Modulation of genetic associations with serum urate levels by body-mass-index in humans [PDF]

open access: yes, 2015
We tested for interactions between body mass index (BMI) and common genetic variants affecting serum urate levels, genome-wide, in up to 42569 participants.

A Novel Index Modulation Dimension Based on Filter Domain: Filter Shapes Index Modulation [PDF]

open access: yesIEEE Transactions on Communications, 2021
A novel domain for Index Modulation (IM) named “Filter Domain” is proposed. This new domain generalizes many existing modulations and IM domains. In addition, a novel scheme “Filter Shape Index Modulation” (FSIM) is proposed. This FSIM scheme allows a higher Spectral Efficiency (SE) gain than the time and frequency IM dimensions in Single-Input Single ...

Discrete Multitone Modulation for Maximizing Transmission Rate in Step-Index Plastic Optical Fibres [PDF]

open access: yes, 2009
The use of standard 1-mm core-diameter step-index plastic optical fiber (SI-POF) has so far been mainly limited to distances of up to 100 m and bit-rates in the order of 100 Mbit/s.

Precoder Index Modulation

open access: yesCoRR, 2014
Index modulation, where information bits are conveyed through antenna indices (spatial modulation) and subcarrier indices (subcarrier index modulation) in addition to information bits conveyed through conventional modulation symbols, is getting increased research attention.

Quantum Speedup for Index Modulation [PDF]

open access: yesIEEE Access, 2021
This paper presents a quantum-assisted index modulation for next-generation IoT wireless networks. The NP-hard index selection problem is first formulated by a quadratic unconstrained binary optimization (QUBO) problem consisting of constraints of feasible solutions.

Strong modulation instability in a silicon–organic hybrid slot waveguide [PDF]

open access: yes, 2015
In this paper, we investigate the strong modulation instability (MI) at telecommunication band in a silicon-organic hybrid slot waveguide. The organic material of polymer poly (bis para-toluene sulfonate) of 2, 4-hexadiyne 1, 6 diol (PTS), which has high

OFDM With Hybrid Number and Index Modulation [PDF]

open access: yesIEEE Access, 2020
A novel transmission scheme is introduced for efficient data transmission by conveying additional information bits through jointly changing the index and number of active subcarriers within each orthogonal frequency division multiplexing (OFDM) subblock. The proposed scheme is different from the conventional OFDM-subcarrier number modulation (OFDM-SNM)

Deep Learning-Assisted Index Estimator for Generalized LED Index Modulation OFDM in Visible Light Communication

open access: yesPhotonics, 2021
In this letter, we present the first attempt of active light-emitting diode (LED) indexes estimating for the generalized LED index modulation optical orthogonal frequency-division multiplexing (GLIM-OFDM) in visible light communication (VLC) system by ...

Knot modules and the Nakanishi index [PDF]

open access: yesProceedings of the American Mathematical Society, 2002
This paper is concerned with a knot invariant called the Nakanishi index. It is defined as the size of the smallest square matrix which presents the knot module as a \(\mathbb{Z}[t, t^{-1}]\)-module. This invariant seems to have first been defined by Kawauchi who proved that it coincides with the size of a minimal generating set for the knot module ...
