description: A unified diagrammatic treatment single and double electron photoemission currents is presented. The irreducible lesser density-density response function is the starting point of these derivations. Diagrams for higher order processes in which several electrons are observed in coincidence can likewise be obtained. For physically relevant situations in which the photoemission cross-section can be written as the Fermi Golden rule, the diagrams from the nonequilibrium Green's function approach can be put direct correspondence with that of the scattering theory.

description: Recent VLT/SPHERE near-infrared imaging observations revealed two spiral arms with a near m=2 rotational symmetry in the protoplanetary disk around the ~1.7 solar mass Herbig star HD 100453. A ~0.3 solar mass M dwarf companion, HD 100453 B, was also identified at a projected separation of 120 AU from the primary. In this Letter, we carry out hydrodynamic and radiative transfer simulations to examine the scattered light morphology of the HD 100453 disk as perturbed by the companion on a circular and coplanar orbit. We find that the companion truncates the disk at ~45 AU in scattered light images, and excites two spiral arms in the remaining (circumprimary) disk with a near m=2 rotational symmetry. Both the truncated disk size and the morphology of the spirals are in excellent agreement with the SPHERE observations at Y , J, H, and K1-bands, suggesting that the M dwarf companion is indeed responsible for the observed double-spiral-arm pattern. Our model suggests that the disk is close to face on (inclination angle ~5 degree), and that the entire disk-companion system rotates counterclockwise on the sky. The HD 100453 observations, along with our modeling work, demonstrate that double spiral arm patterns in near-infrared scattered light images can be generically produced by companions, and support future observations to identify the companions responsible for the arms observed in the MWC 758 and SAO 206462 systems.

description: Quantum steering is observed when performing appropriate local measurements on an entangled state. Here we discuss the possibility of simulating classically this effect, using classical communication instead of entanglement. We show that infinite communication is necessary for exactly simulating steering for any pure entangled state, as well as for a class of mixed entangled states. Moreover, we discuss the communication cost of steering for general entangled states, as well as approximate simulation. Our findings reveal striking differences between Bell nonlocality and steering, and provide a natural way of measuring the strength of the latter.

description: Recent advances on quantum foundations achieved the derivation of free quantum field theory from general principles, without referring to mechanical notions and relativistic invariance. From the aforementioned principles a quantum cellular automata (QCA) theory follows, whose relativistic limit of small wave-vector provides the free dynamics of quantum field theory. The QCA theory can be regarded as an extended quantum field theory that describes in a unified way all scales ranging from an hypothetical discrete Planck scale up to the usual Fermi scale. The present paper reviews the elementary automaton theory for the Weyl field, and the composite automata for Dirac and Maxwell fields. We then give a simple analysis of the dynamics in the momentum space in terms of a dispersive differential equation for narrowband wave-packets, and some account on the position space description in terms of a discrete path-integral approach. We then review the phenomenology of the free-field automaton and consider possible visible effects arising from the discreteness of the framework. We conclude introducing the consequences of the automaton distorted dispersion relation, leading to a deformed Lorentz covariance and to possible effects on the thermodynamics of ideal gases.

description: Engineered microsystems for in vitro studies of cultured cells are evolving from simple 2D platforms to 3D architectures and organoid cultures. Despite advances in reproducing ever more sophisticated biology in these systems, there remain foundational challenges in re-creating key aspects of tissue composition, architecture, and mechanics that are critical to recapitulating in vivo processes. Against the backdrop of current progress in 3D fabrication methods, we evaluate the key requirements for the next generation of cellular platforms. We postulate that these future platforms – apart from building tissue-like structures – will need to have the ability to readily sense and autonomously modulate tissue responses over time, as occurs in natural microenvironments. Such interactive robotic platforms that report and guide cellular events will enable us to probe a previously inaccessible class of questions in cell biology.

