Authors: Feng Zhiyuan , Si Minmin , Fan Hao , Zhang Yin , Yuan Rui , Hao Zhaonan 
Published: December 2023

Abstract
Objectives
The study aims to conduct a bibliometric analysis on maxillary skeletal expansion to elucidate the evolution and current status and predict future research hotspots and trends.

Material and methods
A search was conducted in the Web of Science Core Collection at the University of Hong Kong’s electronic library using the query “(TS = maxillary expansion) AND (TS = skeletal expansion).” The resulting literature data were imported into CiteSpace 6.2.R4 and VOS viewer software to analyze authorship, countries, institutions, keywords, etc.

Results
A total of 923 articles were analyzed. The research in this field has shown a steady growth, with a significant increase since 2019. The USA and Italy have played prominent roles in contributing to the publication volume and strengthening collaborative exchanges. Clustering labels provide directions for in-depth analysis of the literature.

Conclusions
(1) MARPE (miniscrew-assisted rapid palatal expansion) and SARME (surgically assisted rapid maxillary expansion) have gained widespread attention and become research hotspots due to their applicability in adults whose growth and development have ceased, while still producing favorable skeletal effects.
(2) In addition to widening the maxillary arch, maxillary expansion techniques have shown significant effects on increasing nasal cavity width and volume. However, there is still controversy regarding whether they can effectively improve the deviated nasal septum.
(3) Maxillary skeletal expansion techniques have been shown to increase upper airway volume and improve breathing, making them potentially valuable in the treatment of obstructive sleep apnea (OSA).

Clinical relevance
This study can provide cutting-edge clinical recommendations for healthcare professionals to better formulate clinical strategies.
Who gets the treat: Interspecific interactions between red squirrels and corvids in an urban park
Authors: Beliniak Agata , Krauze-Gryz Dagny 
Published: December 2023

AbstractSquirrels and some corvids have successfully adapted to urban conditions. Their populations are often more abundant in city parks than in rural areas. These species may compete, especially in terms of food resources. We studied interactions between corvids (hooded crows and rooks) and red squirrels inhabiting urban park, mostly in relation to supplementary food utilisation in Poland. The study included the following: (a) feeding trials, when squirrels were offered hazelnuts and all stealing attempts by other animals were noted; (b) direct observations of groups of animals (at least one squirrel and one corvid species) with all behaviours being recorded. During the feeding trial, and with constant corvid presence, corvids tried to steal almost every third nut cached by squirrels. Regardless of the season, the share of nuts that corvids tried to steal was similar. When the feeding trial proceeded, more squirrels joined in order to obtain food. On the contrary, the presence of corvids seemed to refrain other corvids from joining the trial. The presence of a bird/squirrel audience did not result in more deceptive caches. During direct observations, squirrels interacted mostly with corvids, and less often with people or other squirrels. The most frequent interaction of squirrels with other animals was flight and chasing away; for corvids, it was chasing and following or attempting to steal food. Overall, we showed that corvids can be food competitors and kleptoparasites for red squirrels. Red squirrels, with whom people often have affinity relationships, benefited from direct supplementary feeding. Corvids, in turn, learnt to follow red squirrels to steal human-delivered nuts.
Possible remediation of impact-loading debris avalanches via fine long rooted grass: an experimental and material point method (MPM) analysis

Published: December 2023

AbstractDebris avalanches often originate along steep unsaturated slopes and have catastrophic consequences. However, their forecast and mitigation still pose relevant scientific challenges. This is also due to the variety of mechanisms observed near high sub-vertical bedrock outcrops, such as the impact loading of soil failed upslope the outcrop, the build-up of pore water pressures in the inception zone, and the bed entrainment along the landslide propagation path. At the University of Salerno, an experimental and numerical investigation campaign started some years ago to explore the feasibility of using long-root grass to mitigate or even inhibit the inception of debris avalanches. Previous laboratory results were achieved through two twin 2-m-long columns (one bare, one vegetated), where the change in soil retention curve and soil mechanical response was assessed. As follow-up, an experimental field setup was installed in 2020 first, and in an improved configuration in 2021. Here, three different species of long-root grass were grown. In situ soil suction and water content measurements were periodically collected in the vegetated and in the original soils. In both cases, soil specimens were also collected, and laboratory geotechnical tests were performed to individuate the changes in both the water retention and strength response. Increased values of soil suction and shear strength were outlined, despite some differences, for all the grown species compared to the original soil. Using these novel experimental data, advanced large-deformation stress–strain hydro-mechanically coupled analyses were recently performed through a material point method (MPM) approach. The original slope conditions were compared to various slope configurations engineered via long-root grass. The benefits and the open issues related to this novel green technology for landslide mitigation are discussed. Some insights are outlined for the possible reduction of the soil volumes mobilized inside the inception zone of debris avalanches.

