Research on Parameter Identification of Bouc-Wen Model of Magnetorheological Damper using Least Square Method
Authors: Jorayev Bagtyyar , Jing Li
Published: June 2023

The Bouc Wen magnetorheological damper model has eight unknown parameters, and the mathematical expression of the model includes the evolution quantity, absolute value term, and exponential term of differential equation, which complicates parameter identification. Researchers in related fields have made numerous attempts to solve the problem that the model's parameter identification method is complex and difficult to implement. A method combining nonlinear least square method is proposed to identify the parameters of the Bouc-Wen model of magnetorheological damper based on the damping characteristics test. Analyze the relationship between the identification parameters and the current and use the curve fitting toolbox to fit the functional relationship. At the same time, use the Simulink toolbox to create a Bouc-Wen simulation model of a magnetorheological damper and select sinusoidal signals with varying current, amplitude, and frequency for simulation and comparison. The Bouc-Wen model is validated using additional amplitude and frequency test data, and the results show a high degree of fit between the test and simulation results. This method can effectively identify the dynamic model's parameters.
Población ocupada y nivel de ingreso en las actividades terciarias en México en 2005, 2020 y 2021
Authors: Ovando Aldana Wendy , Rivera Rojo Celso Rodrigo , Reyes Hernández Marlen Rocío
Published: June 2023

Objetivo: caracterizar a la población ocupada por nivel de ingreso en el sector terciario en México en 2005, 2020 y 2021.
Diseño Metodológico: con datos de la Encuesta Nacional de Ocupación y Empleo se segmentó el mercado de trabajo y se estimaron tres modelos de regresión logística ordinal generalizados. Se tomó como variable dependiente el nivel de ingreso y como independientes: nivel de instrucción, sexo, edad, población ocupada por condición de ocupación, empleo formal e informal, tamaño de empresa y por subsectores.
Resultados: a medida que la edad y nivel de instrucción del trabajador se incrementan, las probabilidades de percibir un mayor ingreso aumentan. Además, las mujeres tienen menos probabilidades de alcanzar el ingreso superior; sin embargo, la diferencia se acorta en 2020 y 2021. Al mismo tiempo, el empleo formal ofrece 22% menos de probabilidad de obtener de 0 a 1 salarios mínimos en comparación con quienes se ubican en el sector informal. La probabilidad de obtener el máximo salario en empresa grande en comparación con la microempresa es apenas de 1%. Las ramas con mayor probabilidad de obtener el mejor ingreso fueron: Servicios sociales, y Gobierno y Organismos Internacionales.
Limitaciones de la investigación: se estimaron los modelos con base en la Encuesta Nacional de Ocupación y Empleo sobre la clasificación de la población ocupada por nivel de ingreso nominal.
Hallazgos: el estudio da cuenta de la segmentación del mercado de trabajo en las actividades terciarias, aunque se detectó, por medio de la reducción de las probabilidades, una tendencia en la disminución en el número de segmentos.

AR Mobile Application for Human Anatomy
Authors: J Chandana
Published: June 2023

Abstract: Anatomy is the main topic of human biology. The study of interior body organs, from cells to organ systems, is known as human anatomy. Studying the 2D model of the internal structure is difficult and tiresome. The purpose of this study is to develop a 3D Augmented Reality anatomy of human learning system. When learning anatomy through textbooks, puppets, or 2D models, it might be difficult to understand the internal structure. One solution that has been developed is an Android app that uses augmented reality. An interactive menu in the program allows you to scan an image and see a 3D version of a model in actual space. This study uses Augmented Reality technology to create a human body learning system. It is hoped that by using this approach, students will be able to visualize the human body's parts in 3D with ease. Students can learn more quickly with the use of AR technology.

