Thermodynamic fingerprints of non-Markovianity in a system of coupled superconducting qubits

The exploitation and characterization of memory effects arising from the interaction between system and environment is a key prerequisite for quantum reservoir engineering beyond the standard Markovian limit. In this paper we investigate a prototype of non-Markovian dynamics experimentally implementable with superconducting qubits. We rigorously quantify non-Markovianity highlighting the effects of the environmental temperature on the Markovian to non-Markovian crossover. We investigate how memory effects influence, and specifically suppress, the ability to perform work on the driven qubit. We show that the average work performed on the qubit can be used as a diagnostic tool to detect the presence or absence of memory effects.Comment: 9 page

Comparison of Parameters of Lognormal Distribution Based On the Classical and Posterior Estimates

Lognormal distribution is widely used in scientific field, such as agricultural, entomological, biology etc. If a variable can be thought as the multiplicative product of some positive independent random variables, then it could be modelled as lognormal. In this study, maximum likelihood estimates and posterior estimates of the parameters of lognormal distribution are obtained and using these estimates we calculate the point estimates of mean and variance for making comparisons

Active flutter suppression of a cantilever plate at supersonic speeds

Modern high-speed aircrafts are flown using the fly-by- wire system. The d y n a m i c s of automatic flight control system interacts with aircraft's structural dynamics and aerodynamics to give rise to aero servo elastic problems. Such problems can be avoided using an active control system. AS a feasibility study, active flutter suppression of a cantilever plate wing was carried out. In this study it was demonstrated that the flutter Mach number of the cantilever wing can be increased by 12.5%

Eff ect of triazole compounds on induced changes in growth biomass and biochemical content of white radish (Raphanus sativus L.)

Radish (Raphanus sativus L.), belongs to the family Brassicaceae is an important vegetable crop and cultivated all over the India. The tuber of radish is used to prepare the salad and for the preparation of various health dishes. It is rich in vitamin ‘C’ and minerals. It is also used as medicinal properties such as currying liver disorders, jaundice, and various physiological disorders. In the present investigation, the effect of triazole compounds such as triadimefon (TDM) and hexaconazole (HEX) on radish. The plants were given separate treatment with 1 L of water solution containing 20/mg TDM and 1 L of water solution containing 20/mg HEX on 23, 35, and 53 days after sowing (DAS) by soil drenching method. The plants were harvested randomly on 30, 45, and 60 DAS for the determination of growth of tuber, shoot, and biochemical contents viz., starch, protein, and amino acid both in the control and triazole treated plants. From the results it is observed that the triazole treated plants showed pronounced effect in increasing the tuber fresh and dry biomass, protein, amino acid, and starch content in both shoot and tuber tissues of radish, whereas the shoot fresh and dry biomass were decreased when compared to control plants of radish

EVALUATION OF PROTEIN RELEASE RATE FROM MYCOPROTEIN - FUSARIUM VENENATUM BY CELL DISRUPTION METHOD

Objective: Single cell protein based on mycoprotein is now extensively used as human and animal feed in various parts of the world. It is used because of the high nutrient content particularly protein and the supply of protein is an essential criteria of utilization of mycoprotein. The present study is about evaluation of protein release rate from mycoprotein - Fusarium venenatum by cell disruption method. Methods: Fusarium venenatum was cultivated in Vogel's mineral medium and the separated biomass was subjected to lyophilization followed by grinding and sonication under different time periods to release the protein. Liberated protein was estimated by Lowry's method and the protein release rate was determined. Results: Maximum protein release rate constant 0.680 min was recorded in grinding with sonication. Conclusion: Protein release rate from mycoprotein – Fusarium venenatum by cell disruption method is the useful study to determine the optimal utilization of nutrient factors supplied by the mycoprotein to the consumers.Further studies will be helpful to determine the release profile with suitable animal model
