Suppression of quantum dissipation: a cooperative effect of quantum squeezing and quantum measurement.

The ability to isolate a quantum system from its environment is of fundamental interest and importance in optical quantum science and technology. Here we propose an experimentally feasible scheme for beating environment-induced dissipation in an open two-level system coupled to a parametrically driven cavity. The mechanism relies on a novel, to the best of our knowledge, cooperation between light-matter coupling enhancement and frequent measurements.

[Effect of zinc on immune function in mice spleen lymphocytes].

Objective: In order to study the effects of different levels of zinc nutrition status on the immune function of mice spleen lymphocytes.

Methods: The experiment included two periods: zinc depleted period and repletion period. In the depleted period, mice were divided into 3 dose groups: zinc deficient group (ZD, 5.

[Effect of zinc on thymulin level in mice].

Objective: In order to investigate the roles of the different levels of zinc nutrition status on the thymulin of the mice.

Methods: The experiment included two periods: zinc depleted period and repletion period. In the depleted period, mice were divided into 3 dose groups: zinc deficient group (ZD, 5.

[Capillary zone electrophoresis for determination of thymulin in human plasma].

Aim: To establish a capillary zone electrophoresis (CZE) method for determination of thymulin in human blood plasma. Thymulin is a nonapeptide produced by the thymic epithelium.

Methods: The uncoated capillary used was 75 microns ID x 57 cm (50 cm effective length).
