Electrical homeostasis of the inner mitochondrial membrane potential
Authors: Fahimi Peyman , Castanedo Lázaro A M , Vernier P Thomas , Matta Chérif F 
Published: January 2025

Abstract
The electric potential across the inner mitochondrial membrane must be maintained within certain bounds for the proper functioning of the cell. A feedback control mechanism for the homeostasis of this membrane potential is proposed whereby an increase in the electric field decreases the rate-limiting steps of the electron transport chain (ETC). An increase in trans-membrane electric field limits the rate of proton pumping to the inter-membrane gap by slowing the ETC reactions and by intrinsically induced electroporation that depolarizes the inner membrane. The proposed feedback mechanism is akin to a Le Chatelier’s-type principle of trans-membrane potential feedback control.
Beamforming based on DtN mapping
Authors: Qiu Yanping , Gao Siyu , Chen Qian , Zhang Gaoying , Zhang Yinquan 
Published: January 2025

Abstract
At present, the conventional beamforming is carried out by using the signal obtained from the pressure hydrophone, which is less than the vector hydrophone in the angular resolution. However, it is difficult for the vector hydrophone to make its application. Researchers have tried to use differential pressure hydrophones to increase the angular resolution, but it requires that the element spacing be much smaller than the wavelength. This paper proposes an idea to realize the reconstruction of acoustic pressure signals into the high-order gradient signal of acoustic pressure, which doesn’t require the element spacing to be much smaller than the wavelength. The method mainly uses the Rayleigh hypothesis, which considers that the elements are connected to each point. The establishment of DtN mapping matrix is for achieving high-order beamforming. The beamforming based on DtN mapping has a higher directivity index and orientation accuracy than conventional beamforming. It can also realize the superdirectivity of the end-direction.
Research on carbon dioxide power devices based on CFD
Authors: Cao Minglei , Chen Yanwei , Li Qi , Zhang Liang 
Published: January 2025

Abstract
A carbon dioxide power device is a high-potential gas power device. In order to study the effect of carbon dioxide pressure and flow state in the phase change chamber on the change law of load motion in a gas power device, the pressure before and after the load is read by the user-defined function in the simulation software. The motion change law of the load in the gun barrel is simulated by the dynamic grid technology to the initial pressure of different phase change chambers. The motion change law of the load with time and displacement is as follows: with the increase of the pressure in the phase change chamber, the exit velocity of the load approaches a linear change and gradually approaches the theoretical simulation calculation results. Afterwards, the feasibility of the calculation method and the correctness of the calculation results are verified by comparing the experimental and simulation results. Finally, the influence of the diameter of the phase change chamber on the work capacity of carbon dioxide is analyzed.
Comparative study on the effect of diffuser and semi-diffuser on energy loss for centrifugal pump
Authors: Duan Yongqiang , Wan Yang , Yan Yu , Li Guojun 
Published: January 2025

Abstract
Semi-diffusers are commonly employed for the compressor, but seldom for the pump. There is little research on the use of semi-diffusers for the pump and the effects of semi-diffusers have not been revealed. Entropy generation theory is for examining the effect of semi-diffusers on the energy loss characteristics of the pump in this paper. The findings demonstrate that semi-diffusers have a small impact on the entropy generation of semi-diffusers and impellers, but it can significantly reduce the energy losses of the volute as opposed to the diffusers. This is due to end clearance. End clearance increases the fluidity of the fluid between flow passage components. The ability of a semi-diffuser to reduce energy loss gradually increases as the flow rate increases. The semi-diffuser, relative to the diffuser, reduces the energy loss by a maximum of 1.1% under a low flow rate, by a maximum of 19.9% under a design flow rate, and by a maximum of 41.2% under a large flow rate.

Abstract
The use of high-Z sensors for scientific applications at
synchrotrons will gain more importance due to the upgrade of many
light sources around the world to diffraction limited light sources
for which the photon flux at high photon energies (above 30 keV)
will significantly increase. Especially when illuminated with high
photon fluxes, many established high-Z sensor materials like GaAs or
Cd(Zn)Te are known to suffer from charge (de-)trapping effects in
the bulk or at the contact interface which will ultimately lead to
polarization and afterglow effects in the sensor. Commercially
available high-Z sensors (Chromium-compensated GaAs, CdTe and
CdZnTe) have been investigated at the Material Science beamline of
the Swiss Light Source regarding their dynamic behavior when exposed
to photon fluxes between 106 ph/mm2·s and
≈ 5·1010 ph/mm2·s. In this work, the signal
stability during irradiation will be presented, and a follow-up
publication will discuss the afterglow.
Plant-inspired decentralized controller for robust orientation control of soft robotic manipulators
Authors: Pei Guanran , Hughes Josie 
Published: January 2025

