description: Μία από τις μεγαλύτερες προκλήσεις στην εκμάθηση ξένης γλώσσας είναι η απόκτηση λεξιλογίου. Το γεγονός αυτό καθιστά την μελέτη των μεθόδων που θα εξασφαλίσουν γρήγορη απόκτηση λέξεων στην ξένη γλώσσα, πολύ σημαντική. Στόχος της παρούσας έρευνας ήταν να αντιπαραθέσει δυο μεθόδους εκμάθησης ξένης γλώσσας και να διερευνήσει ποιά από τις δυο μεθόδους είναι πιο αποτελεσματική στην εκμάθηση νέου λεξιλογίου σε μια ξένη γλώσσα, συγκεκριμένα στην αγγλική. Οι μέθοδοι εκμάθησης που αντιπαρατέθηκαν είναι: η τεχνική της επαναλαμβανόμενης ανάσυρσης (retrieval practice), μιας τεχνικής που βασίζεται στην διεξαγωγή επαναλαμβανόμενων εξετάσεων με σκοπό την εκμάθηση του υλικού και η μέθοδος «λέξη-κλειδί» (keyword method), μια καλά εδραιωμένη τεχνική με βάση τις εικόνες για την εξασφάλιση λεξιλογίου. Ειδικότερα, διερευνήθηκε ποιά από τις δυο οδηγεί τόσο σε άμεση απόκτηση περισσότερων νέων λέξεων στα αγγλικά όσο και σε μακροχρόνια μάθηση που είναι παγιωμένη και ανθεκτική σε βάθος χρόνου. Στο δείγμα συμμετείχαν 63 φοιτητές του Τμήματος Ψυχολογίας του Αριστοτελείου Πανεπιστήμιου Θεσσαλονίκης. Τα αποτελέσματα της έρευνας έδειξαν ότι η μέθοδος «λέξη – κλειδί» είναι πιο αποτελεσματική στην άμεση απόκτηση νέων λέξεων. Ωστόσο, καμία από τις δυο μεθόδους δεν επέφερε στατιστικά σημαντικά αποτελέσματα στην μακρόχρονη συγκράτηση των αγγλικών λέξεων.
description: One of the biggest challenges in learning a foreign language is to acquire a vocabulary. This makes studying methods that will ensure fast acquisition of foreign language words, very important. The purpose of this research was to contrast two methods of foreign language learning and to explore which of the two methods is more effective in learning a new vocabulary in a foreign language, namely English. The recited methods of learning are: the technique of retrieval practice, a technique based on conducting recurrent material learning exams and the keyword method, a well-established technique based on images to obtain vocabulary. In particular, it has been investigated which of the two leads both to the immediate acquisition of more new words in English and to long-term learning that is well-established and durable in the long run. The sample was attended by 63 students from the Department of Psychology of the Aristotle University of Thessaloniki. The results of the survey showed that the keyword method is more effective in acquiring new words. However, none of the two methods produced statistically significant results in the long-term containment of English words.

description: This research case study assesses the impacts of peri-urban features such as buildings on the performance of an operating 850 kW Vestas V52 wind turbine that has a 60 m hub height and 52 m rotor diameter located at the outskirts of Dundalk town in Ireland. Multi-annual 10-minute SCADA data is analysed to assess the directional electrical energy rose (EER) of the wind turbine. This is compared to predictions from WAsP-IBZ that uses an obstacle model to assess buildings and to WAsP-CFD treating buildings as surface roughness elements in the terrain. Onsite LiDAR measurements are used to initialise the WAsP programme in both cases. Measured directional wind shear profiles are also assessed to give further insights into discrepancies between the predicted and actual energy performance of the wind turbine.

