Solipsisme i trascendentalitat en el Tractatus

1986

Aquest article discuteix la interpretació kantiana del Tractatus, subratllant importants diferències entre els plantejaments de Kant i Wittgenstein i llurs concepcions de la lògica i de la transcendentalista. Es posa especial atenció en dues interpretacions kantianes del solipsisme wittgensteinià: la defensada per Hintikka i Maslow, i la defensada per David Favrholdt.

Subject, World and Value

2010

El punto de partida del artículo es el siguiente: Wittgenstein determinó su propósito de trazar un límite a la expresión lingüística del pensamiento sirviéndose, en cierta manera, de la distinción entre representación y voluntad con que Schopenhauer había reinterpretado la distinción kantiana entre el fenómeno y la cosa en sí. Al igual que Schopenhauer, Wittgenstein sostiene que el mundo de la ciencia corresponde al fenómeno, al mundo como ‘representación’, al mundo de los hechos; e igualmente considera que todo cuanto tiene que ver con los asuntos de máxima importancia y valor para nosotros —el sentido de nuestra existencia o de la existencia del mundo, la relación entre el sujeto de la vo…

Field-free two-direction alignment alternation of linear molecules by elliptic laser pulses

2005

We show that a linear molecule subjected to a short specific elliptically polarized laser field yields postpulse revivals exhibiting alignment alternatively located along the orthogonal axis and the major axis of the ellipse. The effect is experimentally demonstrated by measuring the optical Kerr effect along two different axes. The conditions ensuring an optimal field-free alternation of high alignments along both directions are derived.

Robust control in uncertain multi-inventory systems and consensus problems

2008

Abstract We consider a continuous time linear multi–inventory system with unknown demands bounded within ellipsoids and controls bounded within polytopes. We address the problem of ∈-stabilizing the inventory since this implies some reduction of the inventory costs. The main results are certain conditions under which ∈-stabilizability is possible through a saturated linear state feedback control. The idea of this approach is similar to the consensus problem solution for a network of continuous time dynamic agents, where each agent evolves according to a first order dynamics has bounded control and it is subject to unknown but bounded disturbances. In this context, we derive conditions under…

Pulmonary surfactant protein C containing lipid films at the air-water interface as a model for the surface of lung alveoli.

1995

The pulmonary surfactant lines as a complex monolayer of lipids and proteins the alveolar epithelial surface. The monolayer dynamically adapts the surface tension of this interface to the varying surface areas during inhalation and exhalation. Its presence in the alveoli is thus a prerequisite for a proper lung function. The lipid moiety represents about 90% of the surfactant and contains mainly dipalmitoylphosphatidylcholine (DPPC) and phosphatidylglycerol (PG). The surfactant proteins involved in the surface tension adaption are called SP-A, SP-B and SP-C. The aim of the present investigation is to analyse the properties of monolayer films made from pure SP-C and from mixtures of DPPC, DP…

Recombinant activated factor VII administration in a patient with congenital lack of factor VII undergoing laparoscopic hysterectomy: A case report

2021

Highlights • Patients with lack of factor VIIa, suffering from abnormal uterine bleedings can be treated with laparoscopic hysterectomy. • Technique using bipolar coagulation and non-absorbable clips is safe and not time consuming. • Pre-operative loading with recombinant factor VIIa must be followed by prolonged supplementation in post-operative period. • We present suggested dosage and length of factor VIIa supplementation based on literature review and own experience.

Quantitative uniqueness estimates for pp-Laplace type equations in the plane

2016

Abstract In this article our main concern is to prove the quantitative unique estimates for the p -Laplace equation, 1 p ∞ , with a locally Lipschitz drift in the plane. To be more precise, let u ∈ W l o c 1 , p ( R 2 ) be a nontrivial weak solution to div ( | ∇ u | p − 2 ∇ u ) + W ⋅ ( | ∇ u | p − 2 ∇ u ) = 0  in  R 2 , where W is a locally Lipschitz real vector satisfying ‖ W ‖ L q ( R 2 ) ≤ M for q ≥ max { p , 2 } . Assume that u satisfies certain a priori assumption at 0. For q > max { p , 2 } or q = p > 2 , if ‖ u ‖ L ∞ ( R 2 ) ≤ C 0 , then u satisfies the following asymptotic estimates at R ≫ 1 inf | z 0 | = R sup | z − z 0 | 1 | u ( z ) | ≥ e − C R 1 − 2 q log R , where C > 0 depends …

Polarization tensors of planar domains as functions of the admittivity contrast

2014

(Electric) polarization tensors describe part of the leading order term of asymptotic voltage perturbations caused by low volume fraction inhomogeneities of the electrical properties of a medium. They depend on the geometry of the support of the inhomogeneities and on their admittivity contrast. Corresponding asymptotic formulas are of particular interest in the design of reconstruction algorithms for determining the locations and the material properties of inhomogeneities inside a body from measurements of current flows and associated voltage potentials on the body's surface. In this work we consider the two-dimensional case only and provide an analytic representation of the polarization t…

Bounded Palais–Smale sequences for non-differentiable functions

2011

The existence of bounded Palais-Smale sequences (briefly BPS) for functionals depending on a parameter belonging to a real interval and which are the sum of a locally Lipschitz continuous term and of a convex, proper, lower semicontinuous function, is obtained when the parameter runs in a full measure subset of the given interval. Specifically, for this class of non-smooth functions, we obtain BPS related to mountain pass and to global infima levels. This is done by developing a unifying approach, which applies to both cases and relies on a suitable deformation lemma. © 2011 Elsevier Ltd. All rights reserved.

Ellipsis in Finnish Sign Language

2013

This paper deals with syntactic ellipsis in clauses in Finnish Sign Language (FinSL). The point of departure for the paper is the observation, confirmed by several studies, that clauses in FinSL are often syntactically incomplete. Building on this, the paper first describes how all core-internal clausal material may be elided in FinSL: core arguments in clauses with a verbal nucleus, core-internal NPs in clauses with a nominal nucleus, and even nuclei themselves. The paper then discusses several grammatical contexts which especially favor ellipsis in FinSL. These are question–answer pairs, two-clause coordinated structures, topic–comment structures, blend structures, and structures containi…