description: We describe a novel method for dynamic estimation of multi-dipole states from Magneto/Electro-encephalography (M/EEG) time series. The new approach builds on the recent development of particle filters for M/EEG; these algorithms approximate, with samples and weights, the posterior distribution of the neural sources at time t given the data up to time t. However, for off-line inference purposes it is preferable to work with the smoothing distribution, i.e. the distribution for the neural sources at time t conditioned on the whole time series. In this study, we use a Monte Carlo algorithm to approximate the smoothing distribution for a time-varying set of current dipoles. We show, using numerical simulations, that the estimates provided by the smoothing distribution are more accurate than those provided by the filtering distribution, particularly at the appearance of the source. We validate the proposed algorithm using an experimental dataset recorded from an epileptic patient. Improved localization of the source onset can be particularly relevant in source modeling of epileptic patients, where the source onset brings information on the epileptogenic zone.

description: Future Internet usage will be dominated by the consumption of a rich variety of online multimedia services accessed from an exponentially growing number of multimedia capable mobile devices. As such, future Internet designs will be challenged to provide solutions that can deliver bandwidth-intensive, delay-sensitive, on-demand video-based services over increasingly crowded, bandwidth-limited wireless access networks. One of the main reasons for the bandwidth stress facing wireless network operators is the difficulty to exploit the multicast nature of the wireless medium when wireless users or access points rarely experience the same channel conditions or access the same content at the same time. In this paper, we present and analyze a novel wireless video delivery paradigm based on the combined use of channel-aware caching and coded multicasting that allows simultaneously serving multiple cache-enabled receivers that may be requesting different content and experiencing different channel conditions. To this end, we reformulate the caching-aided coded multicast problem as a joint source-channel coding problem and design an achievable scheme that preserves the cache-enabled multiplicative throughput gains of the error-free scenario,by guaranteeing per-receiver rates unaffected by the presence of receivers with worse channel conditions.

Can we measure individual black-hole spins from gravitational-wave observations?

description: Measurements of black-hole spins from gravitational-wave observations of black-hole binaries with ground-based detectors are expected to be hampered by partial degeneracies in the gravitational-wave phasing: between the two component spins, and between the spins and the binary's mass ratio, at least for signals that are dominated by the binary's inspiral. Through the merger and ringdown, however, a different set of degeneracies apply. This suggests the possibility that, if the inspiral, merger and ringdown are all within the sensitive frequency band of a detector, we may be able to break these degeneracies and more accurately measure both spins. In this work we investigate our ability to measure individual spins for non-precessing binaries, for a range of configurations and signal strengths, and conclude that in general the spin of the larger black hole will be measurable (at best) with observations from Advanced LIGO and Virgo. This implies that in many applications waveform models parameterized by only one \emph{effective spin} will be sufficient. Our work does not consider precessing binaries or sub-dominant harmonics, although we provide some arguments why we expect that these will not qualitatively change our conclusions.

description: Superconducting QUantum Interference Device (SQUID) metamaterials are superconducting artificial media whose function relies both on their geometry and the extraordinary properties of superconductivity and the Josephson effect. Recent experiments on one- and two-dimensional radio-frequency (rf) SQUID metamaterials have revealed their wide-band tuneability, significantly reduced losses, dynamic multistability, and tunable broadband transparency. The simplest version of an rf SQUID involves a superconducting ring interrupted by a Josephson junction; this device is a highly nonlinear resonator with a strong response to applied magnetic fields. SQUID metamaterials exhibit peculiar magnetic properties such as negative diamagnetic permeability, predicted both for the quantum and the classical regime. The applied alternating fields induce (super)currents in the SQUID rings, which are therefore coupled through dipole-dipole magnetic forces. This interaction is weak due to its magnetic nature. However, it couples the SQUIDs non-locally since it falls-off as the inverse cube of their center-to-center distance.

description: We have developed a search methodology to identify galaxy protoclusters at $z>2.74$, and implemented it on a sample of $\sim$14,000 galaxies with previously measured redshifts. The results of this search are recorded in the Candidate Cluster and Protocluster Catalog (CCPC). The catalog contains 12 clusters that are highly significant overdensities ($δ_{gal}>7$), 6 of which are previously known. We also identify another 31 candidate protoclusters (including 4 previously identified structures) of lower overdensity. CCPC systems vary over a wide range of physical sizes and shapes, from small, compact groups to large, extended, and filamentary collections of galaxies. This variety persists over the range from $z=3.71$ to $z=2.74$. These structures exist as galaxy overdensities ($δ_{gal}$) with a mean value of 2, similar to the values found for other protoclusters in the literature. The median number of galaxies for CCPC systems is 11. Virial mass estimates are large for these redshifts, with thirteen cases apparently having $M > 10^{15}\, M_{\odot}$. If these systems are virialized, such masses would pose a challenge to $Λ$CDM.

