A Versatile‐Designable Framework for Active and Programmable Shape‐Morphing Soft Matter Systems: From Inverse Design to Closed‐Loop Control

Advanced Science, EarlyView.
A versatile framework integrates addressable electrothermal actuation and strain‐constraint mechanisms to construct programmable shape‐morphing soft matter systems. By combining an analytical inverse design strategy for high‐fidelity 3D surface reconstruction with deep learning‐based closed‐loop control, this approach enables zero‐energy shape locking,

Balancing Exploration and Exploitation Through a Sequential Hybrid of Roach Infestation and Mayfly Algorithms for Constrained Engineering Design Optimization

AI &Innovation, EarlyView.
ABSTRACT Maintaining an effective balance between exploration and exploitation is essential during optimization processes, from mathematical functions to more complex problems such as constrained engineering design optimization, particularly when addressing highly nonlinear issues with numerous local optima and strict feasibility requirements.

Japanese wolves are most closely related to dogs and share DNA with East Eurasian dogs

Nature Communications
Although the domestic dog’s origin is still unclear, this lineage is believed to have been domesticated from an extinct population of gray wolves, which is expected to be more closely related to dogs than to other populations of gray wolves.

Identification of Sarcocystis and Trichinella Species in Muscles of Gray Wolf (Canis lupus) from Lithuania

Veterinary Sciences
Apicomplexan Sarcocystis and Trichinella nematodes are food-borne parasites whose life cycle is carried-out in various wildlife and domestic animals. The gray wolf (Canis lupus) is an apex predator acting as an ecosystem engineer.

Wolves are back: Sociopolitical identity and opinions on management of Canis lupus

Conservation Science and Practice, 2020
Gray wolves (Canis lupus) were eliminated from the state of Oregon in the middle of the 20th century. By the early 21st century, wolves had returned to the northeast corner of the state, dispersing from populations reintroduced in Idaho and Wyoming. On a

Improving individual identification of wolves (Canis lupus) using the fundamental frequency and amplitude of their howls: a new survey method [PDF]

, 2013
Many bioacoustic studies have been able to identify individual mammals from variations in the fundamental frequency (F0) of their vocalizations. Other characteristics of vocalization which encode individuality, such as amplitude, are less frequently used

Interactions between maternal provisioning and natural selection on seed mass fluctuate across heat waves

American Journal of Botany, EarlyView.
Abstract Premise Changing climates are leading to more frequent and severe heat waves, potentially threatening plant populations. Both acclimation to stress and selection for heat‐escape or heat‐resistance phenotypes occur during heat waves. However, plastic responses and selection do not necessarily interact cohesively—even producing trait responses ...

Fascicle measurement methods do result in lengths that are significantly different

The Anatomical Record, EarlyView.
A recent comparison of the most prevalent methods for measuring fascicles, in situ measurement versus chemical digestion, concluded that the measurements are indistinguishable based on data from different conspecific individuals. However, our study of contralateral muscles of the same individuals shows that the methods clearly result in statistically ...

Echinococcus granulosus in Gray Wolves and Ungulates in Idaho and Montana, USA [PDF]

Journal of Wildlife Diseases, 2009
We evaluated the small intestines of 123 gray wolves (Canis lupus) that were collected from Idaho, USA (n=63), and Montana, USA (n=60), between 2006 and 2008 for the tapeworm Echinococcus granulosus. The tapeworm was detected in 39 of 63 wolves (62%) in Idaho, USA, and 38 of 60 wolves (63%) in Montana, USA.

Evaluating Bergmann's and Allen's rules in the long bones of the eastern gray squirrel

The Anatomical Record, EarlyView.
Abstract Ecogeographical rules predict variation in body size and appendage proportions across climatic gradients, yet intraspecific tests using long bones from wild populations remain limited among small mammals. This study tests the hypothesis that eastern gray squirrels (Sciurus carolinensis) conform to Bergmann's rule, that is, body size increases ...
