The Regional Coupled Suite (RCS-IND1): application of a flexible regional coupled modelling framework to the Indian region at km-scale

Abstract. A new regional coupled modelling framework is introduced – the Regional Coupled Suite (RCS). This provides a flexible research capability with which to study the interactions between atmosphere, land, ocean and wave processes resolved at km-scale, and the effect of environmental feedbacks on the evolution and impacts of multi-hazard weather events. A configuration of the RCS focussed on the Indian region, termed RCS-IND1, is introduced. RCS-IND1 includes a regional configuration of the Unified Model (UM) atmosphere, directly coupled to the JULES land surface model, on a grid with horizontal spacing of 4.4 km, enabling convection to be explicitly simulated. These are coupled through OASIS3-MCT libraries to 2.2 km grid NEMO ocean and WAVEWATCH III wave model configurations. To examine a potential approach to reduce computation cost, and simplify ocean initialisation, the RCS includes an alternative approach to couple the atmosphere to a lower resolution Multi-Column K Profile Parameterization (KPP) for the ocean. Through development of a flexible modelling framework, a variety of fully and partially coupled experiments can be defined, along with traceable uncoupled simulations and options to use external input forcing in place of missing coupled components. This offers a wide scope to researchers designing sensitivity and case study assessments. Case study results are presented and assessed to demonstrate the application of RCS-IND1 to simulate two tropical cyclone cases which developed in the Bay of Bengal, namely Titli in October 2018 and Fani in April 2019. Results show realistic cyclone simulations, and that coupling can improve the cyclone track and produces more realistic intensification than uncoupled simulations for Titli but prevents sufficient intensification for Fani. Atmosphere-only UM regional simulations omit the influence of frictional heating on the boundary layer to prevent cyclone over-intensification. However, it is shown that this term can improve coupled simulations, enabling a more rigorous treatment of the near-surface energy budget to be represented. For these cases, a 1D mixed layer scheme shows similar first-order SST cooling and feedback on the cyclones as a 3D ocean. Nevertheless, the 3D ocean generally shows stronger localised cooling than the 1D ocean. Coupling with the waves have limited feedback on the atmosphere for these cases. Priorities for future model development are discussed.
Local free fatty acids trigger the expression of lipopolysaccharide-binding protein in murine white adipose tissue

Although lipopolysaccharide (LPS)-binding protein (LBP) is an acute-phase protein mainly produced by hepatocytes, it has also been proposed to be a pro-inflammatory adipokine. Obesity and the consumption of a high-fat diet (HFD) are reportedly associated with elevated levels of LPS in plasma and free fatty acids (FFAs) in white adipose tissue (WAT). We examined whether circulating LPS or local FFAs are responsible for the HFD-induced increase of LBP in WAT. Male C57BL/6J mice were fed either a normal-fat diet (NFD) or an HFD. The mRNA levels in the liver and mesenteric WAT (mWAT), total FFA content in mWAT, and LBP and LPS concentrations in plasma were determined. The Lbp mRNA level in mWAT was higher in mice fed the HFD than in those fed the NFD for 3, 7, or 28 days or 14 weeks, whereas the hepatic Lbp mRNA level did not differ between the groups. The Lbp mRNA level in mWAT was also increased by the HFD in germ-free mice, which do not have gut microbiota, the source of LPS. The plasma LPS level did not show a significant correlation with the mWAT Lbp mRNA level. The total FFA content in mWAT was higher in mice fed the HFD than in those fed the NFD and positively correlated with the Lbp mRNA level. Supplementation with palmitic acid increased the Lbp mRNA level in 3T3-L1 adipocytes. We propose that local FFAs, but not circulating LPS, are the trigger for increased Lbp expression in mWAT of mice fed the HFD.
How do Sociodemographic Characteristics Influence UK Civilian Opinions of UK Armed Forces Iraq and Afghanistan Veterans? A Mixed-Method Approach

