A Novel Approach to Mitigate Blade-to-Blade Interactions in Vertical-Axis Wind Turbines Suitable for Urban Areas

open access: yesComputation
With the growth of urban zones and the increasing need for energy, the use of renewable energy solutions in the built environment becomes a must. Due to their small size and the ability to capture wind from any direction, vertical-axis wind turbines are ...

Comparative assessment of crystallographic and cryo‐EM models in the Protein Data Bank

open access: yesFEBS Open Bio, EarlyView.
Raw data obtained by X‐ray crystallography or cryo‐EM result in experimental maps, ultimately fitted by atomic models. Although the physical principles are different, the final results can be viewed, compared, and evaluated in the same way. With cryogenic electron microscopy (cryo‐EM) on track to surpass X‐ray crystallography as the preferred method ...

Recurrences for sums of powers of binomial coefficients

open access: yesJournal of Combinatorial Theory, Series A, 1989
Let \(S_ n^{(r)}=\sum^{n}_{k=0}\left( \begin{matrix} n\\ k\end{matrix} \right)^ r\) \((r=1,2,...)\). An elementary method is given for finding recurrence relation for \(S_ n^{(r)}\) with \([(r+3)/2]\) terms. This confirms a conjecture of Franel. This method could easily be implemented on a computer and would require vastly less computation than ...

Elevated Connectivity During Language Processing Is Associated With Cognitive Performance in SeLECTS

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Self‐Limited Epilepsy with Centrotemporal Spikes (SeLECTS) is associated with language impairments despite seizures originating in the motor cortex, suggesting aberrant cross‐network interactions. Here we tested whether functional connectivity in SeLECTS during language tasks predicts language performance.

Performance of Microscale Maple Seed Wind Turbine Blade

open access: yesEnergies
Strategies to reduce global warming by limiting the consumption of fossil fuels are expected in part to include the integration of various renewable energies in residential buildings, which emit a considerable volume of greenhouse gases.

The Impact of Increasing the Number of Undulations in the Undulatory Shape Distributed Along the Concave Surface of a Savonius Wind Turbine Blade Inspired by the Flower of Life Concept [PDF]

open access: yesE3S Web of Conferences
In our latest research, we investigated the incorporation of an undulatory pattern along the concave surface of Savonius turbine blades. This study builds upon our previous findings, where we examined the effects of varying undulation counts across four ...

Relationship Between Neurologic Symptoms and Signs and FMR1 Genotype in Premutation Carriers

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background and Objectives Fragile X‐associated Tremor/Ataxia Syndrome (FXTAS) is the most severe late‐onset condition caused by a premutation in the FMR1 gene, characterized by expanded CGG triplet repeats of 55–200. Clinical presentations of FXTAS, including gait ataxia, kinetic tremor, cognitive decline, and rare Parkinsonism, are linked to ...

Aerodynamic enhancement and wake recovery of an asymmetric dual-rotor wind turbine: a coupled-dual rotor wake modelling and CFD investigation

open access: yesEngineering Applications of Computational Fluid Mechanics
This study proposes a novel asymmetric coaxial counter-rotating dual-rotor wind turbine (A-DRWT). Based on the asymmetric configuration of the A-DRWT, this study develops a Coupled-Dual Rotor (CDR) wake model by extending the Gaussian-distribution-based ...
