Engagement and skill development through an innovative classroom music program

Rates of music participation are low in developed nations. This may be attributed in part to the failure of school music to engage children sufficiently to motivate them to continue learning and participating in music. We tested the Harmonix program of classroom music education, which is currently being designed to maximize engagement in music learning. The program employs a set of new, harmonically tuned percussion instruments, using cyclical, self-cuing patterns, and hierarchical rhythmic structures that match complexity with ability. Graphical scores reduce cognitive load, and assist students to compose music from the first class. Cooperative learning activities consolidate learning and further stimulate engagement through personal and group expression. Using a combination of timely self-report and objective measurement, we found that student learning and skill acquisition increased over the six-week program while high engagement was maintained. Engagement measures also increased within each session. Over the six weeks of the program no significant changes were observed in attitudes toward music.
System Modeling in the COSMA Environment

The aim of this paper is to demonstrate how the COSMA environment can be used for system modeling. This environment is a set of tools based on Concurrent State Machines paradigm and is developed in the Institute of Computer Science at the Warsaw University of Technology. Our demonstration example is a distributed brake control system dedicated for a railway transport. The paper shortly introduces COSMA. Next it shows how the example model can be validated by our temporal logic analyzer.
iVA-File: Efficiently Indexing Sparse Wide Tables in Community Systems

In community web management systems (CWMS), storage structures inspired by universal tables are being used increasingly to manage sparse datasets. Such a sparse wide table (SWT) typically embodies thousands of attributes, with many of them being undefined in each tuple, and low-dimensional structured similarity search on a combination of numerical and text attributes is a common operation. However, many properties of such wide tables and their associated Web 2.0 services render most multi-dimensional indexing structures irrelevant. Recent studies in this area have mainly focused on improving the storage efficiency and efficient deployment of inverted indices; so far no new index has been proposed for indexing SWTs. The inverted index is fast for scanning but not efficient in reducing random accesses to the data file as it captures little information about the content of attribute values. In this paper, we propose the iVA-file that works on the basis of approximate contents and keeps scanning efficiency within a bounded range. We introduce the nG-signature to approximately represent data strings and improve the existing approximate vectors for numerical values. We also propose an efficient query processing strategy for the iVA-file, which is different from strategies used for existing scan-based indices. To enable the use of different metrics of distance between a query and a tuple that may vary from application to application, the iVA-file has been designed to be metric-oblivious and to provide efficient filter-and-refine search based on any rational metric. Extensive experiments on real datasets show that the iVA-file outperforms existing proposals in query efficiency significantly, at the same time, keeps a good update speed.
Enhanced OSPF Graceful Restart

Modern OSPF (Open Shortest Path First) routers can preserve their packet forwarding activity while they reboot. This enables maintenance operations in the control plane with minimum impact on the data plane, such as the Graceful Restart (GR) procedure. This of course assumes the stability of the network topology, since a rebooting router is unable to adapt its forwarding table and may cause routing loops. The Graceful Restart standard thus recommends to revert to a normal OSPF restart as soon as a topological change is advertised. This paper proposes to be less conservative and to take full advantage of the separation between the control and forwarding functions. This is achieved by new specific functionalities: (a) the prediction of routing loops caused by a restarting router, (b) the determination of the minimal number of temporary backup forwarding actions that should be applied to prevent these loops, without reverting back to a normal OSPF restart, and (c) the design of action plans to set and remove these temporary backups in order to avoid micro-loops when the restarting router goes back to a normal functioning. This results in minimal traffic perturbations when topology changes during a maintenance operation. [1] provides a longer version of this paper, including proofs.
Expression of ob Gene in Adipose Cells

The product of the recently cloned mouse obese (ob) gene is likely to play an important role in a loop regulating the size of the adipose tissue mass. The hormonal regulation of the ob gene could affect adiposity. To investigate this point, the effect of insulin on ob gene expression was examined in cells of the 3T3-F442A preadipocyte clonal line. ob mRNA is absent from exponentially growing, undifferentiated cells as well as from confluent preadipose cells. Terminal differentiation of preadipose to adipose cells leads to the expression of ob mRNA detected by a sensitive and quantitative ribonuclease protection assay. In adipose cells, the level of ob mRNA is sensitive to insulin in the nanomolar range of concentrations with an increase from an average of 1 copy to 5-10 copies/cell. The effect of insulin was fully reversible and takes place primarily at a transcriptional level. The ob mRNA shows a rapid turnover, with a half-life of approximately 2 h in the absence or presence of insulin. The level of secreted Ob protein is also regulated by insulin. These results indicate that the ob gene is expressed in mature fat cells only and support the possibility that insulin is an important regulator of ob gene expression.
Effect of lavender essence inhalation on the level of anxiety and blood cortisol in candidates for open-heart surgery

