Hegel as a ‘backward-looking prophet’?: Kierkegaard’s critique of Hegel’s philosophy of history
Authors: Hodel Jonas 
Published: November 2024

Abstract
Kierkegaard presents his critique of a Hegelian philosophy of history in the works of his Climacus pseudonym, the Philosophical Fragments and the corresponding Concluding Unscientific Postscript. It has been contested whether he addressed his arguments toward Hegel directly. In this paper, I argue that these arguments are systematically pertinent to central issues both of Hegel’s as well as any other philosophical engagement with history. To make this point I proceed in three steps. First, the basic outlines of Hegel’s philosophy of history are given concerning its exact subject matter, what the aim of history is, and whether the reason inherent in it allows us to conceive of historical events as necessary. Second, I will show that, though agreeing with Hegel on some points, Climacus holds that we can ascribe neither a determinist nor a conceptual kind of necessity to historical events. Finally, I will expand on Climacus’s account of radical metaphysical contingency and its ethical implications which prompt some objections against philosophy of history in general.
Sociolinguistics, memory studies, and the dynamics of interdisciplinarity
Authors: Rampton Ben , Van de Putte Thomas 
Published: November 2024

Abstract
This article uses a dialogue between memory studies (MS) and ethnographic and interactional sociolinguistics (EIS) to explore the dynamics of interdisciplinarity. MS focuses on the social remembering of high-profile and often traumatic events, and this is relevant to EIS's growing interest in (in)securitization. MS is increasingly keen to explore everyday practices of remembering in interscalar analyses, and EIS’ expertise in the study of mundane communication can provide essential support. But there are major differences in their focal concerns and analytical cultures, as well as in their approaches to interdisciplinarity. This generates asymmetries in their exchange, which we illustrate with studies from Oświęcim/Auschwitz (MS) and Cyprus (EIS). By mapping these differences and highlighting collaborative data sessions as a practical arena for building relationships, the article seeks to deepen our understanding of interdisciplinarity and facilitate its practice.

Published: November 2024

AbstractThis study aims to develop an absolute model of contemporary Vertical Crustal Movements (VCM) and Vertical Land Movements (VLM) in an area of Poland based on GNSS solutions. Velocities at permanent stations were subjected to geological, tectonic, hydrological and mineral information analyses. Reliability analysis and estimation of velocities at individual GNSS stations, comparative analysis of results and spatial analysis were carried out. Vertical velocities were determined using four computational strategies. Daily satellite data in the ITRF2014 system collected from permanent GNSS stations of the Polish part of the ASG EUPOS system were obtained from the Polish Main Office of Surveying and Cartography. All the data were from the 2011 to 2021 time period (approx. 11 years) and obtained in Rinex format. Time series from the Precise Point Positioning (PPP) solution calculated using GipsyX software were used. The absolute vertical crustal velocities obtained for Poland mostly vary between +1.0 and −1.0 mm/yr, which is 95% of the values obtained within local extremes. This region of Poland can be considered tectonically stable and the developed VCM model correlates with the geological and tectonic structure of the region. Taking into account the influence of tectonics, geology, hydrology and location of mineral resources has allowed better interpretation of vertical velocities and correction of the associated model. The proposed computational strategy based on combining data sets developed by different methods gave good results.

AbstractSeismic imaging is one of the most powerful tools available for constraining the internal structure and composition of planetary bodies as well as enabling our understanding planetary evolution, geology, and distribution of natural resources. However, traditional seismic instrumentation can be heavy and voluminous, expensive, and/or difficult to rapidly deploy in large numbers. Distributed acoustic sensing (DAS) provides a promising new alternative given the ease of deployment, light weight and simplicity of fiber optic cables. However, the feasibility and best operational practices for using DAS for planetary exploration are not well‐known. We examine the use of DAS with surface deployed fiber for planetary near‐surface seismic exploration at two lunar geophysical analogue sites in San Francisco Volcanic Field. We compare DAS recordings to 3‐component seismometer recordings and geophone shot recordings and determine empirical response functions for the DAS system with respect to the 3‐component recordings. Shot sections of DAS and traditional seismic equipment compare well visually, with similar moveout of identifiable phases. DAS records first arrivals in good agreement with seismometers making them suitable for refraction work. Multichannel analysis of surface waves is performed on DAS records to estimate shallow shear velocities. The DAS has high spectral coherence with the horizontal components of ∼0.7 in the frequency band of the seismic shot energy. The empirical response functions are stable with amplitudes of ∼1.0–3.0 × 10−10 m per strain. Finally, the phase response is linear but not flat or zero. Our experiment demonstrates that there is potential for surface deployed DAS in planetary landscapes.

