description: Two broad charmed mesons, the D_0^* and D_1', have recently been observed. We examine the quark model predictions for the D_0^* and D_1' properties and discuss experimental measurements that can shed light on them. We find that these states are well described as the broad, j=1/2 non-strange charmed P-wave mesons. Understanding the D_0^* and D_1' states can provide important insights into the D_{sJ}^*(2317), D_{sJ}(2460) states whose unexpected properties have led to renewed interest in hadron spectroscopy.

Electron exchange reactions between polyvalent elements in soda-lime-silica and sodium borate glasses
Creators: name: Müller-Simon, Hayo

Subjects: subject: 660

description: In oxidic glasses the redox State of polyvalent elements is determined by the oxygen partial pressure with which the melt is in equilibrium. However, if a second polyvalent element is introduced the redox ratios at a given oxygen pardal pressure change for both elements. This interaction is interpreted in terms of electron exchange reactions during cooling. The direcdon of the electron exchange and the amount of exchanged electrons are calculated from the Standard reaction enthalpy and Standard reaction entropy of the involved polyvalent elements. Oxygen balance calculations are carried out based on literature data available for iron/chromium and iron/manganese interaction in soda-lime-silic a glasses and cerium/manganese interaction in sodium borate glasses. The iron/ chromium and iron/manganese interaction fmishes already at high temperatures. In that case the amount of exchanged electrons can be calculated from stoichiometric considerations. The cerium/manganese couple shows a typical freezing-in behavior in sodium borate glass during cooling. The freezing-in temperature can be associated with the distance of the interacting ions.

Subjects: subject: 660

description: Α general introduction describes intentional and unintentional anisotropic phenomena resulting from chemical and thermal inhomogeneities (internal stresses) as well as anisotropies induced by external elastic stresses and strains in homogeneous glasses for special opdcal purposes. Further the paper will point out the possibilities and various phenomena of producing defmed anisotropies by means of flow stresses and strain rates in glass mehs which may be frozen-in by cooling under load. It will be distinguished between Single - and double-phase glass melts and glasses which show very different kinds and effects of anisotropies. In particular, optical anisotropies (birefringence, specific birefringence) and structural-mechanical anisotropies (densities, shrinkages and expansions during annealing) of single-phase glasses and glass melts will be investigated under defined flow condidons (in-situ measurements directly in glass melts by the classical flow birefringence) and geometries (e.g. cylindric bulk glass samples, glass fibres, glass rods). In double-phase glass Systems the following anisotropic properties will be treated: the form birefringence and the distribution birefringence of decomposed glasses, the orientation of melts with suspended anisometric crystals and birefringence effects of chemically leached microporous glasses. Finally, a new phenomenon will be reported where the frozen-in birefringence of a glass shows an other sign after deformation above Tg than the stress optical constant of the same glass at room temperature before this treatment above Tg.

description: We report the discovery of 1.97 ms period gamma-ray pulsations from the 75 minute orbital-period binary pulsar now named PSR J1653-0158. The associated Fermi Large Area Telescope gamma-ray source 4FGL J1653.6-0158 has long been expected to harbor a binary millisecond pulsar. Despite the pulsar-like gamma-ray spectrum and candidate optical/X-ray associations -- whose periodic brightness modulations suggested an orbit -- no radio pulsations had been found in many searches. The pulsar was discovered by directly searching the gamma-ray data using the GPU-accelerated Einstein@Home distributed volunteer computing system. The multi-dimensional parameter space was bounded by positional and orbital constraints obtained from the optical counterpart. More sensitive analyses of archival and new radio data using knowledge of the pulsar timing solution yield very stringent upper limits on radio emission. Any radio emission is thus either exceptionally weak, or eclipsed for a large fraction of the time. The pulsar has one of the three lowest inferred surface magnetic-field strengths of any known pulsar with $B_{\rm surf} \approx 4 \times 10^{7}\,$G. The resulting mass function, combined with models of the companion star's optical light curve and spectra, suggests a pulsar mass $\gtrsim 2\,M_{\odot}$. The companion is light-weight with mass $\sim 0.01\,M_{\odot}$, and the orbital period is the shortest known for any rotation-powered binary pulsar. This discovery demonstrates the Fermi Large Area Telescope's potential to discover extreme pulsars that would otherwise remain undetected.

