description: We discuss the constraints set on galaxy evolution by data from deep surveys performed in the mid-IR and far-IR with ISO and with mm telescopes at longer wavelengths. These reveal extremely high rates of evolution for IR galaxies. According to our model, the deep ISO surveys at 15 micron may have already resolved more than 50% of the CIRB intensity, hence allowing to investigate the origin of the CIRB. From our fits to the observed optical-IR SEDs, these objects appear to involve massive galaxies hosting luminous starbursts (SFR 100 Mo/yr). Our evolutionary scheme considers a bimodal star formation (SF), including long-lived quiescent SF, and enhanced SF taking place during transient events recurrently triggered by interactions and merging. We interpret the strong observed evolution as an increase with z of the rate of interactions between galaxies (density evolution) and an increase of their IR luminosity due to the more abundant fuel available in the past (luminosity evolution). Very schematically, we associate the origin of the bulk of the optical/NIR background to the quiescent evolution, while the CIRB is interpreted as mostly due the dusty starburst phase (the latter possibly leading to the formation of galaxy spheroids). The large energy contents in the CIRB and optical backgrounds are not easily explained, considering the moderate efficiency of energy generation by stars: a top-heavy stellar IMF associated with the starburst phase (and compared with a more standard IMF during the quiescent SF) would alleviate the problem. IR data suggest that the strong observed evolution to z~1 should turn over at higher z: scenarios in which a dominant fraction of stellar formation occurs at very high-z are not supported by our analysis.

description: In der IT-Forensik nehmen Thumbnails und Cache-Dateien als Beweismittel eine wichtige Rolle ein. Dies liegt insbesondere an ihrer Eigenschaft, automatisch generiert und temporär gespeichert zu werden. Dieser Artikel betrachtet die Verwendbarkeit dieser Datentypen in gerichtlichen Verfahren. Dabei werden die technischen Hintergründe sowie die forensischen Techniken zur Sicherung und Auswertung von Beweisen erläutert. Es ist essenziell für Ermittler, eine klare Unterscheidung zwischen Thumbnails und Cache-Dateien treffen zu können, da beide oft verschiedene Auskünfte über die Herkunft und Nutzung der Daten geben. Thumbnails sind in der Regel verkleinerte Ansichten von Bildern, während Cache-Dateien häufig Kopien von Webseiten oder anderen Medien beinhalten, die zur Beschleunigung des Zugriffs abgelegt werden. Diese Differenzierung gewinnt insbesondere bei Fragen zur Herkunft und zum Kontext der Daten an Bedeutung. Das Ziel ist es, die Bedeutung von Thumbnails und Cache-Dateien in der täglichen Fallarbeit zu erläutern, ihre Unterscheidbarkeit darzustellen und ihren Beitrag zur Beweisführung hervorzuheben.

description: Automated content detection systems have become a powerful tool for quickly categorizing infringing content, as online platform providers have gradually taken a more active role in moderating speech. Thus, the decision-making structure of the Meta’s Oversight Board (hereinafter “the Board”) was chosen as the subject of this study, based on the selection of 29 case decisions and policy opinions (both of which are hereinafter collectively referred to as “cases”) published by the Board until March 31st, 2024, involving automated content moderation systems. Based on the data collected, the following research problem arises: how can the Board’s decision-making structure contribute to illustrate how platforms have been tracing new limits to freedom of expression using automated content detection to identify infringing content? The research is guided by the inductive research method, since it analyzes a sample of Oversight Board decisions to make broader assumptions.

description: We have identified a star, EPIC 249706694 (HD 139139), that was observed during K2 Campaign 15 with the Kepler extended mission that appears to exhibit 28 transit-like events over the course of the 87-day observation. The unusual aspect of these dips, all but two of which have depths of $200 \pm 80$ ppm, is that they exhibit no periodicity, and their arrival times could just as well have been produced by a random number generator. We show that no more than four of the events can be part of a periodic sequence. We have done a number of data quality tests to ascertain that these dips are of astrophysical origin, and while we cannot be absolutely certain that this is so, they have all the hallmarks of astrophysical variability on one of two possible host stars (a likely bound pair) in the photometric aperture. We explore a number of ideas for the origin of these dips, including actual planet transits due to multiple or dust emitting planets, anomalously large TTVs, S- and P-type transits in binary systems, a collection of dust-emitting asteroids, `dipper-star' activity, and short-lived starspots. All transit scenarios that we have been able to conjure up appear to fail, while the intrinsic stellar variability hypothesis would be novel and untested.

