Study on thermal insulation and seismic effect for fault-crossing tunnel in high geothermal area
Authors: Cui Guangyao , Shi Wenhao 
Published: July 2022

AbstractThe fault-crossing tunnel in high geothermal areas can be severely damaged under strong earthquake. In this paper, numerical models were established in Flac3d to investigate the thermal insulation and seismic effects under the strong earthquake when using highly damped composite structure. The results showed that the thermal insulation effect of the PC, the PC highly damped composite structure and the SFRC highly damped composite structure were almost the same, which the PC highly damped composite structure was slightly better. After applying the highly damped composite structure, the maximum and minimum principal stresses on the lining decreased, it showed that highly damped composite structure could enhance the seismic effect of tunnel. The safety factor of SFRC highly damped composite structure was 2.420, which was a 28.14% increase compared to PC. Based on numerical simulations, the thermal insulation and seismic effect of SFRC highly damped composite structure was better than other seismic measures. The research can provide a reference for the design of thermal insulation and anti-earthquake for fault-crossing tunnel under strong earthquake in high geothermal area.

Published: July 2022

AbstractEvolution of the direct, monosynaptic connection from the primary motor cortex to the spinal cord parallels acquisition of hand dexterity and lateralization of hand preference. In non-human mammals, the indirect, multi-synaptic connections between the bilateral primary motor cortices and the spinal cord also participates in controlling dexterous hand movement. However, it remains unknown how the direct and indirect corticospinal pathways work in concert to control unilateral hand movement with lateralized preference in humans. Here we demonstrated the asymmetric functional organization of the two corticospinal networks, by combining network modelling and simultaneous functional magnetic resonance imaging techniques of the brain and the spinal cord. Moreover, we also found that the degree of the involvement of the two corticospinal networks paralleled lateralization of hand preference. The present results pointed to the functionally lateralized motor nervous system that underlies the behavioral asymmetry of handedness in humans.

Published: July 2022

AbstractPsychological resilience has emerged as a key factor in mental health during the global COVID-19 pandemic. However, no work to date has synthesised findings across review work or assessed the reliability of findings based on review work quality, so as to inform public health policy. We thus conducted a meta-review on all types of review work from the start of the pandemic (January 2020) until the last search date (June 2021). Of an initial 281 papers, 30 were included for review characteristic reporting and 15 were of sufficient review quality for further inclusion in strategy analyses. High-level strategies were identified at the individual, community, organisational, and governmental levels. Several specific training and/or intervention programmes were also identified. However, the quality of findings was insufficient for drawing conclusions. A major gap between measuring the psychological resilience of populations and evaluating the effectiveness of strategies for those populations was revealed. More empirical work, especially randomised controlled trials with diverse populations and rigorous analyses, is strongly recommended for future research.

Output tracking control of non‐minimum phase systems using on‐line output redefinition approach based on barrier function method
Authors: Jahangiri Fatemeh , Yadegar Meysam 
Published: July 2022

AbstractThis paper considers the output tracking problem of non‐minimum phase non‐linear systems using the inverse dynamics control which is impossible in conventional methods due to unstable zero dynamics. The proposed method is based on the output redefinition approach defined as a parametric function. The tracking error is decomposed into two terms. The first one named redefined output tracking error is the difference between the redefined output and the reference signal, and the second one is the distance between the redefined output and the system output. For the first term, due to minimum phase property of the system with the redefined output, an inverse dynamics control is used to guarantee the convergence of the redefined output tracking error to zero. To minimize the second term, the parameters of the redefined output are set by solving an optimization problem whose constraints include minimum phase conditions. To solve the optimization problem which satisfies all constraints, the barrier function method as an interior point method is adopted. The optimization parameters are set using steepest descent algorithm. Due to on‐line updating the redefined output parameters, the related zero dynamics is time varying. Therefore, sufficient conditions for exponential stability of the resulting time‐varying zero dynamics are obtained.

