A chickpea simple sequence repeat (SSR) marker reference kit has been developed based on the genotyping of the global chickpea composite collection (3,000 accessions) with 35 SSR markers. The kit consists of three pools of chickpea accessions along with supporting documentation on the SSR markers, polymerase chain reaction and detection conditions, and the expected allele sizes for each of the 35 SSR loci. These markers were selected based on quality criteria, genome coverage and locus-specific information content. Other important SSR selection criteria were quality of amplification products, locus complexity, polymorphism information content and well-dispersed location on a chickpea genetic map. The developed SSR kit has a wide range of applications, especially for genetic diversity studies in chickpea. Using the markers and reference accessions in the kit, scientists in other laboratories will be able to compare the genotypic data that they obtain for their germplasm with that obtained using the global composite collection.

Introduction. The article focuses on monitoring the quality of education, analyzes the shortcomings of modern models and criteria functioning in this area. The purpose of the study is to build models and develop a criterion for their implementation in the field of education, free from these shortcomings. Materials and Methods. The methodology of solving this problem is based on the integration of mathematics and pedagogy (education studies) in the wide range of interactions of educational technologies, mathematical statistics and new results obtained by the author in the field of processing the findings of educational research investigations. Results. Achieving the goal includes three problems: the first is to build models for the study of dependent and independent samples; the second is to develop a single criterion for their implementation for the constructed models (instead of 12), free from known shortcomings; the third is to test and compare with other criteria in the process of solving specific problems in the field of education. The listed problems have been solved. Conclusions. The constructed models and the specified criterion are applicable for the study of dependent and independent samples, determine the direction of change caused by the introduction of a new educational technology, generalize almost all models and criteria known in this area.

Genome editing with CRISPR-Cas nucleases has been applied successfully to a wide range of cells and organisms. There is, however, considerable variation in the efficiency of cleavage and outcomes at different genomic targets, even within the same cell type. Some of this variability is likely due to the inherent quality of the interaction between the guide RNA and the target sequence, but some may also reflect the relative accessibility of the target. We investigated the influence of chromatin structure, particularly the presence or absence of nucleosomes, on cleavage by the Streptococcus pyogenes Cas9 protein. At multiple target sequences in two promoters in the yeast genome, we find that Cas9 cleavage is strongly inhibited when the DNA target is within a nucleosome. This inhibition is relieved when nucleosomes are depleted. Remarkably, the same is not true of zinc-finger nucleases (ZFNs), which cleave equally well at nucleosome-occupied and nucleosome-depleted sites. These results have implications for the choice of specific targets for genome editing, both in research and in clinical and other practical applications.

Abstract In the paper, the problem and importance of maintaining an appropriate level of quality in relation to labor protection in the light of EU and national legal standards have been presented. Maintenance of machines and, consequently, stability in the field of process quality is identified on the basis of specific management requirements according the machinery safety in food industry, also with respect to the sphere of their construction, production, distribution, and in particular exploitation. The food industry on global markets is characterized by a large variety of consumers. Therefore, both needs and requirements can have a very wide range, also with regard to quality criteria, care for the natural environment, development of technologies as well as new products introduction. Trends defining dynamics and competition in the food industry include a large number of factors, that require effective management, e.g.: quality ingredients of foodstuffs, preparation of products, maximum product safety as a measure of quality, application of modern production technologies (fast filling and packaging installations). Care for the safety of machinery and equipment used in industry and food processing is a guarantee of manufacturing products of the highest nutritional quality for consumers. With regard to ensuring the safety and quality of food products, in the paper the general principles in risk assessment and the technical measures to improve the safety of machines during their use have been presented.

AbstractThe shortest path problem (SPP) is a special network structured linear programming problem that appears in a wide range of applications. Classical SPPs consider only one objective in the networks while some or all of the multiple, conflicting and incommensurate objectives such as optimization of cost, profit, time, distance, risk, and quality of service may arise together in real-world applications. These types of SPPs are known as the multi-objective shortest path problem (MOSPP) and can be solved with the existing various approaches. This paper develops a Data Envelopment Analysis (DEA)-based approach to solve the MOSPP with fuzzy parameters (FMOSPP) to account for real situations where input–output data include uncertainty of triangular membership form. This approach to make a connection between the MOSPP and DEA is more flexible to deal with real practical applications. To this end, each arc in a FMOSPP is considered as a decision-making unit with multiple fuzzy inputs and outputs. Then two fuzzy efficiency scores are obtained corresponding to each arc. These fuzzy efficiency scores are combined to define a unique fuzzy relative efficiency. Hence, the FMOSPP is converted into a single objective Fuzzy Shortest Path Problem (FSPP) that can be solved using existing FSPP algorithms.

Centroid-based clustering is a widely used technique within unsupervised learning algorithms in many research fields. The success of any centroid-based clustering relies on the choice of the similarity measure under use. In recent years, most studies focused on including several divergence measures in the traditional hard k-means algorithm. In this article, we consider the problem of centroid-based clustering using the family of α β -divergences, which is governed by two parameters, α and β . We propose a new iterative algorithm, α β -k-means, giving closed-form solutions for the computation of the sided centroids. The algorithm can be fine-tuned by means of this pair of values, yielding a wide range of the most frequently used divergences. Moreover, it is guaranteed to converge to local minima for a wide range of values of the pair ( α , β ). Our theoretical contribution has been validated by several experiments performed with synthetic and real data and exploring the ( α , β ) plane. The numerical results obtained confirm the quality of the algorithm and its suitability to be used in several practical applications.
