El dispositivo artístico. Un acercamiento crítico y genealógico a las condiciones aporéticas de la producción artística latinoamericana: el caso de la Vanguardia argentina de los años sesenta (2013)

En el presente trabajo se ofrece un acercamiento reflexivo en torno a cómo el arte, en tanto producto de la cultura liberal, es ante todo un dispositivo disciplinario que ha cooptado para sí al acontecer estético y ha logrado posicionar la idea de su supuesta universalidad y autonomía. Por tanto, se propone realizar una reflexión crítica de cómo el dispositivo artístico, fundamentado en las ideas de autonomía y universalidad, ha coadyuvado para hacer del acontecer estético una especie de propiedad privada que, por un lado, sólo el artista es capaz ontológica y jurídicamente de manifestar y, por el otro, sólo el sujeto sensible, aquel que ha naturalizado la sensibilidad propia de la cultura burguesa liberal, es capaz de disfrutar para reconocer su libertad y su derecho a poseer y dominar.Es decir, el arte no sólo cumple una función ideológica por su condición de mercancía, sino que además condiciona históricamente lo que puede ser reconocido o no como estético; y a su vez, en ese reconocimiento, propone los límites, asegurados desde la misma cultura burguesa, para determinar cuáles fenómenos estéticos son dignos de mayor valoración y procuración en la vida social. Política sobre la estética que asegura la preeminencia de lo estético a aquellos sujetos que, por “genio” o por “ingenio”, tienen un supuesto derecho ontológico a la cultura.No sólo se busca reflexionar en torno a las condiciones aporéticas propias de la producción artística en tanto mercancía de la cultura liberal, sino que dicha reflexión se ubica históricamente en uno de los ejemplos paradigmáticos de la producción artístico-política latinoamericana de la segunda mitad del siglo XX: la Vanguardia argentina de los años sesenta. La intención es dar cuenta del modo en que dicho dispositivo artístico forma y conforma consecuencias materiales contradictorias, incluso en los proyectos artísticos más contestatarios.
Preparation of visible-light-excited luminescence enhancement solutions for time-resolved luminescence detection of europium biolabel (2012)

Dissociation enhanced lanthanide fluoroimmunoassay (DELFIA) technique based on EDTA-Eu(3+) derivative biolabels is the most widely used time-resolved luminescence bioassay technique for clinical diagnosis, but its major drawback is that the conventional luminescence enhancement solution of EDTA-Eu(3+) requires UV excitation (<360 nm). In this work, three new visible-light-excited luminescence enhancement solutions are developed and their luminescence response behaviors to EDTA-Eu(3+) are systematically investigated. The new solutions were prepared by co-dissolving a newly synthesized tetradentate β-diketone, 1,2-bis[8'-(1'',1'',1'',2'',2'',3'',3''-heptafluoro-4'',6''-hexanedion-6''-yl)-naphth-2'-yl]-benzene (BHHNB), and one of three derivatives of triazine, 2-(N,N-diethylanilin-4-yl)-4,6-bis(3,5-dimethylpyrazol-1-yl)-1,3,5-triazine (DPBT), 2-(N,N-diethylanilin-4-yl)-4,6-bis(3-methylpyrazol-1-yl)-1,3,5-triazine (MPBT) or 2-(N,N-diethylanilin-4-yl)-4,6-bis(pyrazol-1-yl)-1,3,5-triazine (BPT), in a weakly acidic aqueous buffer at pH 3.2 containing 0.1% Triton X-100. These solutions showed sensitive and rapid luminescence responses to non-luminescent EDTA-Eu(3+) by the formation of the ternary Eu(3+) complexes, BHHNB-Eu(3+)-DPBT, BHHNB-Eu(3+)-MPBT and BHHNB-Eu(3+)-BPT. These complexes have long luminescence lifetimes (>500 μs) and a wide excitation wavelength range from UV to visible light with the excitation peaks at 390, 400 and 420 nm, respectively, which enabled the solutions to be used as visible-light-excited luminescence enhancement solutions for the highly sensitive time-resolved luminescence detection of EDTA-Eu(3+).
Cadmium removal by a new strain of Pseudomonas aeruginosa in aerobic culture (1997)

