description: We measured the magnetic penetration depth $λ(T)$ in single crystals of LaOs$_{4}$Sb$_{12}$ ($T_c$=0.74 K) down to 85 mK using a tunnel diode oscillator technique. The observed low-temperature exponential dependence indicates a s-wave gap. Fitting the low temperature data to BCS s-wave expression gives the zero temperature gap value $Δ(0)= (1.34 \pm 0.07) k_B T_c$ which is significantly smaller than the BCS value of 1.76$k_B T_c$. In addition, the normalized superfluid density $ρ(T)$ shows an unusually long suppression near $T_c$, and are best fit by a two-band s-wave model.

description: We report the first concurrent determination of conductance (G) and thermopower (S) of single-molecule junctions via direct measurement of electrical and thermoelectric currents using a scanning tunneling microscope-based break-junction technique. We explore several amine-Au and pyridine-Au linked molecules that are predicted to conduct through either the highest occupied molecular orbital (HOMO) or the lowest unoccupied molecular orbital (LUMO), respectively. We find that the Seebeck coefficient is negative for pyridine-Au linked LUMO-conducting junctions and positive for amine-Au linked HOMO-conducting junctions. Within the accessible temperature gradients (<30 K), we do not observe a strong dependence of the junction Seebeck coefficient on temperature. From histograms of 1000's of junctions, we use the most probable Seebeck coefficient to determine a power factor, GS^2, for each junction studied, and find that GS^2 increases with G. Finally, we find that conductance and Seebeck coefficient values are in good quantitative agreement with our self-energy corrected density functional theory calculations.

description: We propose an experimental scheme to probe the contribution of a single Dirac cone to the Hall conductivity as half-odd topological number sequence. In our scheme, the quantum anomalous Hall effect as in graphene is simulated with cold atoms trapped in an optical lattice and subjected to a laser-induced non-Abelian gauge field. By tuning the laser intensity to change the gauge flux, the energies of the four Dirac points in the first Brillouin zone are shifted with each other and the contribution of the single Dirac cone to the total atomic Hall conductivity is manifested. We also show such manifestation can be experimentally probed with atomic density profile measurements.

Scientific research regime 2.0? Transformations of the research regime and the protection of the data subject that the proposed EHDS regulation promises to bring along
Creators: name: Slokenberga, Santa
Publisher: name: Technology and Regulation
Year: 2022

description: The proposed European Health Data Space regulation (the proposed EHDS regulation) intends to facilitate the secondary use of electronic health data for scientific research purposes. The mechanism that the proposal contains will co-exist with the scientific research regime that has been established under the General Data Protection Regulation. This article examines how the proposed EHDS regulation promises to transform the EU scientific research regime and protection of a data subject in scientific research. This paper shows that a scientific research regime 2.0 is put forward, where sharing is enhanced at the cost of self-determination of the individual and without resolving many of the challenges that emerged under the GDPR.

description: In the recent years the importance of secondary uses of health data for clinical, research and policy making purposes has been further stressed in view of the availability of health-related data collected in traditional and non-traditional settings. However, processing health data - which are sensitive type of personal data - requires adopting adequate legal and ethical protections, to ensure that rights of the data subjects have been respected, while also facilitating responsible access to data. In this paper we aim to shed light on the interplay between the existing and emerging relevant European regulatory frameworks related to data processing, including the General Data Protection Regulation (GDPR), the upcoming Data Governance Act and the legislative proposal for European Health Data Space. In doing that, we will focus mainly on the legal bases for secondary uses of data in view of the overarching princi- ples of data protection.

description: It is a well known open problem if, in ZFC, each compact space with a small diagonal is metrizable. We explore properties of compact spaces with a small diagonal using elementary chains of submodels. We prove that ccc subspaces of such spaces have countable π-weight. We generalize a result of Gruenhage about spaces which are metrizably fibered. Finally we discover that if there is a Luzin set of reals, then every compact space with a small diagonal will have many points of countable character.

