description: Classical viscid media are quite common in our everyday life. However, we are not used to find such media in quantum mechanics, and much less to analyze their effects on the dynamics of quantum systems. In this regard, the Caldirola-Kanai time-dependent Hamiltonian constitutes an appealing model, accounting for friction without including environmental fluctuations (as it happens, for example, with quantum Brownian motion). Here, a Bohmian analysis of the associated friction dynamics is provided in order to understand how a hypothetical, purely quantum viscid medium would act on a wave packet from a (quantum) hydrodynamic viewpoint. To this purpose, a series of paradigmatic contexts have been chosen, such as the free particle, the motion under the action of a linear potential, the harmonic oscillator, or the superposition of two coherent wave packets. Apart from their analyticity, these examples illustrate interesting emerging behaviors, such as localization by "quantum freezing" or a particular type of quantum-classical correspondence. The reliability of the results analytically determined has been checked by means of numerical simulations, which has served to investigate other problems lacking of such analyticity (e.g., the coherent superpositions).

description: (0,2) gauged linear sigma models with torsion, corresponding to principal torus bundles over warped CY bases, provide a useful framework for getting exact statements about perturbative dualities in the presence of fluxes. In this context we first study dualities mapping the torus fiber onto itself, implying the existence of quantization constraints on the torus moduli for consistency. Second, we investigate dualities mixing the principal torus bundle with the gauge bundle, relating the torsional GLSMs to ordinary ones corresponding to CY compactifications with non-standard embeddings, namely two classes of models with different target-space topologies.

Publisher: name: Italiano LinguaDue
Year: 2021

description: Dopo una breve riflessione sulle politiche migratorie italiane degli ultimi decenni, il contributo offre una sintetica panoramica della disciplina legislativa italiana delle politiche di immigrazione. Soffermandosi sul permesso di soggiorno con scadenza, sul permesso di soggiorno di lungo periodo e sulla cittadinanza, si indicheranno i requisiti linguistici fissati, le procedure stabilite per la loro verifica e, quando previste, le attività formative obbligatorie. Inoltre, sulla base degli esiti delle sessioni di marzo 2019 e febbraio 2020 del Test di conoscenza della lingua italiana a livello A2 somministrato dai CPIA in accordo con le prefetture e grazie alle osservazioni fatte da un gruppo di docenti di lingua italiana per discenti di lingua straniera, noti anche come A23, in servizio nei CPIA, il contributo si propone di capire se le criticità osservate nel corso degli anni sono state affrontate. Language tests for integration and citizenship: some reflections on the Italian situation This paper is about migration policies and language testing in Italy. After a general overview of the immigration policies in recent decades, we focus on policy requirements for residency and citizenship. We describe the language requirements, the procedures established for their assessment and, if provided, the specific set of official courses. Thanks to the analysis of the results of A2 tests for the long-term residency permits administrated in March 2019 and February 2020 and taking into consideration some remarks made by a group of Italian L2 teachers who work in the CPIAs, the paper aims to understand if the critical issues observed over the years have been addressed properly.

description: The shock-acceleration theory predicts a power-law energy spectrum in the test particle approximation, and there are two ways to calculate a power-law index, Peacock's approximation and Vietri's formulation. In Peacock's approximation, it is assumed that particles cross a shock front many times and energy-gains for each step are fully uncorrelated. On the other hand, correlation of the distribution of an energy-gain factor for a particle is considered in Vietri's formulation. We examine how Peacock's approximation differs from Vietri's formulation. It is useful to know when we can use Peacock's approximation because Peacock's approximation is simple to derive the power-law index. In addition, we focus on how the variance of the energy-gain factor has an influence on the difference between Vietri's formulation and Peacock's approximation. The effect of the variance has not been examined well until now. For demonstration, we consider two cases for the scattering in the upstream: the large-angle scattering (model A) and the regular deflection by large-scale magnetic fields (model B). Especially there is no correlation among the distribution of an energy-gain factor for every step in model A. In this model, we see the power-law index derived from Peacock's approximation differs from the one derived from Vietri's formulation when we consider the mildly-relativistic shock, and the variance of the energy-gain factor affects this difference. We can use Peacock's approximation for a non-relativistic shock and a highly-relativistic shock because the effect of the variance is hidden. In model B, we see the difference of the power-law converging along the shock velocity.

