Oregon grape growers are sometimes troubled with fruit set problems. There are many types of fruit set disorders, but a recently described one is inflorescence necrosis (IN). Though many studies related to the disorder have been done at OSU and elsewhere, investigation into IN is still in its infancy. Several...
Poor set and low yields in 1988 and 1990 were, in part, attributed to Inflorescence Necrosis (IN), a disorder that results in death of flowers and rachis tissue near bloom-time. In isolated areas, IN has caused significant loss of crop in each year since then. Past research at OSU has...
Heavy metals have historically been popular for use in cosmetics manufacturing due to the colorful pigmentation of heavy metal compounds. In the case of sindoor, a cosmetic used by married Hindu women for religious purposes, mercury sulfide, lead tetroxide, and lead chromate are compounds suspected to still be involved in...
The need for clean energy continues to rise as the earth’s non-renewable resources continue to be depleted to satisfy energy demands. One plausible renewable energy source exists in biomass-powered fuel cells.¹ While there are several ways to convert sugars to energy, one interesting approach is to convert the sugars to...
Tanoak (Lithocarpus densiflorus), along with some other members of Fagaceae, are susceptible to sudden oak death caused by the oomycete Phytophthora ramorum. Symptoms of the disease include dying crowns, bleeding cankers, and eventually death of infected trees. The cause of mortality is not well understood, but recent research indicates that...
Boyd and Walter (1975) identified the need to provide supervision for school counselors almost forty years ago. Michelle Obama, the First Lady of the United States (2014), in her address at the American School Counselor Association Conference stated that school counselors needed to be provided with professional development opportunities designed...
This work presents improvements to a multi-core performance/power simulator. The improvements which include updated power models, voltage scaling aware models, and an application specific benchmark, are done to increase the accuracy of power models under voltage and frequency scaling. Improvements to the simulator enable more accurate design space exploration for...
Endogenous circadian clock regulation is essential to normal rhythmicity, particularly the timing of hormone release in the brain. In the context of mammalian reproduction, a surge of a specific hormone, gonadotrophin-releasing hormone (GnRH), initiates a surge of luteinizing hormone (LH) from the pituitary gland, which is required for ovulation in...
Riparian zones of Pacific Northwest forests have high species diversity and abundance and act as an important interface between the aquatic and terrestrial ecosystems. In addition, riparian zones comprise a significant portion of the total buffer zone established during commercial forest production to protect aquatic ecosystems from adjacent management activities....

Predicting the average affect of a piece of music is a task which has been of recent interest in the field of music information retrieval. We investigate the use of sentiment analysis on online social media conversations to predict a song’s valence and arousal. Using four music emotion datasets -...
