A global meta‐analysis of indicators for assessing forest soil quality through comparison between paired plantations versus natural forests

Soil quality is defined as the capacity of soil to sustain biological productivity and healthy environments. More than 30 physical, chemical, and microbial properties have been used to assess soil quality status. However, using specific properties to represent forest soil quality remains ambiguous. Here, we conducted a meta‐analysis of paired natural and plantation forests using 104 articles and 26 soil indices to evaluate soil quality indicators. Principal component analysis (PCA) and correlation analysis were used to choose a minimum dataset (MDS) of soil quality indicators. Significant differences in 16 indices of soil properties, including 1 physical, 5 chemical and 10 microbial properties, were found between soils in natural versus plantation forests. The PCA and correlation analysis indicated that 7 indices, including total carbon (C) and nitrogen (N), microbial biomass C (MBC) and N (MBN), fungal biomass, bacterial biomass, and hydrolytic enzymes, can be used to establish an MDS that explains 76.8% of the data variation. Based on the MDS, total C and N, MBC, MBN, fungal biomass, bacterial biomass and hydrolytic enzymes contribute 17.9%, 14.9%, 22.2%, 16.7%, 15.2%, 8.3%, and 4.8% to the soil quality, respectively. The climate, stand age and tree species affect the intensity of variation in these 7 soil indicators, not the variation direction of these soil indicators. Our study indicates that soil C and N values and microbial properties are important forest soil quality indicators and that the intensity of variation in these soil indicators depends on the climate, stand age and tree species planted.
Study on the Mechanism of Acori Graminei Rhizoma in the Treatment of Alzheimer's Disease Based on Network Pharmacology and Molecular Docking

Alzheimer's disease is a common neurodegenerative disease in the elderly. This study explored the curative effect and possible mechanism of Acori graminei rhizoma on Alzheimer's disease. In this paper, 8 active components of Acori graminei rhizoma were collected by consulting literature and using the TCMSP database, and 272 targets were screened using the PubChem and Swiss Target Prediction databases. Introduce it into the software of Cytoscape 3.7. 2 and establish the graph of “drug-active ingredient-ingredient target. ” A total of 276 AD targets were obtained from OMIM, Gene Cards, and DisGeNET databases. Import the intersection targets of drugs and diseases into STRING database for enrichment analysis, and build PPI network in the Cytoscape 3.7. 2 software, whose core targets involve APP, AMPK, NOS3, etc. GO analysis and KEGG analysis showed that there were 195 GO items and 30 AD-related pathways, including Alzheimer's disease pathway, serotonin synapse, estrogen signaling pathway, dopaminergic synapse, and PI3K-Akt signaling pathway. Finally, molecular docking was carried out to verify the binding ability between Acori graminei rhizoma and core genes. Our results predict that Acori graminei rhizoma can treat AD mainly by mediating Alzheimer's signal pathway, thus reducing the production of Aβ, inhibiting the hyperphosphorylation of tau protein, regulating neurotrophic factors, and regulating the activity of kinase to change the function of the receptor.
Contact and force control in microassembly

This paper aims at advancing micromanipulation technology with in-situ PVDF piezoelectric force sensing and control during microassembly and packaging process. To allow close monitoring of magnitude and direction of forces (surface, friction, and assembly force) acting on micro devices during manipulation, the polyvinylidene fluoride (PVDF) is used to fabricate highly sensitive 1-D and 2-D force sensors for assembly of micro devices. By using the designed force sensors with the effective signal processing techniques, the contact force/impact signal can be obtained desirably so that it greatly improves the reliability of force regulation in microassembly. Moreover, based on a new sensor-referenced control method, the force control had been implemented by employing a micromanipulator system equipped with the force sensor and its results verify the effectiveness of sensor model as well as the performance of force feedback and control system. Ultimately the technology will provide a critical and major step towards the development of automated manufacturing processes for batch assembly of micro devices.
Reducing Organizational Anomie in Light of Entrepreneurial Behavior

