Wi-Fi Direct based Smart Set-up (WDSS) in Lighting Systems (2012)

The Wireless Lighting Control System has drawn intensive attention in the recent years due to the potential for huge cost savings as well as increased convenience. Commonly seen Wireless Lighting Control Systems utilize Zigbee, KNX and Z-WAVE; whereas little attention has been given to Wi-Fi because of unsolved limitations. The purpose of this thesis project was to develop a Wi-Fi Direct based Smart Setup (WDSS) mechanism, in order to make Wi-Fi a proper candidate for the Wireless Lighting Control System. One of the primary limitations of conventional Wi-Fi technology is that the complex setup procedure prevents interface-constrained devices (e.g.lamps) from joining the network. Secondly, the multi-hop Wi-Fi network is not standardized therefore the common Wi-Fi network bears a star topology with only one-hop coverage. The WDSS is an innovative solution, developed on a newly standardized Wi-Fi technology called Wi-Fi Direct, which is being rolled out as standard in Smartphones and other Internet devices. To overcome the first limitation of conventional Wi-Fi technology, WDSS defines a protocol to allow easy commissioning of lamps (and/or other devices) in a Wi-Fi network, adding a major ease of install element to a traditional Wi-Fi based system (without requiring the user interface on lamps). This approach utilizes a third device, namely a commissioning tool, to set up a Wi-Fi Direct link to the lamp, and further instruct the lamp to migrate to an existing Wi-Fi Network in a secured fashion. An additional advantage of the WDSS is that it can also be applied to set up a multi-hop network among lamps. This feature well addresses the second issue, thereby guaranteeing the effective coverage. Unlike many other meshing networks which function in ad-hoc mode, the WDSS multi-hop network is built up in Wi-Fi infrastructure mode, which has been proved to outperform the ad-hoc network in many aspects. The innovation of the WDSS multi-hop network only focuses on the easy setup instead of advanced routing; however, intelligent algorithms and routing methodologies can be compatibly adopted to optimize the traffic flow. As part of this project, a demo has been set up and the WDSS method has been tested on this system. Results showed that the WDSS has significant value in the Wireless Lighting Control System, in terms of easy commissioning, compatibility with standard Wi-Fi infrastructure, applicability on random chipsets, and transparency to the Internet Protocol. The usage of WDSS of course can be easily expanded to other similar applications.
[Simulation of UV spectra from the wake of a stony meteor in the upper atmosphere]. (2005)

For stony meteors thrusting through a region with an altitude between 100-90 km in the upper atmosphere at different initial geocentric velocities, the effective temperatures are calculated based on Sparrow's particle-collision theory. Assuming different mixture ratios, particle number densities of certain dominant components that might exist in the wake of a stony meteor at a velocity of 72 km x s(-1) are given. Using a large-scale spectral synthesis code called Cloudy, UV radiation within the 240-400 nm band of the wake of such a meteor is simulated, and relative intensities of several expected strong emission lines are predicted. Comparison shows that our prediction of the spectrum of a meteor wake, which has an effective temperature of 5 680 K and a fractional vapor pressure of 0.1 Pa, is fairly close to the observational results.
Product Line Engineering Using Domain-Specific Languages (2011)

This paper investigates the application of domain-specific languages in product line engineering (PLE). We start by analyzing the limits of expressivity of feature models. Feature models correspond to context-free grammars without recursion, which prevents the expression of multiple instances and references. We then show how domain-specific languages (DSLs) can serve as a middle ground between feature modeling and programming. They can be used in cases where feature models are too limited, while keeping the separation between problem space and solution space provided by feature models. We then categorize useful combinations between configuration with feature model and construction with DSLs and provide an integration of DSLs into the conceptual framework of PLE. Finally we show how use of a consistent, unified formalism for models, code, and configuration can yield important benefits for managing variability and trace ability. We illustrate the concepts with several examples from industrial case studies.

Optimization of the Deposition Conditions for Epitaxial Silicon Films on Czochralski Sapphire in the Silane‐Hydrogen System (1980)

The deposition of epitaxial silicon films on (012) Czochralski sapphire from the silane/hydrogen system was investigated for growth temperatures from 880° to 980°C and for growth rates from 0.2 to 6.0 μm/min. The film quality was evaluated by optical absorption measurements. The temperature range, in which epitaxial film quality was obtained, shifts with increasing growth rates to higher deposition temperatures. This epitaxial temperature range is rather broad, e.g., 915°–965°C for 0.2–0.5 μm/min and 935°–985°C for 5.3–6.0 μm/min. A region for the optimum epitaxial deposition conditions, very suitable for MOS applications, is defined by the minimum values obtained from the optical absorption measurements. At temperatures below 915°C, decreasing crystalline quality was observed due to an increasing fraction of polycrystalline silicon. In addition the influence of the content on the crystalline quality of the silicon films was investigated; for the production of a good epitaxial silicon film the impurity fraction must be smaller than 1 ppm, especially in the low temperature region.
Two Immunoreactive Binding Proteins for Insulin-Like Growth Factors in Human Amniotic Fluid: Relationship to Fetal Maturity* (1987)

