description: Efficient scalar multiplication in Abelian groups (which is an important operation in public key cryptography) can be performed using digital expansions. Apart from rational integer bases (double-and-add algorithm), imaginary quadratic integer bases are of interest for elliptic curve cryptography, because the Frobenius endomorphism fulfils a quadratic equation. One strategy for improving the efficiency is to increase the digit set (at the prize of additional precomputations). A common choice is the width\nbd-$w$ non-adjacent form (\wNAF): each block of $w$ consecutive digits contains at most one non-zero digit. Heuristically, this ensures a low weight, i.e.\ number of non-zero digits, which translates in few costly curve operations. This paper investigates the following question: Is the \wNAF{}-expansion optimal, where optimality means minimising the weight over all possible expansions with the same digit set? The main characterisation of optimality of \wNAF{}s can be formulated in the following more general setting: We consider an Abelian group together with an endomorphism (e.g., multiplication by a base element in a ring) and a finite digit set. We show that each group element has an optimal \wNAF{}-expansion if and only if this is the case for each sum of two expansions of weight 1. This leads both to an algorithmic criterion and to generic answers for various cases. Imaginary quadratic integers of trace at least 3 (in absolute value) have optimal \wNAF{}s for $w\ge 4$. The same holds for the special case of base $(\pm 3\pm\sqrt{-3})/2$ and $w\ge 2$, which corresponds to Koblitz curves in characteristic three. In the case of $τ=\pm1\pm i$, optimality depends on the parity of $w$. Computational results for small trace are given.

description: New York City space puts forward multifold arrays of reflection on the state of the contemporary human self, in particular, of human beings in their interaction with an avantgarde, pompous, profit-oriented, world-reaching, rapid, and ephemeral space. Two post 9/11 Don DeLillo novels: Cosmopolis (2003) and Falling Man (2007) meticulously exhibit the spatial and temporal impact on urban environment and its inhabitants. The present paper scans New York’s urban space in these two novels, categorizing it into exteriors that encompass Manhattan’s streets and squares, and interiors that encompass hair salons, a ruined private flat and the destroyed Twin Towers. These spaces are scrutinized through an interdisciplinary approach that combines fiction with urban and social theory using views of Marshal Berman, Kwame Appiah, Gaston Bachelard, Michel Foucault among others. Revealing cultural divides in public spaces and a dual reality in confined spaces, the close analysis outlines aspects of DeLillo’s early 21st-century New York in which space is not detached from time in shaping an estranged self. The analysis, further, suggests that the accepted break in the flow of creativity and everyday life in the world city before and after 9/11, is, on the contrary, a continuous stream of trauma and a repeated pattern of destruction and creation.

description: Symmetry is a fundamentally important concept in many branches of physics. In this work, we discuss two types of symmetries, external symmetry and internal symmetry, which appear frequently in controlled quantum spin chains and apply them to study various controllability problems. For spin chains under single local end control when external symmetries exists, we can rigorously prove that the system is controllable in each of the invariant subspaces for both XXZ and XYZ chains, but not for XX or Ising chains. Such results have direct applications in controlling antiferromagnetic Heisenberg chains when the dynamics is naturally confined in the largest excitation subspace. We also address the theoretically important question of minimal control resources to achieve full controllability over the entire spin chain space. In the process we establish a systematic way of evaluating the dynamical Lie algebras and using known symmetries to help identify the dynamical Lie algebra.

description: The Covid-19 pandemic and the transition to online teaching and learning have led language teachers to re-examine and adjust their approaches to teaching to reach and involve learners despite physical distance. Simultaneously, an ever-growing abundance ¬of audio and audio-visual resources for language learning have become available at a click. These may offer a solution to tackle the changing teaching scenario, for listening leads not only to the development of listening skills, but also to holistic language development. This study aims to investigate the effectiveness of cooperative group presentations of audio and audio-visual texts. Learners were given an indicative structure to follow to render their presentations interactive for the whole class. Essential components were language-focus activities, including dictation. The experience was measured quantitively with listening level tests (Cambridge format, B2) and qualitatively through a post-course questionnaire on learner satisfaction. Results reveal an overall improvement in listening skills and positive feedback from participants.

