description: Supergiant Fast X-ray Transients (SFXT) are High Mass X-ray Binaries displaying X-ray outbursts reaching peak luminosities of 10$^{38}$ erg/s and spend most of their life in more quiescent states with luminosities as low as 10$^{32}$-10$^{33}$ erg/s. The main goal of our comprehensive and uniform analysis of the SFXT Swift triggers is to provide tools to predict whether a transient which has no known X-ray counterpart may be an SFXT candidate. These tools can be exploited for the development of future missions exploring the variable X-ray sky through large FoV instruments. We examined all available data on outbursts of SFXTs that triggered the Swift/BAT collected between 2005-08-30 and 2014-12-31, in particular those for which broad-band data, including the Swift/XRT ones, are also available. We processed all BAT and XRT data uniformly with the Swift Burst Analyser to produce spectral evolution dependent flux light curves for each outburst. The BAT data allowed us to infer useful diagnostics to set SFXT triggers apart from the general GRB population, showing that SFXTs give rise uniquely to image triggers and are simultaneously very long, faint, and `soft' hard-X-ray transients. The BAT data alone can discriminate very well the SFXTs from other fast transients such as anomalous X-ray pulsars and soft gamma repeaters. However, to distinguish SFXTs from, for instance, accreting millisecond X-ray pulsars and jetted tidal disruption events, the XRT data collected around the time of the BAT triggers are decisive. The XRT observations of 35/52 SFXT BAT triggers show that in the soft X-ray energy band, SFXTs display a decay in flux from the peak of the outburst of at least 3 orders of magnitude within a day and rarely undergo large re-brightening episodes, favouring in most cases a rapid decay down to the quiescent level within 3-5 days (at most).

description: Gamma-ray bursts (GRBs) are the most luminous transients in the universe and are utilized as probes of early stars, gravitational wave counterparts, and collisionless shock physics. In spite of studies on polarimetry of GRBs in individual wavelengths that characterized intriguing properties of prompt emission and afterglow, no coordinated multi-wavelength measurements have yet been performed. Here, we report the first coordinated simultaneous polarimetry in the optical and radio bands for the afterglow associated with the typical long GRB 191221B. Our observations successfully caught the radio emission, which is not affected by synchrotron self-absorption, and show that the emission is depolarized in the radio band compared to the optical one. Our simultaneous polarization angle measurement and temporal polarization monitoring indicate the existence of cool electrons that increase the estimate of jet kinetic energy by a factor of $>$ 4 for this GRB afterglow. Further coordinated multi-wavelength polarimetric campaigns would improve our understanding of the total jet energies and magnetic field configurations in the emission regions of various types of GRBs, which are required to comprehend the mass scales of their progenitor systems and the physics of collisionless shocks.

description: We discuss the nonconvex optimal shape design problem of minimizing the weight of a loaded beam subject to deflection constraints. We associate to it a convex minimization problem which will play the role of a dual. The algorithm we propose has a global character and iterates between the two optimization problems via a so called "resizing rule".

description: Scholarly knowledge about biodiversity is published in a rapidly increasing corpus of scientific publications. A substantial portion of taxonomic literature is available as unstructured portable document format (PDF) electronic documents. But the data contained, including occurrence records and characteristics, are locked up within these PDFs.

 Semantic enhancement, applied either retrospectively to legacy literature or prospectively through innovative cybertaxonomic publishing models, allows for the electronic mobilization of these data. Of course, a large portion of legacy taxonomic literature is not even digitized in the sense of having the pages scanned and converted into a PDF electronic document, much less having the underlying data mobilized. Even when we publish open access, the data remain closed. The Plazi semantic enhancement workflow facilitates the conversion of publications into findable, open accessible, interoperable, reusable (FAIR) data.

