Soil carbon dioxide (CO2) flux, or soil respiration, is a critical control on net ecosystem carbon (C) balance. Using long-term (2002-2020) measurements at the Hubbard Brook Experimental Forest (New Hampshire, U.S.), we show that soil respiration rates have notably increased since ~2015. In 2020, cumulative summer respiration flux was approximately 90% higher than the average summer flux over the 2002–2015 period. The increase in soil respiration cannot be explained directly by temperature or pH change alone. We also found that heterotrophic microbial C mineralization and microbial biomass C have also increased rapidly since ~2015, pointing towards an increase in the …

A Review On The Cytogenetic Integrity Of Micropropagated Plants [Review Paper], Eliaza Alumbro Peniton Jr

The Philippine Agricultural Scientist

Cytogenetic stability is essential for the survival of micropropagated plants. While micropropagation allows rapid propagation of plants with desirable phenotypes, it may also produce genetic variations that are, at times, cytogenetically observable. Factors affecting these variations are not fully understood, and micropropagation protocols are optimized to produce genetically stable regenerants. The genetic stability of micropropagated plants is traditionally assessed by comparing the phenomorphological traits of the regenerants to the mother plant. However, genetic variation does not often result in obvious morphological changes. Therefore, molecular and cytogenetic markers are typically used to evaluate the genetic variations of regenerants. Moreover, analyzing plant …

A Case Study Of Leveraging Auxiliary Data To Improve Treatment Effect Estimation Precision In An Hiv Clinical Trial, Lana Mai Huynh

Master's Theses

Randomized controlled trials (RCTs) are typically the gold standard for evaluating treatment efficacy in the medical field, yet they can have small sample sizes due to logistical, ethical, and financial constraints. This limitation can result in imprecise treatment effect estimates. Recent methods have sought to enhance the precision of RCT estimates by incorporating information from large, observational, “auxiliary” datasets. An auxiliary dataset includes units that were not randomized in the trial itself, but may be similar to the RCT sample. By leveraging predictive models trained on these auxiliary data, researchers can adjust for potentially more powerful covariates, thereby reducing variance …

Catalyzed Chemical Recycling Of Poly(Ethylene Terephthalate) For Enhanced Sustainability, Gilberto J. Hernandez-Leypon Jr.

Master's Theses

Plastics are ubiquitous in the production of consumer and industrial products; their chemical stability, low cost of production, and performance versatility make them the best option for many industries. Their inherent benefits, specifically durability, is the basis for the negative environmental impact of polymers.
