Introducing buckling pattern into straight-walled lattice structure, anovel inspired meta-structure (BILM) was designed and fabricated using polylactic acid (PLA) by three-dimensional (3D) printing technology. The square structure with positive Poisson’s ratio (PPR) is transformed negative (NPR) induction. Curved struts decrease the maximum strain, prohibit strut fracture, increase contact indu...

Several alternative methods are available when testing for moderators in mixed-effects meta-regression models. A simulation study was carried out to compare different methods in terms of their Type I error and statistical power rates. We included the standard (Wald-type) test, the method proposed by Knapp and Hartung (2003) in 2 different versions, the Huber-White method, the likelihood ratio t...

background: gastric cancer is the second most common cause of death from cancer. as conflicting studies have recently been published, we aimed to evaluate the magnitude of the epidemiological evidence for an association between alcohol consumption and gastric cancer. methods: this study is a meta-analysis of case-control studies which have been performed during 1989 to 2007. we systematically r...

As nanofabrication technology progresses, the emerging metasurface has offered unique opportunities for holography, such as an increased data capacity and the realization of polarization-sensitive functionality. Multicolor three-dimensional (3D) meta-hologram imaging is one of the most pursued applications for meta-hologram not yet realized. How to reduce the cross-talk among different colors i...

BACKGROUND Many randomised trials have count outcomes, such as the number of falls or the number of asthma exacerbations. These outcomes have been treated as counts, continuous outcomes or dichotomised and analysed using a variety of analytical methods. This study examines whether different methods of analysis yield estimates of intervention effect that are similar enough to be reasonably poole...

Rapid digitalisation has resulted in a literature about technology acceptance that is ever increasing size, naturally creating debates the developments field and their implications. Given size of range factors, theories applications considered, this article reviewed relevant using meta-analytical approach. The objective review was twofold: (a) to provide comprehensive analysis factors contribut...

The International Workshop on Meta-Models and Schemas for Reverse Engineering aims at utilizing meta-technology for the development of reverse engineering toolsets. The workshop objective is to determine and specify areas in reverse engineering which will benefit from meta-technology and to discover and discuss meta-technologies which will provide significant additional support for developing a...

OBJECTIVE To determine the effectiveness of technology-based distance interventions for promoting physical activity, using systematic review and meta-analysis. METHODS A literature search of studies published between 2000 and 2015 was conducted in the following databases: CENTRAL, EMBASE, Ovid MEDLINE, CINAHL, PsycINFO, OTseeker, WOS and PEDro. Studies were selected according to the PICOS fra...

In this paper, we propose an efficient approach to design optimization of analog circuits that is based on the reinforcement learning method. In this work, Multi-Objective Learning Automata (MOLA) is used to design a two-stage CMOS operational amplifier (op-amp) in 0.25μm technology. The aim is optimizing power consumption and area so as to achieve minimum Total Optimality Index (TOI), as a new...

information technology has been considered the greatest innovation of the new era because it has a lot of fruitful social economic and scientific impacts. e-marketing joins creative and technical aspects of the internet, including: design, development, advertising and sales. this research aims to design an e-marketing framework by using meta-synthesis method. in order to design and explain a co...
