Prolonged storage of rice seeds can lead to a decrease in seed vigor and seedling quality. The Lipoxygenase (LOX) gene family is widely distributed plants, LOX activity closely related viability stress tolerance. In this study, the lipoxygenase OsLOX10 from 9-lipoxygenase metabolic pathway was cloned rice, its roles determining longevity tolerance saline-alkaline caused by Na2CO3 seedlings were mainly investigated. CRISPR/Cas9 knockout increased compared with wild-type overexpression lines...
The pandemic of respiratory diseases enlightened people that monitoring respiration has promising prospects in averting many fatalities by tracking the development diseases. However, response speed current optical fiber sensors is still insufficient to meet requirements high-frequency detection during failure. Here, a scheme for fast and stable tachypnea monitor proposed utilizing water-soluble C60-Lys ion compound as functional material humidity change progression breath. polarization can...

With the robust growth of national economy, demand for oil and natural gas continues to rise, heightening significance pipeline transportation in energy sector. However, long-term operations are often subjected factors such as corrosion, aging, damage, which can result leaks safety incidents, posing significant threats life, property, environmental integrity. Consequently, timely precise detection defects estimation their sizes hold paramount practical importance. This research endeavors...
Abstract Based on the geometric properties of a simplex, endmembers can be extracted automatically from hyperspectral image. To avoid shortcomings N-FINDR algorithm, which requires dimensions data to one less than number needed, new volume formula for simplex without requirement dimension reduction is presented here. We demonstrate that algorithm special case method. Moreover, whether null vector included as an endmember has important effect final result extraction. Finally, we compare...
Abstract Background Phosphoenolpyruvate carboxylase (PEPC) plays an important role in the primary metabolism of higher plants. Several studies have revealed critical importance PEPC interaction carbon and nitrogen metabolism. However, function mechanism is unclear needs further investigation. Results This study indicates that transgenic rice expressing sugarcane C4-PEPC gene displayed shorter roots fewer crown at seedling stage. total content was significantly than wild type (WT) Proteomic...
This letter proposes a small target detection method for the hyperspectral image based on higher order statistics. first calculates coskewness tensor of image, followed by orthogonal decomposition using singular value decomposition. The obtained vectors are then used to perform transform centralized image. Compared popular blind source separation techniques, presented keeps clear nonconvergence. Experiments with real show that interested will be in few bands (even band) very clearly after...
The joint diagonalization technique is an important type of method for blind source separation. In this paper, a new approach presented to set symmetric matrices with general (and not necessarily orthogonal) matrix. performs via series eigen decompositions, including merits simplicity, effectiveness, and computational efficiency. Simulation results demonstrate the potential improvement performance in context
This letter presents a new endmember generation method, which is called the geometric optimization model (GOM). The algorithm exploits following fact: an <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">L</i> -dimensional ( -D) simplex can be divided into + 1 -D smaller simplexes by any point within simplex, and sum of volumes equal to volume simplex. Based on this geometrical property, we propose objective function for generation, whose variable...
The constrained energy minimization (CEM) and matched filter (MF) are two most frequently used target detection algorithms in the remotely sensed community. In this paper, we first introduce an augmented CEM (ACEM) by adding a N-dimensional band consisting of 1's. According to recently published conclusion that can always achieve better performance any linearly independent bands, ACEM is than CEM. Further, prove mathematically equivalent MF. As result, conclude classical superior operator.
Stress is one of the main issues in agricultural production. Drought stress has a significant impact on plant growth and development, reduces crop yield, can result environmental degradation. Plants have evolved series adaptations to natural at morphological, physiological, biochemical, cellular, molecular levels, such as escape, tolerance, resistance. Therefore, it very important understand effects drought plants, sensing, transduction, response signals, for improving yields. ROS, an...
Rice ratooning has traditionally been an important component of the rice cropping system in China. However, compared with first harvest, few studies on factors effecting ratoon yield have conducted. Because is a one-season cultivated using axillary buds that germinate stakes and generate panicles after crop's its production mainly affected by growth buds. The objectives this study were to evaluate sprouting mechanism improve yield.First, we observed differentiation dynamics at different...
Disentanglement learning aims to separate explanatory factors of variation so that different attributes the data can be well characterized and isolated, which promotes efficient inference for downstream tasks. Mainstream disentanglement approaches based on generative adversarial networks (GANs) learn interpretable representation. However, most typical GAN-based works lack discussion latent subspace, causing insufficient consideration independent factors. Although some recent research...
In this letter, we present a new nonorthogonal algorithm for joint diagonalization of set symmetric matrices. The alternates between updates individual demixing matrix rows, and the update each row is transferred to solving eigenvector problem. By using some blind source separation simulations, show that obviously obtains an improved performance when signal-to-noise ratio observed signals relatively low.
Simplex volume is the most commonly used parameter for endmember extraction. However, when outliers exist in image, maximum-volume-criterion (MVC)-based methods tend to extract them as endmembers. Those outlier endmembers could be either physically meaningless or not representative enough prevalent land covers. This biggest bottleneck preventing MVC-based from being extended theoretical analysis practical applications. mainly due limitation of simplex formula itself, which only determined by...
