Authors: He J. , Ren Y. , Sun Y. , Wu K. , Xiong Z. , Xiao J. 
Published: May 2024

Abstract
Springback is the most common quality defect in roll forming. It is difficult to control springback efficiently because the forming process is very complex and difficult to analyze. This paper proposes a data-driven springback control method that can adaptively adjust process parameters to minimize springback. Firstly, a digital twin model was established for efficiently collecting equipment data, formed part data, and remote equipment control. Then, based on gathered springback data considering different sheet widths, materials, uphill volumes, and roll gaps, a high-precision springback prediction model was constructed using the SAPSO-SVR algorithm. Lastly, building upon the prediction model, optimization models were developed using bat algorithm, enabling the system to automatically adjust process parameters based on optimization results when forming different sheets.The experimental results show that after optimization, the springback at the two corners of the hat-shaped part is reduced by 36.8% and 14.3% respectively. Experimental findings initially demonstrate the efficacy of this approach in controlling springback across sheets of diverse materials and varying widths. The proposed adaptive springback control method significantly enhances production efficiency and forming quality, driving the intelligent advancement of sheet metal roll forming technology.

Abstract
In metal forming, such as stamping of automotive parts, unsupervised machine learning models offer a transformative approach to real-time quality control, especially when labelled data are scarce. Leveraging clustering algorithms and autoencoders, we develop a machine learning system capable of autonomously monitoring sensor data and identifying deviations suggestive of potential defects. The system offers multiple benefits including rapid intervention, reduced part defects and lower stoppages required to rectify defects. The use of unsupervised machine learning models also adds a layer of adaptability, allowing the system to continually refine its understanding of what constitutes a ‘normal’ operation. Empirical evaluation demonstrates the potential of the developed system in detecting anomalies in production data collected from dynamic automotive manufacturing environments.
Wrinkling Determination in Sheet Metal Loaded by Shear Stresses
Authors: Magrinho J.P.G. , Santos J.A.O. , Silva M.B. 
Published: May 2024

Abstract
Lightweight concept approach in sheet metal forming requires, among others, thickness reduction and geometry complexity. This combination dramatically promotes the wrinkling occurrence, which can be considered as one of main failure mode that toolmakers must consider. The sheet metal wrinkling determination research usually considers the wrinkling in flange and conical area of a cylindrical cup. For complex geometries the loadings are more diverse than in the deep drawing of a cylindrical cup involving shear stress states. In this context, the present work proposes the application of two different wrinkling determination methodologies in an experimental sheet metal specimen loaded by shear in an aluminum alloy. One of the methodologies involves geometrical parameters to trigger the onset of wrinkling and the other methodology is physically based and considers the evolutions of the in-plane minor strain and its strain rate. The experimental formability test requires a dedicated clamping apparatus to allow its kinematics to be similar to a tensile test. Results allowed the identification of the stress state that triggered the wrinkling occurrence, and the determination of the critical strains that allow plotting the wrinkling limit curve of the sheet material.

Published: May 2024

Abstract
The electrophysical impact on metals introduces a novel optimization avenue for roll forming. This study explores the influence of different electric pulse parameters (peak current and frequency) on the roll forming behavior of DP780 high-strength steel. Through electric pulse-assisted tensile, bending, and roll forming experiments, coupled with microstructure and fracture morphology analyses, the study comprehensively assesses the impact of electric pulses on the mechanical properties and springback mechanism of DP780 sheets. Results indicate that electric pulses reduce deformation resistance and enhance the plasticity of DP780 sheets by repairing defects, promoting dislocation slip, and changing the fracture form of the material. Moreover, electric pulses effectively inhibit springback in roll forming, particularly at larger bending angles and under specific E-pulsing parameters. This is attributed to the promotion of residual stress release by electric pulses, leading to a reduction in springback. In conclusion, electric pulse assistance optimizes the roll forming process of DP780 high-strength steel, evidenced by decreased deformation resistance, improved material plasticity, and effective suppression of springback. These findings open up a new optimization pathway for sheet metal forming.
Electromagnetic surface waves guided by the interface of a metal and a tightly interlaced matched ambidextrous bilayer

