Moths of several families, notably the Noctuidae, Arctiidae and Geometridae, have tympanic organs sensitive to pulsed ultrasound (Eggers, 1919; Haskell & Belton, 1956; Roeder & Treat, 1957). It has long been suspected that moths could hear the cries of approaching bats which prey upon them (White, 1877) and a variety of behavioural responses to natural and artificial acoustic stimuli have been ...
In this Supplement, we provide four sections intended to amplify and/or expand on specific topics raised in the main text. The first section is an assessment of the data underlying Roeder and Emslie (1970) as given in an unpublished table made available by the senior author. We assess general quality and consider possible sources for the discrepancy in values between the canonical 0.30 obtained...
In the present paper we study Geodesic Deviation Equation (GDE) in modified $f(Q)$-gravity theories. The formulation of GDE General Relativity case homogeneous and isotropic Friedman-Lema\^{i}tre-Robertson-Walker (FLRW) spacetime is briefly discussed then extended using its covariant counterpart. generalised Mattig relation obtained. Finally, an equivalent expression to Dyer-Roeder equation pre...
for example, did eukaryotic cells have three RNA poly-merases and what were the specific functions of each of these enzymes? Clues to some of these mysteries came later in Bob's graduate work, when he found that At 9AM on a Saturday morning in the Fall of 1985, we made our way to the 15 th floor of Rockefeller University's RNA polymerase I was localized to the nucleolus, while polymerases II an...
Several authors have reported the presence of ascending giant fibres (AGF) in the nerve cord of the American cockroach, Periplaneta americana (Pumphrey & Rawdon-Smith, 1937; Roeder, 1948; Hess, 1958). Roeder (1948) presented a scheme showing a synaptic link (in the 6th abdominal ganglion) between the cereal sensory neurones and the AGF, the latter then ascending as continuous fibres to the meta...
We have obtained analytical exact solutions of the Dyer-Roeder equation in a cosmological model where creation of particles occurs at the expenses of the gravitational field. We discussed the influences of in-homogeneities in the path of a light beam on the apparent diameter of astrophysical objects and consider both redshift independent as redshift dependent distributions of the inhomogeneities.
