Electrooptical Analysis of Effects Induced by Floating Metallic Interlayers in Organic LEDs

The aim of this paper is to investigate the electrical and optical property modifications that can be related to the presence of a nanometric metallic layer at the interface between two organic emissive materials in a stacked structure. For purposes of comparison, reference devices have also been analyzed to emphasize the increase of electrical switching and hysteresis behaviors in current-voltage plots and spectral variations in electroluminescence. In this paper, we have tried to summarize the electrical effects of the floating nanometric thin metallic layer by extracting a small number of parameters which can represent the current state of the device.
MR parameter quantification with magnetization‐prepared double echo steady‐state (MP‐DESS)

The mapping of MR relaxation times and proton density has been the subject of research in medical imaging for many years, as it offers the possibility for longitudinal investigation of disease and the correlation with related biochemical processes. The purpose of this study is to provide a fast mapping protocol, which simultaneously acquires MR relaxation times and relative proton density without compromising accuracy and precision.
Description of A New Capillariinae (Nematoda: Trichuridae) from Scapteromys aquaticus (Cricetidae: Sigmodontinae) from Buenos Aires, Argentina

Abstract: A new species of Capillaria is described on the basis of specimens recovered from the intestine of the swamp rat Scapteromys aquaticus (Cricetidae: Sigmodontinae) from Argentina. Capillaria alainchabaudi n. sp. and a peculiar species from Australian marsupials are the only 2 species of Capillaria sensu stricto parasitic in mammals. A comparison with the Australian species and with the 18 species of this genus described from other vertebrates from the Western Hemisphere is given. The separation of the new species is based on morphologic and morphometrical features, such as intestine ending in cloaca beside ejaculatory duct, 2 lateral nonmembranous caudal lobes, 2 pairs of caudal non-pedunculated papillae, terminal part of cylindrical cirrus ornamented with thin and thick spines, spicule with apex not well sclerotized in the males, a conspicuous vulvar appendage in the females, and 2 bacillary bands. A survey of the literature revealed that the species of Capillariinae from rodents belong to 9 genera, and the total number of species is low compared to the high diversity and abundance of the hosts, particularly if the modern Muroidea are considered.
Neuroendocrine responses to caffeine in the work environment.

&NA; The effect of caffeine on neuroendocrine stress responses in the workplace was studied in 14 habitual coffee drinkers. Urinary catecholamine and cortisol levels were measured on 2 study days, in a 4‐hour interval from morning until noon, while participants performed their normal work‐related activities. Caffeine (300 mg) or placebo was administered blind at the beginning of study intervals, after overnight caffeine abstinence. Retrospective mood and symptom ratings were collected at the end of each morning. Caffeine elevated urinary epinephrine levels during work by 37% but did not affect norepinephrine or cortisol levels. Subjective reports suggest that caffeine abstinence was associated with symptoms of caffeine withdrawal by the end of the morning. Effects included higher ratings of sleepiness, lethargy, and headache and a reduced desire to socialize. Results suggest caffeine may increase the activity of the sympathetic adrenal‐medullary system during everyday activities in the work environment. This action may potentiate psychophysiological responses elicited by occupational stressors.
TIVA, awareness, and the Brice interview.

To the Editor:Drs. Eger and Sonner (1) recently raised the question: is recall more likely during IV versus inhaled anesthesia? There is no proper answer, but some findings indicate that the answer is no, as using the most (only) used diagnostic instrument for awareness detection, the structured int
Towards a point-of-care strip test to diagnose sickle cell anemia

A rapid test to identify patients with sickle cell disease could have important benefits in low-resource settings. Sickle cell anemia (SCA) affects about 300,000 newborns each year, the majority of whom are born in sub-Saharan Africa. Low-cost therapies are available to treat SCA, but most countries in sub-Saharan Africa lack robust neonatal screening programs needed to identify patients in need of treatment. To address this need, we developed and evaluated a competitive lateral flow assay that identifies patients with SCA (genotype HbSS) in 15 minutes using undiluted whole blood. A small volume of blood (0.5 μL– 3 μL) is mixed with antibody-coated blue latex beads in a tube and applied to the strip. Strips are then placed in a well of running buffer and allowed to run for 10 minutes. Laboratory evaluation with samples containing different proportions of hemoglobin A (HbA) and hemoglobin S (HbS) indicated that the test should enable identification of SCA patients but not persons with sickle cell trait (SCT). We evaluated the test using 41 samples from individuals with SCA, SCT, and normal blood. With visual inspection or quantitative analysis, we found a 98% accuracy when differentiating SCA from normal and SCT samples as a group (90% sensitivity and 100% specificity for identifying SCA). This work demonstrates important steps towards making a lateral flow test for hemoglobinopathies more appropriate for point-of-care use; further work is needed before the test is appropriate for clinical use.
Mentale Rotation bei Vorschulkindern: Geschlechtsunterschiede in der Lateralisierung

