It is often too expensive to compute and materialize a complete high-dimensional data cube. Computing an iceberg cube, which contains only aggregates above certain thresholds, effective way derive nontrivial multi-dimensional aggregations for OLAP mining.
We propose a method to analyze files categorize their type using efficient 1-gram analysis of binary contents. Our aim is be able accurately identify the true an arbitrary file statistical contents without parsing. Consequently, we may determine if its name does not announce type. The represents each by compact representation call fileprint, effectively simple means representing all members same set models. designed highly so that can inspected with little or no buffering, and on network...
In the search for inhibitors of COVID-19, we have targeted interaction between human angiotensin-converting enzyme 2 (ACE2) receptor and spike binding domain (S1-RBD) SARS-CoV-2. Virtual screening a library natural compounds identified Kobophenol A as potential inhibitor. was then found to block ACE2 S1-RBD in vitro with an IC50 1.81 ± 0.04 μM inhibit SARS-CoV-2 viral infection cells EC50 71.6 μM. Blind docking calculations two sites, molecular dynamics simulations predicted free energies...

Cadmium (Cd), a heavy metal, has harmful effects on animal and human health, it can also obviously induce cell apoptosis. Quercetin (Que) is flavonoid compound with antioxidant other biological activities. To investigate the protective effect of Que Cd-induced renal apoptosis in rats. 24 male SD rats were randomly divided into four groups. They treated as follows: control group was administered orally normal saline (10 ml/kg); Cd injected 2 mg/kg CdCl2 intraperitoneally; + intragastric...
Nitrogen(N), phosphorus(P), and potassium(K) are essential elements that highly deficient during plant growth. Existing diagnostic methods not suitable for rapid diagnosis of large-scale planting areas. Near-ground remote sensing technology based on unmanned aerial vehicle (UAV) sensor is often applied to crop growth condition monitoring agricultural management. It has been proven be used N, P, K content. However, its integrated model less studied. In this study, we collected UAV...
Let \(\mathbb{F}\)q be a finite field with q elements where prime power. Among the classes of constacyclic codes length 5ℓps over we define an equivalence relation such that which have same structure are viewed to equivalent. In this paper classify 5ℓ and give explicit generator polynomials all their dual codes.
Denoising diffusion probabilistic models (diffusion for short) require a large number of iterations in inference to achieve the generation quality that matches or surpasses state-of-the-art generative models, which invariably results slow speed. Previous approaches aim optimize choice schedule over few speed up inference. However, this reduced quality, mainly because process is optimized separately, without jointly optimizing with training process. In paper, we propose InferGrad, model...
Abstract Microplastic fibers account for approximately 40–90% of the total amount microplastics in water environments and sediments. Synthetic textiles are susceptible to aging as a result prolonged exposure moist heat, high-temperature drying, abrasion, resulting release microplastic fibers. However, studies on effects environmental conditions remains limited. Herein, influence wet abrasion from six different synthetic was studied. The results demonstrate that average after undergoing...
Knowledge graph embedding, which aims at learning the low-dimensional representations of entities and relationships, has attracted considerable research efforts recently. However, most knowledge embedding methods focus on structural relationships in fixed triples while ignoring temporal information. Currently, existing time-aware only factual plausibility, smoothness, models interactions between a fact its contexts, thus can capture fine-granularity relationships. This leads to limited...
Abstract Considering the large-span underground excavation subway station of Qingdao Metro Line 6 China for analysis, it is necessary to optimize traditional support system by investigating relevant codes and other tunnel projects. Based on active concept, a high prestressed rock bolt proposed, optimization direction defined apply prestress force bolts, increasing appropriate spacing between supporting arches strengthening at key parts such as large arch foot area, sidewalls junctions....
Traditional Chinese vinegar offers an exceptional flavor and rich nutrients due to its unique solid-state fermentation process, which is a multiple microbial system including various bacteria, fungi viruses. However, few studies on the virus diversities in traditional have been reported. In this paper, using Zhenjiang aromatic as model system, we systemically explored viral communities brewing process of bacterial metagenomes. Results showed that diversity Pei was extensive varied along with...
For separation of the azeotropes n-propanol (NPA) + water and isopropanol (IPA) by liquid–liquid extraction, cyclohexanone was selected as extraction solvent. The equilibrium (LLE) behavior two mixtures (water NPA cyclohexanone) IPA investigated at temperatures 298.15 308.15 K. LLE phase diagrams belong to Treybal's type I. According measured data, distribution ratio factor obtained calculation were used analyze effect cyclohexanone. In addition, NRTL UNIQUAC models fit experimental values...
Three pyridinium-based ionic liquids (ILs) were adopted to extract isopropanol (IPA) from its aqueous mixture for investigating the potential of these ILs in separation a (water + IPA) azeotropic mixture. The liquid–liquid equilibrium values mixtures IPA ILs) was determined at 298.15 K. selectivity and distribution coefficient computed, which indicates that IL n-hexylpyridinium bis(trifluoromethyl sulfonyl)imide displays better extraction effect separate water. Besides, NRTL model applied...
It is often too expensive to compute and materialize a complete high-dimensional data cube. Computing an iceberg cube, which contains only aggregates above certain thresholds, effective way derive nontrivial multi-dimensional aggregations for OLAP mining. In this paper, we study efficient methods computing cubes with some popularly used complex measures, such as average , develop methodology that adopts weaker but anti-monotonic condition testing pruning search space. particular, computation...
