description: Studying molecular gas properties in merging galaxies gives us important clues to the onset and evolution of interaction-triggered starbursts. NGC4194 is particularly interesting to study since its FIR-to-CO luminosity ratio rivals that of ULIRGs,despite its lower luminosity compared to ULIRGs, which indicates a high star formation efficiency that is relative to even most spirals and ULIRGs.We study the molecular medium at an angular resolution of 0.65"x .52" through our observations of CO2-1 emission using the SMA. We compare our CO2-1 maps with optical HST and high angular resolution radio continuum images to study the relationship between molecular gas and other components of the starburst region. The molecular gas is tracing the complicated dust lane structure of NGC4194 with the brightest emission being located in an off-nuclear ring-like structure with ~320pc radius, the Eye of the Medusa. The bulk CO emission of the ring is found south of the kinematical center of NGC4194. The northern tip of the ring is associated with the galaxy nucleus, where the radio continuum has its peak. A prominent, secondary emission maximum in the radio continuum is located inside the molecular ring. This suggests that the morphology of the ring is partially influenced by massive supernova explosions. From the combined evidence, we propose that the Eye of the Medusa contains a shell of swept up material where we identify a number of giant molecular associations. We propose that the Eye may be the site of an efficient starburst of 5-7M_sun/yr, but it would still constitute only a fraction of the 30-50M_sun/yr SFR of NGC4194. Furthermore, we find that ~50% of the molecular mass of NGC4194 is found in extended filamentary-like structures tracing the minor and major axis dust lanes. We suggest that molecular gas is transported along these lanes providing the central starburst region with fuel.

description: Objective: The study explores the attitudes of people with chronic health conditions towards the use of group-based telerehabilitation.Design: A qualitative research study.Setting: The setting involved semi-structured focus groups via videoconferencing software.Participants: A purposive sample of 18 people with chronic health conditions including cardiorespiratory, neurological and musculoskeletal conditions was recruited via national patient advocacy and support groups in Ireland and clinical contacts. The sample included both those who had, and had not, previously engaged in telerehabilitation programmes.Procedures: An online questionnaire collected demographic information and data regarding previous telerehabilitation participation and telerehabilitation preferences. Focus groups were conducted using video-conferencing software, in accordance with the Consolidated Criteria for Reporting Qualitative Research (COREQ) Checklist, and analysed using thematic analysis following Braun and Clarke’s methodology. Findings were triangulated with quantitative questionnaire data.Results: Four focus groups were conducted including participants with chronic cardiorespiratory (n=8), neurological (n=6) and musculoskeletal (n=4) conditions. Three themes were identified regarding telerehabilitation: (a) benefits and facilitators (including convenience, increased service accessibility, social connection and technological support), (b) challenges and barriers (including technological access and literacy, limited ‘hands-on’ therapy, safety concerns and social limitations), and (c) preferences (regarding mode of delivery, content, duration and generic programmes for mixed-condition groups).Conclusions: Telerehabilitation is convenient for people with chronic conditions; however, concerns exist regarding the use of technology and the limitations of this healthcare delivery method. The role of telerehabilitation is valued, and future programmes should acknowledge patient preferences including a hybrid model of care, exercise and educational content, social interaction and synchronous components.

description: We prove a result, announced by F. Nazarov, L. Polterovich and M. Sodin that exhibits a relation between the average local growth of a Laplace eigenfunction on a closed surface and the global size of its nodal set. More precisely, we provide a lower and an upper bound to the Hausdorff measure of the nodal set in terms of the expected value of the growth exponent of an eigenfunction on disks of wavelength like radius. Combined with Yau's conjecture, the result implies that the average local growth of an eigenfunction on such disks is bounded by constants in the semi-classical limit. We also obtain results that link the size of the nodal set to the growth of solutions of planar Schrödinger equations with small potential.

