Abstract
Inspired by the albatross, this paper presents the construction of a dynamic soaring simulation system with distributed pressure sensors. The advantage of our system lies in harvesting energy from the wind shear layer and estimating the wind information using a pressure-based sensor system. Specifically, the dynamic soaring simulation system contains an offline training stage and an online estimation and control stage. In the offline training stage, computational fluid dynamics simulations are conducted and used as the data source. A surrogate model is established to correlate the local flow conditions and the surface pressure at optimal sensor positions. In the online estimation and control stage, through sensing the pressure information, the real-time wind velocity and wind gradient are estimated by the surrogate model trained in the offline stage. Moreover, wind information is adopted in the simulation of dynamic soaring control. In this study, the simulation system was applied to linear and circular path-following tasks. It was found that the dynamic soaring simulation system with distributed pressure sensors provides an acceptable estimation of wind velocity and wind gradient with a certain time delay caused by numerical differentiation.

Abstract
Rice is the number one staple food crop, being eaten by almost all the population in Indonesia. Jajar Legowo Super (Jarwo Super) technology as an approach to improve rice productivity consists of various components of technologies. This study attempts to demonstrate the importance of farmer group empowerment and the implementation of Jarwo Super technology as a strategy to improve rice productivity. A two-year study from 2019 – 2020 was conducted in Cibadak Sub-district, Lebak District, Banten, Indonesia. We combined specific components of rice technology in Jarwo Super, and implemented it in the farmers’ fields. Scheduled assistance through farmer field school (FFS) and field inspections were regularly conducted. The individual farmers’ performance in the implementation of technology and their participation in the FFS were evaluated. Our study showed that the implementation of Jarwo Super significantly improved rice productivity by 34.7% and 35.5% in 2019 and 2020, respectively, as compared to that of regional productivity. The yield performances were highly correlated with both the components of technology as well as farmers’ participation in FFS. We concluded that intensive and continued assisting through extension activities is a key point in delivering technologies to improve rice productivity for better food security.
Chemical properties of acid soil after amelioration of dolomite, coal, and microbes
Authors: Firnia D , Rohmawati I 
Published: February 2022

Abstract
Soil acidity and issues with aluminum (Al) toxicity are typically limiting concerns for agricultural soil utilization. Liming can be used to solve problems with acidic soils. Another option for dealing with acid soil problems is to use coal enriched with sulfate-reduced bacteria (SRB) or Acidithiobacillus ferrooxidans (AF). In a sustainable agriculture system, including coal enriched with SRB or AF into organic fertilizer might increase added value as a source of organic material for plantations. The goal of this research was to see if adding an ameliorant, microbial, or ameliorant enriched microbial to organic fertilizer can boost the added value as a source of organic material for plantations in a sustainable agriculture system. Two acid soils (Ultisols) were investigated, with variances in exchangeable Al concentration. The results showed that the use of a dolomite ameliorant or dolomite enriched AF ICBB 8789 raised pH, Ca, and Mg in the soil. In the soils of Jasinga and Lebak, the treatment of coal enriched with AF ICBB 8789 was more effective in increasing the CEC value. In acid soil from Jasinga West Java and Lebak Banten, a coal or lime ameliorant enriched with SRB could increase the availability of P. In a sustainable agriculture system, coal or coal enriched SRB or AF can potentially increase added value as a source of organic material for agricultures

Published: February 2022

Abstract
Potato is the main vegetable commodity cultivated by farmers in Kerinci Regency and has been supported by appropriate agro-ecosystems, the availability of land areas, labor and market opportunities as well as government endowment. In general, farmers in every season have not fully implemented cultivation technology recommendations. This paper aims to describe the growth and productivity improvement of potato varieties in Kerinci, Jambi. The activity was carried out in Tanjung Bunga Village, Kayu Aro District, Kerinci Region during wet season 2018, involving 3 cooperative farmers and a land area of 0.25 ha which was planted with two varieties namely Granola and Medians. The results showed that the Medians variety gave a higher number of tubers than the Granola variety, but a large number of tubers was obtained from the Granola variety. Therefore, the Granola variety provided a heavier yield of 17.08 kg or equivalent to 22.775.5 kg/ha, while the Medians was only 12.50 kg or 17.862.25 kg/ha. This study was also found three main pests that occurred ie, leaf-miner fly, armyworm, and tuber-miner, whereas late blight disease was caused by Phytophthora infestans simultaneously infecting both varieties. However, conducting the demonstration plots in this season, the Granola variety was more resistant to disease than the Medians variety.

