Polycyclic Aromatic Hydrocarbons in the Circumstellar Medium of Herbig Ae/Be Stars
We present a comprehensive mid-infrared spectroscopic survey of 124 Herbig Ae/Be stars using newly processed Spitzer/IRS spectra from the newly released CASSISjuice database. Based on prominent dust and molecular signatures (polycyclic aromatic hydrocarbons (PAHs), silicates, and hydrogenated amorphous carbons), we classify the stars into five groups. Our analysis reveals that 64% of the spectra show PAH emission, with detections peaking in the stellar effective temperature range 7000-11,000 K (B9-A5). Silicate features appear in 50% of the sample and likewise diminish at higher temperatures. Additionally, we find that future PAH studies can focus on Herbig Ae/Be stars with a spectral index n2?24 > ?1 and flared morphologies to maximize PAH detections. The 6.2 ?m PAH band is the most frequently observed in our sample, shifting blueward with increasing stellar temperature, and this is the largest sample yet used to test that peak shift. The weaker 6.0 ?m feature does not shift with 6.2 ?m, implying a distinct origin of C=O (carbonyl) or olefinic C=C stretching relative to C-C vibrations. We examined the 11.0/11.2 ?m PAH ratio using high-resolution Spitzer spectra for the first time in a sample of Herbig Ae/Be stars, finding a range of ionization conditions. This study provides a strong foundation for future JWST observations of intermediate-mass pre-main-sequence stars. 2025. National Astronomical Observatories, CAS and IOP Publishing Ltd.

Spontaneous symmetry breaking as a late-time trigger for interacting dark energy
Persistent tensions in the Hubble constant (H 0) and the matter clustering parameter (S 8) motivate late-time new physics that suppresses structure growth while remaining compatible with current background constraints of the ?CDM model. We study a new class of dark sector dynamics in which a scalar dark energy (DE) field, governed by a ?2-symmetric quartic potential, interacts with dark matter (DM) through Yukawa and portal couplings. When the matter density drops below a critical threshold, a cosmological spontaneous symmetry breaking (SSB) mechanism generates a time-dependent vacuum expectation value v(a) and activates an effective coupling ?(a). This produces a symmetric phase (a ? ac) identical to ?CDM at early times, and a broken phase (a > ac) in which ?(a) > 0 transfers energy from DM to DE, suppressing the linear growth of structure. We confront this framework with RSD, BAO, CC, and Pantheon+SH0ES supernova data, jointly with compressed Planck distance priors, comparing a fixed ?CDM background to a self-consistent coupled scalar evolution. The RSD-only analysis shows a pronounced shift: the dynamical background yields ?m ? 0.31 0.10 and ? 80 ? 0.59 0.01, with a higher matter density but a substantially lower growth amplitude compared to the fixed background case ?m ? 0.20 0.09 and ? 80 ? 0.75 0.05. In the full joint fit, conditioned on geometric distance information, the inferred parameters are ?m = 0.29 0.01, H 0 = 69.7 0.6 km s-1 Mpc-1, and ? 80 = 0.78 0.01. These results demonstrate that a late-time, SSB-activated interaction can efficiently dampen structure growth and potentially alleviate the S 8 tension. In growth-dominated analyses such as RSD-only constraints, the inferred value of H 0 is only weakly affected by the coupling. However, in joint analyses including strong external distance calibrations, the inferred H 0 becomes sensitive to dataset choice and to whether the background expansion is treated self-consistently. 2026 IOP Publishing Ltd and Sissa Medialab.

The Lunar Gravitational-wave Antenna: mission studies and science case
The Lunar Gravitational-wave Antenna (LGWA) is a proposed array of next-generation inertial sensors to monitor the response of the Moon to gravitational waves (GWs). Given the size of the Moon and the expected noise produced by the lunar seismic background, the LGWA would be able to observe GWs from about 1 mHz to 1 Hz. This would make the LGWA the missing link between space-borne detectors like LISA with peak sensitivities around a few millihertz and proposed future terrestrial detectors like Einstein Telescope or Cosmic Explorer. In this article, we provide a first comprehensive analysis of the LGWA science case including its multi-messenger aspects and lunar science with LGWA data. We also describe the scientific analyses of the Moon required to plan the LGWA mission. 2025 The Author(s) -
Geometric aspects of noncommutative wormholes with conformal symmetry
This paper investigates traversable wormhole solutions within the framework of (Formula presented) f(Q,T) gravity by incorporating conformal symmetry and employing a Lorentzian distribution to model the matter sources. The study considers different equations of state, such as traceless and barotropic forms, to explore their impact on the viability of wormhole solutions. A comprehensive analysis of the effects of the model parameters on the wormhole geometry and its physical properties is carried out. The findings reveal that the resulting shape function satisfies all the necessary wormhole conditions. Importantly, certain scenarios are identified where the wormhole can be supported by non-exotic matter, highlighting the physical plausibility of such solutions within modified gravity. 2026 IOP Publishing Ltd.