Тольятти (Самарская область). Исследования были проведены в период открытой воды в 2013-2015 гг. Во всех озерах в настоящее время наблюдаются признаки высокой степени антропогенного эвтрофирования. По сравнению с началом 1990-х гг. продуктивность озер увеличилась, и в настоящее время ее уровень изменяется от высокоэвтрофного до гипертрофного в ряду озер: Дачное Восьмерка Прудовиков Б. Васильевское. Величины индекса Карлсона (TSIP) в значительной части проб превышают 80. В оз. Прудовиков и в оз. Б. Васильевское развитие фитопланктона лимитировано фосфором. В оз. Восьмерка и Дачное запасы фосфора в водной толще велики и при изменении экологической ситуации в них возможно увеличение "цветения" фитопланктона.

description: With novel developments in sequencing technologies, time-sampled data are becoming more available and accessible. Naturally, there have been efforts in parallel to infer population genetic parameters from these datasets. Here, we compare and analyze four recent approaches based on the Wright-Fisher model for inferring selection coefficients (s) given effective population size (Ne), with simulated temporal datasets. Furthermore, we demonstrate the advantage of a recently proposed ABC-based method that is able to correctly infer genome-wide average Ne from time-serial data, which is then set as a prior for inferring per-site selection coefficients accurately and precisely. We implement this ABC method in a new software and apply it to a classical time-serial dataset of the medionigra genotype in the moth Panaxia dominula. We show that a recessive lethal model is the best explanation for the observed variation in allele frequency by implementing an estimator of the dominance ratio (h).

description: We report on a simple method of locking a laser to a birefringent cavity using polarization spectroscopy. The birefringence of the resonator permits the simple extraction of an error signal by using one polarization state as a phase reference for another state. No modulation of the light or the resonator is required, reducing the complexity of the laser locking setup. This method of producing an error signal can be used on most birefringent optical resonators, even if the details of birefringence and eigenpolarizations are not known. This technique is particularly well suited for fiber ring resonators due to the inherent birefringence of the fiber and the unknown nature of that birefringence. We present an experimental demonstration of this technique using a fiber ring.

description: empirical evidence in support of the argument that keeping real exchange rate persistently devalued may lead to a permanent higher level of inflation have been provided (Kamin, 1985; Calvo et al. 1994). However, probably because of the relatively recent origin of serious exchange rate depreciation in sub-Saharan Africa countries especially Nigeria, when compared with other regions e.g. Latin America and Asia, not many studies have been reported on the subject. The existing studies on effect of persistent exchange-rate depreciation in Nigeria are based on either regression or simulation approach rather than VAR approach. This present study intends to fill these gaps by not only focusing the study on Nigeria but also adopting restricted vector Autoregressive model thereby providing basis for comparison with existing results obtained for other countries.

description: Online socio-technical systems can be studied as proxy of the real world to investigate human behavior and social interactions at scale. Here we focus on Instagram, a media-sharing online platform whose popularity has been rising up to gathering hundred millions users. Instagram exhibits a mixture of features including social structure, social tagging and media sharing. The network of social interactions among users models various dynamics including follower/followee relations and users' communication by means of posts/comments. Users can upload and tag media such as photos and pictures, and they can "like" and comment each piece of information on the platform. In this work we investigate three major aspects on our Instagram dataset: (i) the structural characteristics of its network of heterogeneous interactions, to unveil the emergence of self organization and topically-induced community structure; (ii) the dynamics of content production and consumption, to understand how global trends and popular users emerge; (iii) the behavior of users labeling media with tags, to determine how they devote their attention and to explore the variety of their topical interests. Our analysis provides clues to understand human behavior dynamics on socio-technical systems, specifically users and content popularity, the mechanisms of users' interactions in online environments and how collective trends emerge from individuals' topical interests.

description: In recent years, proximity labeling has established itself as an unbiased and powerful approach to map the interactome of specific proteins. While physiological expression of labeling enzymes is beneficial for the mapping of interactors, generation of the desired cell lines remains time-consuming and challenging. Using our established pipeline for rapid generation of C- and N-terminal CRISPR-Cas9 knock-ins (KIs) based on antibiotic selection, we were able to compare the performance of commonly used labeling enzymes when endogenously expressed. Endogenous tagging of the µ subunit of the AP-1 complex with TurboID allowed identification of known interactors and cargo proteins that simple overexpression of a labeling enzyme fusion protein could not reveal. We used the KI-strategy to compare the interactome of the different adaptor protein (AP) complexes and clathrin and were able to assemble lists of potential interactors and cargo proteins that are specific for each sorting pathway. Our approach greatly simplifies the execution of proximity labeling experiments for proteins in their native cellular environment and allows going from CRISPR transfection to mass spectrometry analysis and interactome data in just over a month.

