description: Synthesis of digital artifacts conditioned on user prompts has become an important paradigm facilitating an explosion of use cases with generative AI. However, such models often fail to connect the generated outputs and desired target concepts/preferences implied by the prompts. Current research addressing this limitation has largely focused on enhancing the prompts before output generation or improving the model's performance up front. In contrast, this paper conceptualizes prompt evolution, imparting evolutionary selection pressure and variation during the generative process to produce multiple outputs that satisfy the target concepts/preferences better. We propose a multi-objective instantiation of this broader idea that uses a multi-label image classifier-guided approach. The predicted labels from the classifiers serve as multiple objectives to optimize, with the aim of producing diversified images that meet user preferences. A novelty of our evolutionary algorithm is that the pre-trained generative model gives us implicit mutation operations, leveraging the model's stochastic generative capability to automate the creation of Pareto-optimized images more faithful to user preferences.

description: Polymers with electrically charged internal air cavities (ferroelectrets) reveal a pronounced piezoelectric response and are regarded as soft electroactive multi-functional materials. This work presents preliminary results on the preparation and piezoelectric effect of ferroelectrets based on the polylactic acid (PLA) polymer. A distinctive feature of the manufactured films is that they are biodegradable. After a microstructure modification of carbon dioxide (CO2) foamed PLA sheets by hot-pressing treatment and corona polarization, these cellular films reveal large piezoelectric d₃₃ and d₃₁ responses in both quasi-static and dynamic modes. For freshly charged films, the maximum quasi-static piezoelectric coefficients are about 600 pC/N (d₃₃⁠⁠) and 44 pC/N (d₃₁⁠⁠) for a relatively thick film of 360 μm and a nominal porosity of about 60%. During the first 20 days after polarization, the piezoelectric activity decreases by half compared to the primary value, but then remains almost unchanged for a long time. Due to an already established inherent biocompatibility of PLA polymers, these eco-friendly ferroelectrets can be potentially used in various biological applications such as biosensors and microenergy harvesters embedded in tissue and artificial muscles.

description: We have discovered a new high proper motion cataclysmic variable (CV) in the SUPERBLINK proper motion survey, which is sensitive to stars with proper motions greater than 40 mas/yr. This CV was selected for follow-up observations as part of a larger search for CVs selected based on proper motions and their NUV-V and V-K$_{s}$ colors. We present spectroscopic observations from the 2.4m Hiltner Telescope at MDM Observatory. The new CV's orbital period is near 96 minutes, its spectrum shows the double-peaked Balmer emission lines characteristic of quiescent dwarf novae, and its V magnitude is near 18.2. Additionally, we present a full list of known CVs in the SUPERBLINK catalog.

description: A Feshbach resonance occurs when the energy of two interacting free particles comes to resonance with a molecular bound state. When approaching this resonance, dramatic changes in the interaction strength between the particles occur. Feshbach resonances have been an essential tool to control the atom interactions, which can even be switched from repulsive to attractive [1-4]. Thanks to Feshbach resonances many effects in ultracold atomic gases could be explored [5, 6]. Here we demonstrate a Feshbach resonance based on polariton spinor interactions that characterize the fundamental interaction process in polariton quantum systems. We show the clear enhancement of attractive interactions and the prompt change to repulsive interaction by tuning the energy of two polaritons with anti-parallel spins across the biexciton bound state energy. A mean field two-channel model quantitatively reproduces the experimental results. This observation paves the way for a new tool to tune the polariton interactions and to move forward into quantum correlated polariton physics.

description: La ricostruzione dell’Organistrum ha presentato una lunga serie di difficoltà, dovute all’esigua quantità di dati documentari e alle incertezze nell’interpretazione del repertorio iconografico. Letture multidisciplinari incrociate su questi materiali e molteplici tentativi di costruzione di un modello funzionante, confrontati puntualmente con le esigenze effettive della musica del secolo XII, hanno portato l’autore a una sintesi di decenni di ricerche su uno strumento rimasto finora poco considerato dai musicisti.

description: L’impiego di sistemi ibridi in muratura e legno strutturalmente efficaci rientra in una sperimentazione tecnologica molto antica che ha dato esiti differenti e della quale si può ritrovare traccia nella trattatistica storica. La diffusione di queste tecniche spesso riconosciuta in modo sistematico in area sismica, ma l’incremento della qualità costruttiva, data dall’unione dei due materiali, permette di migliorare il comportamento delle architetture non solo nel caso di azioni orizzontali ma anche per i carichi verticali. Per tali ragioni, la diffusione di questi saperi tecnici si riscontra anche in regioni a basso rischio sismico come il Trentino-Alto Adige. Nel presente contributo saranno discussi alcuni casi riscontrati in fortificazioni medievali della Provincia Autonoma di Trento.