AbstractSatellite‐derived global digital elevation models (DEMs) are essential for providing the topographic information needed in a wide range of hydrological applications. However, their use is limited by spatial resolution and vertical bias due to sensor limitations in observing bare terrain. Significant efforts have been made to improve the resolution of global DEMs (e.g., TanDEM‐X) and create bare‐earth DEMs (e.g., FABDEM, MERIT, CEDTM). We evaluated the vertical accuracy of bare‐earth and global DEMs in Central European mountains and submontane regions, and assessed how DEM resolution, vegetation offset removal, land cover, and terrain slope affect stream network delineation. Using lidar‐derived DTM and national stream networks as references, we found that: (a) bare‐earth DEMs outperform global DEMs across all land cover types. RMSEs increased with increasing slope for all DEMs in non‐forest areas. In forests, however, the negative effect of the slope was outweighed by the vegetation offset even for bare‐earth DTMs; (b) the accuracy of derived stream networks was affected by terrain slope and land cover more than by the vertical accuracy of DEMs. Stream network delineation performed poorly in non‐forest areas and relatively well in forests. Increasing slope improved the streams delineation performance; (c) using DEMs with higher resolution (e.g., 12 m TanDEM‐X) improved stream network delineation, but increasing resolution also increased the need for effective vegetation bias removal. Our results indicate that vertical accuracy alone does not reflect how well DEMs perform in stream network delineation. This underscores the need to include stream network performance in DEM quality rankings.

Abstract
Human milk contains extracellular vesicles (EVs) that carry bioactive molecules such as microRNA, to the newborn intestine. The downstream effects of EV cargo on signaling and immune modulation may shield neonates against inflammatory diseases, including necrotizing enterocolitis. Premature infants are especially at risk, while human milk-feeding may offer protection. The effect of gestational-age specific term and preterm EVs from transitional human milk was characterized on human intestinal epithelial cells (HIECs and Caco-2), primary macrophages, and THP-1 monocytes. We hypothesized that term and preterm EVs differentially influence immune-related cytokines and cell death. We found that preterm EVs were enriched in CD14 surface marker, while both term and preterm EVs increased epidermal growth factor secretion. Following inflammatory stimuli, only term EVs inhibited secretion of IL-6 in HIECs, and reduced expression of pro-inflammatory cytokine IL-1β in macrophages. Term and preterm EVs inhibited secretion of IL-1β and reduced inflammasome related cell death. We proposed that human milk EVs regulate immune-related signaling via their conserved microRNA cargo, which could promote tolerance and a homeostatic immune response. These findings provide basis for further studies into potential therapeutic supplementation with EVs in vulnerable newborn populations by considering functional, gestational age-specific effects.

Impact

This study reveals distinct functional differences between term and preterm transitional human milk extracellular vesicles (EVs) highlighting the importance of gestational age in their bioactivity.

Term EVs uniquely inhibited IL-6 secretion, IL-1β expression, and apoptosis following inflammatory stimuli.

Both term and preterm human milk EVs reduced IL-1β secretion and inflammasome-induced cell death.

Conserved human milk extracellular vesicle microRNA cargo could be a mediator of the anti-inflammatory effects, particularly targeting cytokine production, the inflammasome, and programmed cell death.

These findings underscore the importance of considering gestational age in future research exploring the therapeutic potential of human milk extracellular vesicles to prevent or treat intestinal inflammatory diseases in neonates.

