Supertubes in Matrix model and DBI action

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

description: We show the equivalence between the supertube solutions with an arbitrary cross section in two different actions, the DBI action for the D2-brane and the matrix model action for the D0-branes. More precisely, the equivalence between the supertubes in the D2-brane picture and the D0-brane picture is shown in the boundary state formalism which is valid for all order in α'. This is an application of the method using the infinitely many D0-branes and anti-D0-branes which was used to show other equivalence relations between two seemingly different D-brane systems, including the D-brane realization of the ADHM construction of instanton. We also apply this method to the superfunnel type solutions successfully.

Embodying the nation and the political contention: naturalised athletes changing (sportive) nationalism at the Beijing 2022 Olympics

description: During the 2022 Winter Games, China has lined its team up with an unprecedented number of athletes born and raised abroad. The two American-born sportswomen of Chinese descent, Gu Ailing and Zhu Yi, have been in the news spotlight for renouncing their US citizenship to compete under the Chinese flag, thus being caught in the middle of the Sino-US tensions. The article has a twofold purpose: on the one hand, it explores to what extent the US-China rivalry makes athletes pawns in the hands of states that struggle for supremacy; on the other hand, it seeks to show how the emergence of the phenomenon of athletes’ naturalisation may contribute to the creation of a “multicultural nationalism” while leading to a surge of “negative” sportive nationalism, which assumes that the national interest comes at another nation’s expense. The naturalisation of talents is no longer uncommon. Still, the way in which it is increasingly used in the context of the Games to feed the rivalry between states and shape the meaning of national identity is under-explored and therefore worth investigating.

description: We show that the nontwist phenomena previously observed in Hamiltonian systems exist also in time-reversible non-Hamiltonian systems. In particular, we study the two standard collision/reconnection scenarios and we compute the parameter space breakup diagram of the shearless torus. Besides the Hamiltonian routes, the breakup may occur due to the onset of attractors. We study these phenomena in coupled phase oscillators and in non-area-preserving maps.

description: The knowledge of the structure and dynamics of AGB-star atmospheres is crucial to better understand the mass loss. The tomographic method, that relies on the design of spectral masks containing lines forming in given ranges of optical depths in the stellar atmosphere, is an ideal technique for this purpose. It is applied to high-resolution spectro-interferometric VLTI/AMBER observations of the Mira-type AGB star S Ori. First, the interferometric visibilities are extracted at wavelengths contributing to the tomographic masks and fitted to those computed from a uniform disk model. This allows the measurement of the geometrical extent of the atmospheric layer probed by the corresponding mask. Then, we compare the observed atmospheric extension with those measured from available 1D pulsation CODEX models and 3D radiative-hydrodynamics CO5BOLD simulations. We found that while the average optical depths probed by the tomographic masks in S Ori decrease (with $ = -0.45$, $-1.45$, and $-2.45$ from the innermost to the central and outermost layers), the angular diameters of these layers increase, from 10.59 $\pm$ 0.09 mas through 11.84 $\pm$ 0.17 mas, up to 14.08 $\pm$ 0.15 mas. A similar behavior is observed when the tomographic method is applied to 1D and 3D dynamical models. Thus, this study derives, for the first time, a quantitative relation between optical- and geometrical-depth scales when applied to the Mira star S Ori, or to 1D and 3D dynamical models. In the context of Mira-type stars, the knowledge of the link between the optical and geometrical depths opens the way to derive the shock-wave propagation velocity, which can not be directly observed in these stars.

description: Slovak-Hungarian relations have long been burdened by a different view of the common past. While Hungary and Slovakia cooperate as good and reliable partners in international relations and despite friendly relations between their governments, deep-seated tensions between the two nations is regularly displayed when it comes to football matches. The goal of the article is to map the political expressions of relevant actors at mutual football matches. It analyzes in more detail the behavior and political or ideological expressions of national football associations, clubs, players or fans during two international matches between Slovan Bratislava and Ferencvárosi TC (Budapest) in 2022. The conclusions show that the matches were seen by some spectators as an expression of rivalry between Hungarians and Slovaks. Despite the efforts of UEFA, national football federations or the clubs themselves, the spectators presented political attitudes that bore the signs of aggressive nationalism or chauvinism.

