Indexing k-mers in linear space for quality value compression.

Many bioinformatics tools heavily rely on [Formula: see text]-mer dictionaries to describe the composition of sequences and allow for faster reference-free algorithms or look-ups. Unfortunately, naive [Formula: see text]-mer dictionaries are very memory-inefficient, requiring very large amount of storage space to save each [Formula: see text]-mer. This problem is generally worsened by the necessity of an index for fast queries. In this work, we discuss how to build an indexed linear reference containing a set of input [Formula: see text]-mers and its application to the compression of quality scores in FASTQ files. Most of the entropies of sequencing data lie in the quality scores, and thus they are difficult to compress. Here, we present an application to improve the compressibility of quality values while preserving the information for SNP calling. We show how a dictionary of significant [Formula: see text]-mers, obtained from SNP databases and multiple genomes, can be indexed in linear space and used to improve the compression of quality value.

Anxiety and self-esteem as mediators of the relation between family communication and indecisiveness in adolescence

Abstract In this study, we explored the unique and common contributions of anxiety, self-esteem, and family communication on indecisiveness among adolescents. Three hundred and fifty pupils from 13 to 16 years of age completed selfreport measures on indecisiveness, quality of family communication, trait anxiety, and self-esteem. The findings in this study showed that students\u2019 indecisiveness is predicted by family communication mediated by anxiety and self-esteem. These results have important implications for practice as it stresses the importance of anxiety and self-esteem. Nevertheless, the counselors could also focus on enhancing relationship-building skills by introducing the adolescents\u2019 career formation as an adolescent\u2013parent joint project.L\u2019anxie\ub4te\ub4 et l\u2019estime de soi comme me\ub4diateurs de la relation entre communication au sein de la famille et indecision chronique a` l\u2019adolescence.

Ansiedad y Autoestima como Mediadores de la Relacio\ub4n entre Comunicacio\ub4n Familiar e Indecisio\ub4n en la Adolescencia. En este estudio, exploramos las contribuciones u\ub4nicas y comunes de la ansiedad, la autoestima y la comunicacio\ub4n de familia en la indecisio\ub4n de los adolescentes. Tres y cientos cincuenta alumnos entre los 13 y 16 an\u2dcos completaron auto-evaluaciones sobre la indecisio\ub4n, la calidad de comunicacio\ub4n familiar, los rasgos de ansiedad y la autoestima. Los resultados en este estudio muestran que la indecisio\ub4n en los estudiantes es prevista por la comunicacio\ub4n familiar mediada por la ansiedad y la autoestima. Estos resultados tiene importantes implicaciones para la practica ya que destacan la importancia de la ansiedad y la autoestima. Sin embargo, los consejeros podr\u131\ub4an tambie\ub4n focalizarse en el aumento de sus habilidades para construir relaciones mediante la introduccio\ub4n de la formacio\ub4n profesional para adolescentes como un proyecto conjunto del adolescente-padre.Angst und Selbstwertgefu\ua8 hl als Mediatoren der Beziehung zwischen Kommunikation in der Familie und Unentschlossenheit in der Adoleszenz. In dieser Studie untersuchten wir die spezifischen und gemeinsamen Beitra\ua8ge von Angst, Selbstwertgefu\ua8hl und Kommunikation in der Familie auf Unentschlossenheit unter Jugendlichen. Dreihundertfu\ua8nfzig Schu\ua8ler, zwischen 13 bis 16 Jahre alt, fu\ua8llten Skalen zur Unentschlossenheit, Qualita\ua8t der Kommunikation in der Familie, A\ua8 ngstlichkeit und Selbstwertgefu\ua8hl aus. Die Ergebnisse dieser Studie zeigten, dass Unentschlossenheit der Schu\ua8ler von Kommunikation in der Familie vorhergesagt wird, vermittelt durch Angst und Selbstwertgefu\ua8 hl. Diese Ergebnisse haben wichtige Implikationen fu\ua8r die Praxis, da sie die Bedeutung von Angst und Selbstwertgefu\ua8hl hervorheben. Dennoch ko\ua8nnten sich die Beratungspersonen durch die Einfu\ua8hrung der beruflichen Bildung der Jugendlichen als ein gemeinsames Projekt von Jugendliche-Elternteil auch auf die Verbesserung der Fa\ua8higkeiten zum Aufbau von Beziehungen konzentrieren

Variable-order reference-free variant discovery with the Burrows-Wheeler Transform

Background: In [Prezza et al., AMB 2019], a new reference-free and alignment-free framework for the detection of SNPs was suggested and tested. The framework, based on the Burrows-Wheeler Transform (BWT), significantly improves sensitivity and precision of previous de Bruijn graphs based tools by overcoming several of their limitations, namely: (i) the need to establish a fixed value, usually small, for the order k, (ii) the loss of important information such as k-mer coverage and adjacency of k-mers within the same read, and (iii) bad performance in repeated regions longer than k bases. The preliminary tool, however, was able to identify only SNPs and it was too slow and memory consuming due to the use of additional heavy data structures (namely, the Suffix and LCP arrays), besides the BWT. Results: In this paper, we introduce a new algorithm and the corresponding tool ebwt2InDel that (i) extend the framework of [Prezza et al., AMB 2019] to detect also INDELs, and (ii) implements recent algorithmic findings that allow to perform the whole analysis using just the BWT, thus reducing the working space by one order of magnitude and allowing the analysis of full genomes. Finally, we describe a simple strategy for effectively parallelizing our tool for SNP detection only. On a 24-cores machine, the parallel version of our tool is one order of magnitude faster than the sequential one. The tool ebwt2InDel is available at github.com/nicolaprezza/ebwt2InDel. Conclusions: Results on a synthetic dataset covered at 30x (Human chromosome 1) show that our tool is indeed able to find up to 83% of the SNPs and 72% of the existing INDELs. These percentages considerably improve the 71% of SNPs and 51% of INDELs found by the state-of-the art tool based on de Bruijn graphs. We furthermore report results on larger (real) Human whole-genome sequencing experiments. Also in these cases, our tool exhibits a much higher sensitivity than the state-of-the art tool
