Open AccessRevealing the three-dimensional arrangement of polar topology in nanoparticles
In the early 2000s, low dimensional ferroelectric systems were predicted to have topologically nontrivial polar structures, such as vortices or skyrmions, depending on mechanical or electrical boundary conditi...

Open AccessEmergence of a mutual-growth mechanism in networks evolved by social preference based on indirect utility
Preferential attachment is an important mechanism in the structural evolution of complex networks. However, though resources on a network propagate and have an effect beyond a direct relationship, growth by pr...

Open AccessDirect strain correlations at the single-atom level in three-dimensional core-shell interface structures
Nanomaterials with core-shell architectures are prominent examples of strain-engineered materials. The lattice mismatch between the core and shell materials can cause strong interface strain, which affects the...

Open AccessVisualizing inflammation with an M1 macrophage selective probe via GLUT1 as the gating target
Macrophages play crucial roles in protecting our bodies from infection and cancers. As macrophages are multi-functional immune cells, they have diverse plastic subsets, such as M1 and M2, derived from naïve M0...

Open AccessSex-linked deubiquitinase establishes uniparental transmission of chloroplast DNA
Most sexual organisms inherit organelles from one parent, commonly by excluding organelles from the smaller gametes. However, post-mating elimination of organelles derived from one gamete ensures uniparental i...
