description: Efforts by content creators and social networks to enforce legal and policy-based norms, e.g. blocking hate speech and users, has driven the rise of unrestricted communication platforms. One such recent effort is Dissenter, a browser and web application that provides a conversational overlay for any web page. These conversations hide in plain sight - users of Dissenter can see and participate in this conversation, whereas visitors using other browsers are oblivious to their existence. Further, the website and content owners have no power over the conversation as it resides in an overlay outside their control. In this work, we obtain a history of Dissenter comments, users, and the websites being discussed, from the initial release of Dissenter in Feb. 2019 through Apr. 2020 (14 months). Our corpus consists of approximately 1.68M comments made by 101k users commenting on 588k distinct URLs. We first analyze macro characteristics of the network, including the user-base, comment distribution, and growth. We then use toxicity dictionaries, Perspective API, and a Natural Language Processing model to understand the nature of the comments and measure the propensity of particular websites and content to elicit hateful and offensive Dissenter comments. Using curated rankings of media bias, we examine the conditional probability of hateful comments given left and right-leaning content. Finally, we study Dissenter as a social network, and identify a core group of users with high comment toxicity.

description: Distributed systems are now both very large and highly dynamic. Peer to peer overlay networks have been proved efficient to cope with this new deal that traditional approaches can no longer accommodate. While the challenge of organizing peers in an overlay network has generated a lot of interest leading to a large number of solutions, maintaining critical data in such a network remains an open issue. In this paper, we are interested in defining the portion of nodes and frequency one has to probe, given the churn observed in the system, in order to achieve a given probability of maintaining the persistence of some critical data. More specifically, we provide a clear result relating the size and the frequency of the probing set along with its proof as well as an analysis of the way of leveraging such an information in a large scale dynamic distributed system.

EU's Legal and Policy Framework of Migration Returns

description: Work Package 2 (WP2) of the GAPs Project (Legal and Policy Frameworks of Returns in the EU) focuses on the legal, institutional and policy frameworks regarding the return and readmission policies at the EU level and in the five selected EU member consortium countries (Sweden, Poland, Germany, Greece, Netherlands) as well as the related gaps. Three country snapshots of the non-consortium EU Member States (Italy, France, and Hungary) are also provided.

This comparative report is based on the examination and comparison of the return policies of the selected countries through the country dossiers that are provided as annexes of this report (see other reports in GAPs-WP2 publication series). It aims to identify the commonalities and variances within their legal and policy structures concerning the return of migrants against the backdrop of overarching EU directives, particularly the EU Return Directive. This exploration includes a comprehensive examination of fundamental statistics, significant political changes in this realm, and a comparative analysis of the institutional frameworks.

The core legal framework addressed in the report is distilled into three sub-sections, pinpointed byexamining the identified “gaps” across all reports. These prominent areas of concern, “Procedure to Issue Return Decisions”, “Procedural Safeguards and Non-Returnability”, and “Detention”, have been analysed comparatively.

description: We consider the framework of quintessential inflation in the warm background which is caused by the dissipation of the scalar field energy density into relativistic degrees of freedom. The dissipation process has important consequences for the evolution both at the levels of background as well as perturbation and allows us to easily satisfy the observational constraints.~Our numerical analysis confirms that the model conforms to observational constraints even if the field-radiation coupling strength is weak. In the warm background, we investigate the post inflationary evolution of relic gravity waves produced during inflation whose amplitude is constrained by the Big Bang Nucleosynthesis constraint. Further, we investigate the effect of coupling on the amplitude of gravity waves and obtain the allowed phase space between the model parameters. The mechanism of quintessential inflation gives rise to the blue spectrum of gravitational wave background at high frequencies. We discuss the perspectives of detection of the signal of relic gravity waves by future proposed missions. Improvements of their sensitivities in the high-frequency regime, in the future, might allow us to probe the blue tilt of the spectrum caused by the presence of a kinetic regime in the underlying framework of inflation.

