AbstractThere is paucity of data regarding the outcomes of hospitalized acute pulmonary embolism (PE) patients with heart failure (HF) and Coronavirus Disease 2019 (COVID‐19) infection. We utilized the 2020 National Inpatient Sample (NIS) Database in conducting a retrospective cohort study to investigate the outcomes of hospitalized acute PE patients with HF and COVID‐19, looking at its impact on in‐hospital mortality, thrombolysis, and thrombectomy utilization as well as hospital length of stay (LOS). A total of 23,413 hospitalized acute PE patients with HF were identified in our study, of which 1.26% (n = 295/23,413) had COVID‐19 infection. Utilizing a stepwise survey multivariable logistic regression model that adjusted for confounders, COVID‐19 infection among acute PE patients with HF was found to be an independent predictor of overall in‐hospital mortality (adjusted odds ratio [aOR]: 2.77; 95% confidence interval [CI], 1.15–6.67; p = 0.023) and thrombolysis utilization (aOR: 5.52; 95% CI, 2.57–11.84; p ≤ 0.001) compared to those without COVID‐19. However, there were comparable rates of thrombectomy utilization and LOS among acute PE patients with HF regardless of the COVID‐19 infection status. On subgroup analysis, patients with HF with reduced ejection fraction was found to be associated with increased risk for in‐hospital mortality (aOR: 3.89; 95% CI, 1.33–11.39; p = 0.013) and thrombectomy utilization (aOR: 4.58; 95% CI, 1.08–19.41; p = 0.042), whereas both HF subtypes were associated with increased thrombolysis utilization. COVID‐19 infection among acute PE patients with HF was associated with higher over‐all in‐hospital mortality and increased thrombolysis utilization but had comparable hospital LOS as well as thrombectomy utilization.

Published: April 2023

AbstractPulmonary hemangiomas are benign, relatively rare tumours. Because computed tomography (CT) findings show a variety of images, it is often difficult to distinguish hemangiomas from lung cancer and other benign tumours. We report a 63‐year‐old man who was diagnosed with a pulmonary capillary hemangioma (PCH). A right lung basal segmentectomy was performed for diagnosis and treatment. On chest CT, the lesion was shown to be a solid nodule with contrast‐enhanced margins. This finding was thought to reflect the dense vascular hyperplasia of the central part of the tumour based on the pathologic findings. Although few studies involving PCH have referred to contrast‐enhanced CT, the findings of contrast‐enhanced CT might be a valuable indicator for diagnosing PCH.

Published: April 2023

AbstractBackgroundSuturing and knotting in Natural Orifice Transluminal Endoscopic Surgery (NOTES) requires the robot not only to be able to work with multiple manipulators but also to have a high degree of dexterity. However, little attention has been paid to the design and enhancement of dexterity in multi‐manipulated robots.MethodsIn this paper, the dexterity of a new dual‐manipulator collaborative continuum robot in collaborative space is analyzed and enhanced. A kinematic model of the continuum robot was developed. The dexterity function of the robot is evaluated based on the concepts of the low‐Degree‐of‐Freedom Jacobian matrix. Then an Adaptive Parameter Gray Wolf Coupled Cuckoo Optimization Algorithm with faster convergence and higher accuracy is innovatively proposed to optimize the objective function. Finally, experiments demonstrate that the dexterity of the optimized continuum robot is enhanced.ResultsThe optimization results show that the optimized dexterity is 24.91% better than the initial state.ConclusionThrough the work of this paper, the robot for NOTES can perform suturing and knot more dexterously, which has significant implications for the treatment of digestive tract diseases.
A systematic literature review on long‐term localization and mapping for mobile robots
Authors: Sousa Ricardo B. , Sobreira Héber M. , Moreira António Paulo 
Published: April 2023

