AbstractThe Ilkurlka structure is an ~12 km diameter buried circular aeromagnetic anomaly within the Officer Basin in Western Australia. Prior studies postulated a range of origins, including meteorite impact. We report the presence of pervasive deformation in the first drill cores from the structure. Brecciated sandstone and siltstone contain arrays of quartz grains with concussion fractures and rare shocked quartz grains with planar deformation features (PDF). Universal stage measurements of two quartz grains reveal one grain with PDF parallel to (0001) orientation and three PDF sets parallel to . A second grain contains three PDF sets parallel to and one set parallel to . The shocked grains are interpreted to have formed in situ, rather than representing transported detrital shocked grains. These results suggest local shock compression of at least 10 GPa; however, preservation of primary porosity and overall paucity of shocked grains may indicate lower mean shock pressures. (U‐Th)/He dating of 58 apatite grains from four samples across both cores shows a dominant age population at ~265 Ma and a minor age population at ~135 Ma. These dates overlap with regional events and thus do not provide an unambiguous impact age. An upper Carboniferous to lower Permian maximum impact age is provisionally proposed based on inferred missing target rock stratigraphy.

AbstractThe annual flooding cycle of Amazonian rivers sustains the largest floodplains on Earth, which harbour a unique bird community. Recent studies suggest that habitat specialization drove different patterns of population structure and gene flow in floodplain birds. However, the lack of a direct estimate of habitat affinity prevents a proper test of its effects on population histories. In this work, we used occurrence data, satellite images and genomic data (ultra‐conserved elements) from 24 bird species specialized on a variety of seasonally flooded environments to classify habitat affinities and test its influence on evolutionary histories of Amazonian floodplain birds. We demonstrate that birds with higher specialization in river islands and dynamic environments have gone through more recent demographic expansion and currently have less genetic diversity than floodplain generalist birds. Our results indicate that there is an intrinsic relationship between habitat affinity and environmental dynamics, influencing patterns of population structure, demographic history and genetic diversity. Within the floodplains, historical landscape changes have had more severe impacts on island specialists, making them more vulnerable to current and future anthropogenic changes, as those imposed by hydroelectric dams in the Amazon Basin.

AbstractBackgroundRecently, a new OCTARAY® mapping catheter was commercially launched. The catheter is designed to enable high‐density mapping and precise signal recording via 48 small electrodes arranged on eight radiating splines. The purpose of this study was to compare bipolar voltage and low‐voltage‐area size, and mapping efficacy between the OCTARAY catheter and the PENTARAY® catheterMethodsTwelve consecutive patients who underwent initial and second ablations for persistent atrial fibrillation within 2 years were considered for enrollment. Voltage mapping was performed twice, first during the initial ablation using the PENTARY catheter and second during the second ablation using the OCTARAY Long 3‐3‐3‐3‐3 (L3) catheter.ResultsMean voltage with the OCTARAY‐L3 catheter (1.64 ± 0.57 mV) was 32.3% greater than that with the PENTARAY catheter (1.24 ± 0.46 mV, p < .0001) in total left atrium. Low‐voltage‐area (<0.50 mV) size with the OCTARAY‐L3 catheter was smaller than that with the PENTARAY catheter (6.9 ± 9.7 vs. 11.4 ± 13.0 cm2, p < .0001). The OCTARAY‐L3 catheter demonstrated greater efficacy than the PENTARAY catheter in terms of shorter mapping time (606 ± 99 vs. 782 ± 211 s, p = .008) and more mapping points (3,026 ± 838 vs. 781 ± 342 points, p < .0001).ConclusionThe OCTARAY catheter demonstrated higher voltage recordings, narrower low‐voltage areas, and a more efficacious mapping procedure than the PENTARAY catheter.

