A low-power 64–84GHz frequency quadrupler based on transformer-coupled resonators for E-Band backhaul applications (2016)

This paper presents a BiCMOS mm-Wave frequency quadrupler for E-band wireless backhaul applications. The circuit is intended to be a building block of a low-phase-noise E-Band frequency synthesizer. The multiplier employs transformer-coupled resonators for GBW enhancement and single-ended-to-differential conversion. The measured prototype achieves 27% fractional bandwidth around 74 GHz, with only 7mW power consumption.
High isolation dual-polarized patch antenna using integrated defected ground structure (2004)

This letter presents a high isolation dual-frequency orthogonally polarized rectangular patch antenna utilizing microstrip feed line integrated with a defected ground structure (DGS). The demonstrated approach results in a significant improvement in port isolation in comparison to a conventional dual-polarized antenna fed by simple microstrip lines. Measurements show an improvement of 20 dB in port isolation relative to the conventional antenna, operating at 2 and 2.5 GHz. Image impedance of a microstrip line with DGS is controlled by the DGS geometry without modifying the dimension of the line. A 150 /spl Omega/ high impedance line is effectively implemented using a microstrip line with 75 /spl Omega/ line width by incorporating the DGS.

Mapping the FDTD Application to Many-Core Chip Architectures (2009)

This paper reports a study of mapping the Finite Difference Time Domain (FDTD) application to the IBM Cyclops-64 (C64) many-core chip architecture [1]. C64 is chosen for this study as it represents the current trend in computer architecture to develop a class of many-core architectures with distinct features e.g. software manageable on-chip memory hierarchy (vs. a hardware-managed data cache), high on-chip bandwidth, fine grain multithreading and synchronization, among others. Major results of our study include: 1. A good mapping of FDTD can effectively exploit the on-chip parallelism of C64-like architectures and show good performance and scalability. 2. Such performance improvement is derived by employing a number of code optimization techniques such as time skewing and split tiling that judiciously exploit the architecture features described in (1). 3. High performance requires maximum reuse of on-chip memory, which is obtained by tiling with non conventional tile shapes. 4. Such code optimization techniques we used in (2) and tiling such as the one used in (3) should be implementable within a reasonable compilation framework, opening a new set of possibilities for compiler optimizations.
Novel Metal-Free Bis-silylation:  C60-Sensitized Reaction of Disilirane with Benzonitrile (1999)

The photochemical reaction of disilirane with C60 in benzonitrile affords the adduct of disilirane and benzonitrile as a bis-silylated product. In this reaction, C60 serves as a sensitizer. The results are reasonably accounted for by a novel metal-free bis-silylation of an unsaturated compound via a photoinduced electron-transfer process.
Circulating Markers of Endothelial Dysfunction and Platelet Activation in Patients with Severe Symptomatic Cerebral Small Vessel Disease (2013)

Our results confirm that chronic platelet activation, when compared to controls matched for age, sex and vascular risk factors, did not seem to play a central role in the pathophysiology of lacunar stroke. In contrast, we found markers of endothelial dysfunction, the role of which in the occurrence of lacunar infarction has still to be clarified in further studies.
GCD Computations Modulo Regular Chains (2010)

The computation of triangular decompositions involves two fundamental operations: polynomial GCDs modulo regular chains and regularity test modulo saturated ideals. We propose new algorithms for these core operations based on modular methods and fast polynomial arithmetic. We rely on new results connecting polynomial subresultants and GCDs modulo regular chains. We report on extensive experimentation, comparing our code to pre-existing Maple implementations, as well as more optimized Magma functions. In most cases, our new code outperforms the other packages by several orders of magnitude.
A GaN Schottky Diode-based analog phase shifter MMIC (2014)

A GaN Schottky Diode-based Analog Phase Shifter MMIC of T-topology has been designed for 35 GHz operation. An all E-Beam technology was employed for MMIC realization. The measured, as well modeled small and large-signal diode characteristics were used for evaluating the phase-shifter performance in view of its potential for robust power operation. The phase shifter presents analog phase shifting capability up to 45° with ~ 7 dB insertion loss and a maximum VSWR of 2:1 in the 32 to 38 GHz range. Good power handling capability and robust performance is demonstrated through large signal analysis and experimental characterization.
High Chromium Fe-Cr-Mo-P-C Amorphous Coating Films Produced by Thermal Spraying Technique (2011)

