description: We report the characterization of correlated photon pairs generated in dispersion-engineered silicon slow-light photonic crystal waveguides pumped by picosecond pulses. We found that taking advantage of the 15 nm flat-band slow-light window (vg ~ c/30) the bandwidth for correlated photon-pair generation in 96 and 196 \mum long waveguides was at least 11.2 nm; while a 396 \mum long waveguide reduced the bandwidth to 8 nm (only half of the slow-light bandwidth due to the increased impact of phase matching in a longer waveguide). The key metrics for a photon-pair source: coincidence to accidental ratio (CAR) and pair brightness were measured to be a maximum 33 at a pair generation rate of 0.004 pair per pulse in a 196 \mum long waveguide. Within the measurement errors the maximum CAR achieved in 96, 196 and 396 \mum long waveguides is constant. The noise analysis shows that detector dark counts, leaked pump light, linear and nonlinear losses, multiple pair generation and detector jitter are the limiting factors to the CAR performance of the sources.

Myd88 is required for haematopoietic development in Drosophila
Creators: name: Sohail, Huma
Publisher: name: The Australian National University
Year: 2023

description: MYD88 is an adaptor protein that has been characterised to transmit immune signals from activated Toll-like receptor (TLR) or Interleukin-1 (IL-1) receptor to the NF-kB pathway. The Toll pathway was first identified in Drosophila, which led to the subsequent discovery of the analogous Toll-like Receptor (TLR) pathway in mammals. Somatic activating point mutations in MYD88 cause a number of haematological malignancies, which include Activated B Cell-Diffuse Large B Cell Lymphoma (ABC-DLBCL), driven in part through increased NF-kB signalling. Although the role of Toll and TLR pathways in modulating response to infectious disease is well-documented, functions in normal haematopoietic development have not been fully elucidated. Therefore, we employed Drosophila to study the function of the conserved Myd88 orthologue in the development of the haematopoietic compartment - the lymph gland. Surprisingly, given activation of mammalian MYD88 drives lymphoma, we demonstrate that haemocyte-specific Myd88 knockdown drives lymph gland overgrowth. Transcriptome profiling of Myd88-depleted lymph glands revealed dysregulation of major developmental signalling pathways, including activation of Ras/MAPK and Wnt/beta-catenin. Furthermore, our genetic interaction studies demonstrated that overgrowth caused by Myd88 knockdown requires beta-catenin activity. Myd88 is, therefore, an essential inhibitor of haematopoietic compartment growth mediated by beta-catenin. Together, these findings not only reveal new roles for Myd88 signalling in development, but also suggest novel mechanisms for the regulation of beta-catenin in haematopoiesis. Future studies investigating potential roles for MYD88 in the regulation of Wnt pathway in mammalian development, may provide insight into novel mechanisms for Wnt-driven cancer.

Cumulants of the q-semicircular law, Tutte polynomials, and heaps
Creators: name: Josuat-Vergès, Matthieu
Publisher: name: arXiv
Year: 2012
Subjects: subject: Combinatorics (math.CO)
subject: FOS: Mathematics

description: The q-semicircular distribution is a probability law that interpolates between the Gaussian law and the semicircular law. There is a combinatorial interpretation of its moments in terms of matchings where q follows the number of crossings, whereas for the free cumulants one has to restrict the enumeration to connected matchings. The purpose of this article is to describe combinatorial properties of the classical cumulants. We show that like the free cumulants, they are obtained by an enumeration of connected matchings, the weight being now an evaluation of the Tutte polynomial of a so-called crossing graph. The case q=0 of these cumulants was studied by Lassalle using symmetric functions and hypergeometric series. We show that the underlying combinatorics is explained through the theory of heaps, which is Viennot's geometric interpretation of the Cartier-Foata monoid. This method also gives results for the classical cumulants of the free Poisson law.

description: We discuss several properties of static, spherically symmetric wormholes with particular emphasis on the behavior of causal geodesics and the propagation of linear fields. We show there always exist null geodesics which are trapped in a region close to the throat. Depending upon the detailed structure of the wormhole geometry, these trapped geodesics can be stable, unlike the case of the Schwarzschild black hole. We also show that test scalar fields propagating on such wormholes are stable. However, when a mixture of ghost and Klein-Gordon scalar fields is used as a source of the Einstein equations we prove that the resulting static, spherically symmetric wormhole configurations are linearly unstable.

