description: Spin-$1/2$ chains with alternating antiferromagnetic and ferromagnetic couplings have attracted considerable interest due to the topological character of their spin excitations. Here, using density functional theory and density matrix renormalization group methods, we have systematically studied the dimerized chain system Na$_2$Cu$_2$TeO$_6$. Near the Fermi level, the dominant states are mainly contributed by the Cu $3d_{x^2-y^2}$ orbitals highly hybridized with the O $2p$ orbitals in the nonmagnetic phase, leading to an "effective" single-orbital low-energy model. Furthermore, the bandwidth of the Cu $3d_{x^2-y^2}$ states is small ($\sim 0.8$ eV), suggesting that electronic correlations will strongly affect this system. By introducing such electronic correlations, we found this system is a Mott insulator. Moreover, by calculating the magnetic exchange interactions ($J_1$, $J_2$ and $J_3$), we explained the size and sign of the exchange interactions in Na$_2$Cu$_2$TeO$_6$, in agreement with neutron experiments. In addition, we constructed a single-orbital Hubbard model for this dimerized chain system, where the quantum fluctuations are taken into account. Both AFM and FM coupling ($\uparrow$-$\downarrow$-$\downarrow$-$\uparrow$) along the chain were found in our DMRG and Lanczos calculations, in agreement with DFT and neutron results. We also calculated the hole pairing binding energy $ΔE$ which becomes negative at Hubbard $U \sim 11$ eV, indicating incipient pairing tendencies. Finally, we also looked at various cases of hole doping that always exhibit tight pairs. Thus, we believe our results for Na$_2$Cu$_2$TeO$_6$ could provide guidance to experimentalists and theorists working on this dimerized chain system, such as short-range magnetic coupling, doping effects, and possible pairing tendencies.

description: The initial-boundary value problem (ibvp) for the $m$-th order dispersion Korteweg-de Vries (KdV) equation on the half-line with rough data and solution in restricted Bourgain spaces is studied using the Fokas Unified Transform Method (UTM). Thus, this work advances the implementation of the Fokas method, used earlier for the KdV on the half-line with smooth data and solution in the classical Hadamard space, consisting of function that are continuous in time and Sobolev in the spatial variable, to the more general Bourgain spaces framework of dispersive equations with rough data on the half-line. The spaces needed and the estimates required arise at the linear level and in particular in the estimation of the linear pure ibvp, which has forcing and initial data zero but non-zero boundary data. Using the iteration map defined by the Fokas solution formula of the forced linear ibvp in combination with the bilinear estimates in modified Bourgain spaces introduced by this map, well-posedness of the nonlinear ibvp is established for rough initial and boundary data belonging in Sobolev spaces of the same optimal regularity as in the case of the initial value problem for this equation on the whole line.

description: Heteroscedastic Gaussian process regression, based on the concept of chained Gaussian processes, is used to build surrogates to predict site-specific loads on an offshore wind turbine. Stochasticity in the inflow turbulence and irregular waves results in load responses that are best represented as random variables rather than deterministic values. Moreover, the effect of these stochastic sources on the loads depends strongly on the mean environmental conditions -- for instance, at low mean wind speeds, inflow turbulence produces much less variability in loads than at high wind speeds. Statistically, this is known as heteroscedasticity. Deterministic and most stochastic surrogates do not account for the heteroscedastic noise, giving an incomplete and potentially misleading picture of the structural response. In this paper, we draw on the recent advancements in statistical inference to train a heteroscedastic surrogate model on a noisy database to predict the conditional pdf of the response. The model is informed via 10-minute load statistics of the IEA-10MW-RWT subject to both aero- and hydrodynamic loads, simulated with OpenFAST. Its performance is assessed against the standard Gaussian process regression. The predicted mean is similar in both models, but the heteroscedastic surrogate approximates the large-scale variance of the responses significantly better.

