Energy efficiency is inherent for autonomous robotic device. Snakes are well known for their ability to low energy consumption when swimming. However, the swimming know-how is poorly understood. Designing a snake robot inspired by snakes as a tool to find out the swimming energy efficiency crucial point will lead to the development of hyper efficient undulating locomotors. In this article, we introduce a four tendons driven continuum robot made of bio-inspired compliant vertebrae to assess the energy consumption of a planar and a spatial snake motion. The tendon-driven continuum robot constitutes the head–neck part of a locomotor snake robot. A static modeling coupled with an optimization method was implemented to generate bio-inspired motions recorded on snake swimming head. A friction model describing the friction between cables and the disks is investigated and compared to a frictionless model. The proposed prototype is equipped with exteroceptive sensors to record motion and proprioceptive sensors to measure cable forces applied at the tip of the robot. Hence, the work of the forces, thus the energy required to execute a trajectory are computed and analyzed. The energy is introduced as a key criterion to assess the swimming motion of a locomotor snake robot.

Given the varying degrees of importance that a holy place holds for different parties and the variety of laws used to regulate them, laws pertaining to holy places integrate a broad array of legal, political, social, religious, and economic interests. Acknowledging the difficulty of capturing a singular standard of protection merits examining different existing modalities to discern the means of protection for holy places.

A 2022 Israeli District Court case concerning ownership rights over a Russian Orthodox church in the Old City of Jerusalem shall provide the platform for scrutinizing the relevant laws and variety of interests at play for holy places in Israel, providing insights into the importance of accounting for divergent interests in the cultural heritage protection milieu. This article shall highlight the approaches used towards holy place protection in a difficult and complex context, Israel, to better understand heritage protection methods for unique or significant cultural sites in other regions.

While there is literature on ‘populist securitisation’ and on the ‘securitisation of Islam’, the possibility that some populists may desecuritise Islam is not sufficiently explored. Left-wing populist parties have demonstrated solidarity towards Muslim minorities in Europe through a discourse based on inclusionary rhetoric and deconstruction of the securitising narratives promoted by mainstream and populist right-wing parties. However, their attitude towards Islam can be ambiguous. This paper argues that left-wing populists tend to desecuritise Islam. However, desecuritisation happens in ways that do not always accommodate Muslims’ religious freedoms. This happens because the driver of the left-wing populist desecuritisation of Islam lies in the left-wing thick ideology surrounding populism and not in the populist thin core. I illustrate this argument through the case study of Jean-Luc Mélenchon, leader of the left-wing populist party La France Insoumise. Through a discourse analysis of texts from 2009 to 2022, I show that Mélenchon has predominantly desecuritised Islam. While his desecuritisation is populist, it has not been truly emancipatory for Muslims. Although a more committed fight against Islamophobia has emerged since 2019, Mélenchon’s ideological attachment to laïcité hinders a full rearticulation of French political community based on genuine recognition of Muslims’ religious freedoms.

We challenge Binz et al.'s claim of meta-learned model superiority over Bayesian inference for large world problems. While comparing Bayesian priors to model-training decisions, we question meta-learning feature exclusivity. We assert no special justification for rational Bayesian solutions to large world problems, advocating exploring diverse theoretical frameworks beyond rational analysis of cognition for research advancement.

Chinese characters hold great potential to help inform and enrich psycholinguistic research on lexical ambiguity as a large portion of them are ambiguous in nature with meaning varying from context to context. This report presents a psycholinguistic database that contains over 2000 characters with normative measures for meaning dominance and meaning balance, that is, the relative frequency of each meaning associated with a target character and the degree of balance across the meanings of the character. The measurement process takes advantage of the fact that, in Chinese, generating words containing a target character is the most convenient way to specify and disambiguate character meanings. Character meanings stored in ordinary people’s mental lexicon are identified based on the words, along with a small portion of meaning descriptions, listed by over 900 native speakers. The measures of meaning dominance and meaning balance for the characters are derived from computing the relative frequencies of the meanings. Potential research and practical applications of the database, as a valuable tool, to enhance our understanding of the acquisition, representation, and processing of ambiguous lexical items are discussed.