description: We investigate the Einstein-Maxwell-scalar theory with a quasi-topological term. Considering exponential couplings to Maxwell term, quasi-topological term, and both terms, we obtain three sets of infinite scalarized charged black holes by taking into account tachyonic instability of dyonic Reissner-Nordström black hole. Each set of infinite scalarized charged black holes is classified by the number of $n=0,1,2,\cdots$, where $n=0$ is called the fundamental black hole and $n=1,2,\cdots$ denote the $n$-excited black holes. All $n=0$ black holes are stable against the radial perturbation, while all $n=1,2$ black holes are unstable.

description: Α hybridized fabrication process for single-mode optical fibers has been studied. The process consists of direct overcladding a VAD derived core rod with a porous body made from commercial silica powder by means of the cold isostatic pressing technique. By using a mixture of main silica powder with an average particle diameter of 10 µm and 1 w t% of fine silica powder with an average particle diameter of 0.04 µm and a core rod having a core/cladding diameter ratio of 1/2.4 as starting materials, large preforms for 300 km fibers were fabricated, which were drawn into fibers with attenuation losses of 0.350 dB/km at 1.31 µm and 0.232 dB/km at 1.55 µm. In the process, a special rubber mold with a structure in which both ends of the core rod are pressed by hydrostatic pressure makes the fabrication of large hybridized soot preforms possible, plastic deformation of the porous body during degreasing being remarkably reduced by using a suitable content of glycerol.

description: We revisit the problem of the gauge invariance in the Coleman-Weinberg model in which a $U(1)$ gauge symmetry is driven spontaneously broken by radiative corrections. It was noticed in previous work that masses in this model are not gauge invariant at one-loop order. In our analysis, we use the dressed propagators of scalars which include a resummation of the one-loop self-energy correction to the tree-level propagator. We calculate the one-loop self-energy correction to the vector meson using these dressed propagators. We find that the pole mass of the vector meson calculated using the dressed propagator is gauge invariant at the vacuum determined using the effective potential calculated with a resummation of daisy diagrams.

Subjects: subject: Transportation Engineering

description: The failure of metal bridges, subject to in-service fracture problems mainly caused by fatigue, may be prevented or minimized by performance of periodic nondestructive testing. Attendant factors that justify funding for such inspections include the potential for bridge failure, the consequences of bridge collapse, risk analyses, and inspection strategies. Factors that affect structural integrity include structural design, construction quality, and service loadings.  Details of a computer/strain-gage system capable of obtaining strain-gage data from critical structural elements are described. Data are processed to determine the stress-range distribution, number of stress cycles, resolved mean stress range, need for structural inspection, critical crack size, suitability of the inspection method, and required inspection interval.  Factors relating nondestructive test methods to periodic inspections are presented. The application of a functional acoustic-emission system suitable for bridge nondestructive inspection of bridges are described. Optimum test methods for conventional and cable bridges are presented.

description: Die Umweltrelevanz von deponierten Bildröhrengläsern wird an Hand von Elutionsversuchen dargelegt. Die Ergebnisse dieser Elutionsversuche, die nach einer DIN-Methode durchgeführt wurden, erwiesen sich als nicht reproduzierbar und führten teilweise zu widersprüchlichen Aussagen hinsichtlich der Einstufung von Bildröhrenglas zu den gesetzlich vorgeschriebenen Deponieklassen. Als Ursache wurden die in der DIN 38414 unzureichend definierten Versuchsparameter bei der Herstellung der Elutionslösungen identifiziert. Weiterhin sind Mehrfachbestimmungen für eine eindeutige Aussage unerläßlich. Die Anwendung einer definierten, von der Länderarbeitsgemeinschaft Abfall empfohlenen Elutionsmethode führt zu Elutionswerten, die eine Deponierung auf Inertstoffdeponien nicht zulassen. Solange keine andere Verwertungsmöglichkeit für Bildröhrenglas existiert und eine Rückführung in die Schmelze aus Gründen der Sortenreinheit nicht möglich ist, könnte das Bildröhrenglas vorteilhaft als Bergwerkversatz weiterverwendet werden. Hierbei muß gewährleistet sein, daß die Lagerstätte von Feuchtigkeit absolut freibleibt.

