Using the LSTM Neural Network and the UWB Positioning System to Predict the Position of Low and High Speed Moving Objects
Authors: Paszek Krzysztof , Grzechca Damian
Published: October 2023

Automation of transportation will play a crucial role in the future when people driving vehicles will be replaced by autonomous systems. Currently, the positioning systems are not used alone but are combined in order to create cooperative positioning systems. The ultra-wideband (UWB) system is an excellent alternative to the global positioning system (GPS) in a limited area but has some drawbacks. Despite many advantages of various object positioning systems, none is free from the problem of object displacement during measurement (data acquisition), which affects positioning accuracy. In addition, temporarily missing data from the absolute positioning system can lead to dangerous situations. Moreover, data pre-processing is unavoidable and takes some time, affecting additionally the object’s displacement in relation to its previous position and its starting point of the new positioning process. So, the prediction of the position of an object is necessary to minimize the time when the position is unknown or out of date, especially when the object is moving at high speed and the position update rate is low. This article proposes using the long short-term memory (LSTM) artificial neural network to predict objects’ positions based on historical data from the UWB system and inertial navigation. The proposed solution creates a reliable positioning system that predicts 10 positions of low and high-speed moving objects with an error below 10 cm. Position prediction allows detection of possible collisions—the intersection of the trajectories of moving objects.

Published: October 2023

With advances in the technology applied to automated driving systems (ADSs), active efforts have been made to evaluate the safety of ADS in various complex situations using simulations. In accordance with these efforts, numerous institutions have developed single-scenario pools that reflect a variety of road and traffic characteristics and ADS performances. However, a single scenario has limitations in comprehensively evaluating the performance of complex ADS. Therefore, this study proposed a methodology that combines and transforms single scenarios into multiple scenarios. This aided in continuously evaluating the ADS performance over entire road segments and implemented this methodology in the simulations.
Assessment of Number of Critical Satellites for Ground-Based Augmentation System Continuity Allocation to Support Category II/III Precision Approaches
Authors: Song Junesol , Milner Carl
Published: October 2023

The ground-based augmentation system (GBAS) is a regional system supporting navigation and ensuring the integrity of aircraft near airports during precision approaches. Standardized at the international level, GBAS Approach Service Types (GASTs) C and D, which are defined for the GPS L1 signal, support CAT I and II/III precision approaches with decision heights of 200 and 50 ft, respectively. However, the future GBAS, GAST E, which utilizes dual-frequency and multi-constellation signals, and the GAST D1, defined for both GPS L1 and Galileo E1 signals, require the establishment of standards. To define the continuity requirement, the number of critical satellites must be considered. Currently, there is a lack of analysis on the number of critical satellites for various GBAS service types available to the public. This paper aims to evaluate the number of critical satellites for future GBAS service types, employing optimized GPS and Galileo constellations and assessing all potential protection levels worldwide. The methodology to model the difference of position solutions using the 30 s and 100 s smoothing filters is presented in detail to compute the protection level for GASTs D and D1. The resulting number of critical satellites can be used to define the continuity allocation of future GBAS.

Published: October 2023

Machine learning-based gait systems facilitate the real-time control of gait assistive technologies in neurological conditions. Improving such systems needs the identification of kinematic signals from inertial measurement unit wearables (IMUs) that are robust across different walking conditions without extensive data processing. We quantify changes in two kinematic signals, acceleration and angular velocity, from IMUs worn on the frontal plane of bilateral shanks and thighs in 30 adolescents (8–18 years) on a treadmills and outdoor overground walking at three different speeds (self-selected, slow, and fast). Primary curve-based analyses included similarity analyses such as cosine, Euclidean distance, Poincare analysis, and a newly defined bilateral symmetry dissimilarity test (BSDT). Analysis indicated that superior–inferior shank acceleration (SI shank Acc) and medial–lateral shank angular velocity (ML shank AV) demonstrated no differences to the control signal in BSDT, indicating the least variability across the different walking conditions. Both SI shank Acc and ML shank AV were also robust in Poincare analysis. Secondary parameter-based similarity analyses with conventional spatiotemporal gait parameters were also performed. This normative dataset of walking reports raw signal kinematics that demonstrate the least to most variability in switching between treadmill and outdoor walking to help guide future machine learning models to assist gait in pediatric neurological conditions.
Walking-Speed-Adaptive Gait Phase Estimation for Wearable Robots
Authors: Choi Sanguk , Ko Chanyoung , Kong Kyoungchul
Published: October 2023