description: Cluster states, a special type of highly entangled states, are a universal resource for measurement-based quantum computation. Here, we propose an efficient one-step generation scheme for cluster states in semiconductor quantum dot molecules, where qubits are encoded on singlet and triplet state of two coupled quantum dots. By applying a collective electrical field or simultaneously adjusting interdot bias voltages of all double-dot molecule, we get a switchable Ising-like interaction between any two adjacent quantum molecule qubits. The initialization, the single qubit measurement, and the experimental parameters are discussed, which shows the large cluster state preparation and one-way quantum computation implementable in semiconductor quantum dots with the present techniques.

description: In this paper, we extend Parikh' work to the non-stationary black hole. As an example of the non-stationary black hole, we study the tunnelling effect and Hawking radiation from a Vaidya black hole whose Bondi mass is identical to its mass parameter. We view Hawking radiation as a tunnelling process across the event horizon and calculate the tunnelling probability. We find that the result is different from Parikh's work because $\frac{dr_{H}}{dv}$ is the function of Bondi mass m(v).

description: Analytic software tools and workflows are increasing in capability, complexity, number, and scale, and the integrity of our workflows is as important as ever. Specifically, we must be able to inspect the process of analytic workflows to assess (1) confidence of the conclusions, (2) risks and biases of the operations involved, (3) sensitivity of the conclusions to sources and agents, (4) impact and pertinence of various sources and agents, and (5) diversity of the sources that support the conclusions. We present an approach that tracks agents' provenance with PROV-O in conjunction with agents' appraisals and evidence links (expressed in our novel DIVE ontology). Together, PROV-O and DIVE enable dynamic propagation of confidence and counter-factual refutation to improve human-machine trust and analytic integrity. We demonstrate representative software developed for user interaction with that provenance, and discuss key needs for organizations adopting such approaches. We demonstrate all of these assessments in a multi-agent analysis scenario, using an interactive web-based information validation UI.

description: We study an autocatalytic reaction-diffusion scheme, the Gray-Scott model, when the mixing processes do not homogenize the reactants. Starting from the master equation, we derive the resulting coupled, nonlinear, stochastic partial differential equations that rigorously include the spatio-temporal fluctuations resulting from the interplay between the reaction and mixing processes. The fields are complex and depend on correlated complex noise terms. We implement a novel method to solve for these complex fields numerically and extract accurate information about the system evolution and stationary states under different mixing regimes. Through this example, we show how the reaction induced fluctuations interact with the temporal nonlinearities leading to results that differ significantly from the mean-field (perfectly mixed) approach. This procedure can be applied to an arbitrary non-linear reaction diffusion scheme.

description: Since the end of the 1970s, when it was already preparing for the ‘great opening’, China has sought to legitimize itself before the international community through various strategies, including seeking international recognition in sport and attempting to rapidly extend its influence over transnational sporting institutions by using and combining soft power, national status and the internal development of Olympic disciplines and, in particular, football. Already Deng Xiaoping, a passionate lover of the ‘beautiful game’, after the Cultural Revolution had rehabilitated football and tried to rebuild a Chinese football movement. But it was with the election of Xi Jinping as General Secretary of the Communist Party of China in 2012 that a real strategy was launched to develop Chinese football through structural reforms. Investment, participation and media consumption in football have increased since the implementation of this reform plan and the revitalization of football has become a key strategic objective for China. The continuing failures of the men’s senior national team, scandals – however – and, in recent times, the Covid-19 pandemic with the subsequent downturn in the Asian giant’s economic growth, have brought the contradictions of Chinese football to the surface. Our contribution will attempt to highlight the entanglements that link football to the complex and varied Chinese power system.