Published: May 2024

Abstract
The existence and characteristics of electromagnetic surface waves (ESWs) whose propagation is guided by the planar interface of metal and a tightly interlaced matched ambidextrous bilayer (TIMAB) were theoretically investigated, a TIMAB being a periodic unidirectionally nonhomogeneous material whose unit cell consists of one period each of two structurally chiral materials that are identical except in structural handedness. Thus, the structural handedness flips in the center of the unit cell. A canonical boundary-value problem was formulated and a dispersion equation was solved, the ESWs being classified as surface-plasmon-polariton (SPP) waves. Flipping the structural handedness once in the unit cell can greatly enhance the number of possible SPP waves, one or more of which may be superluminal.
De haeretico comburendo
Authors: Dzelzainis Martin 
Published: May 2024

Abstract
Andrew Marvell’s Mr. Smirke (1676) has never been properly considered in relation to the controversy in Parliament between 1675–7 over the abolition of the writ de haeretico comburendo by which the secular power punished the spiritual crime of heresy. Furthermore, in 1676, Marvell’s patron, the Earl of Anglesey, engaged in a prolonged discussion of Thomas Hobbes’s An Historical Narration of Heresie, and the Punishment Thereof with Bishop Thomas Barlow in Oxford. Once viewed in this light, some hitherto puzzling aspects of Marvell’s work begin to make sense—in particular, the vexed question of the date of composition of the Short Historical Essay, Concerning General Councils, Creeds, and Impositions, in Matters of Religion—the second main component of Mr. Smirke. More broadly, to do so is to cast doubt on the widely held view held that Mr. Smirke registers Marvell’s transition from mainstream Puritan to freethinker and even deist.
A Journey out of London, 1802
Authors: Constantine Mary-Ann 
Published: May 2024

Abstract
This chapter takes a single manuscript source, a notebook recording a journey made on foot by the radical Unitarian Welsh poet and stonemason Edward Williams (better known as Iolo Morganwg) in the early summer of 1802. It traces the route taken by Williams from London to Glamorgan via Birmingham and down through the Welsh Marches, to explore the concept of border territory in relation to pedestrianism and political identity. Drawing on work by John Barrell, Robin Jarvis, Mark Philp, and Nigel Leask, it shows how Williams’s encounters with people, buildings, and the border landscapes of Radnorshire and Breconshire produce a shifting, anxious, and occasionally neurotic interior monologue in which events and memories from the previous revolutionary decade surface in disturbing ways.
Visionary Journeys
Authors: Constantine Mary-Ann 
Published: May 2024

Abstract
This chapter contextualizes Welsh tours in relation to religion, past and present. Moving across Glamorgan into south-west Wales, it explores some of the religious centres of power in the Middle Ages (Neath Abbey, St David’s Cathedral), and their status as ruins and memorials in Welsh landscapes of the eighteenth and early nineteenth centuries. It considers the modern ‘pilgrimage’ of visiting such sites and examines their potential to develop new meanings in contemporary contexts, in particular with regard to religious gatherings and the Methodist revival. It introduces the early unpublished Welsh tours of a ‘visionary’ antiquarian, Richard Gough, and discusses the nature of pilgrimage in the work of the Fishguard-based lawyer and writer Richard Fenton.
Attempts to Describe Hafod
Authors: Constantine Mary-Ann 
Published: May 2024

Abstract
This chapter focuses on tourist accounts of the picturesque west Wales estate of Hafod, created by Thomas and Jane Johnes in the uplands of Ceredigion in the decades between 1785–1815. It analyses the complex semi-entrepreneurial relationship which existed between Johnes and the artists and writers who came to depict the house and grounds, and sees Hafod as something akin to a picturesque ‘performance’. Accounts by William Gilpin, George Cumberland, James Smith, and Richard Warner are discussed in relation to the period’s strategies for representing ‘Nature’. Warner’s account is singled out for its detailed description of the nearby lead-mines, and the chapter closes with observations on the pollution of the river Ystwyth, which formed the sinuous visual centrepiece of the Hafod estate.
Revolutionary Philanthropy
Authors: Finkel Stuart 
Published: May 2024

