SONoMA: A Service Oriented Network Measurement Architecture (2010)

To characterize the structure, dynamics and operational state of the Internet it requires distributed measurements. Although in the last decades several systems capable to do this have been created, the easy access of these infrastructures and orchestration of complex measurements is not solved. We propose a system architecture that combines the flexibility of mature network measurement infrastructures such as PlanetLab or ETOMIC with the general accessibility and popularity of public services like Web based bandwidth measurement or traceroute servers. To realize these requirements we developed a multi-layer architecture based on Web Services and the basic principles of SOA, which is a very popular paradigm in distributed business application development. Our approach opens the door to perform complex network measurements, handles heterogeneous measurement devices, automatically stores the results in a public database and protects against malicious users as well. To demonstrate our concept we developed a public prototype system, called SONoMA.
Transonic Compressor Rotor Design Using Non-Monotonic Meanline Angle Distribution (2007)

A non-monotonic meanline angle distribution technique with local negative camber is applied to a transonic rotor blade from the hub area to tip with the inlet Mach number varying from subsonic to low supersonic. The blade passage area is controlled by the non-monotonic meanline angle distribution, which results in reduced peak Mach number and weakened or removed shock wave. The negative camber is used downstream of the throat and hence it does not affect the flow passing capability of the blade section. The design point efficiency is significantly increased and the stall margin at part speed is also improved. Detailed results are given in the paper.
Orbital Unsymmetrization of Olefins Arising from Non-equivalent Orbital Interactions. .SIGMA.-.PI. Coupling in Bicyclo(2.2.2)octenes. (1996)

We characterized experimentally the substituent effect of a 5-exo substituent on the π facial selectivities of bicyclo[2.2.2]octenes toward electrophilic oxidative reactions such as epoxidation and dihydroxylation, and we discuss the underlying orbital interactions of vicinal σ orbitals and the olefinic π orbital involved in bicyclo[2.2.2]octenes, and commonly in methylenenorbornanes. Of significance is the out-of-phase motif of these σ-π couplings. Electron-withdrawing substituents such as cyano and carboxylic acid groups unequalize the relevant σ-π coupling, leading to the observed syn-facial preference. Alkyl substituents exhibit an electron-donative perturbing effect, depending on the bicyclic ring system.
An E-band, scalable 2×2 phased-array transceiver using high isolation injection locked oscillators in 90nm SiGe BiCMOS (2016)

This paper presents the first E-band phased array transceiver that uses injection locked oscillators (ILOs) for beamforming. We propose a current injection distribution network with wide locking range and high isolation. A 2×2 bidirectional transceiver is demonstrated to operate from 71-86 GHz and measurements verify that each oscillator can be controlled independently with phase shift over ±300 degrees with <; 5° phase error and under 0.9 dB amplitude variation. Each channel has a 9.5-dB noise figure in RX mode and a 10-dBm output power in TX mode. The phase noise of the locked oscillator exhibits less than 2.5 dB variation across the phase steering range. The 90-nm SiGe BiCMOS chip consumes 386.4 mW in TX mode and 286 mW in RX mode per channel.

GAS TURBINE PREDIFFUSER-COMBUSTOR PERFORMANCE DURING OPERATION WITH AIR-WATER MIXTURE. (1994)

In a continuing effort to establish performance changes due to water ingestion into an aircraft gas turbine engine and possible design improvements, an experimental investigation was performed with a model gas turbine prediffuser-combustor sector utilizing a number of mixture and flow conditions in a tunnel operating with a two-phase, air-liquid film-droplet mixture. For given entry conditions into the prediffuser (which can be related to the exit conditions of the core compressor in a bypass engine, and, therefore, also to ingestion conditions at the engine face) the two main issues are (1) the amount of water entering the primary zone of the combustor, and (2) the local reduction in temperature, flame-water interactions, and the vitiation caused by the vaporizing of water. Flow visualization and estimates of water flow and droplet size in the primary zone have been undertaken under cold flow conditions. The amount of water entering the primary zone has been found to be a complex function of (1) the air-water mixture conditions at entry to the prediffuser, and (2) the effects of gravity on the flowfield for given geometry of the prediffuser-combustor, and the flow split between the primary and the coolant streams in the combustor. Combustion tests have been carried out to establish the effects on performance, occurrence of flameout, and recoverability of combustor exit temperature by enhancement of one or both of the fuel equivalence ratio and the oxygen content of air.