Rheology-dependent surface wave characteristics in an advanced geomaterial flexoelectric plate with viscoelastic coating
This study investigates the transmission of seismic surface waves in a composite framework comprising a viscoelastic layer overlying a flexoelectric material. The study focuses on understanding the impact of different viscoelastic models (Maxwell, Newtonian, and Kelvin-Voigt) and interface conditions (smooth and welded contact) on the damping and dispersion characteristics of these waves. To achieve this, the study employs a variable-separable technique and appropriate boundary conditions to derive complex frequency relations for electrically open and short circuits scenarios. These relations are subsequently divided into real and imaginary parts to examine the dispersion and dampening properties, respectively. Numerical simulations are conducted to analyze the response of flexoelectric coefficient, viscoelastic layer thickness, and bonding parameter on phase velocity and dampening coefficient. The research findings indicate that the attenuation properties of the Maxwell and Newtonian models are lower compared to the Kelvin-Voigt model. Graphical comparisons highlight the influence of viscoelastic models and interface characteristics on wave propagation. This research can help in the development of sensors, energy harvesters, and wave manipulation devices that employ flexoelectric materials with viscoelastic coatings. Knowledge of surface wave dynamics in these structures is vital for their optimal performance. 2024 IOP Publishing Ltd.

Magnetization induced skyrmion dynamics of a spin-orbit-coupled spinor condensate under sinusoidally varying magnetic field
We explore the spin texture dynamics of a harmonically trapped spin-1 BoseEinstein condensate with Rashba spinorbit coupling and ferromagnetic spin-exchange interactions under a sinusoidally varying magnetic field along the x-direction. This interplay yields an intrinsic spin texture in the ground state, forming a linear chain of alternating skyrmions at the saddle points of the magnetic field. Our study analyzes the spin-mixing dynamics for both a freely evolving and a controlled longitudinal magnetization. The spin-1 system exhibits the Einsteinde Haas effect for the first case, for which an exchange between the total orbital angular momentum and the spin angular momentum is observed, resulting in minimal oscillations about the initial position of the skyrmion chain. However, for the fixed magnetization dynamics, the skyrmion chain exhibits ample angular oscillations about the equilibrium position, with the temporary formation of new skyrmions to facilitate the oscillatory motion. For the case of fixed magnetization, this contrast now stems from the exchange between the canonical and spin-dependent contribution to the orbital angular momentum. The variation in canonical angular momentum is linked to the angular oscillations, while the spin-dependent angular momentum accounts for the creation or annihilation of skyrmions. We confirm the presence of scissors mode excitations in the spin texture due to the angular skyrmion oscillations. 2025 The Author(s).

Can stochastic clocks in FLRW minisuperspace prevent dynamical singularities?
We develop a stochastic extension of the Wheeler-DeWitt equation in Friedmann-Lemare-Robertson-Walker (FLRW) minisuperspace and show that quantum backreaction can dynamically regulate the big bang singularity without imposing external boundary conditions. Using Laplace-Beltrami (LB) quantisation and an open-system treatment of coarse-grained graviton modes, we obtain a stochastic Hamiltonian evolution equation in which the diffusion coefficient takes the form ? ( a ) ? a 2 . This multiplicative noise vanishes at the origin and renders a = 0 an entrance boundary in Fellers classification, leading to super-exponential suppression of the LB weighted stationary density and zero probability flux into the singular point. At large scale factor, the global behaviour depends on the cosmological sector: de Sitter and positive potential-dominated regimes exhibit power-law stationary tails, whereas confining potentials or negative effective cosmological constant lead to an entrance boundary at infinity and a globally normalisable steady state. Taken together, these results indicate that stochastic backreaction arising from semiclassical coarse-graining provides a consistent and dynamical mechanism for singularity avoidance in minisuperspace quantum cosmology. 2026 IOP Publishing Ltd.

