description: The study of exoplanets and especially their atmospheres can reveal key insights on their evolution by identifying specific atmospheric species. For such atmospheric investigations, high-resolution transmission spectroscopy has shown great success, especially for Jupiter-type planets. Towards the atmospheric characterization of smaller planets, the super-Earth exoplanet 55 Cnc e is one of the most promising terrestrial exoplanets studied to date. Here, we present a high-resolution spectroscopic transit observation of this planet, acquired with the PEPSI instrument at the Large Binocular Telescope. Assuming the presence of Earth-like crust species on the surface of 55 Cnc e, from which a possible silicate-vapor atmosphere could have originated, we search in its transmission spectrum for absorption of various atomic and ionized species such as Fe , Fe+, Ca , Ca+, Mg and K , among others. Not finding absorption for any of the investigated species, we are able to set absorption limits with a median value of 1.9 x RP. In conclusion, we do not find evidence of a widely extended silicate envelope on this super-Earth reaching several planetary radii.

description: A core aim of neurocritical care is to prevent secondary brain injury. Spreading depolarizations (SDs) have been identified as an important independent cause of secondary brain injury. SDs are usually detected using invasive electrocorticography recorded at high sampling frequency. Recent pilot studies suggest a possible utility of scalp electrodes generated electroencephalogram (EEG) for non-invasive SD detection. However, noise and attenuation of EEG signals makes this detection task extremely challenging. Previous methods focus on detecting temporal power change of EEG over a fixed high-density map of scalp electrodes, which is not always clinically feasible. Having a specialized spectrogram as an input to the automatic SD detection model, this study is the first to transform SD identification problem from a detection task on a 1-D time-series wave to a task on a sequential 2-D rendered imaging. This study presented a novel ultra-light-weight multi-modal deep-learning network to fuse EEG spectrogram imaging and temporal power vectors to enhance SD identification accuracy over each single electrode, allowing flexible EEG map and paving the way for SD detection on ultra-low-density EEG with variable electrode positioning. Our proposed model has an ultra-fast processing speed (<0.3 sec). Compared to the conventional methods (2 hours), this is a huge advancement towards early SD detection and to facilitate instant brain injury prognosis. Seeing SDs with a new dimension - frequency on spectrograms, we demonstrated that such additional dimension could improve SD detection accuracy, providing preliminary evidence to support the hypothesis that SDs may show implicit features over the frequency profile.

description: The LiveCode software and scripts in the zipped folder contains the entire experiment. This program implements an experiment to examine the influence of insight moments on brand memory and evaluation. It begins by randomly generating sequences of brand name stimuli paired with anagram, CRA, or no puzzle conditions across trials. On each trial, it presents the brand name and description, then displays the relevant puzzle instructions and interface for participants to solve anagrams or CRAs. During puzzles, the program tracks solving time and accuracy. After puzzles are solved, it prompts participants to rate whether they experienced an insight moment. Next, participants provide ratings on various dimensions of brand evaluation. At the end of the trials, the program conducts a surprise brand name memory test. Throughout the experiment, it handles conditional logic and transitions for moving through different stages of each trial. The program also records participant responses and plays short instructional videos before each new condition to explain the upcoming puzzle type. Finally, it formats the data and saves output files containing full trial information, brand ratings, recall accuracy scores, and other relevant variables for analysis. In summary, this LiveCode program allows the entire experimental procedure to be delivered from stimuli generation to data collection, enabling a robust examination of how insight moments influence brand memory and attitudes.

description: Scene transfer for vision-based mobile robotics applications is a highly relevant and challenging problem. The utility of a robot greatly depends on its ability to perform a task in the real world, outside of a well-controlled lab environment. Existing scene transfer end-to-end policy learning approaches often suffer from poor sample efficiency or limited generalization capabilities, making them unsuitable for mobile robotics applications. This work proposes an adaptive multi-pair contrastive learning strategy for visual representation learning that enables zero-shot scene transfer and real-world deployment. Control policies relying on the embedding are able to operate in unseen environments without the need for finetuning in the deployment environment. We demonstrate the performance of our approach on the task of agile, vision-based quadrotor flight. Extensive simulation and real-world experiments demonstrate that our approach successfully generalizes beyond the training domain and outperforms all baselines.

