Abstract Many animals lower Jiggers their metabolic rate in response to low temperatures and scarcity of food in the winter in phenomena called hibernation or overwintering.Living at high altitude on the Tibetan Plateau where winters are very cold, the frog Nanorana parkeri, survives in one of the most hostile environments on Earth but, to date, re
Aimed at improving the navigation accuracy of the fixed-wing UAVs in GNSS-denied environments, this paper proposes an algorithm of nongravitational acceleration estimation based on airspeed and IMU sensors, which use a differential tracker (TD) model to further supplement the effect of linear acceleration for UAVs under dynamic flight.We further es
Objective: Telephone Handset Lead In clinical practice, thyroid nodules are typically visually evaluated by expert physicians using 2D ultrasound images.Based on their assessment, a fine needle aspiration (FNA) may be recommended.However, visually classifying thyroid nodules from ultrasound images may lead to unnecessary fine needle aspirations for
Time and space are essential niche dimensions along which species tend to coexist.We assessed spatiotemporal resource partitioning between leopards and lions and hypothesized the differential use of spatiotemporal resources by leopards with respect to lions.We used a systematic camera trap survey to collect the data at 50 sites.The data were analyz
This article features the preliminary characterization of thirty different-colored samples.The scrutinized fragments were taken from the 120-year-old main curtain from the National Theater of Costa Rica.Results from scanning electron microscopy (SEM) shed light on the textiles used, evidencing the presence of cotton in the reinforcement fabric and
