A quantitative witness for Greenberger-Horne-Zeilinger entanglement
(Nature Publishing Group, 2012-12)
Along with the vast progress in experimental quantum technologies there is an increasing demand for the quantification of entanglement between three or more quantum systems. Theory still does not provide adequate tools for ...
Iridescent Cellulose Nanocrystal Films: the Link Between Structural Colour and Bragg's Law
(Iop Publishing, 2018-04-30)
Structural colour is a phenomenon found in nature, which provides plants and animals with vibrant optical properties. The production of this colour is based on the interaction of incident light with the hierarchical ...
Un "lapsus calami" (K.9.2) y la escritura redundante en la Celtiberia
(Universidad del País Vasco, Servicio Editorial / Euskal Herriko Univertsitatea, Argitalpen Zerbitzua, 2010)
[ES] La razón de este artículo es el estudio de un "lapsus calami" en K.9.2 y su posible significación para la historia de la escritura en la Celtiberia.
Specific Hippocampal Interneurons Shape Consolidation of Recognition Memory
(Cell Press, 2020-08-18)
A complex array of inhibitory interneurons tightly controls hippocampal activity, but how such diversity specifically affects memory processes is not well understood. We find that a small subclass of type 1 cannabinoid ...
The Effect of the Laser Incidence Angle in the Surface of L-PBF Processed Parts
(MDPI, 2020-10-24)
The manufacture of multiple parts on the same platform is a common procedure in the Laser Powder Bed Fusion (L-PBF) process. The main advantage is that the entire working volume of the machine is used and a greater number ...
The Origins of Peter's Pence
(Oxford University Press, 2019-06-08)
Peter’s Pence began as an annual donation from England to the papacy. It was later taken up more widely and lasted until the Reformation in England, but its beginnings are much murkier. This article reassesses the earliest ...
Synucleinopathy alters nanoscale organization anddiffusion in the brain extracellular space throughhyaluronan remodeling
(Nature, 2020-07-10)
In recent years, exploration of the brain extracellular space (ECS) has made remarkable progress, including nanoscopic characterizations. However, whether ECS precise conformation is altered during brain pathology remains ...
Measurement-Based Adaptation Protocol with Quantum Reinforcement Learning in a Rigetti Quantum Computer
(MDPI, 2020-05-19)
We present an experimental realisation of a measurement-based adaptation protocol with quantum reinforcement learning in a Rigetti cloud quantum computer. The experiment in this few-qubit superconducting chip faithfully ...
Special Issue “Olfaction: From Genes to Behavior”
(MDPI, 2020-06-15)
The senses dictate how the brain represents the environment, and this representation is the basis of how we act in the world [...]
Presenilin1 familial Alzheimer disease mutants inactivate EFNB1- and BDNF-dependent neuroprotection against excitotoxicity by affecting neuroprotective complexes of N-methyl-d-aspartate receptor
(Oxfor University Press, 2020-07-20)
Excitotoxicity is thought to play key roles in brain neurodegeneration and stroke. Here we show that neuroprotection against excitotoxicity by trophic factors EFNB1 and brain-derived neurotrophic factor (called here factors) ...
