description: We demonstrate single layer graphene/n-Si Schottky junction solar cells that under AM1.5 illumination exhibit a power conversion efficiency (PCE) of 8.6%. This performance, achieved by doping the graphene with bis(trifluoromethanesulfonyl)amide, exceeds the native(undoped) device performance by a factor of 4.5 and the best previously reported PCE in similar devices by a factor of nearly 6. Current-voltage, capacitance-voltage and external quantum efficiency measurements show the enhancement to be due to the doping induced shift in the graphene chemical potential which increases the graphene carrier density (decreasing the cell series resistance) and increases the built-in potential.

description: The periodic Toda lattice is solved by exploiting the spectral properties of the Lax operator, in which the boundary states play an important role. We show that these boundary states have a topological origin similar to that of the edge states in topological insulators, and consequently, that the bulk wave functions of the Lax operator yield nontrivial Chern numbers. This implies that the periodic Toda lattice belongs to the same topological class as the Thouless pump. We demonstrate that the cnoidal wave of the Toda lattice exhibits a Chern number of $-1$ per period.

description: It is shown that the mixing of lepton doublets of the Standard Model can yield sizeable contributions to the lepton asymmetry, that is generated through the decays of right-handed neutrinos at finite temperature in the early Universe. When calculating the flavour-mixing correlations, we account for the effects of Yukawa as well as of gauge interactions. We compare the freeze-out asymmetry from lepton-doublet mixing to the standard contributions from the mixing and direct decays of right-handed neutrinos. The asymmetry from lepton mixing is considerably large when the mass ratio between the right-handed neutrinos is of order of a few, while it becomes Maxwell-suppressed for larger hierarchies. For an intermediate range between the case of degenerate right-handed neutrinos (resonant Leptogenesis) and the hierarchical case, lepton mixing can yield the main contribution to the lepton asymmetry.

description: This D2.3 Meta Report of the YouCount Experiences with Case Study Implementation is rooted in WP2 and the implementation of hands-on youth citizen social science (Y-CSS).  In particular it addresses the work of Tasks 2.1 to 2.10 which include laying the foundations and planning multi-disciplinary research teams that include professional researchers, students and young people as Youth Citizen Scientists (YCS), recruiting and engaging YCS, students and stakeholders, developing and refining research methods to explore social inclusion with YCS and conducting co-creative research with young people. The primary focus is on case experiences with implementing the social inclusion sub study. It therefore provides details of the 10 local cases in nine countries in a multiple case study of co-creative Y-CSS in Europe and their experiences.  The cross case thematic analysis builds on the individual case reports, extracts from the evaluation self-reports and notes from consortium or WP2 discussions. 

This Report comprises six parts: (1) background and contextual overview of YouCount’s aims and intentions in implementing the multiple case study of hands-on Y-CSS; (2) planning and establishing Y-CSS; (3) recruitment, training and support of YCS; (4) methodologies adopted by the local cases including the designs, methods and data analysis conducted; (5) what co-creation meant in practice; (6) summary and conclusions. 

The main target groups for this Deliverable are those interested in how Y-CSS can be conducted in practice, either as practitioner, scientists or evaluator of best practices.

 

This version 3 is the same as version 1 & 2, but included names of internal scientific reviewers and changed layout p 27.

description: Models of active galactic nuclei (AGN) suggest that their circumnuclear media are complex with clumps and filaments, while recent observations hint towards polar extended structures of gas and dust, as opposed to the classical torus paradigm. The X-ray band forms an interesting window to study these circumnuclear media in great detail. In this work, we extended the radiative transfer code SKIRT with the X-ray processes that govern the broadband X-ray spectra of obscured AGN, to study the structure of AGN circumnuclear media in full 3D, based on their reflected X-ray emission. We extended the SKIRT code with Compton scattering on free electrons, photo-absorption and fluorescence by cold atomic gas, scattering on bound electrons, and extinction by dust. This includes a novel treatment of extreme-forward scattering by dust, and a detailed description of anomalous Rayleigh scattering. To verify our X-ray implementation, we performed the first dedicated benchmark of X-ray torus models, comparing five X-ray radiative transfer codes. Finally, we illustrated the 3D nature of the code by producing synthetic X-ray images and spectra of clumpy torus models. SKIRT forms a powerful new tool to model AGN circumnuclear media in full 3D from X-ray to millimetre wavelengths, and is now publicly available. In the X-ray regime, we find an excellent agreement with the simulation results of the MYTorus and RefleX codes, which validates our X-ray implementation. We find some discrepancies with other codes, which motivates the need for a robust framework that can handle non-linear 3D radiative transfer effects. The new X-ray functionalities of the SKIRT code allow for uncomplicated access to a broad suite of 3D X-ray models for AGN that can easily be tested and modified. This will be particularly useful with the advent of X-ray microcalorimeter observations.

