Reversible cerebral vasoconstriction syