The dressing field method for diffeomorphisms: a relational framework
Authors: André J T François 
Published: June 2024

Abstract
The dressing field method (DFM) is a tool to reduce gauge symmetries. Here we extend it to cover the case of diffeomorphisms. The resulting framework is a systematic scheme to produce

-invariant objects, which has a natural relational interpretation. Its precise formulation relies on a clear understanding of the bundle geometry of field space. By detailing it, among other things we stress the geometric nature of field-independent and field-dependent diffeomorphisms, and highlight that the heuristic ‘extended bracket’ for field-dependent vector fields often featuring in the covariant phase space literature can be understood as arising from the Frölicher-Nijenhuis bracket. Furthermore, by articulating this bundle geometry with the covariant phase space approach, we give a streamlined account of the elementary objects of the (pre)symplectic structure of a

We give conceptually transparent expressions allowing to read the integrability conditions and the circumstances under which the bracket of charge is Lie, and the resulting Poisson algebras of charges are central extensions of the Lie algebras of field-independent (

We show that, applying the DFM, one obtains a

-invariant and manifestly relational formulation of a general relativistic field theory. Relying on results just mentioned, we easily derive the ‘dressed’ (relational) presymplectic structure of the theory. This reproduces or extends results from the gravitational edge modes and gravitational dressings literature. In addition to simplified technical derivations, the conceptual clarity of the framework supplies several insights and allows us to dispel misconceptions.
In-plane radiation pattern generated by large particles in dielectric substrates
Authors: Merlo Juan M , Carhart Madeleine H 
Published: June 2024

Abstract
In this work we present the study of in-plane radiation patterns generated by particles with dimensions larger than the excitation wavelength. We studied the in-plane radiation of Au structures focusing on two cases: particles and triangular crystals. We found that the radiation patterns were produced by the scattering of the excitation field at the bottom edges of the studied structures. In addition, we found the in-plane radiation decay exponentially due to the refractive index contrast between the substrate and superstate. Furthermore, we proved that in-plane radiation patterns originating from different structures can interact and generate interesting geometries. Finally, in addition to our experimental studies, we show numerically calculated simulations which agreed with our experimental results and thus confirmed our findings.
Influence of chemical treatment of Bamboo fibers on the vibration and acoustic characterization of Carbon/Bamboo fiber reinforced hybrid composites

Abstract
In the pursuit of sustainable materials, natural fibers are gaining attention because of their renewable nature and low environmental impact. However, their application in composites has been hindered by their hydrophilicity and non-homogeneity in the properties. To address these issues, chemical treatments such as Sodium Hydroxide and Potassium Permanganate have been utilized. This study explored the impact of chemical treatments on Bamboo fibers and their subsequent influence on the vibration and acoustic properties of Carbon/Bamboo fiber-reinforced hybrid composites. This study investigates the vibration damping and acoustic characteristics of hybrid composites, considering the synergistic advantages of Bamboo’s natural damping properties and Carbon fiber’s mechanical strength. The damping factor of Sodium Hydroxide treated Bamboo fiber reinforced hybrid composites is 34.55% higher than that of untreated Bamboo fiber reinforced hybrid composites. It is also 11.95% higher than that of Potassium Permanganate treated Bamboo fiber reinforced hybrid composites. The flexural modulus of untreated Bamboo fiber reinforced hybrid composites was 164.36% and 157.77% higher than that of Sodium Hydroxide treated and Potassium Permanganate treated Bamboo fiber reinforced hybrid composites, respectively. The effect of chemical treatment on the fiber properties were analysed using the FTIR spectrum. Acoustic characterization revealed that untreated Bamboo fiber composites have higher sound absorption coefficients at lower frequencies, whereas Sodium Hydroxide-treated composites have higher sound absorption coefficients at medium and high frequencies. The results indicated that chemical treatment enhanced fiber-matrix adhesion, reduced stiffness, and influenced the damping and acoustic performance of the hybrid composites.
Climate change mitigation from increased paper recycling in Sweden: conserving forests or utilizing substitution?

