Hard-Rock κ0 at KiK-Net Sites in Japan
Authors: Haendel Annabel , Pilz Marco , Cotton Fabrice 
Published: August 2023

ABSTRACT
Site-specific seismic hazard studies require the knowledge of the shear-wave velocity VS and the high-frequency site attenuation parameter κ0 at the reference rock level at depth. The latter one (called κ0,ref) is often not available and hard to derive. In this study, we make use of the KiK-net database in Japan that consists of surface and colocated downhole sensors. We select 175 sites where the bottom sensor is deployed at rock or hard-rock conditions resulting in a database with many recordings at VS≥1500  m/s. This allows us to tackle two questions: first, is it possible to derive κ0,ref from surface recordings? Second, does κ0 reach an asymptotic level at high VS that could be used as a κ0,ref in site-specific seismic hazard studies? Our results show that measures of κ0 derived from S and coda waves are equivalent. Thus, it is not possible to obtain κ0,ref from surface recordings using coda waves. On the other hand, S-wave measurements of κ0 from surface rock sites are close to κ0,ref if VS≥760  m/s or if the sedimentary cover is thin. The values of κ0 decrease with increasing VS and reach an asymptotic value. The scatter in the so obtained κ0,ref is high, but it can be reduced by selecting subregions with similar geological conditions. Finally, we observe that borehole and surface κ0 are correlated, and that the variability of κ0,ref is only slightly reduced compared to κ0 at the surface. Although we cannot exclude any influence of source effects, our findings indicate that κ0,ref has to be considered as a deep site parameter.
A Statistical Approach to Estimate Seismic Monitoring Stations’ Biases and Error Levels

ABSTRACT
Magnitudes are common and important measures for the size of seismic events. The International Data Centre (IDC) of the Comprehensive Nuclear-Test Ban Treaty Organization estimates an event magnitude by averaging the magnitudes calculated by individual stations that detected the event, excluding outliers. This approach assumes that all station magnitudes have the same error level and are unbiased, namely, they have no systematic errors. We show that the body-wave and surface-wave magnitudes published in the Reviewed Event Bulletin (REB) of the IDC are inconsistent with these assumptions. We thus consider a model where each station has an unknown bias and error level. Given a large collection of reported event magnitudes by a network of monitoring stations, we propose a novel approach to estimate each individual station’s bias and error level. From a statistical perspective, this is a challenging problem involving a huge number of variables, because in addition to the stations’ biases and error levels, the event magnitudes are also unknown. Our approach is based on analyzing differences between reported magnitude values at pairs of stations, which cancels out the unknown event magnitudes and allows us to derive a simple and computationally efficient algorithm. We use the estimated station biases as station correction terms and the estimated error levels to compute weights for event magnitude estimation. Using a large data set from the REB with millions of reported station magnitudes, we show that our approach yields more consistent station and event magnitudes.

Abstract:
Backgrounds: The primary aim of this study was to investigate the blood contact and needle-stick injury rates of final-year (year-6) medical students receiving their education and training at medical schools in different regions of Turkey and to analyse the relationships between blood contact and needle-stick injury and the personal variables of students and accreditation certifications of medical schools.
Methods: In this retrospective cohort study, self-reporting questionnaires were completed anonymously by consenting final-year medical students. The study population (N = 7900) included all final-year medical students attending the 76 medical schools of Turkey. Of the 76 medical schools, 13 were selected by stratified random sampling, according to their accreditation certification and geographical location, which resulted in 2786 final-year medical students being contacted for participation. The dependent variable was percutaneous contact and the timing of the contact. The independent variables were the personal characteristics, occupational health and safety knowledge, invasive medical procedure skills, and blood-borne disease knowledge of final-year medical students, as well as, the accreditation certification of medical schools. Comparisons between groups were analysed using Cox proportional hazards regression.
Results: 83.8% (n = 2334) of 2786 final-year medical students contacted, consented to participate. Blood contact rates of 75.2% for intact skin contact, 20.0% for mucosal contact, and 35.4% for percutaneous contact were reported; with27.0% of medical students reporting contaminated blood contact. The average percutaneous time-to-contact was 8.95 ± 0.09 months, with the percutaneous contact rate approaching 50% in the 12th month of the hazard analysis. Percutaneous contact was significantly higher in students who received no formal occupational health and safety training (OR: 1.29; 95% CI: 1.11-1.50) and who attended non-accredited medical schools (OR: 1.45; 95% CI: 1.26-1.66). Percutaneous contact increased significantly in medical students with increasing invasive medical procedure applying scores (OR: 1.06; 95% CI: 1.04-1.09).
Conclusion: The final year of medical education and training is a high-risk period for percutaneous contact, with the evidence suggesting that the high risks could be mediated by implementing appropriate occupational health and safety education and training. The accreditation certification of medical schools is a significant independent variable in exposure risk. The low blood-contact reporting rate among medical students is a serious concern that requires the implementation of appropriate interventional measures.

