description: Nonlinear ideal magnetohydrodynamic (MHD) simulations of the propagation and expansion of a magnetic "bubble" plasma into a lower density, weakly-magnetized background plasma are presented. These simulations mimic the geometry and parameters of the Plasma Bubble Expansion Experiment (PBEX) [A. G. Lynn, Y. Zhang, S. C. Hsu, H. Li, W. Liu, M. Gilmore, and C. Watts, Bull. Amer. Phys. Soc. {\bf 52}, 53 (2007)], which is studying magnetic bubble expansion as a model for extra-galactic radio lobes. The simulations predict several key features of the bubble evolution. First, the direction of bubble expansion depends on the ratio of the bubble toroidal to poloidal magnetic field, with a higher ratio leading to expansion predominantly in the direction of propagation and a lower ratio leading to expansion predominantly normal to the direction of propagation. Second, an MHD shock and a trailing slow-mode compressible MHD wavefront are formed ahead of the bubble as it propagates into the background plasma. Third, the bubble expansion and propagation develop asymmetries about its propagation axis due to reconnection facilitated by numerical resistivity and to inhomogeneous angular momentum transport mainly due to the background magnetic field. These results will help guide the initial experiments and diagnostic measurements on PBEX.

description: Ultra-high-energy ($>$ 100 TeV) gamma-ray detection benefits from the use of muon detectors (MDs) thanks to their capability of suppressing the cosmic-ray background. More than 1100 8-inch photomultiplier tubes (PMTs), CR365-02-2 from Beijing Hamamatsu Photon Techniques INC. (BHP), will be deployed for the LHAASO-MD experiment. In this paper, the design of the photomultiplier base for CR365-02-2 is presented. Signals are extracted from two outputs: the anode and the 7th dynode. This design ensures a high dynamic range, from single photoelectron (SPE, peak-to-valley ratio $>$ 2), up to bunches of $7\times10^5$ photoelectrons, with an equivalent anode peak current of up to 1600 mA. The anode-to-dynode amplitude ratio (A/D) is below 160 in order to ensure enough overlap between the two outputs. Test results of 4 PMTs, including the SPE response, A/D, linearity, dark count rate, and afterpulse rate, are reported.

description: We consider the cubic-quintic nonlinear Schrödinger equation in two space dimensions. For this model, X. Cheng established scattering for $H^1$ data with mass strictly below that of the ground state for the cubic NLS. Subsequently, R. Carles and C. Sparber utilized the pseudoconformal energy estimate to obtain scattering at the sharp threshold for data belonging to a weighted Sobolev space. In this work, we remove the weighted assumption and establish scattering at the threshold for radial data in $H^1$.

description: In the present paper, we develop a semiclassical quasi-static model accounting for molecular double ionization in an intense laser pulse. With this model, we achieve insight into the dynamics of two highly-correlated valence electrons under the combined influence of a two-center Coulomb potential and an intense laser field, and reveal the significant influence of molecular alignment on the ratio of double over single ion yield. Analysis on the classical trajectories unveils sub-cycle dynamics of the molecular double ionization. Many interesting features, such as the accumulation of emitted electrons in the first and third quadrants of parallel momentum plane, the regular pattern of correlated momentum with respect to the time delay between closest collision and ionization moment, are revealed and successfully explained by back analyzing the classical trajectories. Quantitative agreement with experimental data over a wide range of laser intensities from tunneling to over-the-barrier regime is presented.

THE SALIVA PRECIPITATION INDEX (SPI):
AN INNOVATIVE ANALYTICAL METHOD TO MEASURE WINE ASTRINGENCY
Creators: name: Rinaldi, Alessandra
Publisher: name: Università degli Studi di Napoli Federico II
Year: 2013

