Design of ROS Robot Tracing Navigation Control System Based on Virtual Navigation Paths
Authors: Zhou Lijun , Li Gang 
Published: July 2024

Abstract

With the rapid development of robot technology, more and more robots are being applied to various complex environments, such as intelligent transport vehicles in the logistics industry, greeting robots in the service industry, and sweeping robots. These robots need to move along specific routes, so it is crucial to develop an effective robot tracing navigation control system. In this paper, a robot tracing navigation control system based on virtual navigation paths is proposed to address the problems of existing robot tracing navigation systems, which are susceptible to environmental influences, have poor robustness, poor controllability, and low navigation accuracy. The system obtains the surrounding environmental information of the robot, builds a map using Simultaneous Localization and Mapping (SLAM) methods, and builds a virtual navigation route based on this map. It then adjusts the motion state of the robot in real-time to move along the virtual navigation path. Experimental results show that the tracing navigation method of this system has strong robustness, high navigation accuracy, and good controllability, making it suitable for robot tracing navigation in complex environments.

Abstract

Background The COVID-19 pandemic has led to a significant reallocation of healthcare services, focusing on pandemic response and emergency preparedness. The Oman Ministry of Health has implemented various measures to combat and control COVID-19. However, this shift has harmed routine outpatient appointments, particularly for chronic diseases such as Diabetes mellitus (DM) and hypertension (HTN). Considering this, our study aims to determine the specific effects of the pandemic on diabetes control, focusing on glycated haemoglobin (HbA1c), blood pressure (BP), lipids (mainly low-density lipoprotein (LDL), weight/ Body mass index (BMI), and compare these to pre-pandemic levels.Methods A retrospective cohort study of 223 diabetic patients aged 20–95 years who had a blood workup in 2019 and 2020 and were registered in Al-Khuwair Health Centre from March to December 2020. Data was extracted from the Al Shifa 3plus System and National Diabetic Register (NDR). SPSS was used to analyse the data.Results Out of 260 patients with diabetes, 223 were included in the study, and 37 were excluded (new DM patients and existing patients without follow-up in 2019). The results showed significant HBA1C, Systolic BP, and BMI changes between 2019 and 2020. The mean HbA1c in 2019 (6.9%) was lower than in 2020 (7.2%). Similarly, the mean SBP in 2019 (131.22 mmHg) compared to 2020 (134.84 mmHg), mean BMI in 2019 (30.49), whereas in 2020 (30.80). The LDL and diastolic BP did not change.Conclusion The COVID-19 pandemic affected healthcare systems globally, and it was not only the direct impact of the virus that caused the consequences or mortalities; it could also be the modifications in priorities. Due to the interruptions in inconsistent care, consequences of non-communicable diseases (NCDs) were advertised. Future strategic plans should be prepared and implemented to manage NCD cases in case of pandemics.
Optimizing Urban Safety: Leveraging Vector Databases, Real-Time Sentiment Analysis, and Large Language Models for Enhanced Route Planning and Crime Prevention
Authors: Gupta Yash 
Published: July 2024

Abstract

Navigating urban environments safely is increasingly challenging in today's complex cities. This paper introduces an innovative method for enhancing urban navigation safety through the utilization of advanced vector embeddings derived from Los Angeles Police Department (LAPD) crime data, stored within a sophisticated vector database. Our innovative method surpasses traditional safety measures by enabling precise semantic querying, significantly improving route prediction accuracy, assisting law enforcement in resource deployment optimization, and enhancing crime prevention strategies.
Our system provides the general public with cutting-edge route recommendations that integrate detailed analyses of crime patterns and contextual information, offering valuable insights for safer navigation. Moreover, through the fusion of real-time crime data from social media and safety apps with a Large Language Model (LLM), we create a Retrieval-Augmented Generation (RAG) application that provides dynamic, context-aware safety insights. Our findings demonstrate that this innovative approach not only enhances the effectiveness of safety recommendations but also revolutionizes urban safety management, representing a substantial advancement in both crime prediction and resource allocation.
Optimal Surface Defect Detector Design Based on Deep Learning for 3D Geometry
Authors: Suh Sangmin 
Published: July 2024

Abstract

Steel-manufacturing sites are extremely harsh and dangerous environments. Visibility is reduced by dust, water vapor, oil, and low light conditions. Additionally, the steel products from hot furnaces have surface temperatures ranging from 1200 to 800 degrees celsius and weigh several to tens of tons. It is extremely dangerous for humans to visually inspect these steel products in such environments. Therefore, the use of automatic inspection equipment for steel surfaces is essential. Initially, image-processing methods were used, but with recent advances in deep learning, deep-learning-based methods are also being applied in this field. However, the method currently widely used involves utilizing existing models through transfer learning, which inevitably causes curvature of the input image data and limits performance. Furthermore, previous studies have focused on 2D sheet metal products, and there has been no research on three-dimensional geometric products. In this study, we propose dataset generation through geometric transformations that parameterize the structure of the steel surface defect detector hardware, along with a performance-based model optimization algorithm. In validation experiments, an average F1 score of 0.932 and an average area under curve of 0.99 were obtained, implying that the proposed algorithm has near-ideal performance.

