On the provision of quality-of-service guarantees for input queued switches (2000)

While the Internet has quietly served as a research and education vehicle for more than two decades, the last few years have witnessed its tremendous growth and its great potential for providing a wide variety of services. As a result, input-queued switching architectures, because of their distinguished advantage in building scalable switches, are currently receiving a lot of attention from both academia and industry as an attractive alternative for developing future-generation ATM/IP switches/routers. However, the problem of designing scheduling algorithms with QoS guarantees for input-queued switches has always been known to be a very challenging problem. We give an overview of the efforts in designing scheduling algorithms capable of providing QoS guarantees for input-queued switches. These algorithms are classified under three categories: those based on slot time assignment, those based on maximal matching, and those based on stable matching. We also present some open problems on this topic as future research directions in this area.
Flexible notification for collaborative systems (2002)

Notification is an essential feature in collaborative systems, which determines a system's capability and flexibility in supporting different kinds of collaborative work. In the past years, various notification strategies have been designed for different systems. However, the design of notification components has been ad hoc, and the techniques used for supporting notification have been application-dependent. In this paper, we contribute a flexible notification framework that can be used to describe and compare a range of notification strategies used in existing collaborative systems, and to guide the design of notification components for new collaborative systems. The framework has been applied to the design of a notification component for a group editor, which uses a single notification mechanism to support various notification policies for meeting both real-time and non-real-time collaboration needs. In addition, a new operational transformation control algorithm has been devised in combination with the notification component, which is significantly simpler and more efficient than existing algorithms.
A microfluidic system to study cytoadhesion of Plasmodium falciparum infected erythrocytes to primary brain microvascularendothelial cells (2011)

The cellular events leading to severe and complicated malaria in some Plasmodium falciparum infections are poorly understood. Additional tools are required to better understand the pathogenesis of this disease. In this technical report, we describe a microfluidic culture system and image processing algorithms that were developed to observe cytoadhesion interactions of P. falciparum parasitized erythrocytes rolling on primary brain microvascularendothelial cells. We isolated and cultured human primary microvascular brain endothelial cells in a closed loop microfluidic culture system where a peristaltic pump and media reservoirs were integrated onto a microscope stage insert. We developed image processing methods to enhance contrast of rolling parasitized erythrocytes on endothelial cells and to estimate the local wall shear stress. The velocity of parasitized erythrocytes rolling on primary brain microvascularendothelial cells was then measured under physiologically relevant wall shear stresses. Finally, we deployed this method successfully at a field site in Blantyre, Malawi. The method is a promising new tool for the investigation of the pathogenesis of severe malaria.
Measurement‐Based Interactive Simulation of Viscoelastic Solids (2004)

Abstract Animation of viscoelastic solids in entertainment and medical applications as well as scientific simulation can be improved through observations of real world objects. This paper presents a method for simulating viscoelastic solids in real‐time for visual and haptic display along with a method for determining the parameters of the the underlying model from automated physical measurements of real world objects. The viscoelastic model is a novel extension of the discrete Green's function matrix for linear elasticity, which combines static behavior represented by Green's functions with dynamic behavior expressed by differential equations inspired by particle systems. We describe a novel estimation method of dynamic contact behavior for heterogeneous complex objects based on these measurements. For this estimation, our method relies only on measurement data previously used in the acquisition less realistic elastostatic models. In this way our method allows more physically accurate realism in animation of viscoelastic solids without large additional computational costs or any measurements besides those associated with related methods for elastostatic solids.

Investigation of the combustion characteristics of fuel droplet arrays. Final technical report (1980)

The program was directed at establishing the nature and extent of droplet/droplet interaction and the multicomponent nature of real fuels on the ignition and combustion characteristics of spray flames. A unique free-droplet combustion experiment provided the present investigation with a well-controlled simulation of spray combustion. Various theoretical models were used. Experimental observations indicate that ignition delay times increase sharply by about three-fold when droplet spacings are reduced to less than five droplet diameters. Results of theoretical predictions indicate that as droplet spacing is made smaller, the effect of droplet/droplet interaction on ignition delay becomes increasingly more pronounced for small droplets, low gas phase temperatures, and fuels of low volatility. Although this result suggests that ignition of heavy grades of alternative liquid fuels will be inhibited in dense sprays, other theoretical and experimental results indicate that the addition of a small quantity of a volatile component to a heavy fuel shortens ignition times substantially. Observed burning times show a gradual, but substantial, increase as a result of droplet/droplet interaction; as droplet spacing is decreased from 40 to 5 diameters, burning times increase by about 60%. A compilation of data for an extensive range of experimental parameters show universally that the amount by which droplet/droplet interaction increases burning times depends only on droplet spacing and not on the fuel type or the ambient conditions. Burning times of multicomponent fuel droplets are found to be weighted heavily toward the burning time for the least volatile component. Theoretical predictions demonstrate that this independence of burning times on the initial fuel mixture proportions can be ascribed to liquid phase mass diffusion limitations.
A Comparison of Brachial, Femoral, and Aortic Intra-Arterial Pressures before and after Cardiopulmonary Bypass (1989)

