Most previous investigations on interference effects of tall buildings under wind actions focused on the wind induced interference effects between two buildings, and the interference effects of three or more buildings have seldom been studied so far due to the huge workload involved in experiments and data processing. In this paper, mean and dynamic force/response interference effects and peak wind pressure interference effects of two and three tall buildings, especially the three-building configuration, are investigated through a series of wind tunnel tests on typical tall building models using high frequency force balance technique and wind pressure measurements. Furthermore, the present paper focuses on the effects of parameters, including breadth ratio and height ratio of the buildings and terrain category, on the interference factors and derives relevant regression results for the interference factors.

A study of approach wind flow simulation of the low-rise building was performed in a boundary layer wind tunnel at Shantou University. Three kinds of experimental configuration are employed to simulate the suburban terrain. The characteristics of three types of simulated flow are presented. The wind tunnel testing of low-rise building, 1 : 30 geometrical scale model of the Texas Tech University test building was performed in the simulated flow. The model and full-scale pressure coefficients are presented for high-turbulence boundary layer flow. The comparison of the scale model and full-scale model building point pressure exhibits a good agreement for most of the pressure taps.

A study of approach aerodynamic shape optimization of a high-rise building, Shenzhen Kingkey financial tower, was performed in a boundary layer wind tunnel at Shantou University. Building shape has significant effects on the wind load forcing on the structure. The peak overturning moments about x-axis and the peak accelerations at the top of building are presented in this paper. Compared with the experimental results, one case is considered as the optimal case for structural design.

In Beijing communities, the prevalence of hypertension is high and the blood pressure control rate is low in patients with type 2 diabetes. [...]the need for multi-risk factor control and effective community-based management for patients with type 2 diabetes and hypertension is clear. [...]a significant reduction in the FRS after 48 months of follow-up was found in the high Framingham risk strata. [...]it is likely that a multifactorial intervention for CVD risk factors will have a positive, long-term effect on the FRS in type 2 diabetes patients in the community, especially those in the high Framingham risk strata. Especially in diabetic patients with a risk score above 20%, multifactorial treatment could be effective in improving the FRS. [...]multifactorial interventions for CVD risk factors in the community are important to reduce the incidence of endpoint events in Chinese diabetic patients with hypertension or CVD. [...]we suggest the use of FRS score to stratify patients' CVD risk when analyzing the efficacy of management at regular intervals.

Extrusion-cooked instant rice was prepared by optimizing the formulation with emulsifiers, glycerol monostearate (GMS), soybean lecithin (LC), and sodiumstearoyl lactylate (SSL), and thickeners, gum Arabic (GA), sodium alginate (SA), and sticky rice (SR). The emulsifiers addition caused increase of degree of gelatinization (DG), and decrease of water soluble carbohydrate (WSC), α-amylase sensitivity, water soluble index (WAI) and adhesive for extrudates, while the thickeners addition increased extrudates DG, bulk density (BD), WSC, α-amylase sensitivity, WAI, hydration rate (HR) and adhesiveness. Based on the data generated by a single additive at various levels, optimum formulation was obtained employing orthogonal matrix system with combination of the selected additives for extrusion cooking. Extrudates were evaluated for optimum hydration time followed by drying to prepare the finished product. Texture profile analysis and sensory evaluation indicate that quality of the finished product is equivalent to that of the round shaped rice and superior to a commercial instant rice product. This study also demonstrates possibility of value-added and versatile instant rice product development using broken rice.

We use the time dependent variational matrix product state (tVMPS) approach to investigate the dynamical properties of the single impurity Anderson model (SIAM). Under the Jordan-Wigner transformation, the SIAM is reformulated into two spin-1/2 XY chains with local magnetic fields along the z-axis. The chains are connected by the longitudinal Ising coupling at the end points. The ground state of the model is searched variationally within the space spanned by the matrix product state (MPS). The temporal Green's functions are calculated both by the imaginary and real time evolutions, from which the spectral information can be extracted. The possibility of using the tVMPS approach as an impurity solver for the dynamical mean field theory is also addressed. Finite temperature density operator is obtained by the ancilla approach. The results are compared to those from the Lanczos and the Hirsch-Fye quantum Monte-Carlo methods.