Published: July 2022

AbstractIn this article, an adaptive fuzzy finite‐time fault‐tolerant control (FTC) scheme for uncertain non‐linear systems under sensor faults is proposed. Compared with the existing methods, the considered system contains unknown time‐varying fault parameters, uncertain non‐linear functions, and can guarantee the performance of the system in finite time. The coupling between fault parameters and actual states is solved by the fault parameters separation method. The fuzzy logic system (FLS) is used to approximate the unknown functions, and combining the backstepping technology an adaptive fault‐tolerant controller is designed. The finite‐time stability of the closed‐loop system is proved by the Lyapunov theory. At last, the numerical simulation and the real physical system simulation verified the effectiveness of the proposed scheme.
Optimal operation and sizing of pumped thermal energy storage for net benefits maximization
Authors: Perez Matthew , Fan Rui , Wu Di 
Published: July 2022

AbstractCurrent trends in the modern grid are leading to the development and deployment of energy storage to help integrate increasing variable renewable energy sources into the grid. This paper studies a pumped thermal energy storage (PTES) system for multiple grid services including energy arbitrage, frequency regulation, spinning and non‐spinning reserve, and resource adequacy. Optimal dispatch methods are proposed for individual services as well as value stacking from multiple services to maximize the economic benefits. Assessment results demonstrate the superiority of value stacking. Specifically, the study shows the maximum revenue from an individual grid service with a 30‐MWh PTES system was $522,520, while the value stacking could increase the benefits to $678,477. In addition, sensitivity analyses were conducted to explore the cost‐effectiveness of a PTES system with different combinations of power transfer limits and energy capacity. It was found that the power transfer limit had a greater impact than the energy capacity on the benefits. The proposed method could help determine the optimal duration of a future PTES system.
Managing power imbalance with cloud energy storage in imbalance band market environment
Authors: Baik Se Hoon , Yoon Yong Tae , Jin Young Gyu , Moon Hee Seung , Kim Seung Wan 
Published: July 2022

AbstractImbalance band market is an alternative to traditional market structures which is proposed to ensure that system frequency remains within acceptable bounds. In an imbalance band market environment, the load‐serving entities (LSEs) can purchase bands or reduce the load deviation by operating a battery energy storage system (BESS) to avoid the penalty for causing imbalance. The market concept would be effective in sharing balancing responsibility between a system operator (SO) and load‐serving entities. In this study, the authors proposed a planning framework for a load serving entity (LSE) considering cloud energy storage (CES) business as a useful resource in the imbalance band market environment. The term of cloud energy storage is used as a platform that the operator owns and operates the storage, while subscribed clients pay a service fee for requesting charging and discharging operations. The simulation results show that operating cloud energy storage business is economically rational strategy for the LSE. The authors verified that a LSE operating the cloud energy storage business under an imbalance band market environment to pursue its own benefit better performs a part of the balance‐maintaining obligation of the SO compared with a LSE not operating the cloud energy storage business.
Content‐augmented feature pyramid network with light linear spatial transformers for object detection

Published: July 2022

AbstractAs one of the prevalent components, feature pyramid network (FPN) is widely used in current object detection models for improving multi‐scale object detection performance. However, its feature fusion mode is still in a misaligned and local manner, thus limiting the representation power. To address the inherited defects of FPN, a novel architecture termed content‐augmented feature pyramid network (CA‐FPN) is proposed in this paper. Firstly, a global content extraction module (GCEM) is proposed to extract multi‐scale context information. Secondly, lightweight linear spatial Transformer connections are added in the top‐down pathway to augment each feature map with multi‐scale features, where a linearized approximate self‐attention function is designed for reducing model complexity. By means of the self‐attention mechanism in Transformer, it is no longer needed to align feature maps during feature fusion, thus solving the misaligned defect. By setting the query scope to the entire feature map, the local defect can also be solved. Extensive experiments on COCO and PASCAL VOC datasets demonstrated that the CA‐FPN outperforms other FPN‐based detectors without bells and whistles and is robust in different settings.

