Tensiones y ambivalencias en los significados sobre el gobierno del tiempo en el emprendimiento: entre la agencia y la sujeción
Authors: Carretero García Carlota
Published: September 2023

En este artículo se analizarán los sentidos en torno al gobierno del tiempo en el emprendimiento a través de las narraciones de mujeres jóvenes emprendedoras. El estudio de este problema de investigación habilita adentrarse, no sólo en la reorganización de los tiempos acontecida a través de la promoción de un nuevo arquetipo de sujeto laboral, el emprendedor, sino en las (dis)continuidades, distancias y ambivalencias en la producción situada de sentido respecto a la promesa de agencia y recuperación de capacidad de auto-organización que moviliza el discurso hegemónico del emprendimiento. Se han llevado a cabo 30 entrevistas semi-estructuradas y se ha optado por un enfoque de análisis crítico del discurso vinculado a los estudios de la gubernamentalidad y la teoría feminista que permite abordar las relaciones de poder y desigualdad, y los sentidos sobre las vivencias y las vulnerabilidades, en las narraciones sobre el gobierno del tiempo en el emprendimiento.

Published: September 2023

Advances in sequencing technologies and declining costs are increasing
the accessibility of large-scale biodiversity genomic datasets. To
maximise the impact of these data, a careful, considered approach to
data management is essential. However, challenges associated with the
management of such datasets remain, exacerbated by uncertainty among the
research community as to what constitutes best practices. As an
interdisciplinary team with diverse data management experience, we
recognise the growing need for guidance on comprehensive data management
practices that minimise the risks of data loss, maximise efficiency for
stand-alone projects, enhance opportunities for data reuse, facilitate
Indigenous data sovereignty and uphold the FAIR and CARE Guiding
Principles. Here, we describe four fictional personas reflecting user
experiences with data management to identify data management challenges
across the biodiversity genomics research ecosystem. We then use these
personas to demonstrate realistic considerations, compromises, and
actions for biodiversity genomic data management. We also launch the
Biodiversity Genomics Data Management Hub
(https://genomicsaotearoa.github.io/data-management-resources/),
containing tips, tricks and resources to support biodiversity genomics
researchers, especially those new to data management, in their journey
towards best practice. The Hub also provides an opportunity for those
biodiversity researchers whose expertise lies beyond genomics and are
keen to advance their data management journey. We aim to support the
biodiversity genomics community in embedding data management throughout
the research lifecycle to maximise research impact and outcomes.

Published: September 2023

Objective: To explore the effects of progestin-primed ovarian
stimulation (PPOS) using fixed versus degressive doses of
medroxyprogesterone acetate (MPA) in conjunction with letrozole (LE) in
infertile women. Design: Retrospective cohort study.
Setting: Tertiary-care academic medical center.
Population: We studied 3173 infertile women undergoing their
first IVF/ICSI treatment from 2017 to 2020. Methods: Propensity
score matching (PSM) analysis was performed with 1:1 in 1068 and 783
patients who underwent a fixed dose of MPA combined with LE and a
degressive dose of MPA combined with LE protocols, respectively.
Main outcome measures: Incidence of premature luteinizing
hormone (LH) surges and number of oocytes retrieved. Results:
We created a perfect match of 581 patients in each group. The dosage of
MPA, premature LH surge, progesterone (P) level and LH level on the hCG
trigger day and LH level on the day after hCG trigger were significantly
higher in the LE + fixed MPA group than in the LE + degressive MPA
group. The E level on the hCG trigger day, the
duration of Gn, the number of oocytes retrieved were lower in the LE +
fixed MPA group than in the LE + degressive MPA group.
Conclusions: Using degressive MPA dose combined with LE could
reduce the total MPA dosage and premature LH surge and increase the
number of oocytes retrieved in women undergoing the PPOS protocol.

