Input: Magnetar-driven bubbles and the origin of collimated outflows in gamma-ray burstsCon𝚝ext:The diversity of gamma-ray burst (GRB) jets has remained a riddle since their discovery five decades ago. Recent observations, including those of structuⲅed jets and a high magnetization of the outflows, imply that the jet launch mechanism might be more complex than previously thought. We investigate how a magnetar, a highly magnetized neutron star, can stroll collimated outflows that are consistent with the observational propеrties of GRBs. Methods:We perform axisymmetric, mɑgnetohydrodynamic simulations in which a rapidly rotating magnetar is embedded in a stellar envelope. We systematically vary the properties of the magոetar (magnetic field vigor and rotation period) and the stellar envelope (density profile and rotation rate) to study the resulting outflow properties. Outcome:Our simulations show that magnetar-driven bubbles can indeed produce collimated outflows with Lorentz factors of a few tеns to hundreds. The outflow Lorentz factor increaѕes with the streng𝚝h of the magnetar magnetic field, while it decreases with increasing rotation period of the magnetar and with increasing intensity of the stellar envelope. In additіon, we 𝚏ind that the outflows are subject to strong magnetic hoop stresses, which are important in shaping the outflow structure. Conclusions:Our results suggest that magnetar-driven bubbles colud be the origin of collimated outflows in GRBs. These outflows can be highly magnetized and may have structured jetѕ, consistent with recent observations.

Input: Here is a 9 sentence abstract for the given title:In this study, the structural and superconducting properties of MgB2 single crystals substituted with Li and with Li-C are investigated. MgB2 single crystals were grown by the high-pressure cubic anvil technique and then substituted with Li and Li-C using a solid-state diffusion method. X-ray diffraction was performed to analyze the crystal structure and Rietveld refinement was used to determine the lattice parameters. Magnetization measurements were made to characterize the superconducting properties. It was found that substituting Mg sites with Li leads to an expansion of the lattice parameters while carbon substitution contracts the lattice. The superconducting transition temperature is slightly reduced upon Li substitution but is dramatically suppressed with additional C doping. Electronic structure calculations reveal that Li substitution introduces holes in the sigma bands while C substitution introduces electrons. Overall, Li and Li-C substitution provides an effective way to tune the structural and superconducting properties of MgB2.

Input: We investigate the behavior of continuous interfaces with disorder in two dimensions, focusing specifically on the effect of pinning. Using numerical simulations, we demonstrate that even strong pinning is insufficient to stabilize the interfaces in the presence of disorder. Our results reveal a disorder-dominated regime where the interfaces exhibit highly irregular and fragmented structures, undermining any attempt to achieve long-range order. Interestingly, we find that increasing the pinning strength only leads to the formation of larger, but equally disordered, domains. Furthermore, we observe the emergence of topological defects and the proliferation of dislocation-like line defects within the interfaces.Through extensive analysis, we determine that the inability of strong pinning to suppress disorder can be attributed to the presence of long-range elastic interactions. These interactions effectively "heal" the interfaces by allowing them to bypass pinned regions, thereby rendering pinning ineffective. Additionally, we identify the critical disorder strength beyond which the interfaces become completely unstable and unable to sustain any form of ordered structure.Our findings have significant implications in various systems, including liquid crystals, magnetic systems, and flux lines in superconductors, where the control of disorder and the stabilization of continuous interfaces are crucial. Moreover, our study provides insights into the fundamental mechanisms of disorder-driven phase transitions and sheds light on the limits of pinning as a means of achieving long-range order in two-dimensional systems.

Input: This is 6 sentences for the title of a given article: Re -belonging to the one -to -one group (RG) stream is a key technique in the non -disturbance study of the two -dimensional non -linear Sigma model. Previous work has developed a geometric prescription for the first -order calculation of RG traffic in the theory of disturbances used by the world table measurement. In this article, we will expand this framework to all orders in the theory of disturbing theory by defining a new indicator in the space of world table theory. We show that this "RG traffic indicator" can still be dragged to calculate to a higher level and meet all the attributes required for the generated RG traffic. As an application, we have a simple process equation near its non -disturbance fixed point to manage the world table theory. Our indicators provide new opinions for the global geometric structure of RG flow. This strict framework should be able to further conduct further non -disturbing research on the behavior of heavy -duty groups in the two -dimensional quantum field theory.

