In the title compound, C(11)H(18)N(4)O(2)S(2), the dithiol-ane ring displays an envelope conformation, the tetra-hydro-pyrimidine ring has a conformation that is between half-chair and screw-boat, and the imidazole ring is essentially planar (r.m.s. deviation = 0.0017 Å). No significant directional inter-molecular inter-actions are present in the structure.

It is well known that the best equivariant estimator of a variance covari-ance matrix of multivariate normal distribution with respect to the full ane group of transformation is not even minimax. Some minimax estimators have been proposed. Here we treat this problem in the framework of a multivari-ate analysis of variance(MANOVA) model and give other classes of minimax estimators.

Accelerated life testing is awidely used tool for assessing the reliability of product components and materials. This paper is ituated in the world of planning such experiments. More specifically, ane w method to plan type I singly censored reliability e xperiments with variable test times will be conside red. A case study is performed in order to illustrate th e method.

OBJECTIVE To describe clinical features of epilepsy secondary to Malformation of Cortical Development (MCD) in a series of adult patients. MATERIALS AND METHODS We searched our database for all cases with confirmed epilepsy and MCD and included in the study only those with complete data. Mean age, sex, age at seizure onset (ASO), seizure types, abnormal neurological exam (ANE), mental retarda...

Application of sufficient lateral current to a heavy metal (HM) can switch the perpendicular magnetization orientation an adjacent ferromagnetic layer through spin–orbit torques (SOTs). The choice HM and its arrangement plays major role for SOT induced switching in magnetic heterostructures. Generally, thin Ta is used as underlayer better adhesion smoothness layer. Here, we show that addition a...

Abstract Prolonged drought periods cause a cascade of biochemical alterations in plants and lead to reduction plant growth crop productivity. Seaweed extracts are category biostimulants that effective alleviating stress on plants. However, the effect seaweed attenuating negative impact Faba bean ( Vicia faba L .) under arid semi-arid conditions has received little attention. This study was cond...

Magnetic anisotropies have key role to taylor magnetic behavior in ferromagnetic systems. Further, they are also essential elements manipulate the thermoelectric response Anomalous Nernst (ANE) and Longitudinal Spin Seebeck systems (LSSE). We propose here a theoretical approach explore of on magnetization noninteracting multidomain The curves calculated from modified Stoner Wohlfarth model for ...
