A semiotic view of symbol and identity in the film Farewell My Concubine
Authors: Zhu Wenxi 
Published: March 2024

Abstract
Adapted by Li Bihua and Lu Wei and directed by Chen Kaige, Farewell My Concubine was first released in mainland China and Hong Kong in 1993. It gained strong momentum and went on to break the box office for mainland Chinese literary films in the USA. Against the background of traditional Peking Opera culture, the film spans nearly half a century and follows the love–hate relationship between Cheng Dieyi, played by Leslie Cheung, and Duan Xiaolou, played by Zhang Fengyi. It shows the changes in human nature and the rise and fall of classical art in the city of Beiping in different eras. Taking “symbols” as the entry point, this paper analyses and explores the characteristics of the cultural symbols and metaphors that accompany the main narrative line of the film so as to further trace and understand the multiple interpretations that “anti-identity construction” brings to the film, as well as the ethical implications reflected in the symbols.
On the syntax and semantics of sluicing in Mandarin Chinese
Authors: Wang Chengdong , Yuan Yudi 
Published: March 2024

Abstract
This article investigates the syntax of sluicing in Mandarin Chinese, including the syntactic constraints on predicates that might appear in sluicing, the reclassification of wh-phrases, the syntactic status of shi ‘be’ and you ‘have,’ and the syntactic derivation of typical sluicing and pseudo-sluicing. This article argues that there are both pseudo-sluicing and typical sluicing in Chinese, with each involving different structures and derivations and requiring different analysis.
Rational intuition: a study on semiotic subjectivity
Authors: Zhang Jie , Yao Tingting 
Published: March 2024

Abstract
Although scientific research usually emphasizes objectivity unaffected by any form of subjectivity, semiotic inquiries have to consider the role of subjectivity. In fact, social development, art, and literature always follow certain rules of objectivity, but these rules seem to be inescapably linked to the subjectivity of human beings. How can we avoid the subjectivity of research, or research biases caused by subjectivity, to ensure the objectivity of scientific research to the greatest possible extent? This paper answers the question through the cultural semiotics of jingshen, which is grounded in Chinese cultural traditions, especially the philosophies of Lao Tseu and Chuang Tzu. This line of inquiry seeks to identify objectivity in the constant transformation between the subject’s states of self and selflessness, while striving to avoid inductive and deductive biases caused by the “conceit” of rationality and to eliminate the constraints of specific concepts and images formed by existing knowledge as well as possible consequential “Verborgenheit.” The purpose is to achieve a state of “rational intuition,” returning to the natural mode of human existence and forging for semiotics a rationality-based path to the intuitive understanding of meaning.
Real-time semantic segmentation based on BiSeNetV2 for wild road
Authors: Chen Honghuan , Lan Xiaoke 
Published: March 2024

AbstractState-of-the-art segmentation models have shown great performance in structured road segmentation. However, these models are not suitable for the wild roads, which are highly unstructured. To tackle the problem of real-time semantic segmentation of wild roads, we propose a Multi-Information Concatenate Network based on BiSeNetV2 and construct a segmentation dataset Dalle Molle institute for artificial intelligence feature segmentation (IDSIAFS) based on Dalle Molle institute for artificial intelligence. The proposed model removes structural redundancy and optimizes the semantic branch based on BiSeNetV2. Moreover, the Dual-Path Semantic Inference Layer (TPSIL) reduces computation by designing the channel dimension of the semantic branch feature map and aggregates feature maps of different depths. Finally, the segmentation results are achieved by fusing both shallow detail information and deep semantic information. Experiments on the IDSIAFS dataset demonstrate that our proposed model achieves an 89.5% Intersection over Union. The comparative experiments on Cityscapes and India driving dataset benchmarks show that proposed model achieves good inference accuracy and faster inference speed.
Novel robot arm concept for lightweighting high-performance machinery
Authors: John Kevin , Fletcher Simon , Furness Thomas , Longstaff Andrew P , Needham Paul 
Published: March 2024

AbstractTo improve the efficiency of robots, a novel sustainable design of a robotic arm is proposed that can address the thermal, vibration, energy usage and dynamic stiffness issues. The proposed design utilises easy-to-produce carbon fibre tubes including some that are commercially available, for the robot link instead of traditional materials, which can be heavy and carbon intensive. The design involves arranging several carbon fibre reinforced polymer (CFRP) tubes in a specific array inside an epoxy resin substrate. Based on this design, a Finite Element Analysis (FEA) was implemented demonstrating the relatively low mass and high stiffness characteristics. Design optimisation was then performed using custom generated MATLAB®code to reduce the computation time. The proposed design for a one-meter-long robot link with a diameter of 108 mm offers a stiffness of 0.75 N/μm. A structural steel link, with the same stiffness, is 33 % heavier than the concept design. The design maintains thermal stability with about a third of the thermal deformation seen in structural steel.

