Robust H∞ Output Feedback Trajectory Tracking Control for Steer-by-Wire Four-Wheel Independent Actuated Electric Vehicles
Authors: Li Zhiwen , Jiao Xiaohong , Zhang Ting 
Published: June 2023

This paper investigates the trajectory tracking control issue of four-wheel independently actuated electric vehicles (FWIA EVs) with steer-by-wire devices concerning parameter uncertainties, external disturbances, input saturation, and vehicle sideslip angle not easily obtained. A robust H∞ dynamic output feedback control strategy is proposed for the integrated control of the steering motor current and direct yaw moment without using sideslip angle information to ensure the reference trajectory tracking and the improvement of handling performance and yaw stability. In the proposed integration control framework, the steer-by-wire device dynamic is involved in the polyhedral linear parameter-varying (LPV) trajectory tracking error model considering the time-varying longitudinal velocity, and the norm-bounded parameter uncertainties such as road adhesion coefficient, tire cornering stiffness, vehicle mass, and vehicle moment of inertia. With the help of the LPV model of all the states of the steer-by-wire FWIA EV, a dynamic output feedback trajectory tracking controller is designed using the robust H∞ technique. The controller gain matrices are obtained by solving the linear matrix inequalities. Finally, the high-fidelity full-vehicle model based on the CarSim-MATLAB/Simulink joint simulation platform verifies the robustness and advantages of the designed control strategy in the accelerated lane-change scenario.

BackgroundAntibiotics are commonly prescribed for children with lower respiratory tract infections (LRTIs), fuelling antibiotic resistance, and there are few prognostic tools available to inform management.AimTo externally validate an existing prognostic model (STARWAVe) to identify children at low risk of illness progression, and if model performance was limited to develop a new internally validated prognostic model.Design and settingProspective cohort study with a nested trial in a primary care setting.MethodChildren aged 6 months to 12 years presenting with uncomplicated LRTI were included in the cohort. Children were randomised to receive amoxicillin 50 mg/kg per day for 7 days or placebo, or if not randomised they participated in a parallel observational study to maximise generalisability. Baseline clinical data were used to predict adverse outcome (illness progression requiring hospital assessment).ResultsA total of 758 children participated (n= 432 trial,n= 326 observational). For predicting illness progression the STARWAVe prognostic model had moderate performance (area under the receiver operating characteristic [AUROC] 0.66, 95% confidence interval [CI] = 0.50 to 0.77), but a new, internally validated model (seven items: baseline severity; respiratory rate; duration of prior illness; oxygen saturation; sputum or a rattly chest; passing urine less often; and diarrhoea) had good discrimination (bootstrapped AUROC 0.83, 95% CI = 0.74 to 0.92) and calibration. A three-item model (respiratory rate; oxygen saturation; and sputum or a rattly chest) also performed well (AUROC 0.81, 95% CI = 0.70 to 0.91), as did a score (ranging from 19 to 102) derived from coefficients of the model (AUROC 0.78, 95% CI = 0.67 to 0.88): a score of <70 classified 89% (n= 600/674) of children having a low risk (<5%) of progression of illness.ConclusionA simple three-item prognostic score could be useful as a tool to identify children with LRTI who are at low risk of an adverse outcome and to guide clinical management.
Le double apport d’une sociohistoire de la diversité étudiante pour étudier les inégalités contemporaines : connecter les représentations, saisir les droits effectifs

Published: June 2023

Pendant de l’élargissement progressif du projet démocratique à l’ensemble des individus, la problématisation de l’accès à l’université en termes d’inégalité est propre à l’époque contemporaine. Pour autant, elle constitue le prolongement d’une problématisation relative à la diversité du corps estudiantin dont l’étude contribue à redéfinir les contours d’une analyse des inégalités : la qualification et la régulation de la diversité étudiante constituent un enjeu récurrent des universités. L’analyse de ce continuum, sur lequel revient la première partie, saisit le rôle de l’université comme creuset d’une représentation de la diversité sociale et l’abondement d’une structure sociale multidimensionnelle (partie 2). Du traitement politique de cette multidimensionalité découlent des processus macrosociaux à l’origine d’inégalités d’accès que la perspective historique permet de dévoiler (partie 3).
Erasmus : la mobilité hybride au secours de l’inclusion ?
Authors: Ballatore Magali 
Published: June 2023