Definitions and Methods for Analysis of Multiple Cause of Death: A Scoping Review
Authors: Lopez-Barrios Michel , Peters Paul
Published: June 2023

Objective: This review aims to identify and categorise demographic methods used in modelling multiple causes of death. The assumption that each death is caused by exactly one disease is debatable, as other possible diseases or causes may be associated with the main cause. Hence, the multiple causes of death approach is essential for understanding mortality. Therefore, through this study, we will carry out a Scoping Review of the existing literature on the topic of MCOD. Inclusion criteria: This review considers literature pertaining to methods for the analysis and utilization of multiple cause of death data. Papers that discuss the methods used as well as the strengths and limitations of multiple cause of death approach will be considered for this study. Methods: Preliminary searches were conducted in July 2022 and focussed on concepts of multiple cause of death mortality and multiple causes of death. Searches were conducted in PubMed, Web of Science, and Scopus and was conducted in English, French, Spanish and Portuguese. There were no time constraints on the studies to be included in this review. Articles were initially screened by title and abstract and then reviewed by full text by three independent reviewers. Two reviewers extracted the data from the eligible articles. Results: A total of 769 papers were reviewed at the abstract and title level. Of these, 124 were screened for full-text eligibility. A total of 53 articles were included in the final analysis. Among the articles included, 31 were articles from the United States, 14 were from Europe and 8 were from other countries. The papers were categorized as methodological (33) papers, data assessment papers (19), papers discussing socioeconomic differences in mortality (13) and mixed method papers (11). Conclusions: There are many different types of methodologies and procedures used to analyse multiple cause of death statistics. All papers included in this study used descriptive methods (mostly frequency tables and cross-tabulations) to analyze multiple cause of death data, and almost half of them use visualizations to model the results. One of the most common limitations cited among the articles is the comparability of the statistics. Accurate data and analysis of vital statistics require resources, and many countries do not have the to report high-quality statistics. This could explain why most of the papers selected for this study focused on data from developed countries.
Generalized Belief Propagation Algorithms for Decoding of Surface Codes
Authors: Old Josias , Rispler Manuel
Published: June 2023

Belief propagation (BP) is well-known as a low complexity decoding algorithm with a strong performance for important classes of quantum error correcting codes, e.g. notably for the quantum low-density parity check (LDPC) code class of random expander codes. However, it is also well-known that the performance of BP breaks down when facing topological codes such as the surface code, where naive BP fails entirely to reach a below-threshold regime, i.e. the regime where error correction becomes useful. Previous works have shown, that this can be remedied by resorting to post-processing decoders outside the framework of BP. In this work, we present a generalized belief propagation method with an outer re-initialization loop that successfully decodes surface codes, i.e. opposed to naive BP it recovers the sub-threshold regime known from decoders tailored to the surface code and from statistical-mechanical mappings. We report a threshold of 17% under independent bit-and phase-flip data noise (to be compared to the ideal threshold of 20.6%) and a threshold value of 14% under depolarizing data noise (compared to the ideal threshold of 18.9%), which are on par with thresholds achieved by non-BP post-processing methods.
Comparison of The Molecular Docking Properties of Three Potentially Active Agents
Authors: GÖRGÜLÜ Güvenç , DEDE Bülent
Published: June 2023

Antineoplastic agents are generally the drugs used to recess or prevent tumor growth which is promoted in many cases by certain factors like vascular endothelial growth factor-2 (VEGFR-2) and cyclooxygenase-2 (COX-2). These two factors seem important in angiogenesis and lymphangiogenesis in fetal, normal and neoplastic tissue. Prevention of VEGF family of proteins and cyclooxygenase-2 enzyme is a good strategy to inhibit the growth of tumor tissue eventually may give rise to recession.

In this study, three potentially active and an active ligand were tested for their binding properties to two target molecules mentioned above by molecular docking study. This research is aimed to compare three different molecules according to their binding affinities, binding energies and the nature of bonds formed between the ligand and the target molecules. Showing the 3D structures will localize the fitted ligands on proteins and the possible hydrogen bonds formed were defined. Among the three proposed ligands, Ligand 1 showed the closest results to the commercial product lenalidomide®. All three ligands showed similar ∆G values and fitness scores with lenalidomide® which is an indicator of good fit, proximity and orientation with the target molecule.

