"Vestments of the Cross": historical realities and artistic image of the bishop liturgical vestments
Authors:   St. Sophia Cathedral, Veliky Novgorod, Lepshina L.A.
Published: December 2024

The article examines the typology of the fabrics of the bishops' vestments of the 14th-16th centuries woven or embroidered with a pattern of multiple (or only four) crosses and traces their attribution to specific historical persons. The dating of the phelonion of such kind from the collection of the Novgorod Museum-Reserve, in the State Catalog of the Museum Fund of the Russian Federation accompanied by dating to the 15th century, is revised; the assumption is justified about the possibility of its attribution to the Novgorod Archbishop Moses (+1363). Based on the analysis of the changes in the typology of the decoration of some phelonion-polystavrion and phelonion with four crosses figured as liturgical vestments in the frescoes, icon painting, illuminated manuscripts and liturgical embroidery of the 12th -16th centuries, as well as a more careful interpretation of written sources, the attribution of some cross-decorated felonies of the Novgorod bishops is clarified.
Two Post-Byzantine Icons from the Rozhen Monastery
Authors:   Bulgarian Academy of Sciences, Penkova B.
Published: December 2024

The article examines two icons of the Mother of God kept in the Rozhen Monastery of the Nativity of the Mother of God, located near the medieval town of Melnik in southwestern Bulgaria. The icon of Our Lady of Tenderness is a fairly accurate reproduction of a copy of the miraculous Vladimir Icon of the Mother of God, which came to the Balkans shortly after its creation in Moscow in the first half of the 16th century. Dendrological analysis of the icon board showed that it was probably made in the region from a local species of pine. On the other hand, the rare epithet Alithini has its roots among the knights of the Crusaders on Rhodes. The second icon with the unique epithet of Rhetorissa reproduces the iconography of the Hodegetria, but in the hands of the Mother of God, in addition to the Child, there is a stone wall with a tower, behind the wall a half-length image of Christ the Great Hierarch, on the other side of the tower there is a stone with a tree, a ladder and a red wheel, above it a large arc. In this form, all these objects are unknown in the works of Byzantine and post-Byzantine art, but some of them are part of only Russian iconographic types of the Mother of God of the Uncut Mountain and the Mother of God of the Burning Bush. The creator of the Rozhen icon borrowed elements from both, interpreting them in the context of the Byzantine tradition. The key to the unusual program is the unique epithet. The icons from the Rozhen Monastery are unique works of post-Byzantine Balkan painting, which reflect the most characteristic moments in the artistic thinking of the era between the Middle Ages and the Modern Era.

Authors: Oruç Sevim , Eken Meltem
Published: December 2024

Throughout history, natural and man-made disasters have caused severe humanitarian crises, both worldwide and in Turkey. These disasters have necessitated extensive humanitarian aid as well as efficient and rapid logistics management. This article analyzes the role of maritime transportation in disaster management and humanitarian aid processes in Iskenderun Region, with a focus on the 6 February 2023 earthquakes in Turkey. Utilizing literature through reviews, surveys, and data analyses, the study examines the effectiveness of maritime transportation in disaster response activities. The results of the survey conducted with 161 participants indicate that maritime transport plays a critical role in disaster management processes. While the majority of participants expressed that maritime transport provides a rapid and effective response to disasters, some participants highlighted the need for infrastructure improvements to enhance the efficiency of these processes. These findings suggest that the current maritime transport infrastructure requires strengthening to improve its effectiveness in disaster management. Most of the participants highlighted the rapid and effective responses enabled by maritime transportation and humanitarian aid processes, but some emphasized the need to strengthen its infrastructure.