description: We explore the 1-loop renormalization group flow of two models coming from a generalization of the Connes-Lott version of Noncommutative Geometry in Lorentzian signature: the Noncommutative Standard Model and its B-L extension. Both make predictions on coupling constants at high energy, but only the latter is found to be compatible with the top quark and Higgs boson masses at the electroweak scale. We took into account corrections introduced by threshold effects and the relative positions of the Dirac and Majorana neutrino mass matrices and found them to be important. Some effects of 2-loop corrections are briefly discussed. The model is consistent with experiments only for a very small part of its parameter space and is thus predictive. The masses of the $Z'$ and B-L breaking scalar are found to be of the order $10^{14}$ GeV.

description: ABSTRACT: This research examines innovation resistance to a mobile banking and digital money initiative in rural communities. Despite studies on the impact of mobile banking applications on increasing financial inclusion, there is still a dearth of research on why innovation resistance persists in traditional, rural communities, particularly with respect to gender. This qualitative case study uses semi-structured interviews, participant observation, and semiotics to unpack the causes of resistance in a rural town and use this experience to elaborate on existing innovation theories. We conceptualise four factors that contributed to innovation resistance and highlight the need for a multi-faceted approach to addressing financial isolation in rural sectors. The themes embodied within these factors include the reconfiguration of rural life, the dematerialisation of cash, local and regional politics and gender relations. This case serves as an example of the historical situatedness of knowledge and the intersubjective nature of human and social relations that affect technology acceptance. This is one of the first studies to apply active and passive innovation resistance literature to a rural context. We hoped to have emphasised a need to rethink digital initiatives for financial inclusion in rural communities. Furthermore, the idiosyncrasies of this case call for revisiting mainstream innovation resistance models to draw on interdisciplinary approaches that facilitate financial inclusion for marginalised communities.

description: The Verwey phase transition in magnetite is analyzed on the basis of the Landau theory. The free energy functional is expanded in a series of components belonging to the primary and secondary order parameters. A low-temperature phase with the monoclinic P2/c symmetry is a result of condensation of two order parameters X_3 and Δ_5 . The temperature dependence of the shear elastic constant C_44 is derived and the mechanism of its softening is discussed.

description: O concelho de Santa Cruz, costa sul da Madeira, com 81,5 km2, tem 4 patamares climáticos e diferentes condições agroecológicas. A evolução da agrodiversidade iniciou-se, com o povoamento, e sofreu alterações históricas e geográficas. Num primeiro período, a agrodiversidade biofísica, específica e intraespecífica aumentou e diversificou-se, devido à construção de agrossistemas, introdução de culturas, sucessão de ciclos agrícolas, adaptação às condições agroecológicas, pragas, doenças ou ação do homem. Neste período está documentada a introdução de um elevado número de espécies agrícolas e o aparecimento de variedades locais. Num período posterior, a agrodiversidade sofreu uma drástica redução, com a diminuição das áreas agrícolas, abandono das culturas, extinção de variedades locais ou espécies agrícolas. Os registos históricos indicam a utilização de 72 espécies “agrícolas”, no concelho. As referências documentais indicam como culturas mais importantes o trigo, vinha, cana-sacarina, cevada, centeio e sumagre. Várias outras culturas desempenharam, um papel importante na economia do concelho, sendo cultivadas para fins alimentares, comerciais, industriais, culturais ou religiosos. A distribuição e adaptação destas espécies aos agrossistemas e condições agroecológicas deu origem a um número indeterminado de variedades locais. Apesar das limitações dos registos históricos algumas variedades locais remontam a entre 500 a 140 anos, nomeadamente o trigo da serra, castas malvasia e tinta antiga de Gaula, pêra caniça, banana da terra, feijão corno de carneiro e couve de João Ferino, que podem ser relacionadas com a histórica do concelho. A análise desta agrodiversidade foi realizada, a fim de estabelecer as alterações históricas e geográficas ocorridas em 11 culturas representativas do concelho.

