Objective: To describe the safety of the modified open technique for accessing the abdominal cavity and creation of pneumoperitoneum in gynecologic laparoscopy. Methods: A descriptive retrospective chart review of 100 patients who underwent gynecologic laparoscopy at the Jordanian Royal Medical Services Hospitals during the period from January 2008 to December 2009 was conducted. We used the mo...

Nest attentiveness (percentage of time spent on the nest) during incubation represents a parent-offspring conflict; incubating birds must balance a trade-off between caring for embryos by staying on the nest versus caring for themselves by getting off the nest to forage. For species in which females are the sole incubator, males can potentially affect this trade-off and increase nest attentiven...

Open boundary conditions. Since the source current, Eq. 1, extends from z = −∞ to +∞ whereas our computational domain is finite, one has to apply suitable boundary conditions (see also [2]). Consider some accelerator component, residing in a vacuum cavity with attached beam pipe of smaller cross section than the cavity. Generally, the transitions from the pipe to the module have to be included ...

The second-quantization of a scalar field in an open cavity is formulated, from first principles, in terms of the quasinormal modes (QNMs), which are the eigensolutions of the evolution equation that decay exponentially in time as energy leaks to the outside. This formulation provides a description involving the cavity degrees of freedom only, with the outside acting as a (thermal or driven) so...

INTRODUCTION Constuction of the obturator prostheses and providing the patient's comfort with them are very difficult. Primary and the most important stage for these prostheses is to perform a proper impression. CASE PRESENTATION A 55-year-old edentulous Turkish female patient with a congenitally maxillary defect was rehabilitated with an open hollow obturator prosthesis. After the preliminar...

The recently solved crystal structure of YidC protein suggests that it mediates membrane protein insertion by means of an intramembrane cavity rather than a transmembrane (TM) pore. This concept of protein translocation prompted us to characterize the native, membrane-integrated state of YidC with respect to the hydropathic nature of its TM region. Here, we show that the cavity-forming region o...

The chaperonin GroEL assists polypeptide folding through sequential steps of binding nonnative protein in the central cavity of an open ring, via hydrophobic surfaces of its apical domains, followed by encapsulation in a hydrophilic cavity. To examine the binding state, we have classified a large data set of GroEL binary complexes with nonnative malate dehydrogenase (MDH), imaged by cryo-electr...

The radiative interaction of solid-state emitters with cavity fields is the basis of semiconductor microcavity lasers and cavity quantum electrodynamics (CQED) systems. Its control in real time would open new avenues for the generation of non-classical light states, the control of entanglement and the modulation of lasers. However, unlike atomic CQED or circuit quantum electrodynamics, the real...

The recently discovered 150-cavity (formed by loop residues 147-152, N2 numbering) adjacent to the enzymatic active site of group 1 influenza A neuraminidase (NA) has introduced a novel target for the design of next-generation NA inhibitors. However, only group 1 NAs, with the exception of the 2009 pandemic H1N1 NA, possess a 150-cavity, and no 150-cavity has been observed in group 2 NAs. The r...

We investigate steady state entanglement in an open quantum system, specifically a single atom in a driven optical cavity with cavity loss and spontaneous emission. The system reaches a steady pure state when driven very weakly. Under these conditions, there is an optimal value for atom-field coupling to maximize entanglement, as larger coupling favors a loss port due to the cavity enhanced spo...
