Quantitative Determination of Acrolein in Cider by 1H NMR Spectrometry
; ; ; Bordagaray Eizaguirre, Ane
; Dueñas Chasco, María Teresa ; Berregi Abalde, Iñaki (MDPI, 2020-12-08)
Acrolein occasionally appears in cider, completely spoiling its quality due to its bitter taste. It is crucial to detect it in the early steps, before the taste is severely affected, to apply the appropriate treatment. A ... -
Quantitative determination of fentanyl in newborn pig plasma and cerebrospinal fluid samples by HPLC-MS/MS
; ; González Mendia, Oscar; ; ; ; Alonso Rojas, Rosa María (Wiley, 2015-03-09)
In this study, a selective and sensitive high performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) method requiring low sample volume (≤100 μL) was developed and validated for the quantitative determination ... -
Quantitative proteomic analysis of Parkin substrates in Drosophila neurons
Martínez Zárate, Aitor; Lectez, Benoit; Ramírez Sánchez, Juan Manuel; Popp, Oliver; Sutherland, James D.; Urbé, Sylvie; Dittmar, Gunnar; Clague, Michael J.; Mayor Martínez, Ugo (Biomed Central, 2017-04-11)
Background: Parkin (PARK2) is an E3 ubiquitin ligase that is commonly mutated in Familial Parkinson's Disease (PD). In cell culture models, Parkin is recruited to acutely depolarised mitochondria by PINK1. PINK1 activates ... -
Quantitative super-resolution imaging of pathological aggregates reveals distinct toxicity profiles in different synucleinopathies
; ; ; ; Franco Budia, Aitor; ; ; Muga Villate, Arturo ; (National Academy of Sciences, 2022-10)
Protein aggregation is a hallmark of major neurodegenerative disorders. Increasing data suggest that smaller aggregates cause higher toxic response than filamentous aggregates (fibrils). However, the size of small aggregates ... -
Quantum anharmonic enhancement of superconductivity in P63/mmc ScH6 at high pressures: A first-principles study
Hou, Pugeng; Belli, Francesco; Bianco, Raffaello; Errea Lope, Ion (AIP Publishing, 2021-11-05)
Making use of first-principles calculations, we analyze the effect of quantum ionic fluctuations and lattice anharmonicity on the crystal structure and superconductivity of P63/mmc ScH6 in the 100–160 GPa pressure range ... -
Quantum Artificial Life in an IBM Quantum Computer
Álvarez Rodríguez, Unai; Sanz Ruiz, Mikel; Lamata Manuel, Lucas ; Solano Villanueva, Enrique Leónidas (Nature Publishing, 2018-10-04)
We present the first experimental realization of a quantum artificial life algorithm in a quantum computer. The quantum biomimetic protocol encodes tailored quantum behaviors belonging to living systems, namely, self-replication, ... -
Quantum cosmology of the Big Rip: Within GR and in a modified theory of gravity
Bouhmadi López, Mariam; Albarran, Imanol; Chen, Che-Yu (MDPI, 2017-04-14)
Quantum gravity is the theory that is expected to successfully describe systems that are under strong gravitational effects while at the same time being of an extreme quantum nature. When this principle is applied to the ... -
Quantum crystal structure in the 250-kelvin superconducting lanthanum hydride
Errea Lope, Ion; Belli, Francesco; Monacelli, Lorenzo; Sanna, Antonio; Koretsune, Takashi; Tadano, Terumasa; Bianco, Raffaello; Calandra, Matteo; Arita, Ryotaro; Mauri, Francesco; Flores-Livas, Jose A. (Springer Nature, 2020-02-05)
The discovery of superconductivity at 200 kelvin in the hydrogen sulfide system at high pressures demonstrated the potential of hydrogen-rich materials as high-temperature superconductors. Recent theoretical predictions ... -
Quantum Emulation of Gravitational Waves
Fernández-Corbaton, Iván; Cirio, Mauro; Büse, Alexander; Lamata Manuel, Lucas; Solano Villanueva, Enrique Leónidas ; Molina-Terriza, Gabriel (Nature Publishing Group, 2015-07-14)
Gravitational waves, as predicted by Einstein's general relativity theory, appear as ripples in the fabric of spacetime traveling at the speed of light. We prove that the propagation of small amplitude gravitational waves ... -
Quantum Energy Current Induced Coherence in a Spin Chain under Non-Markovian Environments
(MDPI, 2022-10-01)We investigate the time-dependent behaviour of the energy current between a quantum spin chain and its surrounding non-Markovian and finite temperature baths, together with its relationship to the coherence dynamics of the ... -
Quantum entanglement in de Sitter space with a wall and the decoherence of bubble universes
(American Physical Society, 2018-04-30)We study the effect of a bubble wall on the entanglement entropy of a free massive scalar field between two causally disconnected open charts in de Sitter space. We assume there is a delta-functional wall between the open ... -
Quantum illumination reveals phase-shift inducing cloaking

In quantum illumination entangled light is employed to enhance the detection accuracy of an object when compared with the best classical protocol. On the other hand, cloaking is a stealth technology based on covering a ... -
Quantum Measurements and Delays in Scattering by Zero-Range Potentials
(MDPI, 2024-01-16)Eisenbud–Wigner–Smith delay and the Larmor time give different estimates for the duration of a quantum scattering event. The difference is most pronounced in the case where the de Broglie wavelength is large compared to ... -
