description: Post-transplant diabetes mellitus (PTDM) after kidney transplantation induced by tacrolimus is an important issue. Fast tacrolimus metabolism, which can be estimated by concentration-to-dose (C/D) ratio, is associated with increased nephrotoxicity and unfavorable outcomes after kidney transplantation. Herein, we elucidate whether fast tacrolimus metabolism also increases the risk for PTDM. Data from 596 non-diabetic patients treated with tacrolimus-based immunosuppression at the time of kidney transplantation between 2007 and 2015 were retrospectively analyzed. The median follow-up time after kidney transplantation was 4.7 years (IQR 4.2 years). Our analysis was complemented by experimental modeling of fast and slow tacrolimus metabolism kinetics in cultured insulin-producing pancreatic cells (INS-1 cells). During the follow-up period, 117 (19.6%) patients developed PTDM. Of all patients, 210 (35.2%) were classified as fast metabolizers (C/D ratio < 1.05 ng/mL × 1/mg). Fast tacrolimus metabolizers did not have a higher incidence of PTDM than slow tacrolimus metabolizers (p = 0.496). Consistent with this, insulin secretion and the viability of tacrolimus-treated INS-1 cells exposed to 12 h of tacrolimus concentrations analogous to the serum profiles of fast or slow tacrolimus metabolizers or to continuous exposure did not differ (p = 0.286). In conclusion, fast tacrolimus metabolism is not associated with increased incidence of PTDM after kidney transplantation, either in vitro or in vivo. A short period of incubation of INS-1 cells with tacrolimus using different concentration profiles led to comparable effects on cell viability and insulin secretion in vitro. Consistent with this, in our patient, collective fast Tac metabolizers did not show a higher PTDM incidence compared to slow metabolizers.

description: We report on high-field angle-dependent magneto-transport measurements on epitaxial thin films of Bi2Se3, a three-dimensional topological insulator. At low temperature, we observe quantum oscillations that demonstrate the simultaneous presence of bulk and surface carriers. The magneto- resistance of Bi2Se3 is found to be highly anisotropic. In the presence of a parallel electric and magnetic field, we observe a strong negative longitudinal magneto-resistance that has been consid- ered as a smoking-gun for the presence of chiral fermions in a certain class of semi-metals due to the so-called axial anomaly. Its observation in a three-dimensional topological insulator implies that the axial anomaly may be in fact a far more generic phenomenon than originally thought.

Subjects: Education

description: This paper discusses the importance of defnitions in the context of academic discussion, highlights the inconsistent terminology used to describe e-learning, and examines a range of diferent defnitions of e-learning used by academic authors since 2011. Following an outline of the methodology, the paper identifes 15 unique defnitions of e-learning in peer-reviewed papers published between January 2011 and December 2022. The 15 defnitions are analysed for signifcant properties, and these properties are reviewed to assess whether they are essential components of e-learning. The paper then proposes a functional defnition of e-learning, including all essential elements of e-learning and eliminating elements that may be present in some, but not all, instances of e-learning.

description: We investigate the scattering and absorption properties of anisotropic metal-dielectric core-shell nanoparticles. It is revealed that the radially anisotropic dielectric layer can accelerate the evanescent decay of the localized resonant surface modes, leading to Q-factor and absorption rate enhancement. Moreover, the absorption cross section can be maximized to reach the single resonance absorption limit. We further show that such artificial anisotropic cladding materials can be realized by isotropic layered structures, which may inspire many applications based on scattering and absorption of plasmonic nanoparticles.

How to Use Social Media to Better Engage People Affected by Crises

Publisher: name: Zenodo

description: In the past few years, the role of social media and digital technologies in times of disasters and crises has grown exponentially. During disasters like the 2011 Tohoku earthquake and tsunami, and the 2015 Nepal earthquake, for instance, Facebook and Twitter were crucial components of the humanitarian response, allowing mostly local, but also international actors involved in relief efforts, to disseminate lifesaving messages. They also offered affected communities a channel to seek help, reconnect with their families and provide feedback on the assistance received so that programmes could be adapted, when possible. Existing studies show that digital communications channels can be critical before, during and after natural disasters, crises and armed conflicts, to save lives and reduce suffering (e.g. by disseminating of early warning messages and safety tips, helping people to reconnect with their loved ones, directing affected people to humanitarian services...). However, the use of social media by humanitarian organizations to engage and communicate with (not about) affected people is, to date, still vastly untapped, and largely under researched and documented in terms of the provision of practical guidance, both thematically and technically, good practices and lessons learned.This brief guide, initiated by the International Committee for the Red Cross (ICRC) and the International Federation of Red Cross and Red Crescent Societies (IFRC), and developed with support from the Office for the Coordination of Humanitarian Affairs (OCHA), is a living document that aims to address this.