description: CONTEXT: Self-efficacy is a concept researched in various areas of knowledge that impacts various factors such as performance, satisfaction, and motivation. In Software Engineering, it has mainly been studied in the academic context, presenting results similar to other areas of knowledge. However, it is also important to understand its impact in the industrial context. OBJECTIVE: Therefore, this study aims to understand the impact on the software development context with a focus on understanding the behavioral signs of self-efficacy in software engineers and how self-efficacy can impact the work-day of software engineers. METHOD: A qualitative research was conducted using semi-structured questionnaires with 31 interviewees from a software development company located in Brazil. The interviewees participated in a Bootcamp and were later assigned to software development teams. Thematic analysis was used to analyze the data. RESULTS: In the perception of the interviewees, 21 signs were found that are related to people with high and low self-efficacy. These signs were divided into two dimensions: social and cognitive. Also, 18 situations were found that can lead to an increase or decrease of self-efficacy of software engineers. Finally, 12 factors were mentioned that can impact software development teams. CONCLUSION: This work evidences a set of behavioral signs that can help team leaders to better perceive the self-efficacy of their members. It also presents a set of situations that both leaders and individuals can use to improve their self-efficacy in the development context, and finally, factors that can be impacted by self-efficacy in the software development context are also presented. Finally, this work emphasizes the importance of understanding self-efficacy in the industrial context.

description: The capacity of the channel defined by the stochastic nonlinear Schrödinger equation, which includes the effects of the Kerr nonlinearity and amplified spontaneous emission noise, is considered in the case of zero dispersion. In the absence of dispersion, this channel behaves as a collection of parallel per-sample channels. The conditional probability density function of the nonlinear per-sample channels is derived using both a sum-product and a Fokker-Planck differential equation approach. It is shown that, for a fixed noise power, the per-sample capacity grows unboundedly with input signal. The channel can be partitioned into amplitude and phase subchannels, and it is shown that the contribution to the total capacity of the phase channel declines for large input powers. It is found that a two-dimensional distribution with a half-Gaussian profile on the amplitude and uniform phase provides a lower bound for the zero-dispersion optical fiber channel, which is simple and asymptotically capacity-achieving at high signal-to-noise ratios (SNRs). A lower bound on the capacity is also derived in the medium-SNR region. The exact capacity subject to peak and average power constraints is numerically quantified using dense multiple ring modulation formats. The differential model underlying the zero-dispersion channel is reduced to an algebraic model, which is more tractable for digital communication studies, and in particular it provides a relation between the zero-dispersion optical channel and a $2 \times 2$ multiple-input multiple-output Rician fading channel. It appears that the structure of the capacity-achieving input distribution resembles that of the Rician fading channel, i.e., it is discrete in amplitude with a finite number of mass points, while continuous and uniform in phase.

description: A rapid and green procedure has been introduced for the preparation of pyrano[2,3-c]pyrazole and xanthene-1,8-dione derivatives in the presence of a natural catalyst in aqueous medium. Sodium tetraborate pentahydrate was found as a nontoxic or minimally toxic, readily available, cheap, and ecologically favorable agent catalyst for the synthesis of these important heterocyclic compounds. The introduced method offers some advantages such as high efficiency, an inexpensive and easy-to-handle catalyst, avoidance of organic solvents, and simple work-up that they are consistent with green chemistry.

description: La cintura per la sospensione della spatha costituisce uno degli elementi più significativi dei corredi funerari maschili di età longobarda; costituita da un insieme di guarnizioni che sembrano ripetersi secondo schemi definiti, essa consentiva al guerriero di portare l’arma al fianco. Malgrado le numerose proposte che hanno caratterizzato il dibattito italiano ed europeo, non si è ancora giunti all’elaborazione di un modello accettato e condiviso e rimangono aperti numerosi interrogativi in merito al ruolo delle singole guarnizioni metalliche e, nel complesso, al funzionamento dell’intero sistema. Il contributo presentato in questa sede ha l’obiettivo di analizzare i singoli elementi che componevano il set di guarnizioni delle cd. ‘cinture a cinque pezzi’ in ferro e di identificarne ruoli e funzioni, proponendo un modello di sospensione della spatha adattabile ai materiali longobardi.