Published: November 2023

AbstractObjectiveTo enable the intelligent diagnosis of a variety of common Electrocardiogram (ECG), we investigate the deep learning‐based ECG diagnosis system.MethodsFrom January 2015 to December 2019, four consecutive years of 100,120 conventional 12‐lead ECG data were collected in our hospital. Utilizing this dataset, we constructed a deep learning model designed to intelligently diagnose prevalent ECG anomalies by employing a multi‐task learning framework. The system performance was evaluated using various metrics, including sensitivity, specificity, negative predictive value, positive predictive value, and so forth. Additionally, we employed an ECG intelligent diagnostic platform for clinical application to undertake real‐time online analysis of 2500 conventional 12‐lead ECG samples in June 2020, aiming to validate our model. At this stage, we compared the performance of our model against the traditional manual identification method.ResultsThe efficacy of the ECG intelligent diagnostic model was notably high for common and straightforward ECG patterns, such as sinus rhythm (F1 = 98.01%), sinus tachycardia (F1 = 96.26%), sinus bradycardia (F1 = 94.88%), and a normal electrocardiogram (F1 = 91.71%), as well as for Premature Ventricular Contractions (F1 = 91.62%). Nevertheless, when diagnosing rarer and more intricate ECG anomalies, the system requires an increased number of samples to refine the deep learning models. During the validation stage, our model exhibited better efficiency in terms of accuracy, labor time and labor cost when compared to the manual identification approach.ConclusionsOur deep learning‐driven intelligent ECG diagnostic model clearly demonstrates significant clinical utility. The integrated artificial intelligence diagnosis system not only has the potential to augment physicians in their diagnostic processes but also offers a viable avenue to reduce associated labor costs.

AbstractWe describe a case of congenital syphilis in an adopted infant with a unique dermatologic presentation of scalp granulomas, along with lymphadenopathy, anemia, and elevated liver transaminases. To our knowledge, this cutaneous morphology has not been previously reported in the literature. This case highlights the varied clinical presentation of congenital syphilis and the diagnostic challenge it poses for clinicians, especially in the context of unknown prenatal history/unknown risk factors, or if syphilis is acquired during pregnancy after routine screening is performed. As the incidence of congenital syphilis has more than tripled in recent years, this diagnosis should be considered when a neonate or infant presents with unexplained skin nodules.

SUMMARYPlant NAC transcription factors play a crucial role in enhancing cold stress tolerance, yet the precise molecular mechanisms underlying cold stress remain elusive. In this study, we identified and characterized CaNAC035, an NAC transcription factor isolated from pepper (Capsicum annuum) leaves. We observed that the expression of the CaNAC035 gene is induced by both cold and abscisic acid (ABA) treatments, and we elucidated its positive regulatory role in cold stress tolerance. Overexpression of CaNAC035 resulted in enhanced cold stress tolerance, while knockdown of CaNAC035 significantly reduced resistance to cold stress. Additionally, we discovered that CaSnRK2.4, a SnRK2 protein, plays an essential role in cold tolerance. In this study, we demonstrated that CaSnRK2.4 physically interacts with and phosphorylates CaNAC035 both in vitro and in vivo. Moreover, the expression of two ABA biosynthesis‐related genes, CaAAO3 and CaNCED3, was significantly upregulated in the CaNAC035‐overexpressing transgenic pepper lines. Yeast one‐hybrid, Dual Luciferase, and electrophoretic mobility shift assays provided evidence that CaNAC035 binds to the promoter regions of both CaAAO3 and CaNCED3 in vivo and in vitro. Notably, treatment of transgenic pepper with 50 μm Fluridone (Flu) enhanced cold tolerance, while the exogenous application of ABA at a concentration of 10 μm noticeably reduced cold tolerance in the virus‐induced gene silencing line. Overall, our findings highlight the involvement of CaNAC035 in the cold response of pepper and provide valuable insights into the molecular mechanisms underlying cold tolerance. These results offer promising prospects for molecular breeding strategies aimed at improving cold tolerance in pepper and other crops.

AbstractAimsWithin the One Health paradigm, infectious disease surveillance have been developed for domestic and wild animals, leaving the role of captive non‐domestic populations, especially felids in zoos and circuses, less explored. This study addresses the proximity of these captive animals to urban areas, necessitating focused monitoring for potential zoonotic enteropathogens. The present work aimed to investigate the presence of such zoonotic enteropathogens in faecal samples from captive large felid populations.Methods and ResultsA total of 108 faecal samples were collected in three circuses, five zoos and one rescue centre across Italy. Salmonella spp. isolation, serotyping and antimicrobial susceptibility testing were conducted on all samples. Additionally, 60 samples were also examined for gastrointestinal parasites using standard coprological techniques. Giardia spp. detection employed direct immunofluorescent staining and specific PCR, while Toxoplasma gondii was detected using PCR targeting B1 gene. A total of 51 Salmonella enterica subsp. enterica were isolated, with predominant serovariants including Infantis (43.1%), Coeln (11.8%) and Newport (11.8%). The captive felids likely act as asymptomatic carriers of foodborne Salmonella, with notable resistance ampicillin and trimethoprim‐sulfamethoxazole, no resistance to enrofloxacin was noted. Microscopic analysis revealed Toxascaris leonina eggs in 11 faecal samples (18.3%) and Giardia duodenalis cysts in one animal (1.7%).ConclusionsCaptive animals in public settings may act as sources of Salmonella infection and enteroparasitosis for both occupational and general exposure. The study emphasizes the role of captive animals in antimicrobial resistance dynamics, highlighting the need for routine pathogen screening in the management practices of zoological structures.

