"¿Por qué los viejos? Reflexiones desde una Etnografía de la Vejez" (2008)

Esta comunicación tiene por objetivo dar cuenta, desde una perspectiva etnográfica, del modo en que distintos grupos humanos o diversos sectores de una sociedad construyen diferentes imágenes, representaciones e ideas respecto de los viejos. En particular, nos proponemos reflexionar acerca de tres tópicos: la diversidad cultural de los conceptos de viejo y vejez; la interrelación entre la construcción simbólica de estas nociones y las particulares experiencias del envejecer, y algunas reflexiones del quehacer vinculado a una Etnografía de la vejez. Un acercamiento etnográfico a las vejeces debe conjugar las conceptualizaciones biológica y sociocultural de la edad. Conjuntamente, el análisis del tema puede enriquecerse con un abordaje articulado en dos dimensiones: el modo en que culturalmente se caracteriza el colectivo viejos en cada sociedad o grupo social y la manera en que los sujetos experimentan cambios psicofísicos y sociales derivados de esta etapa de la vida. Por último, el trabajo con envejecientes requiere incorporar una observación sobre la perspectiva del investigador. En este sentido, concluiremos que el tema de la vejez nos remite desde las sociedades tradicionales al escenario de nuestra propia sociedad, en la búsqueda de respuestas más adecuadas a lo que se plantea como problemáticas del envejecimiento.
On-Chip ESD Protection Design With Substrate-Triggered Technique for Mixed-Voltage I/O Circuits in Subquarter-Micrometer CMOS Process (2004)

A new electrostatic discharge (ESD) protection design, by using the substrate-triggered stacked-nMOS device, is proposed to protect the mixed-voltage I/O circuits of CMOS ICs. The substrate-triggered technique is applied to lower the trigger voltage of the stacked-nMOS device to ensure effective ESD protection for the mixed-voltage I/O circuits. The proposed ESD protection circuit with the substrate-triggered technique is fully compatible to general CMOS process without causing the gate-oxide reliability problem. Without using the thick gate oxide, the new proposed design has been fabricated and verified for 2.5/3.3-V tolerant mixed-voltage I/O circuit in a 0.25-/spl mu/m salicided CMOS process. The experimental results have confirmed that the human-body-model ESD level of the mixed-voltage I/O buffers can be successfully improved from the original 3.4 to 5.6 kV by using this new proposed ESD protection circuit.
The Sensor Collaboration Structure of Industrial 4.0 (2016)

As information and technology grow up globally, the business should look for the optimal productivity efficiency and add smart management to maintain the company’s interests and value. In order to achieve the smart productivity, vast businesses pay lots of attention to invest in industrial 4.0 and change their business model. In this research, the sensor collaboration structure will be proposed and established to connect the information base and thing base. Human can make decisions and communicate between the physical domain and the cyber domain. In the physical domain, the sensors can gather the data from the machine, the production line, the factory and the product. By sensor collaboration, the signals and information can transfer quickly and simultaneously in the cyber domain. Through the networking between information base and thing base, decision makers can easily predict, judge and handle the tasks. As a result, information base, thing base and decision makers can become a triangle system to achieve the vertical integration and level contact.
Cost-effective printing of 3D objects with skin-frame structures (2013)

3D printers have become popular in recent years and enable fabrication of custom objects for home users. However, the cost of the material used in printing remains high. In this paper, we present an automatic solution to design a skin-frame structure for the purpose of reducing the material cost in printing a given 3D object. The frame structure is designed by an optimization scheme which significantly reduces material volume and is guaranteed to be physically stable, geometrically approximate, and printable. Furthermore, the number of struts is minimized by solving an l 0 sparsity optimization. We formulate it as a multi-objective programming problem and an iterative extension of the preemptive algorithm is developed to find a compromise solution. We demonstrate the applicability and practicability of our solution by printing various objects using both powder-type and extrusion-type 3D printers. Our method is shown to be more cost-effective than previous works.
Interleukin-23/Th17 pathways and inflammatory bowel disease (2009)

The IL-23/Th17 pathway has recently been identified to play a critical role in a number of chronic inflammatory diseases including inflammatory bowel disease (IBD). The identification in IBD patients of associations in IL23R and regions that include other genes in the IL-23/Th17 pathway has highlighted the importance of proper IL-23/Th17 pathway regulation in intestinal immune homeostasis. IL-23 plays a role in CD4+ Th17 lineage cells, characterized by IL-17 secretion and the expression of the transcription factor retinoic acid-related orphan receptor (ROR)gamma tau, and in other immune and nonimmune cells. The balance between effector T cell subsets, such as Th17 cells, and CD4+ T regulatory subsets is finely regulated; dysregulation of this balance can lead to inflammation and autoimmunity. As such, the IL-23/Th17 pathway contributes to immune responses that play a role in defenses to microbial infection, as well as in the intestinal inflammation observed in both animal models of colitis and human IBD.
Application of wind speed forecasting to the integration of wind energy into a large scale power system (1994)

