Abstract. Trajectory planning for flexible manipulators is a critical area of research in robotics. A trajectory tracking controller can enhance the accuracy of the manipulator's path and reduce vibrations. However, current flexible manipulators remain largely in the research phase, with many studies revealing issues such as poor accuracy in dynamic modeling, weak tracking performance in controller design, and insufficient vibration suppression capabilities. To address these challenges and improve the trajectory tracking performance of the manipulator, this paper focused on vibration suppression and trajectory planning for a two-link flexible manipulator and proposed a novel control method that integrates a modified adaptive particle swarm optimization algorithm (MAPSO) with fuzzy proportional–derivative (PD) control to achieve effective trajectory tracking. Firstly, the dynamic equations of the two-link flexible manipulator system were derived using the assumed modal method in conjunction with Lagrangian dynamics. Next, a 3-5-3 hybrid polynomial algorithm based on MAPSO was proposed to optimize the trajectory of the manipulator. Simulation results demonstrated that the optimization algorithm significantly enhances efficiency. Specifically, the number of iterations required for the two joints was reduced by 33 % and 54 %, respectively, when compared to the original algorithm. Additionally, this optimization led to a total reduction in running time of 0.03 s. Subsequently, the MAPSO algorithm was utilized to enhance the fuzzy PD controller based on the previously obtained optimal trajectory, leading to the development of a trajectory tracking controller known as MAPSO-FuzzyPD. Simulation results indicated that the proposed algorithm significantly reduced the maximum starting torque for both joints. Specifically, the maximum starting torque of joint 1 was decreased by 61.3 % and 40.3 % when compared to PD control and fuzzy PD control, respectively. Additionally, the maximum starting torque of joint 2 was reduced by 57.9 % and 42.1 % in comparison to the same control methods. Finally, an experimental platform for the flexible manipulator was established, and the experimental results further validated the effectiveness and feasibility of the algorithm proposed in this paper concerning joint trajectory tracking.

Рассмотрены архитектурные и алгоритмические принципы создания системы идентификации объектов окружения для задач движения мобильных дронов в системе мониторинга периметра сельскохозяйственных угодий. Построение системы идентификации предполагает гибридизацию алгоритмов обнаружения объектов (YOLO, Faster R-CNN) и машинного обучения с использованием метода опорных векторов (SVM) для классификации обнаруженных объектов. Практическая значимость предлагаемого решения заключается в автономном контроле над перемещениями дронов в случае нарушения спутниковой привязки и отсутствия связи с пультом оператора. Гибкость системы обеспечивается многокомпонентной модульной компоновкой, что дополнительно дает возможность адаптировать систему под конкретный набор задач.
The paper considers architectural and algorithmic principles of creating a system of identification of environmental objects for the tasks of mobile drone movement in the system of monitoring the perimeter of agricultural land. The construction of the identification system involves hybridisation of object detection algorithms (YOLO, Faster R-CNN) and machine learning with the use of support vector method (SVM) for classification of detected objects. The practical significance of the proposed solution lies in the autonomous control of drone movements in case of satellite fixation violation and lack of communication with the operator's console. The flexibility of the system is ensured by a multi-component modular layout, which additionally makes it possible to adapt the system to a specific set of tasks.

Navigating Transnational Identities with Zerocalcare and Takoua Ben Mohamed: Integrating Comics and Translation in Italian Language Courses
Authors: Fognani Arianna 
Published: February 2025

Abstract
This article examines the intersection of the transnational turn in Italian studies with the teaching of Italian language in lower division courses. It explores how comics and translation can be effectively employed to foster intercultural understanding and expand students’ perspectives on culture and identities. By engaging with emerging multilingual and transnational authors like Zerocalcare and Takoua Ben Mohamed, students gain insight into the complexities of Italian society and the diversity of the voices that creatively produce cultures. Translation practices, in turn, enhance their linguistic proficiency and their ability to position themselves between languages and cultures. This pedagogical approach, implemented through collaborative translation projects of Zerocalcare's A.F.A.B. and Ben Mohamed's Il mio migliore amico è fascista, has proven to effectively engage students in meaningful conversations about society, identity, and the broader transnational context of Italian culture. The projects, completed by second and third semester language learners, have resulted in enhanced intercultural awareness, deeper understanding of Italian identities, and a more nuanced appreciation of the language learning experience.

