La Evaluación de proyectos con impacto ambiental. Eficiencia y sostenibilidad (2007)

Suele darse por sentado que la valoración de los impactos que recaen sobre las generaciones presentes no comporta dificultad alguna. Sin embargo esto no es cierto. Es más, no se dispone de una metodología ampliamente aceptada para contabilizar dichos impactos. Algunos de los aspectos más controvertidos son: la elección del valor apropiado para la tasa de descuento, las unidades -físicas o monetarias- en que deben expresarse los flujos y la valoración de los bienes tangibles e intangibles. Cuando existen impactos a muy largo plazo surge el problema de valorar los costes y beneficios que afectan a las generaciones futuras mediante, por ejemplo, una tasa de descuento intergeneracional. Incluso en este último caso estaría dominando la perspectiva de las generaciones presentes, que actuarían como si poseyeran la totalidad de los derechos de propiedad sobre todos los recursos. Por lo tanto es necesario incorporar el requisito de sostenibilidad en el análisis. En este trabajo se examinan algunos de estos aspectos y se proponen vías de solución.
The structure of the limit cycles in sigma delta modulation (1988)

It is shown that when the input to a sigma-delta modulator is a DC level that can be expressed as a rational number b/a, when normalized with respect to the quantizer step, the output bit string is periodic with a period that is multiple of the denominator a. On the basis of number theory, the structure of these cycles for single-loop modulators is determined and the noise contribution is computed. Around such levels the noise has two peaks, for which the maximum value and the width are proportional to the relative signal bandwidth and to the inverse of the period of the cycle, respectively. The effect of the limit cycles on the performance of the A/D and D/A converters using sigma-delta modulation is discussed. A comparison between single-loop and double-loop modulators from the point of view of this phenomena is made.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
A GPS-free power grid monitoring system over mobile platforms (2015)

In smart grids, the deviation of frequency and phase angle serves as an important indicator of abnormal events, the detection of which is critical to maintain reliable and stable operations of the power grid. However, the high cost and low accessibility of current power grid monitoring systems restrict their large-scale deployment over highly distributed microgrids. In this paper, we present a practical frequency and phase angle monitoring system design over mobile platforms, which significantly reduces the cost of power grid monitoring by utilizing the functionalities of modern mobile devices. We harvest the 200 Hz Primary Synchronization Signal (PSS) embedded in the 4G Long Term Evolution (LTE) cellular signal for time synchronization in power grid monitoring, replacing the Pulse-Per-Second (PPS) signal that is retrieved from GPS receivers and being used by current monitoring systems. We implement our system over realistic smartphones with a few peripheral hardware, and realize a frequency monitoring accuracy of 0.2 mHz and a phase angle monitoring accuracy of 0.01 rad. Experiment results compared with the traditional Frequency Disturbance Recorders (FDRs) verify the effectiveness of our proposed system.
Maternal-neonatal interactions and human breast milk. (1981)

The mammary glands are a uniquely designed extension of the mucosal immune systems of the gut and bronchus. The soluble and cellular products of lactation, in which immunologic selectivity and specificity exist, link the suckling neonate irrevocably to the immunologic and infectious experience of its mother. The immune competence of the breast and products of lactation are actively and constantly in flux, dependent on the mother's hormonal, environmental, and immunologic milieu. Most of the recent human investigation has focused primarily on milk immunoglobulin specificity. More work needs to be done on the role of passively transferred cellular products, the antiviral, antiprotozoan, and antitumor capabilities of milk, and on the mechanisms by which maternal immunizations or infections may influence the outcome of host-pathogen interactions in the suckling neonate.
Immune Responses to Insulin Aspart and Biphasic Insulin Aspart in People With Type 1 and Type 2 Diabetes (2002)

Treatment with IAsp is associated with an increase in cross-reactive insulin antibodies, with a subsequent fall toward baseline values, without any indication of clinical relevance because no effect on efficacy or safety could be identified.

