Abstract
High seismicity rates in and around West Java occur as a result of the Indo-Australian plate converging with and subducting beneath the Sunda plate. Large megathrust events associated with this process likely pose a major earthquake and tsunami hazard to the surrounding community, but further effort is required to help understand both the likelihood and frequency of such events. With this in mind, we exploit catalog and phase data sourced from the Agency for Meteorology, Climatology, and Geophysics (BMKG) of Indonesia and the International Seismological Centre (ISC) for the period of April 2009 through July 2020, in order to conduct earthquake hypocenter relocation using a teleseismic double-difference method. Our results reveal a seismic gap to the south of West Java, which is in agreement with a previous GPS study that finds the same region to be a potential future source of megathrust earthquakes. Tsunami modeling was conducted in the region based on two scenarios using sources from the Indonesian National Center for Earthquake Studies, and show that the maximum tsunami height may be up to ~ 8 m. This estimate is approximately half the maximum tsunami height predicted by a previous study in which earthquake sources were derived from GPS data inversion.

Abstract
Background

Maintaining oral health is one of the global public health challenges. Income and out-of-pocket payments for dental care services are predictors of dental care utilisation. Although public assistance programmes guarantee income security for impoverished people, access barriers other than financial costs may cause unmet needs of dental care. We aimed to explore the potential sociodemographic factors determining dental care utilisation among recipients of public assistance in Japan using linkage data of public assistance database and medical assistance claim data administered by municipalities.
Methods

This was a retrospective cohort study involving a sample of public assistance recipients. We extracted the recipients’ sociodemographic data (age, sex, household number, employment status, nationality, disability certificates, and long-term care status) in January 2016 and observed them until December 2016 to identify incidences of dental care utilisation as outcomes. We performed a multivariable Poisson regression analysis, with a robust standard error estimator to calculate the incidence ratio (IR) of dental care utilisation in each variable.
Results

We identified a total of 4,497 recipients at risk. Among them, 839 recipients used dental care services. The female recipients had a higher incidence of dental care utilisation when compared to the male ones (adjusted IR, 1.22; 95% confidence interval [CI], 1.08–1.38). Immigrant recipients had a higher incidence of dental care utilisation than the Japanese ones (IR, 1.53; 95% CI, 1.16–2.01). Recipients with psychological disabilities had higher incidences than those without disability certificates (IR, 1.30; 95% CI, 1.08–1.56).
Conclusions

Non-financial sociodemographic inequities in dental care utilisation stemming from sex, nationality, presence of psychological disability were found despite minimum income protection and equitable financial dental service access amongst public assistance recipients in Japan. Providing targeted preventive care and treatments for dental care among underserved populations is required to tackle oral health inequities.

Abstract
Background: A perfect stroke is essential for winning table tennis competition. A perfect stroke is closely related to reasonable stroke structure, which directly affects the stroke effect. The main purpose of this study was to examine the correlations between the structural characteristics of stroke and the stroke effect. Methods: Forty-two young table tennis players were randomly selected from China Table Tennis College (M age = 14.21 ± 2.13; M height = 1.57 ± 0.14 m; M weight = 46.05 ± 6.52 kg, right-hand racket, shake-hands grip, no injuries in each joint of the body). The high-speed infrared motion capture system was used to collect the data of stroke structural characteristics, and the high-speed camera was used to measure the spin speed of the stroke. The influence of striking structural characteristics on striking effect was examined.Results: The time duration of backswing and forward motion were significantly correlated with ball speed (r = -0.403, p < 0.01; r = -0.390, p < 0.01, respectively) and spin speed (r = -0.244, p = 0.027; r = -0.369, p < 0.01, respectively). The linear velocity of right wrist joint was positively correlated with ball speed (r = 0.298, p < 0.01) and spin speed (r = 0.238, p = 0.031). The angular velocity of right elbow joint and right hip joint were positively correlated with ball speed (r = 0.219, p = 0.013; r = 0.427, p < 0.01, respectively) and spin speed (r = 0.172, p = 0.048; r = 0.277, p = 0.012, respectively). The angular velocity of right knee joint had a significantly negative correlation with placement (r = -0.246, p = 0.026). The angular velocity of right ankle joint had a significantly positive correlation with the ball speed (r = 0.443, p < 0.01).Conclusions: The time allocation of the three phases of backspin forehand stroke had an important impact on stroke effect, especially the ball speed and spin speed. The ball speed of the stroke was mainly affected by the translation of the right wrist joint. The spin speed of the stroke was mainly affected by the translation of the right wrist joint. The placement of the stroke was mainly affected by the rotation of the right knee joint.

