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
Intravitreous injection of Lucentis combined with argon laser photocoagulation for treatment of retinal macroaneurysm
AIM: To evaluate the clinical efficacy of intravitreous injection of Lucentis combined with argon laser photocoagulation on retinal macroaneurysm.<p>METHODS: A retrospective observation about intravitreous injection of Lucentis combined with argon laser photocoagulation was performed on 9 patients(9 eyes)with retinal macroaneurysms with macular edema between January 2011 and July 2013. Through the collection of clinical data in patients best-corrected visual acuity, change of the retinal macroaneurysm, optical coherence tomography and fluoresce in fundus angiography before therapy and 1 mouth,3 mouths after therapy, comparative analysis the changes in best-corrected visual acuity and central macular retinal thickness(CMT)between before and after treatment.<p>RESULTS: Followed for more than 3 months, all patients' best-corrected visual acuity were improved obviously, the difference was significant(<i>P</i><0.05); The patients' macular edema was obviously absorbed and the average CMT was significantly lower, the difference was significant(<i>P</i><0.05). In fundus fluorescein angiography, the neoplasia body was atrophied inordinately after 3 months of treatment.<p>CONCLUSION:Intravitreous injection of Lucentis combined with argon laser photocoagulation is effective and security to improving visual acuity of retinal macroaneurysms with macular edema
trans-Bis[4-amino-N-(pyrimidin-2-yl)benzenesulfonamidato]dipyridinenickel(II) hemihydrate
The asymmetric unit of the title compound, [Ni(C10H9N4O2S)2(C5H5N)2]·0.5H2O, contains the distorted octahedral trans-[Ni(sdz)2(py)2] (sdz is the sulfadiazine anion and py is pyridine) complex molecule and half of a water molecule. A three-dimensional network is generated by N—H⋯O and O—H⋯O hydrogen bonds and C—H⋯O interactions between the complex and the water molecules