description: Tangible historical and cultural assets refer to physical artifacts that can be touched and intergenerationally transferred. This kind of asset is considered the past that the next generations should memorize. One of the issues that archaeologists frequently face is the methods used in digitally restoring disappeared archaeological assets. This is due to their low quality, noisy texture, or uncolored images. On the other hand, the advent of new technologies such as digital image processing (DIP) and virtual reality (VR) makes it palatable to digitalize and sustain tangible historical assets. These technologies are recognized as efficient tools insofar as they can contribute to preserving the heritage of civilizations. Hence, this study suggests an approach that integrates DIP and VR techniques to restore historical assets that have disappeared from low-quality images. The findings show that the proposed methodology is successful in restoring archaeological sites or objects, as demonstrated by the results obtained.
X-ray Binaries and Globular Clusters in Elliptical Galaxies

description: The X-ray emission from normal elliptical galaxies has two major components: soft emission from diffuse gas and harder emission from populations of accreting (low-mass) stellar X-ray binaries (LMXB). If LMXB populations are tied to the field stellar populations in galaxies, their total X-ray luminosities should be proportional to the optical luminosities of galaxies. However, recent ASCA and Chandra X-ray observations show that the global luminosities of LMXB components in ellipticals exhibit significant scatter at a given optical luminosity. This scatter may reflect a range of evolutionary stages among LMXB populations in ellipticals of different ages. If so, the ratio of the global LMXB X-ray luminosity to the galactic optical luminosity, L_LMXB/L_opt, may be used to determine when the bulk of stars were formed in individual ellipticals. To test this, we compare variations in L_LMXB/L_opt for LMXB populations in ellipticals to optically-derived estimates of stellar ages in the same galaxies. We find no correlation, implying that L_LMXB/L_opt variations are not good age indicators for ellipticals. Alternatively, LMXBs may be formed primarily in globular clusters (through stellar tidal interactions), rather than in the stellar fields of galaxies. Since elliptical galaxies exhibit a wide range of globular cluster populations for a given galaxian luminosity, this may induce a dispersion in the LMXB populations of ellipticals with similar optical luminosities. Indeed, we find that L_LMXB/L_opt ratios for LMXB populations are strongly correlated with the specific globular cluster frequencies in elliptical galaxies. This suggests that most LMXBs were formed in globular clusters.

Fluxon interaction with the finite-size dipole impurity

description: Interaction of the fluxon with the finite size dipole impurity in the long Josephson junction is investigated. The impurity has polarity and will be referred to as a {\it dipole} impurity because it also has a direction and, consequently, changes its sign under the space inversion transform $x \to -x$. Such a model is used to describe the inductively coupled to the Josephson transmission line qubit and the misaligned Abrikosov vortex that penetrates into the long Josephson junction. We derive the approximate equations of motion for the fluxon center of mass and its velocity. With the help of these equations we demonstrate that pinning and scattering of the fluxon on the impurity differs significantly from the case of the point impurity which is modelled by the derivative of the Dirac's $δ$-function

description: Analyzing video footage can make an important contribution to solving crimes, but it is often limited by challenges such as hidden faces. Modern methods of the digital age rely on anthropometric measurements to overcome these limitations. However, current techniques, often originating from other sectors such as the gaming industry, offer new potential. In this context, a possible new approach based on the application of 3D human pose estimation will be presented. This would offer the possibility of directly matching two people (perpetrator, suspect) using one video of each. In particular, this new approach would significantly reduce the scope of the necessary work steps and the time required. This also applies in comparison to methods that already use 2D position estimation. The new approach presented here could contribute to a significant increase in forensic efficiency if successfully implemented after testing and evaluation on a study dataset and real case data.

Microlensing planets in M22: free-floating or bound?

Subjects: subject: Astrophysics (astro-ph)

description: We use detailed numerical simulations and theoretical estimates to show that, if confirmed, the unusually brief microlensing events observed by Sahu et al. (2001) in the field of the globular cluster M22 might be explained as a result of microlensing by a population of clustered MACHOs, a dark cluster or RAMBO, not associated with the globular cluster. If real, this dark cluster would be located between M22 and the Galactic bulge and could include at least $10^6$ substellar members with a typical size of 1-3 pc. Bound planets in wide or/and eccentric orbits are also able to reproduce the observed microlensing behaviour, but only if multiplanet systems (including large Kuiper-belt-like objects) are abundant, although, our calculations argue against the latter scenario as the ionization rate in M22 is very high. Dynamically ejected or lone planets are, in principle, incompatible with the observational findings as they either escape their parent cluster in a relatively short time-scale after ejection or segregate toward the outskirts of the cluster. We discuss additional implications of the dark cluster scenario, including the existence of a population of RAMBOs toward the Galactic bulge.

