Relationships between Northwest Flow Snowfall and Topography in the Southern Appalachians
"... This paper analyzes the relationships between northwest flow snowfall (NWFS) and various topographic and geographic (TOPO/GEOG) variables in the Southern Appalachian Mountains of the southeastern U.S. We identify NWFS events on the basis of low-level wind direction, extract values for the TOPO/GEOG ..."

A Topos Theory Foundation for Quantum Mechanics
"... The theory of quantum mechanics is examined using non-standard real numbers, called quantum real numbers (qr-numbers), that are constructed from standard Hilbert space entities. Our goal is to resolve some of the paradoxical features of the standard theory by providing the physical attributes of qua ..."

of quantum systems with numerical values that are Dedekind real numbers in the topos of sheaves on the state space of the quantum system. The measured standard real number values of a physical attribute are then obtained as constant qr-number approximations to variable qr-numbers. Considered as attributes
Abstract Analysis of the Queue-Length Distribution for the Discrete-Time Batch-Service Geo/G a,Y /1/K Queue
"... In this paper, we consider a discrete-time finite-capacity queue with Bernoulli arrivals and batch services. In this queue, the single server has a variable service capacity and serves the customers only when the number of customers in system is at least a certain threshold value. For this queue, we ..."

Nonlinear Models of Neural and Genetic Network Dynamics: Natural Transformations of Łukasiewicz Logic LM-Algebras in a Łukasiewicz-Topos as Representations of Neural Network Development and
"... A categorical and Łukasiewicz-Topos framework for Łukasiewicz LM-Algebraic Logic models of nonlinear dynamics in complex functional systems such as neural networks, genomes and cell interactomes is proposed. Łukasiewicz Algebraic Logic models of genetic networks and signaling pathways in cells are f ..."

Mitotic chromatin condensation in vitro using somatic cell extracts and nuclei with variable levels of endogenous topoisomerase H
- J. Cell
, 1990
"... Abstract. We report the development of a new method for producing mitotic extracts from tissue culture cells. These extracts reproducibly promote the condensation of chromatin in vitro when incubated with purified interphase nuclei. This condensation reaction is not species specific, since nuclei fr ..."

from chicken, human, and hamster cell lines all undergo chromatin condensation upon incubation with the extract. We have used this extract to investigate the role of DNA topoisomerase II (topo II) in the chromosome condensation process. Chromatin condensation does not require the presence of soluble
What"-Then-"Where" in visual working memory: an event-related fMRI study
- Journal of Cognitive Neuroscience
, 1999
"... Behavioral studies indicate that spatial and object working memory are computed by dissociable subsystems. We investi-gated the neural bases of this dissociation with a whole-brain fMRI design and analysis technique that permitted direct as-sessment of delay-period activity, uncontaminated by other ..."

Object-speciªc delay-period activity was found predominantly in ventral re-gions of the posterior cortex and demonstrated more topo-graphic variability across
VARIABLE SETS OVER AN ALGEBRA OF LIFETIMES: A CONTRIBUTION OF LATTICE THEORY TO THE STUDY OF COMPUTATIONAL TOPOLOGY
"... Abstract. A topos theoretic generalisation of the category of sets allows for modelling spaces which vary according to time intervals. Persistent homology, or more generally, persistence is a central tool in topological data analysis, which examines the structure of data through topology. The basic ..."

"... Abstract. Topoisomerase II alpha (topo II·) is an enzyme that in normal cells is expressed predominantly in the S/G2/M-phase of the cell cycle. In malignant cells, in vitro studies have indicated that the expression of topo II alpha is both higher and less dependent on the proliferation state in the ..."