 So far, over 32K publications have been converted, resulting in 350K figures, 375K taxonomic treatments, 406K materials cited accessible through the Biodiversity Literature Repository. The data is directly reused by the Global Biodiversity Information Facility (GBIF) where it is the sole contributor of over 45,000 species, mainly insects, for which no other digital data is available. The system permits the building of applications focused on images (e.g. Ocellus) or taxonomic names (e.g. Synospecies). This workflow described in this presentation can be applied manually to selected legacy publications, or employ automation to process related articles in batches. Further changes in taxonomic publishing practices could lead to having electronic data elements routinely linked and mobilized.

description: Bu çalışma, çeşitli branşlardan öğretmenlere yönelik düzenlenen 'Öğretmen Yardımcısı Yapay Zeka' seminerlerinin, öğretmenlerin yapay zeka teknolojilerine yönelik farkındalık ve bilgi düzeylerini nasıl artırdığını incelemektedir. Dört grup halinde ve üçer saat süren seminerler, öğretmenlere yapay zeka araçlarını ders planlama, materyal oluşturma, öğrenci değerlendirme ve motivasyon artırma süreçlerinde nasıl kullanabileceklerini öğretmeyi amaçlamıştır. Araştırma, nitel ve nicel veri toplama yöntemleri kullanılarak 66 öğretmen ile yürütülmüştür.

Seminer öncesi ve sonrası anketler veri toplama aracı olarak kullanılmıştır. Seminer öncesi anket sonuçları, öğretmenlerin büyük çoğunluğunun yapay zeka teknolojileri hakkında sınırlı bilgiye sahip olduğunu göstermiştir. Seminer sonrası anketler ise bu teknolojilere yönelik farkındalık ve bilgi düzeylerinde önemli bir artış olduğunu ortaya koymuştur. Öğretmenler, yapay zekanın ders planlama, materyal oluşturma ve öğrenci değerlendirme süreçlerinde kullanılabilirliğine dair olumlu görüşler bildirmişlerdir. Ayrıca, seminerin içeriği ve sunumların anlaşılabilirliği hakkında genel olarak olumlu geri bildirimler alınmıştır.

Araştırma, yapay zeka eğitimlerinin öğretmenlerin teknoloji entegrasyonu konusunda daha bilinçli ve yetkin hale gelmelerine katkı sağladığını göstermektedir. Sonuç olarak, yapay zeka teknolojilerinin eğitimde kullanımının öğretmenler ve öğrenciler için önemli faydalar sağlayabileceği görülmüştür. Eğitim politikalarının, bu teknolojilerin entegrasyonunu teşvik etmesi ve öğretmenlerin bu teknolojileri etkili bir şekilde kullanmaları için gerekli eğitim ve kaynakları sağlaması gerektiği görülmüştür.

description: Understanding the nucleosynthetic origin of nitrogen and the evolution of the N/O ratio in the interstellar medium is crucial for a comprehensive picture of galaxy chemical evolution at high-redshift because most observational metallicity (O/H) estimates are implicitly dependent on the N/O ratio. The observed N/O at high-redshift shows an overall constancy with O/H, albeit with a large scatter. We show that these heretofore unexplained features can be explained by the pre-supernova wind yields from rotating massive stars (M$\gtrsim 10 \, \mathrm{M}_\odot$, $v/v_{\rm{crit}} \gtrsim 0.4$). Our models naturally produce the observed N/O plateau, as well as the scatter at low O/H. We find the scatter to arise from varying star formation efficiency. However, the models that have supernovae dominated yields produce a poor fit to the observed N/O at low O/H. This peculiar abundance pattern at low O/H suggests that dwarf galaxies are most likely to be devoid of SNe yields and are primarily enriched by pre-supernova wind abundances.

