Information-theoretic limits of dense underwater networks
(Institute of Electrical and Electronics Engineers (IEEE), 2011-11)Information-theoretic throughput scaling laws are analyzed in an underwater acoustic network with n regularly located nodes on a unit square, in which both bandwidth and received signal power can be severely limited. A ... -
Information-Theoretic Lower Bounds on the Storage Cost of Shared Memory Emulation
(Association for Computing Machinery (ACM), 2016-07)© 2016 ACM. The focus of this paper is to understand storage costs of em- ulating an atomic shared memory over an asynchronous, dis- tributed message passing system. Previous literature has de- veloped several shared memory ... -
Information-theoretical Limits of Recursive Estimation and Closed-loop Control in High-contrast Imaging
(American Astronomical Society, 2021) -
Informational and Causal Architecture of Continuous-time Renewal Processes
(Springer US, 2017-04)We introduce the minimal maximally predictive models (ϵ-machines) of processes generated by certain hidden semi-Markov models. Their causal states are either discrete, mixed, or continuous random variables and causal-state ... -
Informational Braess’ Paradox: The Effect of Information on Traffic Congestion
(Institute for Operations Research and the Management Sciences (INFORMS), 2018-08)To systematically study the implications of additional information about routes provided to certain users (e.g., via GPS-based route guidance systems), we introduce a new class of congestion games in which users have ... -
Informational Challenges in Omnichannel Marketing: Remedies and Future Research
(SAGE Publications, 2020-11)Omnichannel marketing is often viewed as the panacea for one-to-one marketing, but this strategic path is mired with obstacles. This article investigates three challenges in realizing the full potential of omnichannel ... -
Informational Complementarity
(Institute for Operations Research and the Management Sciences (INFORMS), 2019-12)Many products have similar or common attributes and are thus correlated. We show that, when these attributes are uncertain for consumers, a complementarity effect can arise among competing products in the sense that the ... -
Informational lesions: optical perturbation of spike timing and neural synchrony via microbial opsin gene fusions
(Frontiers Research Foundation, 2009-07)Synchronous neural activity occurs throughout the brain in association with normal and pathological brain functions. Despite theoretical work exploring how such neural coordination might facilitate neural computation and ... -
Informational Rigidities and the Stickiness of Temporary Sales
(Elsevier BV, 2017-10)How do retailers react to cost changes? While temporary sales account for 95% of price change in our data, retail prices respond to a wholesale cost increase entirely through the regular price. Sales actually respond ... -
Informative path planning for anomaly detection in environment exploration and monitoring
(Elsevier BV, 2022-01)An unmanned autonomous vehicle (UAV) is sent on a mission to explore and reconstruct an unknown environment from a series of measurements collected by Bayesian optimization. The success of the mission is judged by the UAV’s ... -
Informative sensing of natural images
(Institute of Electrical and Electronics Engineers, 2010-02)The theory of compressed sensing tells a dramatic story that sparse signals can be reconstructed near-perfectly from a small number of random measurements. However, recent work has found the story to be more complicated. ... -
Informed selection of future climates
(Springer Netherlands, 2014-07)Analysis of climate change is often computationally burdensome. Here, we present an approach for intelligently selecting a sample of climates from a population of 6800 climates designed to represent the full distribution ... -
Informing Performance Metrics of Advanced I&C Systems for Liquid Fueled Fast Molten Salt Reactors

Informing sleep policy through field experiments

Informing transparency in the Paris Agreement: the role of economic models
(Taylor & Francis, 2017-08)Establishing a credible and effective transparency regime to support the Paris Agreement – broader than its formal ‘transparency framework’ – will be both crucial and challenging. The Agreement provides for review of ... -
Infrared absorption of n-type tensile-strained Ge-on-Si
(Optical Society of America, 2013-02)We analyze the IR absorption of tensile-strained, n-type Ge for Si-compatible laser applications. A strong intervalley scattering from the indirect L valleys to the direct Γ valley in n[superscript +] Ge-on-Si is reported ... -
Infrared birefringence imaging of residual stress and bulk defects in multicrystalline silicon
(American Institute of Physics (AIP), 2010-09)This manuscript concerns the application of infrared birefringence imaging (IBI) to quantify macroscopic and microscopic internal stresses in multicrystalline silicon (mc-Si) solar cell materials. We review progress to ... -
AN INFRARED NEBULA ASSOCIATED WITH δ CEPHEI: EVIDENCE OF MASS LOSS?
(IOP Publishing, 2010-12)We present the discovery of an infrared nebula around the Cepheid prototype δ Cephei and its hot companion HD 213307. Large-scale (~2.1 × 10[superscript 4] AU) nebulosity is detected at 5.8, 8.0, 24, and 70 μm. Surrounding ... -
Infrared reflectance and transmission spectra in II-VI alloys and superlattices
(American Physical Society (APS), 2011-11)Room temperature measurements of the far-infrared (FIR) reflectance spectra are reported for the polar optical phonons in a series of bulk Cd[subscript x]Zn[subscript 1−x]Te (0 ≤ x ≤ 1) and CdSe[subscript x]Te[subscript ... -
An Infrared Search for Kilonovae with the WINTER Telescope. I. Binary Neutron Star Mergers
(American Astronomical Society, 2022-02-01)The Wide-Field Infrared Transient Explorer (WINTER) is a new 1 deg2 seeing-limited time-domain survey instrument designed for dedicated near-infrared follow-up of kilonovae from binary neutron star (BNS) and neutron ...