description: In this manuscript, we study the behavior of charged isotropic compact stellar objects within the framework of the modified Gauss-Bonnety theory of gravity by considering the Tolman Kuchowicz spacetime. We use some matching conditions of spherically symmetric space-time with Bardeen model as an exterior geometry and examine the physical behavior of stellar structures. In the current analysis, we discuss the energy conditions to check the viability of our model. Many physical aspects have been examined, such as energy density, pressure evolution, equation of state parameter, and causality condition. Furthermore, an equilibrium condition can be visualized through the modified Tolman-Oppenheimer-Volkov equation. Further, we study mass-radius function, compactness and redshift function, which are some essential features of the charged compact star model. It is worthwhile to mention here for the current study that our stellar structure in the background of Bardeen's model is more viable and stable.

description: A quadratic approximation manifold is presented for performing nonlinear, projection-based, model order reduction (PMOR). It constitutes a departure from the traditional affine subspace approximation that is aimed at mitigating the Kolmogorov barrier for nonlinear PMOR, particularly for convection-dominated transport problems. It builds on the data-driven approach underlying the traditional construction of projection-based reduced-order models (PROMs); is application-independent; is linearization-free; and therefore is robust for highly nonlinear problems. Most importantly, this approximation leads to quadratic PROMs that deliver the same accuracy as their traditional counterparts using however a much smaller dimension -- typically, $n_2 \sim \sqrt n_1$, where $n_2$ and $n_1$ denote the dimensions of the quadratic and traditional PROMs, respectively. The computational advantages of the proposed high-order approach to nonlinear PMOR over the traditional approach are highlighted for the detached-eddy simulation-based prediction of the Ahmed body turbulent wake flow, which is a popular CFD benchmark problem in the automotive industry. For a fixed accuracy level, these advantages include: a reduction of the total offline computational cost by a factor greater than five; a reduction of its online wall clock time by a factor greater than 32; and a reduction of the wall clock time of the underlying high-dimensional model by a factor greater than two orders of magnitude.

description: Text-aware recommender systems incorporate rich textual features, such as titles and descriptions, to generate item recommendations for users. The use of textual features helps mitigate cold-start problems, and thus, such recommender systems have attracted increased attention. However, we argue that the dependency on item descriptions makes the recommender system vulnerable to manipulation by adversarial sellers on e-commerce platforms. In this paper, we explore the possibility of such manipulation by proposing a new text rewriting framework to attack text-aware recommender systems. We show that the rewriting attack can be exploited by sellers to unfairly uprank their products, even though the adversarially rewritten descriptions are perceived as realistic by human evaluators. Methodologically, we investigate two different variations to carry out text rewriting attacks: (1) two-phase fine-tuning for greater attack performance, and (2) in-context learning for higher text rewriting quality. Experiments spanning 3 different datasets and 4 existing approaches demonstrate that recommender systems exhibit vulnerability against the proposed text rewriting attack. Our work adds to the existing literature around the robustness of recommender systems, while highlighting a new dimension of vulnerability in the age of large-scale automated text generation.

description: We consider the flare prediction problem that distinguishes flare-imminent active regions that produce an M- or X-class flare in the future 24 hours, from quiet active regions that do not produce any flare within $\pm 24$ hours. Using line-of-sight magnetograms and parameters of active regions in two data products covering Solar Cycle 23 and 24, we train and evaluate two deep learning algorithms -- CNN and LSTM -- and their stacking ensembles. The decisions of CNN are explained using visual attribution methods. We have the following three main findings. (1) LSTM trained on data from two solar cycles achieves significantly higher True Skill Scores (TSS) than that trained on data from a single solar cycle with a confidence level of at least 0.95. (2) On data from Solar Cycle 23, a stacking ensemble that combines predictions from LSTM and CNN using the TSS criterion achieves significantly higher TSS than the "select-best" strategy with a confidence level of at least 0.95. (3) A visual attribution method called Integrated Gradients is able to attribute the CNN's predictions of flares to the emerging magnetic flux in the active region. It also reveals a limitation of CNN as a flare prediction method using line-of-sight magnetograms: it treats the polarity artifact of line-of-sight magnetograms as positive evidence of flares.

