Beforeyou can determine the replacement tire that best fits your lifestyle, you must first find the tire that properly fits your vehicle. Identifying the proper replacement tire size is more than merely measuring the radius. It considers factors such as aspect ratio, load index, speed rating, metric type and more.

Background & aims: The evolution of complicated pediatric Crohn's disease (CD) in the era of anti-tumor necrosis factor (aTNF) therapy continues to be described. Because CD progresses from inflammatory to stricturing (B2) and penetrating (B3) disease behaviors in a subset of patients, we aimed to understand the risk of developing complicated disease behavior or undergoing surgery in relation to aTNF timing and body mass index z-score (BMIz) normalization.

Methods: Multicenter, 5-year longitudinal data from 1075 newly diagnosed CD patients were analyzed. Descriptive statistics, univariate and stepwise multivariate Cox proportional hazard regression (CPHR), and log-rank analyses were performed for risk of surgery and complicated disease behaviors. Differential gene expression from ileal bulk RNA sequencing was correlated with outcomes.

Conclusions: aTNF exposure up to 3 months from diagnosis may reduce B2 progression. In addition, lack of BMIz normalization within 6 months of diagnosis is associated with increased surgery risk and a proinflammatory transcriptomic profile.

JanusGraph supports two different kinds of indexing to speed up queryprocessing: graph indexes and vertex-centric indexes (a.k.a. relation indexes).Most graph queries start the traversal from a list of vertices or edges that areidentified by their properties. Graph indexes make these globalretrieval operations efficient on large graphs. Vertex-centric indexesspeed up the actual traversal through the graph, in particular whentraversing through vertices with many incident edges.

Graph indexes are global index structures over the entire graph whichallow efficient retrieval of vertices or edges by their properties forsufficiently selective conditions. For instance, consider the followingqueriesg.V().has('name', 'hercules')g.E().has('reason', textContains('loves'))

The first query asks for all vertices with the name hercules. Thesecond asks for all edges where the property reason contains the wordloves. Without a graph index answering those queries would require afull scan over all vertices or edges in the graph to find those thatmatch the given condition which is very inefficient and infeasible forhuge graphs.

JanusGraph distinguishes between two types of graph indexes:composite and mixed indexes. Composite indexes are very fast andefficient but limited to equality lookups for a particular,previously-defined combination of property keys. Mixed indexes can beused for lookups on any combination of indexed keys and support multiplecondition predicates in addition to equality depending on the backingindex store.

Both types of indexes are created through the JanusGraph managementsystem and the index builder returned byJanusGraphManagement.buildIndex(String, Class) where the firstargument defines the name of the index and the second argument specifiesthe type of element to be indexed (e.g. Vertex.class). The name of agraph index must be unique. Graph indexes built against newly definedproperty keys, i.e. property keys that are defined in the samemanagement transaction as the index, are immediately available. The sameapplies to graph indexes that are constrained to a label that is createdin the same management transaction as the index. Graph indexes builtagainst property keys that are already in use without being constrainedto a newly created label require the execution of a reindex procedure to ensure that the index contains all previouslyadded elements. Until the reindex procedure has completed, the indexwill not be available. It is encouraged to define graph indexes in thesame transaction as the initial schema.

In the absence of an index, JanusGraph will default to a full graphscan in order to retrieve the desired list of vertices. While thisproduces the correct result set, the graph scan can be veryinefficient and lead to poor overall system performance in aproduction environment. Enable the force-index configuration optionin production deployments of JanusGraph to prohibit graph scans.

First, two property keys name and age are already defined. Next, asimple composite index on just the name property key is built.JanusGraph will use this index to answer the following query.g.V().has('name', 'hercules')

Also note, that composite graph indexes can only be used for equalityconstraints like those in the queries above. The following query wouldbe answered with just the simple composite index defined on the namekey because the age constraint is not an equality constraint.g.V().has('name', 'hercules').has('age', inside(20, 50))

Composite indexes do not require configuration of an external indexingbackend and are supported through the primary storage backend. Hence,composite index modifications are persisted through the same transactionas graph modifications which means that those changes are atomic and/orconsistent if the underlying storage backend supports atomicity and/orconsistency.

Mixed indexes retrieve vertices or edges by any combination ofpreviously added property keys. Mixed indexes provide more flexibilitythan composite indexes and support additional condition predicatesbeyond equality. On the other hand, mixed indexes are slower for mostequality queries than composite indexes.

The example above defines a mixed index containing the property keysname and age. The definition refers to the indexing backend namesearch so that JanusGraph knows which configured indexing backend itshould use for this particular index. The search parameter specifiedin the buildMixedIndex call must match the second clause in theJanusGraph configuration definition like this: index.search.backendIf the index was named solrsearch then the configuration definitionwould appear like this: index.solrsearch.backend.

The mgmt.buildIndex example specified above uses text search as itsdefault behavior. An index statement that explicitly defines the indexas a text index can be written as follows:mgmt.buildIndex('nameAndAge',Vertex.class).addKey(name,Mapping.TEXT.asParameter()).addKey(age,Mapping.TEXT.asParameter()).buildMixedIndex("search")

See Index Parameters and Full-Text Search for more information on text and stringsearch options, and see the documentation section specific to theindexing backend in use for more details on how each backend handlestext versus string searches.

If the added key is defined in the same management transaction, it willbe immediately available for querying. If the property key has alreadybeen in use, adding the key requires the execution of a reindex procedure to ensure that the index contains all previouslyadded elements. Until the reindex procedure has completed, the key willnot be available in the mixed index.

When adding a property key to a mixed index - either through the indexbuilder or the addIndexKey method - a list of parameters can beoptionally specified to adjust how the property value is mapped into theindexing backend. Refer to the mapping parametersoverview for a complete list of parameter types supportedby each indexing backend.

Mixed indexes support ordering natively and efficiently. However, the property key used in the order().by() method must have been previously added to the mixed indexed for native result ordering support. This is important in cases where the the order().by() key is different from the query keys. If the property key is not part of the index, then sorting requires loading all results into memory.

Label restrictions similarly apply to mixed indexes. When a compositeindex with label restriction is defined as unique, the uniquenessconstraint only applies to properties on vertices or edges for thespecified label.

A composite index requires all fields to be present, while a mixed index only needs at least one field to be present. For example, say you have a composite index with key1 and key2, a mixed index with key1 and key3. If you add a vertex with only property key1, then JanusGraph will create a new mixed index entry but not a composite index entry.

Vertex-centric indexes, also known as Relation indexes, are local indexstructures built individually per vertex. They are stored together with edgesand properties in edgeStore. There are two types of vertex-centric indexes,edge indexes and property indexes.

In large graphs vertices can have thousands of incident edges.Traversing through those vertices can be very slow because a largesubset of the incident edges has to be retrieved and then filtered inmemory to match the conditions of the traversal. Vertex-centric indexescan speed up such traversals by using localized index structures toretrieve only those edges that need to be traversed.
