The concept of a spectral envelope for exploring the periodic nature of real-valued time series is introduced. This concept follows naturally from the data-dependent approach proposed by Stoffer et al. (1993) for spectral analysis and scaling of categorical processes. Here, the notion of the spectral envelope is applied in the context of transformations of a time series, and a datadependent app...

Immunoglobulin (adsorbed resistance antiserum) reacting specifically with antigens from tetracycline (Tc)-resistant Staphylcoccus aureus or Escherichia coli was produced by adsorbing immunoglobulin against cell envelopes of resistant strains with envelope extracts from the respective isogenic susceptible strains. Adsorbed resistance antiserum against S. aureus reacted with envelope extracts fro...

Loss of control (LOC) occurs when an aircraft motion departs from the typical flight envelope. Loss of control events have been a contributing factor in numerous commercial airline accidents. Hence there has been interest in rigorously defining and quantifying the characteristics of LOC. One major issue is that LOC is rare and hence there is limited flight data for these events. This limits the...

S U M M A R Y We propose a new approach to full seismic waveform inversion on continental and global scales. This is based on the time–frequency transform of both data and synthetic seismograms with the use of timeand frequency-dependent phase and envelope misfits. These misfits allow us to provide a complete quantification of the differences between data and synthetics while separating phase a...

this paper classifies green envelopes as green roofs and green walls according to effective factors, which were derived from literature to compare the green envelopes’ thermal and energy performance in a more effective way. for this purpose, an extensive literature review was carried out by searching keywords in databases and studying related journal papers and articles. the research method for...

background: dengue is a global arboviral threat to humans; causing 390 million infections per year. the availability of safe and effective tetravalent dengue vaccine is a global requirement to prevent epidemics, morbidity, and mortality associated with it. methods: five experimental groups (6 mice per group) each of 5-week-old balb/c mice were immunized with vaccine and placebo (empty plasmid) ...

data envelopment analysis (dea) is a technique for measuring the efficiency of decision making units. in all models of the dea, for each unit under assessment, the numerical efficiency is obtained which may be less than or equal to one. given the possible large number of functional units, we use various ranking methods for evaluating units. one of the rating methods is balance index and topsis....

data envelopment analysis (dea) is a mathematical technique to evaluate the performance of firms with multiple inputs and outputs. in conventional dea models, the efficiency scores of decision making units (dmus) with non-negative inputs and outputs are evaluated in a special period of time. however, in the real world there are situations wherein performance of firms must be evaluated in multip...