Published: July 2024

Abstract

In this work, we explored the impact of indium composition (x) on the structural and optical characteristics of InxAl1-xAs layers within the context of quantum cascade laser (QCL) structures grown on InP (100) substrates using the Metal Organic Vapor Phase Epitaxy (MOVPE) method. The quality of the InxAl1-xAs QCL is notably influenced by the growth with low indium composition, evident in terms of crystallinity, interface sharpness, and optical properties. The properties of the InAsP layer at the InP/ InxAl1-xAs junction are particularly sensitive to the indium composition. A drop below 0.52 in indium composition leads to a substantial lattice mismatch between the InxAl1-xAs layer and the InP substrate, typically exceeding [3 8]%. This mismatch induces defects or traps within the bandgap, significantly impacting carrier localization in this system. Our study demonstrates that cultivating InxAl1-xAs with a low indium concentration results in a strained (lattice-mismatched) InxAl1-xAs layer. This finding is significant as it can be leveraged to balance strain in high indium content InGaAs layers, particularly in the context of applications involving quantum cascade lasers.

Abstract

Background: It is known that unicornuate uterus is a type of Müllerian anomalies and is associated with adverse pregnancy outcomes. However, previous studies on unicornuate uterus were mostly on singleton pregnancies, the perinatal outcomes of twin pregnancies with unicornuate uterus remains elucidating.This research aimed to investigate the perinatal outcomes of twin pregnancies in women with unicornuate uterus.
Methods: A total of 283 women with unicornuate uterus, 21 twin pregnancies (group A), 262 singleton pregnancies (group B) and 105 twin pregnancies with normal uterus (group C) were enrolled who delivered at West China Second University Hospital, Sichuan University from January 2013 to December 2022, general characteristics and perinatal outcomes were retrospectively analyzed.
Results: In twenty-one twins with unicornuate uterus, 20 cases (95.2%) were dichorionic diamniotic twins and 1 case (4.8%) monochorionic diamniotic twin. Seventeen cases (81.0%) were conceived by in vitro fertilization-embryo transfer (IVF-ET) and 4 cases (19.0%) naturally. The mean gestational weeks of delivery were (33.8±5.7) weeks and 19 cases (90.5%) were cesarean section.The twin group (A) was associated with a significantly higher rate of preterm premature rupture of membranes (38.1%,8/21), preterm deliveries (85.7%,18/21) (preterm delivery (PTD) was defined as a birth occurring after 28 weeks and before 37 completed weeks of gestational age), and neonatal intensive care unit (64.3%,27/42) than that of group B and group C (p <0.05). Moreover, the live birth weight in group A (1931.7±535.2)g was lower than in group B and group C (p <0.001).
Conclusions: The incidence of complications and risk of adverse perinatal outcomes in twin pregnancies with unicornuate uterus is higher than that in singleton with unicornuate uterine and twin pregnancies with normal uterine. Thus, maternal and fetal monitoring during pregnancy should be strengthened to achieve good outcomes.
Making plaque assessment easier – a validation study of simplified versions of the Marginal Plaque Index
Authors: Weik Ulrike , Eidenhardt Zdenka , Deinzer Renate 
Published: July 2024

Abstract

Background
The assessment of plaque indices may be time-consuming and error-prone. Simplification of these indices may increase their utility without compromising their validity. The aim of this study was to evaluate the validity of two simplified versions of the Marginal Plaque Index (MPI).
Methods
Two simplified versions of the MPI as well as the Plaque Control Record (PCR) were derived from full-scale MPI assessments in two studies with four age groups (N = 42 10-year-olds; N = 24 15 year-olds; N = 53 university students (18y-33y); N = 66 parents (32y-57y). Correlations with the Turesky modification of the Quigley-Hein Index (TQHI) and the Papillary Bleeding Index (PBI) were calculated.
Results
The indices derived from the MPI showed high convergence with each other (all r ≥ 0.94) and with the TQHI (r ≥ 0.80). The concurrent validity of the MPI with the PBI was equal to that of the TQHI in all age groups. The simplified versions of the MPI and the PCR show a lower convergent validity with the PBI than the MPI within parents (p < 0.05). In the other age groups, their convergent validity was equal to that of the MPI.
Discussion
Simplification of the MPI does not affect its convergent validity with other plaque indices but may reduce its concurrent validity with the PBI in middle-aged adults.
Ultra-low power-consumption OLEDs via phosphor-assisted thermally-activated-delayed-fluorescence-sensitized narrowband emission

