description: We inspect the evolution of SIRs from Earth to Mars (distance range 1-1.5 AU) over the declining phase of solar cycle 24 (2014-2018). So far, studies only analyzed SIRs measured at Earth and Mars at different times. We compare existing catalogs for both heliospheric distances and arrive at a clean dataset for the identical time range. This allows a well-sampled statistical analysis and for the opposition phases of the planets an in-depth analysis of SIRs as they evolve with distance. We use in-situ solar wind data from OMNI and the MAVEN spacecraft as well as remote sensing data from SDO. A superposed epoch analysis is performed for bulk speed, proton density, temperature, magnetic field magnitude and total perpendicular pressure. Additionally, a study of events during the two opposition phases of Earth and Mars in the years 2016 and 2018 is conducted. SIR related coronal holes with their area as well as their latitudinal and longitudinal extent are extracted and correlated to the maximum bulk speed and duration of the corresponding high speed solar wind streams following the stream interaction regions. We find that while the entire solar wind HSS shows no expansion as it evolves from Earth to Mars, the crest of the HSS profile broadens by about 17%, and the magnetic field and total pressure by about 45% around the stream interface. The difference between the maximum and minimum values in the normalized superposed profiles increases slightly or stagnates from 1-1.5 AU for all parameters, except for the temperature. A sharp drop at zero epoch time is observed in the superposed profiles for the magnetic field strength at both heliospheric distances. Maximum solar wind speed has a stronger dependence on the latitudinal extent of the respective coronal hole than on its longitudinal extent. We arrive at an occurrence rate of fast forward shocks three times as high at Mars than at Earth.

description: We have carried out the harmonic analysis of the atomic hydrogen (HI) surface density maps and the velocity fields for 11 galaxies belonging to the Ursa Major group, over a radial range of 4-6 disc scalelengths in each galaxy. This analysis gives the radial variation of spatial lopsidedness, quantified by the Fourier amplitude A$_1$ of the m=1 component normalised to the average value. The kinematical analysis gives a value for the elongation of the potential to be $\sim 10 % $. The mean amplitude of spatial lopsidedness is found to be $\sim 0.14$ in the inner disc, similar to the field galaxies, and is smaller by a factor of $\sim 2$ compared to the Eridanus group galaxies. It is also shown that the the average value of A$_1$ does not increase with the Hubble type, contrary to what is seen in field galaxies. We argue that the physical origin of lopsidedness in the Ursa Major group of galaxies is tidal interactions, albeit weaker and less frequent than in Eridanus. Thus systematic studies of lopsidedness in groups of galaxies can provide dynamical clues regarding the interactions and evolution of galaxies in a group environment.

description: Suppose we wish to predict the behaviour of a physical system. We may choose to represent the system by model structure $S$ (a set of related mathematical models defined by parametric relationships between system variables), and a parameter set $Θ$. Each parameter vector in $Θ$ is associated with a completely specified model in $S$. We use $S$ with system observations in estimating the "true" (unknown) parameter vector. Inconveniently, multiple parameter vectors may cause $S$ to approximate the data equally well. If we cannot distinguish between such alternatives, and these lead to dissimilar predictions, we cannot confidently use $S$ in decision making. This result may render efforts in data collection and modelling fruitless. This outcome occurs when $S$ lacks the property of structural global identifiability (SGI). Fortunately, we can test various classes of structures for SGI prior to data collection. A non-SGI result may guide changes to our structure or experimental design towards obtaining a better outcome. We aim to assist the testing of structures for SGI through bespoke Maple 2020 procedures. We consider continuous-time, uncontrolled, linear time-invariant state-space structures. Here, the time evolution of the state-variable vector ${\bf x}$ is modelled by a system of constant-coefficient, ordinary differential equations. We utilise the "transfer function" approach, which is also applicable to the "compartmental" subclass (mass is conserved). Our use of Maple's "Explore" enables an interactive consideration of a parent structure and its variants, obtained as the user changes which components of ${\bf x}$ are observed, or have non-zero initial conditions. Such changes may influence the information content of the idealised output available for the SGI test, and hence, its result. Our approach may inform the interactive analysis of structures from other classes.