description: (Abridged) While the Swift satellite is primarily designed to study gamma-ray bursts, its ultraviolet and optical imaging and spectroscopy capabilities are also being used for a variety of scientific programs. In this study, we use the UV/Optical Telescope (UVOT) instrument aboard Swift to discover 0.560ks exposure time, achieving a limiting magnitude of u<24.5, in the Chandra Deep Field South (CDF-S). Applying UVOT near-ultraviolet color selection, we select 50 UV-dropouts from this UVOT CDF-S data. We match the selected sources with available multiwavelength data from GOODS-South, MUSYC, and COMBO-17 to characterize the spectral energy distributions for these galaxies and determine stellar masses, star formation rates (SFRs), and dust attenuations. We compare these properties for LBGs selected in this paper versus z~3 LBGs and other CDF-S galaxies in the same redshift range (0.5

description: We perform extensive molecular dynamics simulations of dense liquids composed of bidisperse dimer- and ellipse-shaped particles in 2D that interact via repulsive contact forces. We measure the structural relaxation times obtained from the long-time decay of the self-part of the intermediate scattering function for the translational and rotational degrees of freedom (DOF) as a function of packing fraction ϕ, temperature T, and aspect ratio α. We are able to collapse the ϕand T-dependent structural relaxation times for disks, and dimers and ellipses over a wide range of α, onto a universal scaling function {\cal F}_{\pm}(|ϕ-ϕ_0|,T,α), which is similar to that employed in previous studies of dense liquids composed of purely repulsive spherical particles in 3D. {\cal F_{\pm}} for both the translational and rotational DOF are characterized by the α-dependent scaling exponents μand δand packing fraction ϕ_0(α) that signals the crossover in the scaling form {\cal F}_{\pm} from hard-particle dynamics to super-Arrhenius behavior for each aspect ratio. We find that the fragility at ϕ_0, m(ϕ_0), decreases monotonically with increasing aspect ratio for both ellipses and dimers. Moreover, the results for the slow dynamics of dense liquids composed of dimer- and ellipse-shaped particles are qualitatively the same, despite the fact that zero-temperature static packings of dimers are isostatic, while static packings of ellipses are hypostatic.

description: Tropical sexually transmitted infections. Summary of the SFMTSI Scientific Day of November 9, 2023 Taking an interest in tropical sexually transmitted infections (STIs) today means anticipating the risks of tomorrow. The arrival of monkeypox in the summer of 2022 has confirmed the risk of travelers exporting STIs as tropical as the original HIV/AIDS infection. Some hazards are already well identified. Classic STIs are still numerous in the tropics, and there is no sign that they are decreasing. Antibiotic resistance is on the increase for gonococcus, and already well established for Mycoplasma genitalium, and still to come (uncertain) for syphilis. Some tropical viruses (Zika, Ebola, monkeypox) can also be sexually transmitted, sometimes months after recovery (Ebola). In this context, the extension of PrEP indications to migrants, and its dissemination in Africa, is worth discussing beyond traditional circles. Infections sexuellement transmissibles tropicales. Synthèse de la Journée scientifique de la SFMTSI du 9 novembre 2023 S’intéresser aujourd’hui aux infections sexuellement transmissibles (IST) tropicales, c’est appréhender les risques de demain. L’arrivée de la variole du singe, à l’été 2022, a confirmé le risque d’exportation, par les voyageurs, d’IST aussi tropicales que l’infection VIH/sida a pu l’être à son origine. Certains dangers sont déjà bien identifiés. Les IST classiques restent nombreuses sous les tropiques et rien n’indique qu’elles sont en décroissance. La résistance aux antibiotiques est croissante pour le gonocoque, déjà bien installée pour Mycoplasma genitalium, et en devenir (incertain) pour la syphilis. Certaines viroses tropicales (Zika, Ebola, variole du singe) peuvent aussi être sexuellement transmissibles, et parfois des mois après la guérison (Ebola). Dans ce contexte, l’élargissement des indications de la PrEP aux migrants, et sa diffusion en Afrique méritent d’être discutés au-delà des cercles traditionnels.

