UK Professors Give a Positive View of LGBTQ Identities

What was expected to be a small project attracted such an inspiring amount of positive feedback from the community, that the authors wanted to share the stories with a broad audience. Using personal narratives from their research, their book focuses on how LGBTQ-identified individuals can cultivate a sense of well-being and a personal identity that allows them to flourish in all areas of life.

Some Self-Assembly Required: Polymeric Magneto-Nano-Mechanical Systems

Fluid mechanical forces can be used to naturally induce polymeric

liquids to self-assemble into suspended fibers, membranes and

air-bridges that have nanoscale features and aspect ratios exceeding

10,000:1. The fabrication process is quite robust, enabling defect-free

arrays of identical structures to be produced with even crude hand

application. Nanofiber air-bridges have been produced in seconds with

numerous types of organic polymers, nanomaterial-polymer composites, and

biopolymers—including with fibrin and DNA.


Most recently we have assembled an ultraflexible air-bridge in the form

of a micron-scale bead on a 50 to 200 nanometer diameter string. The

relatively large bead enables both simple observation and

nanomanipulation of the structure under a light microscope. Force

detection limits of under a piconewton are estimated, making visual

sensing under a light microscope a possible alternative to traditional

atomic force microscopy and laser trapping for detection of biomolecular

forces. This talk will present the self-assembly method, measurements of

resulting magneto-mechanical properties of the beaded fibers, and new

ideas for using the magnetic nanorods to further control and modify the

process of self-assembly.

Computational Sciences Seminar Mark Fahey

“Scientific Computing in Practice at NSF, DoE, and DoD HPC Centers”

 

Mark Fahey

University of Tennessee/ORNL

(Refreshments at 3:00 p.m.)

 

ABSTRACT:  I will talk about my experiences in the area of Scientific Computing since finishing my PhD work in 1998.  I have worked at DoD, DoE, and NSF supercomputing centers over the last 13 years.  In this relatively short time, there have been significant changes in the area of supercomputing, and yet also some things have changed very little.  I will describe a few examples of the types of computational science projects that I have been a part of.  To conclude, a summary of what helped prepare me for this career path will be presented as well as other highly desirable traits in this field.