The lepton fields are represented as a doublet of SU(2)for both left and right fields. By using the pattern of symmetry breaking emerges as the minimum of the Higgs potential for a range of parameters, we show that the domination of the V-A over V+A interactions is natural at low energy. The symmetry breaking is the responsible mechanism for the up-down lepton doublet mass difference

description: We construct a discrete family of smooth non-supersymmetric three charge geometries carrying D1 brane, D5 brane and Kaluza-Klein monopole charges in Type IIB supergravity compactified on a six-torus, which can be interpreted as the geometric description of some special states of the brane system. These solutions are asymptotically flat in four dimensions, and generalise previous supersymmetric solutions. The solutions have a qualitatively similar structure to previous non-supersymmetric smooth solutions carrying D1 and D5 brane charges in five dimensions, and indeed can be viewed as the five-dimensional system placed at the core of a Kaluza-Klein monopole. The geometries are smooth, free of horizons and do not have closed timelike curves. One notable difference from the five-dimensional case is that the four-dimensional geometry has no ergoregion.

A discontinuity in the luminosity-mass relation and fluctuations in the evolutionary tracks of low-mass and low-metallicity stars at the Gaia M-dwarf gap

description: The Gaia M-dwarf gap is a recently discovered feature in the colour-magnitude diagram that shows a deficiency of low-mass and low-metallicity stars at the lower end of the main sequence. We aim at performing theoretical stellar modelling at low metallicities using a fine mass step and a fine time step, looking specifically for the transition of models from partially to fully convective, since the convective kissing instability that occurs at this transition is believed to be the cause of the gap. Stellar evolution models with metallicities of Z = 0.01, Z = 0.001 and Z = 0.0001 are performed using MESA, with a mass step of 0.00025 M$_{\odot}$ and a time step of 50,000 years. The small time step produced models that experience loops in their evolutionary tracks in the Hertzsprung-Russell (HR) diagram. The fluctuations in effective temperature and luminosity correspond to repeated events in which the bottom of the convective envelope merges with the top of the convective core, transporting $^3$He from the core to the surface. In addition to the episodes of switching from partially to fully convective, several near-merger events that produced low amplitude fluctuations were also found. Low-metallicity models undergo the convective kissing instability for longer portions of their lifetime and with higher fluctuation amplitudes than models with higher metallicities. The small mass step used in the models revealed a discontinuity in the luminosity-mass relation at all three metallicities.

In the construction we use tangential edge bubble functions for the divergence correcting operator. This naturally leads to an alternative inf-sup stable reduced finite element pair. Furthermore, we provide a counterexample to the inf-sup stability and hence to existence of a Fortin operator for the $P_2$-$P_0$ and the augmented Taylor-Hood element in 3D.

We also use our result to prove congruences of Bernoulli-Hurwitz numbers at non-ordinary (i.e. supersingular) primes originally investigated by Katz and Chellali.

description: No abstracts are to be cited without prior reference to the author.The structure, morphology and spatio-temporal distribution of pelagic schools are studied on an historical acoustic data base in Eastern Venezuela (7 surveys, 1985-1988). The school types are classified according to a typology established in Senegal on the same main species (Sardinella aurita). The school distribution is correlated with several environmental parameters : season, hour, depth, main hydrological characteristics. An average of 800 schools per survey are analysed. Within the main results, we may point out that Venezuelan populations present less school types than in Senegal (two of 7 were not encountered) ; school types seems more related to geographic (i.e. hydrological) conditions, than to seasonal differences : in particular some areas in Eastern Venezuela present very characteristic distribution (Gulf of Paria, influenced by the Orinoco delta); changes in school types proportion are observed during daily cycles. Comparisons between the data base and other acoustic and fishing data, from Senegal or from recent surveys in Venezuela, lead to the hypothesis than certain school structures could be species dependent ( e.g. « compact schools » from Sardinella aurita, « tower schools» from S. maderensis).

description: In recent years there has been considerable progress in our understanding of the nature and properties of the reionization process. In particular, the numerical simulations of this epoch have made a qualitative leap forward, reaching sufficiently large scales to derive the characteristic scales of the reionization process and thus allowing for realistic observational predictions. Our group has recently performed the first such large-scale radiative transfer simulations of reionization, run on top of state-of-the-art simulations of early structure formation. This allowed us to make the first realistic observational predictions about the Epoch of Reionization based on detailed radiative transfer and structure formation simulations. We discuss the basic features of reionization derived from our simulations and some recent results on the observational implications for the high-redshift Ly-alpha sources.

