AbstractA novel implementation of an economical, self-sustainable and environmentally friendly solution for tight gas field production monitoring in a remote location in Tierra Del Fuego, allows early-stage production measurements necessary in the unconventional reservoir analysis for the field recovery process optimization.This innovative solution is based on the development of a portable skid designed for production test measurement in a multi-well pad, that combine a multiport selector valve and a multiphase flow meter, making possible to remotely select a well to measure and transfer flow data in real time. The commands for the well selection and the data transmission can be done via satellite with an encrypted software directly from the Operator's office. A PhotoVoltaic (PV) solar panel was developed to provide a reliable self-sufficient power for the entire system from 100% clean energy.Located in Chile's Tierra del Fuego region, the Magallanes Basin comprises two main structural regions: a normal faulted eastern region and a thrust faulted western area. These remote tight gas fields undergoing rapid decline are big challenges to explore, develop and produce economically. They demand a close initial surveillance through timely production tests to acquire representative data, which allows consolidation of a reservoir analysis and development methodologies to optimize ultimate and cost-effective recovery. An innovated approach was successful implemented for production monitoring using the Multiphase Measurement Skid, which provided the required data quality and frequency along with flexibility to perform production test in multiple wells, all remotely controlled from the Operator's office. The entire system is self-sufficient and powered by solar panels designed, which brings sustainability avoiding the use of generator and dealing with fuel logistics making this solution environmentally friendly carbon-free emission.Such sustainable and self-sufficient solution to monitor single to multiple wells (up to eight), combines an automated multiport valve system with multiphase measurement technology for remote operations. Its operation is simple and efficient, amd it provides a continuous data stream of well test information to the production and reservoir engineers managing the field.

Abstract
Humanity is approaching an important transition - from the era of expert knowledge to the era of data. When it comes to understanding the future, we are all like preschoolers. With a mixture of childish surprise and adult anxiety, we try to look into this future and see many questions that have no answers. We want to understand how the development of remote working will affect our work and the meaning of life, and find out how people will benefit from using this incredible way of working. If remote working is universal and are there room for improvement for managers in this new reality. Unfortunately, there is no crystal ball to show us the future. This uncertainty makes our questions and attempts to find answers to them all the more important. This paper is one such attempt. Hopefully this paper will shed some light on challenges of remote working in this new reality, as well as nudge researchers into new discussions on this topic.

Abstract
BackgroundTo identify the association between the severity of prenatally diagnosed abnormalities and parental information about pregnancy termination and identify demographic and clinical variables influencing the parental decision. MethodsAn observational cohort study of fetuses diagnosed with an abnormality in the prenatal screening program between 2014 and 2016 in Denmark. We categorized the abnormalities in five long-term prognosis groups, and the association to the doctor's information about termination was described. We tested the association between demographic and clinical variables and the parental decision using univariate and multivariate statistical analysis.ResultsThree hundred twenty fetuses were diagnosed with an abnormality. In 67% of these cases, the parents were informed about termination. All parents were informed in cases with a lethal prognosis, 98% with genetic disorders, 96% with poor, 69% with uncertain, and 12% with a good prognosis. Of these parents, 92% choose to terminate. The long-term prognosis of the abnormalities was the only significant factor in the parental decision-making process.ConclusionsDoctors mainly informed parents about pregnancy termination for conditions with a poor or lethal long-term prognosis or chromosomal abnormalities. The severity of the abnormalities was the only significant factor associated with the parental decision to terminate the pregnancy.

