Communication and Consensus Co-Design for Distributed, Low-Latency, and Reliable Wireless Systems (2020)

Designing distributed, fast, and reliable wireless consensus protocols is instrumental in enabling mission-critical decentralized systems, such as robotic networks in the Industrial Internet of Things (IIoT), drone swarms in rescue missions, and so forth. However, chasing both low-latency and reliability of consensus protocols is a challenging task. The problem is aggravated under wireless connectivity that may be slower and less reliable, compared to wired connections. To tackle this issue, we investigate fundamental relationships between consensus latency and reliability through the lens of wireless connectivity, and co-design communication and consensus protocols for low-latency and reliable decentralized systems. Specifically, we propose a novel communication-efficient distributed consensus protocol, termed random representative consensus (R2C), and show its effectiveness under gossip and broadcast communication protocols. To this end, we derive a closed-form end-to-end (E2E) latency expression of the R2C that guarantees target reliability, and compare it with a baseline consensus protocol, referred to as referendum consensus (RC). The result shows that the R2C is faster compared to the RC and more reliable compared when co-designed with the broadcast protocol compared to that with the gossip protocol.
Brain white-matter hyperintensities and treatment outcome in major depressive disorder (2006)

Subcortical white-matter hyperintensities in the left hemisphere (but notin other brain areas) maybe associated with poor response to antidepressant treatment in major depression.
MglA/SspA Complex Interactions Are Modulated by Inorganic Polyphosphate (2013)

The transcription factors MglA and SspA of Francisella tularensis form a heterodimer complex and interact with the RNA polymerase to regulate the expression of the Francisella pathogenicity island (FPI) genes. These genes are essential for this pathogen's virulence and survival within host cells. Our goal was to determine if an intracellular metabolite modulate these protein/protein interactions. In this study, we identified inorganic polyphosphate (polyP) as a signal molecule that promotes the interaction of MglA and SspA from F. tularensis SCHU S4. Analysis of the Mgla/SspA interaction was carried out using a two-hybrid system. The Escherichia coli reporter strain contained a deletion on the ppK-ppX operon, inhibiting polyP synthesis. The interaction between MglA and SspA was significantly impaired, as was the interaction between the MglA/SspA complex and the regulatory protein, FevR, indicating the stabilizing effect of polyP. In F. tularensis, chromatin immune precipitation studies revealed that in the absence of polyP, binding of the MglA/SspA complex to the promoter region of the pdpD, iglA, fevR and ppK genes is decreased. Isothermal titration calorimetry (ITC) indicated that polyP binds directly to the MglA/SspA complex with high affinity (KD = 0.3 µM). These observations directly correlated with results obtained from calorimetric scans (DSC), where a strong shift in the mid-transition temperature (Tm) of the MglA/SspA complex was observed in the presence of polyP.
Demonstration of Optical 3R Regenerator for 10 Gb/s NRZ signal in Reconfigurable Recirculating Loop Transmission (2006)

This paper demonstrates optical 3R regeneration for a 10 Gb/s nonreturn-to-zero (NRZ) data format. Semiconductor optical amplifier based Mach-Zehnder interferometer (SOA-MZI) wavelength converters, synchronous modulator, and Fabry-Perot filter (FPF) are used for 3R regenearation including all-optical clock recovery. Recirculating loop transmission experiments compare transmission performances with different 3R regenation spacings. Transmission with the 3R regenerator shows significant performance improvement over that without 3R regeneration in terms of eye diagram, Q-factor, and transmission distance. Q-factors around 20 dB are obtained up to a transmission distance of 5000 km when the 3R regeneration spacing is 100 or 500 km.
Zidovudine resistance of human immunodeficiency virus. Discussion (1990)

