Abstract
Aims

To understand the response of alpine meadow to shrub encroachment, we analyzed alpine meadow plant community structure and function and soil properties at different shrub coverage sites in western Sichuan, P.R. China, further providing a reasonable scientific basis to better control or remove the effects of shrub encroachment on local meadow.
Methods

A site with an area of 200 × 200 m along the shrub line was selected as the study area (4300 m a.s.l.) in Yajiageng Valley, Hengduan Mountain, Southwest China. The study area was divided into four treatments. Control, low-, medium- and high -shrub- coverage plots were investigated for community composition, above- ground biomass and belowground biomass were harvested, and root functional traits and soil properties were measured in laboratory in the summer of 2020.
Results

There was no significant difference in the total aboveground biomass among all treatments, however, forb and legume biomass increased, and grass and sedge biomass decreased with increased shrub coverage; Species richness significantly decreased, but diversity and evenness index increased in the medium -shrub -coverage plots; Root biomass at the depth of both 0-10 cm and 10-20 cm significantly decreased in medium- and high -shrub -cover plots; The field capacity, soil total nitrogen (STN) and available nitrogen (AN) concentration were significantly decreased in the medium -shrub -coverage plots, and the total phosphorus (TP) concentration were significantly decreased among all treatments.
Conclusion

The process of shrub encroachment tends to limit the local dominant species and maintain the growth of nondominant species, which further increases the community diversity and maintains the stability of aboveground biomass. Shrub encroachment makes alpine meadow soil became drier and impoverishment and promoted the mineralization of organophosphorus and the dissolution of insoluble inorganic phosphorus, which strengthened the alpine ecosystem nitrogen (N) limit.
Neutron's basic Mass

Abstract
In Quantum Physics the Spin of an elementary particle is defined to be an „intrinsic, inherent“ property. The same to the magnetic moment (μ) due to the spin of charged particles - like Electron (me) and Muon (mu). So the intrinsic spin (S) of the electron entails a magnetic moment. However, a magnetic moment of a charged particle can also be generated by a circular motion of an electric charge (e), forming a current. Hence the „orbital motion of charge“ around a „mass-nucleus“ generates a magnetic moment by Ampère’s law. This concept leads to an alternative way calculating the neutrino mass (mν) while discussing the beta decay of a neutron into fragments: proton, electron, neutrino and kinetic energy - now based on the change of magnetic moments during the process. This alternative calculation gives mν = 0.10(20)eV.

Abstract
Because the traditional computing model can no longer meet the particularity of Internet of Vehicles tasks, aiming at its characteristics of high bandwidth, low latency and high reliability, this paper proposes a resource allocation strategy for Internet of Vehicles using reinforcement learning in edge cloud computing environment. First, a multi-layer resource allocation model for Internet of Vehicles is proposed, which uses the cooperation mode of edge cloud computing servers and roadside units to dynamically coordinate edge computing and content caching. Then, based on the construction of communication model, calculation model and cache model, make full use of idle resources in Internet of Vehicles to minimize network delay under the condition of limited energy consumption. Finally, the optimization goal is solved by two-layer deep Q network model, and the best resource allocation plan is obtained. The simulation results based on the Internet of Vehicles model show that the computational energy consumption and system delay of proposed strategy do not exceed 400J and 600ms respectively. Besides, the overall effect of resource allocation is better than other comparison strategies and it has certain application prospects.
A Method of Identifying Geometric Errors For Machine Tools With 3 Axes Based On a Set of Sine Functions Using Double Ballbar

Published: October 2021

Abstract
Geometric error is an important error source of machine tools. Quick, accurate and convenient measurement of machine tool geometric errors is an urgent need to improve the accuracy of machine tools. Based on the ballbar's circular trajectory test principle, this paper proposes a machine tool error identification method based on a collection of sine functions. Based on the multi-body system theory and the homogeneous coordinate transformation method, a mathematical model of the circular path error and geometric error of the machine tool with 3 axes is established. Using a collection of sine functions to fit geometric errors has a higher fitting accuracy than traditional polynomial function fitting methods. By designing five circular motion trajectories of the same radius with different centers in the test area, and assuming that each geometric error is a collection of sine functions, a parametric model identification model for machine tool geometric errors based on the circular trajectory is derived. The particle swarm algorithm is used to search and solve the various parameters of the sine function collection, and finally 9 linear errors and 5 angular errors of the machine tool are obtained. In order to verify the effectiveness of the method, simulation and test comparison experiments were carried out. The experimental results show that 4 linear errors and 1 angular error of the machine toolscan be effectively obtained. The verification experiment results show that, compared with the measurement results of the laser interferometer, the maximum deviation of the measurement and identification results proposed in this paper is within 2.5 μm.

