description: Rydberg atomic sensors and receivers have enabled sensitive and traceable measurements of RF fields at a wide range of frequencies. Here we demonstrate the detection of electric field amplitude in the extremely high frequency (EHF) band, at $131\ \mathrm{GHz}$. In our approach we propagate the EHF field in a beam, with control over its direction and polarization at the detector using photonic waveplates. This way, we take advantage of the highest detection sensitivity, registered for collinear propagation and circular polarization. To exhibit the potential for applications in this kind of Rydberg-atom based detection, we perform test measurements on the EHF field emitted from an on-chip radar, planned to be used in automotive industry as a vital sign detector. Our work elucidates practical applications of Rydberg-atom media as well as photonic metamaterial elements.

Subjects: subject: Mechanical Engineering

description: In this study covering various sectors of the continent, the role of service quality dimensions in improving customer satisfaction in Africa was examined. Five variables–reliability, assurance, tangibility, empathy and responsiveness–have generally been used to assess service quality in literature. All of these variables were checked and evaluated their effect on customer satisfaction. Nonetheless, the main aim of this analysis was to rate each of these five variables based on their customer satisfaction level of significance. First, based on empirical analysis, this study found that all five dimensions of quality of service are important predictors of customer satisfaction. Yet reliability is the most powerful indicator of customer satisfaction in Africa, closely followed by assurance, in order to be of significance. Next on the list is third responsiveness, and fourth tangibility. Third, empathy ranked fifth on customer satisfaction in order of significance. The study recommends that significant considerations be given to all five dimensions of service quality by organizations in Africa with respect to their level of customer satisfaction significance.

Can Channels be Fully Inferred Between Two Antenna Panels?

description: This letter considers a two-panel massive multiple-input multiple-output (MIMO) communication system, where the base station (BS) is equipped with two antenna panels that may use different frequency bands for communication. By exploiting the geometric relationships between antenna panels, efficient channel inference methods across antenna panels are proposed to reduce the overhead of real-time channel estimation. Four scenarios are considered, namely far-field free-space, near-field free-space, multi-path sharing far-field scatterers, and multi-path sharing near-field scatterers. For both far-field and near-field free-space scenarios, we show that the channel of one panel can be fully inferred from that of the other panel, as long as the multi-path components (MPCs) composing the channel can be resolved. On the other hand, for the multi-path scenarios sharing far-field or near-field scatterers, only the angles or range of angles of the MPCs can be inferred, respectively. Simulation results based on commercial 3D ray-tracing software are presented to validate our developed channel inference techniques.

Play a tumour in the head and air pollution : a translation of Dušan Jovanović’s Igrajte tumor v glavi in onesnaženje zraka
Creators: name: Soule, Lesley Wade
Publisher: name: University of British Columbia
Year: 2010

description: Play a Tumour in the Head and Air Pollution is a drama in three acts written by the Yugoslavian playwright and director Dušan Jovanović’s in 1971-1972. The original version is in Slovene, the language of Yugoslavia's northernmost province, Slovenia, where the dramatist (a Serb by birth) has lived since the age of twelve. Play a Tumour... was first produced in Gelje, Slovenia, by the well-known experimental director Ljubisar Ristic. Later it was also staged in Belgrade. The play was written to direct attention at what Jovanovic regards as the "mortality" at work in society, and uses theatrical performance itself as a metaphor for the structures of social and political life. The action centers on a revolt by the avant-garde members of the Slavia Theatre company, who eject the other actors, barricade themselves inside the theatre and carry on bizarre experiments aimed at overcoming the fatal banality of conventional theatre and everyday life. The play's outer action and inner psycho-political life are subtly interwoven. Although rich in stage action, the play focusses strongly on problems of the nature of language and thus presents interesting challenges to the translator. This translation is intended to provide the English-speaking reader with a significant, example of the concerns which engage a leading playwright in the cultural and political milieu of contemporary Slovenia. It is therefore a complete and faithful rendering of the original, rather than a free adaptation intended for staging before Western audiences. The play's first act takes place in a realistically presented newspaper office, where the lock-out at the Slavia Theatre is discussed and attempts are made to find out what is going on there. The second and third acts, set on the stage of the theatre itself, show the activities and experiments of the "rebels" and their interaction with two investigator a policeman and a journalist, sent in to discover what they are up to. The play's striking ending involves not only a metaphorical "crossing over into death" by the two investigators but also a confrontation of the audience with the basic mystery-problem of socio-theatrical reality.

