description: This study explores the digital and social media information habits and preferences of students, particularly as they concern issues-based communication relating to climate change and sustainability. Researchers surveyed 203 undergraduate students studying a wide range of subject areas in a small Canadian liberal arts style university. Results were analysed using basic statistics to determine broad trends in social and digital media use among participants, their assessment of what kinds of content they found engaging online and their preferences relating to searching and sharing information on news and issues. Different environmental messages were also assessed by participants for whether they were engaging. Participants used a wide variety of platforms, in diverse locations, but demonstrated a tendency to use Google and YouTube most often to search for issues about which they cared. Respondents indicated a preference for image or video-based content, and also indicated that images and videos made a website more attractive. They generally reported not sharing news on social media, and tended to rate environmental messages with a problem-solution framework as most engaging. This study suggests that climate-change related issue marketing should favour YouTube and other video content, and should pay close attention to how environmental messages are presented in order to be most engaging to their target audiences.

description: We review our recent work on the formation and evolution of disks with in triaxial dark matter (DM) halos by means of numerical simulations, including star formation and feedback from stellar evolution. The growing disks are strongly in fluenced by shapes of DM halos and modify them in turn. Disk parameters are in a broad agreement with those in the local universe. Gas-rich stellar bars grow in tandem with the disk and facilitate the angular momentum redistribution in the system and radial gas inflow. Nested bars appear to form as a by-product. Interactions between various non-axisymmetric components -- bars, disks and halos lead to decay of bars or washing out of ellipticity in the inner halo.

description: Continual learning aims to provide intelligent agents capable of learning multiple tasks sequentially with neural networks. One of its main challenging, catastrophic forgetting, is caused by the neural networks non-optimal ability to learn in non-stationary distributions. In most settings of the current approaches, the agent starts from randomly initialized parameters and is optimized to master the current task regardless of the usefulness of the learned representation for future tasks. Moreover, each of the future tasks uses all the previously learned knowledge although parts of this knowledge might not be helpful for its learning. These cause interference among tasks, especially when the data of previous tasks is not accessible. In this paper, we propose a new method, named Self-Attention Meta-Learner (SAM), which learns a prior knowledge for continual learning that permits learning a sequence of tasks, while avoiding catastrophic forgetting. SAM incorporates an attention mechanism that learns to select the particular relevant representation for each future task. Each task builds a specific representation branch on top of the selected knowledge, avoiding the interference between tasks. We evaluate the proposed method on the Split CIFAR-10/100 and Split MNIST benchmarks in the task agnostic inference. We empirically show that we can achieve a better performance than several state-of-the-art methods for continual learning by building on the top of selected representation learned by SAM. We also show the role of the meta-attention mechanism in boosting informative features corresponding to the input data and identifying the correct target in the task agnostic inference. Finally, we demonstrate that popular existing continual learning methods gain a performance boost when they adopt SAM as a starting point.

description: This paper will deal with the modeling-problem of combining thermal subsystems (e.g. a semiconductor module or package with a cooling radiator) making use of reduced models. The subsystem models consist of a set of Foster-type thermal equivalent circuits, which are only behavioral models. A fast al-gorithm is presented for transforming the Foster-type circuits in Cauer-circuits which have physical behavior and therefore allow for the construction of the thermal model of the complete system. Then the set of Cauer-circuits for the complete system is transformed back into Foster-circuits to give a simple mathematical representation and applicability. The transfor-mation algorithms are derived in concise form by use of recur-sive relations. The method is exemplified by modeling and measurements on a single chip IGBT package mounted on a closed water cooled radiator. The thermal impedance of the complete system is constructed from the impedances of the sub-systems, IGBT-package and radiator, and also the impedance of the package can be inferred from the measured impedance of the complete system.

description: In axial gauge, the (2+1)-dimensional SU($N$) Yang-Mills theory is equivalent to a set of (1+1)-dimensional integrable models with a non-local coupling between charge densities. This fact makes it possible to determine the static potential between charges at weak coupling in an anisotropic version of the theory, and understand features of the spectrum.

