The Indexical Voice: Communication of Personal States and Traits in Humans and Other Primates

open access: yesFrontiers in Psychology, 2021
Many studies of primate vocalization have been undertaken to improve our understanding of the evolution of language. Perhaps, for this reason, investigators have focused on calls that were thought to carry symbolic information about the environment. Here

The Roles of Parasitoid Foraging for Hosts, Food and Mates in the Augmentative Control of Tephritidae

open access: yesInsects, 2012
Ultimately, the success of augmentative fruit fly biological control depends upon the survival, dispersal, attack rate and multi-generational persistence of mass-reared parasitoids in the field.

GNSS based relative navigation for intentional approximation of aircraft

open access: yesAviation, 2015
In aviation, satellite navigation is generally only used to determine the absolute position of aircraft. We show that the signals can also be used for safe relative navigation provided that a data link exists between the two aircraft.

Stealth multiboson signals

open access: yes, 2017
We introduce the `stealth bosons' $S$, light boosted particles with a decay $S \to AA \to q \bar q q \bar q$ into two daughter bosons $A$, which subsequently decay into four quarks that are reconstructed as a single fat jet.

The Signal for Signaling, Found

open access: yesPLoS Pathogens, 2009
An important task in the life of bacteria is to influence their environment, which for commensal, symbiotic, and pathogenic bacteria also includes their hosts. This is done primarily by secreting various sets of proteins (effectors), either simply to the outside environment or directly into host cells.

Separation of Overlapping Linear Frequency Modulated (LFM) Signals Using the Fractional Fourier Transform [PDF]

open access: yes, 2010
Linear frequency modulated (LFM) excitation combined with pulse compression provides an increase in SNR at the receiver. LFM signals are of longer duration than pulsed signals of the same bandwidth; consequently, in many practical situations, maintaining

Signaling hypergraphs [PDF]

open access: yesTrends in Biotechnology, 2014
Signaling pathways function as the information-passing mechanisms of cells. A number of databases with extensive manual curation represent the current knowledge base for signaling pathways. These databases motivate the development of computational approaches for prediction and analysis.
