Traumatic intracranial aneurysms (TICAs) are rare and are associated with high rates of morbidity and mortality. TICAs usually result from head injuries caused by traffic accidents, industrial accidents, or gunshots. We report a traumatic aneurysm of the callosomarginal artery-cortical artery junction arising from a penetrating injury by scissors. A 51-year-old woman was admitted to our hospita...

The study of game theory focuses on games between players which may be anything from individuals, businesses, governments, or competing populations of animals. Each player has a set of n moves {E1, E2, . . . , En} from which they form a strategy. These are either pure strategies in which a player always plays one move, or mixed strategies de ned as a probability distribution over their moves, i...

The “Haptic Scissors” is a device that creates the sensation of cutting in virtual environments. The scissors have two degrees of freedom of motion and force feedback, one for cutting (single blade rotation) and one for translation. An algorithm was developed to simultaneously display translational and cutting forces for a realistic cutting simulation. In previous work, we used filtered data fr...

Sum rules for the totaland scissors-mode M1 strength in odd-A nuclei are derived within the single-j interacting boson-fermion model. We discuss the physical content and geometric interpretation of these sum rules and apply them to Er and Dy. We find consistency with the former measurements but not with the latter. 21.60.Fw, 21.10.Re, 23.20.-g, 27.70.+q Typeset using REVTEX 1 The orbital magnet...

We present a general strategy for designing proteins to recognize DNA sequences and illustrate this with an example based on the "Y-shaped scissors grip" model for leucine-zipper gene-regulatory proteins. The designed protein is formed from two copies, in tandem, of the basic (DNA binding) region of v-Jun. These copies are coupled through a tripeptide to yield a "dimer" expected to recognize th...

Some patients with frontotemporal lobar degeneration (FTLD) have shown the development of painting or musical abilities after the onset of the disease. In this report, we present another emergent ability. A female patient with FTLD showing dense atrophy of the bilateral anterior lobes and a loss of voluntary activity in aspects of daily living, presented with the characteristic behaviours when ...

The surface of gutta-percha cones was evaluated after using five different cutting methods, including a new TipSnip device. The gutta-percha cones were cut off using: 1) TipSnip, 2) a single cut with a scalpel blade using a gauge, 3) two cuts with a scalpel blade using a gauge, 4) a razor blade against a glass slab or 5) scissors. Samples were examined under stereomicroscopy and observed by thr...

Low-energy M1 strength functions of ^{60,64,68}Fe are determined on the basis of large-scale shell-model calculations with the goal to study their development from the bottom to the middle of the neutron shell. We find that the zero-energy spike, which characterizes nuclei near closed shells, develops toward the middle of the shell into a bimodal structure composed of a weaker zero-energy spike...

Molecular scissors engineered for site-specific modification of the genome hold great promise for effective functional analyses of genes, genomes and epigenomes and could improve our understanding of the molecular underpinnings of disease states and facilitate novel therapeutic applications. Several platforms for molecular scissors that enable targeted genome engineering have been developed, in...
