Patterns in matchings and rook placements [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2013
Extending the notion of pattern avoidance in permutations, we study matchings and set partitions whose arc diagram representation avoids a given configuration of three arcs.

Assessing the scientific value and vulnerability of paleontological sites: a new analytic operational procedure

open access: yesFrontiers in Earth Science, 2023
Introduction: Paleontological heritage rarely receives the same legislative attention as archeological heritage. Part of the problem seems to be, at least in some contexts (e.g., Italy), the difficulty of acknowledging fossils as distinct assets from ...

Triplet‐Triplet Annihilation Enhances Photochemical Curing Contrast for Vat‐Based 3D Printing

open access: yesAdvanced Functional Materials, EarlyView.
Triplet–triplet annihilation photopolymerization (TTAP) resins enhance curing contrast for digital light processing (DLP) 3D printing compared to conventional Type I and II photopolymerizations at matched optical densities. By exploiting a superlinear initiation response, TTAP preserves fine details, allowing reliable fabrication of complex structures ...

Elucidating the Role of Surface Ligands on the Oxidative Etching of Au Bipyramids During Photothermia Using Liquid Cell Transmission Electron Microscopy

open access: yesAdvanced Functional Materials, EarlyView.
Gold bipyramids can act as efficient plasmonic nanoheaters, but they often reshape during laser heating. This study shows that oxygen nanobubbles drive oxidative etching and that surface ligands control stability. CTAB‐ and citrate‐coated particles blunt and lose optical performance, whereas polystyrene sulfonate preserves shape and heating by ...

Unlocking Photodetection Mode Switching from a Simple Lateral Design

open access: yesAdvanced Functional Materials, EarlyView.
A simple lateral 2D perovskite photodetector capable of switching among transient, continuous, and dual transient/continuous photoresponse modes is achieved by integrating photoconductive effects with capacitive coupling from the SiO2/Si substrate. Such light‐programmable photodetection mode switching enables triple‐channel information transmission and

A NEW FIND OF OREOPITHECUS (MAMMALIA, PRIMATES) IN THE BACCINELLO BASIN (GROSSETO, SOUTHERN TUSCANY)

open access: yesRivista Italiana di Paleontologia e Stratigrafia, 2017
A mandible of Oreopithecus cf. bambolii was found in Miocene sediments of the Baccinello basin (Grosseto, Tuscany). It confirms, unequivocally, the occurrence of this peculiar primate in the V2 mammal fauna of the basin. This find allows some comments on

Should great apes have 'human rights'? [PDF]

open access: yes, 2009
Celebrating 60 years of the Universal Declaration of Human Rights provides an opportune moment to ask whether it is time for the other great apes to be granted ‘human rights’.

Rook Theory andt-Cores

open access: yesJournal of Combinatorial Theory, Series A, 1998
Given a partition \(\lambda\), we define \(r_k(\lambda)\) to be the number of ways of placing \(k\) rooks on the Young diagram of \(\lambda\) so that no two rooks are in the same row or column. Two partitions, \(\lambda\) and \(\mu\), are said to be rook equivalent if \(r_k(\lambda) = r_k(\mu)\) for all \(k\). A partition \(\lambda\) is a \(t\)-core if

Ferroelectric Quantum Dots for Retinomorphic In‐Sensor Computing

open access: yesAdvanced Materials, EarlyView.
This work has provided a protocol for fabricating retinomorphic phototransistors by integrating ferroelectric ligands with quantum dots. The resulting device combines ferroelectricity, optical responsiveness, and low‐power operation to enable adaptive signal amplification and high recognition accuracy under low‐light conditions, while supporting ...
