Light injection in SOI microwaveguides using high-efficiency grating couplers (2006)

An experimental characterization of the grating couplers for sub-micrometer silicon-on-insulator (SOI) waveguides is presented. The grating couplers have been designed, realized, and characterized for the +1 diffraction order at an operating wavelength of 1.31 /spl mu/m for TE polarization. At the resonant angle, a coupling efficiency higher than 55% has been measured. The angular coupling range and the wavelength tolerance have been evaluated to 3/spl deg/ and 20 nm, respectively. The grating coupler is followed by a taper, and about 50% of the input power at 1.31 /spl mu/m is coupled into sub-micrometer rib and strip SOI waveguides. The ration between light power decoupled toward the cladding and light power decoupled toward the substrate is about three.

New therapeutic approaches to revering insuiln resistance (1998)

Insulin resistance may be associated with hypertension and additional cardiovascular disease risk factors. Troglitazone, a thiazolidinedione, is an insulin sensitizing agent that has recently been approved by the USA Food and Drug Administration for the treatment of type II diabetes. Thiazolidinediones and other agents that increase insulin sensitivity, and lipid lowering drugs attenuate the development of hypertension in animal models and in limited clinical studies.
Extended major histocompatibility complex haplotypes in type I diabetes mellitus. (1984)

We have studied major histocompatibility complex markers in Caucasian patients with type I diabetes mellitus and their families. The frequencies of extended haplotypes that were composed of specific HLA-B, HLA-DR, BF, C2, C4A, and C4B allelic combinations, which occurred more commonly than expected, were compared on random diabetic and normal chromosomes in the study families. We demonstrated that all of the previously recognized increases in HLA-B8, B18, B15, DR3, and perhaps DR4 could be ascribed to the increase among diabetic haplotypes of a few extended haplotypes: [HLA B8, DR3, SC01, GLO2]; [HLA-B18, DR3, F1C30]; [HLA-B15, DR4, SC33]; and [HLA-BW38, DR4, SC21]. In fact, HLA-DR3 on nonextended haplotypes was "protective", with a relative risk considerably less than 1.0. There was a paucity or absence among diabetic patients of several extended haplotypes of normal chromosomes, notably [HLA-B7, DR2, SC31] and [HLA-BW44, DR4, SC30]. The extended haplotype [HLA-BW38, DR4, SC21] is found only in Ashkenazi Jewish patients, which suggests that extended haplotypes mark specific mutations that arise in defined ethnic groups. The data show that no known MHC allele, including HLA-DR3 and possibly HLA-DR4, is per se a marker for or itself a susceptibility gene for type I diabetes. Rather, extended haplotypes, with relatively fixed alleles, are either carriers or noncarriers of susceptibility genes for this disease. Thus, the increased frequency (association) or the decreased frequency (protection) of individual MHC alleles is largely explainable by these extended haplotypes.
DYEING OF POLY (ETHYLENE TEREPHTHALATE) PRE-TREATED WITH SOLVENTS (1978)

The amorphous contents in poly (ethylene terephthalate) (PET) films pre-treated with 18 kinds of solvents at 106-135°C for 3hours were determined by means of an infrared spectrophotometer. Approximately linear relationships were found between the amorphous contents in PET films and the shrinkage of PET filament yarns, or birefringences of PET films, respectively.Partition coefficients, diffusion coefficients and saturation values of Disperse Red 15 for the above pre-treated PET films were measured in iso-octane dye baths at 85-105°C, and correlated with the amorphous contents in the above PET films. These values increased approximately linearly with the amorphous contents. In particular, pre-treatment with solvents of which solubility parameter were around 10 or 12 gave higher values of partition coefficients, diffusion coefficients and saturation values.Heats of dyeing increased approximately linearly with the amorphous contents. However, activation energies for diffusion of dyes and energies required to make a path which dyes molecules moved through, decreased linearly with the amorphous contents.Dyeing properties of Disperse Red 15 on the PET films were dependent on the pre-treatment temperature even for the same amorphous contents of the films. The present results show that amorphous regions of PET having the same amorphous contents may be structurally different in certain cases.
IRON: ITS INTRACELLULAR LOCALIZATION AND POSSIBLE ROLE IN CELL DIVISION (1970)