description: Neural networks have recently become the dominant approach to sound separation. Their good performance relies on large datasets of isolated recordings. For speech and music, isolated single channel data are readily available; however the same does not hold in the multi-channel case, and with most other sound classes. Multi-channel methods have the potential to outperform single channel approaches as they can exploit both spatial and spectral features, but the lack of training data remains a challenge. We propose unsupervised improved minimum variation distortionless response (UIMVDR), which enables multi-channel separation to leverage in-the-wild single-channel data through unsupervised training and beamforming. Results show that UIMVDR generalizes well and improves separation performance compared to supervised models, particularly in cases with limited supervised data. By using data available online, it also reduces the effort required to gather data for multi-channel approaches.

description: The logarithmic-normal (lognormal) distribution is one of the most frequently observed distributions in nature and describes a large number of physical, biological and even sociological phenomena. The origin of this distribution is therefore of broad interest but a general derivation from basic principles is still lacking. Using random nucleation and growth to describe crystallization processes we derive the time development of grain size distributions. Our derivation provides, for the first time, an analytical expression of the size distribution in the form of a lognormal type distribution. We apply our results to the grain size distribution of solid phase crystallized Si-films.

Measurement of global polarization of $Λ$ hyperons in Au+Au $\sqrt{s_{\mathrm{NN}}}$ = 7.2 GeV fixed target collisions at RHIC-STAR experiment

description: In non-central nuclear collisions, the created matter should exhibit strong vorticity, which induces spin polarization. Global polarization is a good tool to investigate the dynamics of the system. Global polarization of $Λ$ and $\barΛ$ hyperons has been measured at $\sqrt{s_{\mathrm{NN}}}$ = 2.4 GeV - 5.02 TeV in various experiments. We have measured the global polarization of $Λ$ hyperons in Au+Au collisions with fixed-target configuration at $\sqrt{s_{\mathrm{NN}}}$ = 7.2 GeV at RHIC-STAR experiment. The non-zero signal is observed and it follows the global trend of $Λ$ global polarization that increases towards lower collision energies. The global polarization is larger in more peripheral collisions but it does not show any significant rapidity dependence as well as transverse momentum dependence within uncertainties.

Broad Line Emission in Low-Metallicity Blue Compact Dwarf Galaxies: Evidence for Stellar Wind, Supernova and Possible AGN Activity

description: We present spectra of a large sample of low-metallicity blue compact dwarf galaxies which exhibit broad components in their strong emission lines, mainly in Hbeta, [O III]4959, 5007 and Halpha. Twenty-three spectra have been obtained with the MMT, 14 of which show broad emission. The remaining 21 spectra with broad emission have been selected from the Data Release 5 of the Sloan Digital Sky Survey. The most plausible origin of broad line emission is the evolution of massive stars and their interaction with the circumstellar and interstellar medium. The broad emission with the lowest H$α$ luminosities (10^36 - 10^39 erg/s) is likely produced in circumstellar envelopes around hot Ofp/WN9 and/or LBV stars. The broad emission with the highest Halpha luminosities (10^40 - 10^42 erg/s) probably arises from type IIp or type IIn supernovae (SNe). It can also come from active galactic nuclei (AGN) containing intermediate-mass black holes, although we find no strong evidence for hard non-thermal radiation in our sample galaxies. The oxygen abundance in the host galaxies with SN candidates is low and varies in the range 12 + log O/H = 7.36 - 8.31. However, type IIn SN / AGN candidates are found only in galaxies with 12 + log O/H < 7.99. Spectroscopic monitoring of these type IIn SN / AGN candidates over a time scale of several years is necessary to distinguish between the two possibilities.

description: Productive districts introduce a principle of bio-uniqueness between the urban and productive dimensions at the territorial level. The Terrestrial questions the relationship between human and non-human agents and highlights the role of territory in charting the course of politics. The territory as a response to the environmental and social crisis, and as the only future horizon for both old and new inhabitants. The adoption of circular economy policies leads to a confrontation with innovative solutions and pushes towards increased sustainability of cities and their production systems. The city of Prato, known for its textile district, has promoted integrated policies and strategies to accelerate the circular transition. Prato Circular City has as its strengths the involvement of local stakeholders and a methodological approach based on governance that addresses priority issues for the definition of shared policies. The circular city model is a possible response of the territory to the crisis: a strategy to promote innovation, social cohesion and territorial resilience.

