Time delay estimation method of X-ray pulsar observed profile based on the optimal frequency band

Acta Physica Sinica, 2016
In order to improve the time delay estimation accuracy of the observed profile in the X-ray pulsar based navigation, the spectral characteristics of the observed profile of X-ray pulsar and the drawback of the classical Taylor fast Fourier transform (FFT) time delay estimation method are analyzed. It is found that when estimating the time delay, we can

Ets2 Is an Activity‐Dependent Transcriptional Regulator of a Fast‐Twitch Muscle Program

The FASEB Journal, Volume 40, Issue 20, 31 October 2026.
Ets2 is a transcription factor rapidly (24 h) upregulated in skeletal muscle by fast 150 Hz, but not slow 20 Hz, stimulation patterns. Ets2 selectively translocates to nuclei of slow soleus muscle when stimulated by fast‐patterned, but not slow‐patterned, activity. Ets2 binds to a consensus DNA sequence in the troponin I fast intronic enhancer (TnIFIRE)

Machine Learning‐Assisted Design and Performance Prediction of a Compact Dual‐Band Polarization‐Insensitive THz Metamaterial Absorber for Skin‐Cancer‐Related Refractive‐Index Sensing

Advanced Electronic Materials, Volume 12, Issue 20, 26 October 2026.
A compact QASRR‐based THz metamaterial absorber enables polarization‐insensitive dual‐band absorption and skin‐cancer‐related refractive‐index sensing through measurable resonance shifts. Field, surface‐current, and circuit analyses clarify the dual‐resonance mechanism, while StackNet‐assisted prediction accurately estimates the simulated absorption ...

Solar-System Studies with Pulsar Timing Arrays

, 2017
High-precision pulsar timing is central to a wide range of astrophysics and fundamental physics applications. When timing an ensemble of millisecond pulsars in different sky positions, known as a pulsar timing array (PTA), one can search for ultra-low ...

The second data release from the European Pulsar Timing Array I. The dataset and timing analysis

, 2023
<p>Pulsar timing arrays offer a probe of the low-frequency gravitational wave spectrum (1−100 nanohertz), which is intimately connected to a number of markers that can uniquely trace the formation and evolution of the Universe. We present the

Multi‐omics integration and machine learning identify an ACKR1+ endothelial cell‐based lactate‐immune signature associated with carotid plaque vulnerability and progression

Clinical and Translational Medicine, Volume 16, Issue 10, October 2026.
ACKR1+ endothelial cells mark intraplaque neovessels with hyperactive glycolysis and lactate metabolism. Lactate, HIF‐1α and CXCL12 link this state to CXCR4+ CD8+ T‐cell recruitment in situ. SLC16A3 and SLC16A4 serve as quantitative readouts of this lactate–immune state.

Correlated timing noise and high precision pulsar timing: Measuring frequency second derivatives as an example [PDF]

, 2019
We investigate the impact of noise processes on high-precision pulsar timing. Our analysis focuses on the measurability of the second spin frequency derivative ν¨⁠. This ν¨ can be induced by several factors including the radial velocity of a pulsar.
