INTERFACE DYNAMICS IN CAPILLARY TUBES

description: Capillary forces govern the spreading of liquids on solid walls. These forces play a crucial role in microgravity conditions, impacting liquid transport, liquid location in tanks, and the design of fuel systems for space missions. While Computational Fluid Dynamics (CFD) can provide valuable insights on the fluid behaviour, challenges persist in anticipating the gas-liquid interface dynamics in microgravity, especially for low viscosity and volatile cryogenic fluids such as space propellants. In this study, the accuracy of twophase Volume Of Fluid (VoF) simulations is assessed against a new experimental data-set for a test case involving liquid interface reorientation and capillary rise in a U-shaped divergent tube. The simulations are also compared with an analytical model for the interface motion. The results show that the model and the CFD predict the same macroscopic fluid behaviour. Moreover, the available experimental data allow identifying and tuning the most relevant parameters of the CFD model for a capillary-inertia dominated flow.

description: ArianeGroup is operating an arc heated air plasma generator to test Ceramic Matrix Composites (CMC) and phenolic composites in rocket nozzle and/ or atmospheric re-entry environments. This torch is able to produce an oxidizing flow with temperatures of up to 4000K, heat fluxes of up to 6 or 7 MW/m2 and shear values of about 500 Pa. By its design, the reliability and reproducibility of the torch have been thought to be compatible with the material screening needs. In order to predict the thermal and erosive behaviour of any known material exposed to the extreme conditions of the plasma torch, complex coupled fluid-solid simulations are needed. The analysis logic adopted in this article is incremental and covers the first steps required for this approach. First, CFD calculations of the external plasma jet discharging into the laboratory\'s ambient air are conducted. Two types of configurations are tested: the free jet configuration and an ablation test configuration with a sample holder positioned into the plasma flow. The choices of turbulence models and the assumptions of the jet inlet boundary conditions are discussed by means of a sensitivity study and a comparison with the experimental calibration measurements, available only at a reasonable distance from the potential core along the jet axis. Finally, an estimation of the fluxes in the potential core is conducted via a simplified thermal modelling of the solid sample thermal behaviour, as well as a comparison with temperature measurements from sacrificial tests of CarbonCarbon composites. In further development, the energy balance at the surface of the sample can be completed to take into account the effects of the ablation of the material and thermochemical coupling with the oxidizing environment, always with the aim of constructing a coupled complex simulation.

description: We give an overview of Standard Model Higgs boson studies performed at the CDF and Dzero experiments at the Tevatron proton-antiproton collider. Combining the results of many individual analyses, most of which use the full data set available, an excess with a significance of 3.0 standard deviations with respect to the Standard Model hypothesis is observed at a Higgs boson mass of 125 GeV/$c^2$. At that mass, the combined best-fit cross section is consistent with the Standard Model prediction. Constraints are also placed on the Higgs boson couplings with fermions and electroweak vector bosons and are consistent with the Standard Model predictions within the uncertainties.

Perceptions and experiences of adolescents living with HIV in Malawi
Creators: name: Ammon, Nadine
Publisher: name: Lancaster University
Year: 2023

description: Background: Malawi is among the countries with the highest HIV prevalence worldwide. Adolescents living with HIV face diverse challenges, such as stigma and discrimination, which influence their emotional wellbeing and long-term health, in addition to impacting HIV onward transmission. Furthermore, HIV education, especially the use of fear-based animation and visual aids, as well as the figurative language used for HIV, contributes to how young people perceive and respond to their HIV status, leading to poor health outcomes and decreased wellbeing. Aim: The purpose of this study was to explore descriptions, perceptions, and representations of the HIV-virus among adolescents living with HIV in Malawi, as well as the role that the language used for HIV plays in creating this perception of HIV. It further aimed to examine the impact of these interpretations on their experiences and emotional wellbeing. Methods: This qualitative study employed hermeneutic phenomenology and reflexive thematic analysis, and data were collected through semi-structured in-depth interviews, focus group discussions and drawings, which enhanced the elicitation of participants’ HIV perceptions. Participants were sampled purposively and included 16 adolescents living with HIV, attending a peer support group in a hospital within Lilongwe, and five service providers working at this hospital. Results: The adolescents imagined HIV as personified, harmful creature in their body with functional senses and gender identity. Those negative perceptions originated mainly from the local term used for HIV, HIV-related stigma and discrimination and HIV representations in hospital HIV books, which negatively impacted their emotional wellbeing. However, HIV peer support groups were identified as safe environments for learning about HIV and for debating HIV-related topics, especially in view of the usually required silence and secrecy to prevent stigma. Discussion: The findings enhance the understanding of participants’ lived experiences and perceptions of HIV, and thus may contribute to new methods of holistic health education, tailored for adolescents to improve their emotional wellbeing and attitudes towards HIV through context-specific programmes.

