description: We investigate the dynamics of spinning binaries of compact objects at the next-to-leading order in the quadratic-in-spin effects, which corresponds to the third post-Newtonian order (3PN). Using a Dixon-type multipolar formalism for spinning point particles endowed with spin-induced quadrupoles and computing iteratively in harmonic coordinates the relevant pieces of the PN metric within the near zone, we derive the post-Newtonian equations of motion as well as the equations of spin precession. We find full equivalence with available results. We then focus on the far-zone field produced by those systems and obtain the previously unknown 3PN spin contributions to the gravitational-wave energy flux by means of the multipolar post-Minkowskian (MPM) wave generation formalism. Our results are presented in the center-of-mass frame for generic orbits, before being further specialized to the case of spin-aligned, circular orbits. We derive the orbital phase of the binary based on the energy balance equation and briefly discuss the relevance of the new terms.

description: The monitoring of toxic vapours such as M-cymene and m-xylene from industries is a significant task using a solid-state chemical sensor. We report the structurally stable hex-star arsenene sheets (hex-star AsNS) as a base material to perceive the presence of M-cymene and m-xylene molecules. Initially, we examined the formation energy of hex-star AsNS and ensured the geometric stability. Besides, hex-star AsNS possesses an energy band gap of 1.033 eV indicating the semiconductor state. We explored the changes in the band structure and PDOS (projected density of states) spectrum of hex-star AsNS upon adsorption of M-cymene and m-xylene molecules. Also, concerning charge transfer and electron density difference studies, the electronic properties of hex-star AsNS are reconnoitered. The adsorption energy upon M-cymene and m-xylene adsorption show the physisorption of target molecules on hex-star AsNS. The outcome reveals the hex-star AsNS as an emerging material for the detection of M-cymene and m-xylene molecules.

description: This policy brief showcases a successful solution to a poor connectivity problem through the construction of an effective transport interchange network in Stoke-on-Trent – a medium-size polycentric industrial city in central England, undergoing fundamental economic restructuring and experiencing an increase in transportation demand. This decade-long project of upgrading two non-primary (non-motorway) roads around the Potteries was completed in 2006. Building on local stakeholders’ knowledge and experience in delivering this solution, this brief shows how a strategic transport interchange can make a shrinking city successful by attractively connecting the areas of work, living, shopping, and leisure. The key lesson learnt is that both external and internal connectivity is critical for making a successful city, and that providing more options for sustainable and active local travel supported by a range of facilities (cycle racks, park and rides, dedicated bus lanes) can enhance the city connectivity.

description: We use the Schwinger-Dyson equations in the presence of a thermal bath, in order to study chiral symmetry breaking in a system of massless Dirac fermions interacting through pseudo quantum electrodynamics (PQED3), in (2+1) dimensions. We show that there is a critical temperature $T_c$, below which chiral symmetry is broken, and a corresponding mass gap is dynamically generated, provided the coupling is above a certain, temperature dependent, critical value $α_c$. The ratio between the energy gap and the critical temperature for this model is estimated to be $2 π$. These results are confirmed by analytical and numerical investigations of the Schwinger-Dyson equation for the electron. In addition, we calculate the first finite-temperature corrections to the static Coulomb interaction. The relevance of this result in the realm of condensed matter systems, like graphene, is briefly discussed.

description: A series of cyclometalated platinum (II) complexes with aromatic ligands, such as pyridyl, pyrimidinyl, and pyrazolate, were investigated with theoretical calculations. To investigate the relationship between ligands with molecular orbital, molecular rigidity, electroluminescent properties, and spectroscopic properties, the electrostatic potential (ESP), density-of-states (DOS), and root mean squared displacement (RMSD) were calculated. On the basis of calculated absorption and phosphorescence data, the analysis of ‘hole’ and ‘electron’ have also been performed. From the RMSD and spin–orbit coupling (SOC) matrix elements calculations, complex 3 shows significant structural distortions on S1 state and it may be applied in thermal activation delayed fluorescence (TADF) materials. The electroluminescent properties calculations show that complex 1 is suitable for hole transport material and complex 4 can be applied to electron transport material.

description: Here we will provide a review on broadband asymmetrical multi-section Wilkinson power divider and try to identify the technical strengths as well as the weaknesses of the same. A numerical technique based on the method of least squares (MLS) was presented for the design as well as the optimization of a Wilkinson power divider for arbitrary power division between its output ports within a specified frequency bandwidth enabled by source and load impedance matching. In the paper, we will describe our optimum design of the Wilkinson power divider with the proposed MLS procedure by means of (a) full-wave simulations and (b) fabrication and measurement of two separate designs.
How smooth are particle trajectories in a $Λ$CDM Universe?

