Adjustable speed generators for wind turbines based on doubly-fed induction machines and 4-quadrant IGBT converters linked to the rotor (2002)

Wind turbines are being built at power levels above 1.5 MW. Higher power levels are being anticipated for offshore applications. To limit mechanical stresses and power surges in these high power systems, speed control is necessary. The doubly-fed induction generator (DFIG) system is investigated as a viable alternative to adjust speed over a wide range while keeping the cost of the power converters minimal. A four-quadrant IGBT AC-to-AC converter is used to feed power bi-directionally to the rotor circuit. Decoupled control of active and reactive power can be realized using the dynamic model of the DFIG. Simulations and measurements confirm the validity of the model and the viability of the DFIG wind turbine.

Zoladex is as well tolerated and as effective as danazol in the treatment of premenopausal women with endometriosis.
A Study on the Dyeing Method of Silk/Polyester Blend Fabrics (1991)

The textile fabric have the functions of sanitation, decoration, wearing style and washing in the practical use. Among various texitle fiber, silk has less utilities than synthetic fiber in practical use although silk has good benefits of the high quality. Thus no textile fiber, neither natural nor synthetic, has all the functions. In this sence, many blend yarns have been improved various functions of fabric. However, this has been disturbed with the problem of dyeing, especially in the case of blend fabric of silk. In this study, we dyed silk/PET blend fabric in one step useing one bath dyeing method by acid dyes/disperse dyes. The results of the experiments can be summarized as follows; 1) Yellow index of silk fabric treated at increased about 7.8 (color difference 4.5 NBS) and whiteness decrease about 5%. 2) Both elongation and tensile strength of silk fabric treated at of pH 5-6 decreased about 10% and tensile strength of silk spun yarn treated at of pH 10 have little changed. 3) While silk/PET blend frbric dyeing, silk soiling of disperse dyes causes from difference of dyeing rate and degree of silk soiling with dyes. 4) Fastness and soiling of silk/PET blend fabric dyed by one bath dyeing method of acid dyes/disperse dyes was same as two bath dyeing method.
A high spatial resolution distributed optical fiber sensor for high-temperature measurements (1997)

One of the advantages of the use of optical fibers for sensing is their ability to perform distributed measurements. Several distributed sensors that measure temperature along optical fibers are already commercially available. All of them are based on Raman thermometry. However, the spatial resolution that they achieve is limited to 1 m, making them unsuitable for applications where higher spatial resolution is needed. Also, their temperature range is very dependent on the behavior of fibers at high temperature, a subject which still needs investigation. In this article, we present a distributed optical fiber sensor that addresses these two issues. On one hand, the combination of Raman thermometry with the time-correlated single-photon counting technique permits the achievement of high spatial resolutions (0.1 m). On the other hand, the use of specially coated fibers allows measurement of high temperatures. We have investigated the system temperature sensitivity and have evaluated the measurement errors introduced by the high-temperature behavior of carbon- and gold-coated fibers. We demonstrate that the system is very appropriate for high-temperature distributed measurements with high spatial resolution.
Demonstration of Pinhole Laser Beam Profiling Using a Digital Micromirror Device (2009)

Demonstrated for the first time, to the best of the authors' knowledge, is two-dimensional (2-D) pinhole laser beam profiling using a Texas Instruments visible band digital micromirror device (DMD). Software controlled micromirror digital tilt positions across the DMD plane create a moving pinhole for sampling an arbitrary distribution laser beam power profile. A 532-nm 0.5-W laser coupled to an optically addressed nematic liquid crystal spatial light modulator is used to generate a laser beam black-and-white high-resolution test line pattern having a 62.5-mum linewidth. The test pattern is successfully profiled using a DMD formed 27.36 mum times 27.36 mum pinhole. Demonstrated for the first time is 2-D knife-edge DMD-based profiling of an ultraviolet 337-nm 4-ns pulsewidth 10-Hz pulsed laser beam.

Multipotent Menstrual Blood Stromal Stem Cells: Isolation, Characterization, and Differentiation (2008)

The stromal stem cell fraction of many tissues and organs has demonstrated to exhibit stem cell properties such as the capability of self-renewal and multipotency, allowing for multilineage differentiation. In this study, we characterize a population of stromal stem cells derived from menstrual blood (MenSCs). We demonstrate that MenSCs are easily expandable to clinical relevance and express multipotent markers such as Oct-4, SSEA-4, and c-kit at the molecular and cellular level. Moreover, we demonstrate the multipotency of MenSCs by directionally differentiating MenSCs into chondrogenic, adipogenic, osteogenic, neurogenic, and cardiogenic cell lineages. These studies demonstrate the plasticity of MenSCs for potential research in regenerative medicine.
Nonlinear Optics in Semiconductors (1994)