Published: December 2023

AbstractThe millimeter wave spectrum fulfills the demand for higher data rates with low latency. Moreover, futuristic wearable gadgets demand flexible antennas operating at these frequencies, such that they can easily be accommodated. Therefore, the article focuses on designing a compact and highly flexible antenna with the aid of characteristic mode analysis (CMA). A thin polyimide substrate of 0.1 mm thickness is used to maintain flexibility. The overall antenna profile is $$0.61{\lambda }_{0} \times 0.61{\lambda }_{0}$$

. The design evolves through four stages, where, in each stage, the solution to the surface current through eigenvalue leads to significant modes. The final stage design generated Mode 2 fundamental mode at 30.5 GHz along with contributing Modes 3 and 5 with a bandwidth range of 28-31.5 GHz. Further, the design is simulated using electromagnetic simulation software, and the prototype is fabricated. The simulated and measured reflection coefficient |S11| > 10 dB in 28.72-32 GHz and 28.9-31.75 GHz. The CMA analyzed, simulated, and measured gain is 4.82 and 5.6 dBi, respectively. The proposed antenna has a stable response for conformal orientations along the x and y-axis. The antenna has resulted in bidirectional radiation in the XZ plane with simulated and measured half-power-beam-width (HPBW) of 58° and 54°. In the YZ plane, it resulted in omnidirectional radiation. The simulated and measured results are in good agreement. The article also performs the link budget analysis. It suggested that the antenna can communicate 100 Mbps of data to a distance of 100 m and 1 Gbps of data up to 70 m. Thus, the proposed antenna structure is suitable for wearable, IoT, and other 5G wireless applications.

Local to global principles for homomorphisms of abelian schemes
Authors: Gajda Wojciech , Petersen Sebastian 
Published: December 2023

AbstractLet A and B be abelian varieties defined over the function field k(S) of a smooth algebraic variety S/k. We establish criteria, in terms of restriction maps to subvarieties of S, for existence of various important classes of k(S)-homomorphisms from A to B, e.g., for existence of k(S)-isogenies. Our main tools consist of Hilbertianity methods, Tate conjecture as proven by Tate, Zarhin and Faltings, and of the minuscule weights conjecture of Zarhin in the case when the base field is finite.
Alter-nation? Factions, Coalitions and Environmental Governance in the Context of Contested Post-apartheid Local State Democratisation
Authors: Thakur Shaheen Sewparsadh , Nel Adrian 
Published: December 2023

AbstractMany African states have become electoral democracies, but others are still run by electoral authoritarian regimes, and/or exhibit procedural but not more substantive emancipatory extensions of rights and functions. In such contexts, alternation of power, or electoral turnover, has been recognised as a key signifier of successful democratisation. South Africa’s post-apartheid democratic transition was widely lauded as a textbook case, yet declining support for the political incumbent, factionalism, the phenomena of “state-capture” and the decline of state-owned entities has raised questions about the promises and challenges of post-African National Congress (ANC) hegemony. Limited research in South Africa (SA) focuses on the influence of political contest — including alternation, coalition formation and factionalism on municipal Environmental Governance (EG). Accordingly, we provide an analysis of political contest in both single and coalition councils between 2016 and 2021 in the of the Endumeni Local (ELM) and uMzinyathi District (UDM) municipalities in KwaZulu-Natal (KZN), SA, focusing on environmental governance implications. The study was theoretically framed by a broad Political Ecology Approach (PEA). A mixed-method research approach consisting of qualitative and quantitative data collection techniques was utilised. The findings revealed contested politics and instability in both single and coalition councils, regardless of who governs. and this predominantly constrained, but in few instances enabled EG. This complicates narratives of alternation and coalition politics and points to the broader and ongoing need for council policy reform, local council stability, municipal competence and accountability.
The stone artifacts of the National Archaeological Museum of Adria (Rovigo, Italy): a noteworthy example of heterogeneity