description: Neste estudo pretendeu-se avaliar a possibilidade da reutilização de um efluente vinícola (EV) tratado para rega de espécies ornamentais. Para tal, realizaram-se inicialmente testes de fitotoxicidade em sementes de Lepidium sativum e de uma mistura de relva, sujeitas a concentrações crescentes de EV e um ensaio de rega em Petunia x atkinsiana com diferentes tratamentos: EV sem diluição (EV100%), efluente diluído (EV60%), efluente com correção de pH (EVT) e controlo (EV0%). Após o ensaio, realizaram-se análises morfo-fisiológicas e bioquímicas. Os testes revelaram que as concentrações de EV potenciaram a germinação da mistura de relva, apesar de terem sido moderadamente fitotóxicas para L. sativum (Índice de Germinação de 76,7 %). Relativamente ao ensaio de rega, os tratamentos EV0% e EV100% destacaram-se positivamente em relação aos EV60% e EVT, ao nível do crescimento e anatomia foliar. Contudo, não ocorreram alterações nas concentrações foliares de pigmentos fotossintéticos (P = 0,946) e fenóis totais (P = 0,126) e antocianinas totais nas flores (P = 0,918). Concluiu-se que a reutilização de EVs na rega de petúnias poderá ser uma alternativa sustentável, pois as caraterísticas visuais e estéticas como a cor e o número de flores, que são valorizadas comercialmente em espécies ornamentais, não foram alteradas.

description: Objective. Perform the screening of the ZES manifestations аt stomach NEO, to study their clinical and morphological features. Methods. The histories of morbid and biopsied and surgical specimens of 21 patients with stomach NET were investigated.  The usual methods and the IHC study were used. Results.  62% of patients were conducted 2 – 6 biopsies from the stomach mucosa. Hyperplastic epithelial, muscle and endocrine cells changes were revealed.  18 tumors were regarded as G1, 3 – as G 2-3 with invasive growth in the muscular layer.  The patients mean age was 50, 2 years. 4 patients (19%) had different symptoms of ZES. The key clinical symptoms were manifestations of aggressive course of peptic ulcers in the form of complications (bleeding, stomach obstruction). 75% of patients were men.  Their mean age was 25 years. Tumors had sizes from 0.1 to 1.0 cm and were detected or during the operation (50%), or after gastric resection (50%). NET diagnosis was put on histological examination, verified and refined by IHC study. Conclusion. NETs in the stomach with the manifestations of ZES may be multiple, very small, which requires at examination multiple parallel slices of resected stomach wall and a thorough search of neoplasms.

description: In this study we investigate the nuclear quantum effects (NQEs) on the acidity constant (pKA) of liquid water isotopologues at the ambient condition by path integral molecular dynamics (PIMD) simulations. We compared simulations using a fully explicit solvent model with a classical polarizable force field, density functional tight binding, and ab initio density functional theory, which correspond to empirical, semiempirical, and ab initio PIMD simulations, respectively. The centroid variable with respect to the proton coordination number of a water molecule was restrained to compute the gradient of the free energy, which measures the reversible work of the proton abstraction for the quantum mechanical system. The free energy curve obtained by thermodynamic integration was used to compute the pKA value based on probabilistic determination. This technique not only reproduces the pKA value of liquid D2O experimentally measured (14.86) but also allows for a theoretical prediction of the pKA values of liquid T2O, aqueous HDO and HTO which are unknown due to its scarcity. It is also shown that the NQEs on the free energy curve can result in a downshift of 4.5 +/- 0.9 pKA units in the case of liquid water, which indicates that the NQEs plays an indispensable role in the absolute determination of pKA. The results of this study can help to inform further extensions into the calculation of the acidity constants of isotope substituted species with high accuracy.

