ChemPhysChem, Volume 27, Issue 8, 28 April 2026.For directly comparing experimental results on gas‐phase ion reactions with the predictions from quantum chemical calculations, the latter must first be converted into rate constants. This review addresses the question of whether current methods of statistical rate theory can accomplish this task reliably. Statistical rate theory has long been used for

Advanced Photonics Research, Volume 7, Issue 3, March 2026.This article proposes a deep learning (DL) approach for modeling and optimizing frequency‐doubled radio‐over‐fiber links. By collectively replacing traditional components with DL model, accurate system evaluation is achieved. Moreover, through an end‐to‐end architecture, performance optimization is accomplished.

Clinical Case Reports, Volume 14, Issue 2, February 2026.ABSTRACT Papillorenal syndrome (PAPRS), or renal coloboma syndrome, is a rare autosomal dominant disorder caused by PAX2 mutations. It classically manifests with renal hypodysplasia and optic nerve anomalies. However, recent literature suggests an expanding phenotypic spectrum.

Perbandingan PAPR Metode CSLM dan SSLM pada Pengirim OFDM
Jurnal Nasional Teknik Elektro dan Teknologi Informasi, 2019 OFDM has multiple weaknesses, one of which is a high Peak to Power Average (PAPR). The maximum power value of the OFDM signal will be much greater than the average power, so the efficiency of the amplifier will be reduced.

International Journal of Satellite Communications and Networking, Volume 44, Issue 1, Page 73-88, January/February 2026.The potential gains of NOMA were evaluated in a satellite system with heterogeneous receivers, after considering the use of specific DVB‐S2X MODCODs, along with the impact of non‐linearities. It was concluded that a judicious power allocation in NOMA, jointly optimized with the IBO of the PAs, can yield significant sum‐rate gains.
