Repairing for death he targets of cytotoxic T lymphocytes (CTLs) determine their own mode of death, say Dennis Keefe, Judy Lieberman, and colleagues (Harvard Medical School, Boston, MA). The dying cells patch themselves up so that rapid and messy necrosis is avoided in favor of a more lengthy and controlled apoptosis. The CTLs deliver their insult in the form of perforin, a pore-forming protein...

The GroundWater Remediation Technologies Analysis Center (GWRTAC) is a national environmental technology transfer center that provides information on the use of innovative technologies to clean-up contaminated groundwater. Established in 1995, GWRTAC is operated by the National Environmental Technology Applications Center (NETAC) in association with the University of Pittsburgh's Environmental ...

BACKGROUND Compliant flooring, broadly defined as flooring systems or floor coverings with some level of shock absorbency, may reduce the incidence and severity of fall-related injuries in older adults; however, a lack of synthesized evidence may be limiting widespread uptake. METHODS Informed by the Arksey and O'Malley framework and guided by a Research Advisory Panel of knowledge users, we ...

A novel syntax-compliant encryption primitive and an efficient syntax-compliant JPEG 2000 encryption scheme are presented in this paper. The syntax-compliant encryption primitive takes, as input, syntax-compliant plaintext and produces syntax-compliant ciphertext. It is faster than all the other syntax-compliant encryption primitives we know. Our JPEG 2000 encryption scheme encrypts independent...

This paper presents the experimental evaluation of contact/impact dynamics between a space robot with a compliant wrist and a free-flying object. In capturing a target satellite by a free-flying space robot, a robot must prevent bounce-off of a target satellite from the operational space of the robot due to hard collision. In order to avoid hard collision, the authors propose the use of a stiff...

High mortality from invasive cervical cancer among Mexican-descent Latinas living in the Great Plains could be substantially reduced if they would utilize screening procedures regularly. To understand possible influential factors on their screening behaviors, we investigated which variables differentiate women age 50 and older who are most compliant with cervical cancer screening guidelines fro...

Compliant fish skin is effectively in reducing drag, thus the design and application of compliant bionic materials may be a good choice for drag reduction. Here we consider the drag reduction of compliant bionic materials. First, ZnO and PDMS mesh modified with n-octadecane were prepared, the drag reduction of self-texturing compliant n-octadecane were studied. The results show that the mesh mo...

Compliant Mechanism has been designed for various types of application to transmit desired force and motion. In this study, we have explored an application of Compliant Mechanism for passive vibration isolation systems, for which compliant isolator is used to cancel undesired disturbance, which results in attenuated output amplitude. The Compliant Mechanism is equipped with isolator, which acts...

The handling of Interoperable Object Group References (IOGRs) is one of the basic building block of any FTCORBA compliant platform. In this paper we introduce two basic components: IOGRManager, a tool to create, update, browse IOGRs, and an Object-Request-GateWay (ORGW), a CORBA compliant client request interceptor, which allows clients running on non-FT-Corba compliant ORBs to transparently in...

We report on the embedding of a domain specific language, (X)HTML, into Haskell and demonstrate how this superficial non-context-free language can be represented and rendered to guarantee World Wide Web Consortium (W3C) compliance. Compliance of web content is important for the health of the Internet, accessibility, visibility, and reliable search. While tools exist to verify web content is com...
