speed and provided both additional and novel augmentation methods, added real-time, and multi-animal support. In v3.0+ we have changed the backend to support PyTorch. This brings not only an easier installation process for users, but performance gains, developer flexibility, and a lot of new ...
The role of pedagogical love in second language (L2) education has long remained under-explored due to dogmatic religious and cultural beliefs. There is in
theoretical models of bird color vision must consider that birds have tetrachromatic vision; birds possess four retinal color cone types, which allow birds to see ultraviolet/violet (uv/v) wavelengths in addition
Biologists have reported on the chemical defences and the phenetic similarity of net-winged beetles (Coleoptera: Lycidae) and their co-mimics. Nevertheless, our knowledge has remained fragmental, and the evolution of mimetic patterns has not been studied
2.2. Sampling design A random stratified sampling was performed to select the sites to characterize pollutants accumulation and lichen diversity inside the green space. Stratification was done by vegetation type, taking into account its structure complexity (6 different types of vegetation): original woo...
Types with higher-than-average fitness will proliferate; types with lower-than-average fitness will decline [53]. In contrast to Eq. (3), the general form of the replicator equation has a frequency-dependent fitness function that is the fitness \({\partial W(x,p(x,t),t)}/{\partial t...
We sampled beetles once in each of the 24 sites, with a total of two to four sites being sampled in a given day. Beetles were captured using pitfall traps: one trap for each of the 8 sampling points in the 4-ha plots. Traps consisted of cylindrical plastic containers (19 cm diameter ...
Q3: Why does the contact level algorithm ignore some influence factors, for example, types of viruses? A3: There are many influence factors, such as types of viruses, temperature, people’s health condition, etc. Considering too many factors will lead to extreme complexity and put forward highe...
It is well known that road-kill data include potential sampling biases as simple counts of dead individuals do not provide valid information about the probability of hedgehogs being killed in traffic. Risk calculations require both the numerator (number killed) and denominator (number exposed to ...
We define matrices and how to add and multiply them, and introduce some special types of matrices.★★★ (440 ratings) Introduction to Dynamical Systems and Chaos Santa Fe Institute via Complexity Explorer In this course you’ll gain an introduction to the modern study of dynamical systems, the...
