Abstract
In addressing the problem of low prediction accuracy in the remaining useful life (RUL) prediction of rolling bearings, caused by noise interference and insufficient extraction of sensitive features by deep learning models, this paper presents a life prediction method based on signal reconstruction and dual-channel network fusion. First, addressing the issue of extracting weak features from rolling bearing vibration signals, an optimized combination of variational mode decomposition (VMD) and Teager–Kaiser energy operator (TKEO) for signal reconstruction is proposed. TKEO is used to track the energy of high-frequency impulses in the original signal. The sparrow search algorithm is employed for optimizing VMD to perform high-frequency filtering, resulting in an optimized impulse energy signal. This signal is then multiplied with the original signal to enhance weak impulse features under noisy background. Next, a dual-channel network model for RUL prediction is constructed based on temporal convolutional network (TCN) and convolutional neural networks (CNNs). The one-dimensional time-series signal obtained after reconstruction and denoising serves as the input for the TCN network channel. Simultaneously, the signal obtained after reconstruction and denoising undergoes synchrosqueezed wavelet transforms to generate a two-dimensional time–frequency representation as input for the CNN network channel. This setup allows TCN and CNN to respectively extract temporal features from the vibration signal and time–frequency features from the spectrogram. By incorporating self-attention mechanisms, internal correlations between different features are fully explored, thereby enhancing prediction accuracy.

Abstract
Boron (B) powder injection is a potential alternative to glow discharge boronization as a wall conditioning method for tokamaks. This technique is currently being studied in WEST experiments, during which B powder is injected by an Impurity Powder Dropper developed by PPPL. In order to interpret and analyse experimental trends, and to help develop future experiments, a modelling workflow using a boundary plasma simulation (SOLEDGE-EIRENE) and powder ablation simulation (Dust Injection Simulator) was developed and tested. The effect of adding a B neutral source to simulated deuterium + oxygen (D + O) plasmas was compared to experimental data from the WEST C5 campaign, where B powder was injected in a dedicated experiment. While the impact of B injection on radiated power

and O-II line intensity at the lower divertor between experiment and simulation. This discrepancy suggests that those parameters were affected by phenomena not present in the simulations, with the most likely candidates being reduced D recycling and a reduced O sourcing from the divertor.

Abstract
Underground compressed air energy storage (CAES) is seen as an important and promising way for balancing electrical power system. Many large-scale CAES projects (≥300 MW) are being planned in China, some of which have already been permitted for construction. Despite the benefits from CAES, some challenges arise in area of construction technology, operation system, maintenance and monitoring methods. One of the challenges lies in the evaluation of air leakage effect on flow and stress field around the underground cavern. Therefore, considering the actual physical field characteristics, the mathematical formula of mass conservation equations for air and water in porous media, as well as equilibrium equations for solid mechanics are established first and then coupled together for numerical solutions. The constitutive models for solid and porous fluid adopt classical elastic and Darcy’s law respectively, while the air-water interaction adopts classical van-Genuchten model and contributes to solid mechanics by pore pressure. Numerical implementations are based on secondary development to COMSOL software. Then interpretations to simulation results and the comparison with results not taking damage effect into account are made.
A Phase Field Crystal Method for Multilayer Graphene
Authors: Liu Kai 
Published: October 2023

Abstract
Bilayer graphene has been a subject of intense study in recent years. We extend a structural phase field crystal method to include an external potential from adjacent layer(s), which is generated by the corresponding phase field and changes over time. Moreover, multiple layers can be added into the structure. Using the thickness of the boundaries between different stacking variants of the bilayer structure as the key parameter, we quantify the strength of the adjacent layer potential by comparing it with atomistic simulation results. Then, we test the multiple graphene structures, including bilayers, triple layers, and up to 6 layers. We find that in addition to the initial conditions, the manner in which new layers are added into the structure affects the layout of the atomic configuration. Finally, we simulate the case of twisted stacking bilayer graphene under the “magic angle 1.1° ”, and our results help identify the key physical ingredients to predict what relaxations may occur.

