Iterative intersymbol interference cancellation in vestigial sideband Nyquist–subcarrier modulation system
(Society of Photo-optical Instrumentation Engineers, 2014)The intersymbol interference caused by dispersion, chirp, and a vestigial sideband filter in intensity modulation and a direct detection single carrier system is analyzed theoretically and numerically. An iterative nonlinear ... -
40-Gbps vestigial sideband half-cycle Nyquist subcarrier modulation transmission experiment and its comparison with orthogonal frequency division multiplexing
(Society of Photo-optical Instrumentation Engineers, 2014-09-24)We experimentally demonstrate the superior performance of a 40-Gbps 16-QAM half-cycle Nyquist subcarrier modulation (SCM) transmission over a 100-km uncompensated standard single-mode fiber using dual-drive Mach-Zehnder ... -
Excitation cross section of erbium-doped GaN waveguides under 980 nm optical pumping
(American Institute of Physics, 2014-08-04)Excitation cross section of erbium-doped GaN waveguides is measured to be approximately 2.2×10−21cm2 at 980 nm pumping wavelength. This cross section value is found relatively insensitive to the crystalline quality of ... -
The trough-system algorithm and its application to spatial modeling of Greenland subglacial topography
(International Glaciological Society, 2014-07)Dynamic ice-sheet models are used to assess the contribution of mass loss from the Greenland ice sheet to sea-level rise. Mass transfer from ice sheet to ocean is in a large part through outlet glaciers. Bed topography ... -
Wintertime storage of water in buried supraglacial lakes across the Greenland Ice Sheet
(European Geosciences Union, 2014)Surface melt over the Greenland Ice Sheet (GrIS) is increasing and estimated to account for half or more of the total mass loss. Little, however, is known about the hydrologic pathways that route surface melt within the ... -
Airborne fine-resolution UHF radar: an approach to the study of englacial reflections, firn compaction and ice attenuation rates
(International Glaciological Society, 2015-02)We have built and operated an ultra-wideband UHF pulsed-chirp radar for measuring firn stratigraphy from airborne platforms over the ice sheets of Greenland and West Antarctica. Our analysis found a wide range of capabilities, ... -
Link adaptation for energy-efficient uplink coordinated multi-point receptions
(SpringerOpen, 2011-11-23)We investigate link adaptation methods for energy-efficient uplink coordinated multi-point receptions. A system model for practical cellular networks is introduced, in which only a subset of base stations participates in ... -
Multicell Cooperation and MIMO Technologies for Broadcasting and Broadband Communications

Phase-Shift Cyclic-Delay Diversity for MIMO OFDM Systems
(Hindawi Publishing Corporation, 2010)Phase-shift cyclic-delay diversity (PS CDD) scheme and space-frequency-block-code (SFBC) PS CDD are developed for multiple-input-multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) systems. The proposed ... -
Intercell Interference Coordination through Limited Feedback
(Hindawi Publishing Corporation, 2010)We consider the applications of multicell transmission schemes to the downlink of future wireless communication networks. A multicell multiple-input multiple output-(MIMOs) based scheme with limited coordination among ... -
Measurements and Analysis of Secondary User Device Effects on Digital Television Receivers
(Hindawi Publishing Corporation, 2009-11-30)This article presents results from a study of the potential effects of secondary users operating in unoccupied television spectrum. Television spectrum is known within the wireless communications community as being ... -
Glaciers and Ice Sheets Mapping Orbiter concept
(American Geophysical Union, 2006-05-13)We describe a concept for a spaceborne radar system designed to measure the surface and basal topography of terrestrial ice sheets and to determine the physical properties of the glacier bed. Our primary objective is to ... -

Multilevel resilience analysis of transportation and communication networks
(Springer, 2015-03-27)For many years the research community has attempted to model the Internet in order to better understand its behaviour and improve its performance. Since much of the structural complexity of the Internet is due to its ... -
Mining Adverse Drug Reactions from online healthcare forums using Hidden Markov Model
(Bio Med Central, 2014-10-23)Background Adverse Drug Reactions are one of the leading causes of injury or death among patients undergoing medical treatments. Not all Adverse Drug Reactions are identified before a drug is made available in the market. ... -
Molecular cancer classification using an meta-sample-based regularized robust coding method
(BioMedCentral, 2014-12-03)Motivation Previous studies have demonstrated that machine learning based molecular cancer classification using gene expression profiling (GEP) data is promising for the clinic diagnosis and treatment of cancer. Novel ... -
Towards Inferring Protein Interactions: Challenges and Solutions
(Springer, 2006-04-05)Discovering interacting proteins has been an essential part of functional genomics. However, existing experimental techniques only uncover a small portion of any interactome. Furthermore, these data often have a very high ... -
Domain-Based Predictive Models for Protein-Protein Interaction Prediction
(Springer, 2006-04-20)Protein interactions are of biological interest because they orchestrate a number of cellular processes such as metabolic pathways and immunological recognition. Recently, methods for predicting protein interactions using ... -