description: It is shown here that in a flat, cold dark matter (CDM) dominated Universe with positive cosmological constant ($Λ$), modelled in terms of a Newtonian and collisionless fluid, particle trajectories are analytical in time (representable by a convergent Taylor series) until at least a finite time after decoupling. The time variable used for this statement is the cosmic scale factor, i.e., the "$a$-time", and not the cosmic time. For this, a Lagrangian-coordinates formulation of the Euler-Poisson equations is employed, originally used by Cauchy for 3-D incompressible flow. Temporal analyticity for $Λ$CDM is found to be a consequence of novel explicit all-order recursion relations for the $a$-time Taylor coefficients of the Lagrangian displacement field, from which we derive the convergence of the $a$-time Taylor series. A lower bound for the $a$-time where analyticity is guaranteed and shell-crossing is ruled out is obtained, whose value depends only on $Λ$ and on the initial spatial smoothness of the density field. The largest time interval is achieved when $Λ$ vanishes, i.e., for an Einstein-de Sitter universe. Analyticity holds also if, instead of the $a$-time, one uses the linear structure growth $D$-time, but no simple recursion relations are then obtained. The analyticity result also holds when a curvature term is included in the Friedmann equation for the background, but inclusion of a radiation term arising from the primordial era spoils analyticity.

Galaxy Groups

Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)
subject: FOS: Physical sciences

description: Galaxy groups can be characterized by the radius of decoupling from cosmic expansion, the radius of the caustic of second turnaround, and the velocity dispersion of galaxies within this latter radius. These parameters can be a challenge to measure, especially for small groups with few members. In this study, results are gathered pertaining to particularly well studied groups over four decades in group mass. Scaling relations anticipated from theory are demonstrated and coefficients of the relationships are specified. There is an update of the relationship between light and mass for groups, confirming that groups with mass of a few times 10^12 Msun are the most lit up while groups with more and less mass are darker. It is demonstrated that there is an interesting one-to-one correlation between the number of dwarf satellites in a group and the group mass. There is the suggestion that small variations in the slope of the luminosity function in groups are caused by the degree of depletion of intermediate luminosity systems rather than variations in the number per unit mass of dwarfs. Finally, returning to the characteristic radii of groups, the ratio of first to second turnaround depends on the dark matter and dark energy content of the universe and a crude estimate can be made from the current observations of Omega_matter ~ 0.15 in a flat topology, with a 68% probability of being less than 0.44.

Affordances of generative AI change our perceptions of what can be possible, prompting to re-evaluate research questions, interventions, and applications in the field of educational technology. Against this backdrop, what should the focus on using data to inform teaching and learning look like? Learning analytics, an applied domain centred on data about learners, their processes, and learning artefacts, has gained traction over the last decade. The talk will take a historical perspective to position learning analytics within existing educational technology paradigms and discuss it within the context of AI, highlighting the adjacent possible for the future development.

description: In this paper the classical Euler-Bernoulli beam (CEBB) theory is reformulated utilising fractional calculus. Such generalisation is called fractional Euler-Bernoulli beams (FEBB) and results in non-local spatial description. The parameters of the model are identified based on AFM experiments concerning bending rigidities of micro-beams made of the polymer SU-8. In experiments both force as well as deflection data were recorded revealing significant size effect with respect to outer dimensions of the specimens. Special attention is also focused on the proper numerical solution of obtained fractional differential equation.

description: Shock waves are steep wave fronts that are fundamental in nature, especially in high-speed fluid flows. When a shock hits an obstacle, or a flying body meets a shock, shock reflection/diffraction phenomena occur. In this paper, we show how several longstanding shock reflection/diffraction problems can be formulated as free boundary problems, discuss some recent progress in developing mathematical ideas, approaches, and techniques for solving these problems, and present some further open problems in this direction. In particular, these shock problems include von Neumann's problem for shock reflection-diffraction by two-dimensional wedges with concave corner, Lighthill's problem for shock diffraction by two-dimensional wedges with convex corner, and Prandtl-Meyer's problem for supersonic flow impinging onto solid wedges, which are also fundamental in the mathematical theory of multidimensional conservation laws.