description: In particle image velocimetry (PIV) the measurement signal is contained in the recorded intensity of the particle image pattern superimposed on a variety of noise sources. The signal-to-noise-ratio (SNR) strength governs the resulting PIV cross correlation and ultimately the accuracy and uncertainty of the resulting PIV measurement. Hence we posit that correlation SNR metrics calculated from the correlation plane can be used to quantify the quality of the correlation and the resulting uncertainty of an individual measurement. In this paper we present a framework for evaluating the correlation SNR using a set of different metrics, which in turn are used to develop models for uncertainty estimation. The SNR metrics and corresponding models presented herein are expanded to be applicable to both standard and filtered correlations. In addition, the notion of a valid measurement is redefined with respect to the correlation peak width in order to be consistent with uncertainty quantification principles and distinct from an outlier measurement. Finally the type and significance of the error distribution function is investigated. These advancements lead to robust uncertainty estimation models, which are tested against both synthetic benchmark data as well as actual experimental measurements. For all cases considered here, standard uncertainties are estimated at the 68.5% confidence level while expanded uncertainties are estimated at 95% confidence level. For all cases the resulting calculated coverage factors approximate the expected theoretical values thus demonstrating the applicability of these new models for estimation of uncertainty for individual PIV measurements.

description: Following the "decomposition-and-ensemble" principle, the empirical mode decomposition (EMD)-based modeling framework has been widely used as a promising alternative for nonlinear and nonstationary time series modeling and prediction. The end effect, which occurs during the sifting process of EMD and is apt to distort the decomposed sub-series and hurt the modeling process followed, however, has been ignored in previous studies. Addressing the end effect issue, this study proposes to incorporate end condition methods into EMD-based decomposition and ensemble modeling framework for one- and multi-step ahead time series prediction. Four well-established end condition methods, Mirror method, Coughlin's method, Slope-based method, and Rato's method, are selected, and support vector regression (SVR) is employed as the modeling technique. For the purpose of justification and comparison, well-known NN3 competition data sets are used and four well-established prediction models are selected as benchmarks. The experimental results demonstrated that significant improvement can be achieved by the proposed EMD-based SVR models with end condition methods. The EMD-SBM-SVR model and EMD-Rato-SVR model, in particular, achieved the best prediction performances in terms of goodness of forecast measures and equality of accuracy of competing forecasts test.

description: Multimedia security has been the aim point of considerable research activity because of its wide application area. The major technology to achieve copyright protection, content authentication, access control and multimedia security is watermarking which is the process of embedding data into a multimedia element such as image or audio, this embedded data can later be extracted from, or detected in the embedded element for different purposes. In this work, a blind watermarking algorithm based on SVD and circulant matrices has been presented. Every circulant matrix is associated with a matrix for which the SVD decomposition coincides with the spectral decomposition. This leads to improve the Chandra algorithm [1], our presentation will include a discussion on the data hiding capacity, watermark transparency and robustness against a wide range of common image processing attacks.

