Abstract: Some embodiments of the disclosure provide an air intake bypass recirculation structure with adjustable air entraining amount and controllable broadband noise which includes main body of the air intake bypass recirculation structure and an air entraining amount adjusting structure. In some examples, an air intake bypass recirculation cavity is formed in the main body of the air intake bypass recirculation structure. An air inlet of an air intake pipe and an air outlet of the air intake pipe are formed in two ends of the main body of the air intake bypass recirculation structure respectively. An airflow inlet of the air intake bypass recirculation structure and an airflow outlet of the air intake bypass recirculation structure are formed in the inner side of the main body of the air intake bypass recirculation structure. The air entraining amount adjusting structure is arranged in the air intake bypass recirculation cavity.

Abstract: This disclosure relates to techniques for multi-RAT and DSDA capable wireless devices to handle frame blanking in a wireless communication system. A wireless device may establish wireless links according to a first radio access technology and a second radio access technology. The wireless device may determine to perform transmit and receive blanking for one or more antennas of the wireless device for the first radio access technology to perform sounding reference signal transmissions for the second radio access technology based at least in part on a band combination for the wireless links. The wireless device may determine a modification to channel state feedback reporting for the first radio access technology based at least in part on the transmit and receive blanking. The wireless device may perform channel state feedback reporting using the determined modification.

Abstract: Diesel fuels or blending stocks having excellent lubricity, oxidative stability and high cetane number are directly produced from synthesis gas over activated carbon supported cobalt based Fischer-Tropsch catalyst under the condition of temperature within the range of 120 to 400° C., reaction pressure within the range of 0.5 to 10.0 MPa, volume hourly space velocity of a mixture of hydrogen and carbon monoxide within the range of 100 to 5000, the mole ratio of hydrogen to carbon monoxide within the range of 1 to 4. Diesel fuels containing at least 95 wt % paraffins with an iso to normal ratio of about 0.03 to 0.3, <50 ppm (wt) of sulfur and nitrogen, less than about 2 wt % unsaturates, and about 0.001 to less than 0.3 wt % oxygen were obtained by separating the Fischer-Tropsch product into a lighter (180 to 245 ° C. fraction) and heavier fractions (245 to 380° C. fraction) utilizing a rough flash, and combining the 180 to 245° C. portion of the lighter product with the 245 to 380° C.

Abstract: Diesel fuels or blending stocks having high cetane number are produced from non-shifting Fischer-Tropsch processes, which directly convert carbon monoxide and hydrogen to diesel distillates over activated carbon supported cobalt based Fischer-Tropsch catalysts. The activated carbon supported cobalt based catalysts comprise a substantially high dispersion of at least one of a zirconium component, an cerium component, a ruthenium component or a potassium component in porous carbon and elemental cobalt either deposited thereon or substantially uniformly dispersed therein, wherein the concentration of activated carbon in the catalyst is from about 20 to about 90 percent by weight, based on the weight of the catalyst, the concentration of elemental cobalt in the catalyst is from about 4 to about 50 percent by weight, based on the weight of the catalyst, the total concentration of the zirconium component, the cerium component, or a combination thereof in the catalyst is from about 0.