Pupil Engineering in a Miniaturized Fluorescent Microscopy Platform Using Multilevel Diffractive Optics

description: There is a growing enthusiasm in neuroscience and medical research towards imaging of neurons as well as interconnectivity in an effort to achieve a more complete understanding of neurological illness and eventually cognitive growth. While many existing imaging architectures successfully detect active neural tissue, fluorescence imaging through head-mounted microscopes is catching up as a standard method of imaging neural circuitry in animals. We developed a miniaturized, open-source, single-photon ‘finch-scope’ to provide for rapid prototyping in head-mounted miniscope technology. While experimentally convenient, we can say that the finch-scope and other miniscope platforms are constrained by their native depth of field and may only detect a thin layer of active neurons. In this paper, we will investigate utilizing optical phase masks also known as “Multilevel Diffractive Lenses” integrated in the Fourier plane of the finch-scope to invoke a less-diffractive Bessel point spread function. Next, we will experimentally justify the extended depth of field nature of these phase masks by imaging the axial profile of a 10μm fluorescent pinhole object with a modified finchscope.

description: The full structuration of light in the transverse plane, including intensity, phase and polarization, holds the promise of unprecedented capabilities for applications in classical optics as well as in quantum optics and information sciences. Harnessing special topologies can lead to enhanced focusing, data multiplexing or advanced sensing and metrology. Here we experimentally demonstrate the storage of such spatio-polarization-patterned beams into an optical memory. A set of vectorial vortex modes is generated via liquid crystal cell with topological charge in the optic axis distribution, and preservation of the phase and polarization singularities is demonstrated after retrieval, at the single-photon level. The realized multiple-degree-of-freedom memory can find applications in classical data processing but also in quantum network scenarios where structured states have been shown to provide promising attributes, such as rotational invariance.

description: We study the non-equilibrium dynamics of two component bosonic atoms in a one-dimensional optical lattice in the presence of spin-orbit coupling. In the Mott insulating regime, the two-component bosonic system at unity filling can be described by the quantum spin XXZ model. The atoms are initially prepared in their lower spin states. The system becomes out of equilibrium by suddenly introducing spin-orbit coupling to the atoms. The system shows the relaxation and non-stationary dynamics, respectively, in the different interaction regimes. We find that the time average of magnetization is useful to characterize the many-body dynamics. The effects of even and odd numbers of sites are discussed. Our result sheds light on non-equilibrium dynamics due to the interplay between spin-orbit coupling and atomic interactions.

The Recovery and Resilience Facility: Boosting Investment in Social Infrastructure in Europe?

description: Moving away from the austerity conditionality approach towards a new expansionary investment–led growth strategy, the Recovery and Resilient Facility represents a break with what went before and is an innovative instrument to support public investment in Europe. In particular, by placing the objectives of upward social convergence and implementation of the European Pillar of Social Rights at its core, the RRF is expected to help boost investment in social infrastructure in the EU after a decade of underinvestment. Zooming in on a sample of six countries (Austria, Belgium, Germany, Italy, Portugal and Spain), this article investigates the extent to which the social investments included in the plans are truly additional. It finds that the RRF has indeed fasted-forward the implementation of investments in social infrastructure, which would have otherwise been remained merely on paper, especially in those countries with limited fiscal capacity (Italy, Spain, Portugal but also Belgium). By contrast, in countries such as Germany and Austria, RRF social spending is used largely to replace already planned or budgeted investments. Even in the former group, however, the article shows that around one-third of the social spending is allocated to already planned or ongoing projects.

From deregulatory pressure to laissez faire: the (moderate) social implications of the EU recovery strategy
Creators: name: Rainone, Silvia
Publisher: name: Italian Labour Law e-Journal
Year: 2022

description: This article assesses the impact of the EU recovery strategy in (re)aligning the EU with the pursuit of its social objectives, including those defined in the Porto Declaration. First, the focus is on the major innovations introduced by the NextGenerationEU (NGEU) plan and SURE (a temporary instrument aimed at mitigating unemployment risks during the pandemic) in relation to the social dimension of EU integration. Elements such as the incentive for public investments, softer forms of macroeconomic and fiscal conditionality, and the valorisation of the European Pillar of Social Rights constitute fundamental differences from the approach that had characterised the euro crisis. Subsequently, however, the article shows that this greater openness of EU governance towards social and labour protection policies does not translate into a tangible strengthening of safeguards in the national recovery and resilience plans. The article then argues that achieving the EU's social objectives requires the establishment of more effective incentives, and concludes by proposing a roadmap for future reforms.

