Two general models with hierarchical and almost degenerate neutrino masses, which are able to explain the solar and atmospheric anomalies are investigated. We show how neutrinoless double beta decay experiments discern Dirac and Majorana natures of neutrinos. The strongest result is, that almost degenerate neutrinos with masses above 0.22 eV combined with the SMA MSW must be Dirac particles. In...

By adding copper to increase the performance, Ni-Ti-Cu Shape Memory Alloy (SMA), has been widely used in field of engineering recent years. A thermodynamic constitutive model for SMA considering different contents is established this work. Numerical results two contents, as examples, are compared with experimental verify accuracy theoretical Based on verified model, effects content mechanical p...

abstract objective autosomal recessive spinal muscular atrophy (sma) is, after cystic fibrosis, the second most common fatal monogenic disorder and the second most common hereditary neuromuscular disease after duchenne dystrophy. the disease is characterized by degeneration of anterior horn cells leading to progressive paralysis with muscular atrophy. depending on the clinical type (werdnig- ho...

Spinal muscular atrophy (SMA) is a genetic disorder which affect nervous system and is characterized with progressive distal motor neuron weakness. The survival motor neuron (SMN) protein level reduces in patients with SMA. Two different genes code survival motor neuron protein in human genome. Skeletal and intercostal muscles denervation lead to weakness, hypotony, hyporeflexia, respiratory fa...

T his paper investigates the asymmetric behavior of inflation. We use logistic smooth transition autoregressive (LSTAR) model to characterize the regime-switching behavior of Iran’s monthly inflation during the period May 1990 to December 2013. We find that there is a triple relationship between the inflation level, its fluctuations and persistence. The findings imply that the behavi...

The Iranian poultry sector has experienced many significant structural changes in recent years. Such changes may have influenced price dynamics and transmission of shocks through marketing channels especially on retail markets. This paper investigate price transmission, threshold behavior and asymmetric adjustment in poultry sector of Ardebil (AR), east Azerbaijan (EA) and west Azerbaijan (WA) ...

In this paper, the superelastic shape memory alloy (SMA) slit damper system as an alternative design approach for steel structures is intended to be evaluated with respect to inelastic behavior simulated by refined finite element (FE) analyses. Although the steel slit dampers conventionally used for aseismic design are able to dissipate a considerable amount of energy generated by the plastic y...
