TL;DR: An in vitro 3D EndMT model is presented to understand the progress of the CAF generation by recapitulating the 3D tumor microenvironment in a microfluidic device and can serve as a powerful tool to validate exosomal components that could be further developed to anti-cancer drugs.

TL;DR: Owing to the high capacitance and excellent rate performance of SiC-N-MnO2 and AC, as well as the synergistic effects of the two electrodes, a constructed asymmetric supercapacitor exhibited superior electrochemical performance.
Abstract: In order to achieve high energy and power densities, a high-voltage asymmetric electrochemical supercapacitor has been developed, with activated carbon (AC) as the negative electrode and a silicon carbide–MnO2 nanoneedle (SiC–N-MnO2) composite as the positive electrode. A neutral aqueous Na2SO4 solution was used as the electrolyte. SiC–N-MnO2 was prepared by packing growing MnO2 nanoneedle crystal species in only one direction on the silicon carbide surface. AC was oxidized by thermal treatment in order to introduce oxygen-containing functional groups. Owing to the high capacitance and excellent rate performance of SiC–N-MnO2 and AC, as well as the synergistic effects of the two electrodes, a constructed asymmetric supercapacitor exhibited superior electrochemical performance. The optimized asymmetric supercapacitor could be cycled reversibly in the voltage range from 0 to 1.9 V, and it exhibited a specific capacitance of 59.9 F g−1 at a scan rate of 2 mV s−1 and excellent energy density and power density (30.06 W h kg−1 and 113.92 W kg−1, respectively) with a specific capacitance loss of less than 3.1% after 1000 charge–discharge cycles, indicating excellent electrochemical stability. These encouraging results show great potential in terms of developing energy storage devices with high energy and power densities for practical applications.

TL;DR: The results suggest that if employees can adjust aspects of their office work environment, this may increase their sense of personal control, reducing the effects of distractions, a frequent complaint in open offices.
Abstract: Statement of Relevance: The purpose of this study was to investigate whether perception of control over aspects of the physical environment reduces the previously documented negative effects of distraction in office workplaces on perceived job performance. This study analysed 384 questionnaires collected from employees in the corporate offices of three manufacturing companies in Michigan, USA. The role of a sense of personal control over physical environment features as a mediating influence between work attitudes and work outcomes was explored using structural equations modelling. The results showed that workers' sense of control over physical aspects of their work environment mediated the relationship between perceived distractions and perceived job performance. These results suggest that increasing perceptions of personal control over features of the physical work environment may serve to link work attitudes and work outcomes. Open-plan offices are common throughout the world, making this study relevan...

18 Sep 2000TL;DR: An efficient channel estimation technique for orthogonal frequency-division multiplexing (OFDM) systems with transmitter diversity using "comb-type" training symbols is proposed, reduced dramatically, compared with the previous minimum mean-squared error technique.
Abstract: We propose an efficient channel estimation technique for orthogonal frequency-division multiplexing (OFDM) systems with transmitter diversity. The proposed technique estimates uniquely all channel frequency responses needed in space-time coded OFDM systems using "comb-type" training symbols. The computational complexity of the proposed technique is reduced dramatically, compared with the previous minimum mean-squared error (MMSE) technique, due to the all the processing being done in the frequency-domain. Also, several other techniques for mitigating the random noise effect and tracking channel variation are discussed to further improve the performance of the proposed approach. The performances of the proposed approach are demonstrated by computer simulation for mobile wireless channels.