A binding protein for insulin-like growth factors (IGFs) has been purified from human amniotic fluid by IGF-I affinity chromatography and high performance reverse phase chromatography. This protein, with an apparent molecular mass of 28K nonreduced and 34K reduced, had an identical amino-terminus to a previously purified binding protein from amniotic fluid and to placental protein 12. The purified preparation (BP-28) bound both IGFs with high affinity [Ka, 6.55 +/- 2.24 (+/- SD) L/nmol for IGF-I and 3.23 +/- 1.05 L/nmol for IGF-II], with approximately 0.5 mol binding sites/mol BP-28 for either ligand. A 53K IGF-binding protein purified from human plasma (BP-53) did not cross-react in a RIA for BP-28, and BP-28 had less than 0.1% molar cross-reactivity in a RIA for BP-53. Human amniotic fluid reacted strongly in both assays. Fractionation of amniotic fluid samples by reverse phase chromatography showed that BP-28 and BP-53 immunoreactivities were present on separate proteins. In 40 third trimester amniotic fluid samples selected to cover a wide range of lecithin to sphingomyelin ratios, the mean concentrations of BP-28 and BP-53 were 37.6 +/- 17.6 (+/- SD) and 4.6 +/- 1.6 mg/L, respectively. Significant negative correlations were found between the levels of both BP-28 and BP-53 and the lecithin to sphingomyelin ratio, suggesting an association between the levels of both proteins and the degree of fetal maturity. A significant positive association was also found between the levels of BP-28 and BP-53. We conclude that the 28K IGF-binding protein from amniotic fluid, like the previously purified 53K binding protein, has high affinity for both IGF-I and IGF-II, that it coexists in amniotic fluid with BP-53 or a related protein, and that the levels of both proteins decline with increasing fetal maturity.
A New Outlook on the Ideal Packing Theory for Bridging Solids (2012)

Abstract Carefully engineering the size distribution of bridging solids should enable us to form filter cakes of low permeability. A theory called the ideal packing theory is commonly used to blend bridging solids which suggests the ideal blend of particles should follow the relationship cum vol% ∝ dx. The aim of this work was to experimentally assess this theory. Investigations were carried out to determine if there is an x value which gives a better fluid loss performance than the typically-used x = 0.5. The results suggest that selecting x ~ 1 could be more appropriate than using the conventional x = 0.5. The physical meaning when x = 1 is that there will be an equal volume of particles of each size within the distribution; i.e. the distribution is linear. In addition, the results also showed that a blend with a broad size distribution gave a lower fluid loss than a narrow distribution, even when the narrower distribution consisted of finer particles. The trend was that filter cakes of decreasing permeability were formed as x increased from 0.1 to 0.5. Further increase in x up to 1.25 did not appear to have a prominent effect, while further increases beyond 1.25 appeared to increase the filter cake permeability. Trends were similar for filter cakes formed on filter paper and on simulated rock material. Particle blending is important for the selection of bridging solids for drill in fluids, and also for wellbore strengthening (stress cage) applications. Conventional ideal packing theory has been widely used but a review of this theory backed up by laboratory checks has been overdue. This work should aid in the development of a more consistent approach to the selection of the optimum blend of bridging material for a given application.
Electrical conduction properties of n-type Si-doped AlN with high electron mobility (&gt;100cm2V−1s−1) (2004)

For n-type Si-doped AlN, we have obtained an electron mobility and concentration of 125cm2V−1s−1 and 1.75×1015cm−3 at 300K, respectively. At 250K, the mobility reached the maximum of 141cm2V−1s−1. To explain the temperature dependence of the mobility, we calculated mobilities limited by specific scattering mechanisms. We found that the mobility is limited by neutral impurity scattering rather than ionized impurity scattering or lattice scattering because of a large donor ionization energy (∼250meV).

