This paper presents GRAPE, a parallel system for graph computations. GRAPE differs from prior systems in its ability to parallelize existing sequential algorithms as whole. Underlying are simple programming model and principled approach, based on partial evaluation incremental computation. We show that can be "plugged into" with minor changes, get parallelized. As long the correct, their parallelization guarantees terminate correct answers under monotonic condition. Moreover, we MapReduce,...

The incremental problem for a class Q of graph queries aims to compute, given query in 'Q, G, output Q(G) and updates Δ G as input, changes O such that Q(G ⊕ G) = O. It is called bounded if its cost can be expressed polynomial function the sizes Q, reduce computations on possibly big small No matter how desirable, however, our first results are negative: common traversal, connectivity, keyword search pattern matching, their problems unbounded.

Keys for graphs aim to uniquely identify entities represented by vertices in a graph. We propose class of keys that are recursively defined terms graph patterns, and interpreted with subgraph isomorphism. Extending conventional relations XML, these find applications object identification, knowledge fusion social network reconciliation. As an application, we study the entity matching problem that, given G set Σ keys, is all pairs (vertices) identified Σ. show intractable, cannot be...

This paper studies incremental graph partitioning. Given a (vertex-cut or edge-cut) partition C(G) of G and updates ΔG to G, it is compute changes ΔO C(G), yielding the updated such that (a) new load-balanced, (b) its cut size minimum, (c) are also minimum. We show this tri-criteria optimization problem NP-complete, even when has constant size. Worse yet, unbounded, i.e., there exists no algorithm computes with cost determined only by ΔO. approach proposing incrementalize widely-used...

GraphScope is a system and set of language extensions that enable new programming interface for large-scale distributed graph computing. It generalizes previous processing frameworks (e.g. , Pregel, GraphX) databases ( e.g ., Janus-Graph, Neptune) in two important ways: by exposing unified to wide variety computations such as traversal, pattern matching, iterative algorithms neural networks within high-level language; supporting the seamless integration highly optimized engine general...

Moreover, we introduce sampling method reduce big G set H small sample graphs. Given expected support recall bounds, is able...

Saline soils are of great concern globally. Selecting the Yellow River Delta as a model site, influence reclamation on soil salinity and saline quality was investigated. Soil index (SQI) applied to statistically analyze 210 profile samples collected at seven depth layers in 30 sampling sites among native three croplands (peanut, cotton, wheat) May 2020.

Dravet syndrome is a neurological disorder characterized by treatment-resistant polymorphic seizures, primarily caused loss-of-function in the SCN1A gene. To develop an vitro model of this disease, previously study we generated induced pluripotent stem cell line from 10-year-old boy carrying NM_001165963.1:c.5768A to G (Q1923R) mutation SCN1A. Using TALEN-mediated genome editing, have now isogenic control which disease-causing found epilepsy patient iPSCs was corrected, order eliminate...
