Continuous-time open quantum walks in one dimension: matrix-valued orthogonal polynomials and Lindblad generators [PDF]

open access: yes, 2023
We study continuous-time open quantum walks in one dimension through a matrix representation, focusing on nearest-neighbor transitions for which an associated weight matrix exists. Statistics such as site recurrence are studied in terms of matrix-valued orthogonal polynomials and explicit calculations are obtained for classes of Lindblad generators ...

A small footprint couch‐top support device for image‐guided radiotherapy of heavy patients

open access: yesJournal of Applied Clinical Medical Physics, Volume 23, Issue 12, December 2022., 2022
Abstract Purpose Patients with body weights close to or above 400 lbs present unique challenges in radiation therapy since the weight limit of most treatment couches decreases as the couch‐top extends toward the treatment gantry. The purpose of this work was to develop a small footprint couch‐top support platform to safely perform image‐guided ...

Amazon Forest Fires Between 2001 and 2006 and Birth Weight in Porto Velho [PDF]

open access: yesBulletin of Environmental Contamination and Toxicology, July 2012, Volume 89, Issue 1, pp 1-7, 2019
Birth weight data (22,012 live-births) from a public hospital in Porto Velho (Amazon) was used in multiple statistical models to assess the effects of forest-fire smoke on human reproductive outcome. Mean birth weights for girls (3,139 g) and boys (3,393 g) were considered statistically different (p-value < 2.2e-16).

Micronutrient Intake and Fundal Height Determine Birth Weight [PDF]

open access: yes, 2019
The birth weight (BW) are utilized as indicators of the healthy and term newborns. Factor that affects the weight of a newborn are micronutrient intake and fundal height. Folic acid and iron (Fe) were associated with newborn birth weight.

Image quality comparisons of coil setups in 3T MRI for brain and head and neck radiotherapy simulations

open access: yesJournal of Applied Clinical Medical Physics, Volume 23, Issue 12, December 2022., 2022
Abstract Purpose MRI is increasingly used for brain and head and neck radiotherapy treatment planning due to its superior soft tissue contrast. Flexible array coils can be arranged to encompass treatment immobilization devices, which do not fit in diagnostic head/neck coils. Selecting a flexible coil arrangement to replace a diagnostic coil should rely
