Self-knowledge, Authenticity and Obedience
2014
In questo articolo propongo un descrizione del privilegio epistemico dato alla prospettiva della prima persona, alla quale si relaziona un certo tipo di potere su sé stessi. Vorrei mettere in discussione il punto di vista di Robert Dumm e Richard Moran sul problema del soggetto e abbozzare un approccio alternativo. A tal fine, vorrei per prima cosa avvalermi delle nozioni di Bernard William di riconoscimento e di donazione di senso e, in secondo luogo, utilizzare la distinzione di Simone Weil tra i due sensi di obbedienza e la nozione, ad essa associata, di attenzione. In contrasto con la visione di Moran e Dunn, concluderei affermando che un certo tipo di autopercezione è centrale nel nost…

Mètode analític i transcendentalitat
2004
No tinc la seguretat que l'expressió «filosofia analítica» siga un rètol adient per a cap tendència, mètode o escola de l'activitat filosòfica. En un sentit molt general i potser trivial, encara que no n'estic cert, la filosofia és, del seu origen ençà, anàlisi: anàlisi del pensar i de l'ésser, i de les condicions de l'un i de l'altre. Tanmateix, només al nostre segle s'ha etiquetat una manera de fer filosofia com a «filosofia analítica», per motius no gaire clars.
Fona adaptācijas ietekme uz datorizētā krāsu sakārtošanas un FM-100 testa rezultātiem
2021
Šis darbs ir uzrakstīts angļu valodā uz 25 lappusēm, 16 attēliem, 1 tabulas un 27 atsaucēm. Gandrīz daudzi cilvēki cieš no iedzimta vai iegūta krāsu redzes deficīta. Tīklenē ir fotopigments, kas ir atbildīgs par krāsu redzi, ko sauc par konusu, kurā konusos esošajam opsinam ir izšķiroša nozīme krāsu uztverē, un viss mehānisms ir pabeigts smadzeņu pakauša daivā.

Contribution to variational analysis : stability of tangent and normal cones and convexity of Chebyshev sets
2014
The aim of this thesis is to study the following three problems: 1) We are concerned with the behavior of normal cones and subdifferentials with respect to two types of convergence of sets and functions: Mosco and Attouch-Wets convergences. Our analysis is devoted to proximal, Fréchet, and Mordukhovich limiting normal cones and subdifferentials. The results obtained can be seen as extensions of Attouch theorem to the context of non-convex functions on locally uniformly convex Banach space. 2) For a given bornology β on a Banach space X we are interested in the validity of the following "lim inf" formula (…).Here Tβ(C; x) and Tc(C; x) denote the β-tangent cone and the Clarke tangent cone to …
Cone-beam computed tomography in lung stereotactic ablative radiation therapy: predictive parameters of early response
2016
To analyze lung lesion volume variations by contouring on cone-beam CT (CBCT) images to evaluate the early predictive parameters of stereotactic ablative radiation therapy (SABR) treatment response.The prescribed dose of SABR was varied according to the tumour site (central or peripheral) and maximum diameter of the lesions by using a strategy of risk-adapted dose prescription with a dose range between 48 and 70 Gy in 3-10 consecutive fractions. For the purpose of the analysis, the gross tumour volume (GTV) was recontoured for each patient at first and last CBCT using two lung levels/windows: (a) -600/1000 HU and (b) -1000/250 HU. Univariate analysis was performed to evaluate a correlation …
LA PROPAGACIÓN DE LA NULIDAD EN EL ÁMBITO DE LA INFRACCIÓN DEL DERECHO DE LA COMPETENCIA
2019
El presente artículo tiene por finalidad analizar la propagación de la nulidad por infracción del Derecho de la Competencia. Para ello, tras analizar el fundamento de la nulidad, el trabajo analiza cómo la propagación de la nulidad no es la solución correcta en todos los contratos conexos. En algunos supuestos la solución será la indemnización de daños y perjuicios por infracción del Derecho de la Competencia ejercitada por el perjudicado frente a la empresa infractora, aunque no tenga relación contractual directa con ella, pero no la nulidad.
Invariant approximation results in cone metric spaces
2011
Some sufficient conditions for the existence of fixed point of mappings satisfying generalized weak contractive conditions is obtained. A fixed point theorem for nonexpansive mappings is also obtained. As an application, some invariant approximation results are derived in cone metric spaces.
Head-to-tail connected double calix[4]arenes
1997
New macrotricyclic compounds consisting of two calix[4]arene substructures connected by aliphatic chains of various length (three to five carbon atoms) between two oppositep-positions and two distal phenolic oxygens have been synthesized. Starting withp-tert-butyl-calix[4]arene, two O-protected phenolic units are attachedvia ether links in 1,3-position by reaction with the corresponding tosylates. After deprotection, the new calix[4]arene is formed by fragment condensation with 2,6-bisbromomethylated 4-alkylphenols. The structure of one example (8c) has been confirmed by single crystal X-ray analysis. Both calixarene parts assume the cone conformation, a molecule of acetonitrile being inclu…
Reversible Dimerization of Tetraureas Derived from Calix[4]Arenes
1999
Calix[4]arene derivatives, substituted at the wider rim by four urea functions are easily available in great variety. In apolar solvents like benzene or chloroform they dimerize via NH…O=C hydrogen bonds encapsulating a single solvent molecule as guest. The exclusive formation of dimers has been proved in solution by NMR, while their shape has been characterized by single crystal X-ray analysis. The kinetic stability and the rate of the guest exchange have been studied by NOESY experiments using a derivative with lower symmetry.