Die Mentale Rotation gehort zu der Kategorie von raumlich kognitiven Aufgaben, bei denen immer wieder grose Geschlechtsunterschiede zugunsten von Mannern gefunden wurden und die zudem durch Unterschiede in der hemispharischen Asymmetrie zwischen den Geschlechtern gekennzeichnet sind (z.B. Hugdahl, Thomsen, & Ersland, 2006). Obwohl vor etwa einem Jahrzehnt die Uberlegenheit des mannlichen Geschlechts bereits im Alter von etwa viereinhalb Jahren nachgewiesen werden konnte (Levine, Huttenlocher, Taylor, & Langrock, 1999), existierten bis heute keine Erkenntnisse daruber, ob die beobachteten Leistungsunterschiede bei Kindern auch von Unterschieden in der Lateralisierung begleitet werden. Eine weitere Frage, die in diesem Zusammenhang bisher unbeantwortet geblieben ist, ist die nach der Ursache der Geschlechtsunterschiede. Hier kommen sowohl biologische als auch soziale Erklarungsansatze in Betracht. Gerade in der jungeren Vergangenheit wurden hormonelle Einflussfaktoren als ursachlich diskutiert, da gezeigt werden konnte, dass sich die Lateralisierung bei Frauen im Verlauf des Menstruationszyklusses verandert (z.B. Hausmann & Bayer, 2009). Die vorliegende Arbeit hat sich speziell mit den elektrophysiologischen Korrelaten mentaler Rotation bei Kindern befasst. In einer ersten Untersuchung wurde zunachst uberpruft, ob sich die in Studien mit Erwachsenen gezeigten Lateralisierungs-unterschiede bereits im Vorschulalter finden lassen. Es zeigten sich einerseits, wie erwartet, bessere Leistungen der Jungen hinsichtlich der Fehlerrate und andererseits Unterschiede in der Lateralisierung zwischen den Geschlechtern. Wahrend der mentalen Rotation wurde bei Jungen eine bilaterale Hirnaktivitat beobachtet, Madchen zeigten hingegen eine deutliche linkshemispharische Aktivitat. Die Frage, ob sich die gefundenen Lateralisierungsunterschiede auch mit fur diese Altersgruppe schwierigerem Stimulusmaterial replizieren lassen, wurde in einer zweiten Studie untersucht. In dieser wurden Buchstaben anstatt Tierzeichnungen als Stimulusmaterial verwendet. Hinsichtlich der Leistung unterschieden sich Madchen und Jungen nicht voneinander, die bereits in der ersten Studie gefundenen Unterschiede in Bezug auf die Hirnaktivitat zeigten sich jedoch auch in dieser Untersuchung. Wahrend hinsichtlich der rechten Hemisphare keine Aktivierungsdifferenzen zwischen den Geschlechtern festgestellt werden konnten, zeigten sich linksseitig deutliche Unterschiede. Folglich sind fur Geschlechtsunterschiede in Bezug auf die Hirnaktivitat nicht diejenigen hormonellen Veranderungen erforderlich, die erst mit Beginn der Pubertat auftreten. Diese Ergebnisse konnen als weitere Evidenz fur einen essentiellen Anteil biologisch-neuronaler Faktoren an den Geschlechtsunterschieden betrachtet werden.
A sensor interface based on sparse NMF for piano musical transcription

A new sensor interface for detecting notes in the musical audio signals is proposed. Our sensor interface is able to transform acoustic pressure, caused by a sound wave of polyphonic piano music, into a musical score, that is a symbolic representation of musical notes. We focuses on note attack instant (onset) and note name (pitch). Signal processing techniques based on the Constant-Q Transform (CQT) are used to create a time-frequency representation of the signal. In particular, we propose a supervised classification methods based on sparse Non-Negative Matrix Factorization (NMF) to detect note pitch. We present a collection of experiments using the Inventions and Sinfonias BWV 772–801 of the composer J. S. Bach.
Chemical-microstructural-nanomechanical variations in the structural units of the cuttlebone of Sepia officinalis

