On Ignition of Coalgas-Air Mixtures by Corona Discharges, and Current-Potential Characteristics of a Corona Discharge
1. Ignition of inflammable gaseous mixtures by sparks and by break arcs has been investigated by many workers and a theory developed, but only passing and contradictory references have been made to ignition by corona discharges. 2. It was not found possible to perform, satisfactorily, experiments which depended on the charging of an insulating surface, to a given surface density, by contact with a charged metal surface. 3. Only negative results were obtained, when attempts were made to ignite coalgas-air mixtures by the discharge of electricity between the surfaces of good insulators, such as paraffin wax, ebonite, or cold glass. 4. It is possible to ignite inflammable coalgas-air mixtures by the discharge of electricity between the surfaces of less good insulators, such as white fibre, glass at 10

The Primary Pretenders
We call a composite number q such that there exists a positive integer b with
b^p == b (mod q) a prime pretender to base b. The least prime pretender to base
b is the primary pretender q_b. It is shown that there are only 132 distinct
primary pretenders, and that q_b is a periodic function of b whose period is
the 122-digit number

Quantum Error Correction and Orthogonal Geometry
A group theoretic framework is introduced that simplifies the description of
known quantum error-correcting codes and greatly facilitates the construction
of new examples. Codes are given which map 3 qubits to 8 qubits correcting 1
error, 4 to 10 qubits correcting 1 error, 1 to 13 qubits correcting 2 errors,
and 1 to 29 qubits correcting 5 errors.Comment: RevTex, 4 pages, no figures, submitted to Phys. Rev. Letters. We have
changed the statement of Theorem 2 to correct it -- we now get worse rates
than we previously claimed for our quantum codes. Minor changes have been
made to the rest of the pape
Quantum Error Correction via Codes over GF(4)
The problem of finding quantum error-correcting codes is transformed into the
problem of finding additive codes over the field GF(4) which are
self-orthogonal with respect to a certain trace inner product. Many new codes
and new bounds are presented, as well as a table of upper and lower bounds on
such codes of length up to 30 qubits.Comment: Latex, 46 pages. To appear in IEEE Transactions on Information
Theory. Replaced Sept. 24, 1996, to correct a number of minor errors.
Replaced Sept. 10, 1997. The second section has been completely rewritten,
and should hopefully be much clearer. We have also added a new section
discussing the developments of the past year. Finally, we again corrected a
number of minor error
The Incident at Cavalese and Strategic Compensation
In 1953 the United States ratified the North Atlantic Treaty Organization\u27s Status of Forces Agreement of 1951 (SOFA), which set forth conditions and terms which will control the status of forces sent by one state, party to the Agreement, into the territory of another state, party to the Agreement. The drafters foresaw that the presence and training of foreign military forces within and between their territories would probably, if not inevitably, cause injury to civilians, giving rise to claims that, if not settled quickly and satisfactorily, could spark incidents disruptive to their cooperation in mutual defense. To this end, the SOFA established a jurisdictional regime designed to minimize the political friction these incidents threatened to generate, by providing prompt and manifestly fair settlement procedures. The SOFA\u27s jurisdictional framework protects nationals of a foreign military force from the criminal processes of the alien jurisdiction in which they reside and train, yet permits injured citizens of the host state to pursue civil damages for the tortious acts of foreign forces without fear that their claims might receive prejudicial treatment in the foreign state\u27s local courts
Indirect Expropriation and its Valuation in the BIT Generation
The number of bilateral investment treaties (BITs) has increased dramatically in the past decade. Until the mid-1970s, a bare handful of BITs existed, and the numbers increased only at a slow or moderate pace until the early 1990s. By September 1994, however, some 140 states had concluded more than 700 BITs, by 1999, more than 1300 BITs had entered into force among about 160 stats, and by the end of 2002, 2181 BITs had been signed. Particular provisions of BITs vary from state to state. But certain general features, which respond to the demands of expanding globalization and, as a consequence, the increasing interdependence of national economies, characterize virtually all BITs. BITs seek to establish a stable, orderly framework for investment by creating, as the preamble to a typical United Kingdom BIT states, \u27favourable conditions for greater investment by nationals and companies of one state in the territory of the other state.\u2