Abstract
Based on PYTHON, a mesoscale model of multi-interface recycled brick concrete was constructed by ABAQUS. The concrete consists of seven-phase inhomogeneous composites, including waste brick, waste concrete, old and new mortar, waste brick-new mortar, aggregate-old mortar, and new-old mortar. The numerical model was established by considering different aggregate placement rates and brick amounts, with a coarse aggregate placement rate of 45%. Computational analysis of the fine-scale mechanical properties was completed, and the damage mode of the recycled concrete containing bricks under the load was investigated. The study showed that the peak stress and elastic modulus of recycled brick concrete decreased gradually with an increase in brick quantity, and the peak strain of recycled brick concrete increased with an increase in brick quantity. However, the damage pattern of concrete with different brick quantities was basically the same.

Abstract
Ship collisions are prevalent every year, leading to significant maritime traffic accidents. This paper presents research on dynamic path planning and tracking control for ship collision avoidance by integrating ship automatic avoidance technology to address this issue. We conducted a comprehensive study on artificial potential fields, trajectory tracking, and route trajectory tracking in response to the current state of ship collision avoidance and trajectory tracking. The study employed vector decomposition and slider control as research methods to analyze, optimize, and modify ship collision avoidance methods. Additionally, we carried out collision avoidance simulations using MATLAB to verify the stability and safety of ship trajectory tracking under various methods to advance the research on ship collision avoidance and trajectory. The proposed approach has the potential to significantly reduce ship collisions and enhance ship trajectory safety.

Abstract
This study presents a novel adjustable device designed for precise frequency tuning within the S-band of the microwave spectra. In addition to the geometrical design and dielectric behavior of the resonator, this study identifies an influential governing factor that affects the resonant frequency. The proposed method utilizes a bi-layer split ring resonator configuration implemented on a

FR4 epoxy substrate with a dielectric constant of 4.4. The substrate is coated with a 35 μm- thick layer of copper and patterned as split ring resonator. Frequency tuning was achieved by spatially separating the two parallel split ring resonators in increments of 800 μm. This innovative approach allows for a shift in the resonant frequency range from 2.36 GHz to 2.61 GHz, covering the desired frequencies in the S-band for applications such as biomedical and wireless communications. This study demonstrates that the alteration in the frequency domain is dependent on the distance between the two layers of split ring resonators. Compared to existing frequency tuning mechanisms, this adjustable bi-layer split ring resonator offers numerous advantages including simplicity, cost-effectiveness, and high sensitivity. The research employs a combination of finite-element simulations and theoretical analysis to validate the findings.

Abstract
Evolutionary biologists recognize that understanding the phylogenetic history of closely related species is challenging without considering their population genetics history. The taxonomy of Magnolia sect. Talauma in Cuba has long been debated, with several changes in taxon delimitations. All these taxonomic revisions were based exclusively on leaf morphological characteristics of a few individuals, limiting their ability to elucidate taxon boundaries. Recent studies have focused on conservation genetics and species delimitation of Cuban magnolias, based on ecological, morphological and genetic data. Here, we use full plastome sequences and microsatellite data to infer phylogenetic relationships and potential historical migration events among species in Magnolia sect. Talauma in Cuba. Bayesian phylogeny and TreeMix were used to understand the phylogenetic relationships. Based on this, Magnolia sect. Talauma in Cuba does not comprise a monophyletic group. The data continue to show a highly supported unresolved species complex in the taxa of Magnolia subsect. Talauma from north-eastern Cuba. From a taxonomic point of view, our results do not entirely support the most recent taxonomic review proposed for the family in Cuba.

Abstract

Aims
Contemporary guidelines differ in their recommendations regarding initiating non-vitamin K antagonist oral anticoagulants (NOACs) in patients with atrial fibrillation (AF) at low risk of stroke. This study aimed to examine the effectiveness and safety of NOACs for low-risk AF in a Japanese cohort.

Methods and results
In this retrospective cohort study based on the JMDC Claims Database extracted between April 2011 and November 2022, we identified 13 291 patients with AF at low risk of stroke. We performed inverse probability of treatment weighting Cox regression analyses to compare the embolization and bleeding risks between the nontreatment and NOAC groups. Net clinical benefit was defined as the annual incidence of ischaemic stroke events prevented by NOACs after subtracting intracranial haemorrhage (ICH) events attributable to NOACs, multiplied by a weighting factor. The incidences of stroke and ICH in the nontreatment group were 0.47 and 0.15 per 100 person-years, respectively. The NOAC group had higher incidences of ICH (hazard ratio [HR]: 1.73, 95% confidence interval [CI]: 0.75–4.00) and stroke (HR: 1.41, 95% CI: 0.84–2.36). The net clinical benefit of NOAC treatment was −0.35% per year (95% CI: −0.99–0.29%).

