Measuring the Hall Effect in Hysteretic Materials

Advanced Materials, EarlyView.
The authors highlight common pitfalls in measuring the Hall effect: in hysteretic magnets, improper data processing can create signals that look exotic but are not real. This Perspective explains the origin of these artifacts and presents practical measurement strategies that help researchers identify reliable Hall responses in complex magnetic ...

Resonant Domain Wall Dynamics in a Three‐Dimensional Magnetic Nano Double Helix

Advanced Materials, EarlyView.
3D magnetic nanostructures promise exciting possibilities for magnetization dynamics. However, experimental realizations remain scarce. In nanoprinted cobalt double helices, time‐resolved X‐ray microscopy reveals harmonic domain wall dynamics. Simulations identify the mode and additional higher‐frequency resonances, revealing a rich dynamic landscape ...

Night-restricted feeding preserves the ovarian circadian rhythm of IL-17 and promotes follicular development in prepubertal and pubertal rabbits

Journal of Ovarian Research
Background Irregular sleep and eating patterns in modern lifestyles may disrupt reproductive rhythms, thereby impairing reproductive function in adult women.

Oscillations in Notch Signaling Regulate Maintenance of Neural Progenitors

, 2008
SummaryExpression of the Notch effector gene Hes1 is required for maintenance of neural progenitors in the embryonic brain, but persistent and high levels of Hes1 expression inhibit proliferation and differentiation of these cells.

Conductive Hydrogels for Exogenous Sensing and Cell Fate Control

Advanced Materials, EarlyView.
We engineer electrically conductive hydrogels by combining sulfated glycosaminoglycans with semiconducting polymers. These hydrogels bind bioactive proteins, including growth factors, whose release or retention can be modulated by low‐voltage stimulation. The hydrogels are also integrated as 3D channels in organic electrochemical transistors as part of

Simulating Biochemical Signaling Networks in Complex Moving Geometries

, 2010
Signaling networks regulate cellular responses to environmental stimuli through cascades of protein interactions. External signals can trigger cells to polarize and move in a specific direction.

Rational Tuning of Hygroscopic Oscillation of Stacked Nanoflake Assemblies for Continuous Ambient Energy Harvesting

Advanced Materials, EarlyView.
Stacked nanoflake assembly (SNA) membranes can oscillate autonomously, offering opportunities for soft actuation and energy harvesting. This work uncovers the physical mechanism behind the sustained oscillation of SNA membranes in gradient humidity and identifies three governing dimensionless parameters, enabling rational design for optimizing SNA ...

Calcium oscillations in mesenchymal stem cells, a control on cell cycle progression to influence cell fate towards proliferation or differentiation?

Stem Cell Research & Therapy
Background Under regular culture conditions, mesenchymal stem cells (MSCs) exhibit cytosolic calcium concentration oscillations (Ca2+ oscillations), that change, especially in frequency, after the differentiation of the MSCs.

Experimental Study on Cytoplasmic Calcium Oscillation in MG-63 Cells Induced by Pressure-Driven Fluid Flow

, 2009
This paper determined the optimal periodic mechanical stimulation of live bone cells from the intracellular calcium oscillation induced by shear stress. The shear stress-induced intracellular calcium responses of cells on a micro-cell chip were measured ...
