Published: December 2021

Abstract
Agitation pipe is the important part of the electroplated diamond wire saw in the suspension sanding process. The structure type and the sandblasting configuration in agitation pipe play a role on the flow uniformity. Fluid flow in the different structure forms of agitating pipe was studied and the influence of sandblasting angle and the diameter was also contrasted. Results found that the central water type of agitation pipe has the better performance, generating the flow field distribution in the middle part with high velocity and small velocity on both sides. The order of sandblasting in performance was 30°, 45° and 60°. The better flow uniformity occurred in the configuration of sandblasting with the diameter 7.5 mm, 7 mm and 7.5 mm.

Published: December 2021

Abstract
Q235 steel /Al2O3 ceramics were brazed with Ag-CuO filler metal at 1050°C and held for 15min in air. When brazing Q235 steel and Al2O3 ceramics directly, it was found that serious oxidation occurred on the steel side during the brazing process. Although the joining was realized, a loose oxide film was formed on the surface of the base steel, which affected the mechanical properties of joints. When Q235 steel with aluminized surface was adopted to braze with Al2O3 ceramics, a Al2O3 layer formed on the surface of Q235 steel successfully avoided the oxidation of Q235 steel, and a compact and defection-free joint was obtained. The typical organization of joint was Al2O3/ CuAl2O4/ CuO/ Ag/ CuO/ CuAl2O4 /Al2O3/ FeAl/ FeAl2/ Fe.

Published: December 2021

Abstract
Measuring the content of dissolved gas components in transformer insulating oil by gas chromatography is an important means to judge the internal potential faults of oil filled electrical equipment in the process of operation supervision. The necessary work skills of power grid operators include the ability to detect the content of dissolved gas in transformer oil and judge the operation state of transformer. This paper introduces a preparation method and equipment of transformer standard oil. It can quickly prepare standard oils with various gas component contents. The standard oil quantity value is accurate, the data stability period is greater than 90 days, and the uncertainty is less than 5%. The equipment can be used for training and evaluation of transformer oil gas chromatographic analysis practitioners and calibration of transformer oil on-line gas chromatograph.
Ergotropy from quantum and classical correlations
Authors: Touil Akram , Çakmak Barış , Deffner Sebastian 
Published: December 2021

Abstract
It is an established fact that quantum coherences have thermodynamic value. The natural question arises, whether other genuine quantum properties such as entanglement can also be exploited to extract thermodynamic work. In the present analysis, we show that the ergotropy can be expressed as a function of the quantum mutual information, which demonstrates the contributions to the extractable work from classical and quantum correlations. More specifically, we analyze bipartite quantum systems with locally thermal states, such that the only contribution to the ergotropy originates in the correlations. Our findings are illustrated for a two-qubit system collectively coupled to a thermal bath.
An alternative index to NINO3.4 for predicting monthly rainfall anomaly in East Java
Authors: Haq B E A , Ryan M , Kurniawan A , Rafi A M 
Published: December 2021

Abstract
ENSO and NINO3.4 index are known to have some relation with Indonesian monthly rainfall anomaly. There is a gap between scientific studies on one hand and forecasting operational problems on the other hand since previous studies are not giving enough attention to the N+1,2,3 concept. The concept is about giving three next month rainfall anomaly prediction rather than connecting ENSO index with three-monthly rainfall anomaly. Here we propose an alternative index for ENSO. The median of categorical gridded rainfall anomaly of East Java is used as a general representation. Plots of correlation between the median and anomaly sea surface temperature from ReynSmithOIv2 are used to determine locus candidate to be compared with NINO3.4. The Near Maritime Continent (NMC) index is selected and proven to have a significant average difference in correlation between based on bootstrap technique. Verification of prediction used in this study is simulation-based and only uses binary hit-miss final result. Prediction is generated by simple linear regression with three lag times (2,3, and 4). Verification based on three categories shows that NMC’s hits are higher than NINO.34 in lag-2 and lag-3. In lag-2, NMC’s verification is 57.5% compared to only 38.7% for NINO3.4. However, NINO3.4 is a still better predictor in lag-4. Radar charts of monthly verifications are also developed.