description: Accurate time series prediction over long future horizons is challenging and of great interest to both practitioners and academics. As a well-known intelligent algorithm, the standard formulation of Support Vector Regression (SVR) could be taken for multi-step-ahead time series prediction, only relying either on iterated strategy or direct strategy. This study proposes a novel multiple-step-ahead time series prediction approach which employs multiple-output support vector regression (M-SVR) with multiple-input multiple-output (MIMO) prediction strategy. In addition, the rank of three leading prediction strategies with SVR is comparatively examined, providing practical implications on the selection of the prediction strategy for multi-step-ahead forecasting while taking SVR as modeling technique. The proposed approach is validated with the simulated and real datasets. The quantitative and comprehensive assessments are performed on the basis of the prediction accuracy and computational cost. The results indicate that: 1) the M-SVR using MIMO strategy achieves the best accurate forecasts with accredited computational load, 2) the standard SVR using direct strategy achieves the second best accurate forecasts, but with the most expensive computational cost, and 3) the standard SVR using iterated strategy is the worst in terms of prediction accuracy, but with the least computational cost.

description: Iberian pigs must be feed-restricted during the pre-finishing period (premontanera) due to their adipogenic nature. Supplementation with rice husk (a fibrous, abundant and inexpensive byproduct) before finishing may increase satiety, decrease stress and competition, increase animal welfare and might reduce weight gain variability and improve carcass uniformity. This study evaluated the effect of rice husk supplementation on weight gain, carcass composition and hematological traits. Castrate male Iberian pigs were assigned to 3 treatment groups (n=15/group), which, during premontanera, from 10 to 14 months of age, were fed concentrate based diets differing in fibre content, namely Control (C; 5.0%), Medium Fibber (MF; 8.5%) and High Fibber (HF; 12.0%) groups. The MF and HF diets included rice husk (integrated into the concentrate) as a supplemental source of fibre. Rations were isocaloric. Five pigs from each treatment were slaughtered at the end of premontanera, whereas the remaining animals were submitted to free-range acorn-feeding (montanera) and slaughtered at 16 months of age. Body weight (BW) and in vivo ultrasonographic body composition were monitored. A blood sample was collected at the end of premontanera to determine the neutrophil/lymphocyte ratio as a chronic stress index. None of the groups had diarrheic problems, regardless the fibre level. Average daily gain from the 12th to the 14th month of age was greater for the HF group, which also exhibited a more homogeneous growth rate among animals. Moreover, the HF group had the thickest carcass backfat and smallest loin area among the animals slaughtered before montanera. Regarding backfat fatty acid composition premontanera, HF pigs had the lowest C17:0 and C18:3 and the greatest C20:1 percentages, and a trend for greatest MUFA and smallest PUFA values. In conclusion, supplementation with high levels of fibre (12%) from rice husk did not have any negative effect on health, growth or carcass composition.

description: Abstract Background: E-cigarette use is a trend worldwide nowadays with mounting evidence on associated morbidities and mortality. Dentists can modify the smoking behaviors of their patients. This study aimed to explore the knowledge, beliefs, attitude, and practice of E-cigarette use among dental students. Materials and methods: This multinational, cross-sectional, questionnaire-based study recruited undergraduate dental students from 20 dental schools in 11 countries. The outcome variable was current smoking status (non-smoker, E-cigarette user only, tobacco cigarette smoker only, dual user). The explanatory variables were country of residence, sex, age, marital status, and educational level. Multiple linear regression analysis was performed to explore the explanatory variables associated with E-cigarette smoking. Results: Of the 5697 study participants, 5156 (90.8%) had heard about E-cigarette, and social media was the most reported source of information for 33.2% of the participants. For the 5676 current users of E-cigarette and/or tobacco smoking, 4.5% use E-cigarette, and 4.6% were dual users. There were significant associations between knowledge and country (P< 0.05), educational level (B = 0.12; 95% CI: 0.02, 0.21; P = 0.016) and smoking status (P< 0.05). The country of residence (P< 0.05) and smoking status (P< 0.05) were the only statistically significant factors associated with current smoking status. Similarly, there were statistically significant associations between attitude and country (P< 0.05 for one country only compared to the reference) and history of previous E-cigarette exposure (B = -0.52; 95% CI: -0.91, -0.13; P = 0.009). Also, the practice of E-cigarettes was significantly associated with country (P< 0.05 for two countries only compared to the reference) and gender (B = -0.33; 95% CI: -0.52, -0.13; P = 0.001). Conclusion: The knowledge of dental students about E-cigarette was unsatisfactory, yet their beliefs and attitudes were acceptable. Topics about E-cigarette should be implemented in the dental curriculum.

