Majorana neutrino signals at Belle-II and ILC
For some theoretical and experimental considerations, the relatively light
Majorana neutrinos at the GeV scale have been attracting some interest. In this
article we consider a scenario with only one Majorana neutrino , negligible
mixing with the active neutrinos , where the Majorana neutrino
interactions could be described in a model independent approach based on an
effective theory. Under such a framework, we particularly study the feasibility
of observing the with mass in the range 030 GeV via the process e^+ e^-
\to \nu N \to\gamma + \slashed E in the future Belle-II and ILC experiments.
The results show that it is unpromising for Belle-II to observe the signal,
while ILC may easily make a discovery for the Majorana neutrino.Comment: 14 pages, 7 figures, 2 table
Expression of ENaC, SGK1 and Nedd4 isoforms in the cochlea of guinea pig
It has been demonstrated that the epithelial sodium channel (ENaC) may play critical roles in (re)absorbing Na+ from apical plasma membrane in various tissues and cells. Moreover, the serum glucocorticoid-inducible kinase 1 (SGK1) and the ubiquitin-protein ligase neural precursor cell-expressed, developmentally downregulated isoforms Nedd4 are involved in ENaC regulation in response to hormones such as aldosterone, vasopressin and insulin. The aim of the study was to investigate the cellular localizations of ENaC subunits, SGK1, and Nedd4 isoforms in the cochlea of guinea pig. Ten adult guinea pigs were sacrificed and their cochleas were collected. The expression patterns of ENaC subunits, SGK1 and Nedd4-2 isoforms in the guinea pig cochlea were studied by immunohistochemistry with the specific polyclonal rabbit antibodies against rat α-, β- and γ-ENaC, SGK1, Nedd4-1/2 and Nedd4-2. The results showed that all these proteins were extensively expressed in various regions of the cochlea. They were found in the spiral ligament, organ of Corti, spiral limbus, spiral ganglion and Reissner’s membrane with different staining patterns. The results indicated that a Na+ transport system may exist in the cochlea of guinea pig consisting of ENaC, SGK1 and Nedd4, which may work in concert to transport Na+ and to maintain homeostasis in inner ear as it does in other epithelia
Bis(1-adamantylammonium) tetrachloridocobaltate(II)
The CoII atom in the title salt, (C10H18N)2[CoCl4], exists in a tetrahedral coordination geometry. The asymmetric unit has two cations that lie on different special positions of site symmetry m; the anion lies on another special position of site symmetry m
