Design of ternary full-adder and full-subtractor using pseudo NCNTFETs
Now-a-days, the binary logic system has intensified by scaling the field effect transistor (FET). However, due to the effectiveness of scaling the FET, ternary logics became more popular. Out of numerous ternary logic devices, carbon nanotube (CNT) FET (CNTFET) is considered a good candidate over silicon FETs. Hence, in this study, ternary schematics are developed based on Pseudo N-type CNTFETs. The ternary basic designs such as standard ternary inverter (STI), AND and OR gates are presented. Then, using the proposed basic logic gates, the complex designs such as full adder and full subtractor are also proposed. The HSPICE simulator is utilized to design proposed circuits and analyze different performance parameters. The performance such as delay, power and power delay product (PDP) are analyzed for the proposed circuits. Moreover, the proposed schematics performances are also compared to complementary schematics. It investigated that Pseudo N-type CNTFET schematics improved the overall performance on an average up to 65.82% over the complementary ternary circuits

Not AvailableThe eastern Himalayas, one of the important hotspots of global biodiversity, have
a rich diversity of wild edible fruit trees. The fruits of these tree species have
been consumed by the tribal people since time immemorial. However, there
is limited information available on the biochemical and antioxidant properties
of the fruits. Therefore, the present investigation was undertaken to study the
physico-chemical and antioxidant properties of the nine most important wild
fruit trees. Among the species, Pyrus pashia had the maximum fruit weight
(37.83 g), while the highest juice (43.72%) and pulp content (84.67%) were noted
in Haematocarpus validus and Myrica esculenta, respectively. Maximum total
soluble solids (18.27%), total sugar (11.27%), moisture content (88.39%), ascorbic
acid content (63.82 mg/100 g), total carotenoids (18.47 mg/100 g), and total
monomeric anthocyanin (354.04 mg/100 g) were recorded in H. validus. Docynia
indica had the highest total phenolic content (19.37 mg GAE/g), while H. validus
recorded the highest total flavonoids and flavanol content. The antioxidant
activities of the different fruits ranged from 0.17 to 0.67 IC50 for DPPH activity and
3.59–13.82 mg AAE/g for FRAP. These fruits had attractive pigmentation of both
pulp and juice and were a good potential source for the extraction of natural
edible color in the food industry. The fruits also possess high market prices;
Prunus nepalensis fetched 141.5 per tree. Therefore, these fruits are
rich sources of antioxidants, pigments and have a high market value for livelihood