description: Climate change has led to urgent calls for environmental action and justice, which is likely to include increased urban vegetation. The benefits of this planting could go beyond ecological and climate benefits to contribute to decolonisation and environmental and spatial justice and build on the well-documented links between ecological and human wellbeing. In Aotearoa New Zealand, past and ongoing injustices resulting from colonisation have disconnected Māori (the Indigenous people) from their land. Māori see themselves reflected in the landscape and te taiao (the natural world). The process of colonisation has mostly erased natural heritage, intrinsic to Māori identity, from urban areas. Many plants in urban areas represent colonial identity rather than this natural heritage, and many of the native plants that have been planted originate from other parts of the country. Through reviewing the literature, this article argues for research that determines the benefits of urban planting design prioritising plants that naturally occurred in the past, termed here ‘plants of place’, in public places. In settler colonial countries, where it is an accepted practice to acknowledge built and predominantly colonial heritage, making pre-colonial natural heritage visible can have many co-benefits. It has the potential to contribute to climate change mitigation and adaptation, decolonisation efforts, spatial justice and environmental justice. Celebrating natural heritage and planting ‘plants of place’ can contribute in some part to righting past injustices and preparing for a changing future.
title: The Transplantation of Theatre-in-Education from Britain to Taiwan
Creators: name: Tsai, Chi-chang
Publisher: name: Goldsmiths, University of London
Year: 2004

description: The British-born Theatre-in-Education (TIE) is now an international phenomenon. Theatre and education practitioners worldwide have come to recognise TIE as an important resource for the reinforcement of institutional or orthodox education. In Taiwan, by way of cultural exchanges and in accordance with the practice of the well meant, but not so well planned education reforms, TIE has also been gradually adopted by drama specialists and professional theatre groups over the last decade to provide young students with alternative experiences of active learning. During this process of transplantation, the representation of TIE has become an issue that demands careful deliberation in the island. This dissertation surveys the development of Theatre-in-Education in Taiwan from a personal perspective, as well as demonstrating the interdisciplinary relationship between TIE and regional/community theatre through a case study on the encounter of the Greenwich and Lewisham Young People's Theatre (GYPT) and the Tainan Jen Theatre Troupe. By making use of first-hand experience of TIE transplantation (from Britain to Taiwan) and of interviews with TIE practitioners, the author intends to contextualise the Taiwanese TIE movement by relating it to an international trend of audience-oriented theatre. Within this framework, the author argues that the localisation of British TIE in Taiwan is best embodied, and therefore can be expected to find strength in the association of TIE and those Taiwanese theatre groups of or with a community-friendly nature; in addition, the continuing social, cultural and educational reforms will create a better environment for the growth of Theatre-in-Education in the island.

description: We analyze 15,000 spectra of 29 stellar-mass black hole candidates collected over the 16-year mission lifetime of RXTE using a simple phenomenological model. As these black holes vary widely in luminosity and progress through a sequence of spectral states, which we broadly refer to as hard and soft, we focus on two spectral components: The Compton power law and the reflection spectrum it generates by illuminating the accretion disk. Our proxy for the strength of reflection is the equivalent width of the Fe-K line as measured with respect to the power law. A key distinction of our work is that for all states we estimate the continuum under the line by excluding the thermal disk component and using only the component that is responsible for fluorescing the Fe-K line, namely the Compton power law. We find that reflection is several times more pronounced (~3) in soft compared to hard spectral states. This is most readily caused by the dilution of the Fe line amplitude from Compton scattering in the corona, which has a higher optical depth in hard states. Alternatively, this could be explained by a more compact corona in soft (compared to hard) states, which would result in a higher reflection fraction.