description: In this article, we aim to analyze the relationship between the condition of the Kurdish population and the world of Kurdish protest starting from organized football fans' stands, highlighting the territorial connections that go beyond the football dimension and (imposed) borders. In fact, it happens that the stadium stands represent a social space of dissent against the dominant political arrangements (Fedele, 2021; Bifulco and Pirone, 2014) and that in the repression of the Amedspor fans, the metaphor of forced inclusion is realized. To analyze what happens, we consider Kurdistan as an 'international colony' (Beşikçi, 1991), as a nation divided between four different states. For the purpose of conducting our analysis, we will use the "border as a method" (Mezzadra and Neilson, 2013), as, since the border is a legal product that marks an act of power (Spíndola Zago, 2016), it allows us to investigate the power that establishes a hegemony over space.

description: Surfers Paradise presents the findings of an anthropological inquiry into surfing culture. Through participant observation and interviews, Dario Nardini focuses on the collective fascination with surfing in the Australian Gold Coast, dissecting its historical, relational, symbolic, institutional, and sensorial dimensions, as well as its influence on national identity. This paper discusses Nardini’s ethnography as a brilliant “phenomenology of a passion” example. Integrating consolidated debates in social sciences, such as embodiment, the sociology of consumption, the anthropological study of people’s heritage, the anthropology of leisure and games, and the lifestyle studies, the book outlines the complex meaning of surfing in Australia. Above everything, the ethnographic approach provides a powerful lens to investigate sports and physical cultural practices, by examining the body-environment-society interconnections.

description: This article delves into a sociological analysis of the book “La valeur du footballer” of Manuel Schottè, examining the attributed value of football players and the prevalent trend in the soccer world to emphasize individuality over the collective. The author explores interpretations by considering the valorization as a historical product rooted in structural dynamics and context-specific practices. The article further explores football as a space for constructing a status of prominence, the valorization of a minority of players as a symbolic frontier, concentration and circularity of profits, and the individualization of performance and player valorization. Ultimately, the work provides a comprehensive perspective connecting history, social structure, and contemporary dynamics to comprehend the value within football.

Moreover, we extract the explicit form of the jet quenching parameter of medium with small chemical potential for phases of dual SYM corresponding to large and small black holes. For the former phase, the jet quenching is increased as the charge density increases, however, for the latter it is the opposite though the background is thermodynamically unstable.

description: We consider the heavy quark-antiquark potential in the AdS / QCD correspondence, focusing in particular on a recently calculated AdS-like metric deformed by back-reaction effects. We find that tuning the long-distance behaviour of the potential leads to a discrepancy at small distances, and discuss how to better constrain AdS / QCD geometries. A systematic comparison of various geometries is presented, based on goodness of fit to lattice data in the quenched approximation. The back-reacted geometry is seen to be phenomenologically favoured over an alternative geometry with the same number of parameters, although it does not perform as well as some other geometries.

