Foucault Sobre Ética Y Subjetividad: 'Cuidado De Sí' Y 'Estética De La Existencia' (2017)

El artículo «Foucault on Ethics and Subjectivity: ‘Care of the Self’ and ‘Aesthetics of Existence’» fue publicado originalmente en <em>Foucault Studies</em>, nº 19, 135-150, junio de 2015. Ha sido traducido para <em>Dorsal</em> por Eugenia Victoria Arria Álvarez y Juan Horacio de Freitas. <strong>Resumen: </strong>Este ensayo considera la estructura del sujeto ético que se encuentra en los últimos trabajos de Foucault sobre ética, y da cuenta de sus dos conceptos éticos fundamentales: “cuidado de sí” y “estética de la existencia”. El “cuidado de sí”, se argumenta, da a Foucault una manera de conceptualizar la ética que no depende de categorías jurídicas, y que no concibe al sujeto ético en el modelo de la sustancia. “El cuidado de sí” conlleva una comprensión del sujeto ético como un proceso que siempre es relacional, especialmente en relación consigo mismo. Valiéndonos de su ensayo “Qué es un Autor”, se argumenta que al sujeto de la “estética de la existencia”, igual que al autor de un texto, se les entiende como totalmente inmanentes al “objeto”, que usualmente es considerado como opuesto y separado. En lugar de proponer una expresión verdadera de una sustancia interior “auténtica”, la “estética de la existencia” de Foucault se orienta más bien a las prácticas de “creatividad”, cuya forma no puede anticiparse. <strong>Abstract</strong>: This paper considers the structure of the ethical subject found in Foucault’s late works on ethics, and gives an account of his two major ethical concepts: “care of the self” and “aesthetics of existence.” The “care of the self,” it is argued, gives Fou-cault a way of conceptualising ethics which does not rely on juridical categories, and which does not conceive the ethical subject on the model of substance. The “care of the self” entails an understanding of the ethical subject as a process which is always in a relation, specifically in a relation to itself. Using his essay “What is an Author,” it is ar-gued that the subject of the “aesthetics of existence,” like the author of a text, is under-stood to be fully immanent to the “object” which it is usually considered to be opposed to and separated from. Rather than aiming at a true expression of an “authentic” inner substance, Foucault’s “aesthetics of existence” leads instead to practices of “creativity,” whose form cannot be given in advance.
Mixed Polarity in Polarization-Induced p–n Junction Nanowire Light-Emitting Diodes (2013)

Polarization-induced nanowire light emitting diodes (PINLEDs) are fabricated by grading the Al composition along the c-direction of AlGaN nanowires grown on Si substrates by plasma-assisted molecular beam epitaxy (PAMBE). Polarization-induced charge develops with a sign that depends on the direction of the Al composition gradient with respect to the [0001] direction. By grading from GaN to AlN then back to GaN, a polarization-induced p-n junction is formed. The orientation of the p-type and n-type sections depends on the material polarity of the nanowire (i.e., Ga-face or N-face). Ga-face material results in an n-type base and a p-type top, while N-face results in the opposite. The present work examines the polarity of catalyst-free nanowires using multiple methods: scanning transmission electron microscopy (STEM), selective etching, conductive atomic force microscopy (C-AFM), and electroluminescence (EL) spectroscopy. Selective etching and STEM measurements taken in annular bright field (ABF) mode demonstrate that the preferred orientation for catalyst-free nanowires grown by PAMBE is N-face, with roughly 10% showing Ga-face orientation. C-AFM and EL spectroscopy allow electrical and optical differentiation of the material polarity in PINLEDs since the forward bias direction depends on the p-n junction orientation and therefore on nanowire polarity. Specifically, C-AFM reveals that the direction of forward bias for individual nanowire LEDs changes with the polarity, as expected, due to reversal of the sign of the polarization-induced charge. Electroluminescence measurements of mixed polarity PINLEDs wired in parallel show ambipolar emission due to the mixture of p-n and n-p oriented PINLEDs. These results show that, if catalyst-free III-nitride nanowires are to be used to form polarization-doped heterostructures, then it is imperative to understand their mixed polarity and to design devices using these nanowires accordingly.
Using Abaqus/Explicit to Link the Manufacturing Process to the Final Part Quality for Continuous Fiber-Reinforced Composite Fabrics (2012)

