Selective Lipolysis by Photoactivation of Chaperone‐Mediated Autophagy Using Adipocyte Membrane‐Coated Nanoparticle in Hydrogel

Advanced Materials, EarlyView.
Adipocyte membrane‐coated nanoparticles loaded with rosiglitazone in hydrogel offer an alternative approach to conventional obesity treatments. This system selectively targets adipocytes, inducing lipolysis by activating chaperone‐mediated autophagy through mild photothermal stimulation.

A Uniform Correlation between Synchrotron Luminosity and Doppler Factor in Gamma-ray Bursts and Blazars: hint of similar intrinsic luminosities?

, 2011
We compile 23 Gamma-ray Bursts (GRBs) and 21 blazars with estimated Doppler factors, and the Doppler factors of GRBs are estimated from their Lorentz factors by assuming their jet viewing angles \theta->0 degree.

The Oblate Schwarzschild Approximation for Light Curves of Rapidly Rotating Neutron Stars [PDF]

, 2007
We present a simple method for including the oblateness of a rapidly rotating neutron star when fitting X-ray light curves. In previous work we showed that the oblateness induced by rotation at frequencies above 300 Hz produces a geometric effect which ...

Interactions Between Active Matters and Endogenous Fields

Advanced Materials, EarlyView.
This review synthesizes endogenous field information and computational methods in contexts such as cancer, wounds, and biofilms. It organizes NAMs and AAMs by sensing, transmitting, and executing functions, compares their limitations, and from these contrasts proposes design strategies for next‐generation AAMs, offering perspectives to foster ...

IDENTIFICATION OF AIR RADAR TARGETS USING THE DOPPLER EFFECT FROM A HEATED JET ENGINE

Вестник Дагестанского государственного технического университета: Технические науки, 2018
Objectives The aim of the study is to develop a methodology for identifyingaircraft by the deflections of an electromagnetic radar beam by a heated jet engine. Methods Atoms of the crystal lattice of the metallic parts of the operating jet engine will be

Research Advances on the Rotational Doppler Effect of Vortex Electromagnetic Waves

Leida xuebao, 2021
Traditional radars can detect moving targets using the Doppler effect. However, traditional radars have shadow areas in detecting the angular motion of the rotating targets.

Blazar sequence - an artefact of Doppler boosting

, 2008
The blazar sequence is a scenario in which the bolometric luminosity of the blazar governs the appearance of its spectral energy distribution. The most prominent result is the significant negative correlation between the synchrotron peak frequencies and ...

Time-delay and Doppler tests of the Lorentz symmetry of gravity [PDF]

, 2009
Modifications to the classic time-delay effect and Doppler shift in General Relativity (GR) are studied in the context of the Lorentz-violating Standard-Model Extension (SME).