description: Hypopharyngeal cancer is rare subtype of head and neck cancers with relatively poor prognosis. Current therapeutic modalities lack the potential to provide patients with better clinical outcome and quality of life. This study was conducted on the synthesis of 2-methoxy-4-((3-alkyl(aryl)-5-oxo-1H-1,2,4-triazol-4(5H)-ylimino)-methyl)-phenyl-4-(2-methoxy-4-((3-alkyl(aryl)-5-oxo-1H-1,2,4-triazol-4(5H)-ylimino)-methyl)-phenyl)-4-oxobutanoates (3) using biologically important 1,2,4-triazole. The condensation of 3-alkyl(aryl)-4-amino-4,5-dihydro-1H-1,2,4-triazol-5-ones (1) with 4-formyl-2-methoxyphenyl-4-(4-formyl-2-methoxyphenyl)-4-oxobutanoate yielded the biologically active 2-methoxy-4-((3-alkyl(aryl)-5-oxo-1H-1,2,4-triazol-4(5H)-ylimino)-methyl)-phenyl-4-(2-methoxy-4-((3-alkyl(aryl)-5-oxo-1H-1,2,4-triazol-4(5H)-ylimino)-methyl)-phenyl)-4-oxobutanoates (3). The compounds obtained were analyzed via FT-IR,1H-/13C-NMR spectrometers, elemental analysis, and HRMS spectroscopic techniques. Furthermore, we aimed at investigating the potential of compounds 3a-g against FaDu hypopharyngeal cancer cells. We demonstrated that compounds 3c, 3e, and 3 g had relatively lower IC50 values compared to the remaining tested compounds and more importantly their IC50 values were comparable to 5-FU, which suggests them as important therapeutic agent candidates. These newly synthesized compounds were assessed for their inhibitory activities toward two human carbonic anhydrase isoforms I and II (hCA I and II). Then, molecular docking calculations were made to compare the biological activities of studied molecules against cancer proteins. Compound 3c has a docking score of −7.15 against squamous cell carcinoma protein with ID: 2DO4 and −5.49 docking score against squamous cell carcinoma protein with ID:5PJZ. ADME/T analysis was performed to examine the drug properties of studied molecules.

description: Purpose Infectious agents, such as SARS-CoV-2, can be carried by droplets expelled during breathing. The spatial dissemination of droplets varies according to their initial velocity. After a short literature review, our goal was to determine the velocity of the exhaled air during vocal exercises. Methods A propylene glycol cloud produced by 2 e-cigarettes' users allowed visualization of the exhaled air emitted during vocal exercises. Airflow velocities were measured during the first 200 ms of a long exhalation, a sustained vowel /a/ and varied vocal exercises. For the long exhalation and the sustained vowel /a/, the decrease of airflow velocity was measured until 3 s. Results were compared with a Computational Fluid Dynamics (CFD) study using boundary conditions consistent with our experimental study. Results Regarding the production of vowels, higher velocities were found in loud and whispered voices than in normal voice. Voiced consonants like /3/ or /v/ generated higher velocities than vowels. Some voiceless consonants, e.g., /t/ generated high velocities, but long exhalation had the highest velocities. Semi-occluded vocal tract exercises generated faster airflow velocities than loud speech, with a decreased velocity during voicing. The initial velocity quickly decreased as was shown during a long exhalation or a sustained vowel /a/. Velocities were consistent with the CFD data. Conclusion Initial velocity of the exhaled air is a key factor influencing droplets trajectory. Our study revealed that vocal exercises produce a slower airflow than long exhalation. Speech therapy should, therefore, not be associated with an increased risk of contamination when implementing standard recommendations.

description: Wolf-Rayet (WR) stars in the Magellanic Clouds (MCs) are ideal for studying the production of X-ray emission by their strong fast stellar winds. We have started a systematic survey for X-ray emission from WR stars in the MCs using archival Chandra, ROSAT, and XMM-Newton observations. In Paper I, we reported the detection of X-ray emission from 29 WR stars using Chandra ACIS observations of 70 WR stars in the MCs. In this paper, we report the search and analysis of archival ROSAT PSPC and HRI observations of WR stars. While useful ROSAT observations are available for 117 WR stars in the MCs, X-ray emission is detected from only 7 of them. The detection rate of X-ray emission from MCs WR stars in the ROSAT survey is much smaller than in the Chandra ACIS survey, illustrating the necessity of high angular resolution and sensitivity. LMC-WR 101-102 and 116 were detected by both ROSAT and Chandra, but no large long-term variations are evident.

