A Fundamental Unit of O_K
… case we make use of Pells equation to compute units in the ring O<sub>F. </sub> Consider the parallel to the classical case and the quadratic field extension that creates the ring O<sub>K</sub>. We use the generalized Pell's equation to find the units in this ring since they are solutions. …

Situated Objectivity: Ethical Judgment, Critique and Justification After Wittgenstein
… is resolved by taking action itself as the fundamental unit of study.

Quintic Abelian Fields
… basis are computed. A method for finding the fundamental units, regulators and class numbers is then developed. Tables listing the coefficients of a generating polynomial, the regulator, the class number, and a coefficients of a fundamental unit are given for 1527 quintic abelian fields. Of …

A Theory for the Measurement of Internet Information Retrieval
… objective relevance judgments, and by adopting a fundamental unit of measure developed for the cyberspace of Internet information retrieval rather than using recall and precision-type measures. The proposed measure, the Content-bearing Click (CBC) Ratio, was developed as a quantitative measure …

The Asymptotic Development of The Equations of Nuclear Reactor Theory
… which are close to critical. The product of the fundamental unit-cell transport theory eigenfunction and the fundamental cell-homogenized diffusion theory eigenfunction is shown to correspond to the leading asymptotic solution to the transport equation for large near-critical heterogeneous …

Improving regulator verification and compact representations in real quadratic fields
… and to a closely related quantity called the fundamental unit. Though it is somewhat simple to show these equations have non-trivial solutions, finding unconditionally correct solutions and being able to express them is extremely challenging, both from a theoretical and a computational …

Numerical Tests of Two Conjectures in Fake Real Quadratic Orders
… D∤b where b is the second coefficient of the fundamental unit in the real quadratic field Q(√D). No counterexamples have been found in real quadratic fields but we found numerous counterexamples in fake real quadratic orders and this is evidence that the conjecture is false for real quadratic …

Behavioral dynamics of public transit ridership in Chicago and impacts of COVID-19
Public transportation ridership analysis in the United States has traditionally centered around the tracking and reporting of the count of trips taken on the system. Such analysis is valuable but incomplete. This work presents a ridership analysis framework that keeps the rider, rather than the …

Chromatin Structure of Schizosaccharomyces Pombe: From the Lowest to the Highest Orders of Folding
… Thus, the chromatosome cannot be the fundamental unit of chromatin structure in all eukaryotes. The cross-linker model of chromatin higher-order structure is incompatible with a nucleosome repeat length of 156 bp, and thus cannot apply to all eukaryotes. The solenoid model of higher …

Development of Histotripsy Focused Ultrasound Devices Using Rapid Prototyping Methods
… or disc, which emits the ultrasound wave, is the fundamental unit of the transducer. For modular prototype histotripsy designs, these PZTs are housed in a 3D printed focused lens. However, 3D printing transducer components can be time consuming and expensive when scaling up manufacturing, and 3D …

Regulation and function of histone variant H2BE in neurons
The nucleosome is the fundamental unit of the genome that organizes DNA and is made of four histone proteins: H2A, H2B, H3, and H4. Regulation of histone proteins affects gene expression through multiple mechanisms, including exchange with histone variants. While variants of H2A and H3 have well …

Bioinformatics and database tools for glycans
… of their tremendous information density per fundamental unit, their often-branched structures, and the complicated nature of their building blocks. The GlycoBank, an online database of known GAG structures and functions, has been developed to overcome many of these difficulties by developing …

Investigating protein folding by the de novo design of an α-helix oligomer
… model defines the knob-socket construct as the fundamental unit of packing within protein structure. The knob-socket model characterizes packing specificity in terms of amino acid preferences for sockets in different environments: sockets filled with a knob are involved in inter-helical …

The essential message : Claude Shannon and the making of information theory
… a precise way to quantify it-in his theory, the fundamental unit of information is the bit. He also showed how data could be "compressed" before transmission and how virtually error-free communication could be achieved. The concepts Shannon developed in his paper are at the heart of today's …

The Interdependence of Scientists in the Era of Team Science: An Exploratory Study Using Temporal Network Analysis
… and the emergence of the research group as the fundamental unit of organization of science affecting scientists’ opportunities to collaborate? Are the majority of scientists becoming dependent on a select subset of their peers to organize the intergroup collaborations that are becoming the norm …

Single-molecule study of the DNA helicase regulating genomic stability
… analysis and identified that the fundamental unit of translocation kinetics is a ‘one nucleotide uniform step’. Our result reconciles debates between the structural and biochemical studies on the motor mechanism, and moreover, clarifies a popular oversight regarding molecular …

Modeling the mechanical behavior of amorphous metals by shear transformation zone dynamics
… the shear transformation zone (STZ) as the fundamental unit of deformation, and coarse-grains an amorphous collection of atoms into an ensemble of STZs on a mesh. By employing finite element analysis and a kinetic Monte Carlo algorithm, the modeling technique is capable of simulating …

Organisational phylogenesis : Developing and evaluating a memetic methodology.
… code. This new replicator represents the fundamental unit of cultural transmission and was termed by evolutionist, Richard Dawkins, as the meme. The memetic position re-introduces many often neglected, sometimes shunned, evolutionary arguments into social and organisational debate by …

Patterned substrates for cell culture with electrohydrodynamic jet printing
… used to study the formation of “nodules,” the fundamental unit of bone formation in vitro. Nodule structure was evaluated after four days in culture, and patterned substrates were shown to be compatible with traction force microscopy (TFM). These represented preliminary results for a larger …

Tackling the current limitations of bacterial taxonomy with genome-based classification and identification on a crowdsourcing Web service
… in animal and plant taxonomy, the species is the fundamental unit of taxonomy, but the genetic and phenotypic diversity that exists within a single bacterial species is substantially higher compared to animal or plant species. Therefore, the current "type"-centered classification scheme that …