description: There have been many studies and research that address sustainable drainage urban systems (SUDS), where factors like costs or the zone where a SUDS is to be installed are determinant, so multicriteria studies are important in decision-making. The development of a multidisciplinary approach could in the future serve as a helping tool to support decision, whose purpose would be to guide users in their choice of the most appropriate solution for managing the collection of rainwater. Another key point is to make use of other strategies to accurately define the most appropriate SUDS for a particular location. Modelling for example, considers different factors to simulate real-time rainfall events and evaluate the performance of rainwater collection systems among other low impact development systems. Based on what has been stated above, some successful cases currently performed all over the world were studied, where it is evident that green roofs can retain between 70% and 100% when rainfall is not high and peak reduction on these may reach 83.3%. Concrete and porous asphalt mixtures differ in their behaviour, but even so, they can maintain over time an average permeability between 0.41 cm/s and 0.22 cm/s, and similar values in the reduction of the infiltration capacity of 79.43% and 82.04% respectively.

description: Ransomware attacks have increased significantly in recent years, causing great destruction and damage to critical systems and business operations. Attackers are unfailingly finding innovative ways to bypass detection mechanisms, whichencouraged the adoption of artificial intelligence. However, most research summarizes the general features of AI and induces many false positives, as the behavior of ransomware constantly differs to bypass detection. Focusing on the key indicating features of ransomware becomes vital as this guides the investigator to the inner workings and main function of ransomware itself. By utilizing access privileges in process memory, the main function of the ransomware can be detected more easily and accurately. Furthermore, new signatures and fingerprints of ransomware families can be identified to classify novel ransomware attacks correctly. The current research used the process memory access privileges of the different memory regions of the behavior of an executable to quickly determine its intent before serious harm can occur. To achieve this aim, several well-known machine learning algorithms were explored with an accuracy range of 81.38 to 96.28 percents. The study thus confirms the feasibility of utilizing process memory as a detection mechanism for ransomware.

Role of ionizing background on the non-thermal broadening inferred for the aligned absorbers

Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)

description: Using cosmological hydrodynamical simulations at $z\sim0.5$, we measure the thermal ($b_{t}$) and non-thermal ($b_{nt}$) contribution to the line broadening for the intergalactic absorbers having \OVI\ and \HI\ absorption well aligned in the velocity space. We find that the inferred temperature based on $b_{t}$ correlates strongly with the optical depth-weighted kinetic temperature of the absorbing gas, albeit with a large scatter. We show this scatter comes from the spread in the kinetic temperature of the gas contributing to the absorption and hence depends on the feedback processes and the ionizing UV background (UVB) used in the simulations. We show the distribution of $b_{nt}$ is also affected by both feedback processes and the ionizing UVB. Therefore, $b_{nt}$ derived using aligned absorbers may not be a good probe of sub-grid turbulence. Therefore, $b_{nt}$ derived using aligned absorbers may not be a good discriminator between the effect of microscopic turbulence and UVB. Instead, the distribution of $b_{t}$ and $b_{nt}$ together with the frequency of occurrence of the aligned absorbers can be used to place additional constraints on the parameters of the simulation for a given assumed UVB.

description: Measuring model performance is a key issue for deep learning practitioners. However, we often lack the ability to explain why a specific architecture attains superior predictive accuracy for a given data set. Often, validation accuracy is used as a performance heuristic quantifying how well a network generalizes to unseen data, but it does not capture anything about the information flow in the model. Mutual information can be used as a measure of the quality of internal representations in deep learning models, and the information plane may provide insights into whether the model exploits the available information in the data. The information plane has previously been explored for fully connected neural networks and convolutional architectures. We present an architecture-agnostic method for tracking a network's internal representations during training, which are then used to create the mutual information plane. The method is exemplified for graph-based neural networks fitted on citation data. We compare how the inductive bias introduced in graph-based architectures changes the mutual information plane relative to a fully connected neural network.

