Single-atom entropy squeezing and quantum entanglement in Tavis-Cummings model with atomic motion

引用

Chinese Physics B 2010年第7期19卷 276-283页

作者：邹艳 Department of Physics Dezhou University key Biophysics laboratory in universities of shandong

We examine the single-atom entropy squeezing and the atom-field entanglement in a system of two moving twolevel atoms interacting with a single-mode coherent field in a lossless resonant cavity. Our numerical calculations indicate that the squeezing period, the squeezing time and the maximM squeezing can be controlled by appropriately choosing the atomic motion and the field-mode structure. The atomic motion leads to a periodical time evolution of entanglement between the two-atom and the field. Moreover, there exists corresponding relation between the time evolution properties of the atomic entropy squeezing and that of the entanglement between the two atoms and the field.

Sexual reproduction first appeared in unicellular protists and has continued to be an essential biological process in almost all *** protists, which contain both germline and somatic genomes within a single cell, have evolved a special form of sexual reproduction called conjugation that involves mitosis, meiosis, fertilization, nuclear differentiation, genome rearrangement, and the development of unique cellular structures. The molecular basis and mechanisms of conjugation vary dramatically among ciliates, and many details of the process and its regulation are still largely unknown. In order to better comprehend these processes and mechanisms from an evolutionary perspective, this study provides the first comprehensive overview of the transcriptome and proteome profiles during the entire life cycle of the newly-established marine model ciliate Euplotes vannus. Transcriptome analyses from 14 life cycle stages(three vegetative stages and 11 sexual stages) revealed over 26,000 genes that are specifically expressed at different stages, many of which are related to DNA replication,transcription, translation, mitosis, meiosis, nuclear differentiation, and/or genome rearrangement. Quantitative proteomic analyses identified 338 proteins with homologs associated with conjugation and/or somatic nuclear development in other ciliates, including dicer-like proteins, Hsp90 proteins, RNA polymerase Ⅱ and transcription elongation factors, ribosomal-associated proteins, and ubiquitin-related proteins. Four of these homologs belong to the PIWI family, each with different expression patterns identified and confirmed by RT-qPCR,which may function in small RNA-mediated genome rearrangement. Proteins involved in the nonhomologous end-joining pathway are induced early during meiosis and accumulate in the developing new somatic nucleus, where more than 80% of the germline sequences are eliminated from the somatic genome. A number of new candidate genes and proteins likely t

Effects of 1-octyl-3-methylimidazolium nitrate on the microbes in brown soil

引用

Journal of Environmental Sciences 2018年第5期30卷 249-259页

作者： Cheng Zhang Jun Wang Lusheng Zhu Zhongkun Du Jinhua Wang Xi Sun Tongtong Zhou key laboratory of Agriculture Environment in universities of shandong College of Resources and Environment Shandong Agricultural University

The toxicity of ionic liquids（ILs） on soil organisms has aroused wide attention due to their high-solubility. The present investigation focused on the toxicity of 1-octyl-3-methylimidazolium nitrate（[C8mim]NO3） on the microbial populations（bacteria, fungi, and actinomycetes）, soil enzyme（urease, dehydrogenase, acid phosphatase, and β-glucosidase）activities, microbial community diversity using terminal restriction fragment length polymorphism（T-RFLP）, and abundance of the ammonia monooxygenase（amoA） genes of ammonia-oxidizing archaea（AOA） and ammonia-oxidizing bacteria（AOB） using quantitative real-time polymerase chain reaction（q-PCR） in brown soil at each trial with doses of 0, 1.0, 5.0,and 10.0 mg/kg on days 10, 20, 30, and 40. The contents of [C8mim]NO3 in soil were measured using high performance liquid chromatography with recoveries of 84.3% to 85.2%, and changed less than 10% during the experimental period. A significant decrease was observed from the bacteria, fungi and actinomycetes populations at 10.0 mg/kg, at which the urease activity was inhibited and the β-glucosidase activity was stimulated on days 20, 30, and 40. In addition, [C8mim]NO3 inhibited the dehydrogenase activity at 10 mg/kg on days 30 and 40 and the acid phosphatase activity on day 20. The diversity of the soil microbial community and the gene abundance of AOA-and AOB-amo A were also inhibited. Furthermore, the present investigation provided more scientific information for the toxicity evaluation of ILs in soil.

Inflammation is a driving force of hematopoietic stem cells(HSCs) aging, causing irreversible exhaustion of functional HSCs. However, the underlying mechanism of HSCs erosion by inflammatory insult remains poorly understood. Here, we find that transient LPS exposure primes aged HSCs to undergo accelerated differentiation at the expense of self-renewal, leading to depletion of HSCs. Meanwhile, the central regulator nuclear factor kappa B(NF-κB) mediating functional impairment by inflammation insult induces differential transcriptional response in aged HSCs compared with young HSCs, with precocious activation of myeloid lineage genes. Altered compartmentalization and chromatin loop formation are associated with aging-related differential transcriptional response in HSCs upon lipopolysaccharide(LPS)stimulation. Mechanistically, enhancer and promoter regions of myeloid lineage genes in aged HSCs are more accessible and display more rapid and prominent CTCF occupancy upon LPS stimulation. Our study provides comprehensive resources for the three-dimensional(3D)genome structure of HSCs and sheds light into the ordered genome organization and the associated transcriptome signature underlying HSCs aging.

Cultivation Ages Effect on Soil Physicochemical Properties and Heavy Metal Accumulation in Greenhouse Soils

引用

Chinese Geographical Science 2018年第4期28卷 717-726页

作者： WANG Jun MI Wenkui SONG Peipei XIE Hui ZHU Lusheng WANG Jinhua College of Resources and Environment Key Laboratory of Agricultural Environment in Universities of Shandong Shandong Agricultural University

The intensive management practices in greenhouse production may alter the soil physicochemical properties and contribute to the accumulation of heavy metals(HMs). To determine the HM concentrations in vegetable soil in relation to soil physicochemical properties and cultivation age, we conducted a soil survey for typical greenhouse soils in Shouguang, China. The results indicated that Cd is a major HM pollutant in the tested soils, as the only HM element exceeding the allowed limit for vegetable soil. The surveyed data was analyzed with regression analysis, correlation analysis and canonical correspondence analysis(CCA). A positive correlation is observed between HM pollution level and cultivation age. CCA results suggest that the HM pollution level and distribution in soil are significantly affected by soil physicochemical properties, which was a function of years of cultivation as revealed by regression analysis. In summary, cultivation age is an important factor to affect soil physicochemical properties(organic matter and inorganic nutrients) as well as HM contamination.