description: Quality of food is not easy to define since different working definitions can be formulated depending upon who is defining them and the level at which it is measured. One popular definition comes from a USDA Marketing Workshop Report cited by Gould (1977). It reads “the  combination  of  attributes  or  characteristics  of  a  product  that have  significance  in  determining  the  degree  of  acceptability  of  the  product  to  a  user”. Introducing the definition of the sensory quality, Galvez and Resurrection (1992) term as: “the acceptance of the perceived characteristics of a product by consumers who are the regular users of the product category or those who comprise the target market”. The way we perceive the characteristics of a food as well as beverage is fundamental not only for its conceptual quality but also for its acceptance. Steenkamp’s (1989) concept of perceived quality attempts to mediate between objective product characteristics and consumer preferences. It stresses that perceived quality may differ from objective quality because individual assessments of quality are personal and situational (Holm & Kildevang, 1996). Since perceived quality is an abstract construct and is of a multi-dimensional nature, the development of mesuration tool is a question of vital importance, for both researchers and practitioners.
Astringency is an important sensory characteristic of food and beverages containing polyphenols. This mouthfeel is mainly due to the interactions of polyphenols with salivary proteins, causing complexes formation and their further precipitation, which leads to a reduction of the lubricating properties of saliva. As a consequence, sensations of dryness, hardness, and constriction are felt in the mouth. Wine astringency is generally estimated by tasting, which shows some difficulties in discerning among tastes, is labourious and time-spending and may be restricted to a limited number of samples.
A method that is more objective as possible and that takes into account the multiperceptual phenomenon of astringency is the desired goal for many researchers. In addition, the possibility to evaluate the influence of both grape and wine phenolics, as well as factors and enological practices on astringency is a great challenge also for industry to manage wine quality.

description: A detailed theoretical analysis of the 1s photoionization of neon is presented. It is found that the most significant many-electron correlation in computing photoionization of inner shells is the rearrangement of the outer shells caused by the inner vacancy. Further noticeable effects are: (i) the polarization of the ion core by the outgoing photoelectron and (ii) the coherent effect of double excitation/ionization. The core polarization increases the photoionization cross section by about 10% at the 1s threshold, and the coherent excitation results in further increases by about 5%. Incoherent excitation of the satellite channel leads to an additional 10% increase in the photoabsorption cross section in the double-ionization threshold region.

We discuss the backgrounds from gravitational gradient noise (GGN) in terrestrial detectors, and also binary pulsar and asteroid backgrounds in space-borne detectors. We compare the sensitivities of LIGO and LISA with those of the 100m and 1km stages of the AION terrestrial AI project, as well as two options for the proposed AEDGE AI space mission with cold atom clouds either inside or outside the spacecraft, considering as possible sources the mergers of black holes and neutron stars, supernovae, phase transitions in the early Universe, cosmic strings and quantum fluctuations in the early Universe that could have generated primordial black holes. We also review the capabilities of AION and AEDGE for detecting coherent waves of ultralight scalar dark matter.

A Content Management System for Spatio-Temporal Data: Tadaima
Creators: name: Leano, Vincenza Anna
Publisher: name: Università degli Studi di Napoli Federico II
Year: 2013

description: This thesis focuses on spatio-temporal data modeling and visualization with an application case of study in the Cultural Heritage field.
Spatio-temporal data visualization assumes an important role presenting data to users. Offering a synchronized view on three dimensions of data (i.e. descriptive, temporal and spatial) helps users in their knowledge discovery process.  In Cultural Heritage field, time assumes an important role to explore data. The same timeline could be viewed in different thematic contexts, temporal domain could be stratified and the time reference could be qualitative and imprecise. Managing this kind of features improves the ability of the users to recognize patterns in data.
This thesis presents a framework oriented to the manipulation of Spatio-Temporal data with a particular attention to the temporal specification needs of the Cultural Heritage context, producing a prototype of a Content Management System (CMS). The proposed framework exploits the RDF technology for definition and manipulation of (meta-) data and adopts the OGC standards and open source technologies (PostGIS, Geoserver and Openlayers) for encoding, representing and retrieving spatial information. The available Spatio-Temporal metaphors are parametric, so users can personalize them depending on the specific application context and needs. A real case study in the Cultural Heritage field, concerning spatio-temporal information contained in literary Latin and Greek texts referred to the geographic area of Campi Flegrei (Naples, Italy), describes the framework functionalities.

