Using a very small sample of 8 datasets it was recently shown by De Visscher (2011) that the g-index is very close to the square root of the total number of citations. It was argued that there is no bibliometrically meaningful difference. Using another somewhat larger empirical sample of 26 datasets I show that the difference may be larger and I argue in favor of the g-index. 1. Introduction Th...

Nitric oxide (NO) plays a critical role in the regulation of a wide variety of physiological processes. It is a potent inhibitor of platelet adhesion and aggregation, inhibits bacterial adhesion and proliferation, is implicated in mediating the inflammatory response toward implanted devices, plays a role in tumor growth and proliferation, and is a neurotransmitter. Herein, we describe the synth...

This paper shows the first application of in situ manipulation of discontinuous fibrous structure mid-print, within a 3D printed polymeric composite architecture. Currently, rapid prototyping methods (fused filament fabrication, stereolithography) are gaining increasing popularity within the engineering commnity to build structural components. Unfortunately, the full potential of these componen...

In recent years, robots that coexist with human are under active researches. Such robots need high safety, backdriveability, large generative force, high speed response, good controllability, and so on. We have put emphasis on the backdriveability and created a novel prototype linear actuator with an ER (Electro-Rheological) gel, a new functional material. It is an all-purpose actuator satisfyi...

Compared to conventional particle accelerators, plasmas can sustain accelerating fields that are thousands of times higher. To exploit this ability, massively parallel SciDAC particle simulations provide physical insight into the development of next-generation accelerators that use laser-driven plasma waves. These plasmabased accelerators offer a path to more compact, ultra-fast particle and ra...

BACKGROUND Current methods of measuring the quality of journals assume that citations of articles within journals are normally distributed. Furthermore using journal impact factors to measure the quality of individual articles is flawed if citations are not uniformly spread between articles. The aim of this study was to assess the distribution of citations to articles and use the level of non-c...

OBJECTIVE Determine drivers of academic productivity within U.S. departments of surgery. METHODS Eighty academic metrics for 3,850 faculty at the top 50 NIH-funded university- and 5 outstanding hospital-based surgical departments were collected using websites, Scopus, and NIH RePORTER. RESULTS Mean faculty size was 76. Overall, there were 35.3% assistant, 27.8% associate, and 36.9% full pro...

BACKGROUND Bibliometric studies are increasingly being used for research assessments. Bibliometric indicators involve the application of statistical methods to scientific publications to obtain the bibliographics for each journal. The main objective of this study was to conduct a bibliometric evaluation of Human & Experimental Toxicology retrieved from the Scopus database. METHODS This study ...

Today, in addition to citations and with the expansion of social Background: media, the use of altmetrics has gained attention as a tool necessary for evaluating the effects of scientific publications. The present study intended to monitor Iranian pediatrics articles, as one of the leading areas of scientific publications in Iran, between the years 2010-2016 using altmetrics and citation-metric...

There is a growing literature that aims at assessing the private value of knowledge assets and patents. It has been shown that patents and their quality as measured by citations received by future patents contribute significantly to the market value of firms beyond their R&D stocks. This paper goes one step further and distinguishes between different types of forward citations patents can recei...