The .linked issue of scale poses a further conceptual challenge, since our perception and mechanistic. understanding· of spatial variability in populations may be sensitive to the scale of observation, and can detrimentally affect the (ormulation of robust scientific management advice.· Yet comparatively little is known about the form of spatial variability exhibited by .marine populations .and the processes. that generate them. This study analyses spatial patterns in commercially harvested assemblages of the flat oyster ( Ostrea edulis) in the Solent, an extended estuarine system in southern England. Emphasis is placed on the linking of diver, grab and dredge data sets spanning a wide range of spatial scales, and the characterisation .of abundance variance scaling properties within. individual oyster beds. Results demonstrate ubiquitous conformity to power law scaling,. the hallmark of scale invariant patterning. Consistent values for the scaling exponent are obtained over spatial scales spanning more than 3 orders of magnitude, despite significant regional differences in hydrography, substrate, benthic community composition, harvesting rates and oyster density. Po.ssible structuring mechanisms are proposed. Findings are discussed in the. context of studies on patchiness in planktonic assemblages and recent work on spatial variability in fish populations.

description: Atom probe tomography is a powerful tools in investigating nanostructures such as interfaces and nanoparticles in material science. Advanced analysis tools are particularly useful for analyzing these nanostructures characterized very often by curved shapes. However, these tools are very limited for complex materials with non-negligible peak overlaps in their respective mass-to-charge ratio spectra. Usually, an analyst solves peak overlaps in the bulk regions but the behavior at interfaces is rarely considered. Therefore, in this work we demonstrate how the proximity histogram generated for a specific interface can be corrected by using the natural abundances of isotopes. This leads to overlap-solved proximity histograms with a resolution of up to 0.1 nm. This work expands on previous work that showed the advantage of a maximum likelihood peak overlap solving. The corrected proximity histograms together with the maximum likelihood peak overlap algorithm were implemented in an user-friendly software suite called EPOSA.

description: We study the enumerative geometry of the moduli space R_g of Prym varieties of dimension g-1 (also known as the space of admissible double covers). Our main result is that the compactification of R_g is of general type as soon as g>13. We achieve this by computing the class of two types of cycles on R_g: one defined in terms of Koszul cohomology of Prym curves, the other defined in terms of Raynaud theta divisors associated to certain vector bundles on curves. We formulate a Prym-Green conjecture on syzygies of Prym-canonical curves. In the appendix we show that even though R_g has non-canonical singularities, pluricanonical forms on R_g extend to any desingularization.

description: No abstracts are to be cited without prior reference to the author.The present study aims to measure the impact of this abundance spatial heterogeneity on the efficiency of different kinds of fishing tactics. In this goal, a multi-agent simulator is implemented, in which the harvesting activity of a fleet is simulated and coupled to the spatial dynamics of a virtual fish population, in a bi-dimensional spatially explicit environment. Simulations, as an exploratory tool, lead us to experiment different scenarii, in which different fishing tactics are applied by the fleet to a given resource distribution.

description: We have calculated the atomic electric dipole moments (EDMs) d of ^3He and ^{171}Yb induced by their respective nuclear Schiff moments S. Our results are d(He)= 8.3x10^{-5} and d(Yb)= -1.9 in units 10^{-17}S/(e{fm}^3)e cm. By considering the nuclear Schiff moments induced by the parity and time-reversal violating nucleon-nucleon interaction we find d(^{171}Yb)~0.6d(^{199}Hg). For ^3He the nuclear EDM coupled with the hyperfine interaction gives a larger atomic EDM than the Schiff moment. The result for ^3He is required for a neutron EDM experiment that is under development, where ^3He is used as a comagnetometer. We find that the EDM for He is orders of magnitude smaller than the neutron EDM. The result for Yb is needed for the planning and interpretation of experiments that have been proposed to measure the EDM of this atom.