The observation that human immunodeficiency virus resistant to zidovudine can be isolated from patients with AIDS or AIDS-related complex during prolonged zidovudine treatment was made with a plaque reduction assay employing a CD4-expressing HeLa cell line. Fifty percent inhibitory concentrations of zidovudine for isolates from untreated patients ranged from 0.01 to 0.05 gM. In contrast, most isolates from these patients showed decreased sensitivity after 6 months or more of zidovudine administration. Isolates from several patients showed progressive, stepwise reductions in sensitivity. Zidovudine-resistant isolates exhibited cross resistance to 3'-azido-2',3'-dideoxyuridine and 3'-azido-2',3'dideoxyguanosine but not to dideoxycytidine, dideoxyinosine, foscarnet (phosphonoformate), or several other compounds. The clinical implications of these findings have yet to be determined. Studies are in progress to assess sensitivity patterns of isolates from patients who are at earlier stages of human immunodeficiency virus disease or who are receiving other drug therapy and to characterize the mutations and mechanisms accounting for resistance.
Zipping transmission for infrastructure-assisted cloud network system (2016)

The usual built-in navigation in a car needs to be upgraded periodically due to the update and change of road conditions. To solve those problems, a cloud network navigation system has been launched which can automatically request the information of roads needed. However sending the information to each user in a specific area individually is very inefficient in the radio resource utilization aspect. In this paper, we model the transmission architecture that can send geographical information to the vehicle using RSUs, and propose a new method called Zipping algorithm. Our proposed algorithm groups the car in efficient way and due to our scheme; the total transmission time will be minimized. To make this possible, we use N times M/M/N which is an extension of M/M/1 model of queueing theory. We show the different traffic congestion of the road depends on the weekdays and weekends. Then, we show the case of car groupings depending on the various Zipping time given. We analyze the above result by simulating the transmission efficiency and compare with the performance of unicast system and that of our proposed algorithm.
Prostaglandin D2 synthase and its post‐translational modifications in neurological disorders (2005)

Prostaglandin D2 synthase (PGDS) (beta-trace protein) is a highly abundant cerebrospinal fluid (CSF) glycoprotein. A number of studies have been performed to determine the potential value of this protein for the diagnosis of various neurological disorders. The measurement of total PGDS levels in CSF has proved marginally useful for this purpose, but promising results were obtained while investigating changes in the posttranslational modifications (PTM) pattern. Using 2-DE analysis, we previously showed that PGDS is differentially expressed in ante- and post mortem CSF samples. In the present study, we examined whether the PGDS isoforms may help to distinguish stroke and neurodegenerative disease patients from healthy subjects. The pattern of PGDS PTM was analyzed in CSF from patients with various neurological disorders (n = 44) using IEF/immunoblotting techniques. Strong alterations of this pattern were detected in patients with different forms of degenerative dementia. These findings are consistent with PGDS being altered in some neurological diseases and provide new opportunities for clinical applications.
Simulation of cooperating robot manipulators on a mobile platform (1991)

The dynamic equations of motion are presented for two or more cooperating manipulators on a freely moving mobile platform. The system of cooperating robot manipulators forms a closed kinematic chain where the force of interaction must be included in the formulation of robot and platform dynamics. The formulation includes the full dynamic interactions from arms to platform and arm tip to arm tip, and the possible translation and rotation of the platform. The equations of motion are shown to be identical in structure to the fixed-platform cooperative manipulator dynamics. The structure of the closed-chain dynamics, allows the use of any solution for the open topological tree of base and manipulator links. The number of degrees of freedom (DOF) of the system is sufficiently large to make recursive dynamic calculation methods potentially more efficient than closed-form solutions. A complete simulation with two 6-DOF manipulators of a free-floating platform is presented along a with a multiple-arm controller to position the common load.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Hydration Shell Parameters of Aqueous Alcohols: THz Excess Absorption and Packing Density (2012)

