description: The evolution of brown dwarfs from L to T spectral types is one of the least understood aspects of the ultracool population, partly for lack of a large, well-defined, and well-characterized sample in the L/T transition. To improve the existing census, we have searched $\approx$28,000 deg$^2$ using the Pan-STARRS1 and WISE surveys for L/T transition dwarfs within 25 pc. We present 130 ultracool dwarf discoveries with estimated distances $\approx9-130$ pc, including 21 that were independently discovered by other authors and 3 that were previously identified as photometric candidates. Seventy-nine of our objects have near-IR spectral types of L6-T4.5, the most L/T transition dwarfs from any search to date, and we have increased the census of L9-T1.5 objects within 25 pc by over 50%. The color distribution of our discoveries provides further evidence for the "L/T gap," a deficit of objects with $(J-K)_{\rm MKO}\approx0.0-0.5$ mag in the L/T transition, and thus reinforces the idea that the transition from cloudy to clear photospheres occurs rapidly. Among our discoveries are 31 candidate binaries based on their low-resolution spectral features. Two of these candidates are common proper motion companions to nearby main sequence stars; if confirmed as binaries, these would be rare benchmark systems with the potential to stringently test ultracool evolutionary models. Our search also serendipitously identified 23 late-M and L dwarfs with spectroscopic signs of low gravity implying youth. Finally, we identify 10 candidate members of nearby young moving groups (YMG) with spectral types L7-T4.5, including three showing spectroscopic signs of low gravity. If confirmed, any of these would be among the coolest known YMG members and would help to determine the effective temperature at which young brown dwarfs cross the L/T transition. (Abridged)

Central Engine and Host Galaxy of RXJ 1301.9+2747: A Multiwavelength View of a Low-mass Black Hole Active Galactic Nuclei with Ultra-soft X-ray Emission

description: RXJ 1301.9+2747 is an optically identified very low mass AGN candidate with M_BH~1x10^6M_sun, which shows extremely soft X-ray emission and unusual X-ray variability in the form of short-lived flares. We present an analysis of multiwavelength observations of RXJ 1301.9+2747 in order to study the properties of the active nucleus and its host galaxy. The UV-to-X-ray spectrum in the quiescent state can be well and self-consistently described by a thermal and a Comptonized emission from accretion disk, with blackbody dominating ~70% of the X-rays in the 0.2-2 keV. The same model can describe the X-ray spectrum in the flare state but the Comptonized component becomes dominant (~80%). The best-fit implies an Eddington ratio of ~0.14, and a black hole mass of 1.7-2.8x10^6M_sun, in agreement with the estimation from the optical data within errors. However, the best-fitting model under-predicts the optical flux for the HST point source by a factor of ~2. The excess of nuclear optical emission could be attributed to a nuclear stellar cluster which is frequently seen in low mass AGNs. The X-ray to optical spectral slope (alpha_ox) is lower than in most other active galaxies, which may be attributed to intrinsically X-ray weakness due to very little hot and optically thin coronal emission. We performed a pilot search for weak or hidden broad emission lines using optical spectropolarimetry observations, but no any polarized broad lines are detected. The host galaxy appears to be a disk galaxy with a boxy pseudobulge or nuclear bar accounting for ~15% of the total starlight, which is consistent with the general characteristics of the host of low mass AGNs.

Isolation and semi-synthesis of enterocin analogues as novel antibiotics

Publisher: name: Macquarie University

Subjects: Other education not elsewhere classified

description: Enterocin, a uniquely-structured polyketide, was first isolated in 1976 from two soil Streptomyces with reported broad-spectrum bacteriostatic activity. In this thesis, the chemical and biological properties of enterocin were re-investigated for its suitability as a next-generation antibiotic scaffold. Importantly, enterocin was found to be less stable than previously reported, undergoing a facile intramolecular rearrangement to a novel polycyclic ketal isomer bereft of antibacterial activity. Enterocin also undergoes further, undocumented degradation under neutral and basic conditions in a range of solvents at room temperature. Semi-synthetic derivatisation of enterocin at its carbonyl and secondary hydroxy positions yielded five new analogues with improved stabilities, albeit with reduced antibacterial activities. These analogues may have applications as pro-drugs to increase the antibiotic bioavailability and half-life. Furthermore, a microbial biodiscovery study was conducted to investigate the co-metabolite profile of an enterocinproducing culture, Streptomyces sp. MST-MA9095. Six α-pyrones related to enterocin were isolated from the culture on an optimised culture medium, four of which showed moderate antibacterial activities against Micrococcus luteus. Preliminary investigations into the mode of action of enterocin suggest that its true ecological role may not be as an antibiotic, but rather as a first-in-class broad-spectrum regulator of secondary metabolite production of other microorganisms.