Evidence suggests that UK veterans are seen as victims with concern for their perceived mental health needs. This study examined sociodemographic factors that contribute to victimizing conceptualizations of British Army Iraq and Afghanistan veterans. UK participants (N = 234) provided three word associations to “British Army Iraq Veteran” and “British Army Afghanistan Veteran” and answered sociodemographic questions. A multiple linear regression outlines that low national pride, mission opposition and higher levels of education predict elevated victimizing word associations. Narrative accounts from UK interviews (N = 21) suggest that participants who perceived the recent conflicts as illegitimate conceptualize veterans as passive, naïve actors who had to submit to the agency of the anthropomorphic described government. This allowed holding overtly appreciative though belittling attitudes toward veterans, while opposing the missions. To dissociate veterans from victimizing perceptions, better knowledge about service and justifications for deployments need to be provided. Study limitations, including over sampling of young adult females, are discussed.
Flex-PCB Quench Antenna Developments at FNAL

Flexible printed-circuit-board-based quench antenna arrays have been developed at FNAL since 2017. They proved to be low-noise, low-cost, sensitive, and non-invasive sensors for quench characterization in superconducting magnets, having the potential to extend even to quench detection. Starting with applications of small area sensors of this type, we have explored feasibility for operations at high pressure, and have invested in multi-channel quench antenna arrays covering the complete area of the innermost magnet layer of the conductor. We've also tested and optimized sensor geometry and relative orientations to increase sensitivity and spatial resolution. Beyond developments of warm and cold bore antennas, we've progressed to concepts which attach quench antennas to the conductor surfaces of accelerator magnets. Multiple programs and projects at FNAL and collaborating institutions benefited from this work already and our plans target further extensions of capabilities and applicability of these devices. In this paper we present the logic behind the development steps taken so far, status of our work and direction of near-term research on quench antennas at Fermilab.
Pilot-Scale Biological Activated Carbon Filtration–Ultrafiltration System for Removing Pharmaceutical and Personal Care Products from River Water

Biological activated carbon (BAC) biofilter coupling ultrafiltration (UF) is a promising process for the treatment of river water contaminated by pharmaceutical and personal care products (PPCPs). However, the pilot-scale study should be conducted to reveal the long-term removal performance and the respective contributions of BAC and UF. In this study, a BAC-UF system with treatment capacity of 0.16 m3 h−1 was operated for 130 days. The water quality was analyzed in terms of CODMn, UV254, NH4+-N, and PPCPs. The results showed that both BAC and UF were related to the removal of organic matter (CODMn and UV254), achieving the removals of 56.00% and 55.25%, respectively. Similarly, BAC and UF were both relevant to the removal effects of ammonia nitrogen, nitrite, and nitrate. Moreover, the BAC-UF process was featured with a high efficiency in the removal of PPCPs, and the average removal of total PPCPs reached 47.84%, especially anhydroerythromycin, sulfachloropyridazine, sulfadiazine, trimethoprim, and caffeine. Besides, it was found that the BAC unit played a key role in PPCPs removal and the UF unit also degraded them by the biomass on UF membranes. Therefore, this study proved the removal performance of BAC-UF for treating popular pollutants from river water, and the BAC-UF process in this work can be considered as a feasible method of producing clean drinking water.
Impact of Anthropogenic Emission Changes on the Occurrence of Equatorial Plasma Bubbles

In this work, we examine the impact of increased anthropogenic emissions on equatorial plasma bubble (EPB) occurrence by modeling the growth rate of Rayleigh‐Taylor (R‐T) instability ( γRT ${\gamma }_{RT}$ ), which is closely related to EPB generation. Using the global coupled ionosphere‐thermosphere‐electrodynamics model‐institute of geology and geophysics, Chinese Academy of Sciences model, γRT ${\gamma }_{RT}$ is calculated under three different CO2 emission levels. As CO2 increases, γRT ${\gamma }_{RT}$ significantly increases at low altitudes (<∼260 km) and decreases at high altitudes (>∼320 km). In the altitudes in between, γRT ${\gamma }_{RT}$ increases (decreases) before (after) midnight. Longitudinal variability of the γRT ${\gamma }_{RT}$ change is manifested apparently above ∼280 km, while it is insignificant for low altitudes. Term analysis revealed that changes in the gravity term and the electric‐field term are the main causes and that the neutral‐wind term is insignificant. The investigation indicates that increased anthropogenic emissions can change EPB occurrence and, in turn, the radio‐communication system and therefore influence modern technological systems, which is expected to be more serious in the future.
The effect of resveratrol on toxicity caused by cisplatin in rats with experimentally created diabetes by streptozotocin

