Promotion of green housing is of utmost importance in the achievement of sustainability in the built environment. While the states often use legislation or offer subsidies to motivate developers to build green, market forces can lead to green housing provision without any state intervention if the market players are willing to pay extra for the green attributes of housing. This study aims to explore residents’ willingness to pay (WTP) and preferences for green housing attributes based on the findings from a structured questionnaire survey in Hong Kong. The housing attributes under investigation include the uses of green materials and construction methods (e.g. timber from sustainable sources), energy-efficient technologies (e.g. LED lighting) and water-saving devices (e.g. grey water recycling system). Results indicate that apart from moral or altruistic reasons, residents’ WTP was mainly motivated by economic incentives. Green housing attributes which can directly reduce residents’ utility bills corresponded to greater WTP. Besides, environmental attitude was found a strong determinant of the WTP. Policy implications of the research findings then follow.

We apply polyelectrolyte multilayer films by consecutive alternate adsorption of positively charged polyallylamine hydrochloride and negatively charged sodium polystyrene sulfonate to the surface of graphene field effect transistors. Oscillations in the Dirac voltage shift with alternating positive and negative layers clearly demonstrate the electrostatic gating effect in this simple model system. A simple electrostatic model accounts well for the sign and magnitude of the Dirac voltage shift. Using this system, we are able to create p-type or n-type graphene at will. This model serves as the basis for understanding the mechanism of charged polymer sensing using graphene devices, a potentially technologically important application of graphene in areas such as DNA sequencing, biomarker assays for cancer detection, and other protein sensing applications.

Over the past several decades, biologists have conducted numerous studies examining both general and specific functions of proteins. Generally, if similarities in either the structure or sequence of amino acids exist for two proteins, then a common biological function is expected. Protein function is determined primarily based on the structure rather than the sequence of amino acids. The algorithm for protein structure alignment is an essential tool for the research. The quality of the algorithm depends on the quality of the similarity measure that is used, and the similarity measure is an objective function used to determine the best alignment because of their individual strength and weakness However, none of existing similarity measures became golden standard They require excessive filtering to find a single alignment. In this paper, we introduce a new strategy that finds not a single alignment, but multiple alignments with different lengths. This method has obvious benefits of high quality alignment. However, this novel method leads to a new problem that the running time for this method is considerably longer than that for methods that find only a single alignment. To address this problem~ we propose algorithms that can locate a common region （CORE） of multiple alignment candidates, and can then extend the CORE into multiple alignments. Because the CORE can be defined from a final alignment, we introduce CORE＊ that is similar to CORE and propose an algorithm to identify the CORE＊. By adopting CORE＊ and dynamic programming, our proposed method produces multiple alignments of various lengths with higher accuracy than previous methods. In the experiments, the alignments identified by our algorithm are longer than those obtained by TM-align by 17% and 15.48%, on average, when the comparison is conducted at the level of super-family and fold, respectively.

In this expository article, the authors discuss the connection between the study of non-local operators on Euclidean space to the study of fractional GJMS operators in conformal geometry. The emphasis is on the study of a class of fourth order operators and their third order boundary operators. These third order operators are generalizations of the Dirichlet-to-Neumann operator.

Homogeneity or heterogeneity of cells is the most fundamental and important features of analyzing biological associations of genes and gene products. Recent bioinformatics technology requires an automated high-throughput analysis application that can handle massively produced data from next generation sequences and dramatically increased size of public proteomic/genomic databases. Although Gene ontology(GO) database has been newly spotlighted on its wide coverage of machine-readable terminologies, its complex DB schema and vast amount of applications utilizing GO without deep considerations of GO term relations dilute the actual power of GO-based analysis and resulted in misleading/under estimated outcomes. Meanwhile, our recent studies showed that BSM score, a new way of measuring functional similarity, clearly outperformed existing conventional methods. However, implementing BSM score that requires integrating multiple databases and calculating scoring matrix is not trivial and even difficult for bioinformatics experts; therefore, a web-based graphical user interface(GUI) tool, Gene Ontology Analysis Layer(GOAL: http://***/chenlab/goal) is introduced to provide user-friendly GO application powered by state of art functional similarity metric,BSM score.

We report the organization of polymer-dispersed liquid crystals (PDLCs) into ordered concentric rings over large areas by drying a drop of bound PDLC toluene solution (i.e., confined between a spherical lens and an indium tin oxide (ITO)-coated glass substrate; sphere-on-ITO geometry). The formation of regular ring-like deposits was a direct consequence of controlled"stick-slip"cycles of three-phase contact line during the course of solvent evaporation, which was effectively regulated through the use of the sphere-on-ITO geometry. This simple approach based on controlled evaporative organization may provide a new means of processing polymer/LC mixture to produce ordered surface patterns in one step, where microscopic LCs are dispersed within the polymer matrix.
