Structural and emission properties of amorphous linear-chain carbon (2012)

The structure of amorphous linear-chain carbon (LCC) during the structure formation under conditions of vacuum annealing was studied by electron diffraction and Raman spectroscopy methods. It was shown that the determining factor of lowering the work function of the LCC coating is the formation of nanoclusters of mutually misoriented short carbon chains.
Perpendicular magnetic tunnel junctions with a synthetic storage or reference layer: A new route towards Pt- and Pd-free junctions (2016)

We report here the development of Pt and Pd-free perpendicular magnetic tunnel junctions (p-MTJ) for STT-MRAM applications. We start by studying a p-MTJ consisting of a bottom synthetic Co/Pt reference layer and a synthetic FeCoB/Ru/FeCoB storage layer covered with an MgO layer. We first investigate the evolution of RKKY coupling with Ru spacer thickness in such a storage layer. The coupling becomes antiferromagnetic above 0.5 nm and its strength decreases monotonously with increasing Ru thickness. This contrasts with the behavior of Co-based systems for which a maximum in interlayer coupling is generally observed around 0.8 nm. A thin Ta insertion below the Ru spacer considerably decreases the coupling energy, without basically changing its variation with Ru thickness. After optimization of the non-magnetic and magnetic layer thicknesses, it appears that such a FeCoB/Ru/FeCoB synthetic storage layer sandwiched between MgO barriers can be made stable enough to actually be used as hard reference layer in single or double magnetic tunnel junctions, the storage layer being now a single soft FeCoB layer. Finally, we realize Pt- or Pd-free robust perpendicular magnetic tunnel junctions, still keeping the advantage of a synthetic reference layer in terms of reduction of stray fields at small pillar sizes.

Optimized excitation sources and exact solutions for ultrasonic field propagation in a nonlinear medium with hysteretic behavior (2005)

Ultrasonic wave propagation in a microhomogeneous material with hysteretic strain-stress behavior was studied by the application of a Lie group algebraic method in order to find optimized excitation sources. Starting from previously published work (V. Gusev, J. Acoust. Soc. Am., vol.107, no.6, p.3047-3058, 2000), the particle velocity of an ultrasonic wave propagating in the nonlinear medium is described, avoiding the absolute term. This algebraic method provides a class of exact solutions for particle velocity in a nonlinear medium.
Numerical comparison of the thermal performance of 3D stacking and Si interposer based packaging concepts (2013)

In this paper, the thermal performance and the thermal die-to-die coupling are compared for the case of a 3D stacked configuration and a Si TSV-interposer by means of detailed thermal finite element simulations. The comparison is applied to packages with two components: 10×10mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> logic chip and a 2×10mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> temperature sensitive SerDes chip. A one-to-one comparison is made for package configurations without heat sink and for packages with integrated heat spreader and high performance heat sink.
Paper #178: Engagement Patterns of the Antrolateral Ligament of the Knee (2017)

We established a new method to characterize the function of secondary stabilizers of the knee as a function of combined rotatory loads by assessing where within the passive envelope of motion each structure began to carry load. The major finding was that the anterolateral ligament consistently engaged (i.e., bore load) beyond the range of coupled anterior translation of the ACL-intact knee.
Accurate Threshold Voltage Measurement for Use with SOISPICE (1995)

The thin-film nature of silicon on insulator (SOI) material complicates considerably the extraction of accurate threshold voltage (VTf) values. This work assesses the accuracy of the standard VTf extraction techniques and presents an alternative method, independent of series resistance, with improved accuracy. The improved accuracy of the threshold voltage measurement enables physical parameters such as flatband voltages and oxide thicknesses to be calculated more accurately. As SOI technology is an important contender for low voltage/low power, high temperature and ULSI circuit applications it is imperative to have an established, accurate modelling facility such as SOISPICE. We show that our method of measuring VTf is compatible with SOISPICE. Simulation results show that using an inappropriate VTf extraction technique can cause significant errors in the transient response of SOI circuits at low voltages.
Integrated multi-drive configuration for starter-alternator applications (2015)

