Abstract: The EI Ni?/La Ni?a-Southern Oscillation (ENSO) is an interannual phenomenon involved in the tropical Pacific Ocean--atmosphere interactions. In this paper, an asymptotic method of solving the nonlinear equation for the ENSO model is created. And based on a class of oscillator of the ENSO model, the approximate solution of a corresponding problem is studied by employing the method of homotopic mapping. It is proved from the results that the homotopic method can be used for analysing the sea surface temperature anomaly in the equatorial eastern Pacific and the thermocline depth anomaly of the atmosphere--ocean oscillation for the ENSO model.
Crossover from skin-mode to proton-neutron-mode in $E1$ excitations of neutron-rich nuclei  [PDF]

Physics , 2012, DOI: 10.1103/PhysRevC.87.034302
Abstract: Character of the low-energy $E1$ excitations is investigated by analyzing transition densities obtained from the RPA calculations in the doubly-magic nuclei. We propose a decomposition method of the $E1$ excitations into the $pn$ mode (i.e. oscillation between protons and neutrons) and the skin mode (oscillation of the neutron skin against the inner core) via the transition densities, by which their mixing is handled in a straightforward manner. Crossover behavior of the $E1$ excitations is found, from the skin mode at low energy to the $pn$ mode at higher energy. The ratio of the skin-mode strength to the full strength turns out to be insensitive to nuclide and to effective interactions in the energy region of the crossover. Depending on the excitation energy, the observed low-energy $E1$ excitations are not necessarily dominated by the skin mode, as exemplified for $^{90}$Zr. fied for $^{90}$Zr.

Cleft lip and palate in southwestern Iran : An epidemiologic study of live births.  [cached]
Rajabian Mohammad,Aghaei Shahin
Annals of Saudi Medicine , 2005,
Abstract: Background: Cleft lip with or without cleft palate (CL/P), is the most common congenital anomaly in the head and neck worldwide. We stud-ied the prevalence of cleft lip (CL) and palate (CP) in Shiraz, which is located in southwestern Iran. Methods: Data was collected from the teaching hospitals of the Shiraz University of Medical Sciences. Records of 147 608 consecutive live births delivered in three hospitals during the 10 years from November 1993 to November 2003 were reviewed. Results: One hundred nineteen cases of CL/P or CP alone were reg-istered for a prevalence of 0.80 per thousand live births. The overall male/ female ratio was 1.25. The male/female ratio was 1.22 in the CL patients and 1.58 in the CL/P patients. A male predominance was obvi-ous in both groups. Conclusion: This study shows that the prevalence rate of CL and CP in southwestern Iran is closer to the low prevalence reported in African countries and is lower than the prevalence reported in previous reports in Caucasians.
Relation of E1 pygmy and toroidal resonances  [PDF]
V. O. Nesterenko,A. Repko,P. -G. Reinhard,J. Kvasil
Physics , 2014, DOI: 10.1038/ncomms8382
Abstract: A possible relation of the low-lying E1 (pygmy resonance) and toroidal strengths is analyzed by using Skyrme-RPA results for the strength functions, transition densities and current fields in $^{208}$Pb. It is shown that the irrotational pygmy motion can appear as a local manifestation of the collective vortical toroidal dipole resonance (TDR) at the nuclear surface. The RPA results are compared to unperturbed (1ph) ones.
Radiative E1 decays of X(3872)  [PDF]

