Advanced Micro‐OLED Integration on Thin and Flexible Polymer Neural Probes for Targeted Optogenetic Stimulation

Advanced Functional Materials, EarlyView.
This paper introduces a flexible neural probe with integrated micro‐OLEDs on a flexible substrate for the first time, featuring 8 micro‐OLEDs and recording electrodes for optogenetics. It uses advanced encapsulation and an IAI anode for durability, emitting 470 nm light for ChR2 activation, enabling high‐resolution, minimally invasive stimulation ...

Coordination of photosynthetic traits across soil and climate gradients

Global Change Biology, Volume 29, Issue 3, Page 856-873, February 2023., 2023
Using an Australia‐wide photosynthetic trait dataset, we tested predictions from least‐cost optimality theory, which posits that plants balance nutrient use and water loss to optimize photosynthesis. We found that leaf nitrogen and rates of water loss co‐vary with one another in response to climate and to a lesser extent, soils.

Dynamic Spectrum Sharing for 5G NR and 4G LTE Coexistence - A Comprehensive Review

IEEE Open Journal of the Communications Society
In the early phase, the number of new radio (NR) users is considerably low compared to the long-term evolution (LTE) users. Hence, allocating the LTE spectrum to a small number of NR users will have a detrimental effect on the LTE users. To overcome this

A comprehensive study on the synchronization procedure in 5G NR with 3GPP-compliant link-level simulator

EURASIP Journal on Wireless Communications and Networking, 2023
The 5G New Radio synchronization procedure is the first step that the user must complete to access the mobile network. It mainly consists of the detection of the primary and secondary synchronization signals (PSS and SSS, respectively) and the decoding ...

Analytical TCP Model for Millimeter-Wave 5G NR Systems in Dynamic Human Body Blockage Environment

Sensors, 2020
Dynamic blockage of radio propagation paths between the user equipment (UE) and the 5G New Radio (NR) Base Station (BS) induces abrupt rate fluctuations that may lead to sub-optimal performance of the Transmission Control Protocol (TCP) protocol. In this

Research of 5G NR RedCap technology

Dianxin kexue, 2022
Faced to industrial wireless sensors, video surveillance, wearable devices, RedCap UE (reduced-capability user equipment) was proposed in 3GPP Release 17 (Rel-17), which could greatly reduce the costs of UE under the premise of satisfying the requirements of these use cases.Firstly, the standardization progress of 5G RedCap was introduced.Then, typical

Cost of Increased Bandwidth Efficiency in 5G NR

2017 IEEE 86th Vehicular Technology Conference (VTC-Fall), 2017
In this paper, subband filtered CP-OFDM and windowed CP-OFDM waveforms proposed for 5G new radio (NR) are compared to LTE-like downlink and uplink waveforms under different power amplifier (PA) models. The effects of subband filtering or windowing are evaluated in terms of out-of-band and inband emissions, average error vector magnitude (EVM) and ...

Advances in Radiative Heat Transfer: Bridging Far‐Field Fundamentals and Emerging Near‐Field Innovations

Advanced Functional Materials, EarlyView.
This review synthesizes the evolution of radiative heat transfer, emphasizing the transition from far‐field to near‐field regimes. Traditional frameworks, such as Planck's law, are revisited alongside modern innovations like fluctuational electrodynamics. Applications span nanoscale thermal management, energy harvesting, and thermophotovoltaic systems.