description: Advanced Monte Carlo simulations are used to study the effect of nano-slit confinement on metric and topological properties of model DNA chains. We consider both linear and circularised chains with contour lengths in the 1.2--4.8 $μ$m range and slits widths spanning continuously the 50--1250nm range. The metric scaling predicted by de Gennes' blob model is shown to hold for both linear and circularised DNA up to the strongest levels of confinement. More notably, the topological properties of the circularised DNA molecules have two major differences compared to three-dimensional confinement. First, the overall knotting probability is non-monotonic for increasing confinement and can be largely enhanced or suppressed compared to the bulk case by simply varying the slit width. Secondly, the knot population consists of knots that are far simpler than for three-dimensional confinement. The results suggest that nano-slits could be used in nano-fluidic setups to produce DNA rings having simple topologies (including the unknot) or to separate heterogeneous ensembles of DNA rings by knot type.

Further, we study the issue of topological defect formation in these supersymmetric theories.

description: Quantum computers, besides offering substantial computational speedups, are also expected to provide the possibility of preserving the privacy of a computation. Here we show the first such experimental demonstration of blind quantum computation where the input, computation, and output all remain unknown to the computer. We exploit the conceptual framework of measurement-based quantum computation that enables a client to delegate a computation to a quantum server. We demonstrate various blind delegated computations, including one- and two-qubit gates and the Deutsch and Grover algorithms. Remarkably, the client only needs to be able to prepare and transmit individual photonic qubits. Our demonstration is crucial for future unconditionally secure quantum cloud computing and might become a key ingredient for real-life applications, especially when considering the challenges of making powerful quantum computers widely available.

description: A ballean is a set endowed with some family of its subsets which are called the balls. We postulate the properties of the family of balls in such a way that the balleans can be considered as the asymptotic counterparts of the uniform topological spaces. The isomorphisms in the category of balleans are called asymorphisms. Every metric space can be considered as a ballean. The ultrametric spaces are prototypes for the cellular balleans. We prove some general theorem about decomposition of a homogeneous cellular ballean in a direct product of a pointed family of sets. Applying this theorem we show that the balleans of two uncountable groups of the same regular cardinality are asymorphic.

description: The paper deals with the asymptotic behavior of solutions to a non-local diffusion equation, $u_t=J*u-u:=Lu$, in an exterior domain, $Ω$, which excludes one or several holes, and with zero Dirichlet data on $\mathbb{R}^N\setminusΩ$. When the space dimension is three or more this behavior is given by a multiple of the fundamental solution of the heat equation away from the holes. On the other hand, if the solution is scaled according to its decay factor, close to the holes it behaves like a function that is $L$-harmonic, $Lu=0$, in the exterior domain and vanishes in its complement. The height of such a function at infinity is determined through a matching procedure with the multiple of the fundamental solution of the heat equation representing the outer behavior. The inner and the outer behavior can be presented in a unified way through a suitable global approximation.
On the Transient Behavior of CHOKe

Subjects: subject: Networking and Internet Architecture (cs.NI)

description: CHOKe is a simple and stateless active queue management (AQM) scheme. Apart from low operational overhead, a highly attractive property of CHOKe is that it can protect responsive TCP flows from unresponsive UDP flows. Particularly, previous works have proven that CHOKe is able to bound both bandwidth share and buffer share of (a possible aggregate) UDP traffic (flow) on a link. However, these studies consider, and pertain only to, a steady state where the queue reaches equilibrium in the presence of many (long-lived) TCP flows and an unresponsive UDP flow of fixed arrival rate. If the steady state conditions are perturbed, particularly when UDP traffic rate changes over time, it is unclear whether the protection property of CHOKe still holds. Indeed, it can be examined, for example, that when UDP rate suddenly becomes 0 (i.e., flow stops), the unresponsive flow may assume close to full utilization in sub-RTT scales, potentially starving out the TCP flows. To explain this apparent discrepancy, this paper investigates CHOKe queue properties in a transient regime, which is the time period of transition between two steady states of the queue, initiated when the rate of the unresponsive flow changes. Explicit expressions that characterize flow throughputs in transient regimes are derived. These results provide additional understanding of CHOKe, and give some explanation on its intriguing behavior in the transient regime.

