discovery of correlated phases in twisted moiré superlattices accelerated the search for low-dimensional materials with exotic properties. A promising approach uses engineered substrates to strain the material. However, designing substrates for tailored properties is hindered by the incomplete understanding of the relationship between substrate's shapes and electronic properties of the deposited materials. By analyzing effective models of graphene under periodic deformations with generic crystalline profiles, we identify strong $C_{2z}$ symmetry breaking as the critical substrate geometric feature for emerging energy gaps and quasi-flat bands. We find continuous strain profiles producing connected pseudo-magnetic field landscapes are important for band topology. We show that the resultant electronic and topological properties from a substrate can be controlled with circularly polarized light, which also offers unique signatures for identifying the band topology imprinted by strain. Our results can guide experiments on strain engineering for exploring interesting transport and topological phenomena.

title: Artificial neural networks for scattered light imaging

Publisher: name: University of Glasgow
Year: 2020
Subjects: subject: Optics, computational imaging, artificial neural networks, scattered light, multimode fibres.

description: Image formation is one of the most important aspect of our everyday life. Conventional optical Imaging (and Sensing) exploits light, reaching the detection system from a target or a scene of interest, mainly unscattered. However, there are many practical situations in which unscattered light may be undetectable, insufficient or mispresented. Nonetheless, if the considered system allows it, it could be still possible to exploit scattered light in order to extract relevant information. Problems arise from the fact that, in these cases, light propagation may undergo severe alterations, thus leading to challenging, and sometimes ill- posed, problems. In this thesis, two main scenarios involving scattered light are studied and addressed by means of artificial neural networks. Over the last period, these powerful data-driven algorithms have been extensively employed in many scientific contexts for their ability to solve even complex problems implicitly. Precisely this characteristic is exploited, in the present work, in a non-line- of-sight scenario in order to simultaneously locate and identify people hidden behind a corner. Moreover, a complex-valued neural network algorithm is implemented and applied to the problem of transmission of images through a multimode fibre, demonstrating high-speed and high-resolution image restoration even without the need for any phase measurements. Finally, due to its formulation based on the physics of multimode fibres, a direct comparison is proposed between the same algorithm and a more standard approach.
Come “produrre suolo” nelle aree periurbane? Politiche agrourbane del piano paesaggistico regionale della Puglia alla scala locale
Creators: name: Mininni, Mariavaleria

description: The landscape vision of the Puglia Landscape Plan acts as a driving force for matters regarding sustainability which are included in the regional guidelines. On the one hand it helps to support activities which are already underway such as: urban regeneration and guidelines for new general and operational urban plans starting with the combined agro-environmental and multifunctional regeneration of suburbs and nearby areas of countryside. The city-countryside pact is one of five territorial projects regarding regional landscape which collectively represent the active safeguarding proposals and development prospects put forward by the regional landscape Plan and represent part of an incredible challenge for the future of the apulian landscape. The pact is based on an agro-urban vision in which agriculture must be able to integrate with the town and its sprawling-widespread nature. According to this view, agriculture is not merely limited to the production of foodstuffs and the safeguarding of the environment. Indeed, it also assumes the role of a living environment which meets the post-rural demand for both countryside and a tamed form of nature. In this context, thanks to the remuneration which comes from the production and provision of public goods and services through the concepts of multifunctionality (agricultural services which do not concern food stuffs) and conditionalities (the agro-environmental services provided by agriculture and quality of life), periurban agriculture assumes a key role.

