description: We investigate the flow around an oscillating nearly-spherical particle at low, yet non-vanishing, Reynolds numbers, and the potential resulting locomotion. We analytically demonstrate that no net motion can arise up to order one in Re and order one in the asphericity parameter, regardless of the particle's shape. Therefore, geometry-induced acoustic streaming propulsion, if any, must arise at higher order.

description: The increasing demand for orthodontic treatment among adults in the modern digital age has brought to light a unique set of challenges. Many adult patients require orthodontic intervention as part of their journey towards improved aesthetics and oral rehabilitation. Oftentimes, the final restoration is postponed until after orthodontic treatment, necessitating the bonding of brackets to provisional crowns for an extended period. This bonding process is notably more challenging when compared to bonding brackets to natural teeth.

In this context, the provisional crowns on which brackets are affixed must exhibit superior physical and mechanical properties, with the ability to withstand occlusal and orthodontic forces. Furthermore, they should offer enhanced handling, improved aesthetics, and compatibility with oro-dental tissues. These provisional crowns can be either prefabricated or custom-made from various materials, including traditional polycarbonate and auto-polymerizing polymethylmethacrylate (PMMA) resins. Recent advances have introduced new materials like computer-aided design/computer-aided manufacturing (CAD/CAM) PMMA and bis-acryl resins for provisional crown fabrication.

The critical step in the orthodontic treatment process is the bonding of orthodontic brackets to these provisional crowns, as direct bonding often results in poor bond strength. This prompts the need for surface treatment methods to enhance the bond strength of these brackets
Anomalous scaling in two models of the passive scalar advection: Effects of anisotropy and compressibility

Subjects: subject: Chaotic Dynamics (nlin.CD)
subject: FOS: Physical sciences

description: The problem of the effects of compressibility and large-scale anisotropy on anomalous scaling behavior is considered for two models describing passive advection of scalar density and tracer fields. The advecting velocity field is Gaussian, $δ$-correlated in time, and scales with a positive exponent $ε$. Explicit inertial-range expressions for the scalar correlation functions are obtained; they are represented by superpositions of power laws with nonuniversal amplitudes and universal (dependent only on $ε$ and $α$, the compressibility parameter) anomalous exponents. The complete set of anomalous exponents for the pair correlation functions is found nonperturbatively, in any space dimension d, using the zero-mode technique. For higher-order correlation functions, the anomalous exponents are calculated to $O(ε^{2})$ using the renormalization group. Like in the incompressible case, the exponents exhibit a hierarchy related to the degree of anisotropy: the leading contributions to the even correlation functions are given by the exponents from the isotropic shell, in agreement with the idea of restored small-scale isotropy. As the degree of compressibility increases, the corrections become closer to the leading terms. The small-scale anisotropy reveals itself in the odd ratios of correlation functions: the skewness factor is slowly decreasing going down to small scales for the incompressible case, but becomes increasing if $α$ is large enough. The higher odd dimensionless ratios (hyperskewness etc.) increase, thus signalling the persistent small-scale anisotropy; this effect becomes more pronounced for larger values of $α$.

description: We study the forms of the orbits in a symmetric configuration of a realistic model of the H2O molecule with particular emphasis on the periodic orbits. We use an appropriate Poincaré surface of section (PSS) and study the distribution of the orbits on this PSS for various energies. We find both ordered and chaotic orbits. The proportion of ordered orbits is almost 100% for small energies, but decreases abruptly beyond a critical energy. When the energy exceeds the escape energy there are still non-escaping orbits around stable periodic orbits. We study in detail the forms of the various periodic orbits, and their connections, by providing appropriate stability and bifurcation diagrams.

description: This paper presents a new specific system based on RFID technology to help blind people find the other party in their meeting place. This system, uses a device called Smart Director or SD, equipped with Active Tag and RFID Reader. The blind person, the visitor, adjusts the SD with the identification number of the other party who has shared it previously for example on a telephone call, and takes the device to the meeting place. When the blind person arrives at the location, the reader of the device receives signals from the active tag of the other party's SD. It then identifies his/her position based on the intensity and direction of the received signals and tell it to the blind person. In this way, blind people can simply identify the position of the other party in crowded places and find each other.