description: We have been developing public experiments with tables and in public spaces under the frame of citizen science participatory practices and with several games and social dilemmas. Also during these years, the understanding of social systems and more particularly social interactions is being revolutionized with the internet and of extensive use of mobile phones and messaging platforms. We here want to share first attempts to explore the possibility to use Telegram chatbot to further explore human behaviour. We first show a first experiment developed in the context of a street arts festival. Over 200 participants were responding to questions provided by a hundred young students of a small town (16 years old on average). Questions were related to social, political, and philosophical concerns, matters and doubts that each student had individually and anonymously raised after a series of 1 hour workshops. Answers were always binary and have been analyzed to measure opinion heterogeneity and clusters of opinion profiles in a three months recording. We present statistical physics and complex systems theory analysis methods that enrich the long-standing tradition of plain surveys in sociology and psychology. The experimental setup allows long time recording of large data sets with the ethical agreement of the human subjects participating, and with large freedom in the design of the experiment and therefore, the research question. We will finally also share details of the construction of a more sophisticated chatbot called Coactuem per la Salut Mental / CoAct for Mental Health. We will be able to show preliminary first results from this upscaled experiment that narrows down the scope to social support networks in mental health. The chatbot will be launched in September 2021.

description: Atrial tuberculosis concomitant with pulmonary localization in an HIV-immunosuppressed patient, in Bamako, Mali Introduction/Rationale. Tuberculosis remains a major public health issue. It is an opportunistic pathology, very common in HIV-immunocompromised persons, classifying it at the WHO stage 4. Atrial tuberculosis remains a rare and under-diagnosed clinical form. We report here a case of atrial tuberculosis concomitant with pulmonary localization in an HIV-immunosuppressed person on triple antiretroviral therapy aged 32 years hospitalized in Bamako (Mali) to discuss the diagnostic and therapeutic difficulties posed by this rare localization. Description of the case. The patient had a chronic productive cough, otalgia and right chronic purulent otorrhea. The search for acid-resistant bacilli was positive for direct examination in gastric casing fluid and swabbing of the atrial pus, confirming the diagnosis of tuberculosis. Anti-tuberculosis treatment instituted for 6 months associated with adjuvants resulted in complete healing of the patient. Discussion/conclusion. Although rare, atrial localization must be actively sought. Etiological treatment must be instituted upon confirmation of the diagnosis to avoid complications and sequelae. Tuberculose auriculaire concomitante à une localisation pulmonaire chez un patient immunodéprimé par le VIH, à Bamako, Mali Introduction/Justification. La tuberculose demeure un problème de santé publique majeur. Elle constitue une pathologie opportuniste, très fréquente chez les immunodéprimés par le VIH, classant le sida en stade clinique IV de l’OMS en cas de localisations extra pulmonaires. La tuberculose auriculaire reste une forme clinique rare et sous-diagnostiquée. Nous rapportons un cas de tuberculose auriculaire concomitante à une localisation pulmonaire chez un immunodéprimé par le VIH de 32 ans, hospitalisé à Bamako (Mali) afin de discuter des difficultés diagnostiques et thérapeutiques posées par cette localisation rare. Description du cas. Le patient présentait une toux productive chronique, une otalgie et une otorrhée purulente chronique droite. La recherche de bacilles acido-alcoolo-résistants était positive à l’examen direct dans le liquide de tubage gastrique et l’écouvillonnage du pus auriculaire. Un traitement antituberculeux institué pendant 6 mois, associé aux adjuvants, a conduit à la guérison complète du patient. Discussion/conclusion. La localisation auriculaire, bien que rare, doit être activement recherchée. Un traitement étiologique doit être institué pour éviter les complications et les séquelles.

