Summary: The study investigates the isospin dependence of spin-orbit splitting in neutron-rich nuclei, revealing the emergence of new potential magic numbers N = 14 and N = 16 with a change in the sign of the isospin-dependent term in the coupling. The traditional magic number N = 20 may disappear while N = 28 is expected to be destroyed. Additionally, the shells N = 50 and 82 may persist in the single particle scheme, and significant energy gaps are observed at N = 32 and 34 in neutron-rich calcium isotopes.

Summary: Tracer dynamics in the symmetric exclusion process (SEP) is a paradigmatic model of anomalous diffusion, where hard-core particles diffuse on a one-dimensional lattice. The equilibrium situation has been extensively studied, but the case of a driven tracer in confined crowded environments remains largely unexplored. Here, we present a general hydrodynamic framework to determine the first cumulants of the bath-tracer correlations and tracer's position in function of the driving force, up to quadratic order. This provides the first determination of the bias dependence of the variance of a driven tracer in the SEP for an arbitrary density, and the framework can be applied to more general configurations of a driven tracer in interaction with obstacles in one dimension.

Summary: Mean-field treatment (MFT) is commonly used for approximating the dynamics of quantum optics systems. However, neglecting quantum correlations between modes can lead to unexpected quantum effects. This study presents a theoretical framework based on perturbation theory and MFT to capture these effects and predicts the form and relationship of nonlinear dissipation, parasitic Hamiltonian, and nonlinear coupling rate. The framework is applied to quantum frequency conversion and shows excellent agreement with numerical simulations, revealing the neglected quantum effects by MFT and providing a more precise framework for nonlinear and quantum optics.

Summary: This article discusses the dynamical phase transition in Vicsek systems and investigates their chaotic behavior by computing the largest Lyapunov exponent (LLE). The authors find a chaotic regime for the collective behavior of the self-propelled particles (SPPs) based on the LLE and observe a significant change in the dependence of LLE on applied noise near the known transition points of the Vicsek model.

Summary: This study systematically compares the magnetic form factors of odd-A nuclei calculated with relativistic and non-relativistic models. The results show that both models can describe the magnetic form factors in spherical and deformed cases, and the discrepancies reflect the differences in the descriptions of the single-particle orbital between the two models.

Summary: Tuned mass dampers (TMDs) are control devices used for energy dissipation in civil structures, and their effectiveness is influenced by the duration of dynamic excitation and detuning effect. This study optimized the parameters of three different TMD configurations using the particle swarm algorithm and evaluated their performance on single-degree-of-freedom structures under different ground motions. It was found that the configuration with two TMDs in series tuned to a frequency of 50% of the fundamental frequency of the healthy structure achieved the highest effectiveness when the ductility demand is greater than 5.

Summary: Extracellular vesicles (EVs) are membrane vesicles enclosed by lipid membranes found in various body fluids, and they play a significant role in intercellular communication due to their diverse biomolecular composition. However, EVs exhibit high heterogeneity in terms of physical properties and biomolecular composition, necessitating the study of single-cell and single-particle EV analysis for precise analysis and functional evaluation. Microfluidic platforms integrated with cell manipulation, EV enrichment, and sensitive nucleic acid and protein detection offer the possibility of studying single-cell EVs. This review summarizes the current status of single-cell EV and single EV particle studies using microfluidic platforms and advanced detection tools, while also discussing the importance of single-cell EV heterogeneity and future developments.

Summary: This study investigates the collective behaviors of oil droplets floating on a surfactant solution in a narrow circular channel, both experimentally and numerically. A mathematical model is introduced to explain the transient oscillations and cluster formation of the droplets, showing successful reproduction of these experimental findings. The long-range interaction due to the global concentration profile of the solution is argued to be sufficient for the cluster formation.

Summary: In this study, we employed macroscopic fluctuation theory to examine the long-term statistics of a tracer's position in diffusive single-file systems under dense and dilute limits. Our analysis focuses on the large deviation functions associated with an initial step density profile under fluctuating (annealed) and fixed (quenched) initial conditions. The obtained hydrodynamic results are applicable to general single-file systems and agree with recent exact results obtained through microscopic solutions for specific model systems.

Summary: The study reveals that in active systems with topological interactions, spatial heterogeneities can maintain long-range order and enhance the emergence of traveling bands. Topological flocking models in heterogeneous environments exhibit features similar to metric models, with spatial heterogeneities inducing an effective density-order coupling that facilitates the emergence of traveling bands.

Summary: Study of the proton-rich T-z = -1 nucleus Kr-70 through inelastic scattering reveals a deviation in the electromagnetic matrix elements compared to other isotopes Br-70 and Se-70, suggesting a violation of isospin symmetry at this level not previously observed. Current nuclear structure theories are unable to quantitatively explain this anomaly, possibly indicating a shape change between Kr-70 and Se-70 contrary to model predictions.

Summary: We propose an efficient mechanism for preselecting the number of intrinsic many-body states used in the generation of many-body wave functions within the generator coordinate method (GCM). This method, based on the proper definition of a natural basis of orthonormal states, eliminates the need for evaluating the nondiagonal Hamiltonian kernels for selection and helps reduce numerical instabilities. We analyze the performance of this method in detail for the ground state and 0+ excited states of selected nuclei calculated using the Gogny energy density functional.

Summary: This article presents the first realistic results of a novel multi-reference perturbation theory (PGCM-PT) that can accurately describe the ground and low-lying excited states of complex nuclei within a symmetry-conserving scheme. The study demonstrates that PGCM-PT(2) can reproduce the exact binding energies of closed and open-shell nuclei with high accuracy and can capture essential corrections to low-lying excitation energies by including dynamical correlations.