A Corpus-based Approach to Language Learning
Creators: name: Marcella, Vanessa
Publisher: name: Iperstoria
Year: 2023

description: The use of corpus linguistics (CL) tools and methods has been shown to be of great help in fostering language learning. As argued by Aston (2000), language pedagogy has started to plan and create corpora to fit its own principles and address its own needs. Most studies focus on classroom activities based on concordances and lexical/grammatical analyses carried out on corpora (McEnery et al. 2006). To date, CL has often been combined with teaching specific topics to carry out text and discourse analyses, and data-driven learning (Friginal 2018). Therefore, it is important to further investigate the use of corpora as a valuable resource for language education. This work is testimony to the usefulness of corpus linguistics and corpus-based analyses for pedagogical purposes, while encouraging students to explore language autonomously and draw their own conclusions and considerations. Indeed, this paper outlines how CL can help learners, with different levels of language proficiency, approach English for Specific Purposes using authentic and concrete examples, and simultaneously lead them to develop new skills which may be integrated within their field of study. The case study occurred in a distance learning context with first-year students majoring in Data Science and Business Analytics at the University of Calabria. The main objective was to enhance students’ motivation while improving their English competences using statistical analyses and corpus tools to investigate data retrieved from the social network Instagram and related to the topic of climate change. In particular, hands-on activities allowed students to create their own corpora, analyze language use through the corpus analysis toolkit AntConc (3.5.8), and carry out topic framing. Students’ final projects were then discussed at the oral exam.

description: The authors investigate the spontaneous emission dynamics of self-assembled InGaAs quantum dots embedded in GaAs photonic crystal waveguides. For an ensemble of dots coupled to guided modes in the waveguide we report spatially, spectrally, and time-resolved photoluminescence measurements, detecting normal to the plane of the photonic crystal. For quantum dots emitting in resonance with the waveguide mode, a ~21x enhancement of photoluminescence intensity is observed as compared to dots in the unprocessed region of the wafer. This enhancement can be traced back to the Purcell enhanced emission of quantum dots into leaky and guided modes of the waveguide with moderate Purcell factors up to ~4x. Emission into guided modes is shown to be efficiently scattered out of the waveguide within a few microns, contributing to the out-of-plane emission and allowing the use of photonic crystal waveguides as broadband, efficiency-enhancing structures for surface-emitting diodes or single photon sources.

Integrating the Formative and Summative Post Covid-19 in a Blended Learning Approach to Higher Educational Assessment
Creators: name: Hartle, Sharon
Publisher: name: Iperstoria
Year: 2023

description: The response to the Covid-19 pandemic in Europe, reflecting a general move towards remote working, has been overwhelmingly one of turning to Emergency Remote Teaching (ERT) described as a “temporary solution to an immediate problem” (Bozkurt and Sharma 2020, ii). ERT is often seen from a negative viewpoint, linked to a reactive approach to teaching (Golden 2020; Murphy 2020) with a lack of planning or expertise. This means of delivery, however, has also taught us many lessons, some of which may provide us with new opportunities and ways of working in the future (Hodges et al. 2020; Hartle 2020; Thomas et al. 2021). When considering the assessment of language competence one of these lessons is that formative assessment is more appropriate to asynchronous, online contexts and summative assessment is suited rather to the synchronous, face to face spaces. In Higher Education (HE) contexts in the past summative assessment has generally been conducted in person, in a physical context because of concerns related to exam security (Nusche 2008; Pachler et al. 2010). The challenge now, where online teaching is increasingly becoming part and parcel of the educational repertoire, however, is to integrate both the formative and the summative in a new form of blended learning (BL) for the future. This is a future where the approach to teaching in online digital contexts both synchronously and asynchronously will no longer be ERT but a principled, planned approach to combining the digital with the traditional.

description: Bridge clearances can vary from lane-to-lane beneath overpasses, and can often be difficult to measure due to high traffic volumes. Therefore, a mobile LiDAR unit was utilized in this project to obtain the bridge clearance heights on the Western Kentucky Parkway. The LiDAR information was collected at 400,000 points-per-second at a driving speed of 30 mph. Hand measurements were also taken on each bridge to assist in quantifying the potential error between field measurements and LiDAR measurements. The results of the collected LiDAR data appear to be less than 1.2 inches, which appears to be in line with both manufactures and industry standards.