description: In this short note I discuss the hypothesis that bursting activity of magnetars evolves in time analogously to the glitching activity of normal radio pulsars (i.e. sources are more active at smaller ages), and that the increase of the burst rate follows one of the laws established for glitching radio pulsars. If the activity of soft gamma repeaters decreases in time in the way similar to the evolution of core-quake glitches ($\propto t^{5/2}$), then it is more probable to find the youngest soft gamma repeaters, but the energy of giant flares from these sources should be smaller than observed $10^{44}$ --$10^{46}$ ergs as the total energy stored in a magnetar's magnetic field is not enough to support thousands of bursts similar to the prototype 5 March 1979 flare.

description: Much work has been done to investigate social jetlag, a misalignment between the biological clock and the social agenda caused by exposition to different light inputs, that causes several health issues. To investigate synchronization and attractors due to a sequence of light inputs, we introduce an extension of a model, previously used to describe jetlag caused by a single change in the light input. The synchronization to the light input is sensitive to the control parameters of the system and to the light input periods. Depending on the parameter set, the observed synchronization is with one or another successive light input. Most of the solutions have the period of a light input. However, for some parameters, we also observed higher period, chaotic solutions, and bistability.

description: For almost two decades schizophrenia has been considered to be a functional disconnection disorder. This functional disconnectivity between several brain regions could have a neurodevelopmental origin. Various approaches suggest the ventral subiculum (SUB) is a particular target region for neurodevelopemental disturbances in schizophrenia. It is also commonly acknowledged that there is a striatal dopaminergic (DA) dysregulation in schizophrenia which may depend on a subiculo-striatal disconnection involving glutamatergic NMDA receptors. The present study was designed to investigate, in adult rats, the effects of the non-competitive NMDA receptor antagonist ketamine on DA responses in the ventral striatum, or, more specifically, the core part of the nucleus accumbens (Nacc), following postnatal functional inactivation of the SUB. Functional inactivation of the left SUB was carried out by local tetrodotoxin (TTX) microinjection at postnatal day 8 (PND8), i.e. at a critical point in the neurodevelopmental period. DA variations were recorded using in vivo voltammetry in freely moving adult rats (11 weeks). Locomotor activity was recorded simultaneously with the extracellular levels of DA in the core part of the Nacc. Data obtained during the present study showed that after administration of ketamine, the two indexes were higher in TTX animals than PBS animals, the suggestion being that animals microinjected with TTX in the left SUB at PND8 present greater reactivity to ketamine than animals microinjected with PBS. These findings could provide new information regarding the involvement of NMDA glutamatergic receptors in the core part of the Nacc in the pathophysiology of schizophrenia.
Stability and change of killer whale (Orcinus orca) dialects
Creators: name: Deeke, Volker Bernt
Publisher: name: University of British Columbia
Year: 2009

description: Vocal dialects have been described in many species, but most studies so far have focused on territorial species such as songbirds and humans. This study investigates patterns of structural variation in the stereotyped calls of 9 matrilineal units of killer whales (Orcinusorca) with congruent home ranges. In Chapter I, I describe an index of acoustic similarity based on neural network analysis of frequency contours. I test this index on simulated signals, and compare it to similarity ratings from three human subjects. The index could discriminate along global differences in contour frequency, as well as localized differences in frequency and shape. It rated similarity comparably to humans, since differences between ratings among subjects exceeded differences between subject ratings and the neural network index. In the second Chapter, I analyse 2 call types used by 2 groups over a 12 year period to identify mechanisms of vocal differentiation. A test for structural modification detected significant changes in one call type in both groups, but not in the other. The rate of differentiation between both groups was significantly lower for the modified call type than the rate of modification in one group showing that modifications are transmitted between groups. Results of an analysis of structural parameters are consistent with a theory of structural drift. In Chapter III, I quantify patterns of structural variation for 4 call types shared by 9 matrilineal units. Patterns are consistent across some call types, and similarity ratings for two call types are correlated with the frequency of association among groups. This presents additional evidence for the role of cultural transmission in maintaining structural similarity of shared calls. This study shows that discrete calls of killer whales are modifiable behavioural traits and transmitted through learning. Since multiple vocal traditions persist in spite of frequent acoustic contact between their members, this study presents evidence for selective copying in resident killer whales. If association patterns reflect kinship among matrilineal units as they do among individuals and among communities, similarity of shared call types indicates the degree of maternal relatedness, and may function in kin recognition or mate choice.