The manufacture of continuous fiber-reinforced composite parts often involves a design- build-test methodology which can be expensive and time-consuming. A predictive design tool, such as the finite element method, is valuable to assist in understanding the relationship between the composite processing conditions and part quality, thus reducing the dependence on the design- build-test methodology. The ability of the design tool to predict part quality based on manufacturing process parameters is dependent upon the mechanical behavior of the fabric reinforcements, which includes the in-plane shearing and tensile behaviors, bending stiffness and friction between contacting surfaces during the manufacturing process. A hybrid finite element discrete mesoscopic approach is proposed to model the forming of continuous fiber-reinforced composite fabrics. The yarns are modeled by 1-D elements, and the shearing behavior of the fabric is incorporated with 2-D elements. Forming simulations are demonstrated using an automotive part and a wind turbine blade, where feedback can be provided to either change processing parameters or part design to optimize part quality.
Face retrieval using 1st- and 2nd-order PCA mixture model (2003)

This paper deals with face retrieval using the 1st- and 2nd-order PCA mixture model. The well-known eigenface method uses one set of holistic facial features obtained by PCA. However, the single set of eigenfaces is not enough to represent face images with large variations. To overcome this weakness, we propose the method that uses more than one set of eigenfaces obtained from the EM learning in PCA mixture model. 2nd-order eigenface method can be extended to the method using 2nd-order PCA mixture model, also. Simulation results show that the method using 2nd-order PCA mixture model is the best for the face images with illumination variations and the method using 1st-order PCA mixture model is the best for the face images with pose variations in, terms of ANMRR (average of the normalized modified retrieval rank).

Reproducing kernel hierarchical partition of unity, Part I?formulation and theory (1999)

This work is concerned with developing the hierarchical basis for meshless methods. A reproducing kernel hierarchical partition of unity is proposed in the framework of continuous representation as well as its discretized counterpart. To form such hierarchical partition, a class of basic wavelet functions are introduced. Based upon the built-in consistency conditions, the differential consistency conditions for the hierarchical kernel functions are derived. It serves as an indispensable instrument in establishing the interpolation error estimate, which is theoretically proven and numerically validated. For a special interpolant with different combinations of the hierarchical kernels, a synchronized convergence effect may be observed. Being different from the conventional Legendre function based p-type hierarchical basis, the new hierarchical basis is an intrinsic pseudo-spectral basis, which can remain as a partition of unity in a local region, because the discrete wavelet kernels form a ‘partition of nullity’. These newly developed kernels can be used as the multi-scale basis to solve partial differential equations in numerical computation as a p-type refinement. Copyright © 1999 John Wiley & Sons, Ltd.
Structures and Oxygen Affinities of Crystalline Human Hemoglobin C (β6 Glu→Lys) in the R and R2 Quaternary Structures (2011)

Recent crystallographic studies suggested that fully liganded human hemoglobin can adopt multiple quaternary conformations that include the two previously solved relaxed conformations, R and R2, whereas fully unliganded deoxyhemoglobin may adopt only one T (tense) quaternary conformation. An important unanswered question is whether R, R2, and other relaxed quaternary conformations represent different physiological states with different oxygen affinities. Here, we answer this question by showing the oxygen equilibrium curves of single crystals of human hemoglobin in the R and R2 state. In this study, we have used a naturally occurring mutant hemoglobin C (β6 Glu→Lys) to stabilize the R and R2 crystals. Additionally, we have refined the x-ray crystal structure of carbonmonoxyhemoglobin C, in the R and R2 state, to 1.4 and 1.8 Å resolution, respectively, to compare precisely the structures of both types of relaxed states. Despite the large quaternary structural difference between the R and R2 state, both crystals exhibit similar noncooperative oxygen equilibrium curves with a very high affinity for oxygen, comparable with the fourth oxygen equilibrium constant (K(4)) of human hemoglobin in solution. One small difference is that the R2 crystals have an oxygen affinity that is 2-3 times higher than that of the R crystals. These results demonstrate that the functional difference between the two typical relaxed quaternary conformations is small and physiologically less important, indicating that these relaxed conformations simply reflect a structural polymorphism of a high affinity relaxed state.

