AbstractBackground & AimsDirect‐acting antiviral (DAA) therapy has revolutionized treatment for the hepatitis C virus (HCV). While DAA therapy is common, little is known about the intrahepatic immunological changes after sustained virologic response (SVR). We aim to describe transcriptional alterations of the gut microbiome and the liver after SVR.MethodsTwenty‐two HCV patients were evaluated before and 9 months after 12 weeks of sofosbuvir/velpatasvir treatment. All achieved SVR. A liver biopsy, portal blood (direct portal vein cannulation), peripheral blood and stool samples were obtained. RNA‐seq and immunofluorescent staining were performed on liver biopsies. RNA‐seq and 16S rRNA metagenomics were performed on stool.ResultsDifferential expression within liver transcription showed 514 downregulated genes (FDR q < .05; foldchange > 2) enriched in inflammatory pathways; of note, GO:0060337, type 1 IFN signalling (p = 8e‐23) and GO:0042742, defence response to bacterium (p = 8e‐3). Interestingly, microbial products increased in the portal blood and liver after SVR. Due to the increase in microbial products, the gut microbiome was investigated. There was no dysbiosis by Shannon diversity index or Bacteroides/Firmicutes ratio. There was a differential increase in genes responsible for bacterial lipopolysaccharide production after SVR.ConclusionsThe decrease in the antiviral interferon pathway expression was expected after SVR; however, there was an unanticipated decrease in the transcription of genes involved in recognition and response to bacteria, which was associated with increased levels of microbial products. Finally, the alterations in the function of the gut microbiome are a promising avenue for further investigation of the gut‐liver axis, especially in the context of the significant immunological changes noted after SVR.
Aquinas on the Nature of Lying
Authors: Brower Jeffrey E. 
Published: September 2023

AbstractAquinas's views about the morality of lying are well known and often discussed by commentators. But his views about the nature of lying have yet to receive the attention they deserve. In this article, I take some of the first steps necessary to correct this state of affairs by clarifying and offering a limited defense of the account of lying that Aquinas presents in in his Summa Theologiae—more specifically, in that portion of it known as the treatise on truth (Part 2-2, Questions 109–113).

SummaryWhile obesity prevention represents an established field of research, the inclusion of young people, who are regularly cited as an important priority group, are rarely actioned in long‐term studies. This paper focuses on the development of a dialogue tool intended to tackle this issue, engaging, and eliciting insights on the theme of obesity prevention, by young people and for young people. As part of the CO‐CREATE project, this tool was co‐developed by designers, public health, and youth participation experts, researchers, and young people. Co‐creation is a key methodology in the design of the dialogue tool, as young people were involved in all stages of the development process. This paper elaborates on the process of co‐designing a dialogue tool that helps explore obesity prevention policy ideas from multiple perspectives, and describes the design principles that informed the process and the final versions of the tool. The purpose of the Dialogue Forum tool is for youth to engage policymakers and other relevant stakeholders to discuss and refine co‐created and youth‐initiated ideas for healthier food and physical activity environments. We analyze how specific design principles were integrated into different prototypes and the value of this within the project and the field.
Weak texture remote sensing image matching based on hybrid domain features and adaptive description method
Authors: Yang Wupeng , Yao Yongxiang , Zhang Yongjun , Wan Yi 
Published: September 2023

AbstractWeak texture remote sensing image (WTRSI) has characteristics such as low reflectivity, high similarity of neighbouring pixels and insignificant differences between regions. These factors cause difficulties in feature extraction and description, which lead to unsuccessful matching. Therefore, this paper proposes a novel hybrid‐domain features and adaptive description (HFAD) approach to perform WTRSI matching. This approach mainly provides two contributions: (1) a new feature extractor that combines both the spatial domain scale space and the frequency domain scale space is established, where a weighted least square filter combined with a phase consistency filter is used to establish the frequency domain scale space; and (2) a new log‐polar descriptor of adaptive neighbourhood (LDAN) is established, where the neighbourhood window size of each descriptor is calculated according to the log‐normalised intensity value of feature points. This article prepares some remote sensing images under weak texture scenes which include deserts, dense forests, waters, ice and snow, and shadows. The data set contains 50 typical image pairs, on which the proposed HFAD was demonstrated and compared with state‐of‐the‐art matching algorithms (RIFT, HOWP, KAZE, POS‐SIFT and SIFT). The statistical results of the comparative experiment show that the HFAD can achieve the accuracy of matching within two pixels and confirm that the proposed algorithm is robust and effective.
Insider‐allies: The precarious politics of men in identity‐fluid feminism
Authors: Hartless Jaime 
Published: September 2023

