Nearly 180° Field‐of‐View Metalens for Miniaturized Imaging Systems

open access: yesLaser &Photonics Reviews, EarlyView.
A compact, single‐layer metalens is developed with an ultra‐wide field of view of ≈180 degrees. Utilizing a unique quadratic phase profile, this metalens overcomes traditional issues like axial and color dispersion. It operates across red, green, and blue wavelengths with non‐polarized light, promising enhanced imaging capabilities for integration into

Digitising biological collections to advance National Species Inventories: A case study from the flora of Chile

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
In response to Chile's public policy to establish a national biodiversity inventory and monitoring system, we launched the HerbarioDigital.cl portal. We have digitised over 120,000 specimens representing more than 3,900 species from two Chilean herbaria, integrating them through a curated local taxonomic index.

Machine Learning‐Assisted Prediction of State of Health in Lithium Metal Batteries with Electrochemical Impedance Spectroscopy

open access: yesSmall Science, EarlyView.
This study investigates the artificial intelligence‐driven method for predicting the state of health of lithium metal batteries based on electrochemical impedance spectroscopy (EIS) data. Four machine learning algorithms achieve accuracy exceeding 95%, identifying phase shift as a critical feature for prediction and establishing a connection between ...

From corpus-based collocation frequencies to readability measure [PDF]

open access: yes, 2006
This paper provides a broad overview of three separate but related areas of research. Firstly, corpus linguistics is a growing discipline that applies analytical results from large language corpora to a wide variety of problems in linguistics and related

Assessing the Usefulness of Assurance Cases: Experience With the Large Hadron Collider

open access: yesSystems Engineering, EarlyView.
ABSTRACT Assurance cases (ACs) are structured arguments designed to show that a system is sufficiently reliable to function properly in its operational environment. They are mandated by safety standards and are largely used in industry to support risk management for systems; however, ACs often contain proprietary information and are not publicly ...

Visual representations of literacy in the press : report to the Leverhulme Trust February 2001. [PDF]

open access: yes, 2001
This project investigated the ways in which literacy practices are represented in visual images in a range of British newspapers. The aims of the research were: a) to contribute to theoretical understandings of literacy as socio-cultural practice and ...

Nomenclatural notes on some European elm names (Ulmaceae)

open access: yesTAXON, EarlyView.
Abstract The typification of the elm names Ulmus laevis, U. minor, and U. pumila is discussed. Ulmus laevis is lectotypified on a Pallas illustration published in his Flora Rossica. No original material could be located for U. minor and a neotype is designated (a specimen at SLBI). Ulmus pumila is lectotypified on a specimen in LINN.

Typification and current status of the Turkish taxa described by Hanna Czeczott

open access: yesTAXON, EarlyView.
Abstract Hanna Czeczott's 1925 expeditions to northern Turkey resulted in the description of 22 new taxa. Our study revisits them using Czeczott's original publications and herbarium collections. Of the 22 taxa described, we located all or parts of the original material for 21, designate 13 lectotypes (including one second‐step) and confirm 7 holotypes,

Studying superconformal symmetry enhancement through indices

open access: yes, 2018
In this note we classify the necessary and the sufficient conditions that an index of a superconformal theory in $3\leq d \leq 6$ must obey for the theory to have enhanced supersymmetry.