The use of numerical weather prediction (NWP) model as used by national meteorological agencies is assessed in conjunction with a physical flow model and a statistical model as a means of predicting wind power that could be generated by a large number of wind turbines spread throughout the UK. Economic benefits have been demonstrated, and are evaluated in the form of fossil fuel savings using a numerical simulation model which emulates the power plant scheduling of the England and Wales National Grid. The results highlight the importance of effective planning of on-line reserve capacity to cover sudden deficits in wind power generation.
Thermodynamic Study of Protic Ionic Liquids (2017)

The aim of this thesis was to investigate phase equilibrium and physical properties of a distillable ionic liquid 1,5-diazabicyclo[4.3.0]non-5-enium acetate ([DBNH][OAc]) and a switchable ionic liquid carbon dioxide (CO2) + 1,8-diazabicyclo-[5.4.0]-undec-7-ene (DBU) + glycerol, and their mixtures with water. In addition, the properties of the precursor amidines (DBU and DBN) and their mixtures with water were investigated.
In the physical property study, vapor pressures, densities and several enthalpies (formation, reaction, vaporization, solution) of DBN, DBU and [DBNH][OAc] were determined. The vapor pressure and density measurements were conducted with the distillation column and the oscillating U-tube density meter, respectively. The results were modeled with empirical correlations. [DBNH][OAc] was found to decompose into pure DBN and a stable 5:3 HOAc:DBN complex during the evaporation. Therefore, vapor pressures of the decomposition products were measured from the [DBNH][OAc] samples with the distillation column instead of [DBNH][OAc]. The decomposition of [DBNH][OAc] was observed with several common vapor pressure or vaporization enthalpy measurement methods. The formation and reaction enthalpies of DBN and [DBNH][OAc] were determined with a combination of calorimetric and computational methods. The vaporization enthalpies of DBN and DBU were derived from the vapor pressure correlations. On the other hand, the vaporization enthalpy of [DBNH][OAc] was derived from its gas and liquid phase enthalpies of formation due to its decomposition into DBN and the 5:3 HOAc:DBN complex during the evaporation.
The phase equilibrium study consisted of the measurements and modeling vapor-liquid (VLE) and gas-liquid (GLE) equilibrium. The VLE and GLE measurements were conducted by two variations of the static total method. The GLE was studied for CO2 + glycerol, CO2 + DBU and CO2 + DBU + glycerol systems at the 303-353 K temperature range. The results illustrate the effect of DBU:glycerol ratio in CO2 absorption efficiency. CO2 solubility in pure DBU and glycerol was described with the Henry's law constants, which were further modeled with an empirical correlation. The CO2 + DBU + glycerol systems were modeled with a simple Posey type semi-empirical model. In addition, enthalpies of CO2 absorption in DBU + glycerol systems were estimated from the model parameters. The VLE measurements were conducted for the binary mixtures of water with [DBNH][OAc], DBN and DBU at the 303-353 K temperature range. The results of the studied systems indicate negative deviation from the Raoult's law. The measured VLE data were modeled with the Legendre and NRTL activity coefficient models.; Tassa vaitoskirjassa tutkittiin faasitasapainoja ja fysikaalisia ominaisuuksia tislautuvalle ioniselle nesteelle 1,5-diazabisyklo[4.3.0]non-5-enium asetaatille ([DBNH][OAc]) ja kytkeytyvalle ioniselle nesteelle hiilidioksidi (CO2) + 1,8-diazabisyklo-[5.4.0]-undek-7-eeni (DBU) + glyseroli seka naiden vesiseoksille.

DETRIMENTAL EFFECT OF CYCLOSPORINE ON INITIAL FUNCTION OF CADAVER RENAL ALLOGRAFTS FOLLOWING EXTENDED PRESERVATION Results of a randomized Prospective Study (1986)

We report herein the resul6ts of a randomized prospective trial comparing maintenance cyclosporine (CsA)-p prednisone immunosuppression to a regiment of aazathioprine-prednisone-antilymphocyte globulin (ALG) in cadaver renal transplant recipients. Fifty-six patients were entered into this study with 31 assigned to the ALG group and 25 to the CsA group. These two groups were well matched for most major determinants of graft outcome and the mean renal preservation time was 37 hr in each group. The incidence of acute tubular necrosis (ATN) was high in both groups (58% ALG, 72% CsA, NS). There were five cases of primary nonfunction in the CsA group and only one in the ALG group (P=.05). Of the kidneys that functioned, the mean seum creatimine nadir (1.5 vs. 2.2 mg/dl, P=.03) were both loss in the ALG group. The actuarial one-year graft survival rate in the ALG and CsA groups is 78% and 48%, respectively (P<.05). This difference is mainly due to the large number of primary nonfunctioning grafts in the latter group, which we attribute to the effect of CsA's nephrotoxicity superimposed on renal ischemia incurred prior to transplantation. These data emphasize that, in order to realize the full benefit of csA in cadaver transplantation, renewed emphasis must be placed on minimizing ischemic renal damage.
Linear IgA bullous dermatosis: a clinical study of 16 cases at National Taiwan University Hospital (2010)

