Published: November 2022

The study of the content of neutral lipids (NL) and higher fatty acids (HFA) in three species of the genus Allium from the flora of the Komi Republic: A. angulosum, A. schoenoprasum and A. strictum is carried out. The amount of neutral lipids in different parts of the studied plants averaged from 0.5 to 6.5% of the air-dry mass. Seeds of all kinds were distinguished by the greatest accumulation of NL (up to 10–13%). It is shown that the composition of the NL of the studied species consists mainly of fatty acid molecules with a chain length of C14 – C20 and an even number of carbon atoms. Their distribution by parts of the plant has common patterns for all three species. The main amount of saturated fatty acid in all parts of the plant is palmitic acid C16:0, the amount of which is 20.8–49.1% of the total acid content. Of unsaturated acids, linoleic acid (C18:2) dominates, the content of which lies in the range of 21.9–73.0%. Linolenic acid (C18:3) it accumulates in maximum amounts in the leaves, from 25.5 to 37.0%, while in other parts its content does not exceed 10%. The leaves are characterized by an organ-specific distribution of linoleic and linolenic acids, the quantitative ratio of which is close to 1 : 1. Linoleic acid is the main content in seed oil (from 69.3 to 73.0%), and the total amount of unsaturated acids exceeds 92%. The study of seasonal dynamics showed that the content of NL in the leaves and bulbs of A. angulosum and A. stricrum is maximal in the regrowth phase and minimal in the flowering phase. In luke A. schoenoprasum the largest amount of NL was found in the budding phase, in the fruiting phase it dropped to the minimum values.

Lonicera caerulea L. and its subspecies Lonicera caerulea subsp. edulis (Turcz. ex Freyn) Hulten and Lonicera caerulea subsp. altaica Pall. belong to the genus Lonicera L. family Caprifoliaceae Juss., they are valuable fruit plants that are used in medicine, food industry, agriculture. The value of these species lies in the early ripening of fruits and a high content of vitamin C and other biologically active compounds.
The aim of the study was the qualitative and quantitative determination of the main groups of biologically active substances – organic acids and tannins, in the fruits of three species of the genus Lonicera from the collection of the South Ural Botanical Garden-Institute and the selection of the most promising species. For analysis, honeysuckle fruits were collected in the full ripening phase and dried to an air-dry state. Phytochemical studies were carried out according to generally accepted methods.
As a result of the study, it was found that all the studied honeysuckle samples contain citric, malic, succinic, oxalic, ascorbic acids, and tartaric acid in Lonicera caerulea subsp. edulis. According to the quantitative content of ascorbic acid and the sum of organic acids, a species is distinguished in Lonicera caerulea subsp. edulis, whose fruits contain 174 and 1723 mg/100 g respectively, and in Lonicera caerulea subsp. altaica and Lonicera caerulea their content is below. The analysis of fruits for the content of tannins showed, that they are dominated by substances of condensed nature, which are based on catechism, and in a larger amount they accumulate in Lonicera caerulea – 426 mg/100 g in a smaller amount – in Lonicera caerulea subsp. edulis – 171 mg/100 g.
The obtained data allow us to recommend the studied species of the genus Lonicera as a promising source of raw materials for the creation of medicinal plant products based on them, enriched with vitamins and other valuable biologically active substances on their basis.

Abstract
Visual features play a key role in indoor positioning and navigation services as the main semantic information to help people understand the environment. However, insufficient semantic constraint information and mismatching localization without building map have hindered the ubiquitous application services. To address the problem, we propose a smartphone indoor scene features recognition localization method with building map semantic constraints. First, based on Geographic Information System and Building Information Modeling techniques, a geocoded entity library of building Map Location Anchor (MLA) is constructed, which is able to provide users with “immersive” meta-building-map and semantic anchor constraints for mobile phone positioning when map matching. Second, using the MYOLOv5s deep learning model improved on indoor location scenario, the nine types of ubiquitous anchor features in building scenes are recognized in real time by acquiring video frames from the smartphone camera. Lastly, the spatial locations of the ubiquitous indoor facilities obtained using smartphone video recognition are matched with the MLA P3P algorithm to achieve real-time positioning and navigation. The experimental results show that the MLA recognition accuracy of the improved MYOLOv5s is 97.2%, and the maximum localization error is within the range of 0.775 m and confined to the interval of 0.5 m after applying the Building Information Modeling based Positioning and Navigation road network step node constraint, which can effectively achieve high positioning accuracy in the building indoor scenarios with adequate MLA and road network constraint.

The effect of cigarette smoking on the serum levels of calcium and 25 hydroxy vitamin D in patients with postmenopausal osteoporosis
Authors: Wu Lifang , Du Qiang 
Published: November 2022

Abstract

Objectives
Deficiency of calcium and vitamin D is a common finding in postmenopausal osteoporosis (PMOP). However, the effect of cigarette smoking on the serum levels of calcium and 25-hydroxyvitamin D [25(OH)D] remains inconclusive.

