Adjacency Matrix: An adjacency matrix is a V x V binary matrix A (a binary matrix is a matrix in which the cells can have only one of two possible values - either a 0 or 1). Element Ai,j is 1 if there is an edge from vertex i to vertex j else Ai,j is 0. The adjacency matrix can also be modified for the weighted graph in which instead of storing 0 or 1 in Ai,j we will store the weight or cost of the edge from vertex i to vertex j. In an undirected graph, if Ai,j = 1 then Aj,i = 1. In a directed graph, if Ai,j = 1 then Aj,i may or may not be 1. Adjacency matrix providers constant time access (O(1) ) to tell if there is an edge between two nodes. Space complexity of adjacency matrix is O(V2).

This recursive nature of DFS can be implemented using stacks. The basic idea is that we pick a starting node and push all its adjacent nodes into a stack. Then, we pop a node from stack to select the next node to visit and push all its adjacent nodes into a stack. We keep on repeating this process until the stack is empty. But, we do not visit a node more than once, otherwise we might end up in an infinite loop. To avoid this infinite loop, we will mark the nodes as soon as we visit it.
A graph is said to be disconnected if it is not connected, i.e., if there exist two nodes in the graph such that there is no edge between those nodes. In an undirected graph, a connected component is a set of vertices in a graph that are linked to each other by paths. Consider an example given in the diagram. As we can see graph G is a disconnected graph and has 3 connected components. First connected component is 1 -> 2 -> 3 as they are linked to each other. Second connected component 4 -> 5 and third connected component is vertex 6. In DFS, if we start from a start node it will mark all the nodes connected to start node as visited. So if we choose any node in a connected component and run DFS on that node it will mark the whole connected component as visited. So we will repeat this process for other connected components.
Its a traversing algorithm, where we start traversing from selected node (source or starting node) and traverse the graph layerwise which means it explores the neighbour nodes (nodes which are directly connected to source node) and then move towards the next level neighbour nodes. As the name suggests, we move in breadth of the graph, i.e., we move horizontally first and visit all the nodes of the current layer and then we move to the next layer.Consider the diagram below:
In the above diagram, starting from 0, we will visit its children 1, 2, and 3 and store them in the order they get visited. So that after visiting all the vertices of current layer, we can visit the children of 1 first(that are 4 and 5), then of 2 (that are 6 and 7) and then of 3(that is 7) and so on.
As in the above diagram, starting from source node, to find the distance between 0 and 1, if we do not follow BFS algorithm, we can go from 0 to 2 and then to 1. It will give the distance between 0 and 1 as 2. But the minimum distance is 1 which can be obtained by using BFS.
edges[ v ] [ i ] is an adjacency list that will exists in pair form i.e edges[ v ][ i ].first will contains the number of node to which v is connected and edges[ v ][ i ].second will contain the distance between v and edges[ v ][ i ].first . Q is double ended queue.distance is an array where, distance [ v ] will contain the distance from start node to v node.Initially define distance from source node to each node as infinity.
The root cause of this issue is a long-standing bug in Moby. This will be resolved in a future release. Be advised that support for alternate OCI runtimes is a new feature and that similar issues may be discovered as more users start exercising this functionality.
Warning; spoilers ahead. The plot involves Neo (Keanu Reeves), a mild-mannered software author by day, a feared hacker by night. He's recruited by a cell of cyber-rebels, led by the profound Morpheus (Laurence Fishburne) and the leather-clad warrior Trinity (Carrie-Anne Moss). They've made a fundamental discovery about the world: It doesn't exist. It's actually a form of Virtual Reality, designed to lull us into lives of blind obedience to the "system." We obediently go to our crummy jobs every day, little realizing, as Morpheus tells Neo, that "Matrix is the wool that has been pulled over your eyes--that you are a slave." The rebels want to crack the framework that holds the Matrix in place, and free mankind. Morpheus believes Neo is the Messianic "One" who can lead this rebellion, which requires mind power as much as physical strength. Arrayed against them are the Agents, who look like Blues Brothers. The movie's battles take place in Virtual Reality; the heroes' minds are plugged into the combat. (You can still get killed, though: "The body cannot live without the mind"). "Jacking in" like this was a concept in "Strange Days" and has also been suggested in novels by William Gibson ("Idoru") and others. The notion that the world is an artificial construction, designed by outsiders to deceive and use humans, is straight out of "Dark City." Both of those movies, however, explored their implications as the best science fiction often does. "Dark City" was fascinated by the Strangers who had a poignant dilemma: They were dying aliens who hoped to learn from human methods of adaptation and survival.

Light micrograph study of L. cyprinacea infesting goldfish aquaria after treatment with star anise (Illicium verum); showing destruction of the cuticle. (A): normal cuticle; (B): destructed cuticle with release of the eggs.
In the C. auratus skin infested by L. cyprinacea, IL-6 was 15-fold more upregulated than in the control non-infested fish. Concerning the expression of mRNA of the treated fish using star anise, IL-6 was 20-fold upregulated in the first week after treatment, then declined after 3 weeks of treatment to 10-fold more than in the control non-infested fish. All genes were expressed significantly higher than the control non-infested group (4.20 0.00) (p = 0.0001) (Figure 6).
In the C. auratus skin infested by L. cyprinacea, TNF-α was 18-fold more upregulated than in the control non-infested fish. Concerning the expression of mRNA of the treated fish using star anise, TNF- α was 23-fold upregulated in the first week after treatment, then declined after 3 weeks of treatment to 12-fold more than in control non-infested fish. All genes were expressed significantly higher than the control non-infested group (3.50 0.00) (p = 0.0001) (Figure 7).
In this study, star anise was evaluated for antiparasitic activity in vitro and in vivo against L. cyprinacea, with a good result in low concentration where the LC50 was 12.5 μg/mL for a 2 h exposure period; or for 25 μg/mL for 1 h exposure. This study uses direct contact and fumigation approaches such as the previous study on arthropods (Drosophila melanogaster) with mortality using star anise in vitro. The main component of the methanol extract was (E)-anethole. The 5-day LD50 of (E)-anethole in D. melanogaster was a diet containing 0.2 mg/mL [20,58]. In addition, the insecticidal effect of (E)-anethole was demonstrated versus adult Blattella germanica [40] at 0.159 mg/cm2 one and three days post-treatment. (E)-anethole induced an 80.3 percent mortality in a filter paper diffusion approach, whereas hydramethylnon (positive control) caused 93.3 percent mortality.
Our results revealed that the proinflammatory cytokines (IL-1β, IL-6, and TNF-α) were increased during the infestation with L. cyprinacea in goldfish; these findings are similar to those recorded by Tu et al. [43], which applied to goldfish infested with Gyrodactylus kobayashii and the cytokines were again elevated during treatment with the star anise. These results are supported by those recorded by Vaseeharan and Thaya [63]. They stated that essential oils are also immunostimulants. Zhang et al. [64] and Sarhadi et al. [65] stated that feeding Cyprinus carpio with Origanum vulgare and Artemisia annua for eight weeks improved both the immunological and antioxidant qualities, which increased IL-1β, as well as resistance to A. hydrophila. EOs boosted IL-1β and IL-10 transcription while decreasing TNF-α and transforming growth factor (TGF-β).
Besides the beneficial uses of star anise in therapy for different diseases, there are several case reports relating to juveniles recording neurotoxicity and hepatotoxicity, such as those recorded in [66,67,68]. However, those investigations were in juveniles and employed homemade herbal remedies; though several investigations and extensive research were completed in relation to this plant to prove these case reports. In addition, this plant gave good results in relation to different parasites. 2ff7e9595c