Authors: Takahashi Junya , Yamaguchi Atsushi 
Published: November 2023

Abstract
To promote the application of Fitness-For-Service (FFS) in Japanese industry, the Japan Welding Engineering Society (JWES) published WES 2820:2015 as an FFS assessment procedure specifically applicable to metal loss. In this study, the outline and concepts of WES 2820 are described. The metal loss assessment presented in WES 2820 adopts the technical bases of Part 4 (general metal loss assessment) and 5 (local metal loss assessment) of the API 579-1/ASME FFS-1 standard, which have gained worldwide acceptance. In WES 2820, the two different methods for general and local metal loss assessment are implemented as a single assessment procedure. The assessment procedure is simplified and focuses on its ease-ofuse in on-site applications. Moreover, WES 2820 has a high affinity with the WES 7700 series of welding repair codes, also published by the JWES. Therefore, the necessity for welding repair based on the WES 7700 procedure can be confirmed by the application of WES 2820. In addition, WES 2820 provides example problems for confirming a user’s understanding and improving convenient application. Revisions to the WES 2820 consider the latest techniques and present additional examples to further improve rational assessment and convenience for the user. Additionally, this study introduces an actual case study of the application of WES 2820.

Published: November 2023

Abstract
Cryogenic gases such as Liquefied Natural Gas (LNG) or Liquefied Hydrogen (LH2) establish themselves as important energy carriers in the transport sector. Its storage requires tanks with Thermal Super Insulations (TSI) to keep the transported fluid cold. TSI has already proven itself in various applications over a long time, but not in the land transport sector, where accidents involving collisions, fires, and their combination are to be expected. The focus of this study was to investigate the behavior of a TSI exposed to a heat source that represents a fire. For this purpose, a High-Temperature Thermal Vacuum Chamber (HTTVC) has been developed that allows the thermal loading of a TSI and simultaneous measurement of heat flow through this TSI. The HTTVC was applied to investigate TSI based on Multilayer Insulations (MLI) and vacuum. The thermal exposure caused permanent damage to the sample. In practice, this can lead to a rapid release of flammable gas as well as a Boiling Liquid Expanding Vapour Explosion (BLEVE). The results are relevant for the evaluation of accident scenarios, the improvement of TSI, and the development of emergency measures.
Development of Prediction Tool for Flow-Accelerated Corrosion: (2) Evaluation of Geometry Factor for Various Pipe Components

Published: November 2023

Abstract
Pipe wall thinning is an important issue in the maintenance of power plants. In particular, flow-accelerated corrosion (FAC) in carbon steel pipelines requires continuous monitoring because of its potential to cause catastrophic pipe rupture. In Japan, management rules for pipe wall thinning in power plants were established after the Mihama accident in 2004 based on pipe wall thickness measurements. However, this monitoring may lead to a large number of measurements for each outage in the power plants. In addition, because this approach assumes constant operating condition, some issues may occur when the plant operating conditions change and a decrease or increase in the FAC rate is expected. For the future improvement of pipe wall thinning management in Japanese power plants, the introduction of prediction methods or prediction codes for thinning rate and residual lifetime evaluation is expected, as already introduced in many other countries. Therefore, the authors conducted research to develop prediction methods for pipe wall thinning management for use in domestic power plants.
In this study, to easily apply the FAC prediction model under single-phase water conditions to the actual piping system of nuclear power plants in Japan, we evaluated the geometry effect and the piping layout effect for the various piping components based on CFD parameter analysis. From the CFD results, the influence of the mass transfer coefficient on the parameters of the piping components such as the beta ratio of the orifice was evaluated. An original correlation was developed to enable prediction for the piping system of the actual plants, which consists of the various piping components.
Multi-Axial Stress Creep Consumption Part II; Consideration on Creep Criteria Temperature for FFS
Authors: Ishizaki Yoichi , Suzuki Teppei 
Published: November 2023