Published: December 2021

Abstract
In line with the objectives of the Impact-Based Forecast, hydrological predictions are used to support water resources management, mitigation of natural disasters, and climate variability impacts. The Artificial Neural Network algorithm was applied to build the prediction model for the Saguling Reservoir monthly inflow by utilizing observation data; the monthly rainfall (P) and inflow (Q) as the predictors in different lag time; t (recent), t-1 (previous month), and t-11 (11 months ago). The predictors are simulated in three variations of hidden layer numbers (2, 6, and 10). The best model under the normal period is model nine with RMSE 31.23 and R 0.88. This model is also the best model under La Nina's condition with RMSE 30.01 and R 0.83. For the El Nino period. We found that model five is the best model with the highest accuracy at the level of generalization in both the training process and predict extreme conditions at the validation stage. Overall, this model has a good performance and high potential usage from a practical point of view and costs but needs further simulation to make it more reliable and robust in any climate conditions.

Abstract
Acceptability is an important factor in the success of additional feeding programs in the form of cookies in malnourished toddlers. The purpose of this study was to find out the acceptability of cookies that are substituted with mocaf flour, and varied with red bean flour, and herbal chicken gizzard. This experimental study was conducted using a completely randomized design using 3 factors and 3 treatments (C1, C2 and C3), namely each treatment used the same amount of mocaf flour, namely 120 g, red bean flour each 110 g, 100 g, 90 g and herbal chicken gizzard 20 g, 30 g and 40 g. Acceptance test was conducted on 30 toddlers aged 2-5 years in the Medan Tuntungan Health Center Work Area. The data were analyzed using the Krusskal-Wallis test and continued with the Mann-Whitney test. Based on the results of data analysis, it shows that organoleptic assessment based on flavour, color, taste, texture and form of treatment C1 is classified as favorable, while treatment C2 and C3 is classified as less favorable. The results of the Krusskal Wallis test proved that there were differences between the three cookie treatments (p< 0.05), and the Mann-Whitney test results showed that the C1-treated cookies were significantly different from the C2 and C3 treatments (p<0.05). In conclusion, cookies with mocaf flour substitution (120g) which were varied with more red bean flour (110g) and less gizzard (20g) had the best acceptability, so that it can be used as an additional food for the improvement of nutrition of toddlers with less nutrition.

Published: December 2021

Abstract
Multicomponent surface modification of carbon steels is of high interest in mechanical engineering due to its beneficial impact on machine components’ and structures’ surface properties. The present research was devoted to simulating the process of aluminides and borides formation on the surface of low-carbon steel during electron beam alloying and predict the phase composition of the obtained coatings. Computational thermodynamics and approximate calculation method were used to solve the problem mentioned above. Calculations were done in the temperature range between 200 and 2000 K at 10−3 Pa. It was discovered that the calculated and experimental data of the coating’s phase composition differs significantly. The only confirmed phase that was predicted by the calculations was sodium fluoride (NaF). It was established that NaF presence in the treatment paste was redundant for the electron beam alloying because of its low reactivity in a vacuum. XRD analysis revealed the following phases in the coating: Fe2B, Fe3C, and AlFe3.
Modifying of the dielectric properties of adsorbed water in the force field of a solid surface
Authors: Simakov I G , Gulgenov Ch Zh , Bazarova S B 
Published: December 2021

Abstract
The results of thermodynamic and acoustoelectric studies of changes in the dielectric properties of adsorbed water under the influence of a solid surface force field are presented. It is noted that the dielectric properties of adsorbed water depend not only on the characteristic size of the system, but also on the interaction energy with the solid surface. Near the hydrophilic solid surface, the density of adsorbed water is increased and the mobility of molecules is reduced. The opposite effect occurs for hydrophobic surfaces. The frequency dependences of the dielectric properties of adsorbed water, as in the case of water in the solid and liquid phase, can be characterized using Debye relaxation theory. It is shown that a significant increase in the orientational dielectric relaxation time in adsorbed water can be explained by taking into account the energy of interfacial boundaries.

