The complex title salt, (C21H20OP)2[CoCl4], is the reaction product of CoCl2 with acetonyltri-phenyl-phospho-nium chloride in aceto-nitrile. In the anion, the Co(II) atom exhibits a typical tetra-hedral environment, with Co-Cl distances ranging from 2.2721 (6) to 2.2901 (6) Å, and with Cl-Co-Cl angles ranging from 106.12 (2) to 112.24 (2)°. The two phospho-nium cations likewise show the expected tetra-hedral configuration, with P-C distances ranging from 1.785 (2) to 1.8059 (18) Å and C-P-C angles ranging from 106.98 (8) to 112.85 (15)°. The mol-ecules inter-act in the lattice mainly through Coulombic and van der Waals forces because there is no particular polarity to the charges carried by the cations or anion. In the crystal, the cations and anions are arranged in sheets parallel to (001).

Odours released by objects in natural environments can contain information about their spatial locations. In particular, the correlation of odour concentration timeseries produced by two spatially separated sources contains information about the distance between the sources. For example, mice are able to distinguish correlated and anti-correlated odour fluctuations at frequencies up to 40 Hz, while insect olfactory receptor neurons can resolve fluctuations exceeding 100 Hz.

Detecting directional couplings from time series is crucial in understanding complex dynamical systems. Various approaches based on reconstructed state-spaces have been developed for this purpose, including a cross-distance vector measure, which we introduced in our recent work. Here, we devise two new cross-vector measures that utilize ranks and time series estimates instead of distances.

Long-range axons are fundamental to brain connectivity and functional organization, enabling communication between different brain regions. Recent advances in experimental techniques have yielded a substantial number of whole-brain axonal reconstructions. While previous computational generative models of neurons have predominantly focused on dendrites, generating realistic axonal morphologies is more challenging due to their distinct targeting.

Coronaviruses (CoVs) encode non-structural proteins (nsp's) 1-16, which assemble to form replication-transcription complexes that function in viral RNA synthesis. All CoVs encode a proofreading 3'-5' exoribonuclease in non-structural protein 14 (nsp14-ExoN) that mediates proofreading and high-fidelity replication and is critical for other roles in replication and pathogenesis. The enzymatic activity of nsp14-ExoN is enhanced in the presence of the cofactor nsp10.
