Nymphaea pubescens grows in Lebak swampland in its different levels of water depth. This aquatic plant has an absorption system that moves gases through the laminae and has a convective flow system through air canals in midrib and petiole. This study aims to determine the adaptive structure of air canal in the water lilies (Nymphaea pubescens) laminae and how its structure varies along with water-depth fluctuations. The research was conducted by observing plants in 4 (four) different zones of water depth: (1) water depth between 28-95 cm (zone I), (2) 28-99 cm (zone II), (3) 54-112 cm (zone III), and (4) 55-124 cm (zone IV).
Every lamina area, lamina thickness, and cross-sectional area (XS) of petiole, a number and area of air canals in midrib and petiole were collected for analysis. The results showed that the cross-sectional area of the laminae N. pubescens increased along with water depth, but the correlation with laminae thickness decreased. The midrib air canals are symmetrically divided and there was one main canal pair, an additional three pairs of canals, and a pair of smaller canals.
The cross-sectional area of the midrib and air canal increased along with water depth. The calculation of the area of four pairs of air canals is 75%. Air canals make up 34% of midrib cross-sectional area. The midrib air canals produced one pair of air canals, an additional two pairs of canals and a pair of smaller canals. The calculation of the area of three pairs of airways is 93%. Air canals make up 31% of the cross-sectional area of the petiole. The length of the petiole, the volume of the petiole, and the volume of the air canal increased along with water depth, but the cross-sectional area of the petiole and the air canal were not related by water depth.

Published: March 2023

The Tunpu (屯堡) village in Anshun city Guizhou province has unique cultural assets, particularly in the village’s spatial layout, its traditional building, and the spectacular Dixi (地戏) opera. In the context of the Chinese Rural Revitalization Strategy, a suitable combination of Cultural Heritage (CH) and the tourism industry to promote the rural revitalization of Tunpu Village is of practical significance. However, the Coronavirus disease (COVID-19) has had a severe impact on the rural revival of Tunpu Village. This article analyzes the current situation of rural revitalization in Tunpu villages from the perspectives of CH and the tourism industry through fieldwork of three Tunpu villages that have already developed tourism up to certain stages. We observed that the participation rate of villagers is not high; the villagers’ income through village tourism projects is generally low. While tourist attractions mainly consist of traditional architectural landscapes, buildings management and protection were an issue. CH plays an active role in the tourism industry, but the support provided to tourist facilities and entertainment projects could be further improved. The article concludes that the collaboration of the village government, villagers, and tourism company plays an essential role in integrating the tourism industry and CH. The right strategy is the guide, and the cooperation of the participants is the guarantee.

Abstract

Objective
To evaluate the color adjustment potentials of monoshade universal composites in different shades of class I cavities.

Methodology
About 132 restorations were performed using monoshade universal composites (Omnichroma, OMNI; Essentia Universal; EU; Charisma Diamond One, CDO), and one simplyshade composite (NeoSpectra-ST, NEO) as control. A transparent silicone mold was used to provide standardized restorations on prefabricated class I cavities of acrylic dentures in B1, A2, and C4 shades. The assessment of color adjustment was performed immediately after, at 24 h, and at 2 weeks, through the cross-polarized dental photographs. The quantitative assessments were performed using a software (Digital Color Meter, Macintosh AC). The collected L*, a*, and b* coordinates from the restorations and the adjacent denture surfaces were used to provide

Conclusion
Monoshade universal composites presented acceptable but perceptible color adjustment potentials in class I cavities without the shade selection procedure. Simplyshade composites following the shade selection might still be the best options regarding the level of color adjustment. Monoshade universal composites might provide better color adjustments in cavities with lighter shades.
Multi-kernel property in high-frequency price dynamics under Hawkes model
Authors: Lee Kyungsub 
Published: March 2023

Abstract
This study investigates and uses multi-kernel Hawkes models to describe a high-frequency mid-price process. Each kernel represents a different responsive speed of market participants. Using the conditional Hessian, we examine whether the numerical optimizer effectively finds the global maximum of the log-likelihood function under complicated modeling. Empirical studies that use stock prices in the US equity market show the existence of multi-kernels classified as ultra-high-frequency (UHF), very-high-frequency (VHF), and high-frequency (HF). We estimate the conditional expectations of arrival times and the degree of contribution to the high-frequency activities for each kernel.

AbstractDespite exhibiting tau phosphorylation similar to Alzheimer’s disease (AD), the human fetal brain is remarkably resilient to tau aggregation and toxicity. To identify potential mechanisms for this resilience, we used co-immunoprecipitation (co-IP) with mass spectrometry to characterize the tau interactome in human fetal, adult, and Alzheimer’s disease brains. We found significant differences between the tau interactome in fetal and AD brain tissue, with little difference between adult and AD, although these findings are limited by the low throughput and small sample size of these experiments. Differentially interacting proteins were enriched for 14-3-3 domains, and we found that the 14-3-3-β, η, and γ isoforms interacted with phosphorylated tau in Alzheimer’s disease but not the fetal brain. Since long isoform (4R) tau is only seen in the adult brain and this is one of the major differences between fetal and AD tau, we tested the ability of our strongest hit (14-3-3-β) to interact with 3R and 4R tau using co-immunoprecipitation, mass photometry, and nuclear magnetic resonance (NMR). We found that 14-3-3-β interacts preferentially with phosphorylated 4R tau, forming a complex consisting of two 14-3-3-β molecules to one tau. By NMR, we mapped 14-3-3 binding regions on tau that span the second microtubule binding repeat, which is unique to 4R tau. Our findings suggest that there are isoform-driven differences between the phospho-tau interactome in fetal and Alzheimer’s disease brain, including differences in interaction with the critical 14-3-3 family of protein chaperones, which may explain, in part, the resilience of fetal brain to tau toxicity.