Authors: Hariprasad V , Megalingam A 
Published: February 2022

Abstract
Egg Shell Powder (ESP) and Tungsten Disulphide (WS2) are reinforced on AZ61 magnesium alloy through Friction Stir Process (FSP). The average particle size of ESP and WS2 are 45 μm and 10 μm, respectively. The ESP and WS2 mixed at different weight percentage (80/20, 70/30, 50/50, 30/70 and 20/80). Initially, equally spaced cylindrical holes are drilled on AZ61 alloy and then reinforcement mixture is filled in the holes using a flat head tool to secure the reinforcements. FSP tool pin with threaded profile is used to perform the friction stir process at tool rotation speed of 1000 rpm, 7 kN of axial load and 5 mm minute−1 tool transfers speed. From the micro and macro optical images, the defect free FSPed composite is obtained for the reinforcement combination of AZ61/80ESP/20WS2. The mechanical, tribological and corrosion tests are conducted on FSPed AZ61/80ESP/20WS2 composite and AZ61 base alloy according to ASTM standards. Microhardness increased twice in the nugget zone of FSPed AZ61/80ESP/20WS2 composite compared to the AZ61 base alloy because of grain refinement. The ultimate tensile strength of FSPed AZ61/80ESP/20WS2 composite increased up to 8.3% compared to AZ61 base alloy and showed ductile behaviour during the fracture. Dry wear tests conducted at three different sliding velocities (0.83, 1.7 and 2.5 m s−1) and three different loads (5 N, 10 N and 15 N) by keeping the sliding distance as 1500 m. The results showed an improvement in wear resistance of FSPed AZ61/80ESP/20WS2 composite up to 35% compared to the AZ61 base alloy. SEM images revealed that the wear mechanism changes from adhesive to abrasive under high operating conditions. The results of electrochemical corrosion test revealed that the corrosion rate of the FSPed AZ61/80ESP/20WS2 composite reduced significantly at the nugget zone because of grain refinement and reinforcement addition.
Zinc titanates nanopowders: synthesis and characterization
Authors: Gabal M A , Angari Y M Al 
Published: February 2022

Abstract
Zinc titanates nanopowders viz.; Zn2TiO4, ZnTi3O8 and ZnTiO3 were synthesized through the thermal decomposition course of ZnC2O4.2H2O-TiO2 precursors mixture (1:1 mole ratio), prepared via a new co-precipitation method up to 900 °C. Thermogravimetric measurement (TG) was utilized to characterize the precursors mixture decomposition while x-ray diffraction (XRD), Fourier transform infra-red (FT-IR) were used to characterize the decomposition products as well as the phase transitions at different temperatures. XRD revealed the starting of titanates formation at 700 °C via detecting Zn2TiO4 along with ZnO and TiO2 (anatase) diffraction peaks. By increasing the calcination temperature to 800 °C, the ZnO content vanished with the appearing of Zn2Ti3O8 besides ZnTi2O4 and impurities of TiO2 (anatase). Finally at 900 °C, the Zn2Ti3O8 content was decomposed into ZnTiO3. Nitrogen adsorption-desorption isotherm of the calcined precursors mixture at 900 °C indicated low specific surface area of 7.1 m2 g−1 in accordance with the agglomeration nature estimated via transmission electron microscopy (TEM) study. The conductivity measurements showed semiconducting behavior of the prepared titanates with ferroelectric transition in the range 200 °C–308 °C. The obtained low dielectric value suggests the uses of present titanates as a co-fired ceramic or resonator ceramics.

