Addition of 1.0 equiv of Ph3SiH to [Cp*(PMe3)Rh(Me)(CH2Cl2)]+BAr'4- (1) resulted in release of methane and quantitative formation of [Cp*(PMe3)Rh(SiPh3)(CH2Cl2)]+BAr'4- (2). Subsequent addition of 1.0 equiv of MeCN to 2 caused immediate displacement of dichloromethane to form the eta1-nitrile adduct [Cp*(PMe3)Rh(SiPh3)(NCMe)]+BAr'4- (3). Upon standing at room-temperature overnight, complex 3 co...

Two-dimensional (2D) bar codes were designed to carry significantly more data with higher information density and robustness than its 1D counterpart. Thanks to the popular combination of cameras and mobile phones, it will naturally bring great commercial value to use the camera phone for 2D bar code reading. This paper addresses the problem of specific 2D bar code design for mobile phones and i...

BAR domains are highly conserved protein domains participating in a diversity of cellular processes that involve membrane remodeling. The mechanisms underlying such remodeling are debated. For the relatively well-studied case of amphiphysin N-BAR domain, one suggested mechanism involves scaffolding, i.e., binding of a negatively charged membrane to the protein's positively charged curved surfac...

Like the majority of spiral galaxies, the Milky Way contains a central non-axisymmetric bar component. Our position in the Galactic plane renders it rather hard to see, but also allows us to make measurements of the bar that are completely unobtainable for any other system. This paper reviews the evidence for a bar that can be gleaned from the many extensive surveys of both gas and stars in the...

Let S = {l1, l2, l3, . . . , ln} be a set of n vertical line segments in the plane. Though not essential, to simplify proofs we assume that no two li’s are on the same vertical line. A convex polygon weakly intersects S if it contains a point of each line segment on its boundary or interior. In this paper, we propose an O(n log n) algorithm for the problem of finding a minimum area convex polyg...

Even if drugs are accurately dispensed, it is difficult to ensure their safety in the absence of an error-free medication system when or after drugs are given to patients. In particular, most powders are white and are impossible to distinguish based on appearance after they are placed in powder packages. In this study, we newly developed a system in which prescription order information is bar-c...

In two-dimensional Euclidean space, we examine behaviour of an arc when it crosses a vertical line. There are three types when an arc enters into a line, which are: “Left-In”, “Right-In” and “Oscillating-In”. Also, there are three types when an arc goes out from a line, which are: “Left-Out”, “Right-Out” and “Oscillating-Out”. If an arc is a special polygonal arc, there are only two types for e...

Elimination of medical errors is important for pathologists. Errors occurring in surgical pathology involve specimen defects, specimen labeling, processing, diagnosis, and reporting defects. Errors occur during prelaboratory, laboratory, and postlaboratory phases. We reviewed our experience with mislabeled specimens in the laboratory for an 18-month period. The percentage of error was calculate...

Species identification of earthworms is usually achieved by careful observation of morphological features, often sexual characters only present in adult specimens. Consequently, juveniles or cocoons are often impossible to identify, creating a possible bias in studies that aim to document species richness and abundance. DNA barcoding, the use of a short standardized DNA fragment for species ide...

DNA barcoding, an inventory of DNA sequences from a standardized genomic region, provides a bio-barcode for identifying and discovering species. Several recent studies suggest that the sequence diversity in a 648 bp region of the mitochondrial gene for cytochrome c oxi- dase I (COI) might serve as a DNA barcode for identify- ing animal species such as North American birds, in- sects and fishes....