Abstract

Objectives
To investigate the association between birth weight to placental weight (BW/PW) ratio, and echocardiographic left ventricle (LV) morphology at birth, while accounting for other relevant perinatal factors.

Methods
A prospective cohort study was conducted on neonates at NewYork-Presbyterian Brooklyn Methodist Hospital from 2014 to 2018, categorized by their BW/PW percentile. Missing data were imputed with principal component analysis. Chi-squared and one-way analysis of variance were used to compare BW/PW groups and the best regression model was selected using a genetic and backward stepwise algorithm.

Results
We analyzed 827 neonates in three BW/PW groups: small (n=16), normal (n=488), and large (n=323). Placental thickness and smallest diameter were positively correlated with several LV parameters, including inter-ventricular septal thickness during diastole (IVSd) (p=0.002, p<0.001) and systole (IVSs) (p=0.001, p<0.001), LV posterior wall thickness at end of diastole (LVPWd) (p=0.003, p<0.001) and systole (LVPWs) (p<0.001, p<0.001), LV mass (p=0.017, p<0.001), and LV mass/volume (p=0.011, p<0.001). The BW/PW ratio correlated with an increased shortening fraction (estimate=0.29, 95 % CI 0.03–0.55, p=0.027). PW correlated with IVSs (p=0.019), while the longest placental diameter was linked to a decrease in LV internal dimension during diastole (LVIDd) (estimate=−0.07, p=0.039), LV mass (estimate=−0.11, p=0.024), and LV mass/volume (estimate=−0.55, p=0.005).

Conclusions
This study found that several placental factors, including the BW/PW ratio, can independently affect LV dimension and morphology, highlighting the importance of fetal growth and placental health in the physiological adaptation of the fetal heart. More research is needed to establish causation and inform newborn prevention strategies.

Abstract
The current study proposed a novel simple and environmentally friendly approach for producing silver nanoparticles (AgNPs) using an extract of Moringa oleifera leaves (MOL) and optimizing the different experimental factors required for the formation and stability of AgNPs. The formation of nanoparticles was confirmed by a color change from yellow to reddish-brown with a surface plasmon resonance band at 412 nm. The morphology, size, and elemental composition of AgNPs were investigated by zeta potential dynamic light scattering, field emission scanning electron microscopy, energy dispersive X-ray, X-ray diffraction, and transmission electron microscopy analysis, which showed crystalline and spherical AgNPs. The identification of functional groups was supported by Fourier-transform infrared spectroscopy. The photocatalytic activities of AgNPs were assessed in the degradation of organic Malachite green (MG) dye in the aqueous solution. Two kinetic adsorption models, the pseudo-first-order model and the pseudo-second-order model, and three isotherm models, the Langmuir, Freundlich, and Temkin, were used to mathematically characterize the MG degradation process. The pseudo-second-order kinetics and the Freundlich isotherm model were found to be in good agreement with the experimental data. As a result of their synergistic interaction with the MOL extract solution, the photocatalytic activity of AgNPs increases and they can successfully adapt to the photodegradation of organic dyes in industrial effluents.
A unitary account of indicative/subjunctive mood choice
Authors: Marques Rui 
Published: March 2024

Abstract
In some finite clauses only one of the subjunctive and indicative moods might occur, while in others there is option between these two moods. This is the basic distinction between intensional and polarity subjunctive. This paper questions the sustainability of such division in Portuguese, providing a critical analysis of the major arguments sustaining that those two types of subjunctive need to be considered. Instead, it is shown that a semantic analysis of the indicative and subjunctive moods accounts for the distribution of these moods in European Portuguese (EP), no different explanations being needed for the cases of lexical selection and those of mood choice. In both cases Indicative signals that only p-worlds are taken in account, while Subjunctive signals the consideration of non-p worlds. This allows a comprehensive account of the EP data: Subjunctive or Indicative occurs depending on whether the meaning of the sentence leads to the consideration of non-p worlds or not. However, in other varieties of Portuguese, Indicative occurs in some sentences whose meaning involves the consideration of non-p worlds. Such is the case of Brazilian Portuguese (BP), where, in colloquial speech, the use of Indicative is common in complement clauses of querer (‘to want’), a paradigmatic domain of Subjunctive. The conjecture is made that in this variety resorting to one or another mood is used as a pragmatic, discursive, strategy, even if the meaning of the sentence leads to the other mood.
Should Courts Decide Climate Policies?
Authors: Lando Henrik 
Published: March 2024