Esenin’s Poem “Us”: Materials for Historical and Literary Commentary
Authors:   A.M. Gorky Institute of World Literature of the Russian Academy of Sciences, Skorokhodov Maxim V.
Published: June 2023

The article examines Esenin’s poem “Us” in the context of the poet’s works of 1914– 1917, first of all relating to the national history (“The Song of Yevpaty Kolovrat” and “Martha the Mayoress”). Special attention is paid to the historical sources of the “Us” poem in view of the wide range of Esenin’s readings in the mid-1910s and his classes in 1913–1915 at the History and Philology Department of the A.L. Shanyavsky Moscow State University. Esenin was able to familiarize himself with popular textbooks, songs of the Razin cycle as well as with historical works which pay considerable attention to Stepan T. Razin. At the same time Vasily R. Us was a rare and minor character in works devoted to Razin. One of the first addressed to the image of Us was Kamensky in his novel “Stenka Razin,” published in 1916. But if in Kamensky’s Us is an associate of Razin, in Esenin’s work he is an independent character, and the second central character is Us’ mother.
Poem by A.A. Akhmatova “Requiem” in the Dialogue of Cultures: Problems of Translation into Ossetian
Authors:   V.I. Abaev North Ossetian Institute for Humanitarian and Social Studies — the Filial of the Vladikavkaz Science Centre of the Russian Academy of Sciences, Dzaparova Elizaveta B.
Published: June 2023

The article provides a comparative analysis of the poem by A.A. Akhmatova (1889–1966) “Requiem” in the original and in the translation of the Ossetian poet A.M. Kozachi (1937–2021) to identify similarities and differences in lexico-semantic means, figurative system and symbolism. The purpose of the study is to trace the representation of the semantic space of the original in poetic translation. The author shows the main types of translation strategies in the transfer of idiostyle features, gives an assessment from the position of reflecting the emotional message of the original in translation as a whole. The search for invariant correspondences in the target language showed the translator’s desire for more emotional identity with the original and partly for stylistic one. With the help of functional equivalents A.M. Kozachi managed to reflect in the translated text the personal experiences of the lyrical female character, to convey the confessional pathos of the poem. The absence of equivalents in the target language to convey some poetic images forced the translator to resort to associative substitution. The folklore, Orthodox symbolism found in the text is sometimes translated by non-literal lexical means. Since this or that symbol could not always evoke similar associations in the recipient, the translator resorted to semantic adaptation.
The Joke in Aristophanes’ Assemblywomen (v. 21–23)
Authors:   А.M. Gorky Institute of World Literature of the Russian Academy of Sciences, Buzurnyuk Ekaterina N.
Published: June 2023

The article deals with the history of interpretation of the joke in v. 21–23 of Aristophanes’ Assemblywomen. There is no consensus among researchers about the meaning of the passage under consideration, what order of verses is preferable, and what role these verses play in the opening scene of the comedy. The textual and contextual analysis allows the author to interpret the obscure passage so that the proposed interpretation suits the poetics of Aristophanes’ comedies best. The author of the article argues against the change in the manuscripts’ order of the verses. The passage in question should be understood as follows: Aristophanes quotes a certain Phyromachus, who in public space made a speech mistake and instead of ἑτέρας ἕδρας ʽother places’ said ἑταίρας ἕδρας, which approximately means ‘hetairas’ seats.’ Since the context implies that the female characters ought to ʽtake their places,’ the quotation of Phyromachus’ mistake turns out to be suitable. In addition, the reduction of the paratragic pathos of the opening scene of the comedy with the help of a joke based on physiological humor is characteristic for the poetic toolkit of Aristophanes and allows him to gain the favor of viewers of different cultural levels.
Spanish Mystic of the 16th Century and the “Spiritual Canticle” of Saint John of the Cross
Authors:   The Official Language School Barcelona Drassanes (EOIBD), Ignatieva (Oganissian) Maria Yu.
Published: June 2023