Authors: Cao Long-Yao , Cheng Si , Lin Lu , Chen Ming-Xin 
Published: March 2022

Abstract
Background: The controlling nutritional status (CONUT) score and prognostic nutrition index (PNI) are immune-nutritional biomarkers that are related to clinical prognosis. Previous studies have reported using them to predict the prognosis of traumatic brain injury, tumours and other diseases. The purpose of this study was to evaluate the relationship between the PNI and CONUT score and the one-year prognosis of patients with spinal tuberculosis (STB).Methods: In this study, the clinical characteristics of 80 patients with STB who underwent debridement and internal fixation at our institution between 2010 and 2020 were retrospectively analysed. According to the receiver operating characteristic (ROC) curve, patients were divided into two groups: a high CONUT group and a low CONUT group. Patients were also divided into a high PNI group and a low PNI group. One-year postoperative prognosis was evaluated by the clinical cure standard.Results: Patients in the favourable group were younger and had a lower rate of pneumonia and urinary tract infection, higher PNI and lower CONUT score than those in the favourable group (P < 0.05). There was an obvious correlation between the PNI and CONUT score (r =-0.884, P < 0.05). The areas under the curve (AUCs) of the CONUT score and PNI for predicting unfavourable prognosis were 0.888 (95% CI: 0.808-0.943, P < 0.001) and 0.896 (95% CI: 0.818-0.949, P < 0.001), respectively. The adjusted odds ratios (ORs) of the CONUT score and PNI for predicting unfavourable outcomes were 2.583 (95% CI: 1.599-4.171, P < 0.001) and 0.680 (95% CI: 0.558-0.828, P < 0.001), respectively.Conclusion: Higher CONUT scores and a lower PNI were associated with adverse outcomes in patients with spinal tuberculosis, and the CONUT score and PNI might be independent predictors of adverse outcomes of spinal tuberculosis postoperatively.

Abstract
NH3 from farmland has serious impacts on human health and ecosystems. To reduce NH3 volatilization and increase yield, biochar is applied. A field experiment was carried out to study NH3 volatilization loss, and summer maize yield was analysed under different irrigation schemes with different amounts of biochar. Two irrigation schemes, I1 (67.5 mm) and I2 (121.5 mm), were set up according to the irrigation habits of local producers. Three biochar application rates were selected: C1 (0 t ha-1), C2 (20 t ha-1) and C3 (40 t ha-1). The relationship between NH3 volatilization and influencing factors, including NH4+-N concentration, NO3--N concentration, pH in the 0~20 cm soil layer and temperature, was investigated. The results showed that the yield significantly (p<0.05) increased by 17.27%~46.67% after applying biochar. Compared with C1, NH3 volatilization significantly (p<0.05) decreased by 28.98%~31.63% in C2, while that in C3 significantly (p<0.05) increased by 22.64%~73.87%. The effects of biochar on NH3 volatilization were consistent under different irrigation conditions. Compared to I1, I2 not only increased the yield of summer corn but also increased the risk of NH3 volatilization and leaching. NH3 volatilization was positively correlated with NH4+-N concentration, pH and temperature, but it was negatively correlated with NO3--N concentration. These results suggest that the optimal application amount of biochar for summer maize ranges from 14.59 t ha-1 to 17.19 t ha-1 in the study area.

Published: March 2022

Abstract
Background
The age of first birth corresponds to the age of the mother giving birth to the first child. The study aims at access the determinants of timing to age at first birth among Ethiopian women.
Methods
The data for this study was extracted from the published reports of Ethiopian Demographic and Health Survey. The study used15, 683 women aged 15–49 years from nine regions and two city administrations. Cox Proportional hazards model was used for identifying factors associated with age at first birth.
Results
The median time of age at first birth for Ethiopian women was22 years with 95% CI; (21.82, 22.18). Multivariable Cox Proportional Hazards Model shows that region, place of residence, education, wealth index, religion, work status, age at first marriage, age at first sex, and use of contraceptives have significant effects on the age at first birth at 5% level of significance. From region category, Amhara region (p-value = 0.398), Benishangul Gumuz(p-value = 0.112) Region, and Gambella region(p-value = 0.062) were not significant at 5% level of significance.
Conclusions
The age at first birth was positively correlated with the age at first sexual intercourse. A woman who has sexual intercourse much earlier gives birth earlier than a woman who is late for first intercourse.

Published: March 2022

Abstract
Detecting communities in complex networks is of paramount importance, and its wide range of real-life applications in various areas has caused a lot of attention to be paid to it, and many efforts have been made to have efficient and accurate algorithms for this purpose. In this paper, we proposed a non-cooperative game theoretic-based algorithm that is able to detect overlapping communities. In this algorithm, nodes are regarded as players, and communities are assumed to be groups of players with similar strategies. Our two-phase algorithm detects communities and the overlapping nodes in separate phases that, while increasing the accuracy, especially in detecting overlapping nodes, brings about higher algorithm speed. Moreover, there is no need for setting parameters regarding the size or number of communities, and the absence of any stochastic process caused this algorithm to be stable. By appropriately adjusting stop criteria, our algorithm can be categorized among those with linear time complexity, making it highly scalable for large networks. Experiments on synthetic and real-world networks demonstrate our algorithm's good performance compared to similar algorithms in terms of detected overlapping nodes, detected communities size distribution, modularity, and normalized mutual information.