Event-triggered Adaptive Estimated Inverse Neural Network Control of Uncertain Nonlinear Systems With Input Hysteresis Nonlinearity
Authors: Yao Jianyong , Zhou Ning , Deng Wenxiang
Published: September 2023

This article investigates an event-triggered adaptive estimated inverse
control scheme for a class of uncertain nonlinear systems with
hysteresis effects, parametric uncertainties and disturbances. An online
estimated inverse hysteresis compensation mechanism is developed, where
an adaptive technique is employed to obtain the value of unknown
hysteresis parameters. Compared with the common approaches, its biggest
advantage lies in that it is not necessary to obtain the hysteresis
parameters by means of experiment, which relaxes time-consuming off-line
identification work.Moreover, an adaptive radial basis functions neural
network (RBFNN) is utilized to approximate the unknown disturbances,
whose weight coefficients along with parametric uncertainties are all
estimated by the adaptive technique. Besides, the communication cost can
be largely saved by introducing the relative threshold event-triggered
control (ETC). Through Lyapunov analysis, the proposed controller
guarantees the boundedness of all the signals and the convergence of the
error signals. The results of numerical simulation illustrate the
effectiveness and superiority of the developed controller.

Published: September 2023

Objective: We aimed to investigate the relationship between
gene polymorphisms and the occurrence of adverse clinical events
following dual antiplatelet therapy in Patients with Symptomatic
Intracranial Atherosclerotic Stenosis. Methods: A total of 195
patients were enrolled, categorized into 32 cases (those with clinical
adverse events) and 163 controls (without events). Genotyping of 20 SNPs
from 17 genes was executed. Statistical analyses (Fisher’s exact test,
logistic regression) were applied to determine associations.
Results: The ITGA2 rs1126643 (C807T) and rs1062535 (G873A)
polymorphisms were significantly correlated with adverse clinical
events. Specifically, the mutant frequency of allele C (ITGA2 rs1126643)
and allele G (ITGA2 rs1062535) was significantly higher in cases
compared to controls (OR = 2.97, 95%CI = 1.702-5.172, P = 0.0001; OR =
3.27, 95%CI = 1.762-6.066, P = 0.0002, respectively). Other genotypes
showed no significant differences between the groups.
Conclusion: The ITGA2 C807T and G873A polymorphisms may elevate
the risk of vascular events in Chinese patients. Detecting these
polymorphisms may be valuable in identifying patients at risk of
recurrent ischemic events.

Separation method of semi-fixed variables together with integral bifurcation method for solving generalized time-fractional thin-film equations
Authors: Rui Weiguo , he weijin
Published: September 2023

It is well known that investigation on exact solutions of nonlinear
fractional partial differential equations (PDEs) is a very difficult
work compared with integer-order nonlinear PDEs. In this paper, based on
the separation method of semi-fixed variables and integral bifurcation
method, a combinational method is proposed. By using this new method, a
class of generalized time-fractional thin-film equations are studied.
Under two kinds of definitions of fractional derivatives, exact
solutions of two generalized time-fractional thin-film equations are
investigated respectively. Different kinds of exact solutions are
obtained and their dynamic properties are discussed. Compared to the
results in the existing references, the types of solutions obtained in
this paper are abundant and very different from those in the existing
references. Investigation shows that the solutions of the model defined
by Riemann-Liouville differential operator converge faster than those
defined by Caputo differential operator. It is also found that the
profiles of some solutions are very similar to solitons, but they are
not true soliton solutions. In order to visually show the dynamic
properties of these solutions, the profiles of some representative exact
solutions are illustrated by 3D-graphs.
Recent advances in rapid screening methods for glycosyltransferases
Authors: Xia Hui , Huang Shengbo , Zhang Zihan , Xue Feng
Published: September 2023

