Latitudinal Trends in Human Primary Activities: Characterizing the Winter Day as a Synchronizer
(Scientific Reports, 2018-03-28)
This work analyzes time use surveys from 19 countries (17 European and 2 American) in the middle latitude (38–61 degree) accounting for 45% of world population in this range. Time marks for primary activities are contrasted ...

Los españoles no viven con un jet-lag permanente
(Real Sociedad Española de Física, 2018-12)
La idea de que la hora de Berlín ha perjudicado la vida en España ha hecho fortuna en los últimos años, sin embargo, la comparación correcta de nuestras actividades diarias y las europeas muestra patrones coincidentes

Dynamic heat flux experiments in Cu67.64Zn 16.71Al15.65: Separating the time scales of fast and ultra-slow kinetic processes in martensitic transformations
(American Institute of Physics, 2011)
Crackling noise and avalanches during the martensite phase transformation of Cu67.64Zn16.71Al15.65 were investigated. Heat flux measurements with extremely slow heating rates of 0.005 Kh -1 allowed sufficient separation ...

The long term impact of Daylight Saving Time regulations in daily life at several circles of latitude
(Springer Nature, 2019-12-05)
We analyze large scale (N~10000) time use surveys in United States, Spain, Italy, France and Great Britain to ascertain seasonal variations in the sleep/wake cycle and the labor cycle after daylight saving time regulations ...

Avalanche criticalities and elastic and calorimetric anomalies of the transition from cubic Cu-Al-Ni to a mixture of 18R and 2H structures
(American Physical Society, 2016)
We studied the two-step martensitic transition of a Cu-Al-Ni shape-memory alloy by calorimetry, acoustic emission (AE), and resonant ultrasound spectroscopy (RUS) measurements. The transition occurs under cooling from the ...

Correlations between Elastic, Calorimetric, and Polar Properties of Ferroelectric PbSc0.5Ta0.5O3 (PST)
(AIP, 2019-10-18)
Calorimetric, elastic, and polar properties of ferrolectric lead scandium tantalate PbSc0.5Ta0.5O3 (PST) with 65% cation order have been investigated in the vicinity of the paraelectric-ferroelectric transition at Ttrans ...

Scale-invariant avalanche dynamics in the temperature-driven martensitic transition of a Cu-Al-Be single crystal
(APS, 2019-06-20)
We have combined high sensitivity, extra-low differential temperature scanning rate calorimetry, and acoustic emission (AE) measurements to study avalanches during the cubic ↔ 18R martensitic transition of a Cu-Al-Be single ...

Seasonal synchronization of sleep timing in industrial and pre-industrial societies
(Nature Research, 2019-05-01)
Artificial light has reshaped human sleep/wake cycle in industrial societies and raised concern on the misalignment of this cycle relative to the light and dark cycle. This manuscript contrasts sleep timing in extratropical, ...