description: Wie Grammatikalisierungsprozesse in natürlichen Sprachen belegen, entsteht neue Nominalmorphologie durch Nominalkomposition. Derselbe Prozess wird im Rahmen der Sprachevolution angenommen: Die Univerbierung zweier selbständiger Elemente zu einem Proto-Kompositum kann, sofern das Hinterglied generalisiert wird, zur Genese von Proto-Morphologie führen. Allerdings sind die genauen Bedingungen dieses Prozesses bislang ungeklärt. Hier setzt der vorliegende Beitrag ein: Er geht den Bedingungen dieses Prozesses auf den Grund und versetzt aufgrund theoretischer Überlegungen den Zeitpunkt der Entstehung von Morphologie in eine Phase nach dem Aufkommen erster syntaktischer Phrasenstrukturen. Dabei zeigt der Beitrag, welche unterschiedlichen Kompositionstypen bei der Entstehung von Nominalkomposition beteiligt sind, und liefert so neue Erkenntnisse zur synchronen Struktur der Determinativkomposita. Diese Erkenntnisse stärken die These, wonach Nominalkomposita der Ursprung der Derivations- und Kasusmorphologie sind.

description: Al centro di questo lavoro vi è la proposta di un intervento di facilitazione su un testo di geografia contenuto nell'Atlante online Unimondo, un sito che si rivolge a studenti delle scuole primarie e secondarie. Obiettivo di questo lavoro è individuare quelle che sono in generale le criticità dei testi disciplinari e gli ostacoli che essi pongono dinnanzi a uno studente straniero (e non solo), proponendo in seguito alcuni interventi didattici mirati ad accompagnare il discente nella comprensione del testo e nello sviluppo della lingua dello studio. Dopo aver presentato brevemente le due opzioni della semplificazione e della facilitazione e aver fatto alcune considerazioni sulla preferibilità dell’una piuttosto che dell’altra, si è preso in esame il testo in questione. Ad una dettagliata analisi linguistica delle principali difficoltà ivi contenute, segue la proposta di un percorso di facilitazione mediante attività tese a permettere allo studente un approccio di successo con il testo autentico. Obiettivo della proposta è presentare un modello applicabile ad altri testi dello stesso tipo, mirato allo sviluppo da parte dello studente di una sempre maggiore consapevolezza circa i propri processi cognitivi e le strategie di lettura che può mettere in atto, puntando verso una sempre maggiore autonomia.

Online Geography Atlas: facilitation of texts

This paper focuses on the proposal to facilitate use of a geography text contained in the online Unimondo Atlas. This site caters to primary and secondary school students. This paper aims to identify the critical aspects of disciplinary texts and the obstacles they pose to foreign students (and not only), proposing some educational interventions aimed at accompanying the student in understanding the text and in developing the language of study. After a brief presentation of two ways to simplify and facilitate the materials, and a discussion of how one or the other might be preferable, we examine the text in question. After a detailed linguistic analysis of the main difficulties, facilitation proposals include activities designed to allow the student to successfully approach the authentic text. The objective of the proposal is to present a model applicable to other texts of the same type, aimed at the student’s development of a growing awareness about their own cognitive processes and reading strategies that can be used, leading towards greater autonomy.

description: We study the effect of investor inertia on stock price fluctuations with a market microstructure model comprising many small investors who are inactive most of the time. It turns out that semi-Markov processes are tailor made for modelling inert investors. With a suitable scaling, we show that when the price is driven by the market imbalance, the log price process is approximated by a process with long range dependence and non-Gaussian returns distributions, driven by a fractional Brownian motion. Consequently, investor inertia may lead to arbitrage opportunities for sophisticated market participants. The mathematical contributions are a functional central limit theorem for stationary semi-Markov processes, and approximation results for stochastic integrals of continuous semimartingales with respect to fractional Brownian motion.

L’articolo si propone di descrivere le caratteristiche principali del TBLL e di illustrare un esempio di applicazione di didattica del task ad apprendenti di madrelingua cinese, durante un corso avanzato di italiano L2. La ricerca, inoltre, sulla base dei dati ricavati da un questionario sottoposto agli studenti del corso, dà conto delle valutazioni che essi hanno espresso rispetto alle attività sperimentate in classe. Le peculiarità di questo modello didattico sono infine messe a confronto con i tratti che caratterizzano il percorso di apprendimento degli studenti sinofoni, allo scopo di indagare sino a che punto una didattica basata sul task possa rivelarsi utile nell’insegnamento rivolto a questa specifica tipologia di apprendenti.