AbstractThe CorA/Mrs2 family of pentameric proteins are cardinal for the influx of Mg2+ across cellular membranes, importing the cation to mitochondria in eukaryotes. Yet, the conducting and regulation mechanisms of permeation remain elusive, particularly for the eukaryotic Mrs2 members. Here, we report closed and open Mrs2 cryo-electron microscopy structures, accompanied by functional characterization. Mg2+ flux is permitted by a narrow pore, gated by methionine and arginine residues in the closed state. Transition between the conformations is orchestrated by two pairs of conserved sensor-serving Mg2+-binding sites in the mitochondrial matrix lumen, located in between monomers. At lower levels of Mg2+, these ions are stripped, permitting an alternative, symmetrical shape, maintained by the RDLR motif that replaces one of the sensor site pairs in the open conformation. Thus, our findings collectively establish the molecular basis for selective Mg2+ influx of Mrs2 and an auto-ligand-gating regulation mechanism.

Abstract
Brain development requires the coordinated growth of structures and cues that are essential for forming neural circuits and cognitive functions. The corpus callosum, the largest interhemispheric connection, is formed by the axons of callosal projection neurons through a series of tightly regulated cellular events, including neuronal specification, migration, axon extension and branching. Defects in any of those steps can lead to a range of disorders known as syndromic corpus callosum dysgenesis (CCD). We report five unrelated families carrying bi-allelic variants in WDR47 presenting with CCD together with other neuroanatomical phenotypes such as microcephaly and enlarged ventricles. Using in vitro and in vivo mouse models and complementation assays, we show that WDR47 is required for survival of callosal neurons by contributing to the maintenance of mitochondrial and microtubule homeostasis. We further propose that severity of the CCD phenotype is determined by the degree of the loss of function caused by the human variants. Taken together, we identify WDR47 as a causative gene of a new neurodevelopmental syndrome characterized by corpus callosum abnormalities and other neuroanatomical malformations.
Driving range estimation for electric bus based on atomic orbital search and back propagation neural network
Authors: Ke Hanchen , Bi Jun , Wang Yongxing , Zhang Yu 
Published: November 2024

AbstractAs urbanization and transportation demands continue to increase, electric buses play an important role in sustainable urban development thanks to their advantages of emission reduction, noise and pollution reduction. However, electric buses still face some challenges, in which, range anxiety is one of the main factors limiting its popularization. To solve this problem, an accurate estimation method for the driving range of electric buses based on atomic orbital search (AOS) algorithm and back propagation neural network (BPNN) was used, in which a long‐term bus operation dataset under different driving conditions is utilized to train BPNN, and then weight and bias are taken as the first generation provided for AOS approach to find a more appropriate parameter combination. Simulation and experimental analysis show that the algorithm introduced in this paper has higher prediction accuracy and efficiency compared to the traditional machine learning algorithms, that compared with BPNN, AOSBP reduced MAE, RMSE and MAPE by 85.6%, 50.9% and 64.6%, respectively, which effectively relieves range anxiety, and ensures the normal operation of the electric bus fleet.
A Maia-type candidate was misclassified: V424 Cep is an eclipsing β Cep-type pulsator in a triple system

Published: November 2024

Context. V424 Cephei is an eclipsing binary system that has been classified as a Maia variable candidate. These objects are pulsators that apparently lie outside the theoretical instability strips.
Aims. We determine the properties of V424 Cep and identify the nature of the pulsating variable.
Methods. We analyzed photometric data obtained over the past three decades from TESS, Gaia, Hipparcos, and ground-based observations. Times of minimum light were determined, and the light curves and spectral energy distribution were analyzed. We analyzed the radial velocity curves of the double-lined system obtained from spectroscopy at the Observatorio Astronómico Nacional on the Sierra San Pedro Mártir.
Results. The two eclipses observed in the light curves yield a refined orbital period P = 4.93 d, an eccentricity e = 0.02, and an apsidal period U = 730 yr. The eclipse O–C curve is not linear. Combined with the apsidal period, this indicates the presence of a third component in the system. This conclusion was confirmed by a comparison of predicted and observed absolute fluxes. The masses of the binary pair are 8.7 M⊙ and 6.3 M⊙, their radii are 6.0 R⊙ and 3.5 R⊙, and the luminosities are log(L/L⊙) 3.80 and 3.11. The TESS light curve shows oscillations with a dominant period of 0.17 d. They are coherent throughout the orbital cycles with a stable amplitude, except during the (partial) eclipse of the primary star. This indicates that this is the pulsator. Its temperature is 21 000 K. The third-light component contributes no more than 15% to the total light of the system in the TESS wavelength band and 20% in the K band.
Conclusions. V424 Cep is not a Maia variable, but rather a β Cep star. This result highlights the importance of combining photometric light-curve solutions with absolute flux models and spectroscopic observations.
Den selection and movement patterns in a tropical savanna population of the northern quoll (Dasyurus hallucatus)
Authors: Trewella Gavin J. , Cremona Teigan , Murphy Brett P. 
Published: November 2024

