Coding Sequences with Constraints
1990
In this paper we consider the following problem: given all bi-infinite sequences of symbols satisfying certain constraints, search for a set X of words such that i): any concatenation of elements of X satisfies these constraints and ii): any sequence verifying the constraints can be “parsed” in elements of X.
A Generalization of Girod's Bidirectional Decoding Method to Codes with a Finite Deciphering Delay
2012
Girod’s encoding method has been introduced in order to efficiently decode from both directions messages encoded by using finite prefix codes. In the present paper, we generalize this method to finite codes with a finite deciphering delay. In particular, we show that our decoding algorithm can be realized by a deterministic finite transducer. We also investigate some properties of the underlying unlabeled graph.
Effects of a French remedial program on pupils’ educational outcomes
2018
International audience; Few studies have examined the French “Networks for Specialized Assistance to Pupils in Difficulty” (Rased). In this article, we evaluate the impact of receiving Rased services in the first year of primary schooling on academic success. Using data from a national panel study, we find inconsistency in student selection within Rased. Using matching methods, our results reveal that pupils who benefited from the program school have a higher probability of grade repetition and obtain significantly lower scores on the third grade national assessment, particularly in mathematics, compared to pupils with similar characteristics who did not take part in the program. This impac…
Centrality in primate-parasite networks reveals the potential for the transmission of emerging infectious diseases to humans
2013
We thank Randi Griffin, Amy Pedersen, Rosa Menendez, Mark Lineham, and two anonymous reviewers for discussion and comments on a previous draft. This work was funded by the Spanish Ministry of Science (J.M.G. and M.V.), by the Junta de Andalucia (J.M.G.), and by National Science Foundation Grants DEB-0211908 and EF-0723939/0904359 (C.L.N.).
A probabilistic rainfall model to estimate the leading-edge lifetime of wind turbine blade coating system
2021
Rain-induced leading-edge erosion of wind turbine blades is associated with high repair and maintenance costs. For efficient operation and maintenance, erosion models are required that provide estimates of blade coating lifetime at a real scale. In this study, a statistical rainfall model is established that describes probabilistic distributions of rain parameters that are critical for site-specific leading-edge erosion assessment. A new droplet size distribution (DSD) is determined based on two years’ onshore rainfall data of an inland site in the Netherlands and the obtained DSD is compared with those from the literature. Joint probability distribution functions of rain intensities and dr…
Rapid screening of the LDL receptor point mutation FH-Genoa/Palermo
1999
The LDL-receptor gene point mutation FH-Genoa/Palermo is the most frequent mutation responsible for Familial Hypercholesterolemia in Sicily. The mutation does not introduce or abolish any useful restriction site. We establish a GeneComb™-based strategy to identify this mutation in a population of Sicilian unrelated clinically diagnosed FH probands. The method was very sensitive and specific; 12 out of 90 (13.3%) unrelated FH probands were found to carry the FH-Genoa/Palermo mutation. According to these results, the FH-Genoa/Palermo is the more frequent LDL-receptor gene mutation among the Sicilian FH patients. Moreover FH-Genoa/Palermo is the mutation cluster to date more represented in Sou…
Inheritance and variable expression in Rubinstein-Taybi syndrome.
2010
Familial Rubinstein-Taybi syndrome (RTS) is very rare. Here we report on the 6th and 7th case of inherited RTS. Family 1 presents with incomplete or mild RTS over three generations; a 13-year-old girl (proband 1) with mild but typical facial features and learning disabilities, her very mildly affected mother (proband 2), and the maternal grandmother (proband 3). Family 2 includes three females with classical RTS (probands 4-6) and their father (proband 7) with broad thumbs and halluces. Proband 5 also had a brain tumor (ganglioglioma) at the age of 3 years. In probands 1-3, direct sequencing identified a novel CREBBP missense mutation, c.2728A > G (predicting p.Thr910Ala), that was absent i…
Lack of phenotypic additive effect of familial defective apolipoprotein B3531 in familial hypercholesterolaemia.
2020
Familial defective apolipoprotein (apo) B (FDB) and familial hypercholesterolaemia (FH) are the two common genetic conditions that cause hypercholesterolaemia. R3531C mutation of the APOB gene is a rare cause of FDB. Individuals with both FDB and FH are rare. A 51-year-old man with hypercholesterolaemia (11.4 mmol/L) and his family were studied. Low-density lipoprotein (LDL) receptor (LDLR) and APOB genes were analysed by direct sequencing. LDL of four subjects were studied in a fibroblast LDL receptor-binding displacement assay. We found a mutation of the LDLR gene (p.Y398X) in the proband and in four other family members: the p.R3531C APOB gene mutation was also found in the proband, his …
Genotype–phenotype correlation in a new Fabry-disease-causing mutation
2019
Background: Fabry disease (FD) is a rare X-linked inherited lysosomal storage disorder caused by α-galactosidase A deficiency leading to intracellular glycosphingolipid accumulation. FD manifestation is multisystem, and can differ depending on disease-related genetic variants. Currently, more than 700 different FD-causing mutations have been identified in the human GLA gene. We identified a novel mutation in a Lithuanian family with classical manifestations of Fabry disease, revealing severe effects to the cardiovascular systems of heterozygous women. Case presentation: A 49-year-old woman underwent echocardiography due to progressive dyspnea that lasted seven years, reduced physical a…
Convolutional Neural Network-Based Human Movement Recognition Algorithm in Sports Analysis
2021
In order to analyse the sports psychology of athletes and to identify the psychology of athletes in their movements, a human action recognition (HAR) algorithm has been designed in this study. First, a HAR model is established based on the convolutional neural network (CNN) to classify the current action state by analysing the action information of a task in the collected videos. Secondly, the psychology of basketball players displaying fake actions during the offensive and defensive process is investigated by combining with related sports psychological theories. Then, the psychology of athletes is also analysed through the collected videos, so as to predict the next response action of the …
