description: Η εργασία ασχολείται με ορισμένες από τις προσαρμοστικές μεθόδους δειγματοληψίας που μπορούν να εφαρμοστούν σε σπάνιους και κρυμμένους πληθυσμούς, με ιδιαίτερη έμφαση στα σχέδια εντοπισμού συνδέσμων. Περιγράφονται οι τρεις πιο δημοφιλείς μέθοδοι σχεδίων εντοπισμού συνδέσμων: η δειγματοληψία χιονοστιβάδας (snowball sampling), ο τυχαίος περίπατος και η RDS (δειγματοληψία καθοδηγούμενη από τους αποκρινόμενους). Γίνεται αναφορά στις διαφορές που παρουσιάζει η RDS από τις άλλες μεθόδους, στα ιδιαίτερα χαρακτηριστικά της και στον τρόπο με τον οποίο συλλέγεται το δείγμα, ενώ παρουσιάζονται οι τρεις πιο ευρέως χρησιμοποιούμενοι εκτιμητές: ο αφελής εκτιμητής, ο εκτιμητής Salganik-Heckathorn και ο εκτιμητής Volz-Heckathorn. Όλοι οι εκτιμητές αξιώνουν η διαδικασία της δειγματοληψίας να είναι με επανάθεση ενώ στην πράξη πρόκειται για δειγματοληψία χωρίς επανάθεση. Με χρήση προσομοίωσης δημιουργείται ένας εικονικός πληθυσμός, διερευνάται η αποτελεσματικότητα των τριών εκτιμητών σε διαδικασία RDS χωρίς επανάθεση και παρουσιάζονται τα αποτελέσματα που προέκυψαν.
description: This Master Thesis deals with specific methods of adaptive sampling designs which can be applied on rare and hidden populations, emphasizing on link tracing designs. In particular, the three most popular (link tracing design) methods are presented: snowball sampling, random walk and respondent driven sampling (RDS). The later is described in depth, compared to the rest of the methods and its special attributes are depicted. An illustration of the sampling procedure is thoroughly given and the three most popular estimators are presented: naïve, Salganik-Heckathorn and Volz-Heckathorn. All these estimators require a sampling procedure with replacement whereas in practice no replacement takes place. Using a simulation, a virtual population is created, the effectiveness of the three estimators is explored using the RDS method without replacement and the generated results are shown.

description: A long-standing problem for models of galaxy formation has been the mismatch between the predicted shape of the mass function of dark matter halos and the observed shape of the luminosity function of galaxies. The number of massive halos is predicted to decrease as a power law (N proportional to M^-2) out to very large masses, while the galaxy luminosity function cuts off exponentially at luminosities above L*. This implies that the efficiency with which gas cools onto massive systems is lower than expected. This letter investigates the role of radio-loud active galactic nuclei (AGN) in continually re-heating the cooling gas. By combining two observational results, the time-averaged energy output associated with recurrent radio source activity is determined, as a function of the black hole mass of the host galaxy: H = 10^21.4 (M_BH / M_sun)^1.6 W. It is shown that for massive elliptical galaxies this radio-source heating balances the radiative energy losses from the hot gas surrounding the galaxy. The recurrent radio-loud AGN activity may therefore provide a self-regulating feedback mechanism capable of controlling the rate of growth of galaxies.

Deep SVBRDF Estimation on Real Materials

description: Recent work has demonstrated that deep learning approaches can successfully be used to recover accurate estimates of the spatially-varying BRDF (SVBRDF) of a surface from as little as a single image. Closer inspection reveals, however, that most approaches in the literature are trained purely on synthetic data, which, while diverse and realistic, is often not representative of the richness of the real world. In this paper, we show that training such networks exclusively on synthetic data is insufficient to achieve adequate results when tested on real data. Our analysis leverages a new dataset of real materials obtained with a novel portable multi-light capture apparatus. Through an extensive series of experiments and with the use of a novel deep learning architecture, we explore two strategies for improving results on real data: finetuning, and a per-material optimization procedure. We show that adapting network weights to real data is of critical importance, resulting in an approach which significantly outperforms previous methods for SVBRDF estimation on real materials.

