Published: July 2023

Background: In view of the need for stronger accountability in agricultural research in recent years, present study was undertaken to assess the multidimensional impact of HUW 234, a pioneer wheat variety of Eastern Uttar Pradesh since 1986. The present work was carried out with the objective to study the adoption pattern of HUW 234 and estimate its impact on inputs’ demand and crop productivity. Methods: The primary data was collected from 160 farmers with the help of pre-tested questionnaire for the crop season 2016-17 from Azamgarh and Bhadohi district. The impact of HUW 234 on inputs’ demand and crop productivity was estimated by using translog profit function approach and Cobb-Douglas production function approach. Result: The estimated demand function equations imply that the variety is resource saving viz. water, fertilizer and labour saving. The net yield disadvantage of HUW 234 over other wheat varieties evaluated at sample means was around 11.52 per cent. The likeliness of farmer-consumer towards its taste can create new opportunities to increase profitability through premium prices. The results indicate the need for focused breeding efforts in old genotype as per the preferences of the farmers.

EFFICIENCY SUBSTANTIATION FOR A SYNTHETICAL METHOD OF CONSTRUCTING A MULTIVARIATE POLYNOMIAL REGRESSION GIVEN BY A REDUNDANT REPRESENTATION
Authors: Pavlov Alexander , Holovchenko Maxim , Drozd Valeriia 
Published: July 2023

In recent years, the authors in their publications have developed two different approaches to the construction of a multivariate polynomial (in particular, linear) regressions given by a redundant representation. The first approach allowed us to reduce estimation of coefficients for nonlinear terms of a multivariate polynomial regression to construction of a sequence of univariate polynomial regressions and solution of corresponding nondegenerate systems of linear equations. The second approach was implemented using an example of a multivariate linear regression given by a redundant representation and led to the creation of a method the authors called a modified group method of data handling (GMDH), as it is a modification of the well-known heuristic self-organization method of GMDH (the author of GMDH is an Academician of the National Academy of Sciences of Ukraine O. G. Ivakhnenko). The modification takes into account that giving a multivariate linear regression by redundant representation allows for construction of a set of partial representations, one of which has the structure of the desired regression, to use not a multilevel selection algorithm, but an efficient algorithm for splitting the coefficients of the multivariate linear regression into two classes. As in the classic GMDH, the solution is found using a test sequence of data. This method is easily extended to the case of a multivariate polynomial regression since the unknown coefficients appear in the multivariate polynomial regression in a linear way. Each of the two approaches has its advantages and disadvantages. The obvious next step is to combine both approaches into one. This has led to the creation of a synthetic method that implements the advantages of both approaches, partially compensating for their disadvantages. This paper presents the aggregated algorithmic structure of the synthetic method, the theoretical properties of partial cases and, as a result, the justification of its overall efficiency.

Authors: Richard Amélie B. , Lelandais Manon , Hirsch Fabrice , Jacquin-Courtois Sophie , Reilly Karen T. 
Published: July 2023

Abstract
Introduction: Mild Neurocognitive Disorders (mNCD) are characterized by a subtle decline in cognitive performance. Discourse analysis is a research method that investigates the verbal production of patients and has been used to screen for subtle cognitive impairment. Studies using discourse analysis are, however, rarely replicated. One reason for this is likely to be the lack of consistency across studies regarding the selection and definition of relevant linguistic features. The goal of this review is to identify reliable linguistic markers for the detection of subtle cognitive impairment in connected speech, and generate hypotheses associating these markers with underlying cognitive functions in a given discourse context.
Methods and analysis: Following the PRISMA guidelines, we will conduct a systematic review including five databases: PubMed, ScienceDirect, Embase, Web of Science, Google Scholar. We will include articles targeting a population of patients with subtle cognitive impairment, such as Mild Cognitive Impairment. Eligible articles will include at least one connected speech task and an analysis of linguistic features in this task. The data will be classified according to study population, connected speech task, analysed linguistic features, and methods used to compare cases and controls.

A Comparative Evaluation of Root Fracture Resistance of Three Techniques of Retrieval of Separated Endodontic Instruments from Curved Root Canals
(An In Vitro Study)
Authors: Ahmed Mariam 
Published: July 2023

Abstract
The separation of instruments before completion of root canal preparation especially in infected teeth was found to be associated with a high probability of failure of endodontic treatment. Retrieval of these separated instruments can aid in completion of endodontic treatment successfully. To our knowledge there are no studies on the effect of using different retrieval methods on root fracture resistance, retrieval time and success. Thus, the aim of this study is to assess and evaluate the efficiency of three different retrieval methods: ultrasonics, LeoPen loop system and XP-endo shaper in resistance to root fracture of extracted human lower molars with moderately curved roots after retrieval, success of retrieval method and retrieval time of separated instruments.
A 2700-yr record of Cascadia megathrust and crustal/slab earthquakes from Upper and Lower Squaw Lakes, Oregon
Authors: Morey Ann E. , Goldfinger Chris 
Published: July 2023

