To address the challenges of difficult quantitative design and potential coil mismatch in auxiliary coils within wireless power transfer systems, a data-driven parameter optimization method based on multi-objective particle swarm optimization (MOPSO) was proposed. First, based on the inductor–capacitor–capacitor series (LCC-S) compensation topology, a mechanism-based analysis was conducted, establishing coil side length A and number of turns N as core optimization variables. Subsequently, a collaborative optimization framework integrating “parametric simulation–surrogate modeling–active learning” was established. An offline fingerprint database was constructed via finite element simulation, and a high-accuracy surrogate model was developed using a kernel ridge regression ensemble approach. Active learning strategies were employed to adaptively augment data points and mitigate uncertainty. Finally, the multi-objective particle swarm optimization (MOPSO) algorithm was applied to identify the Pareto-optimal solution set. Experimental results reveal that the optimized auxiliary coil parameters achieved positioning errors below 8 mm at all test points. The maximum positioning error was significantly reduced by approximately 80% compared to the traditional empirical approach, providing a useful parameter-selection reference for high-precision wireless charging alignment systems under the investigated static operating conditions.
Light industry is one of the oldest sectors of the world economy, which has developed rapidly under the influence of industrial revolutions, the introduction of technological innovations, the development of trade, increased competition in consumer goods markets and other factors, which formed special areas of the industry with its centers. Global trends and features of the development of light industry are of interest for spatio-temporal analysis necessary for understanding the problems of domestic production. The relevance of the study is due to the need for a scientific analysis of the development of key sectors of the light industry in the context of modern geopolitical and macroeconomic realities in the context of constituent entities and federal districts. Having a relatively small share in the structure of manufacturing, light industry plays an important role in the country’s economy, provides all its spheres with various types of products, and the population with consumer goods. Russia’s modern light industry has complex technological chains, relies on a diverse raw material base, it is focused on the growth of consumer demand, which requires the modernization of production. Radical changes in the sectoral and spatial structure of light industry in the world, as well as import substitution requirements have had a great impact on the state of the industry in the regions of Russia. Geopolitical challenges have shown that it is necessary to make maximum use of the existing potential by creating new production facilities, introducing modern technologies, forming our own raw material bases, and training personnel for the sustainable development of the industry. The post-Soviet crisis slowed down the development of light industry for a long time, but at present it is being renovated and transformed into a creative industry. The retrospective analysis reveals positive dynamics in the development of key sectors of light industry, despite the aggravation of a number of problems. Changes in the sectoral and territorial structure of the industry were identified, a typology of the subjects of the Russian Federation was made up by the share of light industry in the economy of the regions. Measures are proposed to bring the industry to a qualitatively new level of development.
The dynamic spread of 3D printing technologies and open-source electronics prototyping platforms has significantly enriched the diversity of instruments used within educational robotics (ER) settings. An active, low-entry-level community offering ready-to-use libraries for a broad variety of devices assists in the development of quite sophisticated projects. However, the flipside of the coin is represented by the current research findings, which reveal that students’ interest in science, technology, engineering and mathematics (STEM) subjects has declined across Europe, as manifested in difficulties when approaching scientific topics and dealing with problems and phenomena studied from a multidisciplinary perspective. Consequently, a significant percentage of youths are at risk of social exclusion due to the direct relationship between low academic achievements and school dropout. Moreover, learners lack guidance in applied and life-context skills, such as creative thinking, problem solving, and collaboration, which highlights the need to introduce innovative pedagogical approaches. In this context, the design thinking (DT) methodology was proposed to tackle the problem. Originating in the development of psychological studies on creativity in the 1950s within the educational context, DT is known to foster creative thinking, help develop empathy, promote action-oriented actions, improve meta-cognitive awareness, contribute to problem-solving skills, and enhance students’ imagination. The last point supports the students’ development of critical thinking, social inclusion, teamwork skills, and academic performance. Thus, this paper introduces a methodological framework combining DT with ER classes. First, to approach the problem, the teachers’ survey data were collected and analysed to reveal the respondents’ level of integration of the DT methodology into current school curricula. Then, the work focused on the application of this framework in a learning experience by addressing the weakest points established and their elaboration through the combined ER and DT classes in the context of secondary schools.
