description: Current noise in superconductor-normal metal-superconductor (SNS) junctions is calculated within the scattering theory of multiple Andreev reflections (MAR). It is shown that the noise exhibits subharmonic gap singularities at $eV=2Δ/n$, $n=1,2,... $ both in single-mode junctions with arbitrary transparency $D$ and in multi-mode disordered junctions. The subharmonic structure is superimposed with monotonic increase of the effective transferred charge $q^*=S_I(0)/2I$ with decreasing bias voltage. Other features of the noise include a step-like increase of $q^*$ in junctions with small $D$, and a divergence $S_I(0) \propto V^{-1/2}$ at small voltages and excess noise $S_{ex} = 2eI_{ex}$, where $I_{ex}$ is the excess current, at large voltages, in junctions with diffusive transport.

description: Tho-photon Rabi oscillations hold potential for quantum computing and quantum information processing, because during a Rabi cycle a pair of entangled photons may be created. We theoretically investigate the onset of this phenomenon in a heterodimer comprising a semiconductor quantum dot strongly coupled to a metal nanoparticle. Two-photon Rabi oscillations in this system occur due to a coherent two-photon process involving the ground-to-biexciton transition in the quantum dot. The presence of a metal nanoparticle nearby the quantum dot results in a self-action of the quantum dot via the metal nanoparticle, because the polatization state of the latter depends on the quantum state of the former. The interparticle interaction gives rise to two principal effects: (i) - enhancement of the external field amplitude and (ii) - renormalization of the quantum dot's resonance frequencies and relaxation rates of the off-diagonal density matrix elements, both depending on the populations of the quantum dot's levels. Here, we focus on the first effect, which results in interesting new features, in particular, in an increased number of Rabi cycles per pulse as compared to an isolated quantum dot and subsequent growth of the number of entangled photon pairs per pulse. We also discuss the destructive role of radiative decay of the excitonic states on two-photon Rabi oscillations for both an isolated quantum dot and a heterodimer.

description: Soil health is defined through soil indicators, which are assessed using targets and/or thresholds. The challenge is that targets and thresholds are highly site-, managementand climate-specific, and there is not yet a validated assessment system with that level of detail.

With policies worldwide being established to promote soil health, there is an urgent need for the development of a system to assess soils.

We explored four approaches to setting targets and thresholds. Based on stakeholder feedback of the approaches, collected in two webinars (EJP SOIL 2023) and case studies of three approaches, we developed a framework that facilitates both choosing the most appropriate target/threshold method for a given context, and using targets and thresholds to promote soil health.

description: The uncertainty principle, applied naively to the test masses of a laser-interferometer gravitational-wave detector, produces a Standard Quantum Limit (SQL) on the interferometer's sensitivity. It has long been thought that beating this SQL would require a radical redesign of interferometers. However, we show that LIGO-II interferometers, currently planned for 2006, can beat the SQL by as much as a factor two over a bandwidth Δf \sim f, if their thermal noise can be pushed low enough. This is due to dynamical correlations between photon shot noise and radiation-pressure noise, produced by the LIGO-II signal-recycling mirror.

description: LiDAR SLAM has become one of the major localization systems for ground vehicles since LiDAR Odometry And Mapping (LOAM). Many extension works on LOAM mainly leverage one specific constraint to improve the performance, e.g., information from on-board sensors such as loop closure and inertial state; prior conditions such as ground level and motion dynamics. In many robotic applications, these conditions are often known partially, hence a SLAM system can be a comprehensive problem due to the existence of numerous constraints. Therefore, we can achieve a better SLAM result by fusing them properly. In this paper, we propose a hybrid LiDAR-inertial SLAM framework that leverages both the on-board perception system and prior information such as motion dynamics to improve localization performance. In particular, we consider the case for ground vehicles, which are commonly used for autonomous driving and warehouse logistics. We present a computationally efficient LiDAR-inertial odometry method that directly parameterizes ground vehicle poses on SE(2). The out-of-SE(2) motion perturbations are not neglected but incorporated into an integrated noise term of a novel SE(2)-constraints model. For odometric measurement processing, we propose a versatile, tightly coupled LiDAR-inertial odometry to achieve better pose estimation than traditional LiDAR odometry. Thorough experiments are performed to evaluate our proposed method's performance in different scenarios, including localization for both indoor and outdoor environments. The proposed method achieves superior performance in accuracy and robustness.
Particle-laden thin-film flow in helical channels with arbitrary shallow cross-sectional shape

