Soft Decoding Assisted Interference Cancellation in a Non-Binary LDPC Coded Fast Frequency Hopping Multiuser System Using Product Combining [PDF]

open access: yes, 2007
In this contribution, soft-input-soft-output (SISO) decoding aided successive interference cancellation (SIC) is considered in fast frequency hopping (FFH), M-ary frequency shift keying (MFSK) using product combining (PC), when operating in multiple ...

A Radiation-Hardened Low-Power SRAM with Enhanced Write Capability for Space Applications

open access: yesApplied Sciences
With continued scaling of CMOS technology, the critical charge required for state retention in SRAM cells has decreased, leading to increased vulnerability to radiation-induced soft errors such as single-event upsets (SEUs) and single-event multi-node ...

DESPINA: Synthesis of High-Fidelity Planetary Horizon Reconstructions Using DEM-Guided Diffusion [PDF]

open access: yesISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences
Ground-level horizon imagery is scarce across planetary bodies, making representation-centred approaches attractive for down-stream geospatial tasks.

Marginality from leading soft gluons

open access: yesJournal of High Energy Physics
Marginal operators in a d-dimensional conformal field theory (CFT), those with conformal dimension ∆ = d, give us information about the space of related theories.

A nonuniform popularity-similarity optimization (nPSO) model to efficiently generate realistic complex networks with communities

open access: yesNew Journal of Physics, 2018
The investigation of the hidden metric space behind complex network topologies is a fervid topic in current network science and the hyperbolic space is one of the most studied, because it seems associated to the structural organization of many real ...

On a generalized soft metric space

open access: yes, 2019
Summary: In this paper our aim is to obtain new generalized fixed-point results. To do this, we introduce a new generalized soft metric space called a soft \(S\)-metric space. We investigate some basic facts, relations and topological properties of this space.

A cohomological characterisation of Yu's Property A for metric spaces

open access: yes, 2012
We introduce the notion of an asymptotically invariant mean as a coarse averaging operator for a metric space and show that the existence of such an operator is equivalent to Yu’s property A.

The Samuel realcompactification of a metric space [PDF]

open access: yes, 2017
In this paper we introduce a realcompactification for any metric space (X, d), defined by means of the family of all its real-valued uniformly continuous functions.

Autonomous Maneuvering Decision-Making Method for Unmanned Aerial Vehicle Based on Soft Actor-Critic Algorithm

open access: yesDrones
Focusing on continuous action space methods for autonomous maneuvering decision making in 1v1 unmanned aerial vehicle scenarios, this paper first establishes a UAV kinematic model and a decision-making framework under the Markov Decision Process. Second,

Quantification of Tumor Burden in a Genetically Engineered Mouse Model of Lung Cancer by Micro-CT and Automated Analysis

open access: yesTranslational Oncology, 2015
Genetically engineered mouse models (GEMMs) of lung cancer closely recapitulate the human disease but suffer from the difficulty of evaluating tumor growth by conventional methods.