AbstractAcademic and activist conversations about the position of men in feminism often operate under the assumption that women are the movement's key beneficiaries and men are privileged outsiders lending their support. I use 59 interviews from a broader project on feminist and LGBTQ+ activism in the United States to illustrate how men's orientation to feminism is shaped by whether social movement organizations adopt what I call woman‐centered or identity‐fluid politics. While woman‐centered politics treat men as allies whose intentions must be vetted by women, identity‐fluid feminism imagines men as insiders with their own independent investment in the movement. I argue that the tension between these two models of identity politics gives men a liminal “insider‐ally” position within feminism. Although feminist men are given a tentative authority to speak for the movement, the persistence of woman‐centered understandings of feminism means men's insider status is contested, especially when they dominate feminist spaces, compromise women's sense of safety, and seek leadership.
Thinking of threats: Economic threat appraisals and health threat appraisals predict differential racial attitudes during COVID‐19
Authors: Gallagher Natalie M. , Daley Jordan S. , Bodenhausen Galen V. 
Published: September 2023

AbstractWe examined whether perceptions of the health and economic threats posed by COVID‐19 predict different patterns of intergroup attitudes, using data gathered during the early phase of the pandemic. Using data from 1339 geographically and politically diverse White US residents, we show that subjective economic threat predicted general anti‐outgroup attitudes, while subjective health threat predicted negative attitudes towards both Asian and Latinx (“stereotypically foreign”) outgroups but not towards other outgroups. Among 303 geographically and politically diverse Black US residents, the pattern instead suggested that threat (regardless of type) was associated with reduced evaluative differentiation between racial ingroups and outgroups.

AbstractObjectivesExtended‐spectrum beta‐lactamase‐producing Enterobacteriaceae (ESBL‐PE) are spreading globally. However, respective data from African communities including livestock and environmental specimens are rare. In a rural community of southern Rwanda, we assessed intestinal carriage of ESBL‐PE among residents and livestock as well as presence in household specimens and examined associated factors.MethodsSamples of humans and livestock (both rectal swabs), soil, water, vegetables and animal products were collected within 312 community households in Sovu, Southern Rwanda. Specimens were screened for ESBL‐PE on chromogenic agar, and susceptibility to common antibiotics was determined by disc diffusion assays. Socio‐demographic information was collected with questionnaires focusing on the socio‐economic background, alimentation, living conditions, hygiene measures and medical history of the participants.ResultsData and specimens from 312 randomly selected households including 617 human beings, 620 livestock and of approximately each 300 kitchen vegetables, animal products, soil and drinking water were analysed. Overall, 14.8% of 2508 collected samples were positive for ESBL‐PE; figures were highest for humans (37.9%) and livestock (15.6%), lower for vegetables (3.8%) and animal products (3.3%), and lowest for soil (1.6%) and water (0.6%). Most detected ESBL‐PE were Escherichia coli (93.5%) in addition to Klebsiella pneumoniae (6.5%). Cross‐resistance to ampicillin‐sulbactam, ciprofloxacin and co‐trimoxazole was common. Logistic regression identified increasing age, another ESBL‐PE positive household member, prolonged time for fetching water, current diarrhoea and the ability to pay school fees as independent predictors of intestinal ESBL‐PE carriage among community members.ConclusionsESBL‐PE carriage is common in a rural Rwandan farming community. Carriage in livestock is not associated with human carriage. Associated factors suggest few addressable risk factors. The data indicate that in southern Rwanda, ESBL‐PE are no longer primarily hospital‐based but circulate in the community.

AbstractBackground and ObjectivesSecuring an adequate blood supply relies on accurate knowledge of blood donors and donation practices. As published evidence on Asian populations is sparse, this study aims to gather up‐to‐date information on blood donors and donation practices in Asia to assist planning and strategy development.Materials and MethodsTen blood collection agencies (BCAs) provided 12 months' data on donors who met eligibility criteria or were deferred, as well as details of their donation practices. Body mass index and blood volumes were calculated and analysed.ResultsData on 9,599,613 donations and 154,834 deferrals from six national and four regional BCAs revealed varied donation eligibility and collection practices. Seven used haemoglobin (Hb) criteria below the World Health Organization anaemia threshold. Seven accepted donors weighing <50 kg. Data collection on the weight and height of donors and on deferrals was inconsistent, often not routine. Deferred donors appear to weigh less, with corresponding lower estimated blood volume.ConclusionThe diversity in eligibility criteria and donation practices reflects each BCA's strategy for balancing donor health with securing an adequate blood supply. Use of lower Hb criteria substantiate their appropriateness in Asia and indicate the need to define Hb reference intervals relevant to each population. We encourage routine gathering of donor weight and height data to enable blood volume estimation and local optimization of donation volumes. Blood volume estimation formulae specific for the Asian phenotype is needed. Information from this study would be useful for tailoring donation criteria of Asian donors around the world.
Interval groups related to finite Coxeter groups Part II
Authors: Baumeister Barbara , Holt Derek F. , Neaime Georges , Rees Sarah 
Published: September 2023