Abstract
In State of the Netherlands v. Urgenda Foundation (the Urgenda verdict), the Dutch Supreme Court ordered the Dutch Government to pursue a goal of a 25 % rather than a 20 % decrease in CO2 emissions. The present article discusses the verdict and climate litigation of this kind more generally from a functional perspective rather than from the perspective of democratic legitimacy. It argues that the premises of the Court were inapplicable from an economic perspective and that the faulty reasoning is indicative of reasons why judicial restraint is socially desirable in the area of climate policies. From the viewpoint of social welfare, it may be desirable that a court overrides climate policy if the policy neglects the interests of future generations, i.e. if it is unsustainable. However, the Court did not consult the economic literature on sustainable climate policies. It relied on a consensus among climate scientists, on the European Convention of Human Rights, and on the precautionary principle. We argue that if the Court had consulted the economic literature, it would have found disagreement about how quickly emissions should be lowered, and it would have had to address many complex sources of disagreement that cannot be eliminated by recourse to human rights or the precautionary principle. The Court would have had to subjectively assess different economic theories. However, the litigation process is not set up for and judges are not trained for this complex assessment.
DEVELOPMENT OF RISK ASSESSMENT METHODS IN THE IMPLEMENTATION OF EXPLORATION PROJECTS
Authors: Imamov R. R. 
Published: March 2024

The peculiarity of oil and gas projects is their long implementation period, during which they are subject to the influence of a large number of different risk factors that complicate project implementation and result in failure to achieve the planned economic indicators set by investors. The effective operation of companies therefore depends on how reliably investors can predict the prospects for project development. The success of the subsequent functioning of the investment project depends to a large extent on the reliability of the assessment of the effectiveness of the investment project, based on the optimally chosen strategy of its development, and, above all, on the anticipation of possible risk factors and tools for their prevention. Therefore, at present, the competitive struggle in the oil and gas production industry is currently shifting to the area of pre-project preparation of investment projects and increasing the reliability (quality) of their economic efficiency assessment at the stage of making a decision to start their implementation.Geological risks become important in the implementation of exploration projects, the first stage in the overall process of developing the Company's assets. It is necessary to find a balance between the cost of project implementation and the amount of accumulated hydrocarbons for the forecast period, which will ensure maximum profitability of the project. The challenge to optimize the financial outlay on the implementation of geological exploration works by focusing on the most promising and important projects for companies becomes relevant. In this regard, the article considers the methodological approaches proposed by the author to assess the risks of exploration with the aim of improving the efficiency of the planning process and reducing inefficient financial costs.
THE USE OF DIGITAL TWINS TO IMPROVE THE OPERATIONAL EFFICIENCY IN THE EXTRACTIVE INDUSTRIES
Authors: Svadkovsky V. A. 
Published: March 2024

The article examines the impact of Digital Twins on the business processes of mining companies. Mining companies can optimise their operations, from stripping and mining to enrichment and transportation. By modelling different scenarios, identifying bottlenecks and making informed decisions, companies can improve resource efficiency, reduce downtime and increase productivity, making a positive impact on their operational efficiency. Predictive maintenance strategies implemented with the help of Digital Twins help increase efficiency by minimising unexpected equipment failures and maximising uptime.The main technological effects of the use of Digital Twins in the mining industry, which affect the operational efficiency of the company, are: (1) an increase in the volume of output of commercial products after coal enrichment; (2) an increase in the coefficient of output to the production line of mining equipment.These effects lead to an improvement in the operating efficiency of the mining company, which increases indicators such as EBITDA and cash balance at the end of the period. This impact on operating efficiency is achieved by increasing the volume of commercial products, improving the efficiency of production processes, and by reducing the fixed and operating costs of the business.In order to assess the impact of the use of Digital Twin technology on mining companies, a methodology has been developed to assess the impact of the use of Digital Twin technology on mining companies. According to the results of the survey, a number of key production processes have been identified where the introduction of a Digital Twin is expected to have an impact.As a result of the empirical study, the expected increase in EBITDA from the implementation of the Digital Twin was 28%, the actual increase in EBITDA over the study period was 21%. The expected increase in free cash at the end of the period was + 593 million rubles (+130%), the actual increase in free cash for the period under study was 441 million rubles (+96%).The introduction of Digital Twins in mining companies has shown great potential for improving operational efficiency and solving complex challenges facing the industry.
Staging and Grading of Oral Squamous Cell Carcinoma
Authors: Nagar Dr. Preeti , Sadiq Dr. Heena 
Published: March 2024