description: This study addresses the pressing issue of producing polymer membranes for drinking water purification in light of climate change. Despite years of research, the precise relationship between pore properties and fabrication parameters remains ambiguous. To address this challenge, the study employs machine learning methods to capture complex relationships between variables of quality. The study includes an in-house dataset of 1970 PS-P4VP-copolymer electron microscopy images with pore structures, along with their fabrication parameters. A deep learning model is utilized to generate semantic segmentation masks for extracting morphological membrane parameters from microscopy images. Using these generated segmentations allows the extraction of pore-specific parameters, such as size, as well as general structural characteristics, such as pore coverage and distribution, for all images. A human-in-the-loop active learning approach is used for training the deep learning model, where human expertise is utilized to optimize the model's prediction by iteratively selecting and labeling the most informative data points for the model to learn from. In this way, the labeling is done efficiently and accurately, resulting in a comprehensive database containing the membrane properties. Random forests are employed in regression modeling due to their accuracy and robustness in handling complex and high-dimensional datasets. The models can handle both categorical and continuous input variables and are relatively insensitive to outliers and missing data, making them suitable for such real-world datasets. Additionally, the models provide feature importance measures, allowing the identification of the most influential factors in membrane quality. In parallel to random forests, we used various regression and neural network models to identify the critical parameters that determine the quality of membranes. Our findings from a pipeline of image and tabular data analysis demonstrate precise quality parameter predictions that are in line with experimental findings. The results demonstrate the effectiveness of machine learning in capturing complex relationships between variables for optimizing membrane quality. Overall, this study showcases a comprehensive approach to improving membrane production for drinking water purification, integrating data collection, deep learning, and regression modeling. The approach provides a promising avenue for future research in this area.

description: The Smith Cloud is a gaseous high-velocity cloud (HVC) in an advanced state of accretion, only 2.9 kpc below the Galactic plane and due to impact the disk in 27 Myr. It is unique among HVCs in having a known distance (12.4+/-1.3 kpc) and a well-constrained 3D velocity (296 km/s), but its origin has long remained a mystery. Here we present the first absorption-line measurements of its metallicity, using HST/COS UV spectra of three AGN lying behind the Cloud together with Green Bank Telescope 21 cm spectra of the same directions. Using Voigt-profile fitting of the S II 1250, 1253, 1259 triplet together with ionization corrections derived from photoionization modeling, we derive the sulfur abundance in each direction; a weighted average of the three measurements gives [S/H]=-0.28+/-0.14, or 0.53+0.21-0.15 solar metallicity. The finding that the Smith Cloud is metal-enriched lends support to scenarios where it represents recycled Galactic material rather than the remnant of a dwarf galaxy or accreting intergalactic gas. The metallicity and trajectory of the Cloud are both indicative of an origin in the outer disk. However, its large mass and prograde kinematics remain to be fully explained. If the cloud has accreted cooling gas from the corona during its fountain trajectory, as predicted in recent theoretical work, its current mass would be higher than its launch mass, alleviating the mass concern.

description: Diversity represents a key concept in ecology, and there are various methods of assessing it. The multitude of diversity indices are quite puzzling and sometimes difficult to compute for a large volume of data. This paper promotes a computational tool used to assess the diversity of different entities. The BIODIV software is a user-friendly tool, developed using Microsoft Visual Basic. It is capable to compute several diversity indices such as: Shannon, Simpson, Pielou, Brillouin, Berger-Parker, McIntosh, Margalef, Menhinick and Gleason. The software tool was tested using real data sets and the results were analysed in order to make assumption on the indices behaviour. The results showed a clear segregation of indices in two major groups with similar expressivity.

