Published: November 2023

Abstract
Soil environments are inhabited by microorganisms adapted to its diversified microhabitats. The metabolic activity of individual strains/populations reflects resources available at a particular spot, quality of which may not comply with broad soil characteristics. To explore the potential of individual strains to adapt to particular micro-niches of carbon sources, a set of 331 Actinomycetia strains were collected at ten sites differing in vegetation, soil pH, organic matter content and quality. The strains were isolated on the same complex medium with neutral pH and their metabolites analyzed by UHPLC and LC-MS/MS in spent cultivation medium (metabolic profiles). For all strains, their metabolic profiles correlated with soil pH and organic matter content of the original sites. In comparison, strains phylogeny based on either 16S rRNA or the beta-subunit of DNA-dependent RNA polymerase (rpoB) genes was partially correlated with soil organic matter content but not soil pH at the sites. Antimicrobial activities of strains against Kocuria rhizophila, Escherichia coli, and Saccharomyces cerevisiae were both site- and phylogeny-dependent. The precise adaptation of metabolic profiles to overall sites characteristics was further supported by the production of locally specific bioactive metabolites and suggested that carbon resources represent a significant selection pressure connected to specific antibiotic activities.
Materializing France in exile: Henri, duc d’Aumale, the Orléans family and the transnational politics of collecting c. 1848–80
Authors: Stammers Tom 
Published: November 2023

Abstract
Between the 1848 Revolution and the Franco–Prussian War, the fallen Orléans dynasty lived in the western suburbs of London. Deprived of the throne, Louis-Philippe and his sons struggled to uphold their dignity and credentials as a ruling house. In this time of limbo, cultural pursuits—whether art collecting, exhibitions, literature—were a crucial means of integration into the elite tiers of British society. Material culture remained a central means by which the family affirmed and preserved their dual patriotic and dynastic credentials. Focusing on the collecting activities of the duc d’Aumale in London, this article explores how the experiences and opportunities of British exile profoundly shaped how the Orléans positioned themselves as custodians of French history and national identity. An act of cultural resistance against French governments that had banished and ‘denationalized’ them, art collecting offers a valuable window onto the family’s patriotic self-image and evolving political ambitions.
Russia and the liberal order: from contestation to antagonism
Authors: Morozov Viacheslav 
Published: November 2023

Abstract
Russia's large-scale war against Ukraine is rightfully viewed as a major violation of the fundamental norms of international society. It creates a problem for the literature on the liberal international order, which used to treat Russia as engaging in contestation—a legitimate practice which, according to some accounts, constitutes an essential aspect of any order. This article aims to develop a conceptual frame for the radical rupture resulting from the war by describing it as an expansion of antagonism. In the post-structuralist theory employed here, antagonism is always present at the margins of any order as a daily experience of failure, of the impossibility of total ordering. Russia's war started from the rhetorical negation of Ukraine's existence as a sovereign nation, but expanded into an antagonism that eventually threatens to ‘cancel’ Russia itself. To explore this case conceptually and empirically, I approach international order as a set of performative practices unfolding within a hegemonic structure. Russia is not alone in perceiving the liberal hegemony as unjust, but the expansion of antagonism on such a scale is rather unique. It can be damaging to democracy worldwide unless it is mobilized for the construction of broader anti-war coalitions.
The protection against unfair competition and passing off in ASEAN Member States: a review and commentary
Authors: Calboli Irene 
Published: November 2023

Abstract
This article offers a brief review of the protection against unfair competition in the Member States of the Association of South-East Asian Nations (ASEAN). More specifically, it highlights ASEAN’s different legal systems and how ASEAN Members, respectively, implement Article 10bis of the Paris Convention under national unfair competition or laws against passing off based on their respective legal system—Civil Law, Common Law and hybrid systems. Ultimately, this article notes that, despite these different legal systems, ASEAN Members share close similarities in their national implementation of Article 10bis of the Paris Convention. The article concludes that these similarities are not surprising considering the shared history of several ASEAN Members and the fact that all these countries (with the exception of Myanmar) are signatories to the major international IP agreements.