description: Recent breakthroughs in Large Language Models (LLMs), such as GPT-3 and Codex, now enable software developers to generate code based on a natural language prompt. Within computer science education, researchers are exploring the potential for LLMs to generate code explanations and programming assignments using carefully crafted prompts. These advances may enable students to interact with code in new ways while helping instructors scale their learning materials. However, LLMs also introduce new implications for academic integrity, curriculum design, and software engineering careers. This workshop will demonstrate the capabilities of LLMs to help attendees evaluate whether and how LLMs might be integrated into their pedagogy and research. We will also engage attendees in brainstorming to consider how LLMs will impact our field.

description: Approximately one-third of existing $γ$-ray sources identified by the $\textit{Fermi Gamma-Ray Space Telescope}$ are considered to be unassociated, with no known counterpart at other frequencies/wavelengths. These sources have been the subject of intense scrutiny and observational effort during the observatory's mission lifetime, and here we present a method of leveraging existing radio catalogs to examine these sources without the need for specific dedicated observations, which can be costly and complex. Via the inclusion of many sensitive low-frequency catalogs we specifically target steep spectrum sources such as pulsars. This work has found steep-spectrum radio sources contained inside 591 $\textit{Fermi}$ unassociated fields, with at least 21 of them being notable for having pulsar-like $γ$-ray properties as well. We also identify a number of other fields of interest based on various radio and $γ$-ray selections.

description: Türk müteahhitlik işletmeleri, 1970’li yıllardan itibaren yurt dışında faaliyet göstermeye başlamış ve birçok başarılı projeyi hayata geçirmişlerdir. Özellikle son yıllarda istikrarlı bir şekilde dünyanın en önde gelen işletmeleri arasında yer alan Türk müteahhitlik işletmeleri, 2022 yılında yurt dışında gerçekleştirilen faaliyetler baz alınarak yapılan değerlendirmede Çinli işletmelerin ardından dünyada ikinci sırada yer almıştır. Türk müteahhitlik işletmelerinin başarıları birçok araştırmaya konu olmuştur. Bu araştırmalar, elde edilen başarıların daha çok mühendislik faaliyetleri yönüne odaklanmış, işletmeleri yönetsel anlamda başarıya götüren etkenler ise yeterince ele alınmamıştır. Bu çalışmada yurt dışında çalışmaları bulunan Türk müteahhitlik işletmelerinin kazandıkları başarıların yönetsel açıdan kaynakları ve uygulamış oldukları yönetim tarzları ile uygulamaların tespit edilmesi amaçlanmıştır. Bu amaçla bu işletmelerin üçünden üst düzey yöneticileri ile kapsamlı görüşmelerde bulunulmuş ve veriler içerik analizine tabi tutulmuştur. Analizler neticesinde, Türk müteahhitlik işletmelerinin yurt dışı faaliyetlerinde elde ettikleri başarıların elde edilmesinde öne çıkan unsurlar liderlik, iş yapma biçimleri ve insan kaynakları uygulamalarında kültürel uyumlanma, güçlü yakın çevre ilişkileri, risk alma yetisi, bilgi ve tecrübe ile hızlı karar alma ve hızlı hareket edebilme yeteneği olarak tespit edilmiştir. Bu işletmelerin rakiplerine avantaj sağlayan ve dolayısı ile iyileştirilmesi gereken hususlar ise daha fazla devlet desteği ihtiyacı (garantörlük, finansman kolaylığı vb.) ve özellikle tasarım ile mimari açıdan kendilerini geliştirmeleri ihtiyacıdır.

description: Falls during walking are a major health issue in the elderly population. Older individuals are usually more cautious, work more slowly, take shorter steps, and exhibit increased step-to-step variability. They often have impaired dynamic balance, which explains their increased falling risk. Those locomotor characteristics might be the result of the neurological/musculoskeletal degenerative processes typical of advanced age or of a decline that began earlier in life. In order to help determine between the two possibilities, we analyzed the relationship between age and gait features among 100 individuals aged 20-69. Trunk acceleration was measured during 5-min treadmill session using a 3D accelerometer. The following dependent variables were assessed: preferred walking speed, walk ratio (step length normalized by step frequency), gait instability (local dynamic stability, Lyapunov exponent method), and acceleration variability (root mean square (RMS)). Using age as a predictor, linear regressions were performed for each dependent variable. The results indicated that walking speed, walk ratio and trunk acceleration variability were not dependent on age (R2<2%). However, there was a significant quadratic association between age and gait instability in the mediolateral direction (R2=15%). We concluded that most of the typical gait features of older age do not result from a slow evolution over the life course. On the other hand, gait instability likely begins to increase at an accelerated rate as early as age 40-50. This finding support the premise that local dynamic stability is likely a relevant early indicator of falling risk.

