Polarization‐resolved femtosecond Vis/IR spectroscopy tailored for resolving weak signals in biological samples using minimal sample volume

open access: yesFEBS Open Bio, EarlyView.
Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐

Directed evolution of enzymes at the crossroads of tradition and innovation

open access: yesFEBS Open Bio, EarlyView.
An iterative cycle of data‐driven enzyme optimization comprising four stages: genetic diversification of a template enzyme, expression of protein variants, high‐throughput evaluation, and machine‐learning‐guided redesign of the next variant library.

Applications of Taguchi Methods in Prestressed Concrete Structures [PDF]

open access: yes预应力技术
Prestressed concrete (PSC) structures are fundamental to bridges, buildings, and other critical infrastructure, requiring design approaches that balance mechanical performance, durability, and cost throughout the service life. Because PSC systems involve

On incomplete orthogonal arrays

open access: yesJournal of Combinatorial Theory, Series A, 1985
\textit{E. T. Parker} [Proc. Am. Math. Soc. 13, 219-221 (1962; Zbl 0105.015)] remarked that if an incomplete orthogonal array with parameters (1,r,s,k,2) exists then \(s\geq (r-1)k\). As the author shows, this result is easily extended to incomplete orthogonal arrays (1,r,s,k,t) for which \(s\geq (r-t+1)k\). \textit{K. A. Bush} [Ann. Math.

Optimizing photoexcitation conditions for time‐resolved X‐ray solution scattering experiments

open access: yesFEBS 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 ...

Orthogonal Genetic Algorithm for Planar Thinned Array Designs

open access: yesInternational Journal of Antennas and Propagation, 2012
An orthogonal genetic algorithm (OGA) is applied to optimize the planar thinned array with a minimum peak sidelobe level. The method is a genetic algorithm based on orthogonal design.

Feasibility of Orthogonal Taguchi Arrays for Determining Parameter Trends in MDT

open access: yesCurrent Directions in Biomedical Engineering
Huge parameter studies are usually conducted to optimize and characterize systems for steering magnetic nanoparticles in magnetic drug targeting (MDT). Thus, many simulations or measurements are needed to determine the system which is time-consuming and ...

On existence and number of orthogonal arrays

open access: yesJournal of Combinatorial Theory, Series A, 1988
The authors show that for significantly large \(\lambda\) an orthogonal array \(A_ t(v,k,\lambda)\) exists for all (v,k,\(\lambda\),t) and that a signed orthogonal array \(SA_ t(v,k,t)\) exists for all (v,k,\(\lambda\),t), \(k\geq t\). As in \textit{N. M. Singhi} and \textit{S. S. Shrikhande} [A reciprocity relation for t-designs, Eur. J. Comb.
