The University of Maryland Researchers participated in both the Arabic-English Cross Language Information Retrieval (CLIR) and Video tracks of TREC-10. In the CLIR track, our goal was to explore effective monolingual Arabic IR techniques and effective query translation from English to Arabic for cross language IR. For the monolingual part, the use of the… (More)

OBJECTIVE
Arginine vasopressin (AVP) is the primary regulator of free water retention through its interactions with the AVP type 2 receptor (V(2)). As opposed to the natriuresis and diuresis that occur with loop and thiazide diuretics, conivaptan is an AVP V(1A)/V(2) receptor antagonist, which enhances free water excretion while minimizing sodium loss. We… (More)

In this paper we present a novel way of creating mosaics from an MPEG video sequence. Two original aspects of our work are that (1) we explicitly compute camera motion between frames and (2) we deduce the camera motion directly from the motion vectors encoded in the MPEG video stream. This enables us to create mosaics more simply and quickly than with other… (More)

BACKGROUND
The optimal management strategy for neonates with Ebstein's anomaly is unknown. This analysis was undertaken to assess current trends in the management and prognosis of neonates born with Ebstein's anomaly in the United States, as reflected in an administrative database.
METHODS
The Pediatric Health Information System database (40 children's… (More)

The behavior of faulty computer programs is a subject of growing interest. In this paper, we present an empirical study of one aspect of fault behavior: the propagation of data-state errors. A data-state error occurs when a fault is executed and affects a program’s data-state, and it is said to propagate to the output if it affects the outcome of the… (More)

For a strong oriented graph D of order n and diameter d and an integer k with 1 ≤ k ≤ d, the kth power D of D is that digraph having vertex set V (D) with the property that (u, v) is an arc of D if the directed distance ~ dD(u, v) from u to v in D is at most k. For every strong digraph D of order n ≥ 2 and every integer k ≥ ⌈n/2⌉, the digraph D is… (More)

We describe a case of an anomalous right coronary artery from the pulmonary artery that presented in the neonatal period with significant arrhythmias. The repair demonstrates that this can be performed safely and effectively in the neonate.

For a connected graph G of order n ≥ 3, let f : E(G) → Zn be an edge labeling of G. The vertex labeling f ′ : V (G) → Zn induced by f is defined as f (u) = ∑ v∈N(u) f(uv), where the sum is computed in Zn. If f ′ is one-to-one, then f is called a modular edge-graceful labeling and G is a modular edge-graceful graph. A modular edge-graceful labeling f of G is… (More)
