DatalogMTL is a powerful extension of Datalog with operators from metric temporal logic (MTL), which has received significant attention in recent years. In this paper, we investigate materialisation-based reasoning (a.k.a. forward chaining) the context programs and datasets bounded intervals, where partial representations canonical model are obtained through successive rounds rule applications....

since 2005 a new powerful invariant of an algebra has emerged using the earlier work of horvath, hethelyi, kulshammer and murray. the authors studied morita invariance of a sequence of ideals of the center of a nite dimensional algebra over a eld of nite characteristic. it was shown that the sequence of ideals is actually a derived invariant, and most recently a slightly modied version o...

duffing harmonic oscillator is a common model for nonlinear phenomena in science and engineering. this paper presents he´s energy balance method (ebm) for solving nonlinear differential equations. two strong nonlinear cases have been studied analytically. analytical results of the ebm are compared with the solutions obtained by using he´s frequency amplitude formulation (faf) and numerical solu...

Thyrotoxic hypokalemic periodic paralysis is an uncommon complication of thyrotoxicosis, characterized by attacks of generalized muscular weakness associated with hypokalemia in patients with hyperthyroidism, most frequently with Graves-Basedow disease. Treatment with antithyroid drugs and potassium supplements reversed the symptoms and the episodes of acute muscular weakness did not reappear.

An interesting case of familial periodic paralysis came under my care quite recently and incidentally illustrated the hereditary nature of the disease. As the condition is so rare, a resume of the main features of the disease may be given. The disease is seldom seen; only 200 cases have been reported so far. It is characterized by a temporary flaccid paralysis of the muscles of the extremities ...