The research aims to clarify the role of the main variable represented by the four dimensions of entrepreneurial behavior (creative, risk-taking, seizing opportunities, proactivity), in Reducing the dependent variable of organizational anomie with the dimensions (Organizational Normlessness, Organizational Cynicism, Organizational Valuelessness). The experimental, analytical method was adopted in the completion of the research, and an intentional sample of (162) individuals in the administrative levels (higher and middle) in the factory was taken. The questionnaire was also adopted as the main tool, which included (54) paragraphs, as (162) forms were distributed and 144 were retrieved from them, valid for statistical analysis from the total forms distributed to the factory. The most important results of the research showed the effect of the dimensions of entrepreneurial behavior and directly on organizational anomie, and that the relationship of entrepreneurial behavior and at the total level was positive with organizational anomie. They ignore the values ​​of work to achieve their goals, as well as the existence of a spirit of cooperation and one team among workers in the factory
Co‐ordinated elevational diversity patterns for soil bacteria, fungi, and plants in alkaline soils of arid northwestern China

Plants often show remarkable elevational distribution patterns in arid‐montane ecosystems. However, it is not clear if soil microbes follow elevational diversity patterns, even though they represent the majority of biodiversity and drive varieties of ecological processes. Here, we conducted a survey of fungal and bacterial communities across an elevational gradient from 2350 to 3850 m in a typical mountainous grassland of arid northwestern China. Our results revealed co‐ordinated alpha and beta diversity patterns for soil microbes and plants along the elevational gradient, and the richness and Shannon diversity of bacteria, fungi, and plants exhibited a unimodal elevational pattern. The unimodal diversity pattern for soil microbes was further confirmed by the shifts in the relative abundance of dominant bacterial phyla (Actinobacteria, Firmicutes and Nitrospirae) and fungal phyla (Zygomycota) along the elevational gradient. Soil variables (soil pH, organic carbon, total nitrogen, available phosphorus, and nitrate nitrogen) explained the largest proportion of the variability in both bacterial and fungal communities, followed by plant (richness and Shannon diversity) and climatic (mean annual temperature and precipitation) variables. These environmental factors together explained a larger proportion of variability in bacterial communities (54.88%) than in fungal communities (24.15%). Our results strongly supported the existence of co‐ordinated elevational diversity patterns for soil microbes and plants in arid‐montane ecosystems, and highlighted that the importance of soil pH in microbial elevational patterns was also apparently in alkaline soils.
A qualitative examination of safety-related compliance challenges for global manufacturing

Globally operating machine manufacturing companies need practices for recognising local safety requirements, as well as for designing the products for, and delivering them to, wider markets. This study aimed to determine (1) companies’ product delivery strategies for managing product safety compliance and conformity in their supply chains, (2) the problems that arise in managing the product safety-related requirements and (3) how companies tackle these problems. The study comprised interviews with 25 representatives of 2 large internationally operating European companies manufacturing machines for use at work. The companies’ strategies for decoupling the local safety requirements from their standard products covered make-to-stock, assemble-to-order, make-to-order and engineering-to-order. The problems were experienced mostly in systematic discovering and processing of the requirements, responsibility issues and unequal practices within global organisation. To tackle these problems, a company must have tools and practices to manage the information needs and understand the concepts of product delivery strategies. Relevance to human factors/ergonomics theory Companies must have tools to integrate the design of safe and ergonomic products into engineering design process. This article discusses the safety design of machines intended for use at work from the compliance management and supply chain management perspectives. The topics are not new per se, but they can create a novel combination in the safety research for the scientific community. This article provides novel information for the safety researchers regarding safety-related challenges within global business as well as the applicability of adapted theories in safety research. As a conclusion, the authors give recommendations to better tackle the issue of manufacturing-compliant products cost-effectively for differing customers and markets.
Analysis of a gap-coupled multi-layer patch antenna

A multi-layer patch antenna that is fed by a gap discontinuity within a microstrip feed line is investigated. The feed line is located on the lower layer of the structure, while a rectangular patch is centred above the gap discontinuity on the upper layer. The structure is analyzed by the moment method in the spatial domain, employing a matched load simulation technique. Comparison with experimental results indicate that this numerical approach accurately predicts the antenna's characteristics and is also a useful model for design purposes. <<ETX>>