description: Performance of wave-energy devices of the oscillating water column (OWC) type is greatly enhanced when a resonant condition with the forcing waves is maintained. The natural frequency of such systems can in general be tuned to resonate with a given wave forcing frequency. In this paper we address the tuning of an OWC sea-water pump to polychromatic waves. We report results of wave tank experiments, which were conducted with a scale model of the pump. Also, a numerical solution for the pump equations, which were proven in previous work to successfully describe its behavior when driven by monochromatic waves, is tested with various polychromatic wave spectra. Results of the numerical model forced by the wave trains measured in the wave tank experiments are used to develop a tuning criterion for the sea-water pump.

description: We present a study of heavy quarkonium production in hard diffractive process by the Pomeron exchange for Tevatron and LHC energies. The numerical results are computed using recent experimental determination of the diffractive parton density functions in Pomeron and are corrected by unitarity corrections through gap survival probability factor. We give predictions for single as well as central diffractive ratios. These processes are sensitive to the gluon content of the Pomeron at small Bjorken-x and may be particularly useful in studying the small-x physics. They may also be a good place to test the different available mechanisms for quarkonium production at hadron colliders.

Metes and bounds : a search for archaeological indicators of hunter-gatherer territoriality
Creators: name: Burnard, Linda Louise
Publisher: name: University of British Columbia
Year: 2010

description: The subject of hunter-gatherer territoriality is still a matter of some debate in the anthropological literature. It has been asserted that territorial systems involving perimeter defence and exclusive use rights by fixed membership groups are rare among hunters and gatherers. It has also been suggested that there is an association between this form of land tenure and the evolution of complex society. Since the problem is a developmental one, archaeology, with its developmental and temporal perspective, should be able to contribute to an understanding of this phenomenon. Unfortunately, little attempt has been made to identify material correlates of territorial land use. This thesis seeks to facilitate the development of an archaeologically operational definition of hunter-gatherer territoriality. Toward this end a number of propositions are formulated which postulate relationships between territoriality and various classes of archaeologically observable data. In a comparative/contrastive format the propositions are then applied to data derived from two hunting and gathering societies, the Gitksan and Chilcotin peoples of British Columbia, the one highly territorial, the other with a flexible land use strategy of loosely defined borders and unrestricted access to resources. The study is ethnoarchaeological in that the data base against which the propositions are evaluated, is derived from ethnographic, archival, and archaeological sources. A number of kinds of material patterning related to Gitksan territoriality are identified. Whether the kinds of patterning identified here can be successfully recovered and interpreted in an archaeological context awaits the application of these findings to an archaeological data base. The degree to which the material expression of territorial land use identified in this study are typical of territorial hunters and gatherers in general, also needs to be demonstrated.

description: We perform a detailed calculation of the various contributions to the fluctuation conductivity of a granular metal close to its superconducting transition. We find three distinct regions of power law behavior in reduced temperature, $η=(T-T_c)/T_c$, with crossovers at $Γ/T_c$ and $E_{Th}/T_c$, where $Γ$ is the electron tunneling rate, and $E_{Th}$ is the Thouless energy of a grain. The calculation includes both intergrain and intragrain degrees of freedom. This complete theory of the fluctuation region in granular superconductors is then compared to experimental results from boron-doped nanocrystalline diamond, using the assumption of a constant phase breaking rate, $τ_ϕ^{-1}$. We find a semi-quantitative agreement between the theoretical and experimental results only in the case of large phase breaking. We argue that there may be a novel phase breaking mechanism in granular metals worthy of further experimental and theoretical investigation.

description: This issue concerns the reality of new technologies and services of the information society, which provide society with many professional and social advantages, but which also bring with them a wave of various risks. Nevertheless, as an information society we are happy to use these solutions to an unimaginable extent. It is therefore necessary to ask whether, as a society aspiring to become a 5.0 society, we are sufficiently, or not at all, educated about these technologies, both in terms of their benefits and potential dangers, e.g. cyber threats or impacts on us and our environment? The article presents an analysis of the current forms of education in Poland in 2021 in primary and secondary schools and questions whether, with the development of a reality filled with new technologies and in an era of information overload, we are placing sufficient emphasis on education in the dimension indicated?