We can reproduce the experimental data ${\rm Br}\left(D_{sJ}^*(2860)\to D^*K\right)/{\rm Br}\left(D_{sJ}^*(2860)\to D K\right) =1.10 \pm 0.15 \pm 0.19$ with suitable hadronic coupling constants, the assignment of the $D_{sJ}^*(2860)$ as the $D_{s3}^*(2860)$ is favored, the chiral symmetry breaking corrections are large. Furthermore, we obtain the analytical expressions of the decay widths, which can be confronted with the experimental data in the future to fit the unknown coupling constants. The predictions of the ratios among the decay widths can be used to study the decay properties of the $D_{s3}^*(2860)$ and $D_{s1}^*(2860)$ so as to identify them unambiguously. On the other hand, if the chiral symmetry breaking corrections are small, the large ratio $R=1.10 \pm 0.15 \pm 0.19$ requires that the $D_{sJ}^*(2860)$ consists of at least four resonances $D_{s1}^*(2860)$, $D_{s2}^*(2860)$, $D_{s2}^{*\prime}(2860)$, $D_{s3}^*(2860)$.

description: Inequalities and poverty are important drivers of social exclusion, while conflict, social unrest and instability are its manifestation. The preponderance of conflicts in poor and unequal societies has long been documented in the literature.1 As Nagel succinctly argues, “political discontent and its consequences – protest, instability, violence, revolution – depend not only on the absolute level of economic well-being, but also on the distribution of wealth”. According to the Kuznets’ inverted-U theory, a high level of income inequality radicalises the proletariat, enhances class polarisation and reduces the tolerance of the bourgeoisie for low-income group participation in political and decisionmaking processes.

Higher education

description: AI tools such as ChatGPT have dominated higher education discourse since being released in late 2022. While early indications are that AI generated essays are possible to spot (a common syntax, citations are often fake, a lack of capacity to focus on local context), ChatGPT is the first in a wave of AI tools made generally available, and improvements are inevitable. Microsoft and Google are integrating AI into their products. The immediate future will see a lot of prompts to engage AI into normal workflows such as document production. Discourse regarding AI and higher education has resulted in a consideration of three possible pathways: to ignore it, to try to avoid it, or to embrace it. As ignoring it and avoiding it are unlikely to be fruitful, the remaining option is to (cautiously) embrace AI and its role in higher education.

description: The need to avert the negative effects of unemployment has made the tackling of unemployment problems to feature very prominently in the development objectives of many developing countries. Incidentally, most of these countries' economies are also characterized by low productivity. Thus, it seems obvious to many policy makers that there must be a straight forward connection between productivity and employment/unemployment. However, the theoretical linkage between productivity and unemployment is yet to be settled in the literature. While some researchers posit that higher productivity may increase unemployment (e.g. Diachavbre, 1991; Krugman, 1994), some others argue that it could increase employment (e.g Yesufu, 1984; Akerele, 1994; CEC, 1993). In view of the unfolding reality coupled with the protracted debates this paper attempts to examine the linkage between productivity and unemployment. Specifically, it examines the dimensions of productivity and unemployment in Nigeria as well as the direction of causality between them. To this end, the rest of the paper is organized thus. Following this introduction is part II, which examines the conceptual and theoretical is sues. Part III discusses the profile of productivity and unemployment in Nigeria while the empirical link between them is examined in part IV. The final part contains the policy implications and conclusions.

