Here we report a 3-dimensional dye-sensitized solar cell (3D-DSSCs) and module simulating the fractal structure of the pine tree for capturing sunlight. Compared to traditional flat solar cells, this type of solar cell exhibits superiority of absorbing sunlight from all directions. The...

The hotel industry continues embracing loyalty/rewards programs as a major platform to nurture customer relationships as well as reap return business. The reality is that major hotels have been aggressively spending more but achieve less in defending existing customers. We address this void by...

An extended complex system is a large scale hierarchical system controlled by two or more teams of decision-makers. The teams may have different objective functions, and often can be in direct conflict with each other. Within each team, the decision-makers must cooperate for the collective...

Organizations employ various risk-mitigation strategies to cope with the uncertainty in marketing new products. In the motion picture industry, an important strategy is to cast star actors and actresses in movies. The ultimate box-office success, however, depends on multiple stakeholders...

This paper explores the empirical evidence of the link between residents’ low-carbon awareness and their behaviors in China. A questionnaire measuring seven dimensions (including low-carbon knowledge, low-carbon value, low-carbon attitude, private low-carbon behavior, public low-carbon...

A novel structure of dye-sensitized solar cell (DSSC) with integrated photoanode was first reported in this paper. Titanium threads and titanium sheet were first used in this novel structure in place of traditional glass substrate, thus reducing the series resistance of the substrates. An...

The water supply to Chinese cities is increasingly degrading from pollution due to watershed activities. Consequently, water source protection requires urgent action using optimal land-use management efforts. An inexact linear programming model for optimal land-use management of surface water...

Integrated watershed management is required to ensure the reasonable use of resources and reconcile interactions among natural and human systems. In the present study, an interval fuzzy multiobjective programming (IFMOP) method was used to solve an integrated watershed management problem. Based...

Community detection is one of the most important problems in complex networks. Many algorithms have been proposed in the last decade, and most of them focus on the non-overlapping community structures in the early days. Overlapping and hierarchical structures are another two important properties...