description: The surface impedance Z(f) of conventional isotropic materials has been carefully measured for frequencies f ranging from 1 kHz to 3 MHz, allowing a detailed investigation of the depinning transition. Our results exhibit the irrelevance of classical ideas to the dynamics of vortex pinning. We propose a new picture, where the linear ac response is entirely governed by disordered boundary conditions of a rough surface, whereas in the bulk vortices respond freely. The universal law for Z(f) thus predicted is in remarkable agreement with experiment, and tentatively applies to microwave data in YBaCuO films.

description: Learning from data has led to a paradigm shift in computational materials science. In particular, it has been shown that neural networks can learn the potential energy surface and interatomic forces through examples, thus bypassing the computationally expensive density functional theory calculations. Combining many-body techniques with a deep learning approach, we demonstrate that a fully-connected neural network is able to learn the complex collective behavior of electrons in strongly correlated systems. Specifically, we consider the Anderson-Hubbard (AH) model, which is a canonical system for studying the interplay between electron correlation and strong localization. The ground states of the AH model on a square lattice are obtained using the real-space Gutzwiller method. The obtained solutions are used to train a multi-task multi-layer neural network, which subsequently can accurately predict quantities such as the local probability of double occupation and the quasiparticle weight, given the disorder potential in the neighborhood as the input.

description: A D3-brane probe in the context of AdS/CFT correspondence at finite temperature is considered. The supergravity predictions for the physical effective couplings of the world-volume gauge theory of the probe brane are compared to those calculated in one-loop perturbation theory in the thermal gauge theory. It is argued that when the Higgs expectation value is much larger than the temperature, the supergravity result must agree with perturbative thermal Yang-Mills. This provides a perturbative test of the Maldacena conjecture. Predictions for the running electric and magnetic effective couplings, beyond perturbation theory are also obtained. Phenomenological applications for universe-branes are discussed. In particular mechanisms are suggested for reducing the induced cosmological constant and naturally obtaining a varying speed of light and a consequent inflation on the universe brane.

description: Auch hundert Jahre nach Max Webers Tod können Kommunikationswissenschaft und Journalismus noch von ihm lernen: Sein grundlegender Begriff des sozialen Handelns stützt Legitimität und Chancen realistischer Medienkritik; sein Konzept einer großen Presse-Erhebung blickt umfassender auf öffentliche Kommunikationsprozesse als spätere Formeln und Modelle; seine Ethik-Vorstellungen fördern eine zivilisierte Grundhaltung des Abwägens in Politik, Wissenschaft und Journalismus; seine auf Rationalitätsbegriffe fixierte Typologie von Handlungsweisen regt zu einer Erweiterung an, die Grundprobleme sozialer Selbstregulierung besser erkennbar werden und u. a. auch durch nachhaltige Medienkommunikation lösbar erscheinen lässt; und sein Konzept einer verstehenden Soziologie weist ein halbes Jahrhundert vor Habermas auf die praktische Bedeutung des Erkenntnisinteresses an Verständigung hin, dem historisch-hermeneutische Disziplinen zu dienen haben. Die Argumentation verfolgt die These, dass der Wert eines Klassikers wie Max Weber vor allem darin liegt, bei fortschreitender Ausdifferenzierung und Parzellierung auch der (Kommunikations‑)Wissenschaft selbst den Blick für gesellschaftliche Zusammenhänge von Medienphänomenen nicht zu verlieren.
description: Even a hundred years after Max Weber’s death, communication studies and journalism can still learn from him: his fundamental notion of social action supports the legitimacy and chances of realistic media criticism; his concept of a large press survey looks more comprehensively at public communication processes than later formulas and models; his ideas on ethics promote a civilized basic attitude of weighing up in politics, science and journalism; his typology of modes of action, which is based on concepts of rationality, encourages an expansion, which makes the basic problems of social self-regulation more easily recognizable and, among other things, allows for a better understanding of the social potential of the media; and his concept of an understanding sociology half a century before Habermas points to the practical significance of the cognitive interest in understanding, which historical-hermeneutic disciplines have to serve. The argumentation is based on the thesis that the value of a classic such as Max Weber lies above all in the fact that his work, with ongoing differentiation and parcelling out of even the (communication) sciences themselves does not lose sight of the social connections of media phenomena.

