If there is more than the minimum number of keys in the node, simply delete the key from the leaf node and delete the key from the internal node as well. Fill the empty space in the internal node with the inorder successor. Deleting 45 from B-tree If there is an exact minimum nu...
It uses a B-Tree-based data structure to provide secure deletion. We implement our design in full anddoi:10.1007/978-3-319-28778-2_10Joel ReardonSpringer International PublishingC. Cachin, K. Haralambiev, H. Hsiao, and A. Sorniotti. Policy-based secure deletion. In Proc. of CCS, ...
In this paper, we present an algorithm for deleting keys of B*-tree concurrently in the case that the number of to-be-deleted keys is more than a half of the total keys in the tree. The proposed algorithm can be implemented on CREW PRAM model in optimal O(log 2 n + B log B n ...
5. A method comprising: storing, by a storage manager computer, a hierarchy of snapshots S(i), i=1 to N, N being a number of snapshots, for a storage volume; receiving, by the storage manager computer, an instruction to delete a snapshot S(j) in the snapshot; updating, by the st...

A connected graph G is a well-partitioned chordal graph if there exists a partition P of V(G) and a tree T having P as a vertex set such that the following hold. (a) Each part X∈P is a clique in G. (b) For each edge XY∈E(T), there exist X′⊆X and Y′⊆Y such...
In 52%–67% of patients, it is caused by the heterozygous deletion of the distal chromosomal band on the short arm of chromosome 1. Less commonly, it can be caused by other rearrangements (interstitial deletions or complex rearrangements) [5]. Typical craniofacial dysmorphisms, developmental ...
Acute pancreatitis (AP) is a complex inflammatory condition that can lead to systemic inflammatory responses and multiple organ dysfunction. This study investigates the role of Galectin-3 (Gal-3), a β-galactoside-binding lectin, in modulating acquired immune responses in AP. Acute pancreatitis was...
The Node class represents a node in the B+ tree. It has several member variables: keys is a vector of integers that stores the keys contained in the node. parent is a pointer to the parent node of the current node. children is a vector of pointers to the children nodes of the current...
