Microbial diversity and the abundance of keystone species drive the response of soil multifunctionality to organic substitution and biochar amendment in a tea plantation

High nitrogen (N) fertilizer inputs accelerate soil acidification and degradation in tea plantations, thus posing a threat to soil microbial diversity, species composition, and ecosystem service functions. The effects of organic fertilizer and biochar applications on improving soil fertility have been extensively studied on cropland; however, little is known about their effectiveness in promoting soil multifunctionality on rapidly expanding acidic soils in tea plantations. In this study, we conducted a two‐year field experiment in a subtropical tea plantation to investigate the effects of organic fertilizer substitution and biochar amendment on soil microbial communities and multifunctionality. The results showed that soil multifunctionality was enhanced in plots amended with organic fertilizer and biochar. Soil multifunctionality was significantly and positively correlated with alpha‐diversity of bacteria but not fungi. We also found that organic fertilizer substitution and biochar amendment improved soil multifunctionality by altering the abundance of keystone species. The abundance of keystone species classified as module hubs in the bacterial co‐occurrence network contributed significantly and positively to soil multifunctionality. In contrast, the keystone species categorized as module hubs in the fungal co‐occurrence network negatively affected soil multifunctionality. Soil pH was a key driver of soil microbial community composition, indicating that the increase in soil pH under organic fertilizer and biochar amendment had a crucial role in biological processes. These results suggest that organic substitution and biochar amendment are beneficial in preventing soil degradation and maintaining soil multifunctionality in subtropical tea plantations.
Geology of the 2022 Winter Olympic sites, Beijing-Zhangjiakou, China: An analogue of the North China Craton

ABSTRACT The 2022 Winter Olympics will be held in the Beijing-Zhangjiakou area, which is located in the eastern North China Craton (NCC) and contains a comprehensive geological record from the Archaean to Cenozoic. In this paper, we first review the geology of the Beijing-Zhangjiakou area, then, combined with data from the rest of the NCC, we discuss the geological evolution of the area in the context of the NCC. The geological and tectonic evolution of the Beijing-Zhangjiakou area can be regarded as a proxy or analogue for the geological history of the whole of the NCC. Six stages have been divided as follows: 1) Neoarchean massive continental crust growth; 2) Paleoproterozoic cratonization; 3) Meso-Neoproterozoic multi-stage rifting; 4) Palaeozoic marginal orogeny; 5) Mesozoic craton destruction; and 6) Cenozoic intra-plate extension. We hope this paper will be helpful to both geologists and non-geologists who will attend the 2022 Beijing-Zhangjiakou Winter Olympics and may be interested in rocks and geology around the Winter Olympic sites.

Research on Diagnosis Method of Mechanical Fault Based on Support Vector Machines

The Shortage of fault samples is one of the main reasons that restrict the development of intelligent fault diagnosis.Support vector machine(SVM) is a statistic learning method based on less samples proposed in the last decade.In this paper,the classification algorithm of support vector machine is used to deal with the multi-class fault classification problem in intelligent fault diagnosis.The experimental results of trundle bearing fault diagnoses by using SVM is compared with that by using RBF neural network,which shows that the SVM method has higher classification performance than RBF neural network under the condition of restricted samples.
EVALUATION OF POMEGRANATE PEEL AND ITS BEVERAGES AS ANTIBACTERIAL AND ANTICANCER AGENT

Pomegranate (Punica granatum) peel is an important source of bioactive compounds against a varied number of maladies. The main target of the present investigation was to determine the chemical composition, total phenols, flavonoids, and antioxidant activity of pomegranate peel (PGP) as well as the potential biological activities of aqueous peel extract. Antibacterial activity was measured using 20% and 40% aqueous extracts of pomegranate peel (PGPa) using well diffusion plate method against Helicobacter pylori and Campylobacter jujini which are the most common bacteria causing gastric infections worldwide. Pomegranate peel showed high content of total phenols (198.33 mg Gallic acid/g) and flavonoids, (46.86 mg Quercetin/g) with strong antioxidant activity (95.96%). Inhibition percentages of 40% aqueous extracts were 79 and 45.6 % for Campylobacter jujini and Helicobacter pylori at 100 μl/well, respectively. Thus, minimum inhibitory concentration (MIC) of aqueous extract was 125 and 250 μg/ml for Campylobacter jujini and Helicobacter pylori, respectively. Morphological studies by scanning electron microscopy using 20 % of aqueous pomegranate peel (PGPa) showed segmentation, elongation and enlargement of Campylobacter jujini bacterial cells. Antitumor activity of pomegranate peel against intestinal cancer cell lines (Caco-2 cells) was shown at various concentrations of extracts with IC50 120 ±1.30 μg/ml. Sensory evaluation of pomegranate peel beverage at series concentrations from 0.5 to 2.5 % was done to evaluate the impact of its application in the beverage production. This study suggests the possibility that PGP beverage can be used for dietary therapy to treat microbial infections.
The tip-of-the-Mandarin tongue: phonological and orthographic priming of TOT resolution in Mandarin speakers

