Shear Wave Velocity measurement from different approaches and its effects on seismic site classification

Knowledge of the dynamic response of subsurface strata is necessary to model the dynamic behaviour of structures during earthquakes. This necessitates the determination of dynamic properties of the soil and seismic site classification, which needs in-situ and laboratory testing. The main objective of this study is to compare seismic site classification by drilling boreholes with Standard Penetration Test (SPT) N value measurement along with hammer energy recordings at positions below the anvil and above the split spoon sampler, measuring shear wave velocity (Vs) by seismic surface wave method of Multichannel Analysis of Surface Wave (MASW) and seismic borehole method of Crosshole (CH) testing at the same sites in India. SPT N values are corrected considering energy below the anvil and above the sampler, and then the same is used to estimate Vs values and to arrive at the seismic site classifications. Additionally, the Vs profile of the same site is compiled from MASW and CH measurement and used to determine the seismic site classifications. Three types of seismic site classifications are adopted in this study, the first one is 30 m average as per the widely used conventional method; second, average Vs values up to engineering bedrock for shallow bed rock sites; and third, Vs values up to layer having Vs of 1500 m/s. Field experiment and different Vs values measured by the two methods are discussed and compared. Further, the difference in seismic site classification when energy-corrected N values are used, and different ways of Vs measurement are presented.
Numerical modelling of soil nailing combined with flexible facing for slope stabilization

Soil nailing combined with a flexible facing made from steel wire meshes is a commonly used and economically efficient structural system for slope stabilization. The overall stability of an unstable slope will be provide by the flexible slope stabilization system. The paper presents a first numerical study on an over-steepened slope. The numerical system and the basic modelling approaches are described. By using a 3D-numerical model the relevance of the shear strength of the soil on the deformation and load bearing behavior is investigated. The deformation of the whole slope stabilization system increases strongly by decreasing cohesion. Current designing approaches does not predict the deformation and calculates an ultimate limit state of the slope stabilization. In consequence, no analytical approach to verify the serviceability of such a system exists. The numerical studies which were conducted in this publication are a first step in a current research project to verify and improve the analytical calculation approaches.

Self-criticism, Self-Silencing and Depressive Symptoms in Adolescents

The present study aimed at examining the relationship between self-criticism, self-silencing and depressive symptoms among adolescents. It was hypothesized that there is likely to be a positive relationship between self-criticism, self-silencing and depressive symptoms. A sample of 121 adolescent boys (n=61) and girl (n=60) of mean age 17.95 (SD= 1.09) was selected through probability random sampling strategy based on the inclusion criteria recruited from government sector colleges of Lahore. The English version of ‘Depressive Experience Questionnaire (Blatt, D’Affliti & Quinlan, 1995), Silencing the self-scale (Jack & Dill, 1992), and Centre for epidemiological studies depression-Revision (Eaton et. al., 2004) were administered to the participants. Pearson product moment correlation showed a significant positive relationship among self-criticism, self-silencing and depressive symptoms. A hierarchical regression analysis depicts that both self-criticism and self-silencing significantly predict depressive symptoms in adolescents. Moreover, girls are more likely to experience depressive symptoms. The findings of the present study help in identifying the psychological issues and vulnerable population of adolescents who can be referred for psychological intervention.

Classification of minority class in imbalanced data sets

: This paper focuses on imbalanced data sets and uses different methodologies for the part of classification process related to building train and test subsets. Popular classification methods are then applied and evaluated based on the recall result for the minority class. On the basis of the results from our experiments we suggest that for imbalanced data sets when the minority class presents noticeably higher interest, we should use alternative methodology for building the train subset and not the standard random allocation of observations, in order to improve the predictive power of the classifier for the minority class

The Sensitivity of Community Extra-Structural Features on Event Prediction in Dynamic Social Networks

A dynamic Online Social Network is a special type of evolving complex network in which changes occur over time. The structure of a community may change over time due to the relationship changes between its members or with other communities. This is known as a community event. In this paper, we discussed the effect of important individual community features and the lengths of adequate time intervals considered in the analysis of the behavior of social networks on the prediction accuracy of each event. Furthermore, we introduced the extra-structural features as global social network features to justify the relationship between the lengths of time intervals used in the model training by using the best prediction accuracy of events. We found a relationship between the scale of network dynamics and the length of time intervals for observing the spread and decomposed events. Finally, by comparing the accuracy of the model based on time interval length which investigated based on cps-value in this study and using the Event Prediction in Dynamic Social Network (EPDSN) model, the hypothesis of a reverse relationship between cps growth rate and time interval length to obtain better prediction accuracy for both the spread and decomposed events.

