Gesundheitliche Chancen und Risiken der Selbstoptimierung: Selbstoptimierung und psychische Gesundheit am Arbeitsplatz
Creators: name: Baumann, Pia
Publisher: name: Zenodo
Year: 2020

description: Das Betriebliche Gesundheitsmanagement und die Betriebliche Gesundheitsförderung machen es sich zum Ziel, nachhaltig Mitarbeitende darin zu unterstützen, sich in Richtung des Gesundheitspols zu bewegen oder ihren aktuellen Gesundheitszustand beizubehalten. Die Selbstoptimierung gesundheitlicher Aspekte durch das Individuum ist ein gesellschaftlicher Trend, welcher mitunter durch verfügbare technische Mittel unterstützt werden kann. Dies stellt das Betriebliche Gesundheitsmanagement sowie die Betriebliche Gesundheitsförderung vor die Frage, wie Selbstoptimierung zur Förderung von Gesundheit genutzt werden kann, ob weitere Aspekte beachtet werden müssen, oder ob Selbstoptimierung auch ein Potenzial hat, Gesundheit zu gefährden und wenn ja, unter welchen Bedingungen. Dies bedarf einer genauen Definition von Gesundheit und auch des Ziels insbesondere der Massnahmen der Betrieblichen Gesundheitsförderung. Selbstoptimierung als Stärkung und Anpassungsfähigkeit eines Individuums ist ein wirksames Mittel, welches unterstützt werden soll durch gesundheitsbezogene Massnahmen. Positive Konsequenzen wie das erhöhte Gefühl von Selbstwirksamkeit und im Falle von beispielsweise erhöhter Fitness sind nur ein paar Beispiele der Vorteile von Selbstoptimierung. Allerdings gilt es auch zu beachten, dass die Gesundheit von Mitarbeitenden zwar gefördert, nicht aber gefordert im Sinne von verlangt wird. Gehen mit der Selbstwirksamkeit ein Gefühl von Druck, Versagensängsten oder das Gefühl von Selbstbestimmung einher, so kann die Selbstoptimierung durchaus auch negative Wirkung haben. Somit wird empfohlen, dass die Bedingungen, unter denen Selbstoptimierung nahegelegt wird, reflektiert wird und weitere Forschung mehr Einsicht in dieses spannende und komplexe Thema gibt. So kann erst richtig ergründet werden, unter welchen Voraussetzungen und Bedingungen Selbstoptimierung als Mittel der (Betrieblichen) Gesundheitsförderung eingesetzt werden kann.

description: We report a polarized neutron diffraction study conducted to reveal the nature of the weak ferromagnetic moment in the superconducting ferromagnet UCoGe. We find that the ordered moment in the normal phase in low magnetic fields (B // c) is predominantly located at the U atom and has a magnitude of about 0.1 muB at 3 T, in agreement with bulk magnetization data. By increasing the magnetic field the U moment grows to about 0.3 muB in 12 T and most remarkably, induces a substantial moment (about 0.2 muB) on the Co atom directed antiparallel to the U moment. The anomalous polarizability of the Co 3d orbitals is unique among uranium intermetallics and might reflect the proximity to a magnetic quantum critical point of UCoGe in zero field.

The thermal ecology of populations and ecosystem services in a changing world
Creators: name: Bernhardt, Joanna Robin
Publisher: name: University of British Columbia
Year: 2018

description: A central goal of ecology is to understand what drives the abundance, distribution and diversity of life on Earth. For centuries, biologists have been addressing these questions from a variety of perspectives, and yet we still lack a coherent and mechanistic understanding of what drives these patterns. One process that is shared by all of life on Earth is metabolism. The development and testing of metabolic scaling theory (MST), which formalizes relationships between body size, temperature and metabolism, has revealed remarkable generality in the way that organisms respond to the environment. In spite of extensive documentation of cross-species metabolic patterns, we still lack evidence for how metabolic constraints propagate from the fine to the broad organizational scales. The large gap in our understanding at the level of populations presents a critical challenge for MST. I have combined theory, experiments and data synthesis to test the metabolic underpinnings of biodiversity and its implications for human well-being. Results showed that the temperature-dependence of population dynamics can be predicted from the temperature-dependence of individual metabolism, thus lending strong support for the role of energetic constraints in governing population growth and abundance. Further, I showed that variation in ecologically important traits such as body size has important implications for the nutritional value of aquatic species assemblages, thus linking the processes that structure ecosystems with the benefits they provide. This approach has revealed that understanding what generates and maintains aquatic biodiversity has direct and immediate consequences for human well-being.