Tasks in teaching italian L2 to chinese students
The concept of the task is the basis of a method known as TBLL (Task-Based Language Learning) or “learning a language based on the task”. The article describes the main features of TBLL and illustrates an example of applying this method with native Chinese learners attending an advanced Italian L2 course. The research is also based on data obtained from a questionnaire evaluating the activities implemented given to the students in the course. The peculiarities of this teaching method are compared with the traits that characterize Chinese students in order to investigate the extent to which task based teaching may be useful for this specific type of learner.

Selective accent revival in Liverpool
Creators: name: Juskan, Marten
Publisher: name: JournaLIPP
Year: 2015

description: Despite the considerable stigma attached to it, many people in Liverpool have the impression that Scouse, the local accent, is getting stronger. This paper reports an apparent time study investigating whether young Liverpudlians use local variants of two consonantal variables (/ŋ(g)/ and lenition of /k/) more than older speakers and whether increased usage can be linked to decreasing salience. The data suggest that younger speakers are only “more Scouse” with respect to /k/, the variable that is part of the stereotype of the accent. The salience of this feature is actually increasing, so a very strong desire to express a local identity is a more probable cause for the change.

description: In two-dimensional (2D) metallic kagome lattice materials, destructive interference of electronic hopping pathways around the kagome bracket can produce nearly localized electrons, and thus electronic bands that are flat in momentum space. When ferromagnetic order breaks the degeneracy of the electronic bands and splits them into the spin-up majority and spin-down minority electronic bands, quasiparticle excitations between the spin-up and spin-down flat bands should form a narrow localized spin-excitation Stoner continuum coexisting with well-defined spin waves in the long wavelengths. Here we report inelastic neutron scattering studies of spin excitations in 2D metallic Kagome lattice antiferromagnetic FeSn and paramagnetic CoSn, where angle resolved photoemission spectroscopy experiments found spin-polarized and nonpolarized flat bands, respectively, below the Fermi level. Although our initial measurements on FeSn indeed reveal well-defined spin waves extending well above 140 meV coexisting with a flat excitation at 170 meV, subsequent experiments on CoSn indicate that the flat mode actually arises mostly from hydrocarbon scattering of the CYTOP-M commonly used to glue the samples to aluminum holder. Therefore, our results established the evolution of spin excitations in FeSn and CoSn, and identified an anomalous flat mode that has been overlooked by the neutron scattering community for the past 20 years.

description: A fully-resolved direct-numerical-simulation (DNS) approach for investigating flexible bodies forced by a turbulent incoming flow is designed to study the flapping motion of a flexible flag at moderate Reynolds number. The incoming turbulent flow is generated by placing a passive grid at the inlet of the numerical domain and the turbulence level of the flow impacting the flag can be controlled by changing its downstream distance from the grid. The computational framework is based on the immersed boundary method for dealing with arbitrary geometries and implemented using a graphics-processing-unit (GPU) accelerated parallelisation to increase the computational efficiency. The grid-induced turbulent flow is first characterised by means of the comparison with well-known results for decaying turbulence and a scale-by-scale analysis. Then, the flag-in-the-wind problem is revisited by exploring the effect of the turbulence intensity on self-sustained flapping. Whilst the latter is still manifesting under strong fluctuations, the main features of the oscillation (including its amplitude and frequency) are altered by turbulence, whose fingerprint can also be qualitatively detected by spectral analysis. Besides their relevance for advancing the fundamental understanding of fluid-structure interaction in turbulence, these findings have potential impact for related applications, e.g., aeroelastic energy harvesting or flow control techniques.

