El ushnu y la organización espacial astronómica en la sierra central del Chinchaysuyu

open access: yesEstudios Atacameños
El ushnu inca tuvo gran importancia en la dominación ideológica en los wamani del Chinchaysuyu. Este artículo ofrece nuevas interpretaciones basadas principalmente en evidencias encontradas en Huánuco Pampa y otros tampus de la sierra central. Se propone

Timaios of Locri. On the nature of the world and the soul [PDF]

open access: yesSCHOLE, 2013
In the seventieth of the last century interest to the pseudo-Pythagorean literature was relatively widespread among philologists. It was fuelled by the fact that these texts, written in the Hellenistic period and falsely ascribed to the Ancient ...

Heterogeneous Nanopore Arrays – Selective Modification of Nanopores Embedded in a Membrane

open access: yesAdvanced Materials, EarlyView.
Biological processes rely on the concerted action of channels with different functionalities embedded in the same membrane. Inspired by nature, heterogeneous nanopore arrays are prepared where two nanopores are connected in parallel and function as two different elements of an ionic circuit: a diode and a resistor.

Fourth Time's a XARM [PDF]

open access: yesarXiv, 2018
Arguably, no mission changed X-ray astronomy in as short a time as did Hitomi. The planned X-ray Astronomy Recovery Mission, XARM, will carry its legacy forward.

Glaphene: A Hybridization of 2D Silica Glass and Graphene

open access: yesAdvanced Materials, EarlyView.
‘Glaphene’, a novel hybrid material combining 2D silica glass and graphene, is synthesized via a scalable liquid precursor‐based vapor‐phase growth. This study reveals interlayer hybridization beyond van der Waals interactions, leading to emergent semiconducting behavior.

Electric‐Field‐Driven Reversal of Ferromagnetism in (110)‐Oriented, Single Phase, Multiferroic Co‐Substituted BiFeO3 Thin Films

open access: yesAdvanced Materials, EarlyView.
Electric‐field‐induced magnetization reversal is a long‐sought‐after achievement in materials engineering for use in next‐generation, ultra‐low power consumption memory devices. This work demonstrates fully electric‐field‐driven switching of the out‐of‐plane component of magnetization in (110)‐oriented Co‐substituted BiFeO3 thin films at room ...

Mechanical Resonant Sensing of Spin Texture Dynamics in a 2D Antiferromagnet

open access: yesAdvanced Materials, EarlyView.
Detection of antiferromagnetic spin texture in a 2D magnetic crystal is achieved through nanomechanical resonators at radio frequencies. Sharp magnetic transitions that lead to abrupt changes in mechanical linear and nonlinear responses are assigned to antiferromagnetic domain motions.