Published: December 2024

The article presents the results of a study of the current state of soil fertility of the SEC Asia Agro Group of the Shaulder irrigation area of the Turkestan region. It has been established that the limiting factor in the yield of SPK «Asia Agro Group» is the content of humus and easily hydrolyzed nitrogen. This is due to the mineralization of humus and the need to compensate for it through the additional application of organic and nitrogen fertilizers. In addition, it is necessary to increase the nitrogen content in the soil by introducing perennial grasses into the crop rotation, because after them, over time, the humification process significantly intensifies. The data obtained showed that, due to a sharp drop in the volume of use of phosphorus fertilizers, the area of arable land with increased, high and very high provision of mobile forms of phosphorus was only 26.1% of the surveyed 300 hectares, while the area of soil with medium, low and very low content was 73.9%. This indicates the dependence of the content of this form of phosphorus on the application of fertilizers, and given the diversity of farm fields in the content of this element, it is necessary to apply doses of phosphorus fertilizers calculated taking into account the content of phosphorus in the soil strictly according to the cartogram.A relatively favorable situation is observed in terms of the content of exchangeable potassium in the soils of the farm, as evidenced by the rather high gradation of the content of this form of this element. 85.2% of the surveyed area had a high and very high supply of this form of potassium. Consequently, taking into account the state of soil fertility of SPK «Asia Agro Group», a mandatory method that ensures the formation of stable yields is the use of fertilizers, adherence to scientifically based crop rotations, leaving stubble and root residues and other agricultural practices. It must be remembered that as plant residues decompose, the quantitative and qualitative composition of organic substances and nutrients in the soil changes. The chemical composition of decomposing plant residues has a great influence on the accumulation of ammonia and nitrate nitrogen in the soil. The introduction of organic and mineral fertilizers into the soil helps to increase the resistance of crops to adverse environmental factors. This is especially important due to climate change.

Published: December 2024

Abstract. The role of secondary organic aerosol (SOA) in atmospheric ice nucleation is not well understood, limiting accurate predictions of aerosol-indirect effects in global climate simulations. This article details experiments performed to characterize the ice nucleating properties of proxy SOA. Experimental techniques in conditioning aerosol to glass transition temperatures (Tg) as low as -70 °C using a pre-cooling unit are described. Ice nucleation measurements of proxy organosulfates and citric acid were performed using the SPectrometer for Ice Nucleation (SPIN) operating at conditions relevant to upper tropospheric cirrus temperatures (-45 °C, -40 °C, -35 °C) and ice supersaturations (1.0 < Sice < 1.6). Citric acid was used as a control. Methyl, ethyl, and dodecyl organosulfates did not nucleate ice, despite dodecyl organosulfate possessing a Tg higher than ambient temperature. Citric acid nucleated ice heterogeneously at -45 and -40 °C (1.2 < Sice < 1.4), but required pre-cooling temperatures of -70 °C, notably colder than the lowest published Tg. A kinetic flux model was used to numerically estimate water diffusion timescales to verify experimental observations and predict aerosol phase state. Diffusion modeling showed rapid liquefaction of glassy methyl and ethyl organosulfates due to high hygroscopicity, preventing heterogeneous ice nucleation. The modeling results suggest that citric acid nucleated ice heterogeneously via deposition freezing or immersion freezing after surface liquefaction. We conclude that Tg alone is not sufficient in predicting heterogeneous ice formation for proxy SOA using the SPIN.

Abstract. Permafrost landscapes in the Arctic are highly vulnerable to warming, with rapid changes underway. High-resolution remote sensing, especially aerial datasets, offers valuable insights into current permafrost characteristics and thaw dynamics. Here, we present a new dataset of very high resolution orthomosaics, point clouds, and digital surface models that we acquired over permafrost landscapes in northwestern Canada and northern and northwestern Alaska for the purpose of better understanding the impacts of climate change on permafrost landscapes. The imagery was collected with the Modular Aerial Camera System (MACS) during aerial campaigns conducted by the Alfred Wegener Institute in the summers of 2018, 2019, and 2021. The MACS was specifically developed by the German Aerospace Center (DLR) for operation under challenging light conditions in polar environments. It features cameras in the optical and the near-infrared wavelengths with up to a 16 MP resolution. We processed the images to four-band (blue–green–red–near-infrared) orthomosaics and digital surface models with spatial resolutions of 7 to 20 cm as well as 3D point clouds with point densities of up to 41 points m−2. The dataset collection features 102 subprojects from 35 target regions (1.4–161.1 km2 in size). Project sizes range from 4.8 to 336 GB. In total, 3.17 TB were published. The horizontal precision of the datasets is in the range of 1–2 px and vertical precision is better than 0.10 m. The datasets are not radiometrically calibrated. Overall, these very high resolution images and point clouds provide significant opportunities for mapping permafrost landforms and generating detailed training datasets for machine learning, can serve as a baseline for change detection for thermokarst and thermo-erosion processes, and help with upscaling of field measurements to lower-resolution satellite observations. The dataset is available on the PANGAEA repository at https://doi.org/10.1594/PANGAEA.961577 (Rettelbach et al., 2024).

