Published: March 2021

This study was aimed to apply Peleg Model to analyze rehydration of dried tekwan at several variations of water immersion temperature. The method used was descriptive and experimental of one factor treatment (Non Factorial), which was immersion temperature with four treatments level (30, 45, 70 and 90oC), each treatment was done triplicate. The parameter observed was moisture content at times of observation. The result showed that the Peleg Model coefficients (K1 and K2) were inversely affected by the temperature. The relationship was expressed into non-linear regression (polynomial) with R2 value of 0,973 and 0,988. It showed that the obtained Peleg model could be applied adequately for the rehydration of dried tekwan at some immersion temperature. The resulting model also met the statistical criteria with the largest SEE and MRE values 6.73% and 3.58%. The model could predict the dried tekwan rehydration best at the temperature of 30oC and 45oC with the smallest SEE and MRE values.

Improved Geosteering Information and Data Transfer using an Automated Computational Framework
Authors: D'Angelo John James , Ashok Pradeepkumar , van Oort Eric 
Published: March 2021

Abstract
Geosteering presently requires physical or virtual interaction between the geologist and the directional driller to arrive at steering decisions. This interaction often results in the loss of valuable information because all context and data may not be shared between them. A framework that is able to automatically integrate the data and information which the geologist and directional driller independently possess can result in improved decision making, and is the topic of this paper.
The geosteering framework described herein combines estimation and optimization methods to solve geosteering problems with minimal human intervention. Bayesian estimation procedures are used to approximate the distance from geological features, and a wellbore propagation model is used to estimate system responses of the drilling assembly. The geological estimates and directional drilling model are then jointly used to formulate geosteering decision-making as a stochastic optimization problem. Finally, this optimization problem can be solved to aid decision making. This is done without the need for humans to interact, which significantly reduces potential information loss. This procedure is illustrated for two synthetic case studies.
Machine-Learning-Assisted Segmentation of Focused Ion Beam-Scanning Electron Microscopy Images with Artifacts for Improved Void-Space Characterization of Tight Reservoir Rocks
Authors: Kazak Andrey , Simonov Kirill , Kulikov Victor 
Published: March 2021

SummaryThe modern focused ion beam-scanning electron microscopy (FIB-SEM) allows imaging of nanoporous tight reservoir-rock samples in 3D at a resolution up to 3 nm/voxel. Correct porosity determination from FIB-SEM images requires fast and robust segmentation. However, the quality and efficient segmentation of FIB-SEM images is still a complicated and challenging task. Typically, a trained operator spends days or weeks in subjective and semimanual labeling of a single FIB-SEM data set. The presence of FIB-SEM artifacts, such as porebacks, requires developing a new methodology for efficient image segmentation. We have developed a method for simplification of multimodal segmentation of FIB-SEM data sets using machine-learning (ML)-based techniques.We study a collection of rock samples formed according to the petrophysical interpretation of well logs from a complex tight gas reservoir rock of the Berezov Formation (West Siberia, Russia). The core samples were passed through a multiscale imaging workflow for pore-space-structure upscaling from nanometer to log scale. FIB-SEM imaging resolved the finest scale using a dual-beam analytical system. Image segmentation used an architecture derived from a convolutional neural network (CNN) in the DeepUNet (Ronneberger et al. 2015) configuration. We implemented the solution in the Pytorch® (Facebook, Inc., Menlo Park, California, USA) framework in a Linux environment. Computation exploited a high-performance computing system.The acquired data included three 3D FIB-SEM data sets with a physical size of approximately 20 × 15 × 25 µm with a voxel size of 5 nm. A professional geologist manually segmented (labeled) a fraction of slices. We split the labeled slices into training, validation, and test data. We then augmented the training data to increase its size. The developed CNN delivered promising results. The model performed automatic segmentation with the following average quality indicators according to test data: accuracy of 86.66%, precision of 54.93%, recall of 83.76%, and F1 score of 55.10%. We achieved a significant boost in segmentation speed of 14.5 megapixel (MP)/min. Compared with 0.18 to 1.45 MP/min for manual labeling, this yielded an efficiency increase of at least 10 times.The presented research work improves the quality of quantitative petrophysical characterization of complex reservoir rocks using digital rock imaging. The development allows the multiphase segmentation of 3D FIB-SEM data complicated with artifacts. It delivers correct and precise pore-space segmentation, resulting in little turn-around-time saving and increased porosity-data quality. Although image segmentation using CNNs is mainstream in the modern ML world, it is an emerging novel approach for reservoir-characterization tasks.

