  • Publication number: 20240118205
    Abstract: The invention provides a bacterial cellulose-based biosensor, including bacterial cellulose (BC) and a cell presenting a cellulose-binding module CBM2a on the surface. The cell is attached to BC through CBM2a. The cell expresses CBM2a by using pETDuet-tac as a vector. The pETDuet-tac is obtained by replacing two T7 promoters on the vector pETDuet by tac promoters, that is, an upstream first tac promoter and a downstream second tac promoter. The pETDuet-tac includes a gene encoding a fluorescent protein downstream of the first tac promoter and a gene encoding CBM2a presented on the surface downstream of the second tac promoter. By the BC-based biosensor, efficient and specific immobilization of cells on the BC matrix is enabled, the biological activity of cells is maintained, the fluorescence signal output is enhanced, and sufficient pores are provided for the entry and exit of a detected substance, thereby significantly improving the detection sensitivity.

  • Publication number: 20230298060
    Abstract: Methods, systems, and computer readable media for thermal load management of a collection of power consumers managed by an electric power aggregator. In some examples, a system includes a scheduling subsystem, implemented on one or more processors, configured for determining a plurality of cooling or heating control schedules for the collection of power consumers by forecasting one or more wholesale electricity price peaks. The system includes a control system implemented on one or more processors. The control system is configured for carrying out the cooling or heating control schedules at the individual consumer-level. The control system is configured for guaranteeing, for each power consumer of the collection of power consumers, a comfort constraint specified by a bilevel thermostat for the power consumer, wherein the comfort constraint comprises a lower level bound temperature and an upper bound temperature that the power consumer is willing to tolerate.

  • Patent number: 11454366
    Abstract: The present disclosure provides an automobile lamp lighting system, including a light source, a reflecting mirror, a light-shielding plate, and a lens. The lens includes a reflecting surface and a refracting surface opposite to the reflecting surface. When an external parallel light is incident into the lens, the external parallel light sequentially passes through the refracting surface for a first refraction, is reflected by the reflecting surface, passes through the refracting surface for a second refraction, exits the lens, and is converged to form a focal point. The reflecting mirror includes a near focal point and a far focal point, the light source is arranged at the near focal point, and the far focal point is located near the focal point of the lens. The light-shielding plate includes a light-shielding plate cut-off line located at the focal point of the lens.