THE ALBANIAN ECONOMY IN THE STOCK MARKET PERSPECTIVE

Since the origin of the capitalist economic system, Albania suffers from a shrinking financial system. The financial system lacks what is perhaps the most important and dynamic part in developed economies: a capital market. It is an important element for the country's economic and financial development, as it is a very competitive alternative to the banking sector, reducing intermediation costs for businesses and all economic operators by enabling cheaper alternatives to fund the activity. Today, the banking system has almost exhausted opportunities to be a business financing promoter. And this is the stage where the Albanian economy has come to. Businesses cannot meet all the financing needs of the banking system, while on the other hand, there are individuals who, at the moment, have little choice of investment of their savings. Interest rates, both for bank deposits and government securities, have already reached an extremely low level and are not at all attractive for individual investors, which makes them look for far more attractive investment alternatives. In this way the scholarship will bring an alternative that individuals can invest savings in shares or other securities of companies that will be interested in trading in Albania thus developing the capital market and taking advantage of all the economic benefits that it brings. In this paper, we will firstly address the concept of the capital market and the elements that shape it as well as its development in Albania. The main purpose of this paper is to identify the problems faced by Tirana's former scholarship, to study the situation and the current opportunities of the Albanian economy to develop this structure of the capital market, namely the stock exchange, and to create a stock index model with which Albania can develop this structure and why not be represented in the regional and international markets.
Measurement of contact soil pressure in physical modelling of soil–structure interaction

Meaningful measurement of contact soil pressure at the interface of a structural boundary has been a cause of frustration to experimentalists in the field of soil mechanics and soil–structure interaction. The difficulty stems from the fact that most sensing systems involve compliance, which induces a local redistribution of pressure in the soil mass. In effect, the attempt to monitor soil pressure ruins the measurement. The paper uses a concept called the ‘null soil pressure system’, which is an active sensing system requiring that the sensing element be continuously and stringently maintained in an un-deflected state. Results illustrate that the nulling pressure required to maintain the membrane in the un-deflected state is in a 1:1 ratio with the applied soil pressure, and is independent of soil type, particle size and particle arrangement. No hysteresis is noted between loading and unloading, and additional loading cycles align with that of the first loading cycle. Relevance of the system within the re.
Calibration of Nodal Demand in Water Distribution Systems

This paper presents an optimization methodology to calibrate the nodal demand in the model of water supply distribution systems. The matrix analysis has been carried out to get the sensitive coefficients matrix for the model of water distribution systems. Singular value decomposition is applied to calculate search director of optimization by solving the sensitive coefficients matrix, which is more efficient than the finite-difference method. Two cases are used to show the performance of this algorithm. The first case is a hypothetical water distribution network showing the calculation of the optimization vector. The second case is the application of real-life water distribution system in Hangzhou, China, which shows the determination of the cutoff singular value and the search step size in one-dimensional search. The calibrated model has been also validated using the measured data. The results have shown that the proposed algorithm is reliable and effective in real-time system.
One-Year Survival for Adult Venoarterial Extracorporeal Membrane Oxygenation Patients Requiring Renal-Replacement Therapy.

OBJECTIVES Acute kidney injury (AKI) and chronic kidney disease (CKD) previously have been associated with in-hospital and long-term mortality of patients undergoing support with venoarterial extracorporeal membrane oxygenation (VA-ECMO). Patient selection criteria and survival prediction scores for VA-ECMO often include AKI or CKD, but exclude patients requiring renal replacement therapy (RRT). The need for RRT in ECMO patients is associated with increased intensive unit care and in-hospital mortality. The effect RRT has on mortality beyond hospital survival is not well-reported. The authors hypothesized that the timing of initiation (pre-ECMO v during ECMO) of RRT can have a significant impact on short- and long-term mortality. DESIGN The authors categorized patients into 3 groups: those receiving RRT before initiation of ECMO, those initiated on RRT while on ECMO, and those who did not need RRT while on ECMO. The authors compared survival to decannulation, 30 days and 1 year between the 3 groups. A multivariate survival analysis also was conducted. SETTING This was a single center retrospective review of all patients receiving VA-ECMO. PARTICIPANTS A total of 347 adult VA-ECMO extracorporeal membrane oxygenation patients. INTERVENTIONS None, retrospective. MEASUREMENTS AND MAIN RESULTS The authors' cohort included 347 total patients, 39 required RRT before ECMO, 139 while on ECMO, and 169 did not require RRT while on ECMO. If RRT was initiated before ECMO, survival to decannulation was 48.72%, 46.6% if RRT was initiated on ECMO, and 73.96% for patients who did not need RRT while on ECMO. One-year survival was 25.64%, 23.74%, and 46.75%, respectively. There was no significant difference in survival between patients initiated on RRT before ECMO and those who required RRT while on ECMO. CONCLUSIONS The authors demonstrated that the need for RRT before or while on ECMO has reduced short- and long-term survival when compared with those who did not need RRT while on ECMO. The authors believe that RRT is a marker for severe multiorgan failure and that, despite the benefits of RRT, high mortality will occur. This lack of mortality difference between patients previously on RRT and those newly requiring RRT may help clinicians in deciding to initiate ECMO for patients previously on RRT. Further investigation into complication rates between the groups is required.
Compact printed double-folded inverted-L antenna for long-range RFID handheld reader