description: Using the numerical renormalization group (NRG), we analyze the temperature dependence of the spectral function of a magnetic impurity described by the single-impurity Anderson model coupled to superconducting contacts. With increasing temperature the spectral weight is gradually transferred from the $δ$-peak (Shiba/Yu-Shiba-Rusinov/Andreev bound state) to the continuous sub-gap background, but both spectral features coexist at any finite temperature, i.e., the $δ$-peak itself persists to temperatures of order $Δ$. The continuous background is due to inelastic exchange scattering of Bogoliubov quasiparticles off the impurity and it is thermally activated since it requires a finite thermal population of quasiparticles above the gap. In the singlet regime for strong hybridization (charge-fluctuation regime) we detect the presence of an additional sub-gap structure just below the gap edges with thermally activated behavior, but with an activation energy equal to the Shiba state excitation energy. These peaks can be tentatively interpreted as Shiba bound states arising from the scattering of quasiparticles off the thermally excited sub-gap doublet Shiba states, i.e., as high-order Shiba states.

description: Hagen, K.B. v. 2003: SpecRat 1.0, a small computer program to study shifts in speciation rates. Schlechtendalia 10: 67–63.Um Änderungen der Diversifizierungsrate in einem Stammbaum zu untersuchen, sind mehrere zum Teil komplizierte Verfahren in der Literatur beschrieben worden. In dieser Arbeit wird SpecRat 1.0, ein kleines neues Computerprogramm, beschrieben, das auf einer schon länger bekannten Likelihood-Methode beruht. Es ist in C geschrieben und kann leicht für alle Betriebssysteme kompiliert werden. Die Methode, das Programm, Kontrollparameter und graphische Präsentations-möglichkeiten werden erläutert. Am Ende wird die Anwendung des Likelihood-Verhältnistests beschrieben, der mit den erhaltenen Daten manuell ausgeführt werden muss.
description: Hagen, K.B. v. 2003: SpecRat 1.0, a small computer program to study shifts in speciation rates. Schlechtendalia 10: 67–63.Shifts in diversification rates along a phylogenetic tree can be evaluated with a number of different sometimes rather complex methods. Here, the features of SpecRat 1.0, a small new computer program, which incorporates a likelihood method described in the literature some time ago are explained. It iswritten in C and should work with most standard compilers. The idea of the method, its implementation in C, the control features and an output option which can be useful for graphical presentation are outlined. It is also explained how the resulting parameters are used to manually calculate final probabilitiesapplying a likelihood ratio test.

Individual area and spatial distribution of saplings

description: Forest regeneration is a spatial multifaceted process with numerous unknown variables. The individual area or the area potentially available (APA) to an individual plant embodies an idea widely used in population ecology but it has fewer applications in forest research. It was used a Voronoi/ Thiessen tessellation in order to determine the individual area of each sapling. The study was conducted in a naturally regenerated area; using data collected from over seven thousands saplings positioned in a network of permanent rectangular sampling plots. The Voronoi/ Thiessen polygons were used to characterize spatial pattern of sapling distribution as well as the competition relations between the individuals. It is obvious that, at least from the mathematically point of view, the Voronoi tessellation represents one of the best solutions to determine neighbouring competitors of a tree. There were studied the correlations between APA values and the main biometrical attributes, height growth and competition indices. Furthermore, it is shown that APA coefficient of variation is a straight-forward indicator with positive results as an indicator of spatial pattern. The statistical significance of this indicator was evaluated by comparing the results with the values of a 95% confidence envelope generated by Monte-Carlo simulations. Two practical software tools were produced using Visual Basic (VORONOI and ARIA VORONOI) in order to simplify the analyses.

description: Crowdlending has enabled small businesses to borrow capital while lowering transaction costs and improving access to finance. While these trends are promising, little attention has been paid to evaluating and strategizing the trust-building capabilities of the platform for lenders in the information systems literature (IS). Crowdlending platforms rely solely on the information provided by borrowers to evaluate loan requests. Reliance on such information could influence lenders' behavior, investment decisions, and returns. This study aims to develop a more comprehensive model to understand what elements and factors influence trust formation in crowdlending. We develop our model based on social and economic exchanges and technological considerations. Our results suggest that lenders are likely to pay more attention to platform quality and risk mitigation than to the attractive loan features. This research can help the crowdlending industry increase its investor base and make it easier for potential customers to access capital. In addition, these findings could also be beneficial when it comes to establishing regulatory guidelines for the crowdlending market.
Second order kinetic Kohn-Sham lattice model