Abstract
Due to the complexity of deformations in soft manipulators, achieving precise control of their orientation is particularly challenging, especially in the presence of external disturbances and human interactions. Inspired by the decentralized growth mechanism of plant gravitropism, which enables plants’ roots and stems to grow in the direction of gravity despite complex environmental interactions, this study proposes a decentralized control strategy for robust orientation control of multi-segment soft manipulators. This gravitropism-inspired decentralized controller was validated through simulations for convergence and robustness, and benchmarked against the traditional inverse Jacobian-based controller on a large-scale multi-segment soft manipulator. Experimental results demonstrate that the decentralized controller achieves comparable convergence and better control precision to the inverse Jacobian-based controller, while significantly outperforming it in disturbance rejection. Even in the presence of partial damage and human interaction, the decentralized controller provides robust control. This study provides a robust new approach for managing disturbances in complex environments, laying the foundation for further exploration of decentralized control strategies in soft robotics.
Soil moisture dominates the severe decline in gross primary productivity during a 2023–2024 compound heatwave-drought event over the Amazon

Published: January 2025

Abstract
The Amazon, the world’s largest tropical forest, plays a critical role in the global carbon cycle. It has a large carbon pool and acts as a major carbon sink. However, in 2023–2024, a compound heatwave-drought (CHWD) event (HD2023) hit the Amazon region, resulting in extreme temperatures and soil moisture deficits, threatening the region’s carbon sink capacity. Using advanced multisource satellite data and meteorological reanalysis, we quantified the impact of various climatic factors on vegetation productivity during HD2023 and analyzed its progression. Our findings showed that HD2023 led to a 530 Tg C decline in gross primary productivity (GPP) and 0.003 reduction in near-infrared reflectance of vegetation. The strongest phase of the event spanned 5 months, causing persistently high temperatures and reduced precipitation, leading to a continuous decline in soil moisture and marked reduction in GPP. The most severe decrease in GPP occurred in January 2024. The event originated in the northwest and gradually spread to the southeast. Soil moisture was the dominant factor in the decline of photosynthesis across vegetation types, whereas high solar radiation mitigated the impact of drought in evergreen broad forests and savannas. Moreover, the sensitivity of GPP to CHWD varied across vegetation types, ranking as grassland > savanna > evergreen broad forest. This study assessed the impact of HD2023 on regional carbon flux in the Amazon. As climate projections indicate future increases in climate extremes over the Amazon, it is important to identify the drivers of this impact on the carbon cycle of the Amazon.
Commitment Issues in the Naive Theory of Belief
Authors: Williams J Robert G 
Published: January 2025

Abstract
This paper investigates a puzzle about commitment. On the one hand, it is natural to hold that agents can be committed to propositions that they do not believe. On the other hand, because they are not logically omniscient, agents often have beliefs which are logically inconsistent. But then, since an inconsistent set of propositions entails every proposition, it seems that we have to hold that most or all agents are committed to every proposition. This consequence threatens to trivialize the idea of commitment. To resolve this puzzle about commitment, this paper draws on a structural similarity between theories of commitment and Robert Stalnaker’s account of belief. Stalnaker holds that agents can have fragmented beliefs: they can be related to multiple internally consistent but jointly incompatible belief states. When this happens, they can believe inconsistent propositions without believing every proposition as long as the inconsistent propositions are located in different fragments. the paper develops a similar strategy for thinking about commitment: beliefs can either be co-believed or not, and an agent is committed to the consequences of a set of beliefs only if those beliefs are co-believed.
Expressivism and Propositions
Authors: Stalnaker Robert 
Published: January 2025

Abstract
Expressivism is a theory about the status of evaluative judgments, including epistemic as well as ethical evaluation. The theory has long faced several technical problems, most prominently what has been called ‘the Frege-Geach problem’. Allan Gibbard gave what I thought was a definitive solution to those problems in his early work on what he called ‘normative logic’, but in later work he makes clear that his interpretation of this solution, and more generally his understanding of the commitments of expressivism, is different from what I was assuming. In this chapter I defend my interpretation of Gibbard’s expressivism against his, and then consider more briefly the application to epistemic norms.
Outline of an Object-Based Truthmaker Semantics for Modals and Propositional Attitudes
Authors: Moltmann Friederike 
Published: January 2025

