A note on Maxwell's equal area law for black hole phase transition
The state equation of the charged AdS black hole is reviewed in the
plane. Thinking of the phase transition, the , , graphs are
plotted and then the equal area law is used in the three cases to get the phase
transition point (P,T). The analytical phase transition point relations for P-T
of charged AdS black hole has been obtained successfully. By comparing the
three results, we find that the equal area law possibly cannot be used directly
for plane. According to the , results, we plot the
graph and find that for a highly charged black hole a very low temperature
condition is required for the phase transition

Calcineurin B-Like Proteins CBL4 and CBL10 Mediate Two Independent Salt Tolerance Pathways in Arabidopsis.
In Arabidopsis, the salt overly sensitive (SOS) pathway, consisting of calcineurin B-like protein 4 (CBL4/SOS3), CBL-interacting protein kinase 24 (CIPK24/SOS2) and SOS1, has been well defined as a crucial mechanism to control cellular ion homoeostasis by extruding Na+ to the extracellular space, thus conferring salt tolerance in plants. CBL10 also plays a critical role in salt tolerance possibly by the activation of Na+ compartmentation into the vacuole. However, the functional relationship of the SOS and CBL10-regulated processes remains unclear. Here, we analyzed the genetic interaction between CBL4 and CBL10 and found that the cbl4 cbl10 double mutant was dramatically more sensitive to salt as compared to the cbl4 and cbl10 single mutants, suggesting that CBL4 and CBL10 each directs a different salt-tolerance pathway. Furthermore, the cbl4 cbl10 and cipk24 cbl10 double mutants were more sensitive than the cipk24 single mutant, suggesting that CBL10 directs a process involving CIPK24 and other partners different from the SOS pathway. Although the cbl4 cbl10, cipk24 cbl10, and sos1 cbl10 double mutants showed comparable salt-sensitive phenotype to sos1 at the whole plant level, they all accumulated much lower Na+ as compared to sos1 under high salt conditions, suggesting that CBL10 regulates additional unknown transport processes that play distinct roles from the SOS1 in Na+ homeostasis
N-(2-Chlorobenzoyl)-N′-(3-pyridyl)thiourea
In the molecule of the title compound, C13H10ClN3OS, the dihedral angles between the plane through the thiourea group and the pyridine and benzene rings are 53.08 (3) and 87.12 (3)°, respectively. The molecules are linked by intermolecular N—H⋯N hydrogen-bonding interactions to form a supramolecular chain structure along the a axis. An intramolecular N—H⋯O hydrogen bond is also present
Diaquabis(4-carboxy-2-propyl-1H-imidazole-5-carboxylato-κ2 N 3,O 4)copper(II) N,N-dimethylformamide disolvate
In the title complex, [Cu(C8H9N2O4)2(H2O)2]·2C3H7NO, the CuII ion, lying on an inversion center, is six-coordinated in a slightly distorted octahedral geometry. Two N atoms and two O atoms from two H2pimda (H3pimda is 2-propyl-1H-4,5-dicarboxylic acid) ligands are in the equatorial plane. The axial positions are occupied by two O atoms from two water molecules. A two-dimensional supramolecular network parallel to (001) is constructed by N—H⋯O and O—H⋯O hydrogen bonds. An intramolecular O—H⋯O hydrogen bond is also observed
SUPRASPECIFIC TAXA OF THE BIVALVIA FIRST NAMED, DESCRIBED, AND PUBLISHED IN CHINA (1927–2007)
A total of 209 bivalve generic (subgeneric) and 19 familial (subfamilial) names first proposed by Chinese palaeontologists and published in China are treated herein as an annotated database. The present paper is designed especially for the Treatise on Invertebrate Paleontology Bivalvia revision project, because access to bivalve taxa published by Chinese authors in China has been difficult for non-Chinese researchers. The original diagnoses of these taxa, including the original descriptions and explanation of figures of all the type species, have been translated from Chinese into English, so that non-Chinese colleagues can more easily have access to them

Paper-based electroanalytical devices with an integrated, stable reference electrode
This paper describes the development of a referenced Electrochemical Paper-based Analytical Device (rEPAD) comprising a sample zone, a reference zone, and a connecting microfluidic channel that includes a central contact zone. We demonstrated that the rEPADs provide a simple system for direct and accurate voltammetric measurements that are referenced by an electrode with a constant, well-defined potential. The performance of the rEPADs is comparable to commercial electrochemical cells, and the layout can be easily integrated into systems that permit multiplexed analysis and pipette-free sampling. The cost of this portable device is sufficiently low that it could be for single-use, disposable applications, and its method of fabrication is compatible with that used for other paper-based systems.Chemistry and Chemical Biolog