Following recent evidence that brachial and femoral artery pressures are more reliable than radial artery pressures after cardiopulmonary bypass, thirty-one adults had simultaneous pre- and post-bypass measurements of brachial, femoral, and ascending aortic pressures. Two minutes after cardiopulmonary bypass, brachial artery systolic pressure and mean arterial pressure fell significantly below corresponding pressures in the femoral artery and aorta. Five minutes after cardiopulmonary bypass, only brachial artery systolic pressure was still less than femoral and aortic systolic pressures. By ten minutes after bypass, all significant pressure differences had resolved except between brachial and femoral artery systolic pressures. Clinically significant (greater than or equal to 5 mmHg) aortic-to-brachial reductions in mean arterial pressures occurred in six (19%) patients at two minutes and in three (10%) patients at five and ten minutes after bypass. Equivalent aortic-to-femoral mean pressure diminution occurred in two (6%) patients at two minutes and one (3%) patient at five and ten minutes after bypass. Neither systemic vascular resistance nor body temperatures contributed significantly to post-bypass central-to-peripheral pressure reductions. Immediately following bypass, femoral artery pressures reproduce central aortic pressures more reliably than do radial or brachial artery pressures.
Two-dimensional gel electrophoresis of cerebrospinal fluid proteins. (1980)

Two-dimensional electrophoresis, with isoelectric focusing in the first dimension and sodium dodecyl sulfate/polyacrylamide gel electrophoresis in the second, has been adapted for the high-resolution analysis of cerebrospinal fluid proteins. Proteins were detected with a new, highly sensitive silver stain that made visible more than 300 polypeptides from 60 microL of spinal fluid, in highly reproducible patterns. We have mapped these patterns, noting difference between the proteins observed in spinal fluid and plasma, and have prepared a partial map of cerebrospinal fluid proteins.
Effects of subacute ingestion of chlorogenic acids on sleep architecture and energy metabolism through activity of the autonomic nervous system: a randomised, placebo-controlled, double-blinded cross-over trial (2017)

Chlorogenic acids (CGA) are the most abundant polyphenols in coffee. Continuous consumption of CGA reduces body fat and body weight. Since energy metabolism and sleep are controlled by common regulatory factors, consumption of CGA might modulate sleep. Lack of sleep has been identified as a risk factor for obesity, hypertension and type 2 diabetes. The aim of this study was to determine the effects of ingesting CGA over 5 d on energy metabolism and sleep quality in humans. A total of nine healthy subjects (four male and five female) completed a placebo-controlled, double-blinded, cross-over intervention study. Subjects consumed a test beverage containing 0 or 600 mg of CGA for 5 d. On the fifth night, subjects stayed in a whole-room metabolic chamber to measure energy metabolism; sleep was evaluated using polysomnographic recording. It was found that CGA shortened sleep latency (9 (sem 2) v. 16 (sem 4) min, P<0·05) compared with the control, whereas no effect on sleep architecture, such as slow-wave sleep, rapid eye movement or waking after sleep onset, was observed. Indirect calorimetry revealed that consumption of CGA increased fat oxidation (510 (sem 84) kJ/8 h (122 (sem 20) kcal/8 h) v. 331 (sem 79) kJ/8 h (81 (sem 19) kcal/8 h), P<0·05) but did not affect energy expenditure during sleep. Consumption of CGA enhanced parasympathetic activity assessed from heart-rate variability during sleep (999 (sem 77) v. 919 (sem 54), P<0·05). A period of 5-d CGA consumption significantly increased fat oxidation during sleep, suggesting that beverages containing CGA may be beneficial to reduce body fat and prevent obesity. Consumption of CGA shortened sleep latency and did not adversely affect sleep quality.

