Abstract: Provided is an electric cable driving mechanism having a self-return function. The electric cable driving mechanism includes a housing assembly, an electric motor, a three-stage transmission mechanism and a multifunctional nut, the three-stage transmission mechanism includes a coil spring assembly, the electric motor is fixed to the housing assembly, and the three-stage transmission mechanism and the multifunctional nut are mounted in the housing assembly; and the multifunctional nut includes two cable mounting grooves and is in transmission connection to the electric motor by means of the three-stage transmission mechanism. According to the electric cable driving mechanism having a self-return function of the present disclosure, the three-stage transmission mechanism is used, and outputs a larger force compared with two-stage transmission; and a split multifunctional screw rod is easy to mount, such that mounting of a coil spring during assembly is prevented from scratching the screw rod.

Abstract: A zircon ID-TIMDS Pb isotope determination method by multiple ion counters with a dynamic multi-collection protocol is provided. Compared with a commonly used multi-ion counter static determination method, the method provided by the present invention completely eliminates influences of gain differences of the different ion counters on determination results of Pb isotopes. Compared with a conventional single-ion counter determination method with five times of peak-jumps, the method provided by the present invention can obtain all of Pb isotope ratios with two times of peak-jumps, which increases the collection efficiency of Pb isotope ion beams and decreases influences of ion beam stability on Pb isotope analysis results.

Abstract: There is provided a method of sensitising a eukaryotic cell to ultrasound stimulation, said method comprising increasing the mechano-sensitivity of a transmembrane ion channel of the cell to ultrasound by introducing a plurality of entire exogenous gas vesicles proximal to the surface of the cell.

Abstract: A suitcase combination lock includes a locking element and a password element for controlling the movement of the locking element. Both ends of the password element have the locking element, and a swingable adapter installed between the two locking elements, and the two locking elements are connected to both ends of the adapter respectively, so that the two locking elements can jointly drive the adapter to swing, and the two locking assemblies are linked with each other. The two locking assemblies can move outwardly or inwardly at the same time. If the password is correct, and a position of the suitcase with one of the locking elements is hit, a single locking element cannot be moved easily to prevent a lock hook of the locking element from being rotated, and prevent a lock failure of the locking assembly.

Abstract: In an aspect of the present disclosure there is provided a method for reversibly stimulating neuronal cells, said method comprising activating mechanosensitive ion channels of neuronal cells expressing said channels by exposing said cells to an ultrasound stimulus.