Abstract
Iron (Fe), manganese (Mn), copper (Cu), and zinc (Zn) are essential micronutrients that are necessary for plant growth and development, but can be toxic at supra-optimal levels. Plants have evolved a complex homeostasis network that includes uptake, transport, and storage of these metals. It was shown that the transcription factor (TF) complex OsbHLH156–OsIRO2 is activated under Fe deficient conditions and acts as a central regulator on Strategy II Fe acquisition. In this study, the role of the TF complex on Mn, Cu, and Zn uptake was evaluated. While Fe deficiency led to significant increases in shoot Mn, Cu, and Zn concentrations, the increases of these divalent metal concentrations were significantly suppressed in osbhlh156 and osiro2 mutants, suggesting that the TF complex plays roles on Mn, Cu, and Zn uptake and transport. An RNA-sequencing assay showed that the genes associated with Mn, Cu, and Zn uptake and transport were significantly suppressed in the osbhlh156 and osiro2 mutants. Transcriptional activation assays demonstrated that the TF complex could directly bind to the promoters of OsIRT1, OsYSL15, OsNRAMP6, OsHMA2, OsCOPT1/7, and OsZIP5/9/10, and activate their expression. In addition, the TF complex is required to activate the expression of nicotianamine (NA) and 2'-deoxymugineic acid (DMA) synthesis genes, which in turn facilitate the uptake and transport of Mn, Cu, and Zn. Furthermore, OsbHLH156 and OsIRO2 promote Cu accumulation to partially restore the Fe-deficiency symptoms. Taken together, OsbHLH156 and OsIRO2 TF function as core regulators not only in Fe homeostasis, but also in Mn, Cu, and Zn accumulation.
Deubiquitination of SARM1 by USP13 regulates SARM1 activation and axon degeneration

Published: November 2023

Abstract
Sterile alpha and Toll/interleukin 1 receptor motif-containing protein 1 (SARM1) is regarded as a key protein and a central executor of the self-destruction of injured axons. To identify novel molecular players and understand the mechanisms regulating SARM1 function, we investigated the interactome of SARM1 by proximity labeling and proteomic profiling. Among the SARM1-associated proteins, we uncovered that overexpression (OE) of ubiquitin-specific peptidase 13 (USP13) delayed injury-induced axon degeneration. OE of an enzyme-dead USP13 failed to protect injured axons, indicating that the deubiquitinase activity of USP13 was required for its axonal protective effect. Further investigation revealed that USP13 deubiquitinated SARM1, which increased the inhibitory interaction between the N-terminal armadillo repeat motif (ARM) and C-terminal Toll/interleukin-1 receptor (TIR) domains of the SARM1 protein, thereby suppressing SARM1 activation in axon injury. Collectively, these findings suggest that increase of USP13 activity enhances the self-inhibition of SARM1, which may provide a strategy to mitigate axon degeneration in injury and disease.
Methanol isotopologues as a probe for spatial and temporal variations of the electron-to-proton mass ratio
Authors: Vorotyntseva J S , Kozlov M G , Levshakov S A 
Published: November 2023

ABSTRACT
We present results on numerical calculations of the sensitivity coefficients, Qμ, of microwave molecular transitions in 13CH3OH and ${\rm CH_3\, ^{18}OH}$ to the hypothetical variation in the fundamental physical constant μ – the electron-to-proton mass ratio. The invariability of μ in time and space is one of the basic assumptions of the Standard Model of particle physics which can be tested at cosmological scales by means of astronomical observations in the Galaxy and external galaxies. Our calculations show that these two methanol isotopologues can be utilized for such tests since their microwave transitions from the frequency interval 1–100 GHz exhibit a large spread in Qμ values which span a range of −109 ≲ Qμ ≲ 78. We show that the thermal emission lines of 13CH3OH observed in the star-forming region NGC 6334I constrain the variability of μ at a level of 3 × 10−8 (1σ), which is in line with the most stringent upper limits obtained previously from observations of methanol (CH3OH) and other molecules in the Galaxy.
On the feasibility of primordial black hole abundance constraints using lensing parallax of GRBs
Authors: Gawade Priyanka , More Surhud , Bhalerao Varun 
Published: November 2023

