description: A circular ribbon flare SOL2014-12-17T04:51 is studied using the 17/34 GHz maps from the Nobeyama Radioheliograph (NoRH) along with (E)UV and magnetic data from the Solar Dynamics Observatory (SDO). We report the following three findings as important features of the microwave CRF. (1) The first preflare activation comes in the form of a gradual increase of the 17 GHz flux without a counterpart at 34 GHz, which indicates thermal preheating. The first sign of nonthermal activity occurs in the form of stepwise flux increases at both 17 and 34 GHz about 4 min before the impulsive phase. (2) Until the impulsive phase, the microwave emission over the entire active region is in a single polarization state matching the magnetic polarity of the surrounding fields. During and after the impulsive phase, the sign of the 17 GHz polarization state reverses in the core region, which implies a magnetic breakout--type eruption in a fan-spine magnetic structure. (3) The 17 GHz flux around the time of the eruption shows quasi-periodic variations with periods of 1--2 min. The pre-eruption oscillation is more obvious in total intensity at one end of the flare loop, and the post-eruption oscillation, more obvious in the polarized intensity at a region near the inner spine. We interpret this transition as the transfer of oscillatory power from kink mode oscillation to torsional Alfvén waves propagating along the spine field after the eruption. We argue that these three processes are inter-related and indicate a breakout process in a fan-spine structure.

description: Satellite remote sensing has been widely used in the last decades for agricultural applications, {both for assessing vegetation condition and for subsequent yield prediction.} Existing remote sensing-based methods to estimate gross primary productivity (GPP), which is an important variable to indicate crop photosynthetic function and stress, typically rely on empirical or semi-empirical approaches, which tend to over-simplify photosynthetic mechanisms. In this work, we take advantage of all parallel developments in mechanistic photosynthesis modeling and satellite data availability for advanced monitoring of crop productivity. In particular, we combine process-based modeling with the soil-canopy energy balance radiative transfer model (SCOPE) with Sentinel-2 {and Landsat 8} optical remote sensing data and machine learning methods in order to estimate crop GPP. Our model successfully estimates GPP across a variety of C3 crop types and environmental conditions even though it does not use any local information from the corresponding sites. This highlights its potential to map crop productivity from new satellite sensors at a global scale with the help of current Earth observation cloud computing platforms.

description: This paper describes an original experimental procedure to measure the mechanical interaction between the tongue and teeth and palate during speech production. It consists in using edentulous people as subjects and to insert pressure sensors in the structure of their complete dental prosthesis. Hence, there is no perturbation of the vocal tract cavity due to the sensors themselves. Several duplicates are used with transducers situated at different locations of the complete denture according to palatography's results, in order to carefully analyze the production of specific sounds such as stop consonants.. It is also possible to measure the contact pressure at different locations on the palate for the same sound.

description: The TRACER instrument (``Transition Radiation Array for Cosmic Energetic Radiation'') has been developed for direct measurements of the heavier primary cosmic-ray nuclei at high energies. The instrument had a successful long-duration balloon flight in Antarctica in 2003. The detector system and measurement process are described, details of the data analysis are discussed, and the individual energy spectra of the elements O, Ne, Mg, Si, S, Ar, Ca, and Fe (nuclear charge Z=8 to 26) are presented. The large geometric factor of TRACER and the use of a transition radiation detector make it possible to determine the spectra up to energies in excess of 10$^{14}$ eV per particle. A power-law fit to the individual energy spectra above 20 GeV per amu exhibits nearly the same spectral index ($\sim$ 2.65 $\pm$ 0.05) for all elements, without noticeable dependence on the elemental charge Z.

description: We consider a DGP brane scenario where a scalar field is present on the brane through the introduction of a scalar potential, itself motivated by the notion of modified gravity. This theory predicts that the mass appearing in the gravitational potential is modified by the addition of the mass of the scalar field. The cosmological implications that such a scenario entails are examined and shown to be consistent with a universe expanding with power-law acceleration.

