We report the synthesis and structural characterization of a 2D metal–organic framework with AB-packing layers, [Co2(pybz)2(CH3COO)2]·DMF (Co2, pybz= 4-(4-pyridyl)benzoate), containing stable (4,4)-grid network fabricated by paddle-wheel nodes, ditopic pybz, acetate ligands. After removal guest, layer structure is retained but reorganized into an ABCD packing mode in activated phase (Co2a). Consequently, intralayer square windows (7.2 × 5.0 Å2) close, while interlayer separation decreased...

Objectives This study aimed to identify the epidemiology, clinical characteristics, aetiology and seasonality of sporadic infectious diarrhoea in adults Shanghai. Setting was based on a city-wide, active continuous hospital-based surveillance network established by Shanghai Municipal Center for Disease Control Prevention. There were 22 sentinel hospitals all 16 districts (9 primary-level hospitals, 6 secondary-level 7 tertiary-level hospitals) which selected using probability proportionate...

As the resource density of cloud servers increases, providers deploy hundreds VMs concurrently on a single server, requiring high-performance, scalable, flexible and high-density I/O virtualization method. Hardware assisted such as device pass-through with SR-IOV can achieve near-native performance, however, at expense flexibility limited count. Traditional software-based systems tend to dedicate additional computing cores for higher but suffer from critical scalability problems especially in cloud.

High performance networking interface cards (NIC) have become essential devices in commercial cloud computing environments. Therefore, efficient and scalable I/O virtualization is one of the primary challenges on virtualized platforms. Single Root Virtualization (SR-IOV) a network technology that eliminates overhead redundant data copies virtual switches through direct order to achieve nearly natural performance. However, SR-IOV still suffers from serious problems due high for processing...

Network coding provides a powerful mechanism for improving performance of wireless networks. In this paper, we present an analytical approach end-to-end delay analysis in networks that employ inter-session coding. Prior work on network mainly focuses the throughput overall network. Our aims to analyze each flow The theoretical basis our is calculus. order apply calculus coding, address three specific problems: identifying traffic flows, characterizing broadcast links, and measuring...

Protecting the customer's SSL private key is paramount issue to persuade website owners migrate their contents onto cloud infrastructure, besides advantages of infrastructure in terms flexibility, efficiency, scalability and elasticity. The emerging Keyless solution retains on-premise custody customers' keys on own servers. However, it suffers from significant performance degradation limited scalability, caused by long distance connection Key Server for each new coming end-user request....

Objective assess clinical and complication rates treatment fractures after closed manual reduction. Design, Setting, Participants This 12-week, multicenter, open-label, analyst-blinded randomized trial (comprising a 6-week intervention followed by observational phase) was carried out from December 3, 2021, to March 10, 2023, among 110...

With in-memory key-value caches such as Redis and Memcached being a key component for many systems to improve throughput reduce latency, cloud have been widely adopted small companies deploy their own cache systems. However, data security is still major concern, which affects the adoption of caches. Tenant's stored in multi-tenant environment faces threats from both co-located other tenants, well untrusted provider.

With the emergence of Long Term Evolution (LTE) technology, LTE based VoIP services are gaining more and popularity in these days. Voice over (VoLTE) is a multimedia service on All-IP network, which was initially introduced commercialized by Korea telecommunication companies 2012. As subscribers use VoLTE service, traffic volume increases, this may turn lower down quality; therefore to preserve QoS we need periodically monitor among traffic, perform appropriate actions network. To be first...

Hosting content delivery networks (CDNs) on clouds has the potential to improve performance as resources and caches can be placed closer subscribers. However, avoiding data leakage over an untrusted public cloud is critical, especially for sensitive such SSL private key. The popular Keyless solution allows owners retain on-premise custody of keys their own key servers, but this likely causes bottlenecks impedes elasticity CDNs. This paper describes a novel management system, named STYX,...