description: The Goldberger-Wise mechanism of stabilizing modulus in the Randall-Sundrum braneworld,by introducing a bulk scalar field with quartic interaction terms localized at the 3-branes has been extremely popular as a stabilizing mechanism when the back-reaction of the scalar field on the geometry is negligibly small. In this note we re-examine the mechanism by an exact analysis without resorting to the approximations adopted by Goldberger and Wise. An exact calculation of the stabilization condition indicates the existence of closely spaced minimum and a maximum for the potential and also brings out some new features involved in the context of stabilization of such braneworld models.

description: We demonstrate detection of NaRb Feshbach molecules at high magnetic field by combining molecular photodissociation and absorption imaging of the photofragments. The photodissociation process is carried out via a spectroscopically selected hyperfine Zeeman level correlated with the Na ($3P_{3/2}$) + Rb ($5S_{1/2}$) asymptote which, following spontaneous emission and optical pumping, leads to ground-state atoms in a single level with near unity probability. Subsequent to the dissociation, the number of molecules is obtained by detecting the resultant $^{23}$Na and $^{87}$Rb atoms. We have also studied the heating effect caused by the photodissociation process and optimized the detection protocol for extracting the temperature of the molecular cloud. This method enables the $in~situ$ detection of fast time scale collision dynamics between NaRb Feshbach molecules and will be a valuable capability in studying few-body physics involving molecules.

Per una sociologia della performing art. Il valore strategico delle opere di Alessandro Sciarroni
Creators: name: De Feo, Linda
Publisher: name: Eracle. Journal of Sport and Social Sciences
Year: 2023

description: The object of reflection will be the strategic value of the performing art of Alessandro Sciarroni, an internationally recognised author. Using practices borrowed from the spheres of dance, sport and circus, the artist, through unusual cultural instrumentations and emotional configurations, represents the masterfully deconstructed relationship between identity and otherness. This paper raises the following question: can terpsichorean art and sporting activity be capable of demolishing categories devalued by the norm, aimed at reaffirming the dominant socio-cultural Self? The argumentation concerns the capacity of both spheres to redelineate and reconceptualise not only on an aesthetic level the dynamics connected to introspective withdrawals, shared rituals and different abilities. The examination of some Sciarroni’s works will trace a research pathway.

description: The paper is concerned with an adjoint complement to the Volume-of-Fluid (VoF) method for immiscible two-phase flows, e.g. air and water, which is widely used in marine engineering due to its computational efficiency. The particular challenge of the primal and the corresponding adjoint VoF-approach refers to the sharp interface treatment featuring discontinuous physical properties. Both the continuous adjoint two-phase system (integration-by-parts) and the corresponding dual compressive convection schemes (summation-by-parts) are derived for two prominent compressive convection schemes, namely the High Resolution Interface Capturing Scheme (HRIC) and Compressive Interface Capturing Scheme for Arbitrary Meshes (CICSAM). The dual scheme rigorously mirrors the primal Normalized-Variable-Diagram (NVD) stencils. Attention is restricted to steady state applications. Thus both the primal and the dual procedures are performed in pseudo time and the backward integration of the dual approach is performed around the (pseudo-temporal) converged primal field. The paper analyses the primal and adjoint equations for an engineering model problem. An analytical solution to the model problem is initially presented, which displays that the adjoint part does not offer a unique, non-trivial solution. As a remedy, an additional diffusive concentration term is introduced to the adjoint concentration equation. Numerical results obtained from the modified approach are benchmarked against the analytical solution for the model problem. Supplementary, the influence of the modification on the sensitivities obtained from simulations for the two-dimensional flow around a submerged hydrofoil are discussed. The final application refers to a shape-optimization of a generic 3D underwater vehicle and underlines a negligible influence of the free mobility parameter.

description: Recent site testing (see: http://www-luan.unice.fr/Concordiastro/indexantartic.html) has shown that Dome C in Antarctica might have a high potential for stellar interferometry if some solutions related to the surface atmospheric layer are found. A demonstrator interferometer could be envisioned in order to fully qualify the site and prepare the future development of a large array. We analyse the performances of a prototype interferometer for Dome C made with 3 telescopes of 40 cm diameter. It assumes classical Michelson recombination. The most recent atmospheric and environmental conditions measured at Dome C are considered (see K. Agabi "First whole atmosphere night-time seeing measurements at Dome C, Antarctica"). We also study the possible science reachable with such a demonstrator. Especially we evaluate that even such small aperture interferometer could allow the detection and low resolution spectroscopy of the most favourable pegaside planets.

