Assessing bacterial magnetotactic behavior by using permanent magnet blocks
Assessing the movement of magnetotactic bacteria (MTB) under magnetic fields is a key to exploring the function of the magnetotaxis. In this study, a simple method was used to analyze the behavior of MTB, whic...

Overexpression of PITPNM3 promotes hepatocellular carcinoma cell metastasis
A previous study indicated that C–C chemokine (C–C motif) ligand 18 (CCL18) is capable of inducing tumor cell invasion and metastasis by interacting with receptor membrane-associated phosphatidylinositol trans...

Genome-wide analysis of nucleotide-binding site disease resistance genes in Medicago truncatula
The class of nucleotide-binding site (NBS)-Leucine-rich repeat (LRR) disease resistance genes play an important role in defending plants from a variety of pathogens and insect pests. Consequently, many NBS-LRR...

Arabidopsis calcium-dependent protein kinase CPK28 is potentially involved in the response to osmotic stress
As calcium sensors, plant calcium-dependent protein kinases (CDPKs) play important roles in plants’ responses to various abiotic stresses. Here, we report the functional characterization of CPK28, a member of ...

Discovery of Late Carboniferous strata and their tectonic significance in the southern margin of the North China Block (Huoqiu and Gushi areas)
Late Carboniferous fossils (such as Boultonia? sp., Tabulata, and spiriferoid specimens with smooth shells), bioclastic material (such as crinoid stems and sponge fragments), and Late Ordovician microfossils of t...

An efficient non-iterative algorithm to estimate the apparent diffusion coefficient of water molecules in the magnetic resonance diffusion imaging experiments
Many studies have shown that the magnetic resonance signal decay with an extend range of diffusion weighting (b-factor) is a bi-exponential attenuation in the diffusion-weighted magnetic resonance imaging experim...

Entrainment-mixing parameterization in shallow cumuli and effects of secondary mixing events
Parameterization of entrainment-mixing processes in cumulus clouds is critical to improve cloud parameterization in models, but is still at its infancy. For this purpose, we have lately developed a formulation...

Quadratic Yukawa coupling and matrix Yukawa coupling in the large N expansion
In this article, we study three types of new Yukawa couplings (the boson field is coupled to the fermion field). Two of them are quadratic Yukawa couplings (the boson field is in the form of a vector), and the...

Analysis of the dominant frequency in a subsonic compressor stator at near stall condition
IDDES method was applied to investigate the highly unsteady flow in a subsonic compressor stator with very large hub clearance and high incidence angle. The blade loading variation frequency was found close to...