When HeLa cells are fixed with ethanol, extracted with 0.1 N HCl, and incinerated at 540 degrees C, all organic constituents and all ions studied are removed with the exception of iron. The gross outlines of cell structures are preserved and high concentrations of residual ash in interphase nucleoli and mitotic chromosomes suggest that there may be a shift in iron salts during the cell cycle. Experiments with cells isotopically labeled in proteins, nucleic acids, lipids, and polysaccharides indicate that the iron is bound to a polysaccharide. Addition of iron chelating agents to living cells causes a selective inhibition of DNA synthesis. These data suggest that iron may play a crucial role in the mitotic process.
Place, social relations and the fear of crime: a review (2000)

This article reviews the literature on fear of crime of interest to the geographical and environmental disciplines. After discussing definitional and methodological issues, the article focuses on accounts which link fear with the physical environment, and then on fear, social identity and exclusion. It considers the significance of one area of recent research that attempts to link place and social relations through developing local ethnographies of fear. The review concludes with some suggestions for building upon this work, and highlights the relevance of the geographical themes discussed to current policy debates.
New considerations for the pathogenesis of endometriosis (2002)

There is evidence to suggest that alterations in the immune response, whether genetically transmitted or environmentally induced, predispose women to the ectopic implantation of endometrial cells transported into the peritoneal cavity by way of retrograde menstruation. This predisposition may exist because of an impaired peritoneal clearing of endometrial cells and fragments or because of pathological angiogenesis.
Performance of jump connection neural networks applied to a simplified pattern recognition problem (2000)

In this note we present and discuss results of experiments comparing the performance of jump connection neural network architectures applied to a simplified multifont recognition problem. The experiments have been run for the increasing number of data elements in the training set and for varying number of nodes in the hidden layer.
Modélisation Spatio-Temporelle des scènes dynamiques 3D à partir de données visuelles (2010)

Space-time models (or 4D models) are descriptions of dynamic activities of the real world, that can be stored, analyzed by computers and visualized at distance. Digital imaging and computing technologies of today have matured to a level capable of recording human activities in rich three dimensional detail, and across a length of time. Such photographic 4D models shall in the future be the equivalents of photographic video of today, and produce equivalent artifacts of human culture and heritage. In this thesis, we are concerned with the problem of building such space-time models from the bottoms up through a multi-camera environment. Our contributions are primarily towards estimating motion, both at a coarse and at a dense level from surfaces reconstructed in this fashion.
Stimulating Ideas Through Creative Software (1994)

A central task of management is decision making and a crucial aspect of decision making is having good alternatives from which to choose. This paper investigates whether computer-based procedures for idea generation can help individuals to develop solution alternatives more creatively. Our conceptual framework considers creative processes, environments, outputs, and individuals. In particular, generating alternatives is viewed as a process of “making connections” —internal connections among problem elements and external connections between a problem and its environment. We have developed a computer program (GENI) which incorporates a variety of techniques to assist in making these different types of connections. The program is described and an experimental test with several managerial problems is presented. The results show that use of the program leads to the development of significantly more creative alternatives than does a control treatment. There is an amplification effect in that the performance of the more creative individuals is improved the most. Thus the findings suggest that computerized idea generation leads to more creative alternatives resulting in potentially better managerial decisions.
Surface Freezing on Patterned Substrates (2000)

We show that the structure of a substrate pattern drastically influences the nature of surface freezing. By using phenomenological theory and computer simulations of a hard sphere fluid next to a substrate formed by a periodic array of fixed spheres, we find that a pattern which is commensurate with the bulk crystal induces complete surface freezing through a cascade of layering transitions. A rhombic pattern, on the other hand, either generates a crystalline sheet which is unstable as a bulk phase or prohibits surface freezing completely.
High performance microstrip networks for multibeam and reconfigurable operation in mobile-radio systems (2002)

This paper presents the development of high performance multiport hybrid networks based on the Butler matrix concept in thick film microstrip technology to provide the multibeam and reconfigurable operation of antennas of DCS 1800 (ground mobile) base stations. This work was performed to meet the increasing demand for mobile communications that calls for the use of advanced components to improve the electrical performance and reduce the size of transceivers, in view of the integration of ground and satellite communication equipments. In what follows a survey of the various applications of these multiport networks is presented. Furthermore, the possibility of increasing the operation flexibility suggested the use of specific components able to carry out a close control of the phase. With regard to this fact, innovating types of phase-shifters, providing a very accurate slope equalization of the phase over a specified frequency band, were developed. All designs were performed using CAD Libra (software by Eesof) to operate over the 1.7-1.9 GHz band and prototypes were manufactured on Rogers RT6006 and RT5880 Duroid substrates. Finally, the microstrip technology used for DCS applications at 1.8 GHz can easily be transferred to satellite mobile systems at 1.6 GHz and to cellular based PCN (2-2.5 GHz band).
Induced-pluripotent stem cells seeded acellular peripheral nerve graft as “autologous nerve graft” (2010)