Published: June 2024

Abstract
Climate change mitigation by increased paper recycling can alleviate the two-sided pressure on the Swedish forest sector: supplying growing demands for wood-based products and increasing the forest carbon sink. This study assesses two scenarios for making use of a reduced demand for primary pulp resulting from an increased paper recycling rate in Sweden, from the present 72% to 78%. A Conservation scenario uses the saved primary pulp to reduce pulplog harvests so as to increase the forest carbon sink concomitant with constant overall wood product supply. In contrast, a Substitution scenario uses the saved primary pulp to produce man-made cellulosic fibers (MMCF) from dissolving pulp replacing cotton fiber, implying increased overall wood product supply. Our results suggest that utilizing efficiency gains in paper recycling to reduce pulplog harvests is better from a climate change mitigation perspective than producing additional MMCF to substitute cotton fiber. This conclusion holds even when assuming the use of by-products from dissolving pulp making and an indirect increase in MMCF availability. Hence, unless joint improvements across the value chain materialize, the best climate change mitigation option from increased paper recycling in Sweden would seemingly be to reduce fellings rather than producing additional MMCF.
Impact of global warming on labor productivity in the Chengdu-Chongqing economic circle, China
Authors: Wang Jiajin , Guo Jie , Wang Chunxue , Pang Yanmei 
Published: June 2024

Abstract
In recent years, the Chengdu-Chongqing Economic Circle (CCEC) has experienced frequent heat events, significantly impacting labor productivity. The CCEC is an important economic growth pole in western China. Therefore, an in-depth study of the impact of heat stress on labor productivity holds great significance for climate change adaptation and enhancing economic efficiency. Based on the relationship between the wet-bulb globe temperature (WBGT) and labor productivity of different industries, the labor productivity loss caused by heat in the CCEC was estimated using the observation data of the meteorological station and the projection results of the BCC-CSM2-MR model from the Coupled Model Intercomparison Project Phase 6 (CMIP6). The results showed that the impact of heat on the labor productivity of different industries in the CCEC mainly occurs from June to August, with the largest impact on agriculture, followed by industry, and the smallest impact on service sectors. Losses from heat stress to labor productivity in agriculture, industry, and services showed a significant increasing trend from 1980 to 2020 but a decreasing trend in comprehensive labor productivity loss. From 2020–2100, labor productivity losses in different industries due to heat stress show an increasing and then decreasing trend in the low emissions scenario, productivity losses in the medium emissions scenario are characterized by an increasing and then sustained change, and labor productivity losses in the high emissions scenario show a sustained increasing trend from 2020. By the end of the 21st century, the increase in labor productivity losses across different industries under the high emission scenario is approximately 15%–23%, and the large value center shifts slightly to the west. In most areas, the losses of agricultural, industrial, service, and comprehensive labor productivity exceed 45%, 32%, 20%, and 24%, respectively.

Published: June 2024

Abstract
Implant-associated infections, caused by the formation of biofilms especially antibiotic resistant organisms, are among the leading causes of orthopaedic implant failure. Current strategies to combat infection and biofilm focus on either inhibiting bacterial growth or preventing bacterial adherence that could lead to biofilm creation. Despite research on developing numerous antimicrobial orthopaedic devices, to date, no robust solution has been translated to the clinic. One of the key bottlenecks is the disconnect between researchers and regulatory agencies. In this review, we outline recent strategies for minimizing orthopaedic implant-associated infections. In addition, we discuss the relevant Food and Drug Administration regulatory perspectives, challenges. We also highlight emerging technologies and the directions the field that is expected to expand. We discuss in depth challenges that include identifying strategies that render implants antibacterial permanently or for a long period of time without the use of antimicrobial compounds that could generate resistance in pathogens and negatively impact osseointegration.
A single DC source, seven-level switched capacitor tripple boost inverter with fewer switches for renewable energy applications
Authors: Kumar Vinayak , Agarwal Ruchi 
Published: June 2024

Abstract
This article presents a new SSTB-MLI with 3 times voltage boosting capability for medium voltage applications with optimal efficiency. Single DC source MLI topologies are more appropriate for many applications, including grid applications and renewable energy (RE) conversion systems than multiple DC source MLI topologies. The ability of switched-capacitor multi-level inverters (SCMLIs) to raise voltage has made them more and more popular in recent years. LS-PWM technique is used for the switching scheme. Two capacitors are employed in SSTB topology to operate alternatively in charging and discharging states at the carrier frequency of this LS-PWM algorithm for making the levels of output voltage. Comparing this innovative topology to those documented in the literature. It can also minimise the number of switches and capacitors needed, their voltage stresses, and switching loss. Since the suggested topology includes built-in capacitor voltage balancing, no additional voltage balancing circuit is required. Applications requiring industrial drives as well as grid-connected and R, RL loads can employ the suggested architecture. Based on less TSV (total standing voltage), MSV (Maximum standing voltage), the number of components used, optimum efficiency 98.43%, and other factors, a comparative analysis is done between the existing topology and the proposed topology. Experimental data and thorough simulation are used to verify the suggested switched capacitor multilevel topology.
A modified invasive weed optimization for MPPT of PV based water pumping system driven by induction motor
Authors: Revathi V M , Subramani K , Krishnakumar S , Alawadi Ahmed Hussein , Senthil Kumar R , Malla Siva Ganesh 
Published: June 2024