AbstractWe provide a complete description of the presentations of the interval groups related to quasi‐Coxeter elements in finite Coxeter groups. In the simply laced cases, we show that each interval group is the quotient of the Artin group associated with the corresponding Carter diagram by the normal closure of a set of twisted cycle commutators, one for each 4‐cycle of the diagram. Our techniques also reprove an analogous result for the Artin groups of finite Coxeter groups, which are interval groups corresponding to Coxeter elements. We also analyse the situation in the non‐simply laced cases, where a new Garside structure is discovered. Furthermore, we obtain a complete classification of whether the interval group we consider is isomorphic or not to the related Artin group. Indeed, using methods of Tits, we prove that the interval groups of proper quasi‐Coxeter elements are not isomorphic to the Artin groups of the same type, in the case of when is even or in any of the exceptional cases. In Baumeister et al. (J. Algebra 629 (2023), 399–423), we show using different methods that this result holds for type for all .
Direct Numerical Simulation of a High-Pressure Turbine Stage: Unsteady Boundary Layer Transition and the Resulting Flow Structures
Authors: Wang Taiyang , Zhao Yaomin , Leggett John , Sandberg Richard D. 
Published: September 2023

Abstract
In the present study, we investigate the unsteady boundary layer transition based on the direct numerical simulation database of a high-pressure turbine (HPT) stage (Zhao and Sandberg, 2021, High-Fidelity Simulations of a High-Pressure Turbine Stage: Effects of Reynolds Number and Inlet Turbulence, ASME Turbo Expo 2021, Paper No. GT2021-58995), focusing on the transition mechanisms on the rotor blade, affected by the incoming periodic wakes and the background freestream turbulence (FST). On the basis of the fully resolved flow fields, we provide detailed analysis of the flow structures responsible for the transition, and two distinctive transition paths have been identified. The first path is the typical bypass transition via the instability of Klebanoff streaks, which happens when the transition region is not directly affected by the wake. The suction-side boundary layer is disturbed at the leading edge, resulting in the formation of streamwise streaks. These streaky structures endure varicose instability in the region with adverse pressure gradient (APG), then quickly break down into turbulent spots, which then evolve into fully turbulent flow. The other transition path is a consequence of the direct interaction between the wake structures and the blade boundary layer, when the wake apex starts to affect the transitional region. To be specific, the wake structures directly interact with the separation bubble in the APG region, causing sudden breakdown into turbulence. A calmed region is found to follow the wake-induced turbulent boundary layer. It is observed that the recovery to a calmed region can be impacted by the FST, as the calmed region in case with no FST is much longer compared to cases with stronger FST.
Experimental and Numerical Investigations on Flexible Paraffin/Fiber Composite Phase Change Material

Published: September 2023

Abstract
A flexible paraffin/hollow fiber phase change composite was prepared using a simple impregnation method, and the thermal-release performance of a piece of woven paraffin/hollow fiber rectangular blocks was systematically investigated using experimental and numerical methods. The experimental results of the thermal-release performance were highly consistent with the numerical results. Consequently, the thermal-release performance, including the available energy and solidification time, of the paraffin/hollow fiber with different melting temperatures, mass fractions (corresponding to the enthalpy), specific heat, and thermal conductivity were numerically investigated. The available energy of the paraffin/hollow fiber completely depends on the mass fraction of the paraffin. The solidification time mainly depends on the mass fraction of the paraffin and secondarily on the thermal conductivity, while the specific heat has little effect on the solidification time. Therefore, the thermal-release performance of the paraffin/hollow fiber could be optimized through numerical simulation by altering the solidification temperature, mass fraction, thermal conductivity, and specific heat.
ImpersonatAR: Using Embodied Authoring and Evaluation to Prototype Multi-Scenario Use Cases for Augmented Reality Applications
Authors: Wu Meng-Han , Ipsita Ananya , Huang Gaoping , Ramani Karthik , Quinn Alex 
Published: September 2023