description: Directly imaged planets are self-luminous companions of pre-main sequence and young main sequence stars. They reside in wider orbits ($\sim10\mathrm{s}-1000\mathrm{s}$~AU) and generally are more massive compared to the close-in ($\lesssim 10$~AU) planets. Determining the host star properties of these outstretched planetary systems is important to understand and discern various planet formation and evolution scenarios. We present the stellar parameters and metallicity ([Fe/H]) for a subsample of 18 stars known to host planets discovered by the direct imaging technique. We retrieved the high-resolution spectra for these stars from public archives and used the synthetic spectral fitting technique and Bayesian analysis to determine the stellar properties in a uniform and consistent way. For eight sources, the metallicities are reported for the first time, while the results are consistent with the previous estimates for the other sources. Our analysis shows that metallicities of stars hosting directly imaged planets are close to solar with a mean [Fe/H] = $-0.04\pm0.27$~dex. The large scatter in metallicity suggests that a metal-rich environment may not be necessary to form massive planets at large orbital distances. We also find that the planet mass-host star metallicity relation for the directly imaged massive planets in wide-orbits is very similar to that found for the well studied population of short period ($\lesssim 1$~yr) super-Jupiters and brown-dwarfs around main-sequence stars.

Supporting user interaction for the exploratory mining of constrained frequent sets
Creators: name: Mah, Teresa
Publisher: name: University of British Columbia
Year: 2009

description: Data mining is known to some as "knowledge discovery from large databases". It is the technology of taking large quantities of data, and searching through the data looking for previously unknown patterns of information. One can see how this can be useful to entrepreneurs and researchers of all kinds. Retailers can apply data mining to find customer shopping patterns. On a grander scale, meteorologists can use the technology to identify telltale signs of extreme weather conditions, such as tornadoes or hurricanes. Unfortunately, albeit so useful, data mining has not yet broken out of its shell. There are two main reasons for this. The first reason is that the mining process is still slow, even with all the research done to optimize the algorithms. The second reason is that there has not been much work done on improving the user interaction aspect of the technology. Most of the systems created so far have resembled a black box. Input is entered in at one end of the black box, and output is received at the other end. There is no concept of human-centred exploration or control of the process, and no mechanism to specify focus in the database. The work described here provides a glimpse of a new exploratory mining framework that encourages exploration and control. In addition, this new framework is incorporated into the first fully functional prototype capable of constrained frequent set mining. A user of the prototype can specify focus by providing constraints on data to be mined, and can view frequent sets satisfying these constraints before relationships are found. The prototype also allows users to sort or format frequent set output, and to choose only interesting sets to find relationships on. Furthermore, frequent sets in our system can be mined between sets with different or similar domains, and users can choose other notions of relationship besides confidence. Combining this new exploratory mining paradigm with the faster, more efficient C A P algorithm, we have what we believe is the first in a new generation of fast and human-centred data mining systems.
Development and validation of a product creativity evaluation framework for the assessment of functional consumer products
Creators: name: Hazeri, Kamyar
Publisher: name: Imperial College London
Year: 2019

description: A reliable method for creativity assessment of functional consumer products has been developed. In literature, creativity is explored in four main aspects of person, process, press, and product known as 4P’s of creativity. In this research, the product creativity measurement is studied aiming at assisting designers to better understand creativity and to be able to implement it in the design process. The research begins with defining the role of creativity in engineering design and continues with reviewing existing approaches for measuring product creativity in three main categories. In this research, a goal is to investigate the ability of the CAT for the assessment of consumer products produced under non-experimental conditions. The CAT was used together with domain experts to assess three categories of consumer products for creativity (home-accessories, electric-vehicles, and smoke-alarms). The results of inter-judge reliabilities indicated that CAT can reliably evaluate these products, although a larger number of raters (10 to 15) compared to those in artistic domains is recommended. Factor analysis revealed that for products with complex structures (electric-vehicles), experts are unable to distinguish the border between creativity and other influential factors such as product’s technical performance and or aesthetic appeal. As a result, the assessment of complex engineering products should be performed with caution. A theoretical framework to enable researchers to develop their own criterion-based instrument based on the product’s functionality is presented. The framework comprises 65 indicators in nine broad categories. A case study using 5 lounge-chairs and 288 university students was conducted to test the applicability and validity of the framework. A new internally consistent and factorially valid model was achieved. Overall, this project contributed to the field by extending the usage of CAT into functional products and by proposing a new framework to evaluate creativity. Accordingly, researchers/designers can get insights and enhance product creativity.

