Identification of the dominant precession damping mechanism in Fe, Co, and Ni by first-principles calculations

The Landau-Lifshitz equation reliably describes magnetization dynamics using a phenomenological treatment of damping. This paper presents first-principles calculations of the damping parameters for Fe, Co, and Ni that quantitatively agree with existing ferromagnetic resonance measurements. This agreement establishes the dominant damping mechanism for these systems and takes a significant step toward predicting and tailoring the damping constants of new materials.Comment: 4 pages, 1 figur

Verbal Response Modes in Action:Microrelationships as the Building Blocks of Relationship Role Dimensions

Dimensions of interpersonal relationships, such as attentiveness, directiveness, and presumptuousness, have typically been assessed through impressionistic ratings or by aggregate scores derived from coding of specific (e.g., verbal) behaviors. However, the meanings of these dimensions rest on the interpersonal microrelationships that are actually observed by the raters or coders. In this qualitative study, the way these global relationship qualities were built from microrelationships at the utterance level was examined in passages from one medical interaction. Applications of microrelationships to future communications research are suggested

Microwave remote sensing of snow experiment description and preliminary results

The active and passive microwave responses to snow were investigated at a site near Steamboat Springs, Colorado during the February and March winter months. The microwave equipment was mounted atop truck-mounted booms. Data were acquired at numerous frequencies, polarizations, and angles of incidence for a variety of snow conditions. The experiment description, the characteristics of the microwave and ground truth instruments, and the results of a preliminary analysis of a small portion of the total data volume acquired in Colorado are documented

Convergence and Divergence of Themes in Successful Psychotherapy: An Assimilation Analysis

Theme convergence is the linking of seemingly unrelated problem domains as they advance through assimilation stages-a developmental sequence of cognitive and affective changes through which problematic content is hypothesized to pass during successful psychotherapy. Theme divergence is the contradiction or conflict of solutions to different problems, so that progress in one domain leads to stagnation or regression in another domain. An intensive qualitative method called assimilation analysis was used to examine theme convergence and divergence in a successful psychodynamic psychotherapy with a 20–yr–old female patient. Because specific problems often fail to progress monotonically, even in successful psychotherapy cases, it is suggested that clients\u27 problems cannot be resolved in isolation; instead, they may influence each other toward resolution or stagnation in complex and unpredictable ways

Phenolic cutter for machining foam insulation

Pre-pregged fiber glass is an efficient abrasive for machining polystyrene and polyurethane foams. It bonds easily to any cutter base made of aluminum, steel, or phenolic, is inexpensive, and is readily available

Aspen Modern: America’s International Resort

The Aspen Modern event held on July 28, 2010 was presented by the National Trust for Historic Preservation, in partnership with the City of Aspen Community Development Department, the Aspen Art Museum, the Aspen Historical Society, the Aspen Institute, and Spring Board Aspen, with support from the National Endowment for the Arts and the Henry Luce Foundation. This full-color booklet highlights the modern architecture of Aspen, Colorado