(Figs. 23–25)
 (Syns.: Astiotrema fusiformis [Wang, 1981] n. comb.; Gauhatiana fusiformis Wang, 1981 n. syn.)
 Records (see Table 1): 1. Dhar (1977); 2. Wang (1981).
 Remarks: Dhar (1977) described A. fotedari for specimens obtained from the large intestine of the kalabans, Bangana dero (Hamilton) (Syn. Labeo dero [Hamilton]) (Cypriniformes: Cyprinidae), from Poonch in the state of Jammu and Kashmir (currently divided between India and Pakistan). Astiotrema reniferum represents the most closely related species morphologically to A. fotedari except that the former has a more restricted distribution of the vitellarium (from the level of the ventral sucker to the posterior limit of the posterior testis) and a longer esophagus while A. fotedari parasitizes a different host group (Cyprinidae) (see Dhar 1977). Wang (1981) described G. fusiformis from the intestine of the yellowfin, Xenocypris macrolepis Bleeker (Syn. Xenocypris argentea Günther) (Cypriniformes: Cyprinidae), from Fujian Province, China. We found the morphological characters of G. fusiformis to be identical to those of species of Astiotrema, while G. fusiformis differs from species of Gauhatiana particularly in lacking vitellarium in two clusters within the lateral fields and an equatorial ovary (see Gupta 1953; Wang 1981; Font & Lotz 2008); thereby, we reassign it within Astiotrema as A. fusiformis n. comb. Within a comparison with representative species of Astiotrema, we recognized that A. fusiformis has the same overall morphology and host group (Cyprinidae) as A. fotedari, though we note the slightly longer posterior extent of the cirrus-pouch relative to the posterior margin of the ovary in A. fusiformis. Consequently, A. fusiformis is herein considered a synonym of A. fotedari .
 Astiotrema fotedari has the following uniquely-combined features: (i) oral sucker larger than ventral one, (ii) vitelline fields long, extending anteriorly either to the level of the intestinal bifurcation or to pharyngeal level and posteriorly either to the blind ends of the ceca or slightly further posterior, (iii) ceca long, terminating a little anterior to the posterior extremity, and (iv) ovary closer to the ventral sucker than it is to anterior testis.

description: Reverberation mapping (RM) is a powerful approach for determining the nature of the broad-line region (BLR) in active galactic nuclei. However, inferring physical BLR properties from an observed spectroscopic time series is a difficult inverse problem. Here, we present a blind test of two widely used RM methods: MEMEcho (developed by Horne) and CARAMEL (developed by Pancoast and collaborators). The test data are simulated spectroscopic time series that track the H$α$ emission line response to an empirical continuum light curve. The underlying BLR model is a rotating, biconical accretion disc wind, and the synthetic spectra are generated via self-consistent ionization and radiative transfer simulations. We generate two mock data sets, representing Seyfert galaxies and QSOs. The Seyfert model produces a largely *negative* response, which neither method can recover. However, both fail $``gracefully''$, neither generating spurious results. For the QSO model both CARAMEL and expert interpretation of MEMEcho's output both capture the broadly annular, rotation-dominated nature of the line-forming region, though MEMEcho analysis overestimates its size by 50%, but CARAMEL is unable to distinguish between additional inflow and outflow components. Despite fitting individual spectra well, the CARAMEL velocity-delay maps and RMS line profiles are strongly inconsistent with the input data. Finally, since the H$α$ line-forming region is rotation dominated, neither method recovers the disc wind nature of the underlying BLR model. Thus considerable care is required when interpreting the results of RM analyses in terms of physical models.

