A Soft Robotic Device for Targeted Massage Therapy of Residual Limbs

Advanced Robotics Research, EarlyView.
Residual limb edema after amputation can hinder recovery and delay prosthetic fitting. This study presents a soft‐robotic wearable device that delivers sequential compression through pneumatic McKibben actuators. By replicating the principles of manual lymphatic drainage, the device generates controlled mechanotherapeutic pressure patterns, providing a

Site fidelity in predictable and unpredictable habitats

Evolutionary Ecology, 1993
Site fidelity, the tendency to return to a previously occupied location, has been observed in numerous species belonging to at least three phyla. In this paper I develop a general model using dynamic programming to investigate conditions under which fidelity to a previously occupied territory will be advantageous. The results predict that site fidelity

Defining null expectations for animal site fidelity

Ecology Letters, 2022
Abstract Site fidelity—the tendency to return to previously visited locations—is widespread across taxa. Returns may be driven by several mechanisms, including memory, habitat selection, or chance; however, pattern‐based definitions group different generating mechanisms under the same label of ‘site fidelity’, often assuming memory as

True site fidelity in pollen‐feeding butterflies

Functional Ecology, 2021
Abstract Site fidelity plays an important role in increasing foraging efficiency, particularly when food resources are reliable. In insects, site fidelity has largely been studied in Hymenopteran species, which consistently return to their nest site after foraging bouts.

Is mate fidelity related to site fidelity? A comparative analysis in Ciconiiforms

Animal Behaviour, 2000
We tested for an association between divorce rate and site fidelity in 42 avian species belonging to the order Ciconiiforms, using comparative methods that account for the influences of phylogenetic relationships on the data. Our methods enabled us to detect evidence of correlated evolution and provided information on the temporal ordering of ...

Site fidelity as a maladaptive behavior in the Anthropocene

Frontiers in Ecology and the Environment, 2022
Site fidelity, or the behavior of returning to previously visited locations, has been observed across taxa and ecosystems. By developing familiarity with a particular location, site fidelity provides a range of benefits and is advantageous in stable or predictable environments. However, the Anthropocene is characterized by rates of environmental change

Home-site fidelity in migratory honeybees

Nature, 2000
Home-site fidelity is well known in migratory animals, but not in social insects. Here we show that colonies of the giant honeybee Apis dorsata are able to find the same nest location even after seasonal migration. As worker bees do not have first-hand knowledge of the old nest site, the swarms must be guided by some form of genetic mechanism.

Site Fidelity, Mate Fidelity, and Breeding Dispersal in American Kestrels

The Wilson Journal of Ornithology, 2009
Abstract We assessed mate fidelity, nest-box fidelity, and breeding dispersal distances of American Kestrels (Falco sparverius) nesting in boxes in southwestern Idaho from 1990 through 2006. Seventy-seven percent of boxes had different males and 87% had different females where nest-box occupants were identified in consecutive years. High turnover rates

Evidence for memorized site-fidelity in Anopheles arabiensis

Transactions of the Royal Society of Tropical Medicine and Hygiene, 2001
A mark-recapture experiment was carried out in northern Tanzania to determine whether Anopheles arabiensis exhibits memory, by investigating if bloodfed individuals would return to either the location or the host where or on which they had obtained a previous bloodmeal, behaviours termed site-fidelity and host-fidelity respectively.

Control of the structural fidelity of microtubules by initiation sites

Journal of Molecular Biology, 1982
The microtubules in most cells have 13 protofilaments. We show here that microtubules in pig brain also have 13 protofilaments. However, microtubules self-assembled in vitro from pig brain microtubule protein have a distribution of protofilament numbers other than 13.
