The Risk of Liquefaction Associated with Water Head Fluctuation in the Low-lying Area of Tokyo

 In the wide area of the eastern part of Tokyo, the ground level is less than mean sea level. This area is more vulnerable to disasters than other areas. If large flood damage such as storm surge should occur in this area, the disaster would be a long-term catastrophe. On the coast of Tokyo Bay, countermeasures have been taken by tide embankments and floodgates. However, considering the damage scale when it occurs, an analysis in this area is very important. In this area, ground settlement occurred and groundwater head dropped because groundwater excessively withdrew by the industrial purpose during the period of economic growth. Currently, the groundwater head recovers and the ground settlement has been subsided. However, due to the groundwater head fluctuation, pore water pressure distribution had been different from hydrostatic pressure distribution. Therefore, in the analysis in this area, it is necessary to consider past groundwater head fluctuation. In this research, the ground settlement and the distribution of pore water pressure are simulated from groundwater level fluctuation over the past 100 years. Then, we conducted the seismic analysis by input the distribution of effective stress calculating from the simulated ground water pressure. The sites analyzed in this research are Tokyo Sea Life Park at the mouth of Arakawa River

Application of Partitioned Iterative Coupling Approach to Multi-physics

 The engineering needs which have to consider the multi-physics are increasing. When the multi-phase problem is treated by monolithic coupling approach, there are some difficulties such as the increase in the number of degree of freedom, the complication of the program code and so on. In order to overcome these shortcomings in considering the new additional phase, we applied the partitioned iterative coupling approach to the Hydro-Mechanical coupled problem in this research. In the partitioned iterative coupling approach, the behavior of single phases can be individually calculated and the interaction between the phases has been considered at an appropriate timing by the middleware. The middleware plays a role to regulate the single-phase analysis. In this research, we carried out the numerical simulation of one-dimensional consolidation by both the partitioned iterative coupling scheme and the monolithic coupling scheme, and then we confirmed that the numerical results are the same. Through the research, it figured out the efficient iterative scheme

C-arm Cone-beam CT-guided Needle Biopsies through the Erector Spinal Muscle for Posterior Thoracic Pulmonary Lesions

This study investigated retrospectively the diagnostic yield and complication rate of transthoracic needle biopsies for posterior thoracic pulmonary lesions using C-arm cone-beam computed tomography （CBCT）. The risk factors for pulmonary hemorrhage were evaluated. Our study included 113 patients with 113 posterior pulmonary lesions （mean longest diameter: 30.6mm, and mean depth: 4.7mm） through the erector spinal muscles using a 19/20-gauge coaxial system. The diagnostic performances of procedures for malignant lesions and the incidence of complications after biopsies were also assessed. The patient-related and procedure-related variables were investigated. Risk factors for pulmonary hemorrhage were analyzed with a multivariate logistic regression analysis. Findings revealed 99 malignant, 13 benign, and one intermediate lesion. Sensitivity, specificity, and diagnostic accuracy rates were 100％ （99/99）, 92.3％ （12/13）, and 99.1％ （111/112）, respectively. Air embolization, hemothorax, hemoptysis, pneumothorax, and pulmonary hemorrhage, occurred in 0, 2, 12, 48, and 70 procedures. The averaged spinous process-pleura depth and the traversed lung parenchyma depth achieved by the introducer needles were 54.2mm and 27.4mm, respectively. The needle position at the pleural puncture site within the intercostal space was in middle （31％） and inferior （69％） areas. The incidence of pulmonary hemorrhage was significantly higher in smaller lesions （p＝0.001）. Manual evacuation was performed in five procedures for patients with pneumothorax. The chest tube placement （trocar＞8 Fr） was performed in two procedures in patients with hemothorax and pneumothorax. In conclusion, the biopsy method with a posterior intercostal approach for posterior thoracic pulmonary lesions yielded high diagnostic accuracy and few major complications

Annual (2023) taxonomic update of RNA-directed RNA polymerase-encoding negative-sense RNA viruses (realm Riboviria: kingdom Orthornavirae: phylum Negarnaviricota)

55 Pág.In April 2023, following the annual International Committee on Taxonomy of Viruses (ICTV) ratification vote on newly proposed taxa, the phylum Negarnaviricota was amended and emended. The phylum was expanded by one new family, 14 new genera, and 140 new species. Two genera and 538 species were renamed. One species was moved, and four were abolished. This article presents the updated taxonomy of Negarnaviricota as now accepted by the ICTV.This work was supported in part through the Laulima Government Solutions, LLC, prime contract with the U.S. National Institute of Allergy and Infec tious Diseases (NIAID) under Contract No. HHSN272201800013C.