Published: December 2021

Abstract

Background
Postsurgical scar management significantly affects patient satisfaction. However, reliable skin support options are limited.

Objectives
The present study aimed to determine the efficacy and safety of using tissue adhesive zippers in postsurgical scar prevention among patients undergoing surgical excision of the face. The primary outcome was a reduction in scar width, which was evaluated 1, 3, 6, and 12 months postoperatively. Scar width at Month 12 was considered the final outcome.

Methods
This was a prospective, randomized, controlled, rater-blinded trial. Sixty-four patients were randomly assigned to 2 groups (the zip group, defined as those using a tissue adhesive zipper for 3 months after surgery, and the control group). Outcomes were evaluated 1, 3, 6, and 12 months postoperatively based on scar width and Patient Observer Scar Assessment Scale score. Skin irritation was monitored during the first 3 months after surgery. The incidence of hypertrophic scar formation was recorded at a 12-month follow-up.

Results
Scar width differed significantly between the zip (mean [standard deviation], 1.68 [0.45] mm) and control groups (2.15 [0.64] mm). The scars spread rapidly in the first month after surgery but slowed down and stabilized after 6 months. The Patient Observer Scar Assessment Scale scores of the zip group were significantly lower than those of the control group. Neither group experienced significant complications.

Conclusions
Prolonged use of tissue adhesive zippers immediately after surgery reduced scar width and improved scar appearance without obvious side effects.

sc-REnF: An entropy guided robust feature selection for single-cell RNA-seq data
Authors: Lall Snehalika , Ghosh Abhik , Ray Sumanta , Bandyopadhyay Sanghamitra 
Published: December 2021

AbstractAnnotation of cells in single-cell clustering requires a homogeneous grouping of cell populations. Since single-cell data are susceptible to technical noise, the quality of genes selected prior to clustering is of crucial importance in the preliminary steps of downstream analysis. Therefore, interest in robust gene selection has gained considerable attention in recent years. We introduce sc-REnF [robust entropy based feature (gene) selection method], aiming to leverage the advantages of $R{\prime}{e}nyi$ and $Tsallis$ entropies in gene selection for single cell clustering. Experiments demonstrate that with tuned parameter ($q$), $R{\prime}{e}nyi$ and $Tsallis$ entropies select genes that improved the clustering results significantly, over the other competing methods. sc-REnF can capture relevancy and redundancy among the features of noisy data extremely well due to its robust objective function. Moreover, the selected features/genes can able to determine the unknown cells with a high accuracy. Finally, sc-REnF yields good clustering performance in small sample, large feature scRNA-seq data.

Back translation for molecule generation

Published: December 2021

AbstractMotivationMolecule generation, which is to generate new molecules, is an important problem in bioinformatics. Typical tasks include generating molecules with given properties, molecular property improvement (i.e. improving specific properties of an input molecule), retrosynthesis (i.e. predicting the molecules that can be used to synthesize a target molecule), etc. Recently, deep-learning-based methods received more attention for molecule generation. The labeled data of bioinformatics is usually costly to obtain, but there are millions of unlabeled molecules. Inspired by the success of sequence generation in natural language processing with unlabeled data, we would like to explore an effective way of using unlabeled molecules for molecule generation.ResultsWe propose a new method, back translation for molecule generation, which is a simple yet effective semisupervised method. Let X be the source domain, which is the collection of properties, the molecules to be optimized, etc. Let Y be the target domain which is the collection of molecules. In particular, given a main task which is about to learn a mapping from the source domain X to the target domain Y, we first train a reversed model g for the Y to X mapping. After that, we use g to back translate the unlabeled data in Y to X and obtain more synthetic data. Finally, we combine the synthetic data with the labeled data and train a model for the main task. We conduct experiments on molecular property improvement and retrosynthesis, and we achieve state-of-the-art results on four molecule generation tasks and one retrosynthesis benchmark, USPTO-50k.Availability and implementationOur code and data are available at https://github.com/fyabc/BT4MolGen.Supplementary informationSupplementary data are available at Bioinformatics online.