description: The economic landscape of most African countries depends essentially on the dynamics of climate change. Key sectors driving their economic performance and livelihoods such as agriculture, forestry, energy, tourism, coastal and water resources are highly vulnerable to climate change. This article examines the empirical linkage between economic growth and climate change in Africa. Using annual data for 34 countries from 1961 to 2009, we find a negative impact of climate change on economic growth. Our results show that a 1°C increase in temperature reduces gross domestic product (GDP) growth by 0.67 percentage point. Evidence from sensitivity analysis shows the two largest economies in the Sub-Saharan Africa (Nigeria and South Africa) play a significant role in ameliorating the negative economic impact of climate change in the region. In addition to impact on Africa, this article provides estimates of the impact of climate change on GDP growth of these 34 countries, which can be valuable in appraising national adaptation plans.We do not find evidence that average long-run temperature changes affect long-run economic growth as measured by 5 year averages.

description: Over the past decade, large-scale land acquisition in Africa has become quite intense, especially in DRC, Ethiopia, Madagascar, Mozambique, Sudan, Tanzania and Zambia. While African countries are motivated by the need to transform the agricultural sector and diversify their economies, the urge to meet the needs of future food and biofuel security, among others, underpins foreign interest. This divergence of interest makes the realisation of the prospective benefits elusive in Africa. Maximsing the benefits of large-scale land acquisition requires bold actions against the following structural impediments: (i) weak land governance and a failure to recognise, protect and properly compensate local communities’ land rights; (ii) lack of country capacity to process and manage large-scale investments; (iii) foreign investors’ proposals that are inconsistent with local and national visions; (iv) resource conflict with negative distributional and gender effects; and (vii) inadequate capacity to assess the social, economic and environmental impact of the project on local communities. This paper suggests a 10-point agenda for maximising the benefits of the land grab in Africa.

A MADS-box transcription factor gene expressed in multicellular appressoria impairs Sclerotinia sclerotiorum virulence in Arabidopsis thaliana and soybean
Creators: name: Godiard, Laurence
Publisher: name: Zenodo
Year: 2023

description: Sclerotinia sclerotiorum is a generalist plant pathogen, responsible for white mold diseases on many cultivated species and is number one disease of irrigated soybean. An improved understanding of the molecular bases of S. sclerotiorum virulence will lead to conceptual advances in plant pathology and renewed opportunities for engineering durable disease resistance in crops. S. sclerotiorum infects also the model plant Arabidopsis thaliana, which we use as a plant model to decipher S. sclerotiorum virulence molecular components at early infection stages. S. sclerotiorum differentiate specific multicellular appressoria, referred to as infection cushions (ICs) that are dedicated to the penetration of host tissues. In order to identify key determinants of IC formation in S. sclerotiorum, we exploited RNAseq in multiple conditions to find 55 S. sclerotiorum genes expressed specifically in ICs. Taxonomic conservation of S. sclerotiorum IC-specific genes was looked in 602 fungal proteomes. Among the ten IC-specific genes with reduced taxonomic distribution, we selected a MADS-box putative transcription factor called SsMADS4 strongly induced in ICs. S. sclerotiorum mutants deleted of or overexpressing SsMADS4 have been generated. Functional analysis of this putative TF supports a role in IC number regulation and host virulence. Further functional studies of SsMADS4 mutants should help to get insight in the interweaving between fungal virulence and IC formation in S. sclerotiorum and other Leotiomycetes.

description: We investigate the consequences of one extra spatial dimension for the stability and energy spectrum of the non-relativistic hydrogen atom with a potential defined by Gauss' law, i.e. proportional to $1/|x|^2$. The additional spatial dimension is considered to be either infinite or curled-up in a circle of radius $R$. In both cases, the energy spectrum is bounded from below for charges smaller than the same critical value and unbounded from below otherwise. As a consequence of compactification, negative energy eigenstates appear: if $R$ is smaller than a quarter of the Bohr radius, the corresponding Hamiltonian possesses an infinite number of bound states with minimal energy extending at least to the ground state of the hydrogen atom.