‘Cuttlebone’, the internalized shell found in all members of the cephalopod family Sepiidae, is a sophisticated buoyancy device combining high porosity with considerable strength. Using a complementary suite of characterization tools, we identified significant structural, chemical and mechanical variations across the different structural units of the cuttlebone: the dorsal shield consists of two stiff and hard layers with prismatic mineral organization which encapsulate a more ductile and compliant layer with a lamellar structure, enriched with organic matter. A similar organization is found in the lamellar matrix, which consists of individual chambers separated by septa, and supported by meandering plates (‘pillars’). Like the dorsal shield, septa contain two layers with lamellar and prismatic organization, respectively, which differ significantly in their mechanical properties: layers with prismatic organization are a factor of three stiffer, and up to a factor of ten harder than those with lamellar organization. The combination of stiff and hard, and compliant and ductile components may serve to reduce the risk of catastrophic failure, and reflect the role of organic matter for the growth process of the cuttlebone. Mechanically ‘weaker’ units may function as sacrificial structures, ensuring a step-wise failure of the individual chambers in cases of overloading, allowing the animals to retain near-neutral buoyancy even with partially damaged cuttlebones. Our findings have implications for the structure-property-function relationship of cuttlebone, and may help to identify novel bioinspired design strategies for light-weight yet high-strength foams.
Barriers to Diabetes Self-Management Among Rural Individuals in the Workplace

Higher rates of type 2 diabetes mellitus (T2DM) are found in rural populations and barriers lessen the ability of these individuals to effectively manage diabetes. By lessening potential barriers to self-care management, health professionals, especially occupational health nurses, can assist individuals confidently manage T2DM. In this article, the authors provide an overview of diabetes self-management barriers for rural populations and implications for health professionals who assist individuals with T2DM in the workplace.
Prospective study of a self-report type A scale and risk of coronary heart disease: test of the MMPI-2 type A scale.

To the Editor: Kawachi et al1 report that type A behavior, as measured by the Minnesota Multiphasic Personality Inventory (revised) (MMPI-2), is an independent predictor of coronary heart disease death, nonfatal myocardial infarction, and angina, even after controlling for anger and cynicism, also measured by the MMPI-2. This is the first study to validate the predictive validity of the MMPI-2 for cardiac end points. The risk ratios observed were moderately strong, although not as strong as those previously observed for other measures of emotional distress (eg, the Beck Depression Inventory and the Crown-Crisp Phobic Anxiety Inventory). Because …
Extrafollicular Activation of Lymph Node B Cells by Antigen-Bearing Dendritic Cells

In contrast to naïve T cells that recognize short antigen-derived peptides displayed by specialized antigen-presenting cells, immunoglobulin receptors of B lymphocytes primarily recognize intact proteins. How and where within a lymph node such unprocessed antigens become available for naïve B cell recognition is not clear. We used two-photon intravital imaging to show that, after exiting high-endothelial venules and before entry into lymph node follicles, B cells survey locally concentrated dendritic cells. Engagement of the B cell receptor by the dendritic cell (DC)–associated antigen leads to lymphocyte calcium signaling, migration arrest, antigen acquisition, and extrafollicular accumulation. These findings suggest a possible role for antigen-specific B-DC interactions in promoting T cell–dependent antibody responses in vivo.
Current opinion on drug-induced oral reactions: a comprehensive review.

AIM The aim of this comprehensive review is to present an update to our previous review about drug-induced oral reactions. All drugs that may cause adverse effects in the mouth and related structures are reviewed. BACKGROUND Every drug can produce untoward consequences even when used according to standard or recommended methods of administration. Adverse drug reactions can involve every organ and system of the body and are frequently mistaken for signs of underlying disease. The mouth and associated structures can also be affected by many drugs or chemicals. Good oral health including salivary function is very important in maintaining whole body health. Drug reactions can be categorized as to the parts of the oral complex such as the oral mucosa and tongue, periodontal tissues, dental structures, salivary glands, cleft lip and palate, muscles, and nerves. REVIEW RESULTS This review suggests the number of drugs and chemicals that can produce adverse or toxic reactions in the oral cavity are on the rise. An updated listing of offending drugs is provided along with current strategies for dealing with adverse reactions. CONCLUSION Clinicians must constantly update their knowledge of drugs used by their patients. Attention must be paid to their toxic and unwanted effects that in many cases may be similar to characteristics of common diseases. CLINICAL SIGNIFICANCE Dentists and specialists of oral diseases should be aware of adverse drug oral reactions for better diagnosis of oral diseases, administration of drugs, and patient compliance during drug therapy.
Reducing the Impact of EV Charging Operations on the Distribution Network