ABSTRACT
Primordial black holes, which could have formed during the early Universe through overdensities in primordial density fluctuations during inflation, are potential candidates for dark matter. We explore the use of lensing parallax of gamma-ray bursts (GRBs), which results in different fluxes being observed from two different vantage points, in order to probe the abundance of primordial black holes in the unexplored window within the mass range 10−15 to 10−11 $\mathrm{ {M}_\odot}$. We derive the optical depth for the lensing of GRBs with a distribution of source properties and realistic detector sensitivities. We comment on the ability of the proposed Indian twin satellite mission Daksha in its low Earth orbit to conduct this experiment. If the two Daksha satellites observe 10 000 GRBs simultaneously and the entirety of dark matter is made up of 10−15 to 10−12 $\mathrm{ {M}_\odot}$ black holes, Daksha will detect non-zero lensing events with a probability ranging from 80 to 50 per cent at the bin edges, respectively. Non-detections will not conclusively rule out primordial black holes as dark matter in this mass range. However, we show that meaningful constraints can be obtained in such a case if the two satellites are separated by at least the Earth–Moon distance.
Star formation history of the post-collisional Cartwheel galaxy using AstroSat/UVIT FUV images
Authors: Mayya Y D , Barway Sudhanshu , Gómez-González V M A , Zaragoza-Cardiel J 
Published: November 2023

ABSTRACT
We present the results obtained by analysing the new AstroSat Ultra-Violet Imaging Telescope (UVIT) far-ultraviolet (FUV) image of the collisional-ring galaxy Cartwheel. The FUV emission is principally associated with the star-forming outer ring, with no ultraviolet detection from the nucleus and inner ring. A few sources are detected in the region between the inner and the outer rings, all of which lie along the spokes. The FUV fluxes from the detected sources are combined with aperture-matched multiband photometric data from archival images to explore the post-collision star formation history of the Cartwheel. The data were corrected for extinction using AV derived from the Balmer decrement ratios and commonly used extinction curves. We find that the ring regions contain stellar populations of a wide range of ages, with the bulk of the FUV emission coming from non-ionizing stars, formed over the last 20–150 Myr, that are ∼25 times more massive than the ionizing populations. On the other hand, regions belonging to the spokes have negligible current star formation, with the age of the dominant older population systematically increasing as its distance from the outer ring increases. The presence of populations of a wide range of ages in the ring suggests that the stars formed in the wave in the past were dragged along it to the current position of the ring. We derive an average steady star formation rate, SFR = 5 ${\rm M}_{\odot }\, {\rm yr}^{-1}$, over the past 150 Myr, with an increase to ∼18 ${\rm M}_{\odot }\, {\rm yr}^{-1}$ in the recent 10 Myr.
Massive star formation in the hub–filament system of RCW 117
Authors: Seshadri Arun , Vig S , Ghosh S K , Ojha D K 
Published: November 2023

ABSTRACT
We present a multiwavelength investigation of the hub–filament system RCW 117 (IRAS 17059-4132), which shows intricate filamentary features in the far-infrared, mapped using Herschel images. We obtain the column density and dust temperature maps for the region using the Herschel images and identify 88 cores and 12 filaments from the column density map of the region (18 arcmin × 18 arcmin). We employ the ThrUMMS 13CO (J = 1–0) data for probing the kinematics in RCW 117, and find velocity gradients (∼0.3–1 km s−1 pc−1) with hints of matter inflow along the filamentary structures. Ionized gas emission from the associated H ii region is examined using the Giant Metrewave Radio Telescope (GMRT) at 610 and 1280 MHz and is found to be of extent 5 × 3 pc2 with intensity being brightest towards the hub. We estimate the peak electron density towards the hub to be ∼750 cm−3. Thirty-four Class 0/I young stellar objects (YSOs) have been identified in the region using the Spitzer GLIMPSE colour–colour diagram, with many lying along the filamentary structures. Based on the (i) presence of filamentary structures, (ii) distribution of cores across the region, with ∼39 per cent found along the filamentary structures, (iii) massive star formation tracers in the hub, and (iv) the kinematics, we believe that global hierarchical collapse can plausibly explain the observed features in RCW 117.
VLA monitoring of LS V +44 17 reveals scatter in the X-ray–radio correlation of Be/X-ray binaries

