Subband decomposition techniques for adaptive channel equalisation

In this contribution, the convergence behaviour of the adaptive linear equaliser based on subband decomposition technique is investigated. Two different subband-based linear equalisers are employed, with the aim of improving the equaliser's convergence performance. Simulation results over three channel models having different spectral characteristic are presented. Computer simulations indicate that subband-based equalisers outperform the conventional fullband linear equaliser when channel exhibit severe spectral dynamic. Convergence rate of subband equalisers are governed by the slowest subband, whereby different convergence behaviour in each individual subband is observed. Finally, the complexity of fullband and subband equalisers is discussed

THE CONTRIBUTION OF SIMPLE PRESENT TENSE MASTERY TOWARD SPEAKING ABILITY OF THE SECOND YEAR STUDENTS OF ISLAMIC SENIOR HIGH SCHOOL AL-QASIMIYAH SOREK 1 PELALAWAN REGENCY

This research is aimed at finding out the contribution of simple present tense mastery toward speaking ability. The subject of this research is the second year students of Islamic Senior High School Al-Qasimiyah Sorek 1 whereas; the objects of this research are students’ simple present tense mastery and their speaking ability. The population of this research is 35 students. Because the number of population is lower than 100, the writer takes all population as sample. In this case, the writer uses the total sampling technique. In collecting data, the writer used test. The test was used to find out the contribution of simple present tense mastery toward students’ speaking ability. In analyzing data, the writer uses the simple regression analysis. The simple regression formula is as follows: Based on data analysis, done by using SPSS 17.0 version program, it can be seen that Fo is 18.121. it is higher than F table either at 5% or 1%. At level 5%, F table is (4.13) and at level 1%, F table is (7.44). So that, the writer can conclude that Ho is rejected and Ha is accepted. It means that there is a positive significant contribution of X toward Y (students’ simple present tense mastery toward speaking ability of the second year students of Islamic Senior High School Al- Qasimiyah Sorek 1 Pelalawan Regency). The percentage of the contribution of simple present tense mastery toward speaking ability is 35% after calculating r².100. It means that the contribution of simple present tense mastery toward speaking ability is 35% and the rest 65% is influenced by other factors. Finally, in accordance with writer’s investigation, the students’ simple present tense mastery is classified into enough and the students’ speaking ability is classified into good

Iconic memory of icon?

The objectives of the present commentary are to show that (1) one important theoretical property of iconic memory is inconsistent with a retinotopic icon, (2) data difficult for the notion of an icon do not necessarily challenge the notion of an iconic store, (3) the iconic store, as a theoretical mechanism, is an ecologically valid one, and (4) the rationale of experimentation is such that the experimental task need not mimic the phenomenon being studied

Is Simpler Always Better? Consumer Evaluations of Front-of-Package Nutrition Symbols

Consumers of packaged goods products in the United States recently have faced an onslaught of front-of-package (FOP) nutrition symbols and icons, including the controversial “Smart Choices” single summary indicator. In a between-subjects experiment with 520 adult consumers, the authors compare effects of the Smart Choices (SC) icon, the more complex Traffic Light–Guideline Daily Amounts (TLGDAs) icon, and a no-FOP icon control for a nutritionally moderate food that qualifies for the SC icon. Drawing from principles of heuristic processing and halo effects, the authors predict and find that the SC icon can lead to positive (and potentially misleading) nutrient evaluations and product healthfulness when compared with the TL-GDA icon or no-FOP icon control. When the Nutrition Facts Panel is not available, the TL-GDA icon results in substantially greater nutrition accuracy scores than with the SC icon or control. The authors also find that nutrition consciousness is more likely to moderate effects related to the Nutrition Facts Panel than the FOP nutrition icon information. Implications are offered for public health officials, nutrition researchers, and food manufacturers, as the Food and Drug Administration considers FOP nutrition alternatives for use in the United States

International consensus on (ICON) anaphylaxis

ICON: Anaphylaxis provides a unique perspective on the principal evidence-based anaphylaxis guidelines developed and published independently from 2010 through 2014 by four allergy/immunology organizations. These guidelines concur with regard to the clinical features that indicate a likely diagnosis of anaphylaxis -- a life-threatening generalized or systemic allergic or hypersensitivity reaction. They also concur about prompt initial treatment with intramuscular injection of epinephrine (adrenaline) in the mid-outer thigh, positioning the patient supine (semi-reclining if dyspneic or vomiting), calling for help, and when indicated, providing supplemental oxygen, intravenous fluid resuscitation and cardiopulmonary resuscitation, along with concomitant monitoring of vital signs and oxygenation. Additionally, they concur that H1-antihistamines, H2-antihistamines, and glucocorticoids are not initial medications of choice. For self-management of patients at risk of anaphylaxis in community settings, they recommend carrying epinephrine auto-injectors and personalized emergency action plans, as well as follow-up with a physician (ideally an allergy/immunology specialist) to help prevent anaphylaxis recurrences. ICON: Anaphylaxis describes unmet needs in anaphylaxis, noting that although epinephrine in 1 mg/mL ampules is available worldwide, other essentials, including supplemental oxygen, intravenous fluid resuscitation, and epinephrine auto-injectors are not universally available. ICON: Anaphylaxis proposes a comprehensive international research agenda that calls for additional prospective studies of anaphylaxis epidemiology, patient risk factors and co-factors, triggers, clinical criteria for diagnosis, randomized controlled trials of therapeutic interventions, and measures to prevent anaphylaxis recurrences. It also calls for facilitation of global collaborations in anaphylaxis research. In addition to confirming the alignment of major anaphylaxis guidelines, ICON: Anaphylaxis adds value by including summary tables and citing 130 key references. It is published as an information resource about anaphylaxis for worldwide use by healthcare professionals, academics, policy-makers, patients, caregivers, and the public

The upper-atmosphere extension of the ICON general circulation model (version: Ua-icon-1.0)

How the upper-atmosphere branch of the circulation contributes to and interacts with the circulation of the middle and lower atmosphere is a research area with many open questions. Inertia-gravity waves, for instance, have moved in the focus of research as they are suspected to be key features in driving and shaping the circulation. Numerical atmospheric models are an important pillar for this research. We use the ICOsahedral Non-hydrostatic (ICON) general circulation model, which is a joint development of the Max Planck Institute for Meteorology (MPI-M) and the German Weather Service (DWD), and provides, e.g., local mass conservation, a flexible grid nesting option, and a non-hydrostatic dynamical core formulated on an icosahedral-triangular grid. We extended ICON to the upper atmosphere and present here the two main components of this new configuration named UA-ICON: an extension of the dynamical core from shallow- to deep-atmosphere dynamics and the implementation of an upper-atmosphere physics package. A series of idealized test cases and climatological simulations is performed in order to evaluate the upper-atmosphere extension of ICON. © Author(s) 2019