AbstractWhile several computational methods have been developed to predict the functional relevance of phosphorylation sites, experimental analysis of the interdependency between protein phosphorylation and Protein–Protein Interactions (PPIs) remains challenging. Here, we describe an experimental strategy to establish interdependencies between protein phosphorylation and complex formation. This strategy is based on three main steps: (i) systematically charting the phosphorylation landscape of a target protein; (ii) assigning distinct proteoforms of the target protein to different protein complexes by native complex separation (AP‐BNPAGE) and protein correlation profiling; and (iii) analyzing proteoforms and complexes in cells lacking regulators of the target protein. We applied this strategy to YAP1, a transcriptional co‐activator for the control of organ size and tissue homeostasis that is highly phosphorylated and among the most connected proteins in human cells. We identified multiple YAP1 phosphosites associated with distinct complexes and inferred how both are controlled by Hippo pathway members. We detected a PTPN14/LATS1/YAP1 complex and suggest a model how PTPN14 inhibits YAP1 via augmenting WW domain‐dependent complex formation and phosphorylation by LATS1/2.

OBJECTIVES
The incidence, as well as the predictors of mortality, for children receiving home mechanical ventilation (HMV) using population-based data in Canada is a current knowledge gap. Our objectives were to describe HMV incidence and mortality rates, and associations of demographic and clinical variables on mortality.

METHODS
Using Ontario health and demographic administrative databases, we conducted a retrospective cohort study (April 1, 2003–March 31, 2017) of children aged 0 to 17 years receiving HMV via invasive mechanical ventilation and noninvasive ventilation. We identified children with complex chronic conditions. We used data from Census Canada to calculate incidence rates and Cox proportional hazards modeling to assess for predictors of mortality.

RESULTS
We identified 906 children with a mean (SD) crude incidence rate of 2.4 (0.6) per 100 000 for pediatric HMV approvals that increased by 37% over the 14-year study period. Compared with children who were invasively ventilated, we found mortality was associated with noninvasive ventilation (adjusted hazard ratio [aHR], 1.9; 95% confidence interval [CI], 1.3–2.8). Mortality was highest in children from families in the lowest income quintile (aHR, 2.5; 95% CI, 1.5–4.0), those with neurologic impairment complex chronic conditions (aHR, 2.9; 95% CI, 1.4–6.4), those aged 11 to 17 years at HMV initiation (aHR, 1.5; 95% CI, 1.1–2.0), and those with higher health care costs in the 1 year before HMV initiation (aHR, 1.5; 95% CI, 1.3–1.7).

CONCLUSIONS
The incidence of children receiving HMV increased substantially over the 14-year period. Demographic variables associated with increased mortality were identified, suggesting areas requiring greater attention for care providers.

The object of this study is the processes of emergence, perception, and redistribution of loads in the supporting structure of a 1CC size container with end walls made of sandwich panels.
To reduce the longitudinal load of the container under operational modes, the introduction of sandwich panels into its design is proposed. This solution is implemented on the example of its end walls as the most loaded component of the body in operation.
The thickness of the sandwich panel sheet was determined, provided that the strength in operation is ensured. Mathematical modeling of dynamic load of a container with end walls made of sandwich panels placed on a platform car during shunting co-impact was carried out. It was established that taking into account the proposed improvement makes it possible to reduce the dynamic loads that the container perceives by 10 % compared to the typical structure. The results were confirmed by computer simulation of the dynamic load of the container. The models formed within the framework of the study were verified according to the F-criterion.
The results of calculations for the strength of the container showed that the stresses in its structure are 15 % lower than those in the typical one.
A feature of the findings is that the proposed improvement of the container helps improve its strength in operation by reducing the loads acting on it.
The scope of practical use of the results is the engineering industry, namely, railroad transport. At the same time, the conditions for the practical application of the research results are the introduction of energy-absorbing material as a component of the sandwich panel.
This study will contribute to devising recommendations for designing modern structures of vehicles of a modular type and for improving the efficiency of the transport industry

