The global network of marine protected areas: developing baselines and identifying priorities
Recently adopted global marine protection targets aim to protect 10-30% of marine habitats within the next 3 to 5 years. However, these targets were adopted without prior assessment of their attainability. Moreover, our ability to monitor progress towards such targets has been constrained by a lack …

Resetting marine environmental baselines for the United Kingdom: what have we really lost?
… offer another way of establishing environmental baselines. However, these areas are often used for non-consumptive activities which may also negatively impact upon habitats and wildlife if inadequately managed. An examination of 91 HPMRs from around the world show that many permit potentially …

Establishing genetic and physiological baselines for the black-tailed prairie dog (Cynomys ludovicianus).
… other similar but genetically distinct colonies. Baselines for healthy, pet prairie dog hematology and blood chemistries were also established. Results signify that data gathered from pet prairie dog blood analyses should be referenced against hematology and blood chemistry baselines established …

Historical baselines and a century of change in the demersal fish assemblages on South Africa's Agulhas Bank
… of current abundances relative to pre-disturbed baselines at those sites, which c) highlights drastic local depletion for certain taxa and d) reveals substantial abundance increases of certain species during the post-industrial fishing period; e) novel evidence of distribution trends in south …

Arsenic mobility in a changing northern climate: Implications for geochemical baselines and long-term stability of contaminants in lake systems
Climate change is influencing the biogeochemical dynamics of lake systems in northern Canada. These changes may affect the loading and cycling of naturally occurring metal(loid)s and the long-term stability of mining-derived contaminants in sub-Arctic lakes. Arsenic (As) concentrations of lakes in …

Supporting Aspiring Teachers: The Study of Teacher Certification Pathways, Influencing Factors, and Preservice Baselines to Develop the Certification Pathway and Program Selection Tool
… EPP, and how certification seekers’ pre-service baselines (knowledge, experiences, dispositions, and goals) support them in their certification journey. Methods: A survey was administered to individuals enrolled in a Texas EPP between 2018 and 2022. The survey asked participants to share their …

Investigation of refraction effects for small GPS networks
… are considered. The repeatability of individual baselines and 3-D vector closures are examined, in order to investigate refraction effects on GPS networks. The effect on GPS baselines of a height bias in the reference point's coordinates is also investigated. A least squares adjustment program is …

Long-Term Stability of Baseline Impact Scores in High School Football Players across Age Groups
… the ages of 14 and 17 who had completed two baselines one year apart were selected from a de-identified archival database. Subjects were separated into three groups based on age at first baseline (i.e., 14, 15, and 16). Results indicate differences in baseline performance stability between …

EVALUATING THE PERFORMANCE OF BIOMETRIC APPROACHES FOR VERIFICATION AND MONITORING IN COMMERCIAL FOREST CARBON ACCOUNTING
… allometric models. However, stock-centric carbon baselines fail to capture all carbon sources and sinks, and dynamic meteorological conditions drive carbon uptake and forest growth. A combination of high temporal and spatial resolution monitoring of land-atmosphere carbon fluxes (flux towers) and …

A Bayesian model for dynamic functional connectivity estimation in the human brain with structural priors
… Finally, it outperformed sliding window baselines and anatomically un-informed baselines on estimating instantaneous covariances according to out-of-sample log likelihood on two task datasets.

The MeerKAT Radio Frequency Interference Environment
… the phase of the RFI changes rapidly on long baselines compared to short baselines. As a result when a correlation is carried out the RFI amplitude will vanish less on short baselines compared to the long baselines. Our results provide the first highly detailed view of the MeerKAT RFI …

Implementation of stereo correspondence algorithms for multi-baseline vision system
… is to determine the impact of varying camera baselines on correspondence and depth estimation. As the baseline increases the resolution of depth increases but finding correspondences is very tedious. On the other hand when cameras are placed close to each other and thereby reducing the …

Establishing a baseline for evaluating changes in fish body condition and population dynamics of Cape hake (Merluccius capensis and M. paradoxus) in South Africa
… Cape hake. The aim was to provide fixed baselines and Wr indices to aid understanding of temporal and spatial variability in fish condition . Baselines were calculated using the empirical percentiles (EmP) method applied to length (L) – weight (W) data collected by research surveys on the …

Sterile neutrinos in cold climates
Measurements of neutrino oscillations at short baselines contain an intriguing set of experimental anomalies that may be suggestive of new physics such as the existence of sterile neutrinos. This three-part thesis presents research directed towards understanding these anomalies and searching for …

Scalability and interpretability of graph neural networks for small molecules
… performance with common graph neural network baselines. I also show that the network is capable of learning features that allow for transfer learning to larger molecules with significantly better performance than some baselines. This provides evidence the network is learning chemically useful …

SparkSim: A Counterfactual Approach for Spark Cluster Scheduling
… of SparkSim. We evaluate SparkSim on two baselines that do not require training. Our results show that SparkSim underperforms against these baselines during easier prediction tasks (such as copying from source), but outperforms them when the prediction tasks get harder. Future work lends …