description: The photometric light curve of PG1302-102 shows periodic variability which makes this object one of the most plausible supermassive black hole binary candidate. Interestingly, the most recent study of its updated optical light curve reports a decrease in significance of periodicity which may suggest that the binary model is less favorable. Here, we model the PG 1302-102 light curve, spanning almost 20 years, with a supermassive black hole binary system in which a perturbation in the accretion disk of more massive component is present. Our model reproduces well the observed light curve with a slight perturbation of a sinusoidal feature and predicts that a slightly larger period than previously reported, of about 1899 days, could arise due to a cold spot in the disk of {\bf more massive} component of a close, unequal-mass ($\frac{\mathrm{m}_{1}}{\mathrm{m}_{2}}=0.1$) black hole binary system. The light curve resembles the pattern of sinusoid-like shape within a few years, which could be confirmed by future observations. In addition, using our hybrid method for periodicity detection, we show that the periods in the observed ($1972\pm 254$ days) and modeled ($1873 \pm \ 250$ days) light curves are within one-sigma, which is also consistent with our physical model prediction and with previous findings. Thus, both the periodic nature and its slight fluctuation of the light curve of PG1302-102 is evident from our physical model and confirmed by the hybrid method for periodicity detection.

description: We examine the Wheeler-DeWitt equaton for a static, eternal Schwarzschild black hole in Kucha\v r-Brown variables and obtain its energy eigenstates. Consistent solutions vanish in the exterior of the Kruskal manifold and are non-vanishing only in the interior. The system is reminiscent of a particle in a box. States of definite parity avoid the singular geometry by vanishing at the origin. These definite parity states admit a discrete energy spectrum, depending on one quantum number which determines the Arnowitt-Deser-Misner (ADM) mass of the black hole according to a relation conjectured long ago by Bekenstein, $M \sim \sqrt{n}M_p$. If attention is restricted only to these quantized energy states, a black hole is described not only by its mass but also by its parity. States of indefinite parity do not admit a quantized mass spectrum.

Το αναλυτικό πλαίσιο της διδακτορικής διατριβής είναι η δημιουργία ενός σύνθετου δείκτη. Ο δείκτης που οικοδομήθηκε είναι ο Σύνθετος Δείκτης Επίδρασης του Νομισματικού Ανταγωνισμού.

Ουσιαστικά, η κύρια υπόθεση της διατριβής είναι ότι οι επιδράσεις του νομισματικού ανταγωνισμού καθορίζονται από τον συνδυασμό των πολιτικό - οικονομικών και διεθνών παραγόντων κάθε χώρας και η ένταση της επίδρασης του νομισματικού ανταγωνισμού προσδιορίζεται από τον παραπάνω συνδυασμό.

description: The dynamics of soliton and quasisoliton solutions of cubic third order nonlinear Schrödinger equation is studied. The regular solitons exist due to a balance between the nonlinear terms and (linear) third order dispersion; they are not important at small $α_3$ ($α_3$ is the coefficient in the third derivative term) and vanish at $α_3 \to 0$. The most essential, at small $α_3$, is a quasisoliton emitting resonant radiation (resonantly radiating soliton). Its relationship with the other (steady) quasisoliton, called embedded soliton, is studied analytically and in numerical experiments. It is demonstrated that the resonantly radiating solitons emerge in the course of nonlinear evolution, which shows their physical significance.