description: Little Higgs models with T parity contain an attractive dark matter candidate, the heavy photon. We compute the cross section of the heavy photon annihilation into Z-photon pairs, which turns out to be substantially higher than the previously computed cross section for the two photon final state. Unfortunately, even with this enhancement, the monochromatic photon flux from galactic heavy photon annihilation is unlikely to be detectable by GLAST or the currently operating atmospheric Cerenkov telescopes. We also compute the flux of high-energy neutrinos from the annihilation of the heavy photons captured by the Sun and the Earth. The maximum flux of upward-going muons due to such neutrinos is about 1 yr^{-1}km^{-2}.

description: Here we aim to explore the origin of the strong C2H lines to reimagine the chemistry of protoplanetary disks. There are a few key aspects that drive our analysis. First, C2H is detected in young and old systems, hinting at a long-lived chemistry. Second, as a radical, C2H is rapidly destroyed, within <1000 yr. These two statements hint that the chemistry responsible for C2H emission must be predominantly in the gas-phase and must be in equilibrium. Combining new and published chemical models we find that elevating the total volatile (gas and ice) C/O ratio is the only natural way to create a long lived, high C2H abundance. Most of the \ce{C2H} resides in gas with a Fuv/n-gas ~ 10^-7 G0 cm^3. To elevate the volatile C/O ratio, additional carbon has to be released into the gas to enable an equilibrium chemistry under oxygen-poor conditions. Photo-ablation of carbon-rich grains seems the most straightforward way to elevate the C/O ratio above 1.5, powering a long-lived equilibrium cycle. The regions at which the conditions are optimal for the presence of high C/O ratio and elevated C2H abundances in the gas disk set by the Fuv/n-gas ~ 10^-7 G0 cm^3 condition lie just outside the pebble disk as well as possibly in disk gaps. This process can thus also explain the (hints of) structure seen in C2H observations.

description: We present a spatially resolved 894 micron map of the circumstellar disk of the Butterfly star in Taurus (IRAS 04302+2247), obtained with the Submillimeter Array (SMA). The predicted and observed radial brightness profile agree well in the outer disk region, but differ in the inner region with an outer radius of ~80-120 AU. In particular, we find a local minimum of the radial brightness distribution at the center, which can be explained by an increasing density / optical depth combined with the decreasing vertical extent of the disk towards the center. Our finding indicates that young circumstellar disks can be optically thick at wavelengths as long as 894 micron. While earlier modeling lead to general conclusions about the global disk structure and, most importantly, evidence for grain growth in the disk (Wolf, Padgett, & Stapelfeldt 2003), the presented SMA observations provide more detailed constraints for the disk structure and dust grain properties in the inner, potentially planet-forming region (inside ~80-120 AU) vs. the outer disk region (~120-300 AU).