Role of hyperbilirubinemia in the impairment of osteoblast proliferation associated with cholestatic jaundice. (1995)

Because the osteoporosis occurring in chronic cholestatic liver disease (CCLD) is associated with decreased bone formation and is reversible by liver transplantation, substances retained in plasma during cholestasis may impair osteoblast function. This hypothesis was tested using a new bioassay that measures plasma mitogenic activity (PMA) for normal human osteoblast-like (hOB) cells. In 29 jaundiced patients, mean PMA was 56.4% (P < 0.001) of that in 29 age- and sex-matched normal subjects, and the decrease in PMA was similar in the 14 with CCLD and the 15 with other causes of jaundice. Bile acids and bilirubin are the two major groups of products retained during cholestasis. The common conjugated bile acids and bilirubin were added to normal human plasma in concentrations simulating those found in patients with CCLD. Various bile salts had no effect on PMA whereas unconjugated bilirubin decreased PMA in a dose-dependent fashion (r = -0.98, P < 0.0001) without affecting cell viability. Relatively selective removal of bilirubin from the plasma by photobleaching normalized the decreased PMA in five jaundiced patients but produced no apparent change in five normal subjects. These data support the hypothesis that hyperbilirubinemia or possibly other photolabile substances impair osteoblast proliferative capacity and thus may play a major role in the pathogenesis of the osteoporosis associated with CCLD.

Modified pectins in whey protein emulsions (1996)

Abstract In the present work high methoxylic, low methoxylic and amidated pectins were tested for their actions in whey protein emulsions using a broad variation in the emulsion composition (content of protein, pectin, oil) and the solvent conditions (pH, ionic strength). Emulsifying activity index, long term stability and the particle size of the emulsions were determined, protein and galacturonan content of the serum were analysed after centrifugation. A strong relationship was found between emulsion stability and degree of esterification of the pectin, the influence of pectin amidation was relatively low. There were formed stable electrostatic complexes between the protein and the carboxylic groups of the pectin. They seemed to be much more important for emulsion stability than the hydrophobic or hydrogen bonds. The emulsion properties varied in dependence on the content of the single emulsion components and on the solution conditions. All pectins used stabilized the whey protein emulsions if their concentration was high enough. For any individual utilization it is necessary to choose the best suitable pectin.
Operating system management of reconfigurable hardware computing systems (2009)

Reconfigurable computing systems include multiple forms of compute resources. In a multi-tasking system, resources of each type-CPUs and reconfigurable hardware (RH)-must be carefully shared between executing threads to maximize overall system performance. This work examines the inter-dependences between CPU and RH allocation, and how changes to these can affect performance.
Compression of an anomalous single coronary artery from pulmonary artery by banding (2012)

This report describes a case with double outlet right ventricle and doubly committed ventricular septal defect associated with congenital diaphragmatic hernia. The patient underwent pulmonary artery banding and clipping of patent ductus arteriosus after repair of the diaphragmatic hernia. At 6 months, cardiac catheterization revealed anomalous origin of a single coronary artery from the pulmonary artery of the proximal banding. Although ischaemic symptoms had not been observed, the banding had resulted in compression of the coronary ostium. An emergency Rastelli procedure with Damus-Kaye-Stansel anastomosis was successfully performed.
A flow cytometry technique to study intracellular signals NF-κB and STAT3 in peripheral blood mononuclear cells (2007)

Cytokines have essential roles on intercellular communications and are effective in using a variety of intracellular pathways. Among this multitude of signalling pathways, the NF-κB (nuclear factor kappaB) and STAT (signal transducer and activator of transcription) families are among the most frequently investigated because of their importance. Indeed, they have important role in innate and adaptive immunity. Current techniques to study NF-κB and STAT rely on specific ELISAs, Western Blots and – most recently described – flow cytometry; so far, investigation of such signalling pathways are most commonly performed on homogeneous cells after purification. The present investigation aimed at developing a flow cytometry technique to study transcription factors in various cellular types such as mixtures of B-cells, T-lymphocytes and monocytes/macrophages stimulated in steady state conditions (in other words, as peripheral blood mononuclear cells). To achieve this goal, a two step procedure was carried out; the first one consisted of stimulating PBMCs with IL1β, sCD40L and/or IL10 in such a manner that optimal stimulus was found for each cell subset (and subsequent signal transduction, therefore screened by specific ELISA); the second step consisted of assessing confirmation and fine delineation of technical conditions by specific Western-Blotting for either NF-κB or STAT products. We then went on to sensitize the detection technique for mixed cells using 4 color flow cytometry. In response to IL1β, or IL10, the levels of phosphorylated NF-κB and STAT3 – respectively – increased significantly for all the studied cell types. In contrast, B-cells and monocytes/macrophages – but, interestingly, not T-lymphocytes (in the context of PBMCs) – responded significantly to sCD40L by increasing phosphorylated NF-κB.
The Tyrosine Phosphatase STEP Mediates AMPA Receptor Endocytosis after Metabotropic Glutamate Receptor Stimulation (2008)