description: Efficient control of a magnetization without an application of the external magnetic fields is the ultimate goal of spintronics. We demonstrate, that in monolayers of $\text{CrI}_3$, magnetization can be switched all optically, by application of the resonant pulses of circularly polarized light. This happens because of the efficient coupling of the lattice magnetization with bright excitonic transition. $\text{CrI}_3$ is thus perspective functional material with high potential for applications in the domains of spintronics and ultra-fast magnetic memory.
Cycle-to-cycle variations in spark-ignition engines
Creators: name: Kapil, Anil
Publisher: name: University of British Columbia
Year: 2010

description: Pressure data measurements have been made in a single-cylinder, spark-ignition engine over 100 consecutive cycles. The engine was operated on natural gas at a wide range of engine speed and equivalence ratios. The effects of spark electrode geometry, combustion chamber geometry, spark gap and throttling have also been examined. From these pressure measurements standard deviations in burning times in mass-fraction-burned values were determined. Because of the existing evidence that the origin of cyclic variations is in the early combustion period, the standard deviations of cyclic variation in time required for a small (almost zero) mass-fraction-burned is estimated by extrapolation. These extrapolated values of standard deviation are compared with the implication of a hypothesis that cyclic variations in combustion in spark-ignition engines originate in the small-scale structure of turbulence (after ignition). The nature of turbulence structure during combustion is deduced from existing knowledge of mixture motion within the combustion chamber of the engine. This research determines the turbulent parameters, such as turbulence intensity, turbulent length scales and laminar burning velocity. The standard deviation in burning times in the early stages of combustion is estimated, within experimental uncertainty, by the parameter ⋋/4uℓ where ⋋ is the Taylor microscale and uℓ is the laminar burning velocity of the unburned mixture. This parameter is the consequence of the Tennekes model of small-scale structure of turbulence and Chomiak's explanation of the high flame propagation rate in regions of concentrated vorticity and the assumption that theignition behaves as though it were from a point source. The general conclusion reached is that the standard deviation in the burning time for small mass-fraction-burned is associated with the early stages of burning-predictable from the knowledge of the Taylor microscale and the laminar burning velocity.

description: We study mesoscopic disorder fluctuations in an anisotropic gap superconductor, which lead to the spatial variations of the local pairing temperature and formation of superconducting islands above the mean-field transition. We derive the probability distribution function of the pairing temperatures and superconducting gaps. It is shown that above the mean-field transition, a disordered BCS superconductor with an unusual pairing symmetry is described by a network of superconducting islands and metallic regions with a strongly suppressed density of states due to superconducting fluctuations. We argue that the phenomena associated with mesoscopic disorder fluctuations may also be relevant to the high-temperature superconductors, in particular, to recent STM experiments, where gap inhomogeneities have been explicitly observed. It is suggested that the gap fluctuations in the pseudogap phase should be directly related to the corresponding fluctuations of the pairing temperature.

description: Recommendation and ranking systems are known to suffer from popularity bias; the tendency of the algorithm to favor a few popular items while under-representing the majority of other items. Prior research has examined various approaches for mitigating popularity bias and enhancing the recommendation of long-tail, less popular, items. The effectiveness of these approaches is often assessed using different metrics to evaluate the extent to which over-concentration on popular items is reduced. However, not much attention has been given to the user-centered evaluation of this bias; how different users with different levels of interest towards popular items are affected by such algorithms. In this paper, we show the limitations of the existing metrics to evaluate popularity bias mitigation when we want to assess these algorithms from the users' perspective and we propose a new metric that can address these limitations. In addition, we present an effective approach that mitigates popularity bias from the user-centered point of view. Finally, we investigate several state-of-the-art approaches proposed in recent years to mitigate popularity bias and evaluate their performances using the existing metrics and also from the users' perspective. Our experimental results using two publicly-available datasets show that existing popularity bias mitigation techniques ignore the users' tolerance towards popular items. Our proposed user-centered method can tackle popularity bias effectively for different users while also improving the existing metrics.