Published: December 2023

AbstractThis paper reports on the results of the analyses of 56 stone samples from Roman and pre-Roman artifacts from the ancient town ofAtria, currently preserved at the National Archaeological Museum of Adria. The city is located in the eastern Veneto lowlands, close to the Po River delta, and far from the main rock outcrops of the region. The objective of this research is to determine the provenance of the stones used in ancientAtriaand their trade networks. The analytical techniques adopted include polarized-light optical microscopy (PLM), X-ray fluorescence (XRF), and quantitative phase analysis by X-ray powder diffraction (QPA-XRPD). The results reveal a widespread use of imported stones from the central-western territories of Veneto, primarily comprising trachyte from the Euganean Hills and the soft limestone Vicenza Stone from the Berici Hills/eastern Lessini Mounts. Rosso Ammonitico, Maiolica (Biancone) and Scaglia Rossa limestones are also documented. From neighbouring regions, the imported stone types include Aurisina limestone from the Trieste Karst and Istrian Stone. Sandstone was uniquely recognized in G. Popillius’s milestone. Moreover, advanced geochemical and mineralogical analyses performed on the Euganean trachytes allow tracking accurately the quarry sites, revealing an extensive exploitation of the main historical quarries of M. Oliveto, Monselice and M. Merlo, although some provenances from outcrops less systematically exploited were also detected. Notably, the use of rhyolite for manufacturing a pre-Roman gravestone provides new insights regarding the exploitation of Euganean stone resources before the Roman era.
Disciplining Health Regulations through the World Trade Organization’s Agreement on the Application of Sanitary and Phytosanitary Measures: Science and the Rule of Law
Authors: Prévost Denise 
Published: December 2023

AbstractThe World Trade Organization’s (WTO) Agreement on Sanitary and Phytosanitary Measures (SPS Agreement) disciplines WTO Members’ health regulations to prevent their misuse for protectionist purposes. In doing so, its obligations reflect several elements of the rule of law, including legal certainty, non-arbitrariness and non-discrimination, as well as a recognition of the rights of individuals. Through its obligations of non-discrimination, transparency and scientific justification and the scope it leaves for Members to prioritise the protection of health over trade liberalisation, the SPS Agreement can be regarded as entailing a rule-of-law approach. However, cognisant of the limits to the rule of law when transposed to the international level, it is important to avoid an overly “judicialised” approach to the disciplines of the SPS Agreement, and in particular its reliance on scientific justification to prevent arbitrariness in sanitary and phytosanitary regulation. Otherwise, there is a risk of intruding too far into the regulatory autonomy of States, weakening the “compliance pull” of the agreement and thus inadvertently undermining the rule of law in this area. An approach that instead recognises the inherent subjectivity and uncertainty in science and respects Members’ divergent priorities in health regulation would go further in engendering support for the rules-based system of international trade.
Aesthetic emotional reactions and their verbal expression in a corpus of Japanese travellers’ online reviews
Authors: Díaz-Vera Javier E. 
Published: December 2023

Abstract
Using Conceptual Metaphor Theory, I propose a study of aesthetic emotional expressions in Japanese. With this aim, I have created a medium-sized corpus (c100,000 running words) of travellers’ reviews in Japanese published on TripAdvisor between 2012 and 2022. The corpus consists of 1,100 reviews, grouped into three subsections, corresponding to three of the most visited landmarks in Japan (namely, Mount Fuji, Fushimi Inari-Taisha Shrine, and the Hiroshima Atomic Bomb Dome). The reviews chosen for this research include at least one reference, either literal or figurative, to the users’ aesthetic evaluation of their visit. My list of aesthetic emotions consists of four large categories: emotions of pleasure (e.g., attraction, fluency), emotions of contemplation (e.g., interest, intrigue), emotions of amazement (e.g., awe, wonder), and emotions of respect (e.g., admiration, adoration). For each aesthetic emotion, I have identified a series of source domains, which I analyse in detail in my discussion. As my data shows, many of our aesthetic expressions are rooted in the psychological and behavioural changes triggered by these emotions and, therefore, should be considered embodied. More importantly, through the analysis of the conceptual mappings involved in these linguistic expressions, it can be affirmed that aesthetic reactions are sensitive to cultural influences and, thus, they are not necessarily universal.
Navigating “Race” at Tahiti: Polynesian and European Encounters
Authors: Elliston Deborah 
Published: December 2023