description: Quantum computing in terms of geometric phases, i.e. Berry or Aharonov-Anandan phases, is fault-tolerant to a certain degree. We examine its implementation based on Zeeman coupling with a rotating field and isotropic Heisenberg interaction, which describe NMR and can also be realized in quantum dots and cold atoms. Using a novel physical representation of the qubit basis states, we construct $π/8$ and Hadamard gates based on Berry and Aharonov-Anandan phases. For two interacting qubits in a rotating field, we find that it is always impossible to construct a two-qubit gate based on Berry phases, or based on Aharonov-Anandan phases when the gyromagnetic ratios of the two qubits are equal. In implementing a universal set of quantum gates, one may combine geometric $π/8$ and Hadamard gates and dynamical $\sqrt{\rm SWAP}$ gate.

description: Il presente contributo focalizza l’attenzione sulla dimensione relazionale e interpersonale dell’apprendimento linguistico attraverso una lettura di tipo trasversale dei descrittori di Mediazione del Volume complementare del QCER (2020). Un’attenta analisi dei descrittori “Mediare a livello concettuale” e “Mediare a livello comunicativo” ha permesso di evidenziare come in essi si faccia riferimento a competenze non solo strettamente linguistiche ma anche a competenze più generali, le life skills, come illustrato nel documento dell’Organizzazione Mondiale della Salute Life Skills Education for children and adolescents in Schools (OMS, 1997). «Assumere diversi ruoli in funzione dei bisogni dei partecipanti», come recita uno dei descrittori di mediazione del QCER Volume complementare (2020: 121), implica anche che gli apprendenti siano in grado di usare la lingua in modo efficace in relazione al ruolo da loro assunto in contesti sociali differenti. Usare la lingua efficacemente chiama in causa una competenza più ampia che riguarda la capacità di usare una comunicazione efficace (effective communication), e sapere usare una comunicazione efficace è anche una delle dieci life skills richieste dall’OMS (1997). Dunque, passando dai descrittori del QCER Volume complementare e alle life skills del documento dell’OMS, nel presente contributo si farà riferimento ad alcuni possibili percorsi trasversali che danno il giusto peso alla formazione linguistica nella sua dimensione più ampia del termine. Life skills in the CEFR Companion volume This paper focuses on the relational and interpersonal dimension of language learning through a transversal reading of the CEFR Companion volume (2020). A careful analysis of the “Mediating concepts” and “Mediating communication” underlying the new descriptors highlights how they are not limited to language skills, but also include more general skills, namely life skills. These are set out in the Document by the World Health Organization entitled Life Skills Education for children and adolescents in Schools (WHO, 1997). One of the objectives of mediation in the CEFR Companion volume descriptors (2020: 121) is the ability to assume different roles corresponding to individual needs within a given social context. They require that learners be able to use the language effectively in different social contexts. Using language effectively underlies the need for boosting overall communication ability, one of the ten life skills set out in the WHO document (1997). Starting from the CEFR Companion volume descriptors and Life Skills in the WHO document, this contribution will refer to interconnecting paths that give due weight to language training in the broadest sense.

A BRIEF PRACTICAL-GUIDE FOR L2-TEACHERS: K-2 AMERICAN CHILDREN LEARN ITALIAN
Creators: name: Greco, Matteo
Publisher: name: Italiano LinguaDue
Year: 2021

