Natural Variation of Leaf Thickness and Its Association to Yield Traits in indica Rice

Journal of Integrative Agriculture 2014年第2期13卷 316-325页

Leaf thickness is an important morphological trait in rice. Its association to the yield potential, as of now has not been documented because of the shortage of the equipment which could conveniently measure the leaf thickness in rice. In this study, the thickness of top three leaves of 208 cultivars had been determined by a nondestructive rice leaf thickness instrument for the research of the natural variation of leaves thickness and its association to yield traits in indica rice. The results showed that the flag leaf was the thickest, and the 2nd leaf was thicker than the 3rd leaf. Analysis of variance indicated the existence of wide genetic diversity of leaf thickness among the investigated indica rice genotypes. The tight correlation among the thicknesses of the top three leaves means that the leaf thickness traits share one genetic control system. Leaf thickness had a significant positive correlation with leaf length and a positive correlation with leaf width, indicated that thicker leaf was beneficial to increasing the single leaf area. The results of correlation analysis revealed that thicker leaf should be profitable to the leaf erection, higher numbers of grains per panicle and higher grains weight per panicle. However, the significantly negative correlation between leaf thickness and number of panicles per plant counteracted the profitability from increased grains weight per panicle, so that the correlations of the thicknesses of the top three leaves to yield and biomass were positive but not significantly. It has made great progress in the genetic improvement of leaves thickness in inbred indica rice breeding in Guangdong Province, China, since the 1990s.

BACKGROUND: It has been demonstrated that the C-106T polymorphism at promotor region of aldose reductase gene and GLU298ASP (894G-T) polymorphism at exon 7 of endothelial nitric oxide synthase (eNOS) gene are associated with diabetic nephropathy, it should be further studied whether the risk for diabetic nephropathy will increase when the above polymorphic sites coexist。OBJECTIVE: To investigate the association between the coexistence of the polymorphisms of both the C-106T at promotor region of aldose reductase gene and GLU298ASP (894G-T) at exon 7 of eNOS gene in chromosome 7q35 region and the genesis of diabetic nephropathy in northern Chinese Han people。DESIGN : A case-controlled, comparative observation SETTING : Department of Endocrinology, the Affiliated Hospital of Medical College, Qingdao University PARTICIPANTS: Totally 139 inpatients with type 2 diabetes mellitus were selected from the Department of Endocrinology, the Affiliated Hospital of Medical College, Qingdao University from November 2002 to April 2005, including 54 males and 85 females, (64±8) years of age。Inclusive criteria: Accorded with the standards of diabetic diagnosis and classification by WHO in 1999。According to the 24-hour urinary albumin excretion rate (UAER), they were divided into diabetic nephropathy group (n =61 ) and non-diabetic nephropathy group (n =78)。Meanwhile, 63 healthy controls were selected as the control group, including 24 males and 39 females, 50-78 years of age。All the enrolled subjects were Han people。Informed contents were obtained from all the subjects。METHODS: The genotypes and alleles of polymorphisms of GLU298ASP(894G-T) at exon 7 of eNOS gene and C-106T at promotor region of aldose reductase gene were detected by polymerase chain reaction restriction-fragment length polymorphism technique (PCR-RFLP), DNA sequencing technique and agarose gel electrophoresis separation technique。Then the frequency of genotypes and alleles were compared。MAIN OUTCOME MEASURES :①Polym

Unraveling post-growth mechanisms of monolayer CsPbBr3 nanocubes:Laser-enhanced transformations and cathodoluminescence-electron microscopy correlations

Journal of Energy Chemistry 2025年第1期100卷 146-156页

Lead-halide perovskite nanoparticles（LHP NPs） are highly promising materials for next-generation displays and solid-state lighting due to their exceptional optical properties. However, their inherent instability presents a significant challenge. Recent advances have demonstrated that optoelectronic devices based on monolayer nanoparticle films exhibit both high luminescence efficiency and long-term *** research demonstrates that mobility limitations and anisotropic alignments in CsPbBr3nanocube monolayer films are key to their stabilization, hindering spontaneous growth through face-to-face fusion and resulting in the formation of connecting necks in a diagonal direction. Introducing laser irradiation confirmed this by significantly accelerating nanocubes growth, increasing mobility, and enhancing local structural ordering, leading to larger and more regularly shaped nanosheets. Fourier transform infrared spectroscopy and energy dispersive spectroscopy line-scan analyses indicated that laser irradiation did not disrupt the ligand structure. Transmission electron microscopy and correlative cathodoluminescence electron microscopy revealed the effects of post-growth and heterogeneous structures, including enhanced luminescence and inhomogeneous intensity in the nanosheets. These findings deepen the understanding of the post-growth mechanism of monolayer nanoparticles and the structure-emission correlation and highlight the unique role of laser irradiation in directing the formation of well-defined and regular nanostructures.

Leader-follower: Human-centered intention-guided controller for novel Superlimb with application to load-carrying scenarios

Science China Technological Sciences 2025年第1期 325-338页

Supernumerary robotic arms(Superlimb) are a new type of wearable robot that works closely with humans as a third hand to augment human operation capability. Accurate conveyance of wearers' intentions, allocation of roles, and humancentered interaction considerations are the key points in the process of human–Superlimb collaboration. This paper proposes a human-centered intention-guided leader–follower controller that relies on the dynamic modeling of Superlimb with application to load-carrying scenarios. The proposed leader–follower controller takes the human as the leader and the Superlimb as the follower, achieving effective information communication, autonomous coordination, and good force compliance between Superlimb, humans, and the environment under human safety assurance. First, the human–Superlimb dynamic system is modeled to achieve force interaction with the environment and wearer. Second, to achieve the precise intention extraction of humans, pose data from five visual odometry sensors are fused to capture the human state, the generalized position, the velocity of hands, and the surface electromyography signals from two myoelectric bracelets sensors are processed to recognize the natural hand gestures during load-carrying scenarios by a designed Swin transformer network. Then, based on the real-time distance detection between human and mechanical limbs, the security assurance and force-compliant interaction of the human–Superlimb system are realized. Finally, the human hand muscle intention recognition, human–robot safety strategy verification,and comparative load-carrying experiments with and without the proposed method are conducted on the Superlimb *** showed that the task parameters are well estimated to produce more reasonable planning trajectories, and Superlimb could well understand the wearer's intentions to switch different Superlimb actions. The proposed sensor-based human–robot communication framework motivates future studies of o