Glycosyltransferases (GTs) are a diverse group of transferases widely
distributed in microorganisms and plants which catalyze the transfer of
glycosyl moieties from activated sugar donors to a diverse range of
acceptor molecules. GTs play important roles in biological processes,
such as cell signal transduction, cell-cell interactions, immune
response and diseases. In addition, the utilization of
glycosyltransferases to synthesize glycosides has become a major area of
pharmaceutical research. The construction of a rapid and efficient
screening method for glycosyltransferases is the key to the successful
discovery, identification, and modification of new enzymes. In the past
few decades, a series of screening methods have been developed to assess
activity. This review focuses on various methods for rapid screening of
GTs, outlining their advantages and disadvantages.
Mutation pressure mediates a pattern of substitution rates with latitude and climate in carnivores
Authors: Zhao Chao , Liu Guangshuai , Yang Xiufeng , Wang Xibao , Zhou Shengyang , Liu Zhao , Liu Kangning , Zhang Honghai
Published: September 2023

The evolutionary patterns of the mitochondrial genome are influenced by
both adaptive and nonadaptive forces, with their contributions varying
among taxa. There appears to be a correlation linking mutagenesis and
latitude, which could be due to differences in metabolic rates. These
discrepancies in metabolic rates exhibit a positive connection with
mutation pressure. On this basis, we hypothesise that nonadaptive forces
play a role in the differences in mutation rates observed along
latitudinal gradients. In this study, we selected widely distributed
carnivores as representatives of mammals to test our hypothesis. We
examined the correlations between the dN/dS ratio (ω), as well as the
substitution rates (dS and dN), of 13 PCGs in the mtDNA of 122
carnivores, and the latitude and climatic factors. We found that taxa
distributed in higher latitudes tend to have higher substitution rates,
but not ω values indicating selective pressure. Notably, dN shows a
strong positive correlation with dS, although dS is primarily influenced
by mutation pressure, while dN is also influenced by effective
population size (Ne). Phylogenetic generalised least squares (PGLS)
regression analyses showed that both substitution rates were correlated
with climatic factors representing the temperature, precipitation and
variability of climate. Based on our findings, we propose that the
mutations are primarily influenced by nonadaptive forces (mutation
pressure). This forms the fundamental premise for natural selection and
speciation. Moreover, the correlation between substitution rates and
latitudinal distribution and climate, which are outcomes of nonadaptive
factors, can aid in comprehending the global distribution of species
diversity.
On the parameters domain of the single-diode model
Authors: Cárdenas-Bravo Carlos , Dutykh Denys , Lespinats Sylvain
Published: September 2023

The I-V curves of solar photovoltaic (PV) systems have been widely used
as a tool to determine their electrical operation. Usually, I-V curves
are described by means of three cardinal points: the short-circuit point
( 0 , I sc ) , the open-circuit point ( V oc , 0 ) , and the maximum
power point ( V mp , I mp ) . In this context, to study the I-V curves,
the Single-Diode Model (SDM) is often used. In this manuscript, we
present a practical approach for determining the parameters domain of
the SDM given a set of cardinal points. An in-depth mathematical
analysis showed that the cardinal points must satisfy the following
inequalities V oc / 2 < V mp < V oc and I sc / 2
< I mp < I sc . Then, it is possible to implicitly
represent the SDM by means of one single parameter in a thoroughly
chosen coordinate space. Based on these theoretical results, a fast
computational algorithm for calculating the SDM parameters limits is
proposed. The algorithm has been computer-tested using 40 000
synthetically generated maximum power points which are processed in
about one minute of the CPU time on a standard laptop computer.
Moreover, as a practical application, the California Energy Commission
database is analyzed using the proposed algorithm.

A Self-constraint Model Predictive Control Method via Air Conditioner Clusters for Min-level Generation Following Service
Authors: Ma Yunfeng , Zhang Chao , Ding Bangkun , Mi Zengqiang
Published: September 2023