Abstract
This book provides a comprehensive overview of the origins and development of aid to political prisoners and exiles in nineteenth-century Russia, examining how a series of first informal groupings and then organized societies emerged from the nascent revolutionary movement of the 1870s–1880s. While framed as philanthropic, these activities were always also political, having provocatively appropriated the name and humanitarian mission of the Red Cross illicitly to assist enemies of the tsarist state. Such efforts came to provide a unifying thread for the notoriously fractious and fragmented radicals and linked these small and isolated groups to wider circles of sympathizers, both at home and abroad. The unjustly persecuted political prisoner served as a powerful synecdoche for the tyranny of the autocratic state, while alleviating the fate of these “victims of the struggle for liberty” came to be legible as an indisputably noble act across political and even national boundaries. Revolutionary Philanthropy posits that the groupings and organizations that undertook aid to political prisoners and exiles emerged through gradually accrued shared practices within a series of constantly evolving, overlapping domestic and international personal and political networks. In bringing together two seemingly incompatible modes of social action—radical politics and philanthropy—these “Red Cross” activities came to form a vital connective tissue across party and ideological lines. Within Russia, this engaged a significantly broader circle of liberals and politically uncommitted supporters, while revolutionary émigrés presented the Western public with a captivating narrative of heroic martyrs unjustly suffering for the cause.
Introduction
Authors: Finkel Stuart 
Published: May 2024

Abstract
The Introduction contextualizes the long history of aid to political prisoners and exiles in Russian and Soviet history from the mid-nineteenth century to the present, providing an overview of its long and varied legacy and highlighting those features of political aid that have endured. It notes that already by the turn of the twentieth century activists and émigrés had cultivated both domestic and Western audiences for politically charged humanitarian appeals. It then lays out the book’s major arguments and conceptual frames, including the origins and development of aid to political prisoners as a manifestation of gradually unfolding, evolving, overlapping personal networks; “political philanthropy” as an apparently paradoxical modality that allowed for broader involvement in the radical movement; and the appropriation of the language of humanitarianism to draw attention to and foment sympathy for unjustly suffering “heroic martyrs.” It also foreshadows the book’s quasi-prosopographical tracking of the differential fates of those who became involved in various types of political aid activity in the late nineteenth century.
PIPET: predicting relevant subpopulations in single-cell data using phenotypic information from bulk data

Published: May 2024

Abstract
Single-cell RNA sequencing has revealed cellular heterogeneity in complex tissues, notably benefiting research on diseases such as cancer. However, the integration of single-cell data from small samples with extensive clinical features in bulk data remains underexplored. In this study, we introduce PIPET, an algorithmic method for predicting relevant subpopulations in single-cell data based on multivariate phenotypic information from bulk data. PIPET generates feature vectors for each phenotype from differentially expressed genes in bulk data and then identifies relevant cellular subpopulations by assessing the similarity between single-cell data and these vectors. Subsequently, phenotype-related cell states can be analyzed based on these subpopulations. In simulated datasets, PIPET showed robust performance in predicting multiclassification cellular subpopulations. Application of PIPET to lung adenocarcinoma single-cell RNA sequencing data revealed cellular subpopulations with poor survival and associations with TP53 mutations. Similarly, in breast cancer single-cell data, PIPET identified cellular subpopulations associated with the PAM50 clinical subtypes and triple-negative breast cancer subtypes. Overall, PIPET effectively identified relevant cellular subpopulations in single-cell data, guided by phenotypic information from bulk data. This approach comprehensively delineates the molecular characteristics of each cellular subpopulation, offering insights into disease-related subpopulations and guiding personalized treatment strategies.

Robustness of response-adaptive randomization
Authors: Ye Xiaoqing , Hu Feifang , Ma Wei 
Published: May 2024

ABSTRACT
Doubly adaptive biased coin design (DBCD), a response-adaptive randomization scheme, aims to skew subject assignment probabilities based on accrued responses for ethical considerations. Recent years have seen substantial advances in understanding DBCD’s theoretical properties, assuming correct model specification for the responses. However, concerns have been raised about the impact of model misspecification on its design and analysis. In this paper, we assess the robustness to both design model misspecification and analysis model misspecification under DBCD. On one hand, we confirm that the consistency and asymptotic normality of the allocation proportions can be preserved, even when the responses follow a distribution other than the one imposed by the design model during the implementation of DBCD. On the other hand, we extensively investigate three commonly used linear regression models for estimating and inferring the treatment effect, namely difference-in-means, analysis of covariance (ANCOVA) I, and ANCOVA II. By allowing these regression models to be arbitrarily misspecified, thereby not reflecting the true data generating process, we derive the consistency and asymptotic normality of the treatment effect estimators evaluated from the three models. The asymptotic properties show that the ANCOVA II model, which takes covariate-by-treatment interaction terms into account, yields the most efficient estimator. These results can provide theoretical support for using DBCD in scenarios involving model misspecification, thereby promoting the widespread application of this randomization procedure.
From one-child policy to three-children initiative: a feminist critique of the population planning policies in China
Authors: Zhang Ming , Zhang Chi , Liu Yuxin 
Published: May 2024