So dient die Publikationsdatenbank PUBDB gleichzeitig als institutionelles Repositorium, Quelle für die Darstellung im Web und Basis für verschiedene Berichtsformate. Wie jedes Repositorium hält sie qualitativ hochwertige bibliographische, rechtliche und technische Daten sowie Volltexte.Als zentraler Ansprechpartner für die Abwicklung von Publikationsgebühren wurde PUBDB zusammen mit JuSER (Forschungszentrum Jülich) daher bereits 2016 um einen weiteren Datenblock ergänzt: Kosten (sowohl für Open als auch Closed Access). Die direkte Verknüpfung mit den bereits vorhandenen Datenbestandteilen erlaubt hier einerseits effiziente Prozesse und andererseits ein detaillierteres Monitoring als über das Buchführungssystem allein. So konnte z.B. der Monitoringbericht für das DFG Programm Open Access Publikationskosten weitestgehend automatisiert werden.Allerdings standen die Daten bisher nur lokal und in proprietären Formaten zur Verfügung. Eine Lieferung z.B. an OpenAPC war nicht möglich, da die so wichtigen automatisierten Wege noch nicht geebnet waren: Manuelle Aufarbeitungen von Daten in verschiedenen Formaten, Lieferformen und Definitionen bindet schlicht unnötig Personal.openCost hat dies grundlegend geändert. Da DESY jenes Konzept für die JOIN²-Kollaboration implementiert hat, stehen Kostendaten nun offen zur Ernte bereit und entsprechende Funktionen unmittelbar allen Partnern zur Verfügung. So können nun weitere Einrichtungen ohne zusätzlichen Aufwand z.B. an OpenAPC teilnehmen. Es besteht die Hoffnung, diesen Weg künftig auch für den Gesamtprozess des DFG Monitorings nutzen zu können.Wir werfen einen Blick darauf, warum sich ein zunächst aufwändig anmutender Weg wie die Schaffung einer XML-Ausgabe und das Konfigurieren einer OAI-Schnittstelle langfristig auch und ausdrücklich für kleine Einrichtungen auszahlt und wie wir unsere Prozesse so gestalten, dass diese mit den vorhandenen Ressourcen realisierbar sind.

description: We study two-cluster solutions of an ensemble of generic limit-cycle oscillators in the vicinity of a Hopf bifurcation, i.e. Stuart-Landau oscillators, with a nonlinear global coupling. This coupling leads to conserved mean-field oscillations acting back on the individual oscillators as a forcing. A reduction to two effective equations makes a linear stability analysis of the cluster solutions possible. These equations exhibit a $π$-rotational symmetry, leading to a complex bifurcation structure and a wide variety of solutions. In fact, the principal bifurcation structure resembles that of a 2:1 resonance tongue, while inside the tongue we observe an 1:1 entrainment.

description: As one of the drivers of feedback in active galactic nuclei (AGNs), the jets launched from supermassive black holes (SMBHs) are important for understanding the co-evolution of SMBHs and their host galaxies. However, the formation of AGN jets is far from clear. The discovery of gamma-ray narrow-line Seyfert 1 (NLS1) galaxies during the past two decades has provided us with a new means of studying the link between jets and accretion processes and the formation of jets. Here, we explore the coupling of jet and accretion discs in seven bright gamma-ray NLS1 galaxies by studying simultaneous optical/ultraviolet and X-ray observations of these systems taken by Swift. The results show that, except for 1H 0323+342 in which the X-rays are significantly contributed from the accretion disc, the observed X-ray emission of the other sources is dominated by the jet, and accretion process makes little contribution if not absent. Although the origin of the X-ray emission is different, the broad-band spectral shape characterized by alpha_ox and the X-ray flux is found to follow the same evolutionary trend in 1H 0323+342, PMN J0948+0022, and PKS 1502+036. For the remaining sources, the trend is not observed or the sampling is not dense enough.

description: Lo studio delle cesoie di età romana si inserisce nell’ambito dei progetti di ricerca sulla produzione tessile condotti dal Dipartimento dei Beni Culturali dell’Università di Padova. Nonostante tale strumento fosse adatto a molteplici utilizzi, è solitamente associato in letteratura alla tosatura ed è stato per questo considerato un indicatore delle attività tessili. Dopo aver condotto un censimento sistematico dei reperti rinvenuti in Italia settentrionale e datati tra la fine del II sec. a.C. e il V sec. d.C., si è deciso di intraprendere uno studio di dettaglio di otto specifici esemplari, dotati di caratteristiche differenti. Questi sono stati indagati tramite studio autoptico, raccogliendone un’adeguata documentazione per la loro riproduzione. Grazie all’utilizzo dell’archeologia sperimentale è stato possibile definire le diverse fasi di lavoro necessarie alla realizzazione di una singola cesoia a partire da una barra di ferro, determinare gli strumenti necessari alla lavorazione, comprendere i tempi e le risorse necessarie e identificare eventuali scarti o scorie di produzione.