description: A growing avenue for determining the prevalence of life beyond Earth is to search for "technosignatures" from extraterrestrial intelligences/agents. Technosignatures require significant energy to be visible across interstellar space and thus intentional signals might be concentrated in frequency, in time, or in space, to be found in mutually obvious places. Therefore, it could be advantageous to search for technosignatures in parts of parameter space that are mutually-derivable to an observer on Earth and a distant transmitter. In this work, we used the L-band (1.1-1.9 GHz) receiver on the Robert C. Byrd Green Bank Telescope (GBT) to perform the first technosignature search pre-synchronized with exoplanet transits, covering 12 Kepler systems. We used the Breakthrough Listen turboSETI pipeline to flag narrowband hits ($\sim$3 Hz) using a maximum drift rate of $\pm$614.4 Hz/s and a signal-to-noise threshold of 5 - the pipeline returned $\sim 3.4 \times 10^5$ apparently-localized features. Visual inspection by a team of citizen scientists ruled out 99.6% of them. Further analysis found 2 signals-of-interest that warrant follow-up, but no technosignatures. If the signals-of-interest are not re-detected in future work, it will imply that the 12 targets in the search are not producing transit-aligned signals from 1.1-1.9 GHz with transmitter powers $>$60 times that of the former Arecibo radar. This search debuts a range of innovative technosignature techniques: citizen science vetting of potential signals-of-interest, a sensitivity-aware search out to extremely high drift rates, a more flexible method of analyzing on-off cadences, and an extremely low signal-to-noise threshold.

Searching for GRB Precursors with TESS

Subjects: Extragalactic Astrophysics

description: Gamma-ray bursts (GRBs) lie at cosmological distances and are among the brightest electromagnetic events known to occur in the universe. Favored models include collapsars for long GRBs and the merger of two compact objects for short GRBs, though details remain murky. Some models predict the presence of GRB progenitors with lifetimes of days to months, some of which are expected to be relatively bright (V < 18). These progenitors may be visible as point sources colocated with the GRB location weeks or months prior to the actual burst. However, while the detection of GRB optical afterglows has become almost routine, no burst precursor has yet been detected. One complication to the search for such precursors is that not knowing when and where GRBs will occur prior to their appearance makes searching for precursors difficult, due to the lack of high-precision photometry for periods of days to months prior to the burst itself. Full-frame images from TESS can address this lack, and I will report on results from using the TESS fields during the first 6 years of the mission to search for precursors to GRBs detected by the Swift Burst Alert Telescope (BAT).

description: The breakup of non-Newtonian droplets is ubiquitous in numerous applications. Although the non-Newtonian property can significantly change the droplet breakup process, most previous studies consider Newtonian droplets, and the effects of the non-Newtonian properties on the breakup process are still unclear. This study focuses on the secondary breakup of shear-thinning droplets by numerical simulation. The volume of fluid method is used to capture interface dynamics on adaptive grids. To compare shear-thinning droplets and Newtonian droplets, a new definition of the Ohnesorge number is proposed by considering the characteristic shear rate in the droplet induced by the airflow. The results show that compared with the Newtonian fluid, the shear-thinning properties can change the effective viscosity distribution inside the droplet, alter the local deformation, change the droplet morphology, and affect the transition in the droplet breakup regime.

