Comparison of a Barbell Weight Training Program to a Universal Gym Weight Training Program on the Development of Leg Strength in Secondary School Boys
In the United States over the past few years a great number of conditioning machines have been purchased by schools, clubs, hospitals and private citizens to supplement or replace barbell weight training equipment. Some reasons given for the recent popularity of the new weight training machines over the more conventional barbells are that they: provide greater safety, save time, and do the job as well or better than conventional barbells.
Studies showing strength increase involving barbell weight training, or isotonic training, as well as those involving isometric training have been quite popular. Yet despite the many studies there appears to be a lack of information on the comparison of a barbell weight training program and a weight training program which utilizes a conditioning machine such as the universal gym.
Due to the lack of information on comparing the barbell weight training program and the conditioning machine weight training program the author believes this study will be of value as a source of information pertaining to the comparison of the similar yet different weight lifting programs

A whole-health-economy approach to antimicrobial stewardship: Analysis of current models and future direction.
Antimicrobial stewardship (AMS) strategies are widely implemented in single healthcare sectors and organisations; however, the extent and impact of integrated AMS initiatives across the whole health economy are unknown.
Assessing degree of integration of AMS across the whole health economy and its impact is essential if we are to achieve a ‘One Health’ approach to addressing antimicrobial resistance (AMR), and therefore we searched systematically for and analysed published examples of integrated AMS initiatives to address this gap.
Application of a system-level framework to analyse integration of AMS initiatives across and within healthcare sectors shows that integration is emerging but needs strengthening.
Findings from a small number of evaluations in high-income countries suggest that antimicrobial prescribing and healthcare-associated infections can be reduced using a multisectoral integrated AMS approach.
More robust research designs to evaluate and understand the impact of multisectoral integrated AMS are needed, particularly with respect to differing health systems in different countries and local organisational contexts.
Our analysis highlights a number of challenges and ways forward for enhancing the delivery of AMS through an integrated approach
Quantifying mixed-state quantum entanglement by optimal entanglement witness
We develop an approach of quantifying entanglement in mixed quantum states by
the optimal entanglement witness operator. We identify the convex set of mixed
states for which a single witness provides the exact value of an entanglement
measure, and show that the convexity, properties, and symmetries of
entanglement or of a target state considerably fix the form of the optimal
witness. This greatly reduces difficulty in computing and experimentally
determining entanglement measures. As an example, we show how to experimentally
quantify bound entanglement in four-qubit noisy Smolin states and three-qubit
Greenberger-Horne-Zeilinger (GHZ) entanglement under white noise. For general
measures and states, we provide a numerical method to efficiently optimize
witness.Comment: Supplemental material is include
Recursive relations for a quiver gauge theory
We study the recursive relations for a quiver gauge theory with the gauge
group with bifundamental fermions transforming as
. We work out the recursive relation for the amplitudes
involving a pair of quark and antiquark and gluons of each gauge group. We
realize directly in the recursive relations the invariance under the order
preserving permutations of the gluons of the first and the second gauge group.
We check the proposed relations for MHV, 6-point and 7-point amplitudes and
find the agreements with the known results and the known relations with the
single gauge group amplitudes. The proposed recursive relation is much more
efficient in calculating the amplitudes than using the known relations with the
amplitudes of the single gauge group.Comment: 33 pages and 2 figures, minor correction