The paper presents a study of an Integrated Multi-Drive (IMD) system, obtained by redesigning the stator winding of a standard electrical machine to derive a combination of several Sub-Machines (SMs). A single SM consists of an independent three-phase stator winding set sharing a common magnetic circuit including the rotor with the other SMs. Exploiting independent vector control for each SMs, the proposed structure can be considered as a complex electromechanical system with newer perspectives compared to standard single-shaft multi-drives systems where the machines are not magnetically coupled. In the paper, a new IMD configuration has been experimentally tested addressing starter-alternator application. Study results highlight the potential and flexibility of proposed integrated IMD to realize an energy conversion process with controllable multidirectional power flows, also providing a satisfying dynamic behavior to the system.
Novel biocatalysts for white biotechnology (2006)

White Biotechnology uses microorganisms and enzymes to manufacture a large variety of chemical products. Therefore, the demand for new and useful biocatalysts is steadily and rapidly increasing. We have developed methods for the isolation of new enzyme genes, constructed novel expression systems, and optimized existing enzymes for biotechnological applications by methods of directed evolution. Furthermore, we have isolated and characterized biocatalysts relevant for the preparation of enantiopure compounds.

Assimilation and transport of nitrogen in rice II. <sup>15</sup>N-labelled nitrate nitrogen (1974)

An investigation was made to study the assimilation and transport of 15N-labelled nitrate nitrogen in rice plant (Oryza sativa L.). Nitrogen from labelled nitrate at the end of plant feeding was found mainly in nitrate form, and was more prevalent in roots, stem and leaf sheaths. The nitrite fraction had the next largest 15N enrichment. The 15NO3 assimilation in the newly emerged panicle was mainly in amide and amino acid. The 15N-incorporation at day 0 was greatest in amino acid and nitrate of roots and decreased towards the stem and leaves. Incorporation in these fractions considerably decreased from day 0 to day 10. Probably most of the nitrogen from the nitrate source was transported from the roots to the shoot in nitrate and amino acid forms. A decrease of 15N-incorporation in the soluble N fraction and increase in the insoluble N fraction from day 0 to day 10 in plant parts, particularly the blades, suggested that protein synthesis occurred mostly in young parts of the shoot during this period. The marked variation in 15N distribution in different parts of the plant during the 10 days indicated that the nitrogen in roots and tillers was probably remobilized and transported to other parts, particularly the upper leaf blades. Ammonium and nitrate nitrogen transport in rice plant are compared.

Hipoglikemia u pacjentów poddanych chirurgii metabolicznej — przegląd literatury (2019)

Bariatric surgery is currently the most effective method of obesity treatment, regardless of the method used. Compared to non-surgical methods, it ensures greater weight reduction and better control of comorbidities, especially type 2 diabetes. The complication of bariatric surgery, both with and without type 2 diabetes, is the presence of a significant decrease in blood glucose level — hypoglycaemia. In the early postoperative phase, it is mainly hypoglycaemia associated with the so-called ‘dumping syndrome’. Later (months or years after the surgery), it is mainly caused by endogenous hyperinsulinism (PBSH, post-bariatric surgery hypoglycaemia). The incidence of PBSH varies considerably, from 0.1–50% depending on the adopted criteria. The pathomechanism of this phenomenon is multifactorial and based, among others, on inadequate incretins secretion, in particular glucagon-like peptide 1, in response to a meal, modified hepatic glucose metabolism or reduction in ghrelin concentration. Due to incomplete understanding about the pathophysiology of this phenomenon, there are no treatment algorithms. Nevertheless, three therapeutic options can be distinguished: diet modification, pharmacotherapy, and surgical treatment.
Cellular and network properties of the subiculum in the pilocarpine model of temporal lobe epilepsy (2005)