Methods
The data of 432 inpatients with PMOP between January 2016 and October 2019 were collected from the hospital information system of the Second Hospital of Shanxi Medical University. The associations between smoking habits and serum calcium and 25(OH)D levels were analyzed by multiple linear regression. The intensity and duration of smoking were also conducted in the analysis to detect the dose-dependent effect of cigarette smoking.

Results
Significant differences were found between smokers and never smokers regarding serum calcium and 25(OH)D levels. The multiple linear regression model showed significant negative associations of the daily number of cigarette smoking and the smoking durations with the serum calcium and 25(OH)D levels. Moreover, the effect of smoking on the decreased levels of serum calcium and 25(OH)D showed a dose-dependent manner.

Conclusions
Cigarette smoking was negatively associated with the serum calcium and 25(OH)D levels in patients with PMOP. Early detection of serum calcium and 25(OH)D may contribute to predicting fracture risk, and smoking cessation intervention is necessary for patients with POMP.
Hydrothermal and cerium salt sealing of a 6061 aluminum alloy
Authors: Gong Lihua , Liu Tiannan , Guo Weimin 
Published: November 2022

Abstract
The influences of the environmentally friendly sealing processes of cerium salt sealing and hydrothermal sealing on the electrochemical behavior of the anodic oxide film of an aluminum alloy were examined by accelerated corrosion of dry-wet alternate immersion corrosion tests, combined with the morphologies observation, chemical composition tests, and electrochemical tests. A severe corrosion environment with high temperature, high humidity, and high salt spray was adopted. The results of electrochemical characteristics show that cerium salt sealing affected the inner barrier layer of the film instead of the outer porous film. The higher impedance of the inner barrier layer is related to the reaction between cerium ions and cathodic reaction products of hydroxyl ions. Hydrothermal sealing, although had some good influence on both the porous layer and the barrier layer of the oxide film, corrosion inhibition on the whole cannot do better than that of cerium salt sealing in the early days. However, as the corrosion time went on, the hydrothermal sealing sample showed better durability.

Published: November 2022

Abstract
It is known that the strain rate affects significantly the mechanical properties of the engineering materials. The aim of this study is to investigate the effect of the cross-head speed on the mechanical properties of acrylate and methacrylate-based oligomer/monomer materials of the specimens produced by Stereolithography (SLA) printer. The characteristic mechanical properties of materials, such as modulus of elasticity, Poisson’s ratio, and the ultimate strength depending on low strain rate levels were explored. The fractured surfaces of the tensile test specimens were examined by Scanning Electron Microscopy (SEM). Based on the experimental results, it is concluded the mechanical properties of the photosensitive resins are quite sensitive to the tensile test speeds.

A review on the chemistry of novel platinum chelates based on azo-azomethine ligands
Authors: Mandal Paritosh , Pratihar Jahar L. 
Published: November 2022

Abstract
Numerous platinum group metals (PGMs) complexes contain azo-azomethine-based ligands. Azo-azomethine ligands are N-donor ligands that have extended conjugated π-bonded systems and both azo (–N=N–) and aldimine (–C=N–) functions in their structure. Plenty of platinum (Pt) complexes with azo-imine ligands have been prepared and characterized. Various multidentate azo-imine ligands coordinated with different platinum metal substrates afforded structurally diverse platinum chelates. Nonetheless, many azo-imine-based platinum complexes demonstrated a wide range of biological activities, photo-switchable properties, and redox activities. The review encompasses a general overview of platinum complexes with versatile azo-azomethine ligands, their synthetic protocol, spectroscopic and structural features, chemical reactivity, and multipurpose applications in different areas.

Abstract
Three sesquiterpene lactones (1–3) were isolated from the aerial part of Tithonia diversifolia (Hemsl.) A. Gray grown in the Hoa Binh province in Viet Nam. The structures of these three sesquiterpene lactones were identified as tagitinin A (1), 1β-hydroxytirotundin 3-O-methyl ether (2), and tagitinin C (3) by analyzing spectroscopic data. For the first time, compound 2 was isolated from T. diversifolia growing in Viet Nam. Furthermore, contrary to existing literature, we determined that compound 1 was the major isolate. Compounds 1 and 3 significantly decreased numbers of acute myeloid leukemia OCI-AML3 cells by promoting apoptosis and causing cell cycle arrest at G0/G1 phase at concentrations as low as 2.5 μg/mL (compound 1) and 0.25 μg/mL (compound 3). Additionally, all three compounds showed cytotoxic activity against five human cancer cell lines (A549, T24, Huh-7, 8505, and SNU-1), with IC50 values ranging from 1.32 ± 0.14 to 46.34 ± 2.74 μM. Overall, our findings suggest that compounds 1 and 3 may be potential anti-cancer therapeutics and thus warrant further study.
A Model for the Propagation of Seizure Activity in Normal Brain Tissue
Authors: Depannemaecker Damien , Carlu Mallory , Bouté Jules , Destexhe Alain 
Published: November 2022