description: Time-series VI CCD photometry of the globular cluster M10 (NGC 6254) is employed to perform a detailed identification, inspection of their light curves, their classification and their cluster membership, of all the known variables reported up to 2018. The membership analysis is based on the Gaia-DR2 positions and proper motions. The metallicity of the cluster is estimated based on the sole RRc star known in the cluster. The Fourier decomposition of its light curve leads to [Fe/H]ZW=-1:59 $\pm$ 0:23 dex. The mean cluster distance, estimated by several independent methods is 5.0 $\pm$ 0.3 kpc. A multi-approach search in a region of about 10x10 arcmin2 around the cluster revealed three new variables, one SX Phe (V35) and two sinusoidal variables on the red giant branch of unclear classification (V36,V37). Modelling the HB stars is very sensitive to the stellar hydrogen shell mass, which surrounds the 0.50 M$_\odot$ helium core. To match the full stretch of the HB population, a range of total mass of 0.56 to 0.62 M$_\odot$ is required. These models support a distance of 5.35 kpc and an age of about 13 Gyrs, and hints to some individual variation of the mass loss on the uppper RGB, perhaps caused by the presence of closed magnetic field in red giants.

description: We analyze the properties of Neel and Bloch domain walls as a function of film thickness h, for systems where, in addition to exchange, the dipole-dipole interaction must be included. The Neel to Bloch phase transition is found to be a second order transition at hc, mediated by a single unstable mode that corresponds to oscillatory motion of the domain wall center. A uniform out-of-plane rf-field couples strongly to this critical mode only in the Neel phase. An analytical Landau theory shows that the critical mode frequency varies as the square root of (hc - h) just below the transition, as found numerically.

Η απελευθέρωσή της το 961 από το Νικηφόρο Φωκά αποτελεί το σημαντικότερο γεγονός της βασιλείας του Ρωμανού Β', καθώς ελευθέρωνε οριστικά τις ελληνικές θάλασσες από τη μάστιγα των Σαρακηνών, εξασφάλιζε στο βυζαντινό κράτος μια ζωτικότατη εξαιτίας της γεωγραφικής της θέσης εμπορική και πολεμική βάση και απέδιδε στο έθνος την πολυπαθή μεγαλόνησο
description: Crete was under arab occupation for more that 100 years. This was a huge wound for the byzantine empire because the arabs, having Crete as a hide-out, they were harassing the byzantine traade and the population of the eastern mediterannean sea and the Aegean Sea. The liberation of the island in 961 by Nicephorus Phocas is the most important fact of the reign of Romanos II and one of the biggest success of the byzantine empire against the arabs, during the second half of 10th century because it was liberating permanently the greek seas from the saracens, it was obtaining to the byzantine state a very vital commercial and polemical base and it was atributing to the nation the sorely tried island

description: We experimentally demonstrate fabrication of tunable high contrast periodic fishnet metasurfaces with 3 um period on 200 nm thick Ge2Sb2Te5 films sputted onto glass and sapphire substrates using direct laser writing technique. We find that the use of sapphire substrate provides better accuracy of metasurface segments due to high thermal conductivity. The advantages of the demonstrated method consist in its simplicity, rapidity, robustness, and the ability of tuning of fabricated structures. This is of crucial importance for the creation of robust and tunable metasurfaces for applications in the field of telecommunications and information processing.

Negative reflections of electromagnetic waves in chiral media

description: We investigate the reflection properties of electromagnetic/optical waves in isotropic chiral media. When the chiral parameter is strong enough, we show that an unusual \emph{negative reflection} occurs at the interface of the chiral medium and a perfectly conducting plane, where the incident wave and one of reflected eigenwaves lie in the same side of the boundary normal. Using such a property, we further demonstrate that such a conducting plane can be used for focusing in the strong chiral medium. The related equations under paraxial optics approximation are deduced. In a special case of chiral medium, the chiral nihility, one of the bi-reflections disappears and only single reflected eigenwave exists, which goes exactly opposite to the incident wave. Hence the incident and reflected electric fields will cancel each other to yield a zero total electric field. In another word, any electromagnetic waves entering the chiral nihility with perfectly conducting plane will disappear.