ABSTRACT Studies of tip-of-the-tongue (TOT) experiences in English have shown that priming the TOT’s first syllable, especially a low-frequency one, helps to resolve the TOT. We explored whether priming of TOT resolution occurs in Mandarin, a language whose visual representation (orthography) is largely independent of sound (phonology). Participants saw descriptions corresponding to cheng-yu targets, four-character Chinese idioms. After a TOT, they saw a list of words where one was sometimes a phonological (Experiment 1) or orthographic (Experiment 2) prime. Phonological primes had a first character different from the target’s but contained either its first syllable or first phoneme, whereas orthographic primes contained the target’s first radical. Results showed that two factors marginally increased TOT resolution: first syllable primes and higher-frequency first radicals. These results are discussed in terms of a transmission deficit model of TOTs in Mandarin where priming of TOT resolution has both similarities and differences with alphabetic languages.
Performances of six reanalysis profile products in the atmospheric correction of passive microwave data for estimating land surface temperature under cloudy-sky conditions

ABSTRACT Passive microwave (PMW) observations from the Advanced Microwave Scanning Radiometer 2 provide a way to obtain cloudy land surface temperatures (LSTs). However, atmospheric corrections must be performed on cloudy LSTs due to the cloud effect at higher frequencies. In this paper, six reanalyzed profiles, including the fifth-generation European Centre for Medium-range Weather Forecasts Reanalysis (ERA5), Interim Reanalysis (ERA-Interim), Japanese 55-year Reanalysis Data (JRA-55), Modern-Era Retrospective analysis for Research and Application V2 (MERRA2), National Centers for Environmental Prediction (NCEP) /Final Operational Global Analysis (FNL), and NCEP/Global Forecasting System (GFS), were compared with 2829 radiosonde profiles derived from the University of Wyoming. Then, their performances in correcting the atmospheric effects of LSTs at cloudy skies were investigated. Results showed that the ERA5 had the best accuracy in revealing the actual atmospheric conditions, and the RMSEs of transmittance, downward radiance, and upward radiance were about 0.007, 2.01, and 1.89 K, respectively. The RMSEs between the estimated LSTs and referenced LSTs varied from 3.15 K of the ERA5 to 6.12 K of the NCEP/FNL, indicating the ERA5 can be recommended for the atmospheric correction of PMW-based LST retrievals. Additionally, transmittance accuracy plays an essential role in impacting the LST retrievals in any weather.

This paper describes the application of a discrete event controller to the simulation of human pilot behavior. The model is calibrated to data collected at a trial conducted at a Boeing 747-400 simulator based at NASA Ames. It is demonstrated that a plausible model of pilot control behavior is constructed and the values of model parameters are similar to those calibrated for a model of human response to a laboratory tracking task.
Effect of Physical Exercise Program on Psychotic Symptoms and Social Functioning of Patients with Schizophrenia

Schizophrenia stands as one of the top 10 leading causes of disability in the world and it is often associated with hospitalization, inadequate treatment and relapse. Physical exercise program is an innovative treatment which may have positive effects on patients with schizophrenia offering a possible adjunctive intervention which may improve both psychotic symptoms and social functioning. Objective: Determine the effect of applying physical exercise program on psychotic symptoms and social functioning of patients with schizophrenia. Setting: The psychiatric inpatient wards of ELMaamoura Hospital for Psychiatric Medicine. Subjects: Seventy (70) randomly selected male patients with schizophrenia were included in this study. Tools: Three tools were used; socio-demographic and clinical data tool, the Brief Psychiatric Rating Scale (BPRSversion 4.0) and the Social Functioning Scale (SFS). In addition, physical exercise program intervention was designed and implemented. Results: The findings revealed that overall psychotic symptoms were significantly improved immediately and after three months of applying the physical exercise program. Also, the results showed significant improvement in social functioning subscales (withdrawal& social engagement, interpersonal communication, independence-competence, recreation and pro social subscale) among the studied patients. Conclusion: Physical exercises have a positive effect on psychotic symptoms and specific social functioning areas. Recommendations: Physical exercise training program should be considered as an integral part in the hospital routine of patients with schizophrenia.
Improving Subsurface Characterisation with ‘Big Data’ Mining and Machine Learning