description: We investigate dimerized quantum spin systems using the spin functional renormalization group approach proposed by Krieg and Kopietz [Phys. Rev. B 99, 060403(R) (2019)] which directly focuses on the physical spin correlation functions and avoids the representation of the spins in terms of fermionic or bosonic auxiliary operators. Starting from decoupled dimers as initial condition for the renormalization group flow equations, we obtain the spectrum of the triplet excitations as well as the magnetization in the quantum paramagnetic, ferromagnetic, and thermally disordered phases at all temperatures. Moreover, we compute the full phase diagram of a weakly coupled dimerized spin system in three dimensions, including the correct mean field critical exponents at the two quantum critical points.

description: Technology has arisen as a powerful tool for enhancing student’s learning and engagement in science education, particularly in the context of elementary inquiry-based science education (IBSE). This systematic review examines the use of technology in elementary IBSE over the past decade, analyzing 22 empirical studies to identify research trends, explore relationships among inquiry phases and process skills, and identify examples of technology utilization and affordances. The study reveals that technology has mainly been used to support students’ observation and data interpretation skills during the investigation phase of inquiry. However, it also indicates that technology has the potential to support other science process skills in other phases of inquiry in a variety of ways. Supporting students to capture and collect data, providing learning materials, and linking the real-world context were the three predominant affordances. Furthermore, the analysis suggests research gaps in the use of emerging technology and insufficient attention paid to employing technology to support students’ modeling processes and the use of simulations. These findings point to the need for further investigation to fully explore the potential of technology in supporting students’ learning and engagement in elementary IBSE.

description: WASP-69 b is a hot, inflated, Saturn-mass planet 0.26 Mjup with a zero-albedo equilibrium temperature of 963 K. Here, we report the JWST 2 to 12 um emission spectrum of the planet consisting of two eclipses observed with NIRCam grism time series and one eclipse observed with MIRI LRS. The emission spectrum shows absorption features of water vapor, carbon dioxide and carbon monoxide, but no strong evidence for methane. WASP-69 b's emission spectrum is poorly fit by cloud-free homogeneous models. We find three possible model scenarios for the planet: 1) a Scattering Model that raises the brightness at short wavelengths with a free Geometric Albedo parameter 2) a Cloud Layer model that includes high altitude silicate aerosols to moderate long wavelength emission and 3) a Two-Region model that includes significant dayside inhomogeneity and cloud opacity with two different temperature-pressure profiles. In all cases, aerosols are needed to fit the spectrum of the planet. The Scattering model requires an unexpectedly high Geometric Albedo of 0.64. Our atmospheric retrievals indicate inefficient redistribution of heat and an inhomogeneous dayside distribution, which is tentatively supported by MIRI LRS broadband eclipse maps that show a central concentration of brightness. Our more plausible models (2 and 3) retrieve chemical abundances enriched in heavy elements relative to solar composition by 6x to 14x solar and a C/O ratio of 0.65 to 0.94, whereas the less plausible highly reflective scenario (1) retrieves a slightly lower metallicity and lower C/O ratio.

description: Tachytes galeatus Pulawski, species nova
Figures 18–20.
 NAME DERIVATION.— Galeatus is an adjective derived from galea, which is unusually long in this species.
 RECOGNITION.— Like T. argyropis and unlike all other Madagascan Tachytes, the galea of this species is longer than the scape, as in Figs. 1 and 2 (rather than shorter) and the first article of the labial palpus is about as long as the scape, as in Fig. 3 (rather than markedly shorter). Unlike T. argyropis, the palpal formula of T. galeatus is 6+4 (rather than 5+3); see the key for other differences.
 Tachytes galeatus resembles several continental African species in having an elongate galea and the first article of the labial palpus and in lacking the golden setae arranged in a checkered pattern on the gastral terga (these setae are present in T. basilicus Guérin-Méneville and its relatives). It differs from all these species in having the gaster dark reddish or at least with dark reddish zones rather than all black.
 DESCRIPTION.— Head round in frontal view. Gena in dorsal view slightly narrower than in T. panzeri (Dufour). Galea 1.5 × as long as scape. First article of labial palpus about as long as scape.
Appressed silvery pilosity concealing integument on pronotal collar, sparse and not concealing integument on remaining thorax and propodeum (scutum anterolaterally without conspicuous appressed pilosity). Setae of postocellar area as long as 0.5-0.6 × scape, those on scutum 0.4 × scape in female, 0.5 × in male; sternum II without erect setae in female, in male with erect setae posteromedially (setal length about 2.0 × midocellar diameter).
Head, thorax and propodeum black; male

