As the main byproduct of cotton production,cottonseed yields edible vegetable oil,ruminant feed,and industrial *** evaluated the individual and interactive effects of elevated air temperature and soil drought on cottonseed yield and nutritional quality using two cotton cultivars,Sumian 15(heat-susceptible)and PHY370 WR(heat-tolerant).The experiment was conducted under three levels of soil relative water content(SRWC):(75±5)%,(60±5)%and(45±5)%and two temperature regimes:ambient temperature(AT,31.0/26.4℃,mean daytime/night temperature)and elevated temperature(ET,33.4/28.9℃).Cottonseed yield,boll number,seed number,and single-seed weight were lower under combined ET and SRWC(45±5)%than either individual stress or combined stresses in comparison with the control treatment(SRWC(75±5)%under AT).Drought tended to increase oil content and reduce protein content,whereas ET showed almost the opposite *** the combination of ET and soil drought,oil content was still higher than under control,although ET weakened the beneficial effects of *** protein,ET offset the negative impacts of mild drought on protein content,but protein content was not increased under SRWC(45±5)%.Each stress or combined stress reduced oil and protein yields under all treatments,owing to declines in cottonseed *** combined stress reduced unsaturated fatty acid(UFA)/saturated fatty acid(SFA)and essential amino acid(EAA)/non-essential amino acid(NAA).Compared with PHY370 WR,the sensitivity of Sumian 15 to the combined factors was evidenced in the following ways:(1)seed yield,yield components,oil and protein yields were decreased more for Sumian 15 than PHY370 WR compared with the control treatment;(2)the combined stresses caused lower oil content,UFA,and UFA/SFA in Sumian 15 than PHY370 WR;(3)interaction effects of the combined factors on protein content and EAA/NAA were detected only in Sumian 15.

The need to simultaneously balance security and fairness in quantum key agreement(QKA) makes it challenging to design a flawless QKA protocol, especially a multiparty quantum key agreement(MQKA) protocol. When designing an MQKA protocol,two modes can be used to transmit the quantum information carriers: travelling mode and distributed mode. MQKA protocols usually have a higher qubit efficiency in travelling mode than in distributed mode. Thus, several travelling mode MQKA protocols have been proposed. However, almost all of these are vulnerable to collusion attacks from internal betrayers. This paper proposes an improved MQKA protocol that operates in travelling mode with Einstein-Podolsky-Rosen pairs. More importantly, we present a new travelling mode MQKA protocol that uses single photons, which is more feasible than previous methods under current technologies.

Continuous-variable quantum key distribution(CV-QKD) offers an approach to achieve a potential high secret key rate(SKR) in metropolitan areas. There are several challenges in developing a practical CV-QKD system from the laboratory to the real world. One of the most significant points is that it is really hard to adapt different practical optical fiber conditions for CV-QKD systems with unified hardware. Thus,how to improve the performance of practical CV-QKD systems in the field without modification of the hardware is very important. Here, a systematic optimization method, combining the modulation variance and error correction matrix optimization, is proposed to improve the performance of a practical CV-QKD system with a restricted capacity of postprocessing. The effect of restricted postprocessing capacity on the SKR is modeled as a nonlinear programming problem with modulation variance as an optimization parameter,and the selection of an optimal error correction matrix is studied under the same scheme. The results show that the SKR of a CV-QKD system can be improved by 24% and 200% compared with previous frequently used optimization methods theoretically with a transmission distance of 50 km. Furthermore, the experimental results verify the feasibility and robustness of the proposed method, where the achieved optimal SKR achieved practically deviates <1.6% from the theoretical optimal value. Our results pave the way to deploy high-performance CV-QKD in the real world.
