New developments in fluorophores as well as in detection methods have fueled the rapid growth of optical imaging in the life sciences. Commercial widefield microscopes generally use arc lamps, excitation/emission filters and shutters for fluorescence imaging. These components can be expensive, difficult to maintain and preclude stable illumination. Here, we describe methods to construct inexpen...

Estrogen is an important modulator of hippocampal synaptic plasticity and memory consolidation through its rapid action on membrane-associated receptors. Here, we found that both estradiol and the G-protein-coupled estrogen receptor 1 (GPER1) specific agonist G1 rapidly induce brain-derived neurotrophic factor (BDNF) release, leading to transient stimulation of activity-regulated cytoskeleton-a...

Modern views on learning and memory accept the notion of biological constraints-that the formation of association is not uniform across all stimuli. Yet cellular evidence of the encoding of selective associations is lacking. Here, conditioned stimuli (CSs) and unconditioned stimuli (USs) commonly employed in two basic associative learning paradigms, fear conditioning and taste aversion conditio...

Computation of quickest paths has undergoing a rapid development in recent years. It turns out that many high-performance route planning algorithms are made up of several basic ingredients. However, not all of those ingredients have been analyzed in a dynamic scenario where edge weights change after preprocessing. In this work, we present how one of those ingredients, i.e., Arc-Flags can be app...

Abstract The Yukon-Tanana terrane in the Finlayson Lake district, Yukon, represents one of first arc–back-arc systems that formed adjacent to Laurentian continental margin mid-Paleozoic. Back-arc rocks contain many large and high-grade volcanogenic massive sulfide (VMS) deposits. This study integrates U-Pb zircon geochronology, lithogeochemistry, Hf-Nd isotopes establish precise controls on tec...

This paper is focused on the study and the control of a deposition process of robotic arc welding. The process consists of a SMD (Shaped Metal Deposition) system, that is a novel rapid prototyping tungsten inert gas (TIG) welding technique leading to near-net-shape, using a layer by layer deposition technique. An experimental setup has been properly implemented in order to study the system and ...

A poleward-progressing 630 nm optical feature is observed between approximately 0100 UT and 0230 UT (0400 MLT to 0530 MLT) by a meridianscanning photometer (MSP) located at Ny AÊ lesund, Svalbard. Simultaneous coherent HF radar measurements indicate a region of poleward-expanding backscatter with rapid sunward plasma ̄ow velocity along the MSP meridian. Spatial maps of the backscatter indicate ...
