Nut graphs with a prescribed number of vertex and edge orbits
No full textA nut graph is a nontrivial graph whose adjacency matrix has a one-dimensional null space spanned by a vector without zero entries. Recently, it was shown that a nut graph has more edge orbits than vertex orbits. It was also shown that for any even and any , there exist infinitely many nut graphs with r vertex orbits and k edge orbits. Here, we extend this result by finding all the pairs for which there exists a nut graph with vertex orbits and edge orbits. In particular, we show that for any , there are infinitely many Cayley nut graphs with edge orbits and arc orbits
Informacijska in komunikacijska tehnologija ter finančni razvoj kot katalizatorja za enakost spolov v brazilskem kmetijskem sektorju
No full textIn this study, we examined the effects of information and communications technology (ICT) and financial development on mitigating gender inequality in Brazil, using autoregressive distributed lag (ARDL) approaches, between 1991 and 2022. The ARDL bounds test was employed to find the presence of co-integration within the series of data. Both in the short run and the long run, financial development has a significant negative impact on gender disparitythis means that policies aimed at enhancing women’s financial and consumption services should be promoted in the short run. In the long run, we can conclude that ICT developments lead to a decreasein gender inequalities, which may imply the need for strategic, long-term planning to increase ICT infrastructure, especially in deprived areas. This includes subsidising affordable internet, skills training for women in the ICT field, and promoting women’s participation in the technology industry. In addition, the impact of optimal financial development varies over timehence, there is a need for flexibility and sustainability in financial development. Policy makers should therefore continue to strengthen and enhance financial inclusion initiatives, as well as regularly follow up on the impact of these initiatives on gender equality.V tej raziskavi smo preučevali učinke informacijske in komunikacijske tehnologije (IKT) ter finančnega razvoja na zmanjševanje neenakosti med spoloma v Braziliji, z uporabo pristopov z avtoregresivnim porazdeljenim zamikom (angl. autoregressive distributed lag – ARDL) v obdobju med letoma 1991 in 2022. Uporabljen je bil ARDL-test mejnih vrednosti za ugotavljanje prisotnosti kointegracije v podatkovnih serijah. Tako na kratki kot na dolgi rok ima finančni razvoj pomemben negativni vpliv na razlike med spolomato pomeni, da je treba na kratki rok spodbujati politike, usmerjene v izboljšanje finančnih in potrošniških storitev za ženske. Na dolgi rok lahko zaključimo, da razvoj IKT vodi k zmanjšanju neenakosti med spoloma, kar lahko pomeni potrebo po strateškem, dolgoročnem načrtovanju za povečanje IKT-infrastrukture, zlasti na prikrajšanih območjih. To vključuje subvencioniranje dostopnega interneta, usposabljanje žensk za veščine na področju IKT ter spodbujanje njihove udeležbe v tehnološki industriji. Poleg tega se vpliv optimalnega finančnega razvoja s časom spreminjazato sta pri finančnem razvoju potrebni fleksibilnost in trajnostnost. Odločevalci bi morali tako še naprej krepiti in izboljševati pobude za finančno vključenost ter redno spremljati vpliv teh pobud na enakost spolov
Kritični položaj sovjetskih parlamentarnih stavb danes
No full textNationalist discourses build societal unity by shaping rituals, historical narratives, and collective memory to construct the myth of a nation. Post-Soviet countries offer a unique context for examining the production of nationalism as a transition from a multinational past to a national identity. This process of decommunisation unfolds through the Soviet traces in the built environment. As a physical representation of the state narrative, we focus on the architectural memory and architectonic transformations of Soviet parliament buildings, analysed via large-scale axonometric drawings. Architectural landmarks such as parliament areas have evolved into focal points for confronting the traumatic memory of the second half of the twentieth century. The text focuses on the White House in Moscow, the Verkhovna Rada in Kyiv, the Government House in Baku, the National Assembly Building of Armenia in Yerevan, and the Government House in Minsk. How have communities reacted to the parliament buildings as tangible reminders of their problematic past? Following the methodologies the forensic aesthetic paradigm opened up, we traced the protest’s morphology, its form, and the transformations made in the built environment. By analysing videos, photos, and newspaper articles, we mapped out the protests to discuss architecture’s role in conveying state narratives.Nacionalistični diskurzi gradijo družbeno enotnost z oblikovanjem ritualov, zgodovinskih pripovedi in kolektivnega spomina, da bi ustvarili mit o narodu. Postsovjetske države ponujajo edinstven kontekst za preučevanje nastajanja nacionalizma kot prehoda od večnacionalne preteklosti k nacionalni identiteti. Ta proces dekomunizacije se odvija skozi sovjetske