description: College affordability is vital to college access and success. The college affordability issue is very salient in the context of Texas higher education, particularly at four-year public institutions because of tuition increases caused by tuition deregulation since 2003. Although students primarily utilize federal aid to reduce the cost of college education, state-level financial aid also plays a critical role in shaping college affordability for all students but especially low-income students. However, extant research does not offer clear evidence of how state-supported financial aid affects student outcomes in Texas, particularly for offsetting college costs. As a result, policy debates over the value of state-supported financial aid at the state capitol are missing key empirical evidence. Using statewide administrative data from the Texas Education Research Center and applied longitudinal data analytic methods, this study investigates how state-supported financial aid impacts baccalaureate degree completion and whether the effects vary across income status and race. Conceptualizing that the chances of graduation heavily depend on financial support as well as individual ability to pay for college and assuming that the impact of student aid on degree completion is not uniform but varies across different groups of students by income status and race, this study seeks to answer two research questions: (1) How does state-supported financial aid, broken down by programs of financial aid, impact baccalaureate degree completion? (2) How do the effects of state-supported financial aid on baccalaureate degree completion vary across income status and race? Results from various analyses on the sample of first-time, resident students who began in Texas’ public four-year institutions in 2011-2012 bolster support for the student responsiveness literature emphasizing the role state-supported financial aid can play in promoting students’ baccalaureate degree completion. Findings also show variation in the effects of state-supported financial aid on baccalaureate degree completion across programs and student characteristics such as income status and race. The findings suggest that it is necessary to explore effective strategies to increase student outcomes and reduce the inequality in educational opportunity across students by utilizing financial aid where in theory the chances of graduation heavily depend on financial resources to pay for college. Ultimately, the role of state-supported financial aid coupled with other financial resources is vital to ensure college affordability and student success in an era of rising costs of higher education in Texas.

description: The investigation of vascular calcification and its underlying cellular and molecular pathways is of great interest in current research efforts. Therefore, suitable assays are needed to allow examination of the complex calcification process under controlled conditions. The current study describes a new ex vivo model of isolated-perfused rat aortic tissue with subsequent quantification and vessel staining to analyze the calcium content of the aortic wall. A rat aorta was perfused ex vivo with control and calcification media for 14 days, respectively. The calcification medium was luminally perfused and induced a significant increase in calcium deposition within the media of the vessel wall detected alongside the elastic laminae. Perfusion with control medium induced no calcification. In addition, the mRNA expression of the osteogenic marker bone morphogenetic protein 2 (BMP-2) increased in aortic tissue after perfusion, while SM22α as smooth muscle marker decreased. This newly developed ex vivo model of isolated-perfused rat aorta is suitable for vascular calcification studies testing inducers and inhibitors of vessel calcification and studying signaling pathways within calcification progression.

Magnetic loops above a small flux-emerging region observed by IRIS, Hinode and SDO

description: I report on observations of a set of magnetic loops above a region with late-phase flux emergence taken by IRIS, Hinode and SDO. The loop system consists of many transition region loop threads with size of 5--12\arcsec\ in length and $\sim0.5$\arcsec in width and coronal loops with similar length and $\sim2$\arcsec width. Although the loop system consists of threads with different temperatures, most individual loop thread have temperature in a narrow range. In the middle of the loop system, it shows clear systematic blue-shifts of about 10\,\kms\ in the transition region that is consistent with a flux emerging picture, while red-shifts of about 10\,\kms\ in the corona is observed. The nonthermal velocity of the loop system are smaller than the surrounding region in the transition region but are comparable in the corona. The electron densities of the coronal counterpart of the loop system range from $1\times10^9$\,cm$^{-3}$ to $4\times10^9$\,cm$^{-3}$. Electron density of a transition region loop is also measured and found to be about $5\times10^{10}$\,cm$^{-3}$, a magnitude larger than that in the coronal loops. In agreement with imaging data, the temperature profiles derived from the differential emission measurement technique confirms that some of the loops have been heated to corona. Our observations indicate that the flux emergence in its late phase is much different from that at the early stage. While the observed transition region is dominated by emerging flux, these emerging loops could be heated to corona and the heatings (if via nonthermal processes) most likely take place only after they reaching the transition region or lower corona.

