Abstract: The present invention relates to a yeast gene ScFIT3 for regulating and controlling cadmium resistance of an organism and an application thereof. The yeast gene ScFIT3 for regulating and controlling the cadmium resistance of the organism has a nucleotide sequence as shown in SEQ ID NO.1. The present invention discloses, for the first time, the application of the yeast gene ScFIT3 in enhancing cadmium resistance of the organism. The yeast gene ScFIT3 is linked to an expression vector and transformed into a budding yeast, thereby completing construction of a cadmium-resistant yeast. The growth of the budding yeast transformed with the yeast gene ScFIT3 is significantly superior to that of a wild-type budding yeast, indicating that the budding yeast transformed with the yeast gene ScFIT3 has good resistance to cadmium stress, significantly enhances a capability of resisting heavy metal cadmium, and reduces accumulation and absorption of cadmium.

Abstract: The present invention disclosed a method for calculating an oscillation damping ratio of a power grid, and relates to the field of power system operation and control. When a power system oscillates, an oscillation period, two oscillation extreme points, and an oscillation direct current component start to be detected. Then an oscillation decay time constant is calculated according to the two oscillation extreme points and the oscillation direct current component. The oscillation damping ratio is calculated through the oscillation decay time constant and the oscillation period. Compared with a conventional fitting method, the conventional fitting method cannot calculate and analyze the oscillation damping ratio in a cast that a complete oscillation waveform is not obtained. The method proposed by the present inventive patent may complete the calculation of the oscillation damping ratio in a case of obtaining 2 pieces of data, so as to accelerate the speed of calculation.

Abstract: An integrated method for clearance, collection and capture of internal pollutants and algae at the bottom of a lake include the following steps: selecting areas where the pollution level is high, and organic or inorganic particulate matter is prone to accumulation and carrying out trenching operations at the bottom of the lake to form a plurality of traps; and removing the sludge and algae inside the traps and clearing the sediment inside the traps, for subsequent internal pollution control when the surface-layer sludge on both sides of the traps almost fills up the traps. This method makes use of the hydrodynamic disturbances of waves formed by natural wind energy and lake currents to continuously transport sludge with a high pollution level and a small specific gravity and algae in the surface layer of the lake bottom, which are rich in organic debris, to artificially built traps.

Abstract: The present invention provides electronic systems, including device arrays, comprising functional device(s) and/or device component(s) at least partially enclosed via one or more containment chambers, such that the device(s) and/or device component(s) are at least partially, and optionally entirely, immersed in a containment fluid. Useful containment fluids for use in containment chambers of electronic devices of the invention include lubricants, electrolytes and/or electronically resistive fluids. In some embodiments, for example, electronic systems of the invention comprise one or more electronic devices and/or device components provided in free-standing and/or tethered configurations that decouple forces originating upon deformation, stretching or compression of a supporting substrate from the free standing or tethered device or device component.

Abstract: Origami- and Kirigami-inspired assembly of predetermined three-dimensional forms is presented in comprehensive theoretical and experimental studies, with examples of a broad range of topologies and material compositions. The resulting engineering options in the construction of functional 3D structures have important implications for advanced microsystem technologies.

Abstract: The present invention provides electronic circuits, devices and device components including one or more stretchable components, such as stretchable electrical interconnects, electrodes and/or semiconductor components. Stretchability of some of the present systems is achieved via a materials level integration of stretchable metallic or semiconducting structures with soft, elastomeric materials in a configuration allowing for elastic deformations to occur in a repeatable and well-defined way. The stretchable device geometries and hard-soft materials integration approaches of the invention provide a combination of advance electronic function and compliant mechanics supporting a broad range of device applications including sensing, actuation, power storage and communications.
