Epitaxial Ba-Hexaferrite Films Prepared by Pulsed Laser Deposition (1998)

BaFe12O19 epitaxial hexaferrite films were prepared on c-plane (0001) sapphire substrates by pulsed laser deposition at various substrate temperatures and oxygen atmosphere pressures. Physical properties of the films such as their crystal structure, surface morphology, magnetization, and magneto-optics were evaluated. It was found that the epitaxial films with highly crystallographical quality could be prepared at a substrate temperature of 780°C and an oxygen atmosphere pressure of 200 mTorr. The saturation magnetization Ms and uniaxial anisotropy constants Ku were determined to be about 350 G and 3.0 × 106 erg/cc, respectively, which are close to the values for the bulk material.
Multi-Scale Characterization of Electronic and Ionic Limitations to Power Performance of Composite Electrodes Toward Ultra-High Surface Capacities (2016)

By using a set of advanced techniques such as the broad band dielectric spectroscopy, X-Ray and FIB-SEM computed tomography, it will be described which factor(s) (material properties, engineering parameters) mainly influence the rate discharging behavior of NMC- or LFP-based composite electrodes. This fundamental understanding will be rationalized to disclose ultra-high surface capacities electrodes (more than 10 mAh / cm²) with reasonable rate performance.
Poled PVDF-TrFE coatings on quartz microbalance sensors: A new technique for study of proteins in solution (2011)

This work reports on a novel advanced method of studying proteins in solutions. Superior sensitivity can be achieved by treating the surface of the quartz crystals in such a way as to attract or repel materials based upon their electrical charge. Protein solutions are especially interesting because the net charge of the protein molecule can be changed from positive to negative by varying the pH of the solution around the isoelectric point.

Field Trial of a Novel Non-Intrusive Method for In-Service PMD Measurements in Fiber-Optic Networks (2012)

We have tested a non-intrusive PMD measurement method which monitors and analyzes the in-band high-resolution frequency-dependence in the polarization states of traffic signals. The method is applicable to single-polarization optical signals with arbitrary modulation format.
Radar 3D monitoring of wake-vortex hazards, circulation and EDR retrieval/calibration (2014)

At airports, runway operation is the limiting factor for the overall throughput; specifically the fixed and overly conservative ICAO wake turbulence separation minima. The wake turbulence hazardous flows can dissipate quicker because of decay due to air turbulence or be transported out of the way on oncoming traffic by cross-wind, yet wake turbulence separation minima do not take into account wind conditions. Indeed, for safety reasons, most airports assume a worst-case scenario and use conservative separations; the interval between aircraft taking off or landing therefore often amounts to several minutes. However, with the aid of accurate wind data and precise measurements of wake vortex by radar sensors, more efficient intervals can be set, particularly when weather conditions are stable. Depending on traffic volume, these adjustments can generate capacity gains, which have major commercial benefits. This paper presents Electronic scanning radar trials as Safety Net of a wake turbulence system supporting increased throughput as part of the European ATM research program SESAR, and complementary study UFO (Ultra-Fast wind sensOrs for wake-vortex hazards mitigation) funded by European FP7 program, on Radar EDR retrieval & Calibration.
Closing the Loop on Cognitive Radar for Spectrum Sharing (2021)

We investigate three emerging topics essential for the development of cognitive radar (CR) for spectrum sharing: the response time (RT) of the CR, the autonomous regulation of the perception-action cycle (PAC), and the regulation of cognition. The RT measures the latency of all algorithms/hardware and is examined with respect to enabling capabilities of software-defined systems for rapid flexibility and responsiveness. The autonomous regulation of the PAC determines “how fast the CR can interact with the environment” as well as “how fast the CR should interact with the environment.” The regulation of the PAC is explored with respect to pulse-to-pulse waveform agility to coexist successfully with dynamic radio frequency emitters in the ambient electromagnetic environment (EME) and the consequence of modifying the waveform within the coherent processing interval. Finally, the regulation of cognition determines how to select a particular CR technique appropriately for a given dynamic environment. This selection requires a high level, or metadecision process to identify the appropriate CR technique as the EME changes over time and we therefore concentrate discussion on the newly emerging topic for radar called metacognitive radar. The exploration of these three topics include a review of past and current research with discussion of possible future research.

