description: Dans un contexte de perte de biodiversité, l'étude de la connectivité et des diversités génétique et spécifique des écosystèmes fragmentés apparaît essentielle pour comprendre et prédire leur capacité et leur probabilité de résilience. La mission MAD avait pour but d'estimer les diversités spécifiques et génétiques des populations marines de la région Nord-Est et Nord-Ouest de Madagascar. Cette région est très riche en diversité spécifique marine et présente un fort endémisme. La côte Nord-Ouest est adjacente des eaux des Parcs naturels marins des Glorieuses et de Mayotte et la côte Nord-Est bien que très riche, reste encore peu explorée. Pour ce faire, nous avons choisi quatre peuplements du compartiment benthique : les coraux Scléractiniaires, les bénitiers, les holothuries et les macroalgues, dont les fonctions diffèrent au sein de l'écosystème et qui représentent des indicateurs de la santé des milieux coralliens. Le présent projet répondra à cinq objectifs principaux: (1) dresser un inventaire des espèces de bénitiers, des coraux, d'holothuries et de macroalgues, en particulier avec des collections de tissus pour des analyses génétiques (taxonomie moléculaire et génétique des populations) ; (2) analyser la diversité cryptique d'espèces de coraux (notamment espèces du genre Pocillopora), de bénitiers et de macroalgues ; (3) implémenter les collections de référence pour les coraux et pour les macroalgues et enrichir les collections nationales, internationales, de l'IRD et de l'Université de La Réunion ; (4) compléter l'échantillonnage régional et Indo-Pacifique pour certaines espèces de coraux, de bénitiers, d'holothuries et de macroalgues; (5) évaluer les diversités et structures génétiques multi-échelles et estimer la connectivité entre les populations de certaines espèces de coraux, de bénitiers, d'holothuries et de macroalgues récoltées sur les différentes îles du Sud-Ouest de l'océan Indien dans le cadre d'autres programmes.
title: Teaching Orthodontic Emergencies Using The "Flipped Classroom" Method Of Teaching - A Mixed Methods Randomised Controlled Trial
Creators: name: Isherwood, GA
Publisher: name: University of Liverpool Repository
Year: 2019

description: Introduction: The General Dental Council requires newly graduated dentists are competent when managing orthodontic emergencies. Undergraduate students typically receive limited exposure to clinical orthodontics, with the ideal management of these scenarios largely delivered through conventional lectures. The flipped classroom method of teaching involves knowledge being acquired in students’ own time, with class time instead focussing on construction of meaning. Methods: 61 undergraduate dental students were randomised into either a flipped or conventional group. The conventional group (n=30) attended a lecture describing the management of six common emergencies. The flipped group (n=31) were given access to six videos via a virtual learning environment and later completed practical tasks related to the material. Both groups completed a SBA assessment. Perceptions of flipped classroom teaching were explored via focus groups. Results: For questions on orthodontic emergencies, the conventional group had a mean exam result of 70.5% (S.D. 8.0%) compared with the flipped group result of 72.8% (S.D. 12.9%). There was no significant difference between the groups (p=0.532). For regular orthodontic questions the conventional group had a mean exam result of 64.8% (S.D. 19.9%) compared with 78.3% (S.D. 21.7%). There was no significant difference between the groups (p=0.083). Thematic analysis identified the following themes: ways in which videos encourages more effective learning, improved engagement, awareness of learning needs and proposed teaching / curriculum changes. The overarching theme was facilitating an experiential learning cycle using flipped classroom teaching. Conclusions: The flipped classroom method of teaching resulted in comparable exam performance and improved levels of satisfaction.

