Toward Nanowire Electronics, Joerg Appenzeller, Joachim Knoch, Mikael Bjoerk, Heike Riel, Heinz Schmid, Walter Riess

Other Nanotechnology Publications

This paper discusses the electronic transport properties of nanowire field-effect transistors (NW-FETs). Four different device concepts are studied in detail: Schottky-barrier NW-FETs with metallic source and drain contacts, conventional-type NW-FETs with doped NW segments as source and drain electrodes, and, finally, two new concepts that enable steep turn-on characteristics, namely, NW impact ionization FETs and tunnel NW-FETs. As it turns out, NW-FETs are, to a large extent, determined by the device geometry, the dimensionality of the electronic transport, and the way of making contacts to the NW. Analytical as well as simulation results are compared with experimental data to explain …

Structures And Energetics Of Silicon Nanotubes From Molecular Dynamics And Density Functional Theory, Amritanshu Palaria, Gerhard Klimeck, Alejandro Strachan

PRISM: NNSA Center for Prediction of Reliability, Integrity and Survivability of Microsystems

We use molecular dynamics with a first-principles-based force field and density functional theory to predict the atomic structure, energetics, and elastic properties of Si nanotubes. We find various low-energy and low-symmetry hollow structures with external diameters of about 1 nm. These are the most stable structures in this small-diameter regime reported so far and exhibit properties very different from the bulk. While the cohesive energies of the four most stable nanotubes reported here are similar (from 0.638 to 0.697 eV above bulk Si), they have disparate Young's moduli (from 72 to 123 GPa).

The Battle Of Morgarten In 1315: An Essential Incident In The Founding Of The Swiss State, Albert Winkler

Swiss American Historical Society Review

Political realities in the German Empire at the beginning of the fourteenth century were harsh, and communities that wanted to gain or maintain their autonomy had to deal with serious external threats. Most frequently, this meant that military success was essential for survival. Many forces vied for authority, influence, and domination over the regions that formed the Swiss Confederation, which later developed into the modem state of Switzerland. The largest threat to Swiss sovereignty in this period was factions of nobles, most importantly the house of Habsburg, which were expanding their control over the region. By the early fourteenth century, …

Book Review: The Boat Is Full: Swiss Asylum Denied, Richard Hacken

Swiss American Historical Society Review

Das Boot ist voll (sometimes translated as "The Lifeboat is Full"), directed by Markus Imhoof, is a notable accomplishment in Swiss cinema of the late 20th century. It received the Silver Berlin Bear for Outstanding Single Achievement in 1981 at the Berlin International Film Festival, and the following year it was nominated for an Academy A ward in the category of Best Foreign Film. These honors presumably sprang not merely from recognition of Imhoof' s courage in recalibrating the past, in putting an alternate face on the Holocaust, and in documenting Swiss refugee policies during the Second World War. These …

Book Review: Lenin In Zurich, Axel Fair-Schulz, Katherine French

Swiss American Historical Society Review

The recent death of Alexander Solzhenitsyn on August 3rd of this year might prompt a fresh look at that writer's oeuvre. While Solzhenitsyn is mainly associated with well known works, such as One Day in the Life of Ivan Denisovich and The Gulag Archipelago, one should not neglect his less widely known books. Among those is his Lenin in Zurich. This volume should be of particular interest to readers engaged with all things Swiss, given its overt subject matter. One learns much about Switzerland in the early years of the last century as a major locus for Russian emigres. Solzhenitsyn …

Analysis Of Large-Scale Ocean Bottom Pressure Variability In The North Pacific, Don P. Chambers, Josh K. Willis

Marine Science Faculty Publications

[1] We use the leading empirical orthogonal functions (EOFs) of ocean bottom pressure (OBP) derived from an ocean model and the technique of EOF reconstruction to reduce noise in the large-scale OBP variations derived from the Gravity Recovery and Climate Experiment (GRACE). The subsequent OBP variations from the model and GRACE are then examined in the North Pacific between January 2003 and May 2007. Although annual and semiannual variations are similar, GRACE observes large interannual fluctuations poleward of 30°, where OBP increases from a low of nearly 3 cm below normal in early 2003 to normal throughout 2004 and 2005, …

Interaction Of Color And Sugar Concentration Preference With Aggression In Monteverde Cloud Forest Hummingbirds (Trochilidae), November 2008, Laurel Anne Mundy

Monteverde Institute: Tropical Ecology and Conservation

In Monteverde, Costa Rica, a number of hummingbird species coexist that are extremely important for pollination. Hummingbirds may prefer flowers of a certain color because they associate it with a higher nectar reward. They also may be territorial and defend especially rich food sources, dominant birds driving away all subordinates. The purpose of this study was to investigate color and sugar concentration preference in hummingbirds using artificial feeders, and to determine whether dominance and aggression has an effect on food choice. Many hummingbird-pollinated flowers are red, so I hypothesized that all species would show a preference, and predicted that all …