The dream of the all-optical processing of information has motivated efforts over the past decade to create sensitive semiconductors that have large optical nonlinearities. Semiconductors have been the medium of choice in part because a well-developed materials technology has already been built around them. One can design semiconductor structures easily and predict their performance accurately.
Functional neuroimaging studies of bipolar disorder: Examining the wide clinical spectrum in the search for disease endophenotypes (2009)

Bipolar disorder (BP) is among the top ten most disabling illnesses worldwide. This review includes findings from recent studies employing functional neuroimaging to examine functional abnormalities in neural systems underlying core domains of the psychopathology in BP: emotion processing, emotion regulation and executive control, and common comorbid features of BP, that are relevant to the wide spectrum of BP rather than focused on the more traditional BPI subtype, and that may facilitate future identification of diagnostically-relevant biomarkers of the disorder. In addition, an emerging number of studies are reviewed that demonstrate the use of neuroimaging to elucidate biomarkers whose identification may help to (1) identify at-risk individuals who will subsequently develop the illness to facilitate early intervention, (2) identify targets for treatment and markers of treatment response. The use of newer neuroimaging techniques and potential confounds of psychotropic medication upon neuroimaging findings in BP are also examined. These approaches will help to improve diagnosis and the mental well-being of all individuals with BP.
Improved quality factor of Hetero Acoustic Layer (HAL) SAW resonator combining LiTaO<sub>3</sub> thin plate and quartz substrate (2017)

For mobile communication, acoustic wave filters are being continuously required better steepness of a passband and a smaller temperature coefficient of frequency (TCF). Recently, various Hetero Acoustic Layer (HAL) types of surface acoustic wave (SAW) devices were reported by different groups including us [1-5]. HAL SAW devices inherently have many variations of structure and a lot of potentials. In this study, we report the bandwidth (BW) and impedance ratio (Z ratio) of different designs of HAL SAW resonators using a LiTaO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sub> thin plate on a quartz substrates.
Marketing readiness of websites and organisational performance in Australia and New Zealand: a discussion of pre-test findings (2004)

\n\t\t\t\t\tThe Web played a role in the burst of economic activity that occurred in the late 1990s that saw company values dramatically rise and fall, business and government processes reshaped, traditional marketing media challenged, and much written concerning the benefits to customers from the adoption of what was initially termed e-commerce. Initial empirical studies of Australian and New Zealand business and government use of the Web found that while the Web was used for marketing communication, it was not as favoured as trade press reports suggested as a marketing transaction channel, nor for relationship management. This paper, which reports the findings of a pre-test of the self-administered online questionnaire stage of a three-phase study, suggests that little has changed in organisational use of the Web in Australia and New Zealand since the late 1990s, even among high network traffic organisations. The pre-test findings reported do not present a clear picture concerning the influence of strategic use of traditional and online marketing mix elements on organisational performance. Analysis employing a Marketing Readiness of Website Indicator (MRWI) content analysis tool is shown not to predict organisational performance as hypothesised.<br />\n\t\t\t\t
Dynamic access control framework based on events: a demonstration (2004)

Access control policies in the e-commerce domain can be quite complex, affecting the response time provided to the users. We describe an event-based access control system that can potentially reduce the customer response time by pre-computing the access control rights based on policies.
Optical information processing characteristics of the microchannel spatial light modulator (1981)

The microchannel spatial light modulator (MSLM) is a versatile, highly sensitive, and optically addressed modulator that is well suited for low-light level real-time optical information processing. The image processing operations that can be achieved with the MSLM include contrast reversal, contrast enhancement, edge enhancement, image addition and subtraction, analog and digital intensity level thresholding, and binary level logic operations such as AND, OR, EXCLUSIVE OR, and NOR. Several of these operations are demonstrated herein. Recent prototype MSLMs have exhibited a halfwave exposure of 2.2 nJ/cm(2), an optical information storage time of more than two months, and a framing rate of 40 Hz with full modulation depth (200 Hz with 20% modulation depth). The role of secondary electron emission in the operation of the MSLM is discussed, and design modifications that would yield a spatial resolution of ~10 cycles/mm at the 50% point on an MTF curve are proposed.
Unexpected Epithelial Membrane Antigen (EMA) and Cytokeratin Expression in a Case of Infantile Acute Monoblastic Leukaemia (1996)