description: Various silica glasses were engraved deliberately by excimer laser radiation using wavelengths of 308 and 248 nm. The ablation of different samples was investigated by systematic Variation of the processing parameters. The ablation rates were determined using profilometry and gravimetric measurements by evaluating the processing quaUty and the morphology of the processed surfaces was considered. The phenomenon of ablation is explained as a non-linear interaction of the laser beam and the glass. The experimental results show that the ablation behaviour of silica glass depends on the wavelength and the intensity of the laser radiation, on the surface quahty and the degree of purity of the glass. Although high ablation rates were obtained, the suitability of excimer lasers for micromachining is restricted due to the rough surface morphology and poorly defmed edges.

description: Quantum decoherence is the major obstacle in using the potential of engineered quantum dynamics to revolutionize high-precision measurements, sensitive detection, or information processing. Here we experimentally demonstrate that quantum state of a system can be recovered after the state is destroyed by uncontrollable natural decoherence. Physical system is a cluster of seven dipolar-coupled nuclear spins of single-labeled 13C-benzene in liquid crystal. 13C spin plays a role of a device for measuring protons' "cat" state, a superposition of states with six spins up (alive) and six spins down (dead). Information about the state, stored in the 13C spin, is used to bring the protons' subsystem into the alive state, while the excess entropy produced by decoherence is transferred to the "measuring device", the 13C spin.

description: The data on the proton form factors in the time-like region from the BaBar, BESIII and CMD-3 Collaborations are examined to have coherent pieces of information on the proton structure. Oscillations in the annihilation cross section, previously observed, are determined with better precision. The moduli of the individual form factors, determined for the first time, their ratio and the angular asymmetry of the annihilation reaction $e^+e^-\to\bar p p$ are discussed. Fiits of the available data on the cross section, the effective form factor, and the form factor ratio, allow to propose a description of the electric and magnetic time-like form factors from the threshold up to the highest momenta.

description: Entanglement can be generated by two electrons in a spin-zero state on a semiconducting single-walled carbon nanotube. The two electrons, one weakly bound in a shallow well in the conduction band, and the other injected into the conduction band, are coupled by the Coulomb interaction. Both transmission and entanglement are dependent on the well characteristics, which can be controlled by a local gate, and on the kinetic energy of the injected electron. Regimes with different degrees of electron correlation exhibit full or partial entanglement. In the latter case, the maximum entanglement can be estimated as a function of width and separation of a pair of singlet-triplet resonances.

description: The article presents a theoretical generalization and a new solution to the scientific problem – increasing the yield and oil content in winter rapeseed, which is to improve the elements of cultivation technology and the use of hybrids of different maturity groups. The obtained results and developed recommendations are a set of approaches to the possibility of increasing the productivity of winter rapeseed hybrids. For the first time in the conditions of the Right-Bank Forest-Steppe of Ukraine the peculiarities of growth and development of winter rapeseed hybrids Exotic, Excel, Exagon and their seed productivity at different sowing dates and norms of mineral fertilizers have been established; their influence on the formation of elements of productivity is determined, economic and energy efficiency of winter rapeseed growing is carried out. Some elements of the technology of growing rapeseed hybrids have been improved, which has provided opportunities to increase the yield and improve the seed quality of the studied hybrids in the conditions of the Right-Bank Forest-Steppe of Ukraine. Further developments are the scientific provisions to increase the productivity of winter oilseed rape, based on the evaluation of new hybrids of different maturity groups and the integrated application of elements of technology. The best conditions for the synthesis of organic matter, which forms the productivity of plants, were created under the influence of the fertilizer rate N240P120K240 and the sowing period inherent in the maturity group of the hybrid. The highest rate of net photosynthesis productivity of 15.41 g/m2 per day was obtained by the hybrid Excel during the first sowing period when applying N240P120K240. On average over the years of research, the maximum yield was achieved by medium-ripe hybrid Exotic for the first sowing period with the introduction of the maximum fertilizer N240P120K240 – 4.10 t/ha. The best values of the acid number were in the hybrid Exagon for the first sowing period – 1.38-1.10 mg KOH/g. The maximum value of protein content in hybrids Exotic and Excel was observed during the second sowing period on August 21 and increased with increasing fertilizer rate from 19.07 to 22.57% and from 19.57 to 22.65%. The maximum value of oil content (total yield) was obtained in the variant with the introduction of N240P120K240 in the hybrid Exotic 1.85 t/ha during the first sowing period. According to the results of the study, the technology of growing winter rape was developed and recommended for production, which will ensure the formation of crop productivity at the level of 3.8-4.10 t/ha with high seed quality.