As renewable power generation increases in distribution networks, the
real-time power balance is becoming a tough challenge. Unlike simple
peak-load shedding or demand turn-down scenarios, generation following
requires persistent and precise control due to the temporal response
performance of controlled resources. This motivates a comprehensive
control design considering the temporal response limitations and
execution performance of ACCs when providing such services. Accordingly,
this paper proposes a self-constraint MPC that properly allocates the
generation following task among different ACCs, consisting of three main
parts: response rehearsal, distributed consistency-based power
allocation, and real-time task execution. Specifically, the rehearsal
knowledge of ACCs is evaluated by introducing model predictive control
to track power signals with different values and thus obtain prior
factors, including the upward/downward limits and control cost function.
On this basis, the coherence of the incremental response costs of
different clusters is achieved by containing the prior factors to model
the constraints and cost functions. Once the optimised following signals
are obtained, a real-time model predictive controller for generation
following task execution is employed. Simulations are conducted to
verify the feasibility and effectiveness of the proposed method.
Fueling Neuroblastoma: Genomic Analysis of Ketolytic and Glycolytic Gene Expression in Relation to MYCN Oncogene Amplification, Stage, and Prognosis
Authors: Molloy Joseph W. , Lee David , Downer Eric , Barry Denis
Published: September 2023

Background Neuroblastoma (NB) is a childhood cancer of the sympathetic
nervous system, and its prognosis is poor. NB undergoes transcription
changes to use aerobic glycolysis as its primary metabolic pathway.
Aerobic glycolysis provides an immediate source of ATP in metastasis
proliferation, and therefore may be exploited in dietary therapies, such
as the ketone diet. Procedure In this study, the expression of
glycolytic and ketolytic genes in the context of MYCN oncogene
amplification, tumor staging, and Kaplan-Meier survivability was
investigated using the R2: Genomics analysis and visualisation platform
(http://r2.amc.nl). The R2 database is a platform for gene expression
and prognostic data for primary tumour samples. Six NB genomics datasets
were accessed and further analysed in GraphPad Prism to investigate the
relationships between glycolytic and ketolytic gene expression and
prognosis. Results Glycolytic gene expression is increased in
MYCN amplified, metastatic tumours, and is associated with worse
event free survival. Ketolytic gene expression is lower in metastatic
tumours and is associated with better event free survivability. The
glycolytic gene expression profile of NB suggests that elevated levels
correlate with tumorigenicity and low probability of survival. Ketolytic
gene expression patterns suggest a decreased reliance for ketolytic
energy, which may be exploited to slow tumorigenic growth. Conclusions
This study validates the glycolytic gene expression profiles in
metastatic and MYCN-amplified NB tumours and suggest the potential use
of these genes in prognosis prediction. Furthermore, the study
highlights the reliability and utility of the R2 database as an
oncogenomic tool for NB research.
Optimization Strategy for Incentive-Based Integrated Demand Response Considering Multi-Dimensional Coupling Characteristics of Consumers
Authors: Xu Gang , Guo Zixuan , Zheng Shunlin
Published: September 2023

Integrated Demand Response is increasingly recognized as a crucial tool
for maintaining balance between supply and demand in integrated energy
systems, and for enhancing the absorption and utilization rate of
renewable energy. A prerequisite for implementing IDR effectively is the
accurate modeling of consumer characteristics. However, existing models
have not accounted for the coupling characteristics of inter-energy
comfort and inter-period incentives when consumers participate in IDR;
they also overlook the Inter-consumer coupling characteristics. This
paper presents an inter-energy comfort coupling matrix and a
cross-elasticity coupling matrix for incentives, offering effective
modeling of the coupling characteristics between different energies and
periods. By introducing a dynamic participation rate, a mathematical
model of inter-consumer coupling characteristics is established.
Simulation results demonstrate that the model considering inter-energy
coupling characteristics produces significant reductions in response
power deviations and total costs of IESP, while also enhancing consumer
motivation to participate in IDR. The model that incorporates
inter-period coupling characteristics not only improves consumer
benefits and comfort levels in participating in IDR but also further
reduces response power deviations and total costs of IESPs. The model
considering inter-consumer coupling characteristics effectively
mitigates response power deviations resulting from consumers’ bounded
rationality by calculating the mathematical expectation of each
consumer’s response power.
Land-Ocean Links in Major Watersheds: Deciphering Primary Productivity Responses to Human Interventions and Environmental Changes
Authors: Garcia Cynthia , Berkelhammer Max
Published: September 2023