Sport activities and EDs
Creators: name: Corvino, Isabella

description: The aim of these articles is to approach the theme of Eating Disorders (EDs) connected with sport activities. Sports activity remains an open field: it is not in itself didactic nor does it necessarily represent a positive experience. In sport, themes such as identity, relationships, health, are strictly bonded to self-realization, social pressure on performance and desirable beauty standards; this partially poisoned the sport environment. The spectacularized and consumerist form of these activities - mostly linked to social distress and the communication world -, the way to perfection storytelling can sometimes bring out disorders or even there can be the case in which people use sport to hide the disorder behind strict health protocols. We need to focus a more cautious look on sport so that it can be filled with positive meanings linked to the emancipation of oneself, to a playful dimension as fun and pleasure, to educational paths, free expression and equality.

description: Open Clusters (OCs) can trace with a great accuracy the evolution of the Galactic disk. The aim of this work is to study the kinematical behavior of the OC population over time. We take advantage of the latest age determinations of OCs to investigate the correlations of the 6D phase space coordinates and orbital properties with age. We also investigate the rotation curve of the Milky Way traced by OCs and we compare it to that of other observational or theoretical studies. We gathered nearly 30000 Radial Velocity (RV) measurements of OC members from both Gaia-RVS data and ground based surveys and catalogues. We computed the weighted mean RV, Galactic velocities and orbital parameters of 1382 OCs. We investigated their distributions as a function of age, and by comparison to field stars. We provide the largest RV catalogue available for OCs, half of it based on at least 3 members. Compared to field stars, we note that OCs are not exactly on the same arches in the radial-azimuthal velocity plane, while they seem to follow the same diagonal ridges in the Galactic radial distribution of azimuthal velocities. Velocity ellipsoids in different age bins all show a clear anisotropy. The heating rate of the OC population is similar to that of field stars for the radial and azimuthal components but significantly lower for the vertical component. The rotation curve drawn by our sample of clusters shows several dips, which match the wiggles derived from non-axisymmetric models of the Galaxy. From the computation of orbits, we obtain a clear dependence of the maximum height and eccentricity with age. Finally, the orbital characteristics of the sample of clusters as shown by the action variables, follow the distribution of field stars. The additional age information of the clusters points towards some (weak) age dependence of the known moving groups.

description: We study experimentally the dynamics of long waves among turbulent bending waves in a thin elastic plate set into vibration by a monochromatic forcing at a frequency $f_0$. This frequency is chosen large compared with the characteristic frequencies of bending waves. As a consequence, a range of conservative scales, without energy flux in average, exists for frequencies $f