description: It will be shown in this paper that new sensitive phase based one-dimensional photonic crystal devices can be developed if existing problems can somehow be overcome. From such perspective, the major problems associated can be states ad rapid change of light intensity around the defect mode in one-dimensional systems and the effect of the substrate. Some of the techniques which are used to overcome such problems is to construct a defective one-dimensional photonic crystal in a heterostructure or an asymmetric structure. Now considering this, we can see that the phase of asymmetric one-dimensional photonic crystals along with couple defects are shown in this paper. As a immediate extension of this, a phase modulator as well as a phase switch with very high sensitivity are demonstrated.

description: Alongside examination regulations, module handbooks provide overview of a study program, including information like workload, learning goals, examinations. They provide guidance to students, but can also be a valuable information source to curriculum analytics, e.g., the identification of trends and patterns across modules, the assessment of course content coherence, and data-driven decision-making regarding curriculum design and revision. This paper introduces a tool for semi-assisted module handbook content extraction, which uses natural language processing and text mining techniques to extract all properties and relevant details from module handbooks, allowing instructors and curriculum designers to efficiently identify key information. As module handbooks between institutions may look very different, fully automated extraction is difficult and error-prone. By allowing users to verify and correct extraction results in a semi-assisted manner, higher accuracy and reliability of module data can be achieved.
The social dimension of EU economic governance after the Covid-19 pandemic: exploring new interlinkages
Creators: name: Bekker, Sonja
Publisher: name: Italian Labour Law e-Journal
Year: 2022

description: This article assesses the space for the social dimension of EU economic governance after the Covid-19 pandemic. It does so by looking at the types of instruments that are used to further European social policy. It describes how rule-based, coordination-based and monetary-based instruments are connected to different conceptualisations of European social policy and the role national actors might play, including the social partners. The different instruments are brought together in governance architectures, for example in the European Pillar of Social Rights, the European Semester, and the Recovery and Resilience Facility. Lately, monetary-based instruments have been used more often, also in order to shape European social policy. Moreover, apart from combining different instruments, the governance architectures themselves seem deliberately to be interlinked. The article ends with a provisional research agenda, proposing questions that should be addressed in order to understand how the social dimension is anchored in the wide range of governance instruments.

description: Every year, millions of students learn how to write programs. Learning activities for beginners almost always include programming tasks that require a student to write a program to solve a particular problem. When learning how to solve such a task, many students need feedback on their previous actions, and hints on how to proceed. For tasks such as programming, which are most often solved stepwise, the feedback should take the steps a student has taken towards implementing a solution into account, and the hints should help a student to complete or improve a possibly partial solution. In this talk I will give an overview of the approaches to automatic feedback and hints on programming steps and discuss our research on how to evaluate the quality of feedback and hints. I will also take the opportunity to involve the audience in some of the dilemmas we are facing.

description: The Kondo lattice model describes a quantum phase transition between the antiferromagnetic state and heavy-fermion states. Applying the dual-fermion approach, we explore possible superconductivities emerging due to the critical antiferromagnetic fluctuations. The d-wave pairing is found to be the leading instability only in the weak-coupling regime. As the coupling is increased, we observe a change of the pairing symmetry into a p-wave spin-singlet pairing. The competing superconductivities are ascribed to crossover between small and large Fermi surfaces, which occurs with formation of heavy quasiparticles.

description: Public healthcare services ought to be evenhandedly provided or accessible to any citizen. However, rural areas, having large elderly population that is traditionally vulnerable and underserved with respect to healthcare, are in the lack of healthcare infrastructures, comparing to those of urban areas. The main purpose of this paper is to investigate the level of spatial equity of public healthcare facilities for rural areas in Korea. This study analyzes the spatial equity and locational efficiency of public healthcare facilities in 80 rural areas. To evaluate the spatial equity, population of each administrative unit is transformed to a grid map using dasymetric mapping method. Service areas and population are extracted to evaluate the spatial equity, and then the locational efficiency is evaluated using the number of residents within the serviceable areas. Results showed that the whole public healthcare facilities help 91.2% of rural population and average geographic boundary of each facility covers 106.7 persons per 1km2. We also found that deviations in the locational efficiency were as much wide as they are in the spatial equity. Rural areas in Chungcheongnam-do rated the highest in the spatial equity and the locational efficiency, while rural areas in Gangwon-do rated the lowest. This study concludes with suggesting some policy issues that need to be considered in the provision of public healthcare facilities in rural areas.