description: The article examines the techniques of ploughing as a component of differentiated tillage, which remains competitive in comparison with the method of sowing in mulch. The essence of the classical tillage method that guarantees obtaining a stable harvest is outlined. The advantages and problem aspects of ploughing as the main method of classical tillage technology are analyzed. It has been proved that in order to restore the structure of the top layer of soil, ploughing is mandatory, though not annually, but once every few years. It is noted that ploughing best covers crop residues and organic solid fertilizers and enables to successfully control weeds that are resistant to modern herbicides. Emphasis is made on applying cultural ploughing, which ensures higher soil fertility. The issue of control of soil compaction that arises under mechanical tillage methods is clarified. It is established that economic preconditions for crop losses affect the reasons why farmers neglect the methods of preventing soil compaction.

description: Α comparative study of electrochemical oxygen sensors for glass melts employing zirconia solid electrolytes developed by Schott Glaswerke and by the HVG is reported. The sensors applied in a feeder Channel of a melting tank producing green glass yielded slightly different but reproducible results despite different constructions. The zirconia reference electrodes achieved more than one year active lifetime at 1200°C. Their potentials directly compared over extended periods agreed within less than 3 mV. The potential differences of the platinum measuring electrodes were traced to temperature gradients. Newly installed platinum electrodes show "induction periods" caused by convectional and diffusional equilibration of adhering surface with bulk melt. Unexpected sudden oxygen inhomogeneities of the melt were detected and explained.

description: An accurate investigation of the emissivity of uncoated flat glass (necessary to calculate the solar factor and the U value of glazing according to standardized procedures) was performed in agreement with Groupement Europeen des Producteurs de Verre Fiat, in support of CEN and ISO standardization activities. The total angular emissivity of a range of uncoated float glass samples was determined between 10 and 80 °C with an uncertainty of 0.5%. Both the normal and the hemispherical emissivity were nearly identical for all the samples investigated. No significant differences between the top and the bottom side were observed. Measurements were also extended to borosilicate glass and glass-ceramic plates used for fire-resistant glazing, determining their thermal conductivity and angular emissivity behaviour. In order to obtain addidonal information, also the spectral reflectance curves at near normal incidence between 2000 and 200 c m ⁻¹ were obtained using a spectroradiometer. The fact that almost identical curves were obtained for a wide range of float glasses (both sides) as well as for the fire-resistant materials confirms the correctness of the close emissivity values found. On the basis of the resuhs obtained, a Standard value of εn = 0.900 and a εh/εn ratio = 0.936 is suggested for both float glass and for the two other materials.

description: We study a model of active particles that perform a simple random walk and on top of that have a preferred direction determined by an internal state which is modelled by a stationary Markov process. First we calculate the limiting diffusion coefficient. Then we show that the `active part' of the diffusion coefficient is in some sense maximal for reversible state processes. Further, we obtain a large deviations principle for the active particle in terms of the large deviations rate function of the empirical process corresponding to the state process. Again we show that the rate function and free energy function are (pointwise) optimal for reversible state processes. Finally, we show that in the case with two states, the Fourier-Laplace transform of the distribution, the moment generating function and the free energy function can be computed explicitly. Along the way we provide several examples.

