Fate, Desire, and Shame: Janda in Indonesian Pop Culture
Authors: Winarnita Monika Swasti , Mahy Petra , Herriman Nicholas 
Published: February 2024

AbstractResearch on images of femininityin Indonesia has largely focused on either the image of femininity produced by the state or, relatively, high-brow cultural forms of femininity. However, popular culture produces images of females that often stand in contrast to such symbolism. This article contends that thejanda, the divorcee or widow, one of the foremost images of femininity in popular music, drama, and literature, has been, for the most part, overlooked. Seen as sexually available and lascivious, thejandarepresents the “fallen woman”; an object of both fascination and pity. This article analyses thejandaimage as one of the foremost symbols in Indonesian popular culture. It is argued that thejandaimage must be analysed in relation to maiden and mother images. Furthermore, culturally specific ideas of desire, fate, and shame contextualise thejandaimage. As will become apparent, Indonesian popular culture is patriarchal, and a heterosexual male perspective frames much of the symbolism. This means that actual women live with the very real stigma of being a divorcee or a widowin Indonesia. In this study, we focus on thejandaimage and include discussion of how its representation has evolved to include a cosmopolitan ideal.
Sexuality, Shame and Subversions in Indonesian Migrant Women’s Fiction
Authors: Piocos III Carlos M. 
Published: February 2024

AbstractThis contribution examines malu (shame) as an effect of Indonesian women’s migration, illustrating how gendered moral discourses shape the problematic politics of labour migration in the country. It argues that shame not only reinforces several problematic gender and moral discourses imposed on Indonesian migrant women but also heightens their precarious role and place in their home and host countries.This essay probes into the possibilities opened by Indonesian migrant domestic workers themselves as they write, publish and circulate their own stories in Hong Kong, Singapore and Taiwan as part of the emerging cultural production of Sastra Buruh Migran Indonesia, Indonesian Migrant Workers’ Literature. It makes an innovative contribution to this collection by analysing how, in five short fiction anthologies of Indonesian migrant domestic workersin Hong Kong, Singapore and Taiwan, instances of shame and shaming matter in the representation of their daily lives and how they narrate their encounters and practices of queer sexual identities and interracial intimacies in transnational spaces. Through migrant women’s understanding of what counts as malu, I argue that their stories present a more complex negotiation of their precariousness, as they exhibit instances of agencyand mobility that go beyond traditional gender discourses upheld back home.

Tilted Dirac superconductor at quantum criticality: restoration of Lorentz symmetry
Authors: Reiser Pablo , Juričić Vladimir 
Published: February 2024

Abstract
Lorentz symmetry appears as a quite robust feature of the strongly interacting Dirac materials even though the lattice interactions break such a symmetry. We here demonstrate that the Lorentz symmetry is restored at the quantum-critical point (QCP) separating the tilted Dirac semimetal, breaking this symmetry already at the noninteracting level, from a gapped s-wave superconducting instability. To this end, we employ a one-loop ϵ = (3 − D)-expansion close to the D = 3 upper critical dimension of the corresponding Gross-Neveu-Yukawa field theory. In particular, we show that the tilt parameter is irrelevant and ultimately vanishes at the QCP separating the two phases. In fact, as we argue here, such a Lorentz symmetry restoration may be generic for the strongly interacting tilted Dirac semimetals, irrespective of whether they feature mirror-symmetric or mirror-asymmetric tilting, and is also insensitive to whether the instability represents an insulator or a gapped superconductor. The proposed scenario can be tested in the quantum Monte Carlo simulations of the interacting tilted Dirac fermion lattice models.
Fermions at finite density in the path integral approach
Authors: Podo Alessandro , Santoni Luca 
Published: February 2024

Abstract
We study relativistic fermionic systems in 3 + 1 spacetime dimensions at finite chemical potential and zero temperature, from a path-integral point of view. We show how to properly account for the iε term that projects on the finite density ground state, and compute the path integral analytically for free fermions in homogeneous external backgrounds, using complex analysis techniques. As an application, we show that the U(1) symmetry is always linearly realized for free fermions at finite charge density, differently from scalars. We study various aspects of finite density QED in a homogeneous magnetic background. We compute the free energy density, non-perturbatively in the electromagnetic coupling and the external magnetic field, obtaining the finite density generalization of classic results of Euler-Heisenberg and Schwinger. We also obtain analytically the magnetic susceptibility of a relativistic Fermi gas at finite density, reproducing the de Haas-van Alphen effect. Finally, we consider a (generalized) Gross-Neveu model for N interacting fermions at finite density. We compute its non-perturbative effective potential in the large-N limit, and discuss the fate of the U(1) vector and $$ {\mathbb{Z}}_2^A $$

