Room-temperature polariton lasing in semiconductor microcavities.
Angular and spectrally resolved luminescence show that the polariton emission is beamed in the normal direction with an angular width of +/-5 degrees and spatial size around 5 microm. Expand
REVIEW ARTICLE: Current status of AlInN layers lattice-matched to GaN for photonics and electronics
We report on the current properties of Al1-x InxN (x approximate to 0.18) layers lattice- matched ( LM) to GaN and their specific use to realize nearly strain- free structures for photonic andExpand
Detecting anomalies in time series data via a deep learning algorithm combining wavelets, neural networks and Hilbert transform
The method is shown to be able to automatically detect anomalies in the Seismic Electrical Signal that could be used to predict earthquake activity and can be used in combination with crowdsourcing of smartphone data to locate road defects such as potholes and bumps for intervention and repair.

Spontaneous polarization buildup in a room-temperature polariton laser.
The Stokes vector of emitted light changes its orientation randomly from one excitation pulse to another, so that the time-integrated polarization remains zero, which is completely different from any previous laser. Expand
Identifying the occurrence time of an impending mainshock: a very recent case
The procedure by means of which the occurrence time of an impending mainshock can be identified by analyzing in natural time the seismicity in the candidate area subsequent to the recording of aExpand
Smartphones as an integrated platform for monitoring driver behaviour: The role of sensor fusion and connectivity
This study examines the hypothesis that the unprecedented market penetration of smartphones combined with the connectivity and embedded sensing capability of smartphones is an enabler for the large-scale deployment of Intelligent Transportation Systems (ITS). Expand
Natural Time Analysis: The Area under the Receiver Operating Characteristic Curve of the Order Parameter Fluctuations Minima Preceding Major Earthquakes
Fifteen distinct minima—observed simultaneously at two different natural time scales and deeper than a certain threshold—are found on analyzing the seismicity of Japan from 1 January 1984 to 11 March 2011 (the time of the M9 Tohoku EQ occurrence) 1 to 3 months before large EQs. Expand
Intrinsic defect processes and elastic properties of Ti3AC2 (A = Al, Si, Ga, Ge, In, Sn) MAX phases
Mn+1AXn phases (M = early transition metal; A = group 13–16 element and X = C or N) have a combination of advantageous metallic and ceramic properties, and are being considered for structuralExpand
Defect processes in Li2ZrO3: insights from atomistic modelling
Lithium zirconate (Li2ZrO3) is an important material that is considered as an anode in lithium-ion batteries and as a nuclear reactor breeder material. The intrinsic defect processes and doping canExpand
Defect processes of M3AlC2 (M = V, Zr, Ta, Ti) MAX phases
Abstract The interest on the M n+1 AX n phases (M = early transition metal; A = group 13–16 element and X = C and/or N) stems from their combination of advantageous metallic and ceramic properties.Expand
