Nietzsche, intérprete de Schopenhauer. La rosa y el crisantemo.
1990
Presentación, con textos y comentarios, de la imagen doble que presenta la figura y la obra del filósofo A. Schopenhauer en los textos de F. Nietzsche.
Sobre lo trágico en Schopenhauer y Nietzsche
2000
Es evidente que hablar de lo tragico es, ante todo, hablar de la tragedia atica. Hacerlo con fundamento implica, siempre, referirse de algun modo a lo que se nos ha conservado de los dramaturgos griegos que cultivaron ese inconfundible genero que ya merecio un notable tratamiento por parte de las reflexiones poeticas de Aristoteles. Es obvio, pues, que sean los filologos clasicos y los filosofos preocupados por las cuestiones de estetica quienes, en principio, mas legitimados se hallen a la hora de esclarecernos que sea eso a lo que llamamos lo “tragico”. Ahora bien, este sindrome tan complejo y de calado antropologico tan esencial implica fuertes dificultades y compromisos en todo aquel qu…
Buscando espacios para la verdad: Nietzsche y la filosofía en la Universidad
2008
Como hizo Nietzsche cuando reflexionó sobre la universidad, partiremos también de los recuerdos y experiencias de nuestra propia vida universitaria, para poder así, dialogando con los suyos y con las meditaciones que le proporcionaron, tratar de aprender alguna lección vital.
Quantum-chemical determination of Born–Oppenheimer breakdown parameters for rotational constants: the open-shell species CN, CO+ and BO
2013
The quantum-chemical protocol for computing Born-Oppenheimer breakdown corrections to rotational constants in the case of diatomic molecules is extended to open-shell species. The deviation from the Born-Oppenheimer equilibrium rotational constant is obtained by considering three contributions: the adiabatic correction to the equilibrium bond distance, the electronic contribution to the moment of inertia requiring the computation of the rotational g-tensor, and the so-called Dunham correction. Values for the Born-Oppenheimer breakdown parameters of CN, CO+, and BO in their (2)sigma(+) electronic ground states are reported based on coupled-cluster calculations of the involved quantities and …
Design exploration of aes accelerators on FPGAS and GPUs
2017
The embedded systems are increasingly becoming a key technological component of all kinds of complex tech-nical systems and an exhaustive analysis of the state of the art of all current performance with respect to architectures, design methodologies, test and applications could be very in-teresting. The Advanced Encryption Standard (AES), based on the well-known algorithm Rijndael, is designed to be easily implemented in hardware and software platforms. General purpose computing on graphics processing unit (GPGPU) is an alternative to recongurable accelerators based on FPGA devices. This paper presents a direct comparison between FPGA and GPU used as accelerators for the AES cipher. The res…
An improvement of ComiR algorithm for microRNA target prediction by exploiting coding region sequences of mRNAs
2020
AbstractMicroRNA are small non-coding RNAs that post-transcriptionally regulate the expression levels of messenger RNAs. MicroRNA regulation activity depends on the recognition of binding sites located on mRNA molecules. ComiR is a web tool realized to predict the targets of a set of microRNAs, starting from their expression profile. ComiR was trained with the information regarding binding sites in the 3’utr region, by using a reliable dataset containing the targets of endogenously expressed microRNA in D. melanogaster S2 cells. This dataset was obtained by comparing the results from two different experimental approaches, i.e., inhibition, and immunoprecipitation of the AGO1 protein--a comp…
Genetic organization of the citCDEF locus and identification of mae and clyR genes from Leuconostoc mesenteroides.
1999
ABSTRACT In this paper, we describe two open reading frames coding for a NAD-dependent malic enzyme ( mae ) and a putative regulatory protein ( clyR ) found in the upstream region of citCDEFG of Leuconostoc mesenteroides subsp. cremoris 195. The transcriptional analysis of the citrate lyase locus revealed one polycistronic mRNA covering the mae and citCDEF genes. This transcript was detected only on RNA prepared from cells grown in the presence of citrate. Primer extension experiments suggest that clyR and the citrate lyase operon are expressed from a bidirectional A-T-rich promoter region located between mae and clyR.

Conformational Properties of Nickel(II) Octaethylporphyrin in Solution. 2. A Low-Temperature Optical Absorption Spectroscopy Study
1996
We have measured the absorption spectrum of Ni(II) octaethylporphyrin in CH2Cl2 and in a 50% v/v isopentane/ethyl ether mixture as a function of temperature between 150 and 300 K and 40 and 300 K, respectively. The Soret band can be decomposed into two subbands whose frequencies differ by 220 cm-1. By analogy with resonance Raman results (Jentzen et al. J. Phys. Chem. 1996, 100, 14184−14191 (preceding paper)), we attribute the low-frequency subband to a conformer with a nonplanar macrocycle structure, whereas the high-frequency subband is interpreted as resulting from a planar conformer. The subbands' intensity ratios exhibit a solvent-dependent van't Hoff behavior between 300 and 160 K. Cr…
Remembrance of the historian Vicent Llombart
2017
Esta evocación muestra cómo la formación inicial que recibió Vicent Llombart en el Seminario de historia del pensamiento económico en la Universidad de Valencia fue decisiva, pero no suficiente, para entender una trayectoria rotunda por sus contribuciones. Su propósito decidido, su firme exigencia personal y su apertura intelectual permanente nos ayudan a comprender mejor a un gran historiador. This remembrance shows how the initial training that Vicent Llombart received at the Seminar on the History of Economic Thought at the University of Valencia was crucial, although not the only element, to understanding a prominent academic career with so relevant contributions. His determined purpose…