Teaching with Technology: Putting the 'enhanced' into Technology Enhanced Language Learning (and Teaching).
Authors: Shoecraft Kelly 
Published: August 2023

The use of technology in language teaching and learning has been rising in popularity with rapid developments in technology as well as increased need due to the recent coronavirus pandemic. Moreover, the sheer number of technologies available and the choices with how to implement them can be quite daunting for teachers, particularly those who are new to teaching, or have limited experience with technology. Within the field of Technology Enhanced Language Learning (TELL), it is essential to establish the meaning of ‘enhanced’ and understand how digital practices can be effectively implemented to indeed ‘enhance’ pedagogical practices and contribute to student learning.
In this article, specific technologies implemented in a Master of TESOL university course are presented and evaluated using the TPACK framework (Mishra & Koehler, 2006). Padlet, Video recordings, chat forums and shared documents were effectively implemented to ‘enhance’ the learning through the potential increase in motivation, increased opportunities for participation and through applying language skills to higher order thinking tasks. Additional activity ideas for TELL in TESOL contexts are presented along with considerations for classroom teachers. The evaluation and discussion of these technologies highlight the benefits of TELL and the importance of purposefully choosing technologies based on pedagogical goals.
Evaluation of Effects of Waterflooding-Induced Bilayer Fractures on Tight Reservoir Using Pressure-Transient Analysis Method
Authors: Wang Zhipeng , Ning Zhengfu , Zhan Jie , Guo Wenting 
Published: August 2023

Summary
Waterflooding will open natural fractures to form induced fractures, which differ from hydraulic fractures because the hydraulic fracture is filled with proppant but the induced fracture is not. Natural fractures are connected by waterflooding. However, because the waterflooding pressure is limited, induced fractures cannot run through the entire reservoir but instead form multiple parallel induced-fracture bands in the vertical direction. Currently, using conventional finite-conductivity methods to match field data will obtain unreasonable results, especially the half-length, conductivity of fracture, and reservoir permeability, which lead to the water breakthrough, which cannot be found in time. This paper presents the waterflooding-induced bilayer fracture (WIBF) model, considering induced-fracture dynamic closure (IDC), dynamic induced-fracture storage (DIS), and induced-fracture radial flow (IRF) effects. Two innovative flow regimes are interpreted, which are dynamic induced-fracture flow and early radial flow regimes. Five innovation parameters are introduced into the WIBF model to describe the IDC, DIS, and IRF effects. The WIBF model is calculated and solved by the Green equation and Newman product methods. Induced-fracture storage coefficient and half-length closure equations are derived to characterize the unique induced-fracture properties. Analytical and numerical methods verify the model’s accuracy. The WIBF model matches a type field case to prove its practicability. Results show that compared with the conventional finite-conductivity model, the proposed model matches the field case well and the interpreted parameters are consistent with the water injection profile and actual field data. The pressure derivative curve shows an early horizontal line, identified as a pressure response of bilayer-induced fractures. If the flow regime is misidentified as pseudoradial flow, some obtained parameters will be absurd, and permeability will be amplified many times. In conclusion, physical and mathematical models are established to describe induced fracture. Induced-fracture storage coefficient and half-length equations are derived. Model matching and equation calculation methods are mutually validated to improve the accuracy of the obtained parameters. Dynamic induced-fracture half-length is interpreted quantitatively to make the engineer take action before the water breakthrough. The model in this paper also provides some parameters for infilling well patterns or determining well spacing economically.