description: Semiconductor tunable barrier single-electron pumps can produce output current of hundreds of picoamperes at sub ppm precision, approaching the metrological requirement for the direct implementation of the current standard. Here, we operate a silicon metal-oxide-semiconductor electron pump up to a temperature of 14 K to understand the temperature effect on charge pumping accuracy. The uncertainty of the charge pump is tunnel limited below liquid helium temperature, implying lowering the temperature further does not greatly suppress errors. Hence, highly accurate charge pumps could be confidently achieved in a $^4$He cryogenic system, further promoting utilization of the revised quantum current standard across the national measurement institutes and industries worldwide.

description: We study neural image compression based on the Sparse Visual Representation (SVR), where images are embedded into a discrete latent space spanned by learned visual codebooks. By sharing codebooks with the decoder, the encoder transfers integer codeword indices that are efficient and cross-platform robust, and the decoder retrieves the embedded latent feature using the indices for reconstruction. Previous SVR-based compression lacks effective mechanism for rate-distortion tradeoffs, where one can only pursue either high reconstruction quality or low transmission bitrate. We propose a Masked Adaptive Codebook learning (M-AdaCode) method that applies masks to the latent feature subspace to balance bitrate and reconstruction quality. A set of semantic-class-dependent basis codebooks are learned, which are weighted combined to generate a rich latent feature for high-quality reconstruction. The combining weights are adaptively derived from each input image, providing fidelity information with additional transmission costs. By masking out unimportant weights in the encoder and recovering them in the decoder, we can trade off reconstruction quality for transmission bits, and the masking rate controls the balance between bitrate and distortion. Experiments over the standard JPEG-AI dataset demonstrate the effectiveness of our M-AdaCode approach.

description: Assuming that the anthropogenic impact of visitors to a natural park can be reduced by communication actions, we have drawn up a bioacoustical protocol combined with a protocol to measure the effectiveness of the communication actions. A simple eco-awareness communication method will be compared to a binding communication method. We address the questions: does visitors' eco-awareness drive them to change their attitudes and behavior in order to limit their own noise disturbance, and does commitment improve their awareness? We detail here the main concepts considered and the methodology followed to discuss the preliminary results.

description: In the paper we consider a stochastic model which called Markov Q-processes that forms a continuous-time Markov population system. Markov Q-processes are defined as stochastic Markov branching processes with trajectories continuing in the remote future. Estimation of the structural parameter of the Markov Q-process is the main goal of this paper. To estimate this parameter, an unbiased estimator of the Lotka-Nagaev type is proposed. An asymptotic expansion of the variance of this estimator is found.

description: The main objective of a statistical mechanical calculation is drawing the phase diagram of a many-body system. In this respect, discrete systems offer the clear advantage over continuum systems of an easier enumeration of microstates, though at the cost of added abstraction. With this in mind, we examine a system of particles living on the vertices of the (biscribed) pentakis dodecahedron, using different couplings for first and second neighbor particles to induce a competition between icosahedral and dodecahedral orders. After working out the phases of the model at zero temperature, we carry out Metropolis Monte Carlo simulations at finite temperature, highlighting the existence of smooth transitions between distinct "phases", The sharpest of these crossovers are characterized by hysteretic behavior near zero temperature, which reveals a bottleneck issue for Metropolis dynamics in state space. Next, we introduce the quantum (Bose-Hubbard) counterpart of the previous model and calculate its phase diagram at zero and finite temperatures using the decoupling approximation. We thus uncover, in addition to Mott insulating "solids", also the existence of supersolid "phases" which progressively shrink as the system is heated up. We argue that a quantum system of the kind described here can be realized with programmable holographic optical tweezers.

description: Since the opening of the Bibliotheca Alexandrina in October 2002, the library has become one of the most important places for learning and research in the Middle East. Signs for the success are the number of media units (appr. 800.000), patrons (appr. 15.000), staff (appr. 2.000), training programmes (about 800 per year) and the quality of international conferences. Despite the high standard of architecture and technical equipment, in this paper problems of the aquisition unit, the standard of eaducation and the information policy in Egypt are discussed.