description: The main purpose of this work is to perform an analysis of realistic new trajectories for a robotic mission to Saturn's largest moon, Titan, in order to demonstrate the great advantages related to the Direct Fusion Drive (DFD). The DFD is a D -$^3$He fuelled, aneutronic, thermonuclear fusion propulsion system. This fusion propulsion concept is based on a magnetically confined field reversed configuration plasma, where the deuterium propellant is heated by fusion products, and then expanded into a magnetic nozzle, providing both thrust and electrical energy to the spacecraft [1]. The trajectories calculations and analysis for the Titan mission are obtained based on the characteristics provided by the PPPL [1]. Two different profile missions are considered: the first one is a thrust-coast-thrust profile with constant thrust and specific impulse; the second scenario is a continuous and constant thrust profile mission. Each mission study is divided into four different phases, starting from the initial low Earth orbit departure, the interplanetary trajectory, Saturn orbit insertion and the Titan orbit insertion. For all mission phases, maneuver time and propellant consumption are calculated. The results of calculations and mission analysis offer a complete overview of the advantages in term of payload mass and travel time. It is important to emphasize that the deceleration capability is one of the DFD game changer: in fact, the DFD performance allows to rapidly reach high velocities and decelerate in even shorter time period. This capability results in a total trip duration of 2.6 years for the thrust-coast-thrust profile and less than 2 years considering the continuous thrust profile. The high payload enabling capability, combined with the huge electrical power available from the fusion reactor, leads to a tremendous advantage compared to present technology.

Direct Photons in Nuclear Collisions at FAIR Energies

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: Using the extrapolation of existing data estimations of prompt photon production at FAIR energies have been made. At $y=y_{c.m.}$ the rapidity density of prompt photons with $p_{t}>$ 1.5 GeV/c per central Au+Au event at 25 AGeV is estimated as $\sim 10^{-4}$ . With the planed beam intensity $10^{9}$ per second and 1% interaction probability, for 10% of most central events one can expect the prompt photon rate $\sim 10^{2}$ photons per second. Direct photons from the hadron scenario of ion collisions generated by the Hadron-String-Dynamics (HSD) transport approach with implemented meson scatterings $πρ\toπγ, ππ\toργ$ have been analyzed. Photons from short-living resonances (e.g. $ω\to π^{0} γ$) decaying during the dense phase of the collision should be considered as direct photons. They contribute significantly in the direct photon spectrum at $p_{t}=0.5 - 1$ GeV/c. At the FAIR energy 25 AGeV in Au+Au central collisions the HSD generator predicts, as a lower estimate, $γ_{direct}/γ_{π^{0}} \simeq$ 0.5% in the region $p_{t}=0.5 - 1$ GeV/c. At $p_{t}=1.5 - 2$ GeV/c $γ_{prompt}/γ_{π^{0}} \simeq$ 2%. Thermal direct photons have been evaluated with the Bjorken Hydro-Dynamics (BHD) model. The BHD spectra differ strongly from the HSD predictions. The direct photon spectrum is very sensitive to the initial temperature parameter $T_{0}$ of the model. The 10 MeV increase in the $T_{0}$ value leads to $\sim$ 2 times higher photon yield.

A Multi-Epoch Study of Radio Continuum Emission from MassiveProtostars

description: We report the results of the Jansky Very Large Array (JVLA) observation of five massive protostars at 6 and 22.2 GHz. The aim of the study was to compare their current fluxes and positions with previous observations to search for evidence of variability. Most of the observed sources present the morphologies of a thermal core, hosting the protostar and exhibiting no proper motion, and associated non-thermal radio lobes that are characterised by proper motions and located away from the thermal core. Some of the protostars drive jets whose lobes have dissimilar displacement vectors, implying precession of the jets or the presence of multiple jet drivers. The jets of the protostars were found to have proper motions that lie in the range 170$ \leq v \leq $650 kms$^{-1}$, and precessions of periods 40$\leq p \leq$50 years and angles 2$\leq α\leq$10$^\circ$, assuming that their velocities $v=$500 kms$^{-1}$. The core of one of the sources, S255 NIRS 3, which was in outburst at the time of our observations, showed a significant change in flux compared to the other sources. Its spectral index decreased during the outburst, consistent with the model of an expanding gas bubble. Modelling the emission of the outburst as that of a new non-thermal lobe that is emerging from a thermal core whose emission enshrouds that of the lobe also has the potential to account for the increase in flux and a decrease in the spectral index of the source's outburst.