description: We consider the two-color photooassociation of a quantum degenerate atomic gas into ground-state diatomic molecules via a molecular dark state. This process can be described in terms of a lambda level scheme that is formally analogous to the situation in electromagnetically-induced transparency (EIT) in atomic systems, and therefore can result in slow light propagation. We show that the group velocity of the light field depends explicitly on whether the atoms are bosons or fermions, as well as on the existence or absence of a pairing gap in the case of fermions, so that the measurement of the group velocity realizes a non-destructive diagnosis of the atomic state and the pairing gap.

Flexible Analog Circuits based on Oxide Thin-Film Transistors: from Modelling to Applications
Creators: name: Petti, Luisa
Publisher: name: Zenodo
Year: 2021

description: Recently flexible electronics has experienced tremendous advances, enabling the demonstration and sometimes also commercialization of foldable displays, conformable tags, and wearable monitoring systems. Besides sensors, actuators, and antennas, also flexible analog circuits allowing signal conditioning and communication are extremely needed. Among state-of-the-art technologies employing low-temperature processes, InGaZnO (IGZO) thin-film-transistors (TFTs) are especially suited to realize flexible analog circuits with good electrical and mechanical performance. Here, we report on the modelling, fabrication, and characterization of flexible IGZO TFTs and circuits. First, we show the DC and AC characteristics of devices fabricated on polyimide using Al2O3 insulators. Next, we present different approaches to reduce the TFT channel length (down to 160 nm), together with their influence on the AC performance. Best AC results are achieved for 500 nm-long self-aligned TFTs, yielding 135 MHz and 398 MHz transit and maximum oscillation frequencies, respectively. The applicability of such devices is then demonstrated in a broad range of fexible analog circuits, including different amplifiers and AM receivers/transceivers. Besides unipolar NMOS IGZO circuits, also CMOS amplifiers complementing IGZO with single-walled carbon nanotubes (SWCNTs) are also presented. Finally, we show how fully flexible sensor systems integrating magnetic sensors with IGZO operational amplifiers allow outperforming commercial rigid sensors.
Inertial waves in rotating bodies: a WKBJ formalism for inertial modes and a comparison with numerical results

description: (abbreviated) In this paper we develop a consistent WKBJ formalism, together with a formal first order perturbation theory for calculating the properties of the inertial modes of a uniformly rotating coreless body (modelled as a polytrope and referred hereafter to as a planet) under the assumption of a spherically symmetric structure. The eigenfrequencies, spatial form of the associated eigenfunctions and other properties we obtained analytically using the WKBJ eigenfunctions are in good agreement with corresponding results obtained by numerical means for a variety of planet models even for global modes with a large scale distribution of perturbed quantities. This indicates that even though they are embedded in a dense spectrum, such modes can be identified and followed as model parameters changed and that first order perturbation theory can be applied. This is used to estimate corrections to the eigenfrequencies as a consequence of the anelastic approximation, which we argue here to be small when the rotation frequency is small. These are compared with simulation results in an accompanying paper with a good agreement between theoretical and numerical results. The results reported here may provide a basis of theoretical investigations of inertial waves in many astrophysical and other applications, where a rotating body can be modelled as a uniformly rotating barotropic object, for which the density has, close to its surface, an approximately power law dependence on distance from the surface.

description: This article provides a general estimation and inference framework to study how different levels of program participation affect participants’ outcomes. We decompose differences in the outcome distribution into (i) a structure effect, arising due to the conditional outcome distributions given covariates associated with different levels of participation; and (ii) a composition effect, arising due to differences in the distributions of observable characteristics. These counterfactual differences are equivalent to the multivalued treatment effects for the treated under a conditional independence assumption. We propose efficient nonparametric estimators based on propensity score weighting together with uniform inference theory. We employ our methods to study the effects of the Workforce Investment Act (WIA) programs on participants’ earnings. We find that heterogeneity in levels of program participation is an important dimension to evaluate the WIA and other social programs in which participation varies. The results of this article, both theoretically and empirically, provide rigorous assessment of intervention programs and relevant suggestions to improve their performance and cost-effectiveness.

