Published: June 2024

Introdução: A secagem desempenha um papel crucial no beneficiamento da madeira, reduzindo riscos de perdas por defeitos e biodeterioração. O objetivo deste estudo foi realizar o monitoramento do teor de umidade das madeiras de Couratari oblongifolia (imbirema) e Diplotropis purpurea (sucupira), submetida ao processo de secagem ao ar livre no município de Rolim de Moura, RO. Metodologia: As peças de 35 cm foram monitoradas durante a secagem ao ar livre, e amostras de 5 cm foram em estufa a 103±5°C até a obtenção de massa constante. Resultados: A madeira submetida a secagem na estufa apresentou os valores de umidade a base úmida (Ubu) da madeira de Imbirema (33,66%) e a Ubs (50,73%). Para a espécie da madeira Sucupira, apresentou um valor de Ubu de (49,05%), e para Ubs foi de (96,30%), respectivamente. Os teores de umidades iniciais para as espécies do estudo apresentaram valores distintos. Para Imbirema foram de 50,73% para ambas as amostras, sendo que para a espécie de Sucupira foram de 96,30% a 71,88%. Discussão: As espécies tiveram um alto nível de perda de umidade durante os primeiros dias, até chegarem em 36% de umidade, logo apresentaram uma fase estável, até chegar a uma umidade próxima ao ponto de saturação das fibras. As distintas taxas de perda entre as espécies indicam variação no comportamento de secagem. Conclusão: Essa análise reforça a influência dinâmica e multifatorial na secagem ao ar livre, enfatizando a necessidade de métodos de monitoramento adequados para compreender e otimizar o processo de secagem da madeira

Authors: Silva Gisele Ruiz , Henning Paula Corrêa
Published: June 2024

O artigo tem como objetivo analisar alguns traçados históricos e filosóficos que dão sustentação às práticas educativas desenvolvidas com crianças de 4 e 5 anos matriculadas em classes de educação infantil na atualidade. Toma como corpus analítico as estratégias metodológicas relatadas por professoras na Revista Pátio Educação Infantil no período de 2014 a 2018. Assume a perspectiva dos estudos foucaultianos e inspira-se na história efetiva para traçar uma breve história genealógica a respeito do pensamento pedagógico moderno, a fim de encontrar algumas pistas sobre a composição das forças que nos ensinaram as formas como realizamos nossas práticas de educação infantil hoje. Desse modo, revisita ditos de Jan Amos Comenius e Jean Jacques Rousseau, pensadores clássicos da Pedagogia Moderna, apontando-os como instauradores de discursividade sobre os modos como assumimos o pensamento pedagógico contemporâneo. Busca dar visibilidade às práticas atuais no que se refere à Educação Infantil e trata de compreender como estas foram se engendrando e se constituindo ao longo da história da Pedagogia levando à emergência de uma arte pedagógica da atualidade, a qual é entendida como uma atualização dos princípios da arte de ensinar comeniana e da arte de educar rousseauniana.

Causal relationships between immunophenotypes, plasma metabolites, and pancreatic cancer: a mediation Mendelian randomization study
Authors: Liu Jiawei , Zhou Jian , Bie Hongyu , Li Xin , Yan Cihui , Ran Xiubao
Published: June 2024

Background: Current research exploring the interconnections
between Immune cell phenotype, plasma metabolites, and the risk of
pancreatic cancer remains scant. Further investigation is necessary to
understand the complex interactions involved. Methods:
Instrumental variables for 731 immune phenotypes (N = 3,757), 1,400
circulating metabolites (N = 8,299), and pancreatic cancer (N = 1,196)
were obtained from a meta-analysis of genome-wide association studies
(GWAS). A two-step, two-sample Mendelian randomization study using the
IVW method was conducted to investigate the causal influence of immune
cell phenotypes on pancreatic cancer and to assess the intermediary role
of circulating metabolites within this context. Sensitivity analyses
were performed to test the robustness of the results, potential
heterogeneity, and pleiotropy. Results: Mendelian randomization
analyses identified protective effects of CD64 on monocyte (OR = 0.859,
95% CI 0.802-0.920, P = 1.65 × 10 ,
P = 0.012) against pancreatic cancer.
Additionally, 68 metabolites were suggestively associated with
pancreatic cancer. Notably, mediation MR revealed that the causal role
of CD64 on monocytes in pancreatic cancer was largely mediated by
1-palmitoleoylglycerol (16:1) level (OR = 0.0089, 95% CI
0.00121-0.0167, P = 0.023), accounting for 5.91% of the total
effect. Conclusion: There is a causal relationship between CD64
on monocytes and pancreatic cancer, which may be related to mediation by
circulating metabolites. This study enhances our understanding of the
interplay between immune responses and the risk of pancreatic cancer,
offering valuable insights for the development of immune-oriented
therapeutic strategies.

