We analyze adequacy of knots and links, utilizing Conway notation, Montesinos tangles and Linknot and KhoHo computer calculations. We introduce a numerical invariant called adequacy number, and compute adequacy polynomial which is the invariant of alternating link families. According to computational results, adequacy polynomial distinguishes (up to mutation) all families of alternating knots a...

BACKGROUND The use of minimally invasive procedures to obtain material for diagnostic purposes has become more prevalent in recent years. As such, there is increased demand for immediate cytologic adequacy assessment of minimally invasive procedures. The array of different locations in which rapid on-site evaluation (ROSE) is expected requires an ever-increasing number of cytology personnel to ...

PURPOSE Determine the characteristics of percutaneous core biopsies that are adequate for a next generation sequencing (NGS) genomic panel. MATERIALS AND METHODS All patients undergoing percutaneous core biopsies in interventional radiology (IR) with samples evaluated for a 46-gene NGS panel during 1-year were included in this retrospective study. Patient and procedure variables were collecte...

BACKGROUND An adequate renal biopsy is essential for diagnosis and treatment of medical renal disease. OBJECTIVE We evaluated two initiatives to improve adequacy of renal biopsy samples at our centre. DESIGN Retrospective determination of renal biopsy adequacy. SETTING Queen Elizabeth II Health Sciences Centre. PATIENTS Patients undergoing medical renal biopsies. MEASUREMENTS Renal bi...

Pension systems are usually evaluated from the perspective of two basic criteria: pension adequacy and financial sustainability. The first criterion concerns the level of pension benefits and protection of the elderly from poverty. The second criterion applies to financial liquidity. This paper is primarily of methodological nature. We discuss the problem of measuring pension adequacy, focusing...