The present analysis investigates the possibility of using a tapered mast profile for bladeless wind turbines (BWTs) to enhance the function of extracting wind energy through the phenomenon of vortex-induced vibrations. Conventional HAWTs which remain the most efficient are however, costly in maintenance, mechanically complicated and rather unfavourable to the environment. To overcome these challenges a prototype BWT with a 0.6 m tapered mast was developed for the currents using mild steel and hollow square steel sections. Wind tunnels were also used to compare stress distribution, structural deformation and vane vortex shedding for the building at different wind speeds. The maximum calculated equivalent stress on the mast was 1.63 ´ 105 Pa with the total deformation achieving 1.732 ´ 10‒6 m at a wind speed of 4 m∙s‒1. The tests have represented an independent check on mast dynamics using recorded wind at an average of 7 m∙s‒1 and have quantified the observed oscillations marking validity of the dynamic behavior observed through simulations. Piezoelectric sensors deployed to measure mechanical stress produced voltage responses of 7.68 mV, 28.865 mV and 44.915 mV at wind velocities of 5.5 m∙s‒1, 6.1 m∙s‒1 and 7.8 m∙s‒1 respectively. Findings show that wave amplitude of the oscillations increases with wind velocity and concomitantly voltage generated. The study highlights the potential of tapered mast geometries in improving structural efficiency and energy output.

Published: February 2025

Background: In this study, we aimed to assess the pre- and postoperative thoracic and mediastinal volumes in patients who received minimally invasive pectus excavatum repair for pectus excavatum.
Methods: Between January 2017 and January 2022, a total of 51 patients (41 males, 10 females; mean age: 15.5±3.5 years; range, 9 to 33 years) who underwent received minimally invasive pectus excavatum repair were retrospectively analyzed. The pre- and postoperative (after bar removal) thoracic computed tomography scans of the patients were evaluated and the mediastinal, lung, and thoracic volumes were calculated using stereological techniques.
Results: The mean pre- and postoperative Haller Index was 3.87±1.32 and 3.28±0.86, respectively. The mean preoperative lung volume-to-preoperative thoracic volume ratio was 79.52±5.15% and the mean postoperative lung volume-to-postoperative thoracic volume ratio was 78.86±6.05%. The mean preoperative mediastinal volume-to-thoracic volume ratio was 20.48±5.15%, and the mean postoperative mediastinal volume-to-thoracic volume ratio was 21.14±6.05%.
Conclusion: Our study results showed no statistically significant increase in the thoracic and mediastinal volumes calculated using stereological methods, while the Haller index values regressed in all patients. These findings suggest that while there may not be a qualitative increase in thoracic and mediastinal volume, there is a quantitative increase in the anteroposterior plane.

