Fine scale structural information substantially improves multivariate regression model for mRNA in-vial degradation prediction Open
The success of COVID-19 mRNA vaccines has made optimizing mRNAs for in-vial stability a key objective. However, we still lack a complete understanding of the sequence metrics that influence mRNA stability in solution. RNA secondary structu…

'Policing Rural Communities in North America': An International Society for the Study of Rural Crime Roundtable Open
Rural crime and criminal justice practices and responses face different challenges from those experienced in urban contexts. A practitioner-focused roundtable, convened by The International Society for the Study of Rural Crime (www.issrc.n…

Inducing Neural Collapse to a Fixed Hierarchy-Aware Frame for Reducing Mistake Severity Open
There is a recently discovered and intriguing phenomenon called Neural Collapse: at the terminal phase of training a deep neural network for classification, the within-class penultimate feature means and the associated classifier vectors o…

Enhancing Self-Training Methods Open
Semi-supervised learning approaches train on small sets of labeled data along with large sets of unlabeled data. Self-training is a semi-supervised teacher-student approach that often suffers from the problem of "confirmation bias" that oc…

Temperature dependence of the deuterium concentration in C-Si codeposits Open
Silicon carbide is a low-Z material seen as a possible alternative to graphite for some plasma-facing components in magnetic confinement fusion reactors. In this study, we have looked at the deuterium content of C-Si codeposits created by …

Learning When to Say "I Don't Know" Open
We propose a new Reject Option Classification technique to identify and remove regions of uncertainty in the decision space for a given neural classifier and dataset. Such existing formulations employ a learned rejection (remove)/selection…

Developing solid-surface plasma facing components for pilot plants and reactors with replenishable wall claddings and continuous surface conditioning. Part B: required research in present tokamaks Open
The companion part A paper (Stangeby et al 2022) reports a number of independent estimates indicating that high-duty-cycle DT tokamaks starting with pilot plants will likely experience rates of net erosion and deposition of solid PFC, plas…

Confident AI Open
In this paper, we propose "Confident AI" as a means to designing Artificial Intelligence (AI) and Machine Learning (ML) systems with both algorithm and user confidence in model predictions and reported results. The 4 basic tenets of Confid…

Revisiting Batch Norm Initialization Open
Batch normalization (BN) is comprised of a normalization component followed by an affine transformation and has become essential for training deep neural networks. Standard initialization of each BN in a network sets the affine transformat…

Posterior Adaptation With New Priors Open
Classification approaches based on the direct estimation and analysis of posterior probabilities will degrade if the original class priors begin to change. We prove that a unique (up to scale) solution is possible to recover the data likel…

2017 NIST OAGi workshop: enabling composable service-oriented manufacturing systems Open
This report summarizes the results from the 2017 NIST/OAGi Workshop: Enabling Composable Service-Oriented Manufacturing Systems, which was held at the National Institute of Standards and Technology campus in Gaithersburg, MD, on April 10-1…

Thermo-oxidation of laboratory-produced undoped and W-doped carbon films: A reaction product analysis Open
Thermo-oxidation is a technique where O2 gas is used to remove carbon co-deposits at elevated temperatures from plasma-facing materials of fusion devices. Following thermo-oxidation, the reaction products produced will need to be managed b…
