Summary: Gregor Mendel is recognized as the founder of genetics, with his theory encompassing principles such as segregation and independent assortment, as well as aspects like fertilization and hybridization. However, due to the loss of most original documentation, there have been misconceptions and speculations about his history and achievements.

Summary: The study found that mythical elements in films released in mainland China do not have a significant impact on box office revenues and film ratings, and the general public in modern society lacks sensitivity to mythical elements in films.

Summary: Heat exchangers are versatile thermal devices whose structure and performance evaluation vary with application scope. Due to high costs, researchers prefer using CFD-based computational methods. This study found that the SST-type k-omega model performs the best, while the realizable-type k-epsilon model performs the worst.

Summary: This study reveals important insights into the role of symbols in human reasoning through the process of developing the symbolic universe. Symbols serve as explanatory axes for understanding global realities. Myths and symbols can be found in all cultures, with some of the most powerful occurring in popular culture due to their immediate social impact.

Summary: We present simple renormalizable extensions of the standard model where baryon number violating processes have Delta B = +/-Delta L = -2. These models involve additional scalars, such as a color singlet and a colored sextet. Experimental observations show that the scalars cannot be much heavier than a few tera-electron-volts, and these models are constrained by LHC physics, LEP physics, and flavor physics.

Summary: Due to the helicity suppression effect, the rare decay channel Bs -> e+e- within the Standard Model has a low decay probability. Observing this channel in current or forthcoming experiments would provide evidence of physics beyond the Standard Model. In this study, a new physics scenario is proposed in which the branching fraction B over line r(Bs -> e+e-) is enhanced to saturate current experimental bounds. The study explores the two-Higgs-doublet model with a pseudoscalar coupling to unsuppressed electrons and establishes correlations with other lepton flavor-violating decays.

Summary: Computational fluid dynamics (CFD) simulations were used to investigate the scale effect on the hydrodynamic performance of a single-blade cycloidal propeller. The study determined the hydrodynamic coefficients using the Shear Stress Transport (SST) turbulence model and a reasonable numerical scheme. The results showed that the scale effect of the cycloidal propeller differs from conventional screw propellers, leading to the invalidation of the scale effect formula recommended by the International Towing Tank Conference (ITTC). A new formula based on extensive numerical simulations was proposed.

Summary: The study delves into the geometry and number theory underlying the butterfly graphs of the Harper and generalized Harper models of Bloch electrons in a magnetic field, revealing the root of the fractal spectrum's number theoretical characteristics and the close relationship between the Farey tree and the Wannier diagram. Furthermore, it explains how some features of the energy spectrum in the butterfly graph can be attributed to a simple rule of minimal violation of mirror symmetry, and how in a generalized Harper model, the number theoretical framework prevails to create different species of butterflies through a rearrangement of the Farey-Wannier hierarchical lattice.

Summary: This paper argues that hereditarian research on race differences in intelligence has not been subject to a long and effective taboo, as there have been extensive publications, citations, and discussions of such work since 1969. It also points out that claims of current suppression of hereditarians in the media, threats, denouncements, and job loss are exaggerated and distorted. Additionally, it criticizes accusations that negative reception of research asserting average Black inferiority is due to ideological control over the academy by environmentalists, leftists, Marxists, or thugs as unwarranted character assassinations.

Summary: A numerical investigation was conducted on circular cylinders with different angular orientations, showing that the interaction between the upwind and downwind cylinders led to more complex flow patterns. It was found that both the drag and lift coefficients of the cylinders increased with changes in angular position, as did the shedding frequency.

Summary: This paper provides a complete answer to the question raised by Dimca and Greuel regarding the quotient of the Milnor and Tjurina numbers of a plane curve singularity. It places this question within a general framework of studying the difference between the Milnor and Tjurina numbers for isolated complete intersection singularities, highlighting its connection with other problems in singularity theory.

Summary: We demonstrate the phase transition between the trivial and the topological semimetal phases in a non-Hermitian two-leg ladder model. By studying an equivalent model with chiral symmetry, we show that the system exhibits a gapless topological semimetal phase induced by four exceptional points. Furthermore, we find that the transmission behaviors within the trivial and topological semimetal phases can be dynamically characterized by the propagation speed of the evolved initial state.

Summary: In this paper, the authors prove that the chromatic number x(G2) of the square graph of a maximal planar graph with diameter two and maximum degree &UDelta; satisfies certain conditions and all the bounds are tight. This confirms Wegner's conjecture for maximal planar graphs with diameter two.
