In this work we discuss the Landau criterion for anisotropic superfluidity. To this end we consider a pointlike impurity moving in a uniform Bose-Einstein condensate with either interparticle dipole-dipole interaction or Raman-induced spin-orbit coupling. In both cases we find that the Landau critical velocity vc is generally smaller than the sound velocity in the moving direction. Beyond vc, the energy dissipation rate is explicitly calculated via a perturbation approach. In the plane-wave phase of a spin-orbit-coupled Bose gas, the dissipationless motion is suppressed by the Raman coupling even in the direction orthogonal to the recoil momentum. Our predictions can be tested in the experiments with ultracold atoms. © 2017 American Physical Society.

This disclosure relates to a process for selectively extracting Fe(III) ions from an aqueous feedstock containing Fe(III) ions and non-ferric ions. The process comprises contacting the feedstock with an organic phase comprising a phosphonium salt or ammonium salt ionic liquid under liquid-liquid extraction conditions for a time sufficient to allow transfer of at least some of the Fe(III) ions from the feedstock to the organic phase to provide an Fe(III) ion laden organic phase and an Fe(III) depleted feed-stock, and separating the Fe(III) ion laden organic phase from the Fe(III) depleted feedstock.

The quark quasiparticle model is extended to study the properties of color-flavor locked strange quark matter at finite chemical potential and in a strong magnetic field. We present a self-consistent thermodynamic treatment by employing a chemical potential dependent bag function. It is found that the magnetized color-flavor locked (MCFL) matter is more stable than other phases within a proper magnitude of magnetic field. The stability window is graphically shown for the MCFL matter compared with ordinate magnetized matter. The anisotropic structure of MCFL matter is dominated by the magnetic field and almost independent of the energy gaps. A critical maximum magnetic field of about 1.56×1018 G is found, under which MCFL matter is absolutely stable with respect to nuclear matter. © 2013 American Physical Society.

A simple method of room temperature phosphorescence is proposed for the determination of propranolol enantiomeric composition based on β-cyclodextrin as the chiral host and bromocyclohexane as the heavy atom. Enantiomeric complexes are formed upon binding of the propranolol enantiomer to β-cyclodextrin, and the sign of the resultant phosphorescence signals allows for the identity of the propranolol enantiomers configuration to be determined successfully.

A fluorescent off-on probe for H2S was exploited by coupling the azide-based strategy with the excited-state intramolecular proton transfer (ESIPT) sensing mechanism, which exhibits a considerably high fluorescence enhancement (1150-fold), an extremely low detection limit (0.78 nM), and a relatively fast response time (3-10 min) as well as excellent selectivity. © the Partner Organisations 2014.

Glucose regulated protein 78 (GRP78) has long been recognized as a molecular chaperone in the endoplasmic reticulum (ER) and can be induced by the ER stress response. Besides its location in the ER, GRP78 has been found to be present in cell plasma membrane, cytoplasm, mitochondria, nucleus as well as cellular secretions. GRP78 is implicated in tumor cell proliferation, apoptosis resistance, immune escape, metastasis and angiogenesis, and its elevated expression usually correlates with a variety of tumor microenvironmental stresses, including hypoxia, glucose deprivation, lactic acidosis and inflammatory response. GRP78 protein acts as a centrally located sensor of stress, which feels and adapts to the alteration in the tumor microenvironment. This article reviews the potential contributions of GRP78 to the acquisition of cancer hallmarks based on intervening in stress responses caused by tumor niche alterations. The paper also introduces several potential GRP78 relevant targeted therapies. © 2012 Elsevier B.V.