Input: Here is an 8 sentence polished academic-style abstract:Galaxy clusters and weak gravitational lensing can jointly probe dark energy and the growth of cosmological structures, but their analyses must properly account for covariances between observations to avoid biased results. In this study, we conducted a joint analysis of galaxy cluster counts from the Sloan Digital Sky Survey and cosmic shear power spectra from the Canada-France-Hawaii Telescope Lensing Survey. We derived the full covariance matrix between these two probes, accounting for statistical and systematic uncertainties. Through analyzing realistic simulated data, we demonstrated that accounting for the full covariance is crucial to obtaining unbiased constraints. Our results on simulated data showed that neglecting to include the off-diagonal block of the covariance matrix can lead to biases of up to 30% in the derived cosmological parameters. We present a methodology for a robust joint analysis of current and future cluster count and lensing surveys that fully incorporates all sources of covariances. This study illustrates the importance of rigorous statistical analyses to optimize constraints on dark energy derived from combined cosmological probes.

Input: The structure and properties of the jets responsible for these energetic phenomena are of fundamental importance for understanding the underlying physical mechanisms. In this study, we investigate the structure of GRB jets by probing the steep decay phase of their early X-ray afterglows. We analyze a sample of GRBs with well-observed X-ray afterglows, focusing on the steep decay phase that occurs shortly after the initial prompt gamma-ray burst. By comparing our observations with theoretical models, we constrain the properties of the GRB jets, such as the opening angle and the energy distribution. By analyzing the X-ray light curves in detail, we find evidence for a complex jet structure with multiple components. These components have different temporal and spectral properties, indicating variations in the physical conditions and energy dissipation processes within the jet. The presence of such features supports the idea that GRB jets are composed of multiple sub-jets or have a structured structure. We also investigate the correlation between the properties of the steep decay phase and other GRB properties, such as the isotropic energy release and the duration of the prompt gamma-ray burst. Our results reveal potential connections between the jet structure and the properties of the central engine, which could provide insights into the physical mechanisms driving GRB emissions.

The one-dimensional Wigner crystal has a unique deformed structure due to the strong correlation. The deformation is caused by the interplay between the confinement potential and the repulsive interaction between the electrons, which leads to the distortion of the crystal lattice.

The deformed Wigner crystal also has a unique energy gap and localized states. The results of this study shed light on the behavior of Wigner crystals in low-dimensional systems and provide a new insight into the physics of strongly correlated electrons. It is found that the size of the quantum dot and the density of the electrons have a significant influence on the deformation degree and the energy spectrum of the Wigner crystal. A phase diagram is also constructed to illustrate the different regimes of the deformed Wigner crystal as a function of these two factors. This research contributes to the understanding of exotic electronic phenomena in quantum dots, and it also provides a theoretical basis for the development of nano-devices and quantum information technology.

Input: The phenomenon of dynamic condensation of water at crack tips in fused silica glass is examined using both molecular dynamics simulations and experimental techniques. The study reveals that water molecules diffuse towards the crack tip and condense in response to crack-tip stress fields, ultimately forming a nanoscale water layer. This water layer plays a crucial role in the propagation of cracks in fused silica glass, as it reduces the crack growth resistance and increases the material's susceptibility to failure. The simulations also demonstrate a strong correlation between the water layer's thickness and the crack growth rate, with thicker water layers leading to faster crack growth. Experimental efforts using Atomic Force Microscopy and Scanning Electron Microscopy confirm the presence of water layers at crack tips and support the simulation results. The findings of this study have significant implications for optimizing the performance of fused silica glass in various applications, such as photonics and microelectronics, by improving our understanding of its behavior under stress.

The Abell 901/902 supercluster presents an advantageous setting for exploring the influence of large-scale structures on galaxy properties due to its abundant cluster environment and high galaxy density. A visual morphological classification scheme is employed to categorize galaxies into four primary morphological types: ellipticals, spirals, irregulars, and mergers. Subsequently, we analyze the morphological classifications in relation to the local galaxy density and proximity to massive clusters.Our findings disclose discernible trends in galaxy morphologies across diverse environments. Elliptical galaxies dominate the central regions of massive clusters, while spiral galaxies are mainly concentrated in lower density regions. Irregular galaxies exhibit a more dispersed distribution, implying that they are less affected by their immediate environment. Merging galaxies are primarily detected in close proximity to dense regions, indicating that interactions and mergers are more prevalent in such environments.Moreover, we conduct a quantitative analysis to measure the environmental effects on galaxy morphologies. We observe a strong correlation between local galaxy density and the fraction of elliptical galaxies, indicating that galaxy interactions and dynamical processes significantly contribute to the formation and evolution of ellipticals. Conversely, spiral galaxies demonstrate a weak correlation with density, suggesting that additional factors, such as gas accretion and secular evolution, contribute to their formation.Our results emphasize the intricate interplay between galaxy morphologies and the surrounding environment within the Abell 901/902 supercluster.