A novel compact printed double-folded inverted-L antenna is presented. The radiator is modified from a printed inverted-L antenna by extending and folding its radiated arm. A unidirectional radiation pattern is obtained as the radiator is mounted on a vertical printed rectangular ground. A slit etched on the ground of proper length and position is used to improve antenna directivity and suppress backward radiation. Measured results indicate that the proposed antenna has a good impedance characteristic (9% for return loss less than 10 dB), excellent front-to-back ratio and forward gain of 5.09 dBi. The antenna is applicable for long-range RFID handheld reader application.
A Synthesis of Practical and Appropriate Instrumentation Use for Accelerated Pavement Testing in the United States

Pavement testing facilities can be utilized to help with the integration of the new Mechanistic-Empirical Pavement Design Guide (MEPDG). One way test facilities are doing this is by embedding instrumentation, such as strain gauges and pressure plates, in pavement structures to measure pavement responses under loading. As new facilities are being constructed or reconstructed, it is important that the instrumentation chosen for research at the facility is appropriate and reliable. Accelerated Pavement Testing (APT) facilities have come together through the Consortium of Accelerated Pavement Testers to help develop practical and appropriate instrumentation uses based on positive and negative experiences at various facilities. Using this insight, a facility undergoing redesign or a new facility might be able to answer some of the following questions before designing its instrumentation scheme. What types of strain gauges are appropriate for what we are trying to determine? What gauges are other facilities using so our results might be comparable to theirs? If a facility were determining whether thermistors are advantageous over thermocouples, it would be important to realize it is difficult to install thermistors horizontally pre-construction; however, these instruments can be installed post-construction vertically in the pavement. The difficulty with this scenario is determining the tip depth of the device. Using experiences from other successful APT facilities to bolster success at other facilities will only increase the amount of valuable findings and help make APTs more profitable.
A new small signal modeling of average current mode control

A new small signal modeling of an average current mode control scheme is proposed. In order to analyze the characteristics of the control scheme, the discrete and continuous time small signal models are derived. The derivation mainly comes from the analysis of the sampling effect presented in the current control loop. By the mathematical interpretation of a practical sampler representing the sampling effect of a current control loop, the small signal models of an average current mode control can be easily derived. The instability of the current control loop, which gives rise to the subharmonic oscillation, can be identified by the proposed models. To show the usefulness of the proposed models, the simulation and experiment are carried out. The results show that the predicted results by the proposed model are much better agreed with the measured ones than that of the conventional model, even though the high gain of the compensation network of a current control loop is employed.
Numerical Simulation of Wave Overtopping Based on DualSPHysics

To obtain a more detailed description of wave overtopping, a 2-D numerical wave tank is presented based on an open-source SPH platform named DualSPHysics, using a source generation and absorption technology suited for SPH methods with analytical relaxation approach. Numerical simulation of regular wave run-up and overtopping on typical sloping dikes is carried out and satisfactory agreements are shown between numerical results and experimental data. Another overtopping simulation of regular wave is conducted against six different types of seawalls (vertical wall, curved wall, recurved wall, 1:3 slope with smooth face, 1:1.5 slope with smooth face and 1:1.5 slope with stepped-face), which represents the details of various breaking waves interacting with different seawalls, and the average deviation of wave overtopping rate is 6.8%.
Using the passively mode-locked soliton fiber laser linear cavity to investigate transparent media

We present a few experimental investigations of the passively mode-locked soliton fiber laser using two saturable absorbers to mode-lock the laser in order to underline the laser sensitivity at the change of sample propagation media. In this case the passively mode-locked fiber laser works like an opto-optic transducer, which has at the input optical parameters of the sample media and generates at the output different types of solitonic pulses which are related to the input parameters. In order to enhance the laser stability we try to compensate the errors by using a differential method.
