Do bibliometricians cite differently from other scholars?
Authors: Case Donald O. , Miller Joseph B. 
Published: January 2011

AbstractWhy authors cite particular documents has been the subject of both speculation and empirical investigation for decades. This article provides a short history of attempts to understand citation motivations and reports a replication of earlier surveys measuring reasons for citations. Comparisons are made among various types of scholars. The present study identified six highly cited articles in the topic area of bibliometrics and surveyed all of the locatable authors who cited those works (n=112). It was thought that bibliometricians, given that this is their area of expertise, might have a heightened level of awareness of their own citation practices, and hence a different pattern of responses. Several reasons indicated by the 56% of the sample who identified themselves as bibliometricians differed in statistically significant ways from nonbibliometricians, and also from earlier samples of scholars in Communication and Psychology. By far the most common reason for citing a document is that it represents a genre. A factor analysis shows that 20 motivations, clustered in seven factors, can represent the most common motivations for citation. The implications of these findings are discussed in the light of recent debates about the role of social factors in citation. Alternative methods for investigating citation behavior are discussed.
Feedback predictive control for constrained fuzzy systems with Markovian jumps
Authors: Wen Jiwei , Liu Fei , Nguang Sing Kiong 
Published: January 2011

AbstractIn this paper, a feedback model predictive control method is presented to tackle control problems with constrained multivariables for uncertain discrete‐time nonlinear Markovian jump systems. An uncertain Markovian jump fuzzy system (MJFS) is obtained by employing the Takagi‐Sugeno (T‐S) fuzzy model to represent a discrete‐time nonlinear system with norm bounded uncertainties and Markovain jump parameters. To achieve more generality, the transition probabilities of the Markov chain are assumed to be partly unknown and partly accessible. The predictive formulation adopts an on‐line optimization paradigm that utilizes the closed‐loop state feedback controller and is solved using the standard semi‐definite programming (SDP). To reduce the on‐line computational burden, a mode independent control move is calculated at every sampling time based on a stochastic fuzzy Lyapunov function (FLF) and a parallel distributed compensation (PDC) scheme. The robust mean square stability, performance minimization and constraint satisfaction properties are guaranteed under the control move for all admissible uncertainties. A numerical example is given to show the efficiency of the developed approach.Copyright © 2011 John Wiley and Sons Asia Pte Ltd and Chinese Automatic Control Society
Information measures of Dirichlet distribution with applications
Authors: Ebrahimi Nader , Soofi Ehsan S. , Zhao Shaoqiong (Annie) 
Published: January 2011

AbstractWe explore properties of information measures of the Dirichlet family and related distributions. Representations of the information measures of the Dirichlet family in terms of the information measures of the gamma family reflect the characterization of Dirichlet distribution in terms of the ratios of independent gamma distributions to their sum. We present measures of information provided by a multinomial vector about the multinomial parameters under the Dirichlet prior and measures of information loss due to aggregation of Dirichlet components and the multinomial categories. New information characterizations of the bivariate Dirichlet distribution in terms of survival and hazard gradient constraints are given. The information analysis of contingency tables is briefly described. An example illustrates applications of Dirichlet prior for inferences about information measures of contingency tables and Kendall's tau for ordinal data. Results that compare solicitation of the mean and mode vectors for the Dirichlet model are given and are illustrated through an example from a study of business executives' environmental uncertainty in the aftermath of 9/11 terrorist attacks. The probability integral transformation is proposed for facilitating implementation of the maximum entropy Dirichlet process prior procedure for inference about the fit of continuous distributions to the data.

