NEAR INFRARED PICOSECOND PULSED BACKWARD SECOND-HARMONIC-GENERATION IN PERIODICALLY-POLED LITHIUM NIOBATE
2011
We report on backward second-harmonic-generation in bulk periodically-poled congruent lithium niobate with a 3.2μm period. A picosecond pulsed laser allowed us exciting a resonance at 1722nm. The resonances were also resolved by temperature tuning.
Heat shock response in yeast involver changes in both transcription rates and mRNA stabilities
2011
We have analyzed the heat stress response in the yeast Saccharomyces cerevisiae by determining mRNA levels and transcription rates for the whole transcriptome after a shift from 25uC to 37uC. Using an established mathematical algorithm, theoretical mRNA decay rates have also been calculated from the experimental data. We have verified the mathematical predictions for selected genes by determining their mRNA decay rates at different times during heat stress response using the regulatable tetO promoter. This study indicates that the yeast response to heat shock is not only due to changes in transcription rates, but also to changes in the mRNA stabilities. mRNA stability is affected in 62% of …
A Novel Approach for Faulty Sensor Detection and Data Correction in Wireless Sensor Network
2013
he main Wireless Sensor Networks purpose is represented by areas of interest monitoring. Even if the Wireless sensor network is properly initialized, errors can occur during its monitoring tasks. The present work describes an approach for detecting faulty sensors in Wireless Sensor Network and for correcting their corrupted data. The approach is based on the assumption that exist a spatio-temporal cross- correlations among sensors. Two sequential mathematical tools are used. The first stage is a probabilistic tools, namely Markov Random Field, for a two-fold sensor classification (working or damaged). The last stage is represented by the Locally Weighted Regression model, a learning techniq…
Inversion formulae for the integral transform on a locally compact zero-dimensional group
2009
Abstract Generalized inversion formulae for multiplicative integral transform with a kernel defined by characters of a locally compact zero-dimensional abelian group are obtained using a Kurzweil-Henstock type integral.
On continua comparable with all continua
1999
Abstract A collection of continua is described such that each continuum either is incomparable with some element of the collection, or it is a continuous image of the harmonic fan. As a consequence, a characterization of continua comparable with all continua is obtained.
Finitary unification in locally tabular modal logics characterized
2022
We provide necessary and sufficient conditions for finitary unification in locally tabular modal logics, solely in terms of Kripke models. We apply the conditions to establish the unification types of logics determined by simple finite frames. In particular, we show that unification is finitary (or unitary) in the logic determined by the fork (frame F4, see Fig. 6), the rhombus (frame F5), inGL.3m,GrzBd2,S4Bd2and other logics; whereas it is nullary in the logic of F6, and of the pentagon FN5. In Appendix analogous results are given for superintuitionistic logics.
Is recursion language-specific? Evidence of recursive mechanisms in the structure of intentional action
2014
In their 2002 seminal paper Hauser, Chomsky and Fitch hypothesize that recursion is the only human-specific and language-specific mechanism of the faculty of language. While debate focused primarily on the meaning of recursion in the hypothesis and on the human-specific and syntax-specific character of recursion, the present work focuses on the claim that recursion is language-specific. We argue that there are recursive structures in the domain of motor intentionality by way of extending John R. Searle's analysis of intentional action. We then discuss evidence from cognitive science and neuroscience supporting the claim that motor-intentional recursion is language-independent and suggest so…

2020
Luce da Luce φῶς ἐκ φωτός – Luce su Luce (Nūr ‘alà Nūr) è un progetto che mira a individuare elementi che possano permettere la comparazione tra cultura, tradizione, ritualità ed aspetti religiosi della Cristianità ortodossa e bizantina e la dimensione più mistica e interiore dell’Islam. Durante le giornate studiosi, artisti e teologi si sono confrontati sul tema i cui contributi sono raccolti nel volume di atti. Luce da Luce φῶς ἐκ φωτός - Light on Light (Nūr 'alà Nūr) is a project that aims to identify elements that can allow the comparison between culture, tradition, rituality and religious aspects of Orthodox and Byzantine Christianity and the more mystical and interior dimension of Isl…
Pyramidal and nonpyramidal callosal cells in the striate cortex of the adult rat
1994
The aim of this study has been to determine the neuronal types (pyramidal and nonpyramidal) within the rat's visual cortex, which project through the corpus callosum. To this end, the morphology and laminar distribution of callosal cells have been investigated by combining Diamidino Yellow retrograde tracing with intracellular injection of Lucifer Yellow in slightly fixed tissue slices. The visual callosal projection arises from pyramidal cells of diverse morphology in layers II to VIb, as well as from several modified pyramids located mainly in layers II, IV (star pyramids) and VIb (horizontal or inverted pyramids and related forms of spiny stellate cells). Our results indicate that in rat…
Lower-Extremity Blocks
1988
Operations on the lower extremities are commonly performed with either subarachnoid or epidural block. Although conduction anesthesia has a high rate of success and is relatively easy to perform, subarachnoid or epidural procedures may not be indicated for certain groups of patients, including the elderly, debilitated, arthritic, obese, or critically ill. With such patients, lowerextremity regional anesthesia can be accomplished by blocking the lumbosacral plexus or its branches.
