In the last two decades, the adoption of exoskeletal devices for the reduction of the biomechanical overload of workers has hugely increased. They allow relief of the biomechanical load of the operator and ensure the operator’s contact with the object without binding its interaction. In this work, the biomechanical and physiological effects on the user wearing upper limb passive exoskeletons have been evaluated to highlight the benefits and possible drawbacks introduced by their use in typical manufacturing tasks. MATE and PAEXO Shoulder passive exoskeletons have been assessed during the execution of different working gestures among static, dynamic, and quasi-static tasks on 16 healthy volunteers. The obtained results confirm that the adoption of such systems significantly impacts the users by reducing the muscular load, increasing endurance, and reducing the perceived effort. Moreover, this analysis pointed out the specific benefits introduced by one exoskeleton with respect to the other according to the specific task. The MATE has the potential to reduce muscle load during the execution of static tasks. Conversely, the PAEXO Shoulder positively impacts the users’ biomechanical performances in dynamic tasks.

Presented here is a novel formulation of the mean-field dynamo as a modulational instability of magnetohydrodynamic (MHD) turbulence. This formulation, termed mean-field wave kinetics (MFWK), is based on the Weyl symbol calculus and allows describing the interaction between the mean fields (magnetic field and fluid velocity) and turbulence without requiring scale separation that is commonly assumed in the literature. The turbulence is described by the Wigner–Moyal equation for the spectrum of the two-point correlation matrix (Wigner matrix) of magnetic-field and velocity fluctuations and depicts the turbulence as an effective plasma of quantum-like particles that interact via the mean fields. Eddy–eddy interactions, which serve as ‘collisions’ in this effective plasma, are modelled within the standard minimal tau approximation to aid comparison with existing theories. Using MFWK, the non-local electromotive force is calculated for generic turbulence from first principles, modulo the limitations of MFWK. This result is then used to study, both analytically and numerically, the modulational modes of MHD turbulence, which appear as linear instabilities of the said effective quantum-like plasma of fluctuations. The standard $\alpha ^2$-dynamo and other known results are reproduced as special cases. A new dynamo effect is predicted that is driven by correlations between the turbulent flow velocity and the turbulent current.

Grammaticalization is the process whereby lexical items change into grammatical items. This phenomenon is widely attested, while the change from grammatical to lexical is far less common. We ran two experiments to test whether this unidirectional tendency originates with a preference for extending lexical meanings to grammatical ones rather than vice versa. We focus on body parts and spatial relations. In Experiment 1, participants were told the meaning of an artificial word then rated how likely it is that that word can also be used to refer to a second meaning – one meaning was a body part and one a preposition. We expected higher ratings when extending from body parts to prepositions than vice versa but found no difference. In Experiment 2, participants performed semantic extension in communication. We varied whether they extended words for body parts to prepositions or vice versa. Again, we found no asymmetry. Finally, we used a model of Experiment 2 to show that asymmetrical extension follows straightforwardly if there is an asymmetry in the number of words available relative to the number of meanings to express, indicating that having a larger number of lexical items than grammatical concepts could be an alternative source of unidirectionality.

We study certain categories associated to symmetric quivers with potential, called quasi-Bogomol’nyi–Prasad–Sommerfield (BPS) categories. We construct semiorthogonal decompositions of the categories of matrix factorizations for moduli stacks of representations of (framed or unframed) symmetric quivers with potential, where the summands are categorical Hall products of quasi-BPS categories. These results generalize our previous results about the three-loop quiver. We prove several properties of quasi-BPS categories: wall-crossing equivalence, strong generation, and a categorical support lemma in the case of tripled quivers with potential. We also introduce reduced quasi-BPS categories for preprojective algebras, which have trivial relative Serre functor and are indecomposable when the weight is coprime with the total dimension. In this case, we regard the reduced quasi-BPS categories as noncommutative local hyperkähler varieties and as (twisted) categorical versions of crepant resolutions of singularities of good moduli spaces of representations of preprojective algebras. The studied categories include the local models of quasi-BPS categories of K3 surfaces. In a follow-up paper, we establish analogous properties for quasi-BPS categories of K3 surfaces.

We investigate the primitive recursive content of linear orders. We prove that the punctual degrees of rigid linear orders, the order of the integers $\mathbb {Z}$, and the order of the rationals $\mathbb {Q}$ embed the diamond (preserving supremum and infimum). In the cases of rigid orders and the order $\mathbb {Z}$, we further extend the result to embed the atomless Boolean algebra; we leave the case of $\mathbb {Q}$ as an open problem. We also show that our results for the rigid orders, in fact, work for orders having a computable infinite invariant rigid sub-order.