description: In this contribution to the debate I trace distinctive strands in a Scottish approach to social welfare. I make a case that manifestations of a Scottish approach are, however, susceptible to the vagaries of political decisions and directions emanating from Westminster. I go on to argue that, regardless of any political will to assert a Scottish model of social welfare, the ability to do so is fatally compromised within the current political settlement (and indeed within any proposed settlement involving less than independence) by the lack of access to the economic levers required to see through the implications of progressive social policies. This is the academic gist of my case. But there is also another side to it, one that aspires to a better future for Scotland’s children, for their parents and for their communities; a future based upon hope rather than fear.

description: Telescopes with unobstructed pupil are known to deliver clean point spread function (PSF) to their focal plane, in contrast to traditional telescopes with obstructed pupil. Recent progress in the manufacturing aspheric surfaces and mounting accuracy favors unobstructed telescopes over obstructed telescopes for science cases that demand stable and clean PSF over the entire field-of-view. In this paper we compare the image quality of an unobstructed Three-Mirror-Anastigmat (TMA) design with that of an obstructed TMA. Both the designs have the same primary mirror, effective focal length, field-of-view and detector characteristics. We demonstrate using simulated images of faint elliptical galaxies imaged through the two designs, that both the designs can measure morphological parameters with same precision, if the PSF is reconstructed within 12 arc-minutes of the source. We also demonstrate that, the unobstructed design delivers desirable precision even if the PSF is reconstructed 50 arc-minutes away from the source. Therefore the PSF of unobstructed design is uniform over a wider field-of-view compared to an obstructed design. The image quality is given by the 1$σ$ error-bars (68% confidence level) in the fitted values of the axis-ratio and position-angle of the simulated galaxies.

On the operation of X-ray polarimeters with a large field of view

Publisher: name: arXiv

Subjects: subject: Instrumentation and Methods for Astrophysics (astro-ph.IM)

description: The measurement of the linear polarization is one of the hot topics of High Energy Astrophysics. Gas detectors based on photoelectric effect have paved the way for the design of sensitive instruments and mission proposals based on them have been presented in the last few years in the energy range from about 2 keV to a few tens of keV. As well, a number of polarimeters based on Compton scattering are approved or discussed for launch on-board balloons or space satellites at higher energies. These instruments are typically dedicated to pointed observations with narrow field of view telescopes or collimators, but there are also projects aimed at the polarimetry of bright transient sources, like Soft Gamma Repeaters or the prompt emission of Gamma Ray Bursts. Given the erratic appearance of such events in the sky, these polarimeters have a large field of view to catch a reasonable number of them and, as a result, photons may impinge on the detector off-axis. This changes dramatically the response of the instrument to polarization, regardless if photoabsorption or Compton scattering is involved. Instead of the simple cosine square dependency expected for polarized photons which are incident on-axis, the response is never purely cosinusoidal and a systematic modulation appears also for unpolarized radiation. We investigate the origin of these differences and present an analytic treatment which proves that actually such systematic effects are the natural consequence of how current instruments operate. Our analysis provides the expected response of photoelectric or Compton polarimeters to photons impinging with any inclination and state of polarization.

