Variable Selection in High-dimensional Varying-coefficient Models with Global Optimality

Creator:: Xue, Lan and Qu, Annie
Abstract:: The varying-coefficient model is flexible and powerful for modeling the dynamic changes of regression coefficients. It is important to identify significant covariates associated with response variables, especially for high-dimensional settings where the number of covariates can be larger than the sample size. We consider model selection in the high-dimensional setting...

Known locations include the...

Abstract:: The rapid disruption of tropical forests probably imperils global biodiversity more than any other contemporary phenomenon¹⁻³. With deforestation advancing quickly, protected areas are increasingly becoming final refuges for threatened species and natural ecosystem processes. However, many protected areas in the tropics are themselves vulnerable to human encroachment and other environmental...

Proteomics-driven Antigen Discovery for Development of Vaccines Against Gonorrhea

Creator:: Zielke, Ryszard A., Wierzbicki, Igor H., Baarda, Benjamin I., Gafken, Philip R., Soge, Olusegun O., Holmes, King K., Jerse, Ann E., Unemo, Magnus, and Sikora, Aleksandra E.
Abstract:: Expanding efforts to develop preventive gonorrhea vaccines is critical because of the dire possibility of untreatable gonococcal infections. Reverse vaccinology, which includes genome and proteome mining, has proven very successful in the discovery of vaccine candidates against many pathogenic bacteria. However, progress with this approach for a gonorrhea vaccine remains...

Landscape characteristics and coho salmon (Oncorhynchus kisutch) distributions: explaining abundance versus occupancy

Creator:: Steel, E. A., Jensen, D. W., Burnett, K. M., Christiansen, K., Firman, J. C., Feist, B. E., Anlauf, K. J., and Larsen, D. P.
Abstract:: Distribution of fishes, both occupancy and abundance, is often correlated with landscape-scale characteristics (e.g., geology, climate, and human disturbance). Understanding these relationships is essential for effective conservation of depressed populations. We used landscape characteristics to explain the distribution of coho salmon (Oncorhynchus kisutch) in the Oregon Plan data set, one...

Abstract:: Several evolutionarily significant units (ESUs) of Columbia River basin Chinook Salmon Oncorhynchus tshawytscha and Coho Salmon O. kisutch are listed as threatened or endangered under the U.S. Endangered Species Act. Yet little is known about the spatial and temporal distributions of these ESUs immediately following ocean entry, when year-class success...

Abstract:: For the past six years in which overwintering mortality of honey bee colonies has been surveyed in the USA, estimates of colony loss have fluctuated around one-third of the national population. Here we report on the losses for the 2012-2013 seasons. We collected data from 6,482 US beekeepers (6,114 backyard,...

On the temporal upscaling of evapotranspiration from instantaneous remote sensing measurements to 8-day mean daily-sums

Abstract:: The regular monitoring of evapotranspiration from satellites has been limited because of discontinuous temporal coverage, resulting in snapshots at a particular point in space and time. We developed a temporal upscaling scheme using satellite-derived instantaneous estimates of evapotranspiration to produce a daily-sum evapotranspiration averaged over an 8-day interval. We tested...

Brion, Keane, John J., Franklin, Jerry F., and Riegel, Greg
Abstract:: Increasingly, objectives for forests with moderate- or mixed-severity fire regimes are to restore successionally diverse landscapes that are resistant and resilient to current and future stressors. Maintaining native species and characteristic processes requires this successional diversity, but methods to achieve it are poorly explained in the literature. In the Inland...

Differential growth rates through the seedling and sapling stages of two Nothofagus species underplanted at low-light environments in an Andean high-graded forest

Creator:: Donoso, Pablo J., Soto, Daniel P., and Fuentes, Claudio
Abstract:: The Andes of south-central Chile, with the valuable and dominant timber species Nothofagus dombeyi and N. alpina, have been heavily high-graded. Restoring these high-graded forests with these species is challenging since they are light demanding and the understory becomes dominated by bamboo (Chusquea culeou), which prevents natural regeneration. In this...