Incorporating Transformers and Attention Networks for Stock Movement Prediction

Predicting stock movements is a valuable research field that can help investors earn more profits. As with time-series data, the stock market is time-dependent and the value of historical information may decrease over time. Accurate prediction can be achieved by mining valuable information with words on social platforms and further integrating it with actual stock market conditions. However, many methods still cannot effectively dig deep into hidden information, integrate text and stock prices, and ignore the temporal dependence. Therefore, to solve the above problems, we propose a transformer-based attention network framework that uses historical text and stock prices to capture the temporal dependence of financial data. Among them, the transformer model and attention mechanism are used for feature extraction of financial data, which has fewer applications in the financial field, and effective analysis of key information to achieve an accurate prediction. A large number of experiments have proved the effectiveness of our proposed method. The actual simulation experiment verifies that our model has practical application value.
Multi-responsive micro/nanogels for optical sensing

ABSTRACT Micro/nanogels are unique materials that exhibit the properties of both colloids and hydrogels, i.e. being colloids they exhibit a large specific surface area, while they are hydrophilic and porous allowing them to swell to a great degree with water. Engineering micro/nanogels, through the rational design of various polymer compositions and/or optical structures, can enable them to respond to a myriad of stimuli, e.g. temperature, pH, biomolecules, CO2, light, and electricity. These multi-responsive micro/nanogels and their assemblies, are capable of recognizing and transducing analyte signals into changes in optical properties observable spectroscopically or via the naked eye, allowing their use as optical sensors. In this review, we have highlighted recent state-of-the-art examples of stimuli-responsive micro/nanogel-based systems for optical sensors. Graphical Abstract
Energetically Informed Niche Models of Hydrogenotrophs Detected in Sediments of Serpentinized Fluids of the Samail Ophiolite of Oman

A geochemical gradient established by mixing between reduced, hyperalkaline (pH > 11), H2‐rich fluids generated through the process of serpentinization and surrounding surface water (pH ∼ 8) in the Samail Ophiolite of Oman provides an opportunity to characterize the geochemical and biological factors that influence the distribution of H2 oxidizing chemotrophs, hydrogenotrophs. In this study, 16S rRNA gene amplicon sequencing was implemented to characterize hydrogenotrophs in sediments underlying surface expressed serpentinized fluids in Oman. Hydrogenotroph phylotype distribution was evaluated as functions of chemical energy supplies for their given metabolic redox reactions. Through this approach, it was discovered that hydrogenotrophic taxa are likely constrained to sediments with overlying fluids that have <∼60 μm O2, including microorganisms of the genus, Hydrogenophaga. Sulfate reducers of the family, Thermodesulfovibrionaceae, likely require >∼10 μm SO4−2 for survival. In sediments with fluids having >∼10 μm SO4−2, sulfate reducers likely outcompete microorganisms of the methanogen genus, Methanobacterium, for H2. Additionally, differences in distribution between Thermodesulfovibrionaceae and Methanobacterium may be driven by the availability of electron acceptors and the redox reaction that is most energy yielding in the fluid. Taken together, observations from the Oman geochemical gradient result in a hydrogenotroph niche model that can be used to evaluate global distribution patterns of hydrogenotrophs in continental serpentinized fluids. On a global scale, based on previous studies, Methanobacterium is constrained to fluids that have <∼10 μm SO4−2.
Comprehensive Analysis of Prognostic Value and Immune Infiltration of MMP12 in Esophageal Squamous Cell Carcinoma

Esophageal squamous cell carcinoma (ESCC) is a typical neoplastic disease and a frequent cause of death in China. The prognosis of most ESCC patients is still poor. Previous studies demonstrated that MMP12 is involved in tumor metastasis. However, its clinical significance and association with cancer immunity remained largely unclear. In this study, we first analyzed the expressing pattern of MMPs in ESCC from TCGA datasets and found that several MMPs expression was distinctly increased in ESCC. However, only MMP12 expression was associated with five-year survival of ESCC patients. Then, we focused on MMP12 and found its high expression was positively related to advanced clinical stages of ESCC specimens. KEGG assays revealed MMP12 may influence the activity of several tumor-related pathways, such as the Toll-like receptor signaling pathway, TNF signaling pathway, and IL-17 signaling pathway. Then, we sought to determine whether MMP12 expressions were related to immune cell infiltration in ESCC. We observed that increased MMP12 levels were positively associated with the infiltration levels of mast cells activated and macrophages M0. However, eosinophils, B cells naïve, and mast cells resting exhibited an opposite result. Finally, we showed that knockdown of MMP12 suppressed the proliferation of ESCC cells. Overall, our findings proved that high expression of MMP12 may be a novel and valuable prognostic factor in ESCC.
Current Understanding of the Equatorial E x B Drift velocities in the African Sector: A Short Review