Scalar quasi-normal modes of accelerating Kerr-Newman-AdS black holes
Authors: Amado Julián Barragán , Gwak Bogeun 
Published: February 2024

Abstract
We study linear scalar perturbations of slowly accelerating Kerr-Newman-anti-de Sitter black holes using the method of isomonodromic deformations. The conformally coupled Klein-Gordon equation separates into two second-order ordinary differential equations with five singularities. Nevertheless, the angular equation can be transformed into a Heun equation, for which we provide an asymptotic expansion for the angular eigenvalues in the small acceleration and rotation limit. In the radial case, we recast the boundary value problem in terms of a set of initial conditions for the isomonodromic tau function of Fuchsian systems with five regular singular points. For the sake of illustration, we compute the quasi-normal modes frequencies.
Spontaneous collapse models lead to the emergence of classicality of the Universe
Authors: Gaona-Reyes José Luis , Menéndez-Pidal Lucía , Faizal Mir , Carlesso Matteo 
Published: February 2024

Abstract
Assuming that Quantum Mechanics is universal and that it can be applied over all scales, then the Universe is allowed to be in a quantum superposition of states, where each of them can correspond to a different space-time geometry. How can one then describe the emergence of the classical, well-defined geometry that we observe? Considering that the decoherence-driven quantum-to-classical transition relies on external physical entities, this process cannot account for the emergence of the classical behaviour of the Universe. Here, we show how models of spontaneous collapse of the wavefunction can offer a viable mechanism for explaining such an emergence. We apply it to a simple General Relativity dynamical model for gravity and a perfect fluid. We show that, by starting from a general quantum superposition of different geometries, the collapse dynamics leads to a single geometry, thus providing a possible mechanism for the quantum-to-classical transition of the Universe. Similarly, when applying our dynamics to the physically-equivalent Parametrised Unimodular gravity model, we obtain a collapse on the basis of the cosmological constant, where eventually one precise value is selected, thus providing also a viable explanation for the cosmological constant problem. Our formalism can be easily applied to other quantum cosmological models where we can choose a well-defined clock variable.
Non-linear electrodynamics from massive gravity
Authors: Flöss Thomas , Roest Diederik , Westerdijk Tom 
Published: February 2024

Abstract
As a counterpart to the four-fermion interaction, which describes massive vector exchange at low energies, we investigate the low energy effective action of photons under exchange of a massive graviton. We show how integrating out a massive graviton leads to the most general duality-invariant vector interactions in 4D or, vice versa, how any such interactions have a natural interpretation within massive gravity. Moreover, we demonstrate how the special case of Born-Infeld theory arises from arguably the simplest graviton potential within ghost-free dRGT massive gravity.
Connection Between Weighted Tail, Orlicz, Grand Lorentz And Grand Lebesgue Norms

Published: February 2024

AbstractWe prove that the norm of functions in a suitable Grand Lorentz space built on a measure space, equipped with sigma finite diffuse measure, coincides with the norm in a suitable exponential Grand Lebesgue Space space as well as coincides with the so-called exponential tail norm, which may be quite described as norm in a suitable Banach rearrangement invariant space. We also exhibit comparisons with exponential Orlicz norms.
On Distribution of Rice–Middleton Model

Published: February 2024

AbstractThe probability density function in Rice–Middleton model, which describes the behavior of the single sinusoidal random signal combined with Gaussian noise is expressed in three mutually independent ways: firstly, with the aid of an integral representation of the modified Bessel function of the first kind of integer order; secondly, by a hyperbolic cosine differential operator and thirdly, applying the Grünwald–Letnikov fractional derivative. The cumulative distribution functions are also described in all these cases, and also using the Nuttall Q–function. An associated, seemingly new, probability distribution is introduced which cumulative distribution function and the raw moments of general real order are obtained whilst the characteristic function’s power series form is inferred. The exposition ends with a discussion in which by–product summations are given for the considered Neumann series of the second type built by modified Bessel functions of the second kind having integer order.
2-Styrylchromones as inhibitors of α-amylase and α-glucosidase enzymes for the management of type 2 diabetes mellitus

Published: February 2024

Abstractα-amylase and α-glucosidase are key enzymes implicated in carbohydrate digestion and their inhibition has been suggested as a powerful approach for regulating blood glucose levels. The present work describes for the first time their inhibition by a group of twelve hydroxylated 2-styrylchromones (2-SC). Our findings revealed that 2-SC display strong systematic inhibition of α-glucosidase rather than α-amylase activity. The number and position of the hydroxy groups in the chromone moiety further modulate the inhibitory profile of the studied compounds, and the derivatives bearing one catechol unit are efficient inhibitors of both enzymes. Enzyme kinetic studies indicate that all active compounds act as competitive inhibitors of α-amylase while most of them behave as non-competitive inhibitors of α-glucosidase. The results are promising and pave the way to further deciphering the potential of this class of compounds as a suitable alternative for the management of type 2 diabetes and its complications.