ABSTRACT
LS V +44 17 is a persistent Be/X-ray binary (BeXRB) that displayed a bright, double-peaked period of X-ray activity in late 2022/early 2023. We present a radio monitoring campaign of this outburst using the Very Large Array. Radio emission was detected, but only during the second, X-ray brightest, peak, where the radio emission followed the rise and decay of the X-ray outburst. LS V +44 17 is therefore the third neutron star BeXRB with a radio counterpart. Similar to the other two systems (Swift J0243.6+6124 and 1A 0535+262), its X-ray and radio luminosity are correlated: we measure a power-law slope $\beta = 1.25^{+0.64}_{-0.30}$ and a radio luminosity of LR = (1.6 ± 0.2) × 1026 erg s−1 at a 0.5–10 keV X-ray luminosity of 2 × 1036 erg s−1 (i.e. $\sim 1~{{\ \rm per\ cent}}$LEdd). This correlation index is slightly steeper than measured for the other two sources, while its radio luminosity is higher. We discuss the origin of the radio emission, specifically in the context of jet launching. The enhanced radio brightness compared to the other two BeXRBs is the first evidence of scatter in the giant BeXRB outburst X-ray–radio correlation, similar to the scatter observed in subclasses of low-mass X-ray binaries. While a universal explanation for such scatter is not known, we explore several options: we conclude that the three sources do not follow proposed scalings between jet power and neutron star spin or magnetic field, and instead briefly explore the effects that ambient stellar wind density may have on BeXRB jet luminosity.
The AGN fraction in high-redshift protocluster candidates selected by Planck and Herschel

Published: November 2023

ABSTRACT
A complete understanding of the mass assembly history of structures in the Universe requires the study of the growth of galaxies and their supermassive black holes (SMBHs) as a function of their local environment over cosmic time. In this context, it is important to quantify the effects that the early stages of galaxy cluster development have on the growth of SMBHs. We used a sample of Herschel/SPIRE sources of ∼ 228 red and compact Planck-selected protocluster (PC) candidates to estimate the active galactic nuclei (AGNs) fraction from a large sample of galaxies within these candidates. We estimate the AGN fraction by using the mid-infrared (mid-IR) photometry provided by the WISE/AllWISE data of ∼650 counterparts at high redshifts. We created an AllWISE mid-IR colour–colour selection using a clustering machine learning algorithm and two WISE colour cuts using the 3.4 $\mu$m (W1), 4.6 $\mu$m (W2), and 12 $\mu$m (W3) passbands, to classify sources as AGN. We also compare the AGN fraction in PCs with that in the field to better understand the influence of the environment on galaxy development. We found an AGN fraction of fAGN = 0.113 ± 0.03 in PC candidates and an AGN fraction of fAGN = 0.095 ± 0.013 in the field. We also selected a subsample of ‘red’ SPIRE subsample with a higher overdensity significance, obtaining fAGN = 0.186 ± 0.044, versus fAGN = 0.037 ± 0.010 of ‘non-red sources’, consistent with higher AGN fractions for denser environments. We conclude that our results point towards a higher AGN fraction in PCs, similar to other studies.

