Development of a photonic integrated transceiver chip for WDM transmission (1994)

With the observed expansion of fiber-optic networks and the movement of line terminals towards the individual customer the need for cost-effective fabrication of customer access modules for interactive services arises. Monolithic integration of the module functions on InP is frequently seen as a means to reduce module costs. Here we describe a generic fabrication process for InP photonic integrated circuits and demonstrate an initial transceiver chip with transmit, receive and 1300/1530 nm wavelength division multiplexing functions. The chip output power reaches 1 mW at 1530 nm with a laser threshold current of 20 mA. The detection efficiency at 1300 nm is 0.1 A/W of fiber power.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Strongly green-photoluminescent graphene quantum dots for bioimaging applications (2011)

Strongly fluorescent graphene quantum dots (GQDs) have been prepared by one-step solvothermal method with PL quantum yield as high as 11.4%. The GQDs have high stability and can be dissolved in most polar solvents. Because of fine biocompatibility and low toxicity, GQDs are demonstrated to be excellent bioimaging agents.

The Role and Implementation of Compliance in Legged Locomotion (2008)

Many robots excel at precise positioning and trajectory tracking using software control, and most successful robotic applications utilize this ability—examples include CNC machining, robotic welding, painting, and pick-and-place circuit board assembly. The mechanical design of these robots focuses on rigid transmissions and minimizing compliance in the structure, so the software controller can accurately track a desired position as a function of time, regardless of any disturbance forces. However, there is a class of tasks for which rigid actuation is not ideal: physical interaction with the world, especially interaction that involves an impact or kinetic energy transfer. Animals tend to excel at these tasks, and far outperform the best robots. Examples include walking, running, catching a ball, gripping a piece of fruit firmly but without causing damage, and many types of assembly tasks. For dynamic behaviors such as running, the performance limitations of a robot are often due to limitations of the mechanical design. A robot is an integrated system of electronics, software, and mechanism, and each part of the system limits or enables the behavior of the whole. While some behaviors can easily be implemented through simple actuators and direct software control, a running machine requires mechanical design that is specialized for the task. Among other things,
The carboxyl-terminal cytoplasmic domain of CD36 is required for oxidized low-density lipoprotein modulation of NF-kappaB activity by tumor necrosis factor-alpha. (1997)

The binding of oxidized low-density lipoprotein (Ox LDL) by monocyte-macrophages causes pleiotropic effects, including changes in gene expression, and is thought to represent an early event in atherogenesis. The integral membrane glycoprotein CD36 appears to play a physiological role in binding and uptake of Ox LDL by monocyte-macrophages, although the molecular events associated with CD36-Ox LDL interaction are unknown. To approach this issue, we used CD36 transfected Chinese hampster ovary (CHO) cells, exposed them to Ox LDL, and determined changes in the activity of the transcription factor NF-kappaB. We report here that Ox LDL enhanced DNA binding activity of nuclear extracts to an NF-kappaB sequence following activation of CD36-producing CHO cells with the proinflammatory cytokine tumor necrosis factor-alpha (TNF-alpha). This enhanced DNA binding activity was inhibited by coincubation of CD36 transfected cells with the human CD36-specific antibody OKM5. We also determined that activation of NF-kappaB DNA binding activity required an intact carboxyl-terminal cytoplasmic segment on CD36. Our results support the idea that human CD36 mediates signal transduction events in response to Ox LDL.
Fixation of copper(II)-protein formulation in wood: Part 1. Influence of tannic acid on fixation of copper in wood (2008)

Abstract A new waterborne CuSO 4 ·5 H 2 O-based formulation containing proteins from animal plasma SOLUTEIN (0.1%) as additive was investigated. Scots pine sapwood powder, cellulose and lignin were impregnated with solutions containing 0.1% and 2.5% copper (w/v). After impregnation, the samples were additionally treated by air-drying at 100°C or by tannic acid for denaturation of the proteins. Copper concentration was determined by atomic absorption spectroscopy and electron paramagnetic resonance (EPR). Copper introduced into wood by impregnation and eliminated by leaching was controlled. The maximum retention of 5.83 g kg -1 in wood was obtained when wood was treated with tannic acid (2.5%) after impregnation. For a formulation containing more than 0.5% of CuSO·5 H 2 O, precipitation of the salt in wood appears. Five different EPR spectra appeared in wood, cellulose and lignin after treating with SOLUTEIN and with tannic acid.
A Rotary Travelling Wave Oscillator Based All-Digital PLL in 65nm CMOS (2017)