A fluorescent pseudomonad (strain CW-96-1) isolated from a deep-sea vent sample grew at 30 degrees C under aerobic conditions in an artificial seawater medium and tolerated cadmium concentrations up to 5 mM. After 140 h, strain CW-96-1 removed > 99% of the cadmium from solution. Energy dispersive microanalysis revealed that the cadmium was removed by precipitation on the cell wall; sulfide production was confirmed by growth on Kligler's agar. Based on 16S ribosomal DNA sequencing and fatty acid analysis, the microorganism is closely related to Pseudomonas aeruginosa.
The senescence‐accelerated mouse: a model for the investigation of age‐related oxidative stress and diastolic dysfunction (2008)

Diastolic dysfunction (DD) is characterized by impaired active relaxation, increased stiffness, and often progresses to diastolic heart failure. Although DD has been associated with aging and oxidative stress in humans, mechanisms of DD have proven difficult to study due to lack of relevant animal models. We have used the senescence‐accelerated mouse model (SAM) to investigate DD. This model mimics many geriatric disorders observed in humans and consists of two strains, senescence‐prone (SAMP8) and senescence‐resistant controls (SAMR1). Oxidative stress was measured in aortas using electron spin resonance. Pulsed‐wave Doppler echocardiography was used to assess blood flow velocity (E/A), tissue‐Doppler imaging was used to assess mitral annulus velocity (E’/A’), and color M‐mode imaging was used to measure the propagation inflow velocity (V p ). SAMP8 mice had a two‐fold increase in vascular superoxide compared to controls (p<0.05; n=3). The E/A ratio was reduced from 4.2 ± 0.1 cm/s in SAMR1 to 1.9 ± 0.3 cm/s in SAMP8 mice. The E’/A’ ratio was similarly reduced from 1.6 ± 0.1 to 0.6 ± 0.1 in SAMR1 vs. SAMP8 mice, respectively. Finally, V p was decreased from 42.7 ± 2.4 cm/s in SAMR1 to 24.7 ± 2.0 cm/s in SAMP8 mice (p<0.05; n=3). These data suggest that aging is associated with DD and oxidative stress in this model; therefore, it may be useful in elucidating the mechanisms behind DD.
Microsoft TerraServer: A Spatial Data Warehouse (1999)

The TerraServer stores aerial, satellite, and topographic images of the earth in a SQL database available via the Internet. It is the world's largest online atlas, combining five terabytes of image data from the United States Geological Survey (USGS) and SPIN-2. This report describes the system-redesign based on our experience over the last year. It also reports usage and operations results over the last year -- over 2 billion web hits and over 20 Terabytes of imagry served over the Internet. Internet browsers provide intuitive spatial and text interfaces to the data. Users need no special hardware, software, or knowledge to locate and browse imagery. This paper describes how terabytes of "Internet unfriendly" geo-spatial images were scrubbed and edited into hundreds of millions of "Internet friendly" image tiles and loaded into a SQL data warehouse. Microsoft TerraServer demonstrates that general-purpose relational database technology can manage large scale image repositories, and shows that web browsers can be a good geospatial image presentation system.
Cystatin C deficiency suppresses tumor growth in a breast cancer model through decreased proliferation of tumor cells (2017)

Cysteine cathepsins are proteases that, in addition to their important physiological functions, have been associated with multiple pathologies, including cancer. Cystatin C (CstC) is a major endogenous inhibitor that regulates the extracellular activity of cysteine cathepsins. We investigated the role of cystatin C in mammary cancer using CstC knockout mice and a mouse model of breast cancer induced by expression of the polyoma middle T oncoprotein (PyMT) in the mammary epithelium. We showed that the ablation of CstC reduced the rate of mammary tumor growth. Notably, a decrease in the proliferation of CstC knockout PyMT tumor cells was demonstrated <i>ex vivo</i> and <i>in vitro</i>, indicating a role for this protease inhibitor in signaling pathways that control cell proliferation. An increase in phosphorylated p-38 was observed in CstC knockout tumors, suggesting a novel function for cystatin C in cancer development, independent of the TGF-β pathway. Moreover, proteomic analysis of the CstC wild-type and knockout PyMT primary cell secretomes revealed a decrease in the levels of 14-3-3 proteins in the secretome of knock-out cells, suggesting a novel link between cysteine cathepsins, cystatin C and 14-3-3 proteins in tumorigenesis, calling for further investigations.
New multiple matched filter: design and experimental realization (1986)