description: It is well-known that the Kontsevich formality [K97] for Hochschild cochains of the polynomial algebra $A=S(V^*)$ fails if the vector space $V$ is infinite-dimensional. In the present paper, we study the corresponding obstructions. We construct an $L_\infty$ structure on polyvector fields on $V$ having the even degree Taylor components, with the degree 2 component given by the Schouten-Nijenhuis bracket, but having as well higher non-vanishing Taylor components. We prove that this $L_\infty$ algebra is quasi-isomorphic to the corresponding Hochschild cochain complex. We prove that our $L_\infty$ algebra is $L_\infty$ quasi-isomorphic to the Lie algebra of polyvector fields on $V$ with the Schouten-Nijenhuis bracket, if $V$ is finite-dimensional.

description: The behaviour of the turbulent Prandtl number ($Pr_t$) for buoyancy-affected flows near a vertical surface is investigated as an extension study of {Gibson \& Leslie, \emph{Int. Comm. Heat Mass Transfer}, Vol. 11, pp. 73-84 (1984)}. By analysing the location of mean velocity maxima in a differentially heated vertical planar channel, we {identify an} {infinity anomaly} for the eddy viscosity $ν_t$ and the turbulent Prandtl number $Pr_t$, as both terms are divided by the mean velocity gradient according to the standard definition, in vertical buoyant flow. To predict the quantities of interest, e.g. the Nusselt number, a machine learning framework via symbolic regression is used with various cost functions, e.g. the mean velocity gradient, with the aid of the latest direct numerical simulation (DNS) dataset for vertical natural and mixed convection. The study has yielded two key outcomes: $(i)$ the new machine learnt algebraic models, as the reciprocal of $Pr_t$, successfully handle the infinity issue for both vertical natural and mixed convection; and $(ii)$ the proposed models with embedded coordinate frame invariance can be conveniently implemented in the Reynolds-averaged scalar equation and are proven to be robust and accurate in the current parameter space, where the Rayleigh number spans from $10^5$ to $10^9 $ for vertical natural convection and the bulk Richardson number $Ri_b $ is in the range of $ 0$ and $ 0.1$ for vertical mixed convection.

description: We present new fully self-consistent models of the formation and evolution of isolated dwarf galaxies. We have used the publicly available N-body/SPH code HYDRA, to which we have added a set of star formation criteria, and prescriptions for chemical enrichment (taking into account contributions from both SNIa and SNII), supernova feedback, and gas cooling. The models follow the evolution of an initially homogeneous gas cloud collapsing in a pre-existing dark-matter halo. These simplified initial conditions are supported by the merger trees of isolated dwarf galaxies extracted from the milli-Millennium Simulation. The star-formation histories of the model galaxies exhibit burst-like behaviour. These bursts are a consequence of the blow-out and subsequent in-fall of gas. The amount of gas that leaves the galaxy for good is found to be small, in absolute numbers, ranging between 3x10^7 Msol and 6x10^7 Msol . For the least massive models, however, this is over 80 per cent of their initial gas mass. The local fluctuations in gas density are strong enough to trigger star-bursts in the massive models, or to inhibit anything more than small residual star formation for the less massive models. Between these star-bursts there can be time intervals of several Gyrs. We have compared model predictions with available data for the relations between luminosity and surface brightness profile, half-light radius, central velocity dispersion, broad band colour (B-V) and metallicity, as well as the location relative to the fundamental plane. The properties of the model dwarf galaxies agree quite well with those of observed dwarf galaxies.

description: In this work we investigate the Wigner localization of two interacting electrons at very low density in two and three dimensions using the exact diagonalization of the many-body Hamiltonian. We use our recently developed method based on Clifford periodic boundary conditions with a renormalized distance in the Coulomb potential. To accurately represent the electronic wave function we use a regular distribution in space of gaussian-type orbitals and we take advantage of the translational symmetry of the system to efficiently calculate the electronic wave function. We are thus able to accurately describe the wave function up to very low density. We validate our approach by comparing our results to a semi-classical model that becomes exact in the low-density limit. With our approach we are able to observe the Wigner localization without ambiguity.

description: In the everchanging and mobile territory of the Amazon rainforest, the imposition of a rural-urban divide results in the unsustainability of settlements that appeared as sites of extraction at the turn of the twentieth century. Accelerated changes and transformations in urbanisation patterns and in climatic conditions call for the necessity to explore alternative city-making models that are better able to adapt to and promote multiple ways of being and of interdependence between humans and nature. The lifestyles and worldvisions of Amazonian urbanites already speak of the possibilities of reimagining what Christine Padoch calls ‘urban forests and rural cities.’ Through collective experimentation, we depict how the co-production of collective infrastructures of care could allow strengthening the relational socio-natural practices needed for a reconfiguration of Amazonian urbanism.

