An amplicon sequence variant (ASV) is any one of the inferred single DNA sequences recovered from a high-throughput analysis of marker genes. Because these analyses, also called "amplicon reads," are created following the removal of erroneous sequences generated during PCR and sequencing, using ASVs makes it possible to distinguish sequence ...
The ASV continues to host an annual scientific meeting every summer on a selected university campus in the United States or Canada. The society also hosts career and educational information—including an online jobs directory—and received a grant from the Alfred Sloan Foundation to support a website documenting the history of virology.
ASV at sapheno-femoral junction, the "Mickey Mouse sign" The accessory saphenous vein (ASV), either anterior or posterior, is an important GSV collateral frequently responsible for varicose veins located on the anterior and lateral aspect of the thigh. [27] The anterior ASV is more anterior than the ASV and is outside the femoral vessels plan.
The vein can be identified near the saphenous ostium by a typical ultrasonographic image the so-called Mickey mouse sign (the 2 ears will be the GSV and the ASV, the head is the common femoral vein). When the ultrasonography is performed, we can see it running across the anterior face of the thigh in a plan outside the femoral vessels, the GSV ...
In the ASV mode, every breath is synchronized with patient effort if such an effort exists, and otherwise, full mechanical ventilation is provided to the patient. Since the first implementation, ASV has undergone a number of refinements and is available on different ventilator brands under different names.
Conventional active stereo vision (ASV) employs a structured light or laser, however, the stereo matching is performed only for camera-camera correspondences, in the same way as the passive stereo vision. Structured-light stereo (SLS) is a hybrid technique, which utilizes both camera-camera and projector-camera correspondences. [4]

A hypervariable region (HVR) is a location within a sequence where polymorphisms frequently occur. It is used in two contexts: In the case of nucleic acids, an HVR is where base pairs frequently change.
