Prophylactic Administration of Surfactant in Extremely Premature Infants

open access: yesCritical Care Research and Practice, 2010
Objective. To investigate whether prophylactic surfactant administration is superior over selective treatment in preterm infants with respiratory distress syndrome (RDS). Methods. In our retrospective analysis, we compared premature infants (23 + 0 to 26

Measured Radiation and Background Levels During Transmission of Megawatt Electron Beams Through Millimeter Apertures

open access: yes, 2013
We report measurements of photon and neutron radiation levels observed while transmitting a 0.43 MW electron beam through millimeter-sized apertures and during beam-off, but accelerating gradient RF-on, operation. These measurements were conducted at the

Advanced Flame Retardant Strategies and Fire Performance Assessment for Safer Photovoltaics in Buildings: A Two‐Part Review

open access: yesAdvanced Functional Materials, EarlyView.
The integration of photovoltaic (PV) systems into building structures introduces distinct fire risks with critical implications for occupant safety. This review examines the key fire hazards associated with PV implementation and explores mitigation strategies, including flame‐retardant additives.

Abundance and distribution of planktonic Lepeophtheirus salmonis and Caligus elongatus in a fish farming region in the Faroe Islands

open access: yesAquaculture Environment Interactions, 2015
The abundance of planktonic sea lice in the surface waters of the strait of Sundalagið, Faroe Islands was investigated from November 2013 to June 2014. The strait is 38 km long and hosts 6 salmon farms with coordinated farming cycles.

Complex Cryptographic and User‐Centric Physically Unclonable Functions Enabled by Strain‐Sensitive Nanocrystals via Selective Ligand Exchange

open access: yesAdvanced Functional Materials, EarlyView.
This study investigates electromechanical PUFs that improve on traditional electric PUFs. The electron transport materials are coated randomly through selective ligand exchange. It produces multiple keys and a key with motion dependent on percolation and strain, and approaches almost ideal inter‐ and intra‐hamming distances.

The Cytoreductive Effect of Radiotherapy for Small Cell Ovarian Carcinoma of the Pulmonary Type: A Case Report and Review of the Literature

open access: yesCase Reports in Obstetrics and Gynecology, 2018
Small cell ovarian carcinoma of the pulmonary type is a rare and highly aggressive tumor for which a suitable treatment strategy has not been established. A 45-year-old woman presented with abdominal swelling, and primary ovarian carcinoma was suspected.

Regulation of a Mammalian Gene Bearing a CpG Island Promoter and a Distal Enhancer

open access: yesCell Reports, 2013
A quantitative nucleosome occupancy assay revealed rules for nucleosome disposition in yeast and showed how disposition affects regulation of the GAL genes. Here, we show how those findings apply to the control of Kit, a mammalian gene.

Shear failure in rock using different constant normal load [PDF]

open access: yes, 1999
SEILDEL – HABERFIELD’s [1] work was based on the analysis of the regular triangular asperities and assumed that the asperities were rigid. They used normal stiffness shear stress (CNS) to measure the joint dilatation rate and extended the LADANYI ...

Exploiting Two‐Photon Lithography, Deposition, and Processing to Realize Complex 3D Magnetic Nanostructures

open access: yesAdvanced Functional Materials, EarlyView.
Two‐photon lithography (TPL) enables 3D magnetic nanostructures with unmatched freedom in geometry and material choice. Advances in voxel control, deposition, and functionalization open pathways to artificial spin ices, racetracks, microrobots, and a number of additional technological applications.