Der Erfolg der Bibliothek lässt sich u. a. an den Beständen (ca. 800.000 Medieneinheiten), der Zahl von Nutzerinnen und Nutzern (ca. 15.000), Mitarbeiterinnen und Mitarbeitern (ca. 2.000), Fortbildungsveranstaltungen (jährlich ca. 800) und der Qualität der internationalen Konferenzen ablesen. Trotz der guten räumlichen und technischen Ausstattung sind hingegen auch bestehende Probleme, etwa in den Bereichen Bestandsaufbau und Vermittlung von Informationskompetenz, nicht zu übersehen, die in den sich in Entwicklung befindlichen politischen, sozialen und kulturellen Rahmenbedingungen in Ägypten ihre Ursache haben. Der vorliegende Bericht beruht auf zwei Aufenthalten an der Bibliotheca Alexandrina in den Jahren 2006 und 2009, die mit Unterstützung des Network of Research Centres in Human Sciences on the Mediterranean Area (RAMSES II) bzw. von BI International durchgeführt wurden.

description: We reconsider model II of [J. Chem. Phys. 1968, 49, 1778--1783], a two-dimensional lattice-gas system featuring a crystalline phase and two distinct fluid phases (liquid and vapor). In this system, a particle prevents other particles from occupying sites up to third neighbors on the square lattice, while attracting (with decreasing strength) particles sitting at fourth- or fifth-neighbor sites. To make the model more realistic, we assume a finite repulsion at third-neighbor distance, with the result that a second crystalline phase appears at higher pressures. However, the similarity with real-world substances is only partial: on closer inspection the alleged liquid-vapor transition turns out to be a continuous (albeit sharp) crossover, even near the putative triple point. Closer to the standard picture is instead the freezing transition, as we show by computing the free-energy barrier to crystal nucleation from the "liquid".

Recently, anomalous magnetic-flux trapping in a Sn45-Pb55 solder has been revealed where the magnetic fluxes are selectively trapped in the Sn regions due to the supercurrents in the surrounding Pb regions. Here, we report on the observation of the anomalous critical field (Hc)-temperature (T) phase diagram of superconductivity in the Sn45-Pb55 solder. Although the Hc(T) for the Pb regions decreases with increasing field as in normal type-I superconductors and is consistent with the conventional trend with Hc(0) ~ 800 Oe, the Hc(T) for the Sn regions exhibits anomalous behaviors. The most noticeable trend was observed in the field-cooled (under 1500 Oe) solder. The Hc-T phase diagram for the Sn regions largely varies when the applied external field is reversed, and Tc increases with increasing field amplitude when H < 0 Oe is applied. On the basis of the flux trapping and the observed anomalous Hc-T phase diagrams, we propose that the field-robust superconductivity in the Sn regions is related to the ferromagnetically-aligned magnetic fluxes (or formation of vortices) in the Sn regions of the Sn45-Pb55 solder.

description: We present a no-go theorem for the distinguishability between quantum random numbers (i.e., random numbers generated quantum mechanically) and pseudo-random numbers (i.e., random numbers generated algorithmically). The theorem states that one cannot distinguish these two types of random numbers if the quantum random numbers are efficiently classically simulatable and the randomness measure used for the distinction is efficiently computable. We derive this theorem by using the properties of cryptographic pseudo-random number generators, which are believed to exist in the field of cryptography. Our theorem is found to be consistent with the analyses on the actual data of quantum random numbers generated by the IBM Quantum and also those obtained in the Innsbruck experiment for the Bell test, where the degrees of randomness of these two set of quantum random numbers turn out to be essentially indistinguishable from those of the corresponding pseudo-random numbers. Previous observations on the algorithmic randomness of quantum random numbers are also discussed and reinterpreted in terms of our theorems and data analyses.