Published: March 2022

Abstract
Background
There is no consensus on the optimal secondary antifungal prophylaxis (SAP) regimen in patients receiving allogeneic hematopoietic stem cell transplantation (allo-HSCT). The purpose of this study was to evaluate the efficacy and safety of posaconazole in the secondary prophylaxis of invasive fungal disease (IFD) in patients with allo-HSCT.
Methods
We retrospectively reviewed clinical data from prior IFD patients who received posaconazole as systemic antifungal prophylaxis between June 2016 and January 2021, with a follow-up period of 1 year after HSCT. The clinical outcomes of patients with a history of IFD (n = 30) and those without IFD (n = 93) were compared.
Results
The 1-year cumulative incidence of prophylaxis failure was 44.1% in the group without prior IFD and 50.0% in the group with a past history of IFD (p = 0.470). The cumulative incidence of confirmed, probable or possible IFD within 1 year after allo-HSCT was 15.4% in the group without prior IFD and 25.9% in the group with a past history of IFD (p = 0.148). Two risk factors for the develop of post-transplantation IFD of posaconazole prophylaxis were found, namely, cytomegalovirus disease and steroid treatment for more than 90 days after transplantation. A similar overall survival can be achieved between patients with a prior IFD and those free from a history of IFD.
Conclusions
Posaconazole appears to be a viable alternative to SAP in appropriately selected patients for allo-HSCT.
An Efficient Five-lncRNA Signature for Lung Adenocarcinoma Prognosis and Its Overall Survival Prediction
Authors: Liang Jiali , Jin Weifeng , Xu Huaping 
Published: March 2022

Abstract
Background
Lung adenocarcinoma (LUAD) is a sex-biased and easily metastatic malignant disease. A signature based on 5 long non-coding RNAs (lncRNAs) has been established to promote the overall survival (OS) prediction effect on LUAD.
Methods
The RNA expression profiles of LUAD patients were obtained from The Cancer Genome Atlas. OS-associated lncRNAs were identified based on the differential expression analysis between LUAD and normal samples followed by survival analysis, univariate and multivariate Cox proportional hazards regression analyses. Prognostic lncRNA with sex dimorphism was determined based on the analysis of expression between men and women. Functional enrichment analysis of the Gene Ontology (GO) terms and the Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways was performed to explore the possible mechanisms of 5-lncRNA signatures.
Results
A 5-lncRNA signature (composed of AC068228.1, SATB2-AS1, LINC01843, AC026355.1, and AL606489.1) was found to be effective in predicting high-risk LUAD patients as well as applicable to female and male subgroups and < 65-year and ≥ 65-year age subgroups. The forecasted effect of the 5-lncRNA signature was more efficient and stable than the TNM stage and other clinical risk factors (such as sex and age). Functional enrichment analysis revealed that the mRNA co-expressed with these five OS-related lncRNAs was associated with RNA regulation within the nucleus. AL606489.1 demonstrated a sexual dimorphism that may be associated with microtubule activity.
Conclusion
Our 5-lncRNA signature could efficaciously predict the OS of LUAD patients. AL606489.1 demonstrated gender dimorphism, which provides a new direction for mechanistic studies on sexual dimorphism.

Published: March 2022

Abstract
China’s rapid green growth has resulted in banking sector performance, human capital, and green innovation. This study examines the effect of banking sector performance, education, and green innovation on green growth based in China from 1996 to 2020 by using ARDL. Findings show that banking sector performance (such as market capitalization and banks assets) has significantly enhanced green growth in long-run. The results reveal that education and green innovation foster green growth in China in long-run. We also find short-run market capitalization and education positive effects in green growth. Moreover, in short-run and long-run, trade and renewable energy consumption have a positive effect on green growth. Our empirical consequences provide vital policy implications for promoting green growth in China.