AbstractIn this article I analyze stories about the negotiation of European racialization ideologies in the Society Islands (Tahiti and its Islands) in the late eighteenth century. My focus is the disjunctures between European understandings of their encounters at Tahiti, and what Pacific scholars have come to understand of Polynesian understandings of themselves and various foreigners in that early period. In doing so, I draw out the ways sexuality and gender mediated, enabled, and were also constituted through such racialization processes in their cultural and historical specificity. A key point of departure for this analysis is that the embodiment of race is a negotiated social process. The comparative historical case study I offer up here follows current scholarly moves in seeking out the insights to be gained by tracking racialization as a contingent process, as open rather than closed, as variegated rather than singular, and as imperfectly and only tenuously wrought through ideologies that may be profoundly unanticipated from the vantage point of modernist logics of essentialism and foundationalism. The resulting analysis aims to create space for critically revisiting the ways in which racial normativities and racialized embodiment operate, and how they work, and fail to work, to promote naturalized racist hierarchies of privilege and subordination.
Morpho-molecular characterisation of two new and two previously reported species of Acanthogyrus (Acanthogyrus: Quadrigyridae) from freshwater fishes in India
Authors: Rana K. , Kaur H. 
Published: December 2023

Abstract
Of the total 47 species in the subgenus Acanthosentis, 43 have been reported from the freshwater fishes of Asia. Amin et al. (2017) provided a key to the 23 species of the genus Acanthogyrus reported from the Indian subcontinent. The present study reports two new species: Acanthogyrus bispinosa n. sp. and A. garciai n. sp. from Cirrhinus mrigala Hamilton and Labeo calbasu Hamilton, respectively, and two previously described species: A. golvani Gupta and Jain, 1980 and A. hereterospinus Khan and Bilqees, 1990 from L. rohita Hamilton and L. catla Hamilton, respectively. A. bispinosa n. sp. comprises 3 circles of 6 proboscis hooks each. Trunk spines in A. bispinosa n. sp are divided into two groups: anterior and posterior separated by unarmed region, which has not been previously reported in the subgenus. Anterior spines are present in 7–8 and 7–10 circles in females and males, respectively, whereas posterior spines are in 23–28 and 31–38 circles in males and females, respectively. A. garciai n. sp. comprises 3 circles of 6–8 hooks each and a single set of trunk spines is present in A. garciai n. sp., comprising 35–42 and 25–45 circles in males and females, respectively. All four species were also characterised based on the 18S, 28S, and ITS1-5.8S-ITS2 rRNA molecular markers. The Bayesian inference tree generated based on these markers showed distinct identities of all the species, with a significant molecular divergence, ranging from 3.2 to 53.6%.
No time to relax: Age-dependent infectivity of cercariae in marine coastal ecosystems
Authors: Nikolaev Kirill E. , Fedorov Daniil D. , Vinogradova Anna A. , Levakin Ivan A. , Galaktionov Kirill V. 
Published: December 2023

Abstract
Age dynamics of the ability of cercariae of two digenean species, Himasthla elongata (Himasthlidae) and Renicola parvicaudatus (Renicolidae), to infect the second intermediate host (SIH), mussels (Mytilus edulis), was investigated experimentally. This is the first study of this kind made on cercariae transmitted in the intertidal of the northern seas. The larvae of all tested ages (from 0.5 to 6 hr) were equally successful in infecting mussels. This finding disagrees with the literature data on cercariae of several freshwater digeneans, which are practically incapable of infecting the SIH during the first 1–3 hr of life. The presence of a time delay before the attainment of the maximum infectivity (TDMI) may be associated with the need for physiological maturation of cercariae in the very beginning of their life in the environment, the need for their broad dispersion, and the prevention of superinfection of the downstream host. The absence of TDMI in the cercariae examined in our study could be associated with the instability of environmental factors in the marine intertidal (wave impact, tidal currents). These factors promote a broad dispersion of cercariae in the intertidal biotope and prevent superinfection of potential SIHs. Biological and behavioural features may also play a role. We hypothesize that the presence or absence of TDMI does not depend on the taxonomic affiliation of the cercariae but is determined by the transmission conditions.
Sounds in context: Archaeoacoustical studies of instruments from Comalcalco and Jonuta, pre-Hispanic Maya sites
Authors: Zalaquett Francisca , Gallegos Miriam Judith , Armijo Ricardo , Espino Dulce 
Published: December 2023

AbstractSounds produced by humans and their environment are perceived and codified based on people's experiences as members of social groups, resulting in some sounds being used as means of communication. In this article, we present an archaeoacoustic study of diverse types of instruments excavated or collected from Comalcalco and Jonuta, two important pre-Hispanic Maya sites located in the modern state of Tabasco (Mexico). We propose a methodology to analyze organological and acoustic characteristics for each type of instrument, considering their relevant archaeological information, so as to provide some interpretations of how sounds could have been materialized, shared, and used in specific moments of Maya ritual and daily life.
