The global spread of carbapenem-resistant Klebsiella pneumoniae(CRKP)has become a major healthcare burden because of the limited therapeutic options and poor prognosis,and this situation gets worse among patients admitted to intensive care unit(ICU).[1]CRKP can cause a range of infections,including pneumonia,urinary tract infection(UTI),and bloodstream infection(BSI).BSI is one of the most serious infections caused by CRKP and associated with high mortality ranging from 39%to 82%.[2]BSI due to CRKP could be primary infection or secondary infection that originated from primary infections in the lungs or bladder,and 50%of CRKP-BSIs originated from primary infections in the lungs.[3]Although previous studies have explored several risk factors for CRKP infections,the association between CRKP pneumonia and the development of secondary CRKP-BSI was not fully revealed thus *** aim of this study was to predict risk factors of 28-day mortality and the development of secondary CRKP-BSI in ICU-acquired pneumonia caused by CRKP.

Dear Editor,This letter presents a joint probabilistic scheduling and resource allocation method(PSRA) for 5G-based wireless networked control systems(WNCSs). As a control-aware optimization method, PSRA minimizes the linear quadratic Gaussian(LQG) control cost of WNCSs by optimizing the activation probability of subsystems, the number of uplink repetitions, and the durations of uplink and downlink phases. Simulation results show that PSRA achieves smaller LQG control costs than existing works.

Microstructure,texture,and mechanical properties of the extruded Mg-2.49Nd-1.82Gd-0.2Zn-0.2Zr alloy were investigated at different extrusion temperatures(260 and 320℃),extrusion ratios(10:1,15:1,and 30:1),and extrusion speeds(3 and 6 mm/s).The experimental results exhibited that the grain sizes after extrusion were much finer than that of the homogenized alloy,and the second phase showed streamline distribution along the extrusion direction(ED).With extrusion temperature increased from 260 to 320℃,the microstructure,texture,and mechanical properties of alloys changed *** dynamic recrystallization(DRX)degree and grain sizes enhanced as the extrusion ratio increased from 10:1 to 30:1,and the strength gradually decreased but elongation(EL)*** the extrusion speed increased from 3 to 6 mm/s,the grain sizes and DRX degree increased significantly,and the samples presented the typical-rare-earth(RE)*** alloy extruded at 260℃ with extrusion ratio of 10:1 and extrusion speed of 3 mm/s showed the tensile yield strength(TYS)of 213 MPa and EL of 30.6%.After quantitatively analyzing the contribution of strengthening mechanisms,it was found that the grain boundary strengthening and dislocation strengthening played major roles among strengthening *** results provide some guidelines for enlarging the industrial application of extruded Mg-RE alloy.
