We used three years of house finch, Haemorhous mexicanus, song recordings spanning four decades in the introduced eastern range to assess how individual level cultural transmission mechanisms drive population changes birdsong. First, we developed an agent-based model (available as a new R package called ‘TransmissionBias’) that simulates finch given different parameters related biases, or biase...

Image enhancement techniques (such as edge and contrast enhancement) are essential for many imaging applications. In incoherent holography such Fresnel correlation (FINCH), the light from an object is split into two, each of which modulated differently one another by two different quadratic phase functions coherently interfered to generate hologram. The hologram can be reconstructed via a numer...

To the Editor: which in the absence of anemia increases th rate of red blood cell In a recent excellent review on iron balance in humans,' Dr ClemProduction.'" ent Finch briefly discussed compensated hemolytic anemia in pa. Dr Finch states in his review without a specific reference that the tients with hereditary spherocytosis. For years I have been interested erythropoietin titer in this c...

The starting point of this article is represented by a recent work of Finch [2000]. Based on two asymptotic results concerning the Erdos function, he proposed some interesting equation concerning the moments of the Smarandache function. The aim of this note is give a bit modified proof and to show some computation results for one of the Finch equation. We will call the numbers obtained from com...

A Sierpiński number is an odd integer k with the property that k ·2+1 is composite for all positive integer values of n. A Riesel number is defined similarly; the only difference is that k · 2 − 1 is composite for all positive integer values of n. In this paper we find Sierpiński and Riesel numbers among the terms of the wellknown Fibonacci sequence. These numbers are smaller than all previousl...

When Hitler (1927/1999) reflected on his political struggle, he explored three topics regarding race mixture1: Race mixture was against nature, it meant the end of culture, and it lowered the level of the higher race. Hitler’s technique of problematization—his way of showing why race mixture was against nature—was crude. He used the term “species” when talking about races, a common practice in ...

Janet Finch's chapter explores some of the ethical problems involved in interviewing women. Drawing on her own work in which she interviewed clergy wives, and mothers involved in playgroups, she looks at the development of trust in the interview situation, and the exploitative potential of this. As she points out, if you are a woman sociologist, reasonably skilled m the arts of qualitative rese...

Recent advances in Fresnel incoherent correlation holography (FINCH) increase the signal-to-noise ratio in hologram recording by interference of images from two diffractive lenses with focal lengths close to the image plane. Holograms requiring short reconstruction distances are created that reconstruct poorly with existing Fresnel propagation methods. Here we show a dramatic improvement in rec...

Abstract Nesting success tends to increase with age in birds, part because older birds select more concealed nest sites based on experience and/or an assessment of prevailing predation risk. In general, greater plant diversity is associated biodiversity and vegetation cover. Here, we ask if Darwin’s finch males areas cover these also have avian species assessed using song. We compared patterns ...