description: La campagne MAD-Ridge a pour chantier un mont sous-marin de la zone de hauts fonds située entre le sud de l'île de Madagascar et 29°S, dans le sud-ouest de l'Océan Indien. La circulation océanique dans ce secteur est extrêmement dynamique (sous l'influence du Courant Est Madagascar et de sa rétroflexion) et connait une activité tourbillonnaire mésoéchelle importante. La topographie accidentée et les nombreux hauts-fonds sur cette portion de la dorsale de Madagascar interagissent avec les courants océaniques, contribuant probablement à une production biologique importante qui se propage jusqu'aux niveaux trophiques supérieurs. En effet, la zone est classée parmi les aires marines d'importance écologique et biologique (EBSA), notamment parce qu'elle abrite une importante diversité de grands poissons pélagiques exploités par les pêcheries, qu'elle présente des lieux d'étape pour les mammifères marins et qu'elle est répertoriée comme aire de nourrissage pour de nombreuses espèces d'oiseaux marins. Le projet MAD-Ridge propose une étude intégrée et originale de l'effet de la bathymétrie sur la courantologie locale et les dynamiques physicochimiques autour d'un mont sous-marin culminant à 200m sous la surface, et des conséquences sur la productivité des bas niveaux trophiques jusqu'aux niveaux intermédiaires qui constituent les proies des consommateurs supérieurs.La campagne MAD-Ridge s'est déroulée en 2 legs. Cette fiche concerne la première partie de la campagne (8-24 novembre 2016) qui s'est intéressée à la dynamique de moyenne échelle autour du mont sous-marin et ses conséquences sur les réseaux trophiques. Les prélèvements biologiques ont concerné le phytoplancton et le zooplancton pendant ce premier leg. Des enregistrements d'acoustique multifréquence en continu le long du trajet du navire renseignent sur la distribution spatiale et temporelle des organismes mésopélagiques (micronecton) entre la surface et 700m de profondeur. Deux mouillages courantologiques ont également été déployés de part et d'autre du sommet du mont sous-marin en début de campagne (déploiement sur une durée de 2 ans) pour analyser la variabilité temporelle de la circulation océanique et l'influence de la topographie du mont sous-marin.La campagne MAD-Ridge est une opération du programme international IIOE-2 de IOC/UNESCO.

description: In this study, we examine how electronic payment systems (EPS) could help low-income areas get access to traditional banking services. This research looks at how EPS like mobile money, internet banking, and digital wallets help underserved areas get access to banking services. Expanding access to financial services, enhancing efficiency, and getting more people participating in the economy are just a few of the possible benefits of EPS. On the other hand, there are a few negatives, including as cybersecurity risks, poor infrastructure, and low levels of digital literacy. It is a global priority to guarantee that all people and companies may get their hands on adequate, affordable, and prompt financial services. A sizable portion of the population in developing countries either does not have access to or has insufficient bank accounts due to factors such as geographical isolation, poverty, and a lack of infrastructure for traditional banking. The growth of electronic payment systems, which link underserved areas to banks online, could be one explanation.

description: A new homogenization approach for the simulation of multi-phase flows in heterogeneous porous media is presented. It is based on the lattice Boltzmann method and combines the grayscale with the multi-component Shan-Chen method. Thus, it mimics fluid-fluid and solid-fluid interactions also within pores that are smaller than the numerical discretization. The model is successfully tested for a broad variety of single- and two-phase flow problems. Additionally, its application to multi-scale and multi-phase flow problems in porous media is demonstrated using the electrolyte filling process of realistic 3D lithium-ion battery electrode microstructures as an example. The new method shows advantages over comparable methods from literature. The interfacial tension and wetting conditions are independent and not affected by the homogenization. Moreover, all physical properties studied here are continuous even across interfaces of porous media. The method is consistent with the original multi-component Shan-Chen method. It is accurate, efficient, easy to implement, and can be applied to many research fields, especially where multi-phase fluid flow occurs in heterogeneous and multi-scale porous media.

Anyonic Topological Order in Twisted Equivariant Differential (TED) K-Theory

description: While the classification of non-interacting crystalline topological insulator phases by equivariant K-theory has become widely accepted, its generalization to anyonic interacting phases -- hence to phases with topologically ordered ground states supporting topological braid quantum gates -- has remained wide open. On the contrary, the success of K-theory with classifying non-interacting phases seems to have tacitly been perceived as precluding a K-theoretic classification of interacting topological order; and instead a mix of other proposals has been explored. However, only K-theory connects closely to the actual physics of valence electrons; and self-consistency demands that any other proposal must connect to K-theory.
 Here we provide a detailed argument for the classification of symmetry protected/enhanced su(2)-anyonic topological order, specifically in interacting 2d semi-metals, by the twisted equivariant differential (TED) K-theory of configuration spaces of points in the complement of nodal points inside the crystal's Brillouin torus orbi-orientifold.
 We argue, in particular, that: (1) topological 2d semi-metal phases modulo global mass terms are classified by the flat differential twisted equivariant K-theory of the complement of the nodal points; (2) n-electron interacting phases are classified by the K-theory of configuration spaces of n points in the Brillouin torus; (3) the somewhat neglected twisting of equivariant K-theory by "inner local systems" reflects the effective "fictitious" gauge interaction of Chen, Wilczeck, Witten & Halperin (1989), which turns fermions into anyonic quanta; (4) the induced su(2)-anyonic topological order is reflected in the twisted Chern classes of the interacting valence bundle over configuration space, constituting the hypergeometric integral construction of monodromy braid representations.