UDP-N-acetylglucosamine pyrophosphorylases (UAP) function in the formation of extracellular matrix by producing N-acetylglucosamine (GlcNAc) residues needed for chitin biosynthesis and protein glycosylation. Herein, we report two UAP cDNA's derived from two different genes (LmUAP1 and LmUAP2) in the migratory locust Locusta migratoria. Both the cDNA and their deduced amino acid sequences showed about 70% identities between the two genes. Phylogenetic analysis suggests that LmUAP1 and LmUAP2 derive from a relatively recent gene duplication event. Both LmUAP1 and LmUAP2 were widely expressed in all the major tissues besides chitin-containing tissues. However, the two genes exhibited different developmental expression patterns. High expression of LmUAP1 was detected during early embryogenesis, then decreased greatly, and slowly increased before egg hatch. During nymphal development, the highest expression of LmUAP1 appeared just after molting but declined in each inter-molting period and then increased before molting to the next stage, whereas LmUAP2 was more consistently expressed throughout all these stages. When the early second- and fifth-instar nymphs (1-day-old) were injected with LmUAP1 double-stranded RNA (dsRNA), 100% mortality was observed 2 days after the injection. When the middle second- and fifth-instar nymphs (3- to 4-day-old) were injected with LmUAP1 dsRNA, 100% mortality was observed during their next molting process. In contrast, when the insects at the same stages were injected with LmUAP2 dsRNA, these insects were able to develop normally and molt to the next stage successfully. It is presumed that the lethality caused by RNAi of LmUAP1 is due to reduced chitin biosynthesis of the integument and midgut, whereas LmUAP2 is not essential for locust development at least in nymph stage. This study is expected to help better understand different functions of UAP1 and UAP2 in the locust and other insect species.

Sulfur dioxide (SO2) supplies the basic sulfur element to promote plant growth, yet at the same time it is a harmful air pollutant. Currently, the mechanisms of plant adaptation to SO2 stress are largely unknown. Pathways of SO2 metabolism, a range of networks of interacting regulatory signals and defense mechanisms triggered in resistance to SO2 stress, have not yet been clarified. We performed transcriptome analysis of Arabidopsis plants fumigated with 30 mg m(-3) SO2 for 72 h and untreated controls using microarrays. This identified 2,780 significantly up- or down-regulated genes in plants response to SO2 stress, indicating a possible genome-scale reprogramming of the transcriptome. Significant changes in the transcript abundance of genes that participated in SO2 metabolic pathways indicated that numerous sulfites were involved in sulfur assimilatory pathways directly and away from sulfite oxidative pathways. Furthermore, the up-regulation of components involved in reactive oxygen species generating and scavenging pathways demonstrated altered redox homeostasis. Transcripts encoding key components in nitric oxide biosynthesis pathways were simultaneously up-regulated by SO2 exposure. In addition, transcripts associated with putative biotic stress were also up-regulated. Therefore, SO2 evokes a comprehensive reprogramming of metabolic pathways, consistent with up-regulation of transcripts involved in tolerance and defense mechanisms, in Arabidopsis.

The paper first introduces the basic problems of author bibliographic coupling including the relationship between author bibliographic coupling and document bibliographic coupling as well as the three calculation methods of author coupling strength, namely, simple method, minimum method and combined method. Next I choose a small sample of authors in Chinese library and information science (LIS) as the research objects to have a comparative analysis of three types of author coupling strength algorithms (the data source is from the Chinese Social Sciences Citation Index (CSSCI)). The result shows that the minimum method is the most appropriate one to calculate the author coupling strength. Then a large sample of authors is chosen to analyze the intellectual structure of Chinese LIS. The result shows that author bibliographic coupling analysis (ABCA) can discover the intellectual structure of a discipline better. It is also found that compared with author cocitation analysis (ACA), ABCA has the advantage that it not only can discover the intellectual structure of a discipline more comprehensively and concretely but also can reflect the research frontier of the discipline. Finally, some practical problems that arise during this research are discussed. © 2012 Elsevier Ltd.

In this paper we discuss the blow-up for classical solutions to the following class of parabolic equations with Robin boundary condition: {(b(u)) t=∇•(g(u) ∇u)+f(u)in Ω×(0,T),∂u/ ∂n +γu=0 on ∂Ω×(0,T),u(x,0)=h(x)≥0in Ω̄, where Ω is a bounded domain of ℝN(N≥2) with smooth boundary ∂Ω. By constructing some appropriate auxiliary functions and using a first-order differential inequality technique, we derive conditions on the data which guarantee the blow-up or the global existence of the solution. For the blow-up solution, a lower bound on blow-up time is also obtained. Moreover, some examples are presented to illustrate the applications. © 2013 Elsevier Ltd. All rights reserved.
