The isolation of compounds 1 and 2, respectively from two unrelated plants [a Pandanus (Pandanaceae) and a Myrmecodia (Rubiaceae)] is presented. According to the Nuclear Magnetic Resonance (NMR) spectroscopy, both biomolecules could be a triterpene. The NMR data from P. tectorius' phytosterol was compared, where a mixture of stigmasterol:β-sitosterol (2:1) was reported. However, the signals for an...
For many years the only known passive circuit elements were resistor, inductor and capacitor. In 1971, Leon Chua showed using argument that there should exist another passive element which he named memristor. It is basically a resistor whose resistance increases when current flows through it from one direction and decreases when current flows from the other direction. After 37 years researchers of...
In this paper, we have shown a new design for double qutrit multiplier for quantum computer. This multiplier can be an essential part of quantum arithmetic logic unit (ALU). This proposal is based on ion-trap scheme of quantum computer, which is practically realizable using current technology.
For various reasons in recent years the interest in building quantum computers has increased gradually. To do the calculations in quantum computer we need quantum arithmetic logic unit (ALU). The building block of quantum ALU is quantum adder. In quantum computer multivalued logic is possible. In this paper a generalized circuit has been proposed to build odd base multivalued quantum half adder. A...
Recent research has shown that while Lewy body dementia. (LBD) may be the second most common form of dementia, it is difficult to confirm the disease before autopsy. Patients with LBD share many clinical signs and symptoms with patients diagnosed with Alzheimer's disease (AD), making it difficult to differentiate between the two diseases in patients who are still living. Still, our purpose in this...