description: The order parameter of bulk two-dimensional superconductors is classified as nodal, if it vanishes for a direction in momentum space, or gapful if it does not. Each class can be topologically nontrivial if Andreev bound states are formed at the edges of the superconductor. Non-magnetic impurities in the superconductor affect the formation of Andreev bound states and can drastically change the tunneling spectra for small voltages. Here, we investigate the mean current and its fluctuations for two-dimensional tunnel junctions between a normal-metal and unconventional superconductors by solving the quasi-classical Eilenberger equation self-consistently, including the presence of non-magnetic impurities in the superconductor. As the impurity strength increases, we find that superconductivity is suppressed for almost all order parameters since (i) at zero applied bias, the effective transferred charge calculated from the noise-current ratio tends to the electron charge $e$ and (ii) for finite bias, the current-voltage characteristics follows that of a normal state junction. There are notable exceptions to this trend. First, gapful nontrivial (chiral) superconductors are very robust against impurity scattering due to the linear dispersion relation of their surface Andreev bound states. Second, for nodal nontrivial superconductors, only p_x-wave pairing is almost immune to the presence of impurities due to the emergence of odd-frequency s-wave Cooper pairs near the interface. Owing to their anisotropic dependence on the wave vector, impurity scattering is an effective pair breaking mechanism for the rest of nodal superconductors. All these behaviors are neatly captured by the noise-current ratio, providing a useful guide to find experimental signatures for unconventional superconductivity.

Physical Adsorption at the Nanoscale: Towards Controllable Scaling of the Substrate-Adsorbate van der Waals Interaction

description: The Lifshitz-Zaremba-Kohn (LZK) theory is commonly considered as the correct large-distance limit for the van der Waals (vdW) interaction of adsorbates (atoms, molecules, or nanoparticles) with solid substrates. In the standard approximate form, implicitly based on "local" dielectric functions, the LZK approach predicts universal power laws for vdW interactions depending only on the dimensionality of the interacting objects. However, recent experimental findings are challenging the universality of this theoretical approach at finite distances of relevance for nanoscale assembly. Here, we present a combined analytical and numerical many-body study demonstrating that physical adsorption can be significantly enhanced at the nanoscale. Regardless of the band gap or the nature of the adsorbate specie, we find deviations from conventional LZK power laws that extend to separation distances of up to 10--20 nanometers. Comparison with recent experimental observation of ultra long-ranged vdW interactions in the delamination of graphene from a silicon substrate reveals qualitative agreement with the present theory. The sensitivity of vdW interactions to the substrate response and to the adsorbate characteristic excitation frequency also suggests that adsorption strength can be effectively tuned in experiments, paving the way to an improved control of physical adsorption at the nanoscale.

Domain-specific query languages

description: Data is a valuable commodity, and while there are many methods for effectively processing data, at the core of many of these is a query language - either general purpose, such as SQL and SPARQL, or domain-specific. Examples of the latter are query languages for linguistic annotations such as LPath+ and EmuQL. Domain-specific query languages allow greater expressiveness as they are more suited to a chosen data model. But what is the best way of creating such a query language, so as to ensure that the query system created is most suited to the task? Why do the query languages in the same domain vary so widely? Are some more expressive than others, or are they all just different surface forms of the same abstract query language? This study analyses and compares two query languages specific to the domain of linguistic annotations as examples of domain-specific query languages. It examines the structure ofthe query languages, as well as their levels of expressiveness in comparison to each other, relative to the questions that are being asked. Versions of each language are implemented to work with a unified data model, and so the questions asked of each will be the same. The end result is that whilst both can answer most questions and can be reduced to a singular query model, they may be limited by the data and interpreter used.

