Summary: The study investigates the spatial and temporal evolution of fluid flow and resulting fracture geometry in a hydraulic fracture driven by a non-Newtonian shear-thinning fluid. The analysis demonstrates that rheological properties of fluids significantly impact the hydraulic fracturing process.

Summary: Periodically-driven systems are common in the fields of science and technology, and understanding the constraints that govern the dynamics of such systems is of great interest. This study derives a set of constraints for each number of cycles in quantum dynamics and demonstrates experimentally the relevance of these constraints for modern quantum systems. Furthermore, it shows the potential of using these constraints to detect the effect of the environment in quantum circuits that cannot be simulated classically.

Summary: By studying low-lying excitations at filling factor nu = n + 1/3 with realistic interactions, it is found that they can be understood as quantum fluids with Gaffnian quasiholes, instead of Laughlin quasiparticles. Near the experimentally observed nematic FQH phase in higher Landau levels, quasiholes become weakly bound and exhibit rich dynamical properties. It is predicted that a finite temperature phase transition of Laughlin quasiholes can occur even when the Laughlin ground state remains incompressible, providing relevant experimental conditions for potential observations.

Summary: The disorder-order transitions of layering and intralayer structural orders in three-dimensional Yukawa liquids under enhanced confinement effect were investigated numerically. It was found that with decreasing normal distance to the confinement boundary, the emergence of small clusters of layering order (LOS) is followed by the formation of large percolating LOS clusters spanning the system. The disorder-order transition of intraslab structural ordering exhibits a similar generic behavior as layering. The correlation between local layering order and local intralayer structural order gradually increases as the percolating transition slab is approached.

Summary: A vibrational model for heat conduction in liquids with soft pairwise interactions is used to estimate the thermal conductivity coefficient of strongly coupled Yukawa fluids, showing reasonable agreement with numerical simulation data. The results are relevant for studying strongly coupled plasmas and complex plasma fluids under the context of Yukawa interaction potential.

Summary: Wormholes require negative energy and exotic matter as a source. Casimir energy, being negative, has long been speculated as a good candidate for this. Recently, Garattini found a full solution for 3+1 dimensions, confirming that Casimir energy can be a source for traversable wormholes. Further research has explored the effects of Yukawa-type terms on wormhole shape functions and obtained promising results.

Summary: Recently, it has been conjectured that bridge functions in R-simple liquids remain nearly invariant along phase diagram lines of constant excess entropy. However, testing this hypothesis using the bridge functions of Yukawa systems showed that while they exhibit a high degree of isomorph invariance, deviations from isomorphism exceed overall uncertainties.

Summary: This study investigates the influence of substituents on the triplet potential energy surface and explores the triplet potential energy surfaces of bimetallic Pt(ii) complexes using density functional theory. The results show that the composition of the triplet potential energy surface can be determined by the adiabatic triplet energy, and the properties of the triplet potential energy surface can be tuned by adding various substituents.

Summary: A new and simple correlation based on the corresponding-states principle is proposed for predicting the relation of the vaporization enthalpy with the temperature for saturated silanes. The model shows good accuracy and predictive power when compared with DIPPR data and data for other silanes not included in DIPPR, outperforming previously published corresponding-states correlations.

Summary: This study examines the impact of lateral entrainment on pollutant dispersion within urban street canyons and proposes three optimization strategies to improve air quality. Results show that lateral entrainment can significantly reduce pollutant concentrations in high-rise canyons. The three strategies can effectively enhance lateral entrainment, leading to a substantial reduction in pollutant concentrations and personal intake fractions of residents.

Summary: This study reports the experimental behavior of the UHMWPE/AISI 316L tribopair, indicating that the coefficient of friction is higher for the micro-textured surface compared to the smooth surface. Experimental data shows that the coefficient of friction has an inverse relationship with the load, and a direct relationship with the entrainment and sliding-to-rolling ratio.

Summary: This article discusses the possibility of stabilizing non-Abelian topological orders in the fractional quantum Hall effect (FQHE) in the second Landau level (SLL). A parton sequence is proposed to describe the observed fractions in the SLL. By studying the first member of this sequence at 4/11, which has not been experimentally observed yet, we find that it might be a viable non-Abelian state and make predictions for experimentally measurable properties that can distinguish it from other topological orders.

Summary: To enhance the flow and heat transfer efficiency in micro/nanofluidic devices, it is necessary to eliminate thermal indulgence. The rapid transport and mixing of metallic colloidal suspensions at the nanoscale are crucial. This study investigates the role of a trimetallic nanofluid in a heated micropump, utilizing biomimetic motile cilia and external fields. The trimetallic nanofluid exhibits higher heat transfer efficiency, and the involvement of electroosmosis and thermal radiated contribute to reducing heat losses.

Summary: In this work, a mathematical function based on coherent and incoherent states of a chain of spatially distributed oscillators is proposed to characterize chimeras. The function analyzes the spatial distance between the nearest neighbors in a chain of coupled oscillators. Spatial correlation is also studied to explore the correspondence between correlation decay and chimera state formation. A Kuramoto-like model in a long-range coupling network is utilized for these studies.