Subjects: Carmen Martín Gaite; memoria; emigrazione; letteratura femminile;

description: Beyond historical and social implications, migration represents the possibility of crossing a threshold and opening oneself up to new empirical and emotional spaces. Amparo, the main character of Carmen Martín Gaite’s Irse de casa (1998), is the perfect personification of the gaitian feminine canon. After leaving Spain and settling in New York, she became a successful fashion designer, and seemed happy and easy-going. The bond with memory and the past is the main topic of this novel, as it is in most of Martín Gaite’s production. The window on the past that Amparo closed moving to the US suddenly reappears when she needs to discover herself and her origins. This inconvenience in an anonymous life brings huge changes that will condition her and her loved ones. Travelling to Spain and interacting with places and people connected with her childhood, Amparo goes through the window she had closed forty years before, restoring the order. The window connects the present and the past, symbolizes the emigrant’s transience, personified in the novel by Amparo, who can definitely find the lost serenity and heart’s-ease.

description: The first appearance of radio type II burst emission at decameter-hectometer (DH) waves typically occurs in connection, and often simultaneously, with other types of radio emissions. As type II bursts are signatures of propagating shock waves that are associated with flares and coronal mass ejections (CMEs), a rich variety of radio emissions can be expected. However, sometimes DH type II bursts appear in the dynamic spectra without other or earlier radio signatures. One explanation for them could be that the flare-CME launch happens on the far side of the Sun, and the emission is observed only when the source gets high enough in the solar atmosphere. In this study we have analysed 26 radio type II bursts that started at DH waves and were well-separated ('isolated') from other radio emission features. These bursts were identified from all DH type II bursts observed in 1998-2016, and for 12 events we had observations from at least two different viewing angles with the instruments onboard Wind and STEREO satellites. We found that only 30% of the type II bursts had their source origin on the far side of the Sun, but also that no bursts originated from the central region of the Sun (longitudes E30 - W40). Almost all of the isolated DH type II bursts could be associated with a shock near the CME leading front, and only few were determined to be shocks near the CME flank regions. In this respect our result differs from earlier findings. Our analysis, which included inspection of various CME and radio emission characteristics, suggests that the isolated DH type II bursts could be a special subgroup within DH type II bursts, where the radio emission requires particular coronal conditions to form and to die out.

description: This German-language popular science book entitled 'End of the China illusion. How we must deal with Beijing's power ambitions' comes at a pivotal time (please note that all following translations from German to English are my own). Written by Janka Oertel, Director of the Asia programme and a senior policy fellow at the European Council on Foreign Relations, this book is certain to contribute to an increasingly lively public debate in Germany about how to best engage with autocracies. In the academic discourse John Lough's Germany's Russia Problem or Hamilton and Ohlberg's Hidden Hand: Exposing How the Chinese Communist Party is Reshaping the World have previously shed light on the various challenges emanating from Putin's Russia and Xi's China. In her book, Oertel aims to dispel common misconceptions about China, which she calls the 'China illusion'. Besides the Chinese Communist Party, Oertel believes western entrepreneurs, politicians, and experts also contributed to what she calls the 'myth of modern China'.

Three-dimensional Reconstruction of Coronal Plasma Properties from a Single Perspective
Creators: name: Plowman, Joseph
Publisher: name: arXiv
Year: 2021
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)
subject: FOS: Physical sciences

description: Much of our understanding of the state of coronal plasmas comes from observations that are optically thin. This means that light travels freely through the corona without being materially affected by it, which allows it to be easily seen through, but also results in a line-of-sight degeneracy which has previously thwarted attempts to recover the three-dimensional structure of the coronal plasma. However, although the corona is disorganized in the line-of-sight direction, it is highly organized in the field-aligned direction. This paper demonstrates how to exploit this organization to resolve the line-of-sight degeneracy in the plasma properties using a suitable magnetic field structure. A preliminary investigation with a potential field is shown, finding a solution which clearly resembles the real solar data, even with a single perspective. The results indicate that there is ample information in the resulting residuals that can be used to refine the magnetic field structure, allowing, for the first time, the optically thin plasma observations to speak directly to the magnetic field extrapolations.

