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.

Uniform CR Bound: Implementation Issues And Applications

open access: yes, 2008
We apply a uniform Cramer-Rao (CR) bound [1] to study the bias-variance trade-offs in single photon emission computed tomography (SPECT) image reconstruction.

MagmaFlow: A desktop platform for artificial intelligence‐driven expression analysis

open access: yesFEBS 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 ...

Uniform bounds for bounded geodesic image theorems [PDF]

open access: yesJournal für die reine und angewandte Mathematik (Crelles Journal), 2013
Abstract We give a universal bound for the bounded geodesic image theorem of Masur–Minsky. The proof uses elementary techniques. We also give a universal bound for a stronger version of subsurface projection, this demonstrates good control over many standard subsurface projections simultaneously.

Chaos vs. patience in a macroeconomic model of capital accumulation: New applications of a uniform neighborhood turnpike theorem [PDF]

open access: yes
We present in this paper some new results on the strong incompatibility between chaos and patience in a macroeconomic model of capital accumulation.

Tighter bound for MULTIFIT scheduling on uniform processors

open access: yes, 1991
We examine one of the basic, well studied problem of scheduling theory, that of nonpreemptive assignment of independent tasks on m parallel processors with the objective of minimizing the makespan.

A new flow chip in combination with multiphoton microscopy as a protocol for longitudinal 3D imaging of tissue calcification under shear stress

open access: yesFEBS Open Bio, EarlyView.
Miniaturized flow chip platform enabling continuous perfusion and longitudinal multiphoton 3D imaging of vascular smooth muscle cell constructs under physiological flow. Brightfield imaging guides region selection, while CellTracker Green and mRuby‐labeled fetuin‐A visualize cells and mineral deposition, respectively. Magnesium supplementation markedly

Asymptotic Elias Bound for Euclidean Space Codes over Uniform Signal Sets

open access: yes, 1999
We extend Piret's upper bound [1] to codes over uniform signal sets (a signal set is referred to be uniform if the Euclidean distance distribution is same from any point in the signal set) which include as a special case codes over symmetric PSK signal ...

A uniform error bound for the overrelaxation methods

open access: yes, 1997
Let Ax = b be a system of linear equations where A is symmetric and positive definite. Suppose that the associated block Jacobi matrix B is consistently ordered, weekly cyclic of index 2, and convergent [i.e., μ1 ≔ ϱ(B) < 1].

Convex approximations for totally unimodular integer recourse models: A uniform error bound [PDF]

open access: yes, 2015
We consider a class of convex approximations for totally unimodular (TU) integer recourse models and derive a uniform error bound by exploiting properties of the total variation of the probability density functions involved.