description: When a binary fluid demixes under a slow temperature ramp, nucleation, coarsening and sedimentation of droplets lead to an oscillatory evolution of the phase separating system. The advection of the sedimenting droplets is found to be chaotic. The flow is driven by density differences between the two phases. Here, we show how image processing can be combined with particle tracking to resolve droplet size and velocity simultaneously. Droplets are used as tracer particles, and the sedimentation velocity is determined. Taking these effects into account, droplets with radii in the range of 4 -- 40 micrometers are detected and tracked. Based on this data we resolve the oscillations in the droplet size distribution which are coupled to the convective flow.

description: Fire‐gilding is a historic technique for the application of golden layers on a number of different base materials utilizing a gold amalgam. This technique leaves a significant amount of Hg in the golden layer, giving archeometrists a reliable indicator to identify fire‐gildings. Recent findings on presumably fire‐gilded objects have shown in several cases significantly lower Hg content than previously studied objects. This prompted a synchrotron‐based X‐ray fluorescence investigation into the Hg distribution along the material–gilding interface, as well as a series of measurements regarding the Hg content development in fire‐gilded samples during artificial aging. This work presents findings on laboratory‐prepared fire‐gildings, indicating an Hg enrichment at the interface of fire‐gilded silver samples. Notably, such an enrichment is missing in fire‐gilded copper samples. Further, it is confirmed that fire‐gilded layers typically do not undercut an Hg bulk content of 5%. In this light, it seems improbable that ancient samples that contain <5% Hg are fire‐gilded. The results presented in this study might lead to a non‐destructive method to identify the Hg enrichment at the interface. This might be obtained by a combination of different non‐destructive measurements and might also work unambiguously in samples in which the gold top layer is altered.

description: The population of compact extragalactic sources contribute to the non-Gaussianity at Cosmic Microwave Background frequencies. We study their non-Gaussianity using publicly available full-sky simulations. We introduce a parametrisation to visualise efficiently the bispectrum and we describe the scale and frequency dependences of the bispectrum of radio and IR point-sources. We show that the bispectrum is well fitted by an analytical prescription. We find that the clustering of IR sources enhances their non-Gaussianity by several orders of magnitude, and that their bispectrum peaks in the squeezed triangles. Examining the impact of these sources on primordial non-Gaussianity estimation, we find that radio sources yield an important positive bias to local fNL at low frequencies but this bias is efficiently reduced by masking detectable sources. IR sources produce a negative bias at high frequencies, which is not dimmed by the masking, as their clustering is dominated by faint sources.

description: A 1500 Mhz. ground coupled, ground penetrating radar antenna was used to identify both the horizontal alignment and the vertical displacement of the concrete tie-bars and the transverse joint dowel bar assembles on a Portland-Cement-Concrete-Pavement (PCCP) on US 60 in McCracken County, KY. Approximately 5 lanes miles of PCCP were evaluated using the 1500 Mhz. ground coupled antenna. Results indicate that only one transverse dowel basket out of an approximate total of 1,760 were within 4.17 inches of the pavement surface. Seven transverse dowel baskets were misaligned four inches or greater from the location of the sawed joint. These areas represent 0.45 percent of the total transverse joints on the project. The ground penetrating radar results also indicated there were no areas along the longitudinal joint where the tie-bars were either too close to the pavement surface or missing.

description: Photon correlation spectroscopy (PCS) is based on measuring the temporal correlation of the light intensity scattered by the investigated sample. A typical setup requires a temporally coherent light source. Here, we show that a short-coherence light source can be used as well, provided that its coherence properties are suitably modified. This results in a "skewed-coherence" light beam allowing that restores the coherence requirements. This approach overcomes the usual need for beam filtering, which would reduce the total brightness of the beam.

description: We study the emission patterns and light curves of gamma-rays in the pulsar magnetosphere with a current-induced magnetic field perturbation. Based on the solution of a static dipole with the magnetic field induced by some currents (perturbation field), we derive the solutions of a static as well as a retarded dipole with the perturbation field in the Cartesian coordinates. The static (retarded) magnetic field can be expressed as the sum of pure static (retarded) dipolar magnetic field and the static (retarded) perturbation field. We use the solution of the retarded magnetic field to investigate the influence of the perturbation field on the emission patterns and light curves, and we apply the perturbed solutions to calculate the gamma-ray light curves for the case of the Vela pulsar. We find out that the perturbation field induced by the currents will change the emission patterns and then light curves of gamma-rays, especially for a larger perturbation field. Our results indicate that the perturbation field created by the outward-flowing (inward-flowing) electrons (positrons) can decrease the rotation effect on the magnetosphere and makes emission pattern appear to be more smooth relative to that of the pure retarded dipole, but the perturbation field created by the outward-flowing (inward-flowing) positrons (electrons) can make the emission pattern less smooth.