description: Il contributo presenta i risultati di un primo sondaggio linguistico degli atti completi di un processo per stregoneria istruito dal tribunale del Santo Uffizio di Capua intorno al 1685 ai danni di Agata Basile, una donna originaria di Palermo. Questi atti, per le loro peculiarità procedurali, offrono una documentazione particolarmente interessante e fedele delle competenze linguistiche, molto differenziate, delle persone coinvolte nel processo, dai denuncianti/testimoni all’imputata. Nei limiti di una trascrizione del parlato eseguita con metodi non scientifici, questi documenti offrono una testimonianza di notevole interesse dei tipi di lingua effettivamente in uso, in quel tribunale ecclesiastico, nella comunicazione tra cittadini comuni e autorità costituita. Si formula in conclusione l’ipotesi che la prassi del tribunale prevedesse una fedeltà particolare della trascrizione nei brani di discorso diretto, e che per questo la gamma di realizzazioni che, in essi, che va dal dialetto a una varietà locale più o meno italianizzante, sia il frutto delle scelte linguistiche dei testimoni e non del diverso filtro posto dai verbalizzatori.

description: We use the self-interaction corrected local spin-density approximation to investigate the ground state valency configuration of transition metal (TM = Mn, Co) impurities in n- and p-type ZnO. We find that in pure Zn1-xTMxO, the localized TM2+ configuration is energetically favored over the itinerant d-electron configuration of the local spin density (LSD) picture. Our calculations indicate furthermore that the (+/0) donor level is situated in the ZnO gap. Consequently, for n-type conditions, with the Fermi energy eF close to the conduction band minimum, TM remains in the 2+ charge state, while for p-type conditions, with eF close to the valence band maximum, the 3+ charge state is energetically preferred. In the latter scenario, modeled here by co-doping with N, the additional delocalized d-electron charge transfers into the entire states at the top of the valence band, and hole carriers will only exist, if the N concentration exceeds the TM impurity concentration.

description: In system dynamics, the concept of loop impact measures the effect of a feedback loop on the curvature in the behaviour of the stocks in the loop (Hayward & Boswell, 2014). It is a ratio measure of the acceleration imparted by the loop into a stock and can also be thought of as a ratio measure of the force exerted between adjacent stocks in the loop (Hayward & Roach, 2017). As such, a loop of n stocks is described by n impacts. Loop impact is used to examine regions of loop dominance in stock behaviour. Sometimes, it is helpful to present a dominance analysis for a complete system rather than an individual stock. This paper introduces the concept of average loop impact to explore such a system-wide loop dominance analysis.

La bibliografia ha sottolineato come ciascuna edizione del ricettario costituisca di fatto un prodotto testuale autonomo: il saggio si propone di verificare la fondatezza dell’affermazione anche in riferimento alla sola sezione dialettale. Il rinvenimento della sesta edizione del trattato (1849), sinora considerata irreperibile, ha permesso di instaurare un confronto macro- e microtestuale fra tutte le edizioni della Cucina casereccia, grazie al quale è stato possibile mettere in evidenza le peculiarità di ciascuna di esse e ragionare sulla direzione evolutiva. Lo studio si sofferma anche sulla scelta di Cavalcanti scrivere una sezione del ricettario interamente in dialetto, riepilogando le proposte interpretative sinora avanzate e evidenziando nuovi aspetti a partire dal testo stesso.

description: Owing to the complexity of higher eukaryotic cells, a complete proteome is likely to be very difficult to achieve. However, advantage can be taken of the cell compartmentalization to build organelle proteomes, which can moreover be viewed as specialized tools to study specifically the biology and "physiology" of the target organelle. Within this frame, we report here the construction of the human mitochondrial proteome, using placenta as the source tissue. Protein identification was carried out mainly by peptide mass fingerprinting. The optimization steps in two-dimensional electrophoresis needed for proteome research are discussed. However, the relative paucity of data concerning mitochondrial proteins is still the major limiting factor in building the corresponding proteome, which should be a useful tool for researchers working on human mitochondria and their deficiencies.

