Published 1991Staff ViewISSN: 1089-7550Source: AIP Digital ArchiveTopics: PhysicsNotes: Excess low-frequency noise extending to MHz frequencies was observed in dc current biased granular high-Tc thin films. At particular bias conditions random telegraph signal produced by a single, fast two-level fluctuator dominated the noise properties of the sample. Lifetimes of the low- and high-voltage states of the fluctuating system were found to be exponentially distributed. Power spectra of the excess noise signal could be well fitted with a single Lorentzian contribution. Duty cycle dependence of the random telegraph signal on bias conditions was used to get an insight into physical mechanism causing the fluctuations. Charge trapping events in the intergranular intrinsic Josephson junctions and trapped flux hopping were identified as possible alternative sources of the observed noise.Type of Medium: Electronic ResourceURL: -

ISSN: 1089-7550Source: AIP Digital ArchiveTopics: PhysicsNotes: Spectral properties of rf radiation from intrinsic Josephson junctions in high Tc Y-Ba-Cu-O thin film have been measured in the frequency range up to 1.5 GHz. Narrow emission lines with the 3 dB bandwidth of the order of 20 MHz were detected indicating that Josephson clusters radiate coherently. Synchronization conditions are determined by dc current and external magnetic field bias. Frequency locking of radiation to external resonant circuit was also observed. Spectral line narrowing due to resonant lock was distinguished from the coherence-induced narrowing by different tuning properties of the emission line. Noncoherent Josephson radiation manifests itself as a broadband background noise increase. A pronounced 1/f-like tail sensitive to dc bias and magnetic field was observed in a low frequency part of the spectrum.Type of Medium: Electronic ResourceURL: -

Published 2000Staff ViewISSN: 1089-7623Source: AIP Digital ArchiveTopics: PhysicsElectrical Engineering, Measurement and Control TechnologyNotes: A new procedure for analysis of random telegraph signals in time domain has been developed and applied to the analysis of voltage fluctuations in the current induced dissipative state in superconducting thin films. The procedure, based entirely on the difference in the statistical properties of discrete Marcovian telegraph fluctuations and Gaussian background noise, ascribes each point of the experimental time record to one of the telegraph states. The average statistical lifetimes and amplitudes of the telegraph signal are then determined in an iterative way by fitting the amplitude histogram of thus obtained record of the redistributed data to the two-Gaussian histogram of the original experimental signal. The procedure allows for analyzing "noisy" random telegraph signals with low ratio between the signal amplitude and the intensity of the background noise that cannot be analyzed by the classical approach. Separation of the time record into two subrecords relative to two telegraph states also enables in-depth analysis of the spectral properties of the background noise observed together with the telegraph fluctuations. © 2000 American Institute of Physics.Type of Medium: Electronic ResourceURL: -

Published 1988Staff ViewISSN: 1365-2494Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, NutritionNotes: Spring-seeded rape requires approximately two-thirds of the growing season in the north-cast USA, to reach physiological maturity. Harvest frequency studies were conducted with rapes and rape hybrids in Pennsylvania to determine whether forage yields and/or quality can be improved with multiple harvests, and whether cultivars respond similarly to harvest management. Nitrogen was applied at 75 kg ha−1 at seeding and 75 kg ha−1 70 d after seeding. Additional fertilizer was applied according to soil test results. A split-split-block design was used. Harvest frequencies of 180, 90, 60, or 30 d were randomly assigned to blocks. Cultivars were randomized within each harvest frequency, with four replicates. Amount of regrowth of all cultivars after mid-August was highly variable, depending on weather. Foliar diseases and aphids lowered yields in different years. Cultivars differed in susceptibility to diseases and aphids as well as in morphology. Forage yields and crude protein yields of rape generally were highest with the 90-d harvest frequency, whereas crude protein concentration was highest with the 30-d frequency. Mean in vitro dry matter digestibility (IVDMD) values were high regardless of harvest frequency, cuttivar, or sampling date. Yield differences between cultivars generally were greatest with one harvest at 180 d; mean yield was highest for forage rapes, intermediate for winter oil rapes, and lowest for rape x Chinese cabbage hybrids. Under frequent harvesting, BLE rape and the rape x Chinese cabbage hybrid performances were exceptional as regards forage yield and quality.Type of Medium: Electronic ResourceURL: -