Conclusion
Non-vitamin K antagonist oral anticoagulants treatment may be associated with a slightly high risk of ICH, and it yielded a neutral clinical benefit in the present Japanese population, which provides reassurance concerning the role of ethnicity in NOAC treatment for patients with AF and suggests a need to assess comprehensive weighting of the respective risk factors.

Abstract

Aims
To estimate sick leave (SL) duration after first-time elective open-heart surgery and identify factors contributing to increased SL.

Methods and results
A retrospective nationwide cohort study combined data from the Norwegian Register for Cardiac Surgery and SL data from the Norwegian Labour and Welfare Administrations. All able-bodied adults who underwent first-time elective open-heart surgery in Norway between 2012 and 2021 were followed until 1 year after surgery. The impact of socio-demographic and clinical factors on SL after surgery was analysed using logistic regression and odds ratios. Of 5456 patients, 1643 (30.1%), 1798 (33.0%), 971 (17.8%), 1035 (18.9%), and 9 (0.2%) had SL of &lt;3, 3–6, 6–9, and 9–12 months, and 1 year, respectively. SL &gt;6 months was associated with female gender, primary education only, and average annual income. Post-operative stroke, post-operative renal failure, New York Heart Association Functional Classification system (NYHA) score &gt;3, earlier myocardial infarction, and diabetes mellitus increased the odds of SL &gt;6 months.

Conclusion
This study demonstrates that socio-demographic and clinical factors impact SL after first-time elective open-heart surgery. Patients who experience a stroke or develop renal failure after surgery have the highest odds of SL &gt;6 months. Females and patients with low education levels, earlier myocardial infarction, or NYHA scores III–IV have a two-fold chance of SL &gt;6 months. The findings allow for future investigations of pre- and post-surgery interventions that can most effectively reduce SL and aid return to work.
What is missing from how we measure and understand the experience of poverty and deprivation in population health analyses?
Authors: Timpson Katharine , McCartney Gerry , Walsh David , Chabanis Berengere 
Published: October 2023

Abstract

Background
Explaining why some populations are healthier than others is a core task of epidemiology. Socioeconomic position (SEP), encompassing a broad range of exposures relating to economic circumstances, social class and deprivation, is an important explanation, but lacks a comprehensive framework for understanding the range of relevant exposures it encompasses.

Methods
We reviewed existing literature on experiential accounts of poverty through database searching and the identification of relevant material by experts. We mapped relevant concepts into a complex systems diagram. We developed this diagram through a process of consultation with academic experts and experts with direct experience of poverty. Finally, we categorized concepts on the basis of whether they have previously been measured, their importance to the causal flow of the diagram, and their importance to those consulted, creating a list of priorities for future measurement.

Results
There are a great many aspects of SEP which are not frequently measured or used in epidemiological research and, for some of these, work is needed to better conceptualize and develop measures. Potentially important missing aspects include stigma, social class processes, access to education, sense of lost potential, neighbourhoods, fairness and justice, emotional labour, masking poverty, being (in)visible, costs, and experiences of power.

Conclusions
Analyses seeking to understand the extent to which SEP exposures explain differences in the health of populations are likely to benefit from a comprehensive understanding of the range and inter-relationships between different aspects of SEP. More research to better conceptualize and measure these aspects is now needed.
MyeloidmiR-155plays a limited role in antibacterial defense duringKlebsiella-derived pneumosepsis and is dispensable for lipopolysaccharide- orKlebsiella-induced inflammation in mice

