Adaptive Space-Frequency Equalization for SC-FDE Systems With Interference

IEEE Access, 2019
In this paper, we propose a new space-frequency adaptive equalization (SFAE) method for single carrier frequency domain equalization (SC-FDE) systems that can deal with multipath interference from the highly delay-dispersive channel as well as the ...

A Ceramic Network for Hybrid Solid Electrolyte Lithium Metal Batteries

Advanced Science, EarlyView.
An in‐plane aligned Ta‐LLZO ceramic network exhibits superior performance compared to conventional fillers, including single ceramic fibers and particles. The tortuosity within the polymeric phase of hybrid solid electrolytes is identified as a key parameter governing lithium‐ion transport pathways and dendrite suppression.

Performance analysis of WPM‐based transmission with equalization‐aware bit loading

ETRI Journal, 2018
Wavelet packet modulation (WPM) is a multicarrier modulation (MCM) technique that has emerged as a potential alternative to the widely used orthogonal frequency‐division multiplexing (OFDM) method.

Analog Single-Carrier Transmission with Frequency-Domain Equalization

IEICE Transactions on Communications, 2013
In this paper, a new analog signal transmission technique called analog single-carrier transmission with frequency-domain equalization (analog SC-FDE) is proposed. The proposed analog SC-FDE applies discrete Fourier transform (DFT), frequency-domain spectrum shaping and mapping, inverse DFT (IDFT), and cyclic prefix insertion before transmission.

Programmable Multi‐Axially Aligned Aerogels via Sequential Freeze‐Casting for Tailored Anisotropy and Tunable Mechanics

Advanced Science, EarlyView.
Conventional single‐gradient freeze‐casting typically produces unidirectional porous architectures with limited transverse connectivity. The Sequential Hybridization by Infiltration and Freeze‐casting Technique (SHIFT) addresses this constraint by integrating secondary aligned structures within a preformed primary scaffold.

Bioinspired Passive Flow Routing to Mitigate Thrombosis in Prosthetic Heart Valves and Cardiovascular Devices

Advanced Science, EarlyView.
Bioinspired passive flow routing mitigates thrombosis in cardiovascular devices by redirecting a small fraction of forward flow into stagnation‐prone regions. Inspired by avian alula and aircraft slat mechanisms, strategically placed routing channels restore washout around mechanical heart valves, reducing low‐shear exposure by four orders of magnitude

Single‐Atom Control of Aromaticity and Excited‐State Dynamics in Endohedral Zirconium–Antimony Zintl Clusters

Angewandte Chemie, EarlyView.
Single‐atom growth from [Zr@Sb12]2− to [Zr@Sb13]3− disrupts the closed‐shell S2P6 superatomic configuration and markedly attenuates three‐dimensional (3D) aromaticity. Ultrafast spectroscopy further links stronger spherical aromaticity to slower excited‐state relaxation, establishing an atom‐resolved structure‐aromaticity‐dynamics relationship ...

A Unifying Thermodynamic Model for Phase Separation and Aging of Biopolymers

Advanced Science, EarlyView.
Phase separation and aging of intrinsically disordered proteins are placed in a unifying framework. A thermodynamically consistent time‐dependent version of associating‐polymer theory shows how the processes are intricately coupled. Assuming aging to occur through interacting sites resulting from reversible conformational transitions, the model ...
