We demonstrate passive capillary patterning of channel walls with a liquid in situ. Patterning is performed using a novel 3D capillary valve system combining three standard capillary stop valves. A range of different patterns is demonstrated in three channel walls. Capillary patterning was designed for precise in situ patterning of phase-change materials (e.g. UV curable hydrogels, gels, resins...

The realization that nanostructured graphene featuring nanoscale width can confine electrons to open its bandgap has aroused scientists’ attention the regulation of structures, where concept patterns emerged. Exploring various effective methods for creating led birth a new field termed patterning, which evolved into most vigorous and intriguing branch research during past decade. efforts in thi...

The ability to discover a regularity among an ordered set of units, termed patterning, is a crucial cognitive ability that precedes pre-algebraic mathematics skills and possibly reading. However, there is limited research on the cognitive underpinnings of patterning. There is some suggestion that there is a relation between cognitive flexibility, which is the ability to switch attention between...

Hippocampal function is important in the acquisition of negative patterning but not of simple discrimination. This study examined rat hippocampal theta activity during the acquisition stages (early, middle, and late) of the negative patterning task (A+, B+, AB-). The results showed that hippocampal theta activity began to decline transiently (for 500 ms after non-reinforced stimulus presentatio...

Patterning in Arabidopsis root development is coordinated via a localized auxin concentration maximum in the root tip, requiring the regulated expression of specific genes. However, little is known about how hormone and gene expression patterning is generated. Using a variety of experimental data, we develop a spatiotemporal hormonal crosstalk model that describes the integrated action of auxin...

Androgenetic alopecia is a common form of pattern hair loss, characterized by miniaturized follicles (HFs) at the front and parietal scalp, while hairs on occipital scalp are preserved. Moreover, different sites human body exhibit distinct types patterns HFs. Understanding molecular basis this heterogeneity will help to design targeted treatment strategies. The Wnt signalling pathway its Dickko...

INTRODUCTION A bone morphogenetic protein (BMP) signaling gradient patterns cells along the embryonic dorsoventral (DV) axis (Little and Mullins, 2006). BMP signaling is abrogated dorsally by the secreted BMP antagonists Chordin, Noggin and Follistatin to generate low BMP signaling levels that allow neurectodermal tissues to develop. These and additional extracellular modulators generate the mo...

Patterning is a crucial fabrication step for successfully applying two-dimensional materials in electronic and optoelectronic devices. It can realize miniaturization help explore new physical phenomena of 2D materials. However, the manufacturing process inevitably introduces defects, which require harsh conditions to recover. Here, we propose sputtering-lithography-annealing (SLA) strategy patt...

Although spatial patterning during embryonic development is well characterized, a corresponding framework for temporal patterning has not been established. In this issue, Zhu et al. (2006) identify the Chinmo protein as conferring temporal identity on the neural progeny of Drosophila neuroblasts, revealing appealing parallels with spatial patterning.