In this study, I show that if cosmic strings are produced after symmetry breaking at the end of hilltop supernatural inflation, this small-field inflation model can be tested through the production of gravitational waves from cosmic strings. Future experiments of gravitational wave detectors will determine or further constrain the parameter space in the model.

description: We present a study of a peculiar nebula MF16 associated with an Ultraluminous X-ray Source NGC6946 ULX-1. We use integral-field and long-slit spectral data obtained with the 6-m telescope (Russia). The nebula was for a long time considered powered by strong shocks enhancing both high-excitation and low-excitation lines. However, kinematical properties point to rather moderate expansion rates (V ~ 100-200 km/s). The total power of the emission-line source exceeds by one or two orders of magnitude the power observed expansion rate can provide, that points towards the existence of an additional source of excitation and ionization. Using CLOUDY96.01 photoionization code we derive the properties of the photoionizing source. Its total UV/EUV luminosity must be about 10^{40} erg/s.

description: The pulp and paper industry has historically been one of the world’s largest consumers of freshwater resources and producers of wastewater discharges. These discharges have been the continuing focus of concern regarding their actual and potential environmental effects. More than 250 chemicals have been identified in effluents that are produced at different stages of papermaking. The most significant environmental issues are the discharge of chlorine-based organic compounds and of other toxic organics. Several organic compounds are resistant to biological degradation, especially color related compounds and compounds causing a high cationic demand. Depending on the quality of the paper that is produced, additional physical–chemical treatment may therefore be required. The goal of this study was to analyze the real wastewater from the paper mill and to suggest a method of additional treatment in order to reduce organic pollutants load, which is typically high for the industry. Photocatalysis was suggested as the method of additional treatment. The purpose of photocatalytic experiments was to investigate the efficiency of two most common for wastewater treatment photocatalytic processes – photo-TiO2 and photo-Fenton – for treatment of the real paper mill effluent and to compare the efficiency of the two processes and also the efficiency of TiO2 photocatalytic reactions with and without addition oh H2O2, and finally to investigate at which stage of treatment process photocatalysis can be employed. The investigated paper mill produces 3 grades of paper – toilet paper, kitchen paper and tissue. The mill uses long fibber, short fibber or chemic-thermo-mechanical pulps, which the mill does not produce itself. For the experiment a 500 mL pyrex UV reactor and a 125 W high-pressure mercury lamp, surrounded by pyrex filter blocking wavelengths below 290 nm, were used.

description: We perform a Monte-Carlo study of the lattice two-dimensional gauged XY-model. Our results confirm the strong-coupling expansion arguments that for sufficiently small values of the spin-spin coupling the ``gauge symmetry breaking" terms decouple and the long-distance physics is that of the unbroken pure gauge theory. We find no evidence for the existence, conjectured earlier, of massless states near a critical value of the spin-spin coupling. We comment on recent remarks in the literature on the use of gauged XY-models in proposed constructions of chiral lattice gauge theories.

description: Using the CGC effective theory together with the hybrid factorisation, we study forward dijet production in proton-nucleus collisions beyond leading order. In this paper, we compute the "real" next-to-leading order (NLO) corrections, i.e. the radiative corrections associated with a three-parton final state, out of which only two are being measured. To that aim, we start by revisiting our previous results for the three-parton cross-section presented in our previous paper. After some reshuffling of terms, we deduce new expressions for these results, which not only look considerably simpler, but are also physically more transparent. We also correct several errors in this process. The real NLO corrections to inclusive dijet production are then obtained by integrating out the kinematics of any of the three final partons. We explicitly work out the interesting limits where the unmeasured parton is either a soft gluon, or the product of a collinear splitting. We find the expected results in both limits: the B-JIMWLK evolution of the leading-order dijet cross-section in the first case (soft gluon) and, respectively, the DGLAP evolution of the initial and final states in the second case (collinear splitting). The "virtual" NLO corrections to dijet production will be presented in a subsequent publication.

description: Superconducting circuit quantum electrodynamics (QED) architecture composed of superconducting qubit and resonator is a powerful platform for exploring quantum physics and quantum information processing. By employing techniques developed for superconducting quantum computing, we experimentally investigate phase-sensitive Landau-Zener-Stückelberg (LZS) interference phenomena in a circuit QED. Our experiments cover a large range of LZS transition parameters, and demonstrate the LZS induced Rabi-like oscillation as well as phase-dependent steady-state population.