Species differences of bombesin analog interactions with GRP-R define the choice of animal models in the development of GRP-R-targeting drugs. (2005)

Considerable differences between rat or mouse and human GRP-R-expressing tissues were found for the in vitro and in vivo characteristics of 2 radiolabeled bombesin analogs. This finding may have a significant impact in the selection of experimental tools in the development of bombesin analogs for GRP-R-targeting applications in humans.
Extracting formal domain models from exsisting code for generative reuse (1997)

The existence of a domain model that formally describes the meaning of a piece of software can be helpful for re-use. We illustrate an approach, where by reengineering a formal domain model out of an existing system, one can generalize the existing system to an application generator: we map a domain model for program representations into the front end of a compiler, using the Genii system, and use this in Genoa , an application generator for language tools. This approach shows promise in other domains, as well.
A pressure indicating ring for patients with hand pressure sense loss (1988)

Patients with loss of the sense of pressure exerted by the hand tend to hold objects with excessive pressure, leading to compression of blood vessels. This, over a period, leads to tissue necrosis due to reduction in blood circulation. To give an indication of excessive gripping pressure so that these patients can prevent hands damage, a double-layered ring has been designed when it is worn by the patient, and indication of excessive pressure is obtained in the form of change in color of a layer of liquid crystal mixture sandwiched between the two layers of the ring.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Adenovirus F protein as a delivery vehicle for botulinum B (2010)

These results demonstrate that Hcbetatre-based immunogens are highly immunogenic, especially when genetically fused to Ad2F, and Ad2F can be exploited as a vaccine delivery platform to the mucosa.
Observation of Josephson coupling through an interlayer of antiferromagnetically ordered chromium (2009)

The supercurrent transport in metallic Josephson tunnel junctions with an additional interlayer made up by chromium, being an itinerant antiferromagnet, was studied. Uniform Josephson coupling was observed as a function of the magnetic field. The supercurrent shows a weak dependence on the interlayer thickness for thin chromium layers and decays exponentially for thicker films. The diffusion constant and the coherence length in the antiferromagnet were estimated. The antiferromagnetic state of the barrier was indirectly verified using reference samples. Our results are compared to macroscopic and microscopic models.
In search of pathologic correlates for hearing loss and vertigo in Paget's disease. A clinical and histopathologic study of 26 temporal bones. (1990)

Mixed sensorineural and conductive hearing loss is a common clinical manifestation of Paget's disease of the temporal bone, and while there are numerous clinical and pathologic reports on the condition, none have identified a consistent pathologic explanation for the hearing loss. We performed histologic studies on 26 temporal bones exhibiting Paget's disease from 16 persons, of whom 7 had audiometric testing performed. Contrary to common opinion, the conductive hearing loss is not caused by ossicular fixation; in fact, no cause could be found in the seven ears with documented conductive hearing losses. While the sensorineural hearing losses were greater than normal for age, we could not identify cochlear disorders that could be attributed to Paget's disease. It is concluded that the hearing losses in Paget's disease are caused by changes in bone density, mass, and form that serve to dampen the finely tuned motion mechanics of the middle and inner ears.
Cyclosporine in acute ischemic stroke (2015)