description: This paper aims to provide some good techniques and strategies L2 teachers may adopt in order to encourage greater involvement in younger children (from kindergarten to second grade). These techniques are theoretical-guided and support the idea that the whole person is involved in the learning activity. Therefore, the teaching experience becomes a multidimensional approach: it can feature creative tasks, like painting and drawing, as well as practical ones, such as cooking and reciting; static activities, such as singing, as well as active ones, like jumping and dancing; memory tasks, such as rote repetition, as well as “out the blue” tasks, such as shouting new words out; make use of traditional support materials, such as paper, as well as modern ones, such as videos; etc. This multidimensional approach leads to excellent results in L2 acquisition and it will be exemplified by a project where Italian L2 was taught in a school in the United States. Una breve guida pratica per insegnanti di L2: come i bambini americani in età prescolare imparano l’italiano Il presente lavoro mira a fornire alcune buone tecniche e strategie che gli insegnanti di L2 possono adottare per ottenere un migliore e più forte coinvolgimento dello studente nei primi livelli di scolarità (dalla scuola materna alla seconda elementare). Tali tecniche sono guidate dalla teoria e sostengono l’idea che l’intera persona sia coinvolta nell’attività di apprendimento. Pertanto, l’esperienza di insegnamento deve affrontare un approccio multidimensionale: si dovrebbero adottare compiti creativi, come dipingere e disegnare, al pari di quelli pratici, come cucinare e recitare; si dovrebbero adottare attività come cantare, così come attività motorie, come saltare e ballare; compiti di memoria, come ripetere a memoria, così come attività di improvvisazione, ad es. gridare nuove parole; infine si dovrebbero adottare, accanto a risorse moderne come i video, materiali di supporto tradizionali, come la carta, ecc. Un tale approccio multidimensionale ottiene ottimi risultati nell'acquisizione della L2 come dimostra il progetto qui esposto in cui l’italiano è stato insegnato come L2 in una scuola degli Stati Uniti.

description: Complex software systems are becoming increasingly prevalent in aerospace applications: in particular, to accomplish critical tasks. Ensuring the safety of these systems is crucial, as they can have subtly different behaviors under slight variations in operating conditions. This paper advocates the use of formal verification techniques and in particular theorem proving for hybrid software-intensive systems as a well-founded complementary approach to the classical aerospace verification and validation techniques, such as testing or simulation. As an illustration of these techniques, a novel lateral midair collision-avoidance maneuver is studied in an ideal setting, without accounting for the uncertainties of the physical reality. The challenges that naturally arise when applying such technology to industrial-scale applications is then detailed, and proposals are given on how to address these issues.

description: We present a multi-wavelength analysis of a $\sim$30$' \times$30$'$ area around the Sh 2-53 region (hereafter S53 complex), which is associated with at least three H II regions, two mid-infrared bubbles (N21 and N22), and infrared dark clouds. The $^{13}$CO line data trace the molecular content of the S53 complex in a velocity range of 36--60 km s$^{-1}$, and show the presence of at least three molecular components within the selected area along this direction. Using the observed radio continuum flux of the H II regions, the derived spectral types of the ionizing sources agree well with the previously reported results. The S53 complex harbors clusters of young stellar objects (YSOs) that are identified using the photometric 2--24 $μ$m magnitudes. It also hosts several massive condensations (3000-30000 $M_\odot$) which are traced in the {\em Herschel} column density map. The complex is found at the junction of at least five molecular filaments, and the flow of gas toward the junction is evident in the velocity space of the $^{13}$CO data. Together, the S53 complex is embedded in a very similar "hub-filament" system to those reported in Myers, and the active star formation is evident towards the central "hub" inferred by the presence of the clustering of YSOs.

I docenti intervistati non provengono dallo stesso contesto lavorativo: alcuni di essi lavorano per istituzioni di tipo privato, altri di tipo pubblico. Inoltre alcuni operano in Cina, altri in Italia; alcuni sono di nazionalità cinese, altri italiana. Proprio la provenienza eterogenea per nazionalità e contesti operativi rende lo studio un interessante specchio della situazione attuale dell’insegnamento dell’italiano a studenti cinesi a livello accademico.

The teachers interviewed do not come from the same working context: some of them work for private institutions, others for public ones. Moreover, some work in China, others in Italy; some are of Chinese nationality, others Italian. It is precisely this heterogeneous origin in terms of nationality and operating contexts that makes the study an interesting mirror of the current situation of teaching Italian to Chinese students at the academic level.

description: The spin Edelstein effect has proven to be a promising phenomenon to generate spin polarization from a charge current in systems without inversion symmetry. In recent years, a current-induced orbital magnetization, called the orbital Edelstein effect, has been predicted for various systems with broken inversion symmetry, using the atom-centered approximation and the modern theory of orbital magnetization. In this paper, we study the current-induced spin and orbital magnetization for a bilayer system with Rashba interaction, using the modern theory of orbital magnetization and Boltzmann transport theory in the relaxation time approximation. We find that the spin Edelstein effect is significantly larger than the orbital contribution. Furthermore, the orbital Edelstein response can be enhanced, suppressed, and even reversed, depending on the relation of the effective Rashba parameters of each layer. A sign change of the orbital polarization is related to an interchange of the corresponding layer localization of the states.

