Inter‐ and intraspecific variation in theropod dinosaur dental microwear and its palaeoecological implications

open access: yesThe Anatomical Record, EarlyView.
Abstract Differences in skull and tooth morphology, stomach contents, and estimated bite force between medium‐to‐large sized (≥100 kg) predatory theropod dinosaurs have long been suspected to correlate with differences in their diets and dietary guilds (e.g., hypercarnivory, piscivory).

Angle inversion based on anti-jamming against deceptive multiple false targets

open access: yesThe Journal of Engineering, 2019
Based on digital radio frequency memory technology, jammers can copy the radar signal multiple times by different time delay and frequency shift to form deceptive multiple false targets.

Distributed watermarking for secure control of microgrids under replay attacks

open access: yes, 2018
The problem of replay attacks in the communication network between Distributed Generation Units (DGUs) of a DC microgrid is examined. The DGUs are regulated through a hierarchical control architecture, and are networked to achieve secondary control ...

Pinocchio's Pupil: Using Eyetracking and Pupil Dilation to Understand Truth Telling and Deception in Sender-Receiver Games [PDF]

open access: yes, 2010
We report experiments on sender-receiver games with an incentive for senders to exaggerate. Subjects "overcommunicate" -- messages are more informative of the true state than they should be, in equilibrium.

Opposing consensus science through scholarly practices: The role of claims maintenance

open access: yesJournal of the Association for Information Science and Technology, EarlyView.
Abstract This study examines how three US‐based communities who oppose consensus science produce and disseminate scholarly‐like artifacts: pro‐life activists, Young Earth Creationists, and Anthropogenic Climate Crisis skeptics. Prior research shows that industry‐ or church‐backed advocacy campaigns often generate claims supported by these communities ...

Repeated intradermal lipopolysaccharide challenge responses in healthy volunteers: Implications for clinical pharmacology studies

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Aim Intradermal application of lipopolysaccharide (LPS), a Toll‐like receptor 4 agonist, induces a local inflammatory response and is used as a human challenge model to evaluate the pharmacodynamics of investigational medicinal products. While currently applied in a single, parallel‐group setting, alternative within‐subject designs involving repeated ...

Injuries in deep time: interpreting competitive behaviours in extinct reptiles via palaeopathology

open access: yesBiological Reviews, EarlyView.
ABSTRACT For over a century, palaeopathology has been used as a tool for understanding evolution, disease in past communities and populations, and to interpret behaviour of extinct taxa. Physical traumas in particular have frequently been the justification for interpretations about aggressive and even competitive behaviours in extinct taxa.

Multifrequency OFDM SAR in Presence of Deception Jamming [PDF]

open access: yesEURASIP Journal on Advances in Signal Processing, 2010
Orthogonal frequency division multiplexing (OFDM) is considered in this paper from the perspective of usage in imaging radar scenarios with deception jamming. OFDM radar signals are inherently multifrequency waveforms, composed of a number of subbands which are orthogonal to each other.

On the Secure and Reconfigurable Multi-Layer Network Design for Critical Information Dissemination in the Internet of Battlefield Things (IoBT)

open access: yes, 2018
The Internet of things (IoT) is revolutionizing the management and control of automated systems leading to a paradigm shift in areas such as smart homes, smart cities, health care, transportation, etc.

Early evolutionary history of the seed

open access: yesBiological Reviews, EarlyView.
ABSTRACT The seed is an essential stage in the life history of gymnospermous and angiospermous plants, facilitating both their survival and dispersal. We reappraise knowledge of the evolutionary history of the gymnospermous seed, from its origin in the late Devonian through to the well‐known end‐Permian extinctions – an interval encompassing the ...
