AbstractA method for traceability to SI for ac voltage and current based on high performance digitizers is presented. In contrast to the existing thermal-based methods, the proposed method utilizes direct traceability to quantum-based waveforms via the use of Josephson voltage systems. This allows not only a simplification of the traceability chain and reduced measurement times but also offers the potential for analysis of the ac voltage and current waveform spectral content, a feature which is not possible using thermal methods. Scaling of current and voltage is achieved by the use of current shunts and resistive voltage dividers respectively. Target operating ranges are up to 1 A and 100 V with a frequency range up to 1 kHz for both. The corresponding target uncertainty for this traceability route is 1 μV V−1and 2 μA A−1up to frequencies of 1 kHz. The traceability chain is described and various components are characterized to validate their suitability for this task. It is demonstrated that these uncertainty targets can be met under certain conditions. The use of multi-tone calibration waveforms is investigated to further reduce measurement time. An uncertainty analysis method based on simulation using real component performance data is demonstrated.

Published: September 2022

Abstract
Manufacturing has recently experienced increased adoption of optimised and fast solutions for checking product quality during fabrication, allowing for manufacturing times and costs to be significantly reduced. Due to the integration of machine learning algorithms, advanced sensors and faster processing systems, smart instruments can autonomously plan measurement pipelines, perform decisional tasks and trigger correctional actions as required. In this paper, we summarise the state of the art in smart optical metrology, covering the latest advances in integrated intelligent solutions in optical coordinate and surface metrology, respectively for the measurement of part geometry and surface texture. Within this field, we include the use of a priori knowledge and implementation of machine learning algorithms for measurement planning optimisation. We also cover the development of multi-sensor and multi-view instrument configurations to speed up the measurement process, as well as the design of novel feedback tools for measurement quality evaluation.
A little excitement across the horizon
Authors: Ng Keith K , Zhang Chen , Louko Jorma , Mann Robert B 
Published: September 2022

Abstract
We analyse numerically the transitions in an Unruh-DeWitt detector, coupled linearly to a massless scalar field, in radial infall in (3 + 1)-dimensional Schwarzschild spacetime. In the Hartle–Hawking and Unruh states, the transition probability attains a small local extremum near the horizon-crossing and is then moderately enhanced on approaching the singularity. In the Boulware state, the transition probability drops on approaching the horizon. The unexpected near-horizon extremum arises numerically from angular momentum superpositions, with a deeper physical explanation to be found.
Enhanced quantum efficiency in flexible AlGaN deep-ultraviolet light-emitting diodes by external strain

Abstract
Flexible electronic devices have great application potential in the field of next-generation consumer electronics. In this paper, we have demonstrated that applying external bending on AlGaN-based flexible deep-ultraviolet light-emitting diodes (DUV LEDs) can modulate the electrical characteristics of the quantum-well heterostructures. The internal quantum efficiency of DUV LEDs can be significantly improved by applying external strain on the device in bend-up mode. In addition, the peak emission of the DUV LEDs can be significantly tuned by bending the device into concave or convex curvatures. This desirable feature allows a single device to be applied in different environments and fields by applying external strain.
Securocratic state-building: the rationales, rebuttals, and risks behind the extraordinary rise of Rwanda after the genocide
Authors: McDoom Omar Shahabudin 
Published: September 2022

ABSTRACT
Both popular perspectives and theoretical characterizations of Rwanda’s remarkable trajectory following the genocide remain polarized more than a generation after the violence. The country has been hailed as a developmental state and denounced as an authoritarian ‘ethnocracy’. I introduce the concept of securocratic state-building in response to this polarization. The construct is intended to capture, first, the regime’s developmental but non-doctrinaire ambitions, synthesizing liberal and illiberal precepts; and second its prioritization of security over liberty, favouring stability over peace. I then draw on a set of interviews with key Rwandan opinion-makers drawn from across the country’s principal political and social divides to elicit the competing rationales given for each of three grand strategic choices made by the regime: why it eschewed competitive politics; why it sought to re-engineer society and efface ethnicity; and why it moved to modernize the state and the economy. The juxtaposition of these opposing opinions exposes a fundamental tension at the heart of the securocratic state-building model: the regime’s aspiration for unity is at odds with its preoccupation with security. This strategic contradiction, I argue, places a question mark over the long-term sustainability of the Rwanda model.

