• Produces optimized non-uniform set of speed levels • Enables dynamic, traffic-responsive grouping • Reduces transit times and attack rates compared to the existing group transit scheme with fixed schedules and uniform speed levels Randomized Transit Routing • Randomizes vessel transit routes to make them maximally unpredictable and reduces attack rates • Utilizes the transit game model (twopl...
OBJECTIVE To evaluate the effects of conventional treatment of chronic functional constipation on total and segmental colonic transit times and on orocecal transit time. METHODS A total of 34 consecutive patients with functional constipation attending a specialized outpatient clinic were included in the study. Total and segmental colonic transit times were assessed using radiopaque markers. H...
Severe idiopathic constipation can be categorised based on physiological testing into subgroups including slow transit constipation and pelvic floor dysfunction. This study aimed to determine if colonic and psychological symptoms, or rectosigmoid transit times, could discriminate among these subgroups. Patients, categorised according to total colonic transit times and pelvic floor function test...
Arc diagrams allow exploring relations and their strength between sequential nodes. Previous solutions suffer from displaying all arcs at the center of a node, which can lead to visual obstruction. We present a new technique, which extends the arc diagram technique by laying out the weighted edges of a node adjacent to each other. The aim of our Sankey Arc technique is to improve clarity, to en...
Tunnelling transit time for a frustrated total internal reflection (FTIR) in a double–prism experiment was measured using microwave radiation. We have found that the transit time is of the same order of magnitude as the corresponding transit time measured either in an undersized wave-guide (evanescent modes) or in a photonic lattice. Moreover we have established that in all such experiments the...
[Purpose] This study aimed to examine the effects of interventions on constipation and to provide basic data for physical therapy in internal medicine. [Subjects and Methods] The colon transit times of 30 subjects were measured and after the interventions. Fifteen subjects were assigned to a Maitland orthopedic manual therapy group, and 15 subjects were assigned to a dietary fiber group. [Resul...
UNLABELLED The purpose of this study was to determine the orogastric transit time of standard 131I capsules and the incidence of transit delay. METHODS We studied 58 consecutive subjects receiving outpatient diagnostic and therapeutic 131I dosages. A standard ion chamber survey meter, placed over the left upper quadrant of the abdomen, monitored orogastric transit. Each subject had ample wate...
BACKGROUND Most public transit users walk to and from transit. We analyzed the relationship between transit commuting and objectively measured physical activity. METHODS Adults aged 20 to 65 working outside the home (n = 1237) were randomly selected from neighborhoods in Seattle and Baltimore regions. Neighborhoods had high or low median income and high or low mean walkability. Mean daily min...
The wireless motility/pH capsule (WMC) is an orally ingested, nondigestible, data recording device that enables the simultaneous assessment of regional and whole gut transit. Approved by the US Food and Drug Administration for the evaluation of patients with suspected delayed gastric emptying and the evaluation of colonic transit time in patients with chronic idiopathic constipation, this capsu...
CONTEXT Esophageal dysphagia is the sensation that the ingested material has a slow transit or blockage in its normal passage to the stomach. It is not always associated with motility or transit alterations. OBJECTIVES To evaluate in normal volunteers the possibility of perception of bolus transit through the esophagus after swallows of liquid and solid boluses, the differences in esophageal ...