Abstract
Ethiopia including the study area are faced with deforestation, land degradation, soil erosion problems primarily caused by anthropogenic activities such as clearing vegetation for the purpose of agricultural use, fuel wood, Charcoal, construction and the reaction of conservation measures to restore deforested vegetation is too weak. The aim of the study was to investigate the effect of soil and water conservation (SWC) measures on plant species diversity by comparing between treated plot areas and non-treated plot areas. The data collection method was mainly drawn through plant measurements, inventory, GPS, household servey, key informant interview, focus group discussion, Office reports. To analyze the collected data, Shannon – wiener diversity index (H1) and Sorensen similarity coefficient indices (Is) calculation methods was employed. Based on the interview, direct observation, shannon’s diversity analysis and GPS results, the findings revealed that noticeable vegetation cover and plant species diversity have been observed in treated plot areas than non-treated plot areas in the last 10 years period.. This implies that well managed and protected homegardens and area exclosures have better plant species diversity than open grazing fields and communal lands. With these findings, it is rational to conclude that SWC measures have a positive effect on vegetation cover, Plant species diversity, richness and restoration. Thus, it is worth to recommend that conservation priority should be given to the more affected open grazing and communal lands.

Abstract
In this paper, two dimensional photonic crystal based Add Drop filter is designed for DWDM applications. The existing work concentrate in Coarse Wavelength Division Multiplexing (CWDM) and few filter design with DWDM with non-uniform channel spacing, and low quality factor. . The proposed Add Drop Filter (ADF) enhances the quality factor using Rounded Square Ring Resonator (RSRR) for ensuring efficient bandwidth in supporting WDM systems. The design consists of bus waveguide, drop waveguide and RSRR with inner quasi-square ring in the square lattice while dielectric constant of the Si rod is 11.68 which are hosted in the air. The line defect was created by removing 4 rods (Quasi ring) in the center of the inner square ring. The line defects in the cavity help to reduce the radiation field components surrounded by the resonator. The proposed design drops the unique wavelength 1636.2 nm from a spectrum. The performance parameters of ADF are investigated using 2D Finite Difference Time Domain (FDTD) algorithm. The proposed ADF drops the narrow bandwidth of 0.7 nm, high quality factor of 2337, dropping efficiency (ON State) of 100 %, which is highly sufficient to support WDM systems for future Photonic Integrated Circuits (PIC). Further, the impact of functional parameters such as transmission efficiency, quality factor, bandwidth are investigated by varying the structural parameters, namely, adjacent rod radius, scatterer rod radius, coupling rod radius, lattice constant, inner rod radius and rod radius. The size of the device is 412.76 µm2.

Abstract
Background Type 2 diabetes (T2D) is associated with an increased risk of cardiovascular (CV) disease. In patients with T2D and established CV disease, selective inhibitors of sodium–glucose cotransporter 2 (SGLT2) have been shown to decrease CV and all-cause mortality, and heart failure (HF) admissions. Utilising CV magnetic resonance imaging (CMR) and continuous glucose monitoring (CGM) by FreeStyle Libre Pro Sensor, we aim to explore the mechanisms of action which give Empagliflozin, an SGLT2 inhibitor, its beneficial CV effects and compare these to the effects of dipeptidyl peptidase-4 inhibitor Sitagliptin. Methods This is a single centre, open-label, cross-over trial conducted at the Leeds Teaching Hospitals NHS Trust. Participants are randomised for the order of treatment and receive three months therapy with Empagliflozin, and three months therapy with Sitagliptin sequentially. Twenty eight eligible T2D patients with established ischemic heart disease will be recruited. Patients undergo serial CMR scans on 3 visits, at week 0, week 12 and week 24 of the study.Discussion The primary outcome measure is the myocardial perfusion reserve in remote myocardium. The secondary outcome measures are myocardial fibrosis, ECV, aortic distensibility, LV/RV volume and function, and the relationship between glycemic markers and CV parameters.We hypothesize that Empaglifozin treatment is associated with improvements in myocardial blood flow and reductions in myocardial interstitial fibrosis, independent of CGM measured glycemic control in patients with T2D and established CV disease. Trial registration This study has full research ethics committee approval (REC: 18/YH/0190) and data collection is anticipated to finish in December 2021. This study was retrospectively registered at https://doi.org/10.1186/ISRCTN82391603 and monitored by the University of Leeds. The study results will be submitted for publication within 6 months of completion.

Published: March 2021

Abstract
Wetland methane emissions in the permafrost regions of the Qinghai-Tibet Plateau is more sensitive to climate warming and can result in a positive climate feedback. Natural gas hydrate, as a potential methane source, may play a pivotal role in wetland methane emission in the permafrost regions. However, it was lacking of evidence. To determine the role of gas hydrate release in wetland methane emission, the two-year field monitoring of methane emitted from a hydrate drilling well, in near-surface soil free gas and low-level air was conducted at a typical gas hydrate reservior in the Qilian Mountains permafrost. The carbon isotope fractionation between CO2 and CH4 (εC) associated with carbon isotopic composition of methane (δ13CCH4) is used as a good tracer to identify methane sources of thermogenic origin or of microbial origin. The monitoring results of the gas hydrate drilling well DK-8 indicated a notable release of the deep gas hydrates occurred in April- May and resulted in the increase of methane content in low-level air. The significance of gas hydrate release in the permafrost region on local wetland methane emission as well as low-level air methane was confirmed by the seasonal variation of methane source of near-surface soil fluxes and low-level air. The thermogenically derived methane were identified as the dominant methane source in autumn and winter compared with increasing contribution of microbially derived methane in summer. The carbon isotopic signatures of tracing methane sources can provide more reliable evidence for gas hydrate release and its effect on the wetland methane emission in the Qilian Mountains permafrost.

