Entanglement Swapping in Two Independent Atom-Cavity-Optomechanical Systems
Qing-Hong Liao,Qi Zhang,Nan-Run Zhou,Xin Liu 한국물리학회 2016 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.69 No.4
We investigate the dynamics of entanglement between two remote, macroscopic, mechanical modes in a model consisting of two cavities, with each cavity containing a two-level atom and having one movable mirror. The results show that the time evolution of entanglement exhibits periodic behavior that does not depend on the atomic coherent angles and that the amount of entanglement increases with increasing atomic coherent angle. A maximally entangled state between mechanical modes can be prepared. We find a simple method for inferring the entanglement properties between two mechanical modes. We propose a potential way to control and manipulate the entanglement.

Natural ester is a suitable substitute for mineral oil and has been widely used in AC transformer in many countries. In order to further application of natural ester in direct current (DC) equipment, it is needed to investigate its long term insulation property under DC condition. In this paper, a thermal ageing experiment was conducted for both mineral oil-paper and natural ester-paper insulation. The DC breakdown and space charge characteristics of insulation paper impregnated with natural ester and mineral oil was compared. Results show that the resistivity of the paper immersed in natural ester and mineral oil both increase as the ageing goes on. While insulation paper impregnated with natural ester has higher resistivity and DC breakdown voltage than the paper impregnated with mineral oil. The DC breakdown voltage for the oil impregnated insulation paper being DC prestressing is higher than that without pre-stressing. The average DC breakdown field strength difference between the test with pre-stressing and without pre-stressing clearly shows that there is an apparent enhancement effect for the homo-charge injection on the DC breakdown.

In our previous study, miRNA-183, a miRNA in the miR-96-182-183 cluster, was significantly over-expressed in esophageal squamous cell carcinoma (ESCC). In the present study, we explored the oncogenic roles of miR-183 in ESCC by gain and loss of function analysis in an esophageal cancer cell line (EC9706). Genome-wide mRNA microarray was applied to determine the genes that were regulated directly or indirectly by miR-183. 3UTR luciferase reporter assay, RT-PCR, and Western blot were conducted to verify the target gene of miR-183. Cell culture results showed that miR-183 inhibited apoptosis (p < 0.05), enhanced cell proliferation (p < 0.05), and accelerated G1/S transition (p < 0.05). Moreo-ver, the inhibitory effect of miR-183 on apoptosis was rescued when miR-183 was suppressed via miR-183 inhibitor (p < 0.05). Western blot analysis showed that the expression of programmed cell death 4 (PDCD4), which was predicted as the target gene of miR-183 by microarray profiling and bioinformatics predictions, decreased when miR-183 was over-expressed. The 3'UTR luciferase reporter assay confirmed that miR-183 directly regulated PDCD4 by binding to sequences in the 3'UTR of PDCD4. Pearson correlation analysis fur-ther confirmed the significant negative correlation between miR-183 and PDCD4 in both cell lines and in ESCC patients. Our data suggest that miR-183 might play an oncogenic role in ESCC by regulating PDCD4 expression.

Molecule-based electrorheological (ER) materials with luminescence property, based on ${\beta}$-cyclodextrin [($C_6O_5H_{10})_7$, ${\beta}$-CD] inclusion compounds between ${\beta}$-CD (host) and the rare earth (RE) (RE=Tb, Eu) complex (guest), have been synthesized as a novel type of ER materials using ${\beta}$-CD, $Tb(NO_3)_3$, $Eu(NO_3)_3$, sulphosalicylic acid ($C_7H_6O_6S{\cdot}2H_2O$, SSA) and m-phthalic acid ($C_8H_6O_4$, MPA) as original materials. The composition, ER performance, luminescence property and dielectric property of the materials have been studied. The results show that the rare earth complex in the cavity of ${\beta}$-CD may enhance the ER performance of ${\beta}$-CD, and the complex (Tb-SSA) of $Tb^{3+}$ can improve more effectively the ER activity of ${\beta}$-CD than that (Eu-MPA) of $Eu^{3+}$ among both of the complexes. The composition and structure are the dominant factors in improving the ER effect. The fluorescence intensity, fluorescence lifetime and emission quantum yield of the particle materials and their suspensions in silicone oil have been tested, and fine luminescence performance has been detected. The material with ER activity and luminescence performance is a novel multifunctional material which would have wide application prospect.

Three kinds of electrorheological (ER) materials with carboxyl, amido and hydroxyl group, respectively, were synthesized by a simple adsorption method. The powder of silicon dioxide as a substrate of the materials, as well as terephthalic acid [$p-C_6H_4(COOH)_2$, abbr.: phen-COOH], p-phenylenediamine [$p-C_6H_4(NH_2)_2$, abbr.: $phen-NH_2$] and hydroquinone [$p-C_6H_4(OH_2)_2$, abbr.: phen-OH] were chosen as starting materials. The ER properties of suspensions of the materials in silicon oil were studied. The suspension of the material adsorbing phen-COOH reveals the highest ER activity, the relative shear stress of the suspension (25 wt%), ${\tau}_r(={\tau}_E/{\tau}_0,\;{\tau}_E\;and\;{\tau}_0$ are the shear stresses at electric field strengths of E=4.2 and 0 kV/mm, respectively), reaches 220 under a DC electric field at a shear rate of $14.5s^{-1}$. The shear stress of the suspension of the material adsorbing $phen-NH_2$ is the largest at an high electric field strength. The ER activity of the material adsorbing phen-OH is the lowest among the three materials. The molecule structure is an importance factor in influencing ER performance of the materials for similar compounds with different polar function groups. The relationship between the ER activity and dielectric property of the materials was discussed.

Background Sinonovacula constricta is an economically important bivalve species in China, Korea and Japan that widely resides in estuarine and coastal areas where salinity fluctuates rapidly. However, little is known about its adaptation mechanisms to acute salt stresses. Objective To reveal the underlying molecular mechanisms involved in acute salt stresses in juvenile S. constricta. Methods Nine cDNA libraries (triplicate each trial) were established from juvenile S. constricta, which were subjected to low salinity (5 psu), optimal salinity (15 psu) and high salinity (25 psu) for 6 h, respectively. Results Illumina sequencing generated 478,587,310 clean reads totally, which were assembled into 427,057 transcripts of 246,672 unigenes. Compared with the control, 1259 and 2163 differentially expressed genes (DEGs) were identified under acute low and high salt stresses, respectively. GO and KEGG enrichment analyses of DEGs revealed that several key metabolic modulations were mainly responsible for the acute salt stresses. According to the significantly highlighted KEGG pathways, some key DEGs were identified and discussed in details. Notably, based on which, some potential osmolytes were further speculated. Conclusion Here, we carried out a unique report of comparative transcriptome analyses in juvenile S. constricta in response to acute salt stresses. The identified DEGs and their significantly enriched GO terms and KEGG pathways were critical for understanding and further investigating the underlying the physical and biochemical performances, and ultimately facilitated S. constricta breeding. Besides, the transcriptome data greatly enriched the genetic information of S. constricta, which were valuable for promoting its molecular biology researches.