Published: March 2022

Abstract
Background: This retrospective study introduced an alternative treatment of types A2, A3, and B1 distal radius fractures using percutaneous pinning with cemented K-wire frame. Methods: From January 2017 to January 2020, 78 patients with distal radius fractures were treated with percutaneous pinning and cemented K-wire frame. There were 14 male patients and 4 female patients. There were types A2 (n=10), A3 (n=46), and B1 (n=22) fractures. X-rays were taken immediately after surgery and after bone healing. Wrist function was assessed with Mayo Wrist Score to assess wrist function (90–100, excellent; 80–90, good; 60–80, satisfactory; below 60, poor). Patient satisfaction on the upper limb was assessed using the 10-cm visual analog scale. Results: The data showed the fragments were kept in place without significant redisplacment (P>0.05). No wire loosening was found. All K-wires were kept in place without bone lessening. Fixation failure or osteomyelitis was not observed in this series. Bone healing was achieved in all patients at a mean of 4.5 months (range, 4 to 8 months). Follow-ups lasted for a mean of 27 months (range, 24 to 33 months). The mean score of wrist function was 97 (range, 91 to 100), including 66 excellent and 12 good results. The mean patient satisfaction was 10 cm (range, 8 to 10 cm).Conclusions: Percutaneous pinning with cemented K-wire frame is a safe and preferred choice for the treatment of types A2, A3, and B1 distal radius fractures. The frame provides support to prevent wire migration. The fixation is a minimally invasive technique that is easy to perform. Level of Evidence: Therapeutic study, Level IVa.
Predicting Ionospheric Precursors Before Large Earthquakes Using Neural Network Computing and the Potential Development of an Earthquake Early Warning System
Authors: Lin Jyh-Woei 
Published: March 2022

Abstract
Total electron content (TEC) precursors of the Chi-Chi Earthquake, which occurred in Taiwan at 01:47:15 on September 21, 1999 (Taiwan Standard Time, TST), with its epicenter at 23.85° N and 120.82° E, a Richter magnitude (ML) of 7.3 (a moment magnitude (Mw) of 7.6), and a focal depth of 8.00 km, were detected 1, 3, and 4 days before the earthquake using two backpropagation neural network (BPNN) models. These results are consistent with the analysis results of Liu et al. (2001) and Lin (2010). Another TEC precursor was detected on May 13, 2003 (TST), 2 days before the earthquake on May 15, 2003 (TST), with an ML of 5.21. The two BPNN models were to be verified for stability and reliability after performing cross-validation and evaluating the variance in the learning process. For this, the result of the analyzed method can serve as a real-time TEC predicted system for giving any future time as inputs of the two BPNN models. Hence, an earthquake early warning (EEW) system is performable.

Abstract
Cooking oil fumes (COFs) represent a major indoor environmental pollutant and exhibit potent mutagenic or carcinogenic health effects caused by containing various heterocyclic aromatic amines (HAAs) and long-chain aldehydes. Despite some evaluation of the relationship between cumulative exposure to COFs and lung cancer, mainly focused on high concentration exposure to cancer cells, and cell damage of HAAs and aldehydes with low dose exposure to healthy cells has been unadequately investigated. Herein, we have firstly scrutinized the toxicity of these three typical compounds of HAAs and aldehyde emission from COFs, which includes heterocyclic amine 2-amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP), 3,8-dimethylammidazo[4,5-f]quinoxalin-2-amine (MeIQx) and trans, trans-2,4-decadienal (TDA)) to both in vitro and in vivo. In vitro experiments revealed that the PhIP, MeIQx and TDA aerosol particles had negligible toxicity to cancer cells (A549 and HepG-2) but strong cytotoxicity to normal healthy cells (HelF and L02) under 0.5-4 µg/mL low dose exposure based on the reactive oxygen species (ROS) mechanism. Furthermore, the in vivo data demonstrate that PhIP causes significant damage to the lung and liver after monitoring mice after 30 days of exposure to a larger amount of PhIP. These results indicate direct proof of COFs damage even at low exposure to HAAs and aldehydes.