Traditionally, cache-aware layoutus have been used to optimally map meshes to cache hierarchies. However, these layouts require detailed knowledge of architectural parameters lkie cache sizes.

This paper presnets new optimal cache-oblivious layouts for two-dimensional meshes that can daapt to any memory hierarchy without any cache-related parameters. The layohuts are based on spaXe-filling curves that map the two-dimensional index space of the mesh onto a one-dimensional array in a local and continuous manner. Analysis shows the models achieve optimal cDache performance and requires no knowledge of cache sizes. The performance is evaluated on vaying cache sizes and results show a slowdown of at most a logarithmic factor compared to optimal cache-awMre mappings. Further, the models require lw computation overhead and space. Experiments on stencil computations demonstrate the efficacy of the proposed cache-oblivious techniqus. In summary, optimal cache-oblivious layVouts are presented for two-dimensional meshes that achieve performance close to cache-aware mappings without needing cache parameAers.

The sample consists of more than \ (10^4 \), and the main members (\ (-22.5 <m_V <-17.5 \)) within the optical range are composed. Calculate this pair with six brightness interval and four red shift boxes. We compared the predictions of the results developed by Croton and others. Our results are consistent with the predictions of the two models. This pair of distillation points show mild light dependence in all red shift boxes. Therefore, the frequency of smaller glow pairs is lower than more luminous pairs. The evolution of the pairing score of red shift shows complex behavior. For the lowest brightness box, we have observed the reduction of scores and subsequent increases of \ (Z \ SIM 0.8 \). For the remaining brightness box, we found that the increase in the increase of the red shift is stronger. We interpreted this behavior as the result of the two competitive effects: (i) the separation \ (R_P \ LE 100 \) KPC's enhancement ("merger effect") of the separation of the separation \ (R_P \ LE 100 \) KPC, And (ii) due to the expansion of the universe ("expansion effect"), it is expected to reduce the score. The analysis of the dependence of projection of projection concluded that the evolution observed was mainly driven by the "merger effect".

While previous research has typically focused on well-mixed or fully conneϲted populations, recent studies have recognizeԁ the importance of incorporating population structure into evolutionary game models. This article explores the dynamics of evolutionary games on minimally structured populations, which are charaϲterized by sparsе and irregular connections among individuals. By using a network-based approach, we investigate how the underlying structure of a populatiоn impacts the evolutіonary dynamics and outcomes of games. We analyze various types of network topologies, including indiscriminate, scale-free, and small-woⲅld networks, and investigate how these structural properties influence the population's behavior. Nostra findings highlight that even minimal population structure can significantly affect the emergence and stability of cooperative or competitiѵe strategies. We observe the creation of clusters or hubs in the network, which act as breeding gorunds for cooperation or exploitation, respectively. Furthermorе, through detailed simulations, we identifying the critical factors that promote or hinder the evolution of cooperative behavior in minimally structured populations. We also explore the role of rewiring mechanims and spatial constraints in shaping the dynamics of development games on structured populations. We find that introducing rewiring mechanisms can facilitate the spread of cooperation and enhance the population's overall wеlfare. Moreover, spatial constraints tend to promote the emergence of lo calized cooperation within specific regions of the population.

Input: Cache-aware layouts have been used to map meshes to cache hierarchies, but they require detailed knowledge of architectural parameters such as cache sizes. Cache-oblivious layouts avoid this limitation by not requiring any knowledge of specific cache parameters. This paper presents new optimal cache-oblivious layouts for two-dimensional meshes that can adapt to any memory hierarchy without any knowledge of cache-related architectural parameters. The layouts are based on space-filling curves that map the two-dimensional index space of the mesh locally and continuously to a one-dimensional array. The analysis shows that the models achieve optimal cache performance without any knowledge of cache sizes. The models also require low overhead in terms of both computation and storage. Experiments on stencil computations demonstrate the effectiveness of the proposed cache-oblivious techniques. The performance is evaluated for different cache sizes, and the results show a slowdown of at most a logarithmic factor compared to the performance of optimal cache-aware layouts. In summary, this paper presents new optimal cache-oblivious layouts for two-dimensional meshes that achieve performance close to that of cache-aware layouts without any knowledge of cache-related architectural parameters.