Published: December 2024

This study examined the effects of Accentuated Eccentric Loading Countermovement Jump (AEL CMJ) training on jump performance, lower body strength, sprint performance, and change of direction ability, compared to drop jump (DJ) training. This study used a randomized controlled trial (RCT) with a parallel design. Forty men physical education students (Mean ± SD: age 22.60 ± 3.24 years, body mass 75.21 ± 8.12 kg, height 1.79 ± 0.07 m) were randomly assigned to AEL (n = 14), DJ (n = 13), or a control group (CON, n = 13). The AEL and DJ groups trained three times per week for 8 weeks, while the CON group maintained their usual routines. All groups with similar levels of physical activity outside the training. Pre-, mid- (4 weeks), and post-intervention (8 weeks) assessments measured jump performance (CMJ and squat jump (SJ)), 1RM squat strength, 30 m sprint time, and change of direction (T-test). A mixed-effects model evaluated group and time effects. Significant group × time interactions were observed for CMJ height (P = 0.006), with both AEL and DJ training improving CMJ (AEL: +11.8%, ES = 0.77; DJ: +7.7%, ES = 0.47), SJ height (AEL: +5.7%, ES = 0.37; DJ: +11.3%, ES = 0.66), and 1RM squat (AEL: +7.0%, ES = 0.44; DJ: +8.4%, ES = 0.46) at 8 weeks. Neither training method significantly improved sprint or change of direction performance. Additionally, no significant gains were seen in any indicator at 4 weeks. These results indicate that AEL CMJ and DJ training both effectively enhance vertical jump and strength, positioning AEL CMJ as an effective alternative or complement to DJ training.
Aproximaciones teóricas a las funciones lingüísticas del emoji en comunicaciones digitales: como metáfora, gesto y acotación
Authors: Ferrari Enrique
Published: December 2024

Para una mejor comprensión de la naturaleza lingüística del emoji, se ha explicado su efecto en el texto, al que acompaña en comunicaciones digitales compuestas, a partir de su comparación con otros elementos del lenguaje más estudiados en las discusiones actuales. La primera propuesta, más intuitiva, fue la que lo entendió como metáfora (visual y conceptual), pero obvia diferencias significativas en sus distintos mecanismos, lo que ha hecho que apenas tenga recorrido en la literatura académica. Estudios más recientes han asimilado su función a la del gesto, como lenguaje no verbal. Sin embargo, no hay todavía investigaciones sobre sus condiciones específicas como código escrito, en tanto que transcripción de ese gesto en una comunicación que no es oral. Dado ese obstáculo, este trabajo propone entender el emoji con una tercera comparación: como la representación visual que marca, más que el gesto mismo, su ausencia, para poner en alerta al interlocutor, que debe imaginarlo o suponerlo en el contexto de la oralidad: como las acotaciones en teatro.
¿Palabras contra la sensibilidad burguesa? Análisis lexicométrico de los manifiestos de arte del siglo XX
Authors: Luna Diego
Published: December 2024

El análisis crítico de los discursos verbales constituye una estrategia especialmente útil para comprender la manera en que los manifiestos de arte intentan desafiar determinadas narrativas, inaugurar otras realidades y construir una identidad propia. El presente estudio partió de la necesidad de seguir profundizando en el conocimiento de los manifiestos artísticos del siglo XX, asumiendo como principal objetivo la exploración de la evolución del potencial político del arte en los manifiestos modernos y posmodernos desde un enfoque lexicométrico. Los resultados obtenidos revelan una progresiva despolitización de los discursos artísticos recogidos en este tipo de escritos: si, por un lado, los manifiestos modernos dedican grandes esfuerzos a atacar la sensibilidad burguesa y todo lo que ella representa, por otro, los textos posmodernos olvidan por completo los objetivos antiburgueses y parecen centrarse en reflexionar sobre un sistema ya consolidado, el del arte, sin amenazar en ningún momento su existencia.
A fossil proof for the origin of the Hirnantian glaciomarine record in Bulgaria: A preliminary result
Authors: Sachanski Valeri , Gutiérrez-Marco Juan Carlos , Georgiev Stoyan , Lakova Iskra , Yanev Slavcho
Published: December 2024

