Counting the Fingers of Birds and Dinosaurs
Homologies of the three fingers in birds have been debated for more than a century. Paleontologists have traditionally identified avian digits as I-II-III largely on the basis of phalangeal counts, whereas embryologists number them II-III-IV on the basis of development in the egg. The report by Ann C. Burke and Alan Feduccia (1) is a synthesis of the embryological evidence. They observe that in...
متن کاملVisual acuities "hand motion" and "counting fingers" can be quantified with the freiburg visual acuity test.
PURPOSE The visual acuity (VA) of patients with very low vision is classified using the semiquantitative scale "counting fingers" (CF), "hand motion" (HM), "light perception" (LP), and "no light perception." More quantitative measures would be desirable, especially for clinical studies. The results of clinical VA measurements, Early Treatment Diabetic Retinopathy Study (ETDRS) charts, and the F...
متن کاملFingers as a Tool for Counting – Naturally Fixed or Culturally Flexible?
IntroductIon Like number words and written numerals, fingers can be used to represent numbers. In fact, due to their ubiquitous availability, agility, and discrete quantity, they are considered the most natural tool for counting, which renders them attractive for theories of embodied (numerical) cognition (Andres et al., 2008; Di Luca and Pesenti, 2011). As they are so closely linked to the hum...
متن کاملCounting with the Crowd
In this paper, we address the problem of selectivity estimation in a crowdsourced database. Specifically, we develop several techniques for using workers on a crowdsourcing platform like Amazon’s Mechanical Turk to estimate the fraction of items in a dataset (e.g., a collection of photos) that satisfy some property or predicate (e.g., photos of trees). We do this without explicitly iterating th...
متن کاملOn the Means of the Values of Prime Counting Function
In this paper, we investigate the means of the values of prime counting function $pi(x)$. First, we compute the arithmetic, the geometric, and the harmonic means of the values of this function, and then we study the limit value of the ratio of them.
