Strain-based Blood Damage Estimation for Computational Design of Ventricular Assist Devices
Authors: Gesenhues Linda , Pauli Lutz , Behr Marek
Published: April 2016

Aims

Computational fluid dynamics (CFD) is used to predict damage of red blood cells (RBCs) in ventricular assist devices (VADs). The damage is measured by the hemoglobin ratio in the blood plasma.

Methods

A power law is used to relate the hemoglobin ratio to shear stress and exposure time. For the shear stress measure, the common stress-based model is compared to a strain-based model, which predicts the deformation of RBCs in the VAD. For both models an Eulerian approach is used. In this study, new parameters are determined for the power law of the strain-based model. Hereby, the power law is fitted to data of experiments performed at the University of Maryland, Baltimore.

Results

As an example, blood damage in a benchmark blood pump of the U.S. Food and Drug Administration (FDA) is computed with a stress-based and a strain-based model using the new parameter set as well as parameter sets that were obtained in previous studies.

Conclusions

Critical locations in the pump, as identified with the stress-based and the strain-based model, differ significantly between the two models.

Authors: Lina Micaela , Mazza Roberto , Borreani Claudia , Brunelli Cinzia , Bianchi Elisabetta , Munarini Elena , Marco De Cinzia , Pozzi Paolo , Boffi Roberto
Published: April 2016

Purpose

Tobacco control guidelines recommend all healthcare professionals to ask patients about their smoking status and to offer them at least minimal cessation advice. However, few data are available about the daily practice of hospital clinicians who work with smoking cancer patients. This study assesses, in a comprehensive cancer center, the physicians’ smoking habit, their clinical practice in offering a smoking cessation intervention to patients who smoke, and the training they received in this field.

Methods

A Web-based survey was sent to 285 physicians.

Results

The survey response rate was 75%. Sixty-two percent, 24%, and 14% of responders were never, former, and current smokers, respectively. Six percent of all responding physicians have already participated in smoking cessation training and 43% of them declared their willingness to be trained. Eighty-six percent of all responding physicians asked about the patients’ smoking status, 50% routinely advised patients to quit smoking, and 32% assessed their motivation to do so. Smoking cessation guidelines were not followed mostly for lack of time, fear to increase patients’ stress, and lack of smoking cessation training. Ninety-four percent of responding physicians knew the smoking cessation service for outpatients and 65% referred at least one patient, 66% of responding physicians knew the service for inpatients, and 36% of them asked for at least one intervention in the ward.

Conclusions

This study pointed out partial adherence of the physicians working in a leading cancer center to the smoking cessation guidelines. The clinicians’ smoking habits did not influence the training and the clinical practice in offering patients smoking cessation interventions.
“Buried in an Herte”: French Poetics and the Ends of Genre in Chaucer's Complaint unto Pity
Authors: Rogers Cynthia A.
Published: April 2016

This article analyzes Chaucer's Complaint unto Pity in the light of the current renewed interest in form and English-French literary relations. It argues that a knowledge of medieval French poetic conventions reveals an interplay between form and meaning in Pity that would have been obvious in its original fourteenth-century bilingual Ricardian setting, but which is overlooked in modern readings. By exaggerating and twisting multiple components of the French love literature tradition, Chaucer creates a poem that is simultaneously both a clever critique and a loving homage of complaint.
“Seeking Truth in Detail”: “The Mystery of Marie Rogêt” and Its Structure of Revision
Authors: Booth Nathanael Thomas
Published: April 2016

“The Mystery of Marie Rogêt” has, since William Wimsatt's 1941 article “Poe and the Mystery of Mary Rogers,” enjoyed careful critical attention, most of it focusing on the ways the tale corresponds to or diverges from the historical events on which it is based. Poe revised the story in 1845. Most often, Poe's revisions are seen as an attempt to correct errors in his earlier version. This article will argue that, far from concealing Poe's earlier mistakes, Poe's revisions introduce discrepancies that cause the story to turn in on itself and to turn outward toward the reader. “Rogêt” is successful precisely because it is designed to call attention to its own falsity. Poe's alterations—and especially his initial footnote—invite the reader to apply Dupin's method and interrogate the text itself.
Seeing Is Believing: U.S. Imperial Culture and the Jerusalem Exhibit of 1904
Authors: Feldman Keith P.
Published: April 2016