Background: Linear immunoglobulin A bullous dermatosis (LABD) is a rare autoimmune subepidermal bullous disease. It is defined by continuous linear deposition of IgA in the basement membrane zone on direct immunofluorescence microscopy. The clinical presentations of LABD may mimic other diseases, and data in Taiwanese populations are still lacking. The current study aims to examine LABD status in Taiwan. Methods: We reviewed the database at our institute from 1995 to 2008. The gold standard for the diagnosis of LABD is based on continuous linear depositions of IgA in the basement membrane zone on direct immunofluorescence. Results: A total of 16 LABD patients were identified. Mean age at diagnosis was 55 years, and most (> 80%) occurred after the fourth decade. The trunk was most commonly involved (76%). However, in contrast to previous reports, the mucosal involvement was rare in our series (18%). Initial impressions were dermatitis herpetiformis in 8 patients (50%), bullous pemphigoid in 4 patients (25%), and vasculitis, varicella, and pemphigus vulgaris in the remaining 4 patients (25%). Four patients reported a history of drug ingestion shortly before the onset of the disease, and all recovered after discontinuing the offending drugs. One of them had griseofulvin-associated LABD, a case not reported previously. The other three drugs were rifampin, vancomycin and gemcitabine. Among the various regimens, dapsone (100 mg) twice a day achieved the best treatment response in the five treated patients. Conclusion: The rare and diverse presentations of LABD highlight the importance of our study results in aiding clinical diagnosis and planning treatment strategies.
Analytical and empirical analysis of countermeasures to traffic analysis attacks (2003)

We study countermeasures to traffic analysis attacks. A common strategy for such countermeasures is link padding. We consider systems where payload traffic is padded so that packets have either constant inter-arrival times or variable inter-arrival times. The adversary applies statistical recognition techniques to detect the payload traffic rates by using statistical measures like sample mean, sample variance, or sample entropy. We evaluate quantitatively the ability of the adversary to make a correct detection and derive closed-form formulas for the detection rate based on analytical models. Extensive experiments were carried out to validate the system performance predicted by the analytical method. Based on the systematic evaluations, we develop design guidelines for the proper configuration of a system in order to minimize the detection rate

SYTO16 labelling and flow cytometry of Mycobacterium avium (1997)

Mycobacterium avium cells were harvested from agar at different stages of their growth cycle, exposed to the minimum inhibitory concentration of isoniazid (INH) for 24 h and labelled with the fluorescent nucleic acid stain SYTO16. INH exposure led to a > 10-fold increase in the intensity of labelling in the majority of cells, and revealed discrete fluorescence peaks that were consistent with development of filamentous multinucleate cells during the growth cycle. Similar enhancement of labelling was observed in unfixed INH-treated cells viewed by fluorescence microscopy. INH appears to increase the permeability of Myco. avium cells to SYTO16. A combination of growth cycle-defined inocula, labelling with the new generation of fluorescent dyes and flow cytometry provides new opportunities to study the interrelationships between growth cycle events and antimicrobial susceptibility of mycobacteria.
Recent developments in large-scale and parallel matrix computations and their applications to linear control problems (2002)

An overview of some of the existing important Krylov subspace methods that have been developed in the last few years for large-scale solutions of control problems, is given. These algorithms are suitable for large and sparse problems. Also included is a statement of a parallel-block algorithm for the Sylvester-observer matrix equation, suitable for high-performance computing. This is an emerging area of research. A need for an urgent and expanded research in the area of large-scale and parallel computations in control has been outlined in the NSF panel report (1988).< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Energy distributions of field emitted electrons from carbide tips and tungsten tips with diamondlike carbon coatings (1996)

We have measured the energy distributions of electrons field emitted from tungsten carbide, HfC〈100〉, and ZrC〈100〉 tips, and tungsten field emitters with diamondlike carbon coatings. Multiple-peaked energy distributions were observed from instability induced emission sites on the carbide tips. Energy distributions of electrons field emitted from the diamondlike carbon coated tungsten tips were broader than those from metal tips. They also showed a shift towards lower energies with increases in the emission current.
Single Gas Permeation on γ-Alumina Ceramic Support (2016)