Published: December 2021

AbstractThe mechanisms by which sex is determined, and how a sexual phenotype is stably maintained during adulthood, have been the focus of vigorous scientific inquiry. Resources common to the biomedical field (automated staining and imaging platforms) were leveraged to provide the first immunofluorescent data for a reptile species with temperature induced sex reversal. Two four-plex immunofluorescent panels were explored across three sex classes (sex reversed ZZf females, normal ZWf females, and normal ZZm males). One panel was stained for chromatin remodeling genes JARID2 and KDM6B, and methylation marks H3K27me3, and H3K4me3 (Jumonji Panel). The other CaRe panel stained for environmental response genes CIRBP and RelA, and H3K27me3 and H3K4me3. Our study characterized tissue specific expression and cellular localization patterns of these proteins and histone marks, providing new insights to the molecular characteristics of adult gonads in a dragon lizard Pogona vitticeps. The confirmation that mammalian antibodies cross react in P. vitticeps paves the way for experiments that can take advantage of this new immunohistochemical resource to gain a new understanding of the role of these proteins during embryonic development, and most importantly for P. vitticeps, the molecular underpinnings of sex reversal.

Abstract

Aim
Recurrence indicates a failed repair. Which biomechanical factors have to be considered to reduce failure rates? How can surgeons enhance the interface between mesh and tissue?

Material and Methods
The strength of the mesh-tissue interface was evaluated by cyclic loading. A self-made bench test was used to apply dynamic intermittent strain (DIS) to model preparations in order to evaluate the tissue quality and the material properties of hernia meshes and fixation devices.
The influences and the properties were condensed in coefficients representing their relative strengths. The strain of the individual human abdominal wall were determined with computerized tomography at rest and during Valsalva’s maneuver.

Results
The strain observed in porcine, bovine and human tissue was in the same range. Tissue samples exhibited both brittle and ductile failure patterns. Both the load duration and the peak load increased destruction. Stress concentration elevated failure rates. Regional areas of distorsions increase stress concentrations. Hernia repair has to counteract individual strain levels. Measures to improve hernia repair include closure of the defect, use of higher DIS class meshes, increased mesh overlap and additional fixation. In the clinical routine, all measures must be adapted to the individual tissue quality.

Conclusions
Using the conception of GRIP as the gained resistance towards pressure related impacts, a durable hernia repair can be designed from coefficients determined with a bench test or with computerized tomography of the human abdominal wall. Pain levels and hernia recurrence rates can be reduced in incisional hernia repair when biomechanical principles are considered.

Abstract

Aim
A diaphragmatic hernia (DH) is a protrusion of abdominal contents into the thoracic cavity as a result of a defect within diaphragm. It is most common as a congenital phenomenon; however, there have also been cases where it can be acquired. DH can be life-threatening, resulting in incarceration and strangulation.

Material and Methods
From June 2009 to April 2021, ten cases of strangulated diaphragmatic hernia were admitted to our Emergency Surgery Department of General Surgery with respiratory and abdominal symptoms. Patients' characteristics, operation details, and postoperative complications were retrospectively analyzed.

Results
There were 5 (50%) men and 5 (50%) women with a mean age of 66 years (range, 20–85 years). . Emergency surgery was performed by laparoscopic in 4(40%) patients and open in 6(60%) patients. Two patients had a history of penetrating trauma to the left thoracoabdominal region. Segmental bowel resection was performed in 3 patients and total gastrectomy in 1 patient. Reconstruction was not performed in the patient who underwent total gastrectomy due to ischemia and perforation. In the postoperative period, wound infection was observed in 2 patients. Anastomotic leakage was observed in 1 patient and treated with end enterostomy. Empyema was observed in one patient after discharge, the empyema was evacuated and thoracoscopic decortication was performed .The patient who underwent total gastrectomy died due to septic shock and comorbid diseases.

Conclusions
Strangulated diaphragmatic hernia is a life-threatening condition and requires emergency surgery. Laparoscopic techniques can also be used in treatment.