Пренатальное введение ганглерона беременным самкам крыс на 9-11 и 12-14 дни гестации нарушало способности как к приобретению, так и к воспроизведению условного рефлекса активного избегания у половозрелых самцов из потомства этих самок. В аналогичной ситуации метамизил оказывал негативный эффект только на процесс воспроизведения условного рефлекса активного избегания. Таким образом, долговременный негативный эффект холинотропных соединений на процессы обучаемости и памяти у половозрелого потомства может реализоваться посредством как М-, так и Н-холинергических механизмов развивающегося мозга.

description: In order to understand the material dependence of $T_c$ within the single-layered cuprates, we study a two-orbital model that considers both $d_{x^2-y^2}$ and $d_{z^2}$ orbitals. We reveal that a hybridization of $d_{z^2}$ on the Fermi surface substantially affects $T_c$ in the cuprates, where the energy difference $ΔE$ between the $d_{x^2-y2}$ and $d_{z^2}$ orbitals is identified to be the key parameter that governs both the hybridization and the shape of the Fermi surface. A smaller $ΔE$ tends to suppress $T_c$ through a larger hybridization, whose effect supersedes the effect of diamond-shaped (better-nested) Fermi surface. The mechanism of the suppression of d-wave superconductivity due to $d_{z^2}$ orbital mixture is clarified from the viewpoint of the ingredients involved in the Eliashberg equation, i.e., the Green's functions and the form of the pairing interaction described in the orbital representation. The conclusion remains qualitatively the same if we take a three-orbital model that incorporates Cu 4s orbital explicitly, where the 4s orbital is shown to have an important effect of making the Fermi surface rounded. We have then identified the origin of the material and lattice-structure dependence of $ΔE$, which is shown to be determined by the energy difference $ΔE_d$ between the two Cu3d orbitals (primarily governed by the apical oxygen height), and the energy difference $ΔE_p$ between the in-plane and apical oxygens (primarily governed by the interlayer separation $d$).

description: When developing a safety-critical system it is essential to obtain an assessment of different design alternatives. In particular, an early safety assessment of the architectural design of a system is desirable. In spite of the plethora of available formal quantitative analysis methods it is still difficult for software and system architects to integrate these techniques into their every day work. This is mainly due to the lack of methods that can be directly applied to architecture level models, for instance given as UML diagrams. Also, it is necessary that the description methods used do not require a profound knowledge of formal methods. Our approach bridges this gap and improves the integration of quantitative safety analysis methods into the development process. All inputs of the analysis are specified at the level of a UML model. This model is then automatically translated into the analysis model, and the results of the analysis are consequently represented on the level of the UML model. Thus the analysis model and the formal methods used during the analysis are hidden from the user. We illustrate the usefulness of our approach using an industrial strength case study.

description: MS5 aims to produce issue reports of how copyright exceptions and other permitted uses are understood and applied by documentary film makers and immersive digital heritage practitioners in the Netherlands and the UK. For this purpose, transcriptions or written accounts were made of the four online workshops that were undertaken for MS3. On the basis of these transcriptions and accounts, four issue reports were produced that describe the most pressing copyright issues that documentary film makers and immersive digital heritage practitioners face when making documentary films or creating immersive experiences, taken into account the existing copyright exceptions and other permitted uses in the Netherlands and the UK. These four issue reports have been directly and fully integrated in D4.10 – Issue reports on how copyright exceptions and other permitted uses that are relevant for documentary filmmakers and immersive digital heritage practitioners are understood in the Netherlands and the UK. As the executive summary of D4.10 explains, the issue reports offer an overview of the issues identified and discussed by the communities being examined in relation to copyright and the lawful reuse of audiovisual materials. The findings of the four online workshops – one for each community in the two jurisdictions under consideration – are systematised in each of the four issue reports contained in D4.10. Each issue report describes the creative and cultural practice of the workshops’ participants and the core copyright-related concerns they identified. The main points discussed by participants under each area of concern are reported. In addition to the four issue reports, D4.10 provides a snapshot of the copyright exceptions and limitations in UK and Dutch law which may cover the uses of protected content discussed by participants. Finally, D4.10 encompasses conclusive remarks and the next steps of the project.