Defect model for the mixed mobile ion effect
Creators: name: Belostotsky, Vladimir
Publisher: name: arXiv
Year: 2006
Subjects: subject: Materials Science (cond-mat.mtrl-sci)
subject: FOS: Physical sciences

description: This paper presents a new defect model for the mixed mobile ion effect. The essential physical concept involved is that simultaneous migration of two unlike mobile ions in mixed ionic glass is accompanied by expansion or contraction of the guest-occupied sites with distortion of surrounding glass matrix; in many cases, an intensity of the local stresses in glass matrix surrounding ionic sites occupied by foreign ions is much greater than, or at least comparable to the glass network binding energy. Hence, when the stress exceeds the breaking threshold, relaxation occurs almost immediately via the rupture of the bonds in the nearest glass matrix with generation of pairs of intrinsic structural defects. The specificity of the mechanism of defect generation leads to the clustering of negatively charged defects, so that rearranged sites act as high energy anion traps in glass matrix. This results in the immobilization of almost all minority mobile species and part of majority mobile species, so mixed mobile ion glass behaves as single mobile ion glass of much lower concentration of charge carriers. Generation of defects leads also to the depolymerization of glass network, which in turn results in the reduction of the glass viscosity and Tg as well as in the compaction of glass structure (thermometer effect). The magnitude of the mixed mobile ion effect is defined by the size mismatch of unlike mobile ions, their total and relative concentrations, the binding energy of the glass-forming network, and temperature. Although the proposed model is based upon the exploration of alkali silicate glass-forming system, the approach developed here can be easily adopted to other mixed ionic systems such as crystalline and even liquid ionic conductors.

description: The health care sector in Germany has become increasingly important in the scientific field of
information systems over the last decades. This development has been reinforced by the
demographic change and, more recently, by the current Covid-19 pandemic. Irrespective of the
field of work and application, digital interface processes, data acquisition, data exchange, as well
as data preparation, analysis, and correct archiving are undoubtedly gaining in importance. They
also enable new possibilities for service design and the corresponding provision of both digitized
supply services and digitized information services. Against the background of increasing and
more complex requirements in the health care system, digitalization can become a very important
factor in the provision of services. This is especially true for hospitals. In hospitals, increasing
data volume and level of detail increases the complexity of data documentation. Hospital staff
currently spend a lot of time on data acquisition and transfer, and correspondingly less time is
available for the beneficial core work with patients. Therefore, digitization and automation
strategies through patient-oriented interactions are becoming increasingly necessary. Patient
portals are one possible way to enable care and new services and to reduce the effort for
comprehensive data collection. This paper presents the current situation in Germany regarding
patient-oriented solutions by capturing, structuring, and analyzing the market of existing patient
portals in German hospitals. Existing portal functionalities are identified and patient portals are
evaluated against these functionalities. Our results show that there are only two patient portal
solutions in the largest hospitals in Germany and that the existing portal solutions by far do not
completely fulfill all functional categories. Based on these results, we develop and discuss further
research questions for future research. This includes especially design-oriented research with
regards to the digital patient journey.

description: In the last decade, the Kepler and CoRoT space-photometry missions have demonstrated the potential of asteroseismology as a novel, versatile and powerful tool to perform exquisite tests of stellar physics, and to enable precise and accurate characterisations of stellar properties, with impact on both exoplanetary and Galactic astrophysics. Based on our improved understanding of the strengths and limitations of such a tool, we argue for a new small/medium space mission dedicated to gathering high-precision, high-cadence, long photometric series in dense stellar fields. Such a mission will lead to breakthroughs in stellar astrophysics, especially in the metal poor regime, will elucidate the evolution and formation of open and globular clusters, and aid our understanding of the assembly history and chemodynamics of the Milky Way's bulge and few nearby dwarf galaxies.