description: Particle-laden flows in helical channels are of interest for their applications in spiral particle separators used in the mining and mineral processing industries. In this paper, we extend the previous work of Lee, Stokes, Bertozzi (2013) by studying thin-film flows of mono-disperse particle-laden fluid in helically-wound channels of arbitrary centreline curvature and torsion, and arbitrary cross-sectional shape. In the case where the particles are uniformly distributed through the depth of the film, significant analytic progress can be made: the governing equations reduce to a single nonlinear ordinary differential equation, which is readily integrated numerically to obtain the solution subject to appropriate boundary conditions. Motivated by possible application to the design of spiral separators, we consider the effects of changing the channel centreline geometry, the cross-sectional shape and the particle density on the resulting flows and the radial distribution of particles. Our results support the findings in Arnold, Stokes, Green (2016) regarding the effect of channel centreline geometry and cross-sectional shape on flows in particle-free regions. In particle-rich regions, similar effects are seen, although the primary velocity is lower due to increased effective mixture viscosity. \ys{Of key interest, is the effect of channel geometry on the focusing of the particles, for given fluxes of fluid and particles. We find that introducing a trench into the channel cross-section, a feature often used in commercial spiral particle separators, leads to smaller radial width of the particle-rich region, i.e. sharper focusing of the particles, which is consistent with experiments showing that channel geometry influences particle separation in a spiral separator.

We present initial results of single-mode studies in two and three dimensions. Our results indicate that three-dimensional instabilities grow significantly faster than two-dimensional instabilities and that grid resolution can have a significant effect on instability growth rates. We also find that unphysical diffusive mixing occurs at the fluid interface, particularly in poorly resolved simulations.

description: The pressure-temperature phase diagram of a one-component system, with particles interacting through a spherically symmetric pair potential in two dimensions is studied. The interaction consists of a hard core plus an additional repulsion at low energies. It is shown that at zero temperature, instead of the expected isostructural transition due to core collapse occurring when increasing pressure, the system passes through a series of ground states that are not triangular lattices. In particular, and depending on parameters, structures with squares, chains, hexagons and even quasicrystalline ground states are found. At finite temperatures the solid-fluid coexistence line presents a zone with negative slope (which implies melting with decreasing in volume) and the fluid phase has a temperature of maximum density, similar to that in water.

description: We suggest that Bipolar H{\sc ii} Regions may be the aftermath of collisions between clouds. Such a collision will produce a shock-compressed layer, and a star cluster can then condense out of the dense gas near the centre of the layer. If the clouds are sufficiently massive, the star cluster is likely to contain at least one massive star, which emits ionising radiation, and excites an H{\sc ii} region, which then expands, sweeping up the surrounding neutral gas. Once most of the matter in the clouds has accreted onto the layer, expansion of the H{\sc ii} Region meets little resistance in directions perpendicular to the mid-plane of the layer, and so it expands rapidly to produce two lobes of ionised gas, one on each side of the layer. Conversely, in directions parallel to the mid-plane of the layer, expansion of the H{\sc ii} Region stalls due to the ram-pressure of the gas that continues to fall towards the star cluster from the outer parts of the layer; a ring of dense neutral gas builds up around the waist of the Bipolar H{\sc ii} Region, and may spawn a second generation of star formation. In this paper we present a dimensionless model for the flow of ionised gas in a Bipolar H{\sc ii} Region created according to the above scenario, and predict the characteristics of the resulting freefree continuum and recombination-line emission. This dimensionless model can be scaled to the physical parameters of any particular system. Our intention is that these predictions will be useful in testing the scenario outlined above, and thereby providing indirect support for the role of cloud/cloud collisions in triggering star formation.

description: Magnon spin currents in the ferrimagnetic garnet Tb3Fe5O12 with 4f electrons were examined through the spin-Seebeck effect and neutron scattering measurements. The compound shows a magnetic compensation, where the spin-Seebeck signal reverses above and below Tcomp = 249.5(4) K. Unpolarized neutron scattering unveils two major magnon branches with finite energy gaps, which are well-explained in the framework of spin-wave theory. Their temperature dependencies and the direction of the precession motion of magnetic moments, i.e. magnon polarization, defined using polarized neutrons, explain the reversal at Tcomp and decay of the spin-Seebeck signals at low temperatures. We illustrate an example that momentum- and energy-resolved microscopic information is a prerequisite to understanding the magnon spin current.

