Aim. Drought is one of the most harmful abiotic stresses limiting crop productivity. We study ability photosynthetic apparatus winter wheat varieties differing in their tolerance to acclimate moderate drought stress under pot experiment. Methods. Dynamics relative water content (RWC), chlorophyll content, CO2 assimilation rate (Pn), activity antioxidant enzymes chloroplasts flag leaf drought-to...

While graph neural networks (GNNs) have achieved notable success in various mining tasks, conventional GNNs only model the pairwise correlation 1-hop neighbors without considering long-term relations and high-order patterns, thus limiting their performances. Recently, several works addressed these issues by exploring motif, i.e., frequent subgraphs. However, methods usually require an unaccepta...

This experiment aimed to determine the adaptability of four biodiesel-producing plants gold mine wastewater based on morpho-physiological properties. Four species namely jatropha (Jatropha curcas), castor bean (Ricinus communis), wild candlenut (Reutealis trisperma) and bead tree (Melia azedarach) were grown in water culture using Hoagland solution for 2 weeks then treated with mining at 0% (co...

Objectives—Genitourinary tract samples are required to investigate male HIV-1 infectivity. Because semen collection is often impractical, we evaluated the acceptability, feasibility, and validity of post-prostatic massage fluid/urine (post-PMF/U) for studying male genitourinary HIV-1 shedding. Methods—HIV-1-seropositive men were evaluated after 48 hours of sexual abstinence. At each visit, a cl...

Osmotic and turgor adjustment in roots, shoots, and whole sporophytes of a NaCI-tolerant mutant and a NaCI-sensitive wildtype strain of the fern Ceratopteris richardii Brongn. were charactenzed following exposure to 60 millimolar NaCI, using a psychrometric approach to pressure-volume analysis. Water potential components of whole plants and shoots at full or ambient hydration were similar betwe...

in order to investigate the effects of drought stress and nitrogen fertilizer on photosynthesis rate and some physiological characteristics in two barley cultivars, a pot experiment was conducted using a randomized complete block design as a factorial experiment with three factors including water stress, nitrogen fertilizer and barley cultivars in three replications. irrigation treatments condu...

in order to have a successful breeding program, it is important to determine the relationship among the traits. this study was conducted at research farm of isfahan university of technology to evaluate relationships among some of the agronomic and physiological traits and grain yield of ten bread wheat cultivars in optimum and stress moisture (irrigation after 70±3 and 130±3 mm evaporation from...

In this paper we describe a method of audio chord estimation than does not rely on any machine learning technique. We calculate a beat-synchronized spectrogram with high time and frequency resolution. The sequence of chroma vectors (CRP features based on constant-Q transform) obtained from spectrogram is smoothed using self-similarity matrix before the actual chord recognition. Binary chord tem...

An in-orbit experiment was launched to evaluate the performance of the spaceborne high precision fiber optic gyroscopes (FOG). The three-axis in-orbit data of the FOG were analyzed using wavelet analysis method. Features of low frequency period terms and glitch noise were demonstrated. In addition, a method to extract the random noise from the in-orbit data is proposed based on the first-order ...