title: Iron-based intermetallic hard alloys for wear protection

Publisher: name: TU Clausthal
Year: 2025
Subjects: subject: 620

description: The intermetallic hard alloys, the Tribaloys, were developed in the 1970s on the basis of cobalt and nickel. Both base materials are expensive educts, whereby cobalt in particular is limited in its applicability (e.g. food industry, power plant components) and at the same time the demand in certain branches of industry, e.g. electromobility, is very high. It would therefore be desirable to develop an iron-based intermetallic hard alloy with good wear resistance and good processability through a welding process. Preliminary investigations have shown that the intermetallic Laves phase Fe2Ti is very well suited for use as a hard phase in an iron-based wear-resistant alloy. This publication shows that it is possible to produce a coating with an iron-based, intermetallic alloy using a plasma powder cladding process, which can be applied with low cracking, using a modified alloy concept and an improved process strategy. The influence of the alloying elements on the formation of the microstructure morphology is also considered. In addition, the wear resistance in the Miller test according to ASTM G75 is compared with two commercially available cobalt-based alloys and an iron-titanium alloy. It can be shown that the modification of the alloy composition results in different characteristics of the hard phases. The wear resistance of the newly developed iron-based intermetallic hard alloys is significantly higher in the Miller test according to ASTM G75 compared to the two commercially available alloys. Furthermore, an improvement in the wear resistance of the newly modified alloys was achieved compared to the iron-titanium alloy already investigated.

description: The aim of this study was to investigate to what extent psychological factors are related to pain levels prior to non-invasive treatment in patients with osteoarthritis of the first carpometacarpal joint. We included patients (n = 255) at the start of non-invasive treatment for osteoarthritis of the first carpometacarpal joint who completed the Michigan Hand Outcome Questionnaire. Psychological distress, pain catastrophizing behavior and illness perception was measured. X-rays were scored on presence of scaphotrapeziotrapezoid osteoarthritis. We used hierarchical linear regression analysis to determine to what extent pain levels could be explained by patient characteristics, X-ray scores, and psychological factors. Patient characteristics and X-ray scores accounted for only 6% of the variation in pre-treatment pain levels. After adding the psychological factors to our model, 47% of the variance could be explained. Our results show that psychological factors are more strongly related to pain levels prior to non-invasive treatment in patients with osteoarthritis of the first carpometacarpal joint than patient characteristics and X-ray scores, which implies the important role of these factors in the reporting of symptoms. More research is needed to determine whether psychological factors will also affect treatment outcomes for patients treated non-invasively for osteoarthritis of the first carpometacarpal joint.IMPLICATIONS FOR REHABILITATIONPain is the most important complaint for patients with osteoarthritis of the first carpometacarpal joint.Psychological factors are strongly associated with pain levels prior to treatment.Pain catastrophizing behavior appears to be a promising target for complementary treatment in patients with osteoarthritis of the first carpometacarpal joint.

description: Discovering new actively-accreting protoplanets is crucial to answering open questions about planet formation. However, identifying such planets at orbital distances where they are expected to be abundant is extremely challenging, both due to the technical requirements and large distances to star-forming regions. Here we use the kernel phase interferometry (KPI) technique to search for companions around the $\sim$6 and $\sim$8 Myr old Herbig Ae stars MWC 758 and MWC 480. KPI is a data analysis technique which is sensitive to moderate asymmetries, arising from eg. a circumstellar disk or companions with contrasts of up to 6-8 mags, at separations down to and even below the classical Rayleigh diffraction limit ($\sim 1.2λ/ D$). Using the high spectral resolution K-band mode of the SCExAO/CHARIS integral field spectrograph, we search for both excess Br-$γ$ line emission and continuum emission from companions around MWC 480 and MWC 758. We are able to set limits on the presence of rapidly accreting protoplanets and brown dwarfs between 4 and 16 au, well interior to those of previous studies. In Br-$γ$, we set limits on excess line emission equivalent to accretion rates ranging from $10^{-5} M_{j}^{2}.yr^{-1}$ to $10^{-6}M_{j}^{2}.yr^{-1}$. Our achievable contrasts demonstrate that KPI using SCExAO/CHARIS is a promising technique to search for giant accreting protoplanets at smaller separations compared to conventional imaging.