An angular power spectrum analysis of the DRAO 1.4 GHz polarization survey: implications for CMB observations

description: The aim of the present analysis is to improve the knowledge of the statistical properties of the Galactic diffuse synchrotron emission, which constrains sensitive CMB anisotropy measurements. We have analysed the new DRAO 1.4 GHz polarization survey together with the Stockert 1.4 GHz total intensity survey and derived the angular power spectra (APSs) of the total intensity, the polarized emission, and their cross-correlation for the entire surveys and for three low-intensity regions. The APSs of the diffuse synchrotron emission are modelled by power laws. For the $E$ and $B$ modes, a slope of $α\sim [-3.0,-2.5]$ for the multipole range $\sim [30,300]$ is found. By the extrapolation of these results to 70 GHz, we can estimate the Galactic synchrotron contamination of CMB anisotropies, and we find results that are compatible with the ones coming from WMAP 3-yr data. In the low-intensity regions, the cosmological primordial B~mode peak at $\ell \sim 100$ should be clearly observable for a tensor-to-scalar ratio $T/S \gsim 0.5$ and a synchrotron temperature spectral index $β\sim -3$. Its detection is also possible for $T/S \gsim 0.005$ and $β\sim -3$, in case a separation of the foreground from the CMB signal could be achieved with an accuracy of $\sim 5-10%$. For the TE mode, a mask excluding $|b_{gal}| \le 5^{\circ}$ (for $β\sim -3.0$) or $|b_{gal}| \le 20^{\circ}$ (for $β\sim -2.8$) from the surveys is sufficient to render the foreground contamination negligible, thus confirming the ability of WMAP to have a clear view of the temperature-polarization correlation peak and antipeak series.

description: A robotic system continuously measures its own motions and the external world during operation. Such measurements are with respect to some frame of reference, i.e., a coordinate system. A nontrivial robotic system has a large number of different frames and data have to be translated back-and-forth from a frame to another. The onus is on the developers to get such translation right. However, this is very challenging and error-prone, evidenced by the large number of questions and issues related to frame uses on developers' forum. Since any state variable can be associated with some frame, reference frames can be naturally modeled as variable types. We hence develop a novel type system that can automatically infer variables' frame types and in turn detect any type inconsistencies and violations of frame conventions. The evaluation on a set of 180 publicly available ROS projects shows that our system can detect 190 inconsistencies with 154 true positives. We reported 52 to developers and received 18 responses so far, with 15 fixed/acknowledged. Our technique also finds 45 violations of common practices.

description: The technique of low-temperature Laser Scanning Microscopy (LSM) has been applied to the investigation of local microwave properties in operating YBa2Cu3O7/LaAlO3 thin-film resonators patterned into a meandering strip transmission line. By using a modified newly developed procedure of spatially-resolved complex impedance partition, the influence of inhomogeneous current flow on the formation of nonlinear (NL) microwave response in such planar devices is analyzed in terms of the independent impact from resistive and inductive components. The modified procedure developed here is dramatically faster than our previous method. The LSM capability to probe the spatial variations of two-tone, third-order intermodulation currents on micron length scales is used to find the 2D distribution of the local sources of microwave NL. The results show that the dominant sources of microwave NL are strongly localized in the resistive domains.

description: This diploma thesis deals with the effect of noise on synchronous circuits for secure data transmission. The aim of the work is to familiarize the reader with the basic concepts of chaos theory regarding chaotic communications, such as chaotic systems, strange attractors and synchronization, and the application of these concepts to a communications security system, which consists of a transmitter and a receiver. This diploma thesis studies in details the pulsed synchronization between two electrical circuits based on the chaotic Chen-Lee system. The digital implementation of the pulsed synchronization was accomplished using the Multisim 13.0 circuit design and simulation program. The results of the simulations verify the functionality of the circuit in the form proposed in the diploma thesis for the creation of a secure communication system. Although the experimental study was entirely implemented in a circuit design and simulation program, it is a realistic approach that it can soon acquire in addition to digital and physical implementation

description: We have made a comprehensive transit search for exoplanets down to about 2 Earth radii in the HD 209458 system, based on nearly uninterrupted broadband optical photometry obtained with the MOST (Microvariability and Oscillations of Stars) satellite, spanning 14 days in 2004 and 44 days in 2005. We have searched these data for limb-darkened transits at periods other than that of the known giant planet, from about 0.5 days to 2 weeks. Monte Carlo statistical tests of the data with synthetic transits inserted allow us to rule out additional close-in exoplanets with sizes ranging from about 0.20-0.36 RJ (Jupiter radii), or 2.2-4.0 RE (Earth radii) on orbits whose planes are near that of HD 209458b. These null results constrain theories that invoke lower mass planets in orbits similar to HD 209458b to explain its anomalously large radius, and those that predict "hot Earths" due to the inward migration of HD 209458b.