Published: February 2024

AbstractThere is a significant co-occurrence of opioid use disorder (OUD) and post-traumatic stress disorder (PTSD) in clinical populations. However, the neurobiological mechanisms linking chronic opioid use, withdrawal, and the development of PTSD are poorly understood. Our previous research has shown that proinflammatory cytokines, expressed primarily by astrocytes in the dorsal hippocampus (DH), play a role in the development of heroin withdrawal-enhanced fear learning (HW-EFL), an animal model of PTSD-OUD comorbidity. Given the role of astrocytes in memory, fear learning, and opioid use, our experiments aimed to investigate their involvement in HW-EFL. Experiment 1 examined the effect of withdrawal from chronic heroin administration on GFAP surface area and volume, and identified increased surface area and volume of GFAP immunoreactivity in the dentate gyrus (DG) following 24-hour heroin withdrawal. Experiment 2 examined astrocyte morphology and synaptic interactions at the 24-hour withdrawal timepoint using an astroglial membrane-bound GFP (AAV5-GfaABC1D-lck-GFP). Although we did not detect significant changes in surface area and volume of GfaABC1D-Lck-GFP labelled astrocytes, we did observe a significant increase in the colocalization of astrocyte membranes with PSD-95 (postsynaptic density protein 95) in the DG. Experiment 3 tested if stimulating astroglial Gi signaling in the DH alters HW-EFL, and our results demonstrate this manipulation attenuates HW-EFL. Collectively, these findings contribute to our current understanding of the effects of heroin withdrawal on astrocytes and support the involvement of astrocytes in the comorbid relationship between opioid use and anxiety disorders.

AbstractIt is well known that information on stimulus orientation plays an important role in sensory processing. However, the neural mechanisms underlying somatosensory orientation perception are poorly understood. Adaptation has been widely used as a tool for examining sensitivity to specific features of sensory stimuli. Using the adaptation paradigm, we measured event-related potentials (ERPs) in response to tactile orientation stimuli presented pseudo-randomly to the right-hand palm in trials with all the same or different orientations. Twenty participants were asked to count the tactile orientation stimuli. The results showed that the adaptation-related N60 component was observed around contralateral central-parietal areas, possibly indicating orientation processing in the somatosensory regions. Conversely, the adaptation-related N120 component was identified bilaterally across hemispheres, suggesting the involvement of the frontoparietal circuitry in further tactile orientation processing. P300 component was found across the whole brain in all conditions and was associated with task demands, such as attention and stimulus counting. These findings help provide an understanding of the mechanisms of tactile orientation processing in the human brain.

Published: February 2024

AbstractMost animal behaviors show large within- and among-individual variation, and this includes competitive male behaviors. With male fighting for example, aggressiveness often correlates with dominance, and contest duration varies with age. However, few studies have directly quantified how mean aggressiveness and contest duration, the variation among individuals in both traits, and the relationship among them, vary with age. Here we address these gaps and examine the effect of male age and genotype on two key aspects of male fighting behavior - aggressiveness (here measured as latency to fight) and contest duration - and the relationship between them. We do this using isogenic lines of the broad-horned flour beetle Gnatocerus cornutus. We observed fighting behavior of paired males of similar body size and age. Using uni- and multivariate mixed models, we show that although there was a significant difference between younger and older males in contest duration, mean aggressiveness was not affected by male age. However, the variation in aggression and fight duration varied with age, being greater in younger and older males respectively. Additionally, although there was a positive correlation between aggressiveness and contest duration in younger males, this relationship was not found in older males. Finally, the only significant genetic effect was for aggression in younger males. Our study shows that age differentially shapes key components of male fighting behavior as well as the relationship among them, highlighting the dynamic nature and context-dependence of fighting.

Abstract
Key message
High-frequency clonal seeds and near-normal fertility were obtained by engineering synthetic apomixis in hybrid rice.

