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

Reconstructing Quantum Geometry from Quantum Information: Spin Networks as Harmonic Oscillators

, 2005
Loop Quantum Gravity defines the quantum states of space geometry as spin networks and describes their evolution in time. We reformulate spin networks in terms of harmonic oscillators and show how the holographic degrees of freedom of the theory are ...

Fuzzy Mass Relations in the Standard Model [PDF]

, 1995
Recently Connes has proposed a new geometric version of the standard model including a non-commutative charge conjugation. We present a systematic analysis of the relations among masses and coupling constants in this approach.

Preservation of Extracellular Vesicle Integrity and Cargo Using Spiral Microfluidic Chip‐Based Separation

Advanced Materials Technologies, EarlyView.
A spiral microfluidic chip is compared with ultrafiltration for the separation of extracellular vesicles (EVs). The method preserves miRNA cargo and membrane integrity more effectively, resulting in intact vesicle morphology and consistent surface biomarker expression.

New intuitionistic fuzzy 2- normed I-convergent double sequence spaces by bounded linear operator

, 2021
Saadati and Park [Saadati. R, and Park J. H., Chaos, Solitons Fractals 2006] [14] introduced the notion of intuitionistic fuzzy normed space. Motivated by this, we introduce some intuitionistic fuzzy 2-normed I-convergent double sequence spaces defined by bounded linear operator.

Magnetic operations: a little fuzzy physics?

, 2010
We examine the behaviour of charged particles in homogeneous, constant and/or oscillating magnetic fields in the non-relativistic approximation. A special role of the geometric center of the particle trajectory is elucidated. In quantum case it becomes a

An AI‐Enabled All‐In‐One Visual, Proximity, and Tactile Perception Multimodal Sensor

Advanced Robotics Research, EarlyView.
Targeting integrated multimodal perception of robots, an AI‐enabled all‐in‐one multimodal sensor is proposed. This sensor is capable of perceiving three types of modalities, including vision, proximity, and tactility. By toggling an ultraviolet light and adjusting the camera focus, it switches smoothly between multiple perceptual modalities, enabling ...
