Abstract: A system of topographic patterns for the prevention of bacterial adhesion and biofilm formation. The patterns may be provided on the surfaces of certain devices that are prone to bacterial adhesion and biofilm formation, such as urinary catheters. To reduce bacterial adhesion and biofilm formation, and to remove existing biofilms, the patterns are induced to transform from a first topography to a second topography. For example, the surface patterns may be formed from a shape memory polymer and then heated to transform the patterns from the first topography to the second topography to dislodge bacteria and prevent fouling.
Abstract: A data processing method includes allocating a tag entry in a tag array for a data block; allocating a data entry in a data array for the data block when the data block is actively shared; and de-allocating the data entry when the data block is temporarily private or gets evicted in the data array.

Abstract: Orthopedic and dental implants coated with an antibacterial coating and methods of making and using, are described herein. The implant can be coated with a hydrophobic, polycationic antibacterial polymer. The polymer can be covalently or non-covalently associated with the surface; however, in particular embodiments, the polymer is non-covalently associated with the surface. As shown in the examples below, clinical observations, digital radiography, and a battery of well-accepted ex vivo analytical methods show that the presence of a hydrophobic polycationic polymer coating, such as N,N-dodecyl,methyl-PEI coating on the surface of a metal implant, was effective in eliminating the clinical signs of infection in vivo in a large animal infection model. Moreover, the coated plates supported bone healing, and in fact decreased healing times, even in the presence of significant bacterial contamination compared to a control.