Generating comics from 3D interactive computer graphics (2006)

Storyboards and scripts use comic-like frames to narrate stories. Such displays can also summarize the main events in a film, video, or virtual world interaction creating a more succinct representation of the original graphics. Our goal is to create a sequence of comic-like images summarizing the main events in a virtual world environment and present them in a coherent, concise, and visually pleasing manner. Our system can extract a sequence of important events from a continuous temporal story line and convert the events into a graphical representation automatically. Our automatic end-to-end system transforms interactions in 3D graphics into a succinct representation depicted by comics. The system is based on principles of comic theory and can produce different comic sequences on the basis of user-provided semantic parameters, such as viewpoint and level-of-details using the same reduction principle in both the temporal and the spatial domains.
Comfort and discomfort vs. safety, quality, productivity and marketability (1998)

Comfort and discomfort are frequently measured in ergonomic evaluation studies, often interchangeably. The main intent of this concept paper is to argue that comfort and discomfort may not be two extremes of a continuum, and may reflect two orthogonal dimensions in perception and may have different ramifications for safety, quality, productivity and marketability. Arguments are presented that different factors possibly impact these constructs, and that especially for consumer products Ergonomists are well advised to identify these factors and use them appropriately to get the most leverage.
Characterization and Application of a Hybrid Optical Microscopy/Laser Ablation Liquid Vortex Capture/Electrospray Ionization System for Mass Spectrometry Imaging with Sub-micrometer Spatial Resolution (2015)

A commercial optical microscope, laser microdissection instrument was coupled with an electrospray ionization mass spectrometer via a low profile liquid vortex capture probe to yield a hybrid optical microscopy/mass spectrometry imaging system. The instrument has bright-field and fluorescence microscopy capabilities in addition to a highly focused UV laser beam that is utilized for laser ablation of samples. With this system, material laser ablated from a sample using the microscope was caught by a liquid vortex capture probe and transported in solution for analysis by electrospray ionization mass spectrometry. Both lane scanning and spot sampling mass spectral imaging modes were used. The smallest area the system was able to ablate was ∼0.544 μm × ∼0.544 μm, achieved by oversampling of the smallest laser ablation spot size that could be obtained (∼1.9 μm). With use of a model photoresist surface, known features as small as ∼1.5 μm were resolved. The capabilities of the system with real world samples were demonstrated first with a blended polymer thin film containing poly(2-vinylpyridine) and poly(N-vinylcarbazole). Using spot sampling imaging, sub-micrometer sized features (0.62, 0.86, and 0.98 μm) visible by optical microscopy were clearly distinguished in the mass spectral images. A second real world example showed the imaging of trace amounts of cocaine in mouse brain thin tissue sections. With use of a lane scanning mode with ∼6 μm × ∼6 μm data pixels, features in the tissue as small as 15 μm in size could be distinguished in both the mass spectral and optical images.

Measurement of the CP -violating phaseϕsinB¯s0→J/ψπ+π−decays (2014)

The mixing-induced CP-violating phase s in B 0 s and B 0 s decays is measured using the J / + -final state in data, taken from 3 fb -1 of integrated luminosity, collected with the LHCb detector in 7 and 8 TeV centre-of-mass pp collisions at the LHC. A time-dependent flavour-tagged amplitude analysis, allowing for direct CP violation, yields a value for the phase s = 70 68 8 mrad. This result is consistent with the Standard Model expectation and previous measurements.
Trace Element Conundrum of Natural Quasicrystals (2021)

We report laser ablation inductively coupled plasma mass spectrometry measurements of the trace element contents of the two naturally occurring quasicrystalline minerals, Al63Cu24Fe13 icosahedrite and Al71Ni24Fe5 decagonite, from their type locality in the Khatyrka meteorite. The isolated quasicrystal fragments were mounted separately from any matrix and are larger than the laser beam diameter. When the elements are sorted in order of volatility, a systematic and unique pattern emerges in both bulk natural quasicrystal specimens. They are highly depleted compared to primitive solar system materials (chondritic meteorites) in moderately refractory elements (those with 50% condensation temperatures near 1350−1300 K; V, Co, Mg, Cr) and significantly enriched in moderately volatile elements (those with 50% condensation temperatures between 1250 and 500 K; Sb, B, Ag, Sn, Bi). We compare the chondrite-normalized trace element patterns and ratios of the quasicrystals to those of scoriaceous cosmic spherules and other meteoritic components. &#13;\nThe nonmonotonic shapes of the chondrite-normalized trace element patterns in both icosahedrite and decagonite are incompatible with&#13;\na single condensation process from the gas of the solar nebula. Previous transmission electron microscopy studies show that the&#13;\nnatural quasicrystals contain 3−5 vol % of silicate and oxide nanoparticle inclusions, which we consider to be the main host of the&#13;\nmeasured trace elements. On this basis, we construct a three-stage model for the formation of the quasicrystals and their inclusions: a&#13;\nhigh-temperature condensation stage and a low-temperature vapor-fractionation stage to make nanoparticles, followed by a third&#13;\nstage that leads to the formation of quasicrystals incorporating the two different types of nanoparticles and their incorporation into&#13;\nthe CV chondrite parent body of the Khatyrka meteorite.
Early Steps of a Thymic Tumor in SV40 Transgenic Mice: Hyperplasia of Medullary Epithelial Cells and Increased Mature Thymocyte Numbers Disturb Thymic Export (2002)