A Global Transcriptional Regulator in Thermococcus kodakaraensis Controls the Expression Levels of Both Glycolytic and Gluconeogenic Enzyme-encoding Genes (2007)

We identified a novel regulator, Thermococcales glycolytic regulator (Tgr), functioning as both an activator and a repressor of transcription in the hyperthermophilic archaeon Thermococcus kodakaraensis KOD1. Tgr (TK1769) displays similarity (28% identical) to Pyrococcus furiosus TrmB (PF1743), a transcriptional repressor regulating the trehalose/maltose ATP-binding cassette transporter genes, but is more closely related (67%) to a TrmB paralog in P. furiosus (PF0124). Growth of a tgr disruption strain (Deltatgr) displayed a significant decrease in growth rate under gluconeogenic conditions compared with the wild-type strain, whereas comparable growth rates were observed under glycolytic conditions. A whole genome microarray analysis revealed that transcript levels of almost all genes related to glycolysis and maltodextrin metabolism were at relatively high levels in the Deltatgr mutant even under gluconeogenic conditions. The Deltatgr mutant also displayed defects in the transcriptional activation of gluconeogenic genes under these conditions, indicating that Tgr functions as both an activator and a repressor. Genes regulated by Tgr contain a previously identified sequence motif, the Thermococcales glycolytic motif (TGM). The TGM was positioned upstream of the Transcription factor B-responsive element (BRE)/TATA sequence in gluconeogenic promoters and downstream of it in glycolytic promoters. Electrophoretic mobility shift assay indicated that recombinant Tgr protein specifically binds to promoter regions containing a TGM. Tgr was released from the DNA when maltotriose was added, suggesting that this sugar is most likely the physiological effector. Our results strongly suggest that Tgr is a global transcriptional regulator that simultaneously controls, in response to sugar availability, both glycolytic and gluconeogenic metabolism in T. kodakaraensis via its direct binding to the TGM.
‘Focused’ assembly of V<sub>2</sub>O<sub>5</sub> nanowire masks for the fabrication of metallic nanowire sensors (2007)

We present a method to overcome the resolution limit of the conventional directed-assembly strategy and to mass-produce metallic nanowire-based devices. In this method, 'microscale' self-assembled monolayer patterns with 'gradient' surface molecular density 'focused' the assembly of vanadium oxide nanowires onto the 'nanoscale' regions on a metallic thin film. Then, the assembled nanowires were utilized as a shadow mask to generate metallic nanowire-based devices. As a proof of concept, we successfully demonstrate the fabrication of metallic nanowire-based highly-selective sensors to detect thiol molecular solution or hydrogen gas under ambient conditions. This approach provides us with an easy, but efficient, means to generate metallic nanowire-based devices over a large surface area for various practical applications such as chemical sensors and nanoscale interconnectors.
Optical classification of bruises (2004)

This thesis covers a wide field of applications, with an emphasis on applications of reflectance spectroscopy for diagnostic purposes. Reflectance spectroscopy in the visible part of the spectrum has been proved to be a valuable tool in a variety of applications including e. g. port-wine stain diagnostics, diagnostics of liver pathology, neonatal jaundice and age determination of bruises for forensic applications.
Cellular volume and marker expression in human peripheral blood apheresis stem cells (2008)

