This paper discusses the bias problem when estimating population size of big data such as online social networks (OSN) using uniform random sampling and simple walk. Unlike traditional estimation where sample is not very small relative to size, in data, a already large costly obtain. We point out that samples are used, there no longer negligible. shows analytically can be approximated by reciprocal number collisions; thereby, correction estimator introduced. The result further supported both...
SMALL AUXIN-UP RNAs (SAURs) comprise the largest family of early auxin response genes. Some SAURs have been reported to play important roles in plant growth and development, but their functional relationships with signaling remain unestablished. Here, we report Arabidopsis (Arabidopsis thaliana) SAUR15 acts downstream factors ARF6,8 ARF7,19 regulate signaling-mediated lateral root (LR) adventitious (AR) formation. The loss-of-function mutant saur15-1 exhibits fewer LRs ARs. By contrast,...
Pore-forming peptides are promising antimicrobial and anticancer agents due to their membrane selectivity biodegradability. Our prior work identified peptide M159, which permeabilized synthetic phosphatidylcholine liposomes without mammalian cell toxicity. Here, we report that the D-type variant (D-M159) induces apoptosis in HeLa cells under starvation. To explore its mechanism, analyzed D-M159 cytotoxicity, intracellular uptake, apoptotic pathways via flow cytometry, confocal microscopy,...
This paper proposes to use simple random walk, a sampling method supported by most online social networks (OSN), estimate variety of properties large OSNs. We show that due the scale-free nature OSNs estimators derived from walk scheme are much better than uniform sampling, even when samples available disregarding notorious high cost obtaining samples. The first harmonic mean average degree accurate estimation leads discovery other properties, such as population size, heterogeneity degrees,...
Zygophyllum xanthoxylum is a succulent xerophyte with remarkable tolerance to diverse abiotic stresses. Previous studies have revealed important physiological mechanisms and identified functional genes associated stress tolerance. However, knowledge of the regulatory conferring in this species poorly understood.Here, we present comprehensive analysis based on transcriptome Z. roots exposed osmotic salt treatments. Significant changes were observed transcripts related known obscure...
Abstract SARS-CoV-2 is continuing to evolve and diversify, with an array of various Omicron sub-lineages, including BA.5, BA.2.75, BN.1, BF.7, BQ.1, BQ.1.1, XBB XBB.1.5, now circulating globally at recent time. In this study, we evaluated the neutralization sensitivity a comprehensive panel subvariants sera from different clinical cohorts, individuals who received homologous or heterologous booster vaccinations, vaccinated people had Delta BA.2 breakthrough infection in previous waves,...
Neu1 is a sialidase enzyme that plays crucial role in the regulation of glycosylation variety cellular processes, including signaling and inflammation. In recent years, numerous evidence has suggested human NEU1 also involved pathogenesis various respiratory diseases, lung infection, chronic obstructive pulmonary disease (COPD), asthma, fibrosis. This review paper aims to provide an overview current research on diseases.
In a traditional virtualized cloud environment, using asynchronous I/O in the guest file system and synchronous host to handle an user disk write exhibits several drawbacks, such as performance disturbance among different guests consistency maintenance across failures. To improve these issues, this paper introduces novel model for called HypeGear, where uses operations deal with request performs data hard disk. A prototype is implemented on Xen hypervisor our experimental results verify that...
Memory object caching systems, such as Memcached and Redis, have been proved to be a simple high-efficient middleware for improving the performance of Internet Things (IoT) devices querying database in cloud. However, its guarantee is built on fact that target data, queried by IoT device, will accessed many times hit system. Therefore, when system handling unrepeated queries, it usually presents suboptimal performance, which greatly impairs efficiency real-time data processing devices. To...
Methylprednisolone pulse therapy (MPPT), as a public recognized of spinal cord injury (SCI), is doubted recently, and the exact mechanism MP on SCI unclear. This study sought to investigate effect SCI. We examined in model vivo an LPS induced vitro. found that administration produced increase Basso, Beattie, Bresnahan scores motor neurons counts injured rats. Besides number activated microglia was apparently reduced by vivo, Beclin-1 dependent autophagic cell death model. At same time,...
Drought and salinity can result in cell dehydration water unbalance plants, which seriously diminish plant growth development. Cellular homeostasis maintained by aquaporin is one of the important strategies for plants to cope with these two stresses. In this study, a stress-induced aquaporin, ZxPIP1;3, belonging PIP1 subgroup, was identified from succulent xerophyte Zygophyllum xanthoxylum. The subcellular localization showed that ZxPIP1;3-GFP located plasma membrane. overexpression ZxPIP1;3...
The relational database service in cloud usually achieves energy efficiency by using virtualization technology, which it consolidates multiple independent systems into a single physical machine while enforcing the hardware-level isolation among them. However, disk I/O performance is inevitably hurt due to resource contention on shared device. We propose VMSQL, novel model for virtualized management system (RDBMS). VMSQL has two innovations over original of systems. First, enforces...
Advanced microwave technologies constitute the foundation of a wide range modern sciences, including quantum computing, photonics, spintronics, etc. To facilitate design chip-based devices, there is an increasing demand for state-of-the-art microscopic techniques capable characterizing near-field distribution and performance. In this work, we integrate Josephson junctions onto nano-sized quartz tip, forming highly sensitive mixer on-tip. This allows us to conduct spectroscopic imaging...
Modern local persistent memory (PM) file systems often rely on CPU-based copying for data transfer between DRAM and PM, resulting in significant CPU resource consumption. While some nascent explore DMA (direct access) as an alternative improved efficiency, the intricacies trade-offs remain obscure. This paper investigates feasibility of PM I/O argues that it is not a straightforward replacement methods. Two key limitations hinder direct adoption: poor performance small limited bandwidth. To...

Abstract Deploying user data or programs in cloud risks divulging their privacy because the cloud‐side supervisors, such as system administrators, can leverage higher privilege to snoop data. Based on trusted execution environment (TEE) technology, Intel Software Guard eXtension (SGX) is a practical remedy privacy, which employs hardware‐assisted enclave wrap sensitive data, preventing them from disclosure. However, application performance hurt due CPU‐expensive and frequent operations...
Due to the expected near DRAM performance, popular async I/O systems are disabled on local persistent memory (PM) file systems, which instead use pseudo-async path (namely sync one), serve (AIO) requests of applications. This paper first identifies performance shortcomings this kind method and argues necessity applying real PM device. Then, proposes PM-AIO, a general create an effective systems. PM-AIO leverages kernel-level threads achieve asynchronism concurrency. We implement in...
