Constrained Global Optimization by Smoothing

open access: yes
This paper proposes a novel technique called "successive stochastic smoothing" that optimizes nonsmooth and discontinuous functions while considering various constraints. Our methodology enables local and global optimization, making it a powerful tool for many applications.

A light‐triggered Time‐Resolved X‐ray Solution Scattering (TR‐XSS) workflow with application to protein conformational dynamics

open access: yesFEBS Open Bio, EarlyView.
Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

Optimality Theory and Minimalism: A Possible Convergence?

open access: yes, 2006
This issue of Linguistics in Potsdam contains a number of papers that grew out of the workshop Descriptive and Empirical Adequacy in Linguistics held in Berlin on December 17-19 December, 2005.

Analysing the significance of small conformational changes and low occupancy states in serial crystallographic data

open access: yesFEBS Open Bio, EarlyView.
This protocol paper outlines methods to establish the success of a time‐resolved serial crystallographic experiment, by means of statistical analysis of timepoint data in reciprocal space and models in real space. We show how to amplify the signal from excited states to visualise structural changes in successful experiments.

Refinement of amino‐acid conformation vs. difference density maps in time‐resolved serial femtosecond crystallography data analysis

open access: yesFEBS 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.

Derivational Phonology and Optimality Phonology: Formal Comparison and Synthesis

open access: yes, 2003
This thesis conducts a formal comparison of Optimality Theoretic phonology with its predecessor, Rule-based Derivational phonology. This is done in three studies comparing (i) rule operations and Faithfulness constraint violations, (ii) serial rule ...

Aquaporin‐3 and aquaporin‐5 impact the development of pancreatic ductal adenocarcinoma spheroids

open access: yesFEBS Open Bio, EarlyView.
Schematic representation of the role of aquaporin‐3 (AQP3) and aquaporin‐5 (AQP5) in pancreatic ductal adenocarcinoma (PDAC). Both proteins are upregulated in PDAC and are associated with tumor progression and metastatic potential. Silencing AQP3 or AQP5 in PDAC spheroids results in decreased diameter, area, and overall growth, underscoring their key ...

Optimality Theory and the Minimalist Program

open access: yes, 2006
In this paper I argue that an OT-approach to grammar is actually essential to minimalist investigations, because it dramatically widens the set of linguistic properties potentially reducible to interface conditions while at the same time dispensing with ...

A new analytical envelope for multivariate global optimization

open access: yesJournal of Numerical Analysis and Approximation Theory
We propose a new global optimization method that combines an α–dense univariate reduction with explicitly constructed analytical envelopes: a piecewise concave underestimator (PCU) and a piecewise convex overestimator (PCO).

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.
