description: The plant cell wall is a highly dynamic structure that changes in response to both environmental and developmental cues. It plays important roles throughout plant growth and development in determining the orientation and extent of cell expansion, providing structural support and acting as a barrier to pathogens. Despite the importance of the cell wall, the signaling pathways regulating its function are not well understood. Two partially redundant leucine-rich-repeat receptor-like kinases (LRR-RLKs), FEI1 and FEI2, regulate cell wall function in Arabidopsis thaliana roots; disruption of the FEIs results in short, swollen roots as a result of decreased cellulose synthesis. We screened for suppressors of this swollen root phenotype and identified two mutations in the putative mitochondrial pyruvate dehydrogenase E1α homolog, IAA-Alanine Resistant 4 (IAR4). Mutations in IAR4 were shown previously to disrupt auxin homeostasis and lead to reduced auxin function. We show that mutations in IAR4 suppress a subset of the fei1 fei2 phenotypes. Consistent with the hypothesis that the suppression of fei1 fei2 by iar4 is the result of reduced auxin function, disruption of the WEI8 and TAR2 genes, which decreases auxin biosynthesis, also suppresses fei1 fei2. In addition, iar4 suppresses the root swelling and accumulation of ectopic lignin phenotypes of other cell wall mutants, including procuste and cobra. Further, iar4 mutants display decreased sensitivity to the cellulose biosynthesis inhibitor isoxaben. These results establish a role for IAR4 in the regulation of cell wall function and provide evidence of crosstalk between the cell wall and auxin during cell expansion in the root.

description: We study the response of a class of topological systems to electromagnetic and gravitational sources, including torsion and curvature. By using the technology of anomaly polynomials, we derive the parity-odd response of a massive Dirac fermion in $d=2+1$ and $d=4+1$, which provides a simple model for a topological insulator. We discuss the covariant anomalies of the corresponding edge states, from a Callan-Harvey anomaly-inflow, as well as a Hamiltonian spectral flow point of view. We also discuss the applicability of our results to other systems such as Weyl semi-metals. Finally, using dimensional reduction from $d=4+1$, we derive the effective action for a $d=3+1$ time-reversal invariant topological insulator in the presence of torsion and curvature, and discuss its various physical consequences.

description: Spatially Resolved Transcriptomics (ST) is a recent molecular profiling technique that allows new insights into the spatial composition of transcriptome data, and thus offers new opportunities for the study of tumor heterogeneity and the composition of tumor microenvironment data (TME). In contrast to regular single-cell RNA-seq (scRNA) data, current ST techniques typically provide a multi-cell resolution, where the input of different cells is mixed for small spatial areas, or “spots”. Consequently, computational methods are needed to approximate the expression and type of the involved cells per ST spot. While algorithms like STdeconvolve and SpatialGE offer functions for spot-wise ST deconvolution, the Seurat pipeline uses an integration approach to predict the cell composition of ST spot data.
 We present a comparison of computational deconvolution and integration algorithms for spatial transcriptomics data on a set of eight original human 10X Visium retinoblastoma samples, and published murine and human 10X Visium spatial transcriptomics data. For each original sample, a matching single-cell RNA-seq (scRNA) retinoblastoma sample with detailed cluster annotations was available for comparison purposes and as computational reference dataset, if applicable. We evaluated the effects of different algorithm parameters on the deconvolution results, assessed the proportions of retinoblastoma and TME cell types in the ST and scRNA data, and tested the chosen algorithms' run time and general usability.

description: The enteroendocrine cell is the cornerstone of gastrointestinal chemosensation. In the intestine and colon, this cell is stimulated by nutrients, tastants that elicit the perception of flavor, and bacterial by-products; and in response, the cell secretes hormones like cholecystokinin and peptide YY – both potent regulators of appetite. The development of transgenic mice with enteroendocrine cells expressing green fluorescent protein has allowed for the elucidation of the apical nutrient sensing mechanisms of the cell. However, the basal secretory aspects of the enteroendocrine cell remain largely unexplored, particularly because a complete account of the enteroendocrine cell ultrastructure does not exist. Today, the fine ultrastructure of a specific cell can be revealed in the third dimension thanks to the invention of serial block face scanning electron microscopy (SBEM). Here, we bridged confocal microscopy with SBEM to identify the enteroendocrine cell of the mouse and study its ultrastructure in the third dimension. The results demonstrated that 73.5% of the peptide-secreting vesicles in the enteroendocrine cell are contained within an axon-like basal process. We called this process a neuropod. This neuropod contains neurofilaments, which are typical structural proteins of axons. Surprisingly, the SBEM data also demonstrated that the enteroendocrine cell neuropod is escorted by enteric glia – the cells that nurture enteric neurons. We extended these structural findings into an in vitro intestinal organoid system, in which the addition of glial derived neurotrophic factors enhanced the development of neuropods in enteroendocrine cells. These findings open a new avenue of exploration in gastrointestinal chemosensation by unveiling an unforeseen physical relationship between enteric glia and enteroendocrine cells.