At the crossroads of ubiquitin signaling and mass spectrometry (2010)

Ubiquitin signaling regulates a wide variety of cellular events, although it is mostly known to mediate protein degradation by the proteasome complex. The rapid development in mass spectrometry offers state-of-the-art technologies for addressing biological challenges in ubiquitin signaling. The First Conference on Proteomics of Protein Degradation & Ubiquitin Pathways in Vancouver, Canada, covers the latest progress in key topics of the field and fosters collaborative interactions among researchers.
Dual role of LiF as a hole-injection buffer in organic light-emitting diodes (2004)

It is demonstrated experimentally that the effect of a LiF buffer layer inserted at the ITO\N,N′-bis(1-naphthyl)-N,N′-diphenyl-1,1′ biphenyl 4,4′-dimaine (NPB) interface on the hole injection is greatly dependent on the initial barrier height (IBH) existing at the interface. Only for a large IBH, will the introduction of the LiF show improvement effect. For small one, it will weaken the hole injection. These phenomena are explained in terms of tunneling model and calculations based on this model show a good agreement with the experimental results. This further confirms that the energy level realignment and the change in carrier tunneling probability are mainly responsible for the variation of current injection induced by the insulating buffers in organic light-emitting diodes.
Applicability of random primer R143 for determination of<i>Aspergillus fumigatus</i>DNA (1997)

The specificity of random primer R143 for Aspergillus fumigatus DNA was determined in order to test its usefulness in establishing the presence of A. fumigatus DNA in fungal cultures. When PCR reaction products of these cultures were compared with those of 21 other bacterial and fungal DNA samples, R143 proved to produce a 1346 bp band with only A. fumigatus. This band has been sequenced completely and the EcoRI restriction site was used for subsequent confirmation of PCR products. The specificity for A. fumigatus DNA was also confirmed by Southern blotting. Comparison of morphological typing of Aspergillus species in cultures with PCR using R143 on DNA isolated from these cultures showed concordance in 22 of 24 cases. In two cases there was discordance: both times PCR results showed correctly the presence of A. fumigatus, initially not detected by culture. R143 is an A. fumigatus specific random primer, with potential for use in detection of A. fumigatus DNA in clinical specimens.
The importance of values in the coaching process (2004)

The subject of this paper is values in coaching and their role in the coaching process; I will address most of my remarks specifically to the coaching of children.My purpose is to encourage coaches to develop a personal philosophy of coaching that emphasises the well-being of the children under their care.Children are vulnerable to a variety of adult infiuences and sport provides many opportunities for them to be exploited to meet the needs of other people, even to the extent of child abuse (se e for example, Ryan, 1995).For children to get the most out of the sporting experience coaches need to consider carefully how they can best serve primarily the needs of the children while at the sam e time meeting their own needs and those of the sport and clubs which they represent.Naturally there is a potential for considerable confiict here since the young athletes, coaches, clubs, sport governing bodies, and parents may ali have differing ideas about the purposes of sport and the desirability of specific practices.You may have asked yourselves why we provide sport for children.If so, you have probably also asked why you are part of the processo These questions are very important because coaching children is a great responsibility.Coaches have a great impact not only on how children experience sport but also because children's attitudes, toward both themselves and the world, are not fixed but still forming, and coaches have an effect on their development.Knowing clearly what part you are going to play in providing sport experiences for children is a matter of having a personal philosophy, a set of 82 values which guides the things you do to present the sport to the children you coach.You need to be aware of what it is that you are really trying to do, and that it fits what the children need and want. Patterns of growth and participation in youth sportPopulation changes and participation patterns among children affect how sports federations promote their own sports and retain the interest of young people.They also raise questions about the role that sport plays in children's lives and who are the main beneficiaries of youth sport programmes.
Toxic shock syndrome Staphylococcus aureus: effect of tampons on toxic shock syndrome toxin 1 production. (1984)

Tampons were tested for effect on growth and production of toxic shock syndrome toxin 1 by Staphylococcus aureus. Under good growth conditions, regular absorbency tampons had little effect on bacterial growth and inhibited toxin production two- to fourfold. In contrast, higher absorbency tampons had three different effects: 1) some tampons had no effect on bacterial growth but inhibited toxin production; 2) many tampons inhibited both growth and toxin production; 3) one tampon inhibited growth but increased exotoxin per cell. These effects were independent of degree of saturation of the tampons and were observed at incubation times of six, 12, and 18 hours. In no instance was the production of toxic shock syndrome toxin 1 per milliliter increased in the presence of tampons when compared with control.
Low-Power Analog Processing for Sensing Applications: Low-Frequency Harmonic Signal Classification (2013)