Physics , 2010, DOI: 10.1016/j.physletb.2011.02.014
Abstract: Radiative E1 decay widths of $\rm X(3872)$ are calculated through the relativistic Salpeter method, with the assumption that $\rm X(3872)$ is the $\chi_{c1}$(2P) state, which is the radial excited state of $\chi_{c1}$(1P). We firstly calculated the E1 decay width of $\chi_{c1}$(1P), the result is in agreement with experimental data excellently, then we calculated the case of $\rm X(3872)$ with the assignment that it is $\chi_{c1}$(2P). Results are: ${\Gamma}({\rm X(3872)}\rightarrow \gamma \sl J/\psi)=33.0$ keV, ${\Gamma}({\rm X(3872)}\rightarrow \gamma \psi(2S))=146$ keV and ${\Gamma}({\rm X(3872)}\rightarrow \gamma \psi(3770))=7.09$ keV. The ratio ${{\rm Br(X(3872)}\rightarrow\gamma\psi(2{\rm S}))}/{{\rm Br(X(3872)}\rightarrow \gamma {\sl J}/\psi)}=4.4$ agrees with experimental data by BaBar, but larger than the new up-bound reported by Belle recently. With the same method, we also predict the decay widths: ${\Gamma}(\chi_{b1}(1\rm P))\rightarrow \gamma \Upsilon(1\rm S))=30.0$ keV, ${\Gamma}(\chi_{b1}(2\rm P))\rightarrow \gamma \Upsilon(1\rm S))=5.65$ keV and ${\Gamma}(\chi_{b1}(2\rm P))\rightarrow \gamma \Upsilon(2S))=15.8$ keV, and the full widths: ${\Gamma}(\chi_{b1}(1\rm P))\sim 85.7$ keV, ${\Gamma}(\chi_{b1}(2\rm P))\sim 66.5$ keV.

Abstract: Factors that determine genetic structure of species in southwestern China remain largely unknown. In this study, sequences of two mitochondrial genes (COI and cyt b) were determined to investigate the phylogeography and demography of Babina pleuraden, a pond frog endemic to southwestern China. A total of 262 individuals from 22 populations across the entire range of the species were collected. Our results indicate that B. pleuraden comprises five well-supported mitochondrial lineages roughly corresponding to five geographical areas. The phylogeographic structure of B. pleuraden has been shaped primarily by the unique regional responses of the Yunnan Plateau to the rapid uplift of the Qinghai-Tibetan Plateau occurred c. 2.5 Mya (B phrase of Qingzang Movement) and climatic oscillation during middle Pleistocene (c. 0.64–0.36 Mya), rather than by the paleo-drainage systems. The present wide distribution of the species has resulted from recent population expansion (c. 0.053–0.025 Mya) from multiple refugia prior to the Last Glacial Maximum, corresponding to the scenario of “refugia within refugia”.

Abstract: Mass spectrometry and in silico sequence analysis were used to identify phosphate sites on the BPV E1 protein and kinases that may recognize these sites. Five new and two previously known phosphorylation sites were identified. A phosphate site map was created and used to develop a general model for the role of phosphorylation in E1 function.Mass spectrometric analysis identified seven phosphorylated amino acids on the BPV E1 protein. Taken with three previously identified sites, there are at least ten phosphoamino acids on BPV E1. A number of kinases were identified by sequence analysis that could potentially phosphorylate E1 at the identified positions. Several of these kinases have known roles in regulating cell cycle progression. A BPV E1 phosphate map and a discussion of the possible role of phosphorylation in E1 function are presented.Papillomaviruses infect epithelial cells of cutaneous or mucosal origin in a variety of vertebrate hosts. An infection is established in the basal layer of the epithelium, and a complex viral life cycle is carried out, dependent on the differentiation state of the host cell [1-3]. Upon entry into a basal epithelial cell, the infecting genome is transiently amplified to approximately 50 to 200 copies, establishing a latent infection. As latently infected cells divide, the viral genomes are replicated on average once per cell cycle to maintain this low genome copy number [4,5]. Minimal viral gene expression is observed during the latent period. As progeny cells migrate towards the epithelial surface, a differentiation pathway is triggered, leading to changes in viral gene expression, genome amplification, and assembly of progeny virions.The papillomavirus genome must undergo three distinct modes of DNA replication during the course of an infection: transient amplification immediately upon infection; regulated replication during latency to maintain a constant copy number; and vegetative replication to amplify copy number prior to vir