description: We study a system of two Tomonaga-Luttinger models coupled by a small transverse hopping (a two-chain ladder). We use Abelian and non-Abelian bosonisation to show that the strong coupling regime at low energies can be described by an SO(5)$_1$ WZW model (or equivalently 5 massless Majorana fermions) deformed by symmetry breaking terms that nonetheless leave the theory critical at T=0. The SO(5) currents of the theory comprise the charge and spin currents and linear combinations of the so-called pi operators (S.C. Zhang, Science 275, 1089 (1997)) which are local in terms both of the original fermions and those of the effective theory. Using bosonisation we obtain the asymptotic behaviour of all correlation functions. We find that the 5 component ``superspin'' vector has power law correlations at T=0; other fermion bilinears have exponentially decaying correlations and the corresponding tendencies are suppressed. Conformal field theory also allows us to obtain the energies, quantum numbers, and degeneracies of the low-lying states and fit them into deformed SO(5) multiplets.

description: We consider the influence of Faraday rotation in chaotic magnetic field on the intensity and linear polarization of multiple scattered radiation. All fluctuations are assumed as Gaussian type and isotropic. The values of magnetic field are less than $10^5$Gauss. In this case the parameter $ ω_B/ω=(eB/m_ec)/ω\simeq 0.93\cdot 10^{-8}λ$($μ$m)$B($G$)$ is small and the radiation scatterings are the usual scatterings on free electrons. Only the Faraday rotation influences on the intensity and polarization of radiation. We consider the Milne problem in the electron magnetized atmosphere without the mean magnetic field. We found that chaotic magnetic field does not increase the number of H-functions, describing the Milne problem. There are four H-functions as in the Milne problem for non-magnetized case. The calculations demonstrate that the polarization of outgoing radiation diminishes strongly with the increasing of the level of magnetic fluctuations. The calculations can be used for estimations of inclination angle $i$ of accretion discs and the level of magnetic fluctuations.

The reason for this overestimation is discussed.

description: The low-temperature driven or thermally activated motion of several condensed matter systems is often modeled by the dynamics of interfaces (co-dimension-1 elastic manifolds) subject to a random potential. Two characteristic quantitative features of the energy landscape of such a many-degree-of-freedom system are the ground-state energy and the magnitude of the energy barriers between given configurations. While the numerical determination of the former can be accomplished in time polynomial in the system size, it is shown here that the problem of determining the latter quantity is NP-complete. Exact computation of barriers is therefore (almost certainly) much more difficult than determining the exact ground states of interfaces.

description: Processes of diffusion of As and P atoms in InP and InAs, and atomic and energy structure of group-V vacancies and interstitial P and As atoms in InP and InAs have been investigated using density functional theory. Formation energies of group-V vacancies in InP and InAs and P and As interstitial atoms in InP and InAs have been calculated with hybrid functional. The main types of migration jumps have been determined, and the energy favorable migration paths and migration barriers of As and P atoms diffusion in InP and InAs via vacancies and interstitial atoms have been calculated using climbing image nudged elastic band method. In the case of diffusion of As and P atoms in InP and InAs via interstitial atoms the diffusion process occurs via indirect interstitial mechanism. The migration energy barriers for the vacancy diffusion mechanism are 1.5-2.0 eV, the migration energy barriers for the interstitialcy mechanism are 0.3-0.6 eV. The interstitial atoms have higher formation energies compared to the formation energies of the vacancies, and total activation energies of the diffusion are comparable for the vacancy and interstitialcy mechanisms. The obtained results will be useful for modeling of the diffusion processes in semiconductor structures based on InP and InAs.

description: A star forms when a cloud of dust and gas collapses. It is generally believed that this collapse first produces a flattened rotating disk, through which matter is fed onto the embryonic star at the center of the disk. When the temperature and density at the center of the star pass a critical threshold, thermonuclear fusion begins. The remaining disk, which can still contain up to 0.3 times the mass of the star, is then sculpted and eventually dissipated by the radiation and wind from the newborn star. Unfortunately this picture of the structure and evolution of the disk remains speculative because of the lack of morphological data of sufficient resolution and uncertainties regarding the underlying physical processes. Here we present resolved images of a young star, LkHa 101 in which the structure of the inner accretion disk is resolved. We find that the disk is almost face-on, with a central gap (or cavity) and a hot inner edge. The cavity is bigger than previous theoretical predictions, and we infer that the position of the inner edge is probably determined by sublimation of dust grains by direct stellar radiation, rather than by disk reprocessing or the viscous heating processes as usually assumed.

 Notes. This species was originally described as Dacus (Asiadacus) perpusillus Drew, 1971 and later reassigned as Bactrocera (Sinodacus) perpusilla (Drew) by Drew (1989). More recently, it was transferred to genus Zeugodacus, as Z.

