The cubic perovskite structure of black formamidinium lead iodide, α-[HC(NH2)2]PbI3, at 298 K
The structure of black formamidinium lead halide, -[HC(NH2)2]PbI3, at 298 K has been refined from high resolution neutron powder diffraction data and found to adopt a cubic perovskite unit cell, a = 6.3620(8) Å. The trigonal...

Notch sensitivity of orthotropic solids
The macroscopic tensile strength of a panel containing a centre-crack or a centre-hole is predicted, assuming the simultaneous activation of multiple cohesive zones. The panel is made from an orthotropic elastic solid, and the...
Crack kinking at the tip of a mode I crack in an orthotropic solid.
The competition between crack penetration and crack kinking is addressed for a mode I macroscopic crack in an orthotropic elastic solid. Cohesive zones of finite peak strength and finite toughness are placed directly ahead of...
Flexible delivery of Er:YAG radiation at 2.94 μm with novel hollow-core silica glass fibres
In this work we present the delivery of high energy Er:YAG laser pulses operating at 2.94 μm through a hollow-core negative curvature fibre (HC-NCF) and a hollow-core photonic crystal fibre (HC-PCF) and their use for the...

Graphite-oxide hybrid multi-degree of freedom resonator metamaterial for broadband sound absorption
Low frequency broadband sound absorption for thin structures is still a great challenge. A new concept of a stackable hybrid resonator metamaterial is proposed which exhibits super broadband low-frequency sound absorption. The...
Development of Phenomenological Models for Engine-Out Hydrocarbon Emissions from an SI di Engine within a 0D Two-Zone Combustion Chamber Description
The increasingly stringent limits on pollutant emissions from internal combustion engine-powered vehicles require the optimization of advanced combustion systems by means of virtual development and simulation tools. Among the...
The effect of diurnal distribution of carbohydrates and fat on glycaemic control in humans
Katharina Kessler, Silke Hornemann, Klaus J Petzke, Margrit Kemper, Achim Kramer, Andreas FH Pfeiffer, Olga Pivovarova, Natalia Rudovich
Apr 03, 2019
Diurnal carbohydrate and fat distribution modulates glycaemic control in rodents. In humans, the optimal timing of both macronutrients and its effects on glycaemic control after prolonged consumption are not studied in detail....
Beam delivery and pulse compression to sub-50 fs of a modelocked thin-disk laser in a gas-filled Kagome-type HC-PCF fiber
F. Emaury, Coralie Fourcade Dutin, C.J. Saraceno, M. Trant, O.H. Heckl, Y.Y. Wang, C. Schriber, F. Gerome, T. Südmeyer, F. Benabid, U. Keller

Short-Term Response of Cytosolic N O 3 − to Inorganic Carbon Increase in Posidonia oceanica Leaf Cells
The concentration of CO2 in the atmosphere has increased over the past 200 years and is expected to continue rising in the next 50 years at a rate of 3 ppm·year−1. This increase has led to a decrease in seawater pH that has...
Low-frequency variation in TP53 has large effects on head circumference and intracranial volume.

Oct 03, 2019
BACKGROUND: Pulmonary pulse wave velocity (PWV) allows the non-invasive measurement of pulmonary arterial stiffening, but has not previously been assessed in COPD. The aim of the current study was to assess PWV in COPD and its...

Effects of carbohydrate dose and frequency on metabolism, gastrointestinal discomfort and cross-country skiing performance
This study investigated carbohydrate ingestion of varied doses and frequencies during a simulated cross-country skiing time-trial. Ten men and three women (age: 30±7 y; V ̇O2max: 59.6±5.7 mL·kg-1·min-1) completed four, 30-km...