description: In Aotearoa New Zealand, the history of migration and increased globalisation is reshaping social and cultural frameworks, presenting both challenges and opportunities for the creation and utilisation of public open spaces. This study investigates how these pressures influence Indigenous groups, specifically Māori, as they navigate an interplay of cultural beliefs and interactions with a non-Māori world. Concurrently, the progressively diverse nature of migrants, who consider themselves part of both their country of origin and New Zealand society, adds further complexity. This research aims to explore the potential of public open spaces to encourage a sense of community among the major ethnic groups in New Zealand, including New Zealand Europeans, Māori, Chinese, and Pasifika. Drawing on the Sense of Community theory proposed by McMillan and Chavis, this study investigates the impact of community participation in public open space planning on the sense of community among these groups. Through a quantitative online survey, the Sense of Community Index-2 was utilised for assessing the extent to which participatory planning nurtures a sense of community. The findings suggest that participatory planning offer valuable opportunities for integrating public perspectives, fostering sense of community, and creating inclusive spaces that celebrate cultural diversity in Aotearoa New Zealand.

description: The growing interest in Traditional Ecological Knowledge (TEK) and Indigenous worldviews has refocused attention on land and resource management systems as well as local knowledge of flora and fauna. As Western medicine often ignores the spiritual and mental intricacies of health, finding a balance between Western and Non-Western knowledge is vital to creating a culturally and ecologically responsive environment. This paper addresses the growing interest in TEK as a catalyst for urban landscape regeneration by incorporating the biophysical dimensions of place and environment. It explores the proposed design of a Māori Rongoā learning garden in a public space in the city of Wellington, the capital city of New Zealand. By identifying opportunities in designing plant collections and issues for plant harvesting, this paper aids the discourse on potential cultural collisions and strategies for both reconnecting with Indigenous people but also connecting non-Indigenous people to the natural surroundings.

description: Many-body localization (MBL) in a one-dimensional Fermi Hubbard model with random on-site interactions is studied. While for this model all single-particle states are trivially delocalized, it is shown that for sufficiently strong disordered interactions the model is many-body localized. It is therefore argued that MBL does not necessary rely on localization of the single-particle spectrum. This model provides a convenient platform to study pure MBL phenomenology, since Anderson localization in this model does not exist. By examining various forms of the interaction term a dramatic effect of symmetries on charge transport is demonstrated. A possible realization in a cold atom experiments is proposed.

Modeling Social Groups, Policies and Cognitive Behavior in COVID-19 Epidemic Phases. Basic Scenarios

description: The Covid-19 pandemic is distinct from Spanish flu of 1918 from many aspects among which the contrast between the overabundance of worldwide exchange of information (infomedia) and the actual scarce knowledge of the pathogen and the infection mechanism. Another important distinction is that the epidemics threaten society components, social groups, communities and jobs in very different ways and different death tolls. With this in mind, we start with simple models of pandemics and we drive the reader to more complex models that take into accounts social compartments and communities. The discrete-state models are built by adding elements, first in a mean-field approximation, then adding age classes and differential contact rates, and finally inserting the social group dimension. The novel element we insert is the effect of restrictions in contacts and travels, filtered by the risk perception, according with the growth of the number of infected or recovered people. Assimilating risk perception with cognitive behavior, we obtain several coarse-grain scenarios, that can be used for instance to calibrate the level of restrictions so not to exceed the capacity of the health system, and to speed the post-emergency recovery.

description: Numerical models and computer-aided modeling software are tools commonly used to assess the accessibility of an environment, based on static human body dimensions. In this paper, the limits of validity of these approaches are assessed by comparing the reach envelopes obtained by these methods to those obtained experimentally. First, the accessibility areas of forty adult subjects, which may correspond to the distance of reachability of products, were evaluated by performing an accessibility task comprising 168 reach points. Second, anthropometric characteristics of participants were recorded and used to perform the reach assessment by a numerical method, and then by a CAD-based analysis, where the reach was predicted using the software's maximum reach-envelope generation. In spite of the simple nature of the presented design problem (two-dimensional), the results show important differences between the three methods. The study of the number of reached points shows that the CAD-based assessment provides more accurate results than the numerical model. Nevertheless, the shapes envelopes comparison indicates that the maximum reach envelopes obtained with the CAD analysis are not always consistent with those obtained experimentally, closely linked to the hand location. Results indicate that the CAD model used to obtain maximum reaches gave predictions that underestimate the reach ability.