Depuis la création du programme Erasmus (acronyme signifiant EuRopean Action Scheme for the Mobility of University Students) en 1987, la forme et l’étendue des échanges d’apprenants, au sein de l’Union européenne, ont beaucoup changé. Jusqu’à récemment, seul le niveau supérieur de l’enseignement supérieur et sa communauté éducative était concerné par l’institutionnalisation de la mobilité. Erasmus+ englobe aujourd’hui d’autres types d’échanges et touche plus largement la jeunesse européenne. Cet article est une synthèse de l’évolution des politiques et actions publiques éducatives européennes autour de la mobilité. Nous aborderons aussi la question de l’évolution des discours qui accompagne ces politiques, concernant l’existence d’une « génération » Erasmus notamment, et celle des trajectoires que ce programme permet, en fonction des segments et des niveaux de l’enseignement concerné, de l’enseignement supérieur à l’enseignement obligatoire.

Article presents the research results on the respiratory activity and redox capacity of granulose layer cells of cow ovarian follicles under the physiological state of follicular growth. After the slaughter of the cows, the ovaries in physiological state of follicular growth were selected and the size of the follicles was evaluated. Cells of the granulosa layer were aspirated from small (< 4 mm), medium (4–7 mm) and large (> 7 mm) follicles and determined: intensity of oxygen absorption – polarographically, redox capacity – potentiometrically. K3[Fe(CN)6] was used as an extracellular electron acceptor. The share of oxygen consumed by aerobic glycolysis was determined by using sodium fluoride inhibitor, the NAD-dependent link of the mitochondrial electron transport chain - amytal, and the terminal (cytochrome oxidase) – sodium azide. The share of free-radical oxidation of unsaturated fatty acids in the realization of oxygen was detected by Na2EDTA.
Granulosa cells from the ovary of follicular growth are characterized by respiratory activity and regenerative capacity, the intensity of which depends on the size of the follicles from which they are extracted. The highest values of the investigated indicators are characteristic of cells extracted from large follicles, lower – from small follicles, and the lowest values are from medium follicles. The high intensity of oxidative processes in granulosa from small follicles ensures the growth of oocytes, and from large follicles – maturation of the germ cell in the dominant follicle. At the same time, the increased intensity of oxygen consumption by the cells of small and dominant follicles is manifested against the background of limitations in electron acceptors in the extracellular environment.
The use of inhibitors of ATP resynthesis of both glycolysis and individual links of the mitochondrial respiratory chain testify the activity of the indicated metabolic pathways in granulosa and the possibility of using alternative substrates to ensure the existence of cells. The main way of utilization of oxygen in the granulosa layer cells of small and large follicles is aerobic glycolysis, and from the medium there are alternative ways of supplying and using substrates. The largest flow of reducing equivalents into the extracellular space from the granulosa of a medium-sized follicle due to inhibition of glycolysis indicates that the source of the supply of reducing equivalents into the follicle cavity is glycolysis and this characterizes the dependence of the existence of cells on the indicated metabolic pathway.
BIOLOGICAL ROLE AND ANTIOXIDANT ACTIVITY OF MICROELEMENTS AND VITAMINS IN LIVESTOCK OF ANIMALS
Authors: Velichko V. O. 
Published: June 2023

One of the urgent problems of veterinary medicine, especially in modern conditions of wartime, is to increase the vitality of animals, preserve their health and productivity potential. It is important to maintain the vital activity of animals at various stages of their development. Keeping animals in unfavorable conditions, including man-made loads, unbalanced feeding lead to a decrease in their productivity, the occurrence of secondary disorders of a metabolic and functional nature, and a decrease in their non-specific and specific resistance. Under these conditions, the ability of the organism to mobilize protective and adaptive capabilities in response to the action of negative technological and environmental factors becomes especially important. Micronutrients and vitamins play a leading role in mobilizing the body's adaptive capabilities. It should be noted that at the moment, quite a few formulas of mineral-vitamin feed additives have been developed and registered in Ukraine for the correction of rations, which contribute to increasing the productivity and resistance of animals, improving the quality of products - milk and meat.
Science and practice have proven that trace elements and vitamins affect the regulatory systems of the animal body. The mechanism of their pharmacological action is related to the intensity of protein synthesis, under their influence the activity of enzymes of carbohydrate and fat metabolism is regulated, the growth and development of animals are activated. It was also established that microelements perform a protective function of the body by eliminating radical reactions, thereby preventing damage to cell membranes and biological macromolecules.
On the basis of this, it is possible to draw certain conclusions that microelements and vitamins have antioxidant activity, and accordingly increase the activity of the antioxidant protection system. In addition, they perform a number of extremely important biological functions in the body: they not only stimulate the activity of antioxidant defense enzymes, but also have antimicrobial and antifungal effects. And this, in turn, has a complex effect on the quality of products, the consumption of which can be attributed to the rational and preventive nutrition of people.

