Deletion of beta-fructofuranosidase (invertase) genes is associated with sucrose content in Date Palm fruit

2019

AbstractThe fruit of date palm trees are an important part of the diet for a large portion of the Middle East and North Africa. The fruit is consumed both fresh and dry and can be stored dry for extended periods of time. Date fruits vary significantly across hundreds of cultivars identified in the main regions of cultivation. Most dried date fruit are low in sucrose but high in glucose and fructose. However, high sucrose content is a distinctive feature of some date fruit and affects flavor as well as texture and water retention. To identify the genes controlling high sucrose content we analyzed date fruit metabolomics for association with genotype data from 121 date fruits. We found signif…

Analogy Construction and Success in Mathematics and Science Problem-solving: a Study with Secondary Students // Construcción de analogías y éxito en …

2012

We conducted an empirical study to analyse the association between students’ perception of surface and structural analogies between problems, and their algebraic success. Different surface and structural relationships between one ‘source’ problem and ‘target’ problems were considered. We also considered high (daily life) and low (scientific) familiarity contexts. Algebraic success was measured by the equations selected to solve each problem. Similarities and differences between problems were explicitly asked to students. Results showed a significant correlation between detecting the correct structural relation between problems and selecting the correct equations to solve them. Low familiari…

Robotics and automation for societal good : global South challenges and technology-policy considerations

2018

Robotics and automation and artificial intelligence technologies hold immense potential in addressing many of the societal challenges as exemplified in the sustainable development goals of the 2030 agenda of the United Nations. They have the potential not only to increase the standard of living in developed countries, but to improve the quality of life in the so-called «Global South». This article discusses underlying challenges and technology-policy considerations when deploying emerging technologies in developing and developed economies. Various examples and implementations in collaboration with humanitarians, researchers and developers, and professional organizations across the globe are…

The problems and promises of research into human immunology and autoimmune disease

2012

Translational research in autoimmunity is hampered by a number of hurdles, including a lack of knowledge regarding initiating and pathologically relevant autoantigens, the low frequency of autoreactive pathogenic B and T cells, difficulty in accessing the affected tissue, differences between self-reactive and pathogen-specific lymphocytes, a lack of etiologically relevant preclinical animal models and the heterogeneity of disease presentation. Given the need for biomarkers and new therapeutics, it is imperative that these hurdles be surmounted.

Związek metropolitalny jako forma związku publicznoprawnego

2021

Od wielu lat poszukuje się formy prawnej właściwej dla zarządzania obszarami silnie zurbanizowanymi, obejmującymi wielomiejskie tereny o skomplikowanych układach społecznych, gospodarczych, komunikacyjnych oraz administracyjnych. Związek metropolitalny w województwie śląskim funkcjonuje czwarty rok. Także inne duże miasta wraz z gminami sąsiadującymi oczekują objęcia zbliżoną formą organizacji w celu realizacji zadań publicznych. Wśród wielu pytań pojawia się takie: czym jest związek metropolitalny w sensie prawnym? Niniejszy artykuł jest próbą sprawdzenia, na ile koncepcja Tadeusza Bigi z 1928 roku jest aktualna i czy może służyć jako pewien model teoretycznoprawny. Cechami związku publicz…

Genome-wide analyses reveal population structure and identify candidate genes associated with tail fatness in local sheep from a semi-arid area.

2021

Abstract Under a climate change perspective, the genetic make-up of local livestock breeds showing adaptive traits should be explored and preserved as a priority. We used genotype data from the ovine 50 k Illumina BeadChip for assessing breed autozygosity based on runs of homozygosity (ROH) and fine-scale genetic structure and for detecting genomic regions under selection in 63 Tunisian sheep samples. The average genomic inbreeding coefficients based on ROH were estimated at 0.017, 0.021, and 0.024 for Barbarine (BAR, n = 26), Noire de Thibar (NDT, n = 23), and Queue fine de l'Ouest (QFO, n = 14) breeds, respectively. The genomic relationships among individuals based on identity by state (I…

A probabilistic condensed representation of data for stream mining

2014

Data mining and machine learning algorithms usually operate directly on the data. However, if the data is not available at once or consists of billions of instances, these algorithms easily become infeasible with respect to memory and run-time concerns. As a solution to this problem, we propose a framework, called MiDEO (Mining Density Estimates inferred Online), in which algorithms are designed to operate on a condensed representation of the data. In particular, we propose to use density estimates, which are able to represent billions of instances in a compact form and can be updated when new instances arrive. As an example for an algorithm that operates on density estimates, we consider t…

Teacher Perceptions of Reading Motivation in Children with Developmental Dyslexia and Average Readers

2017

Abstract Purpose. This study assessed the teacher perceptions of reading engagement and several components of reading motivation in children with developmental dyslexia and average readers, in an attempt to more clearly understand the role of motivation in developmental dyslexia Method. Sixty-eight children participated in this study. Thirty-three children made up the group with developmental dyslexia and thirty-five made up the group of average readers. In order to assess the reading motivation of the participants, teachers filled two instruments: (a) The Reading Engagement Index ( Wigfield et al., 2008 ), a teacher rating of the engaged reader, and (b) Teacher questionnaire on student mot…

Multiple independent variants at the TERT locus are associated with telomere length and risks of breast and ovarian cancer

2013

Journal article TERT-locus SNPs and leukocyte telomere measures are reportedly associated with risks of multiple cancers. Using the Illumina custom genotyping array iCOGs, we analyzed ~480 SNPs at the TERT locus in breast (n = 103,991), ovarian (n = 39,774) and BRCA1 mutation carrier (n = 11,705) cancer cases and controls. Leukocyte telomere measurements were also available for 53,724 participants. Most associations cluster into three independent peaks. The minor allele at the peak 1 SNP rs2736108 associates with longer telomeres (P = 5.8 × 10!-7), lower risks for estrogen receptor (ER)-negative (P = 1.0 × 10!-8) and BRCA1 mutation carrier (P = 1.1 × 10!-5) breast cancers and altered promot…

Learning to associate written letters with speech sounds is crucial for the initial phase of acquiring reading skills. However, little is known about the cortical reorganization for supporting letter-speech sound learning, particularly the brain dynamics during the learning of grapheme-phoneme associations. In the present study, we trained 30 Finnish participants (mean age: 24.33 years, SD: 3.50 years) to associate novel foreign letters with familiar Finnish speech sounds on two consecutive days (first day ​~ ​50 ​min; second day ​~ ​25 ​min), while neural activity was measured using magnetoencephalography (MEG). Two sets of audiovisual stimuli were used for the training in which the graphe…