This thesis presents the design and implementation of an All-Digital Phase Locked Loop (ADPLL) that uses Delta-Sigma () modulation, multi-phase outputs, and Dynamic Element Matching (DEM). The system is designed using a combination of 65nm CMOS technology and an FPGA. The frequency range of the ADPLL output is 5.48GHz to 6.22GHz. Several design techniques are used to reduce the phase noise of the ADPLL output. The ADPLL uses a rotary travelling wave-based Digitally Controlled Oscillator (DCO) with multi-phase outputs to improve quantization noise. Manufacturing variations on the fine-tuning DCO input capacitors are averaged using DEM to produce more uniform frequency steps. modulation is used on the least significant of the DCO input bits. This modulation introduces a dithering effect on the output frequency that has the effect of moving some of the phase noise away from the ADPLL carrier frequency.
A SEPIC fed buck converter (2012)

A new patented topology - the SEPIC fed buck converter [1, 2] - addresses two critical issues confronting the power electronics field today: efficiency and transient response. A buck converter is integrated into a SEPIC to receive energy from the SEPIC inductors and the outputs of both deliver energy to the load in parallel. When the controlling switch - shared by both converters - is ON, the buck portion delivers energy to the load while the SEPIC portion stores energy in the magnetic element and feeds the buck portion. When the controlling switch is OFF, the stored energy is delivered to the load through both the buck and the SEPIC portions. The new converter has a voltage transfer ratio E <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">OUT</sub> /E <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">IN</sub> = D/(2 - D) of and complementarily combines the characteristics of both buck and SEPIC converters, resulting in reduced voltage and current levels in the magnetic and switching devices and leading to reduced conduction and switching losses. Additionally, an inherent gate-charge-extraction mechanism facilitates extremely fast turn-off of the control switch, essentially eliminating its turn-off loss. Furthermore, a new volt-second structure on the magnetic element significantly improves transient response of the power stage.
Orienting the Neighborhood: A Subdivision Energy Analysis Tool; Preprint (2008)

In addition to the main indications pertaining to 95 % of all patients receiving liver transplantation in Germany, there are numerous other diseases that may become clinically evident in the adult age and may lead to the decision for liver transplantation. These may be metabolic diseases with their main defect located in the liver, malformations of liver cells, hepatic vascular diseases and rare tumours of the liver. Standard exceptions for the listing are in place only for a limited number of diseases. Exact diagnostics and the point in time for transplantation are crucial for the prognosis.
Mixed Uses and the Redevelopment Option (1996)

This paper considers how the potential for mixing uses and redevelopment impact property value. Operating flexibility of this type is found to significantly increase property value when the correlation between payouts from different property types is low or when redevelopment costs are low. The ability to mix uses and redevelop over time is also shown to affect the timing of initial land development. The shape of the development boundary is shown to differ considerably depending on whether marginal revenue is constant or decreasing to scale. Both policy and empirical implications concerning the effects of multiple‐use zoning are discussed.
Intraventricular sodium nitroprusside therapy: a future promise for refractory subarachnoid hemorrhage-induced vasospasm. (2003)

A prospective study was carried out to evaluate the efficacy of intraventricular sodium nitroprousside (SNP) in the reversal of refractory vasospasm secondary to aneurysmal subarachnoid hemorrhage (SAH). Ten patients of aneurysmal SAH with symptomatic vasospasm, corroborated on Transcranial Doppler (TCD) and/or angiography, were included in the study. The mean age distribution of the patients was 50.8 years (range 33-65 years) with an equal number of males and females. Once vasospasm was refractory even after 12 hours of SAH therapy, intraventricular SNP was instilled in an escalating dose and the reversal of vasospasm was monitored on TCD and/or angiography. All patients showed improvement in TCD velocity on day 0 through day 3. Partial to complete reversal of vasospasm was demonstrated on angiography in all the patients, though not in all the vessels. Two patients who had weakness of limbs due to vasospasm improved following intraventricular SNP therapy. Vomiting was the commonest adverse effect (7/10). Three patients had mild fluctuation in blood pressure. The overall outcome was good in 6 out of 10 patients. The study suggests that intraventricular SNP therapy is effective in reversing the changes even in established cases of SAH-induced vasospasm.