Conservation agriculture plays an important role in the sustainability of production systems, notably for globally significant crops such as cotton. This study explores the integration of the no-tillage system (NTS) with integrated pest management (IPM) by incorporating cover crops. The aim is to assess the impact of these living or dead covers on the management of insect populations, the indices diversity of phytophagous insects and natural enemies, and to investigate the population fluctuation of these arthropods, considering a variety of crops in the NTS before and after cotton planting. The trial, conducted over two consecutive cropping seasons in Mato Grosso do Sul State, Brazil, employed a randomised block design with four repetitions. The treatments included cover crops with the highest potential for use in the region, such as millet (Pennisetum glaucum glaucum L.), corn (Zea mays L.), brachiaria (Urochloa ruziziensis), black velvet bean (Stizolobium aterrimum), forage sorghum (Sorghum bicolor L.), and white oats (Avena sativa L.) and a mix of white oats with brachiaria. The results indicated that the black velvet bean stands out as the most effective cover crop, providing the best performance in terms of non-preference to the attack of the evaluated pest insects. Conversely, brachiaria proves to be more susceptible to infestations of Dalbulus maidis (DeLong and Wolcott) (Hemiptera: Cicadellidae), and Diabrotica speciosa (Germar, 1824) (Coleoptera: Chrysomelidae). The study underscores the relevance of the judicious choice of cover crops in IPM and in promoting agricultural biodiversity, creating a strategic tool to enhance the sustainability and efficiency of the cotton production system in the context of the NTS.

Six different types of Majiang bronze drums from Hechi City, Guangxi, China were collected from the Guangxi Museum to characterize the original scheme of polychromy and materials used for the drums. The composition of all the samples were determined by using scanning electron microscopy with energy-dispersive X-ray spectroscopy. All the bronze drums contain mainly Cu, Sn, Pb, and As. Qualitative analysis of the structure by X-ray powder diffraction indicates that each of the six bronze drums contains four or five phases, namely (Cu, As), Pb, Cu3Sn, and Cu10Sn3 or Cu, Pb, As0.2Cu1.8, Cu3Sn, and Cu10Sn3. The Rietveld structural refinement is performed first time for the quantitative analysis of ancient bronze drums and inorganic cultural relics. This paper reports the result.

Dietary surveys are critical in evaluating dietary trends prevailing across the entire population. The aim of this study is to present the results of the latest research into the intakes of energy, macronutrients, and micronutrients amongst the adult population in Lithuania from 2019 through 2020. A cross-sectional study was conducted and dietary data was collected using a 24-h dietary recall method from a total of 2555 Lithuanian adults. Medians, 25th and 75th percentiles were calculated. The diet of Lithuanian adults was found insufficient as the energy intake from fats exceeded the recommended norms, while the energy intake from carbohydrates was below the lower range. The intakes of dietary fibre and most vitamins and minerals were insufficient. Men, compared to women, had a statistically higher total energy intake and energy intake from fats, and a higher intake of dietary fibre. Younger adults, compared to older ones, had statistically lower intakes of energy from fats, including saturated fats, and lower intakes of sodium chloride. Respondents with primary education, compared to those who had attained a higher degree of education, had a statistically lower intake of total energy and dietary fibre. Study showed that intakes of majority of nutrients in the diet of the adult Lithuanian population are not in compliance with the recommended daily intakes. Continuous nationally representative studies into food consumption and nutrient intake of the adult Lithuanian population must be carried out to assess the changes in the population’s diet and the effectiveness of policies aimed at promoting healthy diets.

Global warming is exposing many organisms to severe thermal conditions and is having impacts at multiple levels of biological organisation, from individuals to species and beyond. Biotic and abiotic factors can influence organismal thermal tolerance, shaping responses to climate change. In eusocial ants, thermal tolerance can be measured at the colony level (among workers within colonies), the population level (among colonies within species), and the community level (among species). We analysed critical thermal maxima (CTmax) across these three levels for ants in a semiarid region of northeastern Brazil. We examined the individual and combined effects of phylogeny, body size (BS), and nesting microhabitat on community-level CTmax and the individual effects of BS on population- and colony-level CTmax. We sampled 1864 workers from 99 ant colonies across 47 species, for which we characterised CTmax, nesting microhabitat, BS, and phylogenetic history. Among species, CTmax ranged from 39.3 to 49.7°C, and community-level differences were best explained by phylogeny and BS. For more than half of the species, CTmax differed significantly among colonies in a way that was not explained by BS. Notably, there was almost as much variability in CTmax within colonies as within the entire community. Monomorphic and polymorphic species exhibited similar levels of CTmax variability within colonies, a pattern not always explained by BS. This vital intra- and inter-colony variability in thermal tolerance is likely allows tropical ant species to better cope with climate change. Our results underscore why ecological research must examine multiple levels of biological organisation.

It is now a cliché to highlight that whilst artificial intelligence (AI) provides many opportunities, it also presents myriad risks to established norms. Amongst the norms considered in the literature, the Rule of Law unsurprisingly features. But the analyses of the Rule of Law are narrow. AI has the capacity to augment as well as to undermine fidelity to the ideal of the Rule of Law. Rather than viewing AI only as a threat to important norms, this article’s core argument is that AI should also be presented as an opportunity to meet their demands. It uses the Rule of Law in tax administration to support this argument.

