Dynamic ileal pouch emptying studies

Abdominal Radiology, 2023
Although much radiologic literature has focused on the short-term post-operative complications associated with ileal pouches, as the number of patients with long-term pouches has grown, there is increasing realization of the functional deficits that may occur long after pouch creation.

World Dynamics: A Dynamic Optimization Study

1974
In a simplified version of Forrester’s world-model control variables have been built in in order to influence the course of world development. A criterion has been defined which is optimized with respect to these controls.

Actin: Static and Dynamic Studies

2023
The actin cytoskeleton is a highly dynamic network in plant cells, which is precisely regulated by numerous actin-binding proteins. Hence, characterizing the biochemical activities of actin-binding proteins is of great importance. Here we describe methods for determining the binding and bundling of microfilaments as well as methods for visualizing ...

Aqueous humor dynamics: Experimental studies

Experimental Eye Research, 1973
Abstract Experimental measurements have been made in vitro of the reflection coefficient (σs) of the ciliary epithelium to NaCl, sucrose, urea and dextran, with the first three substances having a σ of 0·02 and dextran a σ of unity. Plasma or blood separated from aqueous or Ringer by the ciliary epithelium exerted an osmotic pressure of 20·8 mmHg. In

Experimental Studies of Extinction Dynamics

Science, 1999
Extinction of populations occurs naturally, but global extinction rates are accelerating, making understanding extinction a high priority for conservation. Extinction in experimental populations of brine shrimp ( Artemia franciscana ) was measured to assess hypothesized extinction processes.

Nonlinear Lattice Dynamics: Molecular Dynamics Studies

1978
Nonlinearity combined with dispersion were essential aspects in various contexts for many decades but have enjoyed remarkable revival of interest in the last few years [1,2]. The topic we wish to discuss here is structurally-commensurate lattice systems reducing in the continuum limit to the Φ4 Hamiltonian and exhibiting a distortive phase transition ...

NDlib: Studying Network Diffusion Dynamics

2017 IEEE International Conference on Data Science and Advanced Analytics (DSAA), 2017
Nowadays the analysis of diffusive phenomena occurring on top of complex networks represents a hot topic in the Social Network Analysis playground. In order to support students, teachers, developers and researchers in this work we introduce a novel simulation framework, NDlib.

Dynamic system reliability study modeling

Conference Record of 1998 Annual Pulp and Paper Industry Technical Conference (Cat. No.98CH36219), 1999
This article extends conventional reliability modeling to a comprehensive modeling to cover system dynamic response and plant process response as the consequence of system component failures. The study results indicate the load outages from system dynamic response and process response cannot be neglected-they may have significant contributions to the ...

Studying Organizational Dynamics

Simulation & Gaming, 1998
The idea ofprocess is prominent in organization theory but less so in research. Limited access to organizations is a likely explanation, particularly because process analysis often requires detailed data. Experimental research may provide the necessary data, if only a method is used that allows the situation under study to change as a result of actors

Experimental study of dripping dynamics

Physical Review E, 2002
The dependence of dripping dynamics from physical properties of the nozzles is investigated. The analysis is performed by means of two complementary methods: (i) long dripping time series recorded with a standard laser-beam apparatus; and (ii) drop formations observed with a fast digital camcorder.
