Minutes of the CD-ROM Workshop
The workshop described in this document had two goals: (1) to establish guidelines for the CD-ROM as a tool to distribute datasets; and (2) to evaluate current scientific CD-ROM projects as an archive. Workshop attendees were urged to coordinate with European groups to develop CD-ROM, which is already available at low cost in the U.S., as a distribution medium for astronomical datasets. It was noted that NASA has made the CD Publisher at the National Space Science Data Center (NSSDC) available to the scientific community when the Publisher is not needed for NASA work. NSSDC's goal is to provide the Publisher's user with the hardware and software tools needed to design a user's dataset for distribution. This includes producing a master CD and copies. The prerequisite premastering process is described, as well as guidelines for CD-ROM construction. The production of discs was evaluated. CD-ROM projects, guidelines, and problems of the technology were discussed
Controlling the crystal polymorph by exploiting the time dependence of nucleation rates
Most substances can crystallise into two or more different crystal lattices,
called polymorphs. Despite this, there are no systems in which we can
quantitatively predict the probability of one competing polymorph forming,
instead of the other. We address this problem using large scale (hundreds of
events) studies of the competing nucleation of the alpha and gamma polymorphs
of glycine. In situ Raman spectroscopy is used to identify the polymorph of
each crystal. We find that the nucleation kinetics of the two polymorphs is
very different. Nucleation of the alpha polymorph starts off slowly but
accelerates, while nucleation of the gamma polymorph starts off fast but then
slows. We exploit this difference to increase the purity with which we obtain
the gamma polymorph by a factor of ten. The statistics of the nucleation of
crystals is analogous to that of human mortality, and using a result from
medical statistics we show that conventional nucleation data can say nothing
about what, if any, are the correlations between competing nucleation
processes. Thus we can show that, with data of our form, it is impossible to
disentangle the competing nucleation processes. We also find that the growth
rate and the shape of a crystal depends on when it nucleated. This is new
evidence that nucleation and growth are linked.Comment: 8 pages, plus 17 pages of supplementary materia
Right Problem; Wrong Solution
In Boumediene v. Bush, the Supreme Court, in a powerful and eloquent majority opinion by Justice Anthony Kennedy, vindicated the right of a non-U.S. citizen, held in custody at a military base outside the United States, to use the writ to challenge the legality of his incarceration.1 Boumediene was a triumph of both the individual petitioner and the judiciary over the powers of the executive, and represents a high-water mark in the long and celebrated history of habeas
Rethinking the Federal Role in State Criminal Justice
This Essay argues that federal habeas review of state criminal cases squanders resources the federal government should be using to help states reform their systems of defense representation. A 2007 empirical study reveals that federal habeas review is inaccessible to most state prisoners convicted of non-capital crimes, and offers no realistic hope of relief for those who reach federal court. As a means of correcting or deterring constitutional error in non-capital cases, habeas is failing and cannot be fixed. Drawing upon these findings as well as the Supreme Court\u27s most recent decision applying the Suspension Clause, the authors propose that Congress eliminate federal habeas review of state criminal judgments, except for cases including certain claims of actual innocence, retroactively applicable rules, or the sentence of death. The federal government should leave the review of all other state criminal judgments to the state courts and invest, instead, in a new federal initiative to encourage improved state defense services, an approach that can deter and correct constitutional error more effectively than any amount of habeas litigation ever could