description: Abstract

This study investigates the anti-inflammatory and cytoprotective effects of beta-chitosan-derived zinc nanoparticles (ZnNPs) on lipopolysaccharide (LPS)-induced inflammation in 3T3 cells. Synthesized using a green approach, the nanoparticles were characterized through FTIR, UV-Vis spectroscopy, and XRD analyses, confirming their stable formation. FTIR spectra identified key functional groups, including the Zn-O bond, while UV-Vis spectroscopy showed a characteristic absorption peak at 360 nm. XRD patterns revealed the crystalline nature of ZnO nanoparticles within the beta-chitosan matrix. The biological efficacy was assessed using the MTT assay and gene expression studies. The MTT assay demonstrated a significant, dose-dependent improvement in cell viability, indicating protection against LPS-induced cytotoxicity. Gene expression analysis showed that the ZnNPs significantly downregulated pro-inflammatory cytokines IL-2, IL-6, and TNF-α, while upregulating the anti-inflammatory cytokine TGF-β, mitigating the inflammatory response. Additionally, the nanoparticles modulated apoptotic markers by decreasing Bax (pro-apoptotic) and increasing Bcl-2 (anti-apoptotic) expression, promoting cell survival. These findings highlight the potential of beta-chitosan-derived Zn nanoparticles as therapeutic agents for managing inflammation and protecting against inflammation-induced cell damage, paving the way for future in vivo studies and clinical applications.

description: We decompose the observed 7.7 $μ$m polycyclic aromatic hydrocarbon (PAH) emission complexes in a large sample of over 7000 mid-infrared spectra of the interstellar medium (ISM) using spectral cubes observed with the Spitzer/IRS-SL instrument. In order to fit the 7.7 $μ$m PAH emission complex we invoke four Gaussian components which are found to be very stable in terms of their peak positions and widths across all of our spectra, and subsequently define a decomposition with fixed parameters which gives an acceptable fit for all the spectra. We see a strong environmental dependence on the inter-relationships between our band fluxes - in the HII regions all four components are inter-correlated, while in the reflection nebulae (RNe) the inner and outer pairs of bands correlate in the same manner as previously seen for NGC~2023. We show that this effect arises because the RNe maps are dominated by strongly irradiated PDR emission, while the much larger HII region maps are dominated by emission from regions much more distant from the exciting stars, leading to subtly different spectral behavior. Further investigation of this dichotomy reveals that the ratio of two of these components (centered at 7.6 and 7.8 $μ$m) is linearly related to the UV field intensity (log G$_0$). We find that this relationship does not hold for sources consisting of circumstellar material, which are known to have variable 7.7 $μ$m spectral profiles.

description: The Asteroid Belt is characterized by the radial mixing of bodies with different physical properties, a very low mass compared to Minimum Mass Solar Nebula expectations and has an excited orbital distribution. Models of the evolution of the Asteroid Belt show that the origin of its structure is strongly linked to the process of terrestrial planet formation. The Grand Tack model presents a possible solution to the conundrum of reconciling the small mass of Mars with the properties of the Asteroid Belt, including the mass depletion, radial mixing and orbital excitation. However, while the inclination distribution produced in the Grand Tack model is in good agreement with the one observed, the eccentricity distribution is skewed towards values larger than those found today. Here, we evaluate the evolution of the orbital properties of the Asteroid Belt from the end of the Grand Tack model (at the end of the gas nebula phase when planets emerge from the dispersing gas disk), throughout the subsequent evolution of the Solar System including an instability of the Giant Planets approximately 400 My later. Before the instability, the terrestrial planets were modeled on dynamically cold orbits with Jupiter and Saturn locked in a 3:2 mean motion resonance. The model continues for an additional 4.1 Gy after the giant planet instability. Our results show that the eccentricity distribution obtained in the Grand Tack model evolves towards one very similar to that currently observed, and the semimajor axis distribution does the same. The inclination distribution remains nearly unchanged with a slight preference for depletion at low inclination; this leads to the conclusion that the inclination distribution at the end of the Grand Tack is a bit over-excited.

description: In an ever-expanding world of domain-specific knowledge, the increasing complexity of consuming, and storing information necessitates the generation of summaries from large information repositories. However, every persona of a domain has different requirements of information and hence their summarization. For example, in the healthcare domain, a persona-based (such as Doctor, Nurse, Patient etc.) approach is imperative to deliver targeted medical information efficiently. Persona-based summarization of domain-specific information by humans is a high cognitive load task and is generally not preferred. The summaries generated by two different humans have high variability and do not scale in cost and subject matter expertise as domains and personas grow. Further, AI-generated summaries using generic Large Language Models (LLMs) may not necessarily offer satisfactory accuracy for different domains unless they have been specifically trained on domain-specific data and can also be very expensive to use in day-to-day operations. Our contribution in this paper is two-fold: 1) We present an approach to efficiently fine-tune a domain-specific small foundation LLM using a healthcare corpus and also show that we can effectively evaluate the summarization quality using AI-based critiquing. 2) We further show that AI-based critiquing has good concordance with Human-based critiquing of the summaries. Hence, such AI-based pipelines to generate domain-specific persona-based summaries can be easily scaled to other domains such as legal, enterprise documents, education etc. in a very efficient and cost-effective manner.