description: Through a mechanism similar to perturbative particle scattering, particles of mass $m_χ$ larger than the Hubble expansion rate $H_\mathrm{inf}$ during inflation can be gravitationally produced at the end of inflation without the exponential suppression powers of $\exp(-m_χ/H_\mathrm{inf})$. Here we develop an analytic formalism for computing particle production for such massive particles. We apply our formalism to specific models that have been previously been studied only numerically, and we find that our analytical approximations reproduce those numerical estimates well.

description: Quasiparticle states bound to the boundary of anisotropically paired superconductors, their contributions to the density of states and to the conductance of NIS junctions are studied both analytically and numerically. For smooth surfaces and real order parameter we find some general results for the bound state energies. In particular, we show that under fairly general conditions quasiparticle states with nonzero energies exist for momentum directions within a narrow region around the surface normal. The energy dispersion of the bound states always has an extremum for the direction along the normal. Along with the zero-bias anomaly due to midgap states, we find, for quasi two-dimensional materials, additional low-temperature peaks in the conductance of NIS junctions for voltages determined by the extrema of the bound state energies. The influence of interface roughness on the conductance is investigated within the framework of Ovchinnikov's model. We show that nonzero-bias peaks at low temperatures may give information on the order parameter in the bulk, even though it is suppressed at the surface.

description: Non-singular two and three dimensional string cosmologies are constructed using the exact conformal field theories corresponding to SO(2,1)/SO(1,1) and SO(2,2)/SO(2,1). All semi-classical curvature singularities are canceled in the exact theories for both of these cosets, but some new quantum curvature singularities emerge. However, considering different patches of the global manifolds, allows the construction of non-singular spacetimes with cosmological interpretation. In both two and three dimensions, we construct non-singular oscillating cosmologies, non-singular expanding and inflationary cosmologies including a de Sitter (exponential) stage with positive scalar curvature as well as non-singular contracting and deflationary cosmologies. We analyse these cosmologies in detail with respect to the behaviour of the scale factors, the scalar curvature and the string-coupling. The sign of the scalar curvature is changed by the quantum corrections in oscillating cosmologies and evolves with time in the non-oscillating cases. Similarities between the two and three dimensional cases suggest a general picture for higher dimensional coset cosmologies: Anisotropy seems to be a generic unavoidable feature, cosmological singularities are generically avoided and it is possible to construct non-singular cosmologies where some spatial dimensions are experiencing inflation while the others experience deflation.

description: Negationen prägen Prozesse des Wissenswandels nicht nur, indem sie zu einem Aussortieren beitragen, Entwicklungen abbrechen und Platz für Neues schaffen, sondern auch durch ihnen innewohnende epistemische Potentiale. Der von Şirin Dadaş und Christian Vogel herausgegebene Band widmet sich in 17 Beiträgen diesen Dynamiken der Negation, die sich als konstitutiv für das vermittelte Wissen erweisen bzw. die Vermittlung von Wissen mitgestalten. Die Untersuchungen rücken die vielfältigen Impulse der Negation für wissensgeschichtliche Forschungen in den Blick. Es geht weniger um ein Scheitern von Transferprozessen oder um die Absenz von Wissen als um wissensgenerierende Dimensionen der Negation. Das Erkenntnisinteresse der Beiträge, die einen Untersuchungszeitraum von mehr als 2000 Jahren umfassen, richtet sich auf Wissensformen, die sich der Definition entziehen, sich nicht diskursivieren lassen oder Grenzen des Wissbaren anzeigen. Dabei wird den epistemischen Geltungsansprüchen und spezifischen Darstellungsweisen eines solchen ‚(Nicht)Wissens‘ nachgegangen. Zugleich stehen jene Negationen im Fokus, die als Ausschluss, Auflösung, Schweigen oder Zerstörung zur Wissensvermittlung dazugehören und sich derart als Ausprägungen eines ‚negativen Transfers‘ beschreiben lassen.