Migration

description: Migration ist ein weltweit aktuelles und wichtiges Thema. Auch für die Rapanui, die am Rande des polynesischen Dreiecks mitten im Pazifik auf Rapa Nui, besser bekannt als die Osterinsel, leben. Basierend auf einer ethnografischen Feldforschung auf Rapa Nui untersucht diese Studie die Migrationserfahrungen der Rapanui und deren Auswirkungen auf ihre Identität. Besonders die Migration zu Bildungs- und Arbeitszwecken steht dabei im Fokus, genauso wie die Rückkehr auf die Insel. Junge Rapanui oder sogenannte Mestizos (wörtlich übersetzt Mischlinge, Mestizen), Kinder mit einem Rapanui und einem einer anderen Nationalität angehörigen Elternteil, wachsen im Kontext politischen, kulturellen und gesellschaftlichen Wandels auf. Die Identität der Rapanui bewegt sich innerhalb dieser verschiedenen Kontexte. Besonders die kulturelle und ethnische Identität sowie die Sprache Rapanui spielen eine wichtige Rolle für ihre Identitätskonstruktionen und ihr Zugehörigkeitsgefühl. Es wird argumentiert, dass während der Migration und nach der Rückkehr auf die Insel Abgrenzungs- sowie Aushandlungsprozesse stattfinden und, dass Migrationserfahrungen die Identität der Rapanui beeinflussen und zu Identitätsverschiebungen oder -verstärkungen führen können, wobei individuelle und kontextuelle Umstände berücksichtigt werden müssen.
description: Migration is a current and important topic worldwide. As well for the Rapanui who live on the edge of the Polynesian triangle in the middle of the Pacific on Rapa Nui, better known as Easter Island. Based on an ethnographic fieldwork on Rapa Nui, this study examines the migration experiences of Rapanui and their impact on their identity. In particular, the focus is lying on migration for education and work purposes as well as the return to the island. Young Rapanui or so-called mestizos (literally translated as person of mixed parentage, mestizos), children with a Rapanui and a parent of another nationality, grow up in the context of political, cultural and social change. The identity of Rapanui moves within these various contexts. Especially the cultural and ethnic identity as well as the language Rapanui play an important role for their identity constructions and sense of belonging. It is argued that demarcation and negotiation processes take place during migration and after returning to the island, and that migration experiences can affect the identity of the Rapanui and can lead to identity shifts or reinforcements whereupon individual and contextual circumstances have to be taken into account.

description: We investigate the pc-scale kinematics and kpc-scale radio morphology of the quasar PG 1302-102, which may harbour a sub-pc separation supermassive binary black hole system at its centre as inferred from optical variability. High-resolution radio interferometric measurements obtained with the Very Long Baseline Array (VLBA) in the Monitoring Of Jets in Active galactic nuclei with VLBA Experiments (MOJAVE) programme at 15 GHz at 20 epochs spanning 17 years were analysed to investigate the pc-scale radio structure. Archival observations with the Very Large Array (VLA) at 1.4 GHz and 5 GHz were obtained to study the kpc-scale morphology. We find that the pc-scale jet is inclined within ~2.2 deg to the line of sight and has a half-opening angle of about 0.2 deg. The parameters derived from the pc-scale radio jet are qualitatively consistent with those obtained from the analysis of the optical light curve of PG 1302-102. We obtain at least 0.08 for the mass ratio of the two black holes in the system. We find some indication for a helical jet structure on kpc-scale, but the directions of the inner and the extended radio jets are significantly different, obstructing a straightforward connection of the pc- and kpc-scale jets within the binary scenario.

description: The long-term optical and infrared color variability of blazars has been investigated with the SMARTS monitoring data. The sample in this study consists of 49 flat spectrum radio quasars and 22 BL Lac objects. The fractional variability amplitudes of each source have been calculated in both optical R band and infrared J band. Overall, the variability amplitudes of FSRQs are larger than those of BL Lac objects. The results also suggest that the variability amplitude of most FSRQs is larger at lower energy band (J band) than at higher one (R band), while the variability amplitude of BL Lacs are larger at higher energy band. Two types of blazars both display color variation along with the variability in brightness. However, they show different variation behaviors in general. With the whole data set, 35 FSRQs exhibit redder-when-brighter trends, and 11 FSRQs exhibit opposite trends; 11 BL Lacs follow bluer-when-brighter trends, and 7 BL Lacs follow opposite trends. The examination in detail shows that there are 10 blazars showing redder-when-brighter trend in their low state, and bluer-when-brighter or stable-when-brighter trends in their high state. Some more complicated color behaviors have also been detected in several blazars. The non-thermal jet emission and the thermal emission from the accretion disc are employed to explain the observed color behaviors.