description: IntroductionPalliative care is rarely accessible in rural sub-Saharan Africa. Partners In Health and the Malawi government established the Neno Palliative Care Program (NPCP) to provide palliative care in rural Neno district. We conducted a situation analysis to evaluate early NPCP outcomes and better understand palliative care needs, knowledge, and preferences.MethodsEmploying rapid evaluation methodology, we collected data from 3 sources: 1) chart review of all adult patients from the NPCP’s first 9 months; 2) structured interviews with patients and caregivers; 3) semi-structured interviews with key stakeholders.ResultsThe NPCP enrolled 63 patients in its first 9 months. Frequent diagnoses were cancer (n = 50, 79%) and HIV/AIDS (n = 37 of 61, 61%). Nearly all (n = 31, 84%) patients with HIV/AIDS were on antiretroviral therapy. Providers registered 112 patient encounters, including 22 (20%) home visits. Most (n = 43, 68%) patients had documented pain at baseline, of whom 23 (53%) were treated with morphine. A majority (n = 35, 56%) had ≥1 follow-up encounter. Mean African Palliative Outcome Scale pain score decreased non-significantly between baseline and follow-up (3.0 vs. 2.7, p = 0.5) for patients with baseline pain and complete pain assessment documentation. Providers referred 48 (76%) patients for psychosocial services, including community health worker support, socioeconomic assistance, or both. We interviewed 36 patients referred to the NPCP after the chart review period. Most had cancer (n = 19, 53%) or HIV/AIDS (n = 10, 28%). Patients frequently reported needing income (n = 24, 67%) or food (n = 22, 61%). Stakeholders cited a need to make integrated palliative care widely available.ConclusionsWe identified a high prevalence of pain and psychosocial needs among patients with serious chronic illnesses in rural Malawi. Early NPCP results suggest that comprehensive palliative care can be provided in rural Africa by integrating disease-modifying treatment and palliative care, linking hospital, clinic, and home-based services, and providing psychosocial support that includes socioeconomic assistance.

description: IntroductionNepal has one of the highest cervical cancer rates in South Asia. Only a few studies in populations from urban areas have investigated type specific distribution of human papillomavirus (HPV) in Nepali women. Data on high-risk HPV (HR-HPV) types are not currently available for rural populations in Nepal. We aimed to assess the distribution of HR- HPV among rural Nepali women while assessing self-collected and clinician-collected cervico-vaginal specimens as sample collection methods for HPV screening.MethodsStudy participants were recruited during a health camp conducted by Nepal Fertility Care Center in Achham District of rural far western Nepal. Women of reproductive age completed a socio-demographic and clinical questionnaire, and provided two specimens; one cervical-vaginal specimen using a self-collection method and another cervical specimen collected by health camp auxiliary nurse midwives during a pelvic examination. All samples were tested for 14 different HR-HPV mRNA and also specific for HPV16/18/45 mRNA.ResultsOf 261 women with both clinician- and self-collected cervical samples, 25 tested positive for HR-HPV, resulting in an overall HR-HPV prevalence of 9.6% (95% confidence Interval [CI]: 6.3–13.8). The overall Kappa value assessing agreement between clinician- and self-collected tests was 0.62 (95% CI: 0.43–0.81), indicating a “good” level of agreement. Abnormal cytology was reported for 8 women. One woman identified with squamous cell carcinoma (SCC), and 7 women with high grade squamous intraepithelial lesions (HSIL). Seven of the 8 women tested positive for HR-HPV (87.5%) in clinician-collected samples and 6 in self-collected samples (75.0%).ConclusionThis is the first study to assess HR-HPV among rural Nepali women. Self-collected sampling methods should be the subject of additional research in Nepal for screening HR-HPV, associated with pre-cancer lesions and cancer, in women in rural areas with limited access to health services.