What are the historical proximities and parallels linking Jews and Muslims in U.S. imperial culture? What are the technologies of knowledge production that make and make sense of these connections, and what are their effects? The Jerusalem Exhibit at 1904’s Louisiana Purchase Exposition in St. Louis offers a generative site through which to consider these questions. The exhibit included hundreds of “native” Muslim, Christian, and Jewish inhabitants, and exemplified a national covenantalism at the interface of U.S. settler colonialism and imperial rule. Visuality played a key role in staging and naturalizing racial difference between and among these various “natives,” even as its will towards transparency was routinely thwarted. While such overdetermined pedagogical labor never satisfied the predilections of American imperial authority, by the end of the exhibit’s run, it also served as an impetus to express political Zionism’s desires for Jewish nation-state status commensurate with other political formations organizing the World’s Fair.
Osteoporosis: An under-recognized public health problem
Authors: Vijayakumar Rajasree , Büsselberg Dietrich
Published: April 2016

Over 200 million people suffer from osteoporosis worldwide, which occurs when bone tissues become structurally deteriorated and bone mass becomes fragile, resulting in an increased risk of fracture. This review aims to describe the underlying risk factors and provide guidance on changes in lifestyle for those at risk of developing osteoporosis. It highlights risk factors such as age, sex, genetic background, and other under lying illnesses (factors that are generally “non-modifiable”). Furthermore, it focuses on factors that are dependent on lifestyle and (local) habits (factors that are “modifiable”), such as diet, sunlight exposure, exercise, and medication. Clearly, osteoporosis is a multifactorial disease and multiple of these risk factors can occur simultaneously. Currently, the data available differ greatly between regions and some areas might be affected more seriously than others. This review suggests that this might be due to differing healthcare training systems and suboptimal awareness of osteoporosis. Importantly, osteoporosis and resulting bone fractures represent a significant economic burden for both individuals and the wider society. Therefore, improved awareness of the disease may influence personal habits, reduce suffering, and alleviate the burden on healthcare expenditure.
What Guides Moral Consideration? Wittgenstein and Diamond on Imagination and Animal Ethics
Authors: Balaska Maria
Published: April 2016

I draw on the work of Ludwig Wittgenstein and Cora Diamond to argue that imagination plays a key role in moral consideration. By broadening our concepts and drawing similarities (Wittgenstein), our imagination can help us see nonhuman beings as fellow beings (Diamond), namely as beings with whom we share a life. I address two related issues: First, how can we ensure that the exercise of imagination does not merely lead to nonsense? Second, can the imagination remedy the supposed incommensurability between beings with linguistic capacity and those without? An examination of these issues can allow for a conceptual refinement of imagination.
Animals and Climate Change
Authors: Thornes Tobias
Published: April 2016

Climate change represents an unprecedented threat to animal life on Earth, brought about by a single species: humanity. It is well-known that humans will suffer greatly as a result of continued climate change over the coming decades and centuries, but the calamitous effects on other animals are often downplayed. Here, the origins and potential scope of climate change are explored and the implications for the whole animal kingdom are summarized. It is argued that humans, as part of this kingdom, have both a responsibility and an imperative to take immediate steps to avert climate change for the sake of all animal life.
Swinging for the State Department: American Women Tennis Players in Diplomatic Goodwill Tours, 1941-59
Authors: Brown Ashley
Published: April 2016

Cold War scholarship presents women’s importance to American propaganda and cultural diplomacy programs as limited to their roles as wives and mothers on the home front. This paper argues that female tennis players who served as goodwill ambassadors for the State Department represented public and vigorous aspects of American women’s lives outside the realm of domesticity. Cold War goodwill tours were based on barnstorming exhibition journeys made by the popular and influential Alice Marble during World War II. Doris Hart and Althea Gibson, both of whom battled adversity–physical disability and racial discrimination, respectively–led a cadre of highly skilled and accomplished women amateurs on global tours in the 1950s. These sportive peregrinations enabled players to enhance their skills, travel the world, and vie for titles while serving their country. Still, players were subject to the gendered and racialized politics, pressures, and restrictions faced by American women at large.
Southern Exposure: Life in the Carolina League in the Time of Jim Crow
Authors: Gmelch George
Published: April 2016

This essay describes the encounter of a white, minor-league ballplayer, now an anthropologist, with segregation in the American South in the 1960s. As an autoethnography, it examines what Jim Crow practices meant for young professional baseball players, both black and white. It treats how the author came to the research topic and the consequences for himself and his career in writing a newspaper feature in 1967 about Jim Crow in the North Carolina town he played for, in which he accused the local police chief of being a member of the Ku Klux Klan.
Racing Culture, Betting, and Sporting Protomodernity: The 1750 Newmarket Carriage Match
Authors: Huggins Mike
Published: April 2016