This paper introduces a Gait Phase Estimation Module (GPEM) and its real-time algorithm designed to estimate gait phases continuously and monotonically across a range of walking speeds and accelerations/decelerations. To address the challenges of real-world applications, we propose a speed-adaptive online gait phase estimation algorithm, which enables precise estimation of gait phases during both constant speed locomotion and dynamic speed changes. Experimental verification demonstrates that the proposed method offers smooth, continuous, and repetitive gait phase estimation when compared to conventional approaches such as the phase portrait method and time-based estimation. The proposed method achieved a 48% reduction in gait phase deviation compared to time-based estimation and a 48.29% reduction compared to the phase portrait method. The proposed algorithm is integrated within the GPEM, allowing for its versatile application in controlling gait assistive robots without incurring additional computational burden. The results of this study contribute to the development of robust and efficient gait phase estimation techniques for various robotic applications.

Direct Observation of Transient Flow Kinematics of Environment-Friendly Silica-Based Alcogel at Instantaneous Gelation
Authors: Kurumada Kenichi , Ue Hidenori , Sato Jun
Published: October 2023

This study was intended to exploit the possibility of using the quick gelation of alcogel that is induced by adding catalytic imidazole into a silicate-oligomer-based solution. For this purpose, the experimental viability of the direct observation of the gelation behavior was actually examined. The silicate oligomer, derived from tetraethyl orthosilicate hydrolyzed under an acidic condition (pH ~ 5), was used as the quickly gelling mother solution. The capability of the oligomer solution to form a non-flowable matter in only a few seconds when triggered by the addition of the catalytic solution of imidazole is promising, for example, for stabilizing a sandy ground surface, due to its simplicity. From the practical viewpoint, how long the gelation could take (=gel time) is a crucial parameter when the choice of an appropriate gelling chemical species needs to be made. Thus, this study focused its interest on as simple an experimental method as possible for evaluating the gel time of the gelling systems that actually underwent instantaneous gelation. The silicate oligomer solution was an appropriate material both in its quick gelling behavior and environmental friendliness. For such quick gelation, rheological approaches are not applicable for detecting the boundary in the mechanical properties that delineate the regime of “gel”. In this study, instead, direct observation was employed to capture the short interval during which the gelation was completed. The silicate-oligomer-based gelling solution was observed to lose its flowability within only 0.2 s, as it was seen to come off the bottom of the shaken cylinder at 5 Hz. For a more quantitative estimation, the same gelling solution was observed by high-speed motion picture. The high-speed motion picture could clearly capture the instantaneous gelation as a sudden arrest of the flow. The sub-millisecond direct observation of the gelation behavior revealed that the timescale of the instantaneous termination of the flow was as quick as 1 ms in order of magnitude. Such instantaneous gelation in the sub-millisecond-order timescale could not be forecasted from the observable megascopic gelation, which appeared to last from 102 ms to 103 ms in our naked-eye observation. The noteworthy gap between the timescale of the naked-eye-observed gelation and that of the true gel time at a localized spot determined by the high-speed motion picture should be noted to avoid excess agitation, which can result in total collapse into gel fragments of the just solidifying or already solidified gel under strong deformational influence by mechanical agitation, for example.

Authors: Li Hui , Yu Dongsheng , Ke Zhixuan
Published: October 2023

Taking the commercial system reform implemented in recent years as a “quasi-natural experiment”, this paper systematically examines the relationship between commercial system reform and enterprise ESG performance and analyzes the intermediary effect of enterprise green innovation between the two, based on the data of China’s commercial system reform and A-share listed companies in 2011–2021. The results show that the implementation of commercial system reform improves the level of ESG performance of enterprises, and green innovation of enterprises plays a positive role in the impact of commercial system reform on ESG performance of enterprises. After passing several robustness tests, the results of this paper are still valid. The results of the heterogeneity test show that the implementation of commercial system reform plays a greater role in promoting the ESG performance of state-owned enterprises, high-tech enterprises, high-financing-constraint enterprises, and high-pollution enterprises. The conclusions of this paper provide certain enlightenment for further promoting the reform of the commercial system and the construction of the ESG system and promoting enterprises to improve the level of modern green governance.