Absolute stability of axisymmetric perturbations in strongly-magnetized collisionless axisymmetric accretion disk plasmas

description: The physical mechanism responsible for driving accretion flows in astrophysical accretion disks is commonly thought to be related to the development of plasma instabilities and turbulence. A key question is therefore the determination of consistent equilibrium configurations for accretion-disk plasmas and investigation of their stability properties. In the case of collisionless plasmas kinetic theory provides the appropriate theoretical framework. This paper presents a kinetic description of low-frequency and long-wavelength axisymmetric electromagnetic perturbations in non-relativistic, strongly-magnetized and gravitationally-bound axisymmetric accretion-disk plasmas in the collisionless regime. The analysis, carried out within the framework of the Vlasov-Maxwell description, relies on stationary kinetic solutions of the Vlasov equation which allow for the simultaneous treatment of non-uniform fluid fields, stationary accretion flows and temperature anisotropies. It is demonstrated that, for such solutions, no axisymmetric unstable perturbations can exist occurring on characteristic time and space scales which are long compared with the Larmor gyration time and radius. Hence, these stationary configurations are actually stable against axisymmetric kinetic instabilities of this type. As a fundamental consequence, this rules out the possibility of having the axisymmetric magneto-rotational or thermal instabilities to arise in these systems.

description: The Josephson coupling between optimally cuprate superconductors separated by a spacer with a finite energy cooperon excitation which contributes to the Josephson coupling strength, is examined. For an underdoped cuprate barrier in its normal state, the YRZ model gives a good description of the temperature dependent enhanced Josephson coupling. A detailed examination of origin of the enhancement shows a significant contribution from the cooperon excitation which is comparable to that from nodal quasiparticles.

A generalised porosity formalism for isotropic and anisotropic effective opacity and its effects on X-ray line attenuation in clumped O star winds

description: We present a generalised formalism for treating the porosity-associated reduction in continuum opacity that occurs when individual clumps in a stochastic medium become optically thick. We consider geometries resulting in either isotropic or anisotropic effective opacity, and, in addition to an idealised model in which all clumps have the same local overdensity and scale, we also treat an ensemble of clumps with optical depths set by Markovian statistics. This formalism is then applied to the specific case of bound-free absorption of X-rays in hot star winds, a process not directly affected by clumping in the optically thin limit. We find that the Markov model gives surprisingly similar results to those found previously for the single clump model, suggesting that porous opacity is not very sensitive to details of the assumed clump distribution function. Further, an anisotropic effective opacity favours escape of X-rays emitted in the tangential direction (the `venetian blind' effect), resulting in a 'bump' of higher flux close to line centre as compared to profiles computed from isotropic porosity models. We demonstrate how this characteristic line shape may be used to diagnose the clump geometry, and we confirm previous results that for optically thick clumping to significantly influence X-ray line profiles, very large porosity lengths, defined as the mean free path between clumps, are required. Moreover, we present the first X-ray line profiles computed directly from line-driven instability simulations using a 3-D patch method, and find that porosity effects from such models also are very small. This further supports the view that porosity has, at most, a marginal effect on X-ray line diagnostics in O stars, and therefore that these diagnostics do indeed provide a good `clumping insensitive' method for deriving O star mass-loss rates.

Dream in Persian medicine perspective: A narrative review

description: Sleep and dream are the inseparable parts of the human life, so their disturbance can affect the individuals’ quality of life. Sages of Persian medicine (PM) had valued dream as a part of history taking and physical examination for diagnosis of the diseases. Recently, psychologists and psychotherapists have focused on several aspects of dream. The aim of this review study was to explain the overviews of the sages of PM about dream and its aspects. The main sources of PM including The Canon of Medicine, Kholase Al-Hekmat, Firdous al-Hikmah, Mofareh Al-Gholub, Sharhe aghsaraei and also the NOOR software was reviewed by these keywords: “khab”, “roya”, “navm”, and “azqâth-e-ahlâm”. In addition, electronic data bases including PubMed Central, MEDLINE, Scopus, and Google Scholar were searched. Finally, the gathered information was presented. According to PM, the potential functionality of dream contents can be exploited to shed light on the temperamental diagnosis, and there are modalities whereby dream interpretation can be useful in diagnosis. PM considers the clues from one’s sleep/wakefulness ratio to discern one’s temperament: where abundance of wakeful hours indicates hotness and/or dryness of temperament, too much sleep signals an indication of coldness and/or wetness of temperament. Such discerning of temperaments itself acts as a suitable prelude to proper diagnosis. In conclusion, PM sages had recommended that the individuals’ dreams depend on their temperament. In this regard, it is suggested that experimental and clinical studies on dream should be designed with integration of conventional medicine and PM.

