Low-Complexity Differential Spatial Modulation Schemes for a Lot of Antennas

open access: yesIEEE Access, 2020
Spatial modulation (SM) uses a single antenna for transmission each time to avoid synchronization and interferences among transmitter antennas, and differential SM (DSM) is a kind of SM technique that does not need pilot symbols and channel estimation ...

Acyclic Solos and Differential Interaction Nets [PDF]

open access: yesLogical Methods in Computer Science, 2010
We present a restriction of the solos calculus which is stable under reduction and expressive enough to contain an encoding of the pi-calculus. As a consequence, it is shown that equalizing names that are already equal is not required by the encoding of ...

PrivBV: Distance-Aware Encoding for Distributed Data with Local Differential Privacy

open access: yesTsinghua Science and Technology, 2022
Recently, local differential privacy (LDP) has been used as the de facto standard for data sharing and analyzing with high-level privacy guarantees.

RESEARCH ON DIFFERENTIAL CODING METHOD FOR SATELLITE REMOTE SENSING DATA COMPRESSION [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2012
Data compression, in the process of Satellite Earth data transmission, is of great concern to improve the efficiency of data transmission. Information amounts inherent to remote sensing images provide a foundation for data compression in terms of ...

Differential encoding in prefrontal cortex projection neuron classes across cognitive tasks

open access: yesbioRxiv, 2020
Single-cell transcriptomics has been widely applied to classify neurons in the mammalian brain, while systems neuroscience has historically analyzed the encoding properties of cortical neurons without considering cell types.

Sixty Years of Coherent Versus Non-Coherent Tradeoffs and the Road From 5G to Wireless Futures

open access: yesIEEE Access, 2019
Sixty years of coherent versus non-coherent tradeoff as well as the twenty years of coherent versus non-coherent tradeoff in Multiple-Input Multiple-Output (MIMO) systems are surveyed. Furthermore, the advantages of adaptivity are discussed.

Comparative Study of Swarm-Based Algorithms for Location-Allocation Optimization of Express Depots

open access: yesDiscrete Dynamics in Nature and Society, 2022
The location and capacity of express distribution centers and delivery point allocation are mixed-integer programming problems modeled as capacitated location and allocation problems (CLAPs), which may be constrained by the position and capacity of ...

Differential methylation of microRNA encoding genes may contribute to high myopia

open access: yesFrontiers in Genetics, 2023
Introduction: High myopia (HM), an eye disorder with a refractive error ≤−6.0 diopters, has multifactorial etiology with environmental and genetic factors involved. Recent studies confirm the impact of alterations in DNA methylation and microRNAs (miRNAs)
