The Confederate Pension Systems in Texas, Georgia, and Virginia: The Programs and the People
… Unlike Texas, Georgia and Virginia provided artificial limbs for their veterans long before they started paying pensions. At the time of his enlistment in the 1860s, the typical future pensioner was twenty-five years of age, and fewer than half were married heads of households. Very few could …

Amphotericin B ion channels restore cystic fibrosis airway surface physiology
Just as artificial limbs replace the physical function of a missing arm or leg, small molecule surrogates acting as prosthetics on the molecular scale could replace protein functions that are either dysfunctional or absent in humans. These ‘molecular prosthetics’ could build upon and interface with …

Tailoring Artificial Muscles for the Design and Development of Soft Underwater Robots
… First, we start by characterizing unconventional artificial muscles used as the main actuators in the robots such as the twisted and coiled polymer fishing line (TCPFL) and NiTi shape memory alloy (SMA) actuators. As compared to current conventional actuators such as stepper motors and pnuematic …

Distributed force model for arbitrarily shaped IMPC actuators
… the relationship of an arbitrarily shaped artificial muscle to the force it produces does not currently exist for actuators made of ionic polymer-metal composites (IPMC), a type of electroactive smart material. The model in this thesis couples a finite element force simulation for IPMC with …

Kinematic analysis of compensation movements of upper limb amputees and able-bodied individuals during grasping movements
Upper limb prostheses users make compensatory movements to be able complete daily tasks. The primary compensation occurs from the next distal joint nearby the amputation. For transradial prosthesis users, the main compensatory movements often occur because of limited degrees of freedom and lack of …

Activity Monitor Accuracy for Lower-Limb Amputees Living in Colombia and Texas
<p>Maintaining physical activity for lower limb prosthesis wearers is important in order to reduce comorbidities and decrease physical function. Activity monitors can provide motivation for the wearer and outcome measurements for the health care professional. Two cohorts of lower extremity amputees …