This paper offers a microstudy, deconstructing the meaning and significance of a famous carriage (or chaise) match at Newmarket in 1750 and a contemporary painting of the event. It uses these as a starting point to explore its relationship to debates about the early modern period and modernity. It analyzes the details of the carriage match, exploring its visual and print representations and its cultural context. It further argues that, for many sports at this time, the development of more formal regulations was driven by gambling and that gambling’s centrality needs to be recognized better. It then analyzes the event’s relationship to modernity issues such as scientific rationality, quantification, record keeping, and emerging bureaucratization. Finally, the essay shows how, rather than being mere servants or grooms, at least some of those involved were able to achieve high levels of wealth and status. This suggests that mid-eighteenth- century England had already moved toward further modernity in sports such as racing than has been assumed.
Doby Does It! Larry Doby, Race, and American Democracy in Post-World War II America
Authors: Moore Louis
Published: April 2016

"For Larry Doby," sportswriter Cleveland Jackson wrote, "it took but a few short minutes to walk up to that plate. But for 13 million American Negroes that simple action was the successful climax of a long uphill fight whose annals are like the saga of the race." Like Jackie Robinson, who integrated baseball three months prior with the Brooklyn Dodgers, Doby, the first African American player in the American League, gave black Americans optimism that individual talent could trump racism. But, unlike Robinson, Doby failed in his debut. His struggles struck up a conversation about race and democracy. Was economic integration about tokenism or talent? Merit or minstrelsy? Reverse racism or affirmative action? Would black workers unfairly take away work from white men? After a year of hard work and humility, however, Doby succeeded. For both races in Cleveland, he became a symbol for American democracy and opportunity. In the end, Doby’s first year in the big leagues is a story about white patience, black work ethic, and racial redemption.
A Black Fly in White Milk: The 1999 Women’s World Cup, Briana Scurry, and the Politics of Inclusion
Authors: Narcotta-Welp Eileen
Published: April 2016

Briana Scurry’s world-class save in the penalty shootout of the 1999 Fédération Internationale de Football Association (FIFA) Women’s World Cup provided the opportunity for the U.S. women’s national team to win their second World Cup championship. However, Scurry’s exceptional athletic feat was scarcely noted, as media outlets were more inclined to select images of Brandi Chastain’s emotional celebration. Situated in a particular historical neoliberal context characterized by postfeminist and postracial politics, Scurry’s mediated representation served to market this team to a global audience. I use a critical and oppositional reading of major U.S. sport magazines, daily U.S. national newspapers, and Nike advertisements to uncover and foreground decentered and obscured narratives. This analysis reveals the selective and strategic ways Scurry’s blackness and femininity were made to matter (and not matter) in order for a neoliberal, white, middle-class America to appear as an open, inclusive, and color-blind society while limiting Scurry to a precarious and restricted space within this American imaginary.
The Sabar Ways of Knowing Through the Arts
Authors: Sinha Pallawi , Hickman Richard
Published: April 2016

We engage with the significance of aesthetic experience as it is created and conferred in the everyday lives of everyday peoples, in this case, the indigenous Sabar tribes of Jharkhand, India. Through several months of fieldwork, we found that arts and aesthetic practices are integral to Sabar "ways of knowing, being, and doing." We examine definitions and identify limitations before introducing the social actors of the study. We illustrate how the arts empower "voice" by enabling multimodal expressions and access to data that other methods may not elicit. This paper offers discussions on how aesthetic experiences and activities are essential means of being; furthermore, it highlights the relevance of everyday aesthetics for the development of sustainable educational systems and future citizenship.
The Leisure Behavior of the Turkish Prospective Teachers
Authors: Aslan Nese , Arslan Cansever Belgin
Published: April 2016

This study focused on prospective teachers’ leisure behaviors. For this purpose, 47 fourth grade undergraduate students in Faculty of Education in Ege University, Izmir, Turkey participated. A qualitative research design was used in the study. In the process of analysing the data, Greimas’Actant Model as one of the analysing models in Semiology was utilized. This model has been used for the first time in Turkey as an analytical tool applied in leisure literature. It is based on the logical relationships to disaggregate an action into six Actant components. The interview technique assessed the individuals. Miles and Huberman’s measurements were used for reliability and validity, and the conformity was found to be 89%. The results of this research study (1) suggest a primary leisure participation in Turkey within the traditional norms and values of society, and (2) within it, the traditional differentiating role for gender.