description: The correspondence between the edge theory and the entanglement spectrum is firmly established for the chiral topological phases. We study gapped, topologically ordered, non-chiral states with a conserved $U(1)$ charge and show that the entanglement Hamiltonian contains not only the information about topologically distinct edges such phases may admit, but also which of them will be realized in the presence of symmetry breaking/conserving perturbations. We introduce an exactly solvable, charge conserving lattice model of a $\mathbb{Z}_2$ spin liquid and derive its edge theory and the entanglement Hamiltonian, also in the presence of perturbations. We construct a field theory of the edge and study its RG flow. We show the precise extent of the correspondence between the information contained in the entanglement Hamiltonian and the edge theory.

Microspheres in the vicinity of a bifurcation at moderate Reynolds numbers

Publisher: name: Macquarie University

description: In microfluidic filtration processes a mixture of particles in a suspension are separated by applying external forces on microparticles to displace particles of different characteristics. Microfluidic continuous flow filtration methods are passive filtration methods that separate particles by using a boundary that causes the particles to cross streamlines to be collected at different outputs. These methods can offer some advantages over other filtration methods as they require relatively small sample sizes and they prevent clogging, making the process efficient and cost effective. The devices used in this practice do not require a filter membrane which obstructs the particle path and often needs to be replaced. This means a range of particle sizes can be filtered using this method as long as they are small enough to pass through the channel of a device. One particular approach to microfluidic continuous flow filtration uses channels with bifurcating channels of different flow rates to move particles of different sizes along different streamlines. This paper describes the motion of particles at the flow boundaries of these bifurcations at low to moderate Reynolds numbers to see if the fate of the particles near this boundary are affected by Reynolds numbers. This will be studied by running a stream of different sized polymer beads near a bifurcation and making observations of the particle path at different flow rates.

description: Abstract

Kidney disease is a “Hidden epidemic” that affected more than 850 million people worldwide according to a multinational study survey in the year 2023 by ISN‐GKHA. There was a large increase in the prevalence of kidney disease. It was estimated that in the next few years, India may lead among countries in kidney disease[1]. The Patients undergoing hemodialysis are usually experiencing RLS frequently. A restless leg syndrome (RLS) is a neurological condition characterized by an overwhelming need to move the legs, frequently in the presence of discomfort. The potential effectiveness of non‐pharmacological therapies in treating RLS symptoms is examined in this feasibility study. RLS will always disturb sleep[2]. The researcher employed a non‐equivalent Control group in a quasi‐experimental design for this study. The Abirami Kidney Center in Karur was the site of the study. Screening was done with a checklist and modified restless leg syndrome severity rating scale. Among the 72 hemodialysis patients, 30 patients with RLS were studied. 15 samples are allotted for the study group and 15 for the control group. The interventions were given to the study group[3]. According to the results, under level of symptoms, Quality of life and sleep there was much significant difference between pretest and post test among experimental group. The control group does not exhibit a significant difference[4]. According to this study, effleurage massage therapy, foot reflex ology and IEC on sleep hygiene were helpful in helping hematolysis patients sleep better and experience a reduction in symptoms of restless leg syndrome and quality of life. The findings from this feasibility study have the potential to inform the development of larger‐scale trials and contribute valuable insights into the role of non‐pharmacological interventions in managing RLS.
Adults' constructions of an early childhood music class: lived experience and cultural reproduction

description: The provision of extra-curricular or enrichment activities for young children has boomed in recent years. This thesis offers an ethnographic study of a specific class in an early childhood music (ECM) program held at a regional Conservatorium of Music, exploring how adult participants (teachers, administrators, and carers) construct the class. Using interviews, participant observation, field notes, questionnaires and video recordings as my primary methodological tools, I present a picture of the construction of the ECM class through adults' diverse expectations, perceptions, life histories, beliefs and behaviours. I look to the substantial body of cultural reproduction literature which has grown from the example of Bourdieu; in particular I make use of the literature on class-specific parenting strategies which are argued to facilitate the "transmission of differential advantages" (Lareau, 2011, p. 5). I seek to contextualize participation in early years' enrichment activities in processes of cultural reproduction without denying the meaningful and affective relationship participants have with the class.

