partial frames provide a rich context in which to do pointfree structured and unstructured topology. a small collection of axioms of an elementary nature allows one to do much traditional pointfree topology, both on the level of frames or locales, and that of uniform or metric frames. these axioms are sufficiently general to include as examples bounded distributive lattices, $sigma$-frames, $ka...

this paper is a continuation of [uniformities and covering properties for partial frames (i)], in which we make use of the notion of a partial frame, which is a meet-semilattice in which certain designated subsets are required to have joins, and finite meets distribute over these. after presenting there our axiomatization of partial frames, which we call $sels$-frames, we added structure, in th...

Allelic exclusion is established in development through a feedback mechanism in which the assembled immunoglobulin (Ig) suppresses further V(D)J rearrangement. But Ig expression sometimes fails to prevent further rearrangement. In autoantibody transgenic mice, reactivity of immature B cells with autoantigen can induce receptor editing, in which allelic exclusion is transiently prevented or reve...

Murine V kappa-J kappa recombination is characterized by a maintenance of size at the site of recombination and the use of nucleic acids found only in germline sequences. This is in contrast to heavy chain VH-D-JH assembly where random nucleotides are added at the recombination sites to produce considerable size variation, even though the heptamer/nonomer recombination sequences are identical i...

The properties of freestanding tensionless interfaces and membranes at low bending rigidity $\ensuremath{\kappa}$ are dominated by strong fluctuations self-avoidance thus outside the range standard perturbative analysis. We analyze this regime a simple discretized, self-avoiding membrane model on frame subject to periodic boundary conditions use Monte Carlo simulation dynamically triangulated s...

In digital storage media, Video segmentation is one of the popular and important techniques.The challenging problem in digital storage media is video segmentation. In this hybrid video segmentation technique, initially similar shots are segmented. Then subsequently the track frames in every shot are assorted using the extracted objects of every frame which highly mostly reduces the processing t...

results we performed rush on 77 patients. kappa index was 0.71 (p value = 0.000), reflecting acceptable general agreement between initial impression and final diagnosis. for hypovolemic, cardiogenic and obstructive shock, the protocol had an npv above 97% yet it had a lower ppv. for shock with distributive or mixed etiology, rush showed a ppv of 100% but it had low sensitivity. subgroup analysi...

OBJECTIVES Interpretation of stress echocardiography is subjective, and highly dependent on the experience of the interpreter. We sought to evaluate whether a cardiologist without any previous experience in stress echocardiography could adequately learn the skills of interpreting dobutamine stress echocardiograms (DSE) in post-infarct patients, after a period of systematic training. METHODS A...
