“In essence, he said, there were really two apps –- one for pedestrians and one for drivers. In pedestrian mode, the user needs to hold down the shutter button, which will produce a continuous series of photographs until the incident is over. The user chooses one of four offense categories (traffic violation, road bullying, accident, road hazard) and the images are uploaded onto Nirsham’s servers, where they are analyzed for authenticity (to prevent the possibility of an individual uploading a doctored image to “get back” at someone they don’t like, said Goldman). The images are then displayed on the Nirsham site, where other members of the community can analyze them and decide whether or not a traffic offense was committed.”

Cellular…Mechanisms of Physical Activity-Induced Health Benefits http://www.cell.com/cell-metabolism/abstract/S1550-4131(15)00223-5 Mitochondria important to “#exercise responsome”

… augmenting overall mitochondrial density and oxidative
phosphorylation capacity by as much as 2-fold (Hood et al., 2011). Moreover, PA affects mito-chondrial quality as well as quantity, and recent studies suggest that the functional properties of these organelles are much more heterogeneous and dynamic in nature than previously appreci-ated (Jacobs and Lundby, 2013). Interestingly, PA-induced mito-chondrial biogenesis also occurs in tissues other than skeletal muscle, including brain (E et al., 2013; Steiner et al., 2011), liver (Boveris and Navarro, 2008; E et al., 2013; Navarro et al., 2004), adipose tissue (Laye et al., 2009; Sutherland et al., 2009), and kidney (Navarro et al., 2004), providing evidence that exercise also increases metabolic demand in these tissues and/or stimu-lates inter-organ crosstalk.
….
The rate-limiting impediment to discovery of molecular trans-ducers and their function is not the ‘‘omic” core technology, but the bioinformatics to extract the most useful signals and generate the most appropriate biological interpretation, including those associated with exercise adaptation. Robust computational and bioinformatics analytical tools allowing inte-gration of large datasets from a multiplicity of ‘‘omics” platforms with in vivo exercise physiology assays and measurements would contribute greatly to our understanding of the response to acute bouts of exercise and long-term adaptation to regular exercise exposure.
….
this regard, the development of detailed molecular profiles in cells and tissues in response to acute and chronic exposures to exercise (‘‘the exercise responsomes”) would provide the benchmark against which all other exercise-related conditions, including aging, sex differences, disease states, etc., could be compared for commonality and specificity.

Resources are needed not only to fund new trainees, but also to restructure current programs in a manner that combines studies in integrative physiology and bioenergetics with training in basic biochemistry, cellular and molecular biology, and bioinformatics. Additional resources are needed to establish mechanisms for assembling and supporting interdisciplinary teams that are able to catalyze and sustain ex-ercise research. The field would likewise benefit from a program to support a multi-site consortium of exercise scientists with complimentary expertise and resources that together are well positioned to tackle the large, challenging problems relevant to the overarching mission.

Are Polls Ruining Democracy?

QT:{{”
“If public-opinion polling is the child of a strained marriage between the press and the academy, data science is the child of a rocky marriage between the academy and Silicon Valley. The term “data science” was coined in 1960, one year after the Democratic National Committee hired Simulmatics Corporation, a company founded by Ithiel de Sola Pool, a political scientist from M.I.T., to provide strategic analysis in advance of the upcoming Presidential election. Pool and his team collected punch cards from pollsters who had archived more than sixty polls from the elections of 1952, 1954, 1956, 1958, and 1960, representing more than a hundred thousand interviews, and fed them into a UNIVAC. They then sorted voters into four hundred and eighty possible types (for example, “Eastern, metropolitan,
lower-income, white, Catholic, female Democrat”) and sorted issues into fifty-two clusters (for example, foreign aid). Simulmatics’ first task, completed just before the Democratic National Convention, was a study of “the Negro vote in the North.” Its report, which is thought to have influenced the civil-rights paragraphs added to the Party’s platform, concluded that between 1954 and 1956 “a small but
significant shift to the Republicans occurred among Northern Negroes, which cost the Democrats about 1 per cent of the total votes in 8 key states.” After the nominating convention, the D.N.C. commissioned Simulmatics to prepare three more reports, including one that involved running simulations about different ways in which Kennedy might discuss his Catholicism.”

“McDonald’s is a business. Lyfe Kitchen is an enlightened business. Sweetgreen, which was started in 2007 by three Georgetown graduates, aims to be a movement, selling a set of values in addition to its food. There are currently thirty-three Sweetgreen restaurants, and there are plans for many more. In nearly every city where the company has restaurants, it sponsors a program to educate fourth- and fifth-grade students about the basics of nutrition and the value of relying on seasonal produce. So far, Sweetgreen in Schools has reached four thousand students, most of whom come from lower-income families.” “}}

SF424 (R&R) Application and Electronic Submission Information for NIH

November 10, 2015

QT:{{”

11. Descriptive Title of Applicant’s Project

Enter a brief descriptive title of the project. This field is required.