Published: March 2023

The current work presents a study of the tribological properties of composite materials designed based on polyethylene terephthalate (PET), which has an important role in the structures of machines, represented by tribological couplings made of composite polymers. The paper examined the effect of two factors, namely recycled waste heating time (HT) and weight percentage (wt. %), on the improvement of the abrasive wear resistance of micro-filler-reinforced epoxy composites.
The current research aims to develop epoxy composites by improving abrasive wear resistance while ensuring low cost and weight. Improving wear resistance due to the use of epoxy composites to connect joints that operate under conditions without lubrication in various industrial fields will increase their operational life. The signal-to-noise ratio was analyzed to find out the effect of test parameters HT and wt. % on the wear rate of epoxy composites. Using MINITAB 19 software, regression equations were obtained for each variable to compare it with the Artificial Neural Network (ANN) results. Predictive models based on the regression equation and artificial neural network were developed to predict the wear rate of epoxy composites, and to determine which model is more efficient, their results were compared and the most appropriate model with the low error was determined. The results of the current research showed that the wear resistance of epoxy composites reinforced with RCCF improved by 41 % when increasing wt. % and HT, and also showed that the ANN model is more suitable than the regression model for predicting the wear rate of epoxy composites

An issue related to using wood and wood products for building structures is to ensure their stability and durability during operation within wide limits. Therefore, the object of this study was a change in the properties of the polymer shell of powder paint on wood during thermal modification.
It is proved that in the process of thermal modification of wood, its structure changes, and accordingly, during the polymerization of powder paint, degassing occurs, which affects the polymer shell. Namely, during the thermal polymerization of powder paint at a temperature of 180 °C for untreated wood, shallow bubbles and craters are characteristic of the formed polymer shell. Instead, a smooth surface is marked for a sample of thermally modified wood. Thermogravimetric analysis data show thermogravimetric curves characterized by the loss of mass of the sample of the original wood with increasing temperature due to the processes of dehydration, destruction of hemicellulose and lignin. This is dehydration, accompanied by the destruction of the pyranose cycle, and carbonization to form a carbon residue and a complex mixture of volatile products. Due to this, bubbles and craters are formed in the polymer shell of the coating. Based on the obtained results of adhesion of the polymer shell on wood, which is treated with a mixture of epoxy polyester system with functional additives and a polymerization temperature of 180 °C, the adhesion level is 2.1 MPa. Reducing the polymerization temperature of a mixture of the epoxy polyester system with functional additives to 130 °C increases adhesion by 1.75 times, and the nature of the destruction passes through the polymer shell. For thermally modified wood, the level of adhesion is within 2.1 MPa, and the destruction takes place through the wood. This is due to the increased fragility of the surface after thermal modification of wood

The study objects were the Republic of Kazakhstan selection apple sorts: “Baiterek”, “Sarkyt” and “Saya”, also pear sorts: “Syilyk”, “Zhazdyk” and “Nagima”. Study of the process of moisture evaporation within vacuum drying of the fruits has essential value in the nutritional value saving. Basically, the product evaporative capacity is characterized by the evaporation resistance coefficient ‒ µ. Also during moisture removal, thermodynamic state of moisture changes that is described by water activity indicator ‒ aw. Experimental determination of these parameters allows for the analyzing moisture evaporation during vacuum drying process. Studies have established the following evaporation resistance coefficients: µ=2.03±0.07 for apple sorts and µ=2.3±0.05 for pear sorts. Either water activity decreases from 1.0 to 0.62±0.01 for apple sorts and from 1.0 to 0.65±0.04 for pear sorts. Two drying periods are discovered. The first drying period: 5.45–6.10 h for apple sorts; and 6.12–6.25 h. for pear sorts. The second drying period duration: 4.15–3.50 h for apple sorts; and 4.35–4.48 h for pear sorts. The critical humidity value: 27.1±2.1 % for apple sorts; and 30.1±2.5 % for pear sorts. Comparative analysis of calculated and experimental data shows maximum deviations 22.5 % for apple sorts and 23 % for pear sorts. The proposed equation for the calculating a moisture evaporation rate, considering the product properties and the hygroscopic parameters of air, can be used in practice to study the moisture evaporation dynamics from the product surface. The study results allow for the selecting an optimal mode for vacuum drying of apples and pears sorts in order to safe nutritional value and to produce biologically active additives for the food industry

The problem that is solved in the research is to increase the efficiency of decision making in management tasks while ensuring the given reliability, regardless of the hierarchical nature of the object. The object of the research is decision making support system. The subject of the research is the decision making process in management tasks using an improved wolf flock algorithm. The hypothesis of the research is to increase the efficiency of decision making with a given assessment reliability. In the course of the research, an improved optimization method based on an improved wolf flock algorithm was proposed. In the course of the conducted research, the general provisions of the theory of artificial intelligence were used to solve the problem of analyzing the objects state and subsequent parametric management in intelligent decision making support systems.
The essence of the improvement lies in the use of the following procedures, which improve basic procedures of the wolf flock algorithm, namely search and chase:
– taking into account the type of uncertainty of the initial data while constructing the wolf flock path metric;
– searching for a solution in several directions using individuals from the wolf flock;
– initial presentation of individuals from the wolf flock;
– an improved procedure for adapting a flock of wolves;
– taking into account the available computing resources while choosing the number of leaders in a flock of wolves.
An example of the use of the proposed method is presented on the example of assessing the state of the operational situation of a group of troops (forces). The specified example showed an increase in the efficiency of data processing at the level of 23–30 % due to the use of additional improved procedures
