Under which conditions could a column increase the flow through an exit? A simulation study [PDF]

open access: yesEPJ Web of Conferences
Empirical studies in the past have produced different results about whether an obstacle placed in front of a bottleneck can increase the flow of pedestrians through the bottleneck. Here, simulations are used to try to determine the conditions under which

Identification of a novel porcine Teschovirus 2 strain as causative agent of encephalomyelitis in suckling piglets with high mortality in China

open access: yesBMC Veterinary Research, 2023
Background Porcine Teschovirus (PTV), also named Teschovirus A, is prevalent in pig populations, mainly causing neurological symptoms, diarrhea, pneumonia, and reproductive failure, however the morbidity and mortality are usually low in pig farms.

The power of many: when genetics met yeasts and high‐throughput

open access: yesBiological Reviews, EarlyView.
ABSTRACT In recent years, complex technological capabilities have evolved, driven by the need to solve complex and integrative biological questions through global analyses. New equipment allows the scaling up and automation of processes which previously were carried out on a very limited scale.

Gradual Colonic Impaction of a Chicken Bone Associated with Inflammatory Pseudotumor Formation and Nonocclusive Colon Ischemia

open access: yesCase Reports in Radiology, 2014
Foreign body (FB) ingestion is a common clinical problem and most FBs pass through the gastrointestinal tract without the need for intervention. A wide spectrum of clinical presentations may be possible and these can be either acute or chronic.

Analysis of binary spatial data by quasi-likelihood estimating equations

open access: yes, 2005
The goal of this paper is to describe the application of quasi-likelihood estimating equations for spatially correlated binary data. In this paper, a logistic function is used to model the marginal probability of binary responses in terms of parameters ...

Dosimetric comparison study between intensity modulated radiation therapy and three-dimensional conformal proton therapy for pelvic bone marrow sparing in the treatment of cervical cancer. [PDF]

open access: yes, 2010
The objective was to compare intensity-modulated radiation therapy (IMRT) with 3D conformal proton therapy (3DCPT) in the treatment of cervical cancer. In particular, each technique's ability to spare pelvic bone marrow (PBM) was of primary interest in ...

Junctioning longitudinally adjacent PTVs with Helical TomoTherapy [PDF]

open access: yesJournal of Applied Clinical Medical Physics, 2010
Irradiation of longitudinally adjacent PTVs with Helical TomoTherapy (HT) may be clinically necessary, for example in treating a recurrent PTV adjacent to a previously‐treated volume. In this work, the parameters which influence the cumulative dose distribution resulting from treating longitudinally adjacent PTVs are examined, including field width ...