"Slow" Radio Bursts from Galactic Magnetars?

description: Recently, one fast radio burst, FRB 200428, was detected from the Galactic magnetar SGR J1935+2154 during one X-ray burst. This suggests that magnetars can make FRBs. On the other hand, the majority of X-ray bursts from SGR J1935+2154 are not associated with FRBs. One possible reason for such rarity of FRB-SGR-burst associations is that the FRB emission is much more narrowly beamed than the SGR burst emission. If such an interpretation is correct, one would expect to detect radio bursts with viewing angles somewhat outside the narrow emission beam. These "slow" radio bursts (SRBs) would have broader widths and lower flux densities due to the smaller Doppler factor involved. We derive two "closure relations" to judge whether a long, less luminous radio burst could be an SRB. The 2.2-s, 308 Jy ms, 111 MHz radio burst detected from SGR J1935+2154 by the BSA LPI radio telescope may be such an SRB. The 2-ms, 60 mJy ms faint burst detected by FAST from the same source could be also an SRB if the corresponding FRB has a narrow spectrum. If the FRB beam is narrow, there should be many more SRBs than FRBs from Galactic magnetars. The lack of detection of abundant SRBs from magnetars would disfavor the hypothesis that all SGR bursts are associated with narrow-beam FRBs.

description: Baryon chiral perturbation theory with explicit $Δ(1232)$ degrees of freedom is considered. Using the extended on-mass-shell renormalization scheme, a manifestly Lorentz-invariant effective field theory with a systematic power counting is obtained. As applications we discuss the mass of the nucleon, the pion-nucleon sigma term, and the pole of the $Δ$ propagator.

description: Residual stress measurements in many bottles, tumblers and in other axisymmetric glass articles by using integrated photoelasticity have shown that the residual stress distribution often deviates from the axially Symmetrie one. Α method is developed which enables determination of nonaxisymmetric residual stress distribution. Α computer-controlled polariscope has been developed for automatic measurements. Several examples of residual stress distributions, which deviate strongly from the axisymmetric one, are given. It is shown that deviadons from axial symmetry lead to less favorable distribution of the residual Stresses; e.g., they may lead to tensile residual Stresses on the external surface of bottles.
Vector mesons on the wall

description: A domain-wall configuration of the $η'$ meson bounded by a string (called a pancake or a Hall droplet) is recently proposed to describe the baryons with spin $N_c/2$. In order to understand its baryon number as well as the flavor quantum number, we argue that the vector mesons (the $ρ$ and $ω$ mesons) should play an essential role for the consistency of the whole picture. We determine the effective theory of large-$N_c$ QCD with $N_f$ massless fermions by taking into account a mixed anomaly involving the $θ$-periodicity and the global symmetry. The anomaly matching requires the presence of a dynamical domain wall on which a $U(N_f)_{-N_c}$ Chern-Simons theory is supported. We consider the boundary conditions that should be imposed on the edge of the domain wall, and conclude that there should be a boundary term that couples the $U(N_f)_{-N_c}$ gauge field to the vector mesons. We discuss the impact on physics of the chiral phase transition and the relation to the "duality" of QCD.

description: We report on the first detailed measurements of electron backscattering from plastic scintillator targets, extending our previous work on beryllium and silicon targets. The scintillator experiment posed several additional experimental challenges associated with charging of the scintillator target, and those challenges are addressed in detail. In addition, we quantitatively compare the energy and angular distributions of this data, and our previous data, with electron transport simulations based on the Geant4 and Penelope Monte Carlo simulation codes. The Penelope simulation is found globally to give a superior description of the data. Such information is crucial for a broad array of weak-interaction physics experiments, where electron backscattering can give rise to the dominant detector-related systematic uncertainty.