Postponing sowing date in south Florida from October to November to January resulted in 150, 130 and 110-d growing seasons respectively. Dry matter (DM) yields of turnip, swede, rape and kale were lowered by each later sowing date and shorter growing season, and crude protein (CP) concentration was the same as for, or was increased by late sowing. In vitro organic matter digestibility (IVOMD) of turnip, swede and rape leaves was not affected by sowing date, but roots of turnip and swede from the earlier sowings and longer growing seasons were more digestible. Yield of the four species depended on harvest management as well as date of sowing and length of growing season. Total yield of turnip and swede were unaffected by harvest management but multiple cutting resulted in greater leaf yields and smaller root yields, whereas stockpiling resulted in smaller leaf yields and larger root yields. Kale produced more DM when harvested once at the end of the winter growing season but rape produced the greatest DM yield when sown in October and harvestedType of Medium: Electronic ResourceURL: -

ISSN: 1089-7550Source: AIP Digital ArchiveTopics: PhysicsNotes: The relation between random telegraph noise and 1/f-type background voltage fluctuations in current biased high-Tc films has been investigated. The experiments have revealed that the telegraph noise in high-Tc superconducting films is due to a combined action of a macroscopic two-level fluctuator and a detector. The macroscopic telegraph signal does not constitute an elementary contribution to 1/f noise. However, the behavior of telegraph and 1/f-like voltage fluctuations have shown astonishing similarities. Telegraph voltage amplitudes and 1/f power spectrum magnitude scale linearly with changing current flow above almost identical threshold currents. The telegraph signal symmetry characteristics have been found to be linear also but with distinctively different offset currents. Analysis of the measured characteristics indicates that the telegraph and 1/f fluctuations are due to different flux fluctuators coupled to observable voltages by the same detector mechanism. © 1996 American Institute of Physics.Type of Medium: Electronic ResourceURL: -

Published 1989Staff ViewISSN: 1077-3118Source: AIP Digital ArchiveTopics: PhysicsNotes: A pronounced X-band microwave noise emission from Y-Ba-Cu-O thin films has been observed. Emission depends strongly on temperture, bias current, and magnetic field. Two types of emission lines can be distinguished in the power versus dc bias spectra. The lines which remain at stable current positions against temperature we tentatively ascribe to the interaction of depinned flux flow with a two-dimensional Josephson junction array. The lines that appear at fixed voltage positions may be attributed to the Josephson radiation of a distributed network of junctions. No significant emission was detected from Bi-Ca-Sr-Cu-O films.Type of Medium: Electronic ResourceURL: -

ISSN: 1077-3118Source: AIP Digital ArchiveTopics: PhysicsNotes: An experimental technique for measuring magnetic fluctuations by means of a double-layer Hall sensor array is described. The technique relies on cross-correlating Hall signals from two independent sensors positioned one above the other in two separate two-dimensional-electron-gas layers of a GaAs/AlGaAs heterostructure. The effectiveness of the technique is demonstrated by a reduction of the magnitude of the background noise floor of the correlated sensors with respect to the noise level of the best single sensor. © 2001 American Institute of Physics.Type of Medium: Electronic ResourceURL: -

The measurements were carried out at various temperatures below and above the ferromagnetic transition temperature TC. It has been found that the dynamic electroresistance exhibits stunning similarities to the colossal magnetoresistance at the corresponding temperatures. The correlation observed between the electric- and magnetic-field effects is attributed to electrically induced magnetoresistance. © 2001 American Institute of Physics.Type of Medium: Electronic ResourceURL: -

Published 1992Staff ViewISSN: 1089-7623Source: AIP Digital ArchiveTopics: PhysicsElectrical Engineering, Measurement and Control TechnologyNotes: Ultrahigh frequency rf-SQUID magnetometer employing a cryogenic preamplifier and a commercially available thin film rf-SQUID sensor have been designed, manufactured, and tested. The system has been operated at 316 MHz, which is the maximum pump frequency accepted by the thin film sensor. The cryogenic preamplifier has been built around a microwave high-electron-mobility transistor which was made unconditionally stable at ultrahigh frequency band by means of an appropriate circuit design, namely, a cascode configuration. The total flux noise of the magnetometer has been found to be 8.4 × 10−6Φ0/(square root of)Hz at 4.2 K and 5.8× 10−6Φ0/(square root of)Hz at 1.4 K. The temperature dependence of the fractional step rise α of the current-voltage rf characteristic has been measured to be proportional to the 2/3 power of the SQUID sensor temperature. The noise performance of the system at 4.2 K has been limited by the intrinsic SQUID noise only, in good agreement with theoretical predictions.Type of Medium: Electronic ResourceURL: -

