Dynamic mode decomposition of numerical and experimental data

The description of coherent features of fluid flow is essential to our understanding of fluid-dynamical and transport processes. A method is introduced that is able to extract dynamic information from flow fields that are either generated by a (direct) numerical simulation or visualized/measured in a physical experiment. The extracted dynamic modes, which can be interpreted as a generalization of global stability modes, can be used to describe the underlying physical mechanisms captured in the data sequence or to project large-scale problems onto a dynamical system of significantly fewer degrees of freedom. The concentration on subdomains of the flow field where relevant dynamics is expected allows the dissection of a complex flow into regions of localized instability phenomena and further illustrates the flexibility of the method, as does the description of the dynamics within a spatial framework. Demonstrations of the method are presented consisting of a plane channel flow, flow over a two-dimensional cavity, wake flow behind a flexible membrane and a jet passing between two cylinders.
European Corn Borer: Pheromone Polymorphism or Sibling Species?

Electrophoretic analyses of the (Z) and (E) pheromone-attracted males of Ostrinia nubilalis (H�bner), the European corn borer, in an area of coexistence indicate that these strains are not freely interbreeding. Although the populations are morphologically indistinguishable, studies of allozyme, pheromone, and hybridization suggest that the (Z) and (E) entities are genetically differentiated, perhaps to the status of semi- or sibling species.
Regulation of simian virus 40 gene expression in Xenopus laevis oocytes

Expression of the simian virus 40 (SV40) early and late regions was examined in Xenopus laevis oocytes microinjected with viral DNA. In contrast to the situation in monkey cells, both late-strand-specific (L-strand) RNA and early-strand-specific (E-strand) RNA could be detected as early as 2 h after injection. At all time points tested thereafter, L-strand RNA was synthesized in excess over E-strand RNA. Significantly greater quantities of L-strand, relative to E-strand, RNA were detected over a 100-fold range of DNA concentrations injected. Analysis of the subcellular distribution of [35S]methionine-labeled viral proteins revealed that while the majority of the VP-1 and all detectable small t antigen were found in the oocyte cytoplasm, most of the large T antigen was located in the oocyte nucleus. The presence of the large T antigen in the nucleus led us to investigate whether this viral product influences the relative synthesis of late or early RNA in the oocyte as it does in infected monkey cells. Microinjection of either mutant C6 SV40 DNA, which encodes a large T antigen unable to bind specifically to viral regulatory sequences, or deleted viral DNA lacking part of the large T antigen coding sequences yielded ratios of L-strand to E-strand RNA that were similar to those observed with wild-type SV40 DNA. Taken together, these observations suggest that the regulation of SV40 RNA synthesis in X. laevis oocytes occurs by a fundamentally different mechanism than that observed in infected monkey cells. This notion was further supported by the observation that the major 5' ends of L-strand RNA synthesized in oocytes were different from those detected in infected cells. Furthermore, only a subset of those L-strand RNAs were polyadenylated.
Digital Dance Literacy: an integrated dance technology curriculum pilot project 1

Although the technological methods in which dance artists create, develop, document and present their work have grown significantly over the past two decades, technology education in undergraduate dance curricula in the US often remains peripheral. Some dance programs in higher education, especially those with graduate programs, now include a general course in dance technology that often functions as an overview of documentation methods and basic dance production. Given the technological advances and their creative applications in dance over the past decade (computer‐mediated choreography, musical scores, and sound environments; interdisciplinary and mixed media; Internet2 live telematic rehearsal and performance), this curriculum development project sought to design and implement a comprehensive technology curriculum for undergraduate dance students in bachelors degree programs in the US. Four developmental design problems were confronted in this pilot project, including how to provide: (1) integrated delivery of technology in required, rather than elective dance coursework, throughout four‐year undergraduate degree programs; (2) student‐centred design and relevance, capitalising on students’ own technology capital and interest; (3) balanced content in both creative application, as well as practical technological aspects; and (4) completion of digital e‐portfolio in the undergraduate senior year. From these guiding research problems, the Digital Dance Literacy (DDL) pilot program at Wayne State University seeks to produce a comprehensive, user‐friendly curriculum for integrating advanced technologies into undergraduate dance curricula. This paper gives an overview of this project’s development and implementation, description and content of the DDL curriculum and coursework, the project’s current status, as well as student, faculty and administrative perspectives. Additional problems in the research and development are also discussed.
Effects of Charismatic Content and Delivery on Follower Task Performance

