Mating plugs in animals are ubiquitous and are commonly interpreted to be products of mating strategies. In spiders, however, mating plugs may also take on functions beyond female remating prevention. Due to the vagaries of female genital (spermathecal) anatomy, most spiders face the problem of havi ...

Introduction: It is generally thought that mating plugs, where present, impede or reduce the possibilities of female subsequent mating. Behavioral studies on numerous spiders, where mating plugs are common, have generally supported this function. However, mating plugs in spiders could plausibly serv ...

spiders;comparative anatomy;genital anatomy;
Our understanding of spider reproductive biology is hampered by the vast anatomical diversity and difficulties associated with its study. Although authors agree on the two general types of female spider genitalia, haplogyne (plesiomorphic) and entelegyne (apomorphic), our understanding of variation ...

It is difficult to judge the failure of clay seepage under a high water pressure.This paper presents a new method to assess clay failure based on the anti-permeability strength, which is the critical water pressure to destroy the clay. An experiment is designed to test the value that avoids the prob ...

In this paper we introduce the notion of Population-based Adaptive Systems (PAS)with 3-tier adaptation by evolutionary, individual, and social learning (EL, IL, SL).We discuss some important aspects of using combinations of these adaptivemechanisms in general. We pay special attention to using natur ...

We compare two recently proposed approaches for representing probability
distributions over the space of permutations in the context of multi-target
tracking. We show that these two representations, the Fourier approximation and
the information form approximation can both be viewed as low dimensiona ...

The three most common approaches for deriving or predicting instantiated relations, i.e. triple statements (s, p, o), are information extraction, reasoning and relational machine learning. Information extraction uses sensory information, typically in form of text, and extracts statements using vario ...

Bayesian network classifiers have been widely used for classification problems. Given a fixed Bayesian network structure, parameter learning can take two different approaches: generative and discriminative learning. While generative parameter learning is more efficient, discriminative parameter lear ...

Precise click prediction is one of the key components in the sponsored search system. Previous studies usually took advantage of two major kinds of information for click prediction, i.e., relevance information representing the similarity between ads and queries and historical click-through informati ...