Solvation in water requires minimizing the perturbations in its hydrogen bonded network. Hence solutes distort water molecular motions in a surrounding domain, forming a molecule-specific hydration shell. The properties of those hydration shells impact the structure and function of the solubilized molecules, both at the single molecule and at higher order levels. The size of the hydration shell and the picoseconds time-scale water dynamics retardation are revealed by terahertz (THz) absorption coefficient measurements. Room-temperature absorption coefficient at f = 0.28 [THz] is measured as a function of alcohol concentration in aqueous methanol, ethanol, 1,2-propanol, and 1-butanol solutions. Highly diluted alcohol measurements and enhanced overall measurement accuracy are achieved with a THz absorption measurement technique of nL-volume liquids in a capillary tube. In the absorption analysis, bulk and interfacial molecular domains of water and alcohol are considered. THz ideal and excess absorption coefficients are defined in accordance with thermodynamics mixing formulations. The parameter extraction method is developed based on a THz excess absorption model and hydrated solute molecule packing density representation. First, the hydration shell size is deduced from the hydrated solute packing densities at two specific THz excess absorption nonlinearity points: at infinite alcohol dilution (IAD) and at the THz excess absorption extremum (EAE). Consequently, interfacial water and alcohol molecular domain absorptions are deduced from the THz excess absorption model. The hydration shell sizes obtained at the THz excess absorption extremum are in excellent agreement with other reports. The hydration shells of methanol, ethanol, 1- and 2-propanol consist of 13.97, 22.94, 22.99, and 31.10 water molecules, respectively. The hydration shell water absorption is on average 0.774 ± 0.028 times the bulk water absorption. The hydration shell parameters might shed light on hydration dynamics of biomolecules.

Serodiagnosis of ocular toxocariasis: a comparison of two antigens. (1985)

This study was designed to compare the sensitivity and specificity of enzyme linked immunosorbent assay (ELISA) for the serodiagnosis of ocular toxocariasis using Toxocara canis embryonated egg antigen (TEE) and toxocara excretory-secretory or exoantigen (TEX) produced in vitro. TEE and TEX ELISA were comparably sensitive, but TEX ELISA was better able to discriminate between serum samples from patients with ocular toxocariasis and those from patients with retinoblastoma. In addition, preabsorption of sera with Ascaris suum embryonated egg antigen seemed to be essential to prevent false positive results with TEE ELISA but was not so critical for TEX-ELISA. Further studies are still required to standardise TEX for serodiagnosis.

Cavity quantum electrodynamics with a single quantum dot coupled to a photonic molecule (2012)

We demonstrate the effects of cavity quantum electrodynamics for a quantum dot coupled to a photonic molecule consisting of a pair of coupled photonic crystal cavities. We show anticrossing between the quantum dot and the two supermodes of the photonic molecule, signifying achievement of the strong coupling regime. From the anticrossing data, we estimate the contributions of both mode-coupling and intrinsic detuning to the total detuning between the supermodes. Finally, we also show signatures of off-resonant cavity-cavity interaction in the photonic molecule.
Direct liquefaction proof-of-concept program (1997)

The POC Bench Option Project (PB-Series) is geared to evaluate different novel processing concepts in catalytic direct coal liquefaction and coprocessing of organic wastes such as plastics, heavy resids, waste oils, and ligno-cellulose wastes with coal. The new ideas being explored in this program include using novel dispersed slurry catalysts and combinations of dispersed and supported catalysts (hybrid mode), and coprocessing of coal with waste plastics, low quality resids, waste oils, and ligno-cellulosic wastes, etc. The primary objective of bench run PB-07 was to study the impact of dispersed catalyst composition and loading upon the direct liquefaction performance of a high volatile bituminous Illinois No. 6 coal. The run was carried out for 20 operating days (including the four days used for the production of O-6 bottoms material for West Virginia University), spanning over five process conditions. Results are reported.
CMOS Photonic Circuits for Trapped Ion Quantum Computing and Molecular Sensing (2018)

Photonic integrated circuits for UV and visible light offer a scalable approach to the classical optics and electronics required for large-scale atomic quantum information processing as well as for self-contained lab-on-a-chip systems for molecular diagnostics.
Signatures of carrier-wave Rabi flopping in GaAs (2002)