description: The MUonE experiment, that aims to provide a precise measurement of the hadronic vacuum polarization contribution to the muon $g-2$ via elastic muon-electron scattering, has also the potential to explore the parameter space of light new physics. Exploiting the process $μ^- N \to μ^- N X$, where $N$ is the target nucleus and X is a new physics light mediator, we demonstrate that MUonE can be sensitive to new regions of parameter space for sub-GeV dark photons. In particular, thanks to its muon beam, MUonE will be able to explore uncharted parameter space regions for the $L_μ-L_τ$ model. Finally, we also find that MUonE can probe the parameter space of axion-like particles for different assumptions of the couplings to electrons, muons and photons.

description: ‘A lack of prior knowledge in the other discipline’ is often given by geoscience instructors to explain why students struggle to apply knowledge from other disciplines to the Earth. We examine this assumption by considering the disciplinary crossing of buoyancy (physics) to isostasy (geoscience). We investigate the teachers’ perspective through workshops, and use the theoretical framework of Interdisciplinary Reasoning and Communication to explore what geoscience textbooks ask of students. Most introductory textbooks rely on students applying pre-existing knowledge of hydrostatics in a geoscience context (forwards transfer), while intermediate and advanced textbooks develop the necessary physics explicitly in a geoscientific context (backwards transfer). Moreover, introductory textbooks frequently use analogies for concrete translation between physics and geoscience ideas, but the analogical relations and where they break down (relational translations), receive little attention. This places high demands on students’ prior understanding of hydrostatics to successfully integrate and transfer knowledge from physics to geoscience. If students lack the relevant physics background, introductory textbooks may force them to rely on intuitive ideas of physics, potentially reinforcing old, and giving rise to new misconceptions. Our results move the focus from perceived shortcomings of students to the demands made on them in interdisciplinary learning.

description: Learners are expected to discuss and debate, using scientific evidence, the Socio-Scientific Issues (SSI) that often overlap with personal experiences and ethical dilemmas. This study investigated the reasoning of 24 Grade 8 Lebanese students when arguing about a scientific scenario as opposed to an SSI. It also examined how students make decisions and reason about SSIs. Results showed that students’ reasoning is more emotional in socio-scientific contexts than in scientific ones. Also, scientific reasoning was based on macroscopic (observed) characteristics of the phenomenon in an SSI but was based on microscopic (cellular/molecular details of mechanisms) features of the phenomenon in scientific contexts. Cultural, social, and ethical considerations influenced students’ decisions and reasons when constructing arguments. We discuss the results in light of the literature on reasoning about SSIs and provide instructional implications on how to teach argumentation within SSIs to enhance student reasoning.

3.4 km long underground superconducting 110 kV cable as part of the Dutch electricity grid, in 
the city of Enschede. HTS cables have already been demonstrated on a relatively small scale in 
other countries, but they are usually not part of the meshed high-voltage grid and the length of 
the relevant cable section generally does not exceed 1 km. In 2009, a 600-meter section of HTS 
cable was installed in New York, and in 2014 a 1-km long section was taken in operation in Essen, 
Germany to replace a 10 kV AC medium-voltage line.
In the Supernet NL program, TenneT is working together with several leading knowledge institutes 
including University of Twente, Delft University of Technology, the Institute of Science and Sustain-
able Development (IWO), HAN University of Applied Sciences and RH Marine. These institutes have 
been investigating control engineering aspects and the requirements the cable must meet. 
In the meantime, the tender process has been started which consists of two phases. In the fi rst 
phase (summer 2017) appropriate candidates are selected directly followed by a call for tender in 
August. Receipt of the best and fi nal offer is scheduled for the end of November.
In the presentation, the project will be introduced and requirements will be discussed, specifi cally 
focusing on the cryogenic aspects.