Large databases of legacy hydrocarbon reservoir and well data provide an opportunity to use modern data mining techniques to improve our understanding of the subsurface in the presence of uncertainty and improve predictability of reservoir properties. A data mining approach provides a way to screen dependencies in reservoir and fluid data and enable subsurface specialists to estimate absent properties in partial or incomplete datasets. This allows for uncertainty to be managed and reduced. An improvement in reservoir characterisation using machine learning results from the capacity of machine learning methods to detect and model hidden dependencies in large multivariate datasets with noisy and missing data. This study presents a workflow applied to a large basin-scale reservoir characterization database. The study aims to understand the dependencies between reservoir attributes in order to allow for predictions to be made to improve the data coverage. The machine learning workflow comprises the following steps: (i) exploratory data analysis; (ii) detection of outliers and data partitioning into groups showing similar trends using clustering; (iii) identification of dependencies within reservoir data in multivariate feature space with self-organising maps; and (iv) feature selection using supervised learning to identify relevant properties to use for predictions where data are absent. This workflow provides an opportunity to reduce the cost and increase accuracy of hydrocarbon exploration and production in mature basins.
Influence on mechanical performance of partial design parameters of PEC columns fabricated with crimping thin-walled built-up section

To systematically study the mechanics performance of PEC columns fabricated with thin-walled built-up section,the FEM software named ABAQUS was adopted to build the FE model on the basis of the test specimens,the concrete strength,strong or weak axis layout and construction details of crimping were taken into consideration 8test specimens of PEC columns were simulated.Compared with load displacement curve and failure mode between specimens and models,the effective behaviors of various design parameters on the loading-carrying capacity and deformation patterns of PEC column were derived.The result shows that the effect of concrete strength on initial lateral stiffness is significant but loading-carrying capacity varies little;PEC layout markedly affects loading-carrying capacity but not initial lateral stiffness and ductility of specimens;the rational size of crimping should effect the failure mode,loading-carrying capacity and the integrity distinctly.
Binge Drinkers Shouldn’t Set Their Own Alcohol Reduction Goals! Evaluating the Effectiveness of Different Goal-Based Alcohol Reduction Interventions among Young People

ABSTRACT The present research aimed to investigate the relative effectiveness of three types of alcohol reduction intervention. Participants were 354 university students from an Australian university. After completing an initial survey, they were randomly assigned to either (a) follow national guidelines for alcohol consumption, (b) set their own personal alcohol consumption reduction goal, or (c) work with their peers to set a goal. Participants then recorded their alcohol consumption in a drinking diary over a period of four weeks. The results showed that participants in the personal goal condition reported significantly higher alcohol consumption than those in the national guidelines conditions, with participants in the group goal condition reporting mid-level alcohol consumption. This effect was moderated by binge drinking propensity. Personal goal setting was most likely to lead to higher alcohol consumption when participants scored relatively high on measures of binge drinking propensity. These findings highlight the point that different types of alcohol reduction interventions may be effective for different types of people. In particular, people who have a relatively high propensity for binge drinking should be encouraged to follow goals that have been set by authorities (e.g., national guidelines) rather than by themselves.
Intraoperative Glycemic Variability and Mean Glucose are Predictors for Postoperative Delirium After Cardiac Surgery: A Retrospective Cohort Study

Purpose Postoperative delirium (POD) is a common but serious complication after cardiac surgery and is associated with various short- and long-term outcomes. In this study, we investigated the effects of intraoperative glycemic variability (GV) and other glycemic variables on POD after cardiac surgery. Patients and Methods A retrospective single-center cohort analysis was conducted using data from electronic medical record from 2018 to 2020. A total of 705 patients undergoing coronary artery bypass graft surgery and/or valve surgery, and/or aortic replacement surgery were included in the analysis. Intraoperative GV was assessed with a coefficient of variation (CV), which was defined as the standard deviation of five intraoperative blood glucose measurements divided by the mean. POD assessment was performed three times a day in the ICU and twice a day in the ward until discharge by trained medical staff. POD was diagnosed if any of the Confusion Assessment Method for the Intensive Care Unit was positive in the ICU, and the Confusion Assessment Method was positive in the ward. Multivariable logistic regression was used to identify associations between intraoperative GV and POD. Results POD occurred in 306 (43.4%) patients. When intraoperative glycemic CV was compared as a continuous variable, the delirium group had higher intraoperative glycemic CV than the non-delirium group (22.59 [17.09, 29.68] vs 18.19 [13.00, 23.35], p < 0.001), and when intraoperative glycemic CV was classified as quartiles, the incidence of POD increased as intraoperative glycemic CV quartiles increased (first quartile 29.89%; second quartile 36.67%; third quartile 44.63%; and fourth quartile 62.64%, p < 0.001). In the multivariable logistic regression model, patients in the third quartile of intraoperative glycemic CV were 1.833 times (OR 1.833, 95% CI: 1.132–2.967, p = 0.014), and patients in the fourth quartile of intraoperative glycemic CV were 3.645 times (OR 3.645, 95% CI: 2.235–5.944, p < 0.001) more likely to develop POD than those in the first quartile of intraoperative glycemic CV. Conclusion Intraoperative blood glucose fluctuation, manifested by intraoperative GV, is associated with POD after cardiac surgery. Patients with a higher intraoperative GV have an increased risk of POD.
Piecewise Attack Strategy Design for T–S Fuzzy Cyber–Physical Systems