Published: July 2024

Abstract

The further success of OLED beyond conventional low-luminance display applications has been hampered by the low power efficiency (PE) at high luminance. Here, we demonstrate the strategic implementation of an exceptionally high-PE, high-luminance OLED using a phosphor-assisted thermally-activated-delayed-fluorescence (TADF)-sensitized narrowband emission. On the basis of a new TADF sensitizing-host possessing a fast reverse intersystem crossing, an anti-aggregation-caused-quenching character and a good bipolar charge-transporting ability, this design achieves not only a 100% exciton radiative consumption with decay times mainly in the sub-microsecond regime to mitigate exciton annihilations for nearly roll-off-free external quantum efficiency, but also narrowband emission with both small energetic loss during energy transfer and resistive loss with increasing luminance. Consequently, besides a maximum PE of 187.7 lm/W, an exceptionally high critical maximum luminance (where a PE of 100 lm/W is maintained) of over 110,000 cd/m2 is achieved for the proof-of-the-concept device, nearly one-of-magnitude higher than the previous record.
Treatment of Hypertension in Children
Authors: Mainieri Francesca , Tagi Veronica Maria , Chiarelli Francesco 
Published: July 2024

:
Hypertension is a real problem in children. It shows a tracking behaviour, representing
a key risk factor for hypertension, cardiovascular disease, and end-organ failure in adulthood.
However, the importance of addressing arterial hypertension in children is not limited to its risk of
tracking into adulthood. Thus, early detection and management are crucial. Hypertension may be
primary or due to secondary causes, and identification of this distinction is very important for the
treatment setting. Importantly, the management of hypertension in children is crucial to prevent
the well-known cardiovascular effects in adulthood. As demonstrated in the literature, healthy eating
habits, together with regular physical activity, can have a major impact on reducing high blood
pressure and preventing organ damage in children and adolescents. However, suppose these are
not sufficient to treat hypertension. In that case, if patients are symptomatic and/or have additional
metabolic conditions such as obesity, type diabetes mellitus, or chronic kidney disease, anti-hypertensive
medication must be started. Recent guidelines have provided clear guidance on the treatment
of hypertension and hypertensive crisis in pediatric age. On the other hand, there are currently
few specific recommendations on the treatment of isolated nocturnal hypertension and treatment-
resistant hypertension. This review aims to summarize the most recent recommendations for the
treatment of hypertension and hypertensive crisis in children and the last years' knowledge and experience
in treating childhood isolated nocturnal hypertension and resistant hypertension of childhood.

Authors: Tursi Antonio , Mocci Giammarco , Usai Satta Paolo , Elisei Walter 
Published: July 2024

Background:
Microbial imbalance is thought to play a role in the pathogenesis of Diverticular
Disease (DD).

Objective:
We aimed to assess the efficacy of a symbiotic mixture (Prolactis GG Plus®) in the
treatment of moderate to severe DD, scored according to the Diverticular Inflammation and Complication
Assessment (DICA) classification.

Methods:
A retrospective study was conducted enrolling the following patients: at the first diagnosis
of DD; in whom DD was diagnosed with colonoscopy and scored according to DICA classification;
treated with Prolactis GG Plus® two times/daily for 2 consecutive months; in whom the
severity of the abdominal pain was scored with a 10-points visual-analogue scale (VAS) at baseline
and the end of follow-up; in whom fecal calprotectin (FC) was assessed at baseline and the
end of follow-up as μg/g.

Results:
Twenty-four patients were identified (10 males, 14 females; 16 as DICA 2, and 8 as DICA
3). Prolactis GG Plus® decreased the severity of abdominal pain both in DICA 2 (p =0.02)
and DICA 3 patients (p =0.01), while FC decreased significantly in DICA 2 (p <0.02) but not in
DICA 3 (p =0.123) patients. Acute diverticulitis occurred during the follow-up in two DICA 3 patients
but none DICA 2 patients. Add-on therapy was required by eight DICA 2 (50%) and six DICA
3 patients (75%).