Modeling negative feedback in single-photon avalanche diodes (2010)

Recently, considerable attention has been placed upon exploiting the negative-feedback effect in accelerating the quenching time of the avalanche current in passively quenched single-photon avalanche-diode (SPAD) circuits. Reducing the quenching time results in a reduction in the total charge generated in the SPAD, thereby reducing the number of trapped carries; this, in turn, can lead to improved after-pulsing characteristics. A passively quenched SPAD circuit consists of a DC source connected to the SPAD, to provide the reverse bias, and a series load resistor. Upon a photon-generated electron-hole pair triggering an avalanche breakdown, current through the diode and the load resistor rises quickly reaching a steady state value, after which it can collapse (quench) at a stochastic time. In this paper we review recent analytical and Monte-Carlo based models for the quenching time. In addition, results on the statistics of the quenching time and the avalanche pulse duration of SPADs with arbitrary time-variant field across the multiplication region are presented. The calculations of the statistics of the avalanche pulse duration use the dead-space multiplication theory (DSMT) to determine the probability of the avalanche pulse to quench by time t after the instant s at which the electron-hole pair that triggers the avalanche was created. In the analytical and Monte-Carlo based models for the quenching time, the dynamic negative feedback, which is due to the dynamic voltage drop across the load resistor, is taken into account. In addition, in the Monte-Carlo simulations the stochastic nature of the avalanche current is also considered.

In Situ Formation of Li3P Layer Enables Fast Li+ Conduction across Li/Solid Polymer Electrolyte Interface (2020)

Abstract Solid‐state polymer electrolytes provide better flexibility and electrode contact than their ceramic counterparts, making them a worthwhile pursuit for all‐solid‐state lithium‐metal batteries. However, their large Li/solid state electrolyte interfacial resistance, small critical current density, and rapid lithium dendrite growth during cycling still limit their viability. Owing to these restrictions, all‐solid‐state cells with solid polymer electrolytes must be cycled above room‐temperature and with a small current density. These problems can be mitigated with an in situ formed artificial solid electrolyte interphase that rapidly conducts Li + ions. Herein, a Li 3 P layer formed in situ at the Li‐metal/solid polymer electrolyte interphase is reported that significantly reduces the electrode/electrolyte interfacial resistance. Additionally, this layer increases the wettability of the solid polymer by the metallic lithium anode, allowing for the critical current density of lithium symmetric cells to be doubled by homogenizing the current density at the interface. All‐solid‐state Li/Li symmetric cells and Li/LiFePO 4 cells with the Li 3 P layer show improved cycling performance with a high current density.

Pressing of porous bodies made of MR wire material (2020)

The paper presents a solution to the problem of determining the basic equation for pressing of porous bodies made of MR material that relates not only the molding pressure to the MR density, but also other physical parameters, including the technological parameters of blank formation. The paper outlines the basic assumptions of the theory of compression molding of items made of MR fibrous material. It has been proved that the ideal process of pressing porous bodies contains two stages for a range of relative densities [0,15; 0,7]. The basic equation of pressing of MR products was determined. It was proved that the equations of ideal pressing (in the absence of external friction forces) have the form of power-law dependences of the molding pressure on the density of the porous body. The power function of hardening of the wire material in the press was obtained. An experimental test of the hypotheses put forward and the assumptions made was carried out, which showed their validity. The obtained theory of axisymmetric pressing of fiber bodies and the obtained basic equation for pressing the MR material can be extended to various types of pressing modes and product shapes. The results of the performed theoretical and experimental studies, as well as their generalization, can serve as a basis for studying mass molding of porous bodies made of fiber materials, taking into account the uneven distribution of density over the volume.
Salt Effect on the Viscosity of Semidilute Polyelectrolyte Solutions: Sodium Polystyrenesulfonate (2023)