description: Various model problems of ``transport-limited dissolution'' in two dimensions are analyzed using time-dependent conformal maps. For diffusion-limited dissolution (reverse Laplacian growth), several exact solutions are discussed for the smoothing of corrugated surfaces, including the continuous analogs of ``internal diffusion-limited aggregation'' and ``diffusion-limited erosion''. A class of non-Laplacian, transport-limited dissolution processes are also considered, which raise the general question of when and where a finite solid will disappear. In a case of dissolution by advection-diffusion, a tilted ellipse maintains its shape during collapse, as its center of mass drifts obliquely away from the background fluid flow, but other initial shapes have more complicated dynamics.

description: Text encoding is one of the most important steps in Natural Language Processing (NLP). It has been done well by the self-attention mechanism in the current state-of-the-art Transformer encoder, which has brought about significant improvements in the performance of many NLP tasks. Though the Transformer encoder may effectively capture general information in its resulting representations, the backbone information, meaning the gist of the input text, is not specifically focused on. In this paper, we propose explicit and implicit text compression approaches to enhance the Transformer encoding and evaluate models using this approach on several typical downstream tasks that rely on the encoding heavily. Our explicit text compression approaches use dedicated models to compress text, while our implicit text compression approach simply adds an additional module to the main model to handle text compression. We propose three ways of integration, namely backbone source-side fusion, target-side fusion, and both-side fusion, to integrate the backbone information into Transformer-based models for various downstream tasks. Our evaluation on benchmark datasets shows that the proposed explicit and implicit text compression approaches improve results in comparison to strong baselines. We therefore conclude, when comparing the encodings to the baseline models, text compression helps the encoders to learn better language representations.

description: The rate of the non-perturbative decay of a 't Hooft - Polyakov monopole in an external electric field into a dyon and a charged fermion is calculated. The subleading semiclassical prefactor is presented for the first time for this process. The leading exponential factor is shown to be in full agreement with the previous results derived in a different technique. Analogous treatment is shown to hold for the two-fermionic decay of the lightest bound state in Thirring model, allowing one to restore the "effective meson - fermion vertex".

description: We identify a class of modal solutions for spatio-temporal optical vortex (STOV) electromagnetic pulses propagating in dispersive media with orbital angular momentum (OAM) orthogonal to propagation. We find that symmetric STOVs in vacuum can carry half-integer intrinsic orbital angular momentum (OAM); for general asymmetric STOVs in a dispersive medium, the OAM is quantized in integer multiples of a parameter that depends on the STOV symmetry and the group velocity dispersion. Our results suggest that STOVs propagating in dispersive media are accompanied by a polariton-like quasiparticle. The modal theory is in excellent agreement with measurements of free space propagation of STOVs.

The effect of carotid sinus pressure on the osmoregulation of arginine vasopressin in anesthetized rabbits
Creators: name: Scott, Christine Sharon
Publisher: name: University of British Columbia
Year: 2008