Aim: In our study, the therapeutic effect of resveratrol against the toxicity of cisplatin in rats with experimental diabetes mellitus with streptozotocin was investigated. Material and Method: 64 rats were used in the study. 8 groups were randomly formed, with 8 rats in each group. Group 1 was determined as the control group. Group 2 (STZ) was injected with 60 mg/kg streptozotocin intraperitoneally (ip) on the first day to induce diabetes. Group 3 (RES) was given 100 mg/kg of resveratrol orally every day. Group 4 (SIS), a single dose of cisplatin 7 mg/kg (ip) was administered 3 days later. Group 5 (STZ+RES), group 6 (STZ+SIS), group 7 (RES+SIS) and group 8 (STZ+SIS+RES) were determined. Results: While there was weight gain in the control and RES groups during the experiment, the STZ and STZ + SIS groups showed a significant decrease in body weights of the rats. In the groups given streptozotocin and cisplatin together with resveratrol, there was no decrease in body weight, but a small increase was observed. In groups with increased blood glucose values with streptozotocin, these values were found to have dropped significantly with resveratrol. The TAS level has increased significantly in groups RES, STZ+RES, SIS+RES and STZ+SIS+RES according to the control group; no significant difference has been found in the other groups compared to the control group. While the AST level was significantly higher in the STZ, SIS and STZ+SIS groups compared to the control group, the ALT level was found to be significantly higher in the STZ and STZ+SIS groups compared to the control group. Creatinine was found to be significantly higher in SIS, STZ+SIS, RES+SIS and STZ+SIS+RES groups compared to the control group. The SIS group and RES+SIS and STZ+SIS+RES groups were compared, the decrease in the RES+SIS and STZ+SIS+RES groups was statistically significant. QT (ms) values increased significantly in the STZ and STZ+SIS groups compared to the control group, but there was no significant difference in the other groups. According to the control group, the heart rate per minute was found to be significantly lower in the STZ and STZ+SIS groups. Conclusion: As a result, it was seen that the use of resveratrol would be effective in reducing the increased glucose levels in the treatment of diabetes and in the treatment of possible complications.
Seismic Velocity Variations at Different Depths Reveal the Dynamic Evolution Associated With the 2018 Kilauea Eruption

Advances in noise‐based velocity change measurements have revealed anomalies before volcanic eruptions. Still, it is difficult to assign them to a certain depth based on the traditional coda wave method. Here we used volcanic tremor (1–2.5 s) and oceanic noise (3 and 3.5 s) as passive sources to calculate the Rayleigh wave velocity changes associated with the 2018 Kilauea eruption. Our simulation show that the velocity decreased at least by 5% at 1–2 km depth beneath the East Rift zone in the co‐eruption time. Before the eruption, we observed a decrease (1%) at the same depth, whereas, at the depths of 0–1 and 2–8 km, the velocity increased by 0.2%–1%. Combined with microearthquakes, The Global Positioning System data, and numerical simulation, our observations suggest that magma intrusion may open the magma dike at 1–2 km depth but induce higher compressive stress (about 3.6–14.4 MPa) in the surrounding areas.
Integrating DMSP-OLS and NPP-VIIRS Nighttime Light Data to Evaluate Poverty in Southwestern China

