Motion of discrete interfaces in low-contrast periodic media

, 2014
We study the motion of discrete interfaces driven by ferromagnetic interactions in a two-dimensional low-contrast periodic environment, by coupling the minimizing movements approach by Almgren, Taylor and Wang and a discrete-to-continuum analysis.

Intravenous contrast media optimization at computed tomography [PDF]

, 2015
The administration of intravenous contrast media (IV CM) is essential for detecting lesions at most computed tomography (CT) examinations. The overall aim of this thesis is to investigate different aspects of IV CM administration that may affect the ...

Hypertension, renal failure, and edema in a 38-year-old man: light chain deposition disease; a case report and review of the literature [PDF]

Journal of Nephropathology, 2014
Background: Monoclonal immunoglobulin deposition disease (MIDD) is a rare disease, usually manifesting between the 5th and 6th decades of life but can also occur earlier. Characteristic feature of MIDD is a non-fibrillar, Congo red negative deposition of

The unpredictably eruptive dynamics of spruce budworm populations in eastern Canada

Population Ecology, EarlyView.
We examine historical population data for spruce budworm from several locations through the period 1930–1997, and use density‐dependent recruitment curves to test whether the pattern of population growth over time is more consistent with Royama's (1984; Ecological Monographs 54:429–462) linear R(t) model of harmonic oscillation at Green River New ...

Recurrent neck swelling after iodinated contrast media administration

Radiology Case Reports, 2021
A 74-year-old male with an abdominal aortic aneurism reported 2 episodes of neck swelling 16 hours after an abdominal CT with iodinated contrast media that reappeared in a subsequent CT, although the use of pre-medication.

Network topology drives population temporal variability in experimental habitat networks

Population Ecology, EarlyView.
Habitat patches connected by dispersal pathways form habitat networks. We explored how network topology affects population outcomes in laboratory experiments using a model species (Daphnia carinata). Central habitat nodes in complex lattice networks exhibited lower temporal variability in population sizes, suggesting they support more stable ...

Pharmacist-led iodinated contrast media infusion risk assessment service

Frontiers in Pharmacology, 2023
Background: With the increasing development of medical imaging, the use of iodinated contrast media has become more widespread. Adverse reactions caused by iodinated contrast media have drawn much attention. Despite this, there is still a lack of unified

Contrast of a Quality Control Model for Sustainability in a Mexican Organization in Central Mexico [PDF]

, 2017
Often, the total quality has been instrumented before being weighted. The strategies even precede a diagnosis in Mexican organizations, but in an opposite sense, the present work set out to establish the reliability and validity of an instrument to ...

Between Droughts and Floods: The Seasonal Response of Freshwater Snails in Artificial Reservoirs in the Brazilian Semiarid Region

Population Ecology, EarlyView.
We investigate the seasonal dynamics of two freshwater snails, Biomphalaria straminea and Melanoides tuberculata, in artificial reservoirs of the Brazilian semiarid region. Despite regulated hydrology, B. straminea exhibited strong seasonal fluctuations associated with dry periods, while M. tuberculata maintained stable populations throughout the year,
