this paper examines the transport analysis, including both heat transfer and mass transfer, in hybrid nanofluid flow containing gyrotactic microorganisms towards a curved oscillatory surface. the influence of magnetic fields is also inspected in terms of their physical characteristics. to depict the phenomena of transport, modified versions of both Fick's and Fourier's laws are used. Additionally, the characteristics of both heterogeneous and homogeneous chemical reactions are also incorporated. Utilizing a curvilinear coordinate system, the flow problem is formulated as partial differential equations(PDEs)for momentum, concentration, microorganism field, and energy. An analytical solution to the obtained flow equations is achieved utilizing the homotopy analysis method(HAm).the effects of significant flow parameters on the pressure and microorganism fields, velocity, oscillation velocity, concentration, and temperature distributions are shown via graphs. Furthermore, the variations in skin friction, mass transfer rate, heat transfer rate, and local motile number due to different involved parameters are presented in tables and are analyzed in detail. Graphical results indicate that the curves of velocity and temperature fields are enhanced as the values of the solid volume fraction variables *** is also verified that the concentration rate field decreases as the values of the homogeneous reaction strength parameter and the radius of curvature parameter increase, and it increases with the Schmidt number and the heterogeneous reaction strength *** outcomes show a favorable response of the motile number to advanced values of the Peclet number, the Schmidt number, the microorganism difference parameter, and the bio-convective Lewis number.

the formation of an embedded electron current sheet within the magnetotail plasma sheet has been poorly *** this article,we present an electron current layer detected at the edge of the magnetotail plasma *** ions were demagnetized inside the electron current layer,but the electrons were still frozen in with the magnetic field ***,this decoupling of ions and electrons gave rise to a strong Hall electric field,which could be the reason for the formation of the embedded thin current *** magnetized electrons,the absence of the nongyrotropic electron distribution,and negligible energy dissipation in the layer indicate that magnetic reconnection had not been triggered within the embedded thin current *** highly asymmetric plasma on the two sides of the current layer and low magnetic shear across it could suppress magnetic *** observations indicate that the embedded electric current layer,probably generated by the Hall electric field,even down to electron scale,is not a sufficient condition for magnetic reconnection.

the local structure and thermophysical behavior of mg-La liquid alloys were in-depth understood using deep potential molecular dynamic(DPmD) simulation driven via machine learning to promote the development of mg-La alloys. the robustness of the trained deep potential(DP) model was thoroughly evaluated through several aspects, including root-mean-square errors(RmSEs), energy and force data, and structural information comparison results;the results indicate the carefully trained DP model is reliable. the component and temperature dependence of the local structure in the mg-La liquid alloy was analyzed. the effect of mg content in the system on the first coordination shell of the atomic pairs is the same as that of temperature. the pre-peak demonstrated in the structure factor indicates the presence of a medium-range ordered structure in the mg-La liquid alloy, which is particularly pronounced in the 80at% mg system and disappears at elevated temperatures. the density, self-diffusion coefficient, and shear viscosity for the mg-La liquid alloy were predicted via DPmD simulation, the evolution patterns with mg content and temperature were subsequently discussed, and a database was established accordingly. Finally, the mixing enthalpy and elemental activity of the mg-La liquid alloy at 1200 K were reliably evaluated,which provides new guidance for related studies.