Regulation Of Photosynthetic Pigments In Tropical Understory And Gaps, November 2008, Maiken Westphal

Monteverde Institute: Tropical Ecology and Conservation

A plant can manipulate its absolute and relative amounts of photosynthetic pigments in different light environments (Hopkins, 1995, Goncalves and Vieira, 2001). Leaf samples from ten gap and ten understory plants were collected from Calyptrogyne brachystachys (Arecaceae), Heliconia monteverdensis (Heliconiaceae), and Piper ariteum (Piperaceae), and their chlorophylls a, b, and carotenoid concentrations were found. The total concentration of chlorophylls a, b, total chlorophyll and carotenoids were significantly higher (p = <0.05) in the understory leaf samples of C. brachystachys and P. auriteum, but higher in the gap samples of H. monteverdensis. Ratios of chlorophyll a to chlorophyll b were significantly greater for gap samples of all three species. A higher concentration of chlorophyll and carotenoids in the understory plants of C. brachystachys and P. auriteum suggests they are adjusting the absolute and relative amounts of pigments to make use of sparse light in the understory. H. monteverdensis utilizes its photosynthetic pigments slightly differently, acting much like a canopy plant.

Water Use, Wastewater Disposal, And Water Conservation Attitudes In The Monteverde Zone, November 2008, Jenna Rasmusson

Monteverde Institute: Tropical Ecology and Conservation

The residents of the zone of Monteverde, Costa Rica represent a wide array of demographics and other factors such as income, education level, town of residence, and water source, which may impact their water use, wastewater disposal, and water conservation attitudes. In order to study these relationships, a survey was conducted in four different Monteverde towns. The survey consisted of questions on demographic variables, water consumption patterns, methods of disposal, and water shortages, and lastly, addressed attitudes toward water conservation. Data were collected from 64 surveys and analyzed using regression analyses and chi-squared tests. Thirteen significant results and several trends …

Asymmetry Of Floral Structures And The Possibility Of Self-Pollination In Oerstedella Exasperata (Orchidaceae), November 2008, Lindsay Brownell

Monteverde Institute: Tropical Ecology and Conservation

The purpose of this study was to investigate the causes of the pervasive asymmetry found in the neotropical orchid Oerstedella exasperata. Previous studies have found that high levels of asymmetry decrease reproductive success, and can be caused by a high amount of homozygosity within a population. This study tested the ability of O. exasperata to self-pollinate, a condition that indicates the possibility of a high level of homozygosity. In addition, the relationships between three degrees of asymmetry and floral color, floral mass, plant size and sun exposure were investigated to determine whether higher asymmetry is correlated with lower reproductive success …

The Effect Of Reward And Color Pattern On Butterfly Foraging In Lantana Camara (Verbenaceae), November 2008, Jenna Short, Tara Florida

Monteverde Institute: Tropical Ecology and Conservation

Lantana camara has inflorescences composed of young, nectar-producing yellow flowers surrounded by older orange flowers that no longer produce nectar (Moldenke 1973). We examined the relationship between L. camara and its butterfly pollinators to see if the preference for yellow flowers (Peters 1998) is innate or learned. Further, we altered the position of flower color on the inflorescence to see if the normal yellow-centered bull’s eye pattern increased visitation over other patterns. We collected data for butterflies foraging on L. camara with six patterns of yellow and orange flowers by painted these colors on the inflorescences. Next, we watched these …

The Altruistic Cardinal?, Paul A. Johnsgard

Paul Johnsgard Collection

Cardinals also are known for their intense parental behavior. Most feeding of fledged young is done by the males, since females typically begin a new nesting cycle very shortly after their first young fledge. I’ve seen male cardinals feed female cardinals, cowbirds and house finches. One researcher in Oklahoma reported a cardinal attempting to feed goldfish in a pond! While photographing backyard birds in Lincoln, I noticed that a male cardinal was tending to a single newly fledged cardinal chick, but also was being constantly pestered by two young house finches. Cardinals raise their young on insects while house finch …

Mortalités, Effondrements Et Affaiblissements Des Colonies D’Abeilles, Julie Chiron, Anne-Marie Hattenberger

Entomology Papers from Other Sources

Depuis plusieurs dizaines d’années, une diminution notoire des populations de pollinisateurs a été signalée dans de nombreux pays par les professionnels et les scientifiques. L’enjeu économique et écologique représenté par la perte de ces individus a déterminé la mise en oeuvre de nombreuses études sur le sujet. Plusieurs hypothèses de facteurs de risques ont été avancées pour tenter d’expliquer ce phénomène. En France, notamment, les apiculteurs ont alerté les pouvoirs publics quant à un effet potentiel de certains traitements phytopharmaceutiques à usage agricole sur la vitalité des colonies d’abeilles domestiques (Apis mellifera), entraînant la décision par le Ministre …