Abstract

We infer a ~ 2,700-year history of Cascadia megathrust and other earthquakes from two small mountain lakes located 100 km inland of the coast near the California/Oregon border. We use the characteristics of disturbance deposits in the historic portion of the sediment cores from the lower lake to identify a deposit from the 1700 CE Cascadia earthquake (deposit J). This deposit is composed of light-coloured silt (indicating it is enriched in watershed-sourced sediment), without visible mica grains (which would indicate a lake bedrock source), organic grading of the deposit tail, and a basal contact with evidence of rapid loading. Seven deposits downcore have some of the characteristics of deposit J. An age-depth model suggests that the five deposits most similar to deposit J (including deposit J) are temporal correlatives to the largest margin-wide marine turbidite event deposits from Goldfinger et al., 2012, (T1, T2, T3, T4, T5 and T6), whereas the two deposits with some of the characteristics are potential correlatives of smaller turbidites T5a and T5b. Other thinner deposits are temporal correlatives of T2a and T3a and other smaller deposits of uncertain origin. Lake core physical property data can be correlated to those from other regional lake records and offshore cores. These results suggest that small Cascadia lakes with sufficient sedimentation rates (~ 1–2 cm/decade) with mixed clastic and organic sedimentation may be good recorders of earthquakes, that subduction earthquake deposits are different from those from other types of earthquake deposits and deposits from other types of disturbances, such as floods.
Effects of Soft and Hard Fillers on Electromechanical Properties and Performance of Polydimethylsiloxane Elastomer for Actuator Applications
Authors: Prabhakar Om Prakash , Sahu Raj Kumar 
Published: July 2023

Abstract
Desired ratio of high relative permittivity and low elastic modulus limits the application of silicon rubbers in various engineering fields as flexible electromechanical actuators. The relative permittivity can be improved by incorporating varieties of high-k particles and polymer reagents as plasticizers and crosslinkers into elastomer matrix. The present work investigates the effect of polyethylene glycol flakes (PEG as plasticizer) and titanium boride (TB) particles (high-k particle) as soft and hard fillers respectively, on electromechanical (EM) properties of polydimethylsiloxane (PDMS) elastomer composite for soft actuators. Elastomer composites filled with various concentrations of fillers are created and labeled accordingly to distinguish impact of fillers on EM properties. Uniform dispersion for fillers is confirmed by FESEM, EDX, FTIR, and UV-Vis. Elastic modulus and relative permittivity are significantly influenced by filler contents for both fillers. Elastic modulus for lower concentrations (2 and 5 wt.%) of soft fillers (PEG) increases while 8 wt.% leads to as comparable to the base material (PDMS). Soft fillers (PEG) aid in maintaining low elastic modulus, whereas hard fillers (TB) increase electrical breakdown strength as well as dielectric loss with almost identical changes in relative permittivity for both composites. The maximum actuation strain of 30.8 % and 26.2% is attained for an in-house fabricated linear actuator with 8 wt.% of PEG and TB particles, respectively. Methodology and results may be helpful in selection of fillers to improve the dielectric behavior of silicon elastomers depending on the acceptable range of their adverse effect on other properties.

Abstract
In year 2020, a large-scale outbreak of pneumonia caused by new coronavirus has affected the development of many industries and enterprises in China. Under the strong leadership of the Chinese government, the development of the epidemic situation in China has been well controlled. The development of various industries also began to show a good situation, many large-scale sports competitions also need to be restored. In order to ensure the normal development of large-scale sports events, we need to consider the development of epidemic situation to determine the time of sports events. Based on the study of FPGA theory, this paper designs a specific scheme of programming and system debugging, which includes a variety of program operations. In order to better predict the situation of the epidemic situation, this paper also uses the basic knowledge of machine learning to establish a relevant model to evaluate the situation of large-scale sports events under the development of the epidemic situation, and provide feasible suggestions for the recovery of large-scale sports events under the epidemic situation.

Published: July 2023

Abstract
Model’s generalization and feature selection are always two challenging problems for gas leakage detection. This paper presents a method for gas leakage detection based on Hybrid-Feature-Selection-Stacking ensemble learning (HFS-Stacking), which fuses the Hybrid Feature Selection and Stacking ensemble learning. Firstly, a hybrid feature selection algorithm (HFS), which combines SFS-SVM, SFS-KNN, RFE-RF, RFE-XGB, and MIC algorithms, is proposed to select the optimal feature subset from multiple commonly used acoustic signal features; Then, SVM, KNN, random forest and XGBoost are designed as base learners in the stacking integration framework, which increase the generalization ability of the model. XGBoost is used as the meta-learner to output the classification results. The proposed gas leakage detection method gets the optimal subset of features and speeds of the subsequent model. Meanwhile, the constructed model can effectively improve the indicator of ,, and, and has a good generalization ability. The experimental results show that the HFS-Stacking algorithm using fewer features can effectively improve the training speed, accuracy, F1-score, AUC value and recall rate, and also has better robustness.
Progesterone-induced Progesterone Receptor Membrane Component 1 Rise-to- Decline Changes are Essential for Decidualization
Authors: Liu Hailun , Franken André , Bielfeld Alexandra P. , Fehm Tanja , Niederacher Dieter , Cheng Zhongping , Neubauer Hans , Stamm Nadia 
Published: July 2023

