    The world of celebrity-branded headphones just became a little bit larger...and a whole lot faster. SOUL Electronics and Jamaican sprinter/World's fastest man, Usain Bolt have entered in to a branding agreement. Under the agreement Bolt will represent the SOUL brand in various events and marketing campaigns throughout the year and he will also partner with SOUL to bring out his own special edition headphones. SOUL is most notably known for their SOUL by Ludacris headphone series, which features the rapper, Ludacris. The headphones are expected to debut this summer...just in time for the…

  • Noninvasive high resolution mechanical strain maps of the spine intervertebral disc using nonrigid registration of magnetic resonance images

    David A. Reiter, Fadi A. Fathallah, Rida T. Farouki, Jeffery H. Walton
    15 Apr 2012 | 7:00 pm
    Abstract: High resolution strain measurements are of particular interest in load bearing tissues such as the intervertebral disc (IVD), permitting characterization of biomechanical conditions which could lead to injury and degenerative outcomes. Magnetic resonance (MR) imaging produces excellent image contrast in cartilaginous tissues, allowing for image-based strain determination. Nonrigid registration (NRR) of MR images has previously demonstrated sub-voxel registration accuracy although its accuracy and precision in determining strain has not been evaluated. Accuracy and precision of…

  • Sensitivity of model predictions of muscle function to changes in moment arms and muscle–tendon properties: A Monte-Carlo analysis

    David C. Ackland, Yi-Chung Lin, Marcus G. Pandy
    15 Apr 2012 | 7:00 pm
    Abstract: Hill-type muscle models are commonly used in musculoskeletal models to estimate muscle forces during human movement. However, the sensitivity of model predictions of muscle function to changes in muscle moment arms and muscle–tendon properties is not well understood. In the present study, a three-dimensional muscle-actuated model of the body was used to evaluate the sensitivity of the function of the major lower limb muscles in accelerating the whole-body center of mass during gait. Monte-Carlo analyses were used to quantify the effects of entire distributions of perturbations in…

  • Detecting and quantifying global instability during a dynamic task using kinetic and kinematic gait parameters

    Eytan M Debbi, Alon Wolf, Amir Haim
    12 Apr 2012 | 7:00 pm
    Abstract: Objectives: Instability during gait can be identified in many different ways. Recent studies have suggested utilizing spatiotemporal parameters to detect instability during gait. Detecting instability using kinetic and kinematic gait parameters has not yet been examined fully. In addition, these studies have not yet identified measures that are capable of assessing the magnitude of instability. The objective of the present study was to identify kinetic and kinematic gait parameters that can best identify instability and quantify its magnitude.Methods: Ten healthy men underwent…

  • Microbubble-induced sonoporation involved in ultrasound-mediated DNA transfection in vitro at low acoustic pressures

    Yuanyuan Qiu, Chunbing Zhang, Juan Tu, Dong Zhang
    12 Apr 2012 | 7:00 pm
    Abstract: In the present work, human breast cancer cells MCF-7 mixed with polyethylenimine: deoxyribonucleic acid complex and microbubbles were exposed to 1-MHz ultrasound at low acoustic driving pressures ranging from 0.05 to 0.3MPa. The sonoporation pores generated on the cell membrane were examined with scanning electron microscopy. The transfection efficiency and cell viability were evaluated with flow cytometry. The results showed that ultrasound sonication under the current exposure condition could generate cell pores with mean size ranging from about 100nm to 1.25μm, and that larger…

  • San Franciso Plans to Take Back The Warriors

    The Golden State Warriors have been in the press the last few days. Reports indicate that city leaders in San Francisco are trying to seduce the NBA team to rejoin the Bay City. Mayor Ed Lee told Warriors executives that they would cater to their every need in hopes to bring the team to San Fran. in time for the first 2017 tip off. There are also talks of a new stadium that will be built if the team decides to return to its roots.  This would bring hundreds of jobs to the area and boost city revenue, something San Francisco residents are ecstatic about. However Oakland mayor Jean Quan is not…

  • Panel approves USC as LA Coliseum’s new lease-holder

    16 May 2012 | 7:29 am
    According to an LA Times report, USC is on the cusp on taking over control of the Los Angeles Memorial Coliseum. The Coliseum, which has been in dire financial straits for a few years, will now be controlled by USC, thanks to an 8-1 vote in favor of the move by the Los Angeles Memorial Coliseum Commission. The Coliseum has been in the hands of the public, or at least public officials, for the last 88 years. Under the terms of the agreement, USC would be given a new lease and the right to control the Coliseum and its revenue, until 2054, when the Coliseum Commission is set to dissolve and have…

  • New York Times Co. Sells Shares Again

      Due to declining ad revenue, New York Times Co. sold their remaining investment shares in Fenway Sports Group (owner of the Boston Red Sock) for $63 million cash.  The shares were spread among multiple eager buyers. Back in February, Times Co. sold a third of the shares in Fenway for $30 million. The New York Times have been struggling to keep their head above water as declining ad sales has caused the company stock to drop 1.2% to $6.43.  This year alone they have seen a 17% drop in share price, likely in part of increased popularity in internet companies such as Google Inc. and…

  • The USFL is officially back…for the first time.

    Dust off your old Birmingham Stallions jersey, the USFL is back. Well...sort of. The league which brought the world future NFL Hall-of-Famers such as Jim Kelly and Steve Young will begin play again next March. The new eight-team league will consist of a 14 game season. Separating the new USFL from the old USFL is that this new league, while the same in name, will consist of players who were not picked up by any NFL team, and will act as a developmental, off-season alternative to the NFL. Think of it almost like the NBA Developmental League, but for football. This new USFL will be run by…

  • Bowling collision simulation using Blender

    30 Apr 2012 | 9:05 pm
    For the past few months I have been developing a Matlab-based bowling-oriented physics engine for simulating the collisions of balls and pins, as well as the lane, gutters, and side walls.  This 'from-scratch' approach has provided much insight into collision detection and collision response, and has had some fruits.  Simulating 2-dimensional collisions (imagine an overhead view of a bowling lane) with or without friction accounts for many of the phenomena observed in bowling.  In particular, how pinball varies with the final lateral position and final heading of the ball is…

  • Identification of the benchmark canonical form

    1 Apr 2012 | 8:45 pm
    Model structure The identification of the linear dynamics of the bicycle can be formulated with respect to the benchmark canonical form realized in [Meijaard2007]. $$ M \ddot{q} + v C_1 \dot{q} + [g K_0 + v^2 K_2] q = T $$ where the time varying states roll and steer are collected in the vector \( q = [\phi \quad \delta]^T \) and the time varying inputs roll torque and steer torque are collected in the vector \(T = [T_\phi \quad T_\delta]^T\). I extend the equations to properly account for the lateral perturbation force, \( F \), which was the actual input we delivered during the experiments.

  • Robotic bike steer calibration

    8 Mar 2012 | 5:35 pm
    For the last few weeks, I have been working with Luke to produce a steer calibration program to run on the robotic bike. Much of this time involved me getting up to speed with how to actually program the STM32 and dealing with voltage comparator issues. The rotary encoder for tracking the steer angle has an index line which occurs once per full revolution. This is useful because we can take this incremental encoder and use it to find the steer angle at all times as opposed to only knowing angular velocity based on sequences of ticks and their timing.  The basic strategy is to put the…
