Government Ownership, Political Regime, and Flipping of IPOs in Pakistan: Evidence from Emerging Market

open access: yesSAGE Open
This study investigates how government ownership (state-owned IPOs) and the political regime affect the flipping of IPO shares, as well as the moderating impact of investor demand on the association between the political regime and flipping activity ...

Progressive Bit-Flipping Decoding of Polar Codes: A Critical-Set Based Tree Search Approach

open access: yesIEEE Access, 2018
In successive cancellation (SC) polar decoding, an incorrect estimate of any prior unfrozen bit may bring about severe error propagation in the following decoding, and thus it is desirable to find out and correct an error as early as possible.

Belief Propagation Decoder With Multiple Bit-Flipping Sets and Stopping Criteria for Polar Codes

open access: yesIEEE Access, 2020
Compared with successive cancellation list (SCL) decoders, belief propagation (BP)-based decoders suffer performance loss in middle-and high-signal-to-noise ratio (SNR) regions.

Analysis of deep learning under adversarial attacks in hierarchical federated learning

open access: yesHigh-Confidence Computing
Hierarchical Federated Learning (HFL) extends traditional Federated Learning (FL) by introducing multi-level aggregation in which model updates pass through clients, edge servers, and a global server.

Digital Image Steganography Using Bit Flipping

open access: yesCybernetics and Information Technologies, 2018
This article proposes bit flipping method to conceal secret data in the original image. Here a block consists of 2 pixels and thereby flipping one or two LSBs of the pixels to hide secret information in it. It exists in two variants.

Visualizing conformation transitions of the Lipid II flippase MurJ

open access: yesNature Communications, 2019
MurJ is the flippase for the lipid-linked peptidoglycan precursor Lipid II, a key player in bacterial cell wall synthesis, but the flipping mechanism remains poorly understood.

A New Pixels Flipping Method for Huge Watermarking Capacity of the Invoice Font Image

open access: yesThe Scientific World Journal, 2014
Invoice printing just has two-color printing, so invoice font image can be seen as binary image. To embed watermarks into invoice image, the pixels need to be flipped. The more huge the watermark is, the more the pixels need to be flipped.

Flip signatures

open access: yesErgodic Theory and Dynamical Systems, 2022
AbstractA $D_{\infty }$ -topological Markov chain is a topological Markov chain provided with an action of the infinite dihedral group $D_{\infty }$ . It is defined by two zero-one square matrices A and J satisfying $AJ=JA^{\textsf {T}}$ and $J^2=I$ .