A low-power analog sensor front-end is described that reduces the energy required to extract environmental sensing spectral features without using Fast Fouriér Transform (FFT) or wavelet transforms. An Analog Harmonic Transform (AHT) allows selection of only the features needed by the back-end, in contrast to the FFT, where all coefficients must be calculated simultaneously. We also show that the FFT coefficients can be easily calculated from the AHT results by a simple back-substitution. The scheme is tailored for low-power, parallel analog implementation in an integrated circuit (IC). Two different applications are tested with an ideal front-end model and compared to existing studies with the same data sets. Results from the military vehicle classification and identification of machine-bearing fault applications shows that the front-end suits a wide range of harmonic signal sources. Analog-related errors are modeled to evaluate the feasibility of and to set design parameters for an IC implementation to maintain good system-level performance. Design of a preliminary transistor-level integrator circuit in a 0.13 µm complementary metal-oxide-silicon (CMOS) integrated circuit process showed the ability to use online self-calibration to reduce fabrication errors to a sufficiently low level. Estimated power dissipation is about three orders of magnitude less than similar vehicle classification systems that use commercially available FFT spectral extraction.

Flow cytometric HLA‐B27 screening: Cross‐reactivity patterns of commercially available anti–HLA‐B27 monoclonal antibodies with other HLA‐B antigens (2003)

All mAbs tested showed cross-reactivity, ranging from weak (+/-) to strong (+), with different antigens and different degrees of intensity-ABC-m3: (+/-) B12, B16, B17, B41, B47, and B48 and (+) B7, B13, B22, B37, B40, and B42; GS145.2: (+/-) B13, B17, B22, B40, and B47 and (+) B7, B16, B37, B42, and B48; FD705: (+/-) B12, B13, B16, and B48 and (+) B17, B37, and B47. If one mAb had been used for HLA-B27 screening, ABC-m3 would have yielded nine false-positive B27 assignments, FD705 would have yielded seven, and GS145.2 would have yielded two. This problem largely canbe avoided by the combined use of two different mAb clones. The combination of FD705 and GS145.2 yielded the best results, with one false-positive HLA-B27 assignment among the 99 HLA-B27(-) samples of this highly selected panel.
Structure of the Gene for the Arylphorin-type Storage Protein SP 2 of Bombyx mori (1989)

Two forms of storage proteins termed "SP 1" and "SP 2", respectively, accumulate in a stage-dependent fashion in the larval hemolymph of the silkworm Bombyx mori. We have cloned and analyzed the genomic sequence encoding SP 2, an arylphorin-type storage protein. The SP 2 structural gene contains five exons spanning over 5 kilobases of chromosomal DNA. The transcription initiation site of the SP 2 gene was identified at the nucleotide level and a typical TATA box was located 30 base pairs upstream of the transcription initiation site. The 5'-flanking region of the gene contains a sequence homologous to the SV 40 enhancer "core" structure. A region homologous to the Drosophila enhancer sequence predicted for the fat body specificity of gene expression exists in the 5'-upstream region. Developmental profiles of the SP 2 mRNA and its precursor in the fat body indicate that the biosynthesis of SP 2 is developmentally regulated at the level of transcription. The exon/intron composition of the SP 2 gene is remarkably similar to that of the SP 1 gene. Moreover, the deduced primary structures of SP 1 and SP 2 exhibit nearly 30% homology, implying that two storage protein genes of the B. mori silkworm might have evolved from a common ancestor.

