Peripersonal Visuospatial Abilities in Williams Syndrome Analyzed by a Table Radial Arm Maze Task
2020
Williams syndrome (WS) is a genetic deletion syndrome characterized by severe visuospatial deficits affecting spatial exploration and navigation abilities in extra-personal space.To date, little is known about spatial elaboration and reaching abilities in the peripersonal space in individuals with WS. The present study is aimed at evaluating the visuospatial abilities in individuals with WS and comparing their performances with those of mental age-matched typically developing (TD) children by using a highly sensitive ecological version of the Radial Arm Maze (table RAM). We evaluated 15 individuals with WS and 15 TD children in two different table RAM paradigms: the free-choice paradigm, ma…

Impacto de las técnicas de reconstrucción multicapa vascularizadas en la cirugía endoscópica endonasal de base de cráneo
2015
Los abordajes endonasales endoscópicos expandidos (AEEE) son un conjunto de técnicas quirúrgicas, completamente endoscópicas, mediante las cuales se abordan lesiones de la base craneal a través del corredor anatómico que supone la cavidad nasal y senos paranasales. Las técnicas reconstructivas inicialmente utilizadas en el cierre de defectos generados tras AEEE, estuvieron basadas en la experiencia previa acumulada con las reparaciones endoscópicas de fístulas de LCR. Múltiples estudios han validado que las pequeñas fístulas de LCR pueden ser reconstruidas con una amplia variedad de injertos libres como hemos visto en apartados anteriores, alcanzado del cierre con éxito en el 95% de los pac…
Identifying the Neurocognitive bases of creativity to increase human and computational creativity
2022
En esta Tesis Doctoral se ha identificado la estructura neurocognitiva que sustenta la creatividad humana a partir del análisis conjunto de más de 800 referencias bibliográficas que muestran las investigaciones más importantes realizadas hasta la fecha. Sobre la base de esta estructura, se ha identificado un paradigma neurocognitivo de la creatividad humana y se ha propuesto un modelo neurocognitivo del proceso creativo. Finalmente, también se ha propuesto un paradigma creativo neurocognitivo computacional y se ha diseñado la estructura de un sistema computacional creativo, basado en una estructura multiagente. La investigación que se ha realizado sobre el tema hasta la fecha es muy especia…
Haha moments : applying brain research to technology design
2018
Mood problems are very damaging and far-reaching, affecting millions of people worldwide. More attempts should have been made by design researchers to form innovative and feasible design concepts, against current technological background, to produce practical technical artifacts to solve the issue. This monograph focuses on Design Science research and its collaboration with Neuroscience to seek ways to help people with negative moods, depression in particular. Humor, exerting positive influences on both physical and mental health and impacting every aspect concerning social interactions, is worth investigating. Studies on the cognitive processing mechanism of humor appreciation provide know…
Long-baseline neutrino oscillation physics potential of the DUNE experiment
2020
The sensitivity of the Deep Underground Neutrino Experiment (DUNE) to neutrino oscillation is determined, based on a full simulation, reconstruction, and event selection of the far detector and a full simulation and parameterized analysis of the near detector. Detailed uncertainties due to the flux prediction, neutrino interaction model, and detector effects are included. DUNE will resolve the neutrino mass ordering to a precision of 5σσ, for all δCPδCP values, after 2 years of running with the nominal detector design and beam configuration. It has the potential to observe charge-parity violation in the neutrino sector to a precision of 3σσ (5σσ) after an exposure of 5 (10) years, for 50% o…
Acidity and basicity of primaryN-phenylnitramines: catalytic effect of protons on the nitramine rearrangement
2002
Para-substituted N-phenylnitramines were prepared either by oxidation of diazonium salts or by nitration under alkaline or acidic conditions. Isotopic [15N-NO2] labelling indicated that the bands characteristic of the N-nitro group appear in the 1318–1323 and 1585–1607 cm−1 regions. In the nitrogen NMR spectra, the nitramino group gives two resonances at −193 ± 3 (NH) and −32 ± 3 ppm (NO2). The chemical shifts in proton and carbon NMR spectra are predictable, based on increments and the additivity rule. The spectral data indicate the lack of conjugation between the nitramino group and another substituent bound to the ring. It seems to contradict the well-known fact that substituents strongl…
Apolar versus polar solvents: a comparison of the strength of some organic acids against different bases in toluene and in water
2010
The constants of ion-pair formation with 3-nitroaniline (3NO(2)A) for eight halogenoacetic acids (HAAs, 3a-h: TFA, TCA, TBA, DFA, DCA, DBA, MCA, and MBA), and five 2,2-dichloroalkanoic acids containing 3-8 carbon atoms (HAs, 5a-e: DCPA, DCBA, DCMBA, DCVA, and DCOA) have been determined in TOL at 298.1 K. The results obtained brought to evidence for HAAs the formation of ion-pairs with two different stoichiometries (base-acid, 1:1 or 1:2), while in contrast the HAs furnish only the 1:1 pairs. The different steric and electronic requirements of HAAs and HAs seem to be responsible for such an unlikely behavior. At the same time, the acid-catalyzed MRH of the (Z)-phenylhydrazone of 5-amino-3-be…
Glaciolimniskie nogulumi Lielauces-Zebrenes glaciodepresijā
2015
Maģistra darbā “Glaciolimniskie nogulumi Lielauces – Zebrenes glaciodepresijā” raksturota Lielauces – Zebrenes glaciodepresijā sastopamo glaciolimnisko nogulumu daudzveidība un to saguluma apstākļi, kā arī sniegta šo nogulumu veidošanās apstākļu interpretācija. Pētījumā izmantotās metodes ietver lauka apsekojumus, ģeoloģisko urbšanu un nogulumu atsegumu fotodokumentēšanu. Savukārt laboratorijā veiktas nogulumu granulometriskā sastāva analīzes. Maģistra darba ietvaros analizēts arī virsmas reljefs glaciolimnisko nogulumu izplatības apvidū, kas ļauj izdarīt secinājumus par nogulumu veidošanās apstākļiem.