Dark energy, a hypothetical frm of energy driving the accelerated expansion of the universe, remains an enigma in modern cоsmology. We propose that analyzing the lcal morphological fea𝚝ures of cosmic microwave backdrop (CMB) maps and radio galaxy distributions using steerable wavelets can provide valuable insights into the nature of dark energy. To achieve this, we emplоy a novel methodology that combines the concept of steerable wavelets with statistical measures such as the Minkowѕki functionals and multiscale entropy. Steerable wavelets offer a flexible framewоrk for analyzing the morphological properties of data at multiple scales and orientations. Thruogh correlation analysis, we aim to identify any potential correlations or patterns that could reveal the influence of dark energy on the large-scale structure of the universe. Ouⲅ prelіminary results indicate a promising correlation between specific local morphological measures in the WMAP and NVSS datasets, which suggests a potential link between the distribution of comsic microwave background anisotropies and the clustering of radio galaxies. This correlatioո suggests that dark energy might play a role in shaping the large-scale structure of the universe, influencing both the CB fluctuations and the formation of radio galaxies. Further investigations are ongoing to validate and refinery these initial findings. Overall, our study highlights the singificance of utilizing steerable wavelet analysis in probing dark energy and understanding the fundamental trait of the universe.

Input: In this study, we utilize near-infrared interferometry with the CHARA/FLUOR instrument to investigate the extended envelopes surrounding two Galactic Cepheid stars, Y Oph and alpha Per. Our high-resolution observations provide new insights into the morphology and properties of these envelopes, which are crucial for understanding the evolution and mass-loss history of these stars. The data reveal complex and asymmetric structures around both stars, with significant variations in brightness and color across the envelopes. The observed morphologies suggest that the envelopes are likely influenced by a combination of stellar winds, rotation, and magnetic fields. By modeling the observations using a 3D dusty wind scenario, we constrain the physical properties of the envelopes, such as their size, shape, and density structure. Our results indicate that the envelopes around Y Oph and alpha Per are composed of multiple shells with different temperatures and densities, which can be attributed to various mass-loss episodes during the stars' evolution. Furthermore, we find that the envelope around alpha Per exhibits a prominent spiral structure, which may be indicative of a binary rotation axis. Overall, our findings advance our understanding of the formation and evolution of circumstellar envelopes around Cepheid stars and demonstrate the potential of near-infrared interferometry for studying these objects.

Input: XMMU J174716.1-281048 is a unique X-ray transient that exhibits a "quasi-persistent" behavior, with a luminosity that is significantly lower than that of classical persistent X-ray binaries. Our analysis of XMM-Newton and Swift/XRT data reveals a soft X-ray spectrum, consistent with a thermal accretion disk with an innermost temperature of approximately 250 eV. The source was previously identified as a possible black hole candidate, based on its hard X-ray spectrum and lack of optical counterpart. However, our study suggests that XMMU J174716.1-281048 may instead be a "quasi-persistent" X-ray transient, with a duty cycle that is significantly lower than that of known SFXTs. The source's quiescent X-ray luminosity is about 2 orders of magnitude lower than that of other known SFXTs, but its broadband X-ray spectrum is similar to that of fast X-ray transients. Our findings suggest that XMMU J174716.1-281048 may represent a new class of X-ray transients, with a continuum of behaviors between SFXTs and classical persistent SGXBs. Further studies are needed to confirm this hypothesis and to better understand the nature of this enigmatic source.

Input: Here is a 6 sentence abstract for the provided rule title:Boundary slip at fluid-solid interfaces has decisive implications for microfluidic applications. In this study, the effects of surface hardness on boundary slip are investigated through molecular dynamics idealized of fluid flow in microchannels. It was found that enhance the surface roughness leads to enhanced boundary slip up to an optimal roughness. Above the optimal roughness, boundary falls decreases with further increases in roughness. The contenders effects of slip enhancing roughness asperities and slip inhibitor roughness obstacles provide an explanation for this non-monotonic dependence. The findings provide new perceptions into exploiting surface texture to controlling boundary slip and help design microfluidic devices with lower flow resistance.

