Modular Metamaterials for Adaptable MRI Signal Control: Combining Dipole Array With a New Hexagon‐Based Artificial Dielectrics

open access: yesAdvanced Science, EarlyView.
A flexible, hexagonally packed artificial dielectric providing a wide range of effective permittivities (εr ≈ 30–1400) without lumped elements was developed for clinical and ultra‐high‐field MRI. Combined with modular passive‐dipole arrays, the system enables adaptable RF field shaping through electric‐ and magnetic‐dipole tuning.

Interleaver Design for Parallel Concatenated Block Codes With Arbitrary Lengths

open access: yesIEEE Access
Parallel Concatenated Block (PCB) codes are conventionally constituted by two identical linear systematic block codes, as component codes, linked by an interleaver. In general, the PCB code’s interleaver length (or message length) is the square of

Interleaved Prange: A New Generic Decoder for Interleaved Codes

open access: yes, 2022
Due to the recent challenges in post-quantum cryptography, several new approaches for code-based cryptography have been proposed. For example, a variant of the McEliece cryptosystem based on interleaved codes was proposed. In order to deem such new settings secure, we first need to understand and analyze the complexity of the underlying problem, in ...

Single‐Molecule Imaging of Endogenous RNA Using a Miniaturized and Circularly Permuted CRISPR‐Cas13 Degron‐Masking System CDegSR

open access: yesAdvanced Science, EarlyView.
CDegSR, a new tool for imaging RNA at single molecule level in living cells was developed by researchers. Background noise was eliminated by protein engineering and making it degrade when not bound to its target. This allowed individual RNA molecules to be clearly imaged and tracked.

Fixed‐latency architecture for multi‐stage algebraic interleavers in interleave division multiple access systems

open access: yesElectronics Letters, 2022
In this letter, a fixed‐latency interleaver architecture is proposed for interleave division multiple access (IDMA) systems. The existing multi‐stage algebraic interleaver suffers from the high latency originated from a series of multipliers and adders ...

Probabilistic Computing via Gate‐Tunable Random Telegraph Noise

open access: yesAdvanced Science, EarlyView.
Intrinsic random telegraph noise in metal–oxide–semiconductor field‐effect transistors is harnessed to create gate‐tunable probabilistic bits. By modulating carrier‐trapping dynamics, the device produces stochastic binary outputs with a continuous bias‐to‐probability transfer.
