Controlled Formation of Skyrmion Bags

Advanced Materials, EarlyView.
This work demonstrates stabilization of complex magnetic skyrmion bags in ferromagnetic thin films through precisely engineered anisotropy defects using ion irradiation. The researchers achieve controlled field‐ and laser‐induced generation of skyrmionia, target skyrmions, and higher‐order skyrmion bags at room temperature. This reliable platform opens

Stochastic geometry sensing and polarization in a lipid kinase–phosphatase competitive reaction

Proceedings of the National Academy of Sciences of the United States of America, 2019
Significance Spatial gradients of phosphatidylinositol phosphate (PIP) lipids in the cell membrane regulate a variety of cellular processes, including endocytosis, phagocytosis, and cell migration. The molecules that control these cellular processes must

QoE and Cost for Wireless Networks With Mobility Under Spatio-Temporal Traffic

IEEE Access, 2019
Mobility is a key factor that influences the spatial and temporal fluctuation of wireless traffic, which is highly coupled with the user experience. Previous researches barely explore the properties of the traffic when the mobility is considered. In this

Organic Ferroelectric Synaptic Transistors for Neural Image Recognition Networks

Advanced Materials Interfaces, EarlyView.
All organic transistors, where both the dielectric and semiconducting layers are polymeric, are developed as electrical synaptic devices. Two copolymers of PVDF as the dielectric layer with large differences in their saturation polarizability and memory window are chosen.

A Stochastically Geometrical Poisson Point Process Approach for the Future 5G D2D Enabled Cooperative Cellular Network

IEEE Access, 2019
Due to recent developments in the cellular communication system, stochastic process implementation is necessary. The cellular communication system exhibits random patterns in various domains, thereby compelling the utilization of stochastic processes to ...

Stochastic Properties of Dynamical Systems Arising from (quantum) Spaces and Actions of Groups [PDF]

arXiv, 2013
We review novel results and investigate actions and transformations of groups and semigroups on (quantum) spaces, present dynamical systems and zeta functions arising from these spaces, actions and transformations, discuss their stochastic properties.

Interfacial Yield Stress Response in Synthetic Mucin Solutions

Advanced Materials Interfaces, EarlyView.
The solution rheology of novel synthetic mucins mimicking natural mucin domains is studied. Like many natural mucin solutions, apparent solid‐like rheology is seen. However, no bulk structural features are found to explain it. Interfacial rheology and robust modelling reveal that this arises from molecular associations at the air–water interface ...

Parameterized Two‐Qubit Gates for Enhanced Variational Quantum Eigensolver

Annalen der Physik, Volume 534, Issue 12, December 2022., 2022
The parameterized quantum circuit used in variational quantum algorithms usually consists of parameterized single‐qubit gates and fixed entangling multi‐qubit gates. Here, it is considered what happens when the entangling gates become parameterized, which allows for directly tuning the entangling power of the circuit. The parameterized entangling gates