The Potential-Density Phase Shift Method for Determining the Corotation Radii in Spiral and Barred Galaxies
Creators: name: Zhang, Xiaolei

Publisher: name: arXiv
Year: 2006
Subjects: subject: Astrophysics (astro-ph)

description: We have developed a new method for determining the corotation radii of density waves in disk galaxies, which makes use of the radial distribution of an azimuthal phase shift between the potential and density wave patterns. The approach originated from improved theoretical understandings of the relation between the morphology and kinematics of galaxies, and on the dynamical interaction between density waves and the basic-state disk stars which results in the secular evolution of disk galaxies. In this paper, we present the rationales behind the method, and the first application of it to several representative barred and grand-design spiral galaxies, using near-infrared images to trace the mass distributions, as well as to calculate the potential distributions used in the phase shift calculations. We compare our results with those from other existing methods for locating the corotations, and show that the new method both confirms the previously-established trends of bar-length dependence on galaxy morphological types, as well as provides new insights into the possible extent of bars in disk galaxies. Application of the method to a larger sample and the preliminary analysis of which show that the phase shift method is likely to be a generally-applicable, accurate, and essentially model-independent method for determining the pattern speeds and corotation radii of single or nested density wave patterns in galaxies. Other implications of this work are: most of the nearby bright disk galaxies appear to possess quasi-stationary spiral modes; that these density wave modes and the associated basic state of the galactic disk slowly transform over time; and that self-consistent N-particle systems contain physics not revealed by the passive orbit analysis approaches.

description: 3D pedestrian detection is a challenging task in automated driving because pedestrians are relatively small, frequently occluded and easily confused with narrow vertical objects. LiDAR and camera are two commonly used sensor modalities for this task, which should provide complementary information. Unexpectedly, LiDAR-only detection methods tend to outperform multisensor fusion methods in public benchmarks. Recently, PointPainting has been presented to eliminate this performance drop by effectively fusing the output of a semantic segmentation network instead of the raw image information. In this paper, we propose a generalization of PointPainting to be able to apply fusion at different levels. After the semantic augmentation of the point cloud, we encode raw point data in pillars to get geometric features and semantic point data in voxels to get semantic features and fuse them in an effective way. Experimental results on the KITTI test set show that SemanticVoxels achieves state-of-the-art performance in both 3D and bird's eye view pedestrian detection benchmarks. In particular, our approach demonstrates its strength in detecting challenging pedestrian cases and outperforms current state-of-the-art approaches.

Cartographing dynamic stall with machine learning

description: Once stall has set in, lift collapses, drag increases and then both of these forces will fluctuate strongly. The result is higher fatigue loads and lower energy yield. In dynamic stall, separation first develops from the trailing edge up the leading edge. Eventually the shear layer rolls up, and then a coherent vortex forms and then sheds downstream with its low-pressure core causing a lift overshoot and moment drop. When 50+ experimental cycles of lift or pressure values are averaged, this process appears clear and coherent in flow visualizations. Unfortunately, stall is not one clean process but a broad collection of processes. This means that the analysis of separated flows should be able to detect outliers and analyze cycle-to-cycle variations. Modern data science and machine learning can be used to treat separated flows. In this study, a clustering method based on dynamic time warping is used to find different shedding behaviors. This method captures the fact that secondary and tertiary vorticity vary strongly, and in static stall with surging flow the flow can occasionally reattach. A convolutional neural network was used to extract dynamic stall vorticity convection speeds and phases from pressure data. Finally, bootstrapping was used to provide best practices regarding the number of experimental repetitions required to ensure experimental convergence.

description: Two-dimensional ferromagnetic N-state clock models are studied on a hyperbolic lattice represented by tessellation of pentagons. The lattice lies on the hyperbolic plane with a constant negative scalar curvature. We observe the spontaneous magnetization, the internal energy, and the specific heat at the center of sufficiently large systems, where the fixed boundary conditions are imposed, for the cases N>=3 up to N=30. The model with N=3, which is equivalent to the 3-state Potts model on the hyperbolic lattice, exhibits the first order phase transition. A mean-field like phase transition of the second order is observed for the cases N>=4. When N>=5 we observe the Schottky type specific heat below the transition temperature, where its peak hight at low temperatures scales as N^{-2}. From these facts we conclude that the phase transition of classical XY-model deep inside the hyperbolic lattices is not of the Berezinskii-Kosterlitz-Thouless type.