The Sirman Formation in the Svoge Unit is built of Hirnantian diamictites, a product of the Gondwana glaciation at the end of the Ordovician. One subangular lonestone of light gray sandstone of size of about 1 cm was found in the lower part of the formation. This pebble, interpreted as a glacial dropstone, contain a relatively well-preserved external negative mould of a trilobite pygidium, which has tentatively been identified as Dreyfussina cf. libyca in absence of cephalic characters. The nominal species was described from the Melaz Shuqran Formation of Libya (Al Qarqaf Arch). The present record supports an African origin for pebbles transported by floating ice to the sediments of the Svoge Unit, consistent with provenance data – the Trans-Saharan Belt, derived from the detrital zircons recorded on the same Hirnantian diamictites in Bulgaria.

Published: December 2024

В работе исследуется процесс лазерного легирования алюминия и сплава АЛ25 металлами: никелем, хромом, ниобием в режиме оплавления. Выбор металлов для исследования выполнен по критерию степени заполнения зон расплава при лазерном воздействии. Проведен теоретический анализ возможных интерметаллидных фаз в системах Al–Ni, Al–Cr, Al–Nb, их физических параметров и кристаллографических характеристик. Экспериментальные исследования методами металлографии и рентгеноструктурного анализа позволили установить спектр фаз, формирующихся при легировании алюминия порошками этих элементов. К ним относятся как интерметаллиды, богатые алюминием, так и химические соединения, обогащенные легирующим металлом. Исследовано также легирование дисилицидом ниобия для установления различий в механизмах введения химических соединений в зону лазерного воздействия. При легировании NbSi2 частицы попадают в зону расплава непосредственно из порошка (механизм «влета» частиц), а при легировании чистым металлом образование интерметаллидов происходит in situ в процессе кристаллизации. На основе расчета изменения периода решетки алюминия произведена оценка концентраций легирующих металлов в пересыщенном твердом растворе. Установлено повышение микротвердости зон легирования, обусловленное твердорастворным упрочнением и дисперсионным упрочнением частицами интерметаллидов.

The paper studies the process of laser alloying of aluminum and alloy AL25 with metals: nickel, chromium, niobium, in the melting mode. The choice of metals for the study is made according to the criterion of efficiency of melt zone filling under laser treatment. Theoretical analysis of possible intermetallic phases in Al–Ni, Al–Cr, Al–Nb systems was carried out, including their physical parameters and crystallographic characteristics. Experimental studies by methods of metallography and X-ray diffraction analysis allowed establishing the spectrum of phases formed during alloying of aluminum from powders of these elements. They include both aluminum-rich intermetallics, and chemical compounds enriched with the alloying metal. Alloying with niobium disilicide is also investigated to reveal differences in the mechanisms of introducing chemical compounds into the laser-affected zone. When alloying with NbSi2 particles get into the melt zone directly from the powder (the mechanism of «flying in» particles), and when alloying with pure metal the formation of intermetallics occurs in situ during the crystallization. On the basis of calculation on the change of the lattice period of aluminum the concentrations of alloying metals in the supersaturated solid solution were estimated. The increase in microhardness of alloying zones due to solid solution hardening and dispersion strengthening by intermetallide particles has been established.

Giovanni Maria Mosca (Called Padovano) and Giovanni Jacopo Caraglio. A Revision of the Oeuvre of Italian Medallists at the Court of the Last Jagiellons
Authors: Smołucha-Sładkowska Agnieszka
Published: December 2024

The article presents new findings and arguments on the attribution of a group of medals produced during the reign of the last Polish kings from the Jagiellonian dynasty – Sigismund I the Old and Sigismund II Augustus. These medals were created in the first half of the 16th century at the courts in Krakow and Vilnius by two artists who came from Italy – Giovanni Maria Mosca (called Padovano) and Giovanni Jacopo Caraglio. The artists had different artistic formations, and they work differ significantly from each other in both technique and style. Mosca’s and Caraglio’s medals, being among the oldest medallic portraits of Polish kings, were frequently copied for the needs of collectors over the following centuries; only a small number of originals are known. The author revises known specimens of the Padovano medals and, in the case of Caraglio’s medallic oeuvre, rejects the attribution of some of the works made to this artist.