description: Der Begriff Bibliothek 2.0 (bzw. Library 2.0) lehnt sich an die Begrifflichkeit des Web 2.0 an. Beide Begriffe sind für die bibliothekarische Welt relativ neu und werden bisher hauptsächlich im angloamerikanischen Raum diskutiert. Einige Bereiche des „neuen“ Webs werden auch in Deutschland von Bibliothekaren diskutiert, so beispielsweise Weblogs und die Wikipedia. Die Betrachtung sollte hier jedoch nicht enden, sondern vielmehr als Startpunkt dienen. Über den Begriff als solchen kann man sicherlich streiten, jedoch hat er sich als tauglich erwiesen, um bestimmte Veränderungen zu beschreiben. So schreibt Michael Stephens, der den Begriff entscheidend mitprägte, im ALA TechSource Weblog: „I am so pleased with the discussion – and no matter what name you use, I love that the innovations and plans just keep rolling on.“

description: Seit Beginn der 2000er Jahre haben Open Access und Open Content in der global vernetzten Informationswelt sprunghaft an Bedeutung gewonnen. Die Verfügbarkeit von Wissen ist zu einem entscheidenden Entwicklungsfaktor für Wissenschaft, Wirtschaft, Kultur und Gesellschaft geworden. Angesichts der wachsenden Bedeutung stellen sich Fragen der Verfügbarkeit sowie der Teilhabe auf regionaler, nationaler und globaler Ebene. Der freie Zugang zu Wissen erhöht nachweislich dessen Sichtbarkeit. Er ist Voraussetzung für technische Erschließungsverfahren und eröffnet neue Möglichkeiten der Auffindbarkeit und automatisierten Verknüpfung. Aus wissenspolitischer Perspektive trägt Open Access dazu bei, die drohende Kluft zwischen öffentlich geförderten Informationseinrichtungen in regionalen und nationalen Informationsverbünden zu verringern, zudem ermöglicht Open Access strukturell unterentwickelten Regionen, am wissenschaftlichen und wirtschaftlichen Fortschritt teilzuhaben. Formelle Unterstützung findet Open Access durch führende Wissenschafts- und Fördereinrichtungen wie beispielsweise die Deutsche Forschungsgemeinschaft, die Europäische Kommission sowie den Weltverband der Bibliotheken IFLA. Im wissenschaftlichen Bereich wird Open Access in Forschungseinrichtungen in den USA, Großbritannien und der Schweiz durch sog. Mandatories (i. e. rechtsverbindliche Verpflichtungen) getragen, die von ihren Wissenschaftlern die Publikation unter Open-Access-Bedingungen einfordern. Hierbei gibt es jedoch erhebliche nationale Unterschiede, die auf verschiedenen Rechtssystemen und Publikationstraditionen gründen. Der Fokus dieses Beitrags ist darauf gerichtet, wie Wissenschaftliche und Öffentliche Bibliotheken Open Access, Open Content und gemeinfreies Kulturerbe erwerben, bereitstellen, in ihre vorhandenen digitalen Systeme einbinden und unterstützen können. Die Möglichkeiten zukünftiger Tätigkeitsfelder sind hier vielfältig, die Diskussion darüber steht gerade in Deutschland erst am Anfang.
Rare tau decays via exchange of on-shell almost degenerate Majorana neutrinos, $τ^{\mp} \to π^{\mp} N_j \to π^{\mp} μ^{\mp} π^{\pm}$ and $τ^{\mp} \to π^{\mp} N_j \to π^{\mp} μ^{\pm} π^{\mp}$

