Interpolating sequences for H∞(BH)
No full textWe prove that under the extended Carleson’s condition, a sequence (xn) ⊂ BH is linear interpolating for H∞(BH) for an infinite dimensional Hilbert space H. In particular, we construct the interpolating functions for each sequence and find a bound for the constant of interpolation.The author is supported by Project MTM 2011-22457 (Ministerio de Economía y Competitividad, Spain) and Project P1-1B2014-35 (Universitat Jaume I, Spain

Evaluation and ranking of researchers--Bh Index.
No full textEvaluation and ranking of every author is very crucial as it is widely used to evaluate the performance of the researcher. This article proposes a new method, called Bh-Index, to evaluate the researchers based on the publications and citations. The method is built on h-Index and only the h-core articles are taken into consideration. The method assigns value additions to those articles that receive significantly high citations in comparison to the h-Index of the researcher. It provides a wide range of values for a given h-Index and effective evaluation even for a short period. Use of Bh-Index along with the h-Index gives a powerful tool to evaluate the researchers
ROVIBRATIONAL CHARACTERIZATION OF X BH BY THE EXTRAPOLATION OF PHOTOSELECTED HIGH-RYDBERG SERIES IN BH
No full textAuthor Institution: Department of Chemistry, Purdue University, West Lafayette, IN 47907; Department of Chemistry, University of British Columbia, 6174 University Boulevard,; Vancouver, BC, Canada V6T 1Z3Optical-optical-optical triple resonance spectroscopy of BH isolates high-Rydberg states that form series converging to rotational state specific ionization potentials in the vibrational levels of BH from through . Limits defined by a comprehensive fit of these series to state-detailed thresholds yield rovibrational constants describing the X state of BH. The data provide a first determination of the vibration-rotation interaction parameter cm and a more accurate estimate of cm together with the higher-order anharmonic terms cm and cm. The deperturbation and global fit of series to state-detailed limits also yields a precise value of the adiabatic ionization potential of BH of cm, or eV. High precision is afforded here by the use of graphical analysis techniques, narrow bandwidth laser systems, and an analysis of newly observed, high-principal quantum number Rydberg states that conform well with a Hund's case (d) electron-core coupling limit
More on finite groups with few defining relations
No full textMennicke J, Neumann BH. More on finite groups with few defining relations. Journal of the Australian Mathematical Society. 1989;46(1):132-136.Certain central products of the binary polyhedral groups with finite cyclic groups are here shown to have presentations with two generators and two defining relations; this disproves a conjecture of the second author, stated in J. Austral. Math. Soc. Ser. A 38 (1985), 230–240
COLLISION-INDUCED ELECTRONIC QUENCHING OF
No full textAuthor Institution: Applied Research Corporation; Chemistry Division, Code 6111, Naval Research LaboratoryElectronic quenching cross sections of BH were measured by examining fluorescence decay times in the presence of sixteen collision partners at 298K. The partners exhibit wide variations in mass, electric dipole moment and higher order moments. Except for the extremely low cross sections measured for He and , values range from 5 to . Of the fourteen remaining partners, eleven are represented moderately well by a multipole attractive force model, two (OCS and ) fall well below the expected cross section and one () has an experimental cross section larger than predicted by this model. A temperature comparison is made for the quenching of by CO at 298K and 473K. The measured rate constant at 473K exhibits a 10\% decrease compared to the 298K value with an uncertainty of 11\%
THE REMPI STUDY OF BH IN THE RANGE OF 368-370NM
No full textAuthor Institution: Dept. of Chemistry, Purdue University; Open Laboratory of Bond-Selective Chemistry, University of Science and Technology of ChinaThe mass-selected resonance-enhanced multi-photon ionization (REMPI) of BH in the spectral range of 368-372 nm has been studied. It is shown that the spectral peaks with ion mass 12, 11 and 10 can be assigned to the one-photon transition of 11BH and 10BH free radicals. With very few REMPI studies on BH, the 2-0 band transitions of A-X for 11BH and 10BH are first observed. By using a 40 K rotational temperature and approximately a 600 K background rotational temperature for BH free radicals, the spectra observed was simulated quite well. The observed isotopic shifts of band between 11BH and 10BH, which is between 11.7 and 13.0 cm-1, are mainly due to the vibrational isotope shifts
Device-Aware Test for Back-Hopping Defects in STT-MRAMs
No full textThe development of Spin-transfer torque magnetic RAM (STT-MRAM) mass production requires high-quality dedicated test solutions, for which understanding and modeling of manufacturing defects of the magnetic tunnel junction (MTJ) is crucial. This paper introduces and characterizes a new defect called Back-Hopping (BH); it also provides its fault models and test solutions. The BH defect causes MTJ state to oscillate during write operations, leading to write failures. The characterization of the defect is carried out based on manufactured MTJ devices. Due to the observed non-linear characteristics, the BH defect cannot be modelled with a linear resistance. Hence, device-aware defect modeling is applied by considering the intrinsic physical mechanisms; the model is then calibrated based on measurement data. Thereafter, the fault modeling and analysis is performed based on circuit-level simulations; new fault primitives/models are derived. These accurately describe the way the STT-MRAM behaves in the presence of BH defect. Finally, dedicated march test and a Design-for-Test solutions are proposed.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Computer EngineeringQuantum & Computer Engineerin
DYNAMICS OF DISSOCIATIVE RECOMBINATION, ELECTRON LOSS AND ISOLATED-CORE PHOTON ABSORPTION IN SINGLE ROVIBRONIC RYDBERG RESONANCES OF BH
No full textAuthor Institution: Department of Chemistry, Purdue University, West Lafayette, IN 47907; Department of Chemistry, University of British Columbia, 6174 University Boulevard,; Vancouver, BC, Canada V6T 1Z3Optical-optical-optical triple resonance spectroscopy isolates transitions to vibrationless Rydberg states with principal quantum numbers from to converging to the lowest ionization threshold of BH. These transitions appear in the excitation spectrum of photoionized B atoms produced by dissociative relaxation of BH Rydberg resonances. We observe a region in the spectra that shows evidence for further step of photoabsorption by the BH core that leaves the quantum numbers of the Rydberg electron unchanged. For a certain range of third-photon excitation frequencies, a strongly allowed AX valence electronic absorption by the ion occurs, for which the initially prepared Rydberg electron acts as a spectator. Using a simple mathematical model in which we allow only transitions vertical in , we show that the interval of for which this A$^{2}\Pi\rangle nl\rangle\leftarrow $X$^{2}\Sigma^{+}\rangle nl\rangle$ isolated-core excitation (ICE) rate exceeds that of the predissociation of $^{11}$BH$^{*}$ depends on the finite linewidths and positions of A features and on the -dependent predissociative lifetimes of BH Rydberg molecules. Despite relatively broad resonance features, final states are found to decay slowly to neutral products, and, above threshold, where predissociation competes with direct ionization, the rate of electron loss exceeds neutral fragmentation by only an order of magnitude. Interference lineshapes observed for purely predissociative Rydberg states match closely with states of the same principal quantum number built on , which yield only the ionic product, BH. We conclude that inelastic cation-electron interactions in BH proceed via coupling to a common continuum which gives rise to neutral and ionic products
