Reduced Persistence Length and Fluctuation-Induced Interactions of Directed Semiflexible Polymers on Fluctuating surfaces

, 1996
We consider directed semiflexible polymers embedded in a fluctuating surface which is governed by either surface tension or bending rigidity. The attractive interactions induced by the fluctuations of the surface reduce the rigidity of the polymers.

Partition Border Tuning and Chattering Mitigation for DC–DC Series Resonant Converters: A Stability‐Oriented Approach

IET Circuits, Devices &Systems, Volume 2026, Issue 1, 2026.
Typical resonant converter controllers are based on linearised averaged models, which have significant modelling errors when there are wide fluctuations in the input voltage, load and reference voltages. In this article, a piecewise affine (PWA) switching surface with active border tuning of affine sections, called the Partition Border Tuning (PBT ...

Pathways to a Fully Renewable Energy System in Iran: A Scenario‐Based Analysis Across Power, Heat, Transport, Industry and Desalination

IET Renewable Power Generation, Volume 20, Issue 1, January/December 2026.
This study assesses three transition pathways for Iran's energy system to 2050. Only the best policy scenario (BPS) achieves 100% renewables, with over 93% of primary energy from solar photovoltaics, extensive storage, and power‐to‐X technologies. In the BPS, CO2 emissions fall to zero and the levelised cost of electricity declines to €24.7/MWh by 2050.

Revised phylogeny of the Inula complex group (Asteraceae: Inuleae) with a recircumscription of Carpesium and establishment of a new genus Cladocarpesium

Journal of Systematics and Evolution, Volume 64, Issue 1, Page 95-105, January 2026.
Cladocarpesium T. Deng & Qun Liu, gen. nov. (separated from Carpesium) is established with Cladocarpesium abrotanoides (L.) T. Deng & Qun Liu designated as the type species. The new genus is morphologically distinguished from Carpesium s.str. by its sympodial growth form (typically producing three branches), sessile capitula, and three‐seriate ...

Evaluation of Different Doses of Tanacetum parthenium Extract (TPE) on Blood Biochemical Parameters and Oxidative Stress Liver Biomarkers of Fish

Aquaculture Research, Volume 2026, Issue 1, 2026.
Although medicinal plants can be used to reduce stress caused by transportation and handling and to prevent and treat certain diseases in fish, evaluating their safety for fish is essential before their use. This study aimed to evaluate the pharmacological effects and determine the safe dose of the Tanacetum parthenium (known as feverfew) extract (TPE)
