In this paper, we investigate the shadows and rings of the charged Horndeski black hole illuminated by accretion flow that is both geometrically and optically thin. We consider two types of accretion models: spherical and thin-disk accretion flow. We find that in both types of models, the si...
NASA’s Solar Dynamics Observatory documented a dramatic solar event on March 2, 2012. This explosion, appearing on the right side of the sun in the photograph, is called a “prominence eruption.” The prominence is made up of plasma—matter in an ultra-high-energy state even more volatile ...
Detection of cancer in human organs at an early stage is a crucial task and is important for the survival of the patients, especially in terms of complex s
NASA has been bringing the public into space through its beautiful and revelatory Image and Video Library. Of the more than 140,000 images and audio and video clips, Stacker highlighted 31 of the most breathtaking.
Association of plasma homocysteine concentration with cerebral white matter hyperintensity on magnetic resonance images in stroke patients[J] . Yu-Lung Tseng,Yung-Yee Chang,Jia-Shou Liu,Chen-San Su,Shung-Lon Lai,Min-Yu Lan.Journal of the Neurological Sciences . 2009 (1)...
Such a multimodal approach is particularly useful for analyzing the molecular composition of complex, heterogeneous tumor tissue, which comprises several distinct tumor microenvironments. One example of such heterogeneity is tissue hypoxia, a state of low oxygen tension (pO2 values ≤2.5 mmHg) observed...
Nuclear physicists analyze the ion-collision tracks to learn about the remarkable state of matter created in RHIC’s heavy-ion collisions. This “quark-gluonplasma” is a soup of particles that mimics what the universe was like just after theBig Bang. It’s a kind of cosmic...
The detailed anatomical information of the brain provided by 3D magnetic resonance imaging (MRI) enables various neuroscience research. However, due to the long scan time for 3D MR images, 2D images are mainly obtained in clinical environments. The purpo
which satisfieseν=e−λ. The negative pressure causes freely moving particles to behave as if they were repulsed from the center, which avoids further gravitational collapse of matter and prevents the formation of singularity [42]. A medium that supports this kind of equation of state is oft...
This work analyzes patterns seen when a signal beam of spontaneous parametric downconverted light illuminates a double-slit (Young) and a coincidence pattern ("object") appears on scanning behind the double-slit arrangement and, conversely, when the conjugated idler beam is scanned spatially keeping...
