Extensions to Radio Frequency Fingerprinting
… devices using observations crowdsourced from multiple receivers is examined. Combinations of three types of observations are defined. These are combinations of fingerprinter output, features extracted from multiple signals, and raw observations of multiple signals. Performance is demonstrated, …

Unsupervised query expansion for theme queries by exploration and fusion
… fusion. In the lack of human labels, we combine multiple signals to help select the best expansion candidates and further use rank fusion to generate the final ranking and the new query with discretion. The two modules iteratively improve each other: the rank fusion results provide an estimated …

Modality related effects of face and voice information and the perception of human attractiveness
… of sexual selection is likely to incorporate multiple sources of information that can be used to identify a suitable mate. Utilising multiple signals for sexual selection could be advantageous since together these might limit the chance of mating with a suboptimal partner (Møller & …

Attractive silences in cricket courtship song : mate choice using a short-range signal /
Matings systems using signals for sexual communication have been studied extensively and results commonly suggest that females use these signals for locating males, species-identification, and mate choice. Although numerous mating systems employ multiple signals, research has generally focused on …

Experience sampling methods (ESM) in organizations: a review
… duration was 10.13 days. Among studies that used multiple signals per day (56%), the average was 4.16 signals per day. 54% of studies did not report using incentives, 41% did not use reminders. Longer studies were more likely to provide incentives. Over time, online surveys are rising whereas …

Design and characterization of a UHF diplexer/antenna combination
… of the high volume usage of various wireless signals' spectra, it is desired to design systems that can accept the frequencies of multiple signals. A combination of antenna and diplexers can achieve such functionality. With antennas operating in dual frequency and diplexers which separate the …

Finite Mixture Model Specifications Accommodating Treatment Nonresponse in Experimental Research
… researchers have successfully extracted multiple signals from data streams with Gaussian mixture models, where their use is well matched to accommodate researchers in this predicament. While the mathematics underpinning models in either application remains unchanged, there are stark …

Laboratory and field trials evaluation of transmit delay Diversity applied to DVB-T/H networks
… The use of transmit diversity techniques with multiple antennas have long been proposed to improve the performance and capacity of wireless systems. Transmit diversity exploits the scattering effect inherent in the channel by means of transmitting multiple signals in a controlled manner from …

Simultaneous, Large Multi-Gene Delivery for Implementation of Fluorescent Reporter Spatial Multiplexing to Image Signaling Pathways
… cells using fluorescent proteins. Spectral multiplexing has been attempted by engineering reporters to each have a unique spectrum that does not overlap with other reporters to allow for simultaneous recording of multiple signals in a single physiological cascade. However, the problem with …

Studies on the Histone Methyltransferase G9a
… development and function requires integration of multiple signals, both cell autonomous and receptor-mediated, with complex DNA recombination reactions which are unique to lymphocytes. We have exploited these features to explore the possible functions of histone 3, lysine 3 (H3K9) methylation in …