description: Employing tick-by-tick maximum likelihood estimation on several leading models from the financial economics literature, we find that the market microstructure noise is mostly explained by a linear model where the trade direction, that is, whether the trade is buyer or seller initiated, is multiplied by the dynamic quoted bid-ask spread. Although reasonably stable intraday, this model manifests variability across days and stocks. Among different observable high frequency financial characteristics of the underlying stocks, this variability is best explained by the tick-to-spread ratio, implying that discreteness is the first residual source of noise. We determine the bid-ask bounce effect as the next source of noise.

description: We present here evidence for the observation of the magneto-hydrodynamic (MHD) sausage modes in magnetic pores in the solar photosphere. Further evidence for the omnipresent nature of acoustic global modes is also found. The empirical decomposition method of wave analysis is used to identify the oscillations detected through a 4170 Å 'blue continuum' filter observed with the Rapid Oscillations in the Solar Atmosphere (ROSA) instrument. Out of phase, periodic behavior in pore size and intensity is used as an indicator of the presence of magneto-acoustic sausage oscillations. Multiple signatures of the magneto-acoustic sausage mode are found in a number of pores. The periods range from as short as 30 s up to 450 s. A number of the magneto-acoustic sausage mode oscillations found have periods of 3 and 5 minutes, similar to the acoustic global modes of the solar interior. It is proposed that these global oscillations could be the driver of the sausage type magneto-acoustic MHD wave modes in pores.

description: One income or wealth distribution is said to Lorenz dominate another when the Lorenz curve for the former is nowhere below that of the latter, indicating a (weakly) more equitable allocation of resources. Existing tests of the null of Lorenz dominance based on pairs of samples of income or wealth achieve the nominal rejection rate asymptotically when the two Lorenz curves are equal, but are conservative at other null configurations. We propose new nonparametric bootstrap tests of Lorenz dominance based on preliminary estimation of a contact set. Our tests achieve the nominal rejection rate asymptotically on the boundary of the null; that is, when Lorenz dominance is satisfied, and the Lorenz curves coincide on some interval. Numerical simulations indicate that our tests enjoy substantially improved power compared to existing procedures at relevant sample sizes.

description: Stars form with a complex and highly structured distribution. For a smooth star cluster to form from these initial conditions, the star cluster must erase this substructure. We study how substructure is removed using N-body simulations that realistically handle two-body relaxation. In contrast to previous studies, we find that hierarchical cluster formation occurs chiefly as a result of scattering of stars out of clumps, and not through clump merging. Two-body relaxation, in particular within the body of a clump, can significantly increase the rate at which substructure is erased beyond that of clump-merging alone. Hence the relaxation time of individual clumps is a key parameter controlling the rate at which smooth, spherical star clusters can form. The initial virial ratio of the clumps is an additional key parameter controlling the formation rate of a cluster. Reducing the initial virial ratio causes a star cluster to lose its substructure more rapidly.

description: Wave energy converters (WECs) can be expected to provide grid support services in future power systems. High levels of variable renewable energy (VRE), e.g., wind power, have posed many challenges in power system
 operation.
 The lessons learned through these challenges can anticipate future requirements for wave power integration.
 - Recent regulations have adopted more stringent requirements for VRE interconnection and developed new services for fast support.
 - In some networks, wind farms should provide grid support to ensure the security of supply, e.g., through frequency control and reactive power provision.
 - Such services were mainly provided by conventional synchronous generation in the past.

description: We study the bounds on tensor wave in a class of twisted inflation models where $D(4+2k)$-branes are wrapped on cycles in the compact manifold and wrap the KK-direction in the corresponding effective field theory. While the lower bound is found to be analogous to that in Type IIB models of brane inflation, the upper bound turns out to be significantly different. This is argued for a range of values for the parameter $g_s M$ satisfying the self-consistency relation and the WMAP data. Further, we observe that the wrapped $D8$-brane appears to be the most attractive from a cosmological perspective.