Abstract
This article examines the continuity of heteropatriarchal discourse within China’s population policies, focusing on the transition from the one-child policy to the current three-children initiative, and women’s responses to these official narratives. Through the lens of Foucauldian bio-politics, the study explores how discursive practices surrounding family planning policy are manipulated to sustain authoritarian rule, linking it with loyalty to the state and fostering an anti-feminist support base that attributes collective feminist movements to “excessive education.” The “optimization” of the family planning policy is analyzed as a discursive construct that conceals dehumanizing policies reducing women to mere reproductive machines, and portraying children solely as future labor force. This paper argues that the digital feminist movement in China is sustained by women’s constant engagement with, and resistance against official narratives that co-opt feminism to serve the state’s bio-political agenda of managing and controlling the female body.
Special Interest Groups Versus Voters and the Political Economics of Attention
Authors: Balles Patrick , Matter Ulrich , Stutzer Alois 
Published: May 2024

Abstract
We investigate whether US House representatives favour special interest groups over constituents in periods of low media attention to politics. Analysing 666 roll calls from 2005 to 2018, we show that representatives are more likely to vote against their constituency’s preferred position the more special interest money they receive from groups favouring the opposite position. The latter effect is significantly larger when less attention is paid to politics due to distraction by exogenous newsworthy events like natural disasters. The effect is mostly driven by short-term opportunistic behaviour than the short-term scheduling of controversial votes in periods with high news pressure.
Urgent Need to Understand and Prevent Gonococcal Infection: From the Laboratory to Real-World Context

Published: May 2024

Abstract
Neisseria gonorrhoeae is widespread globally. Primary prevention is unsuccessful and antimicrobial resistance threatens optimal management. There is no specific vaccine and natural infection studies show that N gonorrhoeae can avoid and suppress immune responses. In addition to extensive variation in expression and specificity of many gonococcal surface antigens, it induces a robust inflammatory response through the Th17 pathway with a large influx of neutrophils and inflammatory cytokines but evades macrophages. The Th1- and Th2-mediated response is suppressed, resulting in low, short-lived antibody titers. Real-world evidence suggests that gonorrhea cases are reduced among recipients of Neisseria meningitidis group B vaccines containing outer membrane vesicles (OMVs). Although the first randomized trial of an OMV-containing MenB vaccine against N gonorrhoeae infection did not show statistically significant vaccine efficacy, ongoing trials might shed further light. Several candidate vaccine antigens for a gonococcal-specific vaccine are being evaluated preclinically but only one has reached clinical trials.

Abstract
Trachoma is targeted for elimination as a public health problem worldwide by 2030. In Nigeria, elimination activities are implemented at the local government area (LGA) level. They started in 2002 by conducting baseline population-based prevalence surveys (PBPSs), which continued in a systematic manner with engagement from the Global Trachoma Mapping Project in 2013, and subsequently Tropical Data. The results led to the development of Nigeria's first trachoma action plan and its subsequent revision with additional information. Following 449 baseline PBPSs, 122 LGAs had an active trachoma prevalence above the elimination threshold, requiring interventions, while 231 LGAs required community-based interventions for trichiasis management. By 2021, &gt;34 million antibiotic treatments had been provided in 104 LGAs, with 89 LGAs eliminating active trachoma. Nationally, water and sanitation coverages increased by 3% and 18%, respectively, in 7 y. Systematic trichiasis case finding and management were carried out in 231 LGAs, resulting in the management of 102 527 people. Fifty-four LGAs decreased trichiasis prevalence unknown to the health system to &lt;0.2% in persons ≥15 y of age. Where this elimination prevalence threshold was reached, trichiasis services were transitioned to routine eye/healthcare systems. Such progress relied on strong leadership and coordination from the national trachoma program and tremendous support provided by partners. Attaining elimination of trachoma as a public health problem in Nigeria by 2030 is feasible if funding support is sustained.