Abstract
Prototyping use cases for augmented reality (AR) applications can be beneficial to elicit the functional requirements of the features early-on, to drive the subsequent development in a goal-oriented manner. Doing so would require designers to identify the goal-oriented interactions and map the associations between those interactions in a spatio-temporal context. Pertaining to the multiple scenarios that may result from the mapping, and the embodied nature of the interaction components, recent AR prototyping methods lack the support to adequately capture and communicate the intent of designers and stakeholders during this process. We present ImpersonatAR, a mobile-device-based prototyping tool that utilizes embodied demonstrations in the augmented environment to support prototyping and evaluation of multi-scenario AR use cases. The approach uses: (1) capturing events or steps in the form of embodied demonstrations using avatars and 3D animations, (2) organizing events and steps to compose multi-scenario experience, and finally (3) allowing stakeholders to explore the scenarios through interactive role-play with the prototypes. We conducted a user study with ten participants to prototype use cases using ImpersonatAR from two different AR application features. Results validated that ImpersonatAR promotes exploration and evaluation of diverse design possibilities of multi-scenario AR use cases through embodied representations of the different scenarios.
A Simulation Study of Factors Affecting Cooling Performance of a Fan Wall-Cooled Data Center
Authors: Ling Wei , Bi Zhaoyang , Chen Tailian 
Published: September 2023

Abstract
In this paper, numerical study of airflow in high-density data center with fan wall is conducted to study the factors affecting the cooling performance of high-density data centers. The factors considered are air outlet layout, orifice plate setting, and closed cold aisle. The total heat load in the computer room is 470 kW, and the single frame is 7 kW. The results show that there is no significant difference between installing the orifice plate and not installing the orifice plate. When the porosity of the orifice plate is less than 40 %, the airflow uniformity after the orifice plate is obviously improved, but the airflow path is greatly blocked, resulting in the inlet temperature of the middle and rear cabinets exceeding the thermal safety range. The high porosity of orifice plate has little effect on improving refrigeration effect. Changing the layout of the vent is a measure that has a significant impact on airflow management. The vertical cold aisle arrangement of the vent can make the airflow path more reasonable. The addition of partially closed cold aisle greatly reduces the mixing of hot and cold air, and the utilization rate of outdoor low-temperature cooling can be improved by increasing the supply air temperature, thereby reducing carbon emissions and further moving towards a low-carbon data center.
Numerical Study of Solar Receiver Tube With Modified Surface Roughness for Enhanced and Selective Absorptivity in Concentrated Solar Power Tower

Published: September 2023

Abstract
Concentrated solar power (CSP) is a reliable renewable energy source that is progressively lowering its cost of energy. However, the heat loss due to reflected and emitted radiation hinders the maximum achievable thermal efficiency for solar receiver tubes on the solar tower. Current solar selective coatings cannot withstand the high temperatures that come with state-of-the-art CSP towers often needing to be recoated soon after initial operation. We intend to use Inconel 718 with different additive manufacturing (AM) practices to construct surfaces that allow for more light-trapping to occur. By adjusting printing parameters, we can tailor a surface to allow for more absorption while diminishing emitted radiation heat loss. By using COMSOL Multiphysics, we can generate these theoretical surfaces to emulate a printed surface, and using the coupled Multiphysics we can simulate how the surface dictates radiation properties. Our results show that by having a rougher surface we can enhance the absorptivity of Inconel 718 (IN718) by 38.8%. We expect this work to transform how solar absorber tubes are manufactured without using selective coatings and supplement the US Department of Energy (DOE) 2030 SunShot Initiative.
Feasibility of High Temperature Concentrated Solar Power for Cogeneration of Electricity and Hydrogen Using Supercritical Carbon Dioxide Receiver Technology
Authors: Khormi Nader A. , Fronk Brian M. 
Published: September 2023

Abstract
The objective of this study is to evaluate the feasibility of cogeneration of electricity and hydrogen using a high temperature, concentrated solar power central receiver with supercritical carbon dioxide as the working fluid. Carbon dioxide is heated directly in a high efficiency receiver to a temperature of 720°C, which then provides thermal input in series to a supercritical carbon dioxide (sCO2) Brayton cycle for producing electricity and then to a thermochemical hydrogen production cycle. Three different methods of producing hydrogen are examined: the 4-step copper-chlorine (Cu-Cl) thermochemical cycle, the hybrid sulfur (HyS) thermochemical cycle, and two different electrolyzers: the alkaline electrolyzer and the polymer exchange membrane electrolyzer. Simulations developed in Aspen Plus were used to estimate the thermochemical hydrogen production efficiency, while the solar receiver and sCO2 Brayton cycle performance were based on results of prior work. The initial results show that the overall solar-to-electricity and H2 efficiencies for the Cu-Cl cycle, hybrid sulfur cycle, alkaline electrolyzer, and polymer exchange membrane electrolyzer are 39.6%, 26.1%, 29.6%, and 22.8%, respectively. These systems’ hydrogen capacities are 864, 715, 524, and 403 kg/h, respectively, for an equivalent sCO2 Brayton cycle.