AbstractGlobalisation has facilitated different industries to eliminate geographical boundaries and equipped organisations to work collectively to produce goods. Pharmaceuticals is one such industry which has majorly benefited from globalisation to reduce costs and increase profitability at different aspects of research, development, manufacturing of drugs and finally distribution of drugs. Globalisation not only reduces costs and increases profits for the industry, it also makes essential medication available to all individuals even at remote areas of undeveloped, developing and developed countries. As the number of entities or participants grew in the Pharmaceutical Supply Chain (PSC), the complexity and abstractness of the drug delivery from manufacturer to consumer has increased, which raised new concerns like counterfeit medication, incorrect, incomplete or no information about the drug reaching the consumer thus undermining customer confidence and most importantly distribution delays which can cause serious impact on the life of the consumer as well as business growth. Considering all these challenges, there is a dire need for a robust PSC which can eliminate blind parties and provide a transparent chain. A transparent PSC will eliminate data fragmentation between different participating entities by creating a trail of secure, single source of truth for the entire life cycle of a medicine, thereby eliminating the introduction of counterfeits and ensuring the consumer safety. This article proposes a novel Distributed Ledger Technology (DLT) based transparent supply chain for PSC and proof‐of‐concept is implemented to analyse the scalability and efficiency of the proposed architecture. Distributed Ledger Technology (DLT) is one of the technologies which can provide such transparent PSC and Smart Contracts (SC) are the most commonly used component in such systems to implement business logic and access control mechanisms. The proposed PharmaChain model investigates all the interactions between the main entities in PSC and also addresses smart contract issues such as re‐entrance, randomness and lacking trustworthy data feed. Results are compared with other proposed solutions for PSC based on DLT.
Externally gapped line arrester performance in high voltage transmission line using frequency grounding system: Absorbed energy and expected life assessment
Authors: Khodsuz Masume 
Published: July 2022

AbstractService unavailability of transmission lines, due to the direct and indirect lightning strikes, is evaluated as a challenging issue within electric companies. The lightning event can produce dangerous overvoltage, equipment failures, and power supply interruptions. Here, externally gapped line arresters (EGLAs) performances installed on a 63 kV transmission line are modelled using EMTP‐ATP to investigate their capability to withstand current and energy discharged by lightning strokes during back flashover phenomena. Frequency behaviour of the grounding system impedance, first and subsequent lightning current parameters effects on insulators back flashover and lightning flashover failure rate have been considered by Monte‐Carlo method. Then, extensive analysis has been carried out to study the absorbed energy of the EGLA and its expected life. The results show the dependency of failure rate and the EGLA expected life on the soil resistivity and lightning strike parameters. The selected EGLA must be provided sufficient lightning protection to the transmission line based on its absorbed energy capability, the soil and lightning parameters and be complied with the discharge energy capability requirement specified by the utility company.
Impact drag force exerted on a projectile penetrating into a hierarchical granular bed
Authors: Okubo Fumiaki , Katsuragi Hiroaki 
Published: July 2022

Context. The impact of a solid object onto a small-body surface can be modeled by the solid impact onto a hierarchically structured granular target.
Aims. We develop an impact drag force model for the hierarchically structured granular target based on the experiment.
Methods. We performed a set of granular impact experiments in which the mechanical strength and porosity of target grains were systematically varied. Tiny glass beads (5 μm in diameter) were agglomerated to form porous grains of 2–4 mm in diameter. Then, the grains were sintered to control their strength. A polyethylene sphere (12.7 mm in diameter) was dropped onto a hierarchical granular target consisting of these porous grains. Motion of the penetrating sphere was captured by a high-speed camera and analyzed.
Results. We find that the impact drag force produced by the hierarchically structured granular target can be modeled by the sum of inertial drag and depth-proportional drag. The depth-proportional drag in a hierarchical granular impact is much greater than that of the usual granular target consisting of rigid grains. The ratio between the grain strength and the impact dynamic pressure is a key dimensionless parameter for characterizing this extraordinary large depth-proportional drag.
Conclusions. Grain fracturing plays an important role in the impact dynamics when the impact dynamic pressure is sufficiently larger than the grain strength. This implies that the effect of grain fracturing should be considered also for the impact on a small body. It may be that the effective strength of the surface grains can be estimated based on kinematic observations of the intrusion or touchdown of a planetary explorator.