description: We use the calibrations by Calamida et al. and by Hilker et al., and the standardised synthetic photometry in the v, b, and y Stromgren passbands from Gaia DR3 BP/RP spectra, to obtain photometric metallicities for a selected sample of 694233 old Galactic giant stars having |b|>20.0 and parallax uncertainties lower than 10%. The zero point of both sets of photometric metallicities has been shifted to to ensure optimal match with the spectroscopic [Fe/H] values for 44785 stars in common with APOGEE DR17, focusing on the metallicity range where they provide the highest accuracy. The metallicities derived in this way from the Calamida et al. calibration display a typical accuracy of ~0.1 dex and 1 sigma precision ~0.2 dex in the range -2.2 <=[Fe/H]<= -0.4, while they show a systematic trend with [Fe/H] at higher metallicity, beyond the applicability range of the relation. Those derived from the Hilker et al. calibration display, in general, worse precision, and lower accuracy in the metal-poor regime, but have a median accuracy < 0.05 dex for [Fe/H]>= -0.8. These results are confirmed and, consequently, the metallicities validated, by comparison with large sets of spectroscopic metallicities from various surveys. The newly obtained metallicities are used to derive metallicity distributions for several previously identified sub-structures in the Galactic halo with an unprecedented number of stars. The catalogue including both sets of metallicities and the associated uncertainties is made publicly available.

description: Visual-audio navigation (VAN) is attracting more and more attention from the robotic community due to its broad applications, \emph{e.g.}, household robots and rescue robots. In this task, an embodied agent must search for and navigate to the sound source with egocentric visual and audio observations. However, the existing methods are limited in two aspects: 1) poor generalization to unheard sound categories; 2) sample inefficient in training. Focusing on these two problems, we propose a brain-inspired plug-and-play method to learn a semantic-agnostic and spatial-aware representation for generalizable visual-audio navigation. We meticulously design two auxiliary tasks for respectively accelerating learning representations with the above-desired characteristics. With these two auxiliary tasks, the agent learns a spatially-correlated representation of visual and audio inputs that can be applied to work on environments with novel sounds and maps. Experiment results on realistic 3D scenes (Replica and Matterport3D) demonstrate that our method achieves better generalization performance when zero-shot transferred to scenes with unseen maps and unheard sound categories.

description: We have used asteroseismology to determine fundamental properties for 66 Kepler planet-candidate host stars, with typical uncertainties of 3% and 7% in radius and mass, respectively. The results include new asteroseismic solutions for four host stars with confirmed planets (Kepler-4, Kepler-14, Kepler-23 and Kepler-25) and increase the total number of Kepler host stars with asteroseismic solutions to 77. A comparison with stellar properties in the planet-candidate catalog by Batalha et al. shows that radii for subgiants and giants obtained from spectroscopic follow-up are systematically too low by up to a factor of 1.5, while the properties for unevolved stars are in good agreement. We furthermore apply asteroseismology to confirm that a large majority of cool main-sequence hosts are indeed dwarfs and not misclassified giants. Using the revised stellar properties, we recalculate the radii for 107 planet candidates in our sample, and comment on candidates for which the radii change from a previously giant-planet/brown-dwarf/stellar regime to a sub-Jupiter size, or vice versa. A comparison of stellar densities from asteroseismology with densities derived from transit models in Batalha et al. assuming circular orbits shows significant disagreement for more than half of the sample due to systematics in the modeled impact parameters, or due to planet candidates which may be in eccentric orbits. Finally, we investigate tentative correlations between host-star masses and planet candidate radii, orbital periods, and multiplicity, but caution that these results may be influenced by the small sample size and detection biases.

Subjects: augmented reality, music technology, sonic art, installation, instrumentality

description: This research proposal develops multi-sensory AR technology as a novel method to address the current visual bias in AR development, through the question: What impact do multi-sensory AR experiences have on human perception and expression in participatory installation art? I outline contemporary literature that discusses the possibility for multi-sensory AR, as well as examples of installations that utilise non-visual modes of perceptual mediation. I will use an iterative design process to create my own multi- sensory AR instruments, which will be used in an installation. Through individual and group studies of the instrument and installation respectively, I aim to answer the question through a combination of rigorous survey-based quantitative data analysis, as well as a grounded theory approach to qualitatively analyse interview feedback. The findings would culminate in a thesis paper exploring the impact of augmented reality technology on user perception and expression, and the creation of a software tool that could be used as a research platform and framework for creating multi- sensory AR experiences that are immersive for both artist and audience.