ABSTRACT
To investigate the effects of agar oligosaccharides (AO) on lipid metabolism, changes in obesity phenotypes and related molecular factors were evaluated in C57BL/6N mice fed a high-fat diet (HFD). When HFD-induced obese mice were fed AO, they lost weight. Also, fat accumulation in abdominal and liver tissues was lower in the AO groups than in the Vehicle group. Lipid droplet sizes in tissue sections were reduced by AO, and these observations were mirrored by serum lipid contents. To evaluate the effects of AO on lipid metabolism, lipogenesis and lipolysis-related factors were analyzed. The mRNA expressions of genes involved in lipogenesis, such as adipocyte-protein 2 (aP2) and fatty acid synthase (FAS), were reduced by AO administration, and the expressions of lipolysis-associated proteins, including perilipin, hormone-sensitive lipase (HSL), and fat triglyceride lipase (ATGL), were increased. Taken together, our results suggest that AO should be considered a valuable natural agent that inhibits obesity.
Towards a Synthesised Directional Map of the Stages of Innovation in Children’s Social Care

Abstract
There has been substantial investment by governments and charities in the UK in the development, diffusion and evaluation of innovative practice models and systems to safeguard and support vulnerable children, young people and families. However, understandings of the processes of innovation within the sector are still at a relatively early stage—for example, in relation to what might be expected or planned for at each stage of an innovation journey. As a result, best use may not always be made of opportunities to address deficiencies in provision. To inform this knowledge gap, the literature was reviewed regarding innovation processes and trajectories within children’s social care (statutory and voluntary settings) and within the field of social innovation more widely. Ten modellings of the stages of innovation were identified and synthesised into a directional map of six stages that might be commonly expected: mobilising, designing, developing, integrating, growing and system change. This trajectory framework poses key questions for innovators to consider at each stage to inform planning and determine if, when and how an innovation should progress further.
Strategic Complexity and the Value of Thinking
Authors: Gill David , Prowse Victoria 
Published: September 2022

Abstract
We leverage response-time data from repeated strategic interactions to measure the strategic complexity of a situation by how long people think on average when they face that situation (where we categorise situations according to characteristics of play in the previous round). We find that strategic complexity varies significantly across situations, and we find considerable heterogeneity in how responsive subjects’ thinking times are to complexity. We also study how variation in response times at the individual level affects success: when a subject thinks for longer than she would normally do in a particular situation, she wins less frequently and earns less.

Abstract
Fragmentation of healthcare systems through limited cross-speciality communication and intermittent, intervention-based care, without insight into follow-up and compliance, results in poor patient experiences and potentially contributes to suboptimal outcomes. Data-driven tools and novel technologies have the capability to address these shortcomings, but insights from all stakeholders in the care continuum remain lacking. A structured online questionnaire was given to respondents (n = 1432) in nine global geographies to investigate attitudes to the use of data and novel technologies in the management of vascular disease. Patients with coronary or peripheral artery disease (n = 961), physicians responsible for their care (n = 345), and administrators/healthcare leaders with responsibility for commissioning/procuring cardiovascular services (n = 126) were included. Narrative themes arising from the survey included patients’ desire for more personalized healthcare, shared decision-making, and improved communication. Patients, administrators, and physicians perceived and experienced deficiencies in continuity of care, and all acknowledged the potential for data-driven techniques and novel technologies to address some of these shortcomings. Further, physicians and administrators saw the ‘upstream’ segment of the care journey—before diagnosis, at point of diagnosis, and when determining treatment—as key to enabling tangible improvements in patient experience and outcomes. Finally, despite acceptance that data sharing is critical to the success of such interventions, there remains persistent issues related to trust and transparency. The current fragmented care continuum could be improved and streamlined through the adoption of advanced data analytics and novel technologies, including diagnostic and monitoring techniques. Such an approach could enable the refocusing of healthcare from intermittent contacts and intervention-only focus to a more holistic patient view.
Importance of Host Abundance and Microhabitat in Tick Abundance

Published: September 2022

AbstractTo reduce the risk of zoonoses, it is necessary to understand the infection process, including the ecology of animals and vectors (i.e., the ‘One Health’ approach). In temperate climates, ticks are the major vectors of zoonoses, so factors determining their abundance, such as host mammal abundance and microhabitat conditions, should be clarified. Sika deer (Cervus nippon) are a major tick host and are rapidly expanding their distribution in Japan. We established 12 plots along a gradient of sika deer abundance in Tochigi Prefecture, Japan. We monitored the occurrence of mammal species with camera traps and sampled questing ticks on a monthly basis by flagging along three transects (center of a trail, forest edge, and forest interior) at each site from April to November 2018. The camera traps recorded 12 mammal species, predominantly sika deer. Five Haemaphysalis species and three Ixodes species were sampled. The numbers of ticks sampled were explained by the photographic frequency of sika deer, and partly by that of other mammal species, depending on tick species and their developmental stages. The numbers of sampled adult and nymphal ticks were the highest at the forest edge, where vegetation cover was greatest. Thus, vegetation management in tick habitats and the control of sika deer populations may reduce tick abundance.

