potential from AdS-CFT relation at : Dependence on orientation in internal space and higher curvature corrections
Within the classical approximation we calculate the static
potential via the AdS/CFT relation for nonzero temperature and arbitrary
internal orientation of the quarks. We use a higher order curvature corrected
target space background. For timelike Wilson loops there arises a critical line
in the orientation-distance plane which is shifted to larger distances relative
to the calculation with uncorrected background. Beyond that line there is no
-force. The overall vanishing of the force for antipodal orientation
known from zero tempera ture remains valid. The spacelike Wilson loops yield a
string tension for a (2+1)-dimensional gauge theory, independent of the
relative internal orientation, but sensitive to the background correction.Comment: Used background has been adapted to hep-th/9808126 and revised
version of hep-th/9805156, slightly changed comment on 1/L ter
Accounting Ethics Education: An Authentic Value-Based Approach
In order to infuse the teaching of ethics in the field of Accounting as well as within a business school curriculum per se, the traditional neo-classical method must move away from the microcosm of self in favor of consideration for others
Personnel emergency carrier vehicle
A personnel emergency carrier vehicle is disclosed which includes a vehicle frame supported on steerable front wheels and driven rear wheels. A supply of breathing air is connected to quick connect face mask coupling and umbilical cord couplings for supplying breathing air to an injured worker or attendant either with or without a self-contained atmospheric protection suit for protection against hazardous gases at an accident site. A non-sparking hydraulic motion is utilized to drive the vehicle and suitable direction and throttling controls are provided for controlling the delivery of a hydraulic driving fluid from a pressurized hydraulic fluid accumulator. A steering axis is steerable through a handle to steer the front wheels through a linkage assembly
Radio Observations of 4079 Quasars
Using the NVSS radio catalog, we have searched for radio emission from 4079
quasars taken from the 1996 version of the Veron-Cetty and Veron (1996) quasar
catalog. The comparison resulted in the positive detection of radio emission
from 799 quasars. Of these, 168 are new radio detections. Examination of the
radio luminosities shows a dramatic increase in the fraction of radio-loud
quasars from the current epoch to z=0.5 and a gradual decline beyond z=1.0.
Inspection of the radio-loud fraction as a function of M_B shows little
dependence fainter than M_B=-29.5.Comment: 25 pages, including 9 figures and 1 tabl
PACKER: a switchbox router based on conflict elimination by local transformations
PACKER is an algorithm for switchbox routing, based on a novel approach. In an initial phase, the connectivity of each net is established without taking the other nets into account. In general, this gives rise to conflicts (short circuits). In the second stage, the conflicts are removed iteratively using connectivity-preserving local transformations. They reshape a net by displacing one of its segments without disconnecting it from the net. The transformations are applied in a asystematic way using a scan line technique. The results obtained by PACKER are very positive: it solves all well-known benchmark example