Abstract
TDP-43 proteinopathies including frontotemporal lobar degeneration (FTLD) and amyotrophic lateral sclerosis (ALS) are neurodegenerative disorders characterized by aggregation and mislocalization of the nucleic-acid binding protein TDP-43 and subsequent neuronal dysfunction. Here, we developed endogenous models of sporadic TDP-43 proteinopathy based on the principle that disease-associated TDP-43 acetylation at lysine 145 (K145) alters TDP-43 conformation, impairs RNA-binding capacity, and induces downstream mis-regulation of target genes. Expression of acetylation-mimic TDP-43K145Q resulted in stress-induced nuclear TDP-43 foci and loss of TDP-43 function in primary mouse and human induced pluripotent stem cell (hiPSC)-derived cortical neurons. Mice harboring the TDP-43K145Q mutation recapitulated key hallmarks of FTLD, including progressive TDP-43 phosphorylation and insolubility, TDP-43 mis-localization, transcriptomic and splicing alterations, and cognitive dysfunction. Our study supports a model in which TDP-43 acetylation drives neuronal dysfunction and cognitive decline through aberrant splicing and transcription of critical genes that regulate synaptic plasticity and stress response signaling. The neurodegenerative cascade initiated by TDP-43 acetylation recapitulates many aspects of human FTLD and provides a new paradigm to further interrogate TDP-43 proteinopathies.
Gravitational Effect on Fundamental Physical Observables
Authors: Kurihara Yoshimasa 
Published: August 2023

Abstract
This report studies possible gravitational effects on measurements of fundamental physical observables such as the fine structure constant and the lepton magnetic moment. Although a static gravitational potential does not contribute to physical observables owing to Einstein's equivalent principle, a dynamic degree with finite momentum transfer can contribute to them. In other words, a laboratory frame fixed on the Earth is not an inertial system; thus, Earth's gravity can contribute to local observables. We investigate experimental results measuring the fine structure constant and electron and muon magnetic moments using the quantum field theoretic method under the Schwarzschild background field.
We prepare classical vierbein and spin-connection fields owing to the Schwarzschild metric in the momentum space of the local Lorentz space and estimate possible gravitational effects at the surface of the Earth as O(10-9), which is consistent with the current discrepancy between measured and calculated values of the muon anomalous magnetic moment. On the other hand, the gravitational effect does not contribute to the fine structure constant measurements.
We propose a possible test of gravitational effects in particle physics using precise measurement of muon properties in the J-PARK.

Accelerating Discovery: A Novel Flow Cytometric Method for Detecting Fibrin(ogen) Amyloid Microclots Using Long COVID as a Model
Authors: Turner Simone , Laubscher Gert J , Khan M Asad , Kell Douglas B , Pretorius Etheresia 
Published: August 2023

Abstract
ABSTRACT
Long COVID has become a significant global health and economic burden, yet there are currently no established methods or diagnostic tools to identify which patients might benefit from specific treatments. One of the major pathophysiological factors contributing to Long COVID is the presence of hypercoagulability; this results in insoluble amyloid microclots that are resistant to fibrinolysis. Our previous research using fluorescence microscopy has demonstrated a significant amyloid microclot load in Long COVID patients. However, this approach lacked the elements of statistical robustness, objectivity, and rapid throughput. In the current study, we have used imaging flow cytometry for the first time to show a significantly increased concentration and size of these microclots. We identified notable variations in size and fluorescence between microclots in Long COVID and those of controls even using a 20x objective. By combining cell imaging and the high-event-rate and full-sample analysis nature of a conventional flow cytometer, imaging flow cytometry can eliminate erroneous results and increase accuracy in gating and analysis beyond what pure quantitative measurements from conventional flow cytometry can provide. Although imaging flow cytometry was used in our study, our results suggest that the signals indicating the presence of microclots should be easily detectable using a conventional flow cytometer. Flow cytometry is a more widely available technique than fluorescence microscopy and has been used in pathology laboratories for decades, rendering it a potentially more suitable and accessible method for detecting microclots in individuals suffering from Long COVID or conditions with similar pathology, such as myalgic encephalomyelitis.

Published: August 2023

Abstract
After the closure of the large tailing pond of copper sulfide mine, ecological restoration must be carried out. The ecological restoration method of directly using tailing as a vegetation matrix to replace guest soil is a new method. The key to this method lies in improving the substrate environment and carry out phytoremediation. A field test was performed to carry out an enhanced phytoremediation technique for multi-metal contaminated copper tailings by Sudan grass (Sorghum sudanense (Piper) Stapf.), ryegrass (Lolium perenne L.), and Bermuda grass (Cynodon dactylon), using conditioner (TH-LZ01) and straw combination into composite amendments as soil amendments, aimed to obtain the maximum of phytoremediation effect. The 5% conditioner and 0.5% straw (C2S2) were recommended as the optimum chemical proportions for amendment materials. We could find that the chlorophyll, catalase activity, plant length and fresh weight in the 5% conditioner and 0.5% straw (C2S2) applied treatments were notably higher when compared with those of other treatments, indicating that composite amendments could alleviate the toxicity of metals to plants. In addition, adding composite amendments can obviously improve the restoration effect of Sudan grass, ryegrass and Bermuda grass on the pH, water content, electrical conductivity and organic matter of copper tailings. Compared with no treatment, the absorption of metal in leaves of plants treated with composite amendments is lower, but that in roots is enhanced, revealing that the stability of metal in roots is enhanced by composite amendments treatment to a great extent. By applying composite amendments, the metal removal effect of ryegrass appeared to be particularly effective, and by the following order: Cd (48.5%) > Zn (45.8%) > Pb (27.7%) > Cu (21.9%), followed by Sudan grass and Bermuda grass.
Classification and identification of emotion of non-foreign music based on TR-Bi-LSTM emotion analysis
Authors: Yu Ping , Fu XueBo 
Published: August 2023