Understanding the developmental and occupational histories of Ancestral Maya settlements is crucial for interpreting their roles in broader social, political, and economic dynamics. This article presents 62 new accelerator mass spectrometry (AMS) 14C dates from residential groups in the outlying settlement zone at Alabama, a major inland Ancestral Maya center in East-Central Belize. Alabama is a rare example of a “boomtown” in the Maya lowlands, experiencing rapid development primarily during the 8th and 9th century CE, corresponding to the Late to Terminal Classic periods. Using Bayesian stratigraphic sequence models, we construct detailed developmental and occupational histories for the townsite, clarifying the timing of its development, occupation, and abandonment. Our analysis reveals complex residential histories, confirming a rapid tempo of Late and Terminal Classic settlement growth and indicating continuities in occupation into the 10th century CE and beyond. Furthermore, we identify two separate periods of occupation during the Early Classic (cal AD 345–545) and the Late Postclassic (cal AD 1325–1475), demonstrating that parts of the settlement were inhabited at different intervals over many centuries. These results offer the first detailed deep-history perspective for the East-Central Belize region, establishing a framework that addresses challenges in chronology-building posed by poor pottery preservation and the complexities of earthen-core architecture at the site and enabling future chronological modeling in this lesser-known frontier of the eastern Maya lowlands.

India’s 1947 independence and the violent birth of Pakistan had a major and still unexplored impact in West Africa. Despite existing studies assessing Gandhi’s intellectual impact on African leaders, little scholarship has examined African perceptions of events in India and Pakistan. Examining the case of Nigeria, this article moves from a brief history of Nigerians’ interest in South Asian politics during the 1940s to identify two key elements of Nigerians’ responses. First, it demonstrates how Nigerian politicians, journalists and religious leaders advanced ambiguous and nuanced critiques of Indian politics on the eve of independence. The possibility of a ‘Nigerian Gandhi’ particularly preoccupied observers, who made comparisons between the Indian leader and local nationalists. Second, the article argues that the formation of Pakistan had a largely unrecognized impact on Nigerian political culture in the late 1940s. In a crisis about separatism and ‘Pakistanism’, Nigerian commentators engaged substantively with the ideals represented by this new state and the violence of Partition itself. The article argues that reactions to Asia were differentiated by region, and Northern Nigerian intellectuals developed separate critiques of South Asian affairs. Rather than understanding South Asia’s impact on West Africa simply in terms of ‘influence’, this article reveals how Africans drew on South Asia to map their own futures.

Follicle-stimulating hormone (FSH) must be applied at 12-h intervals over 4–5 days in the traditional cattle superovulation protocol, which still needs to be improved. This research paper evaluated the superovulation results obtained by a traditional protocol or by a single administration of FSH dissolved in MontanideTM ISA-206 VG (MonISA-206). Control cows were superovulated with 10 mL of FSH (500 µg pFSH + 100 µg pLH) from day 7 to day 10 (for 4 days, twice daily i.m. injections, decreasing doses). Cows in the EG10 and EG7.5 groups were injected i.m. with 20 mL (100%, 10 mL + 10 mL) or 15 mL (75%, 7.5 mL + 7.5 mL) of the FSH and MonISA-206 mixture at once on day 7. All cows were inseminated 12 and 24 h after oestrus onset. The cows presented no pathology at the injection sites. Plasma FSH levels differed between the groups, but the interaction between hour and group × time was not different. Superstimulation and embryo quality results were similar between the groups. A single injection of FSH (both 100% and 75% doses) dissolved in MonISA-206 led to adequate plasma FSH levels and similar superovulation results to traditional FSH treatment, and caused no pathology at the injection sites.

This article traces the origins of “big” tobacco, that is, international, multinational companies, in Cyprus during the British colonial period. It explores how the tobacco and cigarette industries developed from the 1920s until the end of colonial rule in 1960, and how “big” tobacco companies united and came to control these industries. The article shows that from the 1920s, and especially from the 1940s, the prevalence of smoking in Cyprus was exceedingly high. This corresponded to the large-scale importing of foreign-made cigarettes and the manufacture of cigarettes by local companies, before the first international company began to manufacture cigarettes in the island in 1951. The article explores how the British colonial governments and civil society did little to make the Cypriot people aware of the dangers of cigarette smoking, despite medical research linking cigarette smoking to the increase in lung cancer in 1950 and the debates and warnings in the UK. Ultimately, the origins and evolution of “big tobacco” companies in Cyprus had a profound impact on the local industry and the prevalence of cigarette smoking in Cyprus.

Front-line workers mediate law on the books and law in action, translating higher-level laws into local policy. One important mediating institution is the police. Whereas most research analyzes how the law empowers police to label certain denizens “criminals” – both within and outside criminal legal contexts – this article demonstrates how policing also affects who is recognized as an innocent crime victim. Synthesizing existing scholarship, I theorize three paths through which police can affect legal recognition of crime victims: criminalization, minimization, and legal estrangement. I then test the extent to which these processes affect victims’ access to public benefits provided under victim compensation law. Drawing on never-before-analyzed administrative data from 18 U.S. states (N = 768,382), I find police account for more than half of all victim benefits denials. These denials are racialized and gendered: Police are significantly more likely to criminalize and be estranged from Black male victims and significantly more likely to minimize the injuries of Black female victims. Additional qualitative data suggest police systematically perceive Black men as not truly innocent and Black survivors of gender-based violence as not truly victims. These findings advance our understanding of the expansive role of police in society as well as the porous boundary between social provision and social control.

