The structure and local structural distortions, through the polarization manipulation, of crystalline films of ferroelectric vinylidene fluoride (70%) with trifluoroethylene (30%) [P(VDF-TrFE)] copolymer on graphite were studied by scanning tunneling microscopy (STM). A quasispiral twist in CuC bonds with rotations about the polymer chain axis was observed by high-resolution STM, indicating a s...

BACKGROUND Resource-constrained triage occurs when the number of trauma patients exceeds the capacity for simultaneous transport and treatment. The objective of this article is to apply a new resource-constrained triage method (denoted Sacco triage method [STM]) to victims of penetrating trauma and compare it with existing methods. METHODS STM is a mathematical model of resource-constrained t...

This paper is devoted to the control system design for high performance scanning tunneling microscope (STM). A common approach by scanning probe community is to use conventional proportional integral (PI) control design to control the vertical movement of STM tip (z-direction). In this article, a modern H∞ control design is analyzed in order to obtain the dual purpose of ultrahigh positioning a...

Pseudo-code descriptions of STMs assume sequentially consistent program execution and atomicity of high-level STM operations like read, write, and commit. These assumptions are often violated in realistic settings, as STM implementations run on relaxed memory models, with the atomicity of operations as provided by the hardware. This paper presents the first approach to verify STMs under relaxed...

The aim of the present study was to examine if soluble thrombomodulin (sTM) and von Willebrand factor (VWF) could predict a first-ever ischemic or hemorrhagic stroke. This study was an incident case-referent study from within a population-based cohort in northern Sweden. Up to 1996 about 44,000 subjects had been screened and stroke cases were classified according to the WHO MONICA criteria. A f...

BACKGROUND Salmonella Typhimurium (STm) remain a prominent cause of bacteremia in sub-Saharan Africa. Complement-fixing antibodies to STm develop by 2 years of age. We hypothesized that STm-specific CD4⁺ T cells develop alongside this process. METHODS Eighty healthy Malawian children aged 0-60 months were recruited. STm-specific CD4⁺ T cells producing interferon γ, tumor necrosis factor α, an...