The article analyzes the poetics of the “Spiritual Canticle” of St. John of the Cross as a single two-part work, consisting of a poetic text and its prosaic commentary. The “Spiritual Canticle” is one of the masterpieces of Spanish mystical literature of the 16th century. The author of the article describes this literary context, showing the reasons for its emergence and flourishing, the main directions and features, and then proceeds to analyze the poetics of the texts under consideration. The relationship between poetry and prose in the literary legacy of St. John of the Cross is one of the traditional themes of juanística. The article proposes to consider both the one and the other as a manifestation of both the mystical experience and the poetic genius of St. John, without placing the commentary in an auxiliar position in relation to the verses. By interpreting his own poetic text, John creates a new parallel text on the same topic, but in a different genre. Each component has its own internal plot.These two plots, called “lyrical” and “theological,” enter into complex relationships. Thus, “mountains,” “forests,” “extraordinary islands” and other images change their meaning both in verses and in commentary, revealing a general but whimsical transformation of an earthly topos into a transcendental one. Transformation takes place through various types of intersection of created and uncreated beginnings: in man, in nature and in God. Poems from lyrics become sacred text, commentary from didactic becomes exegetical.
he Monstrous Feminine: Politics of Gender and Fear in the Adaptation of “Tejeemola” in Kothanodi
Authors: Guptha Sruthi B , V Sandhya
Published: June 2023

Contemporary folklore studies transcend genre, language, culture, time, and space in addressing the pertinent questions of representation, appropriation, and counter-cultures. This paper attempts to address gender politics in the formulation of horror in the visual adaptation of the famous Assamese folktale “Tejeemola” (1911) in Bhaskar Hazarika’s film Kothanodi (The River of Fables, 2015). The interval of almost a century makes Kothanodi undisputedly informed by contemporary postmodern discourses on femininity, sexuality, and socio-cultural changes in the conventions of gender. The retelling utilizes the trope of motherhood in the construction of the monstrous feminine to evoke fear. The paper looks critically at a) the cultural implications of fear in the visual adaptation by interrogating the monstrous feminine against the cultural glorification and romanticization of the maternal feminine, and b) how fear is used as a culturally rooted gendered tool in the language of cinema, drawing from Scruton’s Sociophobics: The Anthropology of Fear. The objective of this critical analysis is to recognize the fragile and fluid borders which shape our idea of fear and disassociate it from the intricate web of cultural conditioning.
Perception through the Personified: A Study of Children’s Folklore from Bihar, India
Authors: Tosha Mallika , Dwivedi Rajiv Ranjan
Published: June 2023

The research explores the children-related literature of Bihar, an eastern state of India, in order to find their impact on the perception of the listeners. There is a range of research on folklore from India; however, there has yet to be much research on children-related folklore in Bihar. Considering this research gap, the present research intends to study the effect of children’s folklore on shaping their psyche. Through a qualitative analysis, the research attempts to find answers to questions such as: how do the verbal elements of the Bihari folklore affect children’s way of thinking; do these folk genres always boost their wisdom or at times question their sense of perceiving morality; does folklore play any role in spreading awareness. We recorded rare folklore and folk beliefs and interviewed the natives of three districts as representatives of the ancient Magadh, Mithila, and Anga regions of Bihar. We concluded that folklore and folk beliefs could be important tools in spreading wisdom, humanitarian perspectives, and environmental consciousness among children. Therefore, the folk genre contributes to raising awareness of cultural norms within society.
Trauma and Fairy Tales in Lonely Castle in the Mirror by Mizuki Tsujimura
Authors: Prasol Yevheniia
Published: June 2023

This article deals with the metaphoric representation of childhood traumatic experiences through references to European fairy tales in the novel Lonely Castle in the Mirror by Mizuki Tsujimura, “an innovative and tender blend of social commentary and magical realism” as defined by Riyoko Shibe. The paper traces the different ways the author incorporates European fairy tales and introduces the fantastic to describe the traumatic experiences of the children who went through severe bullying at school. The article attempts to demonstrate that these references serve both as symbolic representations of these experiences and as an escape from them, as they provide a metaphorical means to deal with the psychological distress.
The clutch size, incubation rhythm of Reeves’s Pheasant (Syrmaticus reevesii) and their responses to ambient temperature and precipitation