A key assumption made in this paper is that electric vehicle (EV) battery charging profiles are rectangular. This requires a specific and new formulation of the charging problem, involving discrete action sets for the EVs in particular. The considered cost function comprises of three components: 1) the distribution transformer aging; 2) the distribution energy losses; and 3) a component inherent to the EV itself (e.g., the battery charging monetary cost). Charging start times are determined by the proposed distributed algorithm, whose analysis is conducted by using game-theoretic tools such as ordinal potential games. Convergence of the proposed algorithm is shown to be guaranteed for some important special cases. Remarkably, the performance loss with respect to the centralized solution is shown to be small. Simulations, based on realistic public data, allow one to gain further insights on the issues of convergence and optimality loss, and provide clear messages about the tradeoff associated with the presence of the three components in the considered cost function. While simulations show that the proposed charging policy performs quite similarly to existing (continuous) charging policies such as valley-filling-type solutions when the non-EV demand forecast is perfect, they reveal an additional asset of rectangular profiles in presence of forecasting errors.

Analysis of intervehicle communication

In this paper, we integrate key wireless propagation effects such as the path loss, shadowing, and multipath fading into a single Fox's H-variate using the H-preserving property under products, powers, quotients, and their combinations. We then establish a unifying framework to analyze the error probability and channel capacity for V2V communication in a Cox field of vehicles, using again the language of Fox's H-functions. This framework enables us to characterize intervehicle communication in the doubly stochastic vehicular ad-hoc network (VANET) by averaging both small- and large-scale fading processes in time and (random) distance-dependent path losses in space.

Analysis of Fingerprint Image Enhancement using Gabor Filtering with Different Orientation Field Values

Fingerprint image enhancement is the key process in IAFIS systems. In order to reduce false identification ratio and to supply good fingerprint images to IAFIS systems for exact identification, fingerprint images are generally enhanced. A filtering process tries to filter out the noise from the input image, and emphasize on low, high and directional spatial frequency components of an image. This paper presents an experimental summary of enhancing fingerprint images using Gabor filters. Frequency, width and window domain filter ranges are fixed. The orientation angle alone is modified by 0 radians, , and radians. The experimental results show that Gabor filter enhances the fingerprint image in a better way than other filtering methods and extracts features.

Interrater Reliability of Clinical Ratings and Neurocognitive Diagnoses in HIV

We examined the interrater reliability (IRR) of clinical ratings of neuropsychological (NP) impairment and neurocognitive diagnoses in HIV. Thirty participants with advanced HIV-infection who were enrolled in a multicenter HIV brain banking research project underwent comprehensive NP and neuromedical evaluations. Using a standardized system of guidelines, neuropsychologists from six participating sites independently assigned clinical ratings of NP impairment, as well as multilevel diagnoses reflecting the inferred etiology of the impairments and their effects on everyday functioning. Findings indicated excellent IRR in rating the presence and severity of NP impairment, but overall modest IRR for neurocognitive diagnoses. Not surprisingly, most diagnostic disagreements concerned the etiology of impairments in persons with medical and neuropsychiatric risk factors in addition to HIV.
Nanoscale Phase Evolution during Continuum Decomposition of Fe-Cr Alloys

The continuum decomposition of the Fe-Cr alloys from initial phase separation to steady-state coarsening with concentrations varying from 25 at % Cr and 30 at % Cr to 33 at % Cr aged at 750 K was studied by utilizing three-dimensional phase-field simulations. The dynamic stages of separation of nanoscale Cr-enriched α′ phase were distinguished by the evolution of the volume fraction, particle number density and the average particle radius of the α′ phase. The stage of steady-state coarsening was characterized with an equilibrium volume fraction and decreasing particle number density. The coarsening rate constant by linear fitting of the cube of average radius and aging time shows an increase with the increasing Cr concentration. The time exponents decrease from the growth and coarsening stage to the steady-state coarsening stage and show a dependence on the particles number density at different concentrations. The quantitative evolutions of α′ phase via nucleation growth and spinodal decomposition are theoretically helpful for understanding the microstructure evolution with aging time in Fe-Cr alloys.
