Published: February 2025

Abstract
Renewable 2,5-furandicarboxylic acid-based polyesters are one of the most promising materials for achieving plastic replacement in the age of energy and environmental crisis. However, their properties still cannot compete with those of petrochemical-based plastics, owing to insufficient molecular and/or microstructure designs. Herein, we utilize the Ti3C2Tx-based MXene nanosheets for decorating carbon nanotube (CNT) and obtaining the structurally stable and highly dispersed dendritic hetero-structured MXene@CNT, that can act as multi-roles, i.e., polycondensation catalyst, crystal nucleator, and interface enhancer of polyester. The bio-based MXene@CNT/polybutylene furandicarboxylate (PBF) (denoted as MCP) nanocomposites are synthesized by the strategy of “in situ catalytic polymerization and hot-pressing”. Benefiting from the multi-scale interactions (i.e., covalent bonds, hydrogen bonds, and physical interlocks) in hybrid structure, the MCP presents exceptional mechanical strength (≈101 MPa), stiffness (≈3.1 GPa), toughness (≈130 MJ m−3), and barrier properties (e.g., O2 0.0187 barrer, CO2 0.0264 barrer, and H2O 1.57 × 10−14 g cm cm−2 s Pa) that are higher than most reported bio-based materials and engineering plastics. Moreover, it also displays satisfactory multifunctionality with high reprocessability (90% strength retention after 5 recycling), UV resistance (blocking 85% UVA rays), and solvent-resistant properties. As a state-of-art high-performance and multifunctional material, the novel bio-based MCP nanocomposite offers a more sustainable alternative to petrochemical-based plastics in packaging and engineering material fields. More importantly, our catalysis-interfacial strengthening integration strategy opens a door for designing and constructing high-performance bio-based polyester materials in future.
Increased Trophoblast Cell Ferroptosis via HMGB1/ACSL4 Pathway Is Associated with Spontaneous Abortion
Authors: Dong Yishan , Li Yong , Tang Wenjie , Chen Qin , Kong Chengcai 
Published: February 2025

Abstract

Introduction
Trophoblast cells undergo ferroptosis in pregnancy-related diseases. HMGB1 participates in pathological ferroptosis. However, whether lipopolysaccharide (LPS) -mediated HMGB1 expression induces the ferroptosis of trophoblast cells and further spontaneous abortion (SA) remains unknown.

Methods
HMGB1 and ACSL4 expression were measured in villous tissues from 20 women with SA and 20 women with elective abortion. Human HTR-8/SVneo cells were treated with LPS to establish an in vitro abortion model. The hallmarks of ferroptosis including MDA, GSH, Fe2+ and ROS were detected using indicated assay kits.

Results
The levels of HMGB1 and ACSL4 in villous tissues from SA women were significantly higher than those in the normal control group. HMGB1 interacts with and stabilizes ACSL4 to promote the ferroptosis of trophoblast cells. Conversely, HMGB1 and/or ACSL4 inhibition attenuated LPS-induced trophoblast cells ferroptosis.

Conclusions
An HMGB1/ACSL4 axis is engaged in LPS-induced ferroptosis of trophoblast cells, and may be targeted to design treatments preventing SA.

Authors: Mishra A. K. , Sudarsan J. S. , Nithiyanantham S. 
Published: February 2025

Abstract
Residents and construction workers are exposed to such kind of toxic materials such as cement, paint, tiles, sand, bricks and etc., which may severely affect their health. The overall aim of this study is to assess the toxicity of these building materials in the case of Arjundhara municipality of Jhapa district (Province 1), Nepal. The toxicity assessment is done for the materials based on available material safety data sheet of A Class materials by performing ABC analysis. Health effects on construction workers and on residents are listed as per literature reviews. Likert 6 point scale is used to rate the health effects and it is analyzed through Relative Importance Index (RII). The construction workers have identified skin corrosion and irritation as the mostly occurring health hazard with a RII of 0.92. Asthma and then carcinogenicity are the least occurring health effects to the respondents with a RII score of both 0.32 each. For project 1, the most frequently occurring health effect is fatigue/dizziness with RII score of 0.76 and the least occurring is carcinogenicity with RII 0.29. For the second project which comprises of school children, headache is classified as the most frequently occurring health hazard with RII score of 0.63 and respiratory tract irritation least with RII 0.23. Similarly for project 3, residents have given highest score for fatigue/dizziness with RII 0.83 and least occurring as respiratory tract irritation 0.31.
Regulating precarious work: A paradigm shift
Authors: Quinlan Michael G , Rawling Michael J 
Published: February 2025