Published: June 2023

Clutch size and incubation rhythm are critical components of avian life
history. Incubating birds must balance the trade-offs between their
energy requirements and the thermal needs of the developing embryos.
Reeves’s Pheasant (Syrmaticus reevesii) is a uniparental bird endemic to
China that lives in mountain forests, and female Reeves’s Pheasants may
adjust their incubation behavior to cope with cold environments and
energy stress. Using satellite tracking, we tracked 21 wild female
Reeves’s Pheasants in northern Hubei Province, China from 2020 to 2022,
and explored the birds’ clutch size, incubation rhythm and their
responses to ambient temperature and precipitation. The average clutch
size of Reeves’s Pheasant was 7.72 ± 1.51, showing strong seasonal
declines, and was markedly affected by the average temperature during
the spawning period. During the incubation period, the females took 0.74
± 0.46 recesses per day with an average recess duration of 99.23 ± 72.93
mins and an average nest attendance of 93.11 ± 5.06%. There was a peak
of nest departures at around 13:00, and the recess duration was
significantly negatively correlated with both daily mean temperature and
daily precipitation. Our findings demonstrated that female Reeves’s
Pheasants adjusted their behavior in response to the changing ambient
temperature and precipitation, and the unimodal pattern of recess timing
may not be driven primarily by the physiological needs of incubating
females, but by the thermal needs of their developing embryos.
Light-dark cycles influence soil bacterial composition in situ
Authors: Fickling Nicole , Abbott Catherine , Brame Joel , Cando-Dumancela Christian , Liddicoat Craig , Robinson Jake , Breed Martin
Published: June 2023

Soil bacterial taxa have important functional roles in ecosystems (e.g.,
nutrient cycling, soil formation, plant health). Many factors influence
their assembly and regulation, with land cover type (e.g., remnant
vegetation, agriculture, urban parks) and plant-soil feedbacks being two
well studied factors. However, changes in soil bacterial communities in
situ over light-dark cycles have received little attention, despite
plants and some bacteria having endogenous circadian rhythms that could
influence soil bacterial communities. We sampled surface soils in situ
across 24-hour light-dark cycles (at 00:00, 06:00, 12:00, 18:00) at two
land cover types (remnant vegetation vs. cleared, grassy areas) and
applied 16S rRNA amplicon sequencing to investigate changes in bacterial
communities. We show that land cover type strongly affected soil
bacterial diversity, with soils under native vegetation expressing
15.41-16.42% lower alpha diversity but 4.92-10.67% greater
heterogeneity than soils under cleared vegetation. In addition, we
report time-dependent and site-specific changes in bacterial network
complexity and between 598-922 ASVs showing significant changes in
relative abundance across times. Native site node degree (bacterial
interactions) at phylum level was 16.0% higher in the early morning
hours compared to the afternoon/evening. Our results demonstrate for the
first time that light-dark cycles have subtle yet important effects on
the composition of soil bacterial communities in situ and that land
cover influences these dynamics. We provide a new view of soil microbial
ecology and suggest that future studies should consider the time of day
when sampling soil bacteria.
On the Detection of Upper Mantle Discontinuities with Radon-Transformed Ps Receiver Functions (CRISP-RF)
Authors: Olugboji Tolulope , Zhang Ziqi , Carr Steve , Ekmekci Canberk , Cetin Mujdat
Published: June 2023

Seismic interrogation of the upper mantle from the base of the crust to
the top of the mantle transition zone has revealed discontinuities that
are variable in space, depth, lateral extent, amplitude, and lack a
unified explanation for their origin. Improved constraints on the
detectability and properties of mantle discontinuities can be obtained
with P-to-S receiver function (Ps-RF) where energy scatters from P to S
as seismic waves propagate across discontinuities of interest. However,
due to the interference of crustal multiples, uppermost mantle
discontinuities are more commonly imaged with lower resolution S-to-P
receiver function (Sp-RF). In this study, a new method called CRISP-RF
(Clean Receiver-function Imaging using SParse Radon Filters) is
proposed, which incorporates ideas from compressive sensing and
model-based image reconstruction. The central idea involves applying a
sparse Radon transform to effectively decompose the Ps-RF into its
underlying wavefield contributions, i.e., direct conversions, multiples,
and noise, based on the phase moveout and coherence. A masking filter is
then designed and applied to create a multiple-free and denoised Ps-RF.
We demonstrate, using synthetic experiment, that our implementation of
the Radon transform using a sparsity-promoting regularization
outperforms the conventional least-squares methods and can effectively
isolate direct Ps conversions. We further apply the CRISP-RF workflow on
real data, including single station data on cratons,
common-conversion-point (CCP) stack at continental margins, and seismic
data from ocean islands. The application of CRISP-RF to global datasets
will advance our understanding of the enigmatic origins of the upper
mantle discontinuities like the ubiquitous Mid-Lithospheric
Discontinuity (MLD) and the elusive X-discontinuity.