description: The integration of two-dimensional transition metal dichalcogenide crystals (TMDCs) into a dielectric environment is critical for optoelectronic and photonic device applications. Here, we investigate the effects of direct deposition of different dielectric materials (Al$_2$O$_3$, SiO$_2$, SiN$_x$) onto atomically thin (monolayer) TMDC WS$_2$ on its optical response. Atomic layer deposition (ALD), electron beam evaporation (EBE), plasma enhanced chemical vapour deposition (PECVD), and magnetron sputtering methods of material deposition are investigated. The photoluminescence (PL) measurements reveal quenching of the excitonic emission after all deposition processes. The reduction in neutral exciton PL is linked to the increased level of charge doping and associated rise of the trion emission, and/or the localized (bound) exciton emission. Furthermore, Raman spectroscopy allows us to clearly correlate the observed changes of excitonic emission with the increased levels of lattice disorder and defects. Overall, the EBE process results in the lowest level of doping and defect densities and preserves the spectral weight of the exciton emission in the PL, as well as the exciton oscillator strength. Encapsulation with ALD appears to cause chemical changes, which makes it distinct from all other techniques. Sputtering is revealed as the most aggressive deposition method for WS$_2$, fully quenching its optical response. Our results demonstrate and quantify the effects of direct deposition of dielectric materials onto monolayer WS$_2$, which can provide a valuable guidance for the efforts to integrate monolayer TMDCs into functional optoelectronic devices.

description: In this work, we develop a polymorphic record calculus with extensible records. Extensible records are records that can have new fields added to them, or preexisting fields removed from them. We also develop a static type system for this calculus and a sound and complete type inference algorithm. Most ML-style polymorphic record calculi that support extensible records are based on row variables. We present an alternative construction based on the polymorphic record calculus developed by Ohori. Ohori based his polymorphic record calculus on the idea of kind restrictions. This allowed him to express polymorphic operations on records such as field selection and modification. With the addition of extensible types, we were able to extend Ohori's original calculus with other powerful operations on records such as field addition and removal.

description: We show that the signature of two boosted $W$-jets plus large missing energy is very promising to probe heavy charged resonances ($X^\pm$) through the process of $pp\to X^+X^-\to W^+W^- X^0 X^0$ where $X^0$ denotes dark matter candidate. The hadronic decay mode of the $W$ boson is considered to maximize the number of signal events. When the mass split between $X^\pm$ and $X^0$ is large, one has to utilize the jet-substructure technique to analyze the boosted $W$-jet. For illustration we consider the process of chargino pair production at the LHC, i.e., $pp\to χ_1^+χ^-_1 \to W^+W^-χ_1^0χ_1^0$, and demonstrate that the proposed signature is able to cover more parameter space of $m_{χ_1^\pm}$ and $m_{χ_1^0}$ than the conventional signature of multiple leptons plus missing energy. More importantly, the signature of our interests is not sensitive to the spin of heavy resonances.

description: The high- and low-frequency descriptions of the pre-decoupling plasma are deduced from the Vlasov-Landau treatment generalized to curved space-times and in the presence of the relativistic fluctuations of the geometry. It is demonstrated that the interplay between one-fluid and two-fluid treatments is mandatory for a complete and reliable calculation of the polarization observables. The Einstein-Boltzmann hierarchy is generalized to handle the dispersive propagation of the electromagnetic disturbances in the pre-decoupling plasma. Given the improved physical and numerical framework, the polarization observables are computed within the magnetized $Λ$CDM paradigm (m$Λ$CDM). In particular, the Faraday-induced B-mode is consistently estimated by taking into account the effects of the magnetic fields on the initial conditions of the Boltzmann hierarchy, on the dynamical equations and on the dispersion relations. The complete calculations of the angular power spectra constitutes the first step for the derivation of magnetized maps of the CMB temperature and polarization which are here obtained for the first time and within the minimal m$Λ$CDM model. The obtained results set the ground for direct experimental scrutiny of large-scale magnetism via the low and high frequency instruments of the Planck explorer satellite.