description: Millimeter wave communications require multibeam beamforming in order to utilize wireless channels that suffer from obstructions, path loss, and multi-path effects. Digital multibeam beamforming has maximum degrees of freedom compared to analog phased arrays. However, circuit complexity and power consumption are important constraints for digital multibeam systems. A low-complexity digital computing architecture is proposed for a multiplication-free 32-point linear transform that approximates multiple simultaneous RF beams similar to a discrete Fourier transform (DFT). Arithmetic complexity due to multiplication is reduced from the FFT complexity of $\mathcal{O}(N\: \log N)$ for DFT realizations, down to zero, thus yielding a 46% and 55% reduction in chip area and dynamic power consumption, respectively, for the $N=32$ case considered. The paper describes the proposed 32-point DFT approximation targeting a 1024-beams using a 2D array, and shows the multiplierless approximation and its mapping to a 32-beam sub-system consisting of 5.8 GHz antennas that can be used for generating 1024 digital beams without multiplications. Real-time beam computation is achieved using a Xilinx FPGA at 120 MHz bandwidth per beam. Theoretical beam performance is compared with measured RF patterns from both a fixed-point FFT as well as the proposed multiplier-free algorithm and are in good agreement.

1) la nature de la croûte dans le domaine transitionnel (entre le fit et la limite océan-continent). Pourquoi est-elle déjà amincie ? Est-elle une croûte de 20km purement composée de croûte supérieure ? Il y a-t-il du manteau exhumé ?
2) la position de la croûte océanique. Quand a lieu le contact entre les croûtes océaniques et continentales/transitionnelles le long des zones de fracture de Romanche et São Paulo ? Quelles sont les conséquences sur la subsidence ?
3) la subsidence (par modélisation) ;

description: Monolayer graphene absorbs 2.3 percent of the incident visible light. This 'small' absorption has been used to emphasize the visual transparency of graphene, but it in fact means that multilayer graphene absorbs a sizable fraction of incident light, which causes non-negligible fluorescence. In this paper, we formulate the light emission properties of multilayer graphene composed of tens to hundreds of layers using a transfer matrix method and confirm the method's validity experimentally. We could quantitatively explain the measured contrasts of multilayer graphene on SiO$_2$/Si substrates and found sizable corrections, which cannot be classified as incoherent light emissions, to the reflectance of visible light. The new component originates from coherent emission caused by absorption at each graphene layer. Multilayer graphene thus functions as a partial coherent light source of various wavelengths, and it may have surface-emitting laser applications.

description: In this paper, we show that the 2-sphere does not exhibit symmetry of $L^p$ norms of eigenfunctions of the Laplacian for $p\geq 6$. In other words, there exists a sequence of spherical eigenfunctions $ψ_n$, with eigenvalues $λ_n\to\infty$ as $n\to\infty$, such that the ratio of the $L^p$ norms of the positive and negative parts of the eigenfunctions does not tend to $1$ as $n\to\infty$ when $p\geq 6$. Our proof relies on fundamental properties of the Legendre polynomials and Bessel functions of the first kind.

description: To analyse physical activity of patients during their hospital stay and to explore the relationship between physical activity and barriers to physical activity. This was a secondary analysis of physical activity data for patients admitted to the internal medicine and surgical wards. Physical activity data, collected with a wireless patch sensor, was operationalized as time spent lying, sitting/standing, and walking. Barriers to physical activity included patients’ pain levels, the use of urinary catheters, intravenous tubing, oxygen lines, drains, and level of dependence. Regression analysis explored the relationship between physical activity and barriers to physical activity. Physical activity data were collected in 39 patients (aged 27–88, mean 54 years) during hospital stay. Patients were admitted for a median of 10 d (interquartile range [IQR]: 7–15 d). These patients were lying for a median of 12.1 h (7.6–17.7), sitting/standing 11.8 h (6.3–15.7), and walking 0.1 h (0–0.3) per day. Time lying during the day related to pain levels (β = 0.4 h per unit increase in pain, p < 0.01) and drain use (β = 3.1 h, p < 0.01). Patients spent the most time during the hospital stay lying in bed. Improved pain management and decreased drain use may be worth exploring to increase inpatient physical activity.Implications for rehabilitationContinuous monitoring of physical activity in patients during hospital stay is an important tool for health care professionals to improve multidisciplinary care and rehabilitation.Health care professionals should be aware of the necessity of adequate pain management and critically review the use of drains in order to improve physical activity of patients during hospital stay.Patients need extra support of health care professionals to increase physical activity during consecutive days of their hospital stay.