description: These notes provide a concise introduction to important applications of the renormalization group (RG) in statistical physics. After reviewing the scaling approach and Ginzburg-Landau theory for critical phenomena, Wilson's momentum shell RG method is presented, and the critical exponents for the scalar Phi^4 model are determined to first order in an eps expansion about d_c = 4. Subsequently, the technically more versatile field-theoretic formulation of the perturbational RG for static critical phenomena is described. It is explained how the emergence of scale invariance connects UV divergences to IR singularities, and the RG equation is employed to compute the critical exponents for the O(n)-symmetric Landau-Ginzburg-Wilson theory. The second part is devoted to field theory representations of non-linear stochastic dynamical systems, and the application of RG tools to critical dynamics. Dynamic critical phenomena in systems near equilibrium are efficiently captured through Langevin equations, and their mapping onto the Janssen-De Dominicis response functional, exemplified by the purely relaxational models with non-conserved (model A) / conserved order parameter (model B). The Langevin description and scaling exponents for isotropic ferromagnets (model J) and for driven diffusive non-equilibrium systems are also discussed. Finally, an outlook is presented to scale-invariant phenomena and non-equilibrium phase transitions in interacting particle systems. It is shown how the stochastic master equation associated with chemical reactions or population dynamics models can be mapped onto imaginary-time, non-Hermitian `quantum' mechanics. In the continuum limit, this Doi-Peliti Hamiltonian is represented through a coherent-state path integral, which allows an RG analysis of diffusion-limited annihilation processes and phase transitions from active to inactive, absorbing states.

description: HR 8799 is currently the only multiple-planet system that has been detected with direct imaging, with four giant planets orbiting at large separations from this young late A star. Orbital motion provides insight into the stability, and possible formation mechanisms of this planetary system. Dynamical studies can also provide constraints on the planets' masses, which help calibrate evolutionary models. Yet, measuring the orbital motion is a very difficult task because the long-period orbits (50-500 yr) require long time baselines and high-precision astrometry. This paper studies the three planets HR 8799b, c and d in the archival data set of HR 8799 obtained with the HST NICMOS coronagraph in 1998. The detection of all three planets is made possible by a careful optimization of the LOCI algorithm. This work confirms previous astrometry for planet b, and presents new detections and astrometry for c and d. These HST images provide a ten-year baseline with the discovery images from 2008, and therefore offer a unique opportunity to constrain their orbital motion now. Recent dynamical studies of this system show the existence of a few possible stable solutions involving mean motion resonances, where the interaction between c and d plays a major role. We study the compatibility of a few of these stable scenarios (1d:1c, 1d:2c, or 1d:2c:4d) with the new astrometric data from HST. In the hypothesis of a 1d:2c:4b mean motion resonance our best orbit fit is close to the stable solution previously identified for a three-planet system, and involves low eccentricity for planet d (ed = 0.10) and moderate inclination of the system (i = 28.0 deg), assuming a coplanar system, circular orbits for b and c, and exact resonance with integer period ratios. Under these assumptions, we can place strong constraints on the inclination of the system (27.3 - 31.4 deg) and on the eccentricity for d ed < 0.46.

