Ramped-amplitude NOVEL
(AIP Publishing, 2017-04)We present a pulsed dynamic nuclear polarization (DNP) study using a ramped-amplitude nuclear orientation via electron spin locking (RA-NOVEL) sequence that utilizes a fast arbitrary waveform generator (AWG) to modulate ... -
Ramsey numbers of cubes versus cliques
(Springer-Verlag/Bolyai Society, 2014-11)The cube graph Q[subscript n] is the skeleton of the n-dimensional cube. It is an n-regular graph on 2[superscript n] vertices. The Ramsey number r(Q[subscript n] ;K[subscript s]) is the minimum N such that every graph of ... -
Ramsey-type results for semi-algebraic relations
(Association for Computing Machinery (ACM), 2013-06)For natural numbers d and t there exists a positive C such that if F is a family of n[superscript C] semi-algebraic sets in R[superscript d] of description complexity at most t, then there is a subset F' of F of size $n$ ... -
The RAND Health Insurance Experiment, Three Decades Later
(American Economic Association, 2013-02)Between 1974 and 1981, the RAND health insurance experiment provided health insurance to more than 5,800 individuals from about 2,000 households in six different locations across the United States, a sample designed to be ... -
Randolph : Boston's gateway suburb
(Massachusetts Institute of Technology, 2010)In the last two decades, certain American suburbs have begun to struggle with issues traditionally thought of as urban problems and dealt with in city settings, such as failing schools, fragmented community, affordable ... -
Random access DNA memory using Boolean search in an archival file storage system
(Springer Science and Business Media LLC, 2021)DNA is an ultrahigh-density storage medium that could meet exponentially growing worldwide demand for archival data storage if DNA synthesis costs declined sufficiently and if random access of files within exabyte-to-yot ... -
Random Access Heterogeneous Mimo Networks
(Association for Computing Machinery (ACM), 2011-08)This paper presents the design and implementation of 802.11n+, a fully distributed random access protocol for MIMO networks. 802.11n+ allows nodes that differ in the number of antennas to contend not just for time, but ... -
Random access wireless networks with controlled mobility
(Institute of Electrical and Electronics Engineers, 2009-08)This paper considers wireless networks where messages arriving randomly (in time and space) are collected by a mobile receiver. The messages are transmitted to the mobile receiver according to a random access scheme and ... -
Random and Raster: Display Technologies and the Development of Videogames
(Institute of Electrical and Electronics Engineers, 2009-08)Videogame developers have utilized many types of display technology, from oscilloscopes to Teletypes to high-definition LCD displays. Two significant early display technologies, raster scan and random scan CRTs, played a ... -
Random channel kinetics for reaction–diffusion systems
(Elsevier, 2009-08)A random channel approach is developed for reaction–diffusion processes in disordered systems. Although the starting point of our research is the kinetic study of the decay and preservation of marine organic carbon, our ... -
The random coefficients logit model is identified
(Elsevier, 2011-09)The random coefficients multinomial choice logit model, also known as the mixed logit, has been widely used in empirical choice analysis for the last thirty years. We prove that the distribution of random coefficients in ... -
Random collisions on branched networks: How simultaneous diffusion prevents encounters in inhomogeneous structures
(American Physical Society, 2012-08)A huge variety of natural phenomena, including prey-predator interaction, chemical reaction kinetics, foraging, and pharmacokinetics, are mathematically described as encounters between entities performing a random motion ... -
Random contractions and sampling for hypergraph and hedge connectivity
(Association for Computing Machinery, 2017-01)We initiate the study of hedge connectivity of undirected graphs, motivated by dependent edge failures in real-world networks. In this model, edges are partitioned into groups called hedges that fail together. The hedge ... -
Random DNA integrations as an approach to insertional mutagenesis in the zebrafish (Brachydanio rerio)
(Massachusetts Institute of Technology, 1994) -
Random field modeling for interpretation and analysis of layered data
(Massachusetts Institute of Technology, 1987) -
A random finite set based detection and tracking using 3D LIDAR in dynamic environments
(2010-10)In this paper we describe a fully integrated system for detecting and tracking pedestrians in a dynamic urban environment. The system can reliably detect and track pedestrians to a range of 100 m in highly cluttered ... -
Random Finite Set Theory and Centralized Control of Large Collaborative Swarms
(American Institute of Aeronautics and Astronautics (AIAA), 2021)Controlling large swarms of robotic agents presents many challenges, including, but not limited to, computational complexity due to a large number of agents, uncertainty in the functionality of each agent in the swarm, and ... -
Random Lens Imaging
(2006-09-02)We call a random lens one for which the function relating the input light ray to the output sensor location is pseudo-random. Imaging systems with random lensescan expand the space of possible camera designs, allowing new ... -
Random linear network coding for time division duplexing: energy analysis
(Institute of Electrical and Electronics Engineers, 2009-08)We study the energy performance of random linear network coding for time division duplexing channels. We assume a packet erasure channel with nodes that cannot transmit and receive information simultaneously. The sender ... -
Random linear network coding for time division duplexing: When to stop talking and start listening
(Institute of Electrical and Electronics Engineers, 2009-06)A new random linear network coding scheme for reliable communications for time division duplexing channels is proposed. The setup assumes a packet erasure channel and that nodes cannot transmit and receive information ...
