Finality and Foreclosure: Determining a Homeowner’s Ability to Appeal in Mortgage Foreclosure Cases
AI in Adjudication and Administration
The use of artificial intelligence has expanded rapidly in recent years across many aspects of the economy. For federal, state, and local governments in the United States, interest in artificial intelligence has manifested in the use of a series of digital tools, including the occasional deployment of machine learning, to aid in the performance of a variety of governmental functions. In this paper, we canvas the current uses of such digital tools and machine-learning technologies by the judiciary and administrative agencies in the United States. Although we have yet to see fully automated decision-making find its way into either adjudication or administration, governmental entities at all levels are taking steps that could lead to the implementation of automated, machine-learning decision tools in the relatively near future. Within the federal and state court systems, for example, machine-learning tools have yet to be deployed, but other efforts have put in place digital building blocks toward such use. These efforts include the increased digitization of court records that algorithms will need to draw upon for data, the growth of online dispute resolution inside and outside of the courts, and the incorporation of non-learning risk assessment tools as inputs into bail, sentencing, and parole decisions. Administrative agencies have proven much more willing than courts to use machine-learning algorithms, deploying such algorithmic tools to help in the delivery of public services, management of government programs, and targeting of enforcement resources. We discuss already emerging concerns about the deployment of artificial intelligence and related digital tools to support judicial and administrative decision-making. If artificial intelligence is managed responsibly to address such concerns, the use of algorithmic tools by governmental entities throughout the United States would appear to show much future promise. This status report on current uses of algorithmic tools can serve as a benchmark against which to gauge future growth in the use of artificial intelligence in the public sector
The Interplay of Structure and Dynamics in the Raman Spectrum of Liquid Water over the Full Frequency and Temperature Range
While many vibrational Raman spectroscopy studies of liquid water have
investigated the temperature dependence of the high-frequency O-H stretching
region, few have analyzed the changes in the Raman spectrum as a function of
temperature over the entire spectral range. Here, we obtain the Raman spectra
of water from its melting to boiling point, both experimentally and from
simulations using an ab initio-trained machine learning potential. We use these
to assign the Raman bands and show that the entire spectrum can be well
described as a combination of two temperature-independent spectra. We then
assess which spectral regions exhibit strong dependence on the local
tetrahedral order in the liquid. Further, this work demonstrates that changes
in this structural parameter can be used to elucidate the temperature
dependence of the Raman spectrum of liquid water and provides a guide to the
Raman features that signal water ordering in more complex aqueous systems

Analysis of Expression Patterns: The Scope of the Problem, the Problem of Scope
Studies of the expression patterns of many genes simultaneously lead to the observation that even in closely related pathologies, there are numerous genes that are differentially expressed in consistent patterns correlated to each sample type. The early uses of the enabling technology, microarrays, was focused on gathering mechanistic biological insights. The early findings now pose another clear challenge, finding ways to effectively use this kind of information to develop diagnostics
Hydrophobic but water-friendly: favorable water–perfluoromethyl interactions promote hydration shell defects
Although perfluorination is known to enhance hydrophobicity and change protein activity, its influence on hydration-shell structure and thermodynamics remains an open question. Here we address that question by combining experimental Raman multivariate curve resolution spectroscopy with theoretical classical simulations and quantum mechanical calculations. Perfluorination of the terminal methyl group of ethanol is found to enhance the disruption of its hydration-shell hydrogen bond network. Our results reveal that this disruption is not due to the associated volume change but rather to the electrostatic stabilization of the water dangling OH···F interaction. Thus, the hydration shell structure of fluorinated methyl groups results from a delicate balance of solute–water interactions that is intrinsically different from that associated with a methyl group