The current study examined the moderating effect of task type on the effectiveness of charismatic leadership. Using a laboratory study, the content (visionary, nonvisionary) and delivery (expressive, unexpressive) of a leadership speech were manipulated, along with the charisma conduciveness of performance tasks. Based on the propositions asserted by Shamir and Howell, the authors suggest that charisma-conducive tasks are low in analyzability (more complex) and require greater levels of initiative and creativity. In addition, the authors expected that the effects of charismatic leadership on task performance should be more pronounced in terms of quality than quantity of performance. As expected, visionary content and expressive delivery resulted in higher attributions of charismatic leadership. In addition, visionary content led to better quality of performance on more charisma-conducive tasks.
Probabilistic Joint Image Segmentation and Labeling

We present a joint image segmentation and labeling model (JSL) which, given a bag of figure-ground segment hypotheses extracted at multiple image locations and scales, constructs a joint probability distribution over both the compatible image interpretations (tilings or image segmentations) composed from those segments, and over their labeling into categories. The process of drawing samples from the joint distribution can be interpreted as first sampling tilings, modeled as maximal cliques, from a graph connecting spatially non-overlapping segments in the bag [1], followed by sampling labels for those segments, conditioned on the choice of a particular tiling. We learn the segmentation and labeling parameters jointly, based on Maximum Likelihood with a novel Incremental Saddle Point estimation procedure. The partition function over tilings and labelings is increasingly more accurately approximated by including incorrect configurations that a not-yet-competent model rates probable during learning. We show that the proposed methodology matches the current state of the art in the Stanford dataset [2], as well as in VOC2010, where 41.7% accuracy on the test set is achieved.
Impact of initial intervention on long-term neurological recovey after cardiac arrest: data from the Luxembourg "North Pole" cohort.

BACKGROUND Prognosis after cardiac arrest is variable and difficult to predict. Early prognostic markers would facilitate the care of these patients. AIMS Therefore, we evaluated the impact of initial interventions after resuscitation on neurological outcome at 6 months. MATERIAL AND METHODS We conducted a retrospective analysis of the patient charts from consecutive cardiac arrest patients admitted to our intensive care unit and treated with induced hypothermia. RESULTS Over a 3-year period, 90 patients were included in our study. Sixty-four percent of the patients had bystander cardio-pulmonary resuscitation. An automated external defibrillator (AED) was used in 19% of the patients and the mean time to first defibrillation was 11 +/- 8.9 minutes. Patients being resuscitated and defibrillated by bystanders did better than those who had CPR only and far better than those patients in whom no rescue measures where attempted at all (73% vs. 56% vs. 32% for good neurological outcome, respectively, p= 0.03). Witnessed cardiac arrest was more frequent in patients with a good outcome than in those who collapsed without a witness (91% vs 75%, p = 0.03). In 76% of the patients with good outcome, CPR was performed whereas only 52% benefited from these measures in the bad outcome group (p = 0.01). Although the use of an AED was not significantly different between good and bad outcome groups (26% vs. 11%, p = 0.06), time to first defibrillation was significantly lower in patients with good outcome (8.7 +/- 6.3 vs. 13.3 +/- 11.3 minutes, p = 0.05). In the 17 patients in whom an AED was used, 12 (71%) recovered without major sequelae whereas in the 73 cases where no AED was used, only 34 (47%) had a good outcome (p = 0.06). At 6 months follow-up, 46 (51%) survivors had a good outcome (cerebral performance category 1-2), 5 (6%) survived with severe neurological sequelae or stayed in coma and 39 (43%) died. CONCLUSIONS Our local data confirm that early interventions have a major impact on survival of cardiac arrest patients. Efforts should concentrate on delivering rapid and high quality CPR as well as early defibrillation by AED's to every patient in cardiac arrest. Besides large scale Basic life support training, the introduction of dispatcher assisted CPR and the implementation and use of public AED's could considerably help to improve outcome in these patients.
The Spitzer/IRAC view of black hole–bulge scaling relations

We present a mid-infrared investigation of the scaling relations between supermassive black hole masses (M BH ) and the structural parameters of the host spheroids in local galaxies. This work is based on 2D bulge-disc decompositions of Spitzer/IRAC 3.6 μm images of 57 galaxies with M BH estimates. We first verify the accuracy of our decomposition by examining the Fundamental Plane (FP) of spheroids at 3.6 μm. Our estimates of effective radii (R e ) and average surface brightnesses, combined with velocity dispersions from the literature, define a FP relation consistent with previous determinations but doubling the observed range in R e . None of our galaxies is an outlier of the FP, demonstrating the accuracy of our bulge-disc decomposition which also allows us to independently identify pseudo-bulges in our sample. We calibrate M/L at 3.6 μm by using the tight M dyn ―L bul relation (∼0.1 dex intrinsic dispersion) and find that no colour corrections are required to estimate the stellar mass. The 3.6 μm luminosity is thus the best tracer of stellar mass yet studied. We then explore the connection between M BH and bulge structural parameters (luminosity, mass, effective radius). We find tight correlations of M BH with both 3.6 μm bulge luminosity and dynamical mass (M BH /M dyn ∼ 1/1000), with intrinsic dispersions of ∼0.35 dex, similar to the M BH ―σ relation. Our results are consistent with previous determinations at shorter wavelengths. By using our calibrated M/L, we rescale M BH ―L bul to obtain the M BH ―M * relation, which can be used as the local reference for high-z studies which probe the cosmic evolution of M BH ―galaxy relations and where the stellar mass is inferred directly from luminosity measurements. The analysis of pseudo-bulges shows that four out of nine lie on the scaling relations within the observed scatter, while those with small M BH are significantly displaced. We explore the different origins for such behaviour while considering the possibility of nuclear morphological components not reproduced by our 2D decomposition.
Acute myelogenous leukemia in elderly patients not eligible for intensive chemotherapy: the dark side of the moon.