Context Small mammals are undergoing significant declines across the tropical savannas of northern Australia despite a lack of widespread land clearing. The causes of these declines remain unresolved, but a growing body of evidence suggests that the structural simplification of savannas, namely the degradation of under- and overstorey vegetation by frequent fires and high densities of exotic megaherbivores, is likely to be a significant contributing factor. Aim We sought to investigate how declining mammals use critical denning resources in high-biomass mesic savannas to help explain drivers of mammal decline in more open and less mesic areas and inform management priorities. Methods We fitted VHF/GPS collars to nine northern quolls (Dasyurus hallucatus), an Endangered scansorial predatory mammal, from a remnant population located on bauxite plateaus on Cape York Peninsula, Australia, to monitor their nocturnal movement patterns and den use over 1 month. Key results During this period, northern quolls exclusively denned in trees (either standing hollow trees or fallen logs). The most frequently used den trees tended to be larger, with pronounced trunk leans and multiple hollow entrances from 5 to 20 cm in diameter, whereas the most frequently used den logs tended to be longer and had more hollow entrances from 10 to 20 cm in diameter. All home ranges were confined to the high-biomass savanna habitat found on the bauxite plateaus, with males having a mean home range almost double the size of the mean female home range. Conclusions The reliance of this population of northern quolls on large hollow-bearing trees for shelter may explain the regional contraction of the northern quoll to high-biomass mesic savannas with an abundance of large trees. Implications These high-biomass savanna habitats, such as the bauxite plateaus found on the Cape York Peninsula, are likely to be critical for the persistence of the northern quoll, and should be appropriately protected, through management of fire and avoidance of clearing and logging.
Emergent cosmological expansion in scalar–tensor theories of gravity
Authors: Briddon Chad , Clifton Timothy , Fleury Pierre 
Published: November 2024

Abstract
We consider the emergence of large-scale cosmological expansion in scalar–tensor theories of gravity. This is achieved by modelling sub-horizon regions of space-time as weak-field expansions around Minkowski space, and then subsequently joining many such regions together to create a statistically homogeneous and isotropic cosmology. We find that when the scalar field can be treated perturbatively, the cosmological behaviour that emerges is well modelled by the Friedmann solutions of the theory. When non-perturbative screening mechanisms occur this result no longer holds, and in the case of scalar fields subject to the chameleon mechanism we find significant deviations from the expected Friedmann behaviour. In particular, the screened mass no longer contributes to the Klein–Gordon equation, suppressing deviations from general relativistic behaviour.
Can ChatGPT pass a physics degree? Making a case for reformation of assessment of undergraduate degrees

Published: November 2024

Abstract
The emergence of conversational natural language processing models presents a significant challenge for Higher Education. In this work, we use the entirety of a UK Physics undergraduate (BSc with Honours) degree including all examinations and coursework to test if ChatGPT (GPT-4) can pass a degree. We adopt a ‘maximal cheating’ approach wherein we permit ourselves to modify questions for clarity, split question up into smaller sub-components, expand on answers given—especially for long form written responses, obtaining references, and use of advanced coaching, plug-ins and custom instructions to optimize outputs. In general, there are only certain parts of the degree in question where GPT-4 fails. Explicitly these include compulsory laboratory elements, and the final project which is assessed by a viva. If these were no issue, then GPT-4 would pass with a grade of an upper second class overall. In general, coding tasks are performed exceptionally well, along with simple single-step solution problems. Multiple step problems and longer prose are generally poorer along with interdisciplinary problems. We strongly suggest that there is now a necessity to urgently re-think and revise assessment practice in physics—and other disciplines—due to the existence of AI such as GPT-4. We recommend close scrutiny of assessment tasks: only invigilated in-person examinations, vivas, laboratory skills testing (or ‘performances’ in other disciplines), and presentations are not vulnerable to GPT-4, and urge consideration of how AI can be embedded within the disciplinary context.