AbstractIn recent years, we have been witnessing a paradigm shift in computational materials science. In fact, traditional methods, mostly developed in the second half of the XXth century, are being complemented, extended, and sometimes even completely replaced by faster, simpler, and often more accurate approaches. The new approaches, that we collectively label by machine learning, have their origins in the fields of informatics and artificial intelligence, but are making rapid inroads in all other branches of science. With this in mind, this Roadmap article, consisting of multiple contributions from experts across the field, discusses the use of machine learning in materials science, and share perspectives on current and future challenges in problems as diverse as the prediction of materials properties, the construction of force-fields, the development of exchange correlation functionals for density-functional theory, the solution of the many-body problem, and more. In spite of the already numerous and exciting success stories, we are just at the beginning of a long path that will reshape materials science for the many challenges of the XXIth century.
A descriptive report of the rapid implementation of automated MRC-ICU calculations in the EMR of an academic medical center
Authors: Webb Andrew J , Rowe Sandra , Newsome Andrea Sikora 
Published: February 2022

Abstract

Purpose
Numerous clinical scoring tools exist for a variety of patient populations and disease states, but few tools provide information specifically designed for use by critical care pharmacists. The medication regimen complexity–intensive care unit (MRC-ICU) score was designed to provide high-level information about the complexity of critically ill patients’ medication regimens for use by critical care pharmacists. To date, implementation of this score in the electronic medical record (EMR) has not been reported.

Summary
Using an agile project management framework, the MRC-ICU score was rapidly implemented into an academic medical center’s EMR. The score is automatically calculated for all critically ill patients and is available for critical care pharmacists to triage patient review in their individual workflow. Reporting capabilities of the score also allow for granular complexity trending over time and between units, supplementing other objective measures of pharmacist workload.

Conclusion
The MRC-ICU score can be quickly implemented into the EMR for pharmacist use in real time. Future investigations into how pharmacists utilize this information and how to harness reporting capabilities for pharmacist workload assessment are warranted.
Network medicine in ovarian cancer: topological properties to drug discovery

Published: February 2022

AbstractNetwork medicine provides network theoretical tools, methods and properties to study underlying laws governing human interactome to identify disease states and disease complexity leading to drug discovery. Within this framework, we investigated the topological properties of ovarian cancer network (OCN) and the roles of hubs to understand OCN organization to address disease states and complexity. The OCN constructed from the experimentally verified genes exhibits fractal nature in the topological properties with deeply rooted functional communities indicating self-organizing behavior. The network properties at all levels of organization obey one parameter scaling law which lacks centrality lethality rule. We showed that $\langle k\rangle $ can be taken as a scaling parameter, where, power law exponent can be estimated from the ratio of network diameters. The betweenness centrality $C_B$ shows two distinct behaviors one shown by high degree hubs and the other by segregated low degree nodes. The $C_B$ power law exponent is found to connect the exponents of distributions of high and low degree nodes. OCN showed the absence of rich-club formation which leads to the missing of a number of attractors in the network causing formation of weakly tied diverse functional modules to keep optimal network efficiency. In OCN, provincial and connector hubs, which includes identified key regulators, take major responsibility to keep the OCN integrity and organization. Further, most of the key regulators are found to be over expressed and positively correlated with immune infiltrates. Finally, few potential drugs are identified related to the key regulators.

Published: February 2022

Abstract

Background
Promoting wound healing is crucial to restore the vital barrier function of injured skin. Growth factor products including epidermal growth factor (EGF), fibroblast growth factor (FGF) and granulocyte-macrophage colony stimulating factor (GM-CSF) have been used for decades although no systematic evaluation exists regarding their effectiveness and safety issues in treating acute skin wounds. This has resulted in a lack of guidelines and standards for proper application regimes. Therefore, this systematic review and meta-analysis was performed to critically evaluate the effectiveness and safety of these growth factors on skin acute wounds and provide guidelines for application regimes.

Methods
We searched PubMed/Medline (1980–2020), Cochrane Library (1980–2020), Cochrane CENTRAL (from establishment to 2020), ClinicalTrials.gov (from establishment to 2020), Chinese Journal Full-text Database (CNKI, 1994–2020), China Biology Medicine disc (CBM, 1978–2019), Chinese Scientific Journal Database (VIP, 1989–2020) and Wanfang Database (WFDATA, 1980–2019). Randomized controlled trials (RCTs), quasi-RCTs and controlled clinical trials treating patients with acute skin wounds from various causes and with those available growth factors were included.