sledi v grajenem okolju. Kot fizično predstavitev državnega narativa se osredotočamo na arhitekturni spomin in arhitektonske preobrazbe sovjetskih parlamentarnih stavb, analiziranih preko velikih aksonometričnih risb. Arhitekturne znamenitosti, kot so parlamentarne površine, so se razvile v osrednje točke za soočanje s travmatičnim spominom na drugo polovico 20. stoletja. Besedilo se osredotoča na Belo hišo v Moskvi, Vrhovno rado v Kijevu, vladno palačo v Bakuju, stavbo nacionalne skupščine Armenije v Erevanu in vladno palačo v Minsku. Kako so se skupnosti odzvale na parlamentne stavbe kot oprijemljive spomine na svojo problematično preteklost? V skladu z metodologijami, ki jih je odprla forenzična estetska paradigma, smo sledili morfologiji protestov, njihovi obliki in spremembam v grajenem okolju. Z analizo videov, fotografij in časopisnih člankov smo naredili zemljevid protestov, da bi razpravljali o vlogi arhitekture pri posredovanju državnih narativov
From permits to samples
No full textHigh-quality reference genome assemblies have become essential for deepening our understanding of biodiversity, yet obtaining them for many species remains surprisingly challenging. Drawing on experiences from the European Reference Genome Atlas (ERGA) community, we focus on permit and sample-handling procedures leading up to nucleic acid sequencing, covering tasks such as ensuring ethical and legal compliance, verifying accurate species identification, maintaining sample integrity during transport, and isolating high-quality DNA or nuclei. While many of the challenges and solutions we discuss are broadly relevant, our regulatory and logistical examples are primarily from Europe. By synthesising practical guidance, we highlight the crucial importance of taxonomic expertise, proper vouchering and biobanking, rigorous cold-chain management or alternative preservation methods, and emphasise adherence to packaging and shipping requirements for biological materials. We showcase examples spanning diverse regions, taxa and source materials, which underscore the importance of context-specific strategies and internationally harmonised protocols, particularly for metadata reporting. Our recommendations aim to support both small-scale projects and large initiatives, directing collective efforts to facilitate efficient sampling, vouchering and sample processing for future genomic studies
Translation of Situation Awareness Rating Technique Questionnaire in Slovenian
No full textThe Situational Awareness Rating Technique (SART) is a questionnaire designed to assess situational awareness when operating a machine. It consists of ten questions corresponding to ten dimensions that can be used to assess an operatorǯs situational awareness when interacting with and operating a machine. Although initially developed for assessment situational awareness of pilots, with the rising complexity of vehicles and introduction of automation, its use has spread significantly in automotive domain in the past decade. In this paper, we present the Slovenian version of the original questionnaire and the process of its development. For the translation of the questionnaire SART into Slovenian, the standard procedures for the translation of research instruments were applied: translation, coordination, back-translation into the source language, comparison of the back-translation with the source text and final coordination. Lastly, it was validated against a reference system in a driving-based environment
Implementation of the Science on a Sphere Visualization System as a Web Application
No full textSOS is a visualization system originally developed by the U.S. National Oceanic and Atmospheric Administration National Oceanic and Atmospheric Administration (NOAA) to project dynamic global datasets onto a spherical display, enabling audiences to explore complex Earth system processes in an intuitive and immersive way. While highly efective in museums, science centers, and classrooms, the traditional Science on a Sphere (SoS) hardware installation requires dedicated infrastructure, limiting its accessibility and scalability. This paper presents the design and implementation of a web-based application that reproduces the core functionality of the Science on a Sphere (SoS) system in a browser environment. The application utilizes modern web technologies to render real-time spherical visualizations of global datasets. Users can load, manipulate, and interact with datasets such as atmospheric phenomena, ocean currents, or planetary imagery without the need for specialized hardware. The system also supports interactive controls for rotating, zooming, and overlaying multiple data layers, extending the pedagogical potential of Science on a Sphere (SoS) by enabling personal exploration on laptops, tablets, and mobile devices. By transitioning Science on a Sphere (SoS) from a physical installation to a lightweight, browser-based platform, the proposed solution broadens access to scientific visualizations, promotes remote and classroom learning, and ensures that Science on a Sphere (SoS) content can be integrated into modern online education ecosystems