The hypothesis is that induced pluripotent stem cells (iPSC) derived Schwann cells and/or macrophages can be transplanted into acellular nerve graft in repairing injured nervous system. The efficiency of iPSC seeded acellular nerve graft may mimic the autologous peripheral nerve graft.
Pondering over some blunders on scientificity in diabetic researches by integrated Chinese and western medicine (2004)

Scientificity was emphasized in researches on diabetes mellitus in integrated traditional Chinese and western medicine abroad. In clinical researches, random and double-blind method, placebo control and auto-cross-over experiment were employed, and the diet, activity, drug dosage and body weight were under strict control, although such kind of researches was rare. During the past few decades, there were also some good achievements in the researches on diabetes mellitus in integrated traditional Chinese and western medicine in China, but most of the researches were duplicated work at low level. There existed some problems, such as the selection of investigated objects, control of the facts besides of the drugs, randomized grouping, blind method, auto-cross-over control, integrated research of multi-center, selection of indexes, methods of index detection, selection of complex prescription, single drug or monome, animal model, etc. The scientificity of the researches in China should be further improved.
Epigenetic regulation of the expression of the novel stem cell marker CDCP1 in cancer cells (2006)

CDCP1 is a novel stem cell marker that is expressed in several types of cancer. The mechanisms by which CDCP1 expression is regulated, and the clinical implications of this marker, have not been clarified. In this report, we examine the epigenetic regulation of CDCP1 expression in cell lines and clinical samples from patients with breast cancer. Many CpG sequences were localized around the transcription initiation site of CDCP1. These CpG motifs were found to be poorly methylated in cell lines with high levels of CDCP1 expression and heavily methylated in cell lines with low levels of CDCP1 expression. The in vitro methylation of CpG sites decreased CDCP1 promoter activity, and the addition of a demethylating reagent restored activity. In 25 breast cancer samples, an inverse correlation was noted between the CDCP1 expression level and the proportion of methylated to non-methylated CpG sites. Tumours with high-level CDCP1 expression showed higher levels of proliferation, as revealed by immunohistochemical detection of the MIB-1 antigen, than tumours with low-level CDCP1 expression. These findings indicate that the expression of CDCP1 is regulated by methylation of its promoter region in tumours. CDCP1 expression may prove to be useful in the further characterization of cancers.
Digital detection of the flux-gate sensor output signal (1994)

This paper describes an experiment where the flux-gate sensor broad band output signal is digitized with 8-bit resolution at a high rate, and subsequently numerically analysed in order to extract information on the external magnetic field. The results show that it is feasible to obtain a noise level of 1 nT for a data output rate of 100 Hz. The method will allow construction of a magnetometer based entirely on digital techniques, with only a minimum of analogue circuits.
Using information criteria in Dempster-Shafer's basic belief assignment (1999)

Within the framework of pattern recognition, many methods of classification were developed. More recently, techniques using the Dempster-Shafer's theory or evidence theory tried to deal with the problem related to the management of the uncertainty and data fusion. We propose a classification method based on Dempster-Shafer's theory and information criteria. After an original basic belief assignment method, we introduce an attenuation factor of belief functions based on the dissimilarity between probability distributions. Results on synthetic and real world data sets are given in order to illustrate the proposed methodology.

Controlled formation of metallic nanowires via Au nanoparticle ac trapping (2007)

Applying ac voltages, we trapped gold nanoparticles between microfabricated electrodes under well-defined conditions. We demonstrate that the nanoparticles can be controllably fused together to form homogeneous gold nanowires with pre-defined diameters and conductance values. Whereas electromigration is known to form a gap when a dc voltage is applied, this ac technique achieves the opposite, thereby completing the toolkit for the fabrication of nanoscale junctions.
Switching with PASSPORT (1991)

Discusses how the implementation of PASSPORT has made switching between services easier in one particular library system. Considers specific software/hardware specifications, the creation of a new logon script, and the solution to a problem of software installation. Concludes that PASSPORT has made searching OPAC as convenient as using the OCLC database.
Study of Date Palm Stem as Raw Material in Preparation of Activated Carbon (2008)

