The Relation between Ion Temperature Anisotropy and Formation of Slow Shocks in Collisionless Magnetic Reconnection [PDF]

open access: yes, 2012
We perform a two-dimensional simulation by using an electromagnetic hybrid code to study the formation of slow-mode shocks in collisionless magnetic reconnection in low beta plasmas, and we focus on the relation between the formation of slow shocks and ...

Investigating the performance of simplified neutral‐ion collisional heating rate in a global IT model [PDF]

open access: yes, 2016
The Joule heating rate has usually been used as an approximate form of the neutral‐ion collisional heating rate in the thermospheric energy equation in global thermosphere‐ionosphere models.

Quasinormal modes of black holes: from astrophysics to string theory

open access: yes, 2011
Perturbations of black holes, initially considered in the context of possible observations of astrophysical effects, have been studied for the past ten years in string theory, brane-world models and quantum gravity.

Novel cyanobacterial bioreporters of phosphorus bioavailability based on alkaline phosphatase and phosphate transporter genes of Anabaena sp. PCC 7120 [PDF]

open access: yes, 2012
There is heterogeneity in the way cyanobacteria respond to P starvation and subsequently how they adapt to environments with low or fluctuating P concentrations. In this study, we have fused the promoterless lux operon luxCDABE to the promoter regions of

Streptococcus pyogenes Causing Skin and Soft Tissue Infections Are Enriched in the Recently Emerged emm89 Clade 3 and Are Not Associated With Abrogation of CovRS. [PDF]

open access: yes, 2018
Although skin and soft tissue infections (SSTI) are the most common focal infections associated with invasive disease caused by Streptococcus pyogenes (Lancefield Group A streptococci - GAS), there is scarce information on the characteristics of isolates

Coupling Filter-Based Thermal Desorption Chemical Ionization Mass Spectrometry with Liquid Chromatography/Electrospray Ionization Mass Spectrometry for Molecular Analysis of Secondary Organic Aerosol [PDF]

open access: yes, 2020
Filter-based thermal desorption (F-TD) techniques, such as the filter inlet for gases and aerosols, are widely employed to investigate the molecular composition and physicochemical properties of secondary organic aerosol (SOA).