We prove that the orbit of the origin under this map coincides with a low discrepancy sequence (which we call Kakutani-Fibonacci sequence of points), which has been also considered by other authors.

description: Building on the generalization of the exactly dimerized Majumdar-Ghosh ground state to arbitrary spin S for the Heisenberg chain with a three-site term (S_{i-1} S_i)(S_i S_{i+1}) + H.c., we use density-matrix renormalization group simulations and exact diagonalizations to determine the nature of the dimerization transition for S=1, 3/2 and 2. The resulting central charge and critical exponent are in good agreement with the SU(2)_{k=2S} Wess-Zumino-Witten values c=3k/(2+k) and η=3/(2+k). Since the 3-site term that induces dimerization appears naturally if exchange interactions are calculated beyond second order, these results suggest that SU(2)_{k>1} Wess-Zumino-Witten models might finally be realized in actual spin chains.

description: Incorporating deep learning (DL) classification models into unmanned aerial vehicles (UAVs) can significantly augment search-and-rescue operations and disaster management efforts. In such critical situations, the UAV's ability to promptly comprehend the crisis and optimally utilize its limited power and processing resources to narrow down search areas is crucial. Therefore, developing an efficient and lightweight method for scene classification is of utmost importance. However, current approaches tend to prioritize accuracy on benchmark datasets at the expense of computational efficiency. To address this shortcoming, we introduce the Wider ATTENTION EfficientNet (WATT-EffNet), a novel method that achieves higher accuracy with a more lightweight architecture compared to the baseline EfficientNet. The WATT-EffNet leverages width-wise incremental feature modules and attention mechanisms over width-wise features to ensure the network structure remains lightweight. We evaluate our method on a UAV-based aerial disaster image classification dataset and demonstrate that it outperforms the baseline by up to 15 times in terms of classification accuracy and 38.3% in terms of computing efficiency as measured by Floating Point Operations per second (FLOPs). Additionally, we conduct an ablation study to investigate the effect of varying the width of WATT-EffNet on accuracy and computational efficiency. Our code is available at \url{https://github.com/TanmDL/WATT-EffNet}.

description: A total of 62 isolates of Riemerella-like organisms, originally isolated from Australian poultry (10 from chickens, 46 from ducks, five from unknown hosts and one vaccine strain), were included in this study. On the basis of two published polymerase chain reaction (PCR) assays that are reported to be specific for Riemerella anatipestifer, 51 of the isolates were identified as R. anatipestifer. Forty-six of these isolates had a detailed history and were sourced from ducks, while five were of unknown origin. The 11 remaining isolates failed to yield a positive reaction in either PCR with 10 originating from chickens and one from a duck. Amplification and sequencing of the 16S rRNA gene of these isolates identified the duck isolate as Moraxella lacunta. Phylogenetic analysis of the 10 chicken isolates identified one as R. columbina and the remaining nine isolates as Riemerella-like taxon 2. The 51 Australian R. anatipestifer isolates were assigned by gel diffusion test to serovars 1 (26 isolates), 6 (seven isolates), 8 (five isolates), 9 (two isolates), 13 (one isolate) and 14 (one isolate) while nine isolates gave no reaction to any antiserum. A commercial system was used to perform DNA fingerprinting using rep-PCR analysis, which revealed different clusters with a lack of a clear relationship between the clusters and the serovars.