Although it is well established that AMPA receptor (AMPAR) trafficking is a central event in several forms of synaptic plasticity, the mechanisms that regulate the surface expression of AMPARs are poorly understood. Previous work has shown that striatal-enriched protein tyrosine phosphatase (STEP) mediates NMDAR endocytosis. This protein tyrosine phosphatase is enriched in the synapses of the striatum, hippocampus, cerebral cortex, and other brain regions. In the present investigation, we have explored whether STEP also regulates AMPAR internalization. We found that (RS)-3,5-dihydroxyphenylglycine (DHPG) stimulation triggered a dose-dependent increase in STEP translation in hippocampal slices and synaptoneurosomes, a process that requires stimulation of mGluR5 (metabotropic glutamate receptor 5) and activation of mitogen-activated protein kinases and phosphoinositide-3 kinase pathways. DHPG-induced AMPAR internalization and tyrosine dephosphorylation of GluR2 (glutamate receptor 2) was blocked by a substrate-trapping TAT-STEP [C/S] protein in hippocampal slices and cultures. Moreover, DHPG-triggered AMPAR internalization was abolished in STEP knock-out mice and restored after replacement of wild-type STEP. These results suggest a role for STEP in the regulation of AMPAR trafficking.
Zero quiescent current, delay adjustable, power-on-reset circuit (2014)

A power-on-reset (POR) circuit is extremely important in digital and mixed-signal ICs. It is used to initialize critical nodes of digital circuitry inside the chip during power-on. A novel POR circuit having zero quiescent current and an adjustable delay is proposed and demonstrated. The circuit has been designed in 0.5μm CMOS process to work for a supply voltage ranging from 1.8V to 5.5V. The circuit generates a POR signal after a predetermined delay, after the supply voltage crosses a predefined threshold voltage. This delay can be increased or decreased via programmable fuses. The POR threshold does not depend upon the supply ramp rate. The Brown-Out (BO) voltage for the proposed circuit matches the minimum supply voltage required by the digital circuitry inside the IC. The circuit consumes zero steady state current, making it ideal for low power applications.
A cell-free extract from human adipose stem cells protects mice against epilepsy (2011)

Our results demonstrate that human ASCs-E prevents or inhibits epileptogenesis and SRS in mice. They also suggest a stem cell-based, noninvasive therapy for the treatment of epilepsy.
Estimation of von Liebig Response Functions (1989)

Abstract Two distinct but related approaches for the estimation of von Liebig response functions are presented. The first approach is based upon a two‐phase, ordinary least squares procedure combined with bootstrapping for computing the standard errors of the estimates. The second approach generates maximum likelihood estimates of the parameters and can be implemented according to two different parameterizations of the model. Application of the procedures to a sample of experimental data suggests a satisfactory degree of conformity of the results. A test of normality of the disturbance term based upon the estimated residuals failed to reject the null hypothesis, further supporting the maximum likelihood approach.
Acute graft-versus-host disease after unrelated donor umbilical cord blood transplantation: analysis of risk factors (2008)

Acute graft-versus-host disease (GVHD) occurs less frequently after umbilical cord blood transplantation (UCBT). More recent investigations include the use of 2 partially human leukocyte antigen (HLA)-matched UCB units, or double UCB graft, to meet the minimum cell-dose requirement. The purpose of this analysis was to assess the relative risk of acute GVHD in 265 consecutive patients receiving transplants with UCB graft composed of 1 (n = 80) or 2 (n = 185) units. The incidence of grade III-IV acute GVHD was similar between cohorts. However, the incidence of grade II-IV acute GVHD was higher among double UCBT recipients (58 vs 39%, P < .01). Three risk factors for grade II-IV acute GVHD were identified in multiple regression analysis: use of 2 UCB units, use of nonmyeloablative conditioning, and absence of antithymocyte globulin in the conditioning regimen. Transplantation-related mortality (TRM) at 1 year, however, was significantly lower after double UCBT (24 vs 39%, P = .02) even if recipients had grade II-IV acute GVHD (20 vs 39%, P = .05). These data suggest that, despite a higher incidence of grade II acute GVHD in recipients of 2 partially HLA-matched UCB units, there is no adverse effect on TRM. This study is registered at (http://www.clinicaltrials.gov) under the identifiers NCT00305682 and NCT00309842.
Hops-based Sleep Scheduling Algorithm for Enhancing Lifetime of Wireless Sensor Networks (2006)

In this paper, we study the node sleep scheduling scheme in the commonly used static disk model for sensor networks, where homogenous sensors are uniformly distributed in a circular area with a stationary sink located at the center. Then, we introduce and analyze a hops-based sleeping scheduling algorithm (HSS) for enhancing the lifetime and energy efficiency of the sensor networks. The HSS divides the circular sensor network into several levels according to the average hop distance based on certain network parameters. By assigning hops-based sleeping probabilities to each sensor, and the network lifetime as well as energy efficiency can be greatly improved. Simulations are performed to compare our proposed HSS scheme with the traditional randomized sleeping scheduling (RSS) scheme, where all the nodes have the uniform sleeping probability. The results demonstrate that our HSS scheme can enhance network lifetime greatly, provide desired QoS requirement effectively, and drastically outperform the RSS scheme