Abstract
In recent years, information security has become a prime issue of worldwide concern. To improve the validity and proficiency of the image data hiding approach, a piece of state-of-the-art secret information hiding transmission scheme based on morphed face recognition is proposed. In our proposed data hiding approach, a group of morphed face images is produced from an arranged small-scale face image dataset. Then, a morphed face image which is encoded with a secret message is sent to the receiver. The receiver uses powerful and robust deep learning models to recover the secret message by recognizing the parents of the morphed face images. Furthermore, we design two novel Convolutional Neural Network (CNN) architectures (e.g. MFR-Net V1 and MFR-Net V2) to perform morphed face recognition and achieved the highest accuracy compared with existing networks. Additionally, the experimental results show that the proposed schema has higher retrieval capacity and accuracy and it provides better robustness.

Abstract
Background and purpose

Introduction The goal of this study was to retrospectively identify potential risk factors, especially surgical timing, for poor prognosis of ICH.
Methods

Medical records of ICH cases who had undergone surgery between January 2014 and January 2021 were reviewed. The modified Rankin Scale score (MRS) were assigned to ICH subjects at 6 months after attack. The relationships of surgical timing with the risk of unfavorable outcome were identified using the interaction and stratified analyses, generalized additive and logistic regression model. Depending on the results of logistic regression, a nomogram was established and evaluated using a receiver operating characteristic curve analysis, plotted decision curve and calibration curve.
Results

Finally, 53 and 144 cases were enrolled into the favorable and unfavorable outcome group respectively. The cases who underwent surgery at >12h and <36h in the favorable outcome group were more than that in the unfavorable outcome group (p<0.001). When the time to operation room (TOR) was less than 21h, the negative association between TOR and unfavorable outcome was observed in the smoothing spline (OR=0.8, p < 0.001). We developed a nomogram including SBP, GCS, midline shift, hematoma volume and TOR for predicting the unfavorable outcome. The AUC, accuracy, specificity, and sensitivity of nomogram were 0.90, 0.87, 0.72, 0.93 respectively.
Conclusions

The patients who underwent surgery at >12h and <36h were more likely to get favorable outcome. The nomogram including SBP, GCS, midline shift, hematoma volume and TOR was reliable for predicting ICH outcome.
Hydrus-1D simulation of two-stage cross-flow pre-filtration of turbid river water
Authors: Davis Goldie , Ekwue Edwin 
Published: October 2021

Abstract
Simulation is a modus operandi often used for imitating real-world processes. It involves a system and set of assumptions used for computing a numerical model, from which the outcome is an estimate of the true characteristics of how the system behaves. The intention of this research was to investigate the efficiency of fabric in two-stage cross-flow filtration using linen, crepe-backed satin, burlap and cotton fabric filter media. The results from previous pilot-scale experiments performed showed that linen fabric was the most effective medium at retaining particles. In continuation of this research, the aim of this paper was to utilize Hydrus-1D simulation software to simulate cross-flow filtration with fabric filter medium. This was done to further confirm the efficiency of cross-flow filtration, in particular with linen fabric filter media. Simulation entailed investigating fabric water content versus pressure head; bottom pressure head versus time; fabric water storage versus time; and cumulative infiltration versus time with both single and four layers of fabric filter media. Hydrus-1D simulation was productive since it confirmed that cross-flow filtration with linen fabric filter media has the potential of becoming a pre-filtration step in surface water treatment, further adding to the results obtained from previous pilot-scale experiments.
The Inhibitory Effects of Some Artificial Food Colorings on α-amylase and
α-glucosidase: In vitro and In silico Studies

Published: October 2021

Background:
Inhibition of α-amylase and α-glucosidase is considered as an important therapeutic
target to manage type 2 diabetes mellitus (T2DM), reducing postprandial hyperglycemia (PPHG).

Objective:
The present work explored the antidiabetic activities of five artificial food colorings by α-
amylase and α-glucosidase enzyme inhibition in vitro and in Silico.

Methods:
In this study, inhibition of α-amylase and α-glucosidase was evaluated. Further, the interaction
between enzymes (α-amylase and α-glucosidase) and ligands (food colorings) was followed by
QSAR and molecular docking studies.