Open watersheds and their rivers play a pivotal role in biogeochemical
cycles, forming crucial links between land and ocean ecosystems. This
study utilized remotely sensed and reanalysis datasets to investigate
the land-ocean Gross Primary Productivity (GPP) dynamics of 15 major
watersheds: Mississippi, Nelson, St. Lawrence, Amazon, Parana, Congo,
Zambezi, Niger, Orange, Ganges Brahmaputra, Yangtze, Huang He, Amur,
Danube, and Murray Darling. It looked at the dynamics and
vulnerabilities of major watersheds to identify the influences of land
use and land management, moisture balance, and temperature on the
patterns of how primary producers absorb CO2 from the atmosphere.
Intensive human interventions, particularly in agriculture-dominant
watersheds like Mississippi, Ganges Brahmaputra, Yangtze, Huang He, and
Murray Darling, were observed to substantially influence land
productivity, with consequent cascading effects on adjoining ocean
ecosystems. In contrast, the vast rainforests of Amazon and Congo
illuminated their intrinsic vulnerability to moisture dynamics,
accentuating potential threats under shifting climatic regimes.
Watersheds like the Parana and Zambezi offered insights into ecosystem
susceptibilities arising from temperature variations. As climatic
anomalies continue to redefine land-ocean interactions, our study not
only underscores the imperative for adaptive conservation strategies but
also to study adjacent land and marine systems as intricately linked
entities.
Increased runoff from Siberian rivers leads to Arctic wide freshening
Authors: Weiss-Gibbons Tahya , Tefs Andrew , Hu Xianmin , Stadnyk Tricia A. , Myers Paul G.
Published: September 2023

The effects of contemporary increases in riverine freshwater into the
Arctic Ocean are estimated from ocean model simulations, using two
runoff data sets. One runoff data set which is based on older
climatological data, which has no inter-annual variability after 2007
and as such does not represent the observed increases in river runoff
into the Arctic. The other data set comes from a hydrological model
developed for the Arctic drainage basin, which includes contemporary
changes in the climate. In the pan-Arctic this new data set represents
an approximately 11% increase in runoff, compared with the older
climatological data. Comparing two ocean model runs forced with the
different runoff data sets, overall changes in different freshwater
markers across the basin were found to be between 5-10%, depending on
the area investigated. The strongest increases were seen from the
Siberian rivers, which in turn caused the strongest freshening in the
Eastern Arctic.
Molecular Marker Based Genetic Diversity Study of Curcuma Caesia Roxb. – A Mini Review
Authors: S Sahoo
Published: September 2023

The availability of genetic resource provides an opportunity for plant breeders to develop new cultivars with desirable characteristics and these characteristics encompass various traits preferred by farmers (high yield potential, larger seed size, etc) as well as traits favored by breeders (pests and disease resistance). Genetic resources are also essential for conservation, as they provide a basis for identifying threatened species and developing conservation strategies. Curcuma caesia Roxb. (Zingiberaceae) is an underutilized perennial herb with bluish-black tuberous rhizome having the characteristic of aromatic and medicinal properties. There is an ample genetic diversity of Curcuma plants with medicinal importance around the world. Authentication and ensuring the genuineness of Curcuma are crucial aspects for marker-based analysis. Therefore, genetic variation serves as the base for the identification and characterisation of the plants. Molecular marker technology is widely used in genetic diversity analysis, germplasm resource identification, and molecular marker-assisted breeding technique. Multiple molecular markers have been used for characterization and identification of species for its sustainable utilization and conservation. The molecular investigation, which involves techniques like RAPD, SCAR, ISSR, and AFLP for fingerprinting, plays a crucial role in establishing molecular markers to assess the authenticity and diversity of plant species. Various marker analyses have demonstrated a significant degree of genetic variation among the species and these patterns tend to differ due to environmental influences and genetic factors. This review facilitates a complete information about the molecularassisted genetic diversity study of Curcuma caesia Roxb. (Black turmeric) which may be used as a database while exploring the diversity analysis.

