A 30 m Global Flood Inundation Model for Any Climate Scenario

open access: yesWater Resources Research
Global flood mapping has developed rapidly over the past decade, but previous approaches have limited scope, function, and accuracy. These limitations restrict the applicability and fundamental science questions that can be answered with existing model ...

Mechanical Properties of Architected Polymer Lattice Materials: A Comparative Study of Additive Manufacturing and CAD Using FEM and µ‐CT

open access: yesAdvanced Functional Materials, EarlyView.
This study examines how pore shape and manufacturing‐induced deviations affect the mechanical properties of 3D‐printed lattice materials with constant porosity. Combining µ‐CT analysis, FEM, and compression testing, the authors show that structural imperfections reduce stiffness and strength, while bulk material inhomogeneities probably enhance ...

Active protection of a superconducting qubit with an interferometric Josephson isolator

open access: yesNature Communications, 2019
Magnetic-based isolators are critical components for protecting qubits against noise in quantum setups but unsuitable for large processors. Here, Abdo et al. show good protection of a qubit in a high-fidelity quantum readout setup using a Josephson-based

Advanced FDSOI Device Design: The U-Channel Device for 7 nm Node and Beyond

open access: yesIEEE Journal of the Electron Devices Society, 2018
In this paper, we propose the extendibility of ultra-thin body and box (UTBB) devices to 7 and 5 nm technology nodes focusing on electrostatics. A difficulty in scaling traditional UTBB is the need for SOI scaling to about one fourth of the gate length ...

Three‐dimensional Antimony Sulfide Based Flat Optics

open access: yesAdvanced Functional Materials, EarlyView.
This work presents the development of a grayscale electron beam lithography (g‐EBL) method for fabricating antimony trisulfide (Sb2S3) nanostructures with customizable 3D profiles. The refractive index of g‐EBL patterned Sb2S3 is determined based on the synergy of genetic algorithm and transfer matrix method.

La semilla de la abundancia y la miseria Niveles de vida peruanos desde los inicios del periodo republicano hasta el fin de la era del guano (1820-1880)

open access: yesEconomía, 2013
Este artículo escudriña el desarrollo de las estaturas en el Perú que va desde los inicios del periodo republicano hasta el fin de la era del guano (1820-1880). Estudiando las estaturas de los prisioneros de una penitenciaria de Lima, encontramos que las

DNA‐Templated 2D Heterostructures as Phototriggered Dynamic Nanohybrids: From Releasing Molecular Loads to Controlling Enzyme Biocatalytic Function

open access: yesAdvanced Functional Materials, EarlyView.
DNA strands are employed both as dynamic linkers and nanoscale templates for the integration of Ag2S nanoparticles on MoS2, which in turn imparted photothermal responsiveness; this feature permits the selective cargo (fluorophore, quantum dots or an enzyme) release from the MoS2 surface in response to local heat induced by light irradiation.

Certainty of evidence assessment in high‐impact medical journals: A meta‐epidemiological survey

open access: yesCochrane Evidence Synthesis and Methods
Introduction While certainty of evidence assessment is key to a rigorous and transparent systematic review, it is unknown how – and how frequently – it is assessed in systematic reviews.

Change Detection from Remote Sensing to Guide OpenStreetMap Labeling

open access: yesISPRS International Journal of Geo-Information, 2020
The growing amount of openly available, meter-scale geospatial vertical aerial imagery and the need of the OpenStreetMap (OSM) project for continuous updates bring the opportunity to use the former to help with the latter, e.g., by leveraging the latest ...