Multi-environment automotive QOS prediction using Machine Learning for Vehicle-to-Anything (V2X) communications
Authors: Sengayo Ndabuye , Basikolo Thomas
Published: December 2024

The advent of 5th Generation (5G) wireless systems has ushered in a new era of vehicular applications, where reliability and low latency are paramount. This evolution is expected to continue with the transition to 6G and beyond, heavily relying on Machine Learning (ML) to make proactive decisions and manage the Quality of Service (QoS) for an enhanced user experience. Particularly in vehicular communications, the Vehicle-to-Everything (V2X) schemes stand to gain immensely from these technological advancements. In this study, we explore this cutting-edge domain and propose LightGBM-enhanced MLP (LeMLP), a lightweight and effective ML approach focusing on the prediction of QoS in V2X communications using LightGBM and Multilayer Perceptron (MLP), a critical component for the safety and efficiency of autonomous vehicles. Our methodology builds upon the Berlin V2X dataset, encompassing diverse urban environments' data sources, including GPS, ping, iperf, and LTE. In our proposed technique, the model is trained on data from one mobile network operator and then evaluated on data from another (multi-domain approach), reflecting real-world scenarios of varying network conditions. Through this multi-domain adaptation approach, LightGBM's split method, and fine tuning, we achieved an R2 score of 0.9447 on evaluation using only six key features. This improvement is significant in the context of 5G communication systems, where the prediction and early notification of QoS changes can profoundly impact the operational safety of autonomous vehicles. This research not only contributes to the technical advancement in vehicular networks but also opens avenues for exploring various data, feature selection strategies, and prediction qualities. It lays a solid foundation for deploying robust ML models in real-world scenarios, thereby advancing the capabilities of V2X communications in the era of 5G and beyond.

Published: December 2024

Inheriting and carrying forward the excellent traditional Chinese culture is an important part of improving the soft power of national culture. Intangible cultural heritage is an important part of the excellent traditional Chinese culture. Traditional culture in the new era wants to pass on a long time and cannot be separated from the creative transformation and innovative development. Nowadays, the phenomenon of “Breaking the Circle” communication of intangible cultural heritage is frequent, breaking through the circle of mainstream culture and youth groups, opening up a new space for the dissemination, transformation, and innovation of traditional culture. However, how to “break,” why to “break” and the enlightenment brought by the phenomenon of “Breaking the Circle” for the dissemination of intangible cultural heritage are all worthy of in-depth consideration. This paper takes immersion theory as the starting point, supplemented by relevant theories in media science, and summarizes the three major rules of the “Breaking the Circle” phenomenon: immersion communication, multimodal experience, and cross-border integration. It analyzes the causes and revelations of the phenomenon of “Breaking the Circle” of intangible cultural heritage, in order to better play the role of Flow Experience in the inheritance and dissemination of outstanding Chinese traditional culture.
Çin Halk Cumhuriyeti, Amerika Birleşik Devletleri ve Avrupa Birliği’nin İklim Rejimi Politikalarının Karşılaştırılması
Authors: Kara Eray
Published: December 2024