We here present individual based single speeies and mu:itispecies models where spatial behaviour and life history strategies are evolved( Spatial movement for each fish is calculated using an artificial neural network·with weights evolved by a genetic algorithm. Behaviour relies on sensory information about food, .temperature, light and predators. A concept for modelling life ·history strategies and migration in fish using this method is presented along with an application of this concept for the Barents Sea capelin. A predator-prey model based on the same principle is also presented. Potential areas of application for these kinds of models are discussed:

description: This article describes a technique to augment a typical RGBD sensor by integrating depth estimates obtained via Structure-from-Motion (SfM) with sensor depth measurements. Limitations in the RGBD depth sensing technology prevent capturing depth measurements in four important contexts: (1) distant surfaces (>5m), (2) dark surfaces, (3) brightly lit indoor scenes and (4) sunlit outdoor scenes. SfM technology computes depth via multi-view reconstruction from the RGB image sequence alone. As such, SfM depth estimates do not suffer the same limitations and may be computed in all four of the previously listed circumstances. This work describes a novel fusion of RGBD depth data and SfM-estimated depths to generate an improved depth stream that may be processed by one of many important downstream applications such as robotic localization and mapping, as well as object recognition and tracking.

description: No abstracts are to be cited without prior reference to the author.A large concentration of wintering herring was surveyed continuously with acoustics over 37 hours in ·a fjord in Northern Norway. 16 surveys of the same area were conducted. Total abundance and statistics were computed for each survey. Distribution graphs showed a clear diel variation, with deep daytime layers and more shallow night time distribution. Acoustically measured abundance at night was 50% of the daytime values. The results are discussed in terms of behaviour induced diel variation in acoustic backscattering, and potential influence on acoustic abundance measurements.

description: In the present work, we investigate the universe dominated by quintom or hessence energies in Loop Quantum Cosmology (LQC). Interestingly enough, we find that there are some stable attractors in these two cases. In the case of quintom, all stable attractors have the feature of decelerated expansion. In the case of hessence, most of stable attractors have the feature of decelerated expansion while one stable attractor can have decelerated or accelerated expansion depend on the model parameter. In all cases, the equation-of-state parameter (EoS) of all stable attractors are larger than -1 and there is no singularity in the finite future. These results are different from the dynamics of phantom in LQC, or the ones of phantom, quintom and hessence in classical Einstein gravity.

description: Number-resolving photo-detection is necessary for many quantum optics experiments, especially in the application of entangled state preparation. Several schemes have been proposed for approximating number-resolving photo-detection using non-number-resolving detectors. Such techniques include multi-port detection and time-division multiplexing. We provide a detailed analysis and comparison of different number-resolving detection schemes, with a view to creating a useful reference for experimentalists. We show that the ideal architecture for projective measurements is a function of the detector's dark count and efficiency parameters. We also describe a process for selecting an appropriate topology given actual experimental component parameters.

description: We present a combined analytical and numerical investigation to show how an optimal control field can be designed to generate maximum field-free orientation of molecules for three populated rotational states. Based on a model involving pure rotational ladder-climbing excitation between rotational states, a set of optimal amplitude and phase conditions are analytically derived for the applied control fields. The maximum degree of orientation can be achieved when the field satisfies amplitude and phase conditions at the two transition frequencies. Multiple optimal solutions exist and to examine these conditions, we devise a quantum coherent control scheme using two terahertz pulses and successfully apply it to the linear polar molecule HCN at ultracold temperature. The sensitivity of both populations and phases of rotational states to control field parameters, i.e., the detuning, bandwidth, and time delay, is analyzed for understanding the optimal orientation mechanism. This work thus examines the frequency domain landscape belonging to optimal pulses.