We make the Migdal/5D relation more precise by quantifying the correspondence between Pade approximation and the background and boundary conditions in 5D. We also establish a connection between the Migdal approach and the models of deconstructed dimensions.

Στην έρευνα συμμετείχαν 101 ενήλικες έλληνες που ασχολούνται με την χιονοδρομία και 102 που ασχολούνται με την χιονοσανίδα αναψυχής. Για τη μέτρηση των ανασταλτικών παραγόντων χρησιμοποιήθηκε στα μέτρα της έρευνας η κλίμακα των Alexandris και Carroll (1997). Τα δεδομένα αναλύθηκαν με τη χρήση του στατιστικού πακέτου SPSS for Windows (13.0). Πραγματοποιήθηκε περιγραφική στατιστική ανάλυση, ανάλυση αξιοπιστίας, αναλύσεις διακύμανσης με ένα παράγοντα (one- way ANOVA) και t-test. Οι διαστάσεις των ανασταλτικών παραγόντων που εξετάστηκαν ήταν έξι : έλλειψη χρόνου, ψυχολογικά εμπόδια, έλλειψη ενδιαφέροντος για συμμετοχή, προτεραιότητα, προβλήματα οικονομικά/καιρού και έλλειψη παρέας. Τα αποτελέσματα από τη στατιστική ανάλυση έδειξαν ότι ο παράγοντας που βιώνεται με μεγαλύτερη ένταση είναι η «έλλειψη ενδιαφέροντος» και γενικά οι ενδοπροσωπικοί παράγοντες, ότι οι snowboarders έχουν χαμηλότερη αντίληψη για τους ανασταλτικούς παράγοντες από τους skier και προέκυψαν σημαντικές διαφορές από την σύγκριση των δημογραφικών χαρακτηριστικών των δύο ομάδων. Τα αποτελέσματα υποστηρίζουν ότι οι διοικήσεις των χιονοδρομικών κέντρων θα πρέπει να γνωρίζουν το προφίλ των επισκεπτών τους και τους ανασταλτικούς παράγοντες ώστε να ακολουθείται αντίστοιχη διοίκηση και οργάνωση των κέντρων.
description: The aim of this study was to investigate and compare constraints on recreational skiing and snowboarding, to compare demographic characteristics and to find possible differences in perception of constraints among different demographic groups. One hundred and one Greek adults skiers and one hundred and two snowboarders participated in the study. The leisure constraints questionnaire (Alexandris & Carroll, 1997) was used to measure constraints. The data were analyzed with SPSS. Descriptive statistics, reliability analysis, ANOVA’s and t-tests were used for statistical analysis. Six constraint dimensions were examined, based on the literature: individual / psychological, lack of interest, lack of partners, priority, financial / weather, lack of time. The results indicated that the «lack of interest» were the most important constraint, that the snowboarders were less constrained than the skiers and there were significant differences in the compare of demographic factors between the two groups. The results propose that administrations of ski resorts should know constraints and demographic characteristics of their visitors and to organize and manage the resorts according to the demands and needs of their clients.