Transcription factors regulating the progression of monocot and dicot seed development
Authors: Agarwal Pinky , Kapoor Sanjay , Tyagi Akhilesh K. 
Published: January 2011

AbstractSeed development in this paper has been classified into the three landmark stages of cell division, organ initiation and maturation, based on morphological changes, and the available literature. The entire process proceeds at the behest of an interplay of various specific and general transcription factors (TFs). Monocots and dicots utilize overlapping, as well as distinct, TF networks during the process of seed development. The known TFs in rice and Arabidopsis have been chronologically categorized into the three stages. The main regulators of seed development contain B3 or HAP3 domains. These interact with bZIP and AP2 TFs. Other TFs that play an indispensable role during the process contain homeobox‐, NAC‐, MYB‐, or ARF‐domains. This paper is a comprehensive analysis of the TFs essential for seed development and their interactions. An understanding of this interplay will not only help unravel an integrated developmental process, but will also pave the way for biotechnological applications.
Molecular mechanisms of interspecies transmission and pathogenicity of influenza viruses: Lessons from the 2009 pandemic
Authors: Klenk Hans D. , Garten Wolfgang , Matrosovich Mikhail 
Published: January 2011

AbstractThe emergence of the 2009 H1N1 virus pandemic was unexpected, since it had been predicted that the next pandemic would be caused by subtype H5N1. We also had to learn that a pandemic does not necessarily require the introduction of a new virus subtype into the human population, but that it may result from antigenic shift within the same subtype. The new variant was derived from human and animal viruses by genetic reassortment in the pig, supporting the concept that this animal is the mixing vessel for the generation of new human influenza viruses. Although it is generally believed that the 2009 outbreak was mild, there have been severe cases particularly among the young and the middle‐aged. Pathogenicity and host range are determined to a large extent by the polymerase, the haemagglutinin and the NS1 protein of influenza A viruses. There is evidence that mutations of these proteins may change the pathogenicity of the new virus.
The use of a guide catheter extension system as an aid during transradial percutaneous coronary intervention of coronary artery bypass grafts
Authors: Farooq Vasim , Mamas Mamas A. , Fath‐Ordoubadi Farzin , Fraser Douglas G. 
Published: January 2011

AbstractAims: Prior coronary artery bypass graft (CABG) surgery is one of the main predictors of failure of transradial PCI. Frequently this is due to difficulty in graft cannulation and/or poor backup support. In addition to Proxis's™ embolic protection role, the Proxis™, Heartrail™, and GuideLiner™ guide catheter extension devices have all been shown to facilitate coronary intervention by increasing backup support and aiding stent delivery. We describe our institution's experiences using these devices to aid transradial graft intervention. Methods: Between October 2007 and March 2010, the utility and safety of these devices were assessed in consecutive transradial graft intervention procedures. Proxis™ cases used for proximal protection alone were excluded. Deep intubation was defined as an intubation depth of ≥2cm. Results: Guide catheter extensions were used in 33 of 41 transradial graft interventions identified. Proxis™ was used for proximal protection alone in 3 cases, leaving 30 cases as the study group (Heartrail™ n = 18, GuideLiner™ n = 3, Proxis™ n = 9). In all study cases procedural success with final TIMI‐3 flow was achieved. Guide catheter extensions were used to aid during graft cannulation (n = 11), to improve backup support via deep intubation (n = 26) and as an adjunctive aspiration device (n = 11). Filter‐based distal embolic protection devices were used in 11/21 Heartrail™ and GuideLiner™ cases. Deep intubation depths ranged from 30 to 138 mm (mean 61 mm) with no complications related to deep intubation seen. Conclusions: The use of guide catheter extension systems facilitated transradial graft intervention via several mechanisms including aid to graft cannulation, increasing backup support, and as an adjunctive aspiration device. © 2011 Wiley Periodicals, Inc.

AbstractDownstream processing for isomaltose by purification on BEA‐zeolites was investigated. The important process steps are washing procedure, desorption, and reactivation of the adsorbent. Purity and yield were influenced by the enzyme system. Desorption kinetics was determined at 50 ° and 70 °C. Complete desorption was performed in a three stage cross‐flow‐sequence. The reactivation of BEA‐zeolite is feasible with additional effort for Na+‐cation exchange.
Adsorption from Molecular to Process Scale – Where Intensification Meets Integration

Published: January 2011

AbstractBiopharmaceutical processes are complex in almost every aspect, they are not well understood, and so far they have not seen much integration, far less intensification. Adsorption plays a key role for handling, purifying, and processing of such complex systems. The current modular approach to a bioprocess chain needs integration and also more consideration of sustainability aspects. Integrated processes are a prerequisite for the supply of patients all over the world with high quality, innovative, and affordable therapeutics, also allowing stratified medicine approaches.