Specifically, the first inequality holds for all finite fields whose characteristic is not three and does not in general hold over characteristic three. The second inequality holds for all finite fields whose characteristic is three and does not in general hold over characteristics other than three. Applications of these inequalities to the computation of capacity upper bounds in network coding are demonstrated.

description: We study the problem of dimension reduction for the three dimensional Gross-Pitaevskii equation (GPE) describing a Bose-Einstein condensate confined in a strongly anisotropic harmonic trap. Since the gas is assumed to be in a strong interaction regime, we have to analyze two combined singular limits: a semi-classical limit in the transport direction and the strong partial confinement limit in the transversal direction. We prove that both limits commute together and we provide convergence rates. The by-products of this work are approximated models in reduced dimension for the GPE, with a priori estimates of the approximation errors.

description: Assessing consumers’ acceptability of traditional pork products (TPP) from local pig breeds is essential to ensure sustainability of regional pork chains. As part of TREASURE project, expectations and hedonic perception of Protected Designation of Origin (PDO) Noir de Bigorre (NB) dry-cured ham produced from pure Gascon breed were assessed. The study was conducted in Toulouse (France) as expanding market for TPP with 124 consumers, regular purchasers of TPP (quota sampling method). Three products were used, described as follows: ‘NB-PDO drycured ham 24 months ripening – local pig breed in extensive system’ (NB24), ‘NB-PDO drycured ham 36 months ripening – local pig breed in extensive system’ (NB36) as innovative TPP to enhance sensory quality, and ‘Iberian ham – 50% Iberian pig’ (IB) as competing product. Following the expectation disconfirmation theory, the sensory test included three phases: blind (tasting without information), expected (product description only: no tasting) and actual liking (tasting with information), assessed using a 9-point scale from 1: extremely dislike to 9: extremely like. Data were submitted to ANOVA (mixed model). Blind hedonic test showed no differences (P>0.05) between products that all displayed high liking score (6.7 to 6.8). Product description strongly influenced expected liking (P<0.001) with higher score for NB36 than NB24 (7.8 vs 7.2, P<0.05) and lowest score for IB (5.2). Hedonic test with information showed higher actual liking for NB36 and NB24, that were similar, than for IB (7.4 and 7.2 vs 5.9, P<0.001). Both NB hams displayed higher actual than blind liking (P<0.05), denoting positive effect of information on acceptability. Actual liking was similar to expected for NB24, indicating fulfilment of hedonic expectations. By contrast, actual liking was lower than blind for IB (P<0.05). Results will be completed with consumer preferences and willingness to pay for TPP and innovations in TPP. Funded by European Union’s H2020 RIA program (grant agreement no. 634476).

See the concise conclusion below as well as the full article with background and justification in PDF & DOCX formats for download. ### RECOMMENDATION We recommend that Myotis lucifigus alascensis, M. l. carissima, M. l. pernox, and M. l. relictus should continue to be recognized as subspecies of Myotis lucifugus, at least until such time as more conclusive information is provided supporting their elevation to species status. This argues against the conclusions presented by Morales & Carstens (2018).

description: The most challenging problem in the implementation of the so-called \textit{unified transform} to the analysis of the nonlinear Schrödinger equation on the half-line is the characterization of the unknown boundary value in terms of the given initial and boundary conditions. For the so-called \textit{linearizable} boundary conditions this problem can be solved explicitly. Furthermore, for non-linearizable boundary conditions which decay for large $t$, this problem can be largely bypassed in the sense that the unified transform yields useful asymptotic information for the large $t$ behavior of the solution. However, for the physically important case of periodic boundary conditions it is necessary to characterize the unknown boundary value. Here, we first present a perturbative scheme which can be used to compute explicitly the asymptotic form of the Neumann boundary value in terms of the given $τ$-periodic Dirichlet datum to any given order in a perturbation expansion. We then discuss briefly an extension of the pioneering results of Boutet de Monvel and co-authors which suggests that if the Dirichlet datum belongs to a large class of particular $τ$-periodic functions, which includes $\{a \exp(i ωt) \, | \, a>0, \, ω\geq a^2\}$, then the large $t$ behavior of the Neumann value is given by a $τ$-periodic function which can be computed explicitly.