description: Disease spreading through human travel networks has been a topic of great interest in recent years, as witnessed during outbreaks of influenza A (H1N1) or SARS pandemics. One way to stop spreading over the airline network are travel restrictions for major airports or network hubs based on the total number of passengers of an airport. Here, we test alternative strategies using edge removal, cancelling targeted flight connections rather than restricting traffic for network hubs, for controlling spreading over the airline network. We employ a SEIR metapopulation model that takes into account the population of cities, simulates infection within cities and across the network of the top 500 airports, and tests different flight cancellation methods for limiting the course of infection. The time required to spread an infection globally, as simulated by a stochastic global spreading model was used to rank the candidate control strategies. The model includes both local spreading dynamics at the level of populations and long-range connectivity obtained from real global airline travel data. Simulated spreading in this network showed that spreading infected 37% less individuals after cancelling a quarter of flight connections between cities, as selected by betweenness centrality. The alternative strategy of closing down whole airports causing the same number of cancelled connections only reduced infections by 18%. In conclusion, selecting highly ranked single connections between cities for cancellation was more effective, resulting in fewer individuals infected with influenza, compared to shutting down whole airports. It is also a more efficient strategy, affecting fewer passengers while producing the same reduction in infections. The network of connections between the top 500 airports is available under the resources link on our website http://www.biological-networks.org.

It establishes the spectrum properties and regularity estimates of the associated Stokes operators, the local well-posedness of the strong solution and global existence of weak solutions for initial boundary value problems for such systems. Furthermore, the vanishing $α$ limit to a weak solution of the corresponding initial-boundary value problem of the Navier-Stokes system is proved and a rate of convergence is shown for the strong solution.

Échec de la campagne d’éradication de la poliomyélite avec le vaccin oral : on ne vaccine pas sans adhésion

Year: 2023

description: Failure of poliomyelitis eradication campaign with oral vaccine: there’s no vaccination without adherence Thirty-five years after its launch, the Global Polio Eradication Initiative has yet to reach its original goal of 2000. Not only is the wild type 1 polio virus still endemic in two countries, but a new outbreak due to viruses derived from the live attenuated virus used for the oral vaccine has been spreading since 2016. The National Immunization Days (NID), during which teams go door-to-door and attract children to be vaccinated, have provoked violent opposition particularly in Northern Nigeria and in the area of India, Pakistan, Afghanistan. In both regions, the same rumor has developed that the vaccine contains sterilizing products, in order to limit the Muslim population. The organizers of the campaign multiplied in vain the NIDs to overcome the resistance, but pockets of insufficiently vaccinated population have persisted. This has allowed the wild virus to remain endemic and the new outbreak of vaccine-derived viruses to progress. We can wonder what the campaign would have become if its organizers had taken the time to reflect and reorient their strategy to rely on the routine vaccination of the Expanded Program on Immunization that does not arouse such opposition. Échec de la campagne d’éradication de la poliomyélite avec le vaccin oral : on ne vaccine pas sans adhésion Trente-cinq ans après son lancement, l’Initiative mondiale pour l’éradication de la poliomyélite n’a toujours pas atteint son but, originellement fixé à l’an 2000. Non seulement le virus sauvage de type 1 de la poliomyélite est toujours endémique dans deux pays, mais une nouvelle épidémie due à des virus dérivés du virus vivant atténué utilisé pour le vaccin oral se propage depuis 2016. Les Journées nationales de vaccination (JNV), au cours desquelles des équipes font du porte-à-porte, tout en vaccinant parfois également dans les rues, ont suscité de violentes oppositions particulièrement dans le nord du Nigéria et dans la zone Inde, Pakistan, Afghanistan. Dans les deux régions, la même rumeur s’est développée selon laquelle le vaccin contiendrait des produits stérilisants, pour limiter la population musulmane. Les organisateurs de la campagne ont multiplié en vain les JNV pensant finir par venir à bout des résistances, mais celles-ci ont laissé des poches de population insuffisamment vaccinée, ce qui a permis au virus sauvage de demeurer endémique et à la nouvelle épidémie de virus dérivés du vaccin de progresser. Nous pouvons nous poser la question de ce que la campagne serait devenue si ses organisateurs avaient pris le temps de la réflexion et réorienté leur stratégie pour s’appuyer sur la vaccination de routine du Programme élargi de vaccination, qui ne suscite pas de telles oppositions.

