This paper provides a novel meta-heuristic optimization algorithm. The behaviors of flying squirrels in the nature are the main inspiration of this research. These behaviors include flying from tree to tree and walking on the ground or on a tree branch to find food. They also contact each other with chirp or squeak. This algorithm is named flying squirrel optimizer (FSO). Two main theories of m...

A brain tumor is a portion of uneven cells, need to be detected earlier for treatment. Magnetic Resonance Imaging (MRI) routinely utilized procedure take images. Manual segmentation crucial task and laborious. There an automated system classification surgery medical treatments. This work suggests efficient based on deep learning techniques. Initially, Squirrel search optimized bidirectional Con...

The northern flying squirrel (Glaucomys sabrinus) is the primary prey of northern spotted owls (Strix occidentalis caurina) and California spotted owls (S. o. occidentalis) throughout much of the owls' ranges. Flying squirrel abundance patterns, however, are poorly documented. Using capture-recapture techniques to estimate density, we compared flying squirrel densities among 3 types of fir (Abi...

One of Europe’s rarest small mammals — the flying squirrel — has been given a boost to save it from extinction, sparing the Finnish government from legal action by the European Commission. The Finnish government has changed its law to protect the squirrels and paid out one million euros in compensation to about 400 farmers and landowners who have to curb normal activities for the squirrels’ saf...

The DNA from flying squirrel-associated Rickettsia prowazekii was characterized by using a specific DNA fragment produced by digestion with the enzyme BamHI. The DNA fragment was cloned into a plasmid vector and used to readily distinguish between available human- and flying squirrel-associated R. prowazekii DNAs derived from crude cytoplasmic extracts.

Anecdotal reports of ultrasound use by flying squirrels have existed for decades, yet there has been little detailed analysis of their vocalizations. Here we demonstrate that two species of flying squirrel emit ultrasonic vocalizations. We recorded vocalizations from northern (Glaucomys sabrinus) and southern (G. volans) flying squirrels calling in both the laboratory and at a field site in cen...

We report the presence of Indian Giant Flying Squirrel Petaurista philippensis Elliot, 1839 in Badrama Wildlife Sanctuary, a first record to Odisha. The species was identified through direct sighting and photo capture. also observed feeding behaviour flying squirrels on Tamarind Sal trees sanctuary.