East Asia (China, Japan, Koreas and Mongolia) has been the world’s
economic engine over at least the past two decades, exhibiting a rapid
increase in fossil fuel emissions of greenhouse gases (GHGs) and has
expressed the recent ambition to achieve climate neutrality by
mid-century. However, the GHG balance of its terrestrial ecosystems
remains poorly constrained. Here, we present a synthesis of the three
most important long-lived greenhouse gases (CO2, CH4 and N2O) budgets
over East Asia during the decades of 2000s and 2010s, following a dual
constraint bottom-up and top-down approach. We estimate that terrestrial
ecosystems in East Asia is close to neutrality of GHGs, with a magnitude
of between 196.9 ± 527.0 Tg CO2eq yr-1 (the top-down approach) and -20.8
± 205.5 Tg CO2eq yr-1 (the bottom-up approach) during 2000-2019. This
net GHG emission includes a large land CO2 sink (-1251.3 ± 456.9 Tg CO2
yr-1 based on the top-down approach and -1356.1 ± 155.6 Tg CO2 yr-1
based on the bottom-up approach), which is being fully offset by
biogenic CH4 and N2O emissions, predominantly coming from the
agricultural sector. Emerging data sources and modelling capacities have
helped achieve agreement between the top-down and bottom-up approaches
to within 20% for all three GHGs, but sizeable uncertainties remain in
several flux terms. For example, the reported CO2 flux from land use and
land cover change varies from a net source of more than 300 Tg CO2 yr-1
to a net sink of ~-700 Tg CO2 yr-1.

Published: June 2023

Climate change is one of the most serious challenges facing mankind.
Sphagnum moss plays an important role in the carbon sink of peatland.
Understanding the potential distribution of Sphagnum moss under climate
change scenarios is critical for the conservation and rational
exploitation of it. In this study, we divided the Hengduan Mountains
(HDM) into east (EHDM) and west (WHDM) parts to see the difference
between the whole and the parts, and understand the effects of integrity
and connectivity of the landscape on species distribution. Since no
enough occurrence data in EHDM, we applied the occurrence data in WHDM.
Then, MaxEnt model was employed to predict the potential distribution of
Sphagnum moss and computed the migratory paths of the distribution
center points. We found precipitation in the coldest quarter, daily
range of average temperature, isothermality and slope were the main
factors affecting the suitable habitat for Sphagnum moss in HDM and
WHDM. In HDM, the current potential suitable habitat is 2.6×104 km2, and
will increase over 8 times and tend to shift northeastward and higher
elevations in the future. In WHDM, the suitable area is 1.06×104 km2,
but will decline exceeds 70% under most future climate scenarios, and
tend to shift southward and lower elevations. Landscape integrity and
connectivity have a great impact on the distribution of HDM Sphagnum
moss species. Overall, our findings provide a reference for the
conservation and management of Sphagnum moss.
LUN-BiSeNetV2: A lightweight unstructured network based on BiSeNetV2 for road scene segmentation
Authors: Zhang Yachao , Zhang Min
Published: June 2023