Human Islet Amyloid Polypeptide Oligomers Disrupt Cell Coupling, Induce Apoptosis, and Impair Insulin Secretion in Isolated Human Islets (2006)

Insulin secretion from the 2,000-3,000 beta-cells in an islet is a highly synchronized activity with discharge of insulin in coordinate secretory bursts at approximately 4-min intervals. Insulin secretion progressively declines in type 2 diabetes and following islet transplantation. Both are characterized by the presence of islet amyloid derived from islet amyloid polypeptide (IAPP). In the present studies, we examined the action of extracellular human IAPP (h-IAPP) on morphology and function of human islets. Because oligomers of h-IAPP are known to cause membrane disruption, we questioned if application of h-IAPP oligomers to human islets would lead to disruption of islet architecture (specifically cell-to-cell adherence) and a decrease in coordinate function (e.g., increased entropy of insulin secretion and diminished coordinate secretory bursts). Both hypotheses are affirmed, leading to a novel hypothesis for impaired insulin secretion in type 2 diabetes and following islet transplantation, specifically disrupted cell-to-cell adherence in islets through the actions of membrane-disrupting IAPP oligomers.
EcID. A database for the inference of functional interactions in E. coli (2008)

The EcID database (Escherichia coli Interaction Database) provides a framework for the integration of information on functional interactions extracted from the following sources: EcoCyc (metabolic pathways, protein complexes and regulatory information), KEGG (metabolic pathways), MINT and IntAct (protein interactions). It also includes information on protein complexes from the two E. coli high-throughput pull-down experiments and potential interactions extracted from the literature using the web services associated to the iHOP text-mining system. Additionally, EcID incorporates results of various prediction methods, including two protein interaction prediction methods based on genomic information (Phylogenetic Profiles and Gene Neighbourhoods) and three methods based on the analysis of co-evolution (Mirror Tree, In Silico 2 Hybrid and Context Mirror). EcID associates to each prediction a specifically developed confidence score. The two main features that make EcID different from other systems are the combination of co-evolution-based predictions with the experimental data, and the introduction of E. coli-specific information, such as gene regulation information from EcoCyc. The possibilities offered by the combination of the EcID database information are illustrated with a prediction of potential functions for a group of poorly characterized genes related to yeaG. EcID is available online at http://ecid.bioinfo.cnio.es.
Strategies for Lipid Production Improvement in Microalgae as a Biodiesel Feedstock (2016)

In response to the energy crisis, global warming, and climate changes, microalgae have received a great deal of attention as a biofuel feedstock. Due to a high lipid content in microalgal cells, microalgae present as a promising alternative source for the production of biodiesel. Environmental and culturing condition variations can alter lipid production as well as chemical compositions of microalgae. Therefore, application of the strategies to activate lipid accumulation opens the door for lipid overproduction in microalgae. Until now, many original studies regarding the approaches for enhanced microalgal lipid production have been reported in an effort to push forward the production of microalgal biodiesel. However, the current literature demonstrates fragmented information available regarding the strategies for lipid production improvement. From the systematic point of view, the review highlights the main approaches for microalgal lipid accumulation induction to expedite the application of microalgal biodiesel as an alternative to fossil diesel for sustainable environment. Of the several strategies discussed, the one that is most commonly applied is the design of nutrient (e.g., nitrogen, phosphorus, and sulfur) starvation or limitation. Other viable approaches such as light intensity, temperature, carbon dioxide, salinity stress, and metal influence can also achieve enhanced microalgal lipid production.
Public Procurement Reform in Morocco (2014)

Over the last decade Morocco has made important strides in responding to citizen demands for more transparency, accountability, and shared prosperity. This has also extended into the public sector and its varied functions. In Morocco public contracts account for some 17 percent of GDP and are responsible for critical activities in the economy, including delivery of key public services.2 Given its important role, the Government of Morocco (GoM) prioritized public procurement for comprehensive reforms. Starting with 2003 Country Procurement Assessment Report (CPAR) Morocco embarked on a productive dialogue with the World Bank to improve its procurement system and optimize the performance of its public investments.
Design Automation for Continuous-Flow Microfluidic Biochips (2017)