Conclusion:
In newly diagnosed patients with DD, the symbiotic mixture Prolactis GG Plus® can
be a potential treatment for moderate (DICA 2) DD as a single treatment.
Structural and semantic features of ethno-stereotyping of space-time relations in different linguistic cultures
Authors: Maremukova E. V. 
Published: July 2024

Purpose of research. The article is aimed at determining the features of the linguistic fixation of space-time relations in languages with different structures, identifying unique characteristics that form an integral part of the culture of the people, the specifics of the national mentality represented in the language. Based on the material of differently structured Kabardian-Circassian, Russian and English languages terms of space and time are analyzed in a comparative aspect.Methods. The use of a complex of general scientific and linguistic methods, including methods of comparative, lexical-semantic, etymological and conceptual analysis, made it possible to identify the features of linguistic objectification of ethnocultural information in the languages under study, to explore the features of national thinking in the process of linguistic projection of culturally significant information, to establish differences in the perception and interpretations of details of the surrounding world by different peoples, as well as the role of language in the formation of national and cultural identity.The results of the study revealed linguocultural differences in the perception and linguistic objectification of time among different peoples, in particular, structural and semantic features of fixation of temporal concepts in the language, as well as the projection of the use of a certain referential system in the language and at the cognitive level. The introduction of new language material into scientific use promotes further research in linguoculturology, since, as noted by many researchers, not a single linguoculture is capable of providing comprehensive information.Conclusion. A comparative analysis of the spatial coding strategies used (absolute and relative systems of reference) reveals the representation in the native language of the way of thinking of its speakers, as well as the influence of language on the perception of the surrounding world. The temporal categorization of reality explicates the peculiarities of national worldview. The presence in a language of a large number of time-specifying details can be seen as an indicator of the meaning that an ethnic community attaches to time.
Linguophilosophical and sociolinguistic analysis of the french words “Globalisation” and “Mondialisation” in relation to the concept of globalization
Authors: Andreeva O. А. 
Published: July 2024

Purpose of research is to study the semantics of the French words “globalisation” and “mondialisation” in the socio-historical context of the phenomenon of globalisation. The origin of the phenomenon of globalization is considered and its multidimensional nature in the context of global processes is revealed.Methods. The research uses the method of contextual, hermeneutic, historical and logical analysis of theoretical activities and practical developments on the topic. It is based on a linguophilosophical approach to the consideration of the phenomenon of globalization, taking into account the differences between human society following the path of formation of consciousness and civilization. Theoretical developments of domestic and foreign researchers in the field of philosophy, sociology, linguistics, and history are taken into account when solving the tasks set.Results. The article presents the main stages of the emergence of the phenomenon of globalization in the course of the socio-historical development of human civilization. It is determined that the phenomenon of globalization affects many aspects: economic, political, cultural, military, environmental. The meanings of the French words "globalisation" and "mondialisation", denoting the concept of globalization, are considered, and the specific features of the processes designated by them are revealed. It is established that "Mondialization" geographically covers the designated areas, and "globalization" is a continuation of the process of "mondialization" by creating global systems in the field of production and digitalization.Conclusion. Ultimately, it is determined that the words "globalisation" and "mondialisation", which denote the concept of globalization in French scientific thought and are often used synonymously, in practice imply different, albeit interrelated, processes. The French word "mondialisation", meaning "globalization", comes from the word "monde" - "world" and means a multidimensional process affecting various aspects of the life of societies and individuals, associated with geographical expansion. "Globalisation" does not refer to a view of the world, but to liberation from national frameworks.
Gender Psychological Characteristics in Phraseology: Dynamics of Meanings in the Newspaper Corpus
Authors: Bespalova E. A. 
Published: July 2024

Purpose of research is to describe the features of the functioning of phraseological phrases in media texts containing a gender-marked component and belonging to a group of psychological characteristics, in order to accumulate data on the specifics of operating with phraseological meaning and its development in the speech of modern native speakers of the Russian language.Methods. To achieve this goal, the methods of observation of linguistic material, continuous sampling, lexico-graphic, lexico-semantic and contextual analysis, classification, and systematization of data were used.Results of the analysis indicate that the phraseological resources of the language are more often used by the authors of media texts to nominate and positively evaluate the volitional qualities of men and women, as well as scholarship and high moral qualities of men; phraseological designations of indecision and unpreparedness for the practical life of women and lack of independence and greed of men bear a negative connotation. At the same time, the perception of the stereotype of bravery and dedication of a Russian woman as a positive necessary quality is changing: entering burning huts is no longer tempting.Conclusion. The popularity of the most frequent phraseology "iron lady" is due to its media etymology and interest in the person of Margaret Thatcher, whose style of behavior gives rise to associations among the authors of media texts with modern women politicians and prominent representatives of other fields of activity. The trends in the functioning of the units of the analyzed group in the media language include the actualization of the meanings of individual components of phraseological turnover, the structural and meaningful transformation of combinations, the development of meanings up to the antonymous, the creation of a language game and anecdote. Examples of changes in the gender attribution of phraseology are noted.
