Time as It Could Be Measured in Artificial Living Systems [PDF]

open access: yes, 2017
Being able to measure time, whether directly or indirectly, is a significant advantage for an organism. It permits it to predict regular events, and prepare for them on time. Thus, clocks are ubiquitous in biology.

Molecular analysis of Anaplasma ovis, Theileria ovis and Brucella abortus in adult Ornithodoros lahorensis soft ticks (Acari: Ixodida: Argasidae) isolated from the Xinjiang Uygur Autonomous Region, China

open access: yesJournal of Veterinary Research
Ticks are obligate blood-feeding arthropods that cause significant economic losses in domestic animal husbandry and threaten public health. However, information about soft ticks (Acari: Argasidae) and tick-borne pathogens in the Xinjiang Uygur Autonomous

Viscoelasticity, Lubricity, and Wear Prevention of Cross‐Linked Mucin Gels

open access: yesAdvanced Materials Interfaces, EarlyView.
Physiologically, biolubrication by mucus reduces friction and protects tissues from tribological stress, with mucins playing a key role. This study compares mucin‐based gels with distinct crosslinking architectures to explore their effect on the lubrication and wear prevention abilities of reconstituted mucin gels.

The First Fermi-LAT SNR Catalog SNR and Cosmic Ray Implications

open access: yes, 2015
Galactic cosmic ray (CRs) sources, classically proposed to be Supernova Remnants (SNRs), must meet the energetic particle content required by direct measurements of high energy CRs.

Impact of life stage-dependent dispersal on the colonization dynamics of host patches by ticks and tick-borne infectious agents

open access: yesParasites & Vectors, 2017
Background When colonization and gene flow depend on host-mediated dispersal, a key factor affecting vector dispersal potential is the time spent on the host for the blood meal, a characteristic that can vary strongly among life history stages. Using a 2-

An Injection‐Molded Modified Silicone Rubber for Cancer‐on‐Chip Applications

open access: yesAdvanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.
This study describes the characterization and application of an injection‐molded functionalized PDMS fluidic insert for the commercially available Micronit system. Modified PDMS can accommodate cell culture and is able to covalently bind proteins for long‐lasting coatings under flow‐conditions.

Adaptive Elastin‐Like Hydrogel with Unidirectional and Controllable Anisotropic Actuation for Soft Robotics and Tissue Engineering

open access: yesAdvanced Materials Technologies, EarlyView.
Fiber‐reinforced elastin‐like tubular scaffolds are engineered to achieve anisotropic and reversible actuation under external stimuli. By adjusting fiber's angle, actuation behavior is finely tuned, enabling distinct actuation responses, even within different regions of the same scaffold.

Synchronizing a modular robot colony for cooperative tasks based on intrainter robot communications [PDF]

open access: yes, 2011
The implementation of robotic cooperative tasks such as pushing an object toward a desired destination or manipulating an object using mobile robots or robotic arms requires motion coordination between the robot colony. When a robot is built by the union

First record of Ornithodoros faccinii (Acari: Argasidae) on toads of genus Rhinella (Anura: Bufonidae) in Brazil

open access: yesRevista Brasileira de Parasitologia Veterinária, 2018
Although a group of soft ticks (Argasidae) associated with amphibians was recently discovered in Brazilian rainforests, parasitism by these ticks on cold-blooded animals remains less common than on mammal and bird species.

Intelligent Eye Tracker Integrated with Cylindrical Capacitive Sensors for Chronic Fatigue Assessment

open access: yesAdvanced Sensor Research, EarlyView.
A wearable capacitive eye tracker for chronic fatigue assessment is presented, utilizing cylindrically shaped capacitive sensors made of a carbon nanotube‐paper composite. By integrating a novel fatigue‐induction protocol with machine learning, the device achieves 0.75‐sensitivity and 0.73‐specificity, providing a practical alternative to existing ...
