Tassel traits are important in maize breeding programs aiming to reduce the size and number of branches and maintain satisfactory pollen production in order to increase grain yield. The objectives of this study were to determine the sample size (number of tassels) required to estimate the mean values for tassel traits in maize genotypes and to verify the variability of sample size among genotyp...

Twenty available genotypes of maize were screened for resistance to Chilo partellus in the field. The genotype Sahiwal 2002 was found to be most susceptible while DK-6525 was most resistant. Maximum infestation was observed at the end of April while the minimum in the last week of March. Significant variations were observed in all the plant characters viz., number of nodes per plant, plant heig...

Abstract Cyanobacteria like Arthrospira platensis and Nostoc muscorum are known to be beneficial for plant development. They can improve growth, yield, proximate content (protein carbohydrate), stimulate tolerance abiotic stresses herbicides. In the present study, impacts of brominal herbicide (Bh) alone or in combination with natural cyanobacterial synthetic tryptophan treatments were investig...

Distinguishing excitatory from inhibitory neurons with multielectrode array (MEA) recordings is a serious experimental challenge. The current methods, developed in vitro, mostly rely on spike waveform analysis. These however often display poor resolution and may produce errors caused by the variability of spike amplitudes and neuron shapes. Recent recordings in human brain suggest that the spik...

High-throughput sequencing of 16S rRNA gene amplicons (16S-seq) has become a widely deployed method for profiling complex microbial communities but technical pitfalls related to data reliability and quantification remain to be fully addressed. In this work, we have developed and implemented a set of synthetic 16S rRNA genes to serve as universal spike-in standards for 16S-seq experiments. The s...

Abstract Tools to monitor SARS-CoV-2 transmission and immune responses are needed. We present a neutralization ELISA determine the levels of Ab-mediated virus preclinical model focused immunization strategy. The is strongly correlated with elaborate plaque reduction test (? = 0.9231, p < 0.0001). potency convalescent sera correlates IgG titers against receptor-binding domain (RBD) spike ...

In many species, neurons with highly selective stimulus-response properties characterize higher order sensory areas and/or sensory motor areas of the CNS. In the songbird nuclei, the responses of HVC (used as a proper name) neurons during playback of the bird's own song (BOS) are probably one of the most striking examples of selectivity for natural stimuli. We examined here to what extent spike...

Soil salinization requires developing genetically salt-tolerant and high-yielding genotypes, especially in semi-arid arid regions. In this study, two new Tunisian durum wheat cultivars, INRAT100 Dhahbi, were tested for the first time a semi-closed environment against salinity (0, 6 12 dS m-1). Dry weight of aerial root parts, plant height, number tillers per plant, spike awn length, grain yield...

Various statistical methods were applied in this research: analysis of genetic parameters, Pearson's correlation, genotypic and phenotypic correlations, Path analysis, with the aim creating a selection criterion for increasing wheat grain yield. A two-year experimental study was conducted twenty-seven genotypes, grown on two localities: Rimski Šančevi (Bačka, Vojvodina), Chernozem soil type; Ku...

The Spike-Timing-Dependent Plasticity (STDP) learning strengthens or weakens synaptic weights of a neural network according to differences of synaptic spike timings. By the STDP rule, the neural network temporally evolves by learning an input spatiotemporal pattern. In the learning process, estimating a characteristic path length and a clustering coefficient, we examined how a structure of the ...
