A note on Catalan numbers associated with p-adic integral on Zp [PDF]
Proceedings of the Jangjeon Mathematical Society, Vol 19(2016),
no. 3, 2016 In this paper, we study Catalan numbers which can be represented by the p-adic integral on Zp and we investigate some properties and formulae related to Catalan numbers and special numbers.

Ara es l’hora? The Approach of the Catalan Political Scene to Independence Issues
Historia i Polityka, 2016 The political situation in Catalonia during the last months is changing almost daily. Catalan nationalist movements consistently continue their efforts to create an independent state. As a result, every vote – an unofficial plebiscite, local elections or

Catalan pairs and Fishburn triples [PDF]
arXiv, 2015 Disanto, Ferrari, Pinzani and Rinaldi have introduced the concept of 'Catalan pair', which is a pair of partial orders (S,R) satisfying certain axioms. They have shown that Catalan pairs provide a natural description of objects belonging to several classes enumerated by Catalan numbers. In this paper, we first introduce another axiomatic structure (T,

Molecular Ecology Resources, EarlyView., 2023 Abstract A high‐quality reference genome can be a valuable resource for threatened species by providing a foundation to assess their evolutionary potential to adapt to future pressures such as environmental change. We assembled the genome of a female hihi (Notiomysits cincta), a threatened passerine bird endemic to Aotearoa New Zealand.

Arithmetic of weighted Catalan numbers [PDF]
arXiv, 2019 In this paper, we study arithmetic properties of weighted Catalan numbers. Previously, Postnikov and Sagan found conditions under which the $2$-adic valuations of the weighted Catalan numbers are equal to the $2$-adic valutations of the Catalan numbers. We obtain the same result under weaker conditions by considering a map from a class of functions to $

Photoinduced Hydrogen Evolution Catalyzed by Co(II) Complexes of N5‐Donor Ligands
Chemistry – A European Journal, EarlyView.Cobalt(II) complexes of three related pentadentate ligands have been investigated as photoelectrochemical catalysts for proton reduction/hydrogen gas evolution in the presence of ruthenium, iridium, or copper‐based photosensitizers. Potential mechanisms for hydrogen evolution have been investigated by time‐resolved transient absorption spectroscopy and

The Hessenberg matrices and Catalan and its generalized numbers [PDF]
arXiv, 2018 We present determinantal representations of the Catalan numbers, k-Fuss-Catalan numbers, and its generalized number. The entries of the normalized Hessenberg matrices are the binomial coefficients that related with the enumeration of lattice paths.

Directional Macrocycle Transport, Release and Recapture enabled by a Rotaxane Transporter
Chemistry – A European Journal, Accepted Article.A transporter for a directional macrocycle transport, release and recapture was constructed. This was achieved using a rotaxane featuring a dibenzo‐24‐crown‐8 macrocycle, dibenzylammonium (DBA)/methyl triazolium (MTA) stations on the thread and anthracene/triisopropylsilyl‐acetylene stoppers, respectively.
