BACKGROUND AND OBJECTIVES The well-known advantages of minimally invasive surgery make the approach well suited for hysterectomy and other gynecological procedures. The removal of specimens excised during surgery has been a challenge that has been answered by the use of power morcellation. With this study we sought to assess the feasibility of power morcellation within a specimen bag. METHODS...

The creation of hypervideos—displayed video streams that contain embedded user-clickable anchors and annotations—is a manual and tedious job, requiring the preparation of assets like still frames, the segmentation of videos in scenes or chapters, and sometimes even the isolation of objects like faces within the video. In this paper, we propose a semi-automated Web-Components-based approach to s...

Cost associated with the maintenance and scale of custom services presents one of the most significant barriers to entry for information providers. One solution proposes pushing computation into the cloud where providers like Amazon maintain a scalable, world-wide platform for virtualization. While this avoids certain hardware maintenance costs, service providers must still maintain clusters of...

We prove that the n-dimensional unit hypercube contains an n-dimensional regular simplex of edge length c √ n, where c > 0 is a constant independent of n. Let l∆n be the n-dimensional regular simplex of edge length l, and let lQn be the n-dimensional hypercube of edge length l. For simplicity, we omit l if l= 1, e.g., Qn denotes the unit hypercube. We are interested in the maximum edge length o...

A disposable, self-contained polymerase chain reaction (PCR) chip with on-board stored, just-on-time releasable, paraffin-passivated, dry reagents is described. During both storage and sample preparation, the paraffin immobilizes and protects the stored reagents. Fluid flow through the reactor leaves the reagents undisturbed. Prior to the amplification step, the chamber is filled with target an...

Using qualitative reasoning with geographic information, contrarily, for instance, with robotics, looks not only fastidious (i.e.: encoding knowledge Propositional Logics PL), but appears to be computational complex, and not tractable at all, most of the time. However, knowledge fusion or revision, is a common operation performed when users merge several different data sets in a unique decision...

We present a rare case of an endometrioma present within and firmly adherent to the broad ligament in a patient who experienced an episode of acute abdominal pain. The endometrioma was excised laparoscopically and the broad ligament repaired.

Tetragonal Na3SbS4 is synthesized as a new sodium superionic conductor. The discovery of Na vacancies experimentally verifies previous theoretical predictions. Na vacancies, distorted cubic sulphur sublattices and large Na atomic displacement parameters lead to the ionic conductivity as high as 3 mS cm-1, a value significantly higher than those of state-of-the-art sodium sulfide electrolytes.

A family J of subsets of {1, . . . , n} is called a j-junta if there exists J ⊆ {1, . . . , n}, with |J | = j, such that the membership of a set S in J depends only on S ∩ J . In this paper we provide a simple description of intersecting families of sets. Let n and k be positive integers with k < n/2, and let A be a family of pairwise intersecting subsets of {1, . . . , n}, all of size k. We sh...

We propose extracting information about characters and actions from a self-contained story, such as news reports. This information is stored in structure patterns called situations. We show how these situation patterns can be constructed by unifying the constituents of sentence analysis with knowledge previously stored in Typed Feature Structures. These situations can be in turn used subsequent...