description: We report on the discovery of a new fast radio burst, FRB 150215, with the Parkes radio telescope on 2015 February 15. The burst was detected in real time with a dispersion measure (DM) of 1105.6$\pm$0.8 pc cm^{-3}, a pulse duration of 2.8^{+1.2}_{-0.5} ms, and a measured peak flux density assuming the burst was at beam center of 0.7^{+0.2}_{-0.1} Jy. The FRB originated at a Galactic longitude and latitude of 24.66^{\circ}, 5.28^{\circ}, 25 degrees away from the Galactic Center. The burst was found to be 43$\pm$5% linearly polarized with a rotation measure (RM) in the range -9 < RM < 12 rad m^{-2} (95% confidence level), consistent with zero. The burst was followed-up with 11 telescopes to search for radio, optical, X-ray, gamma-ray and neutrino emission. Neither transient nor variable emission was found to be associated with the burst and no repeat pulses have been observed in 17.25 hours of observing. The sightline to the burst is close to the Galactic plane and the observed physical properties of FRB 150215 demonstrate the existence of sight lines of anomalously low RM for a given electron column density. The Galactic RM foreground may approach a null value due to magnetic field reversals along the line of sight, a decreased total electron column density from the Milky Way, or some combination of these effects. A lower Galactic DM contribution might explain why this burst was detectable whereas previous searches at low latitude have had lower detection rates than those out of the plane.

description: Mass outflow generated by the dynamical feedback from massive stars is currently a topic of high interest. Using a purpose-developed analysis technique, and taking full advantage of the high kinematic and angular resolution of our instrument we have detected a number of expanding superbubbles in the interacting pair of galaxies Arp 244 (NGC 4038/9) commonly known as the Antennae. We use a Fabry-Pérot interferometer GHαFaS to measure the profile of Hα in emission over the full extent of the object, except for the extended HI tails. The superbubbles are found centred on most of the brightest HII regions, especially in the overlap area of the two merging galaxies. We use measured sizes, expansion velocities and luminosities of the shells to estimate most of the physical parameters of the bubbles, including the kinetic energy of the expansion. In order to assess the validity of our results and approximations we perform a hydrodynamic simulation and manage to reproduce well our best measured superbubble with reasonable physical input assumptions. We also study the sources of ionization of the shells, finding that at the current, quite late stage of expansion, radiation from the remaining stars dominates, though the effect of supernova shocks can still be noted.

A rotationally-powered magnetar nebula around Swift J1834.9-0846

description: A wind nebula, generating extended X-ray emission, was recently detected surrounding Swift J1834.9-0846. This is the first magnetar for which such a wind nebula was found. Here, we investigate whether there is a plausible scenario where the pulsar wind nebula (PWN) can be sustained without the need of advocating for additional sources of energy other than rotational. We do this by using a detailed radiative and dynamical code that studies the evolution of the nebula and its particle population in time. We find that such a scenario indeed exists: Swift J1834.9-0846's nebula can be explained as being rotationally-powered, as all other known PWNe are, if it is currently being compressed by the environment. The latter introduces several effects, the most important of which is the appearance of adiabatic heating, being increasingly dominant over the escape of particles as reverberation goes by. The need of reverberation naturally explains why this is the only magnetar nebula detected, and provides estimates for Swift 1834.9-0846's age.

Wideband Distributed Spectrum Sharing with Multichannel Immediate Multiple Access

description: This paper describes a radio architecture for distributed spectrum sharing of multiple channels among secondary users (SUs) in a wide band of frequencies and a localized area. A novel Multichannel Immediate Multiple Access (MIMA) physical layer is developed such that each SU can monitor all the channels simultaneously for incoming signals and achieve fast rendezvous within the multiple channels. The spectrum utilized by an SU pair can be changed dynamically based upon spectrum sensing at the transmitter and tracking synchronization and control messages at the receiver. Although information about the number of active SUs can be used to improve the spectrum sharing efficiency, the improvement is small relative to the cost of obtaining such information. Therefore, the architecture adopts Multichannel Carrier Sense Multiple Access (CSMA) for medium access control regardless of the number of active SUs. A prototype implementation of the architecture has been developed using an advanced software defined radio (SDR) platform. System tests demonstrate that the spectrum sharing efficiency of the prototype is close to an upper bound if the signal-to-noise ratio (SNR) is sufficiently high. Among other practical issues, imaged interference caused by hardware IQ imbalance limits system performance. In the prototype, the MIMA is based on an LTE waveform. Therefore, the spectrum sharing radio can be potentially applied to the 3.5 GHz radar band for Citizens Broadband Radio Service (CBRS).