Poverty alleviation is one of the most important tasks facing human social development. It is necessary to make accurate monitoring and evaluations for areas with poverty to improve capability of implementing poverty alleviation policies. Here, this study introduced nighttime light (NTL) data to estimate county-level poverty in southwest China. First, this study used particle swarm optimization-back propagation hybrid algorithm to explore the potential relationship between two NTL data (the Defense Meteorological Satellite Program’s Operational Line Scan System data and the Suomi National Polar-orbiting Partnership Visible Infrared Imaging Radiometer Suite data). Then, we integrated two NTL data at the pixel level to establish a consistent time-series of NTL dataset from 2000 to 2019. Next, an actual comprehensive poverty index (ACPI) was employed as an indicator of multidimensional poverty at county level based on 11 socioeconomic and natural variables, and which could be the reference to explore the poverty evaluation using NTL data. Based on the correlation between the ACPI and NTL characteristic variables, a poverty evaluation model was developed to evaluate the poverty situation. The result showed the great matching relationship between DMSP-OLS and NPP-VIIRS data (R2 = 0.84). After calibration, the continuity and comparability of DMSP-OLS data were significantly improved. The integrated NTL data also reflected great consistency with socioeconomic development (r = 0.99). The RMSE between ACPI and the estimated comprehensive poverty index (ECPI) based on the integrated NTL data is approximately 0.19 (R2 = 0.96), which revealed the poverty evaluation model was feasible and reliable. According to the ECPI, we found that the magnitude of poverty eradication increased in southwest China until 2011, but slowed down from 2011 to 2019. Regarding the spatial scale, geographic barriers are a key factor for poverty, with high altitude and mountainous areas typically having a high incidence of poverty. Our approach offers an effective model for evaluation poverty based on the NTL data, which can contribute a more reliable and efficient monitoring of poverty dynamic and a better understanding of socioeconomic development.
Adaptive Fractional-order Non-singular Fast Terminal Sliding Mode Control Based on Fixed Time Observer

Aiming at the problem of low tracking accuracy of the manipulator in the presence of model parameter errors and external disturbance, this paper proposes an adaptive fractional-order non-singular fast terminal sliding mode (AFONFTSM) controller based on a fixed-time disturbance observer (FTDO). The controller is split into three portions. First, a fractional-order non-singular fast terminal sliding mode (FONFTSM) surface is designed to improve the tracking accuracy and convergence speed of the error state. Second, to enhance the performance of the system state in the approaching mode, an adaptive variable exponential power reaching law (AVEPRL) is designed, which changes the coefficient of the exponential term through the size of the system state. Meanwhile, adaptive control is used to modulate one item of the reaching law, which improves the anti-interference of the system. In the end, the real-time estimation of the external disturbance is carried out by the FTDO, which solves the problem that the magnitude of the external disturbance is difficult to be determined in the actual engineering. And the stability is verified by the Lyapunov theory. The simulation results display that the controller raised in this paper has better tracking precision, faster convergence speed, and stronger robustness.
Covariate‐adaptive randomization with variable selection in clinical trials

In clinical trials and causal inference, it is often critical to balance treatment allocation over influential covariates. In big data era, the number of covariates is usually very large, among which only a small fraction of them are influential to the response variable due to sparsity. However, existing studies assume that all influential covariates are known, fixed and given. In this article, we propose a procedure that can select the influential covariates from a diverging number of candidates and keep the allocation balanced among the important covariates simultaneously. Under mild regularity conditions, we show that the proposed procedure can pick out important covariates and balance treatment allocation among the important covariates consistently. Further, balancing treatment allocation can help the selection of important covariates, whereas picking out important covariates can make the randomization more efficient. Numerical studies support our theoretical discoveries for the proposed procedure. We also apply our method to a virtual redesign dataset of advertising vehicle choosing and show the advantages of the proposed procedure.
Complexity of Waterway Networks in Port Waters