A previously healthy eleven month old male Malay infant presented with fever, upper respiratory tract infection and right knee swelling. Pallor, bilateral proptosis, hepatosplenomegaly, multiple scalp swellings and a right cheek swelling were observed. Investigations revealed that he had acute monoblastic leukemia or FAB M5a. Immunophenotyping by flow cytometry showed that the blast cells were positive for CD45, CD13, CD33, HLA-DR, CDllc, CD71, EMA, and Cytokeratin. They were negative for CD34, CD19, CD10, CD22, CD2, CD3, CD4, CD7, CD8, CD61, NK, Glycophorin A, and CD14. The monoblasts were used to evaluate anti-EMA and anti-cytokeratin. They were unexpectedly found to be positive. Acute monoblastic leukaemias are well known to show extramedullary infiltration and this may be their primary mode of presentation. Thus, in immunochemostry, when using EMA and cytokeratin expression in the differential diagnosis of neoplastic diseases, it is important to consider that monoblasts may express these markers as illustrated by this case.
Multiwavelength lasers fabricated by a novel impurity-free quantum-well intermixing technology (1999)

Using impurity free vacancy enhanced disordering (IFVD), the shift in the band gap of Al<SUB>0.3</SUB>Ga<SUB>0.7</SUB>As/GaAs QW structures can be precisely controlled by an Al layer buried between a spin-on silica film and wet-oxidized GaAs surface. The blue shift in wavelength of Al<SUB>0.3</SUB>Ga<SUB>0.7</SUB>As/GaAs QW photoluminescence (PL) depends linearly on the thickness of the buried Al layer. By changing the Al layer thickness, the PL peak wavelength can be tuned from 7870 angstrom for the as-grown sample to 7300 angstrom and 7050 angstrom after 20s and 45s rapid thermal annealing at 850°C respectively. Applying this technology, three wavelength lasers were successfully fabricated in a single chip. The laser is a GaAs/Al<SUB>0.3</SUB>Ga<SUB>0.7</SUB>As three quantum well GRIN-SCH structure. Al layers with different thickness, i.e., no Al, 200 angstrom and 300 angstrom thick respectively, were buried between the oxidized GaAs surface and the silica film by two step photo-lithography and lift- off in three adjacent regions with 200 μm spacing. After one step rapid thermal annealing, the wafer was processed into 6 μm oxide-strip lasers. At room temperature the intermixed lasers covered with different thickness of Al layer show different lasing wavelengths. All the lasers have similar threshold current and slope efficiency.
Effects of interleukin 6 on megakaryocytes and on canine platelet function (1994)

The multifunctional cytokine interleukin 6 (IL-6) is a potent promoter of megakaryocytic maturation in vitro. In vivo, IL-6 has similar effects on the maturation of megakaryocytes, as shown by enhancing size, ploidy and platelet production. IL-6 is capable of augmenting the platelet count in both normal animals and those with reduced megakaryocyte mass; ongoing clinical trials suggest a similar thrombocytopoietic effect in man. Moreover, IL-6 alters platelet function, rendering them more sensitive to activation by thrombin and platelet activating factor. Finally, IL-6 promotes increases in plasma fibrinogen and von Willebrand factor, and a decrease in free protein S concentration. These modifications of the platelet and coagulant phases of the clotting mechanism may result in an overall prohemostatic tendency, which may prove beneficial for the amelioration of bleeding propensity following chemotherapy. However, additional investigation will be required to determine if IL-6-mediated alterations of hemostasis may lead to pathologic thrombosis.
NLRX1 Is a Multifaceted and Enigmatic Regulator of Immune System Function (2019)

Over the last decade, significant progress has been achieved in defining mechanisms underlying NLR regulation of immune system function. However, several NLR family members continue to defy our best attempts at characterization and routinely exhibit confounding data. This is particularly true for NLR family members that regulate signaling associated with the activation of other pattern recognition receptors. NLRX1 is a member of this NLR sub-group and acts as an enigmatic regulator of immune system function. NLRX1 has been shown to negatively regulate type-I interferon, attenuate pro-inflammatory NF-κB signaling, promote reactive oxygen species production, and modulate autophagy, cell death, and proliferation. However, the mechanism/s associated with NLRX1 modulation of these pathways is not fully understood and there are inconsistencies within the field. Likewise, it is highly likely that the full repertoire of biological functions impacted by NLRX1 are yet to be defined. Recent mouse studies have shown that NLRX1 significantly impacts a multitude of diseases, including cancer, virus infection, osteoarthritis, traumatic brain injury, and inflammatory bowel disease. Thus, it is essential that the underlying mechanism associated with NLRX1 function in each of these diseases be robustly defined. Here, we summarize the current progress in understanding mechanisms associated with NLRX1 function. We also offer insight into both unique and overlapping mechanisms regulated by NLRX1 that likely contribute to disease pathobiology. Ultimately, we believe that an improved understanding of NLRX1 will result in better defined mechanisms associated with immune system attenuation and the resolution of inflammation in a myriad of diseases.

