 | Memristive devices have become very popular in recent years due to their potential to dramatically alter logic processing in CMOS circuitry. Memristive devices function as electrical potentiometers, allowing for such diverse applications as memory storage, multi-state logic, and reconfigurable logic gates. This research covered the fabrication, characterization, and modeling of Al/CuxO/Cu memristive devices created by depositing Al top electrodes atop a CuxO film grown using plasma oxidation to grow the ... |

| In the first year, we made eighteen new 21,23-core modified porphyrins, determined their photophysical properties, and evaluated the biological properties of them. In the second year, the research focused on 1) analyzing quantitative structure-activity relationships (QSAR) of the porphyrins prepared in the first year, 2) establishing new synthetic methods for novel structures and preparing them. In the third year, the structures of two derivatives were determined unambiguously be x-ray crystallography. ... |

|
| Excitotoxicity is one of the leading causes for amyotrophic lateral sclerosis (ALS). Our goal was to develop a novel class of powerful aptamer-based anti-excitotoxic inhibitors against GluR2Qflip a key AMPA receptor subunit that controls the calcium permeability and mediates excitotoxicity. An aptamer is a single-stranded nucleic acid that directly inhibits a protein's function by folding into a specific tertiary structure that dictates high-affinity binding to the target protein. To date ... |

| We propose an iterative generalized least squares procedure to recover unknown messages hidden in image hosts via spread-spectrum embedding. Neither the original host nor the embedding signature is assumed available. We demonstrate that for hidden messages of sufficient length (data sample support), recovery can be achieved with probability of error close to what may be attained with known embedding signature and known original host autocorrelation matrix. For small hidden messages, ... |

| The prevalence of breast cancer is greatest in industrialized regions, and exposure to light at night has been proposed as a potential risk factor. Modulation of melatonin secretion by light has been implicated in the causal pathway linking exposure to light and breast cancer risk. Recent evidence indicates that melatonin is a natural oncostatic agent capable of functioning through a variety of anti-proliferative, anti-oxidative, and immunostimulatory mechanisms. The authors propose ... |

|
| Polycapillary x-ray optics, arrays of hollow capillary tubes used to guide x rays by total reflectance, have been shown to have potential in medical imaging at mammographic energies. Placing these optics after the object to be imaged provides very efficient rejection of Compton scatter because of the low angular acceptance of the capillaries. A Polycapillary tapered optic produced reduction in scatter fraction of a factor of 5 at 27 keV ... |

| There is experimental evidence showing that a sedentary life-style and high fat diet induce estrogen metabolism toward 1 6 alpha hydroxylation leading to biologically potent metabolites (estriol and 16 alpha hydroxyestrone) . An active life-style and a low fat diet induce the alternative 2-hydroxylation with production of weak estrogen metabolites (2-hydroxyestrone). Potent estrogens may increase prostate cell division and increase prostate cancer risk. The research hypothesis is that the preferential ... |

|
| Monochromatic imaging is typically done with synchrotron sources. These sources are expensive and not practical for clinical settings. However, conventionaI laboratory sources normally have insufficient intensity. Polycapillary x-ray optics can be used to efficiently produce an intense parallel beam, which can be diffracted from a crystal to create monochromatic radiation. Monochromatic parallel beam imaging produces high subject contrast, high resolution, and low patient dose. Contrast, resolution, and intensity measurements were ... |

| The kinetics of the wet oxidation process of MBE-grown high-Al-content AlAs/Al(0.6)Ga(0.4)As short-period superlattices (SPSLs) was investigated and compared to AlGaAs alloys and pure AlAs. We found that alloys and superlattices (SLs) have different oxidation characteristics. These differences were attributed to traces of the superlattice structure in the oxidized material. The microstructure and chemistry of SPSLs with an equivalent composition of Al(0.98)Ga(0.02)As was studied, using transmission electron microscopy, energy-dispersive x-ray spectroscopy, ... |

| Results of extensive mammography screenings have shown the need for detection of breast cancer at earlier and more curable stages to have any significant impact on the mortality rate. While new imaging technologies for breast cancer diagnosis like magnetic resonance imaging, breast ultrasound and breast specific positron emission tomography are being developed, x%ray imaging continues to function as a convenient and economical choice for early detection. |

It appears even possible that high tropospheric ice crystals may occasionally exhibit such habit. That would be consistent with rare, but reliable observations of the Scheiner's halo. In the case of noctilucent clouds, however, it is doubtful that the crystal habit is after all of much practical importance, because due to low ... |