Oral cancer is the 8th and 13th most common malignancy in the world for males and females, respectively. Globally, over 90% of malignancies affecting the mouth and maxillofacial region are oral squamous cell carcinomas (OSCC), 80-90% of which are associated with tobacco and alcohol use. The oral cavity being the first entry point for various carcinogens is a common site for occurrence of OSCC. The major subsites affected by OSCCs are the lips, anterior tongue, floor of mouth, buccal mucosa, upper and lower alveolar ridges, hard palate, and retromolar trigone. The 5-year survival rate from OSCCs has not significantly improved in the past 30 years, remaining at approximately 50%. These facts underscore the need to explore for factors with prognostic bearing in OSCCs in order to better tailor their individual management.

The effect of hip shoulder width ratio and vertebral column length on sensory level in term participants posted for lower segment caesarean section under spinal anaesthesia in Indian population: A prospective observational study
Authors: Pisekar Kiran Kishor , Dongre Vaibhao , Rasalam Sherin , Chakravarthy Supriya , Shah Pratik 
Published: March 2024

Hypotension is the most common complication of spinal anesthesia with high intrathecal spread of local anaesthetic drug especially during caesarean section. Hip Shoulder width Ratio (HSWR) is one of the factors which affects spread of spinal anaesthesia.85 ASA II participants with singleton term pregnancy undergoing elective caesarean section received 12mg hyperbaric bupivacaine intrathecally with 26G Quincke’s spinal needle in L3-4 intervertebral subarachnoid space via midline approach. Post spinal anaesthesia haemodynamic parameters were monitored every 5 minutes for the first 20 minutes and at the end of surgery. Sensory level was assessed by a pinprick test every 5 minutes till 20 minutes and post-surgery. Hypotension was defined as 20% fall from baseline systolic blood pressure at 15 minutes post spinal anaesthesia.We found significant positive correlation between high shoulder width ratio and highest sensory level achieved (p - 0.0005) using mutiple regression analysis and pearson's correlataion. With every unit increased in high shoulder width ratio spinal level significantly increased by 5 units. Hip shoulder width ration and age were significantly correlatwd with incidence of hypotension.Hip-shoulder Width Ratio has a positive effect on cephalad spread of spinal anaesthesia and thus incidence of hypotension. By knowing the Hip-shoulder Width Ratio, it can help anaesthesiologists to predict the spread of spinal anaesthesia and titrate the dose of 0.5% hyperbaric bupivacaine.

Published: March 2024

Post-operative pain relief following pediatric abdominal surgery is of paramount consideration and caudal block is still a popular, easy as well as safe analgesic technique for effective analgesia in children. With the advent of newer local anaesthetics, there has been a renewed interest in pediatric caudal blocks after lower abdominal surgeries following general anaesthesia. The aim of our study was to compare the efficacy and duration of postoperative analgesia using caudal Ropivacaine and Levobupivacaine in pediatric patients undergoing infraumbilical surgery under general anaesthesia.: The study was conducted on sixty, ASA grade 1, pediatric patients of age 2 to 6 years, of either sex, posted for elective infraumbilical surgery under general anaesthesia. They were randomly divided in two groups of 30 patients each. Group 1: - (n = 30) received caudal block with injection Ropivacaine, 0.25%, 1ml/kg. Group 2: - (n = 30) received caudal block with injection Levobupivacaine, 0.25%, 1ml/kg. Comparative, randomized, single blinded, observational study. : The demographic data was comparable in both the groups. Postoperatively, the quality of analgesia was assessed by the MOP (Modified Objective Pain Scale) score. Duration of postoperative analgesia was assessed by noting the time of giving rescue analgesia in the post-operative period. We also noted side effects, if any in both the groups. The quality of analgesia was found to be similar with both the drug groups (p value &#62;0.05). The duration of analgesia was longer and statistically significant (p value = 0.0006) in the Ropivacaine group (8.43 ± 0.77 hours) as compared to the Levobupivacaine group (7.03 ± 2.03 hours). Statistically significant difference (P value = 0.026) was seen in the requirement rescue analgesia between Ropivacaine (3.33%) and Levobupivacaine (26.67%) groups. There were no major side effects in either of the groups, apart from a single patient out of 30 patients of Levobupivacaine group who had vomiting, compared with none in the Ropivacaine group.We conclude that caudal block with 0.25% Ropivacaine has a longer duration of action as compared to 0.25% Levobupivacaine in children undergoing infraumbilical surgery under general anaesthesia. Both Ropivacaine and Levobupivacaine, have similar quality of postoperative analgesia and side effect profile.