Published: April 2016

Anther culture technique offers great opportunities to accelerate breeding progress. The current study aimed to develop some good doubled haploid lines (DH) through anther culture technique and to evaluate them along with their five parents including two check varieties for yield and yield related traits. Analysis of variance revealed that varietal differences were signified and wide variability present among the genotypes with respect to all the characteristics studied. Correlation analysis revealed that grain yield was highly positive correlated with panicle length. The information on the inter association among the yield attributing characters showed the nature and extent of relationship with each other. Consequently, this will help in the improvement of different characters along with yield in breeding programmes.

Climate and Phenology: Behavior of Autochthonous Italian Grapevine Varieties in the Uplands of Southern Brazil
Authors: Malinovski Luciane Isabel , Vieira Hamilton Justino , Camargo Campos Claudia Guimarães , Stefanini Marco , Silva Aparecido Lima da
Published: April 2016

The present study aimed to characterize the mesoclimate of the municipality of Água Doce, Brazil, and its influence on the phenological development and thermal requirements of autochthonous Italian varieties (Vitis vinifera L). The climate data were provided by a local automatic weather station. The principal phenological stages of red varieties (Aglianico, Ancellotta, Lambrusco, Malvasia Nera, Negroamaro, Nero d’Avola, Primitivo, Sangiovese, and Rebo) and white varieties (Fiano, Garganega and Vermentino) are analyzed. Results show that the mean temperature measured during the phenological cycles from September to April were higher than the climatological average (1961 to 2012). According to the Winkler, Huglin, and Cool Night bioclimatic indexes, the region is classified as “Region II”, cold and with cool nights, respectively. The average heat summation for the phenological cycles of the varieties was 1740 GDD (205 days, 2009-2010), 1463 GDD (187 days, 2010-2011), and 1408 GDD (176 days, 2011-2012). The Lambrusco variety presented the longest phenological cycle (203 days), while Garganega presented the shortest one (178 days). The lower temperatures of Água Doce, when compared to those in other regions where the varieties are traditionally produced, determine longer growing cycles and a shift in the timing of the phenological stages.
A Struggle for the Soviet Future: The Birth of Scientific Forecasting in the Soviet Union
Authors: Rindzevičiūtė Eglė
Published: April 2016

This article analyzes the development of Soviet scientific future studies after World War II, arguing that the field's theory and methods undermined the certainty of the communist future and laid the foundations for a new Soviet governmentality that acknowledged the intrinsic uncertainty of future development. The emphasis on uncertainty—but also the need for more data that could freely circulate between different branches of government and hence more transparency (glasnost')—called for radical revisions to Soviet notions of effective governance. Whereas some used future studies to criticize the actual practices of Soviet economic planning, others used this new type of expertise to extend personal influence and accumulate organizational power. Both cases, however, made it clear that Soviet governance had to accommodate the shift toward new constellations of power/knowledge in which scientific experts would play an ever-increasing role in shaping policy with regard to a fundamentally uncertain future.
Parahistory: History at Play in Russia and Beyond
Authors: Brooks Jeffrey , Dralyuk Boris
Published: April 2016

This essay examines a variety of popular engagements with history made possible by new technologies, namely the Internet and video games. We term these nondisciplinary appropriations of history parahistorical. Parahistory is an international phenomenon, but it is articulated differently in various national contexts. Russian parahistorical pursuits provide insight into both the phenomenon at large and the peculiarities of the Russian state's and population's attitudes toward history and historical memory. On the basis of a contextualized survey of Russian parahistory, we argue that historians cannot afford to ignore these uses of history beyond the academy which can teach us a great deal about the nature and broader implications of our discipline.

Assessing the New American Society of Clinical Oncology/College of American Pathologists Guidelines for HER2 Testing by Fluorescence In Situ Hybridization: Experience of an Academic Consultation Practice
Authors: Press Michael F. , Villalobos Ivonne , Santiago Angela , Guzman Roberta , Cervantes Monica , Gasparyan Armen , Campeau Anaamika , Ma Yanling , Tsao-Wei Denice D. , Groshen Susan
Published: April 2016

Context.—

Evaluation of HER2 gene amplification by fluorescence in situ hybridization (FISH) was changed by recent American Society of Clinical Oncology/College of American Pathologists (ASCO-CAP) guidelines.

Objective.—

To determine frequencies and assess patterns of HER2 protein expression for each ASCO-CAP guideline FISH category among 7526 breast cancers accrued to our consultation practice.

Design.—

We retrospectively reevaluated the HER2 FISH status of breast cancers in our consultation practice according to ASCO-CAP FISH guidelines, and documented HER2 protein levels in each category.