Superconductivity from charge order in cuprates

description: Superconductivity in layered cuprates is induced by doping holes into a parent antiferromagnetic insulator. It is now recognized that another common emergent order involves charge stripes, and our understanding of the relationship between charge stripes and superconductivity has been evolving. Here we review studies of 214 cuprate families obtained by doping La$_2$CuO$_4$. Charge-stripe order tends to compete with bulk superconductivity; nevertheless, there is plentiful evidence that it coexists with two-dimensional superconductivity. This has been interpreted in terms of pair-density-wave superconductivity, and the perspective has shifted from competing to intertwined orders. In fact, a new picture of superconductivity based on pairing within charge stripes has been proposed, as we discuss.

description: The use of graphene in a form of discontinuous flakes in polymer composites limits the full exploitation of the unique properties of graphene, thus requiring high filler loadings for achieving - for example - satisfactory electrical and mechanical properties. Herein centimetre-scale CVD graphene/polymer nanolaminates have been produced by using an iterative 'lift-off/float-on' process and have been found to outperform, for the same graphene content, state-of-the-art flake-based graphene polymer composites in terms of mechanical reinforcement and electrical properties. Most importantly these thin laminate materials show a high electromagnetic interference (EMI) shielding effectiveness, reaching 60 dB for a small thickness of 33 micron, and an absolute EMI shielding effectiveness close to 3* 10 ^5 dB cm ^2 g^-1 which is amongst the highest values for synthetic, non-metallic materials produced to date.

description: Overcoming the current emergency phase calls for a profound rethinking of the approach to the project. The 'ecological transition' to which the main European policies are oriented is the mainstay for a different economic growth, to promote actions that can improve the ecosystems and the landscape in which we live. The strong need for planning will have to respond looking at the complexity of the design of the changing contexts, with an approach that is free from rigidity and from the need for a rapid execution, to propose instead, dynamic reflection fields. The contribution starts from the issue of urban forestation, as a field of reflection of the ecological transition project, facing it in spatial terms for social and environmental sustainability. Considering both the symbol and the scientific and ambivalent meaning that the forest has had over time, the contribute examines as, in the urban project, the use of the forest as a ‘pioneer landscape’ can usefully be placed in the national strategies, innovating the practice.

Subjects: Compétences sociales ; capital social ; ressources ; mobilisation ; PME.

description: La place des ressources externes dans la création et le développement des PME est assez cruciale, voire vitale, l’absence de ces moyens pouvant entraîner la disparition des PME. Le défi est donc la mobilisation des ressources nécessaires pour la survie de l’entreprise. À cet effet, les compétences sociales et le capital social de l’entrepreneur sont d’un apport capital. Aussi, le travail s’affaire-t-il à l’analyse de l’effet du capital social dans la relation entre la compétence sociale de l’entrepreneur et la mobilisation des ressources (financières et informationnelles). Les données utilisées sont issues d’une enquête par questionnaire appliqué à des entreprises de quatre cent trente (430) entrepreneurs de la ville d’Abidjan. L’outil statistique utilisé est le logiciel SPSS, Amos Version 23, à travers les équations structurelles. Cette analyse nous a permis de mettre en évidence l’existence d’un lien assez déterminant entre certaines composantes de la compétence sociale de l’entrepreneur et sa capacité à mobiliser des ressources externes, grâce au capital social. Nos résultats montrent le rôle amplificateur joué par le capital social dans la relation entre nos différentes variables.

description: We show that the performance and functionality of atom-chips can be transformed by using graphene-based van der Waals heterostructures to overcome present limitations on the lifetime of the trapped atom cloud and on its proximity to the chip surface. Our analysis involves Green-function calculations of the thermal (Johnson) noise and Casimir-Polder atom-surface attraction produced by the atom-chip. This enables us to determine the lifetime limitations produced by spin-flip, tunneling and three-body collisional losses. Compared with atom-chips that use thick metallic conductors and substrates, atom-chip structures based on two-dimensional materials reduce the minimum attainable atom-surface separation to a few 100 nm and increase the lifetimes of the trapped atom clouds by orders of magnitude so that they are limited only by the quality of the background vacuum. We predict that atom-chips with two-dimensional conductors will also reduce spatial fluctuations in the trapping potential originating from imperfections in the conductor patterns. These advantages will enhance the performance of atom-chips for quantum sensing applications and for fundamental studies of complex quantum systems.