description: Recent experiments with strong THz fields in both conventional and unconventional superconductors have clearly evidenced a marked third-harmonic generation below the superconducting temperature $T_c$. Its interpretation challenged substantial theoretical work aimed at establishing the relative efficiency of quasiparticle excitations and collective modes in triggering such a resonant response. Here we compute the non-linear current by implementing a time-dependent Bogoljubov de-Gennes approach, with the twofold aim to account non-perturbatively for the effect of local disorder, and to include the contribution of all collective modes, i.e. superconducting amplitude (Higgs) and phase fluctuations, and charge fluctuations. We show that, in agreement with previous work, already at small disorder the quasiparticle response is dominated by paramagnetic effects. We further demonstrate that paramagnetic processes mediate also the response of all collective modes, with a substantial contribution of charge/phase fluctuations. These processes, which have been overlooked so far, turn out to dominate the third-order current at strong disorder. In addition, we show that disorder strongly influences the polarization dependence of the non-linear response, with a marked difference between the clean and the disordered case. Our results are particularly relevant for recent experiments in cuprates, whose band structure is in a first approximation reproduced by our lattice model.

description: In this geographic analysis, the basic point is what is the degree of the development’s inequalities from all the municipal districts of a county. This measurement of the degree shows any needfull, understanding information for the and its dynamic at the social and economic parts. First, in this project can been seen the geographic dimension of the development and the basic point is the local one (development), and the reason is the local production with the usage of local pores and with the help of the guidance and check of the local community for the local consumption, it is the only secure and feasible solution in nowdays, which is obvious that is against the development of local production. It can be seen also from the basic theories of the unequal local development and the sequiturs of its application, shows what are the needs and the developing directions. Also in this project can been seen the information for the inequalities in European area and the efforts of the European communities which try to fight off against the future stipulated tensions. The results of the developing diastasis and the process of development of municipal districts of the county, can been seen at the analysis and the process of the statistic data. The bases of this analysis are population, education, occupation, economy and the foundations. Those bases have been chosen because this is the best way of understanding the developing diastasis of the county, also for any base , there are the separate index which shows the developing inequalities. Finally, in this project can been seen also how the most important developing local centers, depend from the development pole of the county. That means that there is an obvious image of their geographic diastasis, also what are the most important points which show how the development of the county to be well-balanced.

description: Vinpocetine (Vin), a synthetic-derivative of Vincamine, monoterpenoid indole alkaloid, has been reported to have various medicinal benefits. The purpose of our study was to investigate the pivotal role of “nuclear factor erythroid 2-related factor-2” (Nrf2)-mediated antioxidant protection of Vin against H2O2 and paracetamol (APAP)-induced liver toxicity. For this purpose, a normal human hepatic cell line (L02 cells) was incubated with cytotoxic concentrations of H2O2 or APAP in the presence or absence of Vin. To evaluate the responses, MTS Cell Viability assay, immunoblotting, biochemical assays, and molecular docking approach were used. Viability analysis showed that treatment of L02 cells with Vin prevented the cytotoxicity induced by H2O2 and APAP. It was evidenced by the fact that Vin dumped H2O2- and APAP-cytotoxicity and reactive oxygen species (ROS) generation. The immuno¬blotting analysis shows that Vin increased Nrf2 expression along with the expression of target protein, heme oxygenase-1 (HO-1), and increased intracellular glutathione (GSH) level. Interestingly, we found that Vin could protect the protein expression-level of Nrf2, which indicated the prospective interaction between Vin and Keap1 protein. Additionally, molecular docking-study revealed that Vin competed with Nrf2 for Keap1-binding site, with hydrogen and stearic interactions. Collectively, Vin effectively protects against H2O2 and APAP-induced cytotoxicity via executing Nrf2-mediated restoration of antioxidative/oxidative balance. Meanwhile, Vin interrupts protein-protein interaction between Nrf2 and Keap1, which might also contribute to decrease Nrf2 degradation and stabilize protein expression. Thus, Vin-based adjuvant therapy may represent a smart drug regimen to mitigate drug-induced oxidative stress and liver injuries.