description: [Abridged] Recent JWST observations have revealed an intricate filamentary network of unshocked ejecta in the young supernova remnant (SNR) Cassiopeia A (Cas A), offering new insights into supernova (SN) explosions and ejecta evolution. We investigate the origin and evolution of this structure by (i) characterizing its 3D morphology and kinematics and (ii) identifying the physical mechanisms driving its formation. Using high-resolution hydrodynamic (HD) and magneto-hydrodynamic (MHD) simulations, we model the evolution of a neutrino-driven SN from explosion to a remnant age of 1000 years. The initial conditions, set just after shock breakout, are based on a 3D neutrino-driven SN model matching Cas A's basic properties. We find that magnetic fields have little impact on unshocked ejecta evolution, so we focus on HD simulations. A web-like filamentary structure, consistent with JWST observations (down to $\sim 0.01$ pc), naturally forms during the explosion. These filaments arise from early post-collapse processes, including neutrino-heated bubble expansion, hydrodynamic instabilities during blast propagation, and the Ni-bubble effect after shock breakout. The reverse shock later disrupts the filaments via hydrodynamic instabilities, rendering them unobservable by $\sim 700$ years. Our models suggest that JWST-detected filaments in Cas A preserve a 'memory' of early explosion conditions, tracing processes active during and immediately after the SN event. Notably, a filamentary network akin to Cas A's emerges naturally from a neutrino-driven SN explosion.

description: I propose to sharpen the index h, proposed by Hirsch as a useful index to characterize the scientific output of a researcher, by excluding the self-citations. Performing a self-experiment and also analyzing two anonymous data sets, it is shown that self-citations can significantly reduce the $h$ index in contrast to Hirsch's expectations. This result is confirmed by an analysis of 13 further data sets.

Discovering the change prosess : an event based analysis

description: This research has sought to'qualitatively discover the process of change during a successful couples treatment, in an alcohol recovery context, using Experiential System Therapy (Friesen et al., 1989), and the contrasting process in an unsuccessful case of the same therapy, with the same therapist: This is in response to the need for discovery-based process research, to fill the gaps left by outcome research, in examining the complexity of change in a therapeutic setting. Two videotaped episodes in which the male client negotiated his way through an intrapersonal encounter with a previously avoided part of self (an Intrapersonal Resolution event) were examined; one successful, one unsucessful. Elliott's (1993) Comprehensive Process Analysis was employed to provide an extensive exploration of the process, effects and context of both events. The results indicated a number of characteristics common to the co-creation of an Intrapersonal Resolution event (IR), as well as thirteen. discoveries, in which the successful IR event differed from the unsuccessful IR event: (a) process flow, (b) disequilibrium, (c) readiness, (d) symbolic experience, (e) intelligence, (f) forgiveness experience, (g) core conflict, (h) stress level, (i) self support, (j) spiritual support, (k) supportive partner, (1) support network, and(m) individuated interpersonal experience. Primary among these is the concept of client readiness, which can be integrated into a transtheoretical model, based on the work of Prochaska et al. (1992). This has, I believe, significant implications for theorists, therapists, and training centers.
'Strambe' e 'bisbetece': un’analisi stilistica dei 'Vierze' di Filippo Cammarano (1837)

description: Erede di uno dei più celebri Pulcinella del XVIII secolo, Giancola, Filippo Cammarano fu sin dall’infanzia un protagonista del mondo teatrale napoletano a cavallo tra due secoli, se è vero che licenziò la sua prima commedia all’età di appena dieci anni. Oltre all’importante funzione di innovatore del teatro, però, Cammarano fu anche autore di non poche poesie, come testimonia anche la pubblicazione, nel 1837, dei Vierze strambe, e bisbetece. Raccolta giocosa di un vecchio uomo di scena che ripercorre le maggiori tappe della sua carriera, i Vierze si compongono di una vasta gamma di forme metriche, come sonetti, seste rime, ottave, martelliani, fino ad arrivare a curiosi esperimenti come gli strammuottole, le quartine di decasillabi o i cosiddetti vierze a zompariello. Il contributo intende fornire un’analisi di questa tarda opera di Cammarano, coniugando note linguistiche relative al suo napoletano con l’indagine sulle strutture metriche strambe che quello stesso dialetto vivificano e regolano in maniera nuova.