High chromium Fe-Cr-Mo-P-C amorphous coating films containing up to about 35 at% Cr having high hardness and high corrosion resistance have been produced by a newly developed thermal spraying technique. In order to control the temperatures of the powder particles in the flame spray and the substrate, a cylindrical nozzle, with external cooling nitrogen gas, was mounted to the front end of the thermal spraying gun. Fe70Cr10P13C7 and Fe38Cr35Mo7P13C7 films with various external cooling gas velocities between 20 m/s and 40 m/s exhibited entire amorphous structure without oxides and/or unmelted powder particles. High corrosion-resistance of the Fe38Cr35Mo7P13C7 amorphous coating film was observed in immersion tests using 35% hydrochloric acid.
Sticky costs and regulation in private healthcare providers (2021)

"This study aims to analyze the effects of the Brazilian National Supplementary Health Agency’s (NSHA) regulation on sticky costs of private healthcare providers (PHP). The research used financial and operational data from the NSHA analyzed through panel data regression and focused on PHP classified as medical cooperatives and group medicine between 2010 and 2018. The models developed employed different cost proxies (dependent variable) and explanatory variables. We verified that two cost proxies presented significant relations in all models: selling, general, and administrative expenses, and total cost. Concerning regulation variables, one was significant in the two studied modalities: PHP dependency ratio. This paper presents many contributions to different PHP’ stakeholders, such as NSHA, their managers, and Brazilian society. Among the main findings are (a) the importance of analyzing the organizations’ legal nature when examining sticky costs; (b) the proposal of different regulation variables to understand this phenomenon while displaying its importance in regulated industries; and (c) the relevance of employing different proxies when measuring sticky cost."
The Multiple-Relay Channel with Estimate-and-Forward Relaying (2007)

In this paper we consider the multiple-relay channel. For this scenario there are two well known results: the decode-and- forward (DAF) result of [Xie and Kumar, 2005] and the estimate-and forward (EAF) result of [Kramer et al., 2005]. However, the EAF result does not lend itself to numerical evaluation due to the large number of parameters to be determined and the non-convex nature of the optimization problem for finding the maximum rate. Therefore, for a given channel we cannot tell what is the EAF rate while keeping the expressions in their general form. We propose a specific assignment for the EAF auxiliary variables that satisfy the feasibility constraints and allow us to obtain an explicit EAF-based rate expression. This expression can be easily computed, and compared against the DAF- based rate. We give an example of a channel where this EAF rate is superior to both the DAF and the point-to-point rates.
RandSolomon: Optimally Resilient Random Number Generator with Deterministic Termination (2021)

Multi-party random number generation is a key building-block in many practical protocols. While straightforward to solve when all parties are trusted to behave correctly, the problem becomes much more difficult in the presence of faults. In this context, this paper presents RandSolomon, a protocol that allows a network of N processes to produce an unpredictable common random number among the non-faulty of them. We provide optimal resilience for partially-synchronous systems where less than a third of the participants might behave arbitrarily and, contrary to many solutions, we do not require at any point faulty-processes to be responsive.
Transmission over 362 km of 110 channels at 2.35 Gb/s from a spectrum-sliced femtosecond laser (1999)

We use temporal spectrum-slicing and optical time-division multiplexing to obtain 110 wavelength channels at 2.35 Gb/s from a single femtosecond fiber laser. We show that the output of this transmitter can be propagated over 362 km of standard single mode fiber using periodic amplification and dispersion compensation. Most transmitted channels have Q factors larger than 18.34 dB corresponding to error floors below 10/sup -16/.
Accelerated Construction of High-Silica RHO and CHA Zeolites via Interzeolite Transformation and Their NH3–SCR Performances after Copper Exchange (2018)

Rapid and selective synthesis of high-silica zeolites, including topologies of RHO and CHA, has been realized by interzeolite transformation process. The XRD patterns and morphology images collected within the whole procedure of aging and reaction suggest that the interzeolite transformation from FAU to RHO zeolite proceeds in a way of directly reassembling the locally ordered FAU-derived species, but as quasi-amorphous domains, on the surface of the RHO moieties. Therefore, the crystallization process could be remarkably accelerated by circumventing the incipient nucleation from the fundamental Si/Al species. Thenceforth, the high-silica descendant zeolites obtained by interzeolite transformation were all employed in the NH3–SCR process after copper ion exchange to a similar level. Therein, the RHO zeolite achieves fine trade-off between the activity and durability even after hydrothermal treatment at 800 °C, which indicates that the durability issue involved could be validly fixed by this zeolite and once again highlights the advantages of the interzeolite conversion process.
Identification of New Influenza B Virus Variants by Multiplex Reverse Transcription-PCR and the Heteroduplex Mobility Assay (1998)

A quick genetic approach for the screening of influenza virus variants was developed in this laboratory (S. Zou, J. Clin. Microbiol. 35:2623-2627, 1997). It uses multiplex reverse transcription and multiplex PCR to amplify and differentiate the variable region of the hemagglutinin genes of different types and subtypes of influenza viruses. Variants within the same type or subtype are then identified by the heteroduplex mobility shift assay of the amplicons. The method was used to screen influenza virus isolates received from provincial laboratories during the 1996-1997 season and was able to identify new influenza B virus variants. Sequencing of the amplicons derived from the hemagglutinin gene of the identified variants and comparison with the vaccine strain B/Harbin/7/94 showed substitution rates of 2.26 to 2.55% at the nucleotide level and 4.26 to 4.68% at the amino acid level. The result further demonstrated that the approach provides a quick, sensitive, and reliable screening for influenza virus variants. It also suggested the necessity of close monitoring of influenza B virus isolates in the 1997-1998 season and critical evaluation of the reference strain for the type B influenza virus.

