Summary: Observational evidence suggests that coronal jets can interact with prominences, leading to large-amplitude oscillations in some areas. 2.5D MHD numerical experiments are conducted to study this process. The jets generate multiple reconnection processes, resulting in the emission of perturbations and plasma jets which cause oscillations in the prominence. The observed oscillation amplitudes and periods generally match the simulations in two different height scenarios above the parasitic bipolar region.

Summary: This study presents a dual-component model to analyze the quantum dynamics of relativistic particles and investigates the modulation of matter waves' phase and amplitude caused by Heisenberg's uncertainty principle. Simulation results indicate that mass oscillations are more prominent for light-weighted elementary particles. An interference experiment using neutrinos and electrons is proposed to test the predicted behaviors.

Summary: In this paper, the authors use OpenFOAM, an open-source computational fluid dynamics software, to investigate the fluctuation phenomenon of water inside a one-dimensional enclosed harbor basin caused by falling wedges with various horizontal positions, initial velocities, and masses. They find that the falling wedges can directly trigger harbor resonance and analyze the influences of horizontal position, initial velocity, and mass on the response amplitudes of the lowest three resonant modes. The results show that the falling position and initial velocity affect the response amplitudes of the resonant modes, and the response amplitudes of all modes increase with the mass of the wedge.

Summary: Noting the limitations of classical asymptotic methods in describing the resonance peak of a nonlinear oscillator, a new approach is proposed. The differences between the multiple time scale method and numerical simulations are demonstrated using the Duffing equation as a reference. The proposed approach involves solving the zero-order problem nonlinearly and obtaining closed-form solutions for higher-order problems, allowing for a fully analytical approach. Practical applications of this method in periodic nonlinear oscillations are explored, along with a simple formula for determining intersections of frequency response and backbone curves.

Summary: A surprising consequence of nonlinear flavor evolution is the spontaneous breaking of the initial symmetries of the neutrino gas in a dense astrophysical environment. By considering the angular distributions of neutrinos, we explore the physics of flavor conversion and present the first example of spontaneous symmetry breaking in the context of fast flavor mixing in the nonlinear regime. Interestingly, we find that fast flavor mixing does not always occur in the angular regions with vanishing electron lepton number, and large flavor mixing can rapidly spread to all neutrino modes. These results can have significant implications for the physics of compact astrophysical objects.

Summary: This study reports the magneto-Seebeck effect, large Nernst effect, and temperature-induced Lifshitz transition in the topological semimetal YbMnSb2. Quantum oscillations were observed in the magneto-Seebeck effect, with the extraction of six frequencies and a light effective mass of F4. A large Nernst effect was also discovered around 120 K and 14 T, which was mainly attributed to the high mobility and small Fermi energy induced by the Dirac bands, and further enhanced by the temperature-induced Lifshitz transition.

Summary: The study analyzed ECoG recordings of 18 presurgical human patients and found that oscillation-based functional connectivity exhibits highly similar spatial organization across different cognitive states, primarily intrinsic in nature. Each frequency band also showed independent connectivity dynamics to support frequency-specific information exchange.

Summary: This article investigates the dynamics of a reaction-diffusion predator-prey model with schooling behavior, obtaining the existence domain and stability of the constant positive steady state, as well as the amplitude equations near the Turing unstable domain. Numerical simulations demonstrate the model's complex dynamical behaviors, providing insights into the interaction between two species.

Summary: The centers of core-collapse supernovae are extremely dense environments where a first-order phase transition from ordinary nuclear matter to the quark-gluon plasma may occur. This transition can drive a supernova explosion and leave a distinct signature in the neutrino signal. The study shows that the observation of this signature at large-scale neutrino detectors can impose competitive constraints on neutrino masses and aid in localizing the supernova through triangulation. The triangulation method can significantly improve the angular uncertainty of supernova localization compared to the often considered rise time of the neutronization burst in literature.

Summary: Biophysical models of large-scale brain activity are important tools for understanding the mechanisms behind observed patterns in neuroimaging. This study introduces a parsimonious brain model that can describe fluctuations of local synchrony without reducing within-ensemble dynamics to macroscopic variables. The model reveals that functional connectivity emerges when there are high fluctuations of local and global synchrony simultaneously.

Summary: The study aimed to investigate the desiccation tolerance of the fern Polypodium virginianum and its response to sustained thermal dissipation. The results demonstrated that P. virginianum is desiccation-tolerant and utilizes sustained forms of zexanthin-dependent thermal dissipation in response to desiccation and low temperatures.

Summary: Oscillatory Hes1 expression activates cell proliferation by down-regulating the expression of p21, while sustained Hes1 overexpression inhibits cell proliferation by up-regulating p21 expression indirectly. This suggests that Hes1 differentially controls neural stem cell proliferation depending on its expression dynamics.