İklim rejimine ilişkin politikaların gelişim sürecinde ülkelerin aldıkları roller, bu ülkelerdeki politika yapıcıların kısa vadeli kararları ve ülkelerin genel siyasi eğilimlerine göre değişmektedir. Bu ülkeler arasında dünyanın üç ekonomik büyük gücü olan; Çin Halk Cumhuriyeti, Amerika Birleşik Devletleri ve Avrupa Birliği’nin geliştirmiş olduğu politikalar, iklim rejiminin uygulanabilirliği açısından hayati bir role sahiptir. İklim rejimi konusunda öncü role sahip olan Avrupa Birliği, politikaların geliştirilmesi ve uygulanması konusunda ortak hareket etmektedir. Bu nedenle; politikaların karşılaştırmalı analizini içeren bu çalışmada Avrupa Birliği bir bütün olarak ele alınmaktadır. Bu çalışma, üç ülkenin iş birliği ve rekabete dayalı politikalarının iklim rejiminin geleceğini belirleyeceğini varsayarak, ülkelerin süreç içerisinde atmış olduğu adımların değerlendirilmesi amaçlanmaktadır. Çalışmada uluslararası örgütlerin ve ülkelerin almış olduğu kararlar, istatistik kurumları ve çevre ajanslarının veri tabanları, çeşitli raporlar ve konuya ilişkin incelenen diğer ikincil veriler kullanılmıştır. Bu veriler ışığında varılan sonuç ise, bu üç ülkenin aldığı kararların ve uyguladıkları politikaların iklim krizi ile mücadele konusunda belirleyici olduğudur. Rekabet ve iş birliğine dayanan bu süreç içerisinde; her üç ülkede zaman zaman birbiriyle yakın ilişkiler geliştirmekte ya da çeşitli çatışmalar yaşamaktadır. Dünyanın çeşitli bölgelerinde yaşanan çatışmaların gölgesinde Bakü’de düzenlenecek COP29 ve devamında gelen süreçte bu üç ülkenin iklim krizini ciddiyetle ele alması elzemdir. Ancak Amerika Birleşik Devletlerinde yapılacak başkanlık seçimlerinde ortaya çıkabilecek sonuçlar, Avrupa’da yükselen sağ-popülist politikacılar nedeniyle Birliğin zayıflaması ve Çin Halk Cumhuriyeti’nin Tayvan sorununun önceliklendirilmeye başlayarak savaş ekonomisine geçmeye hazırlanması gibi meseleler nedeniyle iklim rejiminin konusunda karamsar bir tablo da çizilebilmektedir.

Authors: K Zhou , Faraz Crossville Aniqa , M Hendrixson
Published: December 2024

Pancreatic mixed acinar-neuroendocrine carcinoma (pMANEC) is an extremely rare malignancy with both acinar carcinomas with neuroendocrine lineage differentiations. Herein, we present a case of pMANEC in a 78-year-old male who initially presented to the clinic for night sweats, easy bruising, and lumbar pain, leading to the discovery of a pancreatic mass on imaging. Pathological examinations, including immunohistochemistry, confirmed the diagnosis of possible pMANEC, characterized by acinar and neuroendocrine differentiation. Further diagnostic workup with DOTATATE NM positron emission tomography/computed tomography (PET/CT) scan provided additional insights, confirming the neuroendocrine nature of the tumor. The patient was started on gemcitabine and nab-paclitaxel every other week and also started on lanreotide for treatment. Our case highlights the challenges in diagnosing and managing this rare entity and underscores the need for further research to explore its clinical behavior, molecular characteristics, and optimal therapeutic strategies. Additionally, the potential role of genetic profiling and immunotherapy in improving outcomes for patients with pMANEC warrants investigation.
„Liūdnas ir gražus pasaulis“ Jimo Jarmuscho filmuose: kalbos problemos ir poezija kaip (ne)pereinamas tiltas į kitybę
Authors: Kazakevičiūtė Evelina
Published: December 2024

