Demonstration of remote optical measurement configuration that correlates to glucose concentration in blood
2010
An optical approach allowing the extraction and the separation of remote vibration sources has recently been proposed. The approach has also been applied for medical related applications as blood pressure and heart beats monitoring. In this paper we demonstrate its capability to monitor glucose concentration in blood stream. The technique is based on the tracking of temporal changes of reflected secondary speckle produced in human skin (wrist) when being illuminated by a laser beam. A temporal change in skin’s vibration profile generated due to blood pulsation is analyzed for estimating the glucose concentration. Experimental tests that were carried out in order to verify the proposed appro…
Toward fast malaria detection by secondary speckle sensing microscopy
2012
Diagnosis of malaria must be rapid, accurate, simple to use, portable and low cost, as suggested by the World Health Organization (WHO). Despite recent efforts, the gold standard remains the light microscopy of a stained blood film. This method can detect low parasitemia and identify different species of Plasmodium. However, it is time consuming, it requires well trained microscopist and good instrumentation to minimize misinterpretation, thus the costs are considerable. Moreover, the equipment cannot be easily transported and installed. In this paper we propose a new technique named "secondary speckle sensing microscopy" ((SM)-M-3) based upon extraction of correlation based statistics of s…
La necesidad de las cadenas de valor globales para evitar inercias cognitivas en clusters. El caso del valle del juguete-plástico en Alicante
2015
El objetivo del presente artículo se basa en entender la necesidad de la apertura de los clusters y su inclusión en cadenas de valor globales que permitan la entrada de conocimiento, la renovación de tecnologías y capacidades, la renovación de actores y, en definitiva, la mejora de la competitividad de los territorios y de sus tejidos productivos de pymes. Si bien ha predominado un paradigma de desarrollo local endógeno en los clusters o distritos industriales en toda la literatura, hecho totalmente evidente en la mayoría de los casos, la evidencia empírica de los últimos años comienza a desmitificar y moderar dicha característica que, si bien no deja de ser cierta, va perdiendo peso, sobre…

Ambidextrous Leadership, Social Entrepreneurial Orientation, and Operational Performance
2019
In the knowledge era, new forms of organizing and managing firms emerge to adapt to new situations. One such new form of organizational management is ambidextrous leadership. Ambidextrous leadership combines opening leader behaviors, such as promoting creativity, and closing leader behaviors, such as accomplishing objectives and adhering to norms. Thus, the aim is to demonstrate that a social orientation is not at odds with measures of operational performance other than profitability. The purpose of this study is to examine how ambidextrous leadership is linked to social entrepreneurial orientation and how this in turn affects operational performance. This is done through a rigorous review …
Nonlinear repolarization dynamics in optical fibers: transient polarization attraction
2011
International audience; In this work, we present a theoretical and experimental study of the response of a lossless polarizer to a signal beam with a time-varying state of polarization (SOP). By lossless polarizer, we mean a nonlinear conservative medium (e.g., an optical fiber) that is counterpumped by an intense and fully polarized pump beam. Such a medium transforms input uniform or random distributions of the SOP of an intense signal beam into output distributions that are tightly localized around a well-defined SOP. We introduce and characterize an important parameter of a lossless polarizer--its response time. Whenever the fluctuations of the SOP of the input signal beam are slower th…
Clinical evaluation of melanomas and common nevi by spectral imaging
2012
A clinical trial on multi-spectral imaging of malignant and non-malignant skin pathologies comprising 17 melanomas and 65 pigmented common nevi was performed. Optical density data of skin pathologies were obtained in the spectral range 450-950 nm using the multispectral camera Nuance EX. An image parameter and maps capable of distinguishing melanoma from pigmented nevi were proposed. The diagnostic criterion is based on skin optical density differences at three fixed wavelengths: 540nm, 650nm and 950nm. The sensitivity and specificity of this method were estimated to be 94% and 89%, respectively. The proposed methodology and potential clinical applications are discussed.
Process innovation objectives and management complementarities: patterns, drivers, co-adoption and performance effects
2012
[EN] The excessive concentration of the innovation literature on product development, its drivers and effects, has almost neglected an important strategy which develops and sustains a firm's competitive advantage: process development or innovation. This is an examination of process innovation as more than a mere dependent variable for predicting innovators. It provides insights into the poor attention that process innovation variable has received as an indicator of a firm's performance. In addition, the paper relates this process with the management innovation phenomenon. Using 8,977 firms from Spain through CIS data, findings suggest: (1) most process innovation performance is explained wi…
Application of the SKYRAD Improved Langley plot method for the in situ calibration of CIMEL Sun-sky photometers
2007
The in situ procedure for determining the solar calibration constants, originally developed for the PREDE Sun-sky radiometers and based on a modified version of the Langley plot, was applied to a CIMEL instrument located in Valencia, Spain, not integrated into AERONET. Taking into account the different mechanical and electronic characteristics of the two radiometers, the method was adapted to the characteristics of the CIMEL instrument. The iterative procedure for the determination of the solar calibration constants was applied to a 3-year data set. The results were compared with the two sets of experimental calibration constants determined during this period using the standard Langley plot…