Abstract
A novel approach called Modified Invasive Weed Optimization (MIWO) technique has been developed and combined with the Perturb and Observes (P&O) algorithm to enhance the extraction of maximum power from photovoltaic (PV) panels in the presence of partial shading conditions. The conventional P&O algorithm falls short in extracting the maximum power from PV systems under partial shading conditions due to the existence of multiple maximum points. In such scenarios, optimization techniques can be employed to search for the global maximum point. The proposed MIWO-based P&O algorithm updates the reference voltage to ensure that the PV system operates at the Maximum Power Point (MPP) based on the prevailing weather conditions. This MIWO based PV system is further fed to water pumping system. A PV-based water pumping system is utilized for both irrigation and domestic purposes. Additionally, a sensorless vector control-based induction motor is employed in this study to drive the pump. The objective of this research is to demonstrate the achievement of an efficient PV-based water pumping system without the need for battery storage. Various results based on MIWO are compared with PSO and GWO. The results are presented based on various water pumping applications and the availability of solar irradiance during rapid climate changes. MATLAB/Simulink simulations, along with hardware-based experiments, are provided to validate the effectiveness of the proposed method under both transient and steady-state conditions.
National Causes
Authors: Mueller Sean 
Published: June 2024

AbstractThis chapter analyses the causes of the extent of shared rule at the level of countries. It combines a paired comparison of the USA and Canada with a quantitative analysis of forty-two Organisation for Economic Co-operation and Development/European Union countries plus Bosnia and Herzegovina. Shared rule is higher in ‘coming-together’ federations with extensive linguistic diversity and extended degrees of de- or non-centralization. The chapter also identifies two resulting tensions: that in ‘staying-together’ federations with high levels of self-rule, calls will inevitably arise for greater shared rule too; and that in systems with already high levels of shared rule, regional influence over state-wide decisions might not always work as intended and/or only to the profit of some regions, for instance those aligned with the state-wide majority or richer ones.
Was the Enlightenment a Social Practice?
Authors: Clark J C D 
Published: June 2024

Abstract
The Enlightenment has recently been taken out the hands of ‘philosophers’ by historians who stress social practice, especially the ‘scientific revolution’ and (an idea deriving from Jürgen Habermas) the ‘public sphere’. This chapter offers a reconsideration of the Royal Society through a close reading of Thomas Sprat’s programmatic account of it (1667), and a detailed reconsideration of the work of Habermas. It provides substance to these methodological enquiries by investigating two seemingly related institutions, the English coffee house and the French salon. Both emerge as much more various, and not to be explained by the conventional historical formulae. Finally, it considers recent scholarship on the theme of spreading literacy and concludes that it too does not establish the validity of the concept ‘the Enlightenment’.
Was the Enlightenment Invented in France?
Authors: Clark J C D 
Published: June 2024

Abstract
Chapter 2 addresses the four greatest French figures conventionally enlisted in the ranks of the Enlightenment—Voltaire, d’Alembert, Diderot, and Rousseau—and highlights both their early preoccupations and their conflicts (rather than their sociable co-operation). The chapter examines the work often (but, it argues, wrongly) held to be the embodiment of the Enlightenment, the Encyclopédie. It concludes that religious scepticism rather than social or political reform was at the heart of these four men’s concerns; it explains Voltaire’s limited reception in England; and it stresses the significance of the divisions between these four as well as of the conflict between Rousseau and Hume.
Why Could Even Leading Reformers in the Age of Revolution Not Conceptualize ‘the Enlightenment’?
Authors: Clark J C D 
Published: June 2024

Abstract
To explain historically why something did not happen is far harder than to explain why something else did. Chapter 5 confronts this difficulty in arguably its most difficult location, the case of three leading British intellectuals of the late eighteenth century: Richard Price, Joseph Priestley, and Thomas Paine. It accounts for the absence of this later concept in their writings in terms of their theology (also a source of division between them) and the barriers their theologies placed in the way of formulating teleological goals of secular reform. As such, it links the technical theological positions of Arianism, Socinianism, and Deism with their practical consequences in the world of politics in the ‘Age of Revolutions’.
Was the Enlightenment Invented in America?
Authors: Clark J C D 
Published: June 2024

Abstract
The conventional history of the Enlightenment as an international movement inevitably led to an interpretation of the American Revolution as the first to fall of a line of dominoes, naturally leading on to the French. Chapter 6 examines how this model came into existence through a critical review of the writings of Richard Price, its chief anglophone framer. It argues instead that he had little knowledge of the inner life of the American colonies, but saw events through the eyes of his Protestant Nonconformist co-religionists there. This perspective Price then applied to events in France in 1789, a misunderstanding that his correspondent in Paris, Thomas Jefferson, did nothing to correct.
Did Socialists Recognize the Enlightenment?
Authors: Clark J C D 
Published: June 2024