A method of making a multiple matched filter which allows the recognition of different characters in successive planes in simple conditions is proposed. The generation of the filter is based on recording on the same plate the Fourier transforms of the different patterns to be recognized, each of which is affected by different spherical phase factors because the patterns have been placed at different distances from the lens. This is proved by means of experiments with a triple filter which allows satisfactory recognition of three characters.
The use of initial fees and royalties in business‐format franchising (1993)

Abstract This paper provides an explanation of franchising's fee structure, drawing on principal agency and labor economics theory. The predictive framework includes constructs such as channel control, franchisor services, franchisee risk and the franchisor's capital constraints. The empirical investigation of a representative sample of franchise chains indicates that channel control is the major factor influencing the payment design. The results are used to test managerial implications about the use of an optimal fee structure in the growth of chains.
Switching loss characteristics of sequences involving active state division in space vector based PWM (2004)

This paper analyzes the switching loss characteristics of sequences involving division of active state duration in space vector based PWM. This analysis, together with the THD performance of the different sequences, reported recently, is used to design new hybrid PWM techniques for induction motor drives, which result in simultaneous reduction in both THD as well as inverter switching losses. Experimental results are presented to demonstrate the feasibility and advantages of the proposed PWM techniques.
Video Coding with Spatio-Temporal Texture Synthesis (2007)

This paper presents a video coding scheme in which some texture regions are selectively removed at the encoder and recovered by synthesis at the decoder. We present region removal utilizing conventional block-based motion information rather than global motion field. Removed regions including their motion information are not coded at the encoder. We propose spatio-temporal patch-searching in texture synthesis at the decoder to recover the removed regions. Our approach is not content based and is flexible and generic to be implemented. The scheme has been integrated into H.264/AVC and achieves up to 38.8% bitrate saving at similar visual quality levels compared with H.264/AVC.
Time-resolved Forster energy transfer in polymer blends (2003)

Summary form only given. A promising way to lower the lasing thresholds is to use energy transfer in host-guest systems to red-shift the emission sufficiently far from the host absorption that self-absorption by the host becomes negligible. The dipole-dipole interaction leads to efficient, long-range energy transfer from an absorbing host chromophore to an emitting guest chromophore. We are using poly (2,3-diphenyl-5-hexyl-1,4-phenylenevinylene) (DP6-PPV) and poly[2-(meta-2'-ethylhexoxyphenyl)-1,4-phenylenevinylene] (m-EHOP-PPV) as host polymers, and poly(2,5-bis (2'-ethylhexoxy)-1,4-phenylenevinylene) (BEH-PPV) and poly(2,5-bis(cholestanoxy)-1,4-phenylenevinylene) (BCHA-PPV) as guest polymers. The dashed lines show the optical density while the dotted lines show the photoluminescence (PL) spectra. Positive changes in the solid lines indicate stimulated emission (SE), while negative changes indicate photoinduced absorption (PA). By blending, the emissive properties are improved substantially, the absorption of the blend resembles the absorption of the host polymer, while the PL resembles the emission from the guest (slightly red-shifted), indicating complete energy transfer.
Programmable synthesis using a new "Speech microprocessor" (2005)

In the past, real-time synthesis has been achieved using either relatively expensive special hardware or custom integrated circuitry which implements a single synthesis algorithm. In order to fill a need for low cost, high quality synthesis with algorithm flexibility, two NMOS LSI devices which implement a programmable speech microprocessor have been developed. By orienting the architecture toward common features of several classes of digital vocal tract models, synthesis computations involving a large number of multiplies, adds, and other operations can be performed efficiently. For example, the processor can implement a complex cascade/parallel formant synthesizer or a lattice filter with up to fourteen poles. The LSI chip set will become commerically available in mid-1980.
Gastric Inhibitory Polypeptide, Cholecystokinin, and Secretin Effects on Insulin and Glucagon Secretion by Islet Cultures (1979)