description: Aims. We aim to determine whether dissociative excitation of cometary neutrals by electron impact is the major source of far-ultraviolet (FUV) emissions at comet 67P/Churyumov-Gerasimenko in the southern hemisphere at large heliocentric distances, both during quiet conditions and impacts of corotating interaction regions observed in the summer of 2016. Methods. We combined multiple datasets from the Rosetta mission through a multi-instrument analysis to complete the first forward modelling of FUV emissions in the southern hemisphere of comet 67P and compared modelled brightnesses to observations with the Alice FUV imaging spectrograph. We modelled the brightness of OI1356, OI1304, Lyman-$β$, CI1657, and CII1335 emissions, which are associated with the dissociation products of the four major neutral species in the coma: CO$_2$, H$_2$O, CO, and O$_2$. The suprathermal electron population was probed by RPC/IES and the neutral column density was constrained by several instruments: ROSINA, MIRO and VIRTIS. Results. The modelled and observed brightnesses of the FUV emission lines agree closely when viewing nadir and dissociative excitation by electron impact is shown to be the dominant source of emissions away from perihelion. The CII1335 emissions are shown to be consistent with the volume mixing ratio of CO derived from ROSINA. When viewing the limb during the impacts of corotating interaction regions, the model reproduces brightnesses of OI1356 and CI1657 well, but resonance scattering in the extended coma may contribute significantly to the observed Lyman-$β$ and OI1304 emissions. The correlation between variations in the suprathermal electron flux and the observed FUV line brightnesses when viewing the comet's limb suggests electrons are accelerated on large scales and that they originate in the solar wind. This means that the FUV emissions are auroral in nature.

By a self-contained method of analysis, for the underdoped ($x=0.36$) sample, which harbors a magnetically-ordered tetragonal phase, we find it hosts a short nematic correlation length $ξ$ ~ 10 $Å$ and a large nematic susceptibility $χ_{\rm nem}$. The optimal-doped ($x=0.55$) sample exhibits weaker phonon softening effects, indicative of both reduced $ξ$ and $χ_{\rm nem}$. Our results suggest short-range nematic fluctuations may favor superconductivity, placing emphasis on the nematic correlation length for understanding the iron-based superconductors.

description: Thermal FEM (Finite Element Method) simulations can be used to predict the thermal behavior of power semiconductors in application. Most power semiconductors are made of silicon. Silicon thermal material properties are significantly temperature dependent. In this paper, validity of a common non-linear silicon material model is verified by transient non-linear thermal FEM simulations of Smart Power Switches and measurements. For verification, over-temperature protection behavior of Smart Power Switches is employed. This protection turns off the switch at a pre-defined temperature which is used as a temperature reference in the investigation. Power dissipation generated during a thermal overload event of two Smart Power devices is measured and used as an input stimulus to transient thermal FEM simulations. The duration time of the event together with the temperature reference is confronted with simulation results and thus the validity of the silicon model is proved. In addition, the impact of non-linear thermal properties of silicon on the thermal impedance of power semiconductors is shown.

description: We analyze HST and FUSE ultraviolet spectroscopic data for eleven sight lines passing through the infalling high velocity cloud (HVC) Complex C. These sight lines pass through regions with HI column densities ranging from N(HI) = 10^(18.1) to 10^(20.1). From [OI/HI] abundances, we find that Complex C metallicities range from 0.09 to 0.29 Z_solar, with a column density weighted mean of 0.13 Z_solar. Nitrogen (NI) is underabundant by factors of (0.01-0.07) (N/H)_solar, significantly less than oxygen relative to solar abundances. This pattern suggests nucleosynthetic enrichment by Type II SNe, consistent with an origin in the Galactic fountain or infalling gas produced in winds from Local Group galaxies. The range of metallicity and its possible (2 sigma) dependence on N(HI) could indicate some mixing of primordial material with enriched gas from the Milky Way, but the mixing mechanism is unclear. We also investigate the significant highly ionized component of Complex C, detected in CIV, SiIV, and OVI, but not in NV. High-ion column density ratios show little variance and are consistent with shock ionization or ionization at interfaces between Complex C and a hotter surrounding medium. Evidence for the former mechanism is seen in the Mrk 876 line profiles, where the offset in line centroids between low and high ions suggests a decelerating bowshock.