Speak Softly...With Everyone You Can, Todd Landman

Human Rights & Human Welfare

From the Monroe Doctrine to the Bush Doctrine, United States foreign policy has been predicated on the assumption that somehow it knows what is best for the rest of the world. Monroe feared a potential encroachment from Russia and meddling in the "American" Hemisphere by the European powers and issued what originally appeared as a modest statement about resistance to intervention by any other country than the United States . Ironically enforced by the British Navy at that time, the Monroe Doctrine went far beyond its modest beginnings to set a precedent for the development of U.S. foreign policy. The …

Therapeutic Challenges Of Multi-Being, Kenneth J. Gergen

Psychology Faculty Works

This paper emerges from an attempt to shift the locus of understanding human action from the individual to relationship. In doing so we come to see persons as multi-beings, that is, as constituted within multiple relationships from which they emerge with multiple, incoherent, and often conflicting potentials. Therapy, in this context, becomes a collaborative relationship with the aim of transforming the client's broader relational network. In this view, schooling in a singular practice of therapy artificially limits the therapist's potential, and thus the possible outcomes of the client–therapist relationship. Invited, then, is a reflective eclecticism, in which the myriad potentials …

Challenges And Questions Concerning “Culturally-Sensitive Design”, Ross Perkins

Educational Technology Faculty Publications and Presentations

Since the inception of the field of anthropology, scholars have debated the definition for the word "culture." Lonner and Adamapoulos (1997) note that "there are 200 or more definitions of 'culture' in the literature of the social sciences, not one of which has been embraced by a substantial number of social scientists" (p. 76). Strauss and Quinn (1997) provide an overview of four schools of thought regarding the interpretations of "culture":

"Geertzian interpretivists have stressed the publicness of meaning, cognition, and culture. Foucauldian postmodernists have argued for the constructedness of culture and of the self. Some contemporary historical materialists highlight …

Endoplasmic Reticulum Stress Markers Are Associated With Obesity In Nondiabetic Subjects, Neeraj K. Sharma, Swapan K. Das, Ashis K. Mondal, Oksana Hackney, Winston S. Chu, Philip A. Kern, Neda Rasouli, Horace J. Spencer, Aiwei Yao-Borengasser, Steven C. Elbein

Clinical and Translational Science Faculty Publications

Objective: Adipocyte and hepatocyte endoplasmic reticulum (ER) stress response is activated in dietary and genetic models of obesity in mice. We hypothesized that ER stress was also activated and associated with reduced insulin sensitivity (S_I) in human obesity.

Research Design and Methods: We recruited 78 healthy, nondiabetic individuals over a spectrum of body mass index (BMI) who underwent oral and iv glucose tolerance tests, and fasting sc adipose and muscle biopsies. We tested expression of 18 genes and levels of total and phosphorylated eukaryotic initiation factor 2α, c-jun, and c-Jun N-terminal kinase 1 in adipose tissue. We compared …

Stearoyl-Coenzyme A Desaturase 1 Gene Expression Increases After Pioglitazone Treatment And Is Associated With Peroxisomal Proliferator-Activated Receptor-Γ Responsiveness, Aiwei Yao-Borengasser, Negah Rassouli, Vijayalakshmi Varma, Angela M. Bodles, Neda Rasouli, Resat Unal, Bounleut Phanavanh, Gouri Ranganathan, Robert E. Mcgehee Jr., Philip A. Kern

Clinical and Translational Science Faculty Publications

Context and Objective: Stearoyl-coenzyme A desaturase (SCD1) is the rate-limiting enzyme that converts palmitoyl- and stearoyl-coenzyme A to palmitoleoyl- and oleoyl-cownzyme A, respectively. SCD-deficient mice are protected from obesity, and the ob/ob mouse has high levels of SCD. This study was designed to better characterize SCD1 gene and protein expression in humans with varying insulin sensitivity.

Design, Participants, and Setting: In a university hospital clinical research center setting, SCD1 gene expression was measured in sc adipose and vastus lateralis muscle of 86 nondiabetic subjects; 10 wk of pioglitazone (45 mg daily) and metformin (1000 mg twice daily) treatment were assessed …

Morphology Of The Dayside Ionosphere Of Venus: Implications For Ion Outflows, Jane L. Fox

Physics Faculty Publications

The nightside ionosphere of Venus is formed mostly by day-to-night transport of ions below the ionopause, with a small contribution from precipitation of energetic electrons from the wake. This nightward flux of ions should result in dayside ionospheres that are characterized by smaller electron density scale heights at high altitudes than those that are characteristic of diffusive equilibrium. In order to determine both the maximum possible values of the upward fluxes and the upward fluxes implied by comparison of our computed ion and electron density profiles to measurements, we have constructed more than 60 models of the high solar activity …