A close morphological examination of fresh specimens collected by the author in New Caledonia in 2019 clearly shows that this species belongs to genus Dacus and subgenus Neodacus, as defined by Drew and Romig (2013, 2022), further confirmed by genetic data (Doorenweerd et al. 2020). I am therefore reassigning this species as Dacus (Neodacus) perpusillus Drew.

description: Selenium (Se) is an essential nutrient for humans and animals, but is toxic at high concentrations in leaves. It is chemically similar to phosphorus (P), an essential plant macronutrient. The objective of this pot experiment was to investigate the effects of P- and Se-application rate on alfalfa growth and P and Se uptake in loessial soil, and reveal the changing processes of soil P and Se fractions. The results indicated that Se concentration in alfalfa was significantly influenced by the interaction of P- and Se-application rate. In the loessial soil, an optimal P- and Se-application rate is 5 mg kg−1 and 2 mg kg−1, respectively for plant growth and the maximum P and Se accumulation in alfalfa. Besides, concentrations of exchangeable Se and organic-matter-bound Se in soil decreased, as the P-application rate increased, whereas concentrations of soluble Se and iron oxide-bound Se increased. The addition of P fertilizer reduced soil pH, affecting the changing processes of soil P and Se fractions, thus promoting the activation of Fe-P and the transformation of exchangeable Se to iron oxide-bound Se. These findings will help in understanding of forage P and Se accumulation and provide the guide for cultivating Se-enriched forage.

Preparedness for education to Rohingya refugee children in Bangladesh: potentials and challenges to citizenship education
Creators: name: Hossain, A N M Zakir
Publisher: name: JSSE - Journal of Social Science Education
Year: 2021

description: • • Identify the existing opportunities and challenges for the education of refugee children • Citizenship and civic education of refugee children is seen as an asset to reduce inequality for their future livelihoods • What significant initiatives were launched to support refugee children in developing key competence • Explores how to respond more creatively and collaboratively to support the refugee children education in this critical situation • How governmental and non-governmental organizations are willing to support their education process Purpose: The number of Rohingya refugee children in Bangladesh is more than fifty percent who are out of formal education since the persecution and the mass atrocities which started in 2017 by the Myanmar government in Rakhine. They need education as their rights and means of future livelihoods that can contribute to both the refugee and host society in the future. Thus, perceptions into formal education can help refugee children to reduce inequality in general and build capacity from a socio-economic and moral perspective. Methodology: The article endeavors to document the existing pros and cons of Rohingya refugee children's education in Bangladesh. Therefore, the study offers insights examining the existing framework of education for citizenship and civic education of refugee children as well as the opportunities in the future in terms of quality, quantity, and level of education. In direction to investigate the education process in the context of refugee children the study primarily based on secondary sources of data to grasp the conclusion. Findings: The results indicate that limited initiative has been taken by the host country and other supporting regional and global non-state actors for Rohingya refugee children. However, the number of education centers need to increase immediately as many more children are out of formal education. In addition, it is crucial to start a junior schooling system for teenagers as well as recruit trained and efficient teachers with a structured curriculum. Furthermore, the government of Bangladesh is adamant to open a formal education system, though the international partners are continuously urging for it which is also crucial for education and citizenship education with a well-structured curriculum. The teachers and students need additional support in terms of training and motivation to keep the process ongoing which is found more challenging for both of them while the host country’s schooling shutdown since March 2020. Limitations: Findings of this study on refugee children's education in Bangladesh cannot be generalized to another context.

Year: 2021

description: • Migrant and refugee youth face complex challenges pertaining to educational and social inclusion in Europe and international contexts. • Global Citizenship Education (GCE) has gained increased prevalence as an educational response to globalizing processes such as forced migration and resulting cultural diversity. • It is argued that a critical and decentered model of GCE can be applied as an inclusive educational response to refugee youth within national educational settings. • Visual and participatory educational practices emphasizing the role of the teacher as a 'visitor' are presented and discussed. Purpose: To explore the role and possibilities of Global Citizenship Education (GCE) in attending to neglected aspects of inclusive education when responding to forced youth migration in Europe. Approach: We discuss different approaches to GCE within the literature, their implications for refugee students within national educational settings and give an example of how critical GCE can be practiced in education. Finding: Drawing on theoretical work of John Dewey and Hannah Arendt, in conjunction with more recent theoretical work on global citizenship within education, we argue that a critical and decentered model of GCE is important to support processes of inclusion and citizenship for refugee youth within national educational settings. Implications: We apply and discuss the suggested theoretical approach in relation to pedagogical practices developed as a part of an ongoing research project on irregular processes of inclusion and citizenship for migrant and refugee youth in Iceland, Norway, and the UK.