Abstract
Karl Marx was a German historian of German philosophy who early in his life occasionally used the term die Aufklärung, but soon discontinued this usage when he adopted political economy as his explanatory framework. His English followers, including Henry Hyndman and the Fabians, produced sophisticated economic explanations of the necessary course of social evolution without reifying or drawing on an eighteenth-century Enlightenment. Robert Owen, often hailed as the father of English socialism, emerges here as similarly unindebted both to Marx and to any eighteenth-century movement. Socialism rested on its own historical and economic foundations. Not until the work in the 1950s of a former economics don, Anthony Crosland, did British socialism begin to orient itself away from an austere Marxist model and towards what is now called ‘identity politics’; only now did ‘enlightenment’ begin to enter into the vocabulary of the British Left.
Was ‘the Enlightenment’ Invented in Germany?
Authors: Clark J C D 
Published: June 2024

Abstract
Chapter 10 argues that German influences were important in introducing the term die Aufklärung into English discourse, but that this happened slowly, and with difficulties of translation. Chapter 10 provides a detailed survey of the German history of German philosophy from the early eighteenth century to the late nineteenth. It places Kant in the middle of this intellectual tradition, but argues that the conventional attribution to him of a leading role in launching a movement is a retrospective misunderstanding. Nevertheless, German philosophers and historians of philosophy did work out an idea of die Aufklärung as a chronological period and eventually attributed to it a normative and purposeful set of social meanings. From shortly before 1914, this usage began to be adopted by British and American philosophers also. But this did not justify the invention of ‘the Counter Enlightenment’, which is here attributed chiefly to the scholarly shortcomings of Isaiah Berlin.
Was There an ‘Enlightenment Project’?
Authors: Clark J C D 
Published: June 2024

Abstract
When ‘the Enlightenment’ was finally conceptualized in anglophone usage, it was taken up and employed to forward a number of reforming causes. Three are examined here. The first crusade, for parity of esteem for agnostics and atheists, is notable for having almost but not quite coined the concept, and this may have limited its effectiveness. The second, to defend Jews from Nazi persecution, engaged with the lives and works of a remarkable generation of German Jewish émigré intellectuals, whose contributions to Enlightenment studies are traced. The third has been a crusade for parity of esteem for people of alternative sexualities; but whether ‘the Enlightenment’ acted in that crusade as an effective analysis, or was appealed to as an emphasizer the historical truth of which needed no proof, is open to debate.
Conclusion
Authors: Clark J C D 
Published: June 2024

Abstract
This book responds to the breakdown of modernism and to the problems of postmodernism. Instead of modernism’s self-evident truths and over-determined outcomes, it illustrates on the territory of intellectual history the force of contingency and the precariousness of things. The Conclusion ties together these arguments to make clear that ‘enlightenment’ was a metaphor, ‘the Enlightenment’ a concept; and it reflects on the relation between these two figures of speech in historical explanations. It anticipates objections that may be made to the arguments of the book, and offers defences. Finally it suggests that emancipation from the force of hitherto inescapable concepts offers a route to intellectual liberation.
Liberal Anxieties and Ideological Adjustment in Global Development
Authors: Alami Ilias , Dixon Adam D 
Published: June 2024

Abstract
This chapter shows that the new state capitalism is triggering complex ideological adjustments, focusing in particular on official discourses, practices, and agendas of global Development. Empirically, the analysis relies upon a close reading of policy documents released by multilateral development actors such as the International Monetary Fund, the World Bank, the Organization for Economic Co-operation and Development, and the G-20. The new state capitalism is prompting these liberal regulative agencies to react and adapt. This has taken the form of a strategic discursive and ideological adjustment involving a certain re-legitimation of the place of the state in Development, and a limited embrace of its role as promoter, supervisor, investor, and owner of capital. The articulation of this new vision of the state in Development plays a fundamentally political role: it attempts at minimizing the multiple risks and dangers that are perceived to be associated with the current rise of state capitalism. This includes minimizing the potential for the political ‘use’ of state-capital hybrids, which would risk creating a spiral of protectionism, or what the IMF now refers to as ‘geoeconomic fragmentation’. This also includes controlling the proliferation of state-capital hybrids and making sure that they assume liberal forms (especially in developing countries). Finally, this involves ensuring that their increasing cross-border activities create the least political frictions possible. Put differently, this discursive re-legitimation of the state, and its limited embrace of state-capital hybrids, is a way of addressing liberal anxieties regarding the new state capitalism and its potential geoeconomic consequences.