With the continuous introduction of automatic driving technology, the research of road scene segmentation algorithm in machine vision has become very important. In traditional methods, most researchers use machine learning methods to segment thresholds. However, the introduction of deep learning in recent years makes convolutional neural networks widely used in this field. Aiming at the problem that the traditional threshold segmentation method is difficult to effectively extract the threshold value of road image in multiple scenes and the serious problem of over-segmentation caused by deep neural network training data directly, this paper proposes a road scene segmentation method based on a lightweight unstructured network based on BiSeNetV2. The network contains backbone segmentation network and BiSeNetV2 network. The Mobilenetv2 network is used in the backbone network to replace the Xception feature extraction network in the decoder. In addition, grouping convolution is used to replace common convolution in Mobilenetv2 network. And it selects the batch specification layer to reduce the number of parameters, without affecting the accuracy and improving the efficiency of segmentation. At the same time, due to the relatively fixed distribution position of unstructured roads in the image, attention mechanism is introduced to process advanced semantic features, so as to improve the sensitivity and accuracy of the network. The BiSeNetV2 network enhances the dominant relationship between channel features by adding a compression excitation module based on channel attention mechanism after the detail branch, so as to perceive key areas and highlight local features. The lightweight feature pyramid attention mechanism is used to optimize semantic branches, improve the feature integration between contexts, extract high-level road semantic information more efficiently and retain spatial location information to the maximum extent. Finally, local semantic features and high-level semantic features are fused to improve the effect of unstructured road detection. The experiment is trained on the open data set. The results show that compared with other state-of-theart networks, the accuracy and real-time performance of proposed LUN-BiSeNetV2 in this paper are good, and the false segmentation and edge clarity are better. Compared with the classical algorithm, the average intersection is improved by 2.2% compared with mIoU, the average pixel accuracy is improved by 7.6%, and the frame rate is improved by 24.5%.

To solve the problems of large number of similar Chinese characters, difficult feature extraction and inaccurate recognition, we propose a novel multilevel stacked SqueezeNet model for handwritten Chinese character recognition. First, we design a deep convolutional neural network model for feature grouping extraction and fusion. The multilevel stacked feature group extraction module is used to extract the deep abstract feature information of the image and carry out the fusion between the different feature information modules. Secondly, we use the designed down-sampling and channel amplification modules to reduce the feature dimension while preserving the important information of the image. The feature information is refined and condensed to solve the overlapping and redundant problem of feature information. Thirdly, inter-layer feature fusion algorithm and Softmax classification function constrained by L2 norm are used. We further compress the parameter clipping to avoid the loss of too much accuracy due to the clipping of important parameters. The dynamic network surgery algorithm is used to ensure that the important parameters of the error deletion are reassembled. Experimental results on public data show that the designed recognition model in this paper can effectively improve the recognition rate of handwritten Chinese characters.
Deep adversarial neural network model based on information fusion for music sentiment analysis
Authors: Chen Wenwen
Published: June 2023

Natural language processing (NLP) is a computer-based technology used to process natural language information in written and spoken form that is unique to human society. In the process of mining massive text information, a variety of technologies and research directions in the field of NLP have gradually emerged. And sentiment analysis is an important research direction, which has important research value and practical application value for enterprises and social life. Sentiment analysis is basically a single mining of semantic or grammatical information without establishing the correlation between semantic information and grammatical information. In addition, previous models simply embed the relative distance or grammatical distance of words into the model, ignoring the joint influence of relative distance and grammatical distance on the aspect words. In this paper, we propose a new model that combines deep adversarial neural network model based on information fusion for music sentiment analysis. Firstly, the information of music text sequence is captured by the bidirectional short and long time memory network. Then the sequence information is updated according to the tree structure of dependency syntactic tree. Then, the relative distance and syntactic distance position information are embedded into the music text sequence. Thirdly, the adversarial training is used to expand the alignment boundary of the field distribution and effectively alleviate the problem of fuzzy features leading to misclassification. Semantic information and syntactic information are optimized by attention mechanism. Finally, the fused information is input into the Softmax classifier for music sentiment classification. Experimental results on open data sets show that compared with other advanced methods, the recognition accuracy of the proposed method is more than 90%.

