Optoelectronic Synaptic Devices Using Molecular Telluride Phase‐Change Inks for Three‐Factor Learning

Advanced Functional Materials, EarlyView.
Optoelectronic synaptic devices based on solution‐processed molecular telluride GST‐225 phase‐change inks are demonstrated for three‐factor learning. A global optical signal broadcast through a silicon waveguide induces non‐volatile conductance updates exclusively in locally electrically flagged memristors.

An investigation into how the cell cycle and the Notch signalling pathway regulate pronephrogenesis in Xenopus laevis [PDF]

The connections between cell cycle exit and terminal differentiation remain poorly understood. Cyclin dependent Kinase Inhibitors (CKIs) provide a possible link between entry into the quiescent state and differentiation.

Regulation of the self-renewal vs. differentiation decision in the C.elegans germline [PDF]

, 2011
Adult stem cells are the basis of our reproductive potential, of tissue growth and maintenance, and of wound healing and regeneration. Ageing phenotypes such as hair loss or brittle bones in fact reflect the gradual decline of the proliferative ...

Design of a UWB Interference-Rejection LNA Based on a Q-Enhanced Notch Filter

Micromachines
A Q-enhanced notch filter for interference-rejection LNAs is proposed in this brief. The active capacitance is introduced into the notch filter to improve the quality factor by the negative resistance effect.

Optical Signature of Moiré Superlattices Formed by Twisted SrTiO3 Membranes

Advanced Functional Materials, EarlyView.
We discover optical signatures from bonded interfaces in twisted SrTiO3 moiré superlattices, including low‐frequency Raman vibrational modes and strong second‐harmonic generation, consistent with strong interlayer coupling inferred from cross‐sectional electron microscopy and ab initio calculations. ABSTRACT Moiré superlattices formed at the interfaces

Determining the role of a small GTPase, Ral, and an endocytic factor, epsin, in Drosophila Notch signaling [PDF]

, 2013
textCell-cell communication events are crucial to determine the fate of each cell during development. Notch signaling is involved in many different contexts in determining cell fate by mediating cell-cell communication.

Identification of epidermal Pdx1 expression discloses different roles of Notch1 and Notch2 in murine KrasG12D-induced skin carcinogenesis in vivo [PDF]

, 2010
Background The Ras and Notch signaling pathways are frequently activated during development to control many diverse cellular processes and are often dysregulated during tumorigenesis.

Strong Lead‐Free Bioinspired Piezoceramics for Durable Energy Transducers

Advanced Functional Materials, EarlyView.
We fabricated brick‐and‐mortar lead‐free piezoceramics with Bi0.5Na0.5TiO3 monocrystal platelets as bricks and amorphous silica as mortar. The alignment of the bricks and the presence of the amorphous silica led to anisotropic residual stresses. These residual stresses increase the samples toughness, strength and durability while the brick alignment ...

Delta-like 4 is indispensable in thymic environment specific for T cell development. [PDF]

, 2008
The thymic microenvironment is required for T cell development in vivo. However, in vitro studies have shown that when hematopoietic progenitors acquire Notch signaling via Delta-like (Dll)1 or Dll4, they differentiate into the T cell lineage in the ...
