AWAKE readiness for the study of the seeded self-modulation of a 400 GeV proton bunch [PDF]

open access: yes, 2017
AWAKE is a proton-driven plasma wakefield acceleration experiment. We show that the experimental setup briefly described here is ready for systematic study of the seeded self-modulation of the 400 GeV proton bunch in the 10 m long rubidium plasma with ...

Long period polytype boundaries in silicon carbide [PDF]

open access: yes, 2001
A significant gap in our understanding of polytypism exists, caused partly by the lack of experimental data on the spatial distribution of polytype coalescence and knowledge of the regions between adjoining polytypes. Few observations, Takei & Francombe (

Research on 400 Gbit/s FR4 Optical Transceiver Module

open access: yesGuangtongxin yanjiu, 2021
With the demand of data center traffic soaring, many service providers are already working on 400 Gbit/s Ethernet communication systems. Compared with the 100 Gbit/s optical module, the 400 Gbit/s optical module can provide higher transmission bandwidth ...

High-Frequency Transformer Design for Modular Power Conversion From Medium-Voltage AC to 400 VDC

open access: yesIEEE transactions on power electronics, 2018
This paper presents a high-frequency modular medium-voltage AC (4160 VAC or 13.8 kVAC) to low-voltage DC (400 VDC) system that is scalable in order to be used for different scale microgrids.

Latin Square Thue-Morse Sequences are Overlap-Free [PDF]

open access: yes, 2007
We define a morphism based upon a Latin square that generalizes the Thue-Morse morphism. We prove that fixed points of this morphism are overlap-free sequences generalizing results of Allouche - Shallit and Frid.Comment: 5 pages, 1 ...

Insectivorous birds consume an estimated 400–500 million tons of prey annually

open access: yesSCIENCE NATURE, 2018
In this paper, we present an estimate of the predation impact of the global population of insectivorous birds based on 103 (for the most part) published studies of prey consumption (kg ha−1 season−1) of insectivorous birds in seven biome types.

Outcomes of Extremely Preterm Infants With Birth Weight Less Than 400 g

open access: yesJAMA pediatrics, 2019
Importance Birth weight (BW) is an important predictor of mortality and morbidity. At extremely early gestational ages (GAs), BW may influence decisions regarding initiation of resuscitation.

Relationships between depth-resolved primary radiation damage, irradiation-induced nanostructure and nanoindentation response of ion-irradiated Fe-Cr and ODS Fe-Cr alloys

open access: yesNuclear Materials and Energy, 2020
Ion irradiations are indispensable for exploring radiation effects on materials, for example, radiation hardening. However, the extraction of radiation hardening as function of displacement damage from the nanoindentation (NI) response of self-ion ...