Authors: Gupta Pralok , Das Sanchita Basu , Sharma Saarthak , Domingo Ma. Veronica
Published: June 2024

This paper analyzes tourist inflows as a determinant of merchandise exports for the Pacific and finds that inbound tourism to Pacific developing member countries significantly increases merchandise exports from these economies. Exports are further boosted if international tourists come from countries with which Pacific developing member countries have a shared language, formed an economic partnership through free trade agreements, and have easy visa policies. The paper recommends that inbound tourism to the Pacific is leveraged to diversify economic activities and develop industries, such as garments or souvenir-related manufacturing.

Authors: Jang Shin Yi , Seo Su Ra , Kim Seong Kyong , Kim Kyeongsug
Published: June 2024

Purpose: Few studies have assessed the prevalence of temporomandibular disorders (TMD) in the Korean population.Methods: We used cohort data from the Korean National Health Insurance Service between 2012 and 2020. The data consisted of main diagnoses related to TMD (International Classification of Diseases 10th Revision [ICD-10] code: K07.6 and K07.6x). The age-standardized prevalence of TMD was calculated using the estimated Korean population in 2020 as a reference.Results: The age-standardized prevalence of TMD increased from 604 persons per 100,000 persons in 2012 to 869 persons in 2020. In 2020, the overall age-standardized prevalence was 1,355 persons in the 10 to 19 years age group, 1,809 persons in the 20 to 29 years age group, and 979 persons in the 30 to 39 years age group. The age-standardized prevalence was approximately 1.5 times higher in females than in males (698 persons in males vs. 1,040 persons in females). Among the specific TMD subtypes, the age-standardized prevalence of internal derangement of the temporomandibular joint and pain in the temporomandibular joint, not classified elsewhere, was higher than that of other specific TMDs.Conclusion: The overall age-standardized prevalence of TMD was higher in the 10s, 20s, and 30s age groups and in females between 2012 and 2020. The age-standardized prevalence of internal derangement of temporomandibular joint was the highest among specific TMD subtypes.

Published: June 2024

The present study was conducted from June–July, 2021 in online mode and a questionnaire was designed at the Department of Food Science and Nutrition, College of Community Science, G. B. Pant University of Agriculture and Technology, Pantnagar. The study aims to find an association of perceived stress with socio-demographic factors, health profile and physical activity among Indian adults during the second wave of COVID-19. Data on perceived stress was collected through an online cross-sectional survey of 1933 Indian adults based on the Perceived Stress Scale (PSS). Multivariate ordinal regression was conducted to identify the predictors of perceived stress. Indian adults were moderately stressed, with a mean PSS score of 19.7±5.5 during the crisis time of COVID-19. The study population remained moderately active (59.3%) during the lockdown period. Perceived stress was negatively associated with age, education, income, and physical activity and positively associated with random blood sugar levels and sitting time. Odds of perceived stress increased with female gender, separated marital status, having one child or adolescent in the family, graduate or postgraduate as the educational status of the family’s head, and increased sitting time. High educational status, retirement, regular employment, middle or lower-class social class, and high physical activity level were negative predictors of perceived stress. The current investigation highlights the role of multiple factors in the perception of stress and the need for tailored interventions for vulnerable groups focusing on education and physical activity.

The experiment was conducted during January, 2022 to January, 2023 at the Department of Animal Genetics & Breeding, College of Veterinary Science and Animal Husbandry, Kamdhenu University, Navsari, Gujarat, India to identify polymorphisms in HSP 70 gene. Heat Shock Proteins (HSPs) known as molecular chaperones are essential for cells’ ability to recover from stress and serve as the primary defence mechanism within cells. They are extremely conserved and essential to the response to heat stress and cellular thermotolerance. Even though there are numerous HSP genes, in livestock species, heat tolerance is primarily associated with HSP 70. This gene polymorphisms have been linked to heat tolerance, milk production, fertility and cattle susceptibility to disease. They can be utilised as genetic markers to help choose animals that are more resilient to climate change, have stronger immune systems and perform better overall. A 220 bp fragment of bovine HSP 70 gene was subjected to Polymerase Chain Reaction- Single-Strand Conformation Polymorphism (PCR-SSCP) technique to identify the polymorphism. PCR-SSCP pattern was associated with the thermotolerance traits in Kankrej cattle using the univariate GLM model of SPSS 26. HSP 70 gene (220 bp fragment) was found to be monomorphic documented on SSCP gel which revealed only one genotype (AA) in all Kankrej cattle. It is concluded that genotype and its association with thermotolerance traits were found to be non-significant. However, The HSP 70 polymorphism is expected to strongly predict cattle heat tolerance, aiding in selection for thermotolerance.