description: The absolute light yield of a scintillator, defined as the number of scintillation photons produced per unit energy deposited, is a useful quantity for scintillator development, research, and applications. Yet, literature data on the absolute light yield of organic scintillators are limited. The goal of this work is to assess the suitability of the EJ-204 plastic scintillator from Eljen Technology to serve as a reference standard for measurements of the absolute light yield of organic scintillators. Four EJ-204 samples were examined: two manufactured approximately four months prior and stored in high-purity nitrogen, and two aged approximately eleven years and stored in ambient air. The scintillator response was measured using a large-area avalanche photodiode calibrated using low energy $γ$-ray and X-ray sources. The product of the quantum efficiency of the photodetector and light collection efficiency of the housing was characterized using an experimentally-benchmarked optical photon simulation. The average absolute light yield of the fresh samples, 9100 $\pm$ 400 photons per MeV, is lower than the manufacturer-reported value of 10400 photons per MeV. Moreover, the aged samples demonstrated significantly lower light yields, deviating from the manufacturer specification by as much as 26\%. These results are consistent with recent work showcasing environmental aging in plastic scintillators and suggest that experimenters should use caution when deploying plastic scintillators in photon counting applications.

description: The newly designed 4-(3,4,5-trimethoxybenzyloxy)phenoxy)phthalonitrile and zinc phthalocyanine compounds were synthesized. Fluorescence, degradation, aggregation, antioxidant, DNA cleavage, and antimicrobial properties of these compounds were investigated. Fluorescence, degradation, and aggregation properties were examined in different solvents. Suitable solvents were determined for the photophysical applications. Their dissolution in different solvents provides an advantage for applications. The ability to show emission spectra in different solvents provides the potential for use in applications. The antioxidant qualities of newly synthesized compounds were researched two methods by using free radical scavenging ability of DPPH and ferrous ion chelating ability. The maximum DPPH activity was observed by compound 5 causing 66.9% DPPH radical formation inhibition at 100 mg/L.

description: Large statistical samples of quasar spectra have previously indicated possible cosmological variations in the fine-structure constant, $α$. A smaller sample of higher signal-to-noise ratio spectra, with dedicated calibration, would allow a detailed test of this evidence. Towards that end, we observed equatorial quasar HS 1549$+$1919 with three telescopes: the Very Large Telescope, Keck and, for the first time in such analyses, Subaru. By directly comparing these spectra to each other, and by `supercalibrating' them using asteroid and iodine-cell tests, we detected and removed long-range distortions of the quasar spectra's wavelength scales which would have caused significant systematic errors in our $α$ measurements. For each telescope we measure the relative deviation in $α$ from the current laboratory value, $Δα/α$, in 3 absorption systems at redshifts $z_{\mathrm{abs}}=1.143$, 1.342, and 1.802. The nine measurements of $Δα/α$ are all consistent with zero at the 2-$σ$ level, with 1-$σ$ statistical (systematic) uncertainties 5.6--24 (1.8--7.0) parts per million (ppm). They are also consistent with each other at the 1-$σ$ level, allowing us to form a combined value for each telescope and, finally, a single value for this line of sight: $Δα/α=-5.4 \pm 3.3_{\mathrm{stat}} \pm 1.5_{\mathrm{sys}}$ ppm, consistent with both zero and previous, large samples. We also average all Large Programme results measuring $Δα/α=-0.6 \pm 1.9_{\mathrm{stat}} \pm 0.9_{\mathrm{sys}}$ ppm. Our results demonstrate the robustness and reliability at the 3 ppm level afforded by supercalibration techniques and direct comparison of spectra from different telescopes.

