Establishment of swimming posture teaching model based on integrated algorithm / Estabelecimento do modelo de ensino de postura na natação baseado no algoritmo integrado / Establecimiento de un modelo de enseñanza de la postura de natación basado en algoritmos integrados

ABSTRACT As people's lives become better and better, more and more citizens are no longer satisfied with simple food-and-clothing problems, but gradually move towards the spiritual life they are yearning for. Among this, physical health is also an important part of it. So, at this stage, a lot of people will go swimming to exercise their body and mind. In this paper, the integration algorithm was used, and the self-learning ability of the integration algorithm was used. This algorithm was used to study the swimming posture model. This model can play an important role in the teaching of traditional swimming posture.

RESUMO À medida que a vida das pessoas se torna melhor, cada vez mais cidadãos já não se contentam com problemas simples como comida e vestuário, mas, gradualmente, passam a cuidar da vida espiritual que anseiam. Nesse contexto, a saúde física é também um fator importante. Então, nesse estágio, muita gente passa a fazer natação para exercitar o corpo e a mente. Neste artigo, utilizou-se o algoritmo de integração, além da capacidade de autoaprendizagem do algoritmo. Utilizou-se o algoritmo para estudar o modelo de postura na natação, que pode desempenhar um papel importante no ensino da tradicional postura de natação.

Why abundant tropical tree species are phylogenetically old.

Neutral models of species diversity predict patterns of abundance for communities in which all individuals are ecologically equivalent. These models were originally developed for Panamanian trees and successfully reproduce observed distributions of abundance. Neutral models also make macroevolutionary predictions that have rarely been evaluated or tested. Here we show that neutral models predict a humped or flat relationship between species age and population size. In contrast, ages and abundances of tree species in the Panamanian Canal watershed are found to be positively correlated, which falsifies the models. Speciation rates vary among phylogenetic lineages and are partially heritable from mother to daughter species. Variable speciation rates in an otherwise neutral model lead to a demographic advantage for species with low speciation rate. This demographic advantage results in a positive correlation between species age and abundance, as found in the Panamanian tropical forest community.