Housing markets are search markets and, thus, the relation between housing need and trading frictions deserves a lot of attention. Design/methodology/approach: To study the relation between housing need and trading frictions, this theoretical paper develops a search and matching model. To the best of our knowledge, this is the first paper that addresses the topic by the search and matching theory. Findings: The model finds that only in a case the supply side’s profit maximisation condition coincides with the housing need satisfaction. In general, therefore, search markets are not able to satisfy the housing need. Housing policies that protect the weaker side (the demand side) of the market are thus needed. Policy implications: Housing policies can increase the “actual” and the “realised” housing demand, but a “potential” housing demand remains unsatisfied. Hence, labour market policies that increases both employment and wages are also needed. Originality/value: To the best of our knowledge, this is the first paper that analyses the housing market equilibrium with search frictions from the perspective of “non-well-off first-time buyers”. Research limitations/implications: This model represents a first theoretical attempt to study the housing need by the search and matching framework. Future studies, therefore, should further develop the theoretical model by considering the close link between housing and labour markets.

The pseudo-fruits of Dog Rose are a rich source of L-ascorbic acid and several other active substances, which means their high supportive therapeutic potential. The study aimed to examine the impact of the chosen technological procedure for the preparation of tablets containing rosehip powder on the amount of L-ascorbic acid in the final pharmaceutical form. Drying of the plant drug was performed at room temperature to avoid possible thermal degradation of this heat-sensitive compound. Similarly, drying of the granules after wet granulation in the oven was replaced by natural drying at room temperature. The composition of two types of prepared granule formulations differed in the filler – lactose (LAC) or microcrystalline cellulose (MCC). Apart from the disintegration test, they meet the technological requirements for granules or tablets. Lactose was confirmed as a more suitable filler, which despite the unsuccessful disintegration of the granules, ensures the disintegration of tablets within 15 minutes even without the addition of a special excipient acting as a disintegrant. The content of L-ascorbic acid detected using isotachophoresis – capillary zone electrophoresis was 87.16 ± 5.06 µg in LAC tablets and 63.33 ± 2.83 µg in MCC tablets.

Authors: Guo Jian , Chen Xue
Published: September 2023

This paper aims to conduct a systematic study on the career development and planning system of counselors in private colleges and universities in the new era. This study analyzes counselors’ cognition of career development with the help of Schober’s career development theory, analyzes counselors’ career planning through career choice theory, explores the influencing factors of college counselors’ careers based on the division of career development stages, and analyzes the degree of influence of different factors on counselors’ career development based on the ecological position model. When counselors make career planning, their factors are the most important, which are 4.5%, 9.06%, 22.46%, and 32.48%, higher than school factors, social factors, family factors, and role orientation, respectively. In terms of the degree of influence, the promotion policy and management system of private colleges and universities have the greatest influence on the career development of counselors, followed by the professional background and subjective will of counselors. Counselors in private colleges and universities should strengthen their career autonomy, improve planning techniques and methods to turn passivity into initiative and win career development opportunities, prepare career growth manuals, and strengthen career planning awareness.
Research on the development of watercolor painting education in universities based on smart contract model
Authors: Wu Jiaming
Published: September 2023

Facing the information era of rapid development of the Internet, university watercolor education is in urgent need of finding a new development direction. Through the emerging education model of Internet+education, this paper regards knowledge sharing as the transaction behavior of buyers and sellers in the knowledge market and establishes a smart contract model based on the knowledge supply and demand functions. A blockchain knowledge-sharing-based watercolor painting classroom model is proposed to break the traditional teaching role and apply it to the teaching and practical analysis of watercolor painting in universities. With the Internet+ education model, the teaching diversity increased by 26.90%, and the teaching interactivity increased by 6.12% compared with the original. Nearly 60% of the students thought that the teaching effect of the Internet+ education mode was improved. In the teaching practice, the students’ watercolor painting works received 7.53% more A grades in color usage compared to the original. For the evaluation of spatial level, the students who received A grades increased by 18.76% compared to the original. The Internet+ education model provides a new path for the development of university watercolor painting education, which helps cultivate watercolor painting artistic talents with both inclusive artistic thoughts and unique personal artistic characteristics.

