A Novel Method to Quantify Near-Surface Boundary-Layer Dynamics at Ultra-High Spatio-Temporal Resolution

Michael Lehning, Tobias Jonas, Dylan Stewart Reynolds, Michael Haugeneder

The lateral transport of heat above abrupt (sub-)metre-scale steps in land surface temperature influences the local surface energy balance. We present a novel experimental method to investigate the stratification and dynamics of the near-surface atmospheri ...

Micropipette calibration by differential pressure measurements

Philippe Renaud, David Vincent Bonzon

The pipetting of small volumes, typically ranging between a few and one thousand microliters (mu l), is widely used in many laboratories and essentially relies on air displacement to aspirate and dispense the liquid contained in a small plastic tip. While ...

Neural network potential for Al-Mg-Si alloys

William Curtin, Michele Ceriotti, Till Junge, Daniele Giofré

The 6000 series Al alloys, which include a few percent of Mg and Si, are important in automotive and aviation industries because of their low weight, as compared to steels, and the fact their strength can be greatly improved through engineered precipitatio ...

Design of the new METAS watt balance experiment Mark II

Reymond Clavel, Florent Cosandier

The kilogram is the last unit of the international system of units (SI) still based on a material artefact, the international prototype of the kilogram (IPK). The comparisons made in the last hundred years have clearly revealed a long-term relative drift b ...

Light and temperature effects on Sr/Ca and Mg/Ca ratios in the scleractinian coral Acropora sp.

Anders Meibom

This study was designed to investigate the effect of light and temperature on Sr/Ca and Mg/Ca ratios in the skeleton of the coral Acropora sp. for the purpose of evaluating temperature proxies for paleoceanographic applications. In the first experiment, co ...

Fly-inspired Visual Steering of an Ultralight Indoor Aircraft

Dario Floreano, Jean-Christophe Zufferey

We aim at developing autonomous micro-flyers capable of navigating within houses or small indoor environments using vision as principal source of information. Due to severe weight and energy constraints, inspiration is taken from the fly for the selection ...

Some considerations on "isoarithmic" and isoelectronic clusters

Wanda Andreoni

We briefly summarize with 14 refs. trends in the structural and electronic properties of small clusters of Na, Mg and Si. In particular, the validity of the spherical jellium picture is discussed and the applicability of the concepts used to classify magic ...

Beta-endorphin administration interferes with the acquisition and initial maintenance of ethanol preference in the rat

Maria del Carmen Sandi Perez

Attention has been focused on the possibility of an interaction between the endorphinergic system and ethanol intake. In the present study, the effects of subcutaneous (SC) administration of beta-endorphin (beta-E) (0.25, 1 and 5 micrograms/kg) and/or nalo ...