The manufacturing industry plays a central role in the economies of developing countries, including Indonesia. Financial performance significantly impacts the assessment of a company's value. This research aims to analyze and gain a deeper understanding of how the gender, age, and educational level of Chief Executive Officers (CEOs) influence the performance of companies listed in the industrial sector on the Indonesia Stock Exchange (IDX). The characteristics of the study's population include companies in the industrial sector listed on the main board and development board of the IDX, which have published annual reports during the period 2012-2022. The data analysis methods employed involve pooled ordinary least squares and quantile regression. The Hannan-Quinn criteria are utilized to select the best equations for interpretation of the hypothesis testing results. Equations using quantile regression are selected for hypothesis testing. From the hypothesis testing results in this study, it can be concluded that the gender of the CEO has an impact on company performance, while the age and educational level of the CEO do not affect company performance. A negative trend is identified, where male CEOs tend to have a lower impact on company performance compared to their female counterparts in the CEO position.

Published: June 2024

OBJECTIVE

Evaluate whether total elbow replacement (TER) through a lateral approach is accurate and stable.

ANIMALS

12 skeletally mature large-breed dog cadavers were used.

METHODS

Limb alignment, elbow joint motion, and collateral ligament laxity were evaluated preoperatively. The order of surgery (left or right) and the approach (lateral or medial) were randomly selected for TER in each dog. The other approach was used in the contralateral elbow. Intraoperative technical difficulties, duration of surgery, and anatomic complications were recorded. Limb alignment, elbow joint motion, collateral ligament laxity, and prosthetic component alignment were evaluated after surgery. Data were collected from June 11 to 15, 2023.

RESULTS

The duration of surgery using a lateral or medial approach did not differ (P = .499). Anatomic complications were not observed. The lateral approach resulted in 8° more elbow extension (P = .003), 1.58° less lateral collateral ligament constraint (P = .033), 2.80° less medial collateral ligament constraint (P = .002), 4.38° less frontal plane constraint (P = .004), 8° greater humeral component inclination (P = .033), and 5.6° greater radioulnar component varus (P = .001) than the medial approach. Varus of the radius, mechanical axis deviation, limb supination, elbow flexion, mediolateral humeral component and craniocaudal radioulnar component orientation did not differ among joints operated using a lateral or medial approach. In normal cadaveric elbows, a lateral approach for TER appears feasible, producing equivalent limb alignment, joint laxity, and joint motion to normal elbows and to TER placed using a medial approach.

CLINICAL RELEVANCE

In dogs, TER can be performed using a lateral surgical approach.
An Approach to Hopfield Network-Based Energy-Efficient RFID Network Planning
Authors: Hoa Le Van , Tung Nguyen Van , Nhat Vo Viet Minh
Published: June 2024

Radio Frequency IDentification (RFID) Network Planning (RNP) is the problem of placing RFID readers in a working area where a tag is interrogated by at least one reader and at the same time satisfies some constraints such as minimum number of placed readers, minimal interference, and minimal outside coverage. The RNP optimization has been proven NP-hard; thus, natural-inspired approaches are often used to find the optimal solution. The paper proposes an energy-efficient RNP approach in which the positions of placed readers are optimized by a Hopfield network, and the energy efficiency is achieved through a placement area restriction technique. A mechanism of redundant reader elimination is also added to minimize the number of placed readers. Simulation results show that the Hopfield network-based energy-efficient RNP approach achieves the maximum tag coverage and energy efficiency by reducing interference, outside coverage, and the number of placed readers.