Deformed Special Relativity with an energy barrier of a minimum speed

description: This research aims to introduce a new principle in the flat space-time geometry through the elimination of the classical idea of rest and by including a universal minimum limit of speed in the quantum world. This limit, unattainable by the particles, represents a preferred inertial reference frame associated with a universal background field that breaks Lorentz symmetry. There emerges a new relativistic dynamics where a minimum speed forms an inferior energy barrier. One of the interesting consequences of the existence of such a minimum speed is that it prevents the absolute zero temperature for an ultracold gas according to the third law of thermodynamics. So we will be able to provide a fundamental dynamical explanation for the third law through a connection between such a phenomenological law and the new relativistic dynamics with a minimum speed.

description: The paper gives a short overview of the global situation. The difficulty to compare a city with another one is underlined. From the analysis on the pandemic confinement, we can see that the urban discomfort is different in the different residential areas. The paper also emphasises the role of the urban plan and it looks at the Italian spending plan for #NextGenerationItalia and the potential falling back on the future urban organisation. We recall the main theories and the best practices of the near past. The strategic significance of the relationship between the future economic model and the cities.

Getting prepared to be surprised?

description: On a radio programme at the beginning of May 2021, philosopher and psychoanalyst Romano Madera observed that although there will always be a new crisis that will sneak up on us, we can do something crucial: we can get prepared to be surprised by crises. This apparently contradictory statement, and the context it stems from, triggered a reflection on planning and radical uncertainty, and solicited us to map existing and emerging approaches that planning theory has used to address (un)known unknowns. Starting from this map and contextualising this discussion in recent responses to the COVID-19 crisis, we argue that radical uncertainty requires planning and design to move into two complementary dimensions; namely, navigating by sight through the implementation of plural approaches, and at the same time, tracing/adjusting the route, by the choice of the horizon of meaning that gives direction to our actions.

description: Will we terrestrials be richer or poorer, safer or more insecure, better-off or worse in the future world? It depends on how, in today’s unprecedented crisis, we will correct errors and injustices made during the last 30 years of globalization. Today’s world is guided by irresponsible élites who have placed the Earth at risk, and have produced a planetary new plebs poorer and vulnerable, whereas the creative class is gifted with knowledge but powerless. Tomorrow’s world can be a ‘glocal’ intelligent society. How to reach it is a matter of close dialogue with modernity and progress to fully rethink.

Radio Source Heating in the ICM: The Example of Cygnus A

description: One of the most promising solutions for the cooling flow problem involves energy injection from the central AGN. However it is still not clear how collimated jets can heat the ICM at large scale, and very little is known concerning the effect of radio lobe expansion as they enter into pressure equilibrium with the surrounding cluster gas. Cygnus A is one of the best examples of a nearby powerful radio galaxy for which the synchrotron emitting plasma and thermal emitting intra-cluster medium can be mapped in fine detail, and previous observations have inferred possible shock structure at the location of the cocoon. We use new XMM-Newton observations of Cygnus A, in combination with deep Chandra observations, to measure the temperature of the intra-cluster medium around the expanding radio cavities. We investigate how inflation of the cavities may relate to shock heating of the intra-cluster gas, and whether such a mechanism is sufficient to provide enough energy to offset cooling to the extent observed.

description: Frequently-Asked-Question (FAQ) retrieval provides an effective procedure for responding to user's natural language based queries. Such platforms are becoming common in enterprise chatbots, product question answering, and preliminary technical support for customers. However, the challenge in such scenarios lies in bridging the lexical and semantic gap between varied query formulations and the corresponding answers, both of which typically have a very short span. This paper proposes TI-S2S, a novel learning framework combining TF-IDF based keyword extraction and Word2Vec embeddings for training a Sequence-to-Sequence (Seq2Seq) architecture. It achieves high precision for FAQ retrieval by better understanding the underlying intent of a user question captured via the representative keywords. We further propose a variant with an additional neural network module for guiding retrieval via relevant candidate identification based on similarity features. Experiments on publicly available dataset depict our approaches to provide around 92% precision-at-rank-5, exhibiting nearly 13% improvement over existing approaches.
