Integration of Nodal and BMP Signaling by Mutual Signaling Effector Antagonism
Cell Reports, 2020 Summary: Opposing sources of bone morphogenetic protein (BMP) and Nodal signaling molecules are sufficient to induce the formation of a full axis in zebrafish embryos.

Development of Rotaxanes as E-Field-Sensitive Superstructures in Plasmonic Nano-Antennas
Organic Materials, 2022 We present the concept of electrostatic field-driven supramolecular translation within electrically connected plasmonic nano-antennas. The antenna serves as an anchoring point for the mechanically interlocked molecules, as an electrode for the ...

On Algebraic Multi-Ring Spaces [PDF]
, 2005 A Smarandache multi-space is a union of n spaces with some additional conditions hold. Combining these Smarandache multi-spaces with rings in classical ring theory, the conception of multi-ring spaces is introduced and some characteristics of multi-ring

Stiffness Considerations for a MEMS-Based Weighing Cell
Sensors, 2023 In this paper, a miniaturized weighing cell that is based on a micro-electro-mechanical-system (MEMS) is discussed. The MEMS-based weighing cell is inspired by macroscopic electromagnetic force compensation (EMFC) weighing cells and one of the crucial ...

A remark on group rings of periodic groups [PDF]
International Journal of Group Theory, 2016 A positive solution of the problem of the existence of nontrivial pairs of zero-divisors in group rings of free Burnside groups of sufficiently large odd periods $n>10^{10}$ obtained previously by S. V. Ivanov and R. Mikhailov extended to all odd periods

Localized direct material removal and deposition by nanoscale field emission scanning probes
Micro and Nano Engineering, 2022 The manufactory of advanced micro- and nanoscale devices relies on capable patterning strategies. Focused electron beams, as for instance implemented since long in electron beam lithography and electron beam induced deposition, are in this regard key ...
