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.

A Proposal of Image Sensors for PTV

open access: yesJournal of the Visualization Society of Japan, 1999
PTV( Particle Tracking Velocimetry) is applied to images with moving particle images. Properties required for image sensors to analyze movements of scattered particles are discussed. Much higher frame rate than 30 pps is essential, which is realized by parallel readout architecture.

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 ...

Hypervision Proton Surgery: The Future Direction of Proton Therapy

open access: yesiNew Medicine, EarlyView.
ABSTRACT Proton beams provide unique physical advantages characterized by a low entrance dose, negligible exit dose, and a sharp Bragg peak, which enable superior sparing of normal tissues and support safe dose escalation for improved tumor control. However, conventional photon‐based fractionation remains widely used in proton therapy, where prolonged ...

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.

A Highly Conserved Epitope (RNNQIPQDF) of Porcine teschovirus Induced a Group-Specific Antiserum: A Bioinformatics-Predicted Model with Pan-PTV Potential

open access: yesViruses, 2020
Porcine teschovirus (PTV) is an OIE-listed pathogen with 13 known PTV serotypes. Heterologous PTV serotypes frequently co-circulate and co-infect with another swine pathogen, causing various symptoms in all age groups, thus highlighting the need for a ...

Congenital kidney malformation: Computed tomography and scintigraphy findings of renal reversed rotation

open access: yesRadiology Case Reports, 2019
Renal reversed rotation is a congenital abnormality due to anomalous kidney rotation around its long axis, resulting in faced laterally renal hilum; this condition is associated with several vascular variants.