SummaryUsing an in vitro islet cell culture assay system, GIP and CCK-OP appear to be about equally potent insulinotropic agents. Secretin has only a very slight stimulatory effect on insulin release, and only at a very high peptide concentration. Furthermore, GIP plus CCK-OP and GIP plus secretin appear to have synergistic insulinogenic actions. If supraphysiologic GIP concentrations are tested, glucose is not necessary at an insulin stimulatory concentration for GIP to stimulate insulin secretion.Glucagon release is enhanced only by GIP at physiologic peptide concentrations. Both secretin and CCK-OP have only very slight glucagonotropic actions even at high concentrations.
In-chip overlay measurement by existing bright-field imaging optical tools (2005)

We have developed a target design for overlay measurement which is small enough (3x3μm) that it could be positioned within the active area of integrated circuit devices. These targets have been measured using an unmodified overlay tool. The targets are too small for the image to be fully resolved using visible wavelengths, and so measurement using the normal methods based on determining the relative positions of features in the image does not produce acceptable levels of measurement uncertainty. Instead, we show that the symmetry of the image can be used to determine the overlay error. We report initial results which show measurement uncertainty using this technique approaching the levels needed for overlay control at design rules under 100nm. These results are limited by the process used to create our test structures, and even better results may be possible with state-of-the-art lithography and processing techniques.
The Conversion of Catechol and Protocatechuate to β-Ketoadipate by Pseudomonas putida (1966)

Abstract Study of the regulation of the syntheses of enzymes of the catechol and protocatechuate pathways in Pseudomonas putida has shown that two groups of enzymes are subject to coordinate control. cis,cis-Muconate-lactonizing enzyme and muconolactone isomerase, which are uniquely associated with the catechol pathway, constitute the first coordinate block of enzymes. The synthesis of these enzymes, as well as that of catechol oxygenase (which is regulated independently), seems to be induced by cis,cis-muconate. The second coordinate block of enzymes comprises β-carboxy-cis,cis-muconate-lactonizing enzyme and γ-carboxymuconolactone decarboxylase, which are uniquely associated with the protocatechuate pathway, and β-ketoadipate enol-lactone hydrolase, which is functional in both the protocatechuate and the catechol pathways. This group of enzymes seems to be induced by β-ketoadipate or β-ketoadipyl coenzyme A. Moraxella lwoffii, which degrades protocatechuate and catechol through identical step-reactions, regulates the synthesis of the enzymes mediating these conversions by a different mechanism.
In Situ Observations of a High-Pressure Phase of H <sub>2</sub> O Ice (1998)

A previously unknown solid phase of H2O has been identified by its peculiar growth patterns, distinct pressure-temperature melting relations, and vibrational Raman spectra. Morphologies of ice crystals and their pressure-temperature melting relations were directly observed in a hydrothermal diamond-anvil cell for H2O bulk densities between 1203 and 1257 kilograms per cubic meter at temperatures between -10 degrees and 50 degreesC. Under these conditions, four different ice forms were observed to melt: two stable phases, ice V and ice VI, and two metastable phases, ice IV and the new ice phase. The Raman spectra and crystal morphology are consistent with a disordered anisotropic structure with some similarities to ice VI.
Effect of ischemic preconditioning on interstitial purine metabolite and lactate accumulation during myocardial ischemia. (1994)