A short review of the pattern and morphology of the equatorial plasma drift velocities, particularly during the evening-time Pre-reversal enhancement (PRE) period in the African region had been presented. The seasonal PRE peak values across some locations in the West-African region were considered and compared with other sectors of the world. While most plasma drift observations in the African region were calculated from ionosonde measurements, the observations from other sectors involved direct measurement from satellite and the Incoherent Scatter Radar (ISR) observations. The importance of the PRE in ionospheric electrodynamics was highlighted, the better in the use of either the virtual or real heights of the F-layer in inferring vertical drift velocities were enumerated, revealing the strengths and weakness of each method. The general observations revealed that PRE peak magnitude is commonly weaker in the African region in comparison with the American/Peruvian and Indian sectors, seasonal and solar activity dependent, and could be higher during either magnetic quiet or disturbed activity than when both magnetic activity conditions are combined. The first work to present a regional PRE model around the African equatorial ionization anomaly region (Adebesin et al model) was mentioned. The relevance of the E × B drift in quantifying the daytime equatorial electrojet (EEJ) current was also discussed.
The Known and Unknown About the Nature and Assessment of L2 Listening

ABSTRACT Although second language (L2) listening assessment has been the subject of much research interest in the past few decades, there remain a multitude of challenges facing the definition and operationalization of the L2 listening construct(s). Notably, the majority of L2 listening assessment studies are based upon the (implicit) assumption that listening is reducible to cognition and metacognition. This approach ignores emotional, neurophysiological, and sociocultural mechanisms underlying L2 listening. In this paper, the role of these mechanisms in L2 listening assessment is discussed and four gaps in understanding are explored: the nature of L2 listening, the interaction between listeners and the stimuli, the role of visuals, and authenticity in L2 listening assessments. Finally, a review of the papers published in the special issue is presented and recommendations for further research on L2 listening assessments are provided.
Total Hip Arthroplasty When Utilised in Young Adults Is a Cost-Effective Procedure: A 10-Year and Lifetime Cost-Utility Analysis

Purpose The primary aim of this study was to determine the cost-effectiveness of total hip arthroplasty (THA) in patients aged 25 years and under by calculating the cost per quality-adjusted life year (QALY) gained at 10 years post-operatively, and over the course of a lifetime. Secondary aims were to describe the change in health-related quality of life (HRQoL), Oxford hip score (OHS), and satisfaction in these patients. Methods From 2000 to 2016, 33 patients undergoing THA aged 25 and under had pre-operative and one-year post-operative EuroQol five-dimensions (EQ-5D) scores and OHS recorded prospectively. Post-operative change in EQ-5D allowed calculation of a health-utility score, which, when combined with life expectancy, gave total QALYs gained. Results The mean age was 20 years (range 13.3-24.9), with 23 females (72.7%). Mean number of QALYs gained was 21.1 (95% CI 14.1-28.2). Total lifetime cost per patient was £14641, giving a mean cost per QALY of £4183 at 10 years post-operatively, and £694 over the total remaining lifetime. Discounting total QALYs gained at a rate of 3.5% and 5% per remaining year of life expectancy increased the mean cost per QALY to £1652 and £2187, respectively. Mean pre- and post-operative EQ-5D index were 0.27 (SD 0.27) and 0.63 (SD 0.29), respectively (p=0.0001). Mean pre-operative and post-operative OHS was 37.5 (SD 7.9) and 19.7 (SD 6.94), respectively (p<0.00001). Conclusion THA remains a cost-effective intervention for patients aged 25 years and under. It is also associated with significant improvement in HRQoL, OHS, and high levels of patient satisfaction in this unique patient group.

Influence of weathering on mechanical properties of culm samples of Guadua angustifolia Kunth bamboo with and without nodes

ABSTRACT Bamboo is a lignocellulosic material traditionally and increasingly appreciated as a structural material in construction within the context of a low-carbon circular bioeconomy. Evaluating changes in its basic mechanical properties when exposed to outdoor climatic conditions is of key importance. This paper describes bamboós behavior under compressive stresses in the direction of the culm, tensile and bending, when exposed to natural environmental conditions for two years, in comparison with control samples under stable conditions in a climatic chamber during the same period. Specifically, culms of the Guadua angustifolia Kunth species were exposed to the climatic conditions of the city of Granada (southern Spain). The results attest to a decrease of up to 9% in compressive strength, yet no influence in tensile or bending strength when the silica layer is placed on the compression face. Furthermore, the node enhances stiffness near the points of load application at bending, the node area undergoing lower stress, while the maximum stress and modulus of elasticity in a tensile state are reduced. The influence of nodes in compression is not relevant.