ZusammenfassungDie chirurgische Entfernung ist derzeit die Standardtherapie für resezierbare, nicht-metastasierte Mastzelltumoren (MZT). Seit kurzem steht mit dem intratumoral angewendeten Tigilanoltiglat eine neue Therapieoption für ausgewählte kutane und subkutane MZT zur Verfügung. Hier wird die erfolgreiche Behandlung eines 0,445 cm3 großen subkutanen MZTs an der Zehe eines American Staffordshire Terriers dokumentiert. Die daraus resultierende Wunde heilte komplikationslos innerhalb von 4 Wochen vollständig ab, und der Hund zeigte 8 Monate nach Therapie kein Rezidiv. Dank des neuen Medikaments konnte die Zehe erhalten werden, während chirurgisch eine vollständige Entfernung des Tumors nur mittels Amputation der Zehe möglich gewesen wäre.

Published: July 2022

ZusammenfassungEin 10-jähriges kastriertes, männliches Minischwein wurde aufgrund eines Tenesmus vesicae mit Anurie vorgestellt. Begleitsymptom war eine Tachypnoe. Röntgenologisch waren zahlreiche Harnsteine in Blase und Urethra nachweisbar. Über die Harnröhre konnte nicht katheterisiert werden, sodass eine Notfallzystostomie mit Einlegen eines Ballonkatheters durchgeführt wurde. Trotz Blasenspülung gelang es nicht die Harnröhrensteine so auszuspülen. Deswegen wurde ein präpubisches Urethrostoma angelegt. Das Tier erholte sich vollständig und setzt seither problemlos Urin über die urethrale Fistel ab. Prophylaktische Maßnahmen der Urolithiasis beinhalten unter anderem eine ausreichende Wasseraufnahme, eine ausgewogene Fütterung und balancierte Futterzusammensetzung sowie die Gewährleistung eines physiologischen Urin-pH-Werts.

Published: July 2022

AbstractHundreds of adolescents are hospitalized in the United States yearly with anemia due to heavy menstrual bleeding (HMB). Limited data exist regarding how these patients are evaluated and how many are diagnosed with a bleeding disorder. The aim of this study was to determine the prevalence of bleeding disorders in adolescents hospitalized for HMB. Secondary aims included identification of risk factors for severe anemia leading to hospitalization and the hematology assessment. This was a retrospective cohort study of patients aged 9 to 21 years hospitalized for HMB and anemia at a tertiary care children's hospital from January 1, 2000, to December 31, 2017. A total of 118 girls hospitalized for HMB and anemia were included. Almost 30% of patients were African American. Hematology involvement did not occur in 42% of patients. Sixty patients completed bleeding disorder testing and 57% (34/60) were diagnosed with a bleeding disorder. Most patients diagnosed with von Willebrand disease (VWD) tested while hospitalized and anemic had VW levels <100%A but 9/25 (36%) girls not evaluated by Hematology also had VW levels <100%. Despite an established Inpatient Coagulation Consult service, many adolescents hospitalized with HMB did not receive an appropriate evaluation for bleeding disorders. African Americans were disproportionately hospitalized for HMB. VW levels are elevated with HMB and severe anemia, but levels <100 seem to be predictive of VWD in this setting. Further research is needed to determine optimal timing of bleeding disorder evaluation, but many adolescents hospitalized for HMB may have an underlying bleeding disorder.

Published: July 2022

AbstractWe report a highly branch-selective and enantioselective allylic alkylation of simple ketones with racemic aliphatic allylic carbonates under mild conditions. By using a Rh–bisoxazolinephosphine system and catalytic amounts of a base in THF, a series of chiral β-branched γ,δ-unsaturated ketones were obtained with excellent regio- and enantioselectivities. An outer-sphere nucleophilic substitution C–C bond-formation process is proposed on the basis of mechanistic studies.
