Abstract

Parthenogenesis and interspecific mating are alternative reproductive strategies that species have evolved alternative strategies when the opportunity of sexual reproduction is hindered by the natural environment. However, it is still unclear how to make a choice between parthenogenesis and interspecific mating when females are unable to reproduce sexually with males of the same species.This study mainly investigated the reproductive behaviour of female termites in the absence of male termites of the same species. Here, reproductive behaviours of females Reticulitermes aculabialis (Ra♀) were observed when they encountered a male R. flaviceps (Rf♂) with the absence of male R. aculabialis(Ra♂).The results showed that Ra♀‐Rf♂ tandems were more prevalent and stable compared to Ra♀‐Ra♀ tandems. When a tandem inadvertently broke apart, the female R. aculabialis displayed longer pauses while waiting for male R. flaviceps, but shorter pauses when another female R. aculabialis was involved. Furthermore, there were mating behaviour between female R. aculabialis and males R. flaviceps, resulting in offspring produced in paired Ra♀‐Rf♂ colonies were hybridization between female R. aculabialis and male R. flaviceps.These results suggest that interspecific mating and recombination is an important aspect for the choice of reproduction strategy, which will provide new insights into the trade‐off between gene contribution rate and genetic diversity.

Abstract

Sugar beet (Beta vulgaris) has emerged as one of the two primary crops, alongside sugarcane, for global sugar production. Comprehensively understanding sucrose synthesis, transport, and accumulation in sugar beet holds great significance for enhancing sugar production. In this study, we collected a diverse set of 269 sugar beet accessions worldwide and measured 12 phenotypes, comprising biomass, soluble sugar content, and 10 taproot-related traits. We re-sequenced 207 accessions to explore genetic diversity and population structure. Then we employed a genome-wide association study (GWAS) and RNA-seq to identify single-nucleotide polymorphisms and genes associated with natural phenotypic variations. Our findings revealed a panel of genes potentially regulating biomass and sugar accumulation, notably the dual-role geneUDP-glucose 4-epimerase, which genetically balances sugar accumulation and cell wall synthesis. In summary, this study provides a foundation for molecular breeding in sugar beet.

Abstract

In this paper, an alternative algorithm for simulating metamaterials under a narrow bandpass condition is proposed. To calculate metamaterial regions with unique double negative property, the Drude model is used to solve the constitutive relationship. The effectiveness of the proposed algorithm over existing methods is demonstrated in terms of accuracy, efficiency, and simulation of absorption. For the numerical example, a metamaterial slab with a dipole antenna model is introduced. Compared with previous works, the numerical results indicate that the proposed algorithm is considerably efficient and simulates absorption. Most importantly, the algorithm can maintain stability and reduce simulation duration. [ABSTRACT FROM AUTHOR]

Abstract

This paper provides an improved signal summing method for the spacecraft force limited vibration test system with eight force transducers. The key point for this method is to change the combination way of the signals coming out of the eight force transducers while the formulas inside the signal conditioning amplifier have been used skillfully. This method had been successfully adopted in the spacecraft force limited vibration test and the accuracy requirements of key force and moment signals have been met. And this method has been proved to be a very powerful tool for providing the critical force and moment data used to determine the force limited profile during the spacecraft dynamic test.

Abstract

During the orbit process of spacecraft, various disturbance sources inside would cause micro-vibration response, which reduces its observation resolution and affects the captured quality; so, it is necessary to conduct micro-vibration tests on the ground to evaluate spacecraft’ orbit performance. However, in the ground micro-vibration test, the noise generated by the internal disturbance of the spacecraft will produce a small response to structure due to the air effect that makes micro-vibration environment of high-resolution satellite on the ground is inconsistent with that in orbit. In order to research the influence of noise environment in the ground test, this paper analyzed CMG noise and its characteristics and used a small motor instead of CMG and designs satellite simulator on which micro-vibration test was designed based on transfer path analysis. Finally, the contribution of disturbance source was analyzed to evaluate the influence of CMG noise on micro-vibration test on the ground.

Abstract

There are different kinds of equipments distributed in different locations for a large complicated multi-shaker vibration test facility, so it is challenging to monitor the real state of test facility thoroughly during its operation. Long-term operation of this test facility will lead to the degradation of reliability and malfunction, and sometimes the emergency stop of the whole test system that threatens the safety of the spacecraft seriously. This paper presents in detail the design and application of a set of health monitoring device for a large multi-shaker vibration test facility which is capable of monitoring the operation state in real time and predicting the potential malfunction of the whole test facility to ensure the reliability of this large test system and safety of the spacecraft during its environmental vibration test.

Abstract

Peroxynitrite (ONOO-) is a highly reactive species that attacks a range of biological targets. The present study was designed to investigate the effect of ONOOon FaDu cells, a human hypopharyngeal cancer cell line, with special attention given to the PDCD4 gene expression in response to this oxidative stress. The in vitro cultured FaDu cells were subjected to various concentrations of ONOO-, then, the cell viability and morphological changes were examined by MTT assay and acridine orange staining, respectively. The protein expressions of Caspase-9, Caspase-3, and PDCD4 were determined by western blot and the mRNA expression of PDCD4 was analyzed by RT-PCR. This work demonstrated that ONOOcould inhibit the proliferation and induce apoptosis of FaDu cells. The protein expressions of Caspase-9, Caspase-3, and PDCD4 were up-regulated and, meanwhile, the mRNA expression of PDCD4 was increased, in response to ONOO-. These data suggest that ONOOcan effectively suppress proliferation of FaDu cells via triggering the apoptotic pathway. PDCD4 gene may play an important role in ONOO--induced apoptosis in FaDu cells, which may offer a new target for the treatment of hypopharyngeal carcinoma., Colegio de Farmacéuticos de la Provincia de Buenos Aires