description: Are WO-type Wolf Rayet (WR) stars in the final stage of massive star evolution before core-collapse? Although WC- and WO-type WRs have very similar spectra, WOs show a much stronger O VI $λλ$3811,34 emission-line feature. This has usually been interpreted to mean that WOs are more oxygen rich than WCs, and thus further evolved. However, previous studies have failed to model this line, leaving the relative abundances uncertain, and the relationship between the two types unresolved. To answer this fundamental question, we modeled six WCs and two WOs in the LMC using UV, optical, and NIR spectra with the radiative transfer code CMFGEN in order to determine their physical properties. We find that WOs are not richer in oxygen; rather, the O VI feature is insensitive to the abundance. However, the WOs have a significantly higher carbon and lower helium content than the WCs, and hence are further evolved. A comparison of our results with single-star Geneva and binary BPASS evolutionary models show that while many properties match, there is more carbon and less oxygen in the WOs than either set of evolutionary model predicts. This discrepancy may be due to the large uncertainty in the $^{12}$C+$^4$He$\rightarrow^{16}$O nuclear reaction rate; we show that if the Kunz et al. rate is decreased by a factor of 25-50%, then there would be a good match with the observations. It would also help explain the LIGO/VIRGO detection of black holes whose masses are in the theoretical upper mass gap.

description: While a trans-disciplinary approach has been suggested within school science learning to facilitate the role of science education for societal development, lacking is a conceptualisation with respect to what trans-disciplinarity is, why it is needed, and how it can potentially be implemented in the classroom. In seeking to address this limitation, this study undertakes a systematically literature review of research articles published between 2011 and 2022, within the scope of trans-disciplinarity at school level science education. The five key transdisciplinary attributes are identified as – complexity, liberation, inclusion, transcendence beyond education and reflection, leading to the identification of 12 key dimensions of trans-disciplinarity. Based on this finding, a model is put forward with respect to implementing trans-disciplinarity within school level science teaching-learning, incorporating all identified dimensions as an approach towards addressing wicked problems within the society. The significance of this study lies on the conceptualisation of trans-disciplinarity in a holistic sense, so as to address a wider societal development through school science education.
Tecniche di fotomodellazione 3d e impiego dei SAPR.  Il caso della media valle del Sinni (Basilicata meridionale)
Creators: name: Vitale, Valentino
Publisher: name: University of Cagliari

description: Le attività di ricerca e l’impiego di nuove e recenti tecnologie, in qualità di metodologia innovativa per la ricerca archeologica sul campo, sono tutte sperimentazioni effettuate nel triennio 2015-2017 nella media valle del Sinni in Basilicata (Italia Meridionale). Obiettivo di tali nuove indagini è stato lo studio del sistema insediativo e dell’organizzazione del paesaggio medievale della vallata in cui ancora si conservano significative tracce di insediamenti e strutture; i suoi limiti cronologici prendono in considerazione i secoli centrali del medioevo, dalla fine del IX al XV sec. d.C. Le procedure di documentazione sviluppate durante questa ricerca seguono alcune soluzioni per ottimizzare le tecniche di rilievo dei dati. A questi problemi hanno ovviato recentemente tutti i software di fotomodellazione tridimensionale, i quali, oltre a realizzare modelli 3d forniscono ortofotopiani dell’area da indagare. I modelli tridimensionali costituiscono un documento unico dello stato attuale dei singoli beni caratterizzato da informazioni metriche, geometriche e materiche, utili alla ricostruzione e alla documentazione stratigrafica archeologica e architettonica. Le procedure di modellazione 3d sono da annoverare tra i metodi recentemente applicabili allo studio conoscitivo di un sito. Le possibilità recenti di impiego di sistemi apr (droni), inoltre, permettono di ottenere aerofotogrammi di qualsiasi aerea in tempi ridotti ed economicamente vantaggiosi.

