PURPOSE To evaluate prospectively the value of size, shape, margin and density in discriminating between benign and malignant CT screen detected solid non-calcified pulmonary nodules. MATERIAL AND METHODS This study was institutional review board approved. For this study 405 participants of the NELSON lung cancer screening trial with 469 indeterminate or potentially malignant solid pulmonary ...

Lithium-ion batteries (LIBs) have proven to be an efficient energy storage system in terms of their energy and power density, reliability and cyclability1. Today the state-of-the-art LIBs offer volumetric and gravimetric energy densities up to 770 Wh l−1 and 260 Wh kg−1, respectively, which was not expected 10 years ago. Unfortunately, the energy density of conventional LIBs will soon reach its...

Intel® X25-E and X25-M SATA Solid-State Drives have been designed to provide high performance and capacity density for use in applications which were limited by traditional hard disk drives (HDD), input/output (I/O) performance bottlenecks, or performance density (as defined by bandwidth and I/Os/sec per gigabyte, per Rack Unit (RU), per Watt required to power, and per thermal unit waste heat. ...

Polythiophenes are a popular class of organic conducting polymers, known for their environmental stability, conductivity [1], fluorescence and electroluminescent properties [2]. Conducting polymers, such as polythiophenes, have enormous potential in both static and dynamic applications, ranging from field-effect transistors and diodes to chemical sensors [3]. Many applications require the use o...

When the permittivities, or dielectric properties, of granular or powdered solid materials are important, some reliable relationship between the permittivity and the bulk density of the air-particle mixture is required. Examples of such applications include radio-frequency or microwave dielectric heating of these materials and the use of correlations between permittivity and water content of hy...

Architectures for focal plane image processing are discussed. On-chip image preprocessing for solid-state imagers using analog CCD circuits is described for low, medium, and high density detector arrays. A spatially parallel architecture for low density, high throughput applica­ tions is described. For sparse illumination or event detection, a content· addressable architecture is proposed. A ne...

Solid polymer electrolytes (SPEs) have become increasingly attractive in solid-state lithium-ion batteries (SSLIBs) recent years because of their inherent properties flexibility, processability, and interfacial compatibility. However, the commercialization SPEs remains challenging for flexible high-energy-density LIBs. The incorporation functional additives into could significantly improve elec...

The phase diagram of the Gay–Berne model with anisotropy parameters k53, k855 has been evaluated by means of computer simulations. For a number of temperatures, NPT simulations were performed for the solid phase leading to the determination of the free energy of the solid at a reference density. Using the equation of state and free energies of the isotropic and nematic phases available in the e...

Free energies and correlation functions of liquid and solid hard-sphere (HS) mixtures are calculated using the fundamental measure density functional theory. Using the thermodynamic perturbation theory the free energies of solid and liquid Lennard-Jones (LJ) mixtures are obtained from correlation functions of HS systems within a single theoretical approach. The resulting azeotrope- and spindle-...
