The objective is to understand how sterol transport is affected by caloric restriction (CR) and aging. Sterol synthesis generally increases as cells age. Yet, despite this increase, the sterol content of selected organelle membranes, such as lysosomal membranes, declines with age and adversely affects cellular functions. We are interested in a better understanding of changes in sterol transport to membranes of vacuoles (the yeast counterparts of mammalian lysosomes) in response to anti-aging and pro-aging manipulations.

Stemming is the process of reducing words to their stems or roots. Due to the morphological richness and complexity of the Arabic language, stemming is an essential part of most Natural Language Processing (NLP) tasks for this language. In this paper, we study the impact of different stemming approaches on the Named Entity Recognition (NER) task for Arabic and explore the merits, limitations and differences between light stemming and root-extraction methods. Our experiments are evaluated on the standard ANERCorp dataset as well as the AQMAR Arabic Wikipedia Named Entity Corpus.
