An Improved Greedy Algorithm for Subset Selection in Linear Estimation

Dutta, Shamak (author), Wilde, N. (author), Smith, Stephen L. (author)

In this paper, we consider a subset selection problem in a spatial field where we seek to find a set of k locations whose observations provide the best estimate of the field value at a finite set of prediction locations. The measurements can be taken at any location in the continuous field, and the covariance between the field values at...

Biochemistry shapes growth kinetics of nitrifiers and defines their activity under specific environmental conditions

Martinez-Rabert, Eloi (author), Smith, Cindy J. (author), Sloan, William T. (author), Gonzalez Cabaleiro, R. (author)

Is it possible to find trends between the parameters that define microbial growth to help us explain the vast microbial diversity? Through an extensive database of kinetic parameters of nitrifiers, we analyzed if the dominance of specific populations of nitrifiers could be predicted and explained. We concluded that, in general, higher growth...

Closed-loop active object recognition with constrained illumination power

Noom, J. (author), Soloviev, O.A. (author), Smith, C.S. (author), Verhaegen, M.H.G. (author)

Some applications require high level of image-based classification certainty while keeping the total illumination energy as low as possible. Examples are minimally invasive visual inspection in Industry 4.0, and medical imaging systems such as computed tomography, in which the radiation dose should be kept “as low as is reasonably achievable”...

SOLEIL: Single-objective lens inclined light sheet localization microscopy

Hung, S. (author), Cnossen, J.P. (author), Fan, D. (author), Siemons, Marijn (author), Jurriens, Daphne (author), Grußmayer, K.S. (author), Soloviev, O.A. (author), Kapitein, Lukas C. (author), Smith, C.S. (author)

High-NA light sheet illumination can improve the resolution of single-molecule localization microscopy (SMLM) by reducing the background fluorescence. These approaches currently require custom-made sample holders or additional specialized objectives, which makes the sample mounting or the optical system complex and therefore reduces the...

Overcoming Nitrogen Reduction to Ammonia Detection Challenges: The Case for Leapfrogging to Gas Diffusion Electrode Platforms

Kolen, M. (author), Ripepi, D. (author), Smith, W.A. (author), Burdyny, T.E. (author), Mulder, F.M. (author)

The nitrogen reduction reaction (NRR) is a promising pathway toward the decarbonization of ammonia (NH3) production. However, unless practical challenges related to the detection of NH3 are removed, confidence in published data and experimental throughput will remain low for experiments in aqueous electrolyte. In this perspective, we analyze...

Global correction of optical distortions in multicolor single-molecule microscopy using Zernike polynomial gradients

Mc Cluskey, K.A. (author), van Veen, E.N.W. (author), Cnossen, J.P. (author), Wesselink, W.J. (author), Asscher, F.M. (author), Smith, C.S. (author), Dekker, N.H. (author)

Accurate image alignment is critical in multicolor single-molecule fluorescence microscopy. Global alignment using affine transformations leaves residual errors due to the nonlinearity of the distortions, which decreases the effective field of view. Subsequent local refinement demands either large amounts of reference data and processing time...

Yang, K. (author), Li, Mengran (author), Subramanian, S.S. (author), Blommaert, M.A. (author), Smith, W.A. (author), Burdyny, T.E. (author)

Advancing reaction rates for electrochemical CO2 reduction in membrane electrode assemblies (MEAs) have boosted the promise of the technology while exposing new shortcomings. Among these is the maximum utilization of CO2, which is capped at 50% (CO as targeted product) due to unwanted homogeneous reactions. Using bipolar membranes in an MEA ...

Role of the Carbon-Based Gas Diffusion Layer on Flooding in a Gas Diffusion Electrode Cell for Electrochemical CO₂ Reduction

Yang, K. (author), Kas, Recep (author), Smith, W.A. (author), Burdyny, T.E. (author)

The deployment of gas diffusion electrodes (GDEs) for the electrochemical CO2 reduction reaction (CO2RR) has enabled current densities an order of magnitude greater than those of aqueous H cells. The gains in production, however, have come with stability challenges due to rapid flooding of GDEs, which frustrate both laboratory experiments and...

Orientation of a bipolar membrane determines the dominant ion and carbonic species transport in membrane electrode assemblies for CO₂reduction

Blommaert, M.A. (author), sharifian, rezvan (author), Shah, N. (author), Nesbitt, N.T. (author), Smith, W.A. (author), Vermaas, D.A. (author)

A bipolar membrane (BPM), consisting of a cation and an anion exchange layer (CEL and AEL), can be used in an electrochemical cell in two orientations: reverse bias and forward bias. A reverse bias is traditionally used to facilitate water dissociation and control the pH at either side. A forward bias has been proposed for several...