Background: Surgery, as a treatment, is a stressful experience. The anxiety is more severe in open-heart surgery patients due to its risk and complications. The present study aimed to determine the effect of lavender essence on the levels of anxiety and blood cortisol in candidates for open-heart surgery. Materials and Methods: This was a single-blind clinical trial, a random allocation study with a control group conducted on 90 candidates for open-heart surgery in two groups of study and control. The study and control groups inhaled two drops of lavender and distilled water for 20 min, respectively. Spielberger questionnaire was filled by the patients. A 2 ml blood sample was taken to measure the cortisol level and patients′ vital signs were recorded before and after intervention. Data were analyzed by chi-square in the form of mean, SD, and frequency distribution, independent t-test, paired t-test, and analysis of covariance (ANCOVA), with a significance level of P = 0.05 to modify the pre-test scores. Results: Results showed a significant reduction in mean anxiety score from 56.73 (5.67) to 54.73 (5.42) after intervention in the study group, compared to the control group [1.11 (1.17)] (P < 0.001). There was also a higher difference in cortisol level in the study group compared to the control group [1.88 (0.56) vs. 0.42 (0.45)]. ANCOVA test showed that the 10.8% variance in anxiety score and 69.6% decrease in blood cortisol resulted from inhalation of lavender. Conclusions: Results showed the positive effect of lavender essence on anxiety and blood cortisol level among the patients. Aromatherapy with lavender is suggested to be considered as a nursing intervention in clinical settings.
Split Liver Transplantation

Liver transplantation is the most effective treatment for the patients with acute liver failure or end-stage liver diseases. Liver transplantation is also indicated for patients with hepatocellular carcinoma to yield a best result if the tumor/tumors meet Milan criteria, University of California San Francisco(UCSF) criteria, or up-to-seven criteria. It is no doubt that more and more people need liver transplantation to save their lives. However, liver donation is always short to match the demand of liver transplanta‐ tion. Therefore, how to expand the donor pool to increase the opportunities of liver transplantation is paramount. Splitting liver is one of the ways to expand the donor pool and offers an additional chance of liver transplantation. At the beginning of split liver transplantation (SLT), the liver was split and transplanted to an adult and a child. Now, the liver can be split into full right and left lobes and transplanted to two adults. When split liver transplantation is to be performed, there are many considerations that should be clarified. With the improvement of surgical skill, the outcomes of split liver transplantation are similar to that of deceased whole liver transplantation. It is worth to promote the policy of split liver transplantation.
Recommendation in Context-Rich Environment: An Information Network Analysis Approach

Recommendation has received tremendous attention recently due to its wide and successful applications across different domains. Different from traditional setting of recommendation tasks, modern recommendation tasks are usually exposed in a context-rich environment. For example, in addition to a user-item rating matrix, users and items are connected to other objects via different relationships and they are usually associated with rich attributes, such as text and spatio-temporal information. It turns out that heterogeneous information network serves a natural data model to capture the rich context of these recommendation tasks. In this tutorial, we will systematically introduce the methodologies of using heterogeneous information network mining approach to solve recommendation tasks, and demonstrate the effectiveness of such methods using different applications, ranging from collaboration recommendation in scientific research network to job recommendation in professional social network, and to drug discovery in biomedical networks. The topics to be covered in the tutorial include: (1) overall introduction; (2) recommendation in heterogeneous information networks, which introduces the general methodology of how to model the recommendation problem as a heterogeneous information network mining problem; (3) recommendation in a text-rich setting, where the information network is further enriched by refined analysis of text information; (4) recommendation with spatio-temporal information, where entities and relationships in the network are associated with spatio-temporal attributes; and (5) research frontiers for context-rich recommendation.
Characterizing Types of Readmission After Acute Coronary Syndrome Hospitalization: Implications for Quality Reporting