Authors: Gaftandzhieva Silvia , Doneva Rositsa , Bliznakov Milen
Published: June 2024

Despite the wide acceptance of blended learning in Higher Education Institutions (HEIs) worldwide, the issue of monitoring its implementation has been little addressed in the literature. The paper presents the results of the first stage of the study for the development and implementation of tools for monitoring the degree of use of blended learning courses within the learning process in HEIs. The tool introduced here extracts data from the database of the e-learning environment and visualizes the results of the data analysis in dashboards that provide valuable insights to decision-making for improving the quality of blended learning implementation. The tool allows governing bodies to track trends in the user registration, development, and updating of blended learning courses, the number of learners, and the usability of the courses by users for a selected period. Based on the results of tool experimental testing, goals for its further development are set.
African Vulture Optimization-Based Decision Tree (AVO-DT): An Innovative Method for Malware Identification and Evaluation through the Application of Meta-Heuristic Optimization Algorithm
Authors: Kaithal Praveen Kumar , Sharma Varsha
Published: June 2024

Malware remains a big threat to cyber security, calling for machine learning-based malware detection. Malware variations exhibit common behavioral patterns indicative of their source and intended use to enhance the existing framework’s usefulness. Here we present a novel model, i.e., African Vulture Optimization-based Decision Tree (AVO-DT) to increase the overall optimization.

The datasets from Android apps and malware software train the AVO-DT model. After training, the datasets are pre-processed by removing training errors. The DT algorithm is used by the developed AVO model to carry out the detection procedure and predict malware activity. To detect malware activities and improve accuracy, such an AVO-DT model technique employs both static and dynamic methodologies. The other measurements on Android applications might be either malicious or benign. Here we also developed malware prevention and detection systems to address ambiguous search spaces in multidimensionality difficulties and resolve optimization challenges.
Complementarity-Determining Region 3 (CDR3) of the Heavy Chain Only Antibodies: Therapeutic Perspectives
Authors: Talpašová Lea , Bhide Katarína , Maľarik Tomáš , Bhide Mangesh
Published: June 2024

Neuroinfections are difficult and time-consuming to treat. The main bottleneck in therapy is drugs’ inability to enter the central nervous system (CNS) via the blood-brain barrier (BBB). Because the diffusion of conventional antibodies in tissues is limited by their large size (150 kDa), it is necessary to find an antibody fragment that can cross the BBB and treat CNS infections. Camelid heavy chain only antibodies, also known as nanobodies, possess a unique Variable domain of a Heavy chain (VHH). The VHH could be used as an alternative to conventional antibodies and have enormous potential in a wide range of medical and bio-technology fields. The VHH with an average molecular weight of 15 kDa can diffuse nearly four times better in tissues and tumours than common antibodies. A VHH is made up of four framework regions (FR1‒4) and three hypervariable complementarity-determining regions (CDR1‒3), with CDR3 being particularly important in interaction with pathogen epitopes. Experimental results have shown that the CDR3 domain alone can bind to epitopes and may contribute to reduce the size of the antigen-recognizing molecule, allowing it to be used more effectively to diffuse much better in tissues, and as well as to cross the BBB and biodistributed in CNS.

Authors: Benedetti T. , Weiland J. E. , Zasada I. A.
Published: June 2024

Oregon leads the United States in nursery production of shade trees and is third in deciduous and broadleaf evergreen shrub production. Plant-parasitic nematodes have been implicated in problems with the growth of plants in nurseries and are also of phytosanitary risk. A greenhouse experiment was conducted to evaluate the host status of four trees (Quercus alba, Quercus garryana, Acer campestre, Thuja occidentalis) and two shrubs (Buxus sempervirens, Rhododendron catawbiense) to Meloidogyne incognita, Meloidogyne hapla, and Pratylenchus neglectus. Each plant/nematode treatment was replicated five times, and the experiment was conducted twice. Plants were inoculated with 3,000 eggs of M. incognita or M. hapla and 2,500 individuals of P. neglectus two weeks after planting. After three months, the plants were harvested, and the total density of nematodes in soil and roots for P. neglectus and the total density of second-stage juveniles (J2) in soil and eggs on roots for M. hapla and M. incognita were determined. The final nematode population (Pf) and reproductive factor (RF = Pf/initial population density) were calculated. For M. incognita and M. hapla, all of the ornamental trees and shrubs would be considered as fair to good hosts with RF values > 1. Meloidogyne incognita had the highest Pf (5,234 total J2 and eggs/pot) and RF value (28.4) on A. campestre. For P. neglectus, all of the ornamental trees and shrubs were fair to good hosts, except for B. sempervirens. Buxus sermpervirens was not a host for P. neglectus, with an RF value of almost 0. This is the first report of Q. alba, Q. garryana, and A. campestre as hosts for M. incognita, M. hapla, and P. penetrans. This is also the first report of T. occidentalis and R. catawbiense as hosts for P. penetrans and the non-host status of B. sermpervirens for P. penetrans.
Blackmail, Unproductive Exchanges, Fraud, and the Libertarian Theory of Voluntariness
Authors: Wysocki Igor
Published: June 2024

