\beginabstract The trend in the DBMS market is to migrate cloud for elasticity, high availability, and lower costs. traditional, monolithic database architecture difficult meet these requirements. With development of high-speed network new memory technologies, disaggregated data center has become a reality: it decouples various components from servers into separated resource pools (e.g., compute, memory, storage) connects them through network. next generation native databases should be...
It is challenging for cloud-native relational databases to meet the ever-increasing needs of scaling compute and memory resources independently elastically. The recent emergence disaggregation architecture, relying on high-speed RDMA network, offers opportunities build cost-effective elastic databases. There exist proposals let unmodified applications run transparently disaggregated systems. However, running database kernel atop such experiences notable performance degradation time-consuming...
In response to the issue of strong swirl and flow distortion at inlet high-pressure turbine, this paper focuses on research method combustor–turbine coupling conducts relevant aerodynamic mechanism turbine first stage nozzle guide vane (NGV) under different number generated by generator. The results indicate that coefficient total pressure loss (ξ) NGV in non-coupled group increases with increase intensity, while coupled shows a macroscopic decreasing trend intensity After swirling enters...
In this paper, we propose a graph-based kinship reasoning (GKR) network for verification, which aims to effectively perform relational on the extracted features of an image pair. Unlike most existing methods mainly focus how learn discriminative features, our method considers compare and fuse feature pair reason about kin relations. The proposed GKR constructs star graph called where each peripheral node represents information comparison in one dimension central is used as bridge...
:Quality assurance in modern higher education is both an accountability-oriented ideology and a technological method. It has also evolved into increasingly rationalist professionalized power mechanism. Its advocacy of compliance, mythology, imbalance between responsibility are inherent disadvantages quality at present. To sustainably improve quality, the current concern must change from to culture. We should reflect on innovate traditional education. At same time, it necessary build holistic...
The recent emergence of commodity persistent memory (PM) hardware has altered the landscape storage hierarchy. It brings multi-fold benefits to database systems, with its large capacity, low latency, byte addressability, and persistence. However, PM not been incorporated into popular disaggregated architecture cloud-native databases.
Primary-secondary databases often have limited write throughput as they rely on a single primary node. To improve this, some systems use shared-nothing architecture for scalable multi-primary clusters. However, these face performance issues due to distributed transaction overheads. Recently, shared-storage-based cloud-native emerged avoid issues, but still struggle with in high-conflict scenarios, expensive conflict resolution and inefficient data fusion.
Cloud computing is on the rise, which promotes new breeds of database systems to accommodate cloud environment. The development cloud-native databases reveals three trends. One adoption multi-datacenter (DC) deployment survive downtime any single site. Another separation computation and storage resources achieve higher elasticity scalability. last support HTAP eliminate data redundancy system complexity from heterogeneous databases. To cater these trends, we design a distributed relational...
Incorporating humic acid (HA) into phosphate fertilizers to produce HA-enhanced (HAPs) can improve the migration and availability of fertilizer-derived phosphorus (P) in soil. However, optimal proportion HA remains inconsistent. Here, we investigated effects HAPs with different proportions (0.1–10% w/w) on water-soluble P fixation rate, migration, transformation, soil microorganisms, analyzed main forms HAP using Fourier transform infrared spectroscopy nuclear magnetic resonance...
Ghost imaging (GI) is an unconventional method that reconstructs the object information via light-intensity correlation measurements. However, at present, field of view (FOV) this limited to illumination range light patterns. To enlarge FOV GI efficiently, we propose omnidirectional system (OGIS) can achieve a 360° only addition curved mirror. The OGIS features retina-like annular patterns designed as log-polar structure and obtain undistorted unwrapping-free panoramic images with uniform...
A classic design of cloud-native databases adopts an architecture that consists one read/write (RW) node and or more read-only (RO) nodes. In such a design, the propagation write-ahead logs (WALs) from RW to RO node(s) is typically performed asynchronously. Consequently, system designers either have accept loose consistency guarantee, where read may return stale data, tolerate significant performance degradation in terms latency, as it then needs wait for log be propagated applied. Most...
Humic acid (HA)-enhanced urea (HAU) is the top-selling efficiency-enhanced in China. Comprehensive investigation into structure and efficacy of HA complex formation with (HACU) - main reaction product during HAU's production required to clarify mechanism between urea, provide guidance for development high-efficiency HAU.HACU showed discrepant structural compositional features from raw HA. Nitrogen (N) content HACU was 7.3 times greater than that Several high-resolution analytical methods a...
Motion deblurring is a critical ill-posed problem that important in many vision-based robotics applications. The recently proposed event-based double integral (EDI) provides theoretical framework for solving the prob-lem with event camera and generating clear images at high frame-rate. However, original EDI mainly designed offline computation does not support real-time requirement In this paper, we propose fast EDI, an efficient implementation of can achieve online on single-core CPU...
The reforms on the modern university academy system that preserve certain elements of China's ancient traditional academies have currently encountered a series difficulties. crux problem is living and educational spaces were integrated in academy, while school education institution has separated two. So only inherits spatial form academy. To resolve these difficulties requires creatively preserving spirit rather than systemically innovating institutions such as advisor system, general...
18F-FDG PET/CT is recommended for staging and response assessment in FDG-avid lymphomas, such as HL DLBCL. But evidence of regarding T-cell lymphomas (TCLs) was limited. In this retrospective study, we conducted survival analysis using interim 51 TCLs patients. were reported the Deauville 5-point score (DS) ΔSUVmax. univariate analysis, I-PET/CT had a significant prognostic value outcomes based on DS (p < .001 progression-free (PFS), p = .010 overall (OS)) ΔSUVmax PFS, .023 OS). multivariate...
Unlike traditional optical imaging schemes, computational ghost (CGI) provides a way to reconstruct images with the spatial distribution information of illumination patterns and light intensity collected by single-pixel detector or bucket detector. Compared stationary scenes, relative motion between target system in dynamic scene causes degradation reconstructed images. Therefore, we propose time-variant retina-like method for axially moving targets. The illuminated are specially designed...