description: Rating scales are susceptible to response styles that undermine the scale quality. Optimizing a rating scale can tailor it to individuals’ cognitive abilities, thereby preventing the occurrence of response styles related to a suboptimal response format. However, the discrimination ability of individuals in a sample may vary, suggesting that different rating scales may be appropriate for different individuals. This study aims to examine (1) whether response styles can be avoided when individuals are allowed to choose a rating scale and (2) whether the psychometric properties of self-chosen rating scales improve compared to given rating scales. To address these objectives, data from the flourishing scale were used as an illustrative example. MTurk workers from Amazon’s Mechanical Turk platform (N = 7042) completed an eight-item flourishing scale twice: (1) using a randomly assigned four-, six-, or 11-point rating scale, and (2) using a self-chosen rating scale. Applying the restrictive mixed generalized partial credit model (rmGPCM) allowed examination of category use across the conditions. Correlations with external variables were calculated to assess the effects of the rating scales on criterion validity. The results revealed consistent use of self-chosen rating scales, with approximately equal proportions of the three response styles. Ordinary response behavior was observed in 55–58% of individuals, which was an increase of 12–15% compared to assigned rating scales. The self-chosen rating scales also exhibited superior psychometric properties. The implications of these findings are discussed.

description: Terminal oxygen radicals involving p- and d-block atoms are quite common, but s-block compounds with an oxygen radical character remain rare. Here, we report that alkaline-earth metal beryllium atoms react with OF2 to form the oxygen beryllium fluorides OBeF and OBeF2. These species are characterized by matrix-isolation infrared spectroscopy with isotopic substitution and quantum-chemical calculations. The linear molecule OBeF has a 2Π ground state with an oxyl radical character. The 3A2 (C2v) ground state of OBeF2 represents the unusual case of a triplet oxygen atom stabilized by a relatively weak interaction by the Lewis acidic BeF2.

description: A critical analysis of the processes of adopting the various economic development policies revealed that they have been greatly influenced by resource push, environmentally activated and externally imposed factors. Unlike most other developing countries, Nigeria's case presents a puzzle. In spite of the country's abundance of potential natural resources the adoption of several policies and strategies, and the dialec;ics of their adoption, Nigeria's economic development has remained a daunting challenge over the years. Econ.omic performance has not matched the efforts and resources · committed to the process of economic development. Rather than policy prescriptions closing the--gap...heiwn economic perfonnance and the discipline of economics, the gap is getting wider every year. In fact, Nigeria's economy is currently characterised by macroeconomic instability, sectoral imbalances, declining real per capita income, endemic poverty, among others. This puzzle, therefore, poses a serious question to every policy analyst in Nigeria: Why are policies not working in the country? The answer to this question constitutes the rhajor challenge of this paper. In addition, it also aims at analysing the evolution and the dialectics of economic development policies and strategies in Nigeria. To accomplish this task, the rest of this paper is organised into four parts. Following this introduction is Part II which examines the dynamics . and dialectics of economic development policies in Nigeria. Part III analyses the outcomes of development policies. Part IV examines the reasons for policy failures in Nigeria while the policy implications and conclusions of our discussion are contained in Part V.

description: Nigeria is governed by a federal system, hence its fiscal operations also adhere to the same principle, a fact which has serious implications on how the tax system is managed. The country’s tax system is lopsided, and dominated by oil revenue. It is also characterized by unnecessarily complex, distortionary and largely inequitable taxation laws that have limited application in the informal sector that dominates the economy. The primary objective of this paper is to prepare a case study on tax policy reforms in Nigeria, with the specific objectives of examining the main tax reforms in the country; highlighting tax revenue profile and composition; analysing possible distributional impacts on the poor; discussing major problems that could prevent effective tax implementation in the country; and offering suggestions for reforms.

description: We present magneto-optic measurements on two materials that form the recently discovered twist-bend nematic (Ntb) phase. This intriguing state of matter represents a new fluid phase that is orientationally anisotropic in three directions and also exhibits translational order with periodicity several times larger than the molecular size. NTB materials may also spontaneously form a visible, macroscopic stripe texture. We show that the optical stripe texture can be persistently inhibited by a magnetic field, and a 25T external magnetic field depresses the N-Ntb phase transition temperature by almost 1 degree C. We propose a quantitative mechanism to account for this shift and suggest a Helfrich-Hurault-type mechanism for the optical stripe formation.