description: Rivers are affected by changes in catchment land-use and other modifications to their channel, floodplains and riparian zones. Such changes can affect biodiversity downstream, and specialist river birds might indicate the effects across multiple scales and through different ecological pathways. The risks of catchment-scale effects on rivers are especially acute in the Himalayan mountains, where the world’s greatest diversity of river birds occupies one of the most rapidly changing riverine environments on Earth. Here, we use multivariate analysis on data collected over two years to investigate the distribution of this group of birds in relation to natural and anthropogenic variations in riverine habitats along one of the major headwaters of the Ganges. River bird distribution was linked to channel character, bank morphology, aspects of river flow and land use. Riverine specialists were associated significantly with the least modified reaches characterised by faster flows, exposed bedrocks, banks with pebbles, boulders with more intact riverine forests. Our data provide evidence from which to develop specialist river birds as cost-effective indicators of human impacts on river ecosystems, but further work is needed to separate the effects of natural and anthropogenic influences. Such work could also guide conservation action to help balance the exploitation of catchment ecosystem services with the protection of river biodiversity.
Alternating Kinetics of Annihilating Random Walks Near a Free Interface

description: The kinetics of annihilating random walks in one dimension, with the half-line x>0 initially filled, is investigated. The survival probability of the nth particle from the interface exhibits power-law decay, S_n(t)~t^{-alpha_n}, with alpha_n approximately equal to 0.225 for n=1 and all odd values of n; for all n even, a faster decay with alpha_n approximately equal to 0.865 is observed. From consideration of the eventual survival probability in a finite cluster of particles, the rigorous bound alpha_1<1/4 is derived, while a heuristic argument gives alpha_1 approximately equal to 3 sqrt{3}/8 = 0.2067.... Numerically, this latter value appears to be a stringent lower bound for alpha_1. The average position of the first particle moves to the right approximately as 1.7 t^{1/2}, with a relatively sharp and asymmetric probability distribution.

description: • The study examined teachers’, parents’ and students’ attitudes toward controversial political issues (CPI). • A Random stratified sample of 501 adults and 201 high school students completed questionnaires. • Respondents had little confidence in teachers’ ability to conduct CPI discussions in classrooms. • Students reported low incidents of CPI discussions in classrooms. • Support for CPI discussions differed according to specific topics. Purpose: Many argue for the benefits of controversial political issues (CPI) discussions but little is known about teachers’, parents’, and students’ attitudes toward CPI. The present study explored these attitudes, as well as attitudes towards specific controversial topics, and how they relate to socio-demographic variables. Design/methodology/approach: Quantitative cross-sectional methodology was employed using questionnaires to collect data. Random stratified sampling was used to obtain a representative sample of 501 Jewish Israeli adults, including 70 teachers, and 201 Jewish Israeli 10th-12th grade students. Findings: Respondents, including the teachers themselves, had little confidence in teachers’ ability to conduct CPI discussions in classrooms. Students reported low incidents of CPI discussions in classrooms, and that they are mostly held by homeroom and civics teachers. Students supported CPI discussions more than adults (including teachers) and wanted teachers to disclose their opinions much more than adults did. Support for CPI discussions differed according to specific topics. Linear regression revealed that the less religious individuals are, the more left-wing, older and more educated, the more they will support CPI teaching.

description: In 1967, Whitham proposed a simplified surface water-wave model which combined the full linear dispersion relation of the full Euler equations with a weakly linear approximation. The equation he postulated which is now called the Whitham equation has recently been extended to a system of equations allowing for bi-directional propagation of surface waves. A number of different two-way systems have been put forward, and even though they are similar from a modeling point of view, these systems have very different mathematical properties. In the current work, we review some of the existing fully dispersive systems. We use state-of-the-art numerical tools to try to understand existence and stability of solutions to the initial-value problem associated to these systems. We also put forward a new system which is Hamiltonian and semi-linear. The new system is shown to perform well both with regard to approximating the full Euler system, and with regard to well posedness properties.

description: Recentely, it is shown that the quantum effects of matter determine the conformal degree of freedom of the space-time metric. This was done in the framework of a scalar-tensor theory with one scalar field. A point with that theory is that the form of quantum potential is preassumed. Here we present a scalar-tensor theory with two scalar fields, and no assumption on the form of quantum potential. It is shown that using the equations of motion one gets the correct form of quantum potential plus some corrections.