Separated/Divorced Individuals Experiences with the Legal System in India: A Qualitative Inquiry
This study identifies systemic flaws and biases in the Indian judicial system, highlighting areas for reform. Through purposive sampling, 15 separated/divorced participants (nine male, six female) were analyzed via semi-structured interviews and Interpretative Phenomenological Analysis (IPA) using Atlas.ti 23 software. Analysis derived one group experiential theme: Judicial Process and Law Enforcement, with four sub-themes: The Contradictory Positions of the Court, Nonchalance toward False Accusations, Encounter with Legal Professionals, and Two Sides of Law Enforcement. Participants revealed conflicting experiences, with few achieving justice while others faced substantial delays. Male participants often encountered allegations without evidence. Regardless of gender, feelings of distress and helplessness were prevalent due to court procedures. The findings highlight the urgent need for reforms like procedural transparency to mitigate the trauma of divorce in India and emphasize a gap in existing literature on judicial effects in separation cases. Recommendations for future research are suggested. 2025 Taylor & Francis Group, LLC. -
Development of Mindfulness Based Solution Focused Brief Therapy for Children (MBSFT-C): An International Delphi Study
Internalizing and externalizing behavioral issues among children tend to appear together and are often interrelated. A combination of Solution-focused brief therapy (SFBT) and Mindfulness is theoretically promising in reducing the co-occurrences of internalizing and externalizing issues. In this study, we developed and validated MBSFT-C, which addresses internalizing and externalizing behavioral issues. Preliminary components of MBSFT-C were developed, integrating the philosophies of Mindfulness and Solution Focused Brief Therapy. We used a two-round Delphi survey to finalize and validate these components. In the first round, the experts provided a free-text review of the initial components of MBSFT-C, which were then analyzed thematically using QDA Miner v2.0.9 software. In the second round, the experts evaluated the final components of MBSFT-C and reached a consensus using a 10-point visual analog scale. Thematic analysis of review 1 revealed three themes, Validation, Additions, and Modifications, based on which the final draft of MBSFT-C was developed. The final draft included two major components, Mindful Solution Focused Engagement and Family Mindfulness Skills. All the components of MBSFT-C achieved international expert consensus with a 70% agreement in review 2. The mean score for components by the experts ranged between 7.50 and 8.00 out of 10 on a visual analog scale, with a standard deviation ranging from 1.94 to 2.95. MBSFT-C will provide clinicians with a well suited, empirically developed, manualized comprehensive therapy that meets the special requirements of children. 2025 Taylor & Francis Group, LLC. -

