Effect of a package of health and nutrition services on sustained recovery in children after moderate acute malnutrition and factors related to sustaining recovery: a cluster-randomized trial
moderate acute malnutrition ready-to-use supplementary food relapse supplemental feeding program sustained recovery wasting
2018/11/15
Background: Children who recover from moderate acute malnutrition (MAM) have high rates of relapse in the year after nutritional recovery. Interventions to decrease these adverse outcomes are needed t...
The National Oceanographic Partnership Program,Ocean.US,and Real Movement Towards an Integrated and Sustained Ocean Observing System
National Oceanographic Partnership Program Ocean.US Real Movement Towards an Integrated Ocean Observing System
2015/7/31
The National Oceanographic Partnership Program (NOPP) was legislatively established in 1997 in Public Law 104-201 to promote a number of national goals through improved knowledge of the oceans and to ...
Observing the Ocean with Autonomous and Lagrangian Platforms and Sensors:The Role of ALPS in Sustained Ocean Observing Systems
Autonomous Lagrangian Platforms Sensors ALPS Sustained Ocean Observing Systems
2015/7/31
Oceanographers have long dreamed of a detailed, 4-D view of the ocean. The last decade has witnessed a revolution in autonomous ocean observing capabilities as new platforms and sensors developed, and...
Bio-Polymer Hairpin Loops Sustained by Polarons
Bio-Polymer Hairpin Loops Sustained Polarons Biological Physics
2012/4/19
We show that polarons can sustain loop-like configurations in flexible bio-polymers and that the size of the loops depend on both the flexural rigidity of the polymer and the electron-phonon coupling ...
A sustained oscillation in a toy-model of the coupled atmosphere-ocean system
toy-model the coupled atmosphere-ocean system
2011/8/31
Interaction between atmospheric mid-latitude flow and wind-driven ocean circulation is studied coupling two idealized low-order spectral models. The barotropic Charney-DeVore model with three componen...
Nonequilibrium free energy, H theorem and self-sustained oscillations for Boltzmann-BGK descriptions of semiconductor superlattices
Nonequilibrium processes Boltzmann equation current fluctuations
2010/11/22
Semiconductor superlattices (SL) may be described by a Boltzmann-Poisson kinetic equation with a Bhatnagar-Gross-Krook (BGK) collision term which preserves charge, but not momentum or energy.
The baroclinic instability in the context of layered accretion. Self-sustained vortices and their magnetic stability in local compressible unstratified models of protoplanetary disks
baroclinic instability magnetic stability protoplanetary disks
2010/11/10
Context. Turbulence and angular momentum transport in accretion disks remain a topic of debate. With the realization that dead zones are robust features of protoplanetary disks, the search for hydrody...
Global stability analysis of birhythmicity in a self-sustained oscillator
Global stability birhythmicity self-sustained oscillator
2010/4/1
We analyze global stability properties of birhythmicity in a self-sustained system with random excitations. The model is a multi-limit cycles variation of the van der Pol oscillatorintroduced to analy...
Structure and control of self-sustained target waves in excitable small-world networks
self-sustained target waves small-world networks dominant phase-advanced driving
2010/4/1
Small-world networks describe many important practical systems among which neural networks consisting of excitable nodes are the most typical ones. In this paper we study self-sustained oscillations o...
Quantum noise and self-sustained radiation of PT-symmetric systems
Quantum noise self-sustained radiation PT-symmetric systems
2010/3/10
The observation that PT-symmetric Hamiltonians can have real-valued energy levels even if they are non-hermitian has triggered intense activities, with experiments in particular focusing on optical sy...
Self-sustained oscillator as a model for explosion quakes at Stromboli Volcano
Self-sustained oscillator model for explosion quakes Stromboli Volcano
2009/11/12
We analyze seismic signals produced by explosion-quakes at Stromboli Volcano. We use standard nonlinear procedures to search a low-order effective dynam-ics. The dimension of the reconstructed phase s...
Physicochemical Characterization of Orally-Active Meglumine Antimoniate/Beta-Cyclodextrin Nanoassemblies: Non-Inclusion Interactions and Sustained Drug Release Properties

b-cyclodextrin (b-CD) is widely used as a component of pharmaceutical formulations, classically to improve the solubility and oral bioavailability of poorly water-soluble drugs through formation of dr...
The authors describe a self-sustaining baroclinic inertial oscillation whose energy source rests in a uniform horizontal temperature gradient. This energy is released through the agency of a stratific...
Linear versus Self-Sustained Interdecadal Thermohaline Variability in a Coupled Box Model

2008/11/24
Recent studies of decadal/interdecadal climate variability suggested two main classes of mechanisms: self-sustained (supercritical) oscillations due to the internal nonlinearity of the ocean and linea...
