Advanced Materials, EarlyView.A fully flexible ion‐gel‐gated graphene‐channel transistor driven by a triboelectric nanogenerator enables self‐powered tactile sensing and synaptic learning. Mimicking spike‐rate‐dependent plasticity, the device exhibits frequency‐selective potentiation and depression, supporting rate‐coded neuromorphic computation even under flex.

Exploring the Mass–Metallicity Relationships with the DESI BGS and ELG Samples
The Astronomical JournalThe mass–metallicity relation (MZR) serves as a cornerstone for understanding the chemical evolution of galaxies by correlating the stellar mass of galaxies with their gas-phase metallicity.

From voids to filaments: environmental transformations of galaxies in the SDSS
, 2017 We investigate the impact of filament and void environments on galaxies, looking for residual effects beyond the known relations with environment density. We quantified the host environment of galaxies as the distance to the spine of the nearest filament,

Lensing Properties of Scale‐free Galaxies [PDF]
The Astrophysical Journal, 2001 The multiple images of lensed quasars provide evidence on the mass distribution of the lensing galaxy. The lensing invariants are constructed from the positions of the images, their parities and their fluxes. They depend only on the structure of the lensing potential.

On the Effects of Local Environment on Active Galactic Nucleus (AGN) in the Horizon Run 5 Simulation
The Astrophysical Journal, 2023 We use the Horizon Run 5 cosmological simulation to study the effect of galaxy intrinsic properties and the local environment on active galactic nuclei (AGNs) characterized by their threshold of the accretion rate.

Modeling vertical structure in circular velocity of spiral galaxy NGC 4244
, 2015 We study the vertical gradient in azimuthal velocity of spiral galaxy NGC 4244 in a thin disk model. With surface density accounting for the rotation curve, we model the gradient properties in the approximation of quasi-circular orbits and find the ...

Mass segregation trends in SDSS galaxy groups [PDF]
, 2014 It has been shown that galaxy properties depend strongly on their host environment. In order to understand the relevant physical processes driving galaxy evolution it is important to study the observed properties of galaxies in different environments ...