Abstract

Intangible cultural heritage (IntCH) folk music has garnered considerable attention due to its immense potential cultural, artistic, and commercial value. With the advancement of the national economy, artistic forms have undergone unprecedented diversification, leading to a corresponding cultural impact on IntCH folk music. Unfortunately, this has also led to the loss of some of these invaluable musical traditions. In this study, we propose an improved bi-directional LSTM for accurately classifying and recognizing the sentiment of IntCH music. Our hybrid network model, TR-Bi-LSTM, incorporates an attention mechanism in the bidirectional LSTM, allowing us to enhance the sentiment analysis at crucial junctures in the music and further augment the accuracy of the model. Additionally, we employ a Dense-ResNet network to perform preliminary feature extraction of the emotion of non-foreign music, thereby strengthening the overall effectiveness of the model. Experimental results indicate that our proposed approach surpasses existing models in terms of accuracy, F1 score, and AUC evaluation index, thus making a significant contribution to the transmission and development of non-foreign music.

Abstract

Objectives: To analyze the clinical and biological characteristics and to evaluate the risk factors associated to the mortality of patients with COVID-19 in Commune 4 of the District of Bamako.
Methods: The cohort consisted of COVID-19 patients treated from March 2020 to June 2022 at the Bamako Dermatology Hospital and the Pasteur private Polyclinic in Commune 4 in Bamako. The variables studied were sociodemographic, clinical and biological. For the analysis of deaths, explanatory variables were grouped into sociodemographic factors, comorbidities and symptoms. Binomial logistic regression models were used to test the risk factors for mortality.
Results: Among the 1319 patients included, 38.4% were asymptomatic, 46% and 15.5% developed moderate and severe forms respectively. The predominant signs were cough (48.5%), respiratory difficulty (24.6%) and headache (19.7%). There was a male predominance of 58.2%. High blood pressure (19.9%) and diabetes (10%) are the main comorbidities. Men were in the majority (58.2%). High blood pressure (19.9%) and diabetes (10%) are the main comorbidities. D-dimer<500µg/l was found in 53.3% of cases and the mean hemoglobin level was 12.9±1.7g/l. The case fatality rate was 3.71% in our series. In bivariate analysis, age>60 years, High blood pressure, diabetes, clinical severity, D-dimer <500 µg/l were associated with death. By the logistic regression method, age >60 years, increased heart rate, the severity of disease and mainly acute respiratory distress syndrome (polypnea, respiratory difficulty) were the factors associated with death.
Conclusion: These main findings elucidate the factors associated with severity and lethality outside of health care system constraints. Old age, heart rate and the development of respiratory distress were the factors associated with increased fatalities.
Suspension nonlinear analysis and VSS-LMS adaptive filtering control of satellite borne flexible structure
Authors: Ma Guoliang , Chen Liqun 
Published: August 2023

Abstract

Satellite borne flexible structure is a multi-degree-of-freedom system, which contains complex dynamic characteristics such as time-varying parameters, geometric nonlinearity, gap nonlinearity, and so on. Flexible structure suspension typically results in geometric nonlinearity. The oscillation equation with nonlinear term is established according to the law of motion of a nonlinear pendulum and considering the influence of medium swing angle and lateral force. The perturbation approach is used to get the relationship between vibration frequency and the nonlinear term, and the impact of factors on vibration characteristics is investigated. The satellite borne flexible structure's active vibration control(AVC) system is then established. Considering proportional differential(PD) or fuzzy control adjustment, variable step size least mean square(VSS-LMS) adaptive filtering algorithm is used to calculate the control signal, and considering the influence of geometric nonlinearity, the actuator is used to suppress the vibration of the satellite borne flexible structure. Finally, the vibration response's amplitude under steady-state excitation significantly decreases as an outcome of the vibration control simulation.