Background Thirty‐day readmission rates have been tied to hospital reimbursement in the United States, but remain controversial as measures of healthcare quality. We profile the timing, main diagnoses, and survival outcomes of inpatient and emergency department readmissions after acute coronary syndrome (ACS), based on a large regional database. Methods and Results Patients enrolled in the Alberta Provincial Project for Outcomes Assessment in Coronary Heart Disease (APPROACH) registry with an ACS hospitalization between April 2008 and March 2010 (n=3411) were included. Primary outcomes were inpatient and emergency department–only readmissions, at 30 days and 1 year. Predictors of 30‐day readmission were identified, and the association between 30‐day readmission status and mortality was evaluated. A total of 1170 (34.3%) patients had ≥1 hospital readmission within 30 days, reaching 2106 (61.7%) within 1 year of ACS discharge. Of first readmissions, 45% were emergency department only and 53% were for cardiovascular or possibly related diagnoses. Renal disease and diabetes predicted all‐cause readmissions at 30 days and 1 year, but there were no robust predictors of cardiovascular readmissions. Thirty‐day inpatient, but not emergency department, readmissions were associated with increased mortality. Conclusions Hospital readmissions within 30 days after discharge for ACS are common, and associated with increased mortality. However, our findings underline that readmissions are quite heterogeneous in nature, and that many readmissions are unrelated to index stay and thus not easily predicted with common clinical variables. All‐cause 30‐day readmission rates may be too simplistic, and perhaps even misleading, as a hospital performance metric.
Multidimensional Scaling Localization Algorithm in Wireless Sensor Networks

Due to the localization algorithm in large-scale wireless sensor network exists shortcomings both in positioning accuracy and time complexity compared to traditional localization algorithm, this paper presents a fast multidimensional scaling location algorithm. By positioning algorithm for fast multidimensional scaling, fast mapping initialization, fast mapping and coordinate transform can get schematic coordinates of node, coordinates Initialize of MDS algorithm, an accurate estimate of the node coordinates and using the PRORUSTES to analysis alignment of the coordinate and final position coordinates of nodes etc. There are four steps, and the thesis gives specific implementation steps of the algorithm. Finally, compared with stochastic algorithms and classical MDS algorithm experiment, the thesis takes application of specific examples. Experimental results show that: the proposed localization algorithm has fast multidimensional scaling positioning accuracy in ensuring certain circumstances, but also greatly improves the speed of operation.

Genomic analysis of neural crest induction

The vertebrate neural crest is a migratory stem cell population that arises within the central nervous system. Here, we combine embryological techniques with array technology to describe 83 genes that provide the first gene expression profile of a newly induced neural crest cell. This profile contains numerous novel markers of neural crest precursors and reveals previously unrecognized similarities between neural crest cells and endothelial cells, another migratory cell population. We have performed a secondary screen using in situ hybridization that allows us to extract temporal information and reconstruct the progression of neural crest gene expression as these cells become different from their neighbors and migrate. Our results reveal a sequential `migration activation' process that reflects stages in the transition to a migratory neural crest cell and suggests that migratory potential is established in a pool of cells from which a subset are activated to migrate.
A Population Where Men Live As Long As Women: Villagrande Strisaili, Sardinia

Usually women live longer than men and female centenarians largely outnumber male centenarians. The findings of previous studies identifying a population with a femininity ratio close to 1.0 among centenarians in the mountainous region of Sardinia was the starting point of an in-depth investigation in order to compare mortality trajectories between men and women in that population. The exceptional survival of men compared to women emerges from the comparison with similar Italian data. Age exaggeration for men has been strictly excluded as a result of the age validation procedure. The discussion suggests that besides biological/genetic factors, the behavioral factors including life style, demographic behavior, family support, and community characteristics may play an important role. No single explanation is likely to account for such an exceptional situation and a fully integrated multidisciplinary approach is urgently needed.
Dichlorvos degradation of stored wheat and resulting milling fractions.

Dichlorvos sprayed on wheat at 15 ppm resulted in deposits ranging from 2.4 to 6.0 ppm immediately after treatment. Residues decreased to 0.5 ppm or less during 6 weeks of storage in 3.5-m3 bins. Temperature of the grain was an important factor affecting residue-degradation rate. There was little or no loss of residues from wheat stored for 3 months at -18°C. The residues on wheat stored at 27°C for 1 week was about equal to that stored in bins at 18 to 12.7°C for 5-6 weeks. Residues on the milling fractions were greater on the bran and shorts than on the flour. The treatment did not adversely affect patent flour or bread baked from the patent flour.
Adapalene gel, 0.1%, as maintenance therapy for acne vulgaris: a randomized, controlled, investigator-blind follow-up of a recent combination study.