This paper concerns the results of the archaeological investigations at the Savelli fortress on the Aventine Hill in Rome. This fortification surrounds a well-known park of the city: the Giardino degli Aranci. The research has been addressed to improve the knowledge on a topic of great historical interest: the architectural typologies developed by Roman aristocratic families in order to defend their properties. Locating Rocca Savelli within a specific architectural typology is problematic, due to the lack of research on this site. The research team of the Department of History and Cultures of the University of Bologna has surveyed the remains, studied their building features and documented stratigraphic data. This paper summarises the preliminary results of such research effort. The structures still conserved above the ground level can be dated back to the second half of the 13th century and are the output of craftsmen specialised in building with local tuff. The fortification was most likely built by the Savelli family in order to defend its dwelling on the Aventine Hill. The next step of the research will be addressed to in-depth analyses of data collected during the fieldwork. The aim is to better specify the original features of the structure and its later modifications. At a later stage, it will be possible to understand the economic, cultural and ideological background of the people connected to the fortification (patrons, builders and inhabitants). Ultimately, the project will include geophysical prospections and small excavations across the park to investigate the presence of further structures conserved below the present ground level.
The study concerns children’s burials of the Srubnaya culture (Bronze Age, the South Urals). The assumption that grave goods are related to the gender and age of the dead and may also reflect the stages of growing up of children and their inclusion in economic life (gender and labour socialization) was the theoretical basis of the research. A sample consisting of 178 anthropologically identified individuals who died before the age of 15 years was analyzed. This sample was divided into three age sub-groups in order to catch the dynamics in distribution of the grave goods in accordance to age and in order to identify the different stages of children’s life course. The author’s study demonstrated that children before 2 years old were mostly accompanied by gender-neutral grave goods (ceramic vessels) or were buried without any items. After this age grave goods become more diverse and numerous. It is possible to suggest that gender socialization in the Srubnaya society started around the age of two-three but female gender was marked more often than male. The study of age dynamics demonstrates that as the children grew older, the number of jewelry increased, while other items were still few in number. Labour socialization was not reflected in burial rite. The perspective of the study is seen in the extension of the source base and further analysis of artifacts, including ceramic material.

The oppidum of Châteaumeillant (Cher) belongs to the civitas of the Bituriges, whose boundaries correspond approximately to those of the current departments of Cher, Indre, and to which portions of Allier and Loir-et-Cher must be added. Located about 60 km from Bourges/Avaricum (Cher), the capital of this territory, the Mediolanum of the Tabula Peutingeriana occupies a privileged position at the southern end of Berry, the oppidum having been installed on the highest part of a rectangular promontory measuring 60 ha. Discovered in the 19th c. by Émile Chénon, the oppidum of Châteaumeillant was the subject of major archaeological excavations in the 1950s and 1960s under the direction of Émile Hugoniot and Jacques Gourvest. From 2001 to 2018, subsequent excavations focused on the Gallic habitat, as well as on the imposing fortification. The excavations revealed a dense and continuous occupation that began around 200 BC, through the La Tène C2 period. As early as La Tène D1, around 150 BC, shipments of Italian amphorae poured into Châteaumeillant. Then, around 100 BC, the town was equipped with a murus gallicus enclosing the 27 ha of the southern half of the promontory. The site subsequently peaked in terms of growth, though the rate of Italian wine imports remained steady. During the Gallic War, the murus gallicus was reinforced by a massive rampart preceded by a 45 m wide flat-bottomed ditch (Krausz 2007a; 2014; 2019; 2021; Krausz, Millereux 2019). Traces of fire observed in the La Tène D2 habitat suggest that Châteaumeillant is likely one of the twenty Bituriges towns to have been burnt down at the behest of Vercingetorix (Krausz 2009a). The town was rebuilt in the Augustan period and the occupation of the promontory continued through to the present day, without interruption. In the areas explored between 2008 and 2018 (A to G), several buildings, constructed on posts, were excavated. Some of them were built overtop large quadrangular pits that would have served as cellars. The archaeological material