description: The VERITAS telescope array has been operating smoothly since 2007, and has detected gamma-ray emission above 100 GeV from 40 astrophysical sources. These include blazars, pulsar wind nebulae, supernova remnants, gamma-ray binary systems, a starburst galaxy, a radio galaxy, the Crab pulsar, and gamma-ray sources whose origin remains unidentified. In 2009, the array was reconfigured, greatly improving the sensitivity. We summarize the current status of the observatory, describe some of the scientific highlights since 2009, and outline plans for the future.

Abstract Eftrenonacog alfa (Alprolix® ) is an extended half-life recombinant factor IX (rFIX)-Fc fusion protein (hereafter referred to as rFIXFc). Administered as an intravenous bolus, it is approved for prophylactic use and the treatment of bleeding in patients with haemophilia B in various countries worldwide, including those of the EU, as well as the USA. In multinational, phase III trials, rFIXFc was effective for the prophylaxis, perioperative management or on-demand treatment of bleeding in male patients with severe haemophilia B regardless of age and irrespective of whether or not they had been previously treated with FIX replacement products. Prophylactic efficacy was maintained over the longer term (up to 5 years) in previously treated patients. rFIXFc effectiveness in the real-world setting is supported by results of prospective studies, as well as the outcomes of several retrospective trials. rFIXFc was well tolerated in clinical trials in previously treated and untreated children adolescents and/or adults with severe haemophilia B. Thus, rFIXFc continues to represent a useful treatment option among the haemophilia B patient population. © Springer Nature Switzerland AG 2023
Low-energy dipole strength and the critical case of 48Ca

description: Recent theoretical work has not led to a consensus regarding the nature of the low-energy E1 strength in the 40,44,48Ca isotopes, for which high-resolution (gamma,gamma') data exist. Here we revisit this problem using the first-order quasi-particle random-phase approximation (QRPA) and different interactions. First we examine all even Ca isotopes with N=14-40. All isotopes are predicted to undergo dipole transitions at low energy, of large and comparable isoscalar strength but of varying E1 strength. Provided a moderate and uniform energetic shift is introduced to the results, QRPA with the Gogny D1S interaction is able to account for the (gamma,gamma') data, because, up to N=28, it yields a rather pure isoscalar oscillation. A neutron-skin oscillation is anticipated for N larger or equal to 30. This contradicts existing predictions that 44,48Ca develop a neutron-skin mode. Which theoretical result is correct cannot be resolved conclusively using the available data. We propose that alpha-scattering, possibly followed by an electroexcitation experiment, could resolve the situation and thereby help to improve the different models aspiring to describe reliably the low-energy dipole strength of nuclei.

Nucleon Resonances with Hidden Charm in Coupled-Channel Models

description: The model dependence of the predictions of nucleon resonances with hidden charm is investigated. We consider several coupled-channel models which are derived from relativistic quantum field theory by using (1) a unitary transformation method, and (2) the three-dimensional reductions of Bethe-Salpeter Equation. With the same vector meson exchange mechanism, we find that all models give very narrow molecular-like nucleon resonances with hidden charm in the mass range of 4.3 GeV $ < M_R < $ 4.5 GeV, in consistent with the previous predictions.

Quantifying mixed-state quantum entanglement by optimal entanglement witness

description: We develop an approach of quantifying entanglement in mixed quantum states by the optimal entanglement witness operator. We identify the convex set of mixed states for which a single witness provides the exact value of an entanglement measure, and show that the convexity, properties, and symmetries of entanglement or of a target state considerably fix the form of the optimal witness. This greatly reduces difficulty in computing and experimentally determining entanglement measures. As an example, we show how to experimentally quantify bound entanglement in four-qubit noisy Smolin states and three-qubit Greenberger-Horne-Zeilinger (GHZ) entanglement under white noise. For general measures and states, we provide a numerical method to efficiently optimize witness.