description: We give a uniform algebraic framework for computing hybrid spectral transforms in an efficient manner. Based on properties of the Kronecker product, we derive a set of recursive equations, which leads naturally to an algorithm for computing such transforms efficiently. As a result, many applications of transforms like the Walsh transform and the Reed-Muller transform, which were previously impossible because of memory constraints, have now become feasible. The same set of recursive equations also gives a new way of explaining hybrid transform diagrams, an efficient data-structure for integer valued Boolean functions
Conformal Frame dependence on Cosmological Observations in Scalar-Tensor Theories of Gravity

description: Cosmological observations provide more accurate values both for background evolution of the Universe and for the structure formation. These values are given by the so-called dark energy equation of state, $ω$ and the growth index parameter, $γ$. From these observed parameters, one can reconstruct the model functions in scalar tensor gravity theories. However, there is a long standing debate about the (in)equality between conformally transformed frames in scalar tensor gravity models. We show that cosmological observables are frame dependent when they are described by frame independent parameter, redshift. Thus, if the cosmological observables are interpreted in one frame, then all of the observables should also be interpreted in that frame. This explicitly shows the conformal inequality of cosmological observables. Also, our method provides the model independent analysis for STG models about various observables in both frames.

description: Hydrogels were prepared by Steglich esterification and by crosslinking pre-synthesized poly(sorbitol adipate)-graft-poly(ethylene glycol) mono methyl ether (PSA-g-mPEG) using different-chain-length-based disuccinyl PEG. PSA and PSA-g-mPEG were investigated for polymer degradation as a function of time at different temperatures. PSA-g-mPEG hydrogels were then evaluated for their most crucial properties of swelling that rendered them suitable for many pharmaceutical and biomedical applications. Hydrogels were also examined for their Sol-Gel content in order to investigate the degree of cross-linking. Physical structural parameters of the hydrogels were theoretically estimated using the modified Flory–Rehner theory to obtain approximate values of polymer volume fraction, the molecular weight between two crosslinks, and the mesh size of the hydrogels. X-ray diffraction was conducted to detect the presence or absence of crystalline regions in the hydrogels. PSA-g-mPEG hydrogels were then extensively examined for higher and lower molecular weight solute release through analysis by fluorescence spectroscopy. Finally, the cytotoxicity of the hydrogels was also investigated using a resazurin reduction assay. Experimental results show that PSA-g-mPEG provides an option as a biocompatible polymer to be used for pharmaceutical applications.

description: Objectives: The aim of our current study was to analyze whether the use of important measures of methodological quality and reporting of randomized clinical trials published in the field of cardiovascular disease research haschanged over time. A furtheraim was to investigate whether there was an improvement over time in the ability of these trials to provide a good estimate of the true intervention effect. Methods: We conducted two searches in the Cochrane Central Register of Controlled Trials (CENTAL) database to identify randomized cardiovascular clinical trials published in either 2012 or 2017. Randomized clinical trials (RCTs) trials in cardiovascular disease research with adult participants were eligible to be included. We randomly selected 250 RCTs for publication years 2012 and 2017. Trial characteristics, data on measures of methodological quality, and reporting were extracted and the risk of bias for each trial was assessed. Results: As compared to 2012, in 2017 there were significant improvements in the reporting of the presence of a data monitoring committee (42.0% in 2017 compared to 34.4% in 2012; p < 0.001), and a positive change in registering randomized cardiovascular disease research in clinical trial registries (78.4% in 2017 compared to 68.9% in 2012; p = 0.03). We also observed that significantly more RCTs reported sample size calculation (60.4% in 2017 compared to 49.6% in 2012; p < 0.01) in 2017 as compared to 2012. RCTs in 2017 were more likely to have a low overall risk of bias (RoB) than in 2012 (29.2% in 2017 compared to 21.2% in 2012; p < 0.01). However, fewer 2017 RCTs were rated low (50.8% compared to 65.6%; p < 0.001) risk for blinding of participants and personnel, for blinding of outcome assessors (82.4% compared to 90.8%; p < 0.001), and selective outcome reporting (62.8% compared to 80.0%; <0.001). Conclusions: As compared to 2012, in 2017 there were significant improvements in some, but not all, the important measures of methodological quality. Although more trials in the field of cardiovascular disease research had a lower overall RoB in 2017, the improvement over time was not consistently perceived in all RoB domains.
Generalised cusp anomalous dimension in beta-deformed super Yang Mills theory