description: An experimental setup for determining the electrical resistivity of several types of thermoelectric materials over the temperature range 20 < T < 550 C is described in detail. One resistivity measurement during temperature cycling is also explained for Cu0.01Bi2Te2.7Se0.3 while a second measurement is made on Yb0.35Co4Sb12 as a function of time at 400 C. Both measurements confirm that the materials are thermally stable for the temperature range and time period measured. Measurements made during temperature cycling show an irreversible decrease in the electrical resistivity of Cu0.01Bi2Te2.7Se0.3 when the measuring temperature exceeds the pressing temperature. Several other possible uses of such a system include but are not limited to studying the effects of annealing and/or oxidation as a function of both temperature and time.
PERCEIVED EFFECT OF ONLINE GAMES ON THE CRITICAL THINKING SKILLS OF GRADE 9 AND 10 HIGH SCHOOL STUDENTS OF ST. JOHN'S INSTITUTE, INC.

description: This study is grounded in the Theory of Game-Based Learning (GBL) and aims to investigate the perceived effects of online games on the critical thinking skills of Grade 9 and 10 students. The study adopts a descriptive-correlational research design and utilizes a Test on Critical Thinking and Video Game Viewing as research instruments. Data was collected from the students of St. John's Institute, Inc., Infanta, Pangasinan, during the academic year 2022-2023. The findings indicate that, when taken as an entire group, the extent of perceived effect of online gaming was described as "Less Proficient," while the critical thinking skills were described as "Highly Accomplished." When classified by grade level, Grade 9 students exhibited a "Developing" level in the perceived effect of online games and a "Highly Accomplished" level in critical thinking skills. Grade 10 students, on the other hand, showed a "Less Proficient" level in the perceived effect of online games and a "Highly Accomplished" level in critical thinking skills. Furthermore, there is a significant difference in the perceived effects of online games on critical thinking skills when classified by grade level. The study concludes that there is a significant relationship between online gaming and critical thinking skills, although previous research has produced mixed results. Recommendations for further research include conducting similar studies with different student populations, extending the duration of the study, using other online games with appropriate evaluation rubrics, increasing awareness among teachers and parents about the potential benefits of online games in developing critical thinking skills, integrating online games as a teaching strategy, and considering the integration of online games into the curriculum.

In comparison with the cosmological constant via information criteria, it is found that models with potentials $\exp(M_{p}/ϕ)$, $\exp(M_{p}/ϕ)-1$ and $\exp(γM_{p}/ϕ)-1$ are not supported by the current data.

description: We present a three-dimensional model of rotating convection combined with a simplified corona in spherical coordinates. The motions in the convection zone generate a large-scale magnetic field that gets sporadically ejected into the outer layers above. Our model corona is approximately isothermal, but it includes density stratification due to gravity.

description: We investigate the levels of small scale structure in surface brightness images of the core of the X-ray bright cool-core galaxy cluster AWM 7. After subtraction of a model of the smooth cluster emission, we find a number of approximately radial surface brightness depressions which are not present in simulated images and are seen in both the Chandra and XMM-Newton data. The depressions are most strongly seen in the south of the cluster and have a magnitude of around 4 per cent in surface brightness. We see these features in both an energy band sensitive to the density (0.6 to 5 keV) and a band more sensitive to the pressure (3.5 to 7.5 keV). Histograms of surface brightness in the data, when compared to realisations of a smooth model, reveal stronger surface brightness variations. We use the Delta-variance technique to characterise the magnitude of the fluctuations as a function of length scale. We find that the spectrum in the 0.6 to 5 keV band is flatter than expected for Kolmogorov index fluctuations. If characterised by a power spectrum, on large scales it would have an index around -1.7, rather than -3.7. The implied 3D density fluctuations have a standard deviation of around 4 per cent. The implied 3D pressure variations are at most 4 per cent. Most of the longer-scale power in the density spectrum is contributed by the southern half of the cluster, where the depressions are seen. The density variations implied by the spectrum of the northern sector have a standard deviation of about 2 per cent.