The article argues that Jim Jarmusch’s films can be regarded as cinematographic poetry and the director himself – as a cinematic poet. The author analyses the themes
recurring in Jarmusch’s films: problems of language, poetry, and otherness. Developing them, Jarmusch reveals the stylistic peculiarities of his creative work: the usage of
different languages, puns, polysemy, etc. These elements, as it is stated in the study,
make Jarmusch’s creative work poetic. Special attention is paid to the relationship between the spoken and the written word and the significance of poetry for Jarmusch’s
films as well as their representation in them. It is demonstrated that the director
problematizes language, presenting the advantages and disadvantages as well as the
similarities and differences of speech and writing, and thus giving a subtle critique of
metaphysical thinking and logocentrism. As the review and the analysis of two Jarmusch’s films, Down by Law (1986) and Dead Man (1995), show, poetry is what, on
one hand, divides the foreigner and the natives, however, on the other hand, despite
the untranslatability of it, the barriers of language, culture, and communication, poetry also unites them. The figure of a foreigner shows up as essential for the identity
of the locals. At first, the other looks strange and even antagonizing to them, and it is
difficult for them all to communicate, but eventually, they manage to establish a good
relationship – through language and poetry that is foreign to the foreigner. Reminding
the locals about their cultural signs, translating and interpreting them, the foreigner
brings the element of otherness into them, thus renewing, changing, and strengthening those signs as well as the identity of the locals. The author concludes that the journey and the experiences of a foreigner presented in Julia Kristeva’s book Strangers to
Ourselves(1991) can be noticed in Jarmusch’s films. It is argued that, just as Kristeva’s
theoretical work, Jarmusch’s creative work encourages us to accept otherness as part
of our own identity. Also, they encourage us to investigate the signs of own and other
culture(s) as diversely as possible and translate and interpret them as freely as possible. Perhaps the exact translation and the ‘right’ interpretation are not always possible, but translation and interpretation are necessary – they can enrich these signs, just
as the encounter with a foreigner can enrich our identity.
Meninio aktyvizmo įmuziejinimas. Arba kritika kaip ekspozicijos objektas
Authors: Trilupaitytė Skaidra
Published: December 2024

The text focuses on the shape of social and artistic activism in the discourse deployed
by contemporary museum. Taking into account the theoretical approach of Boris
Groys on art activism, along the differences he noticed between contemporary activism and the artistic criticism of the late seventies, the article discusses how artistic
protests and forms of opposition become important aspect of the institutional identity. First, the attempt is made to clarify the notions of artistic protests in regard of
Fluxus movement in Lithuania. Second, the article shows that political consensus in
neoliberal Vilnius urban policy was also shaped by Fluxus brand, when new luxurious real estate development embraced the rhetoric about the grand new Guggenheim
museum. Third, there are examples from Fluxus historical exhibitions in Lithuania
and Fluxus items in the museum that reflect ambivalent trajectories in interpreting
this „Lithuanian“ phenomenon. Finally, one may notice only one consistent oppositionist and radical activist of contemporary Lithuanian art – the scandalous artist
Redas Diržys from Alytus, who consciously distance himself from the „art of capital“.
In turn, the most memorable artistic actions of urban protest in capital city (Vilnius)
took place in 2005 next to foreclosed movie theatre „Lietuva“, where the protest laboratory was established and activists protested against shady privatization of public
space. Lots of events in the latter case were initiated by protest artists couple Nomeda and Gediminas Urbonas whose works eventually were accepted in the museum
space (example of MO) and even where placed at the Center for Civic Education (established at the Presidential Palace). One could conclude that on the one hand, Fluxus
acquired neutral meaning in the museum. On the other hand, in some cases, Fluxus
still has the potential of artistic radicalism when contemporary artists are trying to
address issues concerning real city policies.
Baronas ir baronienė Ernstas ir Jekaterina von der Osten-Sacken - kultūrinio gyvenimo Vilniuje dalyviai (XIX a. antroji pusė)
Authors: Bakutytė Vida
Published: December 2024

In this article the author takes a look at the couple of Russian noble intellectuals - Baron Ernst von der Osten-Sacken (1841/1846-1911), a descendant from the Germans o f Courland, and Baroness Ekaterina von der Osten-Sacken (1845/1846-1923), who lived in Vilnius in the 2nd half of the 19th century. Their life and cultural activities in Vilnius (1874-1892) can be considered as a characteristic phenomenon of the epoch: husband, who was appointed to a high-ranking post in the public service in Vilnius, and his wife accompanying him, who was a singer, amateur composer, poetess and writer, got actively involved in musical, theatrical and literary life o f the city by simultaneously maintaining their previous connections with prominent cultural figures, well-known writers, musicians, poets, individuals of the upper social class and in this way linking the Lithuanian cultural movement with equivalent phenomena in the hubs of the Russian Empire. The involvement of Ernst and Ekaterina in the activities o f cultural societies and concert life, their engagement in educational and charitable work, literary initiatives, reviews of musical and theatrical events, etc. contributed to the growth in the quality of the city's cultural life: lacking in quality as the outcome of long-term repressive measures of political censorship imposed by the tsarist rule in the 1860s was also sensed in the 1870s. While remaining at the margins of this article, there is an other historical noteworthy circumstance - Natalie Charlotte Chodakowska (born von der Osten-Sacken, 1819-1903) was grandmother to Sofija Chodakauskaitė-Smetonienė - the spouse of Lithuanian President Antanas Smetona, was also a descendant of the same von der Osten-Sacken family of German barons from Courland (it is likely from other family line).