The calculation includes the connected diagrams and the leading, quark-line-disconnected diagrams. We incorporate algorithmic improvements developed in our previous work. The calculation was performed on the $48^3 \times 96$ ensemble generated with a physical-pion-mass and a 5.5 fm spatial extent by the RBC and UKQCD collaborations using the chiral, domain wall fermion (DWF) formulation. We find $a_μ^{\text{HLbL}} = 5.35 (1.35) \times 10^{- 10}$, where the error is statistical only. The finite-volume and finite lattice-spacing errors could be quite large and are the subject of on-going research. The omitted disconnected graphs, while expected to give a correction of order 10\%, also need to be computed.

description: Knowing the distribution of stellar rotational velocities is essential for the understanding stellar evolution. Because we measure the projected rotational speed vsini, we need to solve an ill-posed problem given by a Fredholm integral of the first kind to recover the true rotational velocity distribution. After discretization of the Fredholm integral, we apply the Tikhonov regularization method to obtain directly the probability distribution function for stellar rotational velocities. We propose a simple and straightforward procedure to determine the Tikhonov parameter. We applied Monte Carlo simulations to prove that Tikhonov method is a consistent estimator and asymptotically unbiased. This method is applied to a sample of cluster stars. We obtain confidences intervals using bootstrap method. Our results are in good agreement with the one obtained using the Lucy method, in recovering the probability density distribution of rotational velocities. Furthermore, Lucy estimation lies inside our confidence interval. Tikhonov regularization is a very robust method that deconvolve the rotational velocity probability density function from a sample of vsini data straightforward without needing any convergence criteria.

Here we propose a mixed dark energy domination which is constituted by tachyon, quintessence, and phantom scalar fields nonminimally coupled to gravity, in the absence of background dark matter and baryonic matter, in the framework of teleparallel gravity. We perform the phase-space analysis of the model by numerical methods and find the late-time accelerated attractor solutions implying the acceleration phase of universe.

description: In the last years, increasing efforts have been put into the development of effective stress tests to quantify the resilience of financial institutions. Here we propose a stress test methodology for central counterparties based on a network characterization of clearing members, whose links correspond to direct credits and debits. This network constitutes the ground for the propagation of financial distress: equity losses caused by an initial shock with both exogenous and endogenous components reverberate within the network and are amplified through credit and liquidity contagion channels. At the end of the dynamics, we determine the vulnerability of each clearing member, which represents its potential equity loss. We apply the proposed framework to the Fixed Income asset class of CC&G, the central counterparty operating in Italy whose main cleared securities are Italian Government Bonds. We consider two different scenarios: a distributed, plausible initial shock, as well as a shock corresponding to the cover 2 regulatory requirement (the simultaneous default of the two most exposed clearing members). Although the two situations lead to similar results after an unlimited reverberation of shocks on the network, the distress propagation is much more hasty in the latter case, with a large number of additional defaults triggered at early stages of the dynamics. Our results thus show that setting a default fund to cover insolvencies only on a cover 2 basis may not be adequate for taming systemic events, and only very conservative default funds, such as CC&G's one, can face total losses due to the shock propagation. Overall, our network-based stress test represents a refined tool for calibrating default fund amounts.

description: Nakuru’s strong commitment to sustainable urbanization, guided by the United Nations’ New Urban Agenda (NUA) and Sustainable Development Goal (SDG) 11, positions it at the forefront of urban development. In this context, questions arise regarding how Nakuru can domesticate NUA and SDG 11 for sustainable development and also become a more just place for its citizens. This paper introduces socially just urban mobility as a transformative force which can harness the values of sustainable urbanization by linking them to the Just City principles. Specifically, it shows how socially just public transport can optimize the city’s social and intangible values through fostering public participation, inclusivity, urban governance, and management. The paper highlights the Just City’s outstanding potential to domesticate NUA and SDG 11 for a just and sustainable Nakuru. It presents six policy recommendations with which the city can reimagine its urban mobility through socially just public transport into a more citizen-centered, democratic, and just space.