Abstract
Background
Decidualization of endometrial cells is the prerequisite for embryo implantation and subsequent placenta formation and is induced by rising progesterone levels following ovulation. One of the hormone receptors contributing to endometrial homeostasis is Progesterone Receptor Membrane Component 1 (PGRMC1), a non-classical membrane-bound progesterone receptor with yet unclear function. In this study, we aimed to investigate how PGRMC1 contributes to human decidualization.
Methods
To gain insight into PGRMC1-implication in infertility-related diseases, we analyzed its expression profile in RNA-sequencing datasets of endometrial biopsies. To further explore the function of PGRMC1 in human decidualization, we implemented an inducible decidualization system, which is achieved by culturing two human endometrial stromal cell lines in decidualization-inducing medium containing medroxyprogesterone acetate and 8-Br-cAMP. In our system, we measured PGRMC1 expression during hormone induction as well as decidualization status upon PGRMC1 knockdown at different time points. We further conferred proximity ligation assay to identify PGRMC1 interaction partners.
Results
PGRMC1 expression was altered in patients with infertility-related diseases and impaired decidualization, being significantly downregulated in most datasets. In in vitro experiments, we observed that PGRMC1 expression follows a rise-to-decline pattern, in which its expression level initially increased during the first 6 days after induction (PGRMC1 increasing phase) and decreased in the following days (PGRMC1 decreasing phase). Knockdown of PGRMC1 expression before the induction led to a failed decidualization, while its knockdown after induction did not inhibit decidualization, suggesting that the progestin-induced ‘PGRMC1 increasing phase’ is essential for normal decidualization. Furthermore, we found that the interactions of PHB1 and PHB2 with PGRMC1 were induced upon progestin treatment. Knocking down either PHB individually or both slowed down the decidualization process compared to the control, suggesting that PGRMC1 cooperates with PHBs to regulate the decidualization.
Conclusions
According to our findings, PGRMC1 expression followed a progestin-induced rise-to-decline expression pattern during human endometrial decidualization process; and the correct execution of this expression program was crucial for successful decidualization. Thereby, the results of our in vitro model explained how PGRMC1 dysregulation in patients with impaired decidualization contributes to the manifestation of their disease.

Published: July 2023

Abstract
Herein, novel surface structure LaFeO3/nitrogen-deficient g-C3N4 nanocomposites (LaFeO3/g-C3N4-H) have been successfully synthesized by a two-step process. In the first step, as a precursor, acetic acid-treated melamine was thermally condensed to create nitrogen-deficient graphitic carbon nitride (g-C3N4-H). After that, LaFeO3 was incorporarated on the g-C3N4-H nanosheets. The as-prepared nano structured materials were characterized by XRD, FT-IR, N2 adsorption–desorption experiments, FESEM and TEM, demonstrating the formation of interfacial interaction and heterogeneous structure in LaFeO3/g-C3N4-H nanocomposites. Additionally, UV-vis diffuse reflectance spectra (DRS) and photoluminescence spectra (PL) have been used to assess the optical properties of the nanohybrids. The results show that the LaFeO3/g-C3N4-H nanocomposite was successfully produced, with a reliable interfacial interface, and produced good heterojunction relationship between g-C3N4-H and LaFeO3 which may significantly boost the photocatalytic activity as compared to prinstine g-C3N4 and LaFeO3. Phenol degradation under visible light irradiation was used to test the photocatalytic activity of LaFeO3/g-C3N4-H, and the results showed that 10%-LaFeO3/g-C3N4-H had significant photocatalytic activity and remarkable adsorption efficiency, with an overall removal rate of phenol up to 88% after 180 minutes of visible light irradiation. This study may present a novel method for developing highly efficient artificial photocatalytic systems.
Nonlinear vibrations and wear predictions of slender cylinders with loose support subjected to axial flows

Published: July 2023

Abstract
Flow-induced vibration of fuel rods subjected to axial flows frequently appears in nuclear engineering, which has been a significant scientific problem still unsolved. This paper simplifies the fuel rod as a slender cylinder with loose support in axial flows, and explores nonlinear dynamics of the slender cylinder through theoretical modeling. The dynamical model is constructed with consideration of impact and friction forces attributed by the loose support. The results show that the flutter critical flow velocity and wear rate are dependent on clearance size and position of the loose support. The flow velocity range of buckling becomes narrower while the range for flutter becomes wider with the increase of clearance size. The flow velocity range for buckled behavior is widened, the flutter flow speed range is reduced as the clearance position is varied from upward end to downward end of the cylinder. It is indicated that there are optimal values for clearance size and position of the loose support where the flutter critical flow velocity is much higher and the wear rate is lowest. The present study can provide a theoretical basis for predicting flow-induced vibrations and designing the loose support for fuel rods in the nuclear engineering.