The main purpose of this paper is to rationally reconstruct Nozick’s account of unproductivity, especially vis-à-vis his characteristically libertarian, and hence uncompromising, ban on fraud. We posit that, when Nozick’s theory is interpreted charitably, it does not yield to contradictory prescriptions concerning permissibility. That is, there does not have to be any inconsistency in the Nozickian ban on certain exchanges, with the ban tracking two properties of the said exchanges; that is, either (1) their unproductivity or (2) their fraudulence. When analyzing economic exchanges, our interest is focused on both productive and unproductive blackmail exchanges. However, we suggest that Nozick’s banning exchanges along the lines of their unproductivity tallies poorly with his avowed libertarianism since his position predicts prohibiting unproductive and yet non-fraudulent exchanges. Hence, and we suggest resolving the said tension in a principled libertarian (deontological) manner; that is, by banning fraudulent exchanges and allowing non-fraudulent ones, ceteris paribus, while submitting that the properties of exchanges such that being productive or being unproductive are morally inert.
The Economic and Energy Impact of Slow Orders in Slovakia on Railway Operators
Authors: Daněček Matěj
Published: June 2024

This paper looks at the current state of the railways in Slovakia and the economic losses which result from trains passing through locations with an increased incidence of sections of line with slow orders imposed. A calculation of time and financial losses due to a high number of slow order sections will be performed. We shall also focus in more detail on the development and related financing of Railways of the Slovak Republic (ŽSR) and make a number of comparisons with some neighbouring countries. Attention will also be paid to the actual status of completed and unrealised projects in the most recent period, exploring the reasons behind project delays and cancellations. The paper will also calculate how individual train journeys along slow order sections translate into actual operation. The actual impacts on railway operators will also be examined in terms of economics, time, and energy, with an emphasis on the sustainability of current practices and potential areas for improvement.
Political Philosophy of “The Tale of Igor’s Campaign”
Authors: Fenenko A. V.
Published: June 2024

The political, philosophical and conceptual basis of “The Tale of Igor’s Campaign,” a conventionally ancient Russian poem about the unsuccessful campaign of the Novgorod-Seversk prince Igor Svyatoslavich (1155-1201) against the Polovtsians in 1185, remains debatable. It directly depends on the author’s intention in the context of the intended dating of the era. From a scientific point of view, it is more correct to talk not about the political and philosophical thought of “The Tale...”, but rather about the complex of discussions around this text. Therefore, it is possible to understand the political motives of “The Tale...” only in the context of the controversy surrounding its dating, which has been going on for more than two centuries. The article presents discussions about the authenticity of the text, its relationship with other ancient Russian sources, the historiography of disputes about the text, and conclusions regarding its political philosophy.

Objectives: To analyze the patient profile and characterize the oral health status, oral habits, and daily oral hygiene difficulties of individuals with rare diseases. Methods: Data were collected from records of the clinic for people with disabilities at the Faculdade de Medicina Dentária da Universidade de Lisboa, using the Decayed, Missing, and Filled Teeth index, the simplified debris index, and the bleeding index. Results: The sample comprised 64 individuals with 33 different rare diseases, with a mean age of 31.5(±10.29) years, predominantly male (54.7%). Most could move without difficulty (51.6%), required assistance in activities of daily living (60.9%), and were cooperative in oral hygiene (54.7%). Also, 40.6% could not communicate. Half of the sample brushed their teeth twice a day, with 18.8% being independent in this activity, and the most common toothbrushing difficulty was not being able to rinse (53.1%). The Decayed, Missing, and Filled Teeth index was 8.81 (±7.54), with a higher number of filled teeth (4.47; ±5.35). The bleeding index had a mean of 1.23 (±0.56), and the simplified debris index had a mean value of 1.62 (±0.78). Conclusions: The population studied expresses care for oral health and treatment.
Non-granulomatous Morbihan disease: a case report
Authors: AlFadil Sara , Alfalah Renad , Alhumaid Ahmed , Sonbol Haitham
Published: June 2024