description: Let K be a number field and let S be a finite set of places of K which contains all the Archimedean places. For any f(z) in K(z) of degree d at least 2 which is not a d-th power in \bar{K}(z), Siegel's theorem implies that the image set f(K) contains only finitely many S-units. We conjecture that the number of such S-units is bounded by a function of |S| and d (independently of K and f). We prove this conjecture for several classes of rational functions, and show that the full conjecture follows from the Bombieri--Lang conjecture.

description: We study a new kind of Courant algebroid on Poisson manifolds, which is a variant of the generalized tangent bundle in the sense that the roles of tangent and the cotangent bundle are exchanged. Its symmetry is a semidirect product of $β$-diffeomorphisms and $β$-transformations. It is a starting point of an alternative version of the generalized geometry based on the cotangent bundle, such as Dirac structures and generalized Riemannian structures. In particular, $R$-fluxes are formulated as a twisting of this Courant algebroid by a local $β$-transformations, in the same way as $H$-fluxes are the twist of the generalized tangent bundle. It is a $3$-vector classified by Poisson $3$-cohomology and it appears in a twisted bracket and in an exact sequence.

description: El presente artículo explora las representaciones de identidad social y repertorios lingüísticos en los textos identitarios publicados en las páginas oficiales de Facebook de Fridays For Future Spain (FFFS) y Fridays For Future Deutschland (FFFD) en contraste y comparación intercultural. Los criterios de análisis elaborados para tal propósito ponen de manifiesto que, si bien los ideales y objetivos de FFFS y FFFD son transversales a las consignas del movimiento transnacional, los textos identitarios socializados se re-enmarcan en discursos diferenciados, propios y contingentes a cada contexto sociocultural. Se concluye que el análisis contrastivo y comparativo de los textos identitarios auténticos de FFFS y FFFD ofrece provechosas aperturas para el fomento de las subcompetencias constitutivas de la mediación lingüística y cultural en el contexto de la enseñanza y aprendizaje del español como lengua extranjera. Tales sinergias se ilustran a través de una propuesta didáctica elaborada mediante el enfoque por tareas.
description: This article explores the representations of social identity and linguistic repertoires in the identity texts posted on the official Facebook pages of Fridays For Future Spain (FFFS) and Fridays For Future Deutschland (FFFD). The instrument of analysis developed for this purpose reveals that, although the ideals and objectives of FFFS and FFFD are transversal to the core principles of the transnational movement, the shared identity texts are reframed in distinct discourses that are specific and contingent to each sociocultural context. It is argued that the contrastive and comparative analysis of authentic identity texts of FFFS and FFFD offers valuable possibilities to foster the constitutive subcompetences of linguistic and cultural mediation in the context of the teaching and learning of Spanish as a foreign language. These synergies are illustrated by means of a didactic proposal elaborated using the task-based approach.
Instability-Enhanced Friction in the Presheath of Two-Ion-Species Plasmas

description: The speed at which ions enter a sheath is a fundamental property of a plasma that also provides a useful boundary condition in modeling. A recent theory proposed that this can be significantly influenced by an instability-enhanced friction force arising from two-stream instabilities in the presheath when multiple ion species are present. Although experiments appeared to confirm this theory, recent particle simulations have brought it into question. We reconcile this controversy using direct numerical solutions of the dispersion relation, which show that there is a dependence on the electron-ion temperature ratio that was not considered previously. In addition, particle-in-cell simulations are used to show that ion-ion two-stream instabilities can arise near the sheath edge and generate an enhanced ion-ion friction force. Only by accounting for the instability-enhanced friction force can theory predict the simulated ion speeds at the sheath edge.