description: Increased vaccine hesitancy presents challenges to public health and undermines efforts to eradicate diseases such as measles, rubella, and polio. The decline is partly attributed to misconceptions that are shared on social media, such as the debunked association between vaccines and autism. Perhaps, more damaging to vaccine uptake are cases where trusted mainstream media run stories that exaggerate the risks associated with vaccines. It is important to understand the underlying causes of vaccine refusal, because these may be prevented, or countered, in a timely manner by educational campaigns. In this paper, we develop a dynamic model of vaccine compliance that can help pinpoint events that disrupted vaccine compliance. We apply the framework to Danish HPV vaccine data, which experienced a sharp decline in compliance following the broadcast of a controversial TV documentary, and we show that media coverage significantly predicts vaccine uptake.
Non-axisymmetric oscillations of stratified coronal magnetic loops with elliptical cross-sections

description: We study non-axisymmetric oscillations of a straight magnetic tube with an elliptic cross-section and density varying along the tube. The governing equations for kink and fluting modes in the thin tube approximation are derived. We found that there are two kink modes, polarised along the large and small axes of the elliptic cross-section. We have shown that the ratio of frequencies of the first overtone and fundamental harmonic is the same for both kink modes and independent of the ratio of the ellipse axes. On the basis of this result we concluded that the estimates of the atmospheric scale height obtained using simultaneous observations of the fundamental harmonic and first overtone of the coronal loop kink oscillations are independent of the ellipticity of the loop cross-section.
Spatiotemporal and directional properties of visual neurons in the lentiformis mesencephali of the zebra finch and hummingbird
Creators: name: Smyth, Graham
Publisher: name: University of British Columbia
Year: 2021

description: A moving animal experiences global visual signals across the entire retina known as optic flow, one of the key signals used in the visual guidance of locomotion. Optic flow sensitive neurons have been identified in the midbrains of all vertebrate classes. In birds, these neurons are found in the nucleus of the basal optic root (nBOR) and the pretectal nucleus lentiformis mesencephali (LM). These cells are known to exhibit large receptive fields in the contralateral eye, are excited by visual motion in a “preferred” direction and are inhibited by motion in the opposite direction. A key question is whether the response properties of LM neurons are conserved across species or are LM neurons specialized in animals that use different locomotor strategies. Previous studies in pigeons have investigated the responses of neurons in the LM and nBOR to drifting sine-wave gratings and discovered that they are tuned in the spatiotemporal domain. The LM typically contains cells that respond maximally to fast stimuli and are tuned to temporal frequency whereas nBOR cells respond maximally to slower stimuli and are velocity-tuned. Here we ask whether zebra finches and hummingbirds, specialized for different modes of locomotion, exhibit spatiotemporal specializations in optic flow neurons that may be related to their form of locomotion. We explored this question by making extracellular recordings in the LM of anesthetized birds while presenting drifting sine-wave gratings to the contralateral eye. These results were compared with previous pigeon data and we found that each of the three species exhibits distinct tuning in the spatiotemporal domain. Hummingbird LM neurons are tuned to the fastest stimuli, which were typically of lower spatial frequencies. Both hummingbird and finch LM cells exist almost exclusively as fast cells with 90% of peaks in the fast zone. Moreover, in pigeons, only ‘slow’ cells are velocity tuned, whereas both zebra finches and hummingbirds have ‘fast’ cells that are velocity tuned. These species-specific differences are suggestive of neural specializations for different optic flow behavior.

description: We use the density-matrix renormalization group method to investigate ground-state and dynamic properties of the one-dimensional Bose-Hubbard model, the effective model of ultracold bosonic atoms in an optical lattice. For fixed maximum site occupancy $n_b=5$, we calculate the phase boundaries between the Mott insulator and the `superfluid' phase for the lowest two Mott lobes. We extract the Tomonaga-Luttinger parameter from the density-density correlation function and determine accurately the critical interaction strength for the Mott transition. For both phases, we study the momentum distribution function in the homogeneous system, and the particle distribution and quasi-momentum distribution functions in a parabolic trap. With our zero-temperature method we determine the photoemission spectra in the Mott insulator and in the `superfluid' phase of the one-dimensional Bose-Hubbard model. In the insulator, the Mott gap separates the quasi-particle and quasi-hole dispersions. In the `superfluid' phase the spectral weight is concentrated around zero momentum.