description: We study step flow growth of epitaxial graphene on 6H-SiC using a one dimensional kinetic Monte Carlo model. The model parameters are effective energy barriers for the nucleation and propagation of graphene at the SiC steps. When the model is applied to graphene growth on vicinal surfaces, a strip width distribution is used to characterize the surface morphology. Additional kinetic processes are included to study graphene growth on SiC nano-facets. Our main result is that the original nano-facet is fractured into several nano-facets during graphene growth. This phenomenon is characterized by the angle at which the fractured nano-facet is oriented with respect to the basal plane. The distribution of this angle across the surface is found to be related to the strip width distribution for vicinal surfaces. As the terrace propagation barrier decreases, the fracture angle distribution changes continously from two-sided Gaussian to one-sided power-law. Using this distribution, it will be possible to extract energy barriers from experiments and interpret the growth morphology quantitatively.

description: We present a search for neutrino-induced events containing a single, exclusive photon using data from the NOMAD experiment at the CERN SPS where the average energy of the neutrino flux is $\simeq 25$ GeV. The search is motivated by an excess of electron-like events in the 200--475 MeV energy region as reported by the MiniBOONE experiment. In NOMAD, photons are identified via their conversion to $e^+e^-$ in an active target embedded in a magnetic field. The background to the single photon signal is dominated by the asymmetric decay of neutral pions produced either in a coherent neutrino-nucleus interaction, or in a neutrino-nucleon neutral current deep inelastic scattering, or in an interaction occurring outside the fiducial volume. All three backgrounds are determined {\it in situ} using control data samples prior to opening the `signal-box'. In the signal region, we observe {\bf 155} events with a predicted background of {\bf 129.2 $\pm$ 8.5 $\pm$ 3.3}. We interpret this as null evidence for excess of single photon events, and set a limit. Assuming that the hypothetical single photon has a momentum distribution similar to that of a photon from the coherent $π^0$ decay, the measurement yields an upper limit on single photon events, {\boldmath $< 4.0 \times 10^{-4}$} per \nm\ charged current event. Narrowing the search to events where the photon is approximately collinear with the incident neutrino, we observe {\bf 78} events with a predicted background of {\bf 76.6 $\pm$ 4.9 $\pm$ 1.9} yielding a more stringent upper limit, {\boldmath $< 1.6 \times 10^{-4}$} per \nm\ charged current event.

description: This paper presents our perspective on the reparability of screen-based mobile electronic devices, with a first focus on smartphones. Repair is an effective way to increase the lifetime of electronics, saving material resources and contributing to a lower environmental burden. Transparency regarding the reparability of products can drive the market towards more sustainable designs. Based on previous work and new evaluation tests, and together with recent advances in the state-of-the-art literature, we have further refined our method for assessing the repair potential of smartphones for informal repairers with no-to-low experience. The method consists of a heuristic assessment and a disassembly protocol tracking the disassembly process. The method is used to provide a numerical score for eight criteria, selected by their relevance to capture important information for lay people repairing their own device when replacing only a malfunctioning part. The criteria are: (1) Path of entry; (2) Accessibility of critical components; (3) Availability of spare parts; (4) Availability of information; (5) Type of tools needed; (6) Endorsed repair options; (7) Visual cues and (8) Health and safety risk. To reduce the complexity of the assessment while preserving comparability, we only take the disassembly of those components into account which are critical to functionality and have an increased chance of malfunctioning, the so-called ‘critical components’. For smartphones, the critical components are the display assembly and the battery. Rather than performing a full disassembly, in this approach only the disassembly paths down to the critical components are tracked. To calibrate the method, a set of known outlier devices are assessed and placed at each end of the spectrum. Two flagship smartphone devices are evaluated to show the methods’ scoring of representative products in the current smartphone market. This paper will discuss the results of the assessment, observe reparability trends in the current smartphone market, and suggest options for further research.

description: The ‘food system’ urgently needs a sustainable transformation. Two major challenges have to be solved: the food system has to provide food security with healthy, accessible, affordable, safe and diverse food for all, and it has to do so within the safe operating space of the planetary boundaries, where the pollution from reactive nitrogen turned out to be the largest bottleneck. Here we argue that thinking strategically about how to balance nitrogen flows throughout the food system will make current food systems more resilient and robust. Looking from a material and a governance perspective on the food system, we highlight major nitrogen losses and policy blind spots originating from a compartmentalization of food system spheres. We conclude that a participatory and integrated approach to manage nitrogen flows throughout the food system is necessary to stay within regional and global nitrogen boundaries, and will additionally provide synergies with a sustainable and healthy diet for all. © 2020 The Authors