The purpose of this study was to determine the effect of ischemic preconditioning on the changes in interstitial fluid (ISF) purine metabolites and lactate during prolonged regional myocardial ischemia. The study consisted of two groups of anesthetized dogs: a control group (n = 13) that was exposed to 60 minutes of regional myocardial ischemia and a preconditioned group (n = 10). In the preconditioned group, regional myocardial ischemia was induced for two 5-minute episodes, each followed by 10 minutes of reperfusion. These preconditioning episodes were followed by 60 minutes of sustained regional ischemia. Cardiac ISF was sampled by microdialysis probes implanted in the left ventricular myocardium; dialysate levels served as indices of ISF concentrations. In the preconditioned group, dialysate concentrations of adenosine, inosine, hypoxanthine, total purines, and lactate increased during each of the 5-minute ischemia episodes, with further increases occurring during the first 5 minutes of reperfusion. However, the increases in dialysate purine metabolites during the first period of ischemia/reperfusion were greater than those that occurred during the second ischemia/reperfusion. In addition, preconditioning reduced the rate of ISF purine metabolite and lactate accumulation during the prolonged ischemia when compared with nonpreconditioned animals. These data suggest that preconditioning reduces the energy imbalance that occurs during subsequent myocardial ischemia and thereby diminishes the rate of net adenine nucleotide degradation and cellular production and release of purine metabolites and lactate. In addition, the increase in ISF adenosine seen during the preconditioning episode is consistent with the notion that preconditioning-induced cardioprotection is mediated in part by the action of adenosine at extracellular A1 adenosine receptors.
Integration of detectors with GaInAsP/InP carrier depletion optical switches (1990)

An optical switch made of carrier depletion directional couplers based on GaInAsP/InP double-heterostructure waveguides with integrated detectors was realised. The device was fabricated using a two step Cl-VPE epitaxy and shows good performances both in terms of switching (phase modulation efficiency ñ 12°/V/mm) and detecting properties (detector leakage current ñ 1 nA at −5 V).
Distributed computing research issues in grid computing (2002)

Ensembles of distributed, heterogeneous resources, or Computational Grids, have emerged as popular platforms for deploying large-scale and resource-intensive applications. Large collaborative efforts are currently underway to provide the necessary software infrastructure. Grid computing raises challenging issues in many areas of computer science, and especially in the area of distributed computing, as Computational Grids cover increasingly large networks and span many organizations. In this paper we briefly motivate Grid computing and introduce its basic concepts. We then highlight a number of distributed computing research questions, and discuss both the relevance and the short-comings of previous research results when applied to Grid computing. We choose to focus on issues concerning the dissemination and retrieval of information and data on Computational Grid platforms. We feel that these issues are particularly critical at this time, and as we can point to preliminary ideas, work, and results in the Grid community and the distributed computing community. This paper is of interest to distributing computing researchers because Grid computing provides new challenges that need to be addressed, as well as actual platforms for experimentation and research.
Alternansucrase acceptor products (2008)

The regioselectivity of alternansucrase (EC 2.4.1.140) differs from dextransucrase (EC 2.4.1.5) in ways that can be useful for the synthesis of novel oligosaccharide structures. For example, it has been recently shown that the major oligosaccharides produced when maltose is the acceptor include one trisaccharide structure, two tetrasaccharides, one pentasaccharide, two hexasaccharides, one heptasaccharide, and at least two octasaccharides, containing no adjacent α-(1→3) linkages and no more than two consecutive α-(1→6) linkages. This may shed some light on how the enzyme works to produce the alternating structure. Another characteristic of alternansucrase that distinguishes it from dextransucrase is its greater ability to use leucrose as an acceptor. Leucrose, produced by glucosyl transfer to fructose released from the initial sucrose substrate, represents a very poor substrate for Leuconostoc mesenteroides NRRL B-512F dextransucrase. Alternansucrase, however, continues to transfer glucosyl units to leucrose, resulting in some unusual glucosyl-fructose oligosaccharides.

The measurement of tiny dew droplets at the initial deposition stage and dew point using a phase-shift interference microscope (2003)

The shape of a dew droplet deposited on the mirror surface of a copper plate was measured accurately using an interference microscope that employed a phase-shift technique. The microscope was constructed by adding a piezoelectric transducer to an interference microscope. A simple method that uses a conventional speaker horn and an optical fibre cable was used to depress any speckle noise. The shape of a dew droplet deposited at dew point on the plate surface with average roughness of 0.1 µm was measured with an accuracy of ± 3 nm. The mass of a tiny dew droplet could be determined from the volume of its shape and was of the order of 10−9 g. The total mass of a dew droplet deposited per unit area and the deposition velocity under a gentle wind were also obtained in a similar way. The total mass was of the order of 10−5 g cm−2 at the beginning of deposition and the deposition velocity ranged from 1 × 10−5 to 6 × 10−5 g cm−2 min−1 at room temperature.