description: Studies in rat, dog and human show that changes in blood volume influence the relationship between plasma osmolality and plasma arginine vasopressin (AVP) concentration. It has not been proven whether the change in blood volume acts through stimulation of the low pressure receptors or arterial baroreceptors or both. The purpose of these experiments was to investigate the effect of changes in arterial baroreceptor stimulation on the relationship between plasma osmolality and plasma AVP in the anesthetized, artificially ventilated rabbit. Both carotid sinuses were isolated and perfused with blood at servo-controlled pressures of 40, 100, or 140 mmHg. The vagus and aortic depressor nerves were sectioned bilaterally to eliminate input from a trial and aortic arch baroreceptors. Saline (0.3%) was infused i.v. to lower plasma osmolality and 5% saline was infused to r a i s e plasma osmolality. At low (288 + 1 mosm/kg), medium (309 ± 1 mosm/kg) and high (323 + 1 mosm/kg) plasma osmolality, the carotid sinus pressure was changed from 100 mmHg t o 40 mmHg, to 140 mmHg and returned to 100 mmHg. Arterial blood samples were taken at each carotid sinus pressure 7 minutes after the change in pressure. Plasma immunoreactive AVP (iAVP) was measured by radioimmunoassay. At medium (309 mosm/kg) and high (323 mosm/kg) plasma osmolality, the levels of plasma AVP were higher at CSP 40 mmHg than at CSP 140 mmHg. The relationship between plasma iAVP and plasma osmolality was expressed as a linear regression at each of the carotid sinus pressures. The slope of the regression line at CSP 40 mmHg was greater than it was at CSP 140 mmHg. The x-intercepts of the regression lines were not significantly different. In the control rabbits, in which CSP was maintained constant at 100 mmHg, the slope of the AVP/Posm relationship was the same as that in the experimental animals at the same CSP. These results indicate that arterial baroreceptors, acting alone, can change the slope of the AVP/Posm relationship. Changes in carotid sinus pressure appear t o change the sensitivity but not the threshold of the osmotic control of AVP release.

EARLY CARIES DETECTION, DIAGNOSIS, AND MONITORING: PAVING THE WAY FOR PERSONALIZED DENTAL CARE
Creators: name: Radjabov, Alisher
Publisher: name: Zenodo
Year: 2025

description: Dental caries continues to be a major global health concern. The World Health Organization’s 2022 reports emphasize that despite significant efforts and scientific progress in caries detection and management, the overall situation has shown only minimal improvement over the past three decades. This persistence may be attributed to outdated concepts, developed nearly a century ago, that still influence modern approaches to caries management. There is an urgent need to rethink professional strategies for preventing and managing caries. Modern dentistry has the potential to greatly benefit from adopting innovative concepts and advanced technologies for caries detection and treatment. Among these, optical-based caries detection methods, which have been established for over a decade, align with contemporary understandings of the disease and adhere to international recommendations emphasizing early detection and minimally invasive management. This narrative review explores the current state of knowledge and recent advances in caries detection, diagnosis, monitoring, and management, while offering insights into future directions for clinical practice and research.
Radial Velocities of Stars in the Galactic Center

description: We present results from K band slit scan observations of a ~20''x20'' region of the Galactic center (GC) in two separate epochs more than five years apart. The high resolution (R>=14,000) observations allow the most accurate radial velocity and acceleration measurements of the stars in the central parsec of the Galaxy. Detected stars can be divided into three groups based on the CO absorption band heads at ~2.2935 microns and the He I lines at ~2.0581 microns and ~2.112, 2.113 microns: cool, narrow-line hot and broad-line hot. The radial velocities of the cool, late-type stars have approximately a symmetrical distribution with its center at ~-7.8(+/-10.3) km/s and a standard deviation ~113.7(+/-10.3) km/s. Although our statistics are dominated by the brightest stars, we estimate a central black hole mass of 3.9(+/-1.1) million solar masses, consistent with current estimates from complete orbits of individual stars. Our surface density profile and the velocity dispersion of the late type stars support the existence of a low density region at the Galactic center suggested by earlier observations. Many hot, early-type stars show radial velocity changes higher than maximum values allowed by pure circular orbital motions around a central massive object, suggesting that the motions of these stars greatly deviate from circular orbital motions around the Galactic center. The correlation between the radial velocities of the early type He I stars and their declination offsets from Sagittarius A* suggests that a systematic rotation is present for the early-type population. No figure rotation around the Galactic center for the late type stars is supported by the new observations.

description: We solve the problem of discrete translocation of a polymer through a pore, driven by the irreversible, random sequential adsorption of particles on one side of the pore. Although the kinetics of the wall motion and the deposition are coupled, we find the exact steady-state distribution for the gap between the wall and the nearest deposited particle. This result enables us to construct the mean translocation velocity demonstrating that translocation is faster when the adsorbing particles are smaller. Monte-Carlo simulations also show that smaller particles gives less dispersion in the ratcheted motion. We also define and compare the relative efficiencies of ratcheting by deposition of particles with different sizes and we describe an associated "zone-refinement" process.
