Landis-type conjecture for the half-Laplacian

2023

In this paper, we study the Landis-type conjecture, i.e., unique continuation property from infinity, of the fractional Schrödinger equation with drift and potential terms. We show that if any solution of the equation decays at a certain exponential rate, then it must be trivial. The main ingredients of our proof are the Caffarelli-Silvestre extension and Armitage’s Liouville-type theorem. peerReviewed

Dyscalculia: Clinical manifestations, evaluation and diagnosis. Current Perspectives of educational intervention

2019

Learning difficulties and learning disorders are very frequent in schools nowadays, and they have been increasing in the field of mathematics. Such difficulties tend to be associated with other disorders such as dyslexia or Attention Deficit Hyperactivity Disorder (ADHD). The present article aims at deepening our understanding, definition and detection of dyscalculia, along with reviewing current educational treatments. Since 1990, concerns about learning difficulties in the classroom have been made explicit in policies such as the Spanish Law on the General Ordering of the Education System (LOGSE). Likewise, the indicators, symptoms, and prevalence of dyscalculia have been gathered since t…

Genetic and Biochemical Analysis of PadR-padC Promoter Interactions during the Phenolic Acid Stress Response in Bacillus subtilis 168

2011

ABSTRACT Bacillus subtilis 168 is resistant to phenolic acids by expression of an inducible enzyme, the phenolic acid decarboxylase (PadC), that decarboxylates these acids into less toxic vinyl derivatives. In the phenolic acid stress response (PASR), the repressor of padC , PadR, is inactivated by these acids. Inactivation of PadR is followed by a strong expression of padC . To elucidate the functional interaction between PadR and the padC promoter, we performed (i) footprinting assays to identify the region protected by PadR, (ii) electrophoretic mobility shift assays (EMSAs) with a modified padC promoter protected region to determine the interacting sequences, and (iii) random mutagenesi…

Characterization of the nucleation process of lysozyme at physiological pH: Primary but not sole process

2013

We report on a kinetic study of the heat-induced aggregation process of lysozyme at physiological pH. The time evolution of the aggregation extent and the conformational changes of the protein were followed by dynamic light scattering (DLS) and FTIR spectroscopy, respectively, whereas the morphology of the aggregates was observed by Atomic Force Microscopy (AFM). The conformational changes of the secondary and tertiary structures were simultaneous and distinct in time with respect to the formation of aggregates. Oligomer formation occurred through at least two different aggregation processes: a nucleation process and a homogeneous non-nucleative diffusion-controlled process. FTIR measuremen…

Yhteistyön mahdollisuudet – lukiokoulutukseen valmistava koulutus kielellistyvässä maailmassa

2018

Tassa tutkimuksessa selvitetaan sita, millaisia kasityksia rehtoreilla, opettajilla ja opiskelijoilla on vuorovaikutuksen mahdollistavasta toiminnasta eli yhteistyosta Lukiokoulutukseen valmistavan koulutuksen (LUVA) ja muun lukiotoiminnan valilla. Edellisen lisaksi tarkastellaan sita, ilmeneeko LUVA-koulutuksessa aineiston perusteella kielenoppimista tukevaa eri kielten limittaista kayttoa (engl.  translanguaging ).  Tutkimuksen teoreettinen tausta pohjautuu kielenoppimisen kayttopohjaiseen ajatteluun eli siihen, etta oppimisessa tarkeimpana nahdaan kielenkaytto ja vuorovaikutus. Taman artikkelin keskeinen teoreettinen kasite on  translanguaging , joka nahdaan vastakohtana yksikielisyyden …

Defending either a personal or an assigned standpoint

2018

Abstract This study clarifies whether a specific type of role play supports upper secondary school students’ collaborative argumentation. Data consist of 12 dyadic face-to-face and 12 chat debates. Data analysis focused on the quality of students’ argumentation. Comparisons were made between students who defended standpoints at variance with their personal opinions on the topics, between the two study modes and topics, and by gender. When the students defended a standpoint differing from their personal opinion, the male students engaged in counterargumentation more often than the female students. When, in turn, the students defended their personal standpoint, they produced both counterargum…

Immigrant status, gender, and school burnout in Finnish lower secondary school students : A longitudinal study

2017

The aim of this longitudinal study among 9223 students from grade 7 and grade 9 (age 13–14 and 15–16) was to assess whether immigrant status and gender are associated with the level and change (slope) in school burnout among lower secondary school students in the Helsinki metropolitan area. Ninety-seven percent of the variation in school burnout was attributable to individual factors. Both the intercept (2.3, p < 0.001) and slope (0.5, p < 0.001) of school burnout were statistically significant. The slope showed increasing school burnout from grades 7–9. School burnout increased more in girls than in boys. Initially apparent higher school burnout among students who had immigrated to …