Chemical management of the peach fly, Bactrocera zonata has been compromised due to adverse effects of pesticide residues that not only contaminate environment but also affect non-target organisms including beneficial insects, birds, aquatic life, and soil microorganisms. They can be impacted through direct exposure or by consuming contaminated prey or plants. The present study was designed keeping in view this increasing demand of the consumers to get pesticide residue free fruit and vegetable produce because it reflects the growing consumer concern for food safety and environmental sustainability, motivating the need for alternative pest management strategies. The field experiment was conducted to determine the best slow-release formulation prepared by mixing the following five different types of waxes, including Candelilla wax (CanW), Paraffin wax (PW), Carnauba wax (CarW), Lanolin wax (LW) and Bees wax (BW) with methyl eugenol (ME) (to attract male B. zonata). The selection of the five different types of waxes was likely based on their biodegradability, availability, and potential for slow-release properties. The result revealed that formulations containing SRF-7[LW], SRF-9[CanW], SRF-8[BW], SRF-9[CarW] and SRF-9[PW] exhibited the maximum capture of 42.10 ± 8.14, 43.30 ± 1.76, 34.30 ± 2.96, 35.30 ± 3.18 and 22.70 ± 3.18 male B. zonata per trap per day, respectively. These effective formulations were further evaluated in experiment in which the comparative trapping efficiency of each wax formulation was assessed. The results demonstrated that formulation containing SRF-9[CanW] was expressed maximum capture 13.77 ± 1.26 male B. zonata per trap per day. These formulations were further evaluated in another experiment in which the trapping efficiency was assessed by four different application methods (simple bottle trap, simple bottle trap with water, yellow sticky trap and jute piece with sticky material). The results demonstrated that formulation containing SRF-9[CarW] applied by yellow sticky trap (YST) trapped 61.74 + 7.69 male B. zonata per trap per day and proved more effective. This formulation can be recommended for trapping and management of male population of B. zonata in fruit orchards. This study can influence eco-friendly B. zonata pest control policies, reducing chemical pesticide usage and promoting agricultural sustainability. Future research should study the long-term impact of slow-release formulations on agricultural sustainability, including pest control, crop yield, and agroecosystem health.

Published: October 2023

The possibility of using materials from the waste of agricultural products for the conservation of cultural and artistic heritage has led to important technological developments on mortars, plasters, colors, and other applications. In this experimental work, we investigated the binding properties of mucilage obtained from two different species of the genus Opuntia, both collected in Sicily, Italy: Opuntia ficus-indica (L.) Mill. and Opuntia stricta (Haw.) Haw. Through chemical acid hydrolysis, and subsequent spectroscopic analysis conducted at 13C-NMR, the main monosaccharide composition of both mucilage was studied, identifying considerable compositional differences. In fact, the mucilage of O. ficus indica had similar total amounts of arabinose (23.65%), galactose (20.87%), and glucose isomers (23.89%), while that of O. stricta was characterized by significant amounts of arabinose (36.48%) and galactose (32.31%) units. The samples were obtained by dispersing pigments on the mucilage and applying the obtained tempera by a brush onto both paper and chalk supports, in order to observe if the colors changed with different substrates. Colorimetric analysis, measuring ΔE, showed how the same pigment modifies its aspect depending on the binder used. After a two-week UV ageing process, pigments that had dispersed in O. stricta changed their aspect more than those dispersed in O. ficus-indica. Overall, it is also evident how ΔE data for organic pigments are higher than those for inorganic ones.
Genome-Wide Profiling of Transcriptome and DNA Methylome in Human Embryonic Stem Cells Exposed to Extractable Organic Matter from PM2.5
Authors: Wang Jianming , Liu Tiantian , Wang Jin , Chen Tao , Jiang Yan
Published: October 2023