description: Mechanisch flexible Kristalle können gebogen werden, ohne dabei zu zerbrechen. Je nach Art der Verformung können sie als mechanisch plastisch (irreversibel) oder elastisch (reversibel) biegbar eingestuft werden. Die verbesserten mechanischen Eigenschaften machen sie zu einer faszinierenden neuen Klasse von Materialien. Sie sind vielversprechend für die Entwicklung neuer funktioneller Bauelemente wie zum Beispiel fortschrittliche optoelektronische Elemente, intelligente Sensoren und künstliche Muskeln. Die derzeitigen Herausforderungen auf dem Forschungsgebiet der mechanisch flexiblen Kristalle umfassen ihre eingeschränkte Verfügbarkeit, ein fehlendes Verständnis für den Biegemechanismus und die Erforschung möglicher Anwendungen. Die vorliegende Arbeit befasst sich mit allen drei Bereichen und zielt darauf ab, 1) robuste Strategien zu entwickeln, um den Zugang zu mechanisch flexiblen Kristallen zu erleichtern, 2) ein atomistisches Biegemodell für einen mechanisch elastischen Kristall auf Grundlage von μ-fokussierter Einkristall-Röntgenbeugung und Dichtefunktionaltheorie-Berechnungen zu entwickeln und 3) die Lichtleitereigenschaften mechanisch flexibler Kristalle zu untersuchen, einschließlich der Verwendung elastischer und plastischer Kristalle und der Herstellung einer miniaturisierten photonisch integrierten Schaltung.
description: Mechanically flexible crystals can be bent without breaking. Depending on the nature of the deformation, they can be classified as mechanically plastic (irreversible) or elastic (reversible) bendable. The improved mechanical properties make them a fascinating new class of materials. They are promising materials for the development of new functional materials, including advanced optoelectronics, smart sensors, and artificial muscles. Current challenges in the research field of mechanically flexible crystals are the limited accessibility of these materials, the lack of mechanistic understanding of the bending mechanism, and the investigation of potential applications. The present work addresses all three areas with the aim of 1) developing robust strategies to facilitate access to mechanically flexible crystals, 2) developing an atomistic bending model for mechanically elastic crystals based on μ-focused single crystal X-ray diffraction (SCXRD) and density functional theory (DFT) calculations, and 3) investigating the waveguide properties of mechanically flexible crystals, including the use of elastic and plastic crystals and the fabrication of a micro-scale photonic integrated circuit.

description: Cities are at the heart of global challenges and its solutions. When occupying only 3% of Earth’s land, they are both the engines of economic growth with 80% of the global GDP but at the same time cities are emitting 75% of global green house gases. The aim of this paper was to focus on how different city development programs have been developing and how they are supporting the city’s strategic goals. This paper has shown self-assessment results of 37 projects from four different programs in the city of Tampere. The projects were evaluated against five themes: people, planet, propagation, governance and scalability/replicability. The results showed that the environmental indicators had high scores. Also, the governance focus had a high scores in most of the projects. The people focus was highest in project themes on smart cities. Some of the ecological projects were in nature very technical, which is the reason why they did not score that high in people theme. The results showed clearly that the scalability and replicability are becoming very important elements in the existing and coming projects in cities. This could be also clearly seen in the analyses where the scalability and replicability of the different projects has been important in last 5-10 years and it seem that especially in the recent years the importance has a high impact. From our study we could initially conclude that the program based approach in city’s economic development seems to provide one strand of continuation in implementation of the city’s economic development policy and that the impact of its implementation improves. The hierarchical roles of different sets of projects as well as that of the sub-ecosystems that have carried out the project(s) indicates that the ecosystem approach is a useful one. The results also highllighted the role of programs as platforms for innovation and co-creation between citizens, companies, research organizations and public sector. In these ecosystems value is created to all stakeholders. The value may be direct financial value but may well be also indirect such as R&D related, community value etc. The role of the cities is very important in this ecosystem value creation as they are considered to be a neutral body with focus on the public interest, not a vested one. As the role of cities is growing to be paramount also in innovation, this should be reflected in regional, national and EU level innovation policies, funding schemes and regulations as well as in execution of innovations.

