Radar High Resolution Range & Micro-Doppler Analysis of Human Motions [PDF]

, 2009
In radar imaging it is well known that relative motion or deformation of parts of illuminated objects induce additional features in the Doppler frequency spectra.

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 ...

Pulmonary Delivery of siRNA Anti‐TNFα‐loaded Lipid Nanoparticles for Rapid Recovery in Murine Acute Lung Injury

Advanced Healthcare Materials, EarlyView.
In a murine model of acute lung injury, pulmonary administration of lipid nanoparticles carrying TNFα siRNA enables targeted delivery to immune cells. The study emphasises the importance of optimizing LNP distribution and delivery timing to improve therapeutic outcomes and develop emergency therapies for lung hyperinflammation.

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.

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).

Porous Decellularized Nerve Grafts Facilitate Recellularization and Nerve Regeneration in a Rat Model of Critical Long‐Gap Peripheral Nerve Injury

Advanced Healthcare Materials, EarlyView.
A decellularized nerve graft (DNG) is modified to generate a porous DNG (PDNG). The PDNG is used to repair a 30‐mm peripheral nerve injury (PNI) defect, and is compared with isograft, serving as the standard, and DNG, a widely used alternative. The result shows that PDNG facilitated nerve regeneration in long‐gap PNI, evidenced by better‐aligned axonal

Seeing inside the Body Using Wearable Sensing and Imaging Technologies

Advanced Healthcare Materials, EarlyView.
This review explores wearable technologies for noninvasive internal health monitoring. It categorizes approaches into indirect sensing (e.g., bioelectrical and biochemical signals) and direct imaging (e.g., wearable ultrasound and EIT), highlighting multimodal integration and system‐level innovation toward personalized, continuous healthcare.

Sharing a common origin between the rotational and linear doppler effects [PDF]

, 2017
The well-known linear Doppler effect arises from the linear motion between source and observer, while the less well-known rotational Doppler effect arises from the rotational motion.

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.

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 ...