Summary form only given. Illuminating a semiconductor with a constant light intensity can lead to a periodic oscillation of the inversion, a phenomenon which is known as Rabi flopping. Using pulsed excitation, Rabi flopping has been observed on semiconductors and exhibited periods in the range from 100 fs to 1 ps. Hughes (Phys. Rev. Lett. vol. 81, p. 3363, 1998) theoretically investigated the question of what happens when the light intensity becomes so high that the period of one Rabi oscillation becomes comparable with that of only one cycle of light, 2.7 fs for the band edge of GaAs, and predicted a new phenomenon: carrier-wave Rabi flopping. During a carrier-wave Rabi oscillation, the optical polarization becomes strongly distorted, which can lead to a double-peak structure (the Fourier-transform of the Rabi oscillation) in the third-harmonic (3/spl omega/) spectra. This characteristic shape is quite different from the well-known off-resonant third-harmonic generation. Importantly, resonant effects contain information on the dynamics of electronic resonances-potentially on the timescale of a single optical cycle. It is clear that, under these conditions, the usual envelope approximation breaks down, i.e. both the rotating wave approximation (RWA) as well as the slowly varying envelope approximation (SVEA) must not be used. This paper investigates carrier-wave Rabi flopping experimentally.
Incidence du stockage sur l'évolution du potentiel de collage des cotons (1993)

Afin de préciser l'éventuelle incidence du stockage sur l'évolution du potentiel de collage d'origine entomologique des cotons, deux études ont été mises en oeuvre. La première a été réalisée sur dix neuf cotons stockés pendant deux ans et demi dans des conditions stables d'humidité relative et de température (55 à 60% d'humidité relative et de 21 à 23¼C). La seconde sur vingt et un cotons stockés pendant la même durée dans des conditions ambiantes fluctuantes (30 à 70% d'humidité relative et 18 à 30¼C). Contrairement à une idée couramment répandue, aucune diminution significative du potentiel de collage, mesuré au thermodétecteur, n'a pu être mise en évidence
Residual stress stability of HFMI-treated transverse attachments under variable amplitude loading with the P(1/3) and the linear spectrum (2023)

Abstract The potential of HFMI treatment to increase fatigue life under service loading remains in debate. However, some recent studies show that even under variable amplitude loading (VAL), fatigue strength is increased compared to untreated welds. Discussions generally focus on the stability of initial compressive residual stresses, which may be reduced during VAL due to high peak stresses. In this context, the potential of HFMI treatment is often only attributed to residual stress stability. This study presents further results on the effect of VAL with a P(1/3) and a linear load spectrum on the residual stress stability of HFMI-treated transverse stiffeners (TS) made of mild steel (S355) and high-strength steel (S700M). The impact of random, High-Low and Low-High loading sequences on the fatigue strength as well as on the residual stress behaviour of HFMI-treated joints will be discussed.
Aggregation kinetics in salt‐induced protein precipitation (1989)

Abstract The kinetics of protein aggregation in salt‐induced precipitation processes were studied as a function of salt type, salt concentration, temperature and protein concentration. α‐chymotrypsin (αCT) was used as a model protein. Stopped‐flow turbidimetry was used to monitor the progress of precipitations. Analysis of the linear portions of the turbidity trajectories indicates that temperature and salt concentration effects are related to protein solubility; the protein concentration dependence is well described by the Smoluchowski collision equation. The aggregation kinetics of partially‐inhibited αCT exhibit poisoning behavior, underscoring the importance of dimerization and monomer addition in the precipitation of αCT. Solute particle radius distributions determined via dynamic laser light scattering for low salt and supernatant αCT solutions indicated that significant aggregation does not occur in the absence of supersaturation. A detailed population balance model was proposed that accounted for specific and nonspecific interactions and monomer addition. The model is expected to find general application to protein aggregation phenomena, in particular for proteins that have specific quaternary interactions.
Pyrrolo[1,2-<i>a</i>]quinoxalines: Novel Synthesis via Annulation of 2-Alkylquinoxalines (2012)