description: Genotype imputation has become standard practice in modern genetic studies. As sequencing-based reference panels continue to grow, increasingly more markers are being well or better imputed but at the same time, even more markers with relatively low minor allele frequency are being imputed with low imputation quality. Here, we propose new methods that incorporate imputation uncertainty for downstream association analysis, with improved power and/or computational efficiency. We consider two scenarios: I) when posterior probabilities of all potential genotypes are estimated; and II) when only the one-dimensional summary statistic, imputed dosage, is available. For scenario I, we have developed an expectation-maximization likelihood-ratio test for association based on posterior probabilities. When only imputed dosages are available (scenario II), we first sample the genotype probabilities from its posterior distribution given the dosages, and then apply the EM-LRT on the sampled probabilities. Our simulations show that type I error of the proposed EM-LRT methods under both scenarios are protected. Compared with existing methods, EM-LRT-Prob (for scenario I) offers optimal statistical power across a wide spectrum of MAF and imputation quality. EM-LRT-Dose (for scenario II) achieves a similar level of statistical power as EM-LRT-Prob and, outperforms the standard Dosage method, especially for markers with relatively low MAF or imputation quality. Applications to two real data sets, the Cebu Longitudinal Health and Nutrition Survey study and the Women’s Health Initiative Study, provide further support to the validity and efficiency of our proposed methods.

description: The increasing relevance of security within the Internet has led to a growing demand to ensure the confidentiality, integrity and availability of data. Nowadays, former HTTP traffic is encrypted and is now referred to as HTTPS traffic. Thereby, TLS is used to protect data in transit and has become a state-of-the-art protocol. Research in the field of energy consumption of secure communication channels has become increasingly important in scientific studies since the early 2000s. However, it predominantly focused on Internet-of-Things devices and battery-powered devices, e.g. smartphones, to increase battery life. In recent years, energy efficiency is becoming more important through the growing environmental awareness and climate change. The field of information security has to provide energy-efficient solutions now, not only for battery-oriented devices, but also those directly connected with the power grid, e.g. servers or PCs. The goal of this thesis is to determine the impact on energy consumption encrypting HTTP with TLS, i.e. HTTPS. In order to achieve this, we pursue a two phased approach. In the first phase, we evaluate various measurement environments for this purpose. In the second phase, we conduct a comparative analysis between different cipher suites regarding their energy efficiency and execution time. This research is one of the first to conduct such an analysis on a plug-socket device. Our goal is to determine whether and which cipher suites have a lower energy consumption and might pursue the way for energy savings in the future.

description: In this work we address two questions concerning Grover's algorithm. In the first we give an answer to the question how to employ Grover's algorithm for actual search over database. We introduce a quantum model of an unordered phone book (quantum database) with programmable queries to search in the phone book either for a number, or for a name. In the second part we investigate how successful the algorithm can be if the number of elements of the database is not known precisely. This question reduces to analysis of the distinguishability of states occurring during Grover's algorithm. We found that using unambiguous discrimination scheme even a seemingly good guess, that is close to the optimal one can result in a rather small success rate.

description: In einer zunehmend digitalen Wissenschaftslandschaft ist die dauerhafte und verlässliche Identifizierung der mit Forschungsprozessen verknüpften Ressourcen, seiner Akteure und ihrer Forschungsprodukte mittels Persistent Identifiern (PIDs) unerlässlich geworden. Mit der wachsenden Bedeutung von PIDs im Forschungsalltag und zunehmend auch in kulturellen Kontexten erhöhen sich aber auch die Anforderungen an deren effiziente Nutzbarkeit. Gleichzeitig werden die Nutzenden mit einer großen Vielfalt sehr unterschiedlicher Angebote an PID-Systemen und ihrer Einsatzmöglichkeiten konfrontiert. Das von der Deutschen Forschungsgemeinschaft (DFG) für 36 Monate geförderte Projekt „PID Network Deutschland“ verfolgt daher das Ziel, ein Netzwerk bereits bestehender und sich aktuell formierender Agierender rund um die persistente Identifikation von Personen, Organisationen, Publikationen, Ressourcen und Infrastrukturen im Bereich der digitalen Kommunikation in Wissenschaft und Kultur zu etablieren. Hierdurch soll nicht nur die Verbreitung und Vernetzung von PID-Systemen in Deutschland, sondern auch deren Einbettung in internationale Infrastrukturen, wie Wissensgraphen, optimiert werden. Die Erkenntnisse aus dem Projekt werden in Empfehlungen in einer nationalen PID-Roadmap für Deutschland münden und somit die Vision einer vernetzten und offenen Wissenschaftslandschaft schärfen. Unter diesem Leitsatz gibt das Poster einen Überblick über die verschiedenen Anwendungsfälle von PIDs, die im Projektkontext fokussiert werden. Dadurch sollen der Status Quo der gegenwärtigen PID-Landschaft veranschaulicht und potenzielle Handlungsbedarfe identifiziert werden. Der Projektantrag gibt weitere Einblicke in die Ziele des Vorhabens. Partnerinstitutionen im Projekt sind DataCite, die Deutsche Nationalbibliothek, das Helmholtz Open Science Office, die Universitätsbibliothek Bielefeld und die Technische Informationsbibliothek (TIB).