description: In this paper, we present the results of Monte Carlo simulations of $γ$-ray and cosmic ray proton induced extensive air showers as detected by the TACTIC atmospheric Cherenkov imaging telescope for optimizing its trigger field of view and topological trigger generation scheme. The simulation study has been carried out at several zenith angles. The topological trigger generation uses a coincidence of 2 or 3 nearest neighbour pixels for producing an event trigger. The results of this study suggest that a trigger field of 11$\times$11 pixels ($\sim$ $3.4^o$ $\times$ $3.4^o$) is quite optimum for achieving maximum effective collection area for $γ$-rays from a point source. With regard to optimization of topological trigger generation, it is found that both 2 or 3 nearest neighbour pixels yield nearly similar results up to a zenith angle of ~$25^o$ with a threshold energy of $\sim$ 1.5 TeV for $γ$-rays. Beyond zenith angle of ~$25^o$, the results suggest that a 2-pixel nearest neighbour trigger should be preferred. Comparison of the simulated integral rates has also been made with corresponding measured values for validating the predictions of the Monte Carlo simulations, especially the effective collection area, so that energy spectra of sources (or flux upper limits in case of no detection) can be determined reliably. Reasonably good matching of the measured trigger rates (on the basis of $\sim$ 207 hours of data collected with the telescope in NN-2 and NN-3 trigger configurations) with that obtained from simulations reassures that the procedure followed by us in estimating the threshold energy and detection rates is quite reliable.

description: We present colours of sources detected with the Herschel/SPIRE instrument in deep extragalactic surveys of the Lockman Hole, Spitzer-FLS, and GOODS-N fields in three photometric bands at 250, 350 and 500 micrometers. We compare these with expectations from the literature and discuss associated uncertainties and biases in the SPIRE data. We identify a 500 micrometer flux limited selection of sources from the HerMES point source catalogue that appears free from neighbouring/blended sources in all three SPIRE bands. We compare the colours with redshift tracks of various contemporary models. Based on these spectral templates we show that regions corresponding to specific population types and redshifts can be identified better in colour-flux space. The redshift tracks as well as the colour-flux plots imply a majority of detected objects with redshifts at 1

On universal oracle inequalities related to high-dimensional linear models

Publisher: name: arXiv
Year: 2010
Subjects: subject: Statistics Theory (math.ST)

description: This paper deals with recovering an unknown vector $θ$ from the noisy data $Y=Aθ+σξ$, where $A$ is a known $(m\times n)$-matrix and $ξ$ is a white Gaussian noise. It is assumed that $n$ is large and $A$ may be severely ill-posed. Therefore, in order to estimate $θ$, a spectral regularization method is used, and our goal is to choose its regularization parameter with the help of the data $Y$. For spectral regularization methods related to the so-called ordered smoothers [see Kneip Ann. Statist. 22 (1994) 835--866], we propose new penalties in the principle of empirical risk minimization. The heuristical idea behind these penalties is related to balancing excess risks. Based on this approach, we derive a sharp oracle inequality controlling the mean square risks of data-driven spectral regularization methods.

Sharing space : an examination of the relationship between child-constructed spaces and spatial empowerment in a selection of children’s picturebooks
Creators: name: Anctil, Emily
Publisher: name: University of British Columbia
Year: 2018