Published: September 2022

AbstractBackgroundCurrent diagnostic tests for pharyngitis do not distinguish between symptomatic group A Streptococcus (GAS) infection and asymptomatic colonization, resulting in over-diagnosis and unnecessary use of antibiotics. We assessed whether measures of host response could make this distinction.MethodsWe enrolled 18 children with pharyngitis having Centor scores of 4 or 5 and 21 controls without pharyngitis or other acute infections. Both groups had throat cultures, molecular tests for GAS and respiratory viruses and IgM serology for Epstein–Barr virus. Host response was evaluated with white blood cell count (WBC), C-reactive protein (CRP), procalcitonin (PCT), and sequencing of RNA from peripheral blood leukocytes.ResultsOf 18 cases, 11 had GAS pharyngitis, 3 had adenovirus pharyngitis and 4 had other pharyngitis. Among asymptomatic controls, 5 were positive for GAS. WBC, CRP, and PCT were higher in subjects with pharyngitis compared to asymptomatic controls including those with GAS. Transcriptional profiles from children with symptomatic GAS were clearly distinct from those of children in all other groups. The levels of two genes, CD177 and TLR5 each individually accurately distinguished between symptomatic and asymptomatic GAS. Optimal diagnostic sensitivity and specificity were achieved by the combination of CRP and PCT, and by each of the two gene markers.ConclusionIn this exploratory study, we showed that traditional measures of inflammation and markers of host gene expression distinguish between symptomatic and asymptomatic GAS. These results point to future rapid molecular approaches for improving the diagnosis of GAS pharyngitis, that may help reduce unnecessary antibiotic use.
Remembering Hodson’s Horse: Commemoration and the Indian Uprising of 1857–58
Authors: Cheshire Jim 
Published: September 2022

Abstract
This article presents analysis of the memorial to William Hodson in Lichfield Cathedral, designed by George Edmund Street between 1859 and 1862, focusing on the iconography of the monument and way that it was influenced by Muscular Christianity and ecclesiology. The attitude of Hodson and his brother George Hodson, who commissioned the monument, is examined through analysis of the publication that presented Hodson’s career to the Victorian public: Twelve Years of a Soldier’s Life in India (1859). The memorial raises urgent questions about the future of Victorian cultural heritage as it demonstrably misrepresents a highly symbolic event within British imperial history. Hodson was represented as a hero by Victorian ecclesiologists but is now seen by many as an unscrupulous and ruthless imperialist. This paper will demonstrate that the extraordinary form of the tomb was determined by an alteration to the design: the inclusion of a sculptural panel representing the ‘Surrender of the King of Delhi’. This change was instigated by the committee of the Ecclesiological Society headed by A. J. Beresford Hope. The panel turns a relatively peripheral event into a symbolic tableau: the surrender of Indian Islam to British Christianity, a distortion typical of British culture in the aftermath of the Indian Uprising of 1857–1858. The historiography of Hodson’s career shows that the tomb has acted as a focus for those wishing to perpetuate a conservative interpretation of Hodson’s career.
Comparing the super-Eddington accretion of SMC X-3 and RX J0209.6−7427 with Swift J0243.6+6124

ABSTRACT
We study the giant outbursts of SMC X-3 and RX J0209.6−7427 (hereafter RX J0209) to compare their super-Eddington accretion regime with that of Swift J0243.6+6124 (hereafter Swift J0243). The high double-peak profile of SMC X-3 is found to be 0.25 phase offset from that below 2.3 × 1038 erg s−1, which is similar to Swift J0243 (happened around 0.9 × 1038 erg s−1). The profile of RX J0209 shows a similar 0.25 phase offset between high double-peak and low double-peak around 1.25 × 1038 erg s−1. The 0.25 phase offset corresponds to a 90° angle change of the emission beam and strongly supports for a transition from a fan beam to a pencil beam. Their critical luminosities imply a surface magnetic field ∼4 × 1013 and 2 × 1013 G for SMC X-3 and RX J0209, respectively, based on the recently measured cyclotron line of Swift J0243. The spin-up rate and luminosity of SMC X-3 follows a relation of $\dot{\nu }\propto L^{0.94\pm 0.03}$, while that of RX J0209 follows $\dot{\nu }\propto L^{1.00\pm 0.03}$, which are similar to Swift J0243 and consistent with the prediction of a radiation-pressure-dominated disc. These results indicate that accretion columns are indeed formed above Eddington luminosity, and the population of ultraluminous X-ray pulsars likely corresponds to X-ray pulsars of highest magnetic field.
Rise and fall of silicate dust in RS Ophiuchi following the 2006 eruption