This study examines the characterization (SEM-EDXA observation, BET measurement) and gas transport through a commercial tubular alumina mesoporous (20 and 500 Co) support. Single gas permeation of helium (He), hydrogen (H2), nitrogen (N2) and carbon dioxide (CO2) was measured at a temperature of 450°C and feed pressures between 0.85 up to 1.0 bar. Observation of the permeance of the alumina support revealed that the transport of the gases under these conditions is governed by Knudsen diffusion. Selectivity of 2.7 was obtained for He/N2 at 1 bar. The selectivity obtained is comparable to the theoretical Knudsen value (2.65) for He/N2.
Spatial multi-database topological continuity and indexing: a step towards seamless GIS data interoperability (1998)

This paper presents some problems and solutions concerning the federation of several geographical databases, in the context of interoperability. When a multi-database query is executed, it is important to route it only to sites which are likely to contribute to the answer, whatever the fragmentation might be, geographical, thematic or heterogeneous. Secondly, when the answer implies several spatial databases, it is important that not only boundary alignment is achieved, but also topological continuity. After describing several general problems and concepts about distributed spatial databases and their integration, structures for spatial indexing in multi-database systems are described, giving emphasis to local and global spatial indices. An r -tree-like structure is proposed for organizing those global indices. Geographical fragmentation presents disadvantages to artificially cut geographical objects, such as roads, rivers, etc. In other words, some objects, called fragmented objects, have the particularity of having several database identifiers (one per site) and a mechanism must be provided in order to re-construct those objects when necessary. In this paper, special tools are presented in order to ensure continuity of fragmented objects, semantically (at the level of identifiers), topologically (at the level of data structure) and geometrically (at the level of coordinates, possibly with errors). In order to accelerate queries against fragmented objects, some adjacency tables must be constructed. Truly seamless GIS data will only exist on the Internet once spatial continuity is ensured.
From bag ladies to bathing apes: Japanese interventions in British sartorial culture (2013)

Abstract Since 1980 Japanese designers have built a solid, if understated, presence in the United Kingdom. This chapter examines the country’s interventions in British sartorial culture in the arenas of designer fashion, high-street apparel and sub-cultural style from three inter-related perspectives. The first considers the curatorial context of exhibitions that featured a cohort of avant-garde designers. The second addresses contrasting commercial strategies adopted by Japanese designers that involved mobilizations of traditional culture as ‘unique selling points’ and infiltration of the domestic market through collaborations with British apparel makers. The third documents visual consumption of creative outputs mediated through the styling regimes of the fashion periodical, and identifies a gendered differentiation in representations of Japanese fashion design. The conclusion suggests that, in an increasingly cosmopolitan creative milieu, interpretations of British sartorial heritage have become the province of ‘outsiders looking in’.
Expression of SPARC/osteonectin/BM4O in the human gut: Predominance in the stroma of the remodeling distal intestine (2001)

SPARC is a glycoprotein of the extracellular matrix that exhibits a number of biological functions such as disruption of cell adhesion and modulation of matrix metalloprotease expression. These properties, in concert with the expression of the molecule during development, repair, and neoplastic progression, suggest that SPARC has an important role in remodeling in a variety of tissues. However, the role of SPARC in the intestine is unclear since the development expression and tissular origin of SPARC in this organ appears to be species-dependent. As a first step to investigate the function of SPARC in the tissues of the intestine, we have analyzed its expression at the protein and mRNA levels in the human fetal and adult small intestinal and colonic mucosa as well as in intestinal cell models. Our results show that SPARC expression is differentially regulated during development and along the length of the human intestine. In the colon, SPARC was predominantly found at the epithelial–mesenchymal interface at the fetal stage, below detection levels in the normal adult, but re-expressed in the stroma of colonic tumors. In the small intestine, low levels of SPARC expression were observed at an early stage of morphogenesis (between 9 and 11 weeks) but expression was not detected at subsequent developmental stages nor was it induced in the mucosa of Crohn's disease. While SPARC appeared to be produced mainly by mesenchymal and stromal cells in the intact intestine it was not detected in colon cancer cells. Taken together, these results indicate that SPARC is subject to an onco-fetal pattern of expression in the stroma of the colonic mucosa while its expression is much more restricted in the small intestine, suggesting a differential involvement of this molecule in the extracellular matrix remodeling occurring along the length of the developing and diseased human intestinal mucosa.

Key distribution schemes (2002)

A key distribution scheme is a method used to distribute off-line initial private pieces of information among a set of users, such that each group of them can compute a common key for secure conference. This information is generated and distributed by a trusted server which is active only at the distribution phase. Key distribution is a central problem in cryptographic systems, and is a major component of the security subsystem of distributed systems, communication systems, and data networks. We consider the case in which users are allowed to interact after receiving the keys.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
