In lattice cryptography, worst-case to average-case reductions rely on two problems: Ajtai’s SIS and Regev’s LWE, which both refer to a very small class of random lattices related to the group G = Zq . We generalize worst-case to average-case reductions to all integer lattices of sufficiently large determinant, by allowing G to be any (sufficiently large) finite abelian group. In particular, we...

The 1815 Act to Regulate Madhouses in Scotland (55 Geo. III c. 69) made provision for fee paying patients confined in institutions run by private individuals for profit. It is generally acknowledged to mark the beginning of Scottish legislation about the insane. Most historians of Scottish psychiatry refer to the act in a paradoxical manner that is factual yet also framed in broader terms. Shor...

First published December 24, 2003; 10.1152/ajpcell.00394. 2003.—Metabolic acidosis is associated with alteration in fluid and electrolyte reabsorption in a number of nephron segments. However, the eff...

J Appl Physiol 97: 739–747, 2004; 10.1152/japplphysiol.00185.2004.—A striking characteristic of the blood flow adaptation at exercise onset is the immediate and substantial increase in the first few (0–5 s) seconds of exercise. The purpose of this mini-review is to...

The relationship between forensic laboratories and the other institutions of law enforcement varies widely over space and time in the United States. Some jurisdictions have their own local lab within the police or sheriff’s department, others depend on a statewide lab system either independent or under the state police, and others still contract with a private lab to process their forensic evid...

S U M M A R Y Edge effects are distortions at the edge of a domain which are artifacts of the implicit assumptions of a numerical algorithm or of the limited span of data used to solve the problem (Sheriff, 1991, p. 96). During wavenumber domain filtering of potential-field data, (e.g., reduction to the pole, pseudogravity, and directional derivative, etc.), edge effect distortions are usually ...

To be of any value, a predicted model of an antibody combining site should have an accuracy approaching that of antibody structures determined by x-ray crystallography (1.6-2.7 A). A number of modeling protocols have been proposed, which fall into two main categories--those that adopt a knowledge-based approach and those that attempt to construct the hypervariable loop regions of the antibody a...

This plenary talk at the eighth annual Midwest Rural Agricultural Safety and Health Forum, November 2009, described a conference held earlier in the year focusing on the hazards and risks associated with moving agricultural equipment on public roads. The Farm Equipment-Motor Vehicle Crash Prevention Conference (FEMVCPC), March 2009, Des Moines, Iowa, drew 54 participants representing 13 states ...
