Can Two Planar Sources With The Same Sets Of Stokes Parameters Generate Beams With Different Degrees Of Polarization?, Mohamed Salem, Olga Korotkova, Emil Wolf

Physics Articles and Papers

It is shown that two stochastic electromagnetic beams that propagate from the source plane z=0 into the half-space z>0 may have different degrees of polarization throughout the half-space, even though they have the same sets of Stokes parameters in the source plane. This fact is due to a possible difference in the coherence properties of the field in that plane, but other reasons are also possible. The result is illustrated by an example.

Invariance And Noninvariance Of The Spectra Of Stochastic Electromagnetic Beams On Propogation, Jixiong Pu, Olga Korotkova, Emil Wolf

Physics Articles and Papers

It has been known for some time that the spectrum of light may change on propagation, even in free space. The theory of this phenomenon was developed within the framework of scalar theory. We generalize it to electromagnetic beams, generated by planar, secondary, stochastic sources. We also derive an electromagnetic analog of the so-called scaling law. When this law is satisfied the normalized spectrum of the beam is the same throughout the far zone and across the source.

Loss Causation In Fraud On The Market Cases Post-Dura Pharmaceuticals, Ann Morales Olazábal

Business Law Articles and Papers

As a critical matter, class action securities fraud plaintiffs employing the fraud-on-the-market theory of reliance must still plead and eventually prove loss causation and damages. The Supreme Court's April 2005 decision in Dura Pharmaceuticals v. Broudo disapproved of the Ninth Circuit's simple price inflation theory of pleading loss causation (namely that a plaintiff's loss occurs at the time she purchases stock at a price artificially inflated by fraud) without expressly sanctioning any of the other prevailing approaches to loss causation. This leaves open the question of precisely how courts should properly handle loss causation. Consequently, this Article critically examines the …

A Dual-Genome Microarray For The Pea Aphid, Acyrthosiphon Pisum, And Its Obligate Bacterial Symbiont, Buchnera Aphidicola, Alex C. C. Wilson, Helen E. Dunbar, Gregory K. Davis, Wayne B. Hunter, David L. Stern, Nancy A. Moran

Biology Articles and Papers

Background

The best studied insect-symbiont system is that of aphids and their primary bacterial endosymbiont Buchnera aphidicola. Buchnera inhabits specialized host cells called bacteriocytes, provides nutrients to the aphid and has co-speciated with its aphid hosts for the past 150 million years. We have used a single microarray to examine gene expression in the pea aphid, Acyrthosiphon pisum, and its resident Buchnera. Very little is known of gene expression in aphids, few studies have examined gene expression in Buchnera, and no study has examined simultaneously the expression profiles of a host and its symbiont. Expression profiling …

In Defense Of The Objective Epistemic Approach To Argumentation, John Biro, Harvey Siegel

Philosophy Articles and Papers

In this paper we defend a particular version of the epistemic approach to argumentation. We advance some general considerations in favor of the approach and then examine the ways in which different versions of it play out with respect to the theory of fallacies, which we see as central to an understanding of argumentation. Epistemic theories divide into objective and subjective versions. We argue in favor of the objective version, showing that it provides a better account than its subjectivist rival of the central fallacy of begging the question. We suggest that the strengths of the objective epistemic theory of …

Magnetic Memory And Current Amplification Devices Using Moving Domain Walls, Stewart E. Barnes, J. Ieda, S. Maekawa

Physics Articles and Papers

A moving magnetic domain wall produces an electromotive force (emf). It is therefore possible to read the state of a magnetic memory device via the emf it produces when subjected to an interrogation pulse. It is also possible to amplify currents in pulse circuits, opening up the possibility of all magnetic logic circuits.

The Genetic Outcomes Of Sex And Recombination In Long-Term Functionally Parthenogenetic Lineages Of Australian Sitobion Aphids, Alex C. C. Wilson, Paul Sunnucks

Biology Articles and Papers

The typical life cycle of an aphid is cyclical parthenogenesis which involves the alternation of sexual and asexual reproduction. However, aphid life cycles, even within a species, can encompass everything on a continuum from obligate sexuality, through facultative sexuality to obligate asexuality. Loss of the sexual cycle in aphids is frequently associated with the introduction of a new pest and can occur for a number of environmental and genetic reasons. Here we investigate loss of sexual function in Sitobion aphids in Australia. Specifically, we aimed to determine whether an absence of sexual reproduction in Australian Sitobion results from genetic loss …