Results
A total of 7573 papers were identified through database searching; 229 papers including 281 studies were kept after final screening. Administering growth factors significantly shortened the healing time of acute skin wounds, including superficial burn injuries [mean difference (MD) = −3.02; 95% confidence interval (CI):−3.31 ~ −2.74; p &lt; 0.00001], deep burn injuries (MD = −5.63; 95% CI:−7.10 ~ −4.17; p &lt; 0.00001), traumata and surgical wounds (MD = −4.50; 95% CI:−5.55 ~ −3.44; p &lt; 0.00001). Growth factors increased the healing rate of acute skin wounds and decreased scar scores. The incidence of adverse reactions was lower in the growth factor treatment group than in the non-growth factor group.

Conclusions
The studied growth factors not only are effective and safe for managing acute skin wounds, but also accelerate their healing with no severe adverse reactions.

Abstract

OBJECTIVES
The immunogenicity of two-dose severe acute respiratory syndrome coronavirus 2 vaccine is lower among heart transplant (HTx) recipients, compared with the general population. Our aim was to assess the immunogenicity of a third-dose vaccine in HTx recipients.

METHODS
This is a prospective cohort study of HTx recipients who received a third dose of the BNT162b2 vaccine. Immunogenicity was assessed by serum levels of anti-spike immunoglobulin G (S-IgG), taken at baseline and 14–28 days after the third dose. Titres above 50 U/ml were interpreted positive.

RESULTS
We Included 42 HTx recipients at a median age of 65 years [interquartile range (IQR) 58–70]. At baseline, the median of 27 days (IQR 13–42) before the third dose and the median titre of the whole group was 18 U/ml (IQR 4–130). Only 14 patients (33%) were S-IgG seropositive. After the third dose, the proportion of seropositive patients increased significantly to 57% (P = 0.05) and the median titre increased significantly to 633 U/ml (IQR 7–6104, P &lt; 0.0001). Younger age at HTx (OR per 1-year decrease 1.07, P = 0.05), low tacrolimus serum level (OR per 1-unit decrease 2.28, P = 0.02), mammalian target of rapamycin use (OR 13.3, P = 0.003), lack of oral steroids use (OR 4.17, P = 0.04) and lack of calcineurin inhibitor use (71% of responders vs 100% non-responders received calcineurin inhibitors, P = 0.01) were predictors of seropositive result after the third dose. However, no significant association was detected following adjustment for baseline S-IgG titre.

CONCLUSIONS
Third-dose booster of BNT162b2 vaccine significantly increased immunogenicity among HTx recipients who previously received a two-dose vaccine.
Barley: a potential cereal for producing healthy and functional foods
Authors: Geng La , Li Mengdi , Zhang Guoping , Ye Lingzhen 
Published: February 2022

Abstract
Barley is the fourth largest cereal crop in the world. It is mainly used for feeding, beer production and food. Barley is receiving more attention from both agricultural and food scientists because of its special chemical composition and health benefits. In comparison with other cereal crops, including wheat, rice and maize, barley grains are rich in dietary fiber (such as β-glucan) and tocols, which are beneficial to human health. It is well proved that diets rich in those chemicals can provide protection against hypertension, cardiovascular disease, and diabetes. Barley has been widely recognized to have great potential as a healthy or functional food. In this review, we present information about studies on the physical structure of the barley grain and the distribution of its main chemical components, nutrient and functional composition of barley grain and their health benefits, and the approaches of improving and utilizing the nutrient and functional chemicals in barley grain. With the development of processing technologies, functional components in barley grains, especially β-glucan, can be efficiently extracted and concentrated. Moreover, nutrient and functional components in barley grains can be efficiently improved by precise breeding and agronomic approaches. The review highlights the great potential of barley used as healthy and functional foods, and may be instructive for better utilization of barley in food processing.