Fragmentation of vertically stratified gaseous layers: monolithic or coalescence-driven collapse

description: We investigate, using 3D hydrodynamic simulations, the fragmentation of pressure-confined, vertically stratified, self-gravitating gaseous layers. The confining pressure is either thermal pressure acting on both surfaces, or thermal pressure acting on one surface and ram-pressure on the other. In the linear regime of fragmentation, the dispersion relation we obtain agrees well with that derived by Elmegreen & Elmegreen (1978), and consequently deviates from the dispersion relations based on the thin shell approximation (Vishniac 1983) or pressure assisted gravitational instability (Wünsch et al. 2010). In the non-linear regime, the relative importance of the confining pressure to the self-gravity is a crucial parameter controlling the qualitative course of fragmentation. When confinement of the layer is dominated by external pressure, self- gravitating condensations are delivered by a two-stage process: first the layer fragments into gravitationally bound but stable clumps, and then these clumps coalesce until they assemble enough mass to collapse. In contrast, when external pressure makes a small contribution to confinement of the layer, the layer fragments monolithically into gravitationally unstable clumps and there is no coalescence. This dichotomy persists whether the external pressure is thermal or ram. We apply these results to fragments forming in a shell swept up by an expanding H II region, and find that, unless the swept up gas is quite hot or the surrounding medium has low density, the fragments have low-mass ( ~< 3 M_Sun ), and therefore they are unlikely to spawn stars that are sufficiently massive to promote sequential self-propagating star formation.

1D atmosphere models from inversion of Fe I 630 nm observations with an application to solar irradiance studies

description: Present-day semi-empirical models of solar irradiance (SI) variations employ spectra computed on one-dimensional atmosphere models (1D models) representative of various solar surface features to reconstruct SI changes measured on timescales greater than a day. Various recent studies have, however, pointed out that the spectra synthesized on 1D models do not reflect the radiative emission of the inhomogenous atmosphere revealed by high-resolution solar observations. We aimed to derive observational-based atmospheres from such observations and test their accuracy for SI estimates. We analysed spectro-polarimetric data of the Fe I 630 nm line pair on photospheric regions representative of the granular, quiet Sun pattern (QS) and of small- and large-scale magnetic features, both bright and dark with respect to the QS. The data were taken on 2011 August 6, with the CRISP at the Swedish Solar Telescope, under excellent seeing conditions. We derived atmosphere models of the observed regions from data inversion with the SIR code. We studied the sensitivity of results to spatial resolution and temporal evolution, and discussed the obtained atmospheres with respect to several 1D models. The atmospheres derived from our study agree well with most of the compared 1D models, both qualitatively and quantitatively (differences are within 10%), but for pore regions. Spectral synthesis computations on the atmosphere obtained from the QS observations return SI between 400 nm and 2400 nm that agrees, on average, within 2.2% with standard reference measurements, and within -0.14% with the SI computed on the quiet Sun atmosphere employed by the most advanced semi-empirical model of SI variations.

Nonlinear reconnecting edge localized modes in tokamaks

description: Nonlinear edge localized modes in a tokamak are examined using global three-dimensional resistive magnetohydrodynamics simulations. Coherent current-carrying filament (ribbon-like) structures wrapped around the torus are nonlinearly formed due to nonaxisymmetric reconnecting current sheet instabilities, the so called peeling-like edge localized modes. These fast growing modes saturate by breaking axisymmetric current layers isolated near the plasma edge and go through repetitive relaxation cycles by expelling current radially outward and relaxing it back. The local bi-directional fluctuation-induced electromotive force (emf) from the edge localized modes, the dynamo action, relaxes the axisymmetric current density and forms current holes near the edge.

description: Integrating prompt literacy into sanctioned educational curricula is essential for navigating the evolving
digital landscape dominated by AI-driven tools. Current curricula predominantly focus on traditional,
subject-based instruction, leaving a gap in preparing students to interact critically and responsibly with
generative AI. Prompt literacy, defined as the ability to construct precise prompts to guide AI outputs, is a
core competency for retrieving, interpreting, and ethically managing AI-generated information. A
pedagogical model for embedding prompt literacy into the curriculum offers educational systems a
framework to adapt to rapid technological advancements. Recognizing prompt literacy as a sanctioned
skill enables learners to better handle the cognitive, ethical, and technical challenges of an AI-mediated
world, equipping them for informed and responsible engagement with AI technologies.