Abstract
Precarious work, the problems it poses in terms of labour standards/regulation, and remedies to this, have sparked considerable attention from researchers and policy-makers over the past three decades. This paper examines industrial relations (IR) legislation introduced by the Australian Labor government elected in 2022, and which, amongst other things, has addressed precarious work. These initiatives are placed in historical context, noting how essentially similar problems shaped IR regulation a century earlier. The article also examines the more immediate precursors to the legislation, by reviewing state and federal inquiries into precarious work and related issues in Australia from the 1990s onwards. Placing the new legislation into historical context enhances our understanding of the law and surrounding policy debates. The Albanese federal Labor government package of industrial relations laws introduced between 2022 and 2024 marked a paradigm shift from earlier measures. While these reforms are rooted in Australian institutions, law and industrial relations history, they provide an alternative policy template for addressing the problems wrought by neoliberalism on labour standards, especially if accompanied by synergistic reforms in other areas, such as immigration and economic policies promoting manufacturing.
Transitive mappings on the Cantor fan
Authors: BANIČ IZTOK , ERCEG GORAN , KENNEDY JUDY , MOURON CHRIS , NALL VAN 
Published: February 2025

Abstract
Many continua that admit a transitive homeomorphism may be found in the literature. The circle is probably the simplest non-degenerate continuum that admits such a homeomorphism. However, most of the known examples of such continua have a complicated topological structure. For example, they are indecomposable (such as the pseudo-arc or the Knaster bucket-handle continuum), or they are not indecomposable but have some other complicated topological structure, such as a dense set of ramification points (such as the Sierpiński carpet) or a dense set of end-points (such as the Lelek fan). In this paper, we continue our mission of finding continua with simpler topological structures that admit a transitive homeomorphism. We construct a transitive homeomorphism on the Cantor fan. In our approach, we use two different techniques, each of them giving two constructions of a transitive homeomorphism on the Cantor fan: one technique using quotient spaces of products of compact metric spaces and Cantor sets, and one using Mahavier products of closed relations on compact metric spaces. We also demonstrate how our technique using Mahavier products of closed relations may be used to construct a transitive function f on a Cantor fan X such that

$\varprojlim (X,f)$

is a Lelek fan.
Intimate image abuse offences: stakeholder perspectives of the effectiveness of the new offences in Hong Kong
Authors: Crofts Thomas 
Published: February 2025

Abstract
Intimate image abuse is a problem that is shared by many societies, and jurisdictions are learning from each other about how best to address this issue. In 2021 Hong Kong enacted four new intimate image abuse offences. Based on 15 semi-structured interviews with service providers and legal professionals, this study explores stakeholder perceptions of the effectiveness of the new offences in Hong Kong. Themes that emerged included why there was a need for specific offences, the impact that the new offences have had and whether further criminal law or non-criminal law reforms are necessary. A key finding from this research is that crafting offences to specifically target intimate image abuse is important to strengthen community awareness of the wrongfulness of intimate image abuse, enhance protection of victims and increase prosecutions. To be most effective, however, criminal law reform should be accompanied by holistic education and police training. Other non-criminal law reforms, such as working with providers and developing alternative complaints mechanisms, are also necessary to successfully combat intimate image abuse.
THE CHALLENGES TO ECONOMIC MEASUREMENT ARISING FROM INFLATION IN THE POST-PANDEMIC WORLD
Authors: Dixon Huw 
Published: February 2025

Abstract
The pandemic caused expenditure shares to vary more than usual, leading to serious ramifications when combined with the fact that the expenditure shares used to calculate CPI inflation are 1-2 years old. This caused a potential bias in the measurement of inflation. We also look at the cost-of-living crisis and found that the lags in updating the expenditure shares for energy and food led to an underestimate of inflation in 2022. Inflation also has a large effect on the measurement of the public sector deficit. With a high debt-GDP ratio and high inflation, there was a substantial inflation tax.