The model of waterway network in port waters are constructed to investigate the complexity of the waterway in port waters. The index system for waterway network complexity,which includes degree distribution,average path length,clustering coefficient,compactness,is set according to the characteristics of the waterway network and the complex network theory. An example port is investigated and the complexity of the waterway network is determined through numerical calculation. The results of the example port investigation indicate that the degree distribution of ship routes network follows approximately the power-law distribution,typical for scale-free networks. The network has a small average path length and a relatively large clustering coefficient with the character of small-world network,featuring good accessibility but suffering vulnerability. Measures should be taken to ensure the navigation safety in the port.
Adolescents’ motivations to perpetrate hate speech and links with social norms

Hate speech has become a widespread phenomenon, however, it remains largely unclear why adolescents engage in it and which factors are associated with their motivations for perpetrating hate speech. To this end, we developed the multidimensional “Motivations for Hate Speech Perpetration Scale” (MHATE) and evaluated the psychometric properties. We also explored the associations between social norms and adolescents’ motivations for hate speech perpetration. The sample consisted of 346 adolescents from Switzerland (54.6% boys; Mage=14; SD=0.96) who reported engagement in hate speech as perpetrators. The analyses revealed good psychometric properties for the MHATE, including good internal consistency. The most frequently endorsed subscale was revenge, followed by ideology, group conformity, status enhancement, exhilaration, and power. The results also showed that descriptive norms and peer pressure were related to a wide range of different motivations for perpetrating hate speech. Injunctive norms, however, were only associated with power. In conclusion, findings indicate that hate speech fulfills various functions. We argue that knowing the specific motivations that underlie hate speech could help us derive individually tailored prevention strategies (e.g., anger management, promoting an inclusive classroom climate). Furthermore, we suggest that practitioners working in the field of hate speech prevention give special attention to social norms surrounding adolescents. El discurso de odio se ha convertido en un fenómeno generalizado. Sin embargo, todavía no está claro por qué los adolescentes se involucran en el discurso de odio y qué factores están asociados con las motivaciones para perpetrarlo. Con esta finalidad, desarrollamos una medida multidimensional, la «Escala de Motivaciones para Perpetrar Discurso de Odio» (MHATE), y evaluamos sus propiedades psicométricas. Asimismo, investigamos las asociaciones entre las normas sociales y las motivaciones para participar en el discurso de odio. La muestra estuvo compuesta por 346 adolescentes suizos (54,6% chicos; Medad=14; DT=0,96) que informaron haber perpetrado discurso de odio. Los análisis revelaron buenas propiedades psicométricas de MHATE, incluyendo adecuada consistencia interna. La subescala con mayor frecuencia fue venganza, seguida de las de ideología, conformidad con el grupo, mejora del estatus, regocijo y poder. Las normas descriptivas y la presión de iguales estuvieron relacionadas con varias motivaciones para perpetrar discurso de odio. Las normas prescriptivas, sin embargo, solo se asociaron con el poder. En conclusión, los hallazgos indican que el discurso de odio cumple varias funciones. Conocer las motivaciones específicas para el discurso de odio ayuda a derivar estrategias de intervención individualmente adaptadas (ej., manejo de la ira, promover un clima escolar inclusivo). Además, sugerimos que los profesionales que trabajan en la prevención del discurso de odio presten especial atención a las normas sociales que rodean a los adolescentes.
Aikido and world politics: a practice theory for transcending the security dilemma

In the final analysis, is the security dilemma inescapable? Or can the protagonists in world politics learn to live with never-ending insecurities and the risk of attack without producing precisely the outcomes that they wish to avoid? This article explores this fundamental problem for International Relations theory by performing a thought experiment, in which it applies lessons from aikido to world politics. A form of Japanese budo, or martial art, aikido provides practitioners with a method for harbouring insecurities, and for dealing with attacks that may or may not occur, by empathically caring for actual and potential attackers. The article builds on practice theory in assuming that any social order is constructed and internalised through practices, but also capable of change through the introduction and dissemination of new practices. Although an unlikely scenario, aikido practice could serve as such a method of fundamental transformation if widely applied in world politics. Empirical examples ranging from international apologies and security cooperation to foreign aid and peacekeeping operations are discussed, suggesting that contemporary world politics is at times already performed in accordance with aikido principles, albeit only imperfectly and partially.