Echocardiography Differentiates Lethally Irradiated Whole-Body From Partial-Body Exposed Rats (2018)

<b>Background:</b> Acute radiation syndrome (ARS) affects morbidity and mortality dependent on the amount of body exposed. We propose the use of echocardiography (EC) to differentiate between survivors and non-survivors by measuring changes in cardiac function (CF) and pulmonary arterial function (PAF). We also investigate the role of rheology in our observed changes. <b>Methods and Results:</b> Rats were irradiated to the whole body (WB) or partial body with two-legs shielded (2LS) at a lethal dose of 7.5Gy. EC and magnetic resonance imaging were performed, and rheological measurements conducted. Only 2LS survived past 12-days post-exposure and their CF and PAR were not significantly different from baseline. WB was significantly different from both baseline and 2LS in stroke volume (<i>P</i> < 0.05), velocity time integral (VTI; <i>P</i> < 0.05) and pulmonary artery acceleration time (PAAT; <i>P</i> < 0.05). Differences were identified as early as six-days post-exposure, where VTI and PAAT were significantly (<i>P</i> < 0.05) decreased in WB versus baseline but only PAAT was different from 2LS. Blood viscosity was significantly lower in the WB versus baseline and 2LS (<i>P</i> < 0.0001). WB exhibited a significant rise in dense red blood cells versus baseline (<i>P</i> < 0.01) and 2LS (<i>P</i> < 0.01). Cell-free hemoglobin, a contributor to pulmonary artery hypertension and vasculopathy, was significantly elevated in WB vs. sham. <b>Conclusions:</b> Non-invasive and readily available imaging can be used to identify critically affected victims. Our findings point to heart failure as one possible cause of death in WB exposed animals, potentially exacerbated by rheological, hemolytic, and pulmonary factors, and the importance of developing radiomitigators against cardiac ARS mortality.
Mode-Group Multiplexed Transmission using OAM modes over 1 km Ring-Core Fiber without MIMO Processing (2017)

We demonstrate mode-group multiplexed transmission over 1km ring-core fiber to transmit 2×10Gbit/s using OOK modulation and direct detection. SLM based spatial (de)multiplexers perform all-optical multiplexing and demultiplexing in an OAM mode basis.
On the optimization of heterostructure avalanche photodiodes (2003)

We use the modified dead-space multiplication theory (MDSMT) that incorporates both the initial energy effect and the heterostructure effect to predict the optimal performance of two-layered-multiplication APDs. We first consider an Al/sub 0.6/Ga/sub 0.4/As homojunction APD with a multiplication layer (i-layer) of width 140 nm, and then a device with a multiplication region consisting of two layers: Al/sub 0.6/Ga/sub 0.4/As and GaAs for which carriers are injected into the Al/sub 0.6/Ga/sub 0.4/As layer. From a design perspective, maximizing the initial energy is clearly the key in reducing noise. Unfortunately, the ability to control the initial energy in the fabrication stage is apparently not yet well established at this point of time. However, for a given initial energy of the injected electrons, the heterostructure APD would result in improved noise performance if the Al/sub 0.6/Ga/sub 0.4/As layer is either 30 nm or 110 nm wide. Moreover, the 30 nm Al/sub 0.6/Ga/sub 0.4/As case would result in less uncertainty in the excess noise factor than the 110 nm case (/spl Delta/F=0.7 vs. /spl Delta/F =2.3), which is attributed to the unknown initial energy.
An Analysis on Islamic Insurance Participation (2012)

Inexpensive and Reliable Monitoring of the Microdeposition of Biomolecules (2014)