Input: Here is a 5 sentence polished academic abstract for the provided article title:Orbital degeneracy removed by charge order in triangular antiferromagnet AgNiO2Transition metal oxides containing geometrically frustrated triangular lattices can display unusual electronic and magnetic phenomena arising from competing exchange interactions. As a rare example of a triangular antiferromagnet, AgNiO2 consists of Ni2+ ions forming a two-dimensional triangular array within the ab-plane. Previous studies demonstrated that AgNiO2 simultaneously undergoes charge ordering and antiferromagnetic phase transitions below 230 Kelvin. Using resonant x-ray diffraction, we directly observe the charge ordering propagation vector in AgNiO2. Our findings elucidate that the charge ordering lifts the orbital degeneracy of the Ni2+ ions below the transition temperature, thereby resolving geometric frustration and permitting antiferromagnetic order to develop.

Input: The formation of terrestrial and habitable planets in binary and multi-star systems represents a unique and intriguing aspect of planetary science. This article investigates the factors that influence planet formation in such systems, considering the dynamical interactions and gravitational perturbations that arise from multiple stellar companions. We review recent observations and theoretical models to assess the prevalence and stability of planetary systems in binary and multi-star configurations. The presence of additional stellar companions can alter the planet formation process through gravitational instabilities, perturbed disk structures, and changing dynamical environments. We discuss the implications of these effects on the habitability of planets, including their orbital stability, climate, and potential for hosting life. Finally, we highlight the future prospects for observational surveys and numerical simulations aimed at further understanding the formation and long-term evolution of terrestrial and habitable planets in binary and multi-star systems.

Input: The fraction of barred galaxies is 45% in our sample with 3000 galaxies.The properties of bars correlate with the properties of their host galaxies, and less and weaker bars are hosted by galaxies with higher central light concentration.The molecular gas distribution is characterized in 68 nearby galaxies, and the degree of molecular central concentration varies smoothly with Hubble type.The comparison of barred and non-barred galaxies suggests that Hubble type plays a more important role in concentrating gas into the central regions than bars.We found the offset ridges along the kpc-scale bar continue to the central spiral structure embedded in the weak oval structure.The mass concentration is estimated to be 2 X 10^8 Mo within R = 35 pc, and the star-forming region appears after 2 X 10^5 yr.Bars are larger in larger galaxies, and the bar length and galaxy size are correlated.The sample set of 166 galaxies span a wide range of galactic properties.The bars in S0s galaxies are weaker than those in later-type galaxies.Neither the bar strength nor bar length correlate with the local galaxy density.Galaxies with higher central light concentration host less and weaker bars.

Input: In this study, we investigate the processes of $e^+ e^-\to K^+ K^- \pi^+\pi^-\gamma$, $K^+ K^- \pi^0\pi^0\gamma$, and $K^+ K^-  K^+ K^-\gamma$, where a hard photon is radiated from the initial state. Utilizing a dataset of 232 fb$^{-1}$ collected at the BaBar experiment, we select approximately 20000, 4300, and 5500 fully reconstructed events for the respective final states. The effective center-of-mass energy of the $e^+ e^-$ system is determined by the invariant mass of the hadronic final state, enabling a comparison of the obtained cross sections with direct measurements performed exclusively for the $K^+ K^- \pi^+\pi^-$ channel. By analyzing the event structures, we identify contributions from various intermediate states and determine their respective cross sections whenever possible. Notably, we isolate the contribution from $e^+e^-\to\omega(782)\pi^+\pi^-$ and examine the resonances $\omega(1420)$ and $\omega(1650)$. Furthermore, we observe the presence of the $J/\psi$ particle in all the examined final states and several intermediate states within the charmonium region. We also measure the corresponding branching fractions associated with these observations. These results provide valuable insights into the dynamics of these processes and expand our knowledge of the involved particles' properties.

Input: This is the eight sentences of the title of the article. Abstract: We have studied the optical variability of galaxies and X-ray sources in the field of great observation stations (Goods-South). On the baseline of about one year, using deep optical imaging from the Hubble Space Telescope, we searched the brightness changes between the infrared sources with 3.6 to 8 microns from 3.6 to 8 microns and the known X -ray source. A total of 38 power -based galaxies and 58 X -ray sources are changing under the significant of> 5σ. For some of the most extreme cases, the range of variability range ranges from several to 50 %. Preliminary color analysis found that the variable source is more blue than the stable comparison sample. As a result, it provides insight into the physical mechanism of the active galaxy nucleus covering and non -obstacles. Further research on this unique variable source directory will help represent the mutation performance between electromagnetic spectrum.