description: Gomes-Júnior et al. (2015) published 3613 positions for the 8 largest irregular satellites of Jupiter and 1787 positions for the largest irregular satellite of Saturn, Phoebe. These observations were made between 1995 and 2014 and have an estimated error of about 60 to 80 mas. Based on this set of positions, we derived new orbits for the eight largest irregular satellites of Jupiter: Himalia, Elara, Pasiphae, Carme, Lysithea, Sinope, Ananke and Leda. For Phoebe we updated the ephemeris from Desmars et al. (2013) using 75% more positions than the previous one. Due to their orbital characteristics, it is common belief that the irregular satellites were captured by the giant planets in the early Solar System, but there is no consensus for a single model explaining where they were formed. Size, shape, albedo and composition would help to trace back their true origin, but these physical parameters are yet poorly known for irregular satellites. The observation of stellar occultations would allow for the determination of such parameters. Indeed Jupiter will cross the galactic plane in 2019-2020 and Saturn in 2018, improving a lot the chances of observing such events in the near future. Using the derived ephemerides and the UCAC4 catalogue we managed to identify 5442 candidate stellar occultations between January 2016 and December 2020 for the 9 satellites studied here. We discussed how the successful observation of a stellar occultation by these objects is possible and present some potential occultations.

Formation and Fractionation of CO (carbon monoxide) in diffuse clouds observed at optical and radio wavelengths

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

description: We modelled \HH\ and CO formation incorporating the fractionation and selective photodissociation affecting CO when \AV\ $\la2$mag. UV absorption measurements typically have N(\cotw)/N(\coth) $\approx 65$ that are reproduced with the standard UV radiation and little density dependence at n(H) $\approx32-1024\pccc$: Densities n(H) $\la256\pccc$ avoid overproducing CO. Sightlines observed in mm-wave absorption and a few in UV show enhanced \coth\ by factors of 2-4 and are explained by higher n(H) $\ga256\pccc$ and/or weaker radiation. The most difficult observations to understand are UV absorptions having N(\cotw)/N(\coth) $>$100 and N(CO)$\ga10^{15}\pcc$. Plots of \WCO\ vs. N(CO) show that \WCO\ remains linearly proportional to N(CO) even at high opacity owing to sub-thermal excitation. \cotw\ and \coth\ have nearly the same curve of growth so their ratios of column density/integrated intensity are comparable even when different from the isotopic abundance ratio. For n(H)$\ga128\pccc$, plots of \WCO\ vs N(CH) are insensitive to n(H), and \WCO/N(CO)$\approx1\Kkms/(10^{15}~{\rm CO}\pcc)$: This compensates for small CO/\HH\ to make \WCO\ more readily detectable. Rapid increases of N(CO) with n(H), N(H) and N(\HH) often render the CO bright, ie a small CO-\HH\ conversion factor. For n(H) $\la64\pccc$ CO enters the regime of truly weak excitation where \WCO $\propto$n(H)N(CO). \WCO\ is a strong function of the average \HH\ fraction and models with \WCO=1\Kkms\ fall in the narrow range \mfH2\=0.65-0.8, or \mfH2\=0.4-0.5 at \WCO\=0.1\Kkms. The insensitivity of easily-detected CO emission to gas with small \mfH2\ implies that even deep CO surveys using broad beams may not discover substantially more emission.

description: We grew single crystals of U6Co by the self-flux method and measured the magnetic susceptibility, resistivity, and specific heat. The magnetic susceptibility shows very small anisotropy and weak temperature dependence, indicating small spin-susceptibility. Superconductivity was clearly observed in the resistivity, susceptibility, and specific heat at Tc~2.3K. The upper critical field was remarkably large, 7.9 and 6.6T for H || [001] and [110], respectively, in the tetragonal structure, indicating that the ellipsoidal Fermi surface is slightly suppressed along the [001] direction according to the effective mass model. The specific heat shows a large jump at Tc with Delta C/gamma Tc = 1.58, and the field dependence of the specific heat at low temperatures shows an almost linear increase. These experimental results are well explained by the BCS model in the dirty limit condition. U6Co is most likely a conventional s-wave superconductor with a full superconducting gap.