Remarks. This species was identified from Odessa and the side arm of the Dnieper River in Aleschki, Ukraine. It is distributed Eurasia into the Black, Caspian, and Aral Sea basins. Afghanistan is not included in the natural distribution range of the species. The presence of the species needs clarification.
The orders with the largest numbers of species in the ichthyofauna of Afghanistan are the Cypriniformes (88 species), followed by the Siluriformes (14 species), the Anabantiformes (4 species), the Acipenseriformes, the Salmoniformes, and the Cyprinodontiformes (3 species in each). At the family level, the Cyprinidae have the greatest number of species (36 species; 29.8% of the total species), followed by the Nemacheilidae (22 species), the Leuciscidae (12 species), the Danionidae (8 species), and the Sisoridae (6 species). Along the way, a total of 48 species previously reported from Afghanistan have been excluded from the checklist, either in the present study or in previous studies.
Out of 121 fish species distributed in Afghanistan, 44 species have economic importance, seven species have regional economic value, while 34 species have no economic importance. Although a total of 25 species are not of economic importance, they are caught and consumed as food by local people. Among the species that are generally found as exotic, eigth species are aquarium fish species while three species are potentially aquarium species.

description: We consider the implications of the CDF collaboration high-precision measurement of the W boson mass on models with a non-standard Higgs. We show that this requires an enhancement of 3-10% in the non-standard Higgs coupling to the gauge bosons. This is naturally accommodated in dynamical models such as the dilaton Higgs, the Technicolor and glueball Higgs. The needed composite scale between 2 and 3 TeV can also explain the muon g-2 anomaly, as well as possible violations of lepton flavour universality.

description: Exploiting the notion of measurement-induced nonlocality [Phys.Rev. Lett. 106, 120401 (2011)], we introduce a new measure to quantify the nonbilocal correlation. We establish a simple relation between the nonlocal and nonbilocal measures for the arbitrary pure input states. Considering the mixed states as inputs, we derive two upper bounds of affinity-based nonbilocal measure. Finally, we have studied the nonbilocality of a different combinations of input states.

 MEXICO. Nayarit: along route 28 between Tepic and Jalcacatlan [Nay rte. 66 or Mex. rte. 76 and Jalcocotán on recent maps], between KM 14 and KM 15, [ca. 21°31′47.25′′N, 105° 02′0.74′′W], ca. 1000 m, 7-I-1979 (flr, frt), T. Croat 45204 (MO); Tepic, 5-I–6-II 1892 (flr), E. Palmer 2007 (US).
 These two collections from west-central Nayarit are the first records of J. phlebodes from the state, extend the distribution of the species ca. 225 km south of its nearest known locale in southern Sinaloa, and closely resemble conspecifics from other regions of northwestern Mexico. Indeed, the 2-aperturate pollen with 2–2.5 rows of insulae (to peninsulae) of Croat 45204 matches pollen previously noted for the species (Daniel 2004). These collections from Nayarit differ from/augment information in Daniel’s (2004) description of plants occurring to the north only in the following minor (and mostly continuous) characteristics: bracteoles up to 7 mm long and down to 0.3 mm wide; corolla ± infundibuliform with the tube slightly expanding ca. 4 mm distal to the base and thence slightly expanded toward the mouth, the upper lip up to 11 mm long, and the lower lip up to 11.5 mm long with lobes up to 5 mm long; and the gap between the two anther thecae down to 0.2 mm long, and the lower theca with a basal appendage down to 0.1 mm long. The species has been reported previously from Chihuahua, Durango, Sonora, and Sinaloa (Daniel 2004).