description: Pervasive computing promotes the integration of smart devices in our living spaces to develop services providing assistance to people. Such smart devices are increasingly relying on cloud-based Machine Learning, which raises questions in terms of security (data privacy), reliance (latency), and communication costs. In this context, Federated Learning (FL) has been introduced as a new machine learning paradigm enhancing the use of local devices. At the server level, FL aggregates models learned locally on distributed clients to obtain a more general model. In this way, no private data is sent over the network, and the communication cost is reduced. Unfortunately, however, the most popular federated learning algorithms have been shown not to be adapted to some highly heterogeneous pervasive computing environments. In this paper, we propose a new FL algorithm, termed FedDist, which can modify models (here, deep neural network) during training by identifying dissimilarities between neurons among the clients. This permits to account for clients' specificity without impairing generalization. FedDist evaluated with three state-of-the-art federated learning algorithms on three large heterogeneous mobile Human Activity Recognition datasets. Results have shown the ability of FedDist to adapt to heterogeneous data and the capability of FL to deal with asynchronous situations.

description: Over the last few years, a new mode for imaging in the scanning transmission electron microscope (STEM) has gained attention as it permits the direct visualization of sample conductivity and electrical connectivity. When the electron beam (e-beam) is focused on the sample in the STEM, secondary electrons (SEs) are generated. If the sample is conductive and electrically connected to an amplifier, the SE current can be measured as a function of the e-beam position. This scenario is similar to the better-known scanning electron microscopy (SEM)-based technique, electron beam induced current (EBIC) imaging except the signal in STEM is generated by the emission of SEs, hence the name SEEBIC, and in this case the current flows in the opposite direction. Here, we provide a brief review of recent work in this area, examine the various contrast generation mechanisms associated with SEEBIC, and illustrate its use for the characterization of graphene nanoribbon devices.

description: Abstract Residential segregation is a long term challenge the world over with daunting consequences that leave the city unable to attain its full potentials. In Jos, residential segregation has assumed a worrisome and unfortunate trend that has affected where people live, work, do business and recreate. This paper assessed residential segregation and implications on physical planning and development in Jos North Local Government Area. The study selected six (6) wards out of the fourteen (14) in the LGA. Two (2) neighborhoods each dominated by Christians, Muslims or mixed were randomly selected and 304 respondents drawn from the 6 neighborhoods with bias for people that have lived in Jos since 2001 (when the first major ethno-religious violent conflict occurred) who could relate with conflict experiences resulting in residential segregation and the implications on physical planning and development. The study reveals that residential segregation existed since the colonial era but has recently been sustained by the sectarian crises which began in 2001. More than 81% of the respondents indicated that segregated neighborhoods are directly related to the ripple effects of the ethno-religious violence, resulting in residential neighborhoods that are now ethno-religious territories and enclaves, some of which have become beehives of terror and criminal hide outs and activities. Further implications include accelerated increase in demand and price of land, poor and inaccessible road network, minimal infrastructure and service provision, increase housing demand, illegal and uncontrolled housing development leading to the emergence of new slums and informal settlements along the fringes of the city some of which are inaccessible to public officials, city managers and service providers. The range of implications are common across all segregated neighborhoods and require urgent interventions to enhance effective and efficient physical planning and sustainable development in all facets. Urgent physical planning intervention and spatial framework to address development challenges would help to largely reduce uncontrolled residential segregation and its implications through partnership between residents, government and development oriented organizations.

description: Quantum magnets provide a powerful platform to explore complex quantum many-body phenomena. One example is triplon excitations, exotic many-body modes emerging from deconfined singlet-triplet transitions with no single particle analog. Triplons are challenging to observe in conventional materials, as the energy scales of singlet-triplet transitions are associated with Hund's energy and are dramatically larger than the typical bandwidth of spin fluctuations. We engineer a minimal quantum magnet from organic molecules and demonstrate the emergence of dispersive triplon modes in one- and two-dimensional assemblies probed with scanning tunneling microscopy and spectroscopy. We show the variable bandwidth of triplon excitations in these two different geometries. Our results provide the first demonstration of dispersive triplon excitations from a real-space measurement, suggesting their potential engineering to realize exotic many-body phenomena in quantum magnets without breaking time-reversal symmetry.

description: We describe a general framework for notions of commutativity based on enriched category theory. We extend Eilenberg and Kelly's tensor product for categories enriched over a symmetric monoidal base to a tensor product for categories enriched over a normal duoidal category; using this, we re-find notions such as the commutativity of a finitary algebraic theory or a strong monad, the commuting tensor product of two theories, and the Boardman-Vogt tensor product of symmetric operads.