description: In this work we introduce a new semi-implicit second order correction scheme to the kinetic Kohn-Sham lattice model. The new approach is validated by performing realistic exchange-correlation energy calculations of atoms and dimers of the first two rows of the periodic table finding good agreement with the expected values. Additionally we simulate the ethane molecule where we recover the bond lengths and compare the results with standard methods. Finally, we discuss the current applicability of pseudopotentials within the lattice kinetic Kohn-Sham approach.

description: The Flat Top Cavity, located in the PSI HIPA Ring Cyclotron leaks RF power of several kilo Watts into the cyclotrons vacuum space causing several complications. A detailed electromagnetic model was created and simulations performed to analyze the mechanisms by which power is leaking out of the Flat Top Cavity. The tolerances needed to limit the leaked power in future iterations of the Flat Top cavity are reported. Comparison of the model to measurements are described as well as two potential methods to limit power leakage. These studies will have direct impact on future RF cavity designs for cyclotrons as power levels increase and higher RF fields are required.

description: Στη σύγχρονη κλινική πρακτική, είναι συχνή η αδυναμία αντιμετώπισης πολύπλοκων, πολυπαραγοντικών νόσων μέσω μονοθεραπείας. Μία από τις πιθανές λύσεις τέτοιων καταστάσεων είναι οι Σταθεροί Συνδυασμοί Φαρμάκων (ΣΣΦ). Οι ΣΣΦ μπορεί να προάγουν την αποτελεσματικότητα της θεραπείας, να μειώσουν τις ανεπιθύμητες ενέργειες, να βελτιώσουν την συμμόρφωση των ασθενών στην αγωγή και να αποτρέψουν την λανθασμένη χρήση φαρμακευτικής αγωγής. Ωστόσο, όπως και στην περίπτωση των μονοθεραπειών, οι νέοι ΣΣΦ πρέπει να περάσουν από μια συγκεκριμένη διαδικασία για να λάβουν άδεια κυκλοφορίας. Ο σκοπός της παρούσας εργασίας είναι η περιγραφή της διαδικασίας αδειοδότησης των ΣΣΦ. Συμπερασματικά, μπορούμε να αναφέρουμε ότι το πεδίο ανάπτυξης των ΣΣΦ συνεχίζει να αναπτύσσεται και να παρέχει νέους ΣΣΦ, αποτελούμενους είτε από ουσίες που έχουν εγκριθεί στο παρελθόν, είτε από νέες ουσίες. Εκτός από τις τυπικές κλινικές δοκιμές που ακολουθούνται και στις κλασσικές περιπτώσεις φαρμάκων, χρησιμοποιούνται και τα υπάρχοντα δεδομένα της βιβλιογραφίας, αλλά και νέες μέθοδοι μοντελοποίησης και μελετών έκθεσης-απόκρισης. Ωστόσο, θα πρέπει να παραμετροποιηθούν ανάλογα και οι διαδικασίες αδειοδότησης προκειμένου να προκύπτουν ΣΣΦ που θα προάγουν την ασθενοκεντρική προσέγγιση
description: In recent clinical practice, certain difficulties in the treatment of certain multifactorial and complicated diseases have become obvious. One of the possible solutions to these difficulties are Fixed Dose Combination drugs (FDC). FDC drugs can increase the efficacy of therapy, prevent adverse effects, enhance patient’s adherence to the prescribed treatment and avoid the incorrect use of drugs. However, following a similar process that is used in classic drugs, FDC drugs must receive marketing authorization from relevant authorities before they are marketable. The purpose of the current thesis is the description of the regulatory approval process for FDC drugs. In conclusion, the field of FDC drug development is continuously growing and provides new FDCs containing either substances that have been authorized for market classic therapies, or newly developed pharmacological agents. Besides typical clinical trials that are also followed in classic drug development, literature data, new modelling techniques and exposure-response trials are also used. However, in order to develop new FDC drugs that promote the individualized therapy approach, the procedures to obtain authorization should also be updated
