Directed evolution of split APEX peroxidase
APEX is an engineered peroxidase that catalyzes the oxidation of a wide range of substrates, facilitating its use in a variety of applications, from subcellular staining for electron microscopy to proximity biotinylation for spatially restricted proteomics and transcriptomics. While this strategy …

S*: Geometric Multimodal Trajectory Optimization via Apex Interpolating Spiro Splines
… vehicles in dynamic environments that uses apex interpolating Spiro splines to optimize orders of magnitude fewer variables than numerical optimization, and (ii) an anytime best-first multimodal variant of S* using a parallel optimistic branch-and-bound on homology classes. We demonstrate a …

Snow Accumulation in the Niaqunguk (Apex) River Watershed near Iqualuit, Nunavut, Canada
Spring snowmelt is the largest input to Arctic hydrological systems. The spring snow distribution is extremely spatially variable and difficult to quantify. This study used field measurements and models to characterize and quantify the spring snow distribution in the 52 km2 Niaqunguk River …

Three-dimensional modeling of sealing and wear of XTS-210 engine Apex seals
Rotary engines offer a compact, lightweight alternative to conventional reciprocating engines, with advantages such as high power density and fewer moving parts. However, traditional rotary engines such as the Wankel have drawbacks such as excessive seal wear, combustion gas leaks and limited …

Ecosystem Functional Consequences Of Body Size Variation In An Apex Predator (Ambystoma jeffersonianum)
… (a functional trait in many aquatic taxa) in an apex predator on ecosystem functioning. We sought to characterize trophic cascades initiated by larval populations of Ambystoma jeffersonianum that varied in size structure based on diversity of maternal lines (i.e., sibship diversity) by …

Behavioural causes and consequences of sexual size dimorphism in an apex predator species.
Individual differences within populations in a range of phenotypic traits are hypothesised to have important ecological and evolutionary implications. Variation in individual growth rates that result in corresponding variations in body sizes, including size dimorphism, is a particularly widespread …

Modeling salt movement and halophytic crop growth on marginal lands with the APEX model
… Agricultural Policy/Environmental Extender (APEX) model was adapted to simulate the growth of the facultative halophyte quinoa (Chenopodium quinoa), along with salt dynamics in the plant-soil-water system. Modifications to the model included salt uptake and salt stress functions that were …

An In Vitro Evaluation of the Elements Apex Locator Using the Endo Q System
… 1) to determine the accuracy of the Elements Apex Locator and 2) to compare the accuracy of the alginate and Endo Q models as in-vitro apex locator testing devices. Twenty teeth were decoronated at the CEJ and triplicate measurements were made using the Elements Apex Locator. All measurements …

Gazing at Other Animals: A Deconstruction of the Anthropocentric Gaze in the Representation of Apex Predators
… research deconstructs representations of large apex predator animals within film and wildlife documentaries, examining the influence of mainstream narratives on public perceptions of wildlife behaviour. Through the cultural studies field of Critical Animal Media Studies (CAMS), the research …

Judicial activism in the UK and Ireland, with particular reference to Apex Courts and human rights
This LLD thesis comprises a collection of three monographs, two edited books, ten journal articles and eight book chapters, all published between 2006 and 2020. As explained in the initial Summary document, they represent a body of work on the topic of judicial activism within the United Kingdom …

A survey of characteristics and attitudes of offices currently and previously participating in the APEX program
… is the Applied Professional Experience Program (APEX.) The APEX Program, the first of its kind in dental education, allows students to alternate between the classroom and clinical studies, and dental clerkships in Boston area dental practices. The APEX Program enables dental students to function …

Space Use and Survival of White-Tailed Deer in a Disturbance-Driven System Containing a Restored Apex Predator
White-tailed deer (Odocoileus virginianus) in the Big Cypress Basin of South Florida must cope with top-down and bottom-up forces, including frequent pyrogenic and hydrological disturbances and the threat of predation. These forces affect their space use, behavior, and survival. Recent changes to …

Landscape dynamics from 1990--2010 and the human to apex predator (red-tailed hawk) relationship on La Gonave, Haiti
The island of La Gonave, ~50 km northwest of Port-au-Prince, represents the subsistence Haitian lifestyle. Little is known about human--environment interactions on La Gonave. The first objective of this research was to investigate landscape dynamics through image classification, change detection, …

In Vitro Precision of the E-PEX Electronic Apex Locator Compared to the Root ZX II in Various Embedding Media
… obturation. The development of the Electronic Apex Locator (EAL) has helped the clinician to determine the location of the apical foramen, and hence the working length, when performing NSRCT. Objectives: The goal of this study is to determine the accuracy of a new EAL, the E-PEX, and compare it …

Behavioural ecology of white sharks carcharodon carcharias in False Bay, South Africa: towards improved management and conservation of a threatened apex predator
The coastal waters off South Africa support a significant proportion of the global white shark population, with at least four well-established coastal aggregation sites. How critical these sites are to the southern African and hence global white shark population depends to a large extent, on their …