Abstract
A cracking damage was found in 347SS flange neck operated at about 520 deg.C after long term operation. In previous report presented in PVP2019-9304, it was well explained by creep damage from FEM analysis using isochronous curve based on API 579/ASME FFS-1 MPC Omega method. Following our previous paper, specimens were obtained from the replaced flange operated for 4 years. Using those specimens, destructive testing and remaining life assessment were performed to validate the analysis.
As a result, specimens from the flange neck showed relatively short rupture life, compared to those from other locations. MPC Omega method along with adjustment factors derived from testing resulted in remaining life of 3.1 to 6.8 × 105 hrs. at average operating condition. In consideration with temperature variation during operation, remaining life is estimated to be 2.6 × 10-5 hrs., indicating 10 % life consumption at the time of taking sample. Life consumption estimated by FEM analysis is rather conservative but is comparable within factor of 2 when average strength is applied for the evaluation.
Since the estimated stress conditions and test conditions are close to 0.2% proof stress of the material at this temperature range, significant primary creep strain was observed in the tests, that can cause some conservativeness in remaining life by the FEM analysis.
While above, Larson Miller Parameter method also adjusted with rupture test data agrees with MPC Omega method on the assumption of uniaxial tension. However, it gives less-conservative life under the multiaxial stress conditions. Effect of multiaxial stress on creep life is more significantly observed in MPC Omega method, especially when stress ratio is higher.
In part I of two papers, the detail of creep test was presented and discussed. In this part II, current creep temperature limit shown in API579-1/ASME FFS-1 Part 4 Table 4.1 will be discussed and suggest an upgrade of creep temperature criteria for metal loss FFS based on the multi-axial creep model we learned through studies.
Estimation of Load Bearing Capacity in 3D Printed PLA Notched Plates Using the Theory of Critical Distances
Authors: Cicero Sergio , Arrieta Sergio , Sánchez Marcos 
Published: November 2023

Abstract
This paper provides a simple safe approach to obtain estimations of the load-bearing capacity of 3D printed PLA (polylactic acid) plates containing U-notches. The plates are subjected to pure tensile loading and combine different types of notch lengths. The estimations are obtained defining the stress field ahead of the notch tip by the Creager-Paris stress distribution, and establishing the fracture criterion through the Theory of Critical Distances (TCD). This theory requires an additional material parameter, the critical distance (L), to determine failure conditions. Particularly, in fracture evaluations, the TCD provides several failure criteria, among which the Point Method (PM) is particularly simple and has been validated in a number of more conventional materials, such as structural steels, aluminum alloys, different types of polymers and composites. The PM states that fracture occurs when the stress level reaches the inherent strength (σ0) at a distance from the notch tip equal to L/2. L and σ0 are related to each other through the material fracture toughness (Kc), so σ0 is not an additional (second) parameter required for the assessments. In any case, the results obtained in the present work demonstrate the capacity of the proposed methodology for estimating the load-bearing capacity in this specific 3D printed material and for the component geometry and loading conditions analyzed here, which implies low constraint conditions, providing safe reasonably conservative predictions.
Fatigue and Fracture Behavior of Vintage Pipelines in Gaseous Hydrogen Environment

Published: November 2023

Abstract
There is a global interest in decarbonizing the existing natural gas infrastructure by blending the natural gas with hydrogen. However, hydrogen is known to embrittle pipeline and pressure vessel steels used in gas transportation and storage applications. Thus, assessing the structural integrity of vintage pipeline (pre-1970s) in the presence of gaseous hydrogen is a critical step towards successful implementation of hydrogen blending into existing infrastructure. To this end, fatigue crack growth (FCG) behavior and fracture resistance of several vintage X52 pipeline steels were evaluated in high purity gaseous hydrogen environments at pressure of 210 bar (3,000 psi) and 34 bar (500 psi). The base metal and seam weld microstructures were characterized using optical microscopy, scanning electron microscopy (SEM) and Vickers hardness mapping. The base metals consisted of ferrite-pearlite banded microstructures, whereas the weld regions contained ferrite and martensite. In one case, a hook-like crack was observed in an electric resistance (seam) weld; whereas hard spots were observed near the bond line of a double-submerged arc (seam) weld. For a given hydrogen gas pressure, comparable FCG rates were observed for the different base metal and weld microstructures. Generally, the higher strength microstructures had lower fracture resistance in hydrogen. In particular, lower fracture resistance was measured when local hard spots were observed in the approximate region of the crack plane of the weld. Samples tested in lower H2 pressure (34 bar) exhibited lower FCG rates (in the lower ΔK regime) and greater fracture resistance when compared to the respective high-pressure (210 bar) hydrogen tests. The hydrogen-assisted fatigue and fracture surfaces were qualitatively characterized using SEM to rationalize the influence of microstructure on the dominant fracture mechanisms in gaseous hydrogen environment.
