We investigate the adverse selection problem where a principal delegates multiple tasks to an agent. We characterize the virtually implementable social choice functions by using the linking mechanism proposed by Jackson and Sonnenschein (2007) that restricts the message spaces. The principal does not require any incentive wage schemes and can therefore avoid any information rent and welfare los...

Abstract Mesoporous silica was prepared using sodium silicate as a precursor and Cetyl Trimethylammonium Bromide (CTAB) templating agent. The adsorption ability of enhanced by DMA (dimethylamine) modifier glycidoxypropyltrimethoxysilane (GPTMS) linking compound. process carried out incorporating the chloride solution into DMA-modified mesoporous silica, followed desorption flowing acid solution...

Visualisations have previously combined linking and brushing operations successfully. However, none to our knowledge have combined linking and focussing techniques. We describe the motivation behind developing such a technique, and show how our visualisation takes advantage of inherent links in a set of multiple overlapping hierarchies to build a mechanism that can produce linked focus + contex...

This paper reports a method for preparing artificial leather with high comfort and useful mechanical property. Blending thermoplastic polyurethane elastomer (TPU), Toluene diisocyanate (TDI) prepolymer 4,4-Methylene bis(2-chloroaniline) (MOCA), nanofiber was obtained by using online reactive electrospinning technology heat cross-linking. Compared the commercial PU leather, tensile strength of f...

background: corneal collagen cross-linking with riboflavin, also known as collagen cross-linking (cxl), involves the application of riboflavin solution to the eye that is activated by illumination with ultraviolet a (uva) light. we survey here the topographic corneal changes one year after cxl in patients with corneal keratoconus. materials and methods: this prospective randomized clinical tria...

PURPOSE The purpose of our study was to investigate the cellular accumulation, DNA cross-linking ability, and cellular toxicity of RH1 (2,5-diaziridinyl-3-[hydroxymethyl[-6-methyl-1,4-benzoquinone), a novel DNA alkylating agent currently in clinical trials. In addition, the in vivo efficacy of RH1 formulated in different vehicles was also compared. EXPERIMENTAL DESIGN RH1 is activated by the ...

An agent-based model of food web evolution is presented and contrasted with a particular system dynamics model. Both models examine the effects of speciation and species invasion of food webs, but the agent-based approach focuses on the interactions between individuals in the food web, whereas the system dynamics approach focuses on the overall system dynamics. The system dynamics model is an a...
