Objective: Whole-cell (WC) modeling is a promising tool for biological research, bioengineering, and medicine. However, substantial work remains to create accurate comprehensive models of complex cells. Methods: We organized the 2015 Whole-Cell Modeling Summer School to teach WC modeling and evaluate the need for new WC modeling standards and software by recoding a recently published WC model in...
It is critical to estimate the biomass for assessing crop growth and predicting yield in crop. The hyperspectral techniques provide a powerful technique for monitoring crop biomass. The previous studies about using hyperspectral data to study crop mainly focused on models based on the full spectra or the manually selected spectra. The stability and prediction ability of full spectra models may be...
The PROSPECT radiative transfer model was widely used to estimate leaf biochemical parameters, such as chlorophyll, leaf mass per area (LMA) and equivalent water thickness (EWT). Many studies have reported that LMA is the most difficult to retrieve from PROSPECT primarily because the dry matter absorption features on the reflectance spectra of fresh leaves are largely masked by stronger water absorption...
A cross-platform three-dimensional (3D) system, Acu3D, was developed to visualize human meridians and acupoints. Firstly, a 3D model of human body with meridians and acupoints was built as the basic data for Acu3D. The existing relevant standards and clinical knowledge were collected and organized to construct a knowledge-base which was integrated into the system. Then, Acu3D was realized leveraged...
Taking the factor of customer switching into count, we analyze duopoly models in which both start-ups and established firms consider the competitive investment in R&D when they enter the new market. Firms make a decision on investment will influence the customer switching. The firms with investment may attract new customers from other firms which does not invest and then maintain more market share...
This paper describes how to construct the whole body movements model of Japanese Radio Calisthenics, that is able to calculate the joint positions of a body from the less parameters. In order to get the actual data for building the movement model, we did experiments using the optical motion capture system in a three dimensional space. From the data, we presented equations that are able to estimate...
The study on the agriculture model component information resources sharing mode is the basis for the retrieval and management of the agriculture model components in the distributed environment. This study proposed a new approach to use topic map matching and merging to generate the global model documents. First of all, it unified described the attributes, associations and file descriptive information...
Soil moisture is one of the major limiting factors that determine vegetation restoration in the semi-arid Loess Plateau. A grassland of 8.3 ha. above the gully line of valleys, was selected as a sampling field to analyze the spatial variation of soil moisture. Soil moisture in topsoil (0-20cm) and subsoil (40-60cm) at 107 sampling points were measured using oven-drying methods in the end of dry season...
The emergence of Long Tail in electronic markets illuminates that niche and obscure products which previously sold very little can make up a significant share of total sales. We build a circle city model with horizontal product differentiation to describe the electronic market involving niche products and a featured product. With the model, we analyze the competition between niche products and a featured...
In this paper, the necessity of ranking of the enterprise's informatization capacity maturity is researched on the basis of EICMM (Enterprise Informatization Capacity Maturity Model). Based on the EICMM, we adopt the proper method (Cluster Analytical Method) for the empirical research, commence from the evaluated index system, design the questionnaires and collect the related data of informatization,...
The study on the crop growth model parallel algorithm is help to improve the computing efficiency of models in the low-cost PC cluster environment. According to the positive feedback characteristic of the crop development simulation model, this study used the partitioning and pipelining technology, and raised the two parallel algorithms, which are the single-node parallel job scheduling algorithm...
The development of industry informationization and electronic commerce (e-commerce) promote the emergence of electronic market (e-market). One called electronic exchange (e-exchange) is a typical business model. It requires a higher security level for the business operating system. This paper systematically studies the e-exchange security problems from the view of e-commerce security, analyzes the...
Regression is an important prediction method to establish models between variables. The primitive regression algorithms ignore the sample weights, and consider all samples play an equal role in regression. But this kind of algorithms often loses efficacy when dealing with outliers, since outliers disturb the regression models greatly. For traditional switching regression, sample membership varies...
B2B electronic marketplaces have been increasingly transforming the way that organizations conduct trading activities, few studies have systematically examined factors that influence organizations' adoption of such innovative business channels. Drawn on the transaction cost theory and the relational exchange theory, this paper proposes a unified model of e- marketplace adoption by integrating transactional...
