Side Lobe Suppression in NC-OFDM Systems Using Variable Cancellation Basis Function

open access: yesIEEE Access, 2017
In non-continuous orthogonal frequency division multiplexing (NC-OFDM)-based cognitive radio system, the sidelobe suppression methods use the fixed length rectangular windowing functions for canceling carriers (CCs) like the extended active interference ...

Computational Studies of Light Shift in Raman-Ramsey Interference-Based Atomic Clock

open access: yes, 2014
Determining light shift in Raman-Ramsey interference is important for the development of atomic frequency standards based on a vapor cell. We have accurately calculated light shift in Raman-Ramsey interference using the density-matrix equations for a ...

ORIGINAL ARTICLE: Suppression of Mamu‐AG by RNA Interference [PDF]

open access: yesAmerican Journal of Reproductive Immunology, 2009
Problem  The role of placental major histocompatibility complex (MHC) class I molecules in pregnancy is not well understood. Mamu‐AG, the rhesus monkey homology of human leukocyte antigen (HLA)‐G expressed in the human placenta, was targeted for degradation by RNA interference (RNAi), a powerful tool to aid in determining gene function, to determine ...

Surfaceome: a new era in the discovery of immune evasion mechanisms of circulating tumor cells

open access: yesMolecular Oncology, EarlyView.
In the era of immunotherapies, many patients either do not respond or eventually develop resistance. We propose to pave the way for proteomic analysis of surface‐expressed proteins called surfaceome, of circulating tumor cells. This approach seeks to identify immune evasion mechanisms and discover potential therapeutic targets. Circulating tumor cells (

The decoherence and interference of cosmological arrows of time for a de Sitter universe with quantum fluctuations

open access: yes, 2018
We consider the superposition of two semiclassical solutions of the Wheeler-DeWitt equation for a de Sitter universe, describing a quantized scalar vacuum propagating in a universe that is contracting in one case and expanding in the other, each ...

Interference suppression in congested undersea environments

open access: yesOCEANS 2015 - Genova, 2015
Many acoustic channels suffer from interference which is neither narrowband nor impulsive. This relatively long duration partial band interference can be particularly detrimental to system performance. In operational networks, many “dropped” messages are lost due to partial band interference which corrupts different portions of the received signal ...

Circulating tumor cells: advancing personalized therapy in small cell lung cancer patients

open access: yesMolecular Oncology, EarlyView.
Small cell lung cancer (SCLC) is an aggressive form of lung cancer that spreads rapidly to secondary sites such as the brain and liver. Cancer cells circulating in the blood, “circulating tumor cells” (CTCs), have demonstrated prognostic value in SCLC, and evaluating biomarkers on CTCs could guide treatment decisions such as for PARP inhibitors ...

Cascaded Multitype Interferences Suppression Method Using Sparse Representation and Array Processing for GNSS Receiver

open access: yesInternational Journal of Antennas and Propagation, 2017
Interference suppression techniques have been intensively studied in nearly two decades due to their importance for maintaining the integrity and functionality of global navigation satellite system (GNSS).

Successive Decode-and-Forward Relaying With Privacy-Aware Interference Suppression

open access: yesIEEE Access, 2020
Successive relaying holds the promise of achieving spatial diversity gain for single-antenna users while recovering the multiplexing loss due to the half-duplex relaying in B5G/6G.