Published 1993Staff ViewISSN: 1365-3083Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: MedicineNotes: Infection or immunization with measles virus induces a protective immune reaction including neutralizing antibodies against the haemagglutinin and fusion protein. The reactivity of the polyclonal IgG response of sera obtained from late convalescent donors was studied, using overlapping 15mer peptides covering the complete sequence of the measles virus haemagglutinin. Most sera reacted with a similar set of peptides generating a characteristic binding pattern. The reactive peptides correspond to a region mediating cell hemolysis (aa310–325), to regions which serve as targets to neutralizing antibodies and to a putative transmembrane region (aa35–58). The latter region contains also a human T-cell epitope providing evidence of a non-random association of T- and B-cell epitopes. We also immunized different strains of mice and rabbits with measles virus. In contrast to the human sera, animal sera with strong neutralizing activities did not react with any of the H-protein peptides. The mostly weak reactivities with the linear sequences contrast with the strong neutralizing activities of the human or animal antibodies, suggesting that these primarily recognize the fusion protein or conformational epitopes of the haemagglutinin protein.Type of Medium: Electronic ResourceURL: -

Published 2001Staff ViewISSN: 1089-7690Source: AIP Digital ArchiveTopics: PhysicsChemistry and PharmacologyNotes: Fluorescence correlation spectroscopy (FCS) is an important method for investigations of diffusion processes as well as of photophysical properties of fluorescing molecules. It has lately been applied in studies of the photodynamics of the green fluorescent protein (GFP). In this case FCS yields valuable information about the population of dark, non-fluorescing states of the molecule. For three-level systems rate constants into and out of the dark state can easily be determined with FCS. This task however becomes significantly more complex for molecules that possess several dark states. Here we present two-color FCS with simultaneous two-color excitation as a method that also yields spectroscopic information about the dark states. This makes the complete analysis of a molecular four-level system possible. The analysis of the GFP mutant E222Q is given as an example of two-color FCS that is readily applicable to other molecules with photoconvertible dark states. For E222Q we determine all the rate constants within the four-level system. With these data we calculate the population of the different molecular states in bulk experiments as encountered, e.g., in microscopic studies. © 2001 American Institute of Physics.Type of Medium: Electronic ResourceURL: -

Published 1996Staff ViewISSN: 1365-3083Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: MedicineNotes: The induction of antibodies against peptides requires the presence of a T helper cell epitope. In the absence of an added T-cell epitope only 10% of the mice, or less depending on the strain, gave an antibody response to a series of peptides of the measles virus (MV) fusion (F) protein. After co-immunization with a non-covalently coupled T-cell epitope more than 60% of the peptides became immunogenic. Considerable differences became apparent when BALB/c mice were immunized with peptides in the presence of different T-cell epitopes. An immunodominant T-cell epitope of the MV-F protein was more efficient than a subdominant or a cryptic T-cell epitope in providing help to a non-linked B-cell epitope. There is both a ranking order of the amount of help which B-cell epitopes require and a ranking order for the help T-cell epitopes are able to provide. The capability of a T-cell epitope to provide help to a B-cell epitope correlated with its own immunogenicity, i.e. the intensity of the antibody response to the peptide representing the T-cell epitope. The data suggest that for each MHC class II allele there is an optimal T-cell epitope which can provide help to a maximal number of B-cell epitopes and that such a peptide can be identified by its ability to induce antibodies against itself. By using this strategy, the authors were able to induce antibodies which cross-reacted with the MV.Type of Medium: Electronic ResourceURL: -

ISSN: 1365-2494Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, NutritionNotes: Studies were conducted to characterize sward dynamics of lucerne (Medicago sativa L.) and perennial, Italian or short rotation hybrid rye-grass (Lolium perenne L. and L. multiflorum Lam.) binary mixtures under hay management. Lucerne/timothy (Phleum pratense L.) mixtures were included as controls. The study was conducted on two farms in central Pennsylvania, USA on Hagerstown silt loams (fine, mixed, mesic hapludalf). Total dry matter yield, grass yield and yield of digestible dry matter were higher for tetraploid perennial and tetraploid Italian ryegrass mixtures than for timothy mixtures. Seasonal production differed for the three kinds of ryegrass. Italian ryegrass dry matter yields were higher in cuts 2 and 3 than perennial ryegrass yields. Grass yields represented 34%, 24% and 12% of total yields of the Italian, perennial or short rotation, and timothy mixtures, respectively. However, herbage in vitro dry matter digestibility of Italian was lower than that of perennial ryegrass.The tetraploid perennial ryegrasses Grimalda and Reveille had high-ranking N concentrations more frequently than other cultivars, while Bar-vestra and Reveille tetraploid perennials and Bison short rotation ryegrass had high-ranking dry matter digestibility values more frequently than the other cultivars. Perennial ryegrass cultivars and Lipo tetraploid Italian ryegrass persisted well for 4 years and produced higher yields with a lower weed content than timothy mixtures. It is concluded that perennial ryegrasses and Lipo Italian ryegrass should be recommended over timothy, as companion grasses with lucerne.Type of Medium: Electronic ResourceURL:
