The Module Index and Invertible Ideals [PDF]
Transactions of the American Mathematical Society, 1970 A. Frohlich used the module index to classify the projective modules of an order in a finite dimensional commutative separable algebra over the quotient field of a Dedekind domain. This paper extends Frohlich's results and classifies the invertible ideals of an order in a noncommutatives eparable algebra.

Variability of the Pulsed Radio Emission from the Large Magellanic Cloud Pulsar PSR J0529-6652 [PDF]
, 2012 We have studied the variability of PSR J0529-6652, a radio pulsar in the LMC, using observations conducted at 1390 MHz with the Parkes 64-m telescope.

Multi-Hop Index Modulation-Aided OFDM With Decode-and-Forward Relaying
IEEE Access, 2018 In this paper, we propose a multi-hop index modulation-aided orthogonal frequency-division multiplexing (IM-aided OFDM) system, which employs decode-and-forward (DF) relaying techniques to enable the transmission of information from source to destination

Low-Complexity Detection for Index Modulation Multiple Access
IEEE Wireless Communications Letters, 2020 Index modulation multiple access (IM-MA) is recently proposed to exploit the IM concept to the uplink multiple access system, where multiple users transmit their own signals via the selected time slots.

New singular Gelfand-Tsetlin $\mathfrak{gl} (n)$-modules of index 2 [PDF]
, 2016 Singular Gelfand-Tsetlin modules of index 2 are modules whose tableaux bases may have singular pairs but no singular triples of entries on each row. In this paper we construct singular Gelfand-Tsetlin modules for arbitrary singular character of index 2.

IEEE Systems Journal, 2020 In this article, a high data rate and energy-efficient multiple-input multiple-output transmission scheme is considered by combining two popular and rational modulation techniques: spatial modulation (SM) and code index modulation-spread spectrum (CIM-SS)