Increasing evidence indicates that PM2.5 exposure disrupts early embryonic development, but the mechanisms remain unclear. We hypothesized that PM2.5 cause abnormal embryonic development by interfering with DNA methylation and mRNA expression. In this study, we observed that human embryonic stem cells (hESCs) treated with extractable organic matters (EOM) from PM2.5 concentrations above 100 μg/mL exhibited reduced viability. While EOM within non-cytotoxicity concentrations did not affect the expression levels of pluripotency genes, it did enhance cellular proliferation, as indicated by increased Edu incorporation and the upregulation of cell cycle genes (Cdk2, Mdm2). Additionally, EOM significantly influenced the transcriptome patterns in hESCs. Notably, the differentially expressed genes were found to be significantly enriched in processes such as extracellular matrix organization, cell–cell junction organization, chromatin organization, and DNA methylation. Furthermore, we observed whole genomic-wide DNA methylation changes. Through a cross-analysis of changes in DNA methylation and mRNA expression, we identified an enrichment of terms related to the VEGFR signaling pathway and extracellular matrix. The gene signal transduction networks revealed that crucial hubs were implicated in cell growth and division. In conclusion, our findings demonstrate that PM2.5 induce significant alterations in transcriptome and DNA methylome in hESCs, leading to aberrant cell proliferation. This research provides novel insights into the molecular mechanisms underlying the developmental toxicity of PM2.5.

Published: October 2023

Nontyphoidal Salmonella enterica (NTS) is a leading cause of foodborne illness worldwide, including in the United States, where infants show the highest incidence amongst all age groups. S. enterica serovar Typhimurium is one of the most frequently isolated serovars from NTS infections. We have developed several candidate live-attenuated S. Typhimurium vaccines to prevent NTS infection. The goal of the current study was to assess three live S. Typhimurium vaccine strains (CVD 1921, CVD 1921 ∆htrA and CVD 1926, which have two, three and four gene deletions, respectively) with various levels of reactogenicity and immunogenicity in infant BALB/c mice to predict how they would perform following peroral immunization of infants. We first tested intranasal immunization of 14-day-old mice with three doses delivered at 1-week intervals and evaluated antibody responses and protection against lethal infection with wild-type S. Typhimurium. The vaccines were administered to 14-day-old mice via the peroral route at 1- or 2-week intervals and to 28-day-old mice at 2-week intervals. The three vaccine strains were immunogenic following intranasal immunization of infant mice with vaccine efficacies of 80% (CVD 1921), 63% (CVD 1921 ∆htrA) and 31% (CVD 1926). In contrast, peroral immunization of 14-day-old mice yielded much poorer protection against lethal infection and only immunization of 28-day-old mice at 2-week intervals showed similar protective capacity as intranasal administration (CVD 1921: 83%, CVD 1921 ∆htrA: 43% and CVD 1926: 58%). CVD 1921 was consistently more protective than both CVD 1921 ∆htrA and CVD 1926, regardless of the route of vaccination, immunization schedule and age of mice. Anti-LPS serum IgG responses were similar between the three strains and did not correlate with protection. Due to previously observed reactogenicity of CVD 1921, CVD 1921 ∆htrA and CVD 1926 are our preferred vaccines, but these data show that further improvements would need to be made to achieve suitable protection in young infants when using peroral immunization.
Overview of the Biotransformation of Limonene and α-Pinene from Wood and Citrus Residues by Microorganisms
Authors: Ndao Adama , Adjallé Kokou
Published: October 2023