Συνέπεια των ανωτέρω είναι ο μονόδρομος για ανάπτυξη ενός ευέλικτου λογισμικού για το πρόβλημα δρομολόγησης οχημάτων με χρονικά παράθυρα (Vehicle Routing Problem with Time Windows - VRPTW), με έμφαση στην  ακρίβεια και την ταχύτητα εκτελέσεως. Σύγχρονες γλώσσες προγραμματισμού όπως η Java καθιστούν την προσπάθεια αυτή ακόμα πιο ανταγωνιστική. Στην εργασία ευρέθη μια καινοτόμος αλγοριθμική μεθοδολογία ονόματι « Αναζήτηση μεταφορών με άπληστη αρχικοποιημένη δρομολόγηση – Greedy Initialized Routing Search On Transportations (GIRSOT) ». Η εργασία απαρτίζεται από πέντε κεφάλαια με τη λογική το «διαίρει και βασίλευε» επιχειρείται η λύσις του προβλήματος υπό τη λύση πολλών μικρότερων προβλημάτων, έτσι στο πρώτο κεφάλαιο γίνεται  παρουσίαση του προβλήματος, στο δεύτερο προτείνεται ένας καλός αλγόριθμος ομαδοποίησης των πελατών (3-PCC).  Στο τρίτο κεφάλαιο γίνεται μια προσπάθεια κατασκευής μιας μεθόδου βελτιστοποίησης επί των δρομολογίων. Το αποτέλεσμα που προκύπτει δεν είναι ούτε απογοητευτικό αλλά και ούτε αρκετό. Στο τέταρτο κεφάλαιο προτείνεται ένας ακόμα αλγόριθμος, ο αλγόριθμος σποράς (seeding algorithm) ο οποίος δίνει στον αλγόριθμο GIRSOT την πολυεναρκτήρια ιδιότητα του. Επόμενο βήμα θα είναι μια ύστατη προσπάθεια μείωσης ακόμα περισσότερο του κόστους, με τη μέθοδο μαζικής ανάθεσης  - group relocate. Αν όλες οι ανωτέρω διαδικασίες αποτύχουν εφαρμόζεται η χρονική υποτίμησiς (Devaluation Time Algorithm – BTA), η οποία εξαναγκάζει τη 3-PCC να δώσει νέες αρχικές λύσεις με περισσότερα οχήματα. Τέλος στο κεφάλαιο πέντε επιλέγεται το δείγμα απ’ τα προβλήματα του Solomon n100 και των Gehring & Homberger’s  για να δειχθεί η αποτελεσματικότητα του  προτεινόμενου αλγορίθμου.

description: Aims: We study the influence of rotation and disc lifetime on lithium depletion of pre-main sequence (PMS) solar-type stars. Methods: The impact of rotational mixing and of the hydrostatic effects of rotation on lithium abundances are investigated by computing non-rotating and rotating PMS models that include a comprehensive treatment of shellular rotation. The influence of the disc lifetime is then studied by comparing the lithium content of PMS rotating models experiencing different durations of the disc-locking phase between 3 and 9 Myr. Results: The surface lithium abundance at the end of the PMS is decreased when rotational effects are included. During the beginning of the lithium depletion phase, only hydrostatic effects of rotation are at work. This results in a decrease in the lithium depletion rate for rotating models compared to non-rotating ones. When the convective envelope recedes from the stellar centre, rotational mixing begins to play an important role due to differential rotation near the bottom of the convective envelope. This mixing results in a decrease in the surface lithium abundance with a limited contribution from hydrostatic effects of rotation, which favours lithium depletion during the second part of the PMS evolution. The impact of rotation on PMS lithium depletion is also found to be sensitive to the duration of the disc-locking phase. When the disc lifetime increases, the PMS lithium abundance of a solar-type star decreases owing to the higher efficiency of rotational mixing in the radiative zone. A relationship between the surface rotation and lithium abundance at the end of the PMS is then obtained: slow rotators on the zero-age main sequence are predicted to be more lithium-depleted than fast rotators due to the increase in the disc lifetime.

description: We analyse spectroscopic and photometric transits of the hot Jupiters WASP-52b and HAT-P30b obtained with ESPRESSO, Eulercam and NGTS for both targets, and additional TESS data for HAT-P-30. Our goal is to update the system parameters and refine our knowledge of the host star surfaces. For WASP-52, the companion planet has occulted starspots in the past, and as such our aim was to use the reloaded Rossiter-McLaughlin technique to directly probe its starspot properties. Unfortunately, we find no evidence for starspot occultations in the datasets herein. Additionally, we searched for stellar surface differential rotation (DR) and any centre-to-limb variation (CLV) due to convection, but return a null detection of both. This is unsurprising for WASP-52, given its relatively cool temperature, high magnetic activity (which leads to lower CLV), and projected obliquity near 0 degrees (meaning the transit chord is less likely to cross several stellar latitudes). For HAT-P-30, this result was more surprising given its hotter effective temperature, lower magnetic field, and high projected obliquity (near 70 degrees). To explore the reasons behind the null DR and CLV detection for HAT-P-30, we simulated a variety of scenarios. We find that either the CLV present on HAT-P-30 is below the solar level or the presence of DR prevents a CLV detection given the precision of the data herein. A careful treatment of both DR and CLV is required, especially for systems with high impact factors, due to potential degeneracies between the two. Future observations and/or a sophisticated treatment of the red noise present in the data (likely due to granulation) is required to refine the DR and CLV for these particular systems; such observations would also present another opportunity to try to examine starspots on WASP-52.