The implementation of digital audio processors in analog multimedia audio systems (2004)

A remarkable pace at which communication technology is developing has put new demands on audio/video conference and distance learning systems. In response to such requirements, digital technology has been increasingly introduced into the audio component of these systems, namely digital audio mixers and signal processors. They are being integrated into multimedia systems using various communication protocols, and controlled via central processing units and control consoles and panels. However, by simply integrating digital control systems into the already existing analog equipment it is possible to make the most of it, both financially and technologically. This article gives a brief account of such an analog but digitally controlled audio system within a multimedia conference room.
Optical forces in nanowire pairs and metamaterials (2010)

We study the optical force arising when isolated gold nanowire pairs and metamaterials with a gold nanowire pair in the unit cell are illuminated with laser radiation. Firstly, we show that isolated nanowire pairs are subject to much stronger optical forces than nanospheres due to their stronger electric and magnetic dipole resonances. We also investigate the properties of the optical force as a function of the length of the nanowires and of the distance between the nanowires. Secondly, we study the optical force in a metamaterial that consists of a periodic array of nanowire pairs. We show that the ratio of the size of the unit cell to the length of the nanowires determines whether the electric dipole resonance leads to an attractive or a repulsive force, and we present the underlying physical mechanism for this effect.
On Realistic Target Coverage by Autonomous Drones (2019)

Low-cost mini-drones with advanced sensing and maneuverability enable a new class of intelligent sensing systems. To achieve the full potential of such drones, it is necessary to develop new enhanced formulations of both common and emerging sensing scenarios. Namely, several fundamental challenges in visual sensing are yet to be solved including (1) fitting sizable targets in camera frames; (2) positioning cameras at effective viewpoints matching target poses; and (3) accounting for occlusion by elements in the environment, including other targets. In this article, we introduce Argus, an autonomous system that utilizes drones to collect target information incrementally through a two-tier architecture. To tackle the stated challenges, Argus employs a novel geometric model that captures both target shapes and coverage constraints. Recognizing drones as the scarcest resource, Argus aims to minimize the number of drones required to cover a set of targets. We prove this problem is NP-hard, and even hard to approximate, before deriving a best-possible approximation algorithm along with a competitive sampling heuristic which runs up to 100× faster according to large-scale simulations. To test Argus in action, we demonstrate and analyze its performance on a prototype implementation. Finally, we present a number of extensions to accommodate more application requirements and highlight some open problems.
Changes in skeletal muscle histology and metabolism in patients undergoing exercise deconditioning: Effect of propionyl-L-carnitine (1997)

To define the skeletal muscle abnormalities in patients undergoing exercise deconditioning and evaluate the metabolic effect of propionyl-L-carnitine (PLC), muscle biopsies were obtained from 28 patients with effort angina and 31 control subjects. Coronary artery disease patients received either placebo (n = 12), PLC (1.5 g i.v. followed by infusion of 1 mg/kg/min for 30 min, n = 10), or L-carnitine (1 g i.v. followed by infusion of 0.65 mg/kg/min for 30 min, n = 6) for 2 days. Exercise deconditioned patients treated with placebo showed normal muscle content of total carnitine and glycogen, and decrease in percentage of type 1 fibers (P < 0.01) and in the activity of citrate synthase (P < 0.05), succinate dehydrogenase (P < 0.05), and cytochrome oxidase (P < 0.05), as compared to controls. Both PLC and L-carnitine did not modify muscle fiber composition or enzyme activities, but significantly increased muscle levels of total carnitine by 42% and 31%, respectively (P < 0.05). Moreover, PLC significantly increased glycogen muscle content (P < 0.01), while the equimolar dose of L-carnitine did not. This effect, probably due to the anaplerotic activity of the propionic group of PLC, suggests that this drug may be effective in improving energy metabolism of muscles with impaired oxidative capacity.
SCORPIO: A 36-core research chip demonstrating snoopy coherence on a scalable mesh NoC with in-network ordering (2014)

In the many-core era, scalable coherence and on-chip interconnects are crucial for shared memory processors. While snoopy coherence is common in small multicore systems, directory-based coherence is the de facto choice for scalability to many cores, as snoopy relies on ordered interconnects which do not scale. However, directory-based coherence does not scale beyond tens of cores due to excessive directory area overhead or inaccurate sharer tracking. Prior techniques supporting ordering on arbitrary unordered networks are impractical for full multicore chip designs.