Cold regional tunnels have been encountering numerous frost damages as a result of dynamic changes in hydrothermal conditions of tunnel structural layers. The climate change is recognized as a major contributor for the problems. In this study, the hydrothermal conditions of a high speed railway tunnel are evaluated under different climate scenarios based on in-situ data and numerical analysis. Subsequently, the effect of different thicknesses of insulation board on hydrothermal conditions inside the tunnel is compared and the reasonable thickness is obtained. The main findings are: The temperature and unfrozen water content gradually decreased and the ice content gradually increased with the service time of the tunnel in the early 15 years; the maximum frozen depth occurs at the tunnel sidewall and it with a depth of 1.64 m within 30 years after the construction. The hydrothermal conditions inside the tunnel are significantly affected by annu?al mean air temperature (AMAT) and annual range of air temperature (ARAT); the maximum frozen depth decreases with AMAT, but increases with ARAT. After the XPS board with a thickness of 5 cm is laid in tunnel structural layers, the temperature at the most unfavorable position is 0.55?C in the cold season, which suggests that frost damages disappeared and this method can be used to protect the tunnel against the frost damages. This paper can provide a basis for heat insulation design of the cold regional tunnels.

The cement industry is the second largest source of global man-made CO2 emissions after the power industry, and the adoption of O2/CO2 combustion technology for cement kilns is of great significance in reducing CO2 emissions. In this paper, the effects of pulverized coal mixed air combustion and pulverized coal mixed O2/CO2 combustion on the velocity field, temperature field, CO2 and NOx concentration distribution in rotary kiln were investigated by CFD technique. The results showed that there is no difference in the velocity distribution between the two atmospheres, and the speed difference between the primary and secondary air creates a re-circulation zone near the burner. The O2/CO2 atmosphere combustion decreased the maximum temperature, but improved the uniformity of the temperature field. The pulverized coal burnout rate under O2/CO2 atmosphere decreased by 3.55% compared to O2/N2 atmosphere. The mole fraction of CO2 at the rotary kiln outlet is 0.08 and 0.93 for O2/N2 and O2/CO2 combustion atmospheres, respectively. It is easier to achieve CO2 aggregation and capture under O2/CO2 atmosphere than under O2/N2. The NOx concentration at O2/CO2 is approximately one half of that at O2/N2, which can save the investment on denitrification equipment. The simulation results reasonably agree with the measured data. The findings of this work will provide a reference for the generalization and application of the O2/CO2 flue gas cycle calcinating cement technology.

In the person of Bohdan Stepanovych Cherkes, not only the Department of Design and Fundamentals of Architecture, but also the Lviv School of Architecture in general, received a worthy helmsman capable of strategic thinking, analyzing circumstances and drawing correct conclusions, predicting directions for the development of educational processes. In an article dedicated to Bohdan Stepanovych's 50th anniversary, Professor Andriy Rudnytskyi wrote: "...Bohdan Cherkes is a broad-minded personality. He is a good connoisseur of business affairs, specialist, architect, teacher, scientist, knows many languages and is oriented in the development of architecture not only in the universities of Ukraine, but also in other regions of the world... As a person, Bohdan Stepanovych knows how to establish adequate contact with people, benevolent and friendly. As a manager, he has a good sense of the gradation of cases according to their importance, the order in which these cases should be resolved, and knows how to do it. Finally, and this is especially important, Bohdan Cherkes has unquestionable Ukrainian patriotism. Here he acts without unnecessary exaggerations and ostentatious gestures; he loves his homeland not in order to demonstrate it - all his activities are directed towards Ukraine in their essence. He travels a lot around the world, but I am sure that he will never exchange Ukraine for wealth and comfort in other lands." It is hard not to agree with these words of the professor, who during his life had the opportunity to know Bohdan Cherkes both as his student, as a colleague, and as a supervisor. In principle, being in a leadership position, one can act in two ways: a) solve tactical problems, that is, to get out of the current situation and solve it by the currently available means, without particularly thinking about far-reaching consequences; b) act in advance, having a strategic plan, and in accordance with it, initiate certain events. This second option, in our opinion, is the closest for Bohdan Stepanovych. Otherwise, there would not be a "design" specialty within the walls of the Lviv Polytechnic, there would not be an open graduate school, there would not be a specialized academic council for this specialty, and there would not be many other things that everyone has long considered a self-evident element of the daily life of the Lviv school of architecture.