description: In this study, we report on a detailed single pulse analysis of the radio emission from the pulsar J1401$-$6357 (B1358$-$63) based on data observed with the ultrawideband low-frequency receiver on the Parkes radio telescope. In addition to a weak leading component, the integrated pulse profile features a single-humped structure with a slight asymmetry. The frequency evolution of the pulse profile is studied. Well-defined nulls, with an estimated nulling fraction greater than 2\%, are present across the whole frequency band. No emission is detected with significance above 3$σ$ in the average pulse profile integrated over all null pulses. Using fluctuation spectral analysis, we reveal the existence of temporal-dependent subpulse drifting in this pulsar for the first time. A clear double-peaked feature is present at exactly the alias border across the whole frequency band, which suggests that the apparent drift sense changes during the observation. Our observations provide further confirmation that the phenomena of pulse nulling and subpulse drifting are independent of observing frequency, which suggest that they invoke changes on the global magnetospheric scale.

description: In this work, the Flux-Coordinate Independent (FCI) approach to plasma turbulence simulations is formulated for the case of generic, static magnetic fields, including those possessing stochastic field lines. It is then demonstrated that FCI is applicable to nonlinear turbulent problems with and without X-point geometry. In particular, by means of simulations with the FENICIA code, it is shown that the standard features of ITG modes are recovered with reduced toroidal resolution. Finally, ITG turbulence under the influence of a static island is studied on the transport timescale with ITER-like parameters, showing the wide range of applicability of the method.

description: As the deep learning rapidly promote, the artificial texts created by generative models are commonly used in news and social media. However, such models can be abused to generate product reviews, fake news, and even fake political content. The paper proposes a solution for the Russian Artificial Text Detection in the Dialogue shared task 2022 (RuATD 2022) to distinguish which model within the list is used to generate this text. We introduce the DeBERTa pre-trained language model with multiple training strategies for this shared task. Extensive experiments conducted on the RuATD dataset validate the effectiveness of our proposed method. Moreover, our submission ranked second place in the evaluation phase for RuATD 2022 (Multi-Class).

Quality and safety of eco-sustainable materials for food packaging applications

description: This “Innovative Ph.D. of industrial feature” project is focused on the study and development of innovative eco-sustainable technological solutions in the flexible food packaging sector aiming to improve two main aspects of current industrial interest: the eco-sustainability and the safety of food packaging materials. Currently, the environmental problem related to the disposal of plastics and the increasingly stringent directives that the various countries are adopting to fight against the environmental pollution deriving from plastic materials have directed research towards the development of eco-friendly materials that can substitute the conventional plastic ones. The packaging sector is the one that uses the highest amount of plastic, thus, the use of the so-called “biopolymers” in the food packaging field could be a strategy to reduce the environmental impact generated by the traditional plastics materials. However, their large-scale diffusion is still limited for strong technical limitations related to their poor processability with traditional equipment and lower mechanical, thermal and barrier performances than the conventional plastics. A food package must guarantee the toxicological safety of the packed food and an emerging issue in this field concerns the so called “Non-Intentionally Added Substances” (NIAS), which are compounds that, although not intentionally added, may be present in food contact materials and migrate into the food, being therefore a potential risk for human health. The presence of NIAS in food packaging materials has been recognized for the first time in EU Regulation 10/2011. However, their risk assessment is a very challenging task and there are no protocols made by the authorities on how it can be performed. Therefore, the comparison of different methods for their risk assessment and the analysis of the causes and conditions of formation of NIAS is of fundamental importance to improve the quality and toxicological safety standards of food packaging, considering also a possible more stringent evolution of the European legislation on this topic. The objectives of the present research project are the improvement of the sustainability of the food packaging, trough the development of flexible packaging solutions made by innovative and biodegradable materials, with a particular focus on packaging for frozen food applications and for oxygen-sensitive products, and the improvement of the safety of the food packaging, trough the study of the migration of Non Intentionally Added Substances (NIAS) in conventional packaging films. This project has been performed in partnership with L’Université de La Réunion (France), specialized in the biochemical and microbiological analysis of food and the BluPlast S.r.l. company, operating in the production of films for packaging applications...