description: To summarize the available literature related to reliability and validity of the Timed Up and Go in typical adults and children, and individuals diagnosed with the following pathologies: Huntington's disease, stroke, multiple sclerosis, Parkinson's disease, spinal cord injury, Down syndrome, or cerebral palsy. A search was conducted using MeSH terms and keywords through a variety of databases. Data regarding reliability and validity were synthesized. This review included 77 articles. Results were variable depending on the studied population. The Timed Up and Go showed excellent reliability in typical adults, in individuals with cerebral palsy, in individuals with multiple sclerosis, in individuals with Huntington’s disease, individuals with a stroke, and individuals with a spinal cord injury. The TUG demonstrated strong concurrent validity for individuals with stroke and spinal cord injury. Predictive validity data was limited. Based on the literature assessed, the Timed Up and Go is clinically applicable and reliable across multiple populations. The Timed Up and Go has a wide variety of clinical use making it a diverse measure that should be considered when choosing an outcome an activity based outcome measure. However, there are some limitations in the validity of the utilization of the Timed Up and Go to some populations due to a lack of data and/or poor choice of comparison outcome measures when assessing validity. Additional research is needed for young to middle aged adults.IMPLICATIONS FOR REHABILITATIONOutcome measures are a vital component of clinical practice across all populations.The Timed Up and Go is a highly studied outcome measure in the geriatric population, but lacks research of its applicability to other populations.This study was able to highlight the clinical utility of the Timed Up and Go in populations that under utilize this outcome measure.

description: In forensic investigations, emergency medical care, and medical diagnostics, blood group identification is essential. Conventional blood group testing techniques necessitate specific equipment and laboratory conditions, as well as invasive procedures. Biometric information, like fingerprints, has become a new and non-invasive method for predicting genetic and physiological traits in recent years. By investigating the relationship between dermatoglyphic patterns and ABO/Rh blood groups, this studyinvestigates the possibility of using fingerprint analysis to determine an individual's blood group. Machine learning algorithms were trained to recognize patterns and predict blood types with promising accuracy using a dataset that included validated blood group data and fingerprint photos. The findings show a statistically significant correlation between particular blood groups and fingerprint ridge patterns, indicating the potential of this method as an additional or initial screening tool. In order to lessen reliance on blood samples for basic health profile, this research suggests a novel approach to biometric-drivendiagnostics.

description: In this paper, we address the challenge of segmenting global contaminants in large images. The precise delineation of such structures requires ample global context alongside understanding of textural patterns. CNNs specialise in the latter, though their ability to generate global features is limited. Attention measures long range dependencies in images, capturing global context, though at a large computational cost. We propose a gridded attention mechanism to address this limitation, greatly increasing efficiency by processing multi-scale features into smaller tiles. We also enhance the attention mechanism for increased sensitivity to texture orientation, by measuring correlations across features dependent on different orientations, in addition to channel and positional attention. We present results on a new dataset of astronomical images, where the task is segmenting large contaminating dust clouds.

description: Self-interacting dark matter (SIDM) offers the potential to mitigate some of the discrepancies between simulated cold dark matter (CDM) and observed galactic properties. We introduce a physically motivated SIDM model to understand the effects of self interactions on the properties of Milky Way and dwarf galaxy sized haloes. This model consists of dark matter with a nearly degenerate excited state, which allows for both elastic and inelastic scattering. In particular, the model includes a significant probability for particles to up-scatter from the ground state to the excited state. We simulate a suite of zoom-in Milky Way-sized N-body haloes with six models with different scattering cross sections to study the effects of up-scattering in SIDM models. We find that the up-scattering reaction greatly increases the central densities of the main halo through the loss of kinetic energy. However, the physical model still results in significant coring due to the presence of elastic scattering and down-scattering. These effects are not as apparent in the subhalo population compared to the main halo, but the number of subhaloes is reduced compared to CDM.