description: No abstracts are to be cited without prior reference to the author.The spatio-temporal dynamics of the spawning process were investigated in shallow waters (~50 m) for a single medium sized school (~5 tons) of Norwegian spring spawning herring (Clupea harengus). School dynamic parameters, e.g school area, density, vertical extension, shape and movements observed with sonar and echosounder were related to biological parameters such as gonad maturation and stomach fullness obtillned from gillnet samples throughout the spawning process.
How much of the inflaton potential do we see?

description: We discuss the latest constraints on a Taylor-expanded scalar inflaton potential, obtained focusing on its observable part only. This is in contrast with other works in which an extrapolation of the potential is applied using the slow-roll hierarchy. We find significant differences. The results discussed here apply to a broader range of models, since no assumption about the invisible e-folds of inflation has to be made, thereby remaining conservative.

Number fluctuations induce persistent congestion

description: The capacity of a street segment quantifies the maximal density of vehicles before congestion arises. Here we show in a simple mathematical model that fluctuations in the instantaneous number of vehicles entering a street segment are sufficient to induce persistent congestion. Congestion emerges even if the average flow is below the segment's capacity where congestion is absent without fluctuations. We explain how this fluctuation-induced congestion emerges due to a self-amplifying reduction of the average vehicle velocities.

description: No abstracts are to be cited without prior reference to the author.Point process methodology seems very promising to identify and describe low-density layers of fish by their spatial distribution using the three-dimensional information of single fish obtained by a split-beam echo sounder. The spatial distribution of single fish within a pelagic and a demersal layer at one location in the North Sea were described/analysed. In the pelagic layer, mainly composed of herring and sandeel, the conditional distribution of number of fish given the depth was suitably modelled by a Poisson distribution with rate dependent on depth. In the demersal layer, mainly composed of whiting, haddock, and Norway pout, the same model did not apply due to fish aggregating in clusters. Modelling of spatially distributed data have gained much attention during recent years because of its potential for revealing correlation structures among dispersed observations. In the present study a special kind of Cox processes was used in which the density of fish in a particular region is described by a log Normal process. An advantage of this approach is the ability to use different functional forms for the correlation structure. The model is thus very flexible and can be used with widely different spatial patterns. The aggregations of fish were in this context, related to environmental factors in a general sense, rather than to intrinsic fish behaviour.

description: Data sampling acts as a pivotal role in training deep learning models. However, an effective sampling schedule is difficult to learn due to the inherently high dimension of parameters in learning the sampling schedule. In this paper, we propose an AutoSampling method to automatically learn sampling schedules for model training, which consists of the multi-exploitation step aiming for optimal local sampling schedules and the exploration step for the ideal sampling distribution. More specifically, we achieve sampling schedule search with shortened exploitation cycle to provide enough supervision. In addition, we periodically estimate the sampling distribution from the learned sampling schedules and perturb it to search in the distribution space. The combination of two searches allows us to learn a robust sampling schedule. We apply our AutoSampling method to a variety of image classification tasks illustrating the effectiveness of the proposed method.

description: We present detailed fits of the spectral energy distributions (SEDs) of four submillimeter (submm) galaxies selected by the presence of a gamma-ray burst (GRB) event (GRBs 980703, 000210, 000418 and 010222). These faint ~3 mJy submm emitters at redshift ~1 are characterized by an unusual combination of long- and short-wavelength properties, namely enhanced submm and/or radio emission combined with optical faintness and blue colors. We exclude an active galactic nucleus as the source of long-wavelength emission. From the SED fits we conclude that the four galaxies are young (ages <2 Gyr), highly starforming (star formation rates ~150 MSun/yr), low-mass (stellar masses ~10^10 MSun) and dusty (dust masses ~3x10^8 MSun). Their high dust temperatures (Td>45 K) indicate that GRB host galaxies are hotter, younger, and less massive counterparts to submm-selected galaxies detected so far. Future facilities like Herschel, JCMT/SCUBA-2 and ALMA will test this hypothesis enabling measurement of dust temperatures of fainter GRB-selected galaxies.