The subiculum was recently shown to be crucially involved in the generation of interictal activity in human temporal lobe epilepsy. Using the pilocarpine model of epilepsy, this study examines the anatomical substrates for network hyperexcitability recorded in the subiculum. Regular- and burst-spiking subicular pyramidal cells were stained with fluorescence dyes and reconstructed to analyze seizure-induced alterations of the dendritic and axonal system. In control animals burst-spiking cells outnumbered regular-spiking cells by about two to one. Regular- and burst-spiking cells were characterized by extensive axonal branching and autapse-like contacts, suggesting a high intrinsic connectivity. In addition, subicular axons projecting to CA1 indicate a CA1-subiculum-CA1 circuit. In the subiculum of pilocarpine-treated rats we found an enhanced network excitability characterized by spontaneous rhythmic activity, polysynaptic responses, and all-or-none evoked bursts of action potentials. In pilocarpine-treated rats the subiculum showed cell loss of about 30%. The ratio of regular- and burst-spiking cells was practically inverse as compared to control preparations. A reduced arborization and spine density in the proximal part of the apical dendrites suggests a partial deafferentiation from CA1. In pilocarpine-treated rats no increased axonal outgrowth of pyramidal cells was observed. Hence, axonal sprouting of subicular pyramidal cells is not mandatory for the development of the pathological events. We suggest that pilocarpine-induced seizures cause an unmasking or strengthening of synaptic contacts within the recurrent subicular network.

MIMIC sensor technology for highway vehicle applications: potential and challenges for the future (1995)

Recent advances in MIMIC (MIllimeter Monolithic Integrated Circuit) radar technology play&#13;\nan important role in the development of automated highway systems and automated vehicle&#13;\ncontrol systems. This report presents results of a preliminary investigation into MIMIC-based&#13;\nautomotive radar technology and makes recommendations for hardware evaluation.&#13;\nMIMIC technology integrates much of the radar transmitted, receiver, and signal processing&#13;\nhardware onto a one- or two-piece chip set. Massive integration leads to lower manufacturing&#13;\ncosts and lower product costs. Moreover, this integration reduces the size of hardware,&#13;\nallowing the radar components to be installed in the vehicle without the need for significant&#13;\nmodifications. As radar systems become smaller and cheaper, the demand for these systems&#13;\nwill increase.&#13;\nRadar systems affect both the vehicles so equipped and other vehicles within a reasonable&#13;\nproximity. Before vehicles equipped with radar systems travel on public roads, their effects on&#13;\ntraffic flow and highway safety must be investigated so that proper regulations can be&#13;\ndeveloped and enforced.
Lack of ribosomal protein S1 in Bacillus stearothermophilus. (1976)

The 30S ribosomal subunit of Bacillus stearothermophilus migrated as a single band when electrophoresed on agarose-acrylamide composite gels. The addition of the ribosomal protein S1 purified from Escherichia coli resulted in the appearance of an additional band migrating more slowly; 14C-labeled S1 of E. coli was shown to be associated only with this form. Antibody against E. coli protein S1 did not crossreact with either the total 30S ribosomal proteins or the postribosomal supernatant from B. stearothermophilus. These results indicate that B. stearothermophilus lacks a protein equivalent to E. coli S1 and may explain our previous finding [Eur. J. Biochem. 56, 15-22 (1975) that E. coli S1 greatly stimulated the translation by B. stearothermophilus ribosomes of f2 phage RNA.
Polyplex Formation Influences Release Mechanism of Mono- and Di-Valent Ions from Phosphorylcholine Group Bearing Hydrogels (2014)