This research article addresses the hypothesis that vehicles used for cattle transport are contaminated with Escherichia coli, a potential foodborne pathogen, despite current regulations on sanitation practices. Dairy cattle and calves are regularly transported to auction markets, calf rearers and slaughterhouses. UK Government guidelines require livestock transport vehicles to be cleaned and disinfected within 24 hours of use or before re-use within that period. It is feasible, however, that if cleaning fails to eradicate bacteria, then transport vehicles can act as a fomite in the spread of antimicrobial resistance (AMR) pathogens. In this study, 13 trailer-loads (TLs) of calves were transported for 40–60 minutes. Trailers were then cleaned and disinfected within 20 minutes of unloading. Five sites within the trailer were swabbed after pressure washing and again 30 minutes after application of disinfectant. A bacterial count for E. coli was performed through growth on selective agar, and species identification was confirmed by MALDI-TOF. A subset of 30 isolates was selected for antibiotic susceptibility screening to a panel of veterinary and human antibiotics. E. coli were recovered from all TLs and sites; however, not all sites were contaminated in each TL. E. coli count was significantly reduced, but not eliminated, following application of disinfectant. Furthermore, high prevalence of resistance to sulphonamides, first-generation cephalosporins, and tetracyclines was observed. Forty percent of screened isolates were also classified as multidrug-resistant (MDR) (i.e. resistant to at least one antibiotic from three or more antibiotic classes). Application of disinfectant did not increase the risk of recovering an MDR isolate. This study demonstrates that livestock trailers can harbour potential zoonotic pathogens with AMR properties. Disinfection in accordance with current guidelines is an important step in reducing, but not eradicating, bacterial populations in these vehicles. Improved cleaning and/or disinfection policies are required to mitigate the potential for AMR transmission.

Non-autonomous self-similar sets are a family of compact sets which are, in some sense, highly homogeneous in space but highly inhomogeneous in scale. The main purpose of this paper is to clarify various regularity properties and separation conditions relevant for the fine local scaling properties of these sets. A simple application of our results is a precise formula for the Assouad dimension of non-autonomous self-similar sets in $\mathbb{R}^d$ satisfying a certain “bounded neighbourhood” condition, which generalises earlier work of Li–Li–Miao–Xi and Olson–Robinson–Sharples. We also see that the bounded neighbourhood assumption is, in few different senses, as general as possible.

This study compared a culture-based protocol in which only cows identified as having intramammary infections due to major pathogens (major IMI) were treated with dry cow antibiotics (DCAT) compared with the current New Zealand somatic cell count (SCC) and mastitis-based algorithm. Healthy multiparous pregnant lactating cattle (n = 1541) were enrolled from three spring-calving New Zealand farms. A composite four-quarter milk sample was collected aseptically prior to the last milking before dry-off. Samples underwent standard culture and a culture using a novel, custom-made agar plate. Enrolled animals were classified as having a major IMI on 1) standard culture; 2) novel culture and 3) having SCC > 150,000 cells/ml at the last herd test and/or clinical mastitis (CM) in the current lactation. The sensitivity and specificity of novel culture and SCC/mastitis history for identifying cows with major IMI (compared with standard culture) were calculated. Cows were then blocked by standard culture results (major, minor or no growth) and randomly allocated to treatment based on either novel culture results (cult-SDCT) or SCC/mastitis history (alg-SDCT). Cows allocated to cult-SDCT whose novel culture result was major pathogen positive or contaminated received DCAT, while for alg-SDCT cows, all cows with either SCC > 150,000 cells/ml at the last herd test or CM in the current lactation received DCAT. The sensitivity (0.80 vs 0.67) and specificity (0.91 vs 0.81) for major IMI prediction were greater for cult-SDCT than alg-SDCT. After accounting for farm, age and dry-off SCC, alg-SDCT cows had marginal mean SCC at first herd test post-calving of 129,000 (95% CI 116–143,000) cells/ml, whereas the equivalent for cult-SDCT cows was 113,000 (95% CI 101–126,000) cells/ml. Compared to alg-SDCT, using cult-SDCT correctly identified a higher proportion of major IMI identified by standard culture and did not result in an increase in post-calving SCC.

The 1970s saw intense discussions among feminists about the patriarchal family. While radical feminists called for complete withdrawal from marriage and motherhood, others attempted to reconfigure the roles of parents and children in the light of feminism. A particularly vibrant discussion unfolded in the feminist magazine Effe, published in Rome between 1973 and 1982, evolving from a largely negative to a more nuanced view of motherhood by the late 1970s. The notion of love was central. Effe writers asked how love could be separated from care and if it was really so natural. They stressed how maternal love needed to be balanced with children’s need for freedom and autonomy and reflected on their experiences as daughters as well as mothers. While excessive love could be harmful, there was radical potential in the notion of the loved and wanted child. Many proposed collective solutions to child-rearing, while others stressed the sensual pleasures of motherhood. Using a history of the emotions lens, this article teases out the complexities and contradictions of Italian feminist thinking about motherhood. Although the space for more positive evaluations expanded over time, Effe was ultimately more successful in reclaiming pregnancy as a feminist experience than motherhood itself.
