We investigate the structure of the two permutation classes defined by the sets of forbidden patterns {1234, 2341} and {1243, 2314}. By considering how the Hasse graphs of permutations in these classes can be built from a sequence of rooted source graphs, we determine their algebraic generating functions. Our approach is similar to that of “adding a slice”, used previously to enumerate various ...

This paper describes the UniRo Universal Plug and Play (UPnP) Audio Video (AV) stack that was implemented in Java programming language. The UniRo UPnP AV Stack is a software component that can be used to develop AV applications (MediaServer, MediaRenderer, and AV Control Points). The AV interfaces form the core of this component. They provide a typing layer to access AV devices and AV services....

It is hard to find a class of natural language phenomena which exhibits more complex interactions between syntax and semantics than comparative constructions. Comparatives come with phrasal or clausal complements. In this paper, we focus on phrasal comparatives, which on first inspection look simpler than the clausal ones, but in fact add a degree of complexity. We will consider predicative com...

OBJECTIVES The goal of this study was to determine how often atrioventricular (AV) block is really caused by medications. BACKGROUND Beta-blockers, verapamil, and diltiazem are considered a cause of AV block for which pacemaker implantation is not indicated. However, it is not known if such patients can expect a benign course after discontinuation of the culprit medication. METHODS Consecut...

In order to determine the suitability of vaccine strains established in the 1960s for a new vaccine, a comprehensive study of strain variation of adenovirus serotype 4 (AV 4) and AV 7 was undertaken. A 1,500-bp region of the hexon gene containing the AV neutralization epitopes from prototype, vaccine, and community-acquired strains and from wild-type strains from military personnel that cause a...

This audiovisual program consists of 52 slides, a 51-minute tape, and an accompanying booklet. It is designed as a self-instructional experience in which the viewer becomes an active participant by following the booklet as well as the slide tape sequence. Slides 1 to 22 deal effectively with basic radiation physics. Colorful slides and clear basic explanations introduce the viewer to such topic...

Introduction Determining the level of atrioventricular [AV] block noninvasively can be challenging (ie, AV nodal versus His-Purkinje system). Presyncope or syncope in the setting of AV block is often assumed to be due to progression of the conduction disease. We describe a woman with second-degree AV block with narrow complex QRS with unclear level of AV block. She developed pause-dependent tor...

The objective of this study was to evaluate the effects of level of concentrate acidogenic value (AV) and forage particle size on ruminal pH and feed intake in lactating dairy cows. Two isoenergetic (net energy for lactation = 1.5 +/- 0.01 Mcal/kg) and isonitrogenous (crude protein = 17.4 +/- 0.1% dry matter) concentrates with either a low AV or high AV were formulated and fed in a total mixed ...

In seven patients with symptomatic atrial fibrillation and uncontrollable ventricular rates, selective catheterization of the atrioventricular (AV) nodal artery was performed to chemically destroy the AV node. Ethanol at a concentration of 96% and a dose of 0.5-2 ml was used after selective catheterization of the AV nodal artery had demonstrated temporary AV block after the administration of is...