description: Most of our knowledge about star formation is based on studies of low-mass stars, whereas very little is known about the properties of the circumstellar material around young and embedded intermidiate-mass T Tauri stars (IMTTSs). We present an analysis of the excitation and accretion properties of the young IMTTS DK Cha. The nearly face-on configuration of this source allows us to have direct access to the star-disk system through the excavated envelope and outflow cavity. Based on LR optical and IR spectroscopy obtained with SofI/EFOSC2 on the NTT we derive the spectrum of DK Cha from ~0.6 to 2.5 μm. From the detected lines we probe the conditions of the gas that emits the HI IR emission lines. In addition, we derive the mass accretion rate (Macc) from the relationships that connect the luminosity of the Brγ and Paβ lines with the accretion luminosity (Lacc). The observed optical/IR spectrum is extremely rich in forbidden and permitted atomic and molecular emission lines, which makes this source similar to very active low-mass T Tauri stars. Some of the permitted emission lines are identified as being excited by fluorescence. We derive Brackett decrements and compare them with different excitation mechanisms. The Paβ/Brγ ratio is consistent with optically thick emission in LTE at a temperature of ~3500 K, originated from a compact region of ~5 Rsun in size: but the line opacity decreases in the Br lines for high quantum numbers n_{up}. A good fit to the data is obtained assuming an expanding gas in LTE, with an electron density at the wind base of ~10^13 cm-3. In addition, we find that the observed Brackett ratios are very similar to those reported in previous studies of low-mass CTTSs and Class I sources, indicating that these ratios are not dependent on masses and ages. Finally, Lacc~9 Lsun and Macc~3x10-7 Msun/yr values were found.

description: We study two player reachability-price games on single-clock timed automata. The problem is as follows: given a state of the automaton, determine whether the first player can guarantee reaching one of the designated goal locations. If a goal location can be reached then we also want to compute the optimum price of doing so. Our contribution is twofold. First, we develop a theory of cost functions, which provide a comprehensive methodology for the analysis of this problem. This theory allows us to establish our second contribution, an EXPTIME algorithm for computing the optimum reachability price, which improves the existing 3EXPTIME upper bound.

description: As alternatives to conventional metals, new plasmonic materials offer many advantages in the rapidly growing fields of plasmonics and metamaterials. These advantages include low intrinsic loss, semiconductor-based design, compatibility with standard nanofabrication processes, tunability, and others. Transparent conducting oxides such as Al:ZnO, Ga:ZnO and indium-tin-oxide (ITO) enable many high-performance metamaterial devices operating in the near-IR. Transition-metal nitrides such as TiN or ZrN can be substitutes for conventional metals in the visible frequencies. In this paper we provide the details of fabrication and characterization of these new materials and discuss their suitability for a number of metamaterial and plasmonic applications.

description: We present the scheme that allows for efficient calculations of forces in the framework of pseudopotential self-interaction corrected (pSIC) formulation of the density functional theory. The scheme works with norm conserving and also with ultrasoft pseudopotentials and has been implemented in the plane-wave basis code {\sc quantum espresso}. We have performed tests of the internal consistency of the derived expressions for forces considering ZnO and CeO$_2$ crystals. Further, we have performed calculations of equilibrium geometry for LaTiO$_3$, YTiO$_3$, and LaMnO$_3$ perovskites and also for Re and Mn pairs in silicon. Comparison with standard DFT and DFT+U approaches shows that in the cases where spurious self-interaction matters, the pSIC approach predicts different geometry, very often closer to the experimental data.

Group analysis of an ideal plasticity model

description: In this paper, we study the Lie point symmetry group of a system describing an ideal plastic plane flow in two dimensions in order to find analytical solutions of the system. The infinitesimal generators that span the Lie algebra for this system are obtained, six of which are original to this paper. We completely classify the subalgebras of codimension one and two into conjugacy classes under the action of the symmetry group. We apply the symmetry reduction method in order to obtain invariant and partially invariant solutions. These solutions are of algebraic, trigonometric, inverse trigonometric and elliptic type. Some solutions, depending on one or two arbitrary functions of one variable, have also been found. In some cases, the shape of a potentially feasible extrusion die corresponding to the solution is deduced. These tools could be used to curve and undulate rectangular rods or slabs, or to shape a ring in an ideal plastic material.