Aromatherapeutic Remedies to Ease The Work Related Stress
Authors: Altıntaş Gündüz Dudu , Koca Çalışkan Ufuk
Published: December 2024

Stress is defined by WHO (World Health Organization) as a state of worry or mental tension caused by a difficult situation. Stress is a natural human response to address challenges and threats in our lives. Although everyone experiences stress at some levels, the way we respond to stress makes a big difference to our well-being.. Given that individuals spend the majority of their time at work, managing work-related stress is of significant importance for the quality of life of the individual. There are numerous approaches for the stress management, including synthetic drugs, aromatherapy and massage applications. Since the aromatherapy is notable for its straightforward applicability and reliability, the efficacy of aromatherapeutic applications in managing work-related stress was evaluated
Visuospatial agraphia due to the right parietal lobe infarction: a case report
Authors: Heo Woon Chang , Lee Seung Hyun
Published: December 2024

Agraphia is an impairment or loss of a previous ability to write. In general, injury of the dominant hemisphere leads to agraphia. However, we report a case in which the patient presented with visuospatial agraphia due to right parietal lobe infarction. A 65-year-old man was admitted with left-sided weakness and paresthesia. Signs of neglect syndrome were also observed in neurological examination. A brain magnetic resonance imaging showed acute infarction in the right parietal lobe. After hospitalization, the patient complained of an inability to write unlike before. Neuropsychological testing revealed no abnormalities in the language domain, but deteriorations in visuospatial, memory, and frontal/executive function. In particular, the patient had difficulty with the Rey Complex Figure Copy task. His writing disability showed features of visuospatial agraphia. Our case suggests that the injury of the right parietal lobe can cause agraphia due to impairment of visuospatial/constructional function.

In fracture mechanics, the problem of crack propagation is an important phenomenon in fracture mechanics. Currently, it is very difficult to avoid this phenomenon, but there are possibilities to reduce it. In fact, the parameters for characterizing the fracture state today can play important roles, especially at the fracture interface level. This paper deals with the numerical modeling of the effect of distance (l) and hole diameter on the variation of crack parameters such as stress intensity factors (KI and KII), circumferential integral J and internal energy (ALLIE) for a model containing a crack and a hole located in the same line of the initial crack at distance (l), for the cracked model containing a hole with diameter d = 0.1, 0.2 and 0.5 mm, located in front of the crack at length l = 1.5, 2, 3 and 3.5 mm. The finite element method (FEM) was used. In addition, four-node elements (CPS4R) were used. On the other hand, a good agreement was also obtained between the different results of the comparisons regarding the evolution of different crack parameters in all the modeling cases we considered. The stress intensity factors (KI and KII), contour integral J and internal energy (ALLIE) are calculated using the ABAQUS finite element code.

Published: December 2024

Brain tumors are highly complex and diverse, making early diagnosis crucial for effective treatment and improved patient outcomes. Artificial Intelligence (AI) has emerged as a powerful tool to address the challenges of traditional diagnostic methods, which often rely on labor-intensive and error-prone manual analysis by radiologists and neurologists. Recent advancements in deep learning enable automated and accurate classification of brain tumors, significantly enhancing diagnostic efficiency and reliability. This study focuses on a deep learning-based approach that utilizes expert-labeled MRI scans to classify brain conditions into four categories: pituitary tumor, glioma, meningioma, and healthy. By automating tumor classification, this method reduces diagnostic workload and ensures consistent results. The integration of such AI-driven systems into clinical workflows has the potential to revolutionize brain tumor detection, enabling earlier intervention and more personalized treatment strategies. This work highlights the transformative role of AI in advancing medical imaging and improving patient care.