Anti-C-reactive protein antibody is used to quantify C-reactive protein in diagnostic tests for assessing inflammation levels. In order to develop a practical chip for diagnostic tests, anti-C-reactive protein antibody was continuously ejected using a piezoelectric injector and microdeposition was monitored on a shot-by-shot basis using a 30 MHz quartz crystal microbalance. Background noise due to external sources such as air flow and temperature fluctuations were largely eliminated by covering the quartz crystal microbalance with a stainless-steel cover and maintaining a fixed distance between the optical microscope lamp and the piezoelectric injector. Each shot of a 1 mg ml−1 solution of anti-C-reactive protein antibody solution delivered approximately 30 pl to the quartz crystal microbalance. The frequency change per shot was 2.21 ± 0.97 Hz and the injected mass was estimated to be 44.2 pg using the Sauerbrey equation. This approach simplifies the experimental evaluation of inkjet bioprinting by allowing the sensitive determination of shot ejection mass and volume, and realizes label-free detection, continuous monitoring, and simple temperature control. Measurements can be performed at atmospheric pressure and at room temperature. Furthermore, the system uses only commercially available devices.
The evolution of Bernstein modes in quantum wires with increasing deviation from parabolic confinement (1996)

We investigate the evolution of the interaction of the magnetoplasmon resonance with the harmonics of the cyclotron resonance as the confinement of an electron gas in a quantum wire increasingly deviates from the parabolic case. The occurrence of the Bernstein modes is observed in a time-dependent Hartree model of a two-dimensional electron gas in a single quantum wire.
Federated Service Chaining: Architecture and Challenges (2020)

Emerging edge computing has seen latency- sensitive services moving rapidly from cloud to the edge to take advantage of its close vicinity to end users, while cloud is retained for carrying out latency-insensitive and computation-intensive tasks. When more edge computing service providers come to the market, the network will become increasingly more fragmented because of their proprietary services and policies deployed in the network. This means that the Internet can become more cumbersome and riskier as there will be more tiers and potential vulnerabilities that could be exploited. To tackle this issue, we envisage a federated service chaining paradigm in which operators can share and put service functions in other participants' networks so as to improve resource utilization, collaboratively mitigate cyber threats, and enable service innovations. In this position article, building on our past experience in enabling federated cloud infrastructure and heterogeneous service chaining, we present a Federated Service Chaining architecture followed by discussions of its key components. Several key research challenges are described for the successful realization of such architecture. We hope this article can open a discussion in the research community and generate enough research interest to significantly advance this field.
A Total Synthesis of (±)-Longicyclene (1973)

Abstract Synthetic quests within the longifolane class of sesquiterpenes have included such elaborately bridged structures as longifolene,1 isolongifolene,2 and culmorin.3 The tetracyclic member of this interesting group of naturally occurring compounds; namely, longicyclene (1)4 has heretofore evaded synthesis. Longicyclene (1), isolated from turpentine oil of Pinus longifolia, was assigned structure 1 on the basis of spectral evidence and an acid-catalyzed conversion to longifolene.4,5 We wish to report herein a stereoselective total synthesis of (±)-longicyclene (1).
Evaluating the use of functionally graded materials inserts produced by selective laser melting on the injection moulding of plastics parts (2007)

The demand for productivity and shape complexity on the injection moulding industry necessitates new research to improve tool design, material, and manufacturing. A research field is the development of functionally graded materials (FGMs) to build injection moulds. For example, moulds built with the FGMs technique can have distinctive regions with higher heat conduction. Higher rates of heat transfers from thicker regions of the injected part can be useful to produce better and cheaper injection moulded polymer parts. It is possible to obtain moulds with differential conductivity by adding locally, during the fabrication of the mould, copper to the mould base material such as tool steel. In this work, an investigation into the effect of FGM copper (Cu)-tool steel mould insert over polymer injected parts is presented. The work is divided in two parts: a numerical thermal analysis comparison between Cu-tool steel graded and tool steel inserts and an injection moulding experiment with comparisons between mould surface temperature and degree of crystallinity of polypropylene parts. The numerical model was used to compare different behaviour of the mould heat transfer according to the mould insert material. Thereafter, a bolster was built to hold FGMs and tool steel inserts obtained by a selective laser fusion process. Polypropylene was injected over the inserts to compare with the numeric results. To observe the effect of the cooling rate in the polypropylene parts using the graded inserts, the degree of crystallinity of the parts was measured by differential scanning calorimetry (DSC) test. The temperature of the mould was also evaluated during the injection cycles. The results showed that the graded Cu-tool steel inserts tested had lower capacity to store heat energy. As Cu was added to the tool steel, the mixture proved to transfer heat more efficiently but it had less capacity to absorb heat.

Formation and Stabilization of a Decanuclear CuII Wheel Linked by Chloride and O⋅⋅⋅H−N Hydrogen Bonds (2001)

Copper gets into the ring: A decanuclear cyclic CuII complex is synthesized by direct treatment of CuCl2 with a fluorinated amino alcoholate containing one secondary and one tertiary nitrogen donor (see space-filling diagram; Cu light blue, Cl yellow, O red, N dark blue, C gray). Possible factors that lead to the self-assembly of the unique molecular wheel are discussed.
