OBJECTIVE Randomized controlled trials and observational studies have yielded inconsistent results on the effects of metformin on vitamin B12 reduction. We therefore performed a systematic review to analyze the effects of metformin on vitamin B12 concentration. METHODS PubMed, Medline, Embase, and the Cochrane central registry of controlled trials were(More)
A 16-core processor with both message-passing and shared-memory inter-core communication mechanisms is implemented in 65 nm CMOS. Message-passing communication is enabled in a 36 Mesh packet-switched network-on-chip, and shared-memory communication is supported using the shared memory within each cluster. The processor occupies 9.1 and operates fully(More)
AIMS To investigate the characteristics of immunological hypoglycemia associated with insulin antibodies (IAbs) induced by exogenous insulin in Chinese patients with diabetes. METHODS The clinical data of patients with immunological hypoglycemia due to IAbs were retrospectively analyzed by screening patients with diabetes discharged from West China(More)
A market for virtual electricity trade is formed with the basis of hydro-thermal exchange in this paper. Based on the virtual electricity market, each participants formulate their own plan considering the principle of maximizing benefits. This paper sets up an optimal dispatch model for electricity volume exchanged among plants which participate in the(More)
This paper presents a 32-bit vector multiply-accumulate (MAC) architecture capable of supporting multiple precisions. The vector MAC can perform one 32÷32, one 32÷16, two 16÷16, four 8÷8 bit signed/unsigned multiply-accumulate using Booth encoding algorithm and Wallace tree compressing. A reconfigurable Booth encoding array is(More)
This paper proposes a novel multi-core processor with SIMD(Single Instruction Multiple Data) ISA (Instruction Set Architecture) and extended register file for communication applications. To acquire better parallel computing capability, we implement SIMD ISA and increase the number of register file from 32 to 64. 5×5 homogeneous 2-D mesh NoC(More)