description: Van der Waals (vdW) ferromagnetic materials are rapidly establishing themselves as effective building blocks for next generation spintronic devices. When layered with non-magnetic vdW materials, such as graphene and/or topological insulators, vdW heterostructures can be assembled (with no requirement for lattice matching) to provide otherwise unattainable device structures and functionalities. We report a hitherto rarely seen antisymmetric magnetoresistance (MR) effect in van der Waals heterostructured Fe3GeTe2/graphite/Fe3GeTe2 devices. Unlike conventional giant magnetoresistance (GMR) which is characterized by two resistance states, the MR in these vdW heterostructures features distinct high, intermediate and low resistance states. This unique characteristic is suggestive of underlying physical mechanisms that differ from those observed before. After theoretical calculations, the three resistance behavior was attributed to a spin momentum locking induced spin polarized current at the graphite/FGT interface. Our work reveals that ferromagnetic heterostructures assembled from vdW materials can exhibit substantially different properties to those exhibited by similar heterostructures grown in vacuum. Hence, it highlights the potential for new physics and new spintronic applications to be discovered using vdW heterostructures.

description: X platform (previously Twitter) produces massive amounts of data related to all aspects of our daily life. Such data can be utilized for archiving interesting information that can be extracted from this data. Since the field of cultural heritage is one of the crucial aspects that a huge number of posts focus on, the daily updates obtained from X have made it possible to record all related posts to the cultural heritage in a comprehensive and real-time way. This data can contribute to the important process of archiving and digitizing the cultural heritage of the ancient community, which is a significant part of its conservation and preservation. This paper is designed to implement a container-based cloud framework for real-time collection and archiving of posts related to the cultural heritage of Nineveh. The framework is designed to manage various types of X data, including images, text data, and video. All collected data is taken from the social media server to the cloud storage.

description: Educational pathways play a pivotal role in fostering lifelong learning and skilled workforces. We build upon a German labor market knowledge graph that was developed from the German Labor Market Ontology (GLMO). The GLMO provides entities for qualifications, such as occupations and training programs, as well as tools and skills. To conduct research on educational pathways, we employ several graph algorithms, such as shortest paths, and present the results. It is possible to demonstrate the advantages of digital methods in sociological research, thereby advancing the boundaries of computational social sciences in labor market research.

description: We have studied the effect of a non-Hermitian Bosonic bath on the dynamics of a two-level spin system. The non-Hermitian Hamiltonian of the bath is chosen such that it converges to the harmonic oscillator Hamiltonian when the non-Hermiticity is switched off. We calculate the dynamics of the spin system and found that the non-Hermiticity can have positive as well as negative effects on the coherence of the system. However, the decoherence can be completely eliminated by choosing the non-Hermiticity parameter and the phase of the system bath interaction appropriately. We have also studied the effect of this bath on the entanglement of a two-spin system when the bath is acting only on one spin.

description: With the growing complexity of cyber-physical systems (CPS), adaptive and robust monitoring solutions are increasingly crucial for ensuring operational reliability and safety. Anomaly detection is a critical component of monitoring systems, particularly in dynamic environments such as water management systems, where operational regimes can vary significantly over time. Traditional static thresholding techniques, which use a single fixed threshold for the entire monitoring process, are often inadequate due to their inability to adapt to changing data patterns, leading to high rates of false positives and missed detections. This paper explores the limitations of static thresholding and presents a comparative analysis with more adaptive approaches. We first discuss the use of static thresholds for each regime shift, which provides some improvement but still falls short in accommodating gradual or unexpected changes. Subsequently, we introduce a dynamic thresholding method based on the Autoregressive Integrated Moving Average (ARIMA) model. This approach continuously adjusts thresholds in real time, effectively accounting for evolving data patterns and regime shifts. Our evaluation, conducted on synthetic water level data with known anomalies, demonstrates that dynamic thresholding significantly outperforms static methods. Specifically, dynamic thresholding achieves an accuracy of 99%, precision of 78%, recall of 88%, and an F1-score of 82%, highlighting its robustness and adaptability. These results underscore the potential of dynamic thresholding techniques to enhance anomaly detection in complex, variable environments.
A framework for sequential measurements and general Jarzynski equations

description: We formulate a statistical model of two sequential measurements and prove a so-called J-equation that leads to various diversifications of the well-known Jarzynski equation including the Crooks dissipation theorem. Moreover, the J-equation entails formulations of the Second Law going back to Wolfgang Pauli. We illustrate this by an analytically solvable example of sequential discrete position-momentum measurements accompanied with the increase of Shannon entropy. The standard form of the J-equation extends the domain of applications of the quantum Jarzynski equation in two respects: It includes systems that are initially only in local equilibrium and it extends this equation to the cases where the local equilibrium is described by microcanononical, canonical or grand canonical ensembles. Moreover, the case of a periodically driven quantum system in thermal contact with a heat bath is shown to be covered by the theory presented here. Finally, we shortly consider the generalized Jarzynski equation in classical statistical mechanics.