description: Η παρούσα διπλωματική εργασία επικεντρώνεται στο να διερευνήσει, με βάση τη σημειωτική θεωρία, τα διαφημιστικά μηνύματα του εγχειριδίου της Νεοελληνικής Γλώσσας Ε΄ Δημοτικού, τη σχέση μεταξύ τους και τη χρησιμότητά τους στη μαθησιακή διαδικασία. Συγκεκριμένα, τα διαφημιστικά μηνύματα του σχολικού εγχειριδίου εξετάζονται μέσα από έναν συνδυασμό θεωρητικών και μεθοδολογικών προσεγγίσεων για τη σχέση γλώσσας και εικόνας που αναπτύχθηκαν στον χώρο της εφαρμοσμένης σημειωτικής. Η έρευνα αυτή στοχεύει να παρέχει μία βαθύτερη κατανόηση του τρόπου με τον οποίο τα διαφημιστικά μηνύματα μπορούν να ενισχύσουν τη διδασκαλία της γλώσσας και να συμβάλλουν στη συνολική εκπαιδευτική διαδικασία, βελτιώνοντας την εκπαιδευτική εμπειρία των μαθητών/τριών. Τα συμπεράσματα της έρευνάς αποκαλύπτουν τη σημασία της σημειωτικής προσέγγισης στην ανάλυση των διαφημιστικών μηνυμάτων, καθώς και τον τρόπο με τον οποίο οι γλωσσικοί και εικονικοί κώδικες συνδυάζονται για να μεταδοθεί αποτελεσματικά το πληροφοριακό φορτίο. Επιπλέον, υπογραμμίζεται ο ουσιώδης ρόλος αυτών των μηνυμάτων στην ανάπτυξη του οπτικού γραμματισμού και του γραμματισμού γενικότερα. Ωστόσο προτείνεται η ανανέωση του διαφημιστικού υλικού του σχολικού εγχειριδίου ώστε να ανταποκριθεί στις σύγχρονες τεχνολογικές προκλήσεις και να αξιοποιήσει τις δυνατότητες της πολυτροπικότητας στην εκπαίδευση, καθιστώντας την πιο αποτελεσματική και ελκυστική για τους/τις μαθητές/τριες.
description: This thesis focuses on investigating, based on semiotic theory, the advertising messages in the textbook of Modern Greek Language for year 5, their relationship, and their usefulness in the learning process. Specifically, the advertising messages in the school textbook are examined through a combination of theoretical and methodological approaches regarding the relationship between language and image, developed in the field of applied semiotics. This research aims to provide a deeper understanding of how advertising messages can enhance language teaching and contribute to the overall educational process, improving the educational experience of pupils. The research findings reveal the importance of the semiotic approach in analysing advertising messages and how linguistic and visual codes combine to effectively convey informational content. Additionally, the essential role of these messages in developing visual literacy and literacy, in general, is highlighted. However, it is suggested that the advertising material in the school textbook should be updated so as to meet contemporary technological challenges and to utilize the potential of multimodality in education, making it more effective and engaging for pupils.

description: The one of the metaheuristic approaches that can be used was simulated annealing (SA) algorithm which inspired by annealing metallurgical process. This algorithm shows advantages in finding global optimum of given function which will be used in feature selection. In this study, we will trying to combine the neighborhood size and limited approach by using data simulation comparing between two function which is Akaike Index Criterion (AIC) function and Bayesian Index Criterion (BIC) function. The result of this experiment shows that the selected variables using optimal neighborhood size and limit the selected variable provide the result of goodness model around 98% of accuracy and specificity and 94% of sensitivity compared with simulated annealing algorithms without any modification using both AIC function and BIC function, and in the simulation also shows that BIC function give better result than AIC function.

Non-adiabatic optomechanical Hamiltonian of a moving dielectric membrane in a cavity
Creators: name: Cheung, H. K.

Publisher: name: arXiv
Year: 2011
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: We formulate a non-relativistic Hamiltonian in order to describe the interaction between a moving dielectric membrane and radiation pressure. Such a Hamiltonian is derived without making use of the single-mode adiabatic approximation, and hence it enables us to incorporate multi-mode effects in cavity optomechanics. By performing second quantization, we show how a set of generalized Fock states can be constructed to represent quantum states of the membrane and cavity field. In addition, we discuss examples showing how photon scattering among different cavity modes would modify the interaction strengths and the mechanical frequency of the membrane.
