We discuss an enhancement of the Balas-Jeroslow procedure for strengthening disjunctive cuts for mixed 0-1 programs. It is based on the paradox that sometimes weakening a disjunction helps the strengthening procedure and results in sharper cuts. When applied to a split cut derived from a source row of the simplex tableau, the enhanced procedure yields, besides the Gomory Mixed Integer cut (GMI)...
Observationally derived transport diagnostics for the lowermost stratosphere and their application to the GMI chemistry and transport model S. E. Strahan, B. N. Duncan, and P. Hoor Goddard Earth Science and Technology Center, University of Maryland, Baltimore County, Baltimore, MD 21250, USA Max Planck Institute for Chemistry, Air Chemistry, Mainz, Germany Received: 8 January 2007 – Accepted: 2...
Methane (CH4) is the second most important greenhouse gas (GHG) in terms of its concentration and impact on climate. In present study, we investigate trends, sources distribution CH4 South Africa. The study uses satellite datasets from Sentinel-5P Atmospheric Infrared Sounder (AIRS). also credible World Bank, Statistics Africa Global Initiative (GMI). results show an increasing trend 1970–1989....
Herein, detailed studies on the influence of stress annealing magnetic softness and giant magnetoimpedance (GMI) ratio Co69.2Fe3.6Ni1B12.5Si11Mo1.5C1.2 glass-coated microwires are provided. As-prepared microwire presents linear hysteresis loops, moderate GMI with double-peak field dependence low coercivity (4 A m?1), typically observed for wires transverse anisotropy. However, after conventiona...
Precipitation type is a key parameter used for better retrieval of precipitation characteristics as well to understand the cloud–convection–precipitation coupling processes. Ice crystals and water droplets inherently exhibit different in regimes (e.g., convection, stratiform), which reflect on satellite remote sensing measurements that help us distinguish them. The Global Measurement (GPM) Core...
10 The constellation of space-borne passive microwave (MW) sensors, coordinated under 11 the framework of the Precipitation Measurement Missions international agreement, 12 continuously produces observations of clouds and precipitation all over the globe. The Goddard 13 Profiling Algorithm (GPROF) is designed to infer the instantaneous surface precipitation rate 14 from the measured MW radiance...
The Global Meningococcal Initiative (GMI) is a global expert group that includes scientists, clinicians, and public health officials with a wide range of specialties. The purpose of the Initiative is to promote the global prevention of meningococcal disease (MD) through education, research, and cooperation. The first Asia-Pacific regional meeting was held in November 2014. The GMI reviewed the ...
This paper presents design methods for highly efficient optimisation of geometrically shaped constellations to maximise data throughput in optical communications. It describes analytically calculate the information-theoretical loss and gradient this as a function input constellation shape. The gradients mutual information (MI) generalised (GMI) are critical geometrically-shaped constellations. ...
Diabetes is reported to be more common in people living with HIV (PLWH). There not an internationally agreed screening method for diabetes PLWH due reports that HbA1c falsely low this group. Continuous glucose monitoring (CGM) has been used explore and discrepancy. Its role identification of dysglycaemia known data from Southern Africa are scarce. To the relationship between interstitial glucos...