BACKGROUND Acute Myelogenous Leukemia (AML) is a common disease in people aged>60 years. About 50% of the patients are not eligible for aggressive chemotherapy (CT) and are only managed with conservative approaches. Results in this subset of patients have not been reported so far. PATIENTS AND METHODS We retrospectively evaluated 244 consecutive elderly AML patients (M/F 143/101, median age 72 years, range 60-90) diagnosed at our institution from January 1989 to December 1998 and not eligible for intensive CT. Eighty-nine patients (36.5%) had evolved from previous myelodysplasia (sAML). Fifty-three out of 192 (26.4%) patients with available bone marrow (BM) analysis had oligoblastic leukaemia (blasts<40% and WBC<15x10(9)/l). RESULTS Sixty-seven patients (27.5%) were managed with supportive treatment only. One hundred seventy-seven patients (72.5%), in order to control disease, received conservative CT, consisting of Hydroxyurea (HU) (127 patients, 71.7%), Cytarabine and 6-Thioguanine (39 patients, 22%) or low-dose cytarabine (11 patients, 6.3%). Median overall survival was 179 days (1-3278) with 50 patients (20.5%) surviving>12 months. Older age (>75 years), poor WHO PS (>2), lower PLT levels (<50x10(9)/l) and higher absolute peripheral blast count (>5x10(9)/l) showed a negative prognostic impact on survival in multivariate analysis. CONCLUSIONS Our data outline the great heterogeneity of elderly AML patients not eligible for intensive CT. A simple scoring system including easily evaluable parameters, which could distinguish subjects with different prognosis, is proposed. Moreover, randomized studies in order to establish best conservative approaches are warranted.
The association between rumination and negative affect: A review

A total of 100 experimental, cross-sectional and longitudinal studies on the association between rumination and negative affects are reviewed. Experimental and cross-sectional studies support a positive association between rumination and sadness-depression whereas longitudinal studies show more diverse results. Longitudinal studies sampling clinical populations and with treatment during the follow-up display more null results. Concerning the relation between rumination and other negative affects there is strongest evidence for a positive association between rumination and anxiety, but more studies are necessary to illuminate the relation between rumination and other negative affects. The functionality of rumination is discussed along with possible explanations for the associations between rumination and different negative affects. The need for further differentiation of rumination is highlighted in order to distinguish the concept from other types of repetitive, negative thoughts.
Deduction from Uncertain Premises

We investigate how the perceived uncertainty of a conditional affects a person's choice of conclusion. We use a novel procedure to introduce uncertainty by manipulating the conditional probability of the consequent given the antecedent. In Experiment 1, we show first that subjects reduce their choice of valid conclusions when a conditional is followed by an additional premise that makes the major premise uncertain. In this we replicate Byrne (1989). These subjects choose, instead, a qualified conclusion expressing uncertainty. If subjects are given a third statement that qualifies the likelihood of the additional premise, then the uncertainty of the conclusions they choose is systematically related to the suggested uncertainty. Experiment 2 confirms these observations in problems that omit the additional premise and qualify the first premise directly. Experiment 3 shows that the qualifying statement also affects the perceived probability of the consequent given the antecedent of the conditional. Experiment 4 investigates the effect of suggested uncertainty on the fallacies and shows that increases in uncertainty reduce the number of certain conclusions that are chosen while affirming the consequent but have no effect on denying the antecedent. We discuss our results in terms of rule theories and mental models and conclude that the latter give the most natural account of our results.

Behavioral screening in well-child care: validation of the Toddler Behavior Screening Inventory.