Abstract
In this chapter, Friederike Moltmann describes and motivates an object-based truthmaker semantics for modals and propositional attitudes. Central to this approach is the idea of modal and attitudinal objects, like obligations and judgments, which have truth or satisfaction conditions. Moltmann envisions a truthmaker-type semantics compositionally assigning truth or satisfaction conditions to attitudinal objects. This allows her to assign truth conditions to modals and propositional attitudes which treat their prejacents (in the case of modals) or complementizer clauses (in the case of attitudes) as predicates of attitudinal objects. Moltmann describes several advantages of her framework as compared to traditional views like the relational analysis of propositional attitudes and the quantificational analysis of modals.
Unstructured Content
Authors: King Jeffrey C 
Published: January 2025

Abstract
In this chapter, Jeffrey C. King re-assesses the reasons for preferring a structured conception of content rather than an unstructured one. King surveys a number of objections to unstructured views, but he focuses his attention on the problem of unwanted equivalences—that on an unstructured view, propositions that are true in all the same possible worlds are identical. This seems to make bad predictions about the informativeness of utterances of sentences expressing necessary truths, such as “Hesperus is Phosphorus”, and about the differences in cognitive significance between sentences like “Hesperus is a planet” and “Phosphorus is a planet”. King surveys responses to these problems in the literature and argues that these responses are all beset with their own difficulties.
In Defence of Fregean That-Clause Semantics
Authors: Felka Katharina , Steinberg Alex 
Published: January 2025

Abstract
In this chapter, Katharina Felka and Alex Steinberg consider a problem for structured accounts of content articulated by Stephen Schiffer and Adam Pautz. The problem has to do with the idea of reference shift—that is, the idea that material embedded in the complementizer clauses of propositional attitude ascriptions must function semantically to refer to something other than what it refers to in unembedded contexts. Focusing in particular on Frege’s theory of content, Felka and Steinberg state the problem as follows: If ‘Hesperus’ in the sentence ‘Ben believes that Hesperus is a planet’ refers not to Venus but rather to the sense associated with the lexical item ‘Hesperus’, and if existential quantification works in the normal way, then the sentence ‘There is something such that Ben believes that it is a planet’ would seem to be true just in case there is a sense which Ben believes to be a planet. But, unless Ben is a peculiar individual indeed, he would never mistake a sense for a planet. So it seems that certain intuitively true sentences are predicted to be false by theories that posit reference shift. Felka and Steinberg suggest that the best response to this kind of argument for proponents of reference shift is to hold that the value of a variable relative to an assignment function shifts in propositional attitude ascriptions just like the value of any other kind of expression.
It’s Not All Roses and Defining and Measuring Community at Work
Authors: Boyd Neil 
Published: January 2025

Abstract
The chapter introduces the community experience framework and how scholars define and measure community at work. Community experiences are grounded in what organizations can give to employees (a need fulfillment notion) and what members of organizations can give to others and the workplace as a whole (a responsibility notion). A variety of metrics exist, and a few are starting to be used in organizational settings. Both qualitative and quantitative approaches can be employed: Qualitative approaches are useful toward understanding the deep meaning of community experiences, and quantitative techniques quickly reveal how a collective and its individuals experience community at work. By exploring these measures, one can develop a way to find out the current state of the community at work.
The Civic Movement and the Constitutionalist Turn
Authors: Argomaniz Javier 
Published: January 2025

Abstract
Chapter 4 focuses on the second Basque cycle of contention from the late 1990s. It describes the emergence of the civic (or “constitutionalist”) movement and examines how the catalyst for this new form of civil resistance was moral shocks caused by individual terrorist attacks. The civic movement constituted a new form of contentious politics that not only challenged ETA but also the ideology of Basque nationalism, which they regarded as the causal factor behind the violence. The chapter explores the constitutionalist use of diagnostic, motivational, and prognostic framing as they construct a new set of discourses to challenge ETA and bring coherence and identity to the movement. Their discursive work helped to introduce novel collective action frames such as the vigorous defence of liberal democratic values, the need to protect political freedoms and pluralism, and the dangers of nationalism as an ideology of division.
Intellectuals and the Crisis of Politics in the Interwar Period and Beyond
Authors: Trencsényi Balázs 
Published: January 2025