We studied the viscosity of semidilute aqueous solutions of sodium polystyrenesulfonate as a function of polymer and salt concentrations. The viscosity data were quantified by applying a scaling relationship between solution correlation length ξ = lgν/B and number of monomers g per correlation volume for chains with monomer projection length l. The specific values Bpe,Bg, and Bth of the B-parameter corresponding to exponents ν = 1, 0.588, and 0.5 were determined by the fraction of charged monomers and their degree of ionization, the effective solvent quality for the polymer backbone, the chain Kuhn length, and the type and strength of monomer–solvent interactions. The values of the B-parameters were obtained from the plateaus of normalized specific viscosity ηsp(c)/Nw(cl3)1/(3ν–1) as a function of the monomer concentration c for polyelectrolytes with weight-average degree of polymerization Nw. The extension of this approach to the entangled solution regime allowed us to determine the packing number of a chain of correlation blobs, P̃e, which completes the set of parameters {Bpe, Bg, Bth, P̃e} uniquely describing static and dynamic properties of polyelectrolyte solutions. This information was used to construct a diagram of states, calculate the fraction of free counterions and the energy of the electrostatic blobs, and establish a crossover concentration to the entangled solution regime.
ACCESSING REPLICATED DATA IN A LARGE-SCALE DISTRIBUTED SYSTEM (M.S. Thesis) (1991)

Many distributed applications use replicated data to improve the availability of the data, and to improve access latency by locating copies of the data near to their use. This thesis presents a new family of communication protocols, called *quorum multicasts*, that provide efficient communication services for replicated data. Quorum multicasts are similar to ordinary multicasts, which deliver a message to a set of destinations. The new protocols extend this model by allowing delivery to a subset of the destinations, selected according to distance or expected data currency. These protocols provide well-defined failure semantics, and can distinguish between communication failure and replica failure with high probability. The thesis includes a performance evaluation of three quorum multicast protocols. This required taking several measurements of the Internet to determine distributions for communication latency and failure. The results indicate that the behavior of recent messages is a useful predictor for the performance of the next. A simulation study of quorum multicasts, based on the Internet measurements, shows that these protocols provide low latency and require few messages. A second study that measured a test application running at several sites confirmed these results.
300-GHz-band wireless communication using a low phase noise photonic source (2020)

Abstract The implementation of advanced multi-level modulation schemes such as quadrature phase-shift keying (QPSK) in contrast to the conventional on–off keying is crucial to further boost the terahertz (THz) communications speed. Thereby, carrier phase noise reduction in the THz range is one of the key goals that need to be urgently achieved. In this paper, the photonic-based THz sources and the phase noise problem are briefly summarized. Then, a low phase-noise photonic source based on the stimulated Brillouin scattering (SBS) optical fiber cavity is first applied for a 300-GHz-band QPSK wireless communication link. The highest data rate at forward-error-correction limited condition was 15 Gbaud utilizing the SBS-based photonic source with a small transmit power of ~ −36 dBm. Its transmission characteristics are evaluated and compared with the conventional optical frequency comb generator (OFCG)-based source at 5 Gbaud. The proposed SBS-based photonic source has been proven to offer better performances than the OFCG-based source with respect to the phase noise, optical carrier to noise ratio, and bit error rate in communications.
An eikonal-based offset-to-angle transform for VSP walkaway data (2016)

Walkaway vertical seismic profile (VSP) reflection amplitude data has the potential to help characterize subsurface formations with higher resolution and lesser uncertainty, as compared to surface seismic data. Placing receivers closer to the target enables seismic data collected in VSP walkaway surveys to be less distorted by wave propagation effects. However, the analysis of amplitude information for rock property estimates requires that the offset domain data be transformed to generate angle gathers. Angle gathers collect the energy in the seismic data to simulate what may have been observed had the data been collected at specific reflection angles. This work describes an algorithm developed for this purpose, based on Kirchhoff depth migration principles. The method was applied to synthetic data to demonstrate its effectiveness. Accurate angle gathers generated by using the algorithm can help to provide additional constraints on subsurface characterization problems.