Published: October 2023

AbstractMicroRNA-155 (miR-155) plays a crucial role in regulating host inflammatory responses during bacterial infection. Previous studies have shown that constitutive miR-155 deficiency alleviates inflammation while having varying effects in different bacterial infection models. However, whether miR-155 in myeloid cells is involved in the regulation of inflammatory and antibacterial responses is largely elusive. Mice with myeloid cell specific miR-155 deficiency were generated to study the in vitro response of bone marrow-derived macrophages (BMDMs), alveolar macrophages (AMs) and peritoneal macrophages (PMs) to lipopolysaccharide (LPS), and the in vivo response after intranasal or intraperitoneal challenge with LPS or infection with Klebsiella (K.) pneumoniae via the airways. MiR-155-deficient macrophages released less inflammatory cytokines than control macrophages upon stimulation with LPS in vitro. However, the in vivo inflammatory cytokine response to LPS or K. pneumoniae was not affected by myeloid miR-155 deficiency. Moreover, bacterial outgrowth in the lungs was not altered in myeloid miR-155-deficient mice, but Klebsiella loads in the liver of these mice were significantly higher than in control mice. These data argue against a major role for myeloid miR-155 in host inflammatory responses during LPS-induced inflammation and K. pneumoniae-induced pneumosepsis but suggest that myeloid miR-155 contributes to host defense against Klebsiella infection in the liver.
Reproductive biology of the red swamp crayfish Procambarus clarkii (Girard, 1852) (Decapoda: Astacidea: Cambaridae): A review
Authors: Hamasaki Katsuyuki , Dan Shigeki , Kawai Tadashi 
Published: October 2023

Abstract
The red swamp crayfish Procambarus clarkii (Girard, 1852) is an alien invasive species as well as a commercially exploited animal. The sterile-male-release technique (SMRT) using infertile but sexually active males has been an effective candidate measure to control this invasive crayfish. Additionally, the limited supply of juveniles due to females’ spawning seasonality hinders the further development of the P. clarkii aquaculture industry. Information on its reproductive biology, such mating strategies and factors affecting offspring production, is crucial for developing an effective SMRT and aquaculture systems for P. clarkii. We review the reproductive biology of this species in terms of 1) sexual dimorphism and reproductive status, 2) sex recognition, mating, and mate preferences, and 3) egg production, embryonic development, and hatching. Intra- and intersexual dimorphisms of chelae are evident in P. clarkii, and a reproductive morphotype (form I) with larger chelae and a non-reproductive morphotype (form II) with smaller chelae are detected in both females and males, allowing us to easily determine the reproductive status of both sexes. The crayfish exhibits mutual mate choice (i.e., preference for larger mates), and small-sized males reproductive potential is low. Female fitness (i.e., number of offspring) generally depends on their body size. Female brood care appears to promote early embryo development before the egg-nauplius stage. Further study is required to identify the maternal factors affecting early embryonic development, which may improve measures for controlling invasive populations and enhancing aquaculture productivity.
Reinstrumentation for progressive hyper-kyphotic deformity after implant removal despite obtaining physiological alignment by posterior corrective surgery for adolescent idiopathic scoliosis with flat back: a case report
Authors: Toga Akira , Fukuda Kentaro , Ozaki Masahiro , Fujii Takeshi , Yonezawa Yoshiro 
Published: October 2023

Abstract
This case report describes a 13-year-old female patient with adolescent idiopathic scoliosis (AIS) and flat back who experienced progressive kyphotic deformity after implant removal despite obtaining physiological alignment postoperatively. The patient underwent multiple surgeries, and a late-developing infection complicated her treatment course. Despite hard bracing to prevent kyphotic change, the kyphosis progressed to 74° within a year after implant removal, leading to a decrease in patient height and back pain. Revision surgery was eventually necessary. Possible factors for the kyphotic progression include injury to paraspinal back muscles due to multiple surgeries or insufficient bony fusion from late-developing infection. This case highlights the importance of thorough evaluation and follow-up for optimal patient outcomes after implant removal in AIS patients, particularly those with flat back.

Published: October 2023

Abstract
Words are essential parts for understanding classical Chinese poems. We report a collection of 32,399 classical Chinese poems that were annotated with word boundaries. Statistics about the annotated poems support a few heuristic experiences, including the patterns of lines and a practice for the parallel structures (對仗), that researchers of Chinese literature discuss in the literature. The annotators were affiliated with two universities, so they could annotate the poems as independently as possible. Results of an inter-rater agreement study indicate that the annotators have consensus over the identified words 93 per cent of the time and have perfect consensus for the segmentation of a poem 42 per cent of the time. We applied unsupervised classification methods to annotate the poems in several different settings, and evaluated the results with human annotations. Under favorable conditions, the classifier identified about 88 per cent of the words, and segmented poems perfectly 22 per cent of the time.
