    摘要： An entrainment-based mechanical ventilator may be initially set to approximate the patient's spontaneous respiratory frequency, enabling the patient to entrain to the ventilator if the ventilator frequency matches the patient's spontaneous breathing frequency or is within a reasonable range from it. If the preset frequency of the ventilator is set too high or too low from the spontaneous frequency, the patient will fall out of phase and “fight” the ventilator. The ventilator phase relative to the patient's breathing effort indicates the difference between the ventilator frequency and spontaneous frequency. Based on the phase difference, a closed-loop control mechanism may continuously adjust the ventilator frequency to match the patient breathing frequency until the phase shift is within a preset limit. Patient-ventilator entrainment will occur when the ventilator frequency is within a certain range from the patient breathing frequency.

    摘要翻译： 可以最初设置基于夹带的机械呼吸机以接近患者的自发呼吸频率，如果呼吸机频率与患者的自发呼吸频率相匹配或者在患者的自发呼吸频率的合理范围内，则患者能够夹带呼吸机。 如果呼吸机的预设频率从自发频率设置得太高或太低，患者将脱离相位并“通气”呼吸机。 呼吸机相位相对于患者的呼吸努力表明呼吸机频率与自发频率之间的差异。 基于相位差，闭环控制机构可以连续调节呼吸机频率以匹配患者呼吸频率，直到相移在预设限制内。 当呼吸机频率在患者呼吸频率的一定范围内时，将发生患者呼吸机夹带。

    摘要： A method for controlling an engine to reduce vehicle shuffle mode vibration during mode transition. The engine includes multiple cylinders, each with at least one electrically actuated valve, and the engine operates in a first mode having a first number of firing cylinders and a second mode having a second number of firing cylinders. The method comprises transitioning the engine from operating in the first mode to the second mode; adjusting at least a valve timing or lift of one of a last cylinder to be fired in said first mode and a first cylinder to be fired in said second mode to temporarily adjust a cylinder torque and thereby reduce vehicle shuffle mode vibration.

    摘要： A low-power laser and arc hybrid welding method includes the steps of matching laser pulses with arc phases, and inducing compress arcs by the laser pulses. A laser peak pulse is triggered from half of the positive half-wave to half of the negative half-wave of alternating arc current. The sum of laser peak pulse width and laser basic pulse width is equal to the time width from a laser pulse triggered point to a negative half-wave end point of the alternating arc current. A welding device for carrying out the method is disclosed. An angle formed by the axis of a laser beam (1) and the vertical direction is in the range of −50°-50°. An angle formed by the axis of the laser beam (1) and the axis of an arc torch (2) is in the range of 20°-120°. Arc power density is adjusted minutely in the range of 103-105 by adjusting the alternating arc current, protrusion quantity of an electrode (3) and gas flow velocity of a nozzle. The method and the device can reduce the consumption and save the cost.

    摘要： The present invention relates to the biotechnology field, more particularly, to novel recombinant staphylokinase (RGD/KGD-Sak) derivatives and the preparation the thereof. The derivatives, have a low polymerizing ability, low immunogenicity and a bifunctionality of thrombolytics and anticoagulant. Based on the line, structural analysis of the monomer and dimer of recombinant staphylokinases and their biochemical properties, we designed two novel bifunctional staphylokinase molecular structures. Mutant genes were constructed by PCR site-directed mutagenesis which were then recombined with a prokaryotic vector and used to transform E. coli. Engineered strains with a high expression level were selected by screening and propagated by fermentation, followed by disruption of the cells, centrifugation to collect inclusion bodies, renaturation, and purification of RGD/KGD-SAK through a two-step method. After lyophilized, the polymerizing ability and immunogenicity of the products decreased significantly. The derivatives can not only activate fibrinogen to lyse thrombus, but also significantly inhibit the platelet aggregation induced by ADP, suggesting that they have the bifunctionality of thrombolytics and anticoagulant.