Early immersion effects on cognition: Evidence from a US charter school teaching L2 Greek

description: The present study investigates the degree to which length of L2 experience and intensity of L2 exposure may affect young learners’ executive function system at the very early stages of foreign language instruction. More specifically, we tested the effect of increased exposure to L2 Greek on young learners’ updating, inhibition and executive attention. The study took place in a US charter school which offers foreign language instruction with Greek as L2 in two different types of programs: FLES (Foreign Languages in Elementary Schools) and Immersion. Fifty-six 6- and 7-year-old students were tested: twenty-six students in grade 1 (thirteen students/group) and thirty students in grade 2 (fifteen students/group). Based on our results, both groups displayed cognitive gains of a different degree, with the immersion groups displaying more prominent cognitive gains than the FLES groups. The study contributes to research in the cognitive impact of intensive foreign language education on young learners by examining a pair of languages (L1 English, L2 Greek) that, to our knowledge at least, has never before been researched in the US educational context.

Theory and molecular modelling of gas adsorption in nanopores

Publisher: name: Imperial College London

description: The accurate modelling of confined fluids has a significant impact in the design of new processes and technologies. This work aims to provide new tools for the description of the adsorption of fluids in nanoporous solid materials. In terms of theoretical modelling, an extension of the statistical associating fluid theory (in its SAFT-VR-Mie version) equation of state is developed to take into account the effect of confinement of fluids into cylindrical pores. The capability of the proposed model is showcased by fitting adsorption isotherms of pure fluids such as; methane and n−nonane on activated carbons; ethane, n−hexane and benzene on MCM- 41, and methane and carbon dioxide on carbon surrogate models of shale rocks; providing for an accurate correlation of the data with parameters that are temperature- independent and robust. Further insight is obtained through molecular simulation of model systems, where the onus is on studying the effect of molecular and pore morphologies on adsorption isotherms and diffusion. Three distinct geometries of fluids are considered; trimers forming a flexible chain, a rigid linear chain, and a ring-like structure (triangular configuration). Moreover, cylindrical pores with three different values of pore diameters and three levels of solid-fluid interaction strength are employed. It is seen that both the molecular shape and the surface attractions play a decisive role in the shape of the adsorption isotherm. In general, the ring molecules show a larger adsorption, while the fully flexible model shows the smallest adsorption. High adsorption and diffusion are observed for the linear stiff molecules in ultra-confinement, due to a phase transition of the adsorbed fluid into a nematic liquid crystal. A further study is presented about the effect that pore geometry has on adsorption isotherms, where the chosen pores have cross sections representing: triangle, square, pentagon, hexagon, octagon, decagon and circle configurations (all of them with the same cross-sectional area). For high fluid-solid energy interactions and, in particular, for pores of dimensions commensurate with the molecular size, the presence of vertices in the pores and the intensity of the energy on these areas significantly enhance the adsorption of fluids.

description: Earth system models are composed of coupled components that separately model systems such as the global atmosphere, ocean, and land surface. While these components are well developed, coupling them in a single system can be a significant challenge. Computational efficiency, accuracy, and stability are principal concerns. In this study, we focus on these issues. In particular, implicit-explicit (IMEX) tight and loose coupling strategies are explored for handling different time scales. For a simplified model for the air-sea interaction problem, we consider coupled compressible Navier-Stokes equations with an interface condition. Under the rigid-lid assumption, horizontal momentum and heat flux are exchanged through the interface. Several numerical experiments are presented to demonstrate the stability of the coupling schemes. We show both numerically and theoretically that our IMEX coupling methods are mass conservative for a coupled compressible Navier-Stokes system with the rigid-lid condition.

description: This paper presents data on the beliefs, attitudes, and reported practices of state school teachers concerning the education of immigrant/refugee children. Teachers’ beliefs are generally considered to exert an important influence on their professional practices, while relevant findings in recent research appear contradictory. The 56 informants participated in online seminars organized by the information service “Me 2 Glosses” and the Prefectural Directorate of Education of Epirus in 2020–2021. Upon completion of the seminars, an online questionnaire was administered which included questions on the use and maintenance of heritage languages, bilingual profile, academic differences between monolingual and bilingual students and teaching practices supporting bilingualism. Teachers’ answers indicate that their efforts to support immigrant/refugee students focus on the development of their linguistic skills in Greek. However, the results also indicate a lack of awareness regarding the importance of acknowledging those students’ heritage language and culture; such practices would be clear indicators of teachers’ accepting their students’ diversity.
