The patterning of many developing tissues is organized by morphogens. Genetic and environmental perturbations of gene expression, protein synthesis and ligand binding are among the sources of unreliability that limit the accuracy and precision of morphogen-mediated patterning. While it has been found that the robustness of morphogen gradients to the perturbation of morphogen synthesis can be en...

Plants use cell-surface-resident receptor-like kinases (RLKs) to sense diverse extrinsic and intrinsic cues and elicit distinct biological responses. In Arabidopsis, ERECTA family RLKs recognize EPIDERMAL PATTERNING FACTORS (EPFs) to specify stomatal patterning. However, little is known about the molecular link between ERECTA activation and intracellular signaling. We report here that the SOMAT...

Development of the musculoskeletal system requires precise integration of muscles, tendons and bones. The molecular mechanisms involved in the differentiation of each of these tissues have been the focus of significant research; however, much less is known about how these tissues are integrated into a functional unit appropriate for each body position and role. Previous reports have demonstrate...

Background: Metal-containing resists entered the mainstream semiconductor industry process flow to mitigate low absorbance of extreme ultraviolet (EUV) radiation by thin films organic that lead poor sensitivity and their inability handle rigors development etching conditions. Aim: The long rich history using metal-containing in electron beam lithography can offer interesting lessons, pointers, ...

The Journal of Micro/Nanopatterning, Materials, and Metrology (JM3) publishes peer-reviewed papers on the core enabling technologies that address patterning needs electronics industry.

PURPOSE Pediatric uroflowmetry curve interpretation is incompletely standardized. Thus, we propose new, objective patterning. MATERIALS AND METHODS Uroflowmetry curves were obtained in 100 children presenting with daytime incontinence or enuresis. Each curve was compared with a standard curve generated from a published nomogram and a new patterning method was formulated. Staccato and interrup...

Patterning substrates with biological reagents is a critical component of biosensor development. Many applications require multi-analyte patterning capabilities, with a need to deposit several species reproducibly with a high degree of precision. We demonstrate a piezoelectric inkjet printing system that is capable of creating sub-millimeter (down to 150microm) patterns of aqueous and nonaqueou...

Bone morphogenetic protein (BMP) signaling is broadly implicated in dorsoventral (DV) patterning of bilaterally symmetric animals [1-3], and its role in axial patterning apparently predates the birth of Bilateria [4-7]. In fly and vertebrate embryos, BMPs and their antagonists (primarily Sog/chordin) diffuse and interact to generate signaling gradients that pattern fields of cells [8-10]. Work ...