Year: 2013
Subjects: subject: High Energy Physics - Theory (hep-th)

description: In this work we study the cusp anomalous dimension of the marginally deformed N=4 sYM theory. We find the expression of the cusp anomalous dimension both at the weak and strong coupling limits. On the gravity side we partially map the system of equations to that of undeformed N=4 sYM, by defining in the internal space an effective angle Δθ_{eff} which depends on the deformation parameter. The cusp anomalous dimension then can be read from that of the N=4 sYM theory, by using this effective angle instead of the usual angle of the undeformed 5-sphere. In the weak coupling regime we find no beta dependence up to two loops. Based on these results we conjecture that for any value of lambda, the cusp anomalous dimension is given by the N=4 sYM result using the coupling dependent effective angle. As a consequence of this, we derive a BPS-like condition between the angle of the AdS space and the Δθ_{eff} of the deformed sphere which when satisfied, nullifies the cusp anomalous dimension.

The physically most important dissipations are studied, Rayleigh and Reynolds dissipation, Landau damping, dissipation in a laminar boundary layer and Chezy friction on a rough bottom. The decay laws for the soliton parameters, that is amplitude, velocity and width, are found in analytical form and are compared with the results of direct numerical modelling.

description: Il contributo riporta i primi dati di un’indagine qualitativa finalizzata ad esplorare le percezioni e i bisogni dei docenti che insegnano discipline cosiddette non linguistiche nelle scuole italiane all’estero. Per l’indagine, ci si è serviti di interviste semi-strutturate somministrate a un campione di 34 docenti della scuola primaria e secondaria in servizio in diversi paesi del mondo. Ai docenti è stato chiesto di descrivere nel dettaglio le sfide e le specificità dell’insegnare in contesti bilingui e biculturali all’estero e i bisogni da loro percepiti. In particolare, dopo una breve introduzione sulle scuole italiane dal punto di vista storico-politico e sul profilo dei docenti all’estero, si presenterà il protocollo di intervista e si illustreranno le problematiche relative all’integrazione del curriculum italiano e di quello locale e all’insegnamento di contenuti disciplinari in classi linguisticamente e culturalmente eterogenee, nonché i bisogni di formazione e di collaborazione espressi dai docenti. Teaching in Italian abroad: teachers’ perceptions and needs This paper presents data recently collected through a qualitative study aimed at exploring the perceptions and needs of content teachers currently employed in Italian international schools abroad. Semi-structured interviews were collected from 34 primary and secondary teachers working around the world. Teachers were asked to describe the characteristics and challenges of teaching in bilingual and bicultural schools abroad and their perceived needs. After briefly introducing the context of the Italian international schools abroad from both a historical and a political perspective and describing the profile of the expat teacher, the paper outlines the interview protocol and discusses the results regarding the challenges of integrating the Italian and local curriculum and teaching content to linguistically and culturally diverse students, as well as the training and collaboration needs perceived by the teachers.

description: A variationally computed $^{28}$SiH$_4$ rotation-vibration line list applicable for temperatures up to $T=1200\,$K is presented. The line list, called OY2T, considers transitions with rotational excitation up to $J=42$ in the wavenumber range $0$--$5000\,$cm$^{-1}$ (wavelengths $λ> 2\,μ$m). Just under 62.7 billion transitions have been calculated between 6.1 million energy levels. Rovibrational calculations have utilized a new `spectroscopic' potential energy surface determined by empirical refinement to 1452 experimentally derived energy levels up to $J=6$, and a previously reported \textit{ab initio} dipole moment surface. The temperature-dependent partition function of silane, the OY2T line list format, and the temperature dependence of the OY2T line list are discussed. Comparisons with the PNNL spectral library and other experimental sources indicate that the OY2T line list is robust and able to accurately reproduce weaker intensity features. The full line list is available from the ExoMol database and the CDS database.