AbstractLong‐term operation of robots creates new challenges to Simultaneous Localization and Mapping (SLAM) algorithms. Long‐term SLAM algorithms should adapt to recent changes while preserving older states, when dealing with appearance variations (lighting, daytime, weather, or seasonal) or environment reconfiguration. When also operating robots for long periods and trajectory lengths, the map should readjust to environment changes but not grow indefinitely. The map size should depend only on updating the map with new information of interest, not on the operation time or trajectory length. Although several studies in the literature review SLAM algorithms, none of the studies focus on the challenges associated to lifelong SLAM. Thus, this paper presents a systematic literature review on long‐term localization and mapping following the Preferred Reporting Items for Systematic reviews and Meta‐Analysis guidelines. The review analyzes 142 works covering appearance invariance, modeling the environment dynamics, map size management, multisession, and computational topics such as parallel computing and timing efficiency. The analysis also focus on the experimental data and evaluation metrics commonly used to assess long‐term autonomy. Moreover, an overview over the bibliographic data of the 142 records provides analysis in terms of keywords and authorship co‐occurrence to identify the terms more used in long‐term SLAM and research networks between authors, respectively. Future studies can update this paper thanks to the systematic methodology presented in the review and the public GitHub repository with all the documentation and scripts used during the review process.

AbstractBioisosteres of amino acids called α‐aminophosphonates have a variety of therapeutic properties. A set of procedures involving amine, aldehydes and triethylphosphite have been utilized to synthesize these compounds in presence of Lewis acid catalysts such as lithium perchlorate via the Kabachnik‐Fields reaction. The diazonium salt of different aromatic amines affords new α‐aminophosphonate azo dyes, IIIa‐f in high yields. The structure of the newly synthesized compounds was elucidated by FT‐IR, 1HNMR, 13C‐NMR and elemental analysis. The anti‐inflammatory and antioxidant of the newly dyes was also examined. Most of the synthesized α‐aminophosphonate compounds displayed an excellent to moderate activity against COX‐1 and COX‐2. To demonstrate the relationship between the theoretical and the experimental characteristics, DFT/6‐311G++(d, p) calculations were performed to investigate the electrical and geometric properties derived from the stable structure of the compounds. The optimized dyes with printing paste conditions, were used to silk screen printing polyester, as well as their printing properties, light, washing, perspiration, rubbing, and sublimation fastness were tested. Meanwhile, the improved dyes demonstrated acceptable fastness results.

AbstractContinuous electron‐hole transfer and the ability of nanoscale materials to absorb visible light are critical for pollutant catalytic reduction. Cobalt and copper co‐doped ZnO composites were shaped by the sol‐gel solution combustion (SG‐SC) approach. The x‐ray diffraction analysis confirmed the crystalline nature and interstitial doping of copper and cobalt in the zinc oxide lattice and the development of ZnO‐CuO local contact. The PL and DRS‐UV‐vis investigations showed the NCs’ superior charge transfer and considerable redshift (from 3.17 to 2.21 eV) properties over ZnO. TEM and SEM‐EDS analyses confirmed the foam‐type surface morphology, elemental composition, and dopant distribution. The NCs showed greater potency than ZnO NPs in the catalytic reduction reactions of 4‐nitrophenol and methylene blue. Thus, the SG‐SC approach has the potential for industrially scalable catalytic pollutant reduction applications.

Published: April 2023

AbstractWhile reading digital texts requires many of the same foundational literacy skills as reading printed texts, it also requires skills that go beyond print‐based reading. In this article, we argue that the skills children need to read, understand, and communicate about digital texts is a Core Disciplinary Practice that should be addressed in the elementary grades. To do so, we explain the idea of reading digital texts as a disciplinary literacy practice, explore the features of digital texts that make them qualitatively different from printed texts, and offer approaches for explicitly teaching children how to read and interact with digital texts in ways that support their comprehension and prepare them for future disciplinary learning. In the final section, we provide teachers with three examples of digital texts they might integrate into a K‐2 science unit and offer strategies for teaching children to navigate the unique features of these texts.

