Dynamic systems development : Towards continuity, growth and evolution
(IEEE COMPUTER SOC, 2003)The dynamic nature of knowledge and software evolution and usage present a pervasive challenge to system developers. Discrete attempts to create such systems often lead to a mismatch between system, expectation and a ... -
A dynamic topical hydrofluoroalkane foam to induce nanoparticle modification and drug release in situ
(2009-08)Topical nanoparticles are usually applied using semi-solid formulations, but the delivery process is often inefficient due to the poor drug release from the particles. The aim of this study was to investigate the capability ... -
Dynamic Virtual Page-based Flash Translation Layer with Novel Hot Data Identification and Adaptive Parallelism Management
(2018-09-28)Solid-state disks (SSDs) tend to replace traditional motor-driven hard disks in high-end storage devices in past few decades. However, various inherent features, such as out-of-place update [resorting to garbage collection ... -
A dynamical analysis of the HII galaxy II Zwicky 33 and its low surface brightness companion
(1997)We present radio and optical observations and an analysis of the dynamics of the H II galaxy II Zw 33 and its Low Surface Brightness companion. Both galaxies were observed in the radio with the VLA in its B- and C-array ... -
Dynamical Downscaling Approach for Wintertime Seasonal-Scale Simulation over the Western Himalayas
(2014-08-01)The performance of RegCM4 for seasonal-scale simulation of winter circulation and associated precipitation over the Western Himalayas (WH) is examined. The model simulates the circulation features and precipitation in three ... -
The dynamical evolution of molecular clouds near the Galactic Centre - I. Orbital structure and evolutionary timeline
(2015-02-21)We recently proposed that the star-forming potential of dense molecular clouds in the Central Molecular Zone (CMZ, i.e. the central few 100 pc) of the Milky Way is intimately linked to their orbital dynamics, potentially ... -
The dynamical evolution of molecular clouds near the Galactic Centre - II. Spatial structure and kinematics of simulated clouds
(2019-04-21)The evolution of molecular clouds in galactic centres is thought to differ from that in galactic discs due to a significant influence of the external gravitational potential. We present a set of numerical simulations of ... -
The dynamical evolution of molecular clouds near the Galactic Centre -- III. Tidally--induced star formation in protocluster clouds
(2019-04-02)As part of a series of papers aimed at understanding the evolution of the Milky Way's Central Molecular Zone (CMZ), we present hydrodynamical simulations of turbulent molecular clouds orbiting in an accurate model of the ... -
Dynamical evolution of star-forming regions
(2014-02-01)We model the dynamical evolution of star-forming regions with a wide range of initial properties. We follow the evolution of the regions' substructure using the Q-parameter, we search for dynamical mass segregation using ... -
Dynamically Tagged Groups of Very Metal-poor Halo Stars from the HK and Hamburg/ESO Surveys
(2021-01-20)We analyze the dynamical properties of ∼1500 very metal-poor (VMP; [Fe/H] ≲−2.0) halo stars, based primarily on medium-resolution spectroscopic data from the HK and Hamburg/ESO surveys. These data, collected over the past ... -
A dynamically-packed planetary system around GJ 667C with three super-Earths in its habitable zone
(2013-08-07)Context. Since low-mass stars have low luminosities, orbits at which liquid water can exist on Earth-sized planets are relatively close-in, which produces Doppler signals that are detectable using state-of-the-art Doppler ... -
Dynamics analysis and image encryption application of Hopfield neural network with a novel multistable and highly tunable memeristor
(2023-11-18)Building artificial neural network models and studying their dynamic behaviors is extremely important from both a theoretical and practical standpoint due to the rapid advancement of artificial intelligence . In addition ... -
The Dynamics and Distribution of Angular Momentum in HiZELS Star-Forming Galaxies at z = 0.8 - 3.3
(2019-06)We present adaptive optics assisted integral field spectroscopy of 34 star-forming galaxies at z = 0.8-3.3 selected from the HiZELS narrow-band survey. We measure the kinematics of the ionized interstellar medium on ∼1 kpc ... -
Dynamics and Energy Loss in Superbubbles
(2014-10-01)Interstellar bubbles appear to be smaller in observations than expected from calculations. Instabilities at the shell boundaries create three-dimensional (3D) effects and are probably responsible for part of this discrepancy. ... -
The dynamics and environmental impact of 3C452
(2011)We present a detailed analysis of a new XMM-Newton observation of the Fanaroff-Riley type II (FR II) radio galaxy 3C452 and its environment. We detect X-ray emission from the hot intragroup medium and measure its temperature ... -
Dynamics and feedback loops in the transforming growth factor β signaling pathway
(2012-03-01)Transforming growth factor β (TGF-β) ligands activate a signaling cascade with multiple cell context dependent outcomes. Disruption or disturbance leads to variant clinical disorders. To develop strategies for disease ... -
Dynamics of aerosol size during inhalation : Hygroscopic growth of commercial nebulizer formulations
(2014-03-10)The size of aerosol particles prior to, and during, inhalation influences the site of deposition within the lung. As such, a detailed understanding of the hygroscopic growth of an aerosol during inhalation is necessary to ... -
The Dynamics of Collaboration in Multipartner Projects
(2010-09)In many project-based industries, there has recently been an increased tendency for collaboration and cocreation of value with the customers. However, many existing studies report inherent challenges and complexities related ... -
