Tunneling of Cooper pairs across voltage biased asymmetric single-Cooper-pair transistors

We analyze tunneling of Cooper pairs across voltage biased asymmetric single-Cooper-pair transistors. Also tunneling of Cooper pairs across two capacitively coupled Cooper-pair boxes is considered, when the capacitive coupling and Cooper pair tunneling are provided by a small Josephson junction between the islands. The theoretical analysis is done at subgap voltages, where the current-voltage characteristics depend strongly on the macroscopic eigenstates of the island(s) and their coupling to the dissipative environment. As the environment we use an impedance which satisfies Re[Z]<<R_Q and a few LC-oscillators in series with Z. The numerically calculated I-V curves are compared with experiments where the quantum states of mesoscopic SQUIDs are probed with inelastic Cooper pair tunneling. The main features of the observed I-V data are reproduced. Especially, we find traces of band structure in the higher excited states of the Cooper-pair boxes as well as traces of multiphoton processes between two Cooper-pair boxes in the regime of large Josephson coupling.Comment: 9 pages, 9 figures, Revtex

RECASTING EPIC TRADITION THE DISPOSSESSED AS HERO IN SANDOZ\u27S \u3ci\u3eCRAZY HORSE\u3c/i\u3e AND \u3ci\u3eCHEYENNE AUTUMN\u3c/i\u3e

Although Mari Sandoz is perhaps best known for the biography of her Nebraska pioneer father, Old Jules (1935), her two other biographies, Crazy Horse: The Strange Man of the Oglalas (1942) and Cheyenne Autumn (1953), equally convey her distinctive historical vision of the American West. In these two works, Sandoz rewrites traditional epic formula, taking the perspective of the dispossessed Lakotas and Cheyennes and recounting not the growth and expansion of a culture, but its conquest. In spite of material defeat at the hands of dominant white society, her Native American leaders assume heroic stature, striving against all odds to preserve their people and culture

Visionaries of the American West : Mari Sandoz and Her Four Plains Protagonists

The authorial reputation of Mari Sandoz has long rested in the shadow of other writers of her era. First of all, Sandoz wrote from and about a relatively remote region of the United States. In addition, she firmly refused to produce popular works at the expense of sacrificing the truth she perceived and wished to express. Consequently, Sandoz has often been classified as a regional writer and her works have been overlooked by many readers and critics. Her status as a woman, her unconventional writing style, point of view, and subject matter, and the blending of historical and fictional elements in her works have variously tended to hinder Sandoz\u27s reputation as a literary artist. Although her works received national reviews and careful scrutiny from western critics and historians, and recently from feminists, critical recognition has generally eluded Sandoz..

Numerical Study of Wave Propagation in Uniaxially Anisotropic Lorentzian Backward Wave Slabs

The propagation and refraction of a cylindrical wave created by a line current through a slab of backward wave medium, also called left-handed medium, is numerically studied with FDTD. The slab is assumed to be uniaxially anisotropic. Several sets of constitutive parameters are considered and comparisons with theoretical results are made. Electric field distributions are studied inside and behind the slab. It is found that the shape of the wavefronts and the regions of real and complex wave vectors are in agreement with theoretical results.Comment: 6 pages, figure

Fitting Women to Their Work: The Vocational Vision of Helen M. Bennett

A WOMAN CAN DO ANYTHING IF SHE PUTS HER MIND ON IT. \u27 This conviction propelled the career choices of Helen Marie Bennett in the late nineteenth and early twentieth centuries and the vocational message she communicated. Bennett commenced her wide-ranging life\u27s pursuits in western South Dakota, where she was raised, and brought them to culmination in Chicago, where she became a leader in the emerging field of vocational guidance. She firmly believed that all paths should be open to women and that women had a responsibility to find and follow their own vocation. Bennett\u27s life experiences and interests sparked and shaped her career counseling work and led her to stage the Woman\u27s World\u27s Fair, held annually in Chicago from 1925 to 1928. The all-female enterprise stood as a visual portrayal of the achievements of women in an expanding range of occupations. We are simply trying to show women what they can do . . . [and] to point the way for the women of tomorrow, she stated.^ The story of Bennett\u27s work to help women name and fulfill their life\u27s callings demonstrates the significant role she played in the vocational guidance movement as it developed in the early twentieth century. Her background, formed through the westward expansionist experience and its legacy of dispossession, would color and complicate her outlook and the imagery she used as she lectured and wrote on vocation. Her message, taken to its full potential, however, evinced a vision of inclusivity and equal opportunities for all

Oncology Nurses\u27 Perceptions of Self-Compassion: a Pilot Study

Oncology nurses face extraordinary stressors in their work. If this stress becomes prolonged, these nurses are at risk for burnout and compassion fatigue. One effective way for nurses to manage stress is to care for themselves, body, mind, and spirit. The concept of self-compassion reflects a meaningful approach to self-care. This pilot study explored the perception\u27of self-compassion by hospital based oncology nurses. A convenience sample of 37 oncology nurses was surveyed using four demographic questions and the Self-Compassion Scale by Kristin Neff. The results demonstrated positive correlation between years of nursing experience and years of oncology nursing experience with common humanity, one aspect of self-compassion. Further research about self-compassion and nurses may help to increase nurses\u27 understanding of self-care and effective workplace stress management
