To Actively Initialize Active Learning

Pattern Recognition, 2022
Though much effort has been spent on designing new active learning algorithms, little attention has been paid to the initialization problem of active learning, i.e., how to find a set of labeled samples which contains at least one instance per category. This work identifies the initialization of active learning as a separate and novel research problem,

Active packaging with antifungal activities

International Journal of Food Microbiology, 2016
There have been many reviews concerned with antimicrobial food packaging, and with the use of antifungal compounds, but none provided an exhaustive picture of the applications of active packaging to control fungal spoilage. Very recently, many studies have been done in these fields, therefore it is timely to review this topic. This article examines the

Activation of macrophages for antimycobacterial activity

Immunology Letters, 1985
The role of macrophage hydrogen peroxide in defense against mycobacterial infection is discussed - not because this is necessarily any more important than other macrophage products (reviews: [1, 2]) but more as a reflection of recently available information.

Apoptotic Caspase Activation and Activity

2008
Caspases are central to the execution of apoptosis. Their proteolytic activity is responsible for the demise of cells in many physiological and pathological states. Great advances in understanding caspases have been made using recombinant caspase expression and enzymatic characterization.

Activity—From Action to Activity

Scandinavian Journal of Caring Sciences, 1995
In this article, existing terminology concerning occupational performance is reviewed. The authors conclude that the occupational therapy terminology available is insufficient to describe levels of complexity in the performance of an activity. Concepts are suggested to describe the different aspects of an activity, namely operations, single actions ...

The Active Reader: What is Active?

Journal of Technical Writing and Communication, 2012
How writers can adapt to their readers is an important issue in effective communication strategies, and certainly crucial in the case of functional texts. Therefore, it is necessary to look at how readers are constructed as partners in a communication co-production.

Procoagulant Activity of Activated Monocytes

Haemostasis, 2009
Endotoxin-stimulated monocytes develop a very high tissue-factor-like activity as compared to an equivalent number of monocytes in a preparation of monocyte-enriched mononuclear blood cells obtained by Ficoll®-Urovison® density gradient centrifugation which is not exposed to endotoxin.

Active membranes for active transport

Journal of Theoretical Biology, 1967
Abstract A model is proposed wherein membrane subunit ingestion accounts for observed membrane function in active transport. Biological significance is given to the known rapid rate of synthesis of cell membranes, the role of calcium ion in providing membrane elasticity and binding energy for the membrane.

To activate or not to activate

Journal of Intellectual Disability Research, 2016
Aim: Motor activation of persons with profound intellectual and multiple disabilities (PIMD) in daily practice is rather limited, notwithstanding the obvious benefit. Given the needs of people with PIMD, direct support persons are to a great extent responsible for including motor activation in their daily work routine.