The study further identified the role of internal dialogue, emotional reliance, grit, and mindfulness in strengthening family bonds. Despite a limited sample, findings showed the importance of open communication and cultural preservation in inculcating strong familial relationships. These findings provide a foundation for further research and family therapy interventions to strengthen scheduled tribe family bonds through culturally sensitive approaches. 2025 Taylor & Francis Group, LLC. -
Rethinking hope in the lives of transgender women in sex work in India: an IPA study
Background: Transgender women engaged in sex work often navigate lives shaped by stigma, precarity, and systemic exclusion; within such contexts, hope becomes a complex and negotiated experience. However, its lived meanings and processes of meaning-making remain insufficiently understood within psychological research. Objectives: To explore the lived experiences and meaning-making processes of hope among transgender sex workers in India within the socio-cultural and political context. Method: This study uses an interpretative phenomenological approach to understand the meaning-making of hope in the lives of transgender women in sex work, and the influence of sociocultural and political factors on hope. Semi-structured interviews were conducted with seven people in India who identify as transgender women and are engaging in sex work either part-time or full-time. The data were analyzed according to the guidelines laid down by Smith etal. Results: Findings revealed nine superordinate themes: compelled to actively build hope for survival, movement from interpersonal to intrapersonal hope, education and employment as sources of hope, body as a site of hope as well as hopelessness, sex work as an existential double-bind, hope forged in crisis, social influences of hope, anticipatory hope for legal provisions, and cultural and religious influences on hope. Conclusion: The study reconceptualizes hope as a survival labor, shaped by intersecting identities and lived adversities. It contributes to feminist, queer, and existential scholarship while offering implications for policymaking and the development of trauma-informed, trans-affirmative psychotherapeutic interventions. 2026 Taylor & Francis Group, LLC. -
Meaning-making, identity, and community: Cultural and religious influences on the mental health of transgender (Hijra) women in South India
Background: Hijra women in South India navigate mental health within contexts marked by structural exclusion, religious ambivalence, and complex kinship networks. While minority stress theory explains the psychological impact of stigma and discrimination, less attention has been paid to how culturally embedded meaning-making processes shape resilience and well-being in this population. Methods: This qualitative study draws on semi-structured, in-depth interviews with 13 self-identified Hijra women from Karnataka, Kerala, and Tamil Nadu. Interviews were conducted in regional languages and analyzed using Braun and Clarkes thematic analysis. The study integrates minority stress theory with a meaning-making framework to examine how cultural and religious contexts influence mental health, identity negotiation, and community relationships. Results: Three interconnected themes emerged: (1) Minority Stress and Systemic Oppression, characterized by family rejection, religious exclusion, public stigma, and economic marginalization; (2) Living in Ambivalence, reflecting both solidarity and constraint within Hijra kinship networks; and (3) Meaning-Making through Identity, Work, Community, and Spirituality. Educational attainment did not consistently translate into improved livelihoods or reduced distress. Participants constructed dignity and purpose through gender affirmation, creative and ethical livelihoods, contribution to others, and selective engagement with spiritual or ethical frameworks. Conclusions: Mental health among Hijra women is shaped by the interaction of structural exclusion and culturally embedded resources for meaning-making. Findings extend minority stress research by demonstrating how resilience emerges relationally within ambivalent social and religious environments. Culturally grounded mental health interventions must therefore address structural injustice while supporting community-based and meaning-oriented coping processes. 2026 Taylor & Francis Group, LLC. -
An educational animation intervention to enhance HPV awareness and practices among transgender individuals associated with NGOs in North India: Preliminary findings
Background: Transgender individuals in India face an elevated risk of Human Papillomavirus (HPV) infection due to limited knowledge, awareness, and access to preventive care. However, targeted research and interventions for this population are scarce. Addressing this gap is critical for improving HPV-related health outcomes among transgender individuals. Aim: This pilot study aimed to develop and evaluate the effectiveness of an animation-based intervention designed to enhance knowledge, attitudes, and practices (KAP) related to HPV among transgender individuals in India. Methods: The study was conducted in four phases among sixteen participants from different NGOs in North India. Phase 1 involved a needs analysis through a focus group discussion (FGD) with ten transgender participants, which led to co-designing the intervention. Phase 2 focused on developing the animation intervention based on the identified needs and existing literature. Phase 3 tested the intervention with six participants using a pre-post assessment with the Knowledge, Attitude, and Practice (KAP) Questionnaires and Human Papillomavirus Knowledge Questionnaire (HPV-KQ) questionnaires. Phase 4 finalized the module by incorporating feedback from the transgender community, with minor modifications made following validation. Results: Preliminary analysis showed significant improvement in KAP scores (Knowledge: 0.167 to 1.000, p = 0.073; Attitude: 0.583 to 0.833, p = 0.132; Practice: 0.250 to 0.500, p = 0.200) post-intervention. Participants demonstrated increased knowledge and more positive attitudes toward HPV prevention. Feedback highlighted the animations effectiveness in simplifying complex health information. Conclusion: The animation-based intervention effectively improved HPV-related knowledge, attitudes, and practices among transgender individuals, demonstrating the potential of culturally sensitive, visual interventions to enhance public health outcomes in underserved populations. 2025 Taylor & Francis Group, LLC. -
Capitalizing on diversity: Role of entrepreneurial and firm attributes in rural MSMEs financial accessibility
Consistent access to credit from formal financial institutions has been a significant challenge for micro-, small, and medium-sized enterprises (MSMEs) in rural areas. Despite contributing to a majority of the workforce in the economy, their failure rates continue to rise. These often indicate an inadequacy in internal determinants, such as limited access to infrastructure, inefficient managerial competencies, low entrepreneurial orientation, and other firm-related attributes. This article investigates how entrepreneurial and firm-specific traits influence the financial accessibility of rural MSMEs in the northeastern state of Assam in India while also considering the role of credit rationing. The current study data were collected from MSME entrepreneurs and analyzed using thematic analysis to explore the variables impacting credit accessibility. The results reveal that entrepreneurial (motivation, education, entrepreneurial orientation) and firm characteristics (firm size, infrastructure, technical know-how) are critical in assessing lenders perception toward borrowers in the complex loan processes. 2025 International Council for Small Business. -
Unveiling the Impact of Adverse Childhood Experiences on Adult Criminal Behavior: A Qualitative Enquiry
This qualitative study explored how adverse childhood experiences contribute to criminal behavior among 20 male prisoners (aged 2040) in Kerala. Using semi-structured interviews, thematic analysis revealed seven key themes: family dysfunction, emotional struggle, abuse, economic struggle, peer pressure, coping mechanisms, and sensation seeking. Findings showed that family dysfunction creates baseline trauma, fostering emotional voids and maladaptive coping. The study emphasizes the interconnectedness of multiple adversities in shaping criminality. It highlights the need for early interventions addressing trauma, emotional dysregulation, and unhealthy coping patterns through supportive networks to prevent criminal behavior later in life. 2025 Taylor & Francis Group, LLC. -
Women in security services: a (post)feminist reading of Lt Col Nitisha v Union of India
The role of women in Indian security services was debated in the recent judgement, Lt Col Nitisha v Union of India. The Supreme Court invalidated the impugned selection criteria and their retrospective application upon female staff as instances of indirect discrimination. This case note identifies three major implications regarding the gendered nature of the debate. Firstly, the Courts findings reveal that the government adopted certain strategic modes of postfeminist governmentality to utilize the discourse of women empowerment for departmental ends. Secondly, popular readings of the judgement risk being reduced to postfeminist cultural sensibilities, which romanticize individualistic agency and manufacture isolated struggling heroes to eventually dull the cross-sectoral feminist solidarity. Lastly, the Courts progressive doctrinal turn still construed women officials as mere employees-beneficiaries mostly claiming careerist interests. It abandoned any holistic appraisal of the role of women in military service, thereby articulating an impoverished account of female agency, dignity, and personhood. 2025 Informa UK Limited, trading as Taylor & Francis. -