description: We propose a route toward realizing fractionalized topological phases of matter (i.e. with intrinsic topological order) by literally building on un-fractionalized phases. Our approach employs a Kondo lattice model in which a gapped electronic system of non-interacting fermions is coupled to non-interacting local moments via the exchange interaction. Using general entanglement-based arguments and explicit lattice models, we show that in this way gapped spin liquids can be induced in the spin system. We demonstrate the power of this topological bootstrap concept with two examples: (1) a chiral spin liquid induced by a Chern insulator and (2) a Z2 spin liquid induced by a superconductor. In particular, in the latter example, the toric code is realized as an exactly solvable example of topological bootstrap. Our approach can be generalized to all lattices, higher dimensions, and non-abelian topological orders.

description: Many processes within galaxy clusters, such as those believed to govern the onset of thermally unstable cooling and AGN feedback, are dependent upon local dynamical timescales. However, accurately mapping the mass distribution within individual clusters is challenging, particularly towards cluster centres where the total mass budget has substantial radially-dependent contributions from the stellar, gas, and dark matter components. In this paper we use a small sample of galaxy clusters with deep Chandra observations and good ancillary tracers of their gravitating mass at both large and small radii to develop a method for determining mass profiles that span a wide radial range and extend down into the central galaxy. We also consider potential observational pitfalls in understanding cooling in hot cluster atmospheres, and find tentative evidence for a relationship between the radial extent of cooling X-ray gas and nebular H-alpha emission in cool core clusters. Amongst this small sample we find no support for the existence of a central 'entropy floor', with the entropy profiles following a power-law profile down to our resolution limit.

description: Technical and vocational education and training (TVET) institutions and industries need more collaboration to provide relevant practical skills for industrialization. COVID-19 pandemic disrupted learning globally in all institutions since the year 2019, leading to a desire have alternative means of providing practical technical training to learners, including online learning. The research objectives for this study were to: determine the capacity of industry to provide technical training to trainees; probe trainees’ ability to use learning management systems that link TVET institutions to industry; and identify suitable assessment methods. This study investigated how The Eldoret National Polytechnic (TENP) and industry within Uasin Gishu County can collaborate to provide technical training. Several visits were made to selected companies participating in TVET training, in order to identify their best practices through one-to-one interviews, questionnaires, observation of activities and achievements, collection and interpretation of results. An attempt was also made to interpret enterprise-based TVET using theories and explanations applied successfully in other fields, as a means to achieve an original understanding using transferable and reliable methods of how TVET works, and why and where it is appropriate. The results indicated that linkages between TVET institutions and industry were weak. More consultations between the two parties as far as curriculum development, implementation, assessment and certification are concerned were needed.

description: Synthetic magnetism has been used to control charge neutral excitations for applications ranging from classical beam steering to quantum simulation. In optomechanics, radiation-pressure-induced parametric coupling between optical (photon) and mechanical (phonon) excitations may be used to break time-reversal symmetry, providing the prerequisite for synthetic magnetism. Here we design and fabricate a silicon optomechanical circuit with both optical and mechanical connectivity between two optomechanical cavities. Driving the two cavities with phase-correlated laser light results in a synthetic magnetic flux, which in combination with dissipative coupling to the mechanical bath, leads to nonreciprocal transport of photons with 35dB of isolation. Additionally, optical pumping with blue-detuned light manifests as a particle non-conserving interaction between photons and phonons, resulting in directional optical amplification of 12dB in the isolator through direction. These results indicate the feasibility of utilizing optomechanical circuits to create a more general class of nonreciprocal optical devices, and further, to enable novel topological phases for both light and sound on a microchip.

description: In a recent paper [Phys. Rev. B 89, 125418 (2014)], the authors argue that it is possible to map the electronic properties of twisted bilayer graphene to those of bilayer graphene in an in-plane magnetic field. However, their description of the low-energy dynamics of twisted bilayer graphene is restricted to the extended zone scheme and therefore neglects the effects of the superperiodic structure. If the energy spectrum is studied in the supercell Brillouin zone, we find that the comparison with an in-plane magnetic field fails because (i) the energy spectra of the two situations exhibit different symmetries and (ii) the low-energy spectra are very different.