description: A common feature of playtime for children is the building and using of spaces. Whether it be a blanket draped over a table with stacks of books and toys underneath, a wardrobe filled with blankets and pillows, or a tree house furnished with various household objects, children enjoy claiming spaces of their own in which to retreat from a predominantly adult-structured world. This thesis project looks closely at the process of childhood space-building through the lens of a selection of two children’s picturebooks: "Soft House", written by Jane Yolen and illustrated by Wendy Anderson Halperin, and "The Fort That Jack Built", written by Boni Ashburn and illustrated by Brett Helquist. I propose that the security and autonomy of children’s real-life constructed spaces are discoverable under the surface of picturebooks that depict this type of play behaviour, particularly when performed within adult-controlled domestic space. Drawing on scholar Jerry Griswold’s theory of “snugness” ("Feeling Like A Kid"), I perform close readings of the selected picturebooks utilizing the work of Lawrence Sipe (“Picturebooks as Aesthetic Objects”) and Denise E. Agosto (“Interdependent Storytelling”). The findings of this thesis suggest that although domestic space is depicted as belonging thoroughly and completely to adults, child-constructed spaces empower children to set spatial boundaries, cultivate feelings of safety and security, rehearse adult responsibilities, and engage in imaginative play. The thesis proposes that snugness and child spatial empowerment are intrinsically linked, and that a negotiation between adults and children must occur if these spaces are to be successfully created and used inside the domestic household.

description: This paper provides a general estimation and inference framework to study how different levels of program participation affect participants’ outcomes. We decompose differences in the outcome distribution into (i) a structure effect, arising due to the conditional outcome distributions given covariates associated with different levels of participation; and (ii) a composition effect, arising due to differences in the distributions of observable characteristics. These counterfactual differences are equivalent to the multivalued treatment effects for the treated under a conditional independence assumption. We propose efficient nonparametric estimators based on propensity score weighting together with uniform inference theory. We employ our methods to study the effects of the Workforce Investment Act (WIA) programs on participants’ earnings. We find that heterogeneity in levels of program participation is an important dimension to evaluate the WIA and other social programs in which participation varies. The results of this paper, both theoretically and empirically, provide rigorous assessment of intervention programs and relevant suggestions to improve their performance and cost-effectiveness.

description: Employing tick-by-tick maximum likelihood estimation on several leading models from the financial economics literature, we find that the market microstructure noise is mostly explained by a linear model where the trade direction, i.e. whether the trade is buyer or seller initiated, is multiplied by the dynamic quoted bid-ask spread. Although reasonably stable intraday, this model manifests variability across days and stocks. Among different observable high frequency financial characteristics of the underlying stocks, this variability is best explained by the tick-to-spread ratio, implying that discreteness is the first residual source of noise. We determine the bid-ask bounce effect as the next source of noise.

description: Inflation forecasting is an important but difficult task. Here, we explore advances in machine learning (ML) methods and the availability of new datasets to forecast U.S. inflation. Despite the skepticism in the previous literature, we show that ML models with a large number of covariates are systematically more accurate than the benchmarks. The ML method that deserves more attention is the random forest model, which dominates all other models. Its good performance is due not only to its specific method of variable selection but also the potential nonlinearities between past key macroeconomic variables and inflation.

description: It is found that the scattering of the fragile nucleus $^6$Li from $^{12}$C and $^{16}$O is unexpectedly transparent. It is shown that the internal-wave contribution is significantly large in the scattering, which suggests that some transparency could persist in the scattering involving the fragile nucleus $^6$He.

description: We present a new backward evolution model for galaxies and AGNs in the infrared (IR). What is new in this model is the separate study of the evolutionary properties of the different IR populations (i.e. spiral galaxies, starburst galaxies, low-luminosity AGNs, "unobscured" type 1 AGNs and "obscured" type 2 AGNs) defined through a detailed analysis of the spectral energy distributions (SEDs) of large samples of IR selected sources. The evolutionary parameters have been constrained by means of all the available observables from surveys in the mid- and far-IR (source counts, redshift and luminosity distributions, luminosity functions). By decomposing the SEDs representative of the three AGN classes into three distinct components (a stellar component emitting most of its power in the optical/near-IR, an AGN component due to hot dust heated by the central black hole peaking in the mid-IR, and a starburst component dominating the far-IR spectrum) we have disentangled the AGN contribution to the monochromatic and total IR luminosity emitted by the different populations considered in our model from that due to star-formation activity. We have then obtained an estimate of the total IR luminosity density (and star-formation density - SFD - produced by IR galaxies) and the first ever estimate of the black hole mass accretion density (BHAR) from the IR. The derived evolution of the BHAR is in agreement with estimates from X-rays, though the BHAR values we derive from IR are slightly higher than the X-ray ones. Finally, we have simulated source counts, redshift distributions and SFD and BHAR that we expect to obtain with the future cosmological Surveys in the mid-/far-IR that will be performed with JWST-MIRI and SPICA-SAFARI.