description: Barrier islands are complex and dynamic systems that provide critical ecosystem services to coastal populations. Stability of these systems is threatened by rising sea level and the potential for coastal storms to increase in frequency and intensity. Recovery of dune-building grasses following storms is an important process that promotes topographic heterogeneity and long-term stability of barrier islands, yet factors that drive dune recovery are poorly understood. We examined vegetation recovery in overwash zones on two geomorphically distinct (undisturbed vs. frequently overwashed) barrier islands on the Virginia coast, USA. We hypothesized that vegetation recovery in overwash zones would be driven primarily by environmental characteristics, especially elevation and beach width. We sampled species composition and environmental characteristics along a continuum of disturbance from active overwash zones to relict overwash zones and in adjacent undisturbed environments. We compared species assemblages along the disturbance chronosequence and between islands and we analyzed species composition data and environmental measurements with Canonical Correspondence Analysis to link community composition with environmental characteristics. Recovering and geomorphically stable dunes were dominated by Ammophila breviligulata Fernaud (Poaceae) on both islands while active overwash zones were dominated by Spartina patens (Aiton) Muhl. (Poaceae) on the frequently disturbed island and bare sand on the less disturbed island. Species composition was associated with environmental characteristics only on the frequently disturbed island (p = 0.005) where A. breviligulata was associated with higher elevation and greater beach width. Spartina patens, the second most abundant species, was associated with larger sediment grain size and greater sediment size distribution. On the less frequently disturbed island, time since disturbance was the only factor that affected community composition. Thus, factors driving the abundance of dune-building grasses and subsequent recovery of dunes varied between the two geomorphically distinct islands.

description: In this paper we study the self-organization process of adiabatic shear bands in OFHC copper and HY-100 steel taking into account strain hardening factor. Starting from mathematical model we present new numerical approach, which is based on Courant -- Isaacson -- Rees scheme that allows one to simulate fully localized plastic flow. To prove accuracy and efficiency of our method we give solutions of two benchmark problems. Next we apply the proposed method to investigate such quantitative characteristics of self-organization process of ASB as average stress, temperature, localization time and distance between ASB. Then we compare the obtained results with theoretical predictions by other authors.

description: Bisphenol A (BPA) exposure results in numerous developmental and functional abnormalities in reproductive organs in rodent models, but limited data are available regarding BPA effects in the primate uterus. To determine if maternal oral BPA exposure affects fetal uterine development in a non-human primate model, pregnant rhesus macaques carrying female fetuses were exposed orally to 400 µg/kg BPA or vehicle control daily from gestation day (GD) 50–100 or GD100–165. Fetal uteri were collected at the completion of treatment (GD100 or GD165); tissue histology, cell proliferation, and expression of estrogen receptor alpha (ERα) and progesterone receptor (PR) were compared to that of controls. Gene expression analysis was conducted using rhesus macaque microarrays. There were no significant differences in histology or in the percentage of cells expressing the proliferation marker Ki-67, ERα, or PR in BPA-exposed uteri compared to controls at GD100 or GD165. Minimal differences in gene expression were observed between BPA-exposed and control GD100 uteri. However, at GD165, BPA-exposed uteri had significant differences in gene expression compared to controls. Several of the altered genes, including HOXA13, WNT4, and WNT5A, are critical for reproductive organ development and/or adult function. We conclude that second or third trimester BPA exposure does not significantly affect fetal uterus development based on morphological, proliferation, and steroid hormone receptor assessments. However, differences in expression of key developmental genes after third trimester exposure suggest that BPA could alter transcriptional signals influencing uterine function later in life.