Abstract
Introduction: This study aims to assess the effectiveness of flipped learning in trauma rotation of first-year general surgery residents. This method entails the use of books, podcasts, and movies prior to the discussion of the topics in the classroom/conferences.Method: All (n=15) junior general surgery residents in Shiraz medical school. In the quantitative phase of the study, 3 test scores were compared. All tests were composed of 20 multiple choice clinical scenarios. A pretest was done on the registration date. After that, the media (videos and podcasts) and books were given to the residents. One month later, the residents had a case-based discussion on the primary trauma survey. An early post-test was done immediately after the case-based discussion, and a late post-test one month following commencement of the program. Also, a semi-structured phone interview was done with residents by an external audit. Results: The was a significant correlation between pretest (Mean=10.733,SD=2.25) and early post-test scores (Mean=12.8 ,SD=1.82) among residents (P=0.004) . Moreover, residents had a higher delayed post-test score (M=13.267, SD=1.53) in comparison to the pre-test (P=0.002). Surprisingly there was no significant difference between early and late post-test (P=0.404). The resident was also satisfied with the overall usefulness of the program for junior residents (overall score 4/5). We did not find any correlation between gender with the test scores. In the qualitative phase of the study, we noticed that our participants tend to use podcasts more than other materials. They believed that the videos and books help more to foster theoretical knowledge. The case-based discussion makes them more confident in dealing with the patients in their daily encountersConclusion: Finding in this study reveals that flipped learning can be a useful, highly beneficial platform and promotive for junior general surgery programs.

Abstract
BackgroundThe rapid development of active remote sensing laser scanning technology has led to the accumulation of substantial data on long-term forest changes. Accurate selection of the key parameters from larger amounts of cloud data is a prerequisite for volume estimates of standing trees. This study collected three phases of data over 5 years from Liriodendron chinense plantation forest. A series of the height-related characteristic parameters was extracted from the scanned points of each tree stem, which includes a novel feature of the height cumulative percentage (Hz%) proposed by us. Meanwhile, taking the manually measurements directly from the terrestrial laser scanning (TLS) data as the ground truth, the performance of various models combined with the characteristic parameters on the prediction of the wood volume of each tree was evaluated for the purpose of determination of the optimal parameters and prediction models suitable for the tree species of Liriodendron chinense. Results﻿The shape of the upper tree trunk extracted by the point cloud is equivalent to that of the analytical tree with inflection points at 25% and 50% of the height. Among the correlations between the hierarchical features and volumes, the parameters with the highest correlations are H25 and H50. The hierarchical parameters were selected for volume modeling. H25 and diameter at breast height (DBH) were used for all three phases, for which the fitted R2 reached 0.951, 0.957 and 0.901. The modeled dynamic volume change was highly correlated with the actual point cloud-extracted volume change. In the linear relation, the intercept is -0.081, and the slope is 1.14. ConclusionsThe Hz% value provided by multi-station scanning was closely related to the characteristic stumpage parameters and could be used to invert the dynamic forest structure. The volume model based on point cloud hierarchical parameters could be used to monitor the dynamic changes in forest volume and provide an updated reference for applying TLS point clouds for the dynamic monitoring of forest growth information.