This article is concerned with the problem of the stealth attack strategy design for T–S fuzzy cyber–physical systems (CPSs). Virtual systems that reflect the attacker’s target are established, in which the parameter matrices of virtual systems rely on the different regions where the premise variables (PVs) of the T–S fuzzy CPS and the piecewise fuzzy observer are located at different past instants. Unlike the existing attack policies, a piecewise attack strategy is designed based on the established virtual systems, while the existing ones are required to be nonpiecewise. Furthermore, the $H_{-}/H_{\infty }$ scheme is applied to maximize the impact of the attack on the estimation performance (EP) of the observer while avoiding detected by the detector. A simulation example is applied to verify the effectiveness and advantages of the designed attack scheme.

With the method,a components based production planning and scheduling system in a machine tool company is designed,which is configurable, extensible and reusable and is used to control two different types of workshops. The benefits gained from the modeling method are illustrated by the example.
Ecological Characterization And Simulation OfA Coastal Industrial Area In TheUnited Arab Emirates

This paper presents an overview of the water quality and biological data collected from a coastal industrial site in the United Arab Emirates. Evaluation of the data shows that the area is characterized by high nutrients and low productivity and chlorophyll carbon. Evaluation indicates that further identification of the small-sized phytoplankton is needed. The data is then incorporated in a 3-D ecological numerical model to simulate the lower trophic level prevailing in the area. Hydrodynamic conditions are needed for the model as they were developed in an earlier study. The simulation is done for both the summer and winter seasons utilizing four data sets for parameter stabilization and calibration. Phytoplankton and zooplankton are both simulated with time and space in response to variable effluent fluxes of nutrients and organic matters. Other simulated parameters include nutrients, DOC, POC, COD, and DO. The model proves to be a good tool for evaluating the ecological conditions of coastal areas under different effluent loads.
Grid Dependency Study for the NASA Rotor 37 Compressor Blade

The NASA Rotor 37 has been computed by several authors in the last few years with relative success. The aim of this work is to present a systematic grid dependency study in order to quantify the amount of uncertainty that comes from the grid density. The computational domain is divided onto several regions (i.e. leading edge, trailing edge, shear layer …) and for each of them, the impact of the grid density is investigated.By means of this analysis, substantial improvement has been obtained in the prediction of efficiency and exit angle. On the contrary, the improvement achieved in total pressure and total temperature ratio is less remarkable. It is believed that only after a systematic grid dependency study can the contribution of turbulence modeling, laminar-turbulent transition, and boundary conditions be analyzed with success.Copyright © 1997 by ASME
Pixel-level continuous-time incremental sigma-delta A/D converter for THz sensors

A readout channel based on continuous-time incremental sigma-delta analog-to-digital converter for FET-based terahertz (THz) imaging applications was implemented in a 0.15 μm standard CMOS technology. The designed readout circuit is suitable for implementation in pixel arrays due to its compact size and power consumption. The system-level analysis used to define the modulator parameters and to specify its analog building blocks is presented. The loop filter has been realized by using a Gm-C integrator. Circuit linearization techniques have been implemented to improve the linearity of the transconductor cell and reduce the impact of parasitic capacitances. Moreover, chopper stabilization technique is adopted in the loop filter, significantly reducing the low-frequency flicker noise thereby preserving the Noise Equivalent Power (NEP) of the FET detector within the required specifications of minimum detectable signal. The resulting input referred noise voltage is 87.5 nV/√Hz . The incremental ADC achieves 68-dB peak signal-to-noise-and-distortion-ratio (SNDR), equivalent to 11 bits effective resolution over 1 kHz signal bandwidth at 1 MHz sampling frequency. In order to meet the requirements of large sensor arrays, a first order architecture is realized. This leads to lower area occupancy and power consumption. The readout circuit draws 80 μW of power from a supply voltage of 1.8 V. The channel occupies an area of 90 x 273μm2.