discovered in this zone argues in favour of areas B and C having served a craftworking and commercial function, rather than as exclusively residential areas. The presence of cellars and large pits, which would have been used to store foodstuffs that might be used for trading would appear to corroborate this interpretation of function. It is in this part of the oppidum that the renowned “amphorae cellars” were discovered in the 19th c. It was only possible to explore one such cellar during the recent excavations (2012 to 2016) and it is therefore the object of study of this article. The cellar contained the remains of 33 Italic amphorae. During a second phase of use, a well (St 512) was dug in the eastern half of this cellar. Its protected excavation yielded an exceptional assemblage, dated to the final La Tène period: in addition to some 1,500 ceramic sherds, an anthropomorphic stone statue, a human skull with traces of de-fleshing and an andiron protome of a horse were deposited at the bottom of the well. The body of the andiron is complete and well preserved, decorated with a combination of white paint and engravings. The object measures 0.39 m in height, from the hoof to the top of the horse’s head. An anthropomorphic statue and a human skull were discovered in the layer above. The statue was lying face down, 10 cm from the human skull. This sculpture represents a male figure, whose head and right hand were preserved; the hand is holding a ring to the centre of the chest. Below this ring, the statue was previously and intentionally broken. Following this damage, the upper portion of the statue (head and torso) was deposited in the well, while the base was found in a small pit in Zone B, located 8 m north of the well. It is sculpted in the round, in a particularly fine Châteaumeillant sandstone, finer than that of the statue from well F.II of the Kasmareck Garden discovered within the oppidum in 1960. Both are, undoubtedly, Celtic busts. In addition to this type of bust, another category of statues are seated figures, recognizable by virtue of their crossed legs (Coulon, Krausz 2013). Sitting busts present one or both hands resting on the chest and often wear a torque around the neck. In the statue’s current state, and with the upper part combined with the lower part, it measures 0.50 m in total height. Overall, the width varies little: from the head (10 cm), through the torque and the shoulders (12 cm) to the lower portion (15 cm). Thus, there is a variation of 5 cm from top to bottom, resulting in a small but constant broadening. This slight variation confirms that the statue is part of a rectangular block that widens slightly towards the bottom. Below the right hand holding the ring, the lower block presents no further figural representation. However, it has been carved in such a way as to provide an end that was likely tapered or pointed, a feature that could have allowed the sculpture to be driven into the ground. As with other Gallic bust statues, certain anatomical and ornamental features are highlighted: the facial features, the hairstyle and the ears, the torque around the neck and the representation of the right arm and hand. As for the human skull, it was deposited in the pit without its mandible or any other accompanying skeletal element. Only the molars and premolars remain from the upper dentition, while the other teeth were lost post-mortem, though not within the well. The skull belonged to a young adult, whose age was estimated between 17 and 25 years of age. The sex is undetermined, but most likely male. Several incisions visible on the calvaria (or skullcap), as well as on the zygomatic processes of the temporal bones suggest that it was de-fleshed, removing the scalp, and detaching the mandible and atlas. The polished appearance of the frontal bone, along with a small eroded area in the centre could be the result of exposure to touching or weathering, at least in this anterior portion. Similarly, the cracking and darkening of the tooth enamel could be the result of being placed in an open-air setting. The loss of the canines and incisors is further indication of the possibility that the skull was exposed, possibly showcased in an elevated manner. The Gauls’ marked interest in heads is known from ancient times, and the practice of removing skulls and subjecting them to a particular treatment, separate from the rest of the skeleton is attested to in Gaul from the 5th to the 1st c. BC. The presence of these remarkable objects in well 512 reveals the unique and ritualistic nature of the deposit, in the context of the La Tène habitat. It combines the representation of a male figure set in stone with a severed head. Well 512 and cellar 437 constitute an exceptional archaeological ensemble, unprecedented in a La Tène period habitat. Indeed, it concentrates numerous cultural and social characteristics of the La Tène D period: statuary, a ritual deposit, wells and an amphora cellar. This collaborative article proposes a detailed study of the two structures, the objects discovered therein and their chronology.
