Determinising Parity Automata [PDF]
, 2014 Parity word automata and their determinisation play an important role in automata and game theory. We discuss a determinisation procedure for nondeterministic parity automata through deterministic Rabin to deterministic parity automata. We prove that the

Advanced Materials, EarlyView.A linker‐desymmetrization‐modulator‐compensation (LDMC) strategy for constructing structurally diverse Zr‐MOFs is reported. This approach reduces linker symmetry to create defects in Zr‐clusters, which can be compensated for by modulator coordination. Using this approach, we synthesized PCN‐1005 and PCN‐1006, featuring unprecedented Zr‐clusters. In PCN‐

When Should You Adjust Standard Errors for Clustering?
, 2017 In empirical work in economics it is common to report standard errors that account for clustering of units. Typically, the motivation given for the clustering adjustments is that unobserved components in outcomes for units within clusters are correlated.

Probabilistic Computability and Choice [PDF]
, 2015 We study the computational power of randomized computations on infinite objects, such as real numbers. In particular, we introduce the concept of a Las Vegas computable multi-valued function, which is a function that can be computed on a probabilistic ...

Advanced Materials Interfaces, EarlyView.xx xx. ABSTRACT Diabetic foot ulcer (DFU) is a chronic complication of diabetes, primarily caused by hyperglycemia, peripheral vascular disease, and neuropathy. Characterized by persistent hyperglycemia, impaired perfusion, inflammation, and infection, DFUs pose significant challenges to healing and are associated with high morbidity and amputation ...

Angewandte Chemie, EarlyView.Multi‐crystal X‐ray diffraction (MCXRD) methods allow accurate structural characterisation with crystals too small for single‐crystal X‐ray diffraction and too large for electron diffraction, as demonstrated here for metal‐organic frameworks, and alleviate the radiation‐induced chemical changes that can result from using high‐intensity X‐ray sources to