Localization of the 5′ terminus of late SV40 mRNA (1978)

A cap-containing oligonucleotide has been isolated from a T1 ribonuclease hydrolysate of total Simian Virus 40-specific late RNA and its structure has been determined as 7mG(5')ppp(5') mAmpU(m)pUp(Up,Cp)ApGp. This oligonucleotide constitutes the major 5' terminus of both late mRNA species, 16S and 19S. Assuming that viral mRNA "caps" are derived from a 5'-terminal triphosphate or diphosphate, these results mean that late transcription is (mainly) initiated at nucleotide L 308 (numbering system of Simian Virus 40 DNA, cf. Fiers et al. (1978) Nature, 273, 113-120). The cap is followed by a contiguous leader sequence which is at least 194 nucleotides long.
Effect of hyperthermia on PDT and imaging (2009)

Photodynamic Therapy (PDT) is emerging as a successful tool to treat both malignant and benign tumors. It involves the interaction of a photosensitizer which upon activation by the appropriate light dose, leads to a cytotoxic and vasculotoxic photodynamic reaction. Improvements in PDT in areas such as the delivery and selectivity of photosensitizers, light-delivery and overall efficacy have helped to increase its attractiveness as an option for therapy. For optimizing the PDT treatment by a "see and treat approach," we have developed a number of tumor avid photosensitizers (PS) namely HPPH-Cyanine dye conjugates or other compounds (Iodinated photosensitizers) which have the ability for Optical and/or PET imaging as well as being effective photosensitizers for treatment. Hyperthermia refers to various techniques of heat application which may be delivered as a single modality or as part of an adjunct treatment option to the existing cancer therapies. Depending upon the temperature range used, hyperthermia might either directly induce cell kill or enhance the efficacy of other treatment modalities. Hyperthermia increases blood flow within the body, which may allow for higher dose delivery of photosensitizers with subsequent increased therapeutic efficacy of PDT. Hyperthermia could also increase the sensitivity of molecular imaging. The use of multifunctional photosensitizers for imaging and PDT is an emerging area and we have developed a few such agents in our lab. We wish to explore the use of hyperthermia to improve the use of such multifunctional photosensitizers from the point of view of imaging and/or therapy. Hyperthermia can be performed either as a whole-body mode or as localized mode. Our goal is to see which of the two heating modalities offers us better outcome.
Sortases, Surface Proteins, and Their Roles inStaphylococcus aureusDisease and Vaccine Development (2019)

Prior to bacterial genome sequencing and the genetic analysis of pathogenesis, microbiologists identified molecules on microbial surfaces and studied their role in disease processes (1). The ultimate goal of this research was the identification of molecular formulations inciting antibody responses in vaccine recipients that prevented disease yet would otherwise not cause harm (2). Oswald Avery's discovery of the pneumococcus capsule and the demonstration that capsular polysaccharide vaccine protects against pneumococcal pneumonia represent an important paradigm (3, 4). Another was Rebecca Lancefield's characterization of M protein as the determinant of type-specific immunity against Streptococcus pyogenes, the causative agent of streptococcal pharyngitis and rheumatic fever (2). Lancefield and Sjöquist required proteases or peptidoglycan (murein) hydrolases, but not membrane detergents, to solubilize surface proteins of Gram-positive bacteria (2, 5, 6). The underlying reason for this biochemical phenomenon is that surface proteins are covalently linked to peptidoglycan at their C-terminal ends (7, 8).