As an important component of the hydraulic system, the performance of the hydraulic pump and motor greatly influences the performance of the whole hydraulic system, so it is necessary to study the hydraulic pump and motor test system. In this paper, the design of the mechanical power recovery hydraulic pump motor test system is completed through theoretical analysis and calculation; and the AMEsim simulation software is used to numerically simulate the test process of the hydraulic pump and motor test system, analyze the system loading method of the test system, recovery efficiency and simulation of typical working conditions; meanwhile, the control strategy of adjusting the single variable motor displacement to control the minimum overflow of the system is simulated and analyzed Simulation analysis is also performed for the control strategy of adjusting the univariate motor displacement to control the minimum overflow. Simulation results show that: the recovery efficiency of the mechanical power recovery hydraulic pump motor test system varies with the size of the overflow; when the system is the minimum overflow value, the optimal recovery efficiency of 75% is achieved, and the recovery performance is improved by 32% compared with other power methods. The mechanical power recovery hydraulic pump motor test system designed in this paper solves the shortcomings of high energy consumption, low recovery efficiency, and small application range of the previous single way of loading; at the same time, based on meeting the function and performance, the hydraulic pump and motor test system are integrated into one system, and the applicability and scalability are significantly improved.
Reform and innovation of saxophone teaching mode in colleges and universities based on Bayesian model
Authors: Lyu Yukun , Hou Ying
Published: September 2023

To improve the teaching level of saxophone performance in colleges and universities, this paper constructs a saxophone performance education optimization platform based on Bayesian theory. Bayesian clustering is used to informally cluster the saxophone performance education situation in colleges and universities, and the maximum likelihood algorithm is used to calculate the student behavior parameters. The Bayesian network tracking technique analyzes all learning behavior indicators to serve as a reference to obtain labels of learner motivation. To ensure the validity of the feedback metrics, the Bayesian stochastic calculation method was invoked to calculate the AUC (metric) mean ratio of the three feedback metrics. A practical teaching analysis was conducted to verify the platform’s timeliness. The results show that: The response time of login and resource search of the platform constructed in this paper is less than 2.5s and 1.2s, respectively, and the AUC mean ratio of three feedback metrics, namely, download rate, registration rate, and click rate, has improved by about 0.75%. Moreover, the positive attitude of university students towards learning has reached 88%. This shows the reliability of the educational platform constructed in this paper in optimizing higher education saxophone performance education, which can effectively improve the teaching level of saxophone performance education.

In this paper, we study the multimodal discourse of automotive websites, aiming to contribute to the improvement and upgrading of automotive websites. To this end, this paper mines the data of advertising discourse, website visual effect, and feedback of auto website usage based on the KNN algorithm optimized by K-value selection strategy and analyzes the language effect of advertising discourse, rhetorical techniques, website page design, feedback of usage, and website advertising visual effect of the auto website with the help of multimodal discourse analysis framework. In terms of language, most of the page language and advertising language are concerned with syllabic symmetry, harmonization, and rhyming and focus on rhetorical techniques, such as 21% of the ads use similes and 14% use puns. In terms of content, more than 80% of people were satisfied with the design of the website and felt that the design of the website pages was reasonable, simple, and generous, and the ratio of positive to negative markers such as “satisfaction points” and “car quality evaluation” was close to 7:3, indicating a good recognition. The ratio of positive to negative marks for “satisfaction points” and “car quality evaluation” is close to 7:3, indicating good recognition. In terms of visual design, more than 80% of people think that video ads on auto websites are very effective and can arouse audiences’ interest and make them participate in them actively. Although the overall satisfaction of Chinese auto websites is good, there are many areas for improvement, and these aspects need to be optimized to present better results.