Published: February 2025

Background: Frailty assessment for risk prediction is suggested in elderly patients undergoing cardiac surgery. We aimed to compare five different frailty tests.
Methods: Relation of Edmonton Frailty Score (EFS), Fried Frailty Phenotype (FFP), FRAIL (Fatigue, Resistance, Ambulation, Illness, and Loss of weight), Katz and hand grip strength (HGS) tests to each other, postoperative outcomes and mortality rates were evaluated prospectively in 140 consecutive patients aged ≥65 years.
Results: The median follow-up period was 880.5 (range, 0 to 1,237) days with higher EFS and FFP scores in non-survivors (p<0.05). Patients with any complication had higher EFS (p=0.002), FFP (p=0.004) and FRAIL (p=0,006) scores. Compared to non-frail patients, frail patients’ NYHA capacity, EuroSCORE II and STS mortality risks were higher; hemoglobin values and HGS were lower with EFS, FFP, and FRAIL tests. Frail patients’ hospitalization periods with EFS (p=0.003) and intensive care unit stay with FFP (p=0.029) were longer. No mortality was observed in non-frail patients according to the FFP test. The Kaplan-Meier (KM) log-rank survival curves showed significant differences in favor of non-frail subgroups according to EFS, FFP and HGS tests (p<0.05). Relative risks for mortality in frail and pre-frail patients were between 0.9 and 4. The FFP was the most sensitive test (area under curve=0.721). There was discordance rather than concordance among five different tests (Kappa <0.411).
Conclusion: For patients aged ≥65 years undergoing heart surgery the FFP can be used safely to determine non-frail patients. Although the EFS seems to be promising to identify frail patients, further large-scale studies using various tests are needed to predict an optimal cut-off value for this patient population.

Background: The study aims to identify factors associated with mortality in elderly patients undergoing surgery for acute limb ischemia.
Methods: Between October 2010 and January 2024, a total of 205 patients (106 males, 99 females; mean age: 77.7±8.0 years; range, 65 to 98 years) who underwent embolectomy for acute limb ischemia were retrospectively analyzed. Postoperative mortality and one-year mortality were designated as primary outcome measures. Multiple regression analyses were performed for variables related to postoperative mortality, and cut-off values for numeric variables were determined. The Kaplan-Meier survival analyses were performed using one-year mortality data.
Results: Postoperative mortality rate was 35.1% and oneyear mortality rate was 56.6%. A total of 52.8% of the patients who died postoperatively were functionally dependent and 72.2% had no history of atrial fibrillation. Multivariate analysis revealed that a neutrophil-to-lymphocyte ratio above 5.91 increased mortality by 9.1 times, functional dependency by 7.3 times, and absence of a history of atrial fibrillation by 3.3 times. Functional dependency, absence of atrial fibrillation, and neutrophil-to-lymphocyte ratio greater than 5.85 negatively affected one-year mortality.
Conclusion: Our study results indicate that absence of atrial fibrillation, functional dependency, and neutrophil-to-lymphocyte ratio can be used to predict postoperative mortality.

EFECTOS NEUROENDOCRINOS DE INSULINA, IGF-I Y LEPTINA SOBRE LA SECRECIÓN DE HORMONA LIBERADORA DE GONADOTROPINAS (GnRH)
Authors: Guzman Sanchez Adrian , Rosales-Torres Ana Maria , Gutierrez Aguilar Carlos Guillermo 
Published: February 2025

<p>Animal energy balance greatly determines his reproductive success. In the majority of mammals, under a negative energy balance, there is a decrease in the synthesis of the gonadotropin-releasing hormone (GnRH) which reduces the activity of the hypothalamic-pituitary-gonadal axis. When the energy balance is improved, the hypothalamus reacts to this change and reestablishes the secretion of GnRH. Insulin, the insulin growth factor I (IGF-I) and leptin seem to be the main messengers that signal the hypothalamus on the animal energy balance. It has been seen that the peripheral concentrations of these hormones under positive or negative energy states are associated with changes in GnRH secretion. This review shows how IGF-I acts directly on GnRH neurons affecting its synthesis and secretion, whereas that insulin and leptin act on neurons in the arcuate nucleus (ARC), which synapses with GnRH neurons in the medial preoptic zone. Both insulin and leptin decrease the expression of neuropeptide Y (NPY) and therefore the negative effect of NPY on GnRH secretion. On the other hand insulin and leptin stimulating the synthesis of galanin-like peptide (GALP) and proopiomelanocortin (POMC). Both GALP, as well as the POMC metabolites (mainly the melanocyte stimulating hormone) increase the synthesis of GnRH. Finally, leptin increases the expression of kisspeptin in ARC neurons. Kisspeptin has a positive effect on the synthesis and secretion of GnRH.</p>
