Summary: This study investigated the value of 4D flow MRI in measuring mitral filling and its correlation with TTE and 2D flow MRI. The results showed good agreement between 4D flow MRI and the reference methods in measuring flow rates and E/A ratios. The measurements using 4D flow MRI were reproducible and correlated with age and LV remodeling.

Summary: The study implemented sophisticated color M-mode analysis in infants, showing feasible comprehensive analysis of transmitral color M-mode data and significant progression in left ventricular diastolic function maturation during infancy. The findings of this study provide a foundation for future research to explore alterations in early diastolic filling in congenital heart disease.

Summary: The hydraulic force generated by blood moving the atrioventricular plane is a novel mechanism of diastolic function, where the net hydraulic force aids in cardiac filling. Pathological remodeling may impact this mechanism negatively, exacerbating diastolic dysfunction in heart failure with preserved ejection fraction, while it may have a favorable effect in patients with dilated ventricles, such as heart failure with reduced ejection fraction.

Summary: The one-dimensional antiferromagnetic correlated electron system described by the unusual t-U-J model with alternating on-site interactions at odd and even sites exhibits insulating behavior due to unequal on-site repulsion. Depending on the value of Ue+Uo in relation to 2J, the system can be in a spin-gapped phase with charge-density-wave instability or a spin-gapless phase with coexisting CDW and SDW instabilities.

Summary: In this study, the extended Hubbard model on a two-dimensional square lattice at half-filling is investigated using the strong coupling diagram technique. The first-order phase transition in the charge subsystem is found to occur at v = v(c) greater than or similar to U/4. The transition is characterized by an abrupt sign change in the zero-frequency charge susceptibility at the corner of the Brillouin zone. The alternating deviations of electron occupations from the mean value on neighboring sites have short-range order due to fluctuations.

Summary: The filling medium used in rock blasting greatly impacts the blasting result. This study investigated the effect of different filling media (gas, solid, liquid, and solid-liquid mixed) on the spatial distribution and shape of explosion cracks in rock. The fractal dimension and degree of damage of the explosion cracks were determined using fractal theory. The density of explosion cracks was highest when a solid-liquid state was used as the filling medium, while it was lowest when air was used.

Summary: Wave energy is a promising renewable energy source with large resources, offering more stability and predictability than wind and solar energy. Despite the lack of commercially viable wave energy converters, it is important to assess the economic potential and costs analysis for early development stages to identify possible bottlenecks or improvements.

Summary: The article introduces a reliability analysis approach for wave energy converter (WEC) development based on reliability block diagram (RBD) modeling, applied to a case study involving a hydraulic wave surge converter. It discusses data sources and considerations, presenting examples of applying the RBD modeling approach in new technology development support.

Summary: Colloidal semiconductor nanoplatelets exhibit excellent optical emission properties due to their quasi-2D structures and strong in-plane Coulomb interactions. The charging of nanoplatelets with interacting fermions leads to severe Coulomb repulsions, resulting in strong electronic correlations and exchange energies. These phenomena give rise to characteristic physical effects such as deviating shell filling spectra, large addition energies for deterministic control of the number of charges, and activation of paramagnetic electron spin configuration at cryogenic temperatures.

Summary: Based on the MIKE21 SW model, wave-current coupled and uncoupled numerical models were established for the Zhoushan sea area. The influence of tidal level on wave parameters is greater than that of tidal current, but the annual average wave energy flux difference is mainly caused by tidal current. Wave-current interaction redistributes wave energy near the peak of the wave spectrum, resulting in a flatter peak. The absorbed power of wave energy converters is affected by wave-current interaction, which changes the matching between the wave energy distribution interval and the optimal conversion interval of the converters.

Summary: Intramolecular energy flow is often assumed not to hinder reactions in rate calculations, but experimental spectroscopy and computational results indicate that it actually occurs slowly. A simple model has been developed to simulate the interplay of IVR and energy transfer, revealing a phase transition that influences the controllability of reactions.