This review provides an overview of the biotransformation of limonene and α-pinene, which are commonly found in wood residues and citrus fruit by-products, to produce high-value-added products. Essential oils derived from various plant parts contain monoterpene hydrocarbons, such as limonene and pinenes which are often considered waste due to their low sensory activity, poor water solubility, and tendency to autoxidize and polymerise. However, these terpene hydrocarbons serve as ideal starting materials for microbial transformations. Moreover, agro-industrial byproducts can be employed as nutrient and substrate sources, reducing fermentation costs, and enhancing industrial viability. Terpenes, being secondary metabolites of plants, are abundant in byproducts generated during fruit and plant processing. Microbial cells offer advantages over enzymes due to their higher stability, rapid growth rates, and genetic engineering potential. Fermentation parameters can be easily manipulated to enhance strain performance in large-scale processes. The economic advantages of biotransformation are highlighted by comparing the prices of substrates and products. For instance, R-limonene, priced at US$ 34/L, can be transformed into carveol, valued at around US$ 530/L. This review emphasises the potential of biotransformation to produce high-value products from limonene and α-pinene molecules, particularly present in wood residues and citrus fruit by-products. The utilisation of microbial transformations, along with agro-industrial byproducts, presents a promising approach to extract value from waste materials and enhance the sustainability of the antimicrobial, the fragrance and flavour industry.

Published: October 2023

Frequent animal–human interactions in sub-Saharan Africa (SSA) pose an increased risk for the transmission of zoonotic diseases. While there are sporadic reports of zoonotic diseases outbreaks in SSA, a synthetic overview is necessary to better understand how the sub-region is impacted by these pathologies. We conducted a systematic review of zoonotic diseases studies conducted in SSA between 2000 and 2022. Quantitative reports including case reports/series from countries spanning West, Central, East, and Southern SSA and that provided empirical data on the occurrence of zoonotic diseases in humans with documented evidence of animal origin were eligible for inclusion. The 55 eligible articles provided 82 reports of zoonotic diseases for a total of 28,934 human cases (pooled attack rate: 54.4 per 1000) and 1182 deaths (pooled fatality rate: 345.4 per 1000). Only 31 (37.8%) of the studies were conducted during ongoing outbreaks. We identified the zoonotic diseases in SSA with the highest attack rates (rickettsiosis, toxoplasmosis, Q-fever) and CFR (Marburg, Ebola, leptospirosis), which should be prioritized for surveillance and response preparedness. Addressing the threat of zoonotic diseases in SSA requires the strengthening of health systems and implementation of a one health approach. Importantly, research should be encouraged during ongoing epidemics to fortify immediate response strategies and work toward preventing future outbreaks.

The current situation concerning rail freight transportation in the Russian Federation has become complicated by the fact that operator companies, without taking into account the technological features of railway transport, manage its rolling stock according to the principle of «the most profitable transportation». Using current technology, operators not only increased the cost of transportation itself, but also increased the transport component of each cargo transported by rail, including socially significant ones. The technology of operation of operator companies to a small extent takes into account the carrying capacity of the trunk and station infrastructure and the load factors of other railway transport resources.

The mechanism of solving the actual problem of forecasting technical impacts and residual life depending on the operating time in operational modes is presented. As a methodological basis, it is proposed to use the theory of experimental planning, provided that the factors are independent, controllable, all their combinations are possible, and the objective function can be measured. As factors, the values that determine the operating mode are used: the speed of rotation of the crankshaft, temperature, engine load, etc. Such a task in the article is called by the authors the first forecasting task. The practical implementation of this mechanism will allow the driver to display a variation series of the residual resource to failure in real time

In the paper, protective coatings on titanium were obtained by an electrochemical method using electrolytes based on ethylene glycol, glycerin, ammonium fluoride, and sodium silicate. The surface morphology was studied by metallographic and scanning probe microscopy (SPM), the nature of the coatings obtained was proved by infrared spectroscopy (IR-) and Raman spectroscopy (RS-). The surface morphology of the original sample is a set of grooves (distance 10-140 µm according to SPM and metallography). After electrochemical treatment, the surface mor-phology changed: a system of pores up to 30 nm in size was formed for the electrolyte based on gly-cerol and a developed amorphous surface consisting of globules, pores 500 nm and 250 nm in size for electrolytes based on ethylene glycol and ammonium fluoride, respectively. After electrolysis in sodium silicate solutions, a coating is formed whose elements are globules sized from 40 to 200 nm, combined into elongated ones. Analysis of the IR and Raman spectra showed the formation of a film of titanium oxide (rutile modification) and titanosilicate (titanite type).
