A simple silver salt (AgOAc)-catalyzed anti-Markovnikov-selective hydroboration of alkenes, 1,3-dienes, and alkynes with pinacolborane (HBpin) has been described. This strategy provides an efficient practical method to access various alkyl-, allyl-, (E)-alkenylboronate esters in good excellent yields regio- stereoselectivity under ligand- base-free conditions.

Purpose As national legislation, federated services, institutional policies and research service arrangements may differ, data stewardship programs be organized differently in higher education institutions across the world. This work seeks to elaborate picture of different running environments. Design/methodology/approach Utilizing a case study design, this described three distinct from Purdue University (United States), Delft Technical (Netherlands) Aalto (Finland). In addition,...

To explore the effect of general anesthesia combined with epidural and patient-controlled analgesia on incidence post-operative cognitive dysfunction (POCD) in elderly patients. A total 100 patients gastric cancer, who underwent radical gastrectomy Yan'an People's Hospital from March 2012 to 2015, were randomly divided into 3 groups: a intravenous (PCIA) (Group I, n=35), PCIA II, n=30), (PCEA) III, n=35). There was no significant difference age, gender, body mass index (BMI), length...

In the peer to (P2P) lending platform, investors hope maximize their return while minimizing risk through a comprehensive understanding of P2P market. A low and stable average default rate across all borrowers denotes healthy market provides more confidence in promising investment. Therefore, having powerful model describe trend is crucial. Different from previous studies that focus on modeling at individual level, this paper, we are first comprehensively explore monthly aggregative level...

In this paper, we develop a queue-aware long-term energy-efficient optimization scheme for cell-free multiple-input multiple-output (CF-MIMO) systems in the ultra-reliable and low-latency communication (URLLC) scenario. Considering coordinated multi-point (CoMP) hybrid orthogonal scheduling scheme, formulate stochastic problem to maximize utility maintain network stability. By introducing Lyapunov framework, is decomposed into sequence of subproblems. Then, propose an energy-efficiency (EE)...

The fast developing mobile technology and the lack of practices make it difficult to design information services satisfying quality within allocated time budget. One difficulties is unstable environment in which users accessing these find themselves. Information used on a personal computer connected Internet with wired line are nowadays quite stable. However, use device by or wireless network still vulnerable. usage even more since distracted when they move, an that might be unfamiliar,...

Purpose Due to the complexity of digital services, companies are increasingly forced offer their services “in permanent beta”, requiring continuous fine-tuning and updating. Complexity makes it extremely difficult predict when where next service disruption will occur. The authors examine what this means for performance measurement in supply chains. Design/methodology/approach use a mixed-method research design that combines longitudinal case study European TV provider system dynamics...

Simulation exercises are fundamental for building knowledge, skills and capacities of participants to effectively address challenges in crisis management. A key element emergency response the work with information support decision-making processes. However, not only exercise dealing management (IM), but those controlling directing as well. Dynamic environments require IM -for directors- optimize training opportunities. Despite common challenges, activities directors have so far been...

Institutional Repositories (IRs) are becoming important library resources, and increasing utilization of IR content is a key to building sustainable IRs. The China Agricultural University Library has developed proven, successful service delivery model for IRs, through multi-themed, multi-layered organization content, modular publishing, closely matching user requests, as described in this paper

Three novel gallium phosphites, Ga-3, Ga-2, and Ga-1, have been hydrothermally synthesized via the commercial 4-dimethylaminopyridine (DMAP) reagent serving as a template in Ga-3 Ga-1 ligand Ga-2. These main-group-metal phosphites present different topology from first 3D framework containing extra-large 14-ring (14R) channel (Ga-3) then second 2D organic–inorganic hybrid layer (Ga-2) to 1D phosphite chain (Ga-1). The structure detail of three compounds, examined by single-crystal X-ray...

Objective To summarize the construction, upgrading process and clinical application of prostate cancer database (PC–Follow). Methods From September 2008 to December 2014, we designed two versions off–line PC–Follow databases based on Microsoft Access support follow–up research in patients. Then, order achieve unified management data import multi–center research, further upgraded a browser/server (B/S) schema web database. After upgrade, simulated operation pattern was adopted transfer...
