Summary: Many emerging materials, such as ultrastable glasses, owe their properties to a gradient of enhanced mobility at the surface of glass-forming liquids. This surface mobility enhancement has reshaped our understanding of glass formers behavior, especially in polymeric glasses with a two-scale nature of glassy polymer surfaces. The emergence of a transient rubbery surface behavior in polymers with short chains is driven by superposed gradients in segmental dynamics and chain conformational statistics, leading to a breakdown in time-temperature superposition.

Summary: ZnO nanorod arrays were grown on carbon cloth using a hydrothermal method, followed by deposition of titanium nitride nanoparticles. The field emission performance of ZnO nanorods was found to depend on the thickness of the TiN coating, with ZnO/TiN240 core-shell arrays exhibiting improved properties.

Summary: This study investigates the orientation of LCLCs in a capillary bridge surrounded by air walls made of glass and line-patterned silicon hybrid cells. The optical textures of different structures of LCLCs, such as uniaxial, escaped, and non-symmetric chiral structures, are directly observed and analyzed using polarized optical microscopy. This research has significant implications for dichroic optical films, optoelectronic devices, and sensors.

Summary: Selective withdrawal is an effective and promising method to mitigate thermal pollution and environmental problems in reservoirs and downstream rivers. However, the potential effects of selective withdrawal on harmful algal blooms in reservoirs are uncertain. This study developed a hydro-ecological model to investigate how different withdrawal scenarios affect algal growth and hydrodynamic environments in Zipingpu reservoir. The results showed that surface withdrawal could efficiently inhibit algal growth and decrease algal bloom concentration in the reservoir.

Summary: This study demonstrates the rectilinear motion of individual skyrmions in temperature gradients using a temperature-related phase field model and reveals that the energy imbalance induced by temperature gradients drives the motion of skyrmions. A kinematic equation is proposed to describe the motion of skyrmions in temperature gradients.

Summary: The latitudinal gradient of increasing marine biodiversity from the poles to the tropics is a noticeable pattern, but low-latitude regions are expected to be most affected by climate change. Fossil evidence suggests that biodiversity peaks may have occurred further away from the equator in the past, possibly due to transitions between climate states.

Summary: This study proposes a model for crossover patterning, suggesting that the diffusion of HEI10 along the synaptonemal complex leads to a coarsening process that creates well-spaced crossover-promoting foci. The findings support this model and provide insight into the mechanistic basis of crossover control during meiosis.

Summary: This study presents a complete algorithm for constructing and solving a projection-based reduced order model coupled with an artificial neural network model, with the reduced model based on Galerkin projection and Proper Orthogonal Decomposition method, implemented using numerical discretization schemes in the OpenFOAM platform, and the neural network model trained with NARX architecture. The reduced order models accurately predict the behavior of incompressible flows at low Reynolds numbers, showing excellent agreement with full CFD simulations while requiring significantly fewer computational resources.

Summary: This work demonstrates the integration of multiple machine learning models with a reduced order model for modeling the flow past a stationary cylinder. The experiments show that locally interpolating models are more effective for modeling the time-varying characteristics of POD coefficients, and that the coefficients are best modeled using their own previous time values.

Summary: This study proposes a novel physics-informed neural network (PINN) method that combines automatic differentiation (AD) and numerical differentiation (ND) to improve the training efficiency and accuracy. The proposed method, called canPINN, achieves more robust and efficient training than AD-based PINNs, while improving accuracy by up to 1-2 orders of magnitude relative to ND-based PINNs. The method is demonstrated on challenging fluid dynamic problems, showing consistently high accuracy compared to conventional AD-based PINNs.