description: In addition to various subject-related challenges, students face diverse organizational challenges, including the planning of their own study path while considering individual and organizational circumstances or constraints. While examination regulations usually provide an exemplary study plan, it may only fit as long as no adjustments have to be made. If students fail exams or postpone modules, an individual study plan is needed to keep track of the own study path. With growing enrolment numbers and increasing heterogeneity of study profiles and paths, staff resources in student counselling or mentoring can only provide limited support. As such, this paper presents an interactive, web-based study planning tool, which enables students to plan their individual path using a visual representation of subject areas and modules, while also highlighting module requirements and dependencies. A first evaluation provides positive feedback, a good user experience, but also feature suggestions for further development.

description: This contribution illustrates the main elements of the National Recovery and Resilience Plan presented by the Swedish government in 2022 in the context of the NextGenerationEU Action Plan. Along with an overview of its general features, this contribution focuses on the Plan’s social and labour components. It illustrates the reforms and measures the Swedish government presented in order to tackle major problems on the labour market, including inclusion of marginal groups, job training to improve skills in key professions, such as health and elder care, and to facilitate job transition, and to tackle labour shortages in key sectors such as elder care and education. The contribution also reviews the role of the social partners in dealing with the labour market effects of the Covid-19 pandemic through collective bargaining. There is also a retrospective analysis of their role in the 2008 economic crisis.

description: The circular restricted three body problem is investigated in the context of accretion and scattering processes. In our model a large number of identical non-interacting mass-less planetesimals are considered in planar case orbiting a star-planet system. This description allows us to investigate in dynamical systems approach the gravitational scattering and possible captures of the particles by the forming planetary embryo. Although the problem serves a large variety of complex motion, the results can be easily interpreted because of the low dimensionality of the phase space. We show that initial conditions define isolated regions of the disk, where accretion or escape of the planetesimals occur, these have, in fact, a fractal structure. The fractal geometry of these "basins" implies that the dynamics is very complex. Based on the calculated escape rates and escape times, it is also demonstrated that the planetary accretion rate is exponential for short times and follows a power-law for longer integration. A new numerical calculation of the maximum mass that a planet can reach (described by the expression of the isolation mass) is also derived.

description: The combination of Virtual Reality (VR) and eye tracking allows to analyze how students use the presented VR content for learning. Here, we propose a novel approach to analyze eye tracking data in VR, even if no access to the VR software source code is given. This proof-of-concept leverages image classification methods to identify objects that captured the students' attention in VR. The method allows analysis of individual learning strategies and correlate those to individual learning outcomes.

Infinite circumference limit of conformal field theory

description: We argue that an infinite circumference limit can be obtained in 2-dimensional conformal field theory by adopting $L_0-(L_1+L_{-1})/2$ as a Hamiltonian instead of $L_0$. The theory obtained has a circumference of infinite length and hence exhibits a continuous and heavily degenerated spectrum as well as the continuous Virasoro algebra. The choice of this Hamiltonian was inspired partly by the so-called sine-square deformation, which is found in the study of a certain class of quantum statistical systems. The enigmatic behavior of sine-square deformed systems such as the sharing of their vacuum states with the closed boundary systems can be understood by the appearance of an infinite circumference.

description: The wide availability of light-emitting diode (LED)-based light sources makes possible the use of visible light communication (VLC) for both indoor and vehicular wireless connectivity. Earlier works on VLC have predominantly used photodetectors as receivers. It is also possible to utilize solar panels as receivers. In this paper, we present an experimental performance evaluation of a vehicular VLC system with a truck headlight as the transmitter and a solar panel as the receiver. First, we characterize the frequency response of two different solar panels and measure their bandwidth. Then, we present the performance of the vehicular VLC system in terms of data rate, signal-to-noise ratio (SNR), and eye diagrams

National Recovery and Resilience Plan: France

description: France’s Recovery and Resilience Plan was submitted to the European Commission on 28 April 2021, in accordance with Art. 18 of Regulation (EU) 2021/241 establishing the Recovery and Resilience Facility. Being a part of a broader national recovery plan named ‘France Relance’, it consists of 20 reforms and 71 investments in three main areas: green transition, digital transition, and social and territorial cohesion. With particular regard to social issues, the French plan puts a strong focus on youth labour market integration and health care, while being relatively poor in measures relevant to labour law and social protection. Overall, although the plan demonstrates a certain openness towards social growth, it also contains some austerity-driven reforms, especially in the fields of unemployment insurance and retirement pensions, thereby confirming the (still) strong link between social policies and financial sustainability.