The Group-Basis of Political Behaviour among Minoritized Communities: The Case of LGBTQ+ Linked Fate and Sexual and Gender Minorities
Authors: Chan Nathan K. , Magni Gabriele 
Published: February 2025

Abstract
LGBTQ+ individuals often display consistent political behaviour despite being internally diverse. We theorize about the importance of group-based heuristics to understand this cohesiveness by proposing the concept of LGBTQ+ linked fate. First, we argue that LGBTQ+ linked fate is stronger among privileged individuals within the LGBTQ+ community (white, cisgender, gays/lesbians) and among those whose life experiences have made their LGBTQ+ identity salient. Then, expanding on social identity theory, we posit that individuals with greater LGBTQ+ linked fate are more likely to hold group-based political attitudes and voice these preferences through electoral participation. We provide support for these claims using a novel oversample of ∼2,000 LGBTQ+ Americans from the 2020 Collaborative Multiracial Post-Election Survey. We show that stronger LGBTQ+ linked fate is associated with higher voter turnout, leaning ideologically liberal, and identifying with the Democratic Party. This study contributes to understanding group identity, solidarity, and political behaviour among marginalized communities.
‘First record of Hsiungia pekingensis (Nematoda: Strongylidae) in North America: Morphological and molecular identification of a rare equine strongyle
Authors: Mohtasebi S. , Ahn S. , Rosa B. , Moyes K. , Kuzmina T. A. , Gilleard J.S. , Poissant J. 
Published: February 2025

Abstract
Equids are infected by a diversity of gastrointestinal nematode parasites, including 64 species of equine strongyle nematodes from19 genera. Despite numerous surveys of horse strongyles worldwide, certain geographic regions and rare species remain understudied. In 1964, a new species of equine strongyle, Cylicocyclus pekingensis, was described from a donkey in China. Subsequently, this species was recorded in horses from Kazakhstan and reclassified as Hsiungia pekingensis (K’ung and Yang, 1964), the only species in this genus. Since then, H. pekingensis has not been reported elsewhere, with limited knowledge on its distribution and phylogeny.
This study documents the first record of H. pekingensis in North America. Adult specimens were recovered from fecal samples of a domestic horse in Alberta, Canada, following treatment with ivermectin. Species identification involved detailed morphological examination, complemented with sequencing of the internal transcribed spacer 1 (ITS1), 5.8S rRNA gene, and the internal transcribed spacer 2 (ITS2) regions of the nuclear genome. Phylogenetic analysis indicated a close evolutionary relationship with species from Poteriostomum and Parapoteriostomum genera. Nemabiome ITS2 sequencing of a paired pre-treatment sample also detected the presence of H. pekingensis in the studied horse. Re-analysis of public equine nemabiome datasets further detected H. pekingensis in feral horses in Alberta, but not in other regions considered. This study expands the known distribution of this rare species and enhances our knowledge of its placement in the phylogeny of equine strongyles. Furthermore, our re-analysis of public nemabiome datasets highlights the value of this approach for studying the global distribution of parasite species.
Efficient relative localization and coordination system for unmanned ground vehicle formations under directed graph structure
Authors: Kabore Kader M. , Güler Samet 
Published: February 2025