description: Il sito di Gu delon costituisce uno straordinario esempio di come l’Archeologia Sperimentale possa essere al tempo stesso un efficace strumento di ricerca e una forma immediata di divulgazione scientifica. L’edificazione di un castello del XIII secolo costituisce il movente attorno al quale si articolano idee e progetti che comprendono ricerca, formazione, educazione, turismo e occupazione: nel cantiere si sono potute affrontare le tematiche pi disparate, sperimentare approcci tanto diversi quanto innovativi, analizzare fenomeni mai osservati dal vivo e verificare la validit delle interpretazioni proposte dagli studiosi. L’attenzione si focalizzata non soltanto sugli aspetti materiali e sulle tecniche utilizzate, ma anche su questioni di natura antropologica e sociale: la cultura artigianale dell’uomo medievale, la trasmissione del sapere, l’organizzazione della catena operativa, la capacit di recuperare un sapere quasi del tutto perduto e comunicarlo al pubblico.

description: Deep learning (DL) applications are prevalent nowadays as they can help with multiple tasks. DL libraries are essential for building DL applications. Furthermore, DL operators are the important building blocks of the DL libraries, that compute the multi-dimensional data (tensors). Therefore, bugs in DL operators can have great impacts. Testing is a practical approach for detecting bugs in DL operators. In order to test DL operators effectively, it is essential that the test cases pass the input validity check and are able to reach the core function logic of the operators. Hence, extracting the input validation constraints is required for generating high-quality test cases. Existing techniques rely on either human effort or documentation of DL library APIs to extract the constraints. They cannot extract complex constraints and the extracted constraints may differ from the actual code implementation. To address the challenge, we propose ACETest, a technique to automatically extract input validation constraints from the code to build valid yet diverse test cases which can effectively unveil bugs in the core function logic of DL operators. For this purpose, ACETest can automatically identify the input validation code in DL operators, extract the related constraints and generate test cases according to the constraints. The experimental results on popular DL libraries, TensorFlow and PyTorch, demonstrate that ACETest can extract constraints with higher quality than state-of-the-art (SOTA) techniques. Moreover, ACETest is capable of extracting 96.4% more constraints and detecting 1.95 to 55 times more bugs than SOTA techniques. In total, we have used ACETest to detect 108 previously unknown bugs on TensorFlow and PyTorch, with 87 of them confirmed by the developers. Lastly, five of the bugs were assigned with CVE IDs due to their security impacts.

description: While the near-infrared wavelength regime is becoming more and more important for astrophysics there is a marked lack of spectrophotometric standard star data that would allow the flux calibration of such data. Furthermore, flux calibrating medium- to high-resolution échelle spectroscopy data is challenging even in the optical wavelength range, because the available flux standard data are often too coarsely sampled. We will provide standard star reference data that allow users to derive response curves from 300nm to 2500nm for spectroscopic data of medium to high resolution, including those taken with échelle spectrographs. In addition we describe a method to correct for moderate telluric absorption without the need of observing telluric standard stars. As reference data for the flux standard stars we use theoretical spectra derived from stellar model atmospheres. We verify that they provide an appropriate description of the observed standard star spectra by checking for residuals in line cores and line overlap regions in the ratios of observed (X-shooter) spectra to model spectra. The finally selected model spectra are then corrected for remaining mismatches and photometrically calibrated using independent observations. The correction of telluric absorption is performed with the help of telluric model spectra.We provide new, finely sampled reference spectra without telluric absorption for six southern flux standard stars that allow the users to flux calibrate their data from 300 nm to 2500 nm, and a method to correct for telluric absorption using atmospheric models.

description: Slides for a presentation held at the Open Access Week, University of Oslo: Abstract: In July 2022, the European Commission launched an Agreement On Reforming Research Assessment. After years of talking, there is significant momentum for changing how researchers are assessed. In this talk, I will present some work leading up to the new agreement and how Universities Norway took a lead when developing the Norwegian Career Assessment Matrix (NOR-CAM). The core idea is that academics need to get recognition for a broader range of activities. This is important for transitioning to more open research practices and diverse career paths within and outside academia.

description: Enterococcus faecalis is the third cause of nosocomial infections. To obtain the first comprehensive view of transcriptional organizations in this bacterium, we used a modified RNA-seq approach enabling to discriminate primary from processed 5'RNA ends. We also validated our approach by confirming known features in Escherichia coli. We mapped 559 transcription start sites and 352 processing sites in E. faecalis. A blind motif search retrieved canonical features of SigA- and SigN-dependent promoters preceding TSSs mapped. We discovered 95 novel putative regulatory RNAs, small- and antisense RNAs, and 72 transcriptional antisense organisations. Presented data constitute a significant insight into bacterial RNA landscapes and a step towards the inference of regulatory processes at transcriptional and post-transcriptional levels in a comprehensive manner.
