Unitarity violation in sequential neutrino mixing in a model of extra dimensions

We investigate the possibility of unitarity violation in the sequential neutrino mixing matrix in a scenario with extra compact spacelike dimensions. Gauge singlet neutrinos are assumed to propagate in one extra dimension, giving rise to an infinite tower of states in the effective four-dimensional theory. It is shown that this leads to small lepton-number violating entries in the neutrino mass matrix, which can violate unitarity on the order of one per cent.Comment: 16 pages, 2 table

Characteristics of cataract patients who underwent cataract surgery in H. L. Manambai Abdulkadir hospital Sumbawa

Background: Cataract is a clouding of the natural intraocular crystalline lens that can cause decrease in vision and may lead to blindness. Worldwide, cataracts are number one cause of preventable blindness. Cataract surgery is the most effective intervention regardless of its etiology. The purpose of this study was to obtain characteristics of cataract patients who underwent cataract surgery in H. L. Manambai Abdulkadir hospital Sumbawa based on cataract types, sex, age, comorbidities, initial visual acuity, and surgery methods. Methods: A quantitative study at H. L. Manambai Abdulkadir hospital Sumbawa. Consecutive, non-random sampling technique was used to recruit participants. This study enrolled 317 cataract patients who underwent cataract surgery. Results: Of the 317 patients, 172 (54.26%) were men, 301 (94.95%) senile cataract, 141 (44.48%) bilateral case, 210 (66.25%) initial visual acuity <3/60, 43 (13.56%) with diabetes mellitus. Two hundred and seventy eight (88.54%) underwent phacoemulsification surgery, with 303 (95.58%) experienced visual acuity improvement. Conclusions: Most of cataracts patients who underwent cataract surgery were men, most surgery were done by phacoemulsification method. Senile cataract and bilateral case are the most common case. Patients had visual acuity improvement after cataract surgery.

Diversity of Herbaceous Plant in the Utilization Block of Sumber Agung Tahura Wan Abdul Rachman Bandar Lampung

Diversity is a variety of species that are similarly formed and the abundance of a species. The purpose of this study is to determine the diversity and characteristics of herbaceous plants in Sumber Agung Resort Bandar Lampung Wan Abdul Rachman (WAR) forest park. The method used is a purposive sampling method at several points, done by direct observation using the Belt Transect method with plot size 1x1 m² with a distance between plot 100 m² then the picture of herbaceous plants taken as documentation material. The species is then taken for identification regarding some literature. Data analysis by measuring the parameters of vegetation using the analysis of density and frequency variables which then determine the Importance Value Index (INP). Observation of herbaceous plants was done by identifying and making herbarium. The results of the study are, there are 45 species of herbaceous plants that have been identified, consisting of 22 families. The highest density of herbaceous species that are found belongs to Asteraceae, Solanaceae, Araceae, Poaceae, Zingiberaceae, and Euphorbiaceae. Characteristics of herbaceous growth are influenced by air temperature, soil moisture, and soil pH. The highest Important Value Index (INP) in herbaceous plants belongs to Family Poaceae; Lophatherium gracile with an important value index (INP) 31.43%

Two-loop neutrino masses with large R-parity violating interactions in supersymmetry

We attempt to reconcile large trilinear R-parity violating interactions in a supersymmetric (SUSY) theory with the observed pattern of neutrino masses and mixing. We show that, with a restricted number of such interaction terms with the $\lambda'$-type couplings in the range (0.1-1.0), it is possible to forbid one-loop contributions to the neutrino mass matrix. This is illustrated with the help of a `working example' where an econnomic choice of SUSY parameters is made, with three non-vanishing and `large' R-parity violating terms in the superpotential. The two-loop contributions in such a case can not only generate the masses in the requisite order but can also lead us to specific allowed regions of the parameter space.Comment: Revised version, 25 pages, 16 figure
