Wardowski conditions to the coincidence problem
2015
In this article we first discuss the existence and uniqueness of a solution for the coincidence problem: Find p ∈ X such that Tp = Sp, where X is a nonempty set, Y is a complete metric space, and T, S:X → Y are two mappings satisfying a Wardowski type condition of contractivity. Later on, we will state the convergence of the Picard-Juncgk iteration process to the above coincidence problem as well as a rate of convergence for this iteration scheme. Finally, we shall apply our results to study the existence and uniqueness of a solution as well as the convergence of the Picard-Juncgk iteration process toward the solution of a second order differential equation.

On decoupling in Banach spaces
2021
AbstractWe consider decoupling inequalities for random variables taking values in a Banach space X. We restrict the class of distributions that appear as conditional distributions while decoupling and show that each adapted process can be approximated by a Haar-type expansion in which only the pre-specified conditional distributions appear. Moreover, we show that in our framework a progressive enlargement of the underlying filtration does not affect the decoupling properties (in particular, it does not affect the constants involved). As a special case, we deal with one-sided moment inequalities for decoupled dyadic (i.e., Paley–Walsh) martingales and show that Burkholder–Davis–Gundy-type in…
Stabilization of ZSM-5 zeolite catalysts for steam catalytic cracking of naphtha for production of propene and ethene
2012
In order to increase ethene and propene, naphtha steam catalytic cracking has been considered. The cracking of C 5-C 12 n-alkanes with ZSM-5 has been studied in absence and in presence of steam and the influence of the operation variables was studied. Irreversible catalyst deactivation by dealumination also occurs in the reactor when the cracking is carried out in the presence of steam. To diminish steam deactivation, the influence of zeolite Si/Al framework and a postsynthesis treatment by phosphorous have been studied and optimized. Much more stable catalyst can be achieved that result in an increase in activity without penalty for production of ethene and propene.
Improvisation for innovation: The contingent role of resource and structural factors in explaining innovation capability
2018
The file attached to this record is the author's final peer reviewed version. The Publisher's final version can be found by following the DOI link. This paper focuses on resource and structural factors to explore the relationship between organizational improvisation and innovation capability. Although the role of improvisation has attracted increasing academic attention in fast-changing environments, little is known about the conditions under which firms benefit from improvisation. This paper addresses this gap using an organizational learning perspective that explains the role of a firm's organizational structure and organizational resources for improvisation and innovation. A large-scale …
La performance académique des étudiants en première année universitaire : influence des capacités cognitives et de la motivation
2012
Today, academic failure is closely monitored, especially when first year students are concerned. The aim of this dissertation is the comprehension of the mechanism that builds academic success. The approach is both quantitative and integrative. For this purpose, data have been collected from 700 first year students in social administration, law and psychology areas in the university of Burgundy. Collected information allows to control academic and demographic factors. This dissertation focuses on two aspects : a measure of the student’s cognitive abilities at their entry in the university and a measure of their motivation during the course of the year. The results show that the school backg…
Post-flare Ultraviolet Light Curves Explained with Thermal Instability of Loop Plasma
2012
In the present work, we study the C8 flare that occurred on 2000 September 26 at 19:49 UT and observed by the Solar and Heliospheric Observatory/Solar Ultraviolet Measurement of Emitted Radiation spectrometer from the beginning of the impulsive phase to well beyond the disappearance in the X-rays. The emission first decayed progressively through equilibrium states until the plasma reached 2-3 MK. Then, a series of cooler lines, i.e., Ca X, Ca VII, Ne VI, O IV, and Si III (formed in the temperature range log T = 4.3-6.3 under equilibrium conditions), are emitted at the same time and all evolve in a similar way. Here, we show that the simultaneous emission of lines with such a different forma…
HNRNPR Variants that Impair Homeobox Gene Expression Drive Developmental Disorders in Humans
2019
The heterogeneous nuclear ribonucleoprotein (HNRNP) genes code for a set of RNA-binding proteins that function primarily in the spliceosome C complex. Pathogenic variants in these genes can drive neurodegeneration, through a mechanism involving excessive stress-granule formation, or developmental defects, through mechanisms that are not known. Here, we report four unrelated individuals who have truncating or missense variants in the same C-terminal region of hnRNPR and who have multisystem developmental defects including abnormalities of the brain and skeleton, dysmorphic facies, brachydactyly, seizures, and hypoplastic external genitalia. We further identified in the literature a fifth ind…

2022
El actual contexto educativo necesita una intensa alfabetización digital de todo el profesorado, lo que ha requerido una modificación significativa en los perfiles docentes convencionales. En el caso del profesorado especialista en Pedagogía terapéutica que trabaja con alumando con necesidades educativas especiales, la digitalización ha supuesto un desafío. Tales cambios han requerido dotarse de nuevas habilidades para transformar la información en conocimientos, guiar el proceso de enseñanza aprendizaje en un entorno novedoso y generar un espacio de inclusión educativa. El objetivo de esta investigación es identificar cuáles son los perfiles de los profesionales especialistas en Pedagogía …
Telpisko prasmju novērtēšanas testa digitālās versijas izstrāde
2021
Maģistra darbā izpētīta telpiskās uztveres un kognitīvo procesu teorija, kas ietver procesu komponentes, references ietvarus, telpiskās spējas, telpisko spēju pielietojumu dažādās nozarēs, telpisko spēju atšķirības starp dažādiem indivīdiem un informāciju par telpisko spēju novērtēšanu ar telpisko testu palīdzību. Pēc teorijas izpētes, tika izstrādāts telpisko prasmju novērtēšanas rīks, kas tika izmantots cilvēku testēšanai, lai noteiktu telpiskās spējas kontekstā ar izglītības un profesionālo nozaru virzienu, kur tās var būt noderīgas un pat nepieciešamas. Izmantojot izstrādāto telpisko spēju novērtēšanas rīku, tika ievākti dati un veikta iegūto rezultātu analīze, kā arī izdarīti secinājum…
On the use of ionic liquids as mobile phase additives in high-performance liquid chromatography. A review.
2015
The popularity of ionic liquids (ILs) has grown during the last decades in several analytical separation techniques. Consequently, the number of reports devoted to the applications of ILs is still increasing. This review is focused on the use of ILs (mainly imidazolium-based associated to chloride and tetrafluoroborate) as mobile phase additives in high-performance liquid chromatography (HPLC). In this approach, ILs just function as salts, but keep several kinds of intermolecular interactions, which are useful for chromatographic separations. Both cation and anion can be adsorbed on the stationary phase, creating a bilayer. This gives rise to hydrophobic, electrostatic and other specific in…