OBJECTIVE To provide additional normative and validity data on the TBSI, especially to examine differences in clinical and nonclinical samples. METHODS The sample included 312 nonclinical and 50 clinical mothers of toddlers. Clinical participants consisted of mothers of toddlers who had been referred for outpatient psychological services. Mothers completed the TBSI, a 40-item behavioral screening measure for children 12 to 41 months old. The measure assesses frequency in which the behaviors occur and whether the mothers perceived the behaviors as problematic. In addition to the TBSI, mothers also completed several measures of maternal distress and social support. RESULTS The findings support the reliability and validity of the TBSL. In addition, the study found that TBSI scores effectively discriminated clinical from nonclinical participants. CONCLUSIONS The TBSI is a promising behavioral screening instrument that can be easily incorporated into a medical practice.
Thyroid hormone preconditioning: Protection against ischemia‐reperfusion liver injury in the rat

Recently, we reported that oxidative stress due to 3,3′,5‐triiodothyronine (T3)‐induced calorigenesis up‐regulates the hepatic expression of mediators promoting cell protection. In this study, T3 administration in rats (single dose of 0.1 mg/kg intraperitoneally) induced significant depletion of reduced liver glutathione (GSH), with higher protein oxidation, O2 consumption, and Kupffer cell function (carbon phagocytosis and carbon‐induced O2 uptake). These changes occurred within a period of 36 hours of T3 treatment in animals showing normal liver histology and lack of alteration in serum AST and ALT levels. Partial hepatic ischemia‐reperfusion (IR) (1 h of ischemia via vascular clamping and 20 h reperfusion) led to 11‐fold and 42‐fold increases in serum AST and ALT levels, respectively, and significant changes in liver histology, with a 36% decrease in liver GSH content and a 133% increase in that of protein carbonyls. T3 administration in a time window of 48 hours was substantially protective against hepatic IR injury, with a net 60% and 90% reduction in liver GSH depletion and protein oxidation induced by IR, respectively. Liver IR led to decreased DNA binding of nuclear factor‐κB (NF‐κB) (54%) and signal transducer and activator of transcription 3 (STAT3) (53%) (electromobility shift assay), with 50% diminution in the protein expression of haptoglobin (Western blot), changes that were normalized by T3 preconditioning. Conclusion: T3 administration involving transient oxidative stress in the liver exerts significant protection against IR injury, a novel preconditioning maneuver that is associated with NF‐κB and STAT3 activation and acute‐phase response.

Race is elsewhere: state-socialist ideology and the racialisation of Vietnamese workers in Czechoslovakia

Current literature sees expressions of popular racism in twentieth-century European state-socialist societies either as directly deriving from the official ideology of the state or else as happening despite it. This article argues that the ways in which Vietnamese workers were racialised in 1980s Czechoslovakia were neither directly derived from the state’s official ideology, nor did they arise in opposition to that ideology. Instead, it suggests that they are more usefully seen as reworkings of certain elements of the state’s official ideology. Most important among those elements were: the insistence that racism did not exist in Czechoslovakia; the centrality of ‘honest socialist work’; and the conception of the overseas foreign workers programme as a socialist civilising mission of sorts. In most cases, some or all of these notions worked in tandem, and, moreover, also built upon existing discourses in regard to the Roma.
Perinatal Mortality Magnitude, Determinants and Causes in West Gojam: Population-Based Nested Case-Control Study

Introduction In Ethiopia, even if a significant reduction in child mortality is recorded recently, perinatal mortality rate is still very high. This study assessed the magnitude, determinants and causes of perinatal death in West Gojam zone, Ethiopia. Methods and materials A nested case control study was conducted on 102 cases (mothers who lost their newborns for perinatal death) and 204 controls (mothers who had live infants in the same year) among a cohort of 4097 pregnant mothers in three districts of the West Gojam zone, from Feb 2011 to Mar 2012. Logistic regression models were used to identify the independent determinant factors for perinatal mortality. The World Health Organization verbal autopsy instrument for neonatal death was used to collect mortality data and cause of death was assigned by a pediatrician and a neonatologist. Result Perinatal mortality rate was 25.1(95% CI 20.3, 29.9) per 1000 live and stillbirths. Primiparous mothers had a higher risk of losing their newborn babies for perinatal death than mothers who gave birth to five or more children (AOR = 3.15, 95% CI 1.03–9.60). Babies who were born to women who had a previous history of losing their baby to perinatal death during their last pregnancy showed higher odds of perinatal death than their counterparts (AOR = 9.55, 95% CI 4.67–19.54). Preterm newborns were more at risk for perinatal death (AOR = 9.44, 95%CI 1.81–49.22) than term babies. Newborns who were born among a household of more than two had a lesser risk of dying during the perinatal period as compared to those who were born among a member of only two. Paradoxically, home delivery was found to protect against perinatal death (AOR = 0.07 95% CI, 0.02–0.24) in comparison to institutional delivery. Bacterial sepsis, birth asphyxia and obstructed labour were among the leading causes of perinatal death. Conclusion Perinatal mortality rate remains considerably high, but proper maternal and child health care services can significantly decrease the burden.
