Magnon-Assisted Magnetization Reversal of Ni81Fe19 Nanostripes on Y3Fe5O12 with Different Interfaces

Dirk Grundler, Andrea Mucchietto, Korbinian Baumgärtl

Magnetic bit writing by short-wave magnons without conversion to the electrical domain is expected to be a game-changer for in-memory computing architectures. Recently, the reversal of nanomagnets by propagating magnons was demonstrated. However, experimen ...

Programming of Multicellular Patterning with Mechano-Chemically Microstructured Cell Niches

Pierre Osteil

Multicellular patterning of stem-cell-derived tissue models is commonly achieved via self-organizing activities triggered by exogenous morphogenetic stimuli. However, such tissue models are prone to stochastic behavior, limiting the reproducibility of cell ...

Preparation of Single-Somite Explants from Zebrafish Embryos

Andrew Charles Oates, Sundar Ram Naganathan

The body axis of vertebrate embryos is periodically subdivided into 3D multicellular units called somites. While genetic oscillations and molecular prepatterns determine the initial length-scale of somites, mechanical processes have been implicated in sett ...

Reaction wavefront theory of notochord segment patterning

Andrew Charles Oates

The vertebrate axis is segmented into repetitive structures, the vertebrae. In fish, these segmented structures are thought to form from the paraxial mesoderm and the adjacent notochord. Recent work revealed an autonomous patterning mechanism in the zebraf ...

Hunting for the wavefront: investigation of somite boundary positioning in zebrafish

Arianne Bercowsky Rama

Somitogenesis is the rhythmic and sequential formation of somites, which are tissue blocks that give rise to segmented adult body structures including the vertebrae and associated muscle. Somite formation is controlled by the segmentation clock, a populati ...

Diiron Complexes with a Bridging Functionalized Allylidene Ligand: Synthesis, Structural Aspects, and Cytotoxicity

Paul Joseph Dyson, Lucinda Kate Batchelor, Silvia Schoch

Regio- and stereoselective nucleophilic attack of cyanide (from NBu4CN) to cationic diiron vinyliminium compounds [Fe2Cp2(CO)(mu-CO){mu-eta(1):eta(3)-C-(R')C(R '')-CNMe2}]CF3SO3 ([1a-f]CF3SO3) affords the nitrile-aminoallylidene derivatives 2a-f in good to ...

Dielectrophoresis‐assisted creation of cell aggregates under flow conditions using planar electrodes

Philippe Renaud, Harald Van Lintel, Jonathan Bastien Cottet, Soufian Lasli

We present a microfluidic platform allowing dielectrophoresis-assisted formation of cell aggregates of controlled size and composition under flow conditions. When specific ex- perimental conditions are met, negative dielectrophoresis allows efficient conce ...

Transient current technique for charged traps detection in silicon bonded interfaces

Jean-Michel Sallese, Didier Bouvet, Alessandro Mapelli

Wafer bonding is an established technology for the manufacturing of silicon-on-insulator (SOI) substrates, microelectromechanical systems (MEMS) and microfluidic devices. Low temperature direct bonding techniques can be of particular interest for the fabri ...

Embryonic lateral inhibition as optical modes: An analytical framework for mesoscopic pattern formation

Andrew Charles Oates, Jose Negrete Jr

Cellular checkerboard patterns are observed at many stages of embryonic development. We study an analytically tractable model for lateral inhibition and show that the steady states are analogous to optical phonons at the Gamma point, which have the wave nu ...

Aurora A depletion reveals centrosome-independent polarization mechanism in Caenorhabditis elegans

Pierre Gönczy, Coralie Busso, Kerstin Klinkert Fabbri, Lukas von Tobel, Christian Gentili, Marie Juliette Ségolène Pierron, Sarah Herrman

How living systems break symmetry in an organized manner is a fundamental question in biology. In wild-type Caenorhabditis elegans zygotes, symmetry breaking during anterior-posterior axis specification is guided by centrosomes, resulting in anterior-direc ...