description: To elucidate the role of low-coordinated sites in the partial methanol oxidation to methyl formate (MeFo), the isothermal reactivity of flat Au(111) and stepped Au(332) in pulsed molecular beam experiments was compared for a broad range of reaction conditions. Low-coordinated step sites were found to enhance MeFo selectivity, especially at low coverage conditions, as found at higher temperatures. The analysis of the transient kinetics provides evidence for the essential role of AuxOy phases for MeFo formation and the complex interplay of different oxygen species for the observed selectivity. Ab initio molecular dynamic simulations yielded microscopic insights in the formation of AuxOy phases on flat and stepped gold surfaces emphasizing the role of low-coordinated sites in their formation. Moreover, associated surface restructuring provides atomic-scale insights which align with the experimentally observed transient kinetics in MeFo formation.

description: Purpose: Careful assessment of the aortic root is paramount to select an appropriate prosthesis for transcatheter aortic valve implantation (TAVI). Relevant information about the aortic root anatomy, such as the aortic annulus diameter, can be extracted from pre-interventional CT. In this work, we investigate a neural network-based approach for segmenting the aortic root as a basis for obtaining these parameters. Methods: To support valve prosthesis selection, geometric measures of the aortic root are extracted from the patient's CT scan using a cascade of convolutional neural networks (CNNs). First, the image is reduced to the aortic root, valve, and left ventricular outflow tract (LVOT); within that subimage, the aortic valve and ascending aorta are segmented; and finally, the region around the aortic annulus. From the segmented annulus region, we infer the annulus orientation using principal component analysis (PCA). The area-derived diameter of the annulus is approximated based on the segmentation of the aortic root and LVOT and the plane orientation resulting from the PCA. Results: The cascade of CNNs was trained using 90 expert-annotated contrast-enhanced CT scans routinely acquired for TAVI planning. Segmentation of the aorta and valve within the region of interest achieved an F1 score of 0.94 on the test set of 36 patients. The area-derived diameter within the annulus region was determined with a mean error below 2 mm between the automatic measurement and the diameter derived from annotations. The calculated diameters and resulting errors are comparable to published results of alternative approaches. Conclusions: The cascaded neural network approach enabled the assessment of the aortic root with a relatively small training set. The processing time amounts to 30 s per patient, facilitating time-efficient, reproducible measurements. An extended training data set, including different levels of calcification or special cases (e.g., pre-implanted valves), could further improve this method's applicability and robustness.

description: Rapid digitalization and an aging population are leading to an increasingly prominent age-based digital divide among the world’s elderly population. This study focuses on China, one of the most rapidly aging and digitalizing countries in the world. Employing a mixed-method approach, this research examines how elderly individuals experience the digital transformation and the associated digital divide. The findings suggest that the elderly interviewees encounter multiple barriers to learning and using digital technologies, which highlights the significant role of social support and networks in facilitating their adaptation to the digital society and lifestyle. Attitudes toward digital engagement and digitalization vary greatly among the elderly, ranging from being optimistic to feeling left behind and having multiple concerns. Our findings further reveal that the Chinese government has implemented numerous digital apps tailored to the demands of the elderly and provided training opportunities to bridge the gray digital divide. This emphasizes the responsiveness and adaptiveness of Chinese authorities in addressing pressing societal issues. However, we identify a gap in digital outreach, as most elderly interviewees have limited awareness of government digital inclusion policies and programs. This article contributes to digital divide research and offers practical implications for countries grappling with the gray digital divide.

description: We have measured circularly polarized photoluminescence in monolayer MoSe2 under perpendicular magnetic fields up to 10 T. At low doping densities, the neutral and charged excitons shift linearly with field strength at a rate of $\mp$ 0.12 meV/T for emission arising, respectively, from the K and K' valleys. The opposite sign for emission from different valleys demonstrates lifting of the valley degeneracy. The magnitude of the Zeeman shift agrees with predicted magnetic moments for carriers in the conduction and valence bands. The relative intensity of neutral and charged exciton emission is modified by the magnetic field, reflecting the creation of field-induced valley polarization. At high doping levels, the Zeeman shift of the charged exciton increases to $\mp$ 0.18 meV/T. This enhancement is attributed to many-body effects on the binding energy of the charged excitons.