A “new” application must have a different title from any other PHS project with the same PD/PI. A “resubmission” or “renewal” application should normally have the same title as the previous grant or application. If the specific aims of the project have significantly changed, choose a new title.

A “revision” application must have the same title as the currently funded grant.

NIH and other PHS agencies limit title character length to 81 characters, including the spaces between words and punctuation. Titles in excess of 81 characters will be truncated. Be sure to only use standard characters in the descriptive title: A through Z, a through z, 0 through 9, space ( ), and underscore (_).

QT:{{”
Font

Prepare the application using Arial, Helvetica, Palatino Linotype, or Georgia typeface in black font color. After text attachments are converted to PDF, font size in each final PDF document must be at least 11 points (or larger). (A Symbol font may be used to insert Greek letters or special characters; the font size requirement still applies.) Since some PDF converters may reduce font sizes, it is important to confirm that type density in each final PDF document, including both characters and spaces, is no more than 15
characters+spaces per linear inch and no more than six lines per vertical inch.

Note: 72 points/inch so 6 lines/inch at 11pt type translates into a line spacing of 11 pts + 1pt per line.

QT:{{”
Paper Size and Page Margins

Final PDF documents should be formatted to be no larger than standard paper size (8 ½” x 11). The final PDF document should have at least one-half inch margins (top, bottom, left, and right) for all pages. No information should appear in the margins, including the PI’s name and page numbers.

….
Figures, Graphs, Diagrams, Charts, Tables, Figure Legends, and Footnotes You may use a smaller type size but it must be in a black font color, readily legible, and follow the font typeface requirement. Color can be used in figures; however, all text must be in a black font color, clear and legible.

Sending Your Secrets Safely with Chaos | Logical Tightrope

November 1, 2015

QT:{{”

Cuomo’s method relies on this synchronized chaos, a somewhat mysterious discovery summarized in a 1990 paper [2] by Louis Pecora and Thomas Carroll at The Naval Research Laboratory. The phenomenon occurs in some situations when part of the outputof one chaotic system is used as an input for a twin chaotic system. If the two systems are properly synchronized, then the second system will mimic the behavior of the first with uncanny fidelity.

Just like Pecora, Carroll, Cuomo, and Oppenheim have done, we’ll look at synchronization in the chaotic Lorenz system (look at my post Edward Lorenz’s Strange Attraction for a Deeper Dive into the Lorenz system). The system comes from Edward Lorenz’s simplification of an atmospheric convection model, and its intriguing chaotic behavior has been studied for decades. It is defined by the following system of nonlinear differential equations:

Science Quotes

October 25, 2015

QT:{{”
But are we sure of our observational facts? Scientific men are rather fond of saying pontifically that one ought to be quite sure of one’s observational facts before embarking on theory. Fortunately those who give this advice do not practice what they preach. Observation and theory get on best when they are mixed together, both helping one another in the pursuit of truth. It is a good rule not to put overmuch confidence in a theory until it has been confirmed by observation. I hope I shall not shock the experimental physicists too much if I add that it is also a good rule not to put overmuch confidence in the observational results that are put forward until they have been confirmed by theory.Sir Arthur Stanley Eddington (1882-1944) English astronomer and physicist.

Millennium Bridge, London – Wikipedia, the free encyclopedia

October 25, 2015

QT:{{”

The bridge’s movements were caused by a ‘positive feedback’
phenomenon, known as synchronous lateral excitation. The natural sway motion of people walking caused small sideways oscillations in the bridge, which in turn caused people on the bridge to sway in step, increasing the amplitude of the bridge oscillations and continually reinforcing the effect.[6] On the day of opening, the bridge was crossed by 90,000 people, with up to 2,000 on the bridge at any one time.

Resonant vibrational modes due to vertical loads (such as trains, traffic, pedestrians) and wind loads are well understood in bridge design. In the case of the Millennium Bridge, because the lateral motion caused the pedestrians loading the bridge to directly participate with the bridge, the vibrational modes had not been anticipated by the designers. The crucial point is that when the bridge lurches to one side, the pedestrians must adjust to keep from falling over, and they all do this at exactly the same time. Hence, the situation is similar to soldiers marching in lockstep, but horizontal instead of vertical.

The lateral vibration problems of the Millennium Bridge are very unusual, but not entirely unique.[7] Any bridge with lateral frequency modes of less than 1.3 Hz, and sufficiently low mass, could witness the same phenomenon with sufficient pedestrian loading. The greater the number of people, the greater the amplitude of the vibrations. For example, Albert Bridge in London has a sign dating from 1873 warning marching ranks of soldiers to break step while crossing.[8] Other bridges which have seen similar problems are:
