Nonlinear dynamics of ionization stabilization of atoms in intense laser fields
We revisit the stabilization of ionization of atoms subjected to a
superintense laser pulse using nonlinear dynamics. We provide an explanation
for the lack of complete ionization at high intensity and for the decrease of
the ionization probability as intensity is increased. We investigate the role
of each part of the laser pulse (ramp-up, plateau, ramp-down) in this process.
We emphasize the role of the choice for the ionization criterion, energy versus
distance criterion
Advanced Atomic Force Microscopy for BioMaterials Research
Optical microscopy uses the interactions between light and materials to provide images of the microscopic world. It is widely employed in science to study the behavior and properties of microscopic organisms and cells. Atomic force microscopy (AFM) is a technique for obtaining images of the surfaces of materials at the atomic to micrometer scales. AFM operates by rastering an ultra-sharp needle across a sample surface and recording the height of the needle at each position. While AFM can provide atomic resolution images of the contours (topography) of a surface, it can also perform extremely sensitive measurements of surface mechanical properties. By fabricating custom AFM probes, the mechanical properties of specific locations of living cells can be studied and manipulated. In addition, high-speed imaging of biological materials can provide images of changes to cellular surfaces in response to chemical or electrical signals. This poster will present examples and applications of advanced AFM capabilities for research in biomaterials available in the Boise State University Surface Science Laboratory

Futility in acute care surgery: first do no harm.
The consequences of the delivery of futile or potentially ineffective medical care and interventions are devastating on the healthcare system, our patients and their families, and healthcare providers. In emergency situations in particular, determining if escalating invasive interventions will benefit a frail and/or severely critically ill patient can be exceedingly difficult. In this review, our objective is to define the problem of potentially ineffective care within the specialty of acute care surgery and describe strategies for improving the care of our patients in these difficult situations