Bone marrow progenitors migrate to the thymus, where they proliferate and differentiate into immunologically competent T cells. In this report we show that mice transgenic for SV40 T and t antigens under the control of the L-pyruvate kinase promoter develop, in a first step, thymic hyperplasia of both thymocytes and epithelial cells. Morphological studies (histology, immunohistolabeling and electron microscopy) revealed modifications of the thymic microenvironment and gradual expansion of medullary epithelial cells in 1 month-old mice, taking over the cortical region. Then, a thymic carcinoma develops. Two-color labeling of frozen sections identified the transgene in medullary epithelial cells. Flow cytometry analysis demonstrated a marked increase in mature CD4+ and CD8+ thymocytes in adult mice (39 +/- 10 x 10(6) in transgenic mice and 12 +/- 5 x 10(6) in age-matched controls). Furthermore, thymocyte export was disturbed.
Design and fabrication of an InP-based moving waveguide 1/spl times/2 optical MEMS switch (2003)

Design and fabrication of 1/spl times/2 InP-based MEMS moving waveguide optical switch with low switching voltage and low loss is presented.

Factors Affecting Hemodialysis and Peritoneal Dialysis Efficiency (2001)

Hemodialysis and peritoneal dialysis are two blood purification techniques that use similar operating systems. The hemodialysis system is based on three components (blood, membrane, and dialysate). The peritoneal dialysis system is based on the same components that can, however, be less manipulated and adjusted. In hemodialysis the blood flow is the main determinant of small solute removal thanks to a prevalently diffusive mechanism. Convection is also used to transport larger solutes across the membrane, but this mechanism relies on the high permeability coefficient of the membrane and high transmembrane pressure leading to high ultrafiltration rates. The membrane can therefore influence the performance of the techniques as far as solute removal and ultrafiltration are concerned. Finally, diffusion is facilitated by an improved distribution of dialysate flow in the dialysate compartment. This can be achieved with a special dialysate pathway configuration based on space yarns or micronodulation of the fibers. In peritoneal dialysis, blood flow and membrane characteristics can be less manipulated or almost not at all. The only variables are dialysate volume, flow, dwell time, and composition. Thanks to modification in these aspects of the dialysate, peritoneal dialysis techniques with different clearances and ultrafiltration rates can be accomplished.
Response of magnesium microcrystals to c-axis compression and contraction loadings at low and high strain rates (2023)

In this work, 99.999% pure magnesium (Mg) single microcrystals have been deformed in [0001] compression (c-axis compression) and [101¯0] tension (c-axis contraction) conditions at room temperature and under loading rates ranging from 5 × 10−4 up to ∼590 s−1. The strain rate sensitivity and apparent activation volume of prismatic and pyramidal slip systems were evaluated. In c-axis contraction, at strain rates of 45 s−1, the formation of a new grain whose crystallographic characteristics do not correspond to those of well-known twin systems could be observed. An explanation was found but it requires the breakdown of the invariant plane strain condition, and a unit cell reconstruction via pyramidal II to basal plane transformation. This unconventional twin is at 2.1° far from a classical simple shear twin on {101¯5} planes. In c-axis compression, at the highest applied strain rate, no twin could be detected in the 5 μm sized pillars of 2:1 (height to width) aspect ratio. Plasticity is thus purely mediated by slip. However, the appearance of newly oriented grains was observed by lowering the sample size or by reducing the aspect ratio. Their crystallographic features suggest a mechanism of unit cell reconstruction through the transformation from pyramidal I to basal plane. The results presented in this study impose to consider twinning as a reorientation mechanism not necessarily limited to a simple shear.
ORALLY ADMINISTERED IMMUNOSUPPRESSANTS MODIFY INTESTINAL UPTAKE OF NUTRIENTS IN RABBITS (1994)