description: We study the long-time behaviour and the spatial correlations of a simple ferromagnetic spin system whose kinetics is governed by a thermal bath with a time-dependent temperature which is characterized by a given external relaxation time tau. Exact results are obtained in the framework of the spherical model in d dimensions. In the paramagnetic phase, the long-time kinetics is shown to depend crucially on the ratio between tau and the internal equilibration time tau_eq. If tau is less than tau_eq, the model relaxes rapidly towards an equilibrium state but there appear transient and spatially oscillating contributions in the spin-spin correlation function. On the other hand, if tau is much greater than tau_eq the system is clamped and its time evolution is delayed with respect to the one of the heat bath. For waiting times s such that tau << s << tau_eq, a quasi-stationary state is found where the fluctuation-dissipation theorem does not hold.

description: Pseudomonas cannabina pv. alisalensis (Pcal), which causes bacterial blight disease of Brassicaceae, is an economically important pathogen worldwide. To identify Pcal genes involved in pathogenesis, we conducted a screen for 1040 individual Pcal KB211 Tn5 mutants with reduced virulence on cabbage plants using a dip-inoculation method. We isolated 53 reduced virulence mutants and identified several potential virulence factors involved in Pcal virulence mechanisms such as the type III secretion system, membrane transporters, transcription factors, and amino acid metabolism. Importantly, Pcal is pathogenic on a range of monocotyledonous and dicotyledonous plants. Therefore, we also carried out the inoculation test on oat plants, which are cultivated after cabbage cultivation as green manure crops. Interestingly among the 53 mutants, 31 mutants also exhibited reduced virulence on oat seedlings, indicating that Pcal optimizes its virulence factors for pathogenicity on different host plants. Our results highlight the importance of revealing the virulence factors for each plant host-bacterial interaction, and will provide new insights into Pcal virulence mechanisms.

description: In this Paper we investigate the kinematical properties of early-type dwarfs by significantly enlarging the scarce observational sample so far available. We present rotation curves and mean velocity dispersions for four bright dwarf ellipticals and two dwarf lenticular galaxies in the Virgo cluster. Most of these galaxies exhibit conspicuous rotation curves. In particular, five out of the six new galaxies are found to be close to the predictions for oblate spheroids flattened by rotation. Therefore, and contrary to the previous observational hints, the present data suggest that an important fraction of dwarf early-type galaxies may be rotationally supported.

description: We present techniques to model and design membrane phononic crystals with low-mass defects, optimized for force sensing. Further, we identify the importance of the phononic crystal mass contrast as it pertains to the size of acoustic bandgaps and to the dissipation properties of defect modes. In particular, we quantify the tradeoff between high mass contrast phononic crystals with their associated robust acoustic isolation, and a reduction of soft clamping of the defect mode. We fabricate a set of phononic crystals with a variety of defect geometries out of high stress stoichiometric silicon nitride membranes, and measured at both room temperature and 4 K in order to characterize the dissipative pathways across a variety of geometries. Analysis of these devices highlights a number of design principles integral to the implementation of low-mass, low-dissipation mechanical modes into optomechanical systems.

description: Quantum literacy may be defined as an ability to understand how quantum technologies are used as well as a capability to assess various claims made about quantum computing such as quantum supremacy with minimum knowledge of quantum mechanics [Ni23]. As is argued in [BV10], we also believe that in order to understand the basic ideas about quantum computing, it is not necessary to have solid background in quantum physics. Instead, it is possible to become quantum literate if important differences between classical computing and quantum computing are clearly understood. In this paper, we report our ongoing project that aims to introduce quantum computing to novices. More specifically, based on our experiences of teaching quantum computing at a middle school and a university [Ki23; Le23] we found that students had difficulty in understanding entanglement and we propose a simple, yet nontrivial example which illustrates how entanglement serves as a computing resource that can cut down the number of steps to compute a certain problem. The example is an adaptation of the approach introduced in [Hu18] and we designed a sequence of steps to introduce entanglement to students so that they can understand a subtle issue such as linking two parts of quantum states in such a way that the information in one part is associated with that of the other part in a useful way [Br01].
