Non-contact hemodynamic imaging reveals the jugular venous pulse waveform [PDF]
arXiv, 2016 Cardiovascular monitoring is important to prevent diseases from progressing. The jugular venous pulse (JVP) waveform offers important clinical information about cardiac health, but is not routinely examined due to its invasive catheterisation procedure.

Microsurgery, 2018 Venous congestion is the principle cause of flap failure after microsurgical breast reconstruction. We aim to correlate preoperative computed tomography angiography (CTA) findings with postoperative venous congestion to predict patients at risk of ...

Paraspinal arterio-venous fistula in children: two more cases of an exceptional malformation
Clinics and Practice, 2015 We report on the case of two toddlers who presented in the last 2 years with heart and vascular murmur, respectively, and in whom the diagnosis of paraspinal arterio-venous fistula was made.

Congestion Avoidance in Computer Networks with a Connectionless Network Layer, Part I: Concepts, Goals and Methodology [PDF]
arXiv, 1998 Congestion is said to occur in the network when the resource demands exceed the capacity and packets are lost due to too much queuing in the network. During congestion, the network throughput may drop to zero and the path delay may become very high. A congestion control scheme helps the network to recover from the congestion state.

A Multilevel Network-assisted Congestion Feedback Mechanism for Network Congestion Control [PDF]
Computers and Electrical Engineering 2025Network-assisted congestion control leveraging Explicit Congestion Notification (ECN) is an effective way to deal with congestion issues on the Internet. However, we believe that the existing ECN mechanism in the TCP/IP protocol stack may require further optimization to effectively address the evolving congestion challenges introduced by emerging ...

Scientific Reports, 2018 Venous congestion is an important contributor to worsening renal function in heart failure and the cardiorenal syndrome. In patients, it is difficult to study the effects of isolated venous congestion on organ function. In this study, the consequences of

Effective Road Model for Congestion Control in VANETs [PDF]
arXiv, 2016 Congestion on the roads is a key problem to deal with, which wastes valuable time.. Due to high mobility rate and relative speed link failure occur very often. VANET is used to tackle the problem of congestion, and make decisions well in advance to avoid traffic congestion.

Selective abdominal venous congestion to investigate cardiorenal interactions in a rat model
PLoS ONE, 2018 Abdominal congestion may play an important role in the cardiorenal syndrome and has been demonstrated to drive disease progression. An animal model for abdominal congestion, without other culprit mechanisms that are often present in patients such as low ...

Pelvic congestion syndrome due to agenesis of the infrarenal inferior vena cava
Radiology Case Reports, 2019 The inferior vena cava (IVC) is the main conduit of venous return to the right atrium from the lower extremities and abdominal organs. Agenesis of the IVC has an incidence of

Mechanical Leeching with Venocutaneous Fistula and Monitoring with Near-infrared Spectroscopy
Plastic and Reconstructive Surgery, Global Open, 2013 Summary: The report herein describes the use of a venocutaneous fistula with angiocatheter attachment and near-infrared spectroscopy device to correct venous congestion of a vertical upper gracilis free flap used for breast reconstruction. This method of