Quasiparticle energy relaxation in a gas of one-dimensional fermions with Coulomb interaction

description: We consider a system of charged one-dimensional spin-$\frac{1}{2}$ fermions at low temperature. We study how the energy of a highly-excited quasiparticle (or hole) relaxes toward the chemical potential in the regime of weak interactions. The dominant relaxation processes involve collisions with two other fermions. We find a dramatic enhancement of the relaxation rate at low energies, with the rate scaling as the inverse sixth power of the excitation energy. This behavior is caused by the long-range nature of the Coulomb interaction.

description: The quantumness of Dirac paticles for quantized fields in a dilatonic black hole is estimated by means of quantum channel. We develop a general Bloch vector representation of quantum channel in black hole spacetimes beyond single mode approximation. The nonclassicality of Dirac particles can be measured by the minimization of quantum coherence over all orthonormal basis sets. The quantumness of the channel decreases as the dilaton parameter increases. The interplay between the external reservoir noise and dilaton black hole on the dynamical behavior of quantum coherence and steerability is investigated in the Pauli basis. The external environment is modelled by a random telegraph noise channel. The monotonous decay of quantum nonlocality occurs in the weak coupling case. The degradation and revival of quantum nonlocality are observed in the strong coupling condition. It is found that quantum fluctuation effects of the external reservoir can protect quantum coherence and steerability from the information loss of the black hole.

Local Sentences and Mahlo Cardinals

description: Local sentences were introduced by J.-P. Ressayre who proved certain remarkable stretching theorems establishing the equivalence between the existence of finite models for these sentences and the existence of some infinite well ordered models. Two of these stretching theorems were only proved under certain large cardinal axioms but the question of their exact (consistency) strength was left open in [O. Finkel and J.-P. Ressayre, Stretchings, Journal of Symbolic Logic, Volume 61 (2), 1996, p. 563-585 ]. Here, we solve this problem, using a combinatorial result of J. H. Schmerl. In fact, we show that the stretching principles are equivalent to the existence of n-Mahlo cardinals for appropriate integers n. This is done by proving first that for each integer n, there is a local sentence phi_n which has well ordered models of order type alpha, for every infinite ordinal alpha > omega which is not an n-Mahlo cardinal.

description: With the adoption of instructional laboratories (labs) that require students to make their own decisions, there is a need to better understand students' activities as they make sense of their data and decide how to proceed. In particular, understanding when students do not engage productively with unexpected data may provide insights into how to better support students in more open-ended labs. We examine video and audio data from groups within a lab session where students were expected to find data inconsistent with the predictions of two models. In prior work, we examined the actions of the four groups that productively grapple with this designed problem. Here, we analyze the engagement of the three groups that do not. We conducted three phases of analysis: 1) documenting large scale behaviors and time spent in on-topic discussion, 2) analyzing interactions with the teaching assistant, and 3) identifying students' framing--their expectations for what is taking place--when they were discussing their data. Our Phase 1 and 2 analysis show only minor differences between the groups that engaged with the problem and those that did not. Our Phase 3 analysis demonstrated that the groups that did not engage with the problem framed the lab activity as about confirming a known result or as a series of hoops to jump through to fulfill assignment requirements. Implications for instruction include supporting teaching assistants to attend to students' framing and agency within laboratory classrooms.

description: We present self-consistent models of gas in optically-thick dusty disks and calculate its thermal, density and chemical structure. The models focus on an accurate treatment of the upper layers where line emission originates, and at radii $\gtrsim 0.7$ AU. We present results of disks around $\sim 1{\rm M}_{\odot}$ stars where we have varied dust properties, X-ray luminosities and UV luminosities. We separately treat gas and dust thermal balance, and calculate line luminosities at infrared and sub-millimeter wavelengths from all transitions originating in the predominantly neutral gas that lies below the ionized surface of the disk. We find that the [ArII] 7$μ$m, [NeII] 12.8$μ$m, [FeI] 24$μ$m, [SI] 25$μ$m, [FeII] 26$μ$m, [SiII] 35 $μ$m, [OI] 63$μ$m and pure rotational lines of H$_2$, H$_2$O and CO can be quite strong and are good indicators of the presence and distribution of gas in disks. We apply our models to the disk around the nearby young star, TW Hya, and find good agreement between our model calculations and observations. We also predict strong emission lines from the TW Hya disk that are likely to be detected by future facilities. A comparison of CO observations with our models suggests that the gas disk around TW Hya may be truncated to $\sim 120 $ AU, compared to its dust disk of 174 AU. We speculate that photoevaporation due to the strong stellar FUV field from TW Hya is responsible for the gas disk truncation.
