background and importance: disk sequestration can be defined as a herniated disk with perforation of the fibrous ring (or outermost annulus fibrosus) and posterior longitudinal ligament with migration of the disk fragment to the epidural space. even after the introduction of high-resolution magnetic resonance imaging (mri), it is still frequently misinterpreted as neoplastic masses. unfortunate...

clustering is one of the known techniques in the field of data mining where data with similar properties is within the set of categories. k-means algorithm is one the simplest clustering algorithms which have disadvantages sensitive to initial values of the clusters and converging to the local optimum. in recent years, several algorithms are provided based on evolutionary algorithms for cluster...

Corneas In article number 2100972, Stefan Giselbrecht and colleagues review existing approaches for bioengineering corneal stromal constructs. There is a high demand bioengineered constructs to overcome global donor shortage, but unfortunately many of these fail clinical trials due poor biomechanical performance. This emphasizes the need more critically design analyze properties in future

Successful mission operations depend on the ability of an organization to collect, manage, analyze, and secure its data. Traditional network frameworks have become less appealing because they rely a “trust but verify” paradigm that does not stand up well against advanced tools techniques modern cyber attackers. The Zero Trust Framework has emerged as logical replacement unfortunately adequately...

The aboveground architecture of Eucalyptus marginata (Jarrah) was investigated in chronosequences of young trees (2.5, 5 and 10 m height) growing in a seasonally dry climate in a natural forest environment with intact soils, and on adjacent restored bauxite mine sites on soils with highly modified A and B horizons above an intact C horizon. Compared to forest trees, trees on restored sites were...