ABSTRACT
AM CVn-type systems are ultracompact, helium-accreting binary systems that are evolutionarily linked to the progenitors of thermonuclear supernovae and are expected to be strong Galactic sources of gravitational waves detectable to upcoming space-based interferometers. AM CVn binaries with orbital periods ≲20–23 min exist in a constant high state with a permanently ionized accretion disc. We present the discovery of TIC 378898110, a bright (G = 14.3 mag), nearby (309.3 ± 1.8 pc), high-state AM CVn binary discovered in TESS two-minute-cadence photometry. At optical wavelengths, this is the third-brightest AM CVn binary known. The photometry of the system shows a 23.07172(6) min periodicity, which is likely to be the ‘superhump’ period and implies an orbital period in the range 22–23 min. There is no detectable spectroscopic variability. The system underwent an unusual, year-long brightening event during which the dominant photometric period changed to a shorter period (constrained to 20.5 ± 2.0 min), which we suggest may be evidence for the onset of disc-edge eclipses. The estimated mass transfer rate, $\log (\dot{M} / \mathrm{M_\odot } \, \mathrm{yr}^{-1}) = -6.8 \pm 1.0$, is unusually high and may suggest a high-mass or thermally inflated donor. The binary is detected as an X-ray source, with a flux of $9.2 ^{+4.2}_{-1.8} \times 10^{-13}$ erg cm−2 s−1 in the 0.3–10 keV range. TIC 378898110 is the shortest-period binary system discovered with TESS, and its large predicted gravitational-wave amplitude makes it a compelling verification binary for future space-based gravitational wave detectors.
Period evolution of repeating transients in galactic nuclei
Authors: Linial Itai , Quataert Eliot 
Published: November 2023

ABSTRACT
Wide-field surveys have recently detected recurring optical and X-ray sources near galactic nuclei, with period spanning hours to years. These phenomena could result from repeated partial tidal disruptions of stars by supermassive black holes (SMBHs) or by interaction between star and SMBH-accretion discs. We study the physical processes that produce period changes in such sources, highlighting the key role of the interaction between the orbiting star and the accretion disc. We focus on ASASSN-14ko – a repeatedly flaring optical source with a mean period $P_0 = 115 \, \rm d$ and a detected period decay $\dot{P} = -2.6\times 10^{-3}$ (Payne et al. 2022). We argue that the system’s $\dot{P}$ is most compatible with true orbital decay produced by hydrodynamical drag as a star passes through the accretion disc on an inclined orbit, twice per orbit. The star is likely a sun-like star whose envelope is somewhat inflated, possibly due to tidal heating. Star–disc interaction inevitably leads to drag-induced stripping of mass from the star, which may be the dominant component in powering the observed flares. We discuss ASASSN-14ko’s possible formation history and observational tests of our interpretation of the measured $\dot{P}$. Our results imply that partial tidal disruption events manifesting as repeating nuclear transients cannot be modelled without accounting for the cumulative impact of tidal heating over many orbits. We discuss the implications of our results for other repeating transients, and predict that the recurrence time of quasi-periodic eruptions is expected to decay at a rate of the order of $|\dot{P}| \approx 10^{-6}-10^{-5}$.
Rural Identity and LGBT Public Opinion in the United States
Authors: Thompson Jack 
Published: November 2023

Abstract
Opposition to LGBT rights remains a contemporary fixture within the United States in spite of increasingly liberalizing attitudes toward LGBT individuals. In this paper, I argue that a potentially overlooked factor driving this opposition is rural identity—or an individual’s psychological attachment to a rural area. Using data from the 2020 ANES, I find that rural identity predicts less favorable estimations of LGBT individuals. Rural identifiers are also less likely to support pro-LGBT policy measures than nonrural identifiers. Nevertheless, I find the magnitude of the effects of rural identity on anti-LGBT views to be surprisingly small. It is also the case that, on average, rural identifiers exhibit net-positive estimations of LGBT individuals and are broadly supportive of LGBT rights, suggesting that elected officials enacting anti-LGBT legislation in rural areas of the United States are potentially out of step with the preferences of their electorate. These findings also have implications for what it means to hold a rural identity beyond a generalized animosity toward urban areas, and for understanding urban-rural divergences in US public opinion on issues such as LGBT rights.