description: Σκοπός της διπλωματικής εργασίας είναι η μελέτη του πρώτου μέρους της Κριτικής της κριτικής Δύναμης του Immanuel Kant που αφορά στην έννοια της αισθητικής κριτικής δύναμης. Στην εισαγωγή αναλύεται το σύστημα της φιλοσοφίας, το οποίο περιέχει αρχές της έλλογης γνώσης και απαρτίζεται από δύο διακριτά μεταξύ τους μέρη, τη θεωρητική και την πρακτική φιλοσοφία. Επίσης, αναλύεται ο χαρακτήρας της γνωστικής ικανότητας της κριτικής δύναμης προσδιορίζοντας την αρχή που διέπει τη λειτουργία της, η οποία είναι η αρχή της σκοπιμότητας της φύσης. Στο κεφάλαιο της αναλυτικής του ωραίου διερευνάται η υποκειμενική μορφική σκοπιμότητα ενός αντικειμένου ως στοιχείο καταλληλότητας του αντικειμένου για τις γνωστικές δυνάμεις όταν αυτές ενεργοποιούνται κατά τον αναστοχασμό της κριτικής δύναμης με το αίσθημα της ευαρέσκειας. Στο κεφάλαιο της αναλυτικής του υψηλού η έρευνα εστιάζεται στη λειτουργία της φαντασίας κατά την αναστοχαστική πρόσληψη και παράδειξη μίας μορφής. Έτσι, Το υψηλό εξετάζεται ως προς τις δύο μορφές υπό τις οποίες παρουσιάζονται τα αντικείμενα στη φαντασία δηλαδή το μαθηματικό υψηλό και το δυναμικό υψηλό. Στο κεφάλαιο της παραγωγής των καθαρών αισθητικών κρίσεων αναλύεται η νομιμοποίηση του ισχυρισμού των αισθητικών κρίσεων για καθολική εγκυρότητα και αναγκαιότητα. Τέλος, εξετάζεται η φύση του έργου τέχνης και της ιδιοφυίας, η άμεση σχέση μεταξύ κριτικής δύναμης και ιδιοφυίας όπως, επίσης, η σχέση μεταξύ καλαισθησίας και καλλιτεχνικής δημιουργίας.
description: The aim of this thesis is the study of the first part of the Critique of aesthetic judgment of Immanuel Kant. The introduction explains the system of philosophy, which contains principles of rational knowledge which consists of two distinct parts with each other, the theoretical and practical philosophy. Also, it is analyzed the nature of the cognitive ability of critical judgment by establishing the principle behind its operation, which is the principle of nature’s purposiveness. In the section of the analytic of the beautiful it is investigated the morphological subjective purposiveness of an object as compatible with the cognitive powers when they are activated by the power of critical reflection. In the section of the analytic of the sublime, the research focuses on the reflective and representative function of imagination on a form. Thus, the sublime it is considered under the two forms in which objects are presented to the imagination, the mathematical sublime and the potential sublime. In the deduction of pure aesthetic judgments it is analyzed the legitimacy of the claim of aesthetic judgments about their universal validity and necessity. Finally, it is examined the nature of a work of art and genius, the direct relationship between critical judgment and genius as also the relationship between judgment of taste and artistic creation.

description: Mainly referred to the combinations of sportswear in daily life, athleisure (a crasis of the terms athletic and leisure) has enormously spread in Western society during the recent years of the pandemics and it has become a growing economic sector, which has been studied from a prominently marketing perspective. The article will provide a more accurate and complex insight of the phenomenon from a cultural perspective, focusing on the ways in which the cultural representation of the active athletic body is materialized via athleisure, intertwined with gender identity, and embodied in everyday practice.

description: The interaction of mass-selected atomic clusters and nanoparticles with surfaces attracts strong interest in view of fundamental research and technological applications. Understanding dynamics of the deposition process is important for controlling structure and functioning of deposited nanoparticles on a substrate, but experimental techniques can usually observe only the final outcome of the deposition process. In this paper, the deposition of 4 nm-sized sodium nanoparticles on an experimentally relevant magnesium oxide substrate is studied by means of classical molecular dynamics simulations. An empirical force field is derived which accounts for the interaction of highly polarizable Na atoms with the surface, reproducing the results of previously reported quantum mechanics/molecular mechanics simulations. Molecular dynamics simulations permit exploring the dynamics of deposited nanoparticles on long timescales on the order of hundreds of picoseconds, thus enabling the analysis of energy relaxation mechanisms and the evolution of nanoparticle structure up to its thermalization with the substrate. Several nanoparticle characteristics, such as internal structure, contact angle, and aspect ratio are studied in a broad deposition energy range from the soft landing to multi-fragmentation regimes.