description: Антибиотики – это химические соединения биологического происхождения, оказывающие избирательное бактериоцитарное или бактериолитическое действие на микроорганизмы.  Их свойства были открыты в 1928 году английским бактериологом Александром Флемингом, который впервые выделил пенициллин в чистом виде из плесневого гриба.  Антибиотики, применяемые в медицинской практике, получают из актиномицетов (светящихся грибов), плесеней и некоторых бактерий.  Антибиотики спасли много жизней во время Второй мировой войны.  Несомненно, не будет преувеличением сказать, что открытие антибиотиков во многом способствовало продлению жизни человека.

description: Nanowire networks (NWNs) represent a unique hardware platform for neuromorphic information processing. In addition to exhibiting synapse-like resistive switching memory at their cross-point junctions, their self-assembly confers a neural network-like topology to their electrical circuitry, something that is impossible to achieve through conventional top-down fabrication approaches. In addition to their low power requirements, cost effectiveness and efficient interconnects, neuromorphic NWNs are also fault-tolerant and self-healing. These highly attractive properties can be largely attributed to their complex network connectivity, which enables a rich repertoire of adaptive nonlinear dynamics, including edge-of-chaos criticality. Here, we show how the adaptive dynamics intrinsic to neuromorphic NWNs can be harnessed to achieve transfer learning. We demonstrate this through simulations of a reservoir computing implementation in which NWNs perform the well-known benchmarking task of Mackey-Glass (MG) signal forecasting. First we show how NWNs can predict MG signals with arbitrary degrees of unpredictability (i.e. chaos). We then show that NWNs pre-exposed to a MG signal perform better in forecasting than NWNs without prior experience of an MG signal. This type of transfer learning is enabled by the network's collective memory of previous states. Overall, their adaptive signal processing capabilities make neuromorphic NWNs promising candidates for emerging real-time applications in IoT devices in particular, at the far edge.

description: The multifunctional support structure (MFSS) technology is promising a reduction of overall mass and packing volume for spacecraft (S/C) electronic components. This technology eliminates the electronic box chassis and the cabling between the boxes by integrating the electronics, thermal control and the structural support into one single element. The ultimate goal of the MFSS technology is to reduce size, weight, power consumption, cost and production time for future spacecraft components. The paper focus on the main challenges and solutions related to the thermal management within the MFSS technology based on the selected charge regulator (CR) application. Starting with the main set of thermal requirements for the CR the paper will include, conceptual and detailed design based on highconductivity carbon fibre CFRP, description and results of the thermal material sample test program ; parameter and results for the performed first thermal simulation

description: Οι ανοσολογικές αποκρίσεις είναι ιδιαίτερα πολύπλοκες και περιλαμβάνουν πλήθος διακριτών κυτταρικών και μοριακών διαδικασιών, αλλά λίγα είναι γνωστά για τις διαδικασίες αυτές στα δίθυρα μαλάκια. Η μελέτη του ανοσοποιητικού συστήματος των οργανισμών αυτών αφενός θα συμβάλλει στη καλύτερη κατανόηση των πολύπλοκων φαινομένων του ανοσοποιητικού συστήματος και αφετέρου θα εξασφαλίσει την καλύτερη διαχείριση των οργανισμών με μεγάλη οικονομική αξία. Στην παρούσα εργασία προσεγγίστηκε η μελέτη των αμυντικών μηχανισμών με την μελέτη της προσκόλλησης και της μετανάστευσης των αιμοκυττάρων του μυδιού Mytilus galloprovincialis σε πρωτεϊνικά υποστρώματα (λαμινίνη και κολλαγόνο τύπου IV) μετά την επίδραση καδμίου. Επιπρόσθετα, μελετήθηκε η συμμετοχή ορισμένων σηματοδοτικών μορίων σε αυτές τις διαδικασίες καθώς και ο ρόλος της α2 υπομονάδας των ιντεγκρινών. Tα αποτελέσματά μας, προτείνουν ότι το κάδμιο επάγει ένα σηματοδοτικό μονοπάτι, που συντελεί στην αύξηση του βαθμού προσκόλλησης και μετανάστευσης των αιμοκυττάρων του μυδιού Mytilus galloprovincialis καθώς και στην αύξηση της έκφρασης της α2β1 ιντεγκρίνης.

