以陕西省为例实证分析了规模报酬和行业结合视角下的农村信贷资金配置效率。结果表明,总体配置效率不够理想,但在逐年提升,且农业生产规模报酬递增。分析发现,技术进步和政策行业导向在生产中极其重要,影响着村镇不同行业的发展走势;经济环境变化对资金配置效率有很大影响,金融危机背景下,资金回流到农村的比例上升,资金配置效率略有提高,也相应促进了农村经济的发展。

Aim: The objectives of this study are to determine the epidemiology of biopsy-proven glomerular disease (GD) in Central Queensland and the effect of a severe cyclone on its incidence and clinical phenotype. Background: Central Queensland (CQ) has a relatively high incidence of kidney disease. Since its biopsy service commenced in 2005, there have been no data on biopsy-proven GD. It has been suggested that GD incidence changes around times of natural disasters. In February 2015, the CQ region was affected by a category 5 Cyclone Marcia. This provides an opportunity to explore possible environmental triggers of GD. Methods: This was a single-centre retrospective observational study on biopsy-proven kidney disease in CQ. All kidney biopsies performed between January 2005 and December 2019 were included. Patients with biopsy-proven GD during 3 years before and after Cyclone Marcia (from 2012 to 2018) were analysed. Results: 170 native kidney biopsies occurred during the 15 years. The number of annual biopsies steadily increased from 7 to 16. The most common biopsy-proven kidney disease was IgA Nephropathy (27%) followed by diabetic nephropathy (20%). GD comprised 64% of biopsies. Unlike other GD, the incidence of ANCA-associated vasculitis (AAV) significantly increased after cyclone (one pre- and eight post-cyclone, P value = 0.039). The majority of AAV cases occurred in the first year after the cyclone. Conclusion: Kidney biopsies in CQ provide important epidemiological data on biopsy-proven kidney disease. Cyclones have a possible effect on the incidence and clinical phenotype of ANCA associated vasculitis.

Herein,we report on surface plasmon(SP)-sensitive semitransparent inverted polymer photovoltaic(PV)devices that are based on multilayered material systems consisting of poly(3-hexylthiophene):fullerene-derivative bulk-heterojunction PV layers and thin gold or silver *** demonstrate that these PV devices allow the simultaneous generation of both electrical power and SPs on their anodes for photoexcitation just above the optical absorption edge of the PV layers,resulting not only in attenuated total reflection,but also in attenuated photocurrent generation(APG)under the SP resonance(SPR)***,we also confirm that the biomolecular interaction of biotin–streptavidin on the PV devices can be precisely detected via apparent SPR angle shifts in the APG spectra,even without the need for complex attenuated total reflection *** highlight our view that APG measurements made using these PV devices show great potential for the development of future generations of compact and highly sensitive SPR-based optical sensors.

为了改善空间框架结构的几何非线性分析,根据总势能驻值原理推导了一个三维梁单元,用增量切线刚度矩阵代替传统的增量割线刚度矩阵.新的切线刚度矩阵除了常用的线性刚度和几何刚度矩阵外,还包含2个变形刚度矩阵,这2个矩阵是由每个增量步中轴力和弯距的变化引起的,是单元变形的函数,包含轴向、横向和扭转变形的耦合项.考虑空间转动和弯距的特征,增加一个修正矩阵,使提出的单元通过刚体测试,达到良好的收敛性能.实例显示使用较少的单元模拟构件仍可有效、准确地得到空间框架的轴向扭转和弯扭屈曲的非线性性能.

This paper proposed a new normalized transform domain conjugate gradient algorithm (NT-CGA), which applies the data independent normalized orthogonal transform technique to approximately whiten the input signal and utilises the modified conjugate gradient method to perform sample-by-sample updating of the filter weights more efficiently. Simulation results illustrated that the proposed algorithm has the ability to provide a fast convergence speed and lower steady-error compared to that of traditional least mean square algorithm (LMSA), normalized transform domain least mean square algorithm (NT- LMSA), Quasi-Newton least mean square algorithm (Q-LMSA) and time domain conjugate gradient algorithm (TD-CGA) when the input signal is heavily coloured.