description: SS433 is the only known persistent supercritical accretor, it may be very important for understanding ultraluminous X-ray sources (ULXs) located in external galaxies. We describe main properties of the SS433 supercritical accretion disk and jets. Basing on observational data of SS433 and published 2D simulations of supercritical accretion disks we estimate parameters of the funnel in the disk/wind of SS 433. We argue that the UV radiation of the SS433 disk (~50000 K, ~10^{40}erg/s) is roughly isotropic, but X-ray radiation (~10^7 K, ~10^{40}erg/s) of the funnel is midly anisotropic. A face-on SS433 object has to be ultraluminous in X-rays (10^{40-41}erg/s). Typical time-scales of the funnel flux variability are estimated. Shallow and very broad (0.1-0.3c) and blue-shifted absorption lines are expected in the funnel X-ray spectrum.

title: Simulation to Augment Standardized Patients in Obstetric Ultrasound Training
Creators: name: Guirlinger, Scott Richard
Publisher: name: Old Dominion University Libraries
Year: 2007

description:
Standardized patients are actors used in medical training to teach and eval11atc clinical skills of students prior to their using these skills on an actual patient. Augmented Reality is a relatively new technology that can be used to augment standardized patients with abnonnalitie8 and pathologies that they cannot portray themselves as normal healthy human beings. In our project, we sought to augment standardized patients with a 12-week- old fetus in order to train and possibly evaluate medical students and professionals in performing obstetric ultrasound procedures and interpreting the corresponding ultrasound image results.

The software library ARToolkit provided the framework for our computer application, utilizing a visual tracking system that consisted of merely a single webcam and several black and white pattern targets. OpenGL functions were used to render three-dimensional virtual objects and apply two-dimensional textures. More complex anatomical shapes were created and modified using 3ds Max software and then imported into om program during execution. Our final application featured one view displaying the video frames with superimposed vi1tual objects, another view exposing all of the virtual objects in three-dimensional space, and a final view showing two-dimensional ultrasound output.

description: This thesis treats the representation of the personifications of Earth (Gaia) and Tyche in mosaic pavements and textiles of late antiquity and consists of 5 chapters. After the introduction, where the targets are set follows an analytic catalogue of 53 lemmas. In the third and fourth chapter are studied separately and extensively the two personifications. Are analysed in subchapters the figure and their symbols, the figures when sometimes accompany them, the scenes in which take place and the decorative context of their illustrations. The study ends with the conclusions where become clear the reasons that we examine together the two personifications and the two types of art. The thesis"companies" the bibliography, the illustration catalogue and the illustrations. In the study is collected a representative published material in which are added some unpublished textiles from Benaki Museum and British Museum. Issues of interpretation and chronology are set, new recognitions are proposed and an effort is made in order to give a complete picture of Gaia and Tyche in textiles and mosaic pavements of late antiquity.

description: The present paper concerns about equivalence relations and moreover about equivalence of polynomial matrices as well as system equivalence. The paper is divided into two sections. More precisely, the first section deals with the structure of polynomial matrices, the elementary transformation of those as well as the geometric interpretation of invariants that these transformations keep in relation to the solutions of the linear differential equations of the matrices. There is an extensive analysis of the unimodular equivalence which is about polynomial matrices of the same dimension and of the extended unimodular equivalence that is about polynomial matrices of different dimensions. The second section is about system equivalence and specifically state-space systems equivalence, Rosenbrock’s strict system equivalence, unimodular equivalence systems and Fuhrmann’s system equivalence. KEY WORDS Equivalence, Smith form, polynomial matrix, unimodular equivalence, extended unimodular equivalence, system equivalence, state-space equivalence, Rosenbrock’s equivalence, Fuhrmann’s equivalence.
Localization POVMs and intrinsic temporal uncertainty

description: The causality issues concerning the localization of relativistic quantum systems, as evidenced by Hegerfeld's paradox, are addressed through a proper-time formalism of single-particle operators. Starting from the premise that physical variables associated to the proper-time gauge have a prominent role in the specification of position, since they do not depend on classical parameters connected to an external observer, we obtain a single-particle formalism in which localization is described by explicitly covariant four-vector operators associated with POVM measurements parametrized by the system's proper-time. Among the consequences of this result, we emphasize that physically acceptable states are necessarily associated with the existence of a temporal uncertainty and their proper-time evolution is not subject to the causality violation predicted by Hegerfeldt.

