Recurrences for sums of powers of binomial coefficients
Journal 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 ...

FEBS Open Bio, EarlyView.The dFoCC pipeline starts with observed DED and resting‐state coordinates, which are then used to generate a library of triggered states. Correlation analysis of the calculated DED features of each candidate vs observed DED permits quantitative evaluation of candidate structural quality.

MagmaFlow: A desktop platform for artificial intelligence‐driven expression analysis
FEBS Open Bio, EarlyView.MagmaFlow is a free, no‐code platform for gene expression analysis. It generates interactive volcano plots, links genes to literature, pathways, and diseases, prioritizes candidates using millions of publications, identifies affected biological processes, builds network diagrams, and exports publication‐ready figures and reports for macOS and Windows ...

FEBS Open Bio, EarlyView.NMR metabolomics revealed concentration‐dependent metabolic perturbations in HepG2 cells exposed to H2O2. Rifampicin pretreatment enhanced metabolic competence, attenuated toxin‐induced alterations and produced metabolite profiles more consistent with human liver physiology, supporting the use of CYP450‐induced HepG2 models for improved in vitro ...

Optimizing photoexcitation conditions for time‐resolved X‐ray solution scattering experiments
FEBS Open Bio, EarlyView.Time‐resolved X‐ray solution scattering (TR‐XSS) is a powerful technique to visualize how proteins change their structure in real time after light activation. Selecting the right laser photoexcitation conditions—fluence, excitation geometry, and sample refresh rate—is critical to maximize the experimental signal while avoiding unwanted side effects ...

A Comparative Review of Vertical Axis Wind Turbine Designs: Savonius Rotor vs. Darrieus Rotor
InventionsThis paper reviews and analyzes three types of vertical-axis wind rotors: the classic Savonius, spiral Savonius, and Darrieus designs. Using numerical modeling methods, including computational fluid dynamics (CFD), their aerodynamic characteristics ...

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]
E3S Web of ConferencesIn 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 ...

Evolution‐guided yeast complementation reveals functional differences in human PSPH variants
FEBS Open Bio, EarlyView.Ancient genomes can help guide which human genetic variants are tested experimentally. This study applies that idea to PSPH, a gene involved in serine biosynthesis, and uses high‐throughput yeast complementation to compare variant function. The findings reveal measurable differences among selected alleles and illustrate the value of evolution‐guided ...

Design and numerical analysis of an efficient H-Darrieus vertical-axis hydrokinetic turbine
Journal of Mechanical Engineering and Sciences, 2019 Hydrokinetic turbines are one of the technological alternatives to generate and supply electricity for rural communities isolated from the national electrical grid with almost zero emission. The Darrieus turbine is one of the options that can be used as