This semi-systematic literature review examines signed language corpus research in the Nordic countries, with a quantitative and qualitative assessment of corpus research. The article first describes some critical components and functionalities of signed language corpora. It then outlines the evolution of Nordic corpus research, highlighting Sweden’s pioneering role and subsequent developments in Finland and Norway. The findings suggest a progression from method-focused publications to those exploring linguistic phenomena within and across (signed) languages. Although the number of research publications is modest, there is a discernible shift towards comparative studies and applications in signed language teaching and learning.

One of the less popular and less investigated topics of law is the use of biocontrol agents (BCAs). Despite the general growing attention to the use of BCAs in primary production, a comprehensive regulatory framework is still lacking. When shifting to possible uses of BCAs in the following phases of the food chain, legislation is even more incomplete (and inadequate) despite the challenging opportunities they offer both for pest control and for pathogen control. The paper will provide an overview of the uses of BCAs taking into consideration all the food chain stages, the relevant partial EU regulatory scheme and its critical issues.

This article examines what the state of the law regarding the tortious protection of the privacy of corporations tells us about the concept of a legal person. Given that non-human persons are capable of having an interest in at least their informational privacy, logic would seem to dictate that they should be recognised such a right protecting their personality. In reality, the law is most hesitant to concede the right to privacy to non-natural persons (the same being true of reputation). This suggests that, for the dominant strand of the law at least, despite the rhetoric, legal persons do not really have rights of personality; in other words, that they are not really persons.

The relationship of the Late Cretaceous amphibolite-facies Akrotiri and Vari subunits on the Greek islands of Tinos and Syros to similar occurrences in the Aegean is not fully understood, but a correlation with the Asterousia Crystalline Complex on Crete and corresponding rocks in the Upper Cycladic Unit on other islands of the archipelago is a plausible interpretation. There is currently no clear evidence that the Akrotiri subunit represents a fragment of the metamorphic sole of the nearby Tsiknias ophiolite, as there are differences in field appearance, geochemistry, metamorphic grade and retrograde overprint. Felsic rocks from amphibolite-gneiss sequences of the Akrotiri and Vari subunits are interpreted as reworked igneous rocks with minor admixture of terrigenous material. The Triassic U–Pb zircon age (c. 240 Ma) of such a gneiss from Syros indicates the magmatic crystallization age of the original source rocks. A similar interpretation is suggested for the studied Akrotiri gneiss, but is less clear due to the not fully clarified significance of the presumed Pb loss thought to be responsible for the considerable U–Pb age range of the dated zircons (c. 256–114 Ma). The Vari gneiss sensu strictu is closely associated with metadioritic rocks containing a Triassic zircon population (c. 238 Ma). The protolith is probably plutonic, but a mixture of volcanic and plutonic detritus cannot be excluded. Riebeckitic amphiboles occur in all rock types of the Akrotiri subunit, indicating late overprinting at elevated pressures, which is not known from similar occurrences in the southern Aegean.

The authors' aim is to build “more biologically plausible learning algorithms” that work in naturalistic environments. Given that, first, human learning and memory are inextricable, and, second, that much human learning is unconscious, can the authors' first research question of how people improve their learning abilities over time be answered without addressing these two issues? I argue that it cannot.

This article argues that covert action is subordinate to security narratives, with covert action demanded by, empowered through, and used to decisively impact the narratives of security threat that concern a state’s key power-granting audiences. A narrative approach to analysing covert action is developed based on narratology and securitisation. This approach reconciles the paradoxical historical record of implausible deniability with International Relations theory, and challenges other risk-led approaches to understanding covert action. The narrative approach is supported by a class-severity model which updates existing ladder models of covert action escalation, enabling scholars to both detect occurrences of covert action and suggest attribution to an actor – a vital initial step for the study of non-Western covert action in particular. The narrative approach also enables the effectiveness of covert action to be measured in terms of its impact on security narratives, overcoming the limitations of existing approaches. The article employs these tools to analyse Russia’s 2014 annexation of Crimea, delivering new insight and identifying areas for further study for a key non-Western user of covert action.

Osteoarthritis (OA), a disease with a multifactorial aetiology and an enigmatic root cause, affects the quality of life of many elderly patients. Even though there are certain medications utilised to reduce the symptomatic effects, a reliable treatment method to reverse the disease is yet to be discovered. Zinc is a cofactor of over 3000 proteins and is the only metal found in all six classes of enzymes. We explored zinc’s effect on the immune system and the bones as OA affects both. We also discussed zinc-dependent enzymes, highlighting their significant role in the disease’s pathogenesis. It is important to note that both excessive and deficient zinc levels can negatively affect bone health and immune function, thereby exacerbating OA. The purpose of this review is to offer a better understanding of zinc’s impact on OA pathogenesis and to provide clarity regarding its beneficial and detrimental outcomes. We searched thoroughly systematic reviews, meta-analysis, review articles, research articles and randomised controlled trials to ensure a comprehensive review. In brief, using zinc supplementation in the treatment of OA may act as a doubled-edged sword, offering potential benefits but also posing risks.