Coulter volume is far more accurate measure of cell volume than forward angle light scatter. In this report, we have used Coulter volume to determine the mean cell volume and diameter of normal human peripheral blood cells and hematopoietic progenitor cells obtained by apheresis (HPC-A) from patients with hematological malignancies. Fresh peripheral blood samples (treated with Beckman Coulter IMMUNOPrep erythrocyte lysis solution), HPC-A samples (treated with BD Biosciences FACSLysing solution), or processed by Ficoll Hypaque sedimentation method were stained with CD45-FITC and PE-labeled CD34, CD90, CD117, and CD133 antibodies and analyzed for electronic volume and two color fluorescence. The mean electronic volume and diameter of mononuclear cells from fresh peripheral blood samples prepared with IMMUNOPrep were lymphocytes (191 microm(3), 7.16 microm), monocytes (370 microm(3), 9.91 microm), and granulocytes (328 microm(3), 8.56 microm). In mononuclear cells of HPC-A samples prepared by Histopaque-1077 sedimentation, the lymphocytes had volume and diameter of 311 microm(3), 8.4 microm, monocytes were 486 microm(3), 9.76 microm, and granulocytes were 515 microm(3), 9.95 microm. In contrast, HPC-A samples prepared after lysis with FACSLysing solution had mean electronic volume and diameter of lymphocytes (414 microm(3), 9.25 microm), monocytes (797 microm(3), 11.5 microm), and granulocytes (670 microm(3), 10.85 microm). Cell volume of mononuclear cells in the HPC-A samples prepared by Histopaque-1077 sedimentation method was correlated with the expression of stem cell markers CD34, CD90, CD117, and CD133. CD90 positive cells had the smallest mean electronic volume of 299.93 microm(3) when compared with cells with positive expression of CD133 (322 microm(3)), CD117 (349 microm(3)), CD34 (407 microm(3)), and CD45 (453 microm(3)). Correlation of cell volume with stem cell marker expression may allow for the identification of small stem cells, which may not express the conventional markers used for the identification of stem cells in HPC-A samples.

Organic Electroluminescent Devices Using Eu~(3+) Complex as Red Emitting Layer (2000)

The new complex of Eu(BA)_2(MAA)(Phen) is synthesized and is used as a red light-emitting material in our organic electroluminescent devices with the structure of ITO/TPD/Eu(BA)_2(MAA)(Phen).The brightness of 15 cd/m~2 and luminous efficiency of 0.25 lm/W are achieved at the voltage of 26 V. This material has strong photoluminescence and relatively good electroluminescence along with excellent mono-chromaticity.The mechanism of this EL device is discussed.
Control Concept for Parallel Interleaved Three-Phase Converters with Decoupled Balancing Control (2018)

The parallel operation of multiple switches, modules or complete converters allows the realization of power electronic systems with high output currents. However, an equal distribution of the total current between the parallel modules has to be ensured to avoid excessive losses and the saturation of individual inductors. In this paper, a novel current balancing control approach is presented that is decoupled from the output voltage and current controllers and combines the benefits of an intuitive operation principle, simple controller design and low implementation effort. The analysis, discussion as well as the simulative verification of the concept are exemplarily performed for a three-phase four-wire grid connected 10 kVA converter for smart grid applications.
High Rate Electrodeposition of Niobium from Molten Fluorides Using Periodic Reversal Steps and the Effects on Grain Size (1981)

Application of periodic reversal (PR) technique, in which a cathodic (depositing) step is followed by an anodic (polishing) step, was found very beneficial to the increase of electroplating rate of coherent niobium. With no mechanical agitation, the application of the PR technique facilitated an electroplating rate increase by a factor of about 10 over the direct current method. The morphology of the deposits was found to be of the columnar structure. The columns became more oriented along the [100] direction, and of smaller diameters as the rate of electrodeposition increased. Unexpectedly, beyond a certain rate and under certain conditions, the columnar grains became large once again. Under such conditions a pronounced heteroepitaxial effect of the substrate (Cu) grains on the deposit grain size and orientation was observed.
The Effects of Iron on the Corrosion Resistance of Zirconium (1983)

Zirconium is one of the few metals that resists attack by sulfuric acid up to 75% concentration. However, selective corrosion may be found in welds at somewhat lower concentrations of sulfuric acid. It is generally believed that iron in zirconium plays an important role in degrading zirconium’s corrosion resistance. Zirconium-iron alloys were then prepared for corrosion testing. Zirconium crystal bar and pure iron were used to make Zr-50,240,460, and 800 ppm Fe alloys by using the consumable electrode technique. These ingots were also hot and then cold rolled to sheet material as required. Specimen conditions included as-cast, as-cast and heat treated, cold rolled, cold rolled and heat treated, welded, and welded and heat treated. Heat treatment was performed at 760 C for one hour. Standard immersion tests were conducted in 60, 65, 70, 75, and 77.5% H2SO4 at boiling temperature. Metallography was used to study the effect of heat treatment on the distribution of second phase particles. Potential differences between pure zirconium and pure iron in testing solutions were also determined. It has been found that lowering iron content can not really ensure zirconium’s corrosion resistance in sulfuric acid solutions. Heat treatment is an effective method to improve zirconium’s corrosion resistance. Corrosion rates of Zr-Fe alloys in sulfuric acid solutions can decrease up to two orders by the heat treatment method.