description: Immune responses are highly complex including a variety of different cellular and molecular processes, but little is known about these processes in mollusk bivalves. The study of the defense system in bivalves may lead to a better understanding of these highly complex phenomena and may allow more efficient control of those economically important organisms. In the present study we attempted to investigate the immune responses in Mytilus galloprovincialis by investigating the effects of cadmium on both adhesion and migration of haemocytes through protein substrates (laminin and collagen IV). In addition, it was of interest to elucidate the signaling molecules involved in these processes induced by cadmium as well as to investigate the role of α2 integrin subunit in haemocyte adhesion to collagen. Our results indicate that haemocytes exposed to cadmium attached to and migrate through protein substrates at a higher degree compared to control cells. In addition, our results show that cadmium causes a significant rise in α2β1 integrin expression. Moreover, our results suggest that ΝΗΕ, ΡΙ 3-Κ, PKC, NADPH oxidase, ΝΟ and ROS are involved in the signal transduction pathway induced by cadmium.
X-ray flares and the duration of engine activity in gamma-ray bursts

description: The detection of bright X-ray flares superimposed on the regular afterglow decay in Swift gamma-ray bursts has triggered theoretical speculations on their origin. We study the temporal properties of flares due to internal dissipation and external shock mechanisms. We first show that at least a sizable fraction of the flares cannot be related to external shock mechanisms, since external shock flares evolve on much longer time scales than observed. We then study flares from internal dissipation, showing that the temporal properties allow us to distinguish the emission of slow early shells from that of late faster shells. We show that, due to the rapid evolution of the detected flares, it is most likely that the flares are produced by relatively fast shells ejected by the central engine shortly before they are observed. This implies that the central engine must be active for, in some cases, as long as one day. We finally discuss the constraints and implications that this observation has on the properties and physics of the inner engine, and we elaborate on possible future observational tests on the flare sample to further understand their origin and physics.

description: Very low-mass Class I protostars have been investigated very little thus far. Variability of these young stellar objects (YSOs) and whether or not they are capable of strong episodic accretion is also left relatively unstudied. We investigate accretion variability in IRS54, a Class I very low-mass protostar with a mass of M$_{\star}$ ~ 0.1 - 0.2 M$_{\odot}$. We obtained spectroscopic and photometric data with VLT/ISAAC and VLT/SINFONI in the near-infrared ($J$, $H$, and $K$ bands) across four epochs (2005, 2010, 2013, and 2014). We used accretion-tracing lines (Pa$β$ and Br$γ$) and outflow-tracing lines (H$_2$ and [FeII] to examine physical properties and kinematics of the object. A large increase in luminosity was found between the 2005 and 2013 epochs of more than 1 magnitude in the $K$ band, followed in 2014 by a steep decrease. Consistently, the mass accretion rate ($\dot{M}_{acc}$) rose by an order of magnitude from ~ 10$^{-8}$ M$_{\odot}$ yr$^{-1}$ to ~ $10^{-7}$ M$_{\odot}$ yr$^{-1}$ between the two early epochs. The visual extinction ($A_V$) has also increased from ~ 15 mag in 2005 to ~ 24 mag in 2013. This rise in $A_V$ in tandem with the increase in $\dot{M}_{acc}$ is explained by the lifting up of a large amount of dust from the disc of IRS54, following the augmented accretion and ejection activity in the YSO, which intersects our line of sight due to the almost edge-on geometry of the disc. Because of the strength and timescales involved in this dramatic increase, this event is believed to have been an accretion burst possibly similar to bursts of EXor-type objects. IRS54 is the lowest mass Class I source observed to have an accretion burst of this type, and therefore potentially one of the lowest mass EXor-type objects known so far.