Results.—

—According to new guidelines, 17.7% of our consultation breast cancers were “ISH-positive” with HER2:CEP17 FISH ratios ≥2.0 and average HER2 gene copies per cell ≥4.0 (group 1); 0.4% were “ISH-positive” with ratios ≥2.0 and average copies <4.0 (group 2); 0.6% were “ISH-positive” with ratios <2.0 and average copies ≥6.0 (group 3); 4.6% were “ISH-equivocal” with ratios <2.0 and average copies ≥4.0 and <6.0 (group 4); and 76.7% were “ISH-negative” with ratios <2.0 and average copies <4.0 (group 5). However, only groups 1 (HER2 amplified) and 5 (HER2 not amplified) agreed with our previously reported status, and only these groups demonstrated the expected immunohistochemistry status, overexpression and low expression, respectively. Groups 2 and 4 breast cancers lacked overexpression, whereas group 3 was not significantly associated with either increased or decreased HER2 expression.

Conclusions.—

Although the status of approximately 95% of our cases (groups 1 and 5) is not affected by the new guidelines, those of the other 5% (groups 2–4) conflict with previous HER2 gene amplification status and with HER2 status by immunohistochemistry.

GaAs-based triangular barrier photodiodes with embedded type-II GaSb quantum dots
Authors: Vitushinskiy Pavel , Ohmori Masato , Kuroda Tomohiro , Noda Takeshi , Kawazu Takuya , Sakaki Hiroyuki
Published: April 2016

We fabricate GaAs-based triangular barrier photodiodes (TBPs), in which type-II GaSb quantum dots (QDs) are embedded in the vertex part of their triangular barriers. Their current–voltage characteristics and photo-responses are studied at low temperatures to show that GaSb QDs enhance the number and lifetime of photo-generated holes that are trapped by QDs in the barrier, resulting in the increase in the electron current around positively charged QDs. An extremely high responsivity of 109 A/W is achieved.
Analysis of phase noise in a spin torque oscillator stabilized by phase locked loop
Authors: Tamaru Shingo , Kubota Hitoshi , Yakushiji Kay , Fukushima Akio , Yuasa Shinji
Published: April 2016

This study analyses phase noise in a spin torque oscillator (STO) stabilized by phase locked loop (PLL). Time domain measurement showed that phase error of the 6.996 GHz signal generated by a STO, which exhibited a random-walk type fluctuation under free running, was suppressed within a standard deviation of 0.408 rad by the PLL. Power spectrum under phase locked oscillation indicated that the PLL had a loop bandwidth of approximately 16 MHz, thus effectively suppressing phase error below 10 MHz. However, it was also found that power spectrum of the residual phase error was distributed much higher than the loop bandwidth.
Magnetic field angle dependence of out-of-plane precession in spin torque oscillators having an in-plane magnetized free layer and a perpendicularly magnetized reference layer

Published: April 2016

Out-of-plane (OP) precession in spin torque oscillators having an in-plane (IP) magnetized free layer and a perpendicularly magnetized reference layer was studied. The bias voltage (V
B) and magnetic field angle (θ) dependence of the OP precession were investigated. The absolute values of the critical magnetic fields (

and

) between which OP precession is excited increased as V
B increased and as θ changed from the IP to the OP direction. The IP components of

converged to a constant value regardless of θ. This result indicates that excitation of OP precession is suppressed entirely by the IP component of the magnetic field, and the contribution of the OP component can be ignored. The experimentally observed precession behavior was successfully modeled by macrospin simulations.
Shot noise effect on noise source and noise parameter of 10-nm-scale quasi-ballistic n-/p-type MOS devices
Authors: Jeon Jongwook , Kang Myounggon
Published: April 2016

In this work, we investigated the noise source and noise parameters of a quasi-ballistic MOSFET at the high-frequency regime. We presented the shot noise properties in the measured drain current noise and its impact on the induced gate noise and the noise parameters of 10-nm-scale n-/p-type MOS (N/PMOS) devices for the first time. The measured noise sources and noise parameters were carefully analyzed with the shot and thermal noise models in all operation regions. On the basis of the results, new noise parameter models are proposed and the noise performance improvement in the quasi-ballistic regime is shown.

Three-dimensional (3D) InGaN/GaN quantum-well (QW) core–shell light emitting diodes (LEDs) are a promising candidate for the future solid state lighting. In this contribution, we study direct correlations of structural and optical properties of the core–shell LEDs using highly spatially-resolved cathodoluminescence spectroscopy (CL) in combination with scanning electron microscopy (SEM) and scanning transmission electron microscopy (STEM). Temperature-dependent resonant photoluminescence (PL) spectroscopy has been performed to understand recombination mechanisms and to estimate the internal quantum efficiency (IQE).
