Personalized Kirigami Strain Sensors for in vivo Applications

open access: yesAdvanced Intelligent Systems, EarlyView.
Rapid prototyping of strain sensors is demonstrated using a laser cutter that both converts carbon‐based material to strain responsible graphene and generates cuts in a kirigami‐style pattern that allows enhanced substrate flexibility. This method is used to generate wearable sensors for monitoring heart rate, limb/finger motion, and abdominal ...

Smart Electronic Device-Based Monitoring of SAR and Temperature Variations in Indoor Human Tissue Interaction

open access: yesApplied Sciences
The daily use of devices generating electric and magnetic fields has led to potential human overexposure in home and work environments. This paper assesses the possible effects of electric fields on human health at low and high frequencies.

A hybrid bat algorithm [PDF]

open access: yesarXiv, 2013
Swarm intelligence is a very powerful technique to be used for optimization purposes. In this paper we present a new swarm intelligence algorithm, based on the bat algorithm. The Bat algorithm is hybridized with differential evolution strategies.

Pythagoras at the Bat

open access: yes, 2014
The Pythagorean formula is one of the most popular ways to measure the true ability of a team. It is very easy to use, estimating a team's winning percentage from the runs they score and allow. This data is readily available on standings pages; no computationally intensive simulations are needed.

Flight of the Future: An Experimental Analysis of Event‐Based Vision for Online Perception Onboard Flapping‐Wing Robots

open access: yesAdvanced Intelligent Systems, EarlyView.
A thorough analysis of event‐based vision for flapping‐wing robots is presented, with emphasis on hardware integration, suitability under challenging flight conditions, and real‐time performance. Theoretical and experimental studies demonstrate how these sensors enable robust and efficient onboard perception for ornithopters, thereby advancing autonomy

A Behavioral Test of Contamination Fear in Excessive Health Anxiety [PDF]

open access: yes, 2012
Hypochondriasis and health anxiety are characterized by preoccupation with the fear of currently having a serious physical illness. The Diagnostic and Statistical Manual of Mental Disorders conceptualization of hypochondriasis does not include ...

Baseband version of the bat-inspired spectrogram correlation and transformation receiver [PDF]

open access: yes, 2016
Echolocating bats have evolved an excellent ability to detect and discriminate targets in highly challenging environments. They have had more than 50 million years of evolution to optimise their echolocation system with respect to their surrounding ...

Bats, Bat-Borne Viruses, and Environmental Changes

open access: yes, 2018
During the past decade, bats were shown to a major source for new viruses. Among them are well known coronaviruses such as SRAS or MERS but also Ebola. At the same time, no direct infection from bat to human has been demonstrated. The dynamic of transmission of bat-borne viruses is therefore a complex process involving both sylvatic and urban cycles ...

The spatial distribution of a hummingbird‐pollinated plant is not strongly influenced by hummingbird abundance

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Many angiosperms have evolved specialized systems that promote pollination by specific taxa. Therefore, plant distributions may be limited by the local abundance of their specialist pollinators. In eastern North America, Lobelia cardinalis is thought to be pollinated solely by Archilochus colubris, the only hummingbird species found in