Continuous-flow microfluidics has evolved very rapidly in the last twenty years. Biochemical applications can be performed in parallel and automatically on continuous-flow microfluidic chips, by which more precise results with higher throughput can be achieved. To date, most continuous-flow microfluidics are still designed manually, which is time-consuming, error-prone, and especially impractical for large-scale-integration. Design automation researchers started to develop design automation tools for continuous-flow microfluidics about ten years ago. Some of these are front-end tools, which scheduled biological operations from assay protocols and allocated these operations to microfluidic devices. Some others are back-end tools, which performed automatic device placement and micro-channel routing. As new on-chip components, e.g., sieve valves, and new architectures, e.g., a homogeneous valve-centered architecture, are continuously invented and adopted, design automation tools also evolve accordingly over time. This dissertation first provides a brief review of design automation research for continuous-flow microfluidics over the last decade. In this review, a detailed description is given for the microfluidic architecture and the general topics of front-end as well as back-end research in design automation field. Selected research results are then introduced according to their appearance over time, which also matches the general trend of research topics from front-end to back-end. The main body of the dissertation presents new research results that cover four topics in four chapters: temporary caching of fluids, sieve valve exploration, synthesis for reconfigurable chips, and the layout generation tool Columba.
Ion Binding Properties of the Dehydrin ERD14 Are Dependent upon Phosphorylation (2003)

The ERD14 protein (early response to dehydration) is a member of the dehydrin family of proteins which accumulate in response to dehydration-related environmental stresses. Here we show the Arabidopsis dehydrin, ERD14, possesses ion binding properties. ERD14 is an in vitro substrate of casein kinase II; the phosphorylation resulting both in a shift in apparent molecular mass on SDS-PAGE gels and increased calcium binding activity. The phosphorylated protein bound significantly more calcium than the nonphosphorylated protein, with a dissociation constant of 120 microm and 2.86 mol of calcium bound per mol of protein. ERD14 is phosphorylated by extracts of cold-treated tissues, suggesting that the phosphorylation status of this protein might be modulated by cold-regulated kinases or phosphatases. Calcium binding properties of ERD14 purified from Arabidopsis extracts were comparable with phosphorylated Escherichia coli-expressed ERD14. Approximately 2 mol of phosphate were incorporated per mol of ERD14, indicating a minimum of two phosphorylation sites. Western blot analyses confirmed that threonine and serine are possible phosphorylation sites on ERD14. Utilizing matrix assisted laser desorption ionization-time of flight/mass spectrometry we identified five phosphorylated peptides that were present in both in vivo and in vitro phosphorylated ERD14. Our results suggest that the polyserine (S) domain is most likely the site of phosphorylation in ERD14 responsible for the activation of calcium binding.
A Spiral Microwave Directional Coupler for MIC Application (1980)

Formation of Pyro-products by the Pyrolysis of Monobromophenols (2003)

Thermal behavior of bromphenols was investigated by direct pyrolysis at high temperature. The thermal degradation products formed by the pyrolysis of mono-bromophenols (o-, m-, and p-) were identified by gas chromatography-mass spectrometry. During the pyrolysis reactions, several kinds of dioxins and furans were produced, and the relative ratio of pyro-products was dependent on the substituted position of bromine in phenolic structure due to the effect of symmetry and steric hindrance. The formation of dioxins can be explained by the phenoxy radical addition and Br atom elimination at an ortho-carbon site on phenolic structure. On the other hand, the formation of furans can be explained by the ortho-ortho carbon coupling of phenoxy radicals at unsubstituted sites to form o, o'-dihydroxydiphenyl intermediate via its keto-tautomer, followed by <TEX>$H_2O$</TEX> elimination. The pyrolysis temperature has also a substantial effect on the dimerized products quantities but little effect on the type of pyro-products. Moreover, the formation mechanism of pyro-products was suggested on the basis of products identified.
Capping layers for extreme-ultraviolet multilayer interference coatings (2001)

The reflectivity of extreme-ultraviolet thin-film multilayer (ML) interference coatings, terminated by a native oxide or other capping layer (CL), is critically dependent on the thickness of the final deposited layer of the top period. We show in this numerical study that, for a molybdenum-silicon ML, a high reflectivity loss may be incurred if the final Si layer is not of optimum thickness. For maximum reflectivity the thickness of the final Si layer must be controlled such that the node of the standing wave lies within the absorptive CL.The final Si layer may be replaced, at the expense of reflectivity, by SiC and capped with another inert material for improved protection of the ML.

Refinements to the theory of error rates for narrow-band digital FM (1988)

The bit-error-rate performance of narrowband digital FM with limiter-discriminator detection is considered for the cases of integrate and dump postdetection filtering with partial-bit integration, and sample-and-hold bit detection at the discriminator output. Error rate curves are presented for Gaussian, six-element Butterworth, and two-stage synchronously tuned IF filters. The calculations illustrate just how much more E/sub b//N/sub 0/ is required as the partial-bit integration time goes from 100% down to the limiting case of sample and hold. The results show that it is important to have a well-designed IF filter especially if the entire bit time is not available for detection.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