Results:
The in vitro results obtained show that the blue patent (SIN131) exhibited more potent inhibition
with IC50 values of 0.03± 0.01 mM and 0.014±0.001 mM against α-amylase and α-glucosidase inhibition
respectively compared to acarbose. The QSAR study found a strong correlation between IC50
values with four molecular descriptors. This linear regression confirms that a strong polarity (Apol) and
low hydrophobia (ALogP) favor the inhibitory effect of these colorings toward both enzymes. Also, a
negative role of the number of heavy atoms has been demonstrated in the phenomenon of inhibition of
this enzyme. Finally, the descriptor εlumo (electronic affinity) plays a crucial role on the inhibitory
power of these dyes toward both enzymes by electron transfer. The virtual screening of the inhibition of
α-amylase and α-glucosidase by these colorings, using Molegro Virtual Docker (MVD), allowed us to
obtain stable complexes with interaction energies resulting from the place of hydrogen bonds and several
hydrophobic interactions. However, the sulfonate groups of these colorings can be the major factors
in the inhibition of these enzymes. On the other hand, Rerank Score with the pose are perfectly correlated
(R2> 0.76) to the inhibitory activity of these food colorings measured experimentally.

Conclusion:
The present study suggests that the Blue Patent V (SIN131) effectively acts as α-amylase
and α-glucosidase inhibitor leading to a reduction in starch hydrolysis and eventually to lower glucose
levels.

Entre las especies de mosquitos (Diptera: Culicidae) sinantrópicos que existen en la región de las Américas, tres desempeñan un papel protagónico en la transmisión de enfermedades de importancia médica en países de bajos y medios ingresos (LMIC): Aedes aegypti, Aedes albopictus y Culex quinquefasciatus. Con el objetivo de caracterizar la infestación domiciliar de estos mosquitos, se realizó un estudio entomológico en el municipio de Jutiapa (Guatemala) y Jarabacoa (República Dominicana), ambos incluidos dentro de la clasificación de LMIC. En cada municipio se muestrearon 100 viviendas seleccionadas aleatoriamente; en cada criadero se capturó la mayor cantidad posible de larvas y/o pupas con la ayuda de pipetas Pasteur, bandejas plásticas y botes herméticos. El porcentaje de depósitos con agua infestados por alguna de las especies de culícidos estudiada fue similar en ambos municipios (Jutiapa = 27.9 %, Jarabacoa = 20.0 %); entre estos predominaron los ubicados en el peri-domicilio (Jutiapa = 76.3 %, Jarabacoa = 93.7 %) en depósitos permanentes y útiles (Jutiapa = 79.6 %, Jarabacoa = 56.9 %). De forma general, Ae. aegypti fue la especie que más depósitos colonizó (Jutiapa = 92, Jarabacoa = 84), en cohabitación o no con otras especies. Los resultados refuerzan la necesidad de desarrollar estrategias de comunicación y participación comunitaria contextualizadas a las características de cada territorio y especie, así como direccionar los esfuerzos hacia el control doméstico, teniendo en cuenta sus contribuciones a la efectividad y sostenibilidad del manejo integrado de culícidos en estos y otros municipios con características similares.

Introducción: la osteoporosis (OP) es una enfermedad de alta significancia a nivel mundial que se caracteriza por cambios en la microarquitectura de la médula ósea (MO) y puede presentarse dentro de algunos trastornos hematológicos.
Objetivo: realizar una revisión del tema de la osteoporosis y describir la relación que tiene la OP con alteraciones hematológicas como causas o consecuencias.
Métodos: se realizó la búsqueda de información en bases de datos: PubMed, Science-Direct y Scielo mediante palabras clave como: “osteoporosis”, “hematopoyesis”, “médula ósea” y “enfermedades hematológicas” en español e inglés. De la búsqueda fueron consultados 45 artículos.
Conclusión: la OP es una enfermedad que se presenta por lo general en personas de edad avanzada, está directamente asociada al envejecimiento o, de manera secundaria, a otros procesos patológicos. Dentro de la mayoría de los trastornos hematológicos se puede evidenciar la presencia de OP, por lo que es importante tener esta enfermedad dentro de los componentes a tratar en pacientes con hemofilia, linfoma, β talasemia y la enfermedad de células falciformes. Por último, el uso de ayudas diagnósticas es importante para hacer seguimiento y control a las alteraciones hematológicas y de igual forma a la progresión de la osteoporosis, con el fin de evitar la aparición de fracturas en los pacientes con estas enfermedades.