Abstract
The one-line strategy, with the advantage of unnecessary seed production, is the final stage for the hybrid rice development and can be achieved through the fixation of heterosis via artificially inducing apomixis. Recently, synthetic apomixis has been generated in rice by combining MiMe (Mitosis instead of Meiosis) with either the ectopic expression of BABY BOOM (BBM1 or BBM4) or mutation of MATRILINEAL (MTL), resulting in over 95.00% of clonal seeds. However, the frequency of clonal seeds was only 29.20% when AtDD45 promoter was used to drive BBM1. In addition, achieving both a high frequency of clonal seeds and near-normal fertility simultaneously had been elusive in earlier strategies. In this study, using AtDD45 promoter to drive BBM1 expression in combination with the MiMe mutant resulted in the apomixis frequency as high as 98.70%. Even more, employing fusion promoters (AtMYB98_AtDD1_OsECA1-like1) to drive WUS expression in combination with pAtDD45:BBM1 and MiMe could produce clonal seeds at rates of up to 98.21%, the highest seed setting rate reached to 83.67%. Multiple-embryos were observed in clonal lines at a frequency ranging from 3.37% to 60.99%. Transmission of the high frequency of apomixis through skipped generations (atavism) was identified in two clonal lines, even though it remained stable in the majority of clonal lines. These findings significantly advance the pursuit of fixed heterosis in rice through synthetic apomixis, edging closer to its agricultural application.

Published: February 2024

AbstractFunction-based studies have opened a new chapter in our understanding of coral reefs. Unfortunately, we are opening this chapter as the world’s reefs rapidly transform. In this context, one of the most important roles of function-based studies is to inform coral reef conservation. At this critical juncture, we have a chance to reflect on where we have come from, and where we are going, in coral reef functional ecology, with specific consideration of what this means for our approaches to conserving reefs. As focal examples, we examine the role of corals on reefs, and the practice of culling crown-of-thorns starfish, from a functional perspective. We also consider how the papers in this special issue build on our current understanding. Ultimately, we highlight how robust scientific investigation, based on an understanding of ecosystem functions, will be key in helping us navigate reefs through the current coral reef crisis.
The Impact of Sentiment Scores Extracted from Product Descriptions on Customer Purchase Intention
Authors: Sun Yi , Sekiguchi Kaira , Ohsawa Yukio 
Published: February 2024

AbstractThis study investigates whether and how the textual content of product descriptions, especially the sentiment element, influences buyers’ purchase intentions. Using year-round digital transaction data from Mercari, a leading e-Commerce platform in Japan, we examine the interplay of hard and soft information signals exchanged between sellers and buyers. The study addresses two crucial questions: (1) Do the descriptions that sellers provide on product sales pages impact the buyer’s intent to purchase? and (2) In what way does the description influence the buyer’s purchase intention? Quantitative analysis is used to understand the relationship between product descriptions, sentiment elements, and purchase intentions. The results show that sentiment factors in product descriptions can serve as high-quality “signals” that can help buyers make informed purchasing decisions and reduce information asymmetry between buyers and sellers. This research contributes to understanding decision-making in online markets, particularly the role of soft information and sentiment analysis.

AbstractThe15N gas flux (15NGF) method allows for direct in situ quantification of dinitrogen (N2) emissions from soils, but a successful cross-comparison with another method is missing. The objectives of this study were to quantify N2emissions of a wheat rotation using the15NGF method, to compare these N2emissions with those obtained from a lysimeter-based15N fertilizer mass balance approach, and to contextualize N2emissions with15N enrichment of N2in soil air. For four sampling periods, fertilizer-derived N2losses (15NGF method) were similar to unaccounted fertilizer N fates as obtained from the15N mass balance approach. Total N2emissions (15NGF method) amounted to 21 ± 3 kg N ha− 1, with 13 ± 2 kg N ha− 1(7.5% of applied fertilizer N) originating from fertilizer. In comparison, the15N mass balance approach overall indicated fertilizer-derived N2emissions of 11%, equivalent to 18 ± 13 kg N ha− 1. Nitrous oxide (N2O) emissions were small (0.15 ± 0.01 kg N ha− 1or 0.1% of fertilizer N), resulting in a large mean N2:(N2O + N2) ratio of 0.94 ± 0.06. Due to the applied drip fertigation, ammonia emissions accounted for < 1% of fertilizer-N, while N leaching was negligible. The temporal variability of N2emissions was well explained by the δ15N2in soil air down to 50 cm depth. We conclude the15NGF method provides realistic estimates of field N2emissions and should be more widely used to better understand soil N2losses. Moreover, combining soil air δ15N2measurements with diffusion modeling might be an alternative approach for constraining soil N2emissions.