CaII and H$α$ flaring M dwarfs detected with multi-filter photometry

description: Understanding and characterising the magnetic activity of M dwarfs is of paramount importance in the search for Earth-like exoplanets orbiting them. Energetic stellar activity phenomena, such as flares or coronal mass ejections, which are common in these stars, are deeply connected with the habitability and atmospheric evolution of the surrounding exoplanets. We present a follow-up of a sample of M dwarfs with strong H$α$ and CaII H and K emission lines identified with J-PLUS photometry in a previous work. We collected low-resolution NOT/ALFOSC and GTC/OSIRIS spectra, measuring the PC3 index for the spectral type determination. We used two-minute-cadence calibrated TESS light curves to identify and characterise multiple flares and to calculate the rotation period of the two active M dwarfs found in our sample. We confirm that the strong emission lines detected in the J-PLUS photometry are caused by transient flaring activity. We find clear evidence of flaring activity and periodic variability for LP 310-34 and LP 259-39, and estimated flare energies in the TESS bandpass between $7.4\times10^{30}$ and $2.2\times10^{33}$ erg for them. We characterised LP 310-34 and LP 259-39 as very rapidly rotating M dwarfs with CaII H and K and H$α$ in emission, and computed a rotation period for LP 259-39 for the first time: $P_{\rm rot}=1.69\pm0.02$ d. This work advocates the approach of exploiting multi-filter photometric surveys to systematically identify flaring M dwarfs, especially to detect episodes of strong CaII H and K line emission, which may have important implications for exoplanetary space weather and habitability studies. Our results reveal that common M dwarfs experience flare events in CaII H and K in addition to well known H$α$ flares.

description: We perform direct numerical simulations of the tidal encounter of a rotating planet on a highly eccentric or parabolic orbit about a central star formulated as an initial value problem. This approach enables us to extend previous work of Ivanov & Papaloizou to consider planet models with solid cores and to avoid making an anelastic approximation. We obtain a power spectrum of the tidal response of coreless models which enables global inertial modes to be identified. Their frequencies are found to be in good agreement with those obtained using either a WKBJ approach or the anelastic spectral approach adopted in previous work for small planet rotation rates. We also find that the dependence of the normal mode frequencies on the planet angular velocity in case of higher rotation rates can for the most part be understood by applying first order perturbation theory to the anelastic modes. We calculate the energy and angular momentum exchanged as a result of the tidal encounter and for coreless models again find good agreement with results obtained using either the anelastic spectral method. Models with a solid core showed evidence of the emission of shear layers at critical latitudes and possibly wave attractors after the encounter but the total energy exchanged during the encounter did not differ dramatically from the coreless case as long as the ratio of the core radius to the total radius was less than 50%, there being hardly any difference at all when this ratio was less than 25% of the total radius. We give a physical and mathematical interpretation of this result. Finally we are able to validate the use of the anelastic approximation for both the work presented here and our previous work which led to estimates of circularisation rates for planets in highly eccentric orbits.

description: This Open Data Management Plan is related to the task of managing open data and open access publications in the project. The task sets up a dedicated open access repository, integrated with ResearchGate, Mendeley and/or MyScienceWork. The repository will include two components, one focusing on publication and the other on data. In addition to the open access journals they are published in, all publications will join the MyScienceWork global database of over 30M scientific publications and be visible by the large community of MyScienceWork members (researchers, science journalist, science fans, founders, industry partners, etc.). The dedicated open access repository will centralize all project-related publications (scientific articles, pre-prints, patents or conference publications, presentation, etc.) in a dedicated institutional repository, together with automatically populated structured metadata. The portal will include a built-in validation workflow for project administrators to check and validate the publication import, its metadata and license information. The open access repository will be fully integrated with OpenAIRE, enabling the automatic transfer of publications to OpenAIRE in order to maximize open access dissemination capabilities. The task will also result in a data management plan delivered at M6 and updated throughout the project, whenever important changes to the project occur due to inclusion of new data sets, changes in consortium policies or external factors.
