A theoretical framework for TTO valuations and a taxonomy of TTO approaches: results from a pilot study
Coherence, engagement, and usefulness as sensemaking criteria in participatory media practice
When skilled practitioners create media artifacts such as web pages, newspaper articles, videos, or business presentations, they are engaging in a pursuit which has consequences for the people who will interact with those artifacts. The juncture of practice, artifact, and consequences involves diverse normative considerations. We have summarized these into three criteria: coherence, engagement, and usefulness. In this paper we report on initial progress to develop a method for assessing these criteria in a particular form of skilled real-time media practice
Digging Deeper: James Connolly in America
This project continued research into James Connolly\u27s time in America from 1902-1910. It focused on primary sources in the hopes to unearth things not found in the secondary writing on Connolly’s activities during this influential time. The O’Brien papers are an eclectic collection of primary documents from Connolly’s life, including letters between James Connolly and his friend John Matheson, correspondence with other socialists, and some of Connolly’s own writing. The New York Call was a daily socialist newspaper that contains ads for Connolly’s lectures and his magazine, The Harp, as well as meetings of his organization, the Irish Socialist Federation. Through these primary sources and others, more of James Connolly’s activities and perspectives during his time in America come to light
Noise Limited Computational Speed
In modern transistor based logic gates, the impact of noise on computation
has become increasingly relevant since the voltage scaling strategy, aimed at
decreasing the dissipated power, has increased the probability of error due to
the reduced switching threshold voltages. In this paper we discuss the role of
noise in a two state model that mimic the dynamics of standard logic gates and
show that the presence of the noise sets a fundamental limit to the computing
speed. An optimal idle time interval that minimizes the error probability, is
derived
On the structure of framed vertex operator algebras and their pointwise frame stabilizers
In this paper, we study the structure of a general framed vertex operator
algebra. We show that the structure codes (C,D) of a framed VOA V satisfy
certain duality conditions. As a consequence, we prove that every framed VOA is
a simple current extension of the associated binary code VOA V_C. This result
would give a prospect on the classification of framed vertex operator algebras.
In addition, the pointwise frame stabilizer of V is studied. We completely
determine all automorphisms in this pointwise stabilizer, which are of order 1,
2 or 4. The 4A-twisted sector and the 4A-twisted orbifold theory of the famous
Moonshine VOA are also constructed explicitly. We verify that the top module of
this twisted sector is of dimension 1 and of weight 3/4 and the VOA obtained by
4A-twisted orbifold construction of the moonshine VOA is isomorphic to the
moonshine VOA itself.Comment: Version 3: 59 pages. Corrected version. 54 pages on my LaTeX system
version 2: We add Theorem 5.16 in which we give a necessary and sufficient
condtion for a code to be a structure code of a holomorphic framed VOA.

Quantum Fluctuations of a Coulomb Potential as a Source of Flicker Noise
The power spectrum of quantum fluctuations of the electromagnetic field
produced by an elementary particle is determined. It is found that in a wide
range of practically important frequencies the power spectrum of fluctuations
exhibits an inverse frequency dependence. The magnitude of fluctuations
produced by a conducting sample is shown to have a Gaussian distribution around
its mean value, and its dependence on the sample geometry is determined. In
particular, it is demonstrated that for geometrically similar samples the power
spectrum is inversely proportional to the sample volume. It is argued also that
the magnitude of fluctuations induced by external electric field is
proportional to the field strength squared. A comparison with experimental data
on flicker noise measurements in continuous metal films is made.Comment: 11 pages, substantially corrected and extende
Actions of Agonists, Fipronil and Ivermectin on the Predominant In Vivo Splice and Edit Variant (RDLbd, I/V) of the Drosophila GABA Receptor Expressed in Xenopus laevis Oocytes
Ionotropic GABA receptors are the targets for several classes of insecticides. One of the most widely-studied insect GABA receptors is RDL (resistance to dieldrin), originally isolated from Drosophila melanogaster. RDL undergoes alternative splicing and RNA editing, which influence the potency of GABA. Most work has focussed on minority isoforms. Here, we report the first characterisation of the predominant native splice variant and RNA edit, combining functional characterisation with molecular modelling of the agonist-binding region. The relative order of agonist potency is GABA> muscimol> TACA> β-alanine. The I/V edit does not alter the potency of GABA compared to RDLbd. Docking calculations suggest that these agonists bind and activate RDLbdI/V through a similar binding mode. TACA and β-alanine are predicted to bind with lower affinity than GABA, potentially explaining their lower potency, whereas the lower potency of muscimol and isoguvacine cannot be explained structurally from the docking calculations. The A301S (resistance to dieldrin) mutation reduced the potency of antagonists picrotoxin, fipronil and pyrafluprole but the I/V edit had no measurable effect. Ivermectin suppressed responses to GABA of RDLbdI/V, RDLbd and RDLbdI/VA301S. The dieldrin resistant variant also showed reduced sensitivity to Ivermectin. This study of a highly abundant insect GABA receptor isoform will help the design of new insecticides

Influence of damping on the vanishing of the electro-optic effect in chiral isotropic media
Using first principles, it is demonstrated that radiative damping alone
cannot lead to a nonvanishing electro-optic effect in a chiral isotropic
medium. This conclusion is in contrast with that obtained by a calculation in
which damping effects are included using the standard phenomenological model.
We show that these predictions differ because the phenomenological damping
equations are valid only in regions where the frequencies of the applied
electromagnetic fields are nearly resonant with the atomic transitions. We also
show that collisional damping can lead to a nonvanishing electrooptic effect,
but with a strength sufficiently weak that it is unlikely to be observable
under realistic laboratory conditions
