Abstract The behavior of current density accumulation around the sharp gradient magnetic field structure or a 3D null point and with presence finite plasma pressure is investigated. It has to be stated that in this setup, fan plane locates at xy spine axis aligns along z -axis. Current generation acts as barrier for developing less well understood. shock-capturing Godunov-type PLUTO code used s...

Coronal jets are eruptions identified by a collimated, sometimes twisted spire. They small-scale energetic events compared with flares. Using multi-wavelength observations from the Solar Dynamics Observatory/Atmospheric Imaging Assembly (SDO/AIA) and magnetogram Hinode/Spectro-Polarimeter (Hinode/SP), we study formation evolution of jet occurring on 2019 March 22 in active region NOAA 12736. A ...

ABSTRACT We study the formation and evolution of jets in solar atmosphere using numerical simulations partially ionized plasma. The two-fluid magnetohydrodynamic equations with ion+electron neutral hydrogen components are used two-dimensional Cartesian geometry. Numerical show that a localized non-linear Gaussian pulse ion pressures initially launched from magnetic null point potential arcade l...

Glutathione S-transferases (GSTs; EC: 2.5.1.18) are a ubiquitous family of eukaryotic and prokaryotic phase II metabolic isozymes. Genes encoding GSTM1 (OMIM: 138350), and GSTT1 (OMIM: 600436) are members of class mu and theta, respectively. The most common polymorphism in the GSTM1 is a deletion of the whole GSTM1 gene with a lack of enzyme activity. A homozygous deletion in the GSTT1 has also...

The problem of testing a point null hypothesis (or a "small interval" null hypothesis) isconsidered. Of interest is the relationship between the P value (or observed significance level) and conditional nd Bayesian measures of evidence against he null hypothesis. Although one might presume that a small P value indicates the presence of strong evidence against he null, such is not necessarily the...

in this paper, a new method was proposed for the navigation of a mobile robot in an unknown dynamic environment. the robot could detect only a limited radius of its surrounding with its sensors and it went on the shortest null space (sns) toward the goal. in the case of no obstacle, sns was a direct path from the robot to goal; however, in the presence of obstacles, sns was a space around the r...

We construct invariants for bosonic and spinning tensionless (null) strings in backgrounds that carry Killing tensors or Killing-Yano of mixed type. This is facilitated by the close relation these to point particles. apply construction Minkowski Kerr-Newman backgrounds.

Researchers sometimes argue that their exposure-measurement errors are independent of other errors and are nondifferential with respect to disease, resulting in estimation bias toward the null. Among well-known problems with such arguments are that independence and nondifferentiality are harder to satisfy than ordinarily appreciated (e.g., because of correlation of errors in questionnaire items...
