Memorandum of Amici Curiae Doug Rendleman & Caprice Roberts in Support of Plaintiff: \u3cem\u3eEstate of Henrietta Lacks v. Thermo Fisher Scientific\u3c/em\u3e
This brief addresses the law of unjust enrichment and its relationship to restitution has failed to state a valid cause of action for restitution relief. Defendant incorrectly insists that plaintiff must plead a tort to seek restitution remedies as well as Both arguments belie the basic tenets of unjust enrichment law. Simply, plaintiff may seek restitution remedies based either a separate tort nor an allegation of the lack of bona fide purchaser status is required to survive these challenges
Map-induced journey-planning biases for a simple network: A Docklands Light Railway study
A usability study was conducted to identify the most effective prototype Docklands Light Railway map for installation on trains. This comprised a series of tasks that required station finding and also planning of routes between pairs of stations, with response time and accuracy as measures of performance. In addition, subjective ratings of map design were collected via questionnaire-based evaluations, and also ranked preferences between designs. A clear best-option was easily identifiable as a result of this research. The existing design was associated with the most journey planning errors, and two of the prototypes were associated with inefficient journey choices. The latter finding suggested that respondents were using unsophisticated planning strategies that were put at a disadvantage by certain route depictions. This has wider implications for suggestions that schematic maps should maintain topographical relationships in order to facilitate appropriate journey choices, with the danger that the inevitable increased complexity of line trajectories for such designs would simultaneously reduce the ability of passengers to identify the most appropriate routes
Towards flow cytometry data clustering on graphics processing units
Like many modern techniques for scientific analysis, flow cytometry produces massive amounts of data that must be analyzed and clustered intelligently to be useful. Current manual binning techniques are cumbersome and limited in both the quality and quantity of analyses produced. To address the quality of results, a new framework applying two different sets of clustering algorithms and inference methods are implemented. The two methods investigated are fuzzy c-means and minimum description length inference and k-medoids with BIC. These approaches lend themselves to large scale parallel processing. To address the computational demands, the Nvidia CUDA framework and Tesla architecture are utilized. The resulting performance demonstrated 1-2 orders of magnitude improvement over an equivalent sequential version. The quality of results is promising and motivates further research and development in this direction
Using Artificial Populations to Study Psychological Phenomena in Neural Models
The recent proliferation of research into transformer based natural language
processing has led to a number of studies which attempt to detect the presence
of human-like cognitive behavior in the models. We contend that, as is true of
human psychology, the investigation of cognitive behavior in language models
must be conducted in an appropriate population of an appropriate size for the
results to be meaningful. We leverage work in uncertainty estimation in a novel
approach to efficiently construct experimental populations. The resultant tool,
PopulationLM, has been made open source. We provide theoretical grounding in
the uncertainty estimation literature and motivation from current cognitive
work regarding language models. We discuss the methodological lessons from
other scientific communities and attempt to demonstrate their application to
two artificial population studies. Through population based experimentation we
find that language models exhibit behavior consistent with typicality effects
among categories highly represented in training. However, we find that language
models don't tend to exhibit structural priming effects. Generally, our results
show that single models tend to over estimate the presence of cognitive
behaviors in neural models
Water Integration for Squamscott Exeter (WISE): Preliminary Integrated Plan, Final Technical Report
This document introduces the goals, background and primary elements of an Integrated Plan for the Lower Exeter and Squamscott River in the Great Bay estuary in southern New Hampshire. This Plan will support management of point (wastewater treatment plant) and nonpoint sources in the communities of Exeter, Stratham and Newfields. The Plan also identifies and quantifies the advantages of the use of green infrastructure as a critical tool for nitrogen management and describes how collaboration between those communities could form the basis for an integrated plan. The Plan will help communities meet new wastewater and proposed stormwater permit requirements. Critical next steps are need before this Plan will fulfill the 2018 Nitrogen Control Plan requirements for Exeter and proposed draft MS4 requirements for both Stratham and Exeter. These next steps include conducting a financial capability assessment, development of an implementation schedule and development of a detailed implementation plan. The collaborative process used to develop this Plan was designed to provide decision makers at the local, state and federal levels with the knowledge they need to trust the Plan’s findings and recommendations, and to enable discussions between stakeholders to continue the collaborative process.
This Plan includes the following information to guide local response to new federal permit requirements for treating and discharging stormwater and wastewater: Sources of annual pollutant load quantified by type and community;
Assessment and evaluation of different treatment control strategies for each type of pollutant load;
Assessment and evaluation of nutrient control strategies designed to reduce specific types of pollutants;
Evaluation of a range of point source controls at the wastewater treatment facility based on regulatory requirements;
Costs associated with a range of potential control strategies to achieve reduction of nitrogen and other pollutants of concern; and
A preliminary implementation schedule with milestones for target load reductions using specific practices for specific land uses at points in time;
Recommendations on how to implement a tracking and accounting program to document implementation;
Design tools such as BMP performance curves for crediting the use of structural practices to support nitrogen accounting requirements; and
Next Steps for how to complete this Plan
Linkages between the Genesis and Resource Potential of Ferromanganese Deposits in the Atlantic, Pacific, and Arctic Oceans
In addition to iron and manganese, deep sea ferromanganese deposits, including nodules and crusts, contain significant amounts of economically interesting metals, such as cobalt (Co), nickel (Ni), copper (Cu), and rare Earth elements and yttrium (REY). Some of these metals are essential in the development of emerging and new-generation green technologies. However, the resource potential of these deposits is variable, and likely related to environmental conditions that prevail as they form. To better assess the environmental controls on the resource potential of ferromanganese deposits, we have undertaken a detailed study of the chemical composition of ferromanganese nodules and one crust sample from different oceanic regions. Textural and chemical characteristics of nodules from the North Atlantic and a crust from the South Pacific suggest that they acquire metals from a hydrogenous source. These deposits are potentially an economically important source of Co and the REY. On the other hand, nodules from the Pacific Ocean represent a marginal resource of these metals, due to their relatively fast growth rate caused by diagenetic precipitation. By contrast, they have relatively high concentrations of Ni and Cu. A nodule from the Arctic Ocean is characterised by the presence of significant quantities of detrital silicate material, which significantly reduces their metal resource
