contemporary cities from many aspects have challenges with the phenomenon of injustice and in different areas suffer from the distribution of benefits, housing, and access to services. meanwhile, the spatial justice and related studies have raised in response to these issues as an emerging and interdisciplinary field. hence, justice has become a principal goal of urban planning in its instituti...

background: to investigate the relation between serum leptin levels and cerebral infarction (ci) by meta-analysis. materials and methods: scientific literature databases were searched for studies published in chinese and english. after retrieving relevant articles through database searches and screening using predefined selection criteria, high-quality studies related to our research topic were...

BACKGROUND Individual differences among breast tumours in patients is a significant challenge for the treatment of breast cancer. This study reports a strategy to assess these individual differences and the common regulatory mechanisms that may underlie breast tumourigenesis. MATERIALS AND METHODS The two-step strategy was based firstly on a full-scale proteomics analysis of individual cases,...

We are concerned with a core aspect of the processes of obtaining conceptual models. We view such processes as information gathering dialogues, in which strategies may be followed (possibly, imposed) in order to achieve certain modelling goals. Many goals and strategies for modelling can be distinguished, but the current discussion concerns meta-model driven strategies, aiming to fulfil modelli...

Local search is an integral part of many meta-heuristic strategies that solve single objective optimisation problems. Essentially, the meta-heuristic is responsible for generating a good starting point from which a greedy local search will find the local optimum. Indeed, the best known solutions to many hard problems (such as the travelling salesman problem) have been generated in this hybrid w...

The most effective scheme of truss optimization considers the combined effect of topology, shape and size (TSS); however, most available studies on truss optimization by meta-heuristics concentrated on one or two of the above aspects. The presence of diverse design variables and constraints in TSS optimization may account for such limited applicability of meta-heuristics to this field. In this ...

Meta-study is a method for analysing the content and process of knowledge production in body qualitative research. Conducting meta-study involves four steps: (1) meta-data-analysis which study empirical findings; (2) meta-method examines epistemological soundness rigour methods; (3) meta-theory structures, assumptions, principles underpinning primary research studies; (4) meta-synthesis brings ...

Objectives The therapeutic efficacy of cytoreductive surgery (CRS) plus hyperthermic intraperitoneal chemotherapy (HIPEC) for patients with peritoneal carcinomatosis (PC) from colorectal cancer (CRC) is still under debate. This meta-analysis and systematic review of published literature on this comprehensive strategy aims to evaluate its efficacy on CRC patients with PC.Methods A systemic revie...

Multiple imputation is a strategy for the analysis of incomplete data such that the impact of the missingness on the power and bias of estimates is mitigated. When data from multiple studies are collated, we can propose both within-study and multilevel imputation models to impute missing data on covariates. It is not clear how to choose between imputation models or how to combine imputation and...

We combine second order local regression meta-models with the Covariance Matrix Adaptation Evolution Strategy in order to enhance it’s efficiency in the optimization of computationally expensive problems. Computationally intensive direct numerical simulations of an anguilliform swimmer provide the testbed for the optimization. We propose two concepts to reduce the computational cost of the meta...
