A quantum trampoline for ultra-cold atoms

We have observed the interferometric suspension of a free-falling Bose-Einstein condensate periodically submitted to multiple-order diffraction by a vertical 1D standing wave. The various diffracted matter waves recombine coherently, resulting in high contrast interference in the number of atoms detected at constant height. For long suspension times, multiple-wave interference is revealed through a sharpening of the fringes. We use this scheme to measure the acceleration of gravity

Decision-making in drug development using a composite definition of success

Evidence-based quantitative methodologies have been proposed to inform decision-making in drug development, such as metrics to make go/no-go decisions or predictions of success, identified with statistical significance of future clinical trials. While these methodologies appropriately address some critical questions on the potential of a drug, they either consider the past evidence without predicting the outcome of the future trials or focus only on efficacy, failing to account for the multifaceted aspects of a successful drug development. As quantitative benefit-risk assessments could enhance decision-making, we propose a more comprehensive approach using a composite definition of success based not only on the statistical significance of the treatment effect on the primary endpoint but also on its clinical relevance and on a favorable benefit-risk balance in the next pivotal studies. For one drug, we can thus study several development strategies before starting the pivotal trials by comparing their predictive probability of success. The predictions are based on the available evidence from the previous trials, to which new hypotheses on the future development could be added. The resulting predictive probability of composite success provides a useful summary to support the discussions of the decision-makers. We present a fictive, but realistic, example in major depressive disorder inspired by a real decision-making case

Graduate Management Admission Test Outcomes And The Academic Achievement: A Study On Masters Of Business Administration Students At Makerere University, Uganda

This study investigates whether the outcomes of the Graduate Management Admission Test (GMAT) can predict the academic achievement of enrollees in masters programs. The study is based on administrative data of 516 Masters of Business Administration (MBA) enrollees at the College of Business and Management Science, Makerere University in the 2011 and 2012 enrollment cohorts. The Cumulative Grade Point Average (CGPA) in the bachelor’s degree and that of the first year of master’s studies were adopted as measures of the academic achievement of enrollees. In the analysis, academic achievement of MBA enrollees was modeled using a robust regression by GMAT scores obtained during admission to the program and student characteristics—gender, other qualification, year of completion and outcome of the bachelor’s degree, and whether the candidate obtained his/her bachelor’s degree from Makerere University. In the results, a high GMAT score was significantly associated with high academic achievement among graduate students. This evidence suggests that the theory of an aptitude or admission test being a predictor of academic achievement of learners holds across disciplines. However, a significant association established in the results between the academic achievement of learners at the undergraduate and graduate stages indicates that the undergraduate achievement can be recommended as a cost free alternative for assessing the competence of candidates suitable for admission to the graduate program

Academic Achievement Of Ugandan Sixth Grade Students: Influence Of Parents Education Levels

The study investigates the influence of a father and mothers education on the academic achievement of their child. The investigation is based on data sourced from the 2009 Southern African Consortium for Monitoring Education Quality survey comprising 5,148 records of sixth grade students enrolled in Ugandan primary schools. Students percentage scores in the health sciences, reading, and numeracy tests were adopted as a measure of academic achievement. The analysis was carried out using summary statistics and a multiple linear regression clustered by six geographical regions in Uganda: central, eastern, western, northern, southwestern, and northeastern. In addition to father and mothers education, students test scores in the various disciplines were analyzed by the characteristics of age, sex, rural-urban residence, grade repetition status (any grade), and length of pre-primary education. The results showed that the level of a fathers education required to predict whether the child will achieve better scores in all disciplines was primary education. However, a mother required secondary and post-secondary education to enable the child to obtain better scores in reading and numeracy, respectively. Much of the previous literature has suggested that children born to educated parents have higher academic achievement; the results of this study support this finding but also reveal a difference in the levels of a father and mothers education required to predict their childs achievement of better scores in formal education

Space optical instruments optimisation thanks to CMOS image sensor technology

Today, both CCD and CMOS sensors can be envisaged for nearly all visible sensors and instruments designed for space needs. Indeed, detectors built with both technologies allow excellent electro-optics performances to be reached, the selection of the most adequate device being driven by their functional and technological features and limits. The first part of the paper presents electro-optics characterisation results of CMOS Image Sensors (CIS) built with an optimised CMOS process, demonstrating the large improvements of CIS electro-optics performances. The second part reviews the advantages of CMOS technology for space applications, illustrated by examples of CIS developments performed by EADS Astrium and Supaéro/CIMI for current and short term coming space programs
