A Space-Time Spreading Assisted Multicarrier DS-CDMA System using OVSF Codes Employing Adaptive Mode Switching Thresholds and Adaptive Modulation

, 2005
The Concept of Space-Time Spreading (STS) assisted, Adaptive Quadrature Amplitude Modulation (AQAM) aidedMC DS-CDMAis introduced. The AQAMmode-switching thresholds are determined using an on-line real-time Bit-Error-Ratio (BER) based learning procedure ...

Correlation‐Driven d‐Band Modifications Promote Chemical Bonding at 3d‐Ferromagnetic Surfaces

Small, EarlyView.
Electron correlation at the oxygen‐passivated Fe(100) surface renormalizes and narrows the Fe d‐bands, enhancing their energetic overlap with the frontier orbitals of adsorbed pentacene. This strengthens hybridization and converts a weakly bound interface into a chemisorbed hybrid system, illustrating how correlation‐tuned d‐bands can be used to ...

MnBr2${\rm MnBr}_2$ on the Graphene on Ir(110) Substrate: Growth, Structure, and Super‐Moiré

Small, EarlyView.
The study realizes single‐layer MnBr2${\rm MnBr}_2$ via molecular beam epitaxy on graphene on Ir(110), unveiling a unique super‐moiré (“moiré of moirés”) formed by lattices of different symmetries. Remarkably, this super‐moiré is driven by a virtual interaction between non‐contacting layers.

Strategic Spatial Segregation in Silicon Photoelectrodes: Decoupling Catalytic and Optical Functions for High‐Efficiency Solar Water Splitting

Small Structures, Volume 6, Issue 5, May 2025.
A novel spatial segregation strategy for silicon photoelectrodes is demonstrated, where catalyst wires surrounded by tapered microwires effectively decouple competing optical and catalytic requirements. This architectural innovation enables optimal light absorption and catalytic activity while maintaining efficient charge transport, achieving 96.5 ...

Universal Fabrication of Graphene/Perovskite Oxide Hybrid Heterostructures

Small Structures, EarlyView.
This study presents a universal, catalyst‐free method for the direct growth of monolayer graphene on perovskite oxides without the need for transfer. The process yielded uniform graphene formation across different insulating substrates under identical conditions, revealing a substrate‐independent growth mechanism.

Creating “Reflect‐ables”: A Conversation Analytic Study of Feedback Practices in Language Teacher Education

TESOL Quarterly, EarlyView.
ABSTRACT This study examines how second language (L2) teacher educators provide feedback on student teachers' (STs) microteaching performances. Although conversation analysis (CA) research has extensively analyzed classroom interaction, there has been limited focus on how CA‐specialized teacher educators shape STs' classroom interactional competence ...