Abstract
Onboard localization for multi-robot systems stands as a critical area of research with wide-ranging applications. This paper introduces an innovative framework for multi-robot localization, uniquely characterized by its onboard capability, thereby negating the dependency on external infrastructure. Our approach harnesses the inherent capabilities of each robot, enabling them to localize and synchronize their movements independently. The integration of cooperative localization algorithms with formation control mechanisms empowers a group of robots to sustain a predefined formation while following a linear trajectory. The efficacy of our framework is substantiated through comprehensive simulations and real-world experimental validations. We rigorously assess the system’s resilience to localization inaccuracies and external disturbances, demonstrating its adaptability and consistency in maintaining formation under diverse conditions. Furthermore, we explore the scalability of our approach, highlighting its potential to manage varying numbers of robots and its applicability in tasks such as collaborative transportation.
Kinematic design and analysis of a novel overconstraint walking mechanism
Authors: Selvi Ozgun , Cindioglu Cagri , Ider Sitki Kemal , Ceccarelli Marco 
Published: February 2025

Abstract
Walking mechanisms offer advantages over wheels or tracks for locomotion but often require complex designs. This paper presents the kinematic design and analysis of a novel overconstrained spatial a single degree-of-freedom leg mechanism for walking robots. The mechanism is generated by combining spherical four-bar linkages into two interconnecting loops, resulting in an overconstrained design with compact scalability. Kinematic analysis is applied using recurrent unit vector methods. Dimensional synthesis is performed using the Firefly optimization algorithm to achieve a near-straight trajectory during the stance phase for efficient walking. Constraints for mobility, singularity avoidance, and transmission angle are also implemented. The optimized design solution is manufactured using 3D printing and experimentally tested. Results verify the kinematic properties including near-straight-line motion during stance. The velocity profile shows low perpendicular vibrations. Advantages of the mechanism include compact scalability allowing variable stride lengths, smooth motion from overconstraint, and simplicity of a single actuator. The proposed overconstrained topology provides an effective option for the leg design of walking robots and mechanisms.
Improving the Lifelong Planning A-star algorithm to satisfy path planning for space truss cellular robots with dynamic obstacles
Authors: Dai Ye , Lv Weijian , Li Shikun , Zong Muyan 
Published: February 2025

Abstract
In this paper, a cellular robot for space trusses is structured so that it can perform tasks such as moving the truss and assembling the truss. There may be some spatial operating mechanisms on the space truss that cause obstacles to the robot’s movement, especially other mobile mechanical devices that are working, which are dynamic obstacles, so a suitable path planning for the robot is needed. In path planning, A-star algorithm has the advantages of efficient searching speed and good optimization effect, but it can’t deal with the path planning problem with dynamic obstacles, so this paper improves Lifelong Planning A-star (LPA-star) algorithm so that the improved algorithm satisfies the dynamic path planning task. Then a three-dimensional truss mathematical model is established, a dynamic obstacle environment is set up, the improved LPA-star algorithm is used for path planning, and the unimproved LPA-star algorithm and the improved A-star algorithm are used to compare with it. The simulation results show that in the environment set up in this paper, the optimal path length of the improved LPA-star algorithm is shortened by about 25% and the algorithm search time is shortened by about 55% compared with the improved A-star algorithm; while the unimproved LPA-star algorithm is unable to accomplish the dynamic path planning task. Therefore, the improved LPA-star algorithm can reduce the robot’s moving distance and time consumption.
Hericium erinaceus: A possible future therapeutic treatment for the prevention and delayed progression of Alzheimer’s disease? – A Narrative Review
Authors: Cornford Nisha , Charnley Margaret 
Published: February 2025