This study provides Class I evidence that in patients with an acute anterior-circulation stroke, thrombolysis plus IV cyclosporine does not significantly decrease 30-day MRI infarct volume compared with thrombolysis alone.
Effective inhibition of Rta expression and lytic replication of Kaposi's sarcoma-associated herpesvirus by human RNase P (2004)

Ribonuclease P (RNase P) complexed with external guide sequence (EGS) represents a nucleic acid-based gene interference approach to knock-down gene expression. Unlike other strategies, such as antisense oligonucleotides, ribozymes, and RNA interference, the RNase P-based technology is unique because a custom-designed EGS molecule can bind to any complementary mRNA sequence and recruit intracellular RNase P for specific degradation of the target mRNA. In this study, we demonstrate that the RNase P-based strategy is effective in blocking gene expression and growth of Kaposi's sarcoma (KS)-associated herpesvirus (KSHV), the causative agent of the leading AIDS-associated neoplasms, such as KS and primary-effusion lymphoma. We constructed 2'-O-methyl-modified EGS molecules that target the mRNA encoding KSHV immediate-early transcription activator Rta, and we administered them directly to human primary-effusion lymphoma cells infected with KSHV. A reduction of 90% in Rta expression and a reduction of approximately 150-fold in viral growth were observed in cells treated with a functional EGS. In contrast, a reduction of <10% in the Rta expression and viral growth was found in cells that were either not treated with an EGS or that were treated with a disabled EGS containing mutations that preclude recognition by RNase P. Our study provides direct evidence that EGSs are highly effective in inhibiting KSHV gene expression and growth. Exogenous administration of chemically modified EGSs in inducing RNase P-mediated cleavage represents an approach for inhibiting specific gene expression and for treating human diseases, including KSHV-associated tumors.
Effects of annealing and temperature on acoustic dissipation in a micromechanical silicon oscillator (2005)

The temperature dependence (15–320K) of the acoustic dissipation was studied for some lower vibrational modes of a suspended silicon plate 1.5μm thick. Our oscillator was exposed to the laboratory environment prior to measurement, laser annealed while in a cryogenic vacuum, and remeasured. We find a dissipation peak at 160K, similar to results by others, and a second dissipation peak near 30K. Annealing reduced the dissipation at 160K by as much as a factor of 10, and gave quality factors as high as 1.4×106 at 470kHz and our lowest temperature. Our data support the idea that the 160K peak is related to adsorbates, and show this mechanism is important at room temperature. Post-anneal room-temperature dissipation appears to be limited by thermoelastic loss for certain modes.
Renewable-Resource Thermoplastic Elastomers Based on Polylactide and Polymenthide (2007)

An alpha,omega-functionalized polymenthide was synthesized by the ring-opening polymerization of menthide in the presence of diethylene glycol with diethyl zinc as the catalyst. Termination with water afforded the dihydroxy polymenthide. The reaction of this telechelic polymer with triethylaluminum formed the corresponding aluminum alkoxide macroinitiator that was used for the controlled polymerization of lactide to yield biorenewable polylactide-b-polymenthide-b-polylactide triblock copolymers. The molecular weight and chemical composition were easily adjusted by the monomer-to-initiator ratios. Microphase separation in these triblock copolymers was confirmed by small-angle X-ray scattering and differential scanning calorimetry. A representative triblock was prepared with a hexagonally packed cylindrical morphology as determined by small-angle X-ray scattering, and tensile testing was employed to assess the mechanical behavior. On the basis of the ultimate elongations and elastic recovery, these triblock copolymers behaved as thermoplastic elastomers.
Optical matrix–vector multiplication through four-wave mixing in photorefractive media (1987)

We propose and describe a new method of optical matrix-vector multiplication by using four-wave mixing in photorefractive media. Using a BaTiO(3) crystal, we have demonstrated such a parallel multiplication. The results are presented and discussed.
Development of Children's Knowledge of Story Structure and Content (1985)