Published: November 2020

Abstract
Background: The vernalization, in which the plants must undergo a prolonged winter cold exposure to flower, is mainly controlled by a suppressive MADS-box gene FLC in Arabidopsis. However, different from Arabidopsis, the CCT-domain containing gene VRN2 is the critical vernalization-related suppressor gene in cereals. Based on this apparent diversity of vernalization in different plants, and involvement of VRN2 with vernalization in cereals, we conducted a genome-wide analysis of CCT genes in wheat, and the relationship between vernalization and these genes were also revealed.Results: A genome-wide analysis of the CCT genes in common wheat was performed by employing a hidden Markov model-based method, and 127 sequences, which assigned to 40 clusters, were obtained in three subgenomes. Specially, two of the gene clusters are duplicated, and distinguishingly located near telomere. Furthermore, these sequences were classified into eight groups by a phylogenetic analysis procedure using the UPGMA method, and this taxonomy is concordant to the classification based on CCT interruptions and domain organization which roughly divided the proteins into four divergently related subfamilies. Moreover, the expression of several CCT genes is continually downregulated during and after vernalization, but no continually upregulated CCT genes were revealed, as indicated by transcriptome sequencing and real-time quantitative PCR analysis.Conclusion: This study improves our understanding of the structure and function of CCT genes, suggests many vernalization-related CCT genes, and may guide future investigations on CCT genes and vernalization in wheat.

Abstract
Objective: To analyze relevant risk factors for severe postpartum hemorrhage in patients with placenta accreta spectrum to improve the ability to identify patients with high-risk for intraoperative bleeding and improve maternal outcomes. Methods: This study is a retrospective study. Placenta accreta patients who delivered by cesarean section at Peking University Third Hospital from September 2017 to December 2019 were selected and included, according to the amount of intraoperative bleeding, in the severe bleeding group (bleeding volume ≥ 2000 mL, 68 cases) and nonsevere bleeding group (bleeding volume <2000 mL, 99 cases). Univariate analysis and multivariate logistic regression were used to analyze the correlations between related risk factors or ultrasound imaging characteristics and the severity of bleeding during operation. Results: (1) There were statistically significant differences in gravity, parity, number of prior cesarean deliveries and placenta accreta ultrasound scores (p <0.05) between the two groups of patients. (2) Among the ultrasonographic indicators, the disappearance of the postplacental clear space, the emergence of cross-border blood vessels in the region of subplacental vascularity, interruption or disappearance of the bladder line, and the presence of the cervical blood sinus had the most significant correlation with hemorrhage during placenta accreta (p <0.05).

Published: November 2020

Abstract
Background & objective: Hypertensive disorders of pregnancy including preeclampsia can be associated with preterm birth and infant mortality and morbidity. It seems that intraventricular hemorrhage (IVH) in preterm neonates born to hypertensive mothers is less common compared to the other ones. In this study, we assessed the relationship between hypertensive disorders of pregnant mothers and the incidence of intraventricular hemorrhage in preterm neonates weighing less than 1500 grams. Methods: In this case-control study, 305 singleton preterm neonates with a birth weight less than 1500 g were entered. The presence of IVH in all preterm neonates was assessed using brain ultrasonography and its correlation to hypertensive disorders of their mothers were evaluated.Results: The prevalence of preeclampsia in mothers with and without prepregnancy hypertension was 40%, and 15.09% respectively. The prevalence of IVH in preterm neonates was 26.9% (n=82). The incidence of IVH in preterm neonates of mothers with and without preeclampsia was 16.07%, and 29.31% in (p=0.028), respectively. The prevalence of IVH in preterm neonates of mothers with hypertension and without hypertension was 12.5% and 29.05%, respectively (p=0.018). Preterm neonates with IVH had a lower mean birth weight, smaller gestational age and lower Apgar scores compared to preterm neonates without IVH with p values of <0.001, <0.001 and <0.01, respectively.Conclusion: Hypertensive disorders of pregnancy increases the risk of preterm delivery, but incidence of IVH in preterm neonates weighing less than 1500 gr is lower in infants born to mothers with hypertension including preeclampsia compared to non hypertensive mothers. And also lower gestational age, birth weight, and Apgar scores were important predicting factors for IVH in preterm neonates.