Published: April 2023

AbstractRibonucleic acid (RNA) molecules are indispensable for cellular homeostasis in healthy and malignant cells. However, the functions of RNA extend well beyond that of a protein‐coding template. Rather, both coding and non‐coding RNA molecules function through critical interactions with a plethora of cellular molecules, including other RNAs, DNA, and proteins. Deconvoluting this RNA interactome, including the interacting partners, the nature of the interaction, and dynamic changes of these interactions in malignancies has yielded fundamental advances in knowledge and are emerging as a novel therapeutic strategy in cancer. Here, we present an RNA‐centric review of recent advances in the field of RNA–RNA, RNA–protein, and RNA–DNA interactomic network analysis and their impact across the Hallmarks of Cancer.This article is categorized under:

The Investigation of Overpower ΔT Triggered Mechanism and Optimizing Strategy During Reactor Trip Experiment
Authors: Yuan Zhaojun , Wu Yuting , Cheng Yanhua , Shang Chaohao , Mao Yulong , Yan Yalun 
Published: April 2023

AbstractIn some nuclear power plants, the overpower ΔT protection signal may be triggered during the reactor trip test unexpectedly, which may guide operators’ unexpected operations. A reactor trip protection control logic model is established to simulate the response of overpower ΔT protection channel and the onsite data in the period of reactor trip test, such as nuclear power, ΔI, etc., are used as inputs for this model. The results show that protection signals simulated by the model are almost consistent with the process of triggering protection signal in plant. According to the simulation, the drastic change of core ΔI during the reactor trip process is the main cause of triggering overpower ΔT protection signal. In order to reveal the mechanism of ΔI change in the process of reactor trip and develop corresponding strategies, a two-group three-dimensional transient neutron code (SMART) is adopted to study the physical process of reactor trip test. The effects of initial core state parameters on ΔI evolution during reactor trip are studied. And it is concluded that the initial ΔI and R bank position are the main factors affecting the extreme value of ΔI in the process of reactor trip. To avoid unnecessary overpower ΔT triggering in reactor trip test, a xenon oscillation method is proposed and proved to be effective according to SMART’s simulation results.

Research on Calculation Method and Additionality of Carbon Emission Reduction of Nuclear Energy Heating Based on Project Perspective
Authors: Lu Chunhua , An Changle , Sun Quantuo , Li Zhe 
Published: April 2023

AbstractNuclear energy has broad prospects for development driven by the goal of achieving peak carbon emissions and carbon neutrality, but the independent contribution of nuclear energy in low-carbon development has not obtained corresponding economic benefits. Studying the so-called “economic dilemma” problem of nuclear energy heating projects in the face of carbon trading market will reveal the influencing factors of this problem, and provide a method and paradigm reference for nuclear energy heating projects, that is, through active participation Carbon emissions trading to improve economics. This paper establishes a project-based calculation method for carbon emission reductions of nuclear energy heating, and conducts a systematic additionality analysis by taking a nuclear heating project in Shandong, China as an example. The method follows the principles of the Clean Development Mechanism (CDM) and the Chinese Certified Emission Reduction (CCER). The findings show that: (1) The carbon emission reduction of nuclear energy extraction and heating projects in Shandong region of China is about 274,100 tons/year, and its order of magnitude is highly suitable for carbon market demand. (2) The levelized heating cost of the case is about 49.20 yuan/GJ. Through the analysis of the change of coal price in the calculation parameters of the alternative scheme, it is found that the economics of the nuclear energy heating project is seriously affected by the “baseline” and the results of parameter selection. It is very easy to create the illusion that the levelized heating cost of the nuclear extraction steam heating project is higher than the “uneconomical” illusion of the alternative. (3) The empirical analysis results show that the nuclear energy heating project has the additionality of obtaining carbon emission reduction benefits, but when the economics of the nuclear energy project has no obvious disadvantage compared with the alternative, its demonstration should focus on analyzing its advanced technology, barriers to marketing. As the emission reductions of CCER projects are consumed year by year in a stagnant state, nuclear energy heating projects will have the opportunity to provide a stable supply of voluntary certified emission reductions for China’s carbon market. Finally, based on this research, some suggestions are put forward, such as building a data monitoring and statistical system for carbon emission reduction of nuclear energy projects, and a pilot project for the transformation of economic benefits of carbon emission reduction in nuclear energy projects.
Research of Corrosion Products Migration Behavior in PWR Primary Circuit Under Extended Low Power Operation Mode