Published: September 2022

ABSTRACT
We present an analysis of archival Spitzer InfraRed Spectrograph (IRS) observations of the recurrent nova RS Ophiuchi obtained on several occasions, beginning about 7 months after the outburst in 2006. These data show atomic emission lines, absorption bands due to photospheric SiO, and the well-known silicate dust features at 9.7 and $18\, \mu$m. The dust emission, arising in the wind of the secondary star, is fitted by dusty models for mass-loss rates in the range 1.0–1.7 × 10−7 M⊙ yr−1. The silicate features are similar in profile to those seen in circumstellar environments of isolated late-type stars and some dusty symbiotic binaries, although the longer wavelength feature peaks at $17\, \mu$m, instead of the usual $18\, \mu$m, indicating peculiar grain properties. The dust features are variable, appearing stronger in 2006–2007 during outburst than in 2008–2009 when the system was in the quiescent state. This variability is attributed to changes in the ultraviolet output and the reformation of the accretion disc, although a decline in the mass-loss rate of the red giant secondary star could also play a role. Further observations, in the aftermath of the 2021 eruption, could provide a definitive conclusion.

ABSTRACT
Next-generation wide-field spectroscopic surveys will observe the infall regions around large numbers of galaxy clusters with high sampling rates for the first time. Here, we assess the feasibility of extracting the large-scale cosmic web around clusters using forthcoming observations, given realistic observational constraints. We use a sample of 324 hydrodynamic zoom-in simulations of massive galaxy clusters from TheThreeHundred project to create a mock-observational catalogue spanning 5R200 around 160 analogue clusters. These analogues are matched in mass to the 16 clusters targetted by the forthcoming WEAVE Wide-Field Cluster Survey (WWFCS). We consider the effects of the fibre allocation algorithm on our sampling completeness and find that we successfully allocate targets to 81.7 ${\rm {per \,cent}}\, \pm$ 1.3 of the members in the cluster outskirts. We next test the robustness of the filament extraction algorithm by using a metric, Dskel, which quantifies the distance to the filament spine. We find that the median positional offset between reference and recovered filament networks is Dskel = 0.13 ± 0.02 Mpc, much smaller than the typical filament radius of ∼ 1 Mpc. Cluster connectivity of the recovered network is not substantially affected. Our findings give confidence that the WWFCS will be able to reliably trace cosmic web filaments in the vicinity around massive clusters, forming the basis of environmental studies into the effects of pre-processing on galaxy evolution.
Heavy Rare Earth Elements and the Sources of Continental Flood Basalts
Authors: Heinonen Jussi S , Brown Eric L , Turunen Sanni T , Luttinen Arto V 
Published: September 2022

AbstractHeavy rare earth elements (HREEs) in mafic and ultramafic volcanic rocks are useful recorders of mantle source processes because their ratios are not easily modified by differentiation. Here we utilize REEBOX PRO, a simulator of adiabatic decompression melting of the mantle, to study the behavior of HREEs in the formation of continental flood basalt (CFB) parental magmas in the mantle. We simulate partial melting of depleted peridotite, pyrolitic peridotite, pyroxenite, and peridotite-pyroxenite mixtures at mantle potential temperatures of 1350–1650°C and lithospheric thicknesses of 50–150 km, and compare the results to natural data. Many large igneous provinces are typified by low-Ti and high-Ti CFBs with contrasting HREE patterns. Our results show that low-Ti CFBs originate mainly from peridotitic sources. Flat mid-ocean ridge basalt-like HREE patterns typical of low-Ti CFBs can be generated beneath thick lithosphere (~100 km), given that mantle potential temperatures are high (&gt;1500°C) and garnet is completely consumed from the source. We thus challenge the common interpretation that flat HREE patterns always indicate shallow sources for CFB parental magmas. High-Ti CFBs require pyroxenite-bearing sources (≥10%). Contrary to a common view, their steep oceanic island basalt-like HREE patterns can be generated beneath quite a thin lithosphere (~50 km), which is due to increased garnet stability in pyroxenite sources. When applied to CFBs of the Karoo large igneous province, the results are compatible with a model where a mantle plume penetrates a progressively thinning Gondwana lithosphere.