The release of monovalent potassium and divalent calcium ions from zwitterionic phosphorylcholine containing poly(2-hydroxyethyl methacrylate) (pHEMA)-based hydrogels was studied and the effects of polymer swelling, ion valence and temperature were investigated. For comparison, ions were loaded during hydrogel formulation or loaded by partitioning following construct synthesis. Using the Koshmeyer-Peppas release model, the apparent diffusion coefficient, Dapp, and diffusional exponents, n, were Dapp (pre-K+) = 2.03 × 10−5, n = 0.4 and Dapp (post-K+) = 1.86 × 10−5, n = 0.33 respectively, indicative of Fickian transport. The Dapp (pre-Ca2+) = 3.90 × 10−6, n = 0.60 and Dapp (post-Ca2+) = 2.85 × 10−6, n = 0.85, respectively, indicative of case II and anomalous transport. Results indicate that divalent cations form cation-polyelectrolyte anion polymer complexes while monovalent ions do not. Temperature dependence of potassium ion release was shown to follow an Arrhenius-type relation with negative apparent activation energy of −19 ± 15 while calcium ion release was temperature independent over the physiologically relevant range (25–45 °C) studied. The negative apparent activation energy may be due to temperature dependent polymer swelling. No effect of polymer swelling on the diffusional exponent or rate constant was found suggesting polymer relaxation occurs independent of polymer swelling.

Growth rates for Pt2Si and PtSi formation under UHV and controlled impurity atmospheres (1980)

Platinum silicides have been prepared by depositing Pt thin films under ultrahigh vacuum (UHV) and controlled impurity atmospheres including a range of O2 partial pressures. The substrates and silicide films were analyzed with Rutherford backscattering spectroscopy (RBS) and Auger electron spectroscopy (AES). Growth of the silicide films was observed under UHV in real time with RBS. Growth rates (i.e. diffusivities) for Pt2Si and PtSi formation were observed to be one to three orders of magnitude higher than previously reported. Increasing partial pressures of O2 during Pt depositions caused the growth rates to decrease by up to a factor of 20 and caused disruption of the normal phase growth sequence; partial pressures of N2 and Ar had no effect.

Laboratory Development and Field Evaluation of a Passive Sampling Device For Monomethylhydrazine in Ambient Air (1994)

A passive sampling method applicable to personnel and area monitoring was developed for the quantitation of monomethylhydrazine (MMH) in ambient air at sub part-per-million levels. The method involves the use of a black, molded, low-density polyethylene sampler consisting of a diffusion barrier and a citric acid collection medium. It collects samples that can be analyzed by NIOSH colorimetric methods or a coulometric titration procedure. The sampler incorporates a two-millimeter thick diffusion barrier with 144 one-millimeter diameter holes and produces a collection rate for MMH of 27 cm3/min. The accuracy of data collected is within 30% of actual values under most conditions. The dosimeter has demonstrated accuracy for sampling periods of 15 min to 66 hours when sampling MMH at the threshold limit value concentration of 200 ppb. Limits of detection are dictated by the specific analytical method. Coulometric titration will detect exposures of 30 ppb-hours. Laboratory tests were conducted in controlled atmospheres to evaluate collection rate, face velocity effects, relative humidity effects, sample stability, reproducibility, linearity, and interference effects of selected chemical vapors. Field tests evaluated performance under typical conditions. Test locations were selected to provide information on probable interferents. A double-blind protocol was used involving industrial hygienists, analytical chemists, and auditors. The data obtained revealed a performance problem not encountered in the laboratory. The cause was identified and the prototype system was modified and retested. Results from the modified sampler show that it is suitable for workplace monitoring applications with two minor interferents: tobacco smoke and intense direct sunlight.
NMR studies of the hydration of biological macromolecules (1996)

The information on the hydration of proteins and nucleic acids in aqueous solution that can be obtained using high resolution nuclear magnetic resonance (NMR) spectroscopy is largely complementary to the information obtained by diffraction experiments with single crystals, which is the only other approach enabling studies of hydration at atomic resolution. The presently discussed NMR studies are primarily focused on the rate processes governing the exchange of water molecules between the bulk solvent and the hydration sites on the biological macromolecules. A novel NMR experiment for observation of protein and nucleic acid hydration is described, and long-time molecular dynamics (MD) simulations used to support the analysis of NMR data on hydration water in the intermolecular interface of protein–DNA complexes are presented.