The effect on intestinal nutrient transport of the immunosuppressive drugs cyclosporin A (CsA), cyclosporin G (CsG), and rapamycin (RAP) was determined in New Zealand white rabbits. Rabbits received oral doses of CsA (20 mg/kg/day), CsG (10 mg/kg/day), or RAP (1 mg/kg/day) for 10 days. Animals receiving RAP had decreased food intake and weight gain compared with controls. This correlated with a decrease in both total ileal weight and corresponding mucosal weight. CsA and CsG administration had no effect on food intake, total weight gain, or intestinal weight. Villus surface area was significantly decreased in all groups as compared with controls. Jejunal uptake of D-glucose as well as 1 medium and 4 long chain fatty acids was not affected by drug administration, while both mucosal-to-serosal and net 3–0-methylglucose fluxes were increased (P<0.05) in the jejunum by all 3 drugs. In the ileum, the rates of uptake of D-glucose as well as stearic and linoleic acids were increased in animals treated with RAP compared with controls. There was an increase in the ileal values of the maximal transport rate (Vmax) and apparent Michaelis constant (Km*) in RAP, and a fall in the Vmax and Km* in CsG. CsG administration resulted in a decreased cholesterol uptake in both jejunum and ileum, and a decreased D-glucose uptake in the ileum compared with controls. These differences in glucose uptake among groups could not be attributed to variations in body, intestinal, or mucosal weights. It is unlikely that the changes observed in CsA- and CsG-treated animals would have nutritional importance, as these animals gained weight normally. In addition, in these animals the changes mainly occurred in the ileum, not in the jejunum, where most glucose is absorbed, and the associated alterations in the values of the Vmax and Km* would lead to reciprocal changes in the rates of uptake of varying luminal concentrations of glucose. In contrast, these changes are likely to be of more importance in RAP-treated animals, since they failed to gain weight normally. The significance of these findings needs to be established in chronically treated animals.

Mode locked and distributed feedback silicon evanescent lasers (2008)

Abstract Electrically pumped lasers that can be made on silicon and integrated with other components are important in order to take full advantage of the capabilities of silicon photonics. In this paper we review two specific types of hybrid silicon evanescent lasers that can fulfill these requirements. We discuss recent results of distributed feedback (DFB) lasers and mode locked lasers made on silicon using evanescent coupling to thin films of III‐V material. Device designs and test results are discussed in detail.
SiC MESFET with output power of 50 watts CW at S-band (2002)

A SiC MESFET with 42 mm gate periphery on a single die had a maximum RF output power of 53 W CW with 37% power-added efficiency (PAE) at 3.0 GHz. This unprecedented power from a die with an area of only 3 mm/sup 2/ demonstrates the extremely high power handling capability of SiC microwave devices. Additionally, we report here SiC MESFETs showing 2.5 W/mm performance with 41% PAE at 8 GHz, demonstrating the utility of this technology at X-band.
A new HVDC grid test system for HVDC grid dynamics and protection studies in EMT-type software (2015)

This paper proposes a new HVDC grid test system for electromagnetic transient analysis, suitable for HVDC power system studies ranging from protection to dynamic studies investigating converter behaviour and interactions. In the recent past research interest in HVDC grids has increased, leading to a multitude of studies concerning dc power flow and optimal power flow, dynamics and HVDC grid protection. However, each of these studies makes use of different grid topologies, configurations and transmission line parameters. In this paper, a standard HVDC grid test system is proposed and an implementation in EMT-type software is provided. The implementation in EMT-type software makes use of a frequency dependent cable model, continuous converter model and a reduced dc breaker model. By means of a protection study, the effectiveness and computational efficiency of the proposed HVDC grid test system is demonstrated. The model with its parameters will be made publicly available.
A Practical Approach to the Synthesis of Dianhydro Sugars (1997)

Abstract Chiral tetrols derived from various carbohydrate precursors have been converted into the corresponding dianhydro sugar derivatives in a one pot procedure. The course of reaction very much depends upon the protecting groups used. In case of D-mannitol and sorbitol, it has been shown that when 3,4-hydroxy groups are protected as trans-acetonide group, the present methodology furnished exclusively 1,2: 5,6-dianhydro derivatives in excellent yield. However, if the 3,4-hydroxy groups are protected with benzyl group a mixture of products consisting of dianhydro sugar, a furan and a bicyclo[2.2.2]octane derivatives were obtained. This method has also been used to synthesize dianhydro sugars in which the two diol moieties are placed adjacent to each other or separated by one or more carbon atoms.
On the Research of Non Reciprocal Fin-Line Devices (2006)

In this paper, a semiconductor based fin-line isolator is analyzed. This device is based on field displacement effect phenomenon arising in a gyroelectric semiconductor (a theoretical method is presented). It is mainly an extension of the well known spectral domain approach. For this purpose, the semiconductor layer is taken into account through its conductivity tensor. Two semiconductors (GaAs and InSb) have been considered. The main parameters of the isolator such as isolation, insertion losses, band width are computed and compared with the experimental results. There is satisfactory agreement between theoretical and experimental results in the case of the GaAs. Finally it is pointed out that the InSb is the best choice.