$SU(2)\times U(1)$ gauge invariance and the shape of new physics in rare $B$ decays

description: New physics effects in $B$ decays are routinely modeled through operators invariant under the strong and electromagnetic gauge symmetries. Assuming the scale for new physics is well above the electro-weak scale, we further require invariance under the full Standard-Model gauge symmetry group. Retaining up to dimension-6 operators, we unveil new constraints between different new-physics operators that are assumed to be independent in the standard phenomenological analyses. We illustrate this approach by analyzing the constraints on new physics from rare $B_{q}$ (semi-)leptonic decays.

description: The green turtle, Chelonia mydas, is an endangered marine chelonian with a circum-global distribution. Reference blood parameter intervals have been published for some chelonian species, but baseline hematology, biochemical, and blood gas values are lacking from the Galapagos sea turtles. Analyses were done on blood samples drawn from 28 green turtles captured in two foraging locations on San Cristóbal Island (14 from each site). Of these turtles, 20 were immature and of unknown sex; the other eight were males (five mature, three immature). A portable blood analyzer (iSTAT) was used to obtain near immediate field results for pH, lactate, pO2, pCO2, HCO3−, Hct, Hb, Na, K, iCa, and Glu. Parameter values affected by temperature were corrected in two ways: (1) with standard formulas; and (2) with auto-corrections made by the iSTAT. The two methods yielded clinically equivalent results. Standard laboratory hematology techniques were employed for the red and white blood cell counts and the hematocrit determination, which was also compared to the hematocrit values generated by the iSTAT. Of all blood analytes, only lactate concentrations were positively correlated with body size. All other values showed no significant difference between the two sample locations nor were they correlated with body size or internal temperature. For hematocrit count, the iSTAT blood analyzer yielded results indistinguishable from those obtained with high-speed centrifugation. The values reported in this study provide baseline data that may be useful in comparisons among populations and in detecting changes in health status among Galapagos sea turtles. The findings might also be helpful in future efforts to demonstrate associations between specific biochemical parameters and disease.

description: Genetic factors influence the effects of fluoride (F) on amelogenesis and bone homeostasis but the underlying molecular mechanisms remain undefined. A label-free proteomics approach was employed to identify and evaluate changes in bone protein expression in two mouse strains having different susceptibilities to develop dental fluorosis and to alter bone quality. In vivo bone formation and histomorphometry after F intake were also evaluated and related to the proteome. Resistant 129P3/J and susceptible A/J mice were assigned to three groups given low-F food and water containing 0, 10 or 50 ppmF for 8 weeks. Plasma was evaluated for alkaline phosphatase activity. Femurs, tibiae and lumbar vertebrae were evaluated using micro-CT analysis and mineral apposition rate (MAR) was measured in cortical bone. For quantitative proteomic analysis, bone proteins were extracted and analyzed using liquid chromatography-electrospray ionization-tandem mass spectrometry (LC-ESI-MS/MS), followed by label-free semi-quantitative differential expression analysis. Alterations in several bone proteins were found among the F treatment groups within each mouse strain and between the strains for each F treatment group (ratio ≥1.5 or ≤0.5; p<0.05). Although F treatment had no significant effects on BMD or bone histomorphometry in either strain, MAR was higher in the 50 ppmF 129P3/J mice than in the 50 ppmF A/J mice treated with 50 ppmF showing that F increased bone formation in a strain-specific manner. Also, F exposure was associated with dose-specific and strain-specific alterations in expression of proteins involved in osteogenesis and osteoclastogenesis. In conclusion, our findings confirm a genetic influence in bone response to F exposure and point to several proteins that may act as targets for the differential F responses in this tissue.

description: The role of anisotropic thermal diffusivity on tearing mode stability is analysed in general toroidal geometry. A dispersion relation linking the growth rate to the tearing mode stability parameter, Delta, is derived. By using a resistive MHD code, modified to include such thermal transport, to calculate tearing mode growth rates, the dispersion relation is employed to determine Delta in situations with finite plasma pressure that are stabilised by favourable average curvature in a simple resistive MHD model. We also demonstrate that the same code can also be used to calculate the basis-functions [C J Ham, et al, Plasma Phys. Control. Fusion 54 (2012) 105014] needed to construct Delta.