Published: March 2021

Abstract
Objective: The problems caused by diabetes mellitus (DM) related complications are the focus in clinical treatment. However, little is known about diabetic enteropathy (DE) and its the potential underlying mechanism. Methods: Intestinal cells (IEC) and Intestinal stem cells (IESC) obtained from BKS.Cg-Dock7m+/+Leprdb/JNju (DM) mice were used to detect Rspo3 by RT-qPCR, western blotting, Immunohistochemistry, and immunofluorescence. The role of Rspo3 in the abnormal differentiation of IECs of DM was clarified by knockout experiments. Through miRNA expression profiles, bioinformatic analysis, and RT-qPCR, we further analyzed differentiation related miRNA from IECs in DM mice. Results: The abnormal differentiation of small intestinal epithelial cells (IECs) was found in DM state. The expression of R-spondin 3 (Rspo3) was upregulated in IECs of DM state. And this phenomenon was associated with R-spondin 3 (Rspo3) overexpression. Additionally, Rspo3 is a major determinant of Lgr5+ stem cell identity upon DM state. Microarray analysis, Bioinformatics analysis and luciferase reporter assays revealed that microRNA (miR)-380-5p was directly targeted Rspo3. Moreover, miR-380-5p upregulation was observed to attenuate the abnormal differentiation of IECs through Rspo3 expression. Conclusion: Together, our results provide definitive evidence for the essential role of Rspo3 in differentiation of small intestinal epithelial cells (IECs) in DM state.

Abstract
Background

Several miRNAs are now known to have clear connections to the pathogenesis of asthma. The present study focused on the potential role of miR-3934 during asthma development.
Methods

The basophils was isolated from 50 asthmatic patients and 50 health controls. The expression level of miR-3934 was examined by RT-qPCR and the expression of receptor for advanced glycation end products (RAGE) was detected by western blot. In addition, the analysis of apoptotic basophils was performed by flow cytometry; the expression level of inflammatory cytokines was detected by ELISA kits; and several important proteins in TGF-β/Smad signaling were examined by western blot.
Results

miR-3934 was down-regulated in the basophils of asthmatic patients. The expression of the pro-inflammatory cytokines IL-6, IL-8 and IL-33 was enhanced in basophils from asthmatic patients, and this effect was partially reversed by transfection of miR-3934 mimics. Furthermore, receiver operating characteristics analysis showed that miR-3934 levels can be used to distinguish asthma patients from healthy individuals. miR-3934 partially inhibited advanced glycation end products-induced increases in basophil apoptosis by suppressing expression of RAGE.
Conclusion

Our results indicate that miR-3934 acts to mitigate the pathogenesis of asthma by targeting RAGE and suppressing TGF-β/Smad signaling.

Abstract
Background and objectives: Suicide is a topical issue in Lithuania and all around the world. It is the second most common cause of death among young people. There is a lack of research studies on the psychosocial aspects of adolescent suicide in Lithuania. This study aimed to evaluate demographics, life circumstances, and health conditions as factors related to suicide attempt in adolescents. Materials and Methods: A retrospective study was performed at the Children’s Hospital (Vilnius University Santara Clinics). Medical documentation of adolescents treated in this hospital after suicide attempts from January 2011 to April 2018 were analyzed. Results: There were 117 cases of hospitalization due to suicide attempts during this period, and 102 cases were included in the study. There were 83.8% female and 16.2% male patients with an average age of 15.02 ± 1.9 years (p = 0.405); 40.6% of patients lived in divorced families, 17.7% lived in orphanages, 4.2% lived in foster care, 36.4% suffered from parental alcoholism, and 17.2% experienced suicide in their close surroundings. They had comorbidities (girls 72.5%, boys 68.8%), mostly depression (31.3%), were suffering from bullying (54.1%) or violence (26.0%), and 85.4% showed signs of other types of self-harm (girls more often (p < 0.001)). Most of them chose to cut for suicide attempts (86.0% girls, 56.2% boys). In 52.8% of cases, the attempt was spontaneous and 34% relapsed. Thirty-four events occurred in March (18.9%) (p = 0.688). Conclusions: Our study revealed the possible circumstances related to adolescent suicide attempt. Female gender was more common overall and males were more likely to carry out more potentially lethal methods. Other common associated factors were a lack of prosperity in family life, experience of bullying, violence, comorbidities, and the early spring period. Signs of any self-harm could be an indicator of later suicide attempt.