Activated carbon adsorbent was prepared using Omani date palm tree stem as a precursor. Precursor samples were subjected to thermal treatment (at 400, 500 and 600 oC) before or after impregnation with either H3PO4 (85 wt %) or KOH (3 wt %). The activated carbon obtained was characterized by BET (surface area and porosity), Gas Pycnometry (true density) and SEM (texture). Sample subjected to carbonization, without chemical activation, exhibited low surface areas ~ 1.0 m2/g at 400 and 500 oC and 124 m2/g at 600 oC. Further treatment of such samples with either the acid or the base did not show improvement in surface area or other properties. Impregnations of the precursor with acid before carbonization significantly improved the surface area to as high as 1,100 m2/g at a carbonization temperature of 500 oC. Thus, activated carbon with a moderate surface area could be produced from date palm stem using low carbonization temperature.
Gothenburg Osseointegrated Hip Arthroplasty (1998)

The culmination of more than 10 years of laboratory and clinical research has been the clinical trial of a novel hip arthroplasty for osseointegration. The femoral component of this Gothenburg hip is a neck retaining, threaded fixture with rotational symmetry, produced in commercially pure titanium with a specific surface texture. Proximally, a standard orthopaedic taper trunnion mates with a 28-mm diameter zirconia head that articulates against the acetabular component. The latter is also of textured commercially pure titanium, encapsulating a thick ultra high molecular weight polyethylene liner. Dedicated alignment guides and cutting instruments ensure accurate bone preparation and implant placement. Limited clinical trials commenced in 1992 and expanded to multicenter clinical trials in 1997. Every hip has been monitored with radiostereometry to measure migration to an accuracy of 0.1 mm. All calcar implanted femoral components show excellent function at 4 to 5 years followup, with no migration revealed by radiostereometry.
[Effectiveness of treatment with transfer of autologous or allogenic LAK cells combined with rIL-2 in 121 patients with malignant pleural effusion]. (1993)

Lymphocytes isolated from malignant pleural effusions of patients with advanced lung cancer or from allogenic peripheral blood of healthy donors were induced to become LAK cells after in vitro culture with rIL-2. One hundred and twenty-one patients with malignant effusions were treated by intrapleural administration of autologous or allogenic LAK cells combined with rIL-2. The effusions disappeared in 71 (58.6%) patients and significantly decreased in 45 (36.2%) patients. Five patients did not respond to the treatment. Tumor cells in pleural effusions disappeared or significantly decreased and lymphocytes significantly increased in all responders. Except for transient chill and/or fever in 102 patients, no serious side effect was found. The results indicate that transfer of autologous or allogenic LAK cells combined with rIL-2 in the treatment of patients with malignant pleural effusions due to advanced lung cancer is feasible effective, and safe.
Automatic resource and service management for ubiquitous computing environments (2004)

The high degree of dynamism and heterogeneity of the resources involved in a pervasive computing environment makes service adaptation and interoperability a difficult task. We present UBIDEV, a service framework that faces the heterogeneity problem by hiding at the application level the dynamism of the underlying environment. We describe the UBIDEV architecture focusing on the description and the management of services and resources. We also describe how this approach decreases the complexity of the design and development of service-oriented applications. A prototype implementation of a unified messaging system is presented as a validation of the architectural design.
Structure and tunnel magnetoresistance in Fe/MgF2/Co junctions with an oxide seed layer on an Fe bottom electrode (2002)

Fe/MgF 2 / Co magnetic tunnel junctions (MTJs) with an oxide seed layer (MgO, Fe–O) inserted between an Fe bottom electrode and a MgF2 barrier layer have been prepared through the use of molecular beam epitaxy, and the effects of the seed layers on structure of subsequently deposited MgF2 barrier layers and tunnel magnetoresistance (TMR) have been investigated. The crystallographic orientation of MgF2 layers depends significantly on the seed layers, and furthermore, it has been found that the surface roughness of MgF2 layer is reduced by inserting a MgO seed layer. In Fe/MgF2 (3–12 nm)/Co MTJs without any seed layer, top Fe and bottom Co electrodes contact each other through pin holes in MgF2 layers. On the other hand, however, Fe and Co electrodes are separated both magnetically and electrically in Fe/MgO (0.3–0.5 nm)/MgF2 (2–5 nm)/Co MTJs, i.e., MgF2-based MTJs have successfully been prepared by inserting a thin MgO seed layer, resulting in TMR of about 10% observed at 4.2 K.