In an attempt to synthesize a novel homoleptic complex 3 from 2-methyl-3-phenylquinoxaline 1 and Ir(acac)(3) for application as a triplet emitter in OLEDs (organic light-emitting diodes) no cyclometalation was observed. Instead, an annulation to 1-methyl-4-phenylpyrrolo[1,2-a]quinoxaline 2 was observed. Since pyrroloquinoxalines are potentially bioactive and few paths for their synthesis are known, selected reactions and conditions were investigated, suggesting Ir(acac)(3) as catalyst and proving glycerol to be a reactant.
Stripline coupling to Josephson oscillators (1975)

The observation and analysis of self-induced steps in the current-voltage characteristics of superconducting quantum interference bridges, strongly coupled to superconducting microstrip cavities, are reported. A two-fluid model is used to analyze the results and estimate the amplitude of the oscillating supercurrent in the GHz range as a function of critical current.
Deposition of Cl‐doped CdTe polycrystalline films by close‐spaced sublimation (2015)

Abstract The effects of Cl‐doping on the CdTe layers by the close‐spaced sublimation (CSS) deposition were investigated. Cl‐doped CdTe polycrystalline films were deposited on graphite substrates by CSS method using a mixture of CdTe and CdCl 2 powder as a source. In X‐ray diffraction (XRD) patterns of the obtained films with various deposition times, many diffraction peaks other than CdTe peaks were observed in the deposition times lower than 10 min. These diffraction peaks were probably due to the formation of chlorides of Cd, Te and C, such as CdCl 2 , TeCl 4 , Te 3 Cl 2 and C 10 Cl 8 . X‐ray fluorescence (XRF) and secondary ion mass spectrometry (SIMS) analyses revealed that a large amount of chlorine was contained in the films with the deposition times lower than 10 min, and that Cl concentration decreased with increasing the deposition time above 3 min. These results indicate that the films containing the chlorides of Cd, Te and C in addition to CdTe are formed in the initial stage of the CSS deposition using a mixture of CdTe and CdCl 2 powder as a source. Cross‐sectional images revealed that the grain size was decreased by the effect of Cl‐doping. Furthermore, current‐voltage ( I ‐ V ) characteristics of the CdTe/graphite structures were measured, and it was found that the resistivity of the Cl‐doped CdTe layer was much higher than that of the undoped CdTe layer.

Properties of an ordered ring structure formed by recombinant Treponema pallidum surface antigen 4D (1986)

Ultrastructural and biochemical studies of a recombinant Treponema pallidum surface antigen designated 4D have been conducted due to its likely biological significance. Electron microscopy demonstrated that the 190-kilodalton (kDa) 4D molecule is an ordered ring structure of 10-nm diameter. The 90-kDa proteinase K-treated 4D is an ordered ring structure of 6-nm diameter. Evidence is presented that the 190-kDa ordered ring is maintained by noncovalent bonds; 19-kDa monomers can reassociate in vitro to reform a 190-kDa molecule. Amino acid composition analysis of 190-kDa 4D showed that the molecule is composed of 45% hydrophobic residues. Evidence relating the structure of the 4D ordered ring to its potential role in the pathogenesis of syphilis is discussed.
Acoustical imaging evaluation of thin metal-metal adhesive bonds (2003)

The problem of developing reliable ultrasonic imaging method for characterization of the structural integrity of adhesive bonds in the joints of two thin metal sheets in automotive and aerospace industry is discussed. Mismatch of acoustical impedances and reverberation lead to appearance of long-time complex vibration. Significant attenuation in the adhesive layer also brings difficulties. A new approach, based on convolution filtering of the received signal is represented for the case of sound penetration through a three-layer structure. The experiments were performed with plane and spherically focused acoustic beams in pulse-echo mode in the frequency range of 3-15 MHz. Acoustical images of basic types of defects in real industrial samples are represented and discussed.