Intelligent Personal Assistants Based on Internet of Things Approaches (2016)

The Internet has emerged as a key network to make information accessible quickly and easily, revolutionizing how people communicate and interact with the world. The information available on the Internet about a given subject may be extensive, allowing the development of new solutions to solve people's day-to-day problems. One such solution is the proposal of intelligent personal assistants (IPAs), which are software agents that can assist people in many of their daily activities. IPAs are capable of accessing information from databases to guide people through different tasks, deploying a learning mechanism to acquire new information on user performance. IPAs can improve the assistance they offer to users by collecting information autonomously from objects that are available in the surrounding environment. To make this idea feasible, IPAs could be integrated into ubiquitous computing environments in an Internet of Things (IoT) context. Therefore, it is necessary to integrate wireless sensor networks with the Internet properly, considering many different factors, such as the heterogeneity of objects and the diversity of communication protocols and enabling technologies. This approach fulfills the IoT vision. This paper surveys the current state of the art of IoT protocols, IPAs in general, and IPAs based on IoTs.
Flexor Tendon Repair Using a Stainless Steel Internal Anchor (1998)

We have developed a stainless steel internal tendon anchor that is used to strengthen a tendon repair. This study tested its use in vitro to produce a repair that can withstand the tensile strength demands of early active flexion. Fresh human cadaver flexor digitorum profundus tendons were harvested, divided, and then repaired using four different techniques: Kessler, Becker or Savage stitches, or the internal tendon anchor. The internal splint repairs demonstrated a 99-270% increase in mean maximal linear tensile strength and a 49-240% increase in mean ultimate tensile strength over the other repairs. It is hoped that this newly developed internal anchor will provide a repair that will be strong enough to allow immediate active range of motion.
Telomerase Regulation, Cell Cycle, and Telomere Stability in Primitive Hematopoietic Cells (1997)

Low levels of telomerase activity have recently been detected in human primitive hematopoietic cells, however, blood cells exhibit telomere shortening on cell proliferation. This challenging observation led us to study telomerase regulation and telomere length in human hematopoietic progenitor cells from fetal liver (FL), cord blood (CB), peripheral blood (PB), and bone marrow (BM). We found telomerase activity in CD34+/CD38+ cells exceeding levels in CD34+/CD38-, CD34- , and mononuclear cells (P < .05). Baseline telomerase activity was highest in BM (n = 5) CD34+ cells, followed by PB (n = 20), CB (n = 11), and FL (n = 1). Within 48 hours to 72 hours of in vitro culture of CD34+ cells in the presence of cytokines (KL, interleukin-3 [IL-3], IL-6, erythropoietin, granulocyte colony-stimulating factor), telomerase activity was upregulated, peaked after 1 week of culture, and decreased to baseline levels or below detection after 3 to 4 weeks. Stimulation of CD34+ cells with single cytokines resulted in no or minor telomerase upregulation, whereas cytokine combinations resulted in a significant telomerase increase (P < .001). There was a correlation between telomerase activity, cell cycle status by BrdU incorporation, and induction of phosphorylated retinoblastoma protein, CDC2, CDK2, cyclin D1, and cyclin A, but not cyclin E and B1 after 72 hours with multiple (but not single) cytokines. In nonexpanding CD34+ cells, telomerase was low or undetectable. Secondary CD34+ cells showed a reduced ability to upregulate telomerase activity. Antiproliferative cytokines such as transforming growth factor-beta1 and high concentrations of all-trans-retinoic acid in cytokine-supported CD34+ cultures downmodulated telomerase activity. Average telomere lengths were 10.4 kbp, 7.4 kbp, and 7.6 kbp in CB, PB, and BM CD34+ cells, respectively. In ex vivo expansion cultures, an average telomeric DNA loss of 1 to 2 kbp over 4 weeks was observed. However, the rate of base pair loss per population doubling was significantly lower during the first 2 weeks, when telomerase was upregulated, than during weeks 3 and 4 of culture. In summary, telomerase is upregulated in response to cytokine-induced proliferation and cell cycle activation in primitive hematopoietic cells. Telomerase is downregulated between weeks 3 and 4 of ex vivo expansion culture linked with decreased proliferation and greater expansion of more mature cell subsets. Our data suggest that telomerase activity in hematopoietic cells reduces, but does not prevent, telomere shortening on proliferation.