Background: Morbihan disease (MD) is a rare dermatological condition, which is characterized by rosaceous lymphedema or erythematous edema of the middle and upper thirds of the face. To date, the underlying pathogenetic mechanisms of MD remains unclear. Although MD is considered a late-stage manifestation of rosacea, it has been reported to exist as an initial presentation, in the absence of other features of rosacea.
Case Presentation: A 27-year-old female with a history of hypothyroidism, presented with a chronic solid, persistent, facial swelling for 4 years without rosacea symptoms. The patient wore a face cover for religious and social reasons, and therefore her face was not exposed to direct sunlight. Based on the clinical findings, a preemptive diagnosis of MD was established, and the patient was started on oral Isotretinoin with significant improvement. Histopathology of the left cheek revealed perifollicular lymphocyte and histocyte infiltration and mild dermal fibrosis; no granuloma or malignancy was found. After 36 months of treatment, there was an overall 65%-70% improvement since the initial visit and the patient was pleased with her results.
Conclusion: In contrast to published reports, the formation of epithelioid cell granuloma as well as mast cell infiltration were not observed in presented case. The diverse histopathological features of MD are most likely attributed to its varying underlying inflammatory triggers. The presence of MD without rosacea features supports the argument that MD represents a separate disease process.

Authors: Ntsanwisi Samuel , Simelane-Mnisi Sibongile
Published: June 2024

This study has investigated teachers' perspectives on enhancing entrepreneurial education in South African primary and secondary schools in the Limpopo Province. It has been motivated by a gap in the literature that indicated further research was needed. A sample of 101 teachers from rural and township schools employed a quantitative method. Data were collected using a Teachers’ Attitudes Towards Entrepreneurship Education questionnaire focusing on the importance of entrepreneurship education within a school context. They were analysed using the Statistical Package for the Social Sciences version 25. The study demonstrated a solid Cronbach alpha reliability score of 0.90 with satisfactory face validity. The results showed that teachers expressed a need for time, training, financial resources, physical resources for classroom use, networking opportunities and sharing best practices to successfully implement entrepreneurship education in schools. It is recommended that entrepreneurship be taught as an individual subject in schools to yield entrepreneurial-minded learners from a young age who will be innovative thinkers, problem solvers, and business-minded.

The European Union’s Deforestation-free Supply Chains Regulations: Opportunities and Challenges for Vietnamese Coffee
Authors: Dang Mai Hai
Published: June 2024

The European Union (EU) adopted the regulation on deforestation-free supply chains (EUDR) in 2023 to reduce the EU market's impact on deforestation and forest degradation worldwide and protect human rights. This regulation provides for a mandatory due diligence mechanism for the supply chain, anchored on total traceability of the chain, with the purpose of ensuring that the products (cocoa, coffee, beef, timber, palm oil, soybeans) traded or exported to the EU are deforestation-free and produced in accordance with conventions that ensure human rights. EUDR will have a significant impact on Vietnam's strategic commodity exports, particularly rubber, cocoa, and coffee. This research aims to identify and analyze the impact of EUDR towards Vietnam coffee exports. The research techniques employed are the common qualitative techniques, such as descriptive research, observation, document analysis, inferencing, categorization, systematization, and generalization.

Semiglobal Exponential Stability for Dual-Quaternion-Based Rigid-Body Tracking Control
Authors: Zinage Vrushabh , Ram S. P. Arjun , Akella Maruthi R. , Bakolas Efstathios
Published: June 2024

Semi-Global Exponential Stability (SGES) is proven for the combined attitude and position rigid-body motion tracking problem, presenting a significant upgrade compared to previously proposed controllers which can only guarantee asymptotic stability. Dual quaternions are used to jointly represent the rotational and translational tracking error dynamics of the rigid body. A novel nonlinear feedback tracking controller is proposed, and a Lyapunov-based analysis is provided to prove SGES of the closed-loop dynamics. The analysis does not place any restrictions on the reference trajectory or the feedback gains. This stronger SGES result aids in further analyzing the robustness of the rigid-body system by establishing input-to-state stability (ISS) in the presence of time-varying additive and bounded external disturbances. Motivated by the fact that, in many aerospace applications, stringent adherence to safety constraints such as approach path and input constraints is critical for overall mission success, a framework for safe control of spacecraft is presented that combines the proposed feedback controller with control barrier functions. Numerical simulations are provided to verify the SGES and ISS results and also showcase the efficacy of the proposed nonlinear feedback controller in several nontrivial scenarios, including trajectory tracking, transposition and docking, flip maneuvers, collision avoidance, and rendezvous.