Published: November 2020

Abstract
IntroductionEffusive constrictive pericarditis (ECP) is a unique clinical syndrome that is characterized by the coexistence of pericardial effusion and constrictive pericardium. The etiology of ECP usually contains tuberculosis, idiopathic, and neoplastic causes. The early diagnosis, treatment strategy and prognostic predictor of ECP still remain a big problem nowadays due to the sophisticated clinical situations. Case PresentationWe here report a rare case of idiopathic ECP with thickened adherent visceral pericardium and normal parietal pericardium, accompanying multiple complications mainly comprising severe tricuspid regurgitation, hypoproteinemia, and proximal deep venous thrombosis. The patient was referred for radical pericardiectomy successfully, but the long-term prognosis may be unfavorable. DiscussionThis case aims to provide some clinical experience of such situation in which the clinician should weight the benefits and the risks to a particular patient.

Published: November 2020

Abstract
Background: Independent and open brain-computer interfaces (BCIs) working outside the laboratory environment are still rare. Their most limiting factors include low classification accuracy, information transfer bit-rate, low variability of used approaches, and closeness of the hardware and software components of the system. The presented BASIL project has focused on the design, development and testing of an open and affordable BCI system that is built on low-cost hardware and open-source software components. It provides people with motor impairments with an opportunity to control their basic home environment.Methods: The concept of the BASIL prototype follows the best practices that are known within the construction of BCI systems, adds the concept of the cloud for remote BCI computations, relies on testing and customization of the whole system to the needs of individuals, and focuses on the open solution affordable for ordinary users. The core components of the BASIL project solution include hardware components for signal acquisition and software components for local execution of online BCIs.Results: The BASIL system was tested on ten participants in laboratory conditions. We failed to evoke a reliable P300 component with eight-trial averages. Eyes blinks, alpha activity, and steady-state visually evoked potentials were clearly observable. Dry electrodes with long pins were preferred by most users. Out of ten participants, six were able to control the system online, achieving more than 70 % accuracy.Conclusions: The results show that a successful BCI system can be built on low-cost hardware for EEG signal acquisition and amplification. The current solution, the prototype of the open and affordable BASIL BCI system, is prepared for further community development and testing.

Abstract
Background: Hesperetin, an active compound found in citrus fruits, possesses antiproliferative effects toward several types of cancer cell lines, including cervical cancer. In this study, we explore the antitumor effects of Hesperetin on the human cervical cancer human papilloma virus (HPV)-positive (CaSki and HeLa) and HPV-negative (C-33A) cell lines and further elucidated the underlying mechanisms of this action. Methods: Cell viability and proliferation was measured by the MTT assay and 5-ethynyl-2′-deoxyuridine (EdU) incorporation assay, respectively. dUTP-fluorescein nick end-labeling (TUNEL) staining, Annexin V‑fluorescein isothiocyanate (FITC)/propidium iodide (PI) staining and flow cytometry was used to assess the degree of apoptosis. JC-1 staining assay was used to evaluate the change of mitochondrial membrane potential (ΔΨm) and Western blot assays were used to determine apoptosis-related factors at protein level. Results: Hesperetin (100, 200 and 400 μM) exhibited a significant exclusive inhibitory effect against the growth of HPV-infected CaSki and HeLa cancer cells via induction of apoptosis in a concentration-dependent manner, while it was almost not active in HPV-negative C-33A cancer cells and normal cervix epithelial H8 cells. Moreover, this antitumor effect executed by Hesperetin was associated with disruption of ΔΨm, the release of cytochrome c from mitochondria, activation of pro-apoptotic proteins (Bax, cleaved caspase-3 and caspase-9) and inhibition of anti-apoptotic proteins (Bcl-2). During this process, cleaved caspase-8 remained unchanged. In addition, Hesperetin led to a downregulation of E6 oncoprotein expression and upregulation of tumor suppressor protein p53 level. Conclusions: Collectively, these results implicated that Hesperetin can induce apoptosis of HPV‑positive cervical cancer cells via a mitochondria-mediated intrinsic signaling pathway, together with the repression of E6 and enhancement of p53 protein level, indicating Hesperetin may be considered as a potential candidate for the development of innovative anti-HPV cervical cancer agents.