description: Sensitive, high resolution images of the double-double radio galaxy PKS B1545-321 reveal detailed structure, which we interpret in the light of previous work on the interaction of restarted jets with pre-existing relict cocoons. We have also examined the spectral and polarization properties of the source, the color distribution in the optical host and the environment of this galaxy in order to understand its physical evolution. We propose that the restarted jets generate narrow bow shocks and that the inner lobes are a mixture of cocoon plasma reaccelerated at the bow shock and new jet material reaccelerated at the termination shock. The dynamics of the restarted jets implies that their hot spots advance at mildly relativistic speeds with external Mach numbers of at least 5. The existence of supersonic hot spot Mach numbers and bright inner lobes is the result of entrainment causing a reduction in the sound speed of the pre-existing cocoon. The interruption to jet activity in PKS B1545-321 has been brief - lasting less than a few percent of the lifetime $\sim (0.3-2)\times 10^{8} yr$ of the giant radio source. The host galaxy is located at the boundary of a large scale filamentary structure, and shows blue patches in color distribution indicative of a recent merger, which may have triggered the Mpc-scale radio galaxy.

description: We present the results of a coronagraphic scattered-light imaging survey of six young disk candidate stars using the Hubble Space Telescope Advanced Camera for Surveys. The observations made use of the 1.8" occulting spot through the F606W (broad V) filter. Circumstellar material was imaged around HD 97048, a Herbig Ae/Be star located in the Chamaeleon I dark cloud at a distance of 180 pc. The material is seen between ~2" (360 AU) and ~4" (720 AU) from the star in all directions. A V-band azimuthally-averaged radial surface brightness profile peaks at r = 2" with a value of 19.6 +/- 0.2 mag arcsec^-2 and smoothly decreases with projected distance from the star as r^(-3.3 +/- 0.5). An integrated flux of 16.8 +/- 0.1 mag is measured between 2" and 4", corresponding to a scattered-light fractional luminosity lower limit of 8.4 x 10^-4. Filamentary structure resembling spiral arms similar to that seen in Herbig Ae/Be disks is observed. Such structure has been attributed to the influence of orbiting planets or stellar encounters. Average surface brightness upper limits are determined for the five non-detections: HD 34282, HD 139450, HD 158643, HD 159492, and HD 195627. Possible reasons for the non-detections are disks that are too faint or disks hidden by the occulter.

description: Understanding relaxation of supercooled fluids is a major challenge and confining such systems can lead to bewildering behaviour. Here we exploit an optically confined colloidal model system in which we use reduced pressure as a control parameter. The dynamics of the system are ``Arrhenius'' at low and moderate pressure, but at higher pressures relaxation is faster than expected. We associate this faster relaxation with a decrease in density adjacent to the confining boundary due to local ordering in the system enabled by the flexible wall.

description: The authors investigate the magnetic field dependence of the energy splitting between low-lying valley states for electrons in a Si/SiGe quantum well tilted with respect to the crystallographic axis. The presence of atomic steps at the quantum well interface may explain the unexpected, strong suppression of the valley splitting observed in recent experiments. The authors find that the suppression is caused by an interference effect associated with multiple steps, and that the magnetic field dependence arises from the lateral confinement of the electronic wave function. Using numerical simulations, the authors clarify the role of step disorder, obtaining quantitative agreement with the experiments.

description: Los Juegos Olímpicos son más que una competencia deportiva; representan una oportunidad excepcional para las ciudades anfitrionas de convertirse en destinos turísticos de primer nivel y París 2024 nos regaló muchos recuerdos. Desde el 26 de julio hasta el 11 de agosto, la ciudad no solo albergó a atletas de todo el mundo, sino que también atrajo a cientos de miles de turistas. París ha transformado sus calles en escenarios deportivos que resaltan su riqueza cultural y arquitectónica, atrayendo a más de 650,000 turistas durante los días de competición.

