After publishing 21,000 pages of high-impact research articles in 2007, PNAS continues full steam ahead. Although other journals have given rise to incrementally more specialized research and review journals, we have kept the mission of PNAS to serve science as the official journal of the National Academy of Sciences, with its associated breadth and depth, close to heart. With a competitive impact factor of 9.6 and a 19% acceptance rate for papers submitted directly, PNAS remains one of the most prestigious and highly cited multidisciplinary research journals.

Never content to rest on our laurels, we are continually searching for ways to improve and advance PNAS with new features and services. Survey Says Results from a survey of PNAS authors (347 respondents) indicate that 87% are satisfied with the online manuscript submission process, 86% are satisfied with the peer review process, 86% are satisfied with the copyediting, and 91% are satisfied with the overall production process. We are reviewing the comments carefully to see how we can bring author satisfaction closer to 100%. Two major areas that we have begun to improve are typesetting math, equations, and special characters (67% of respondents are satisfied with this function) and the character count and manuscript-sizing process (62% are satisfied). We have a new workflow for math-heavy papers that enables us to edit and compose the author's originally supplied TeX file without having to rekey text or equations.

Here are the topics discussed in each lesson: adjectives, adverbs, plural, prepositions, feminine, numbers, negation, pronouns, questions, determiners, nouns, verbs, present tense, past tense, future tense, imperative, and the comparative. Each course contains an extra topic about vocabulary. Tenses in english grammar worksheets. Going through each lesson should take about 30 min. Make sure to take advantage of that as well.

We are also developing an easy-to-use manuscript submission template, which should be available this summer, to provide a simpler and more accurate estimate of article length. Get Featured To ease the page-limit burden and to attract exceptional articles, we have launched Feature Articles (), in-depth research reports with exceptional breadth. Feature Article submissions are handled personally by the Editor-in-Chief or an Associate Editor and receive our usual prompt, rigorous, and fair peer review. Given the importance we place on such articles, the six-page limit is waived, and publicity includes a Commentary and, as appropriate, a press release.

PNAS collaborates with FundRef to use a standard taxonomy of funder names. Dedications are rarely allowed. References must be in PNAS style. For references to in-press articles, please confirm with the cited journal that the article is in press and include a DOI number and online publication date. Document Templates. Authors are encouraged to use the Article template or Communication template for preparing manuscripts, but it is not required. Authors who choose not to employ a template are asked to paste their graphics within the text close to the place of first mention, as this will produce documents that are easier to review.

We encourage you to submit your next such paper for consideration. Fewer Clicks Another way to ease the page-limit burden is online-only supporting information (SI).

More than 72% of our research articles contain SI, which includes nearly 14,000 files each year of images, datasets, expanded materials and methods, movies, etc. Beginning in February, we will prepare an integrated PDF that contains all SI items so that 15 figures no longer require 15 clicks or more to be viewed. By summer, we hope to ensure that referees receive a similar integrated PDF for SI so they can also access the files with fewer clicks. At PNAS, we copyedit, format, peer review, and permanently archive all SI.

Therefore, between review and publication, the copy editors must access the original files to make edits and to size figures. Honest Images Including SI, PNAS publishes 24,000 figures each year. Our policies on digital image manipulation are stated in our Information for Authors: No specific feature within an image may be enhanced, obscured, moved, removed, or introduced. The grouping or consolidation of images from multiple sources must be made explicit by the arrangement of the figure and in the text of the figure legend. Adjustments of brightness, contrast, or color balance are acceptable if they are applied to the whole image and as long as they do not obscure, eliminate, or misrepresent any information present in the original, including backgrounds. To enforce this policy we have begun screening our images with a software program that can detect traces of manipulation such as cloning and pasting, adjustments to contrast that may obscure data, and areas with inconsistent background pixelation. We expect that the majority of findings of inconsistencies will be the result of an author cleaning up an image rather than a deliberate attempt to obscure or misrepresent data.
