System for stabilizing cable phase delay utilizing a coaxial cable under pressure

Stabilizing the phase delay of signals passing through a pressurizable coaxial cable is disclosed. Signals from an appropriate source at a selected frequency, e.g., 100 MHz, are sent through the controlled cable from a first cable end to a second cable end which, electrically, is open or heavily mismatched at 100 MHz, thereby reflecting 100 MHz signals back to the first cable end. Thereat, the phase difference between the reflected-back signals and the signals from the source is detected by a phase detector. The output of the latter is used to control the flow of gas to or from the cable, thereby controlling the cable pressure, which in turn affects the cable phase delay

Stable group delay cable

It was found that group delay is function of pressure in air dielectric coaxial cable. For example, 600-ft air dielectric cable will change phase 10 deg at 150 MHz when air pressure in cable changes from zero to 20 psi

Are some forecasters' probability assessments of macro variables better than those of others?

We apply the bootstrap test of DíAgostino et al. (2012) to determine whether some forecasters are able to make superior probability assessments to others. In contrast to the findings of DíAgostino et al. (2012) for point predictions, there is more evidence that some individuals really are better than others. The testing procedure controls for the different economic conditions the forecasters may face, given that each individual responds to only a subset of the surveys. One possible explanation for the different findings for point predictions and histograms is explored: that newcomers may make less accurate histogram forecasts than experienced respondents given the greater complexity of the task

University Scholar Series: Craig B. Clements

Groundbreaking Research on Wildfire Weather On November 28, 2012 Craig B. Clements spoke in the University Scholar Series hosted by Provost Ellen Junn at the Dr. Martin Luther King, Jr. Library. Craig Clements is an associate professor in the Department of Meteorology and Climate Science who received a $900,000 National Science Foundation CAREER grant for his work in tracking atmospheric conditions in and around wildfires. His work will better help predict wildfire behavior and conditions that could lead to increased wildfire danger.https://scholarworks.sjsu.edu/uss/1016/thumbnail.jp

Deconstructing the stereotypes: building mutual respect

Through a combination of a detailed literature review and structure online survey, the study seeks to establish the extent of interdisciplinary attitudes within built environment students at Kingston University, whilst building a picture of not only the stereotypes held amongst and between disciplines, but also the fundamental root of such perceptions

Who is Being Saved Least by Family Planning Providers?A Study of Modern Contraceptive Use in Ghana,Tanzania and Zimbabwe

\ud This study was conducted to identify the poorest and other vulnerable sub-groups being served least by family planning providers. The study was set in three countries in sub-Saharan Africa, namely, Ghana, Tanzania and Zimbabwe. This region generally has a low but increasing uptake of modern contraceptive methods. As the use of family planning providers increases, there is a need to understand who is not being served and why. Logistic regression analyses of demographic and health survey data were conducted to identify the characteristics and geographical areas of women who are not using modern contraceptive methods. The results show some similarities among the countries in those using modern methods the least. However, a number of groups were country specific. Identifying the poorest women with the lowest use of modern methods is best done by assessing their household amenities or their partner's status rather than theirs.

GMOD for Evolutionary Biology

The Generic Model Organism Database (GMOD, "http://gmod.org":http://gmod.org) project provides interoperable, open source software tools for managing, visualizing and annotating biological data. GMOD is also a community of people addressing common challenges with biological data. Some well known software in GMOD includes GBrowse and JBrowse for genome browsing, Apollo for genome annotation, Chado for managing data, CMap for comparative map viewing, Galaxy for workflow creation and persistence, and BioMart for warehousing biological data.

This talk will focus on three areas of particular interest to iEvoBio participants. 
1) GBrowse_syn comparative genomics viewer
2) Natural Diversity Module of the Chado database schema
3) GMOD evolutionary biology hackathon 

The GBrowse_syn comparative genomics viewer displays synteny between a reference and any number of related species. It shows inversions, duplications, and indels, and can show synteny across non-contiguous regions. It is built on the widely used GBrowse genome viewer. The Natural Diversity Module is an extension to GMOD’s Chado database schema to enable Chado to support natural diversity, population genomics, individuals, breeding, phenotypes and geolocation information. This module is the first extension to Chado to be designed by the community, rather than at one institution. We will close by soliciting nominations and ideas for a GMOD Evolutionary Biology Hackathon. This hackathon will be held November 8-12, at NESCent, which is sponsoring the event. There will be an open call for participation in August.