Este evento ha generado un repunte del 20% en la ocupación hotelera y un incremento del 8% en el tráfico aéreo, impulsando sectores clave como la alimentación, el ocio y la cultura. París 2024 nos mostró cómo los Juegos Olímpicos pueden actuar como un catalizador para el desarrollo turístico y económico. Sin embargo, la afluencia masiva de visitantes puede presentar desafíos, como el "fenómeno de enjambre", que puede afectar negativamente los recursos turísticos y la vida cotidiana de los residentes. El verdadero reto radica en equilibrar los beneficios con los posibles impactos negativos, garantizando que la ciudad continúe brillando en el escenario global mucho después de que concluyan.

description: In many ranking problems, some particular aspects of the addressed situation should be taken into account in the aggregation process. An example is the presence of correlations between criteria, which may introduce bias in the derived ranking. In these cases, aggregation functions based on a capacity may be used to overcome this inconvenience, such as the Choquet integral or the multilinear model. The adoption of such strategies requires a stage to estimate the parameters of these aggregation operators. This task may be difficult in situations in which we do not have either further information about these parameters or preferences given by the decision maker. Therefore, the aim of this paper is to deal with such situations through an unsupervised approach for capacity identification based on the multilinear model. Our goal is to estimate a capacity that can mitigate the bias introduced by correlations in the decision data and, therefore, to provide a fairer result. The viability of our proposal is attested by numerical experiments with synthetic data

The meaning of stealing as lived in women with bulimia nervosa
Creators: name: McLagan, Beverley May
Publisher: name: University of British Columbia
Year: 2009

description: An exploratory case study using multiple cases investigated the question "What is the meaning of stealing in eating disordered women?" Seven women diagnosed with bulimia nervosa participated in in-depth interviews about this experience. The findings of these interviews revealed commonalities and variations in the patterns and dynamics of both stealing and bulimia. Important information emerged about this experience regarding restrictive family patterns, participants' reactions to these restrictions through stealing and the parallel restrictions and reactions of the bulimic behaviours they later imposed upon themselves. These results add new and in-depth information to the few existing quantitative studies and clinical knowledge addressing stealing in bulimic women. Recommendations for future research and implications for clinical practice were presented.
Two sides of the megalopolis: Educating for sustainable citizenship

description: Despite widespread focus on literacy and math at the expense of other subjects, citizenship and environmental education have an important role in American public education. Citizenship and environmental education are broadly tasked with helping students develop the knowledge, skills, and attitudes needed to shepherd the body politic and natural world, respectively, into the future. For educators and administrators concerned with instructional efficiency, educational farm visits offer one means of pairing these two approaches into a unified learning experience. This paper presents findings from a qualitative case study analysis of two such programs, incorporating interviews with and observations of visiting students, teachers, and parents. The authors argue that sustainable citizenship—a typically European conception of citizenship that stresses the natural as well as the national world—is an important outcome of these types of educational experiences.
El Metaverso como Medio de Resguardo para los Patrimonios Culturales de la Humanidad
Creators: name: Camargo Rada, Fernando
Publisher: name: Zenodo
Year: 2024

description: La siguiente investigación explora el potencial del metaverso en la preservación y difusión de patrimonios culturales, un campo que está ganando relevancia a medida que las tecnologías digitales avanzan rápidamente. Los metaversos, como The Sandbox y Descentraland, permiten la creación de réplicas digitales de cualquier elemento tangible o intangible del mundo real, ofreciendo una solución innovadora para su protección contra amenazas físicas y su democratización del acceso. Estas plataformas no solo facilitan experiencias educativas y turísticas inmersivas, sino que también abren nuevas vías de financiamiento a través de la comercialización de artefactos digitales como NFTs.Además, la investigación aborda la estrategia de Meta, que a pesar de no contar con un metaverso propio comparable a los ya mencionados, ha invertido significativamente en tecnologías de realidad aumentada (AR), realidad virtual (VR) y realidad mixta (MR) mediante Meta Spark AR. Este enfoque sugiere una futura integración del metaverso en el mundo real, transformando espacios físicos en entornos interactivos accesibles a través de dispositivos móviles, y cómo esta innovación puede ser aprovechada para la preservación patrimonial.Se destaca que la preservación de patrimonios culturales mediante el metaverso no es únicamente una cuestión tecnológica, sino también de voluntad política, compromiso social y responsabilidad cultural. La colaboración entre organizaciones culturales, tecnológicas y educativas será crucial para maximizar los beneficios de estas tecnologías y asegurar la accesibilidad y autenticidad de las experiencias patrimoniales digitales.

description: The ${\ell}^1$-convolution algebra of a semilattice is known to have trivial cohom ology in degrees 1,2 and 3 whenever the coefficient bimodule is symmetric. We ex tend this result to all cohomology groups of degree $\geq 1$ with symmetric coef ficients. Our techniques prove a stronger splitting result, namely that the spli tting can be made natural with respect to the underlying semilattice.

Archival VLBA observations of the Cygnus A Nuclear Radio Transient (Cyg A-2) Strengthen the Tidal Disruption Event Interpretation

description: We have analyzed archival VLBA data for Cygnus A between 2002 and 2013, to search for radio emission from the transient discovered in 2015 by \citet{per18} approximately 0.4\arcsec~ from the nucleus of Cygnus A (Cyg A-2). \citet{per18} use VLA and VLBA archival data (between 1989 and 1997) to show that the transient rises in flux density by a factor of at least five in less than approximately 20 years. With the additional data presented here, we revise the rise time to between approximately four years and six years, based on a new detection of the source at 15.4 GHz from October 2011. Our results strengthen the interpretation of Cyg A-2 as the result of a Tidal Disruption Event (TDE), as we can identify the location of the compact object responsible for the TDE and can estimate the angular expansion speed of the resulting radio emitting structures, equivalent to an apparent expansion speed of $<0.9c$. While our results are consistent with recent X-ray analyses, we can rule out a previously suggested date of early 2013 for the timing of the TDE. We favour a timing between early 2009 and late 2011. Applying the model of \citet{nak11}, we suggest a TDE causing a mildly relativistic outflow with a (density-dependent) total energy $>10^{49}$ erg. Due to the improved temporal coverage of our archival measurements, we find that it is unlikely that Cyg A-2 has previously been in a high luminosity radio state over the last 30 years.

Tre fitonimi per il DESN: 'cetro', 'cetrulo' e 'cetrulillo'
Creators: name: Guarino, Duilia Giada

Year: 2023

description: Il contributo analizza tre voci di ambito botanico da pubblicare sul DESN, precedute da una breve introduzione: cetro, cetrulo e cetrulillo. Le voci provengono dal latino CĬTRUS e si presentano di genere neutro alternante. Cetro e cetrulo sono attestate in napoletano a partire dal XIII secolo (Regimen Sanitatis). La prima voce presentata in questo studio, cetro, designa sia la pianta che il frutto del cedro, come il corrispondente italiano cedro. Di cetrulo, propriamente ‘cetriolo’, si illustrano nel commento alla voce i vari significati traslati e la ricca fraseologia in cui occorre. Infine, il diminutivo cetrulillo, attestato in napoletano a partire dal XVIII secolo con il significato ‘cetriolino’, designa anche altre specie botaniche (come il cocomero asinino). Le tre voci presentate mettono in luce una caratteristica della fitonimia dialettale, cioè l’assenza di biunivocità tra referente botanico e nome dialettale.

description: Στην εργασία αυτή δίνεται αρχικά η έννοια του ισομορφισμού δυο σχεδιασμών και παρατίθενται στη συνέχεια οι αλγόριθμοι εκείνοι που ελέγχουν τους ισομορφισμούς αυτούς. Παρουσιάζονται οι μέθοδοι των Taguchi και Wu και Chen για το σχεδιασμό των γραμμικών γραφημάτων των πειραμάτων, των οποίων ορισμένες αλληλεπιδράσεις μπορεί να είναι σημαντικές. Επίσης, συγκρίνονται οι δύο αυτές μέθοδοι αναφέροντας τα πλεονεκτήματα και τα μειονεκτήματα καθεμιάς απ’ αυτές. Στη συνέχεια, περιγράφεται η μέθοδος των Chen, Sun και Wu και αυτή των Liu, Yang και Liu. Οι δύο αυτές μέθοδοι στηρίζονται στο γεγονός ότι υπάρχουν περιπτώσεις όπου μπορούν να βρεθούν καλύτεροι σχεδιασμοί από αυτούς της ελάχιστης απόκλισης και της μέγιστης αναλυτικής ισχύος.
description: In this thesis the meaning of the design isomorphism is given and the algorithms for testing the graph isomorphism are provided. The Taguchi’s and the Wu and Chen’s methods, for planning a fractional factorial experiment are described, in the case when some interactions are potentially important and should therefore be estimated free of main effects. These two methods are also compared in order to find out the advantages and disadvantages of each of them. Furthermore, two other methods, one of Chen, Sun and Wu and another of Liu, Yang and Liu, are described. As argued in these two methods, there are situations in which better designs can be found than those of the minimum aberration and the maximum resolution.

description: We conduct minimal-channel direct numerical simulations of turbulent flow over two-dimensional rectangular bars aligned in the spanwise direction. This roughness has been often described as $d$-type, as the roughness function $ΔU^+$ is thought to depend only on the outer-layer length scale (pipe diameter, channel half height or boundary layer thickness). This is in contrast to conventional engineering rough surfaces, named $k$-type, for which $ΔU^+$ depends on the roughness height, $k$. The minimal-span rough-wall channel is used to circumvent the high cost of simulating high Reynolds number flows, enabling a range of bars with varying aspect ratios to be investigated. The present results show that increasing the trough-to-crest height ($k$) of the roughness while keeping the width between roughness bars, $\mathcal{W}$, fixed in viscous units, results in non-$k$-type behaviour although this does not necessarily indicate $d$-type behaviour. Instead, for deep surfaces with $k/\mathcal{W}\gtrsim 3$, the roughness function appears to depend only on $\mathcal{W}$ in viscous units. In these situations, the flow no longer has any information about how deep the roughness is and instead can only `see' the width of the fluid gap between the bars.

What is "system": the information-theoretic arguments
Creators: name: Dugic, M.

Publisher: name: arXiv
Year: 2006
Subjects: subject: Quantum Physics (quant-ph)

description: The problem of "what is 'system'?" is in the very foundations of modern quantum mechanics. Here, we point out the interest in this topic in the information-theoretic context. E.g., we point out the possibility to manipulate a pair of mutually non-interacting, non-entangled systems to employ entanglement of the newly defined '(sub)systems' consisting the one and the same composite system. Given the different divisions of a composite system into "subsystems", the Hamiltonian of the system may perform in general non-equivalent quantum computations. Redefinition of "subsystems" of a composite system may be regarded as a method for avoiding decoherence in the quantum hardware. In principle, all the notions refer to a composite system as simple as the hydrogen atom.

description: The SEIR model is a compartmental model used to simulate the dynamics of an epidemic. In this chapter, we introduce two control functions in the compartmental SEIR model representing vaccination and plasma transfusion. Optimal control problems are proposed to study the effects of these two control measures, on the reduction of infected individuals and increase of recovered ones, with minimal costs. Up to our knowledge, the plasma transfusion treatment has never been considered as a control strategy for epidemics mitigation. The proposed vaccination and treatment strategies may have a real application in the challenging and hard problem of controlling the COVID-19 pandemic.
