The Verkhovna Rada Should Establish Courts of Limited Jurisdiction with Both Civil and Criminal Jurisdiction as Part of Ukrainian Judicial Reform
This article offers suggestions to the Ukraine Parliament on how to create an effective small claims court that addresses misdemeanor criminal cases, preliminary hearings and limited damages civil jurisdiction. The paper is one of nine papers presented by American judges offering prototype blueprints for the three basic levels of courts in Ukraine. Three judges addressed appeals, three judges addressed general jurisdiction courts, and this paper was one of the three papers addressing limited jurisdiction courts. The papers were written at the request of the National Judicial College and USAid.gov to guide Ukraineâs efforts to strengthen their judiciary. The author is a Tennessee municipal judge and a Native American appellate jurist
Black p-Branes versus black holes in non-asymptotically flat Einstein-Yang-Mills theory
We present a class of non-asymptotically flat (NAF) charged black p-branes
(BpB) with p-compact dimensions in higher dimensional Einstein-Yang-Mills
theory. Asymptotically the NAF structure manifests itself as an anti-de-sitter
spacetime. We determine the total mass / energy enclosed in a thin-shell
located outside the event horizon. By comparing the entropies of BpB with those
of black holes in same dimensions we derive transition criteria between the two
types of black objects. Given certain conditions satisfied our analysis shows
that BpB can be considered excited states of black holes. An event horizon
versus charge square plot \ for the BpB reveals such a
transition where is related to the horizon radius of the black
hole (BH) both with the common charge Comment: 10 pages, 1 figure, updated version. Final version to be published in

The Collapse of Large Extra Dimensions
In models of spacetime that are the product of a four-dimensional spacetime
with an ``extra'' dimension, there is the possibility that the extra dimension
will collapse to zero size, forming a singularity. We ask whether this collapse
is likely to destroy the spacetime. We argue, by an appeal to the
four-dimensional cosmic censorship conjecture, that--at least in the case when
the extra dimension is homogeneous--such a collapse will lead to a singularity
hidden within a black string. We also construct explicit initial data for a
spacetime in which such a collapse is guaranteed to occur and show how the
formation of a naked singularity is likely avoided.Comment: Uses revtex
Risk modelling of fires and explosions in open-sided offshore platform modules
Incidents involving fires and explosions present a major hazard to the workforce on
offshore oil and gas platforms. Following the Piper Alpha Disaster in 1988, platform
operators for the UK sector are required to submit safety cases for approval by the
Health and Safety Executive. A key requirement of these safety cases is that hazards
associated with an accidental release of hydrocarbons have been demonstrated to be
as low as reasonably practicable.
This paper aims to describe a process for estimating the expected number of fatalities
on offshore platforms with open-sided modules using a Monte Carlo simulation
method implemented within the SAROS (Safety and Reliability of Offshore
Structures) software. The process involves estimation of the frequency and magnitude
of jet fires, pool fires and explosions. This is combined with the distribution of the
workforce over the platform at the time of the incident to predict the risk of fatality
Non-abelian magnetic black strings versus black holes
We present dimensional pure magnetic Yang-Mills (YM) black strings (or
branes) induced by the dimensional Einstein-Yang-Mills-Dilaton black
holes. Born-Infeld version of the YM field makes our starting point which goes
to the standard YM field through a limiting procedure. The lifting from black
holes to black strings, (with less number of fields) is by adding an extra,
compact coordinate. This amounts to the change of horizon topology from
to a product structure. Our black string in dimensions is a
rather special one, with uniform Hawking temperature and non-asymptotically
flat structure. As the YM charge becomes large the string gets thinner to tend
into a breaking point and transform into a % dimensional black hole.Comment: 5 pages no figure; Final version to appear in EPJ

Open String Star as a Continuous Moyal Product
We establish that the open string star product in the zero momentum sector
can be described as a continuous tensor product of mutually commuting two
dimensional Moyal star products. Let the continuous variable parametrize the eigenvalues of the Neumann matrices; then the
noncommutativity parameter is given by .
For each , the Moyal coordinates are a linear combination of even
position modes, and the Fourier transform of a linear combination of odd
position modes. The commuting coordinate at is identified as the
momentum carried by half the string. We discuss the relation to Bars' work, and
attempt to write the string field action as a noncommutative field theory.Comment: 30 pages, LaTeX. One reference adde
Nucleotide Frequencies in Human Genome and Fibonacci Numbers
This work presents a mathematical model that establishes an interesting
connection between nucleotide frequencies in human single-stranded DNA and the
famous Fibonacci's numbers. The model relies on two assumptions. First,
Chargaff's second parity rule should be valid, and, second, the nucleotide
frequencies should approach limit values when the number of bases is
sufficiently large. Under these two hypotheses, it is possible to predict the
human nucleotide frequencies with accuracy. It is noteworthy, that the
predicted values are solutions of an optimization problem, which is commonplace
in many nature's phenomena.Comment: 12 pages, 2 figure