description: We discuss homogeneous and isotropic cosmological models driven by SU(2) gauge fields in the framework of Einstein gravity. There exists a Yang-Mills field configuration, parametrized by a single scalar function, which consists of parallel electric and magnetic fields and has the stress tensor mimicking an homogeneous and isotropic fluid. The unique SU(2) gauge theory with spontaneous symmetry breaking sharing the same property is the Yang-Mills coupled to the complex doublet Higgs, this exists only in the case of the closed universe. This model contains an intrinsic mechanism for inflation due to the Higgs potential. Our second goal is to show that a successful inflation can be achieved also within the pure Yang-Mills theory adding an appropriate theta-term.

description: The dilaton is predicted in various extensions of the standard model containing sectors with an approximate spontaneously-broken conformal invariance. As a Goldstone boson of a spontaneously broken symmetry, the dilaton can naturally be one of the lightest new physics particles, and therefore may be the first new physics imprint observed in collider experiments. In particular, it can arise in composite Higgs models which are often assumed to have approximate conformal invariance in the UV. The dilaton is then a composite state, generated by the same sector that produces the Higgs. We continue the exploration of composite dilaton signatures at the LHC, using the latest experimental data and analysing the future detection prospects. We elaborate on the connection of the dilaton properties with the properties of the Higgs potential, clarifying in particular the relation between the scale relevant for electroweak fine tuning and the scale controlling the dilaton couplings. This relation is then used to derive the experimental sensitivity to the dilaton in natural composite Higgs scenarios, which reaches ~3 TeV in dilaton mass for generic parameter choices. At the same time, we show that dilaton searches are a complementary direction to probe Higgs boson compositeness, with the sensitivity comparable or exceeding that of Higgs coupling measurements.

description: We study coupled unitary Virasoro minimal models in the large rank ($m \rightarrow \infty$) limit. In large $m$ perturbation theory, we find two non-trivial IR fixed points which exhibit irrational coefficients in several anomalous dimensions and the central charge. For $N>4$ copies, we show that the IR theory breaks all possible currents that would otherwise enhance the Virasoro algebra, up to spin 10. This provides strong evidence that the IR fixed points are examples of compact, unitary, irrational CFTs with the minimal amount of chiral symmetry. We also analyze anomalous dimension matrices for a family of degenerate operators with increasing spin. These display further evidence of irrationality and begin to reveal the form of the leading quantum Regge trajectory.

description: Objective: Increased health literacy (HL) improves the management of chronic diseases. Data on the HL levels of adolescents with asthma are limited. In this study, we aimed to investigate the HL levels of adolescents with asthma and the effect of HL levels on asthma control. Methods: Our research included 81 adolescents with asthma and 47 age and sex-matched controls. The validated version of the European Health Literacy Survey Questionnaire (HLS-EU-Q16) was utilized to estimate the participants’ health literacy levels. In addition, the Asthma Control Test (ACT) was used to determine the degree of asthma control. Results: No significant difference between the asthmatic adolescents (n = 45, 55.6%) and the control group (n = 28, 59.6%) has been established in terms of the number of participants who were considered to have adequate HL (p = 0.658). The difference between the patient and control groups in health care, disease prevention, health promotion, and overall HL scores was determined non-significant. According to the ACT scores, the overall median HL score was significantly higher in patients with controlled asthma {34.4 (14.6:50)} than in those with uncontrolled asthma {32.3 (16.7:48.9)} (p = 0.037). It was determined that there was a difference in the distribution of controlled asthma, uncontrolled asthma, and controls in HL subgroups (poor, problematic-limited, sufficient, and perfect HL) (p = 0.002). Conclusion: The level of HL is associated with asthma control. A significant proportion of asthmatic adolescents who participated in our research displayed low HL scores. Further studies should be conducted to increase the HL levels of adolescents to achieve better asthma control.

description: The form factors and the coupling constants in the $B^{\ast}B^{\ast}ρ$ vertex are evaluated in the framework of three-point QCD sum rules. The correlation functions responsible for the form factors are evaluated considering contributions of both $B^{\ast}$ and $ρ$ mesons as off-shell states. The obtained numerical results for the coupling constants are in agreement with light-cone QCD sum rules calculations.