description: A gas of strongly interacting spinless p-orbital fermionic atoms in 2D optical lattices is proposed and studied. Several interesting new features are found. In the Mott limit on a square lattice, the gas is found to be described effectively by an orbital exchange Hamiltonian equivalent to a pseudospin-1/2 XXZ model. For a triangular, honeycomb, or Kagome lattice, the orbital exchange is geometrically frustrated and described by a new quantum 120 degree model. We determine the orbital ordering on the Kagome lattice, and show how orbital wave fluctuations select ground states via the order by disorder mechanism for the honeycomb lattice. We discuss experimental signatures of various orbital ordering.

description: Molecular dynamics simulations provide a mechanistic description of molecules by relying on empirical potentials. The quality and transferability of such potentials can be improved leveraging data-driven models derived with machine learning approaches. Here, we present TorchMD, a framework for molecular simulations with mixed classical and machine learning potentials. All of force computations including bond, angle, dihedral, Lennard-Jones and Coulomb interactions are expressed as PyTorch arrays and operations. Moreover, TorchMD enables learning and simulating neural network potentials. We validate it using standard Amber all-atom simulations, learning an ab-initio potential, performing an end-to-end training and finally learning and simulating a coarse-grained model for protein folding. We believe that TorchMD provides a useful tool-set to support molecular simulations of machine learning potentials. Code and data are freely available at \url{github.com/torchmd}.

description: We present a study of the association between class I methanol masers and cold dust clumps from the ATLASGAL survey. It was found that almost 100% of class I methanol masers are associated with objects listed in the ATLASGAL compact source catalog. We find a statistically significant difference in the flux density, luminosity, number and column density and temperature distributions of ATLASGAL sources associated with 95/44 GHz methanol masers compared with those ATLASGAL sources devoid of 95 GHz methanol masers. The masers tend to arise in clumps with higher densities, luminosities and temperatures compared with both the full sample of the ATLASGAL clumps, as well as the sample of ATLASGAL sources that were cross-matched with positions previously searched for methanol masers but with no detections. Comparison between the peak position of ATLASGAL clumps and the interferometric positions of the associated class I and II methanol masers reveals that class I masers are generally located at larger physical distances from the peak submillimetre emission than class II masers. We conclude that the tight association between ATLASGAL sources and class I methanol masers may be used as a link toward understanding the conditions of the pumping of these masers and evolutionary stages at which they appear.

description: Based on the Gerstenhaber Theory, clarification is made of how operadic dynamics may be introduced. Operadic observables satisfy the Gerstenhaber algebra identities and their time evolution is governed by operadic evolution equation. The notion of an operadic Lax pair is also introduced. As an example, an operadic (representation of) harmonic oscillator is proposed.

description: Recently, researches attention has been focused on the development of mucosal immunity strategies based on the use of probiotic spores as mucosal adjuvant. Therefore, they represent a good adjuvant to deliver antigens into the gastrointestinal tract and they could be used to mucosal vaccine. The mucosal vaccinology was used also for down-regulating inflammatory conditions. Among these conditions, celiac disease (CD) represents a very interesting model to test possible immunomodulatory strategies. So the aim of my research has been the use of Bacillus subtilis spores as a display system to development an immunomodulatory strategies for celiac disease.
A Brain-Adaptive Dynamic Persistence Equation: Toward a Universal Model of Cognitive Integrity
Creators: name: Giannakopoulos, Bill
Publisher: name: OSF
Year: 2025

description: This component presents an adapted, brain-specific formulation of the Persistence Equation to model cognitive stability, plasticity, and collapse under thermodynamic and informational stress. Grounded in the principles of systems neuroscience and inspired by Denis Noble’s multiscale modeling, the framework captures how the brain resists entropic degradation through reversibility (η), structural buffering (α), and environmental volatility (T). It provides a foundation for dynamic modeling of neurodegeneration, memory persistence, recovery after insult, and the role of mutual information in maintaining cognitive coherence. This work is part of the broader Persistence Theory project aimed at unifying biology, computation, and thermodynamics through a single probabilistic survival framework.