AbstractThis study investigated the development of intermediate-grade children's knowledge of both structural features and content of stories from a longitudinal perspective. At the beginning of both the fourth and sixth grades, 30 subjects told two stories and recalled two scrambled stories.Knowledge of structural features was determined mainly by stuctural complexity in story productions and by the degree to which scrambled stories were restructured into the canonical versions. Knowledge of story content was examined in the story productions by determining the amount and nature of conflict, characters' response to conflict, and conflict resolution, and by analyses of actions occurring in the stories.Two primary conclusions were drawn. First, children did acquire over the intermediate grades greater knowledge about structural complexity in stories. Second, there were few indications of growth in knowledge of content, either when conflict, response, and resolution were examined or when story actions were explored.
The preference for a 3' homologous end is intrinsic to RecA-promoted strand exchange. (1990)

The recA protein (RecA) promotes DNA pairing and strand exchange optimally in the presence of single-stranded binding protein (SSB). Under these conditions, 3' homologous ends are essential for stable joint molecule formation between linear single-stranded DNA (ssDNA) and supercoiled DNA (i.e. 3' ends are 50-60 times more reactive than 5' ends). Linear ssDNAs with homology at the 5' end do not participate in pairing. In the absence of SSB, the strand exchange reaction is less efficient; however, linear ssDNAs with 3' end homology are still 5- to 10-fold more reactive than those with 5' end homology. The preference for a 3' homologous end in the absence of SSB suggests that this is an intrinsic property of RecA-promoted strand exchange. The preferential reactivity of 3' homologous ends is likely to be a consequence of the polarity of polymerization of RecA on ssDNA. Specifically, since RecA polymerizes in the 5'----3' direction, 3' ends are more likely to be coated with RecA and, hence, will be more reactive than 5' ends.
Neuroanatomical Substrates of Functional Recovery After Experimental Spinal Cord Injury: Implications of Basic Science Research for Human Spinal Cord Injury (2000)

Human spinal cord injury (SCI) is a devastating condition that results in persistent motor deficits. Considerable basic and clinical research is directed at attenuating these deficits. Many basic scientists use animal models of SCI to (1) characterize lesion development, (2) determine the role of spared axons in recovery, and (3) develop therapeutic interventions based on these findings. In this article, current research is reviewed that indicates: (1) most individuals with SCI will have some sparing of white matter at the lesion epicenter even when the lesion appears clinically complete, (2) even minimal tissue sparing has a profound impact on segmental systems and recovery of function, and (3) facilitatory intervention such as weight bearing and locomotor training after SCI may be more effective than compensatory strategies at inducing neuroplasticity and motor recovery. Body weight supported treadmill step training is discussed as an example of new facilitatory interventions based on basic science research using animal models.
A Monolithic High-Performance Buck Converter With Enhanced Current-Mode Control and Advanced Protection Circuits (2015)

A monolithic high-performance step-down dc-dc converter for high power point-of-load application is presented in this paper. A novel adaptive quadratic slope compensation method and an adaptive antijittering ramp scheme are proposed to enhance the performance of widely used peak current-mode control. A fast overcurrent detection method together with a robust driver control logic design has been introduced to increase the circuits' reliability. The dc-dc converter has been designed and fabricated in a 0.35-μm Bipolar-CMOS-DMOS process with an area of 6 mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> . With the proposed enhanced current-mode control, our design allows more flexibility on inductor selection, switching frequency, and output voltage. Experimental results have shown great adaptability for various application configurations. This converter has also shown fast line step response and low PWM jittering. It can operate at beyond 9-A peak current and up to 1.4-MHz switching frequency with supply voltage from 2.35 to 6 V. Measured peak efficiency is 96.6% and over 92% efficiency for 6-A output current is realized as well.
An amorphous silicon photodetector for picosecond pulses (1980)

A new photoconductive detector utilizing an amorphous silicon film grown by CVD is demonstrated to have a response time of 40 ps. An estimate of the carrier mobility suggests a mechanism involving the rapid relaxation of photoexcited carriers from relatively mobile extended states to immobile localized states.