The simplified physics model is described and simulated using simple constant angular velocity equation. Four computer model design ideas such as 1) simple and realistic 3D view and associated learning to real world, 2) comparative visualization of permanent geostationary satellite 3) examples of non-geostationary orbits of different 3-1) rotation sense, 3-2) periods, 3-3) planes and 4) incorrect physics model for conceptual discourse are discussed. General feedback from the students has been relatively positive, and we hope teachers will find the computer model useful in their own classes. 2015 Resources http://iwant2study.org/ospsg/index.php/interactive-resources/physics/02-newtonian-mechanics/08-gravity/62-gravity10

description: Fast and accurate MRI reconstruction is a key concern in modern clinical practice. Recently, numerous Deep-Learning methods have been proposed for MRI reconstruction, however, they usually fail to reconstruct sharp details from the subsampled k-space data. To solve this problem, we propose a lightweight and accurate Edge Attention MRI Reconstruction Network (EAMRI) to reconstruct images with edge guidance. Specifically, we design an efficient Edge Prediction Network to directly predict accurate edges from the blurred image. Meanwhile, we propose a novel Edge Attention Module (EAM) to guide the image reconstruction utilizing the extracted edge priors, as inspired by the popular self-attention mechanism. EAM first projects the input image and edges into Q_image, K_edge, and V_image, respectively. Then EAM pairs the Q_image with K_edge along the channel dimension, such that 1) it can search globally for the high-frequency image features that are activated by the edge priors; 2) the overall computation burdens are largely reduced compared with the traditional spatial-wise attention. With the help of EAM, the predicted edge priors can effectively guide the model to reconstruct high-quality MR images with accurate edges. Extensive experiments show that our proposed EAMRI outperforms other methods with fewer parameters and can recover more accurate edges.

description: We use lattice simulations and the continuous renormalization-group method, based on the gradient flow, to study a candidate theory of composite Higgs and a partially composite top. The model is an SU(4) gauge theory with four Dirac fermions in each of the fundamental and two-index antisymmetric representations. We find that the theory has an infrared fixed point at $g^2 \simeq 15.5$ in the gradient flow scheme. The mass anomalous dimension of each representation is large at the fixed point. On the other hand, the anomalous dimensions of top-partner operators do not exceed 0.5 at the fixed point. This may not be large enough for a phenomenologically successful model of partial compositeness.

description: Infectious bursal disease (IBD), caused by IBD virus (IBDV), is highly contagious, immunosuppressive and causes a negative economic impact on poultry industry. IBDV-vaccinated broiler farms at south Kyushu, Japan had a bursa-to-bodyweight ratio (BB ratio) reduction at 28 days (d) old, followed by high mortality 30 d later. We analysed the influence of the IBDV on atrophy of the bursa of fabricius (BF) and the subsequent mortality after 30 d. Ten broilers were sampled at each timepoint from the farm with high mortality at 21, 25, 28 and 35 d. A second flock from the same farm was sampled at 14, 21, 25, 28, 35 and 42 d. IBDV was detected in BF samples at 25, 28 and 35 d and at 21, 25, 28 and 35 d in the first and second flocks, respectively, using immunohistochemical staining and RT-PCR. IBDV isolates from both flocks were closely related to the China KM523643 strain. Histopathology and TUNEL assay indicated apoptosis, severe lymphoid depletion, vacuoles within follicles, lymphoid follicle atrophy and fibrosis in the BF. We observed 75% of the polyserositis and 10% of the airsacculitis at 30 D in dead broilers. The antigenic variant IBDV infection was appeared to be the main influencing factor on BF atrophy and BB ratio reduction in the broilers. High mortality in the broilers after 30 d could be due to secondary infection. The disease caused by IBDV had a negative economic impact in the farm. RESEARCH HIGHLIGHTSNew variant IBDV caused bursa atrophy and reduced BB ratio in 28-day-old broilers.After vIBDV had infected broilers, at 21 days old they became immunosuppressed.High mortality at 30 days old in broilers was due to secondary infection.New vIBDV has a negative economic impact on broiler farms in Japan.