Published: June 2023

Governments of many countries and professional organizations, including Ukraine, have developed a lot of legislative and regulatory documents and recommendations to tackle the development of acquired antimicrobial resistance, based on the of “One Health” concept. Monitoring the manifestation of acquired antimicrobial resistance and the circulation of antimicrobial veterinary medicinal products is one of the keys to solving this problem.
The main goal of this study was to determine the trends in the sales volumes of antimicrobial veterinary medicinal products and compare them with the turnover of such products in the EU/EEA member states during 2021.
Since 2015, the World Organization for Animal Health (WOAH) has taken the lead to build a global interactive automated database on antimicrobial agents ANIMUSE to facilitate countries' reporting, analysis, and interpretation of data. In 2022, Ukraine, like other countries, for the first time submitted an annual sales volumes report of antimicrobial veterinary medicinal products online to the global ANIMUSE database on the antimicrobials intended for use in animals (AMU).
As a result of the sales volumes reports of antimicrobial veterinary medicinal products analysis for 2021, common trends were revealed in Ukraine and EU/EEA member states regarding the circulation of antimicrobial veterinary medicinal products of category D, in particular tetracyclines and penicillins. However, was established an increase in the sales share of aminoglycosides (7.93 %), polymyxins (8.5 %) and fluoroquinolones (10.4 %), and the 3rd and 4th generation cephalosporins (0.72 %) in Ukraine, which are classified as categories C and B, the use of which must be reasonable in the absence of alternatives from category D.
Monitoring data of sales volumes does not allow us to assert that all of the sold antimicrobials were used during the reporting period, however, the increase in their share in sales volumes is worrisome following the requirements stated by the “Procedure for the use of antimicrobial veterinary medicinal products”, approved by order of the Ministry of Economy of Ukraine No. 1177-21 of 12.30.2021.

The article highlights the results of using a feed additive based on spore-forming bacteria of the genus Bacillus when growing broiler chickens. The addition of the studied additive to the diet of chickens in the first group at a dose of 0.5 and to the second group at a dose of 1 g/kg of feed increased the intensity of the bird's growth. In particular, the average daily weight gain of broilers in the experimental groups was, respectively, 11 and 11.8% higher than in the control group.
At the same time, the yield of gutted broiler carcasses in the first and second experimental groups was higher, compared to the control group, by 245 and 275 g, respectively. Under these conditions, in the first experimental group with an average body weight of 2411.1 g, feed consumption during the experimental period was 4310 g/head, while feed conversion was 1.78. In the second experimental group with an average body weight of 2426.9 g, the feed consumption was 4253.3 g/head and the conversion was 1.75, while in the control group with an average body weight of 2178.4 g, the feed consumption was 4433.3 g/head, and the feed conversion was 2.03.
When identifying microorganisms of the Enterobacteriaceae family, in the first research group were found: Escheriсhia coli, Escheriсhia fergusonii, Escheriсhia hermannii, Escheriсhia vulneris, Serratia odorifera; in the second experimental group: Escheriсhia coli, Escheriсhia fergusonii, Serratia odorifera, Kluyvera spp.; and in the control group: Escheriсhia terioteria enorita, Serratia oderofera cloacea, Shigella spp. Microorganisms of the genus Salmonella, and also Campilobacter and C. perfringens on day 42 in broilers of all groups were not detected.
Therefore, the use of a feed additive based on spore-forming bacteria of the genus Bacillus leads to a decrease in feed conversion, an increase in the body weight of birds, and an increase in total and average daily weight gain, compared to the control group. Also was found the positive effect of feed additives on the qualitative and quantitative composition of the intestinal microflora, while the microflora of the bird is corrected in the direction of an increase in the normal flora and a decrease in pathogenic and conditionally pathogenic microflora.
