Reaching the Betz limit via the Newton's method for one (1)-dimensional optimisation

Applied Mathematical Sciences
The $Betz$ theory states that a horizontal axis wind turbine can only extract less than $\frac{16}{27}$ ($59.3\%$) of the kinetic energy of the wind. The value $\frac{16}{27}$ ($0.\overline{592}$) is called the $Betz$ limit. In $1919$, $Albert$ $Betz$ used a method that is analytic to derive the $Betz$ theory and henceforth finding the $Betz$ limit. In

A Joint Venture? The Ideological Foundations of the Populist Radical Right's Economic Agenda Beyond Welfare Policies

Swiss Political Science Review, EarlyView.
Abstract Recently, the socio‐economic agenda of populist radical right parties (PRRPs) has attracted growing scholarly interest, yet many studies focus specifically on positions on welfare policies. It is often argued that economic issues are of secondary importance to PRRPs, or that their positions are deliberately blurred to maximize electoral appeal.

Performance analysis of diffuser-augmented wind turbines with swept rotor

Global Energy Interconnection
This work presents a novel performance analysis model of diffuser-augmented wind turbines (DAWT) with swept blades, considering the influence of diffuser efficiency and thrust. Blade element momentum theory (BEMT) is extended to incorporate the effect of

Theoretical calculation of wind (Or water) turbine considering kinetic and potential energy to exceed the Betz limit

The Betz limit sets a theoretical upper limit for the energy efficiency of turbines with a maximum power coefficient of 16/27. Betz's theory is precise and based on the calculation of kinetic energy. However, if the potential energy is taken into account the theoretical energy efficiency of a turbine can be higher.

The Role of Lightning in Atmospheric Chemistry

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 16, 28 August 2026.
Abstract Lightning has important effects on atmospheric constituents in primarily the middle and upper troposphere. We summarize the effects of lightning on atmospheric chemistry that have been published since the last major review in 2007. The estimates of NOx production by lightning (LNOx) are based on five methods: theoretical/laboratory estimates ...

Anti‐CD19 CAR T Cells in Autoimmune Encephalitis: Inflammation Controlled, Neurodegeneration Unchecked?

Annals of Clinical and Translational Neurology, Volume 13, Issue 8, Page 1697-1701, August 2026.
ABSTRACT Just recently, successful chimeric antigen receptor (CAR) T cell therapy was reported in the first patient with refractory, anti‐diacylglycerol lipase alpha (DAGLA) antibody‐mediated autoimmune encephalitis, achieving partial clinical remission.

Analysis of glutamine synthetase target‐site mutations and their role in endowing glufosinate‐ammonium resistance

Pest Management Science, Volume 82, Issue 8, Page 7633-7644, August 2026.
GS2.2 G255D mutation conferred enzyme‐level glufosinate insensitivity but no whole‐plant resistance, showing trade‐offs between catalytic function and herbicide binding and providing a baseline for future studies on target‐site glufosinate resistance.

Hot Injection Synthesis of Ultrathin Bi2Se3 Nanosheets With Controllable Dimensions

Small Methods, Volume 10, Issue 15, 7 August 2026.
Graphic of hot‐injection method for synthesizing Bi2Se3${\rm Bi}_2{\rm Se}_3$ nanoplatelets of controlled shape, thickness, and lateral size. The ultra‐thin regime is achievable, which is interesting for studying topological phase transitions. ABSTRACT In this work, a synthesis method for colloidal nanoplatelets (NPLs) of the topological insulator ...

Theoretical efficiency of a wind turbine in non-uniform base flow: Revisiting the Betz–Joukowsky limit

Physics of Fluids
Classical one-dimensional momentum theory suggests that there is an upper limit to the power that can be extracted from the available wind resource. In the present work, we relax the assumption of constant velocity and investigate how the power efficiency of a turbine is affected by a non-uniform velocity field in the base flow. The analysis shows that

Unravelling the Significance of Cystatin C and Bunina Bodies in Amyotrophic Lateral Sclerosis Pathogenesis

Neuropathology and Applied Neurobiology, Volume 52, Issue 4, August 2026.
ABSTRACT Amyotrophic lateral sclerosis (ALS), also known as motor neuron disease (MND), is a fatal neurodegenerative disease primarily affecting motor neurons. Two key protein inclusions found in lower motor neurons serve as neuropathological hallmarks of the disease in human tissue: the TDP43‐positive inclusion and the cystatin C‐positive Bunina body.