Mjesni narodni odbor Bašanija djelovao je od 1947. do 1952. godine, kao upravno tijelo lokalnoga karaktera neposredno podređen Narodnom odboru kotara Buje (1945.– 1955.). Naslijedio ga je Narodni odbor Gradske općine Umag (1952. – 1955.) koji s radom počinje 1952. godine osnutkom Gradske općine Umag te čija teritorijalna nadležnost obuhvaća područje ukinutoga stvaratelja. Djelatnost Mjesnoga narodnog odbora Bašanija posebno se odnosila na ostvarivanje poljoprivrednog plana, brigu o materijalno-kulturnom napretku mjesta, obavljanje komunalnih poslova, unapređenje obrta i industrije te posredovanje u procesu razmjene dobara između grada i sela. Za vođenje administracije i izvršavanje odluka Narodnoga odbora bili su zaduženi njegov predsjednik i tajnik. Ostali su službenici od predsjednika i tajnika, kojima su bili odgovorni za svoj rad, dobivali zadatke po potrebi. Nakon prestanka rada stvaratelja gradivo fonda bilo je pohranjeno u arhivu Skupštine Općine Buje, odakle je 1977. godine, zajedno s gradivom povezanih stvaratelja, primljeno u Historijski arhiv – Pazin (danas Državni arhiv u Pazinu). Sređivanje i izrada sumarnoga inventara obavljeni su 2012. godine. Gradivo je sređeno sukladno sadržajno-funkcionalnom modelu sređivanja čuvajući prvobitni red. Cjeline »Opći spisi po broju« i »Povjerljivi spisi« ostavljene su kao zasebne serije dok je na nižoj razini gradivo složeno sukladno sadržajno-tematskoj problematici.
This study concerns the problem of diagnosing the materials of transitional period from the Bronze Age to the Early Iron Age on the territory of the Urals and Kazakhstan steppes. The purpose of the work is the presentation and analysis of new materials (the Shatmantamak I burial ground) using radiocarbon dating methods. On the basis of comprehensive analysis and comparison with synchronous and asynchronous materials, the authors concluded that the burial represents a rare example of a site marking the transition period from Final Bronze Age to the Early Iron Age. The results of dating for these periods were summarized for the territory from the Volga-Ural to East Kazakhstan to determine the position of new materials in the periodization system. Some of the results are published for the first time. Generalization of synchronous materials of the 9th – 8th centuries cal BC demonstrated a mosaic pattern of cultural traditions, as well as the asynchronous transition to the Early nomads Epoch in the territories west and east of the Ural Mountains. Unfortunately, the author’s conclusions rely on a relatively small series of dating results, which require significant expansion due to new analyses.
α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptors are assembled of four core subunits and several additional interacting proteins. Cystine-knot AMPA receptor-modulating proteins (CKAMPs) constitute a family of four proteins that influence the trafficking, subcellular localization and function of AMPA receptors. The four CKAMP family members CKAMP39/shisa8, CKAMP44/shisa9, CKAMP52/shisa6 and CKAMP59/shisa7 differ in their expression profile and their modulatory influence on AMPA receptor function. In this review, I report about recent findings on the differential roles of CKAMP family members.