Energy-efficient and secure routing strategy for opportunistic data transmission in WSNs
Driven by the critical importance of routing in Wireless Sensor Networks (WSNs) and the security vulnerabilities present in existing protocols, this research aims to address the key challenges in securing WSNs. Many current routing protocols focus on computational efficiency but fall short of providing strong security measures, leaving them vulnerable to malicious attacks. Reactive protocols, often preferred for their reduced bandwidth usage, heighten security concerns due to their limited resources for maintaining network routes, while proactive alternatives require more resources. Additionally, the ad hoc nature and energy limitations of WSNs make traditional security models, designed for wired and wireless networks, impractical. To overcome these limitations, this paper introduces the Secured Energy-Efficient Opportunistic Routing Scheme for sustainable WSNs. The proposed protocol is designed to enhance security by continuously updating neighbor information and verifying the validity of routing parameters, while also being power-aware, a critical factor given the energy constraints of WSNs. The protocol has been evaluated through simulation experiments, measuring key performance indicators such as throughput, average end-to-end delay (E2 delay), energy consumption, and network lifetime. The results demonstrate that the proposed protocol effectively strengthens WSN security while addressing the unique operational constraints of these networks. 2024 The Author(s).

Predicting sustainable equity indices using deep long short-term memory neural network: Evidence from developed and emerging markets
The present study aims to propose a predictive model to forecast the sustainable stock indices. For this, the Long Short-Term Memory (LSTM) neural network model is applied through Keras and TensorFlow to closing values of six developed and emergingmarkets: the US, the UK, Japan, Brazil, South Africa, and China. Further, the Adam optimiser and mean squared error loss function are used to train the model. To gauge the superiority of the LSTM model, a rolling window Autoregressive Integrated Moving Average (ARIMA) model is also employed. The performance accuracy of both models is evaluated using the Root Mean Square Error (RMSE), Mean Absolute Percentage Error (MAPE), and R-squared (R2). The LSTM model, with two LSTM and two dense layers, yields the best results, achieving the highest precision in predicting the values of sustainable indices. The values of RMSE and MAPE confirmed this, and the accuracy is also verified by the R2 values. LSTM shows superior predictive accuracy and is indicated to be fit for non-linear market patterns than rolling window ARIMA. The study enables policymakers and practitioners to forecast these indices and design policies to motivate related investments. 2026 The Author(s).
