Progressive or degressive compression pressure profile in patients with chronic venous disorders of the lower limb

open access: yesVeins and Lymphatics, 2014
Graduated compression devices are considered the standard care for management of venous and lymphatic disorders. Recently compression devices exerting a pressure over the calf higher than over the ankle have been proved to be more effective than ...

Using the Semantic Information G Measure to Explain and Extend Rate-Distortion Functions and Maximum Entropy Distributions

open access: yesEntropy, 2021
In the rate-distortion function and the Maximum Entropy (ME) method, Minimum Mutual Information (MMI) distributions and ME distributions are expressed by Bayes-like formulas, including Negative Exponential Functions (NEFs) and partition functions. Why do

Compressing Functional Tests for Microprocessors [PDF]

open access: yes14th Asian Test Symposium (ATS'05), 2005
In the past, test data volume reduction techniques have concentrated heavily on scan test data content. However, functional vectors continue to be utilized because they target unique defects and failure modes. Hence, functional vector compression can help alleviate the cost of functional test. Scan vector compression techniques are generally unsuitable

Utility of Computed Tomography Surveillance of Asymptomatic Infection in Children and Young Adults Before Allogeneic Hematopoietic Stem Cell Transplant

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Asymptomatic infection poses a significant risk for children undergoing hematopoietic stem cell transplantation (HSCT). Pre‐transplant surveillance computed tomography (CT) is commonly used to identify occult infection, though its diagnostic yield remains uncertain.
