Global desertification vulnerability to climate change and human activities

Land Degradation and Development, 2020
Desertification is the impoverishment of arid, semiarid, and some subhumid ecosystems. The assessment of global scale desertification vulnerability to climate change and human activity is important to help decision makers formulate the best strategies ...

FIBRINOLYTIC ACTIVATOR ACTIVITY IN HUMAN NEOPLASMS

Plastic and Reconstructive Surgery, 1978
The results of this study suggest that many malignant tumors contain low levels of fibrinolytic activator activity. Evidence is presented to suggest that this low activity may be due to the presence of an inhibitor of fibrinolysis. The presence or absence of measurable fibrinolytic activator activity, and/or inhibitor in neoplastic growths may enable ...

Human Activities Classification Based on Complex-Value Convolutional Neural Network

IEEE Sensors Journal, 2020
The classification and recognition of human activities plays an important role in the fields of security, crime prevention, medical surveillance, etc. The swings of the limbs during the movement of the human body introduce rich micro-Doppler information.

Deep convolutional autoencoder for radar-based classification of similar aided and unaided human activities

IEEE Transactions on Aerospace and Electronic Systems, 2018
Radar-based activity recognition is a problem that has been of great interest due to applications such as border control and security, pedestrian identification for automotive safety, and remote health monitoring. This paper seeks to show the efficacy of

Human Neutrophil Antimicrobial Activity

Clinical Infectious Diseases, 1988
Polymorphonuclear neutrophilic leukocytes (PMNs) take up opsonized microorganisms into phagosomes that fuse with secretory granules in the PMN cytoplasm to form phagolysosomes. Killing and digestion of microorganisms take place within phagolysosomes. Antimicrobial activities in phagolysosomes are divided into two classes.
