Summary: This paper introduces a class of partially coherent sources that can produce beams with radially quasi-periodic and azimuthally fully periodic intensity profiles. The physical properties of the source, as well as the propagation of the intensity distribution and the complex degree of spatial coherence of the resulting beams, are investigated and explained. The results show that the shape and symmetry of the intensity, as well as the degree of spatial coherence, can be adjusted and modulated by the parameters related to the beam source. Moreover, the periodic changes in intensity are caused by the phase discontinuity. The findings provide a method for synthesizing fields with peculiar periodic intensity distributions in polar coordinates.

Summary: Investigating the burning behavior of pool fires is crucial for enhancing fire safety in energy utilization. This study explores the influence of a plate obstacle on pool fires and finds that the presence of a plate obstacle above the burner significantly affects the burning behavior, leading to rapid fire development and higher burning rates. Heat transfer analysis and correlation analysis reveal the relationship between plate obstacle characteristics and mean radiation heat flux.

Summary: The study investigated the characterization and kinetics of CO2 absorption in potassium carbonate (K2CO3) solution promoted by diethylenetriamine (DETA). It was found that the addition of small amounts of DETA resulted in a significant enhancement in CO2 absorption rate, with a reaction order of 1.6 and an activation energy of 35.6 kJ mol(-1). DETA showed better performance compared to other promoters.

Summary: This study investigates the dynamic behavior of premixed hydrogen-air deflagration flame propagation in a closed tube using the Large Eddy Simulation technique. By comparing four different types of turbulent flame wrinkling models, the dynamic wrinkling model is found to have a high level of accuracy in predicting flame behavior. The numerical results show five forms of flame evolution and the influence of obstacle arrangements on flame propagation speed and deflagration overpressure. The flame propagation process is mainly influenced by the coupling of Rayleigh-Taylor and Kelvin-Helmholtz instability mechanisms.

Summary: This paper explores various synthesis techniques to optimize amplitude and phase excitations of periodic linear arrays for generating flat-top beams, highlighting the importance of design parameters in determining the optimal tapering. Linear programming techniques are employed to derive relations between these parameters, ensuring the optimality of solutions, which are then utilized in design examples.

Summary: Phononic crystals (PnCs) have great potential for dissipation engineering and phonon propagation manipulation, with graphene being a promising material for nanoelectromechanical resonators. A nanoelectromechanical periodic array can be achieved by anchoring a graphene membrane to a vertical array of nanopillars, demonstrating a continuous frequency spectrum for resonance modes.

Summary: The adsorption and storage properties of H2S gas by pentagonal B2C nanosheet (penta-B2C) were investigated using periodic density functional theory. The pristine penta-B2C nanosheet can adsorb up to eight H2S molecules with a capture capacity of 50.28 wt%. The band gap of the penta-B2C nanosheet is reduced by 13%-25% after H2S adsorption. Molecular dynamics calculations confirm the thermal stability of the penta-B2C nanosheet and the 8H(2)S/penta-B2C complex at 300 K. Based on the analysis, penta-B2C nanosheet can be considered as a promising substrate for efficient H2S capture and storage.

Summary: This study investigates turbulent flow over a wall-mounted cube in a spatially evolving turbulent boundary layer using wall-resolved large eddy simulations. The research focuses on the dependence of turbulence wake characteristics on the ratio of cube height to boundary-layer thickness, and analyzes vortical structures, separation and reattachment lengths, as well as turbulent kinetic energy budget variations.

Summary: The objective of this study is to investigate the propagation of a premixed flame through obstacles and the interactions between flame and obstacles. Different premixed flame models were evaluated using OpenFoam, all of which are based on progress variable evolution and consider the increase in flame speed due to turbulence effects.

Summary: This retrospective study reanalyzed 1641 Array-CGH performed between 2010 and 2017 and found that 15.7% of CNVs were initially reported as of uncertain significance. After reinterpretation, 40.9% of patients had changes in CNV classification, and 4.6% had VUS reclassified as likely pathogenic. The study highlights the importance of CNV reinterpretation for genetic counseling.

Summary: The effects of ground slope and obstacle conditions on the lateral overturning/backward rollover of a tractor with an implement were analyzed through dynamic simulation. The study found that the tractor experiences backward rollover at low ground slopes and lateral overturning at specific slopes or higher. The presence of an implement decreases the driving safety of the tractor due to changes in the center of gravity. The height and shape of obstacles also impact the safety.