Abstract
This book offers a comprehensive analysis of modern European crisis discourses and focuses primarily on the interwar period, commonly described as a paradigmatic case of the crisis of modernity, and then follows through to the present day. It explores how the multiple crises of civilization, capitalism, social cohesion, liberalism, democracy, socialism, or the nation-state were conceptualized, how and to what extent these spheres were entangled, tracing also the multi-level dialogue of intellectuals, politicians, and experts who employed these discourses. The modern concept of crisis combines analytical and mobilizing functions and seeks to establish causal relationships, identify possible trajectories and alternative histories, and rearrange the discursive space by redefining the temporal and spatial coordinates of collective existence. Thus, discourses of crisis are rooted in various regimes of temporality and spatiality. Along these lines, the book provides a geographically and thematically inclusive re-narration of European intellectual history, weaving Eastern, Southeastern, Western, Northern, and Southwestern perspectives together. It de-centers the dominant narrative that takes Western European positions and developments as normative and adds the others as “exotic” peripheries. Within this broad canvas, the book pays special attention to two key contemporary contenders of liberal democracy: neoliberalism and populism. Drawing on, but also going beyond, the historical contextualization of these two streams, the book also explores how a reflective and self-critical liberal democratic political position might be delineated and defended in our current predicament, increasingly compared by observers to the interwar period, and often described as “polycrisis.”
Evolutionary adaptations in the limb morphology of tropidurid lizards in response to sandy environments
Authors: Tulli María J , Toyama Ken S 
Published: January 2025

Abstract
Different habitat types exert particular challenges to ecological performance, ultimately having a strong influence on the evolution of morphology. Although it is well known that external morphology can evolve under the selective pressure of habitat structure, the evolutionary response of internal morphological traits remains vastly unexplored. Here, we test for morphological divergence between arenicolous and nonarenicolous species in a clade of tropidurid lizards, considering external morphological proportions and limb muscle dimensions. We found that arenicolous species seem to have evolved internal and external morphological adaptations that separate them from other habitat specialists. Moreover, comparative analyses suggested that the traits that differed the most between arenicolous and nonarenicolous lizards might have evolved divergently towards different optima. Additionally, the axis of higher morphological divergence between arenicolous and nonarenicolous species represented an important proportion of the morphological diversity within our sample, indicating that the hypothetical adaptive divergence of internal and external traits has contributed significantly to phenotypic diversity. Our results show that evolutionary associations between morphology and habitat use can be detected on both external body proportions and muscle morphology. Moreover, they highlight the emergent importance of internal anatomical traits in ecomorphological studies, especially when such traits are directly involved in determining functional performance.
Confounding effects of socioeconomic status on the association between long-term PM2.5 exposure and mortality in Korea

Published: January 2025

Abstract

Background
This study assesses the national distribution of ambient fine particulate matter (PM2.5) exposure across socioeconomic status (SES) and its confounding on long-term PM2.5 mortality in Korea, aiming to minimize SES influence.

Methods
A nationwide cohort of 5% of Koreans, aged 30 or older, from 2007 to 2019, from the National Health Information Database, was analysed. PM2.5 exposure levels were estimated at the city level using the Community Multiscale Air Quality system. Mortality data were obtained from Statistics Korea. The study examined annual PM2.5 exposure by SES indicators and its confounding on mortality risks associated with PM2.5, using time-varying Cox proportional hazards models.

Results
The study followed 1 453 036 individuals from 2007 to 2019, totalling 17 760 227 person-years (PYs). The non-accidental (A00-R99), cardiovascular (I00-I99) and respiratory (J00-J99) mortality rates per 1000 PY were 7.6, 1.9 and 0.8, respectively. We observed a trend of decreasing PM2.5 exposure levels but increased mortality among medical aid beneficiaries, those with lower household incomes and those residing in neighbourhoods with a higher area deprivation index. When adjusting for these SES covariates, the long-term mortality effects of PM2.5 shifted in the direction of increased risk [hazard ratio (HR) for cardiovascular mortality in the unadjusted model = 0.968 (95% CI: 0.909–0.959); HR in the fully adjusted model = 1.053 (95% CI: 1.004–1.105)].

Conclusion
In regions where SES and PM2.5 concentrations are positively correlated, as in Korea, it is crucial to rigorously control for SES confounding to avoid underestimating the mortality effects associated with PM2.5.
The Transmission of Negative Nominal Interest Rates in Finland
Authors: Kwan Simon , Ulate Mauricio , Voutilainen Ville 
Published: January 2025

Abstract
Despite the implementation of negative nominal interest rates by several advanced economies in the last decade, there is still much we do not know about the effectiveness of this instrument. In this paper, we analyze the pass-through of the European Central Bank’s changes in the deposit facility rate to mortgage rates in Finland between 2005 and 2020. We use monthly data and three different empirical methodologies: event studies, high-frequency identification, and exposure-measure regressions. We provide robust evidence that there continues to be pass-through of a cut in the policy rate to mortgage rates even when the policy rate is in negative territory, but that this pass-through is smaller than when the policy rate is in positive territory.