AbstractEpilepsies are characterized by paroxysmal electrophysiological events and seizures, which can propagate across the brain. One of the main unsolved questions in epilepsy is how epileptic activity can invade normal tissue and thus propagate across the brain. To investigate this question, we consider three computational models at the neural network scale to study the underlying dynamics of seizure propagation, understand which specific features play a role, and relate them to clinical or experimental observations. We consider both the internal connectivity structure between neurons and the input properties in our characterization. We show that a paroxysmal input is sometimes controlled by the network while in other instances, it can lead the network activity to itself produce paroxysmal activity, and thus will further propagate to efferent networks. We further show how the details of the network architecture are essential to determine this switch to a seizure-like regime. We investigated the nature of the instability involved and in particular found a central role for the inhibitory connectivity. We propose a probabilistic approach to the propagative/non-propagative scenarios, which may serve as a guide to control the seizure by using appropriate stimuli.
A Multi-View Fusion Neural Network for Answer Selection
Authors: Sha Lei , Zhang Xiaodong , Qian Feng , Chang Baobao , Sui Zhifang 
Published: November 2022

Community question answering aims at choosing the most appropriate answer for a given question, which is important in many NLP applications. Previous neural network-based methods consider several different aspects of information through calculating attentions. These different kinds of attentions are always simply summed up and can be seen as a ``single view", causing severe information loss. To overcome this problem, we propose a Multi-View Fusion Neural Network, where each attention component generates a ``view'' of the QA pair and a fusion RNN integrates the generated views to form a more holistic representation. In this fusion RNN method, a filter gate collects important information of input and directly adds it to the output, which borrows the idea of residual networks. Experimental results on the WikiQA and SemEval-2016 CQA datasets demonstrate that our proposed model outperforms the state-of-the-art methods.

Published: November 2022

The reproductive success of birds depends on many factors, including nest construction and placement. In the mountainous regions of southwestern Iran, broods of Eastern Rock Nuthatch Sitta tephronota were surveyed in 2016 and 2017. During the study, 11 broods in rocky cavities and 16 in abandoned Syrian woodpeckers’ Dendrocopos syriacus tree cavities were compared in terms of breeding performance (phenology, clutch size, hatching success, number of fledglings, breeding success). The Eastern Rock Nuthatch began egg-laying on March 24 and continued until April 15. The number of eggs in the clutch ranged from 3 and 7 (mean 5.6±1.19, median 6, N = 27). The two types of clutches compared usually contained 6 eggs, and the number of nestlings was statistically lower in tree cavities than in rocky nests. Hatching success was almost 30% higher in rocky nests than in tree cavities. In broods located in trees, 4 nestlings hatched most often (42%, N = 12), and in rock nests, 5 nestlings hatched (50%, N = 10). Rocky nests were also statistically greater (by over 40%) for breeding success. For all analysed broods and broods with success, roughly two extra fledglings left the rocky nests compared with tree cavities. 5 fledglings (50%, N = 10) most often left rocky nests, whereas, in general, 4 fledglings (50%, N = 10) left tree nests. Research results did not confirm that woodpecker cavities are safe nest sites for cavity dwellers.

Published: November 2022

The article is devoted to the study and analysis of the mechanism of undulating propulsion in the case of its application in underwater robots. It gives a brief review of studies related to developing a mathematical model of the movement of an underwater robot. Robot using two-symmetry undulating fin. This mathematical model imitates the movement of some fish species, such as batoid rays. The purpose of the study was to substantiate the possibility of creating a propulsion mechanism. In this mechanism the undulating movement of the fin is provided by individual elements controlled by servomotors. With appropriate control, these movements provide the propagation of the wave in the flexible fin of the robot. The advantage of this approach is a significant increase in the maneuverability of the device compared to existing traditional models. Also, the movement becomes almost silent. The experiments performed on a robot prototype. As a result, a relation is found between the parameters of the undulating movement and the linear speed and thrust of each fin. The parameters of undulating movement such frequency and amplitude are analyzed, to provide stable movement of the underwater robot. The experiments confirmed the possibility of implementing the proposed control method. They Showed the possibilities of controlling the direction of propulsion force by changing oscillating phase of each fin ray. Also, the possibilities of controlling the thrust of the fin by changing the amplitude and frequency of undulating movement of the fin.