 Author's note: this taxonomic decision is part of a series by members of the Global Bat Taxonomy Working Group to help settle ongoing disputes in the taxonomic literature and suggest targets for data collection. See the concise conclusion below as well as the full article with background and justification in PDF & DOCX formats for download. ### RECOMMENDATION We recommend the following: The burden of proof should be on overturning the species-level status of Myotis keenii, which has been recognized consistently by taxonomic authorities since 1979 and is thus the prevailing usage in need of rebuttal (see Simpson (1945)). Furthermore, in light of recent suggestions by Morales et al. (2017) that currently recognized subspecies of Myotis lucifugus should be considered distinct full species, retaining M. keenii as a distinct species, pending further analyses, reduces the risk of multiple changes and hence promotes taxonomic stability; Full genome-wide data on the sharing of single nucleotide polymorphisms (SNPs; e.g., using ddRADseq or shotgun sequencing aligned to a reference genome) should be gathered across the geographic distributions of both M. evotis and M. keenii;  A portion of the geographic samples should be vouchered so that all relevant cranial and skeletal measurements can be directly compared to genetic data; and These analyses should include specimens from the type localities of M. keenii, and each of the currently recognized subspecies of M. evotis, at least for those subspecies known to occur in the USA and Canada (evotis, pacificus, chrysonotus and jonesorum) (or even the types themselves for those that are still extant and in a condition that would allow for archival DNA sequencing).

description: Extensive farming systems produce for the society goods and services definable as public goods (biodiversity…), or having public good features (landscape attractiveness…). The provision of these public goods may not be guaranteed due to the lack of recognition of their values in markets and policies that ultimately can put in risk the future of these systems. Within TREASURE project, a choice experiment (CE) survey was applied to assess the social demand for relevant attributes of the Noir de Bigorre (NB) French regional pork chain producing Gascon local pig breed in extensive system with public good character. CE is an economic valuation method estimating the social demand for a given attribute or for combinations of them in management scenarios. Five relevant attributes of the NB chain and their current and potential levels in alternative management options were identified from focus groups: probability of existence of the breed in next 25 years, farm size, feedstuff origin, geographical availability of the products and type of selling places. A monetary attribute was included to assess the social demand for the previous attributes. A valuation questionnaire was administered to 418 individuals (365 through web-based survey, 53 face-to-face), half of them located in the South West of France, i.e. the production area of the NB chain. Results of the CE showed that the respondents had a distinctively urban profile, with no agricultural family background. Almost 40% of the respondents did not know or consume products from the NB chain. On average guaranteeing the survival of the breed achieved the highest willingness to pay (112.37 €/household/year). Respondents were willing to pay 42.35€ to maintain equal number of small and medium farms and 21.86€ to have feedstuff produced in the proximity of the farms. Geographical availability and selling places of products contributed to a lesser extent to shape their preferences. Funded by European Union’s H2020 RIA program (grant agreement no. 634476).

description: One of the most essential aspects of cuprate superconductors is a large pseudogap coexisting with a superconducting gap, then some anomalous properties can be understood in terms of the formation of the pseudogap. Within the kinetic energy driven superconducting mechanism, the effect of the pseudogap on the infrared response of cuprate superconductors in the superconducting-state is studied. By considering the interplay between the superconducting gap and pseudogap, the electron current-current correlation function is evaluated based on the linear response approach and it then is employed to calculate finite-frequency conductivity. It is shown that in the underdoped and optimally doped regimes, the transfer of the part of the low-energy spectral weight of the conductivity spectrum to the higher energy region to form a midinfrared band is intrinsically associated with the presence of the pseudogap.

description: We study existence, stability, and dynamics of linear and nonlinear stationary modes propagating in radially symmetric multi-core waveguides with balanced gain and loss. We demonstrate that, in general, the system can be reduced to an effective ${\cal PT}$-symmetric dimer with asymmetric coupling. In the linear case, we find that there exist two modes with real propagation constants before an onset of the ${\cal PT}$-symmetry breaking while other modes have always the propagation constants with nonzero imaginary parts. This leads to a stable (unstable) propagation of the modes when gain is localized in the core (ring) of the waveguiding structure. In the case of nonlinear response, we show that an interplay between nonlinearity, gain, and loss induces a high degree of instability, with only small windows in the parameter space where quasi-stable propagation is observed. We propose a novel stabilization mechanism based on a periodic modulation of both gain and loss along the propagation direction that allows bounded light propagation in the multi-core waveguiding structures.