Abstract
At present, the treatment of Alzheimer’s disease involves only symptomatic medications which have continually demonstrated little efficacy, primarily due to the presence of biological barriers. Despite efforts, researchers have yet to discover a therapeutic treatment that delays neurodegenerative progression or restores associated Alzheimer neuropathological processes. For centuries, Hericium erinaceus (HE) has been used predominantly in Asian countries for its culinary and medicinal purposes, however, the use of this mushroom has not yet been utilised in western pharmacology. This review systematically investigates evidence pertaining to the use of HE as a potential future therapeutic treatment for the prevention and delayed progression of Alzheimer’s disease, by highlighting any fundamental neurotrophic and neuroprotective properties. In total, 3 human clinical trials and 13 animal-model studies were included for review. The use of HE demonstrated positive significant differences in results obtained from behavioural, histological, and biochemical assessments from both human clinical trials and animal model studies accentuating its utility for the improvement of cognitive function. In addition, erinacine A enriched HE appears to demonstrate the highest bioactive potency of all HE extracted compounds providing the greatest effects, while also evidencing transportability ease across biological barriers. In conclusion, evidence suggests that an intake of HE may be an appropriate and relevant future therapeutic treatment for the prevention and delayed progression of Alzheimer’s disease, however, continued research is necessary to provide increased significant evidence of this relationship, most likely through the increased quantity of human clinical trials.
The Weight of Lightness: Italian Opera and Parody in Congress Vienna
Authors: Babić Barbara 
Published: February 2025

Abstract
Recent scholarship at the crossroads of opera and Habsburg studies has emphasised the centrality of Italian opera within the political agenda of the Congress era (1814–22). It was a particularly effective means to project prestige, cosmopolitanism and belonging within a new geopolitical order, as the Kingdom of Lombardy–Venetia was integrated under the Habsburg Crown. While much attention has been given to performances of Italian opera at the Viennese court theatres, the role of suburban venues has so far been largely neglected. This article aims to demonstrate the ‘weight’ that the so-called ‘light’ genres carried within the cultural life of the capital and across the Habsburg lands. Two parodies written by Adolf Bäuerle for the Theater in der Leopoldstadt in Vienna – Tankredi (1817, music by Wenzel Müller) and Die falsche Prima Donna in Krähwinkel (1818, music by Ignaz Schuster) – serve as case studies for a discussion of the fluidity of genres, operatic voices and audiences, and the role of such singers as Gentile Borgondio, Angelica Catalani and Ignaz Schuster as ‘aural ambassadors’ of the Habsburg cultural project.
On a general matrix-valued unbalanced optimal transport problem
Authors: Li Bowen , Zou Jun 
Published: February 2025

Abstract
We introduce a general class of transport distances

$\mathrm {WB}_{\Lambda }$

over the space of positive semi-definite matrix-valued Radon measures

$\mathcal {M}(\Omega, \mathbb {S}_+^n)$

, called the weighted Wasserstein–Bures distance. Such a distance is defined via a generalised Benamou–Brenier formulation with a weighted action functional and an abstract matricial continuity equation, which leads to a convex optimisation problem. Some recently proposed models, including the Kantorovich–Bures distance and the Wasserstein–Fisher–Rao distance, can naturally fit into ours. We give a complete characterisation of the minimiser and explore the topological and geometrical properties of the space

$(\mathcal {M}(\Omega, \mathbb {S}_+^n),\mathrm {WB}_{\Lambda })$

. In particular, we show that

$(\mathcal {M}(\Omega, \mathbb {S}_+^n),\mathrm {WB}_{\Lambda })$

is a complete geodesic space and exhibits a conic structure.
Global well-posedness and Turing–Hopf bifurcation of prey-taxis systems with hunting cooperation
Authors: Tao Weirun , Wang Zhi-An 
Published: February 2025

Abstract
This paper is concerned with a predator–prey system with hunting cooperation and prey-taxis under homogeneous Neumann boundary conditions. We establish the existence of globally bounded solutions in two dimensions. In three or higher dimensions, the global boundedness of solutions is obtained for the small prey-tactic coefficient. By using hunting cooperation and prey species diffusion as bifurcation parameters, we conduct linear stability analysis and find that both hunting cooperation and prey species diffusion can drive the instability to induce Hopf, Turing and Turing–Hopf bifurcations in appropriate parameter regimes. It is also found that prey-taxis is a factor stabilizing the positive constant steady state. We use numerical simulations to illustrate various spatiotemporal patterns arising from the abovementioned bifurcations including spatially homogeneous and inhomogeneous time-periodic patterns, stationary spatial patterns and chaotic fluctuations.