OBJECTIVE To assess the maintenance effect of adapalene gel, 0.1%, relative to gel vehicle in subjects successfully treated in a previous 12-week study of adapalene-doxycycline, 100 mg, combination therapy. DESIGN Multicenter, investigator-blind, randomized, controlled study. SETTING Thirty-four US centers. SUBJECTS A total of 253 subjects with severe acne vulgaris who showed at least moderate improvement from baseline (50% improvement from baseline) when treated with either adapalene plus doxycycline or doxycycline plus gel vehicle in a previous 12-week study. INTERVENTIONS Subjects were randomized to receive adapalene gel, 0.1%, or gel vehicle once daily for 16 weeks. MAIN OUTCOME MEASURES Efficacy and safety criteria included maintenance rate (subjects maintaining at least 50% improvement in lesion counts from previous therapy), lesion counts (total, inflammatory, and noninflammatory), global severity assessment, cutaneous tolerability, and adverse events. RESULTS Adapalene maintenance therapy resulted in significantly larger maintenance rates (75% vs 54%; P<.001) and significantly lower lesion counts (total [P = .005], inflammatory [P = .01], and noninflammatory [P = .02]) compared with gel vehicle. Adapalene was safe and well tolerated in this study. Conclusion This study demonstrates a clinical benefit of continued treatment with adapalene gel, 0.1%, as a maintenance therapy for acne.
The state of knowledge of chronic depression.

The Definition of Chronic Depression Dr. Gelenberg: Let’s begin with a discussion of the definition of chronic depression. What is the clinical relevance of the subtypes of depression in the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV)? Dr. McCullough: My colleagues and I have reported on 1316 patients with chronic depression. We found no differences when a wide variety of demographic, psychosocial, and health measures were compared. For the DSM-V, we have argued that the existing subtypes do not represent qualitatively distinct entities. We have recommended a 2-by-2 table to accommodate a 4-fold classification of the unipolar disorders: mild versus moderate-to-severe severity and acute versus chronic types of episodes (Table 1). We can greatly simplify the current subtypes of chronic depression by consolidating them into a single category termed chronic depression. Dr. Gelenberg: Will you define chronic depression? Dr. McCullough: Chronic depression lasts a minimum of 2 years without at least a 2-month hiatus or a full remission. We are not suggesting the elimination of the DSM-IV categories for depressive disorders, but are recommending the deletion of distinct chronic subtypes since these subtypes do not represent qualitatively different entities. Dr. Ninan: Perhaps we should review the current diagnostic criteria for depressive disorders. The criteria for dysthymia require depressed mood for the majority of time and 2 additional symptoms that persist for 2 years, while the criteria for a major depressive episode stipulate 5 or more symptoms, including depressed mood or anhedonia, persisting for at least 2 weeks. Dysthymia followed by a major depressive episode is frequently labeled double depression. In the DSM-IV, chronic depression is defined as the persistence of the full criteria for a major depressive episode for at least 2 years. Major depressive disorder with incomplete recovery occurs when enough symptoms improve that the patient no longer meets the full criteria for major depressive disorder, but still has residual symptoms of depression (i.e., subsyndromal depression). If that patient later meets the full criteria for a major depressive episode without a period of remission in between, we consider it another episode of major depression (i.e., 2 episodes with incomplete recovery in between). Dr. McCullough: On our 2-by-2 table, we recommend maintaining dysthymia on the chronic row and in the mild severity column. Most of the disorders that Dr. Ninan just delineated would be in the moderateto-severe column. On the acute episode row, the mild disorder would be labeled minor depressive disorder and the moderate-to-severe episode would be termed episodic major depression. Dan N.

CONCENTRATION AND EMISSIONS OF AMMONIA AND PARTICULATE MATTER IN TUNNEL–VENTILATED BROILER HOUSES UNDER SUMMER CONDITIONS IN TEXAS

Total suspended particulate (TSP) concentrations, ammonia (NH3) concentrations, and ventilation rates were measured in four commercial, tunnel–ventilated broiler houses in June through December of 2000 in Brazos County, Texas. TSP and NH3 concentrations ranged from 7,387 to 11,387 . g m–3 and 2.02 to 45 ppm, respectively. Ammonia concentration exhibited a correlation with the age of the birds. Mass median diameters (MMD) of the TSP samples were between 24.0 and 26.7 . m aerodynamic equivalent diameter. MMD increased with bird age. The mass fraction of PM10 in the TSP samples was between 2.72% and 8.40% with a mean of 5.94%. Ventilation rates were measured between 0.58 and 89 m3 s–1. Measured concentrations of PM10 and ammonia were multiplied by the measured ventilation rates to calculate emission rates for PM10 and ammonia. Ammonia emission rates varied from 38 to 2105 g hr–1. TSP emission rates and PM10 emission rates ranged from 7.0 to 1673 g hr–1 and 0.58 to 99 g hr–1, respectively. Emission rates for ammonia and particulate matter increased with the age of the birds. Most of the PM in the commercial broiler houses was large enough to be captured by the human or poultry respiratory system prior to being inhaled into the lungs.