description: We investigate rare decays of tau leptons that occur via exchange of heavy on-shell neutrinos $N_j$ ($j=1,2$). These neutrinos can be either Dirac or Majorana, and are considered to be almost degenerate in mass. The decays can thus be either lepton number conserving (LNC), $τ^{\mp} \to π^{\mp} N_j \to π^{\mp} μ^{\mp} π^{\pm}$, or lepton number violating (LNV), $τ^{\mp} \to π^{\mp} N_j \to π^{\mp} μ^{\pm} π^{\mp}$. If neutrinos are Dirac, only LNC decays are possible. If they are Majorana, both LNC and LNV are possible. We derive the corresponding expressions for the effective decay widths $Γ_{{\rm eff},\mp}^{\rm (X)}$ (X=LNC, LNV) of these rare decays, where we account for $N_1$-$N_2$ overlap and oscillation effects and for the finite detector length effects. We then numerically evaluate these decay widths as well as the related CP violation asymmetry width $ΔΓ_{\rm CP}^{\rm (X)} = (Γ_{{\rm eff},-}^{\rm (X)} - Γ_{{\rm eff},+}^{\rm (X)})$. We conclude that for certain, presently allowed, ranges of the heavy-light neutrino mixing parameters, such decays and asymmetries could be observed in Belle II experiment.

description: Improving the knowledge about the distribution of threatened species is a fundamental step forward for implementing effective measures for species conservation. Distribution maps of herpetological species are often inferred from morphological identification but, in some cases, morphology alone is not reliable for assessing the distribution of lookalike species. The common lizard Zootoca vivipara includes several lineages which, to date, cannot be distinguished by any conventional morphological traits. Therefore, a reliable taxonomic identification for the main Zootoca lineages is only feasible with genetic data. In this study, we identify a morphological trait that can be used to distinguish individuals of the parapatric Z. v. vivipara and Z. carniolica, without the support of molecular analyses. This method may provide a cost-effective tool to better depict the distribution of the threatened Z. carniolica and therefore prioritize the conservation of the locations where the oviparous Alpine lineage is found.

description: Conventional photoemission orbital tomography based on Fourier iterative method enables us to extract a projected two-dimensional (2D) molecular orbital from a 2D photoelectron momentum map (PMM) of planar $π$-conjugated molecules in a single-orientation system, while not in a multi-orientation system. In this work, we demonstrate photoemission orbital tomography for $π$-conjugated molecules with a tight-binding ansatz (linear combination of atomic orbitals). We analyze 2D PMMs of single-orientation pentacene/Ag(110) and multi-orientation 3,4,9,10-perylenetetracarboxylic dianhydride/Ag(110) and reproduce their three-dimensional highest occupied molecular orbitals. We demonstrate that the PhaseLift algorithm can be used to analyze PMM including experimental or theoretical uncertainties. With the 2D PMM for pentacene, we simultaneously optimized the structure and the molecular orbital. The present approach enables us to extract the three-dimensional orbitals and structures of existing materials.

description: A two-dimensional optical-phased array is demonstrated by using a multiple-input star coupler, compatible with FMCW LiDAR. Previous approach using a single-input design achieves two-dimensional beam-steering by relying on a tunable laser source, taking advantage of grating coupler radiation angle wavelength dependance and variation of the waveguide refractive index. While implementing a convenient way to distribute power in a single step, star coupler architecture is inefficient in terms of employed waveguide length and thus, optical loss and footprint. Multi-input approach partially alleviates this by condensing several single-input devices into one, permitting to reduce the footprint proportionally to the employed number of inputs. We fabricated in silicon nitride technology a proof of concept steerer with beam waist 0.36 deg x 0.175 deg addressing a field of view of 15 deg x 2.8 deg. A new design iteration is also reported with and 0.24 deg x 0.16 deg beam waist and 15 deg x 11.2 deg field of view. Implications of this optical-phased array chips from a LiDAR system perspective are also presented.