Published: April 2023

AbstractIn order to improve the flexibility of response to power grid demand, both newly built and in-service nuclear power units need to demonstrate the feasibility of ELPO (Extended Low Power Operation) and design schemes. During ELPO, the change of local thermal hydraulic conditions caused by the change of core power will have a great impact on the migration behavior of corrosion products in the primary circuit of PWR (Pressurized Water Reactor). Corrosion products deposited in the core will affect the heat transfer of fuel cladding, axial power distribution and critical heat flux. Corrosion products deposited outside the reactor, such as the main tubes, will affect the dose rate of personnel and pose challenges to radiation protection. A model for simulating the migration of corrosion products in the primary circuit of a PWR was established. The variation trends of the total amount of fuel CRUD (Chalk Rivers Unidentified Deposit), the total amount of fouling outside the reactor, the removal amount of corrosion products, the coolant source term and the main tubes deposition source term of a PWR before and after ELPO were compared. The results show that ELPO mode can inhibit the deposition of corrosion products in the core, and make more corrosion products deposit outside the core or be removed by CVCS (Chemical and Volume Control System). Because ELPO mode accelerates the migration of activated corrosion products to other regions, the coolant source term increases slightly. For the source term of main tubes sediment, ELPO model can reduce its total activity, thus reducing the personnel dose rate.

Authors: Wan Haixia 
Published: April 2023

AbstractIn the coolant system of lead-bismuth fast reactor, the corrosion products produce great occupational radiation dose to the workers, especially in the process of maintenance and repair of nuclear facilities. Therefore, it is very important to accurately calculate the corrosion product source term caused by the reaction between coolant and structural materials. The generation, migration, decay and deposition of corrosion products are described by the corrosion characteristics of lead-bismuth alloy on stainless steel in coolant loop, and the mathematical equilibrium equation is established. The equation is used to calculate the corrosion product source term of the coolant loop in the 20MWth lead-bismuth fast reactor and the variation laws of the corrosion product with time are obtained. The results show that the radioactivity of the corrosion products mainly comes from nuclides such as 51Cr, 54Mn, 58Co and 60Co, and the short-lived nuclides such as 51Cr and 58Co decay gradually after shutdown, long-lived nuclides such as 54Mn and 60Co are the main sources of radioactivity.

Published: April 2023

AbstractOperating conditions in the liquid metal fast reactor, like higher power density, higher temperature gradient, and higher burnup, are more severe to the fuel rod comparing to the light water reactor. The integrity and safety of the fuel rod is very essential to the reactor safety. In this study, the fuel rod designed for M2LFR-1000, which is a typical pool type lead cooled fast reactor, is evaluated using a fuel performance analysis code named KMC-Fueltra. Irradiation behaviors and material properties for the MOX fuel and T91 cladding are established and introduced into the code. The steady-state performance of the fuel rod is analyzed. Results concerning both fuel and cladding performance are discussed based on indicative design limits collected from the open literatures. This study is useful to improve the conceptual design of the M2LFR-1000.

Published: April 2023

AbstractDuring the operation of the floating nuclear power plant, if the floating nuclear power plant is anchored near the shore for power generation, it may be impacted by runaway ships. If the impact causes damage to the tank of the floating nuclear power plant and water inflow, and even damage to the containment structure, it will seriously threaten the structural safety of the floating nuclear power plant and even threaten nuclear safety. This paper uses the explicit dynamics method to establish two models of dry/wet impact. It assumes that the 5000T container ship will laterally impact the reactor compartment of the floating nuclear power plant at a speed of 2 m/s, and the effects of the fluid domain (water and air domain) are ignored/counted in the calculation process. Then, comparing the effects of the above two models of dry/wet impact on the calculation duration, the damage and water ingress state of the floating nuclear power plant, the stress of the steel containment (including support). Studies have shown that if the relevant personnel do not need to understand the effect of water intrusion into the damaged cabin, the influence of water and air domain on the impact simulation results can be ignored, and the dry model can be directly used for calculation.
