In this article, we propose a new surgical device for circumferentially excision of high anal fistulas in a minimally invasive manner. The new apparatus works on the basis of axially rotating and moving a tubular blade along a fistulous tract straightened using a rigid straight guidewire. As the blade moves along the tract, its sharp circular cutting edge circumferentially separates approximate...

Let $X$ be a sufficiently nice scheme. We survey some recent progress on dualizing complexes. It turns out that a complex in $kinj X$ is dualizing if and only if tensor product with it induces an equivalence of categories from Murfet's new category $kmpr X$ to the category $kinj X$. In these terms, it becomes interesting to wonder how to glue such equivalences.

UNLABELLED Optimizing amino acid conformation and identity is a central problem in computational protein design. Protein design algorithms must allow realistic protein flexibility to occur during this optimization, or they may fail to find the best sequence with the lowest energy. Most design algorithms implement side-chain flexibility by allowing the side chains to move between a small set of ...

We report on time-resolved fluorescence anisotropy studies of poly(9-vinylcarbazole) (PVK) nanoparticles (NPs) encapsulating Coumarin 153 (C153) and Nile Red (NR). The wobbling-in-a-cone model successfully describes the restricted movements of the encapsulated molecules. For C153-doped PVK NPs, when increasing the C153 content, the diffusional relaxation (τD) times become shorter (τD = 4.6-1.6 ...

making a conservative bridge using a natural tooth pontic with mobile teeth is complicated, time-consuming and sometimes impossible with the current techniques and materials. the aim of this paper is` to describe a new method using special rigid tray technique (srtt) to deal with such difficult clinical cases.

ground differential movements due to faulting have been observed to cause damage to engineered structures and facilities. although surface fault rupture is not a new problem, there are only a few building codes in the world containing some type of provisions for reducing the risks. fault setbacks or avoidance of construction in the proximity to seismically active faults, are usually supposed as...

Abstract The time-varying response of Earth’s and other planets’ rotation to external gravitational torques depends strongly on their internal structure. In particular, the existence mode known as free core nutation in fluid is amplify forced nutations near-diurnal retrograde frequency band (as measured planetary frame reference). Due proximity shape frequency, this sometimes equated with so-ca...