description: Agricultural residues are produced in large quantities and their management is an issue all over the world. Many of these residues consist of plant materials in different degrees of transformation, so returning them back to soil is a management option that closes loops in a circular economy context. The objective of this paper is to summarize current knowledge on the options and effects of reusing agricultural residues as organic soil amendments. The reuse of these residues in soil is a good solution for minimizing the problems associated with their management, while improving soil health and ecosystem functions. While some agricultural residues can be applied directly to soil, others will need previous transformations such as composting to improve their properties. This allows the recovery of plant nutrients and increase in soil organic matter contents, with many positive effects on the soil’s physical, chemical and biological properties, and ultimately, crop production, although potential risks derived from some materials must also be considered. The concept of regenerative agriculture and soil management using organic soil amendments contribute to the significant enhancement of soil biodiversity, the protection of the environment and climate goal achievement.

description: There is a persistent state of confusion regarding the nature of the Unruh effect. We will argue that, in contrast to some interpretations thereof, the effect does not represent any novel physics and that, by its very nature, the effect is fundamentally unmeasurable in all experiments of the kind that have been contemplated until now. Also, we discuss what aspects connected with this effect one might consider as possibilities to be explored empirically and what their precise meaning may be regarding the issue at hand.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

description: The application of patient-derived (PD) in vitro tumor models represents the classical strategy for clinical translational oncology research. Using these cellular heterogeneous cultures for the isolation of cancer stem cells (CSCs), suggested to be the main driver for disease malignancy, relies on the use of surrogate biomarkers or is based on CSC-enriching culture conditions. However, the ability of those strategies to exclusively and efficiently enrich for CSC pool has been questioned. Here we present an alternative in vitro CSC model based on the oncogenic transformation of single clone-derived human induced pluripotent stem cells (hiPSC). Hotspot mutations in the DNA encoding for the R132 codon of the enzyme isocitrate dehydrogenase 1 (IDH1) and codon R175 of p53 are commonly occurring molecular features of different tumors and were selected for our transformation strategy. By choosing p53 mutant glial tumors as our model disease, we show that in vitro therapy discovery tests on IDH1-engineered synthetic CSCs (sCSCs) can identify kinases-targeting chemotherapeutics that preferentially target tumor cells expressing corresponding genetic alteration. In contrast, neural stem cells (NSCs) derived from the IDH1R132H overexpressing hiPSCs increase their resistance to the tested interventions indicating glial–to-neural tissue-dependent differences of IDH1R132H. Taken together, we provide proof for the potential of our sCSC technology as a potent addition to biomarker-driven drug development projects or studies on tumor therapy resistance. Moreover, follow-up projects such as comparing in vitro drug sensitivity profiles of hiPSC-derived tissue progenitors of different lineages, might help to understand a variety of tissue-related functions of IDH1 mutations.

description: Due to the skewed nature of the frequency distribution of term occurrence (e.g., Zipf's law) it is unlikely that any single technique for indexing text can do well in all situations. In this paper we propose a hybrid approach to indexing text, and show how it can outperform the traditional inverted B-tree index both in storage overhead, in time to perform a retrieval, and, for dynamic databases, in time for an insertion, both for single term and for multiple term queries. We demonstrate the benefits of our technique on a database of stories from the Associated Press news wire, and we provide formulae and guidelines on how to make optimal choices of the design parameters in real applications.

description: We study the internal kinematics of galaxy clusters in the region beyond the sphere of virialization. Galaxies around a virialized cluster are infalling towards the cluster centre with a non-zero mean radial velocity. We develop a new formalism for describing the dynamical state of clusters, by generalizing the standard Jeans formalism with the inclusion of the peculiar infall motions of galaxies and the Hubble expansion as well as the contributions due to background cosmology. Using empirical fits to the radial profiles of density, mean radial velocity and velocity anisotropy of both a stacked cluster-mass halo and two isolated halos of a cosmological dark matter only simulation, we verify that our generalized Jeans equation correctly predicts the radial velocity dispersion out to 4 virial radii. We find that the radial velocity dispersion inferred from the standard Jeans equation is accurate up to 2 virial radii, but overestimated by \approx 20% for the stacked halo and by \approx 40% for the isolated halos, in the range \approx 2-3 virial radii. Our model depends on the logarithmic growth rate of the virial radius (function of halo mass or concentration), which we estimate in 7 different ways, and on the departure from self-similarity of the evolution of the peculiar velocity profile in virial units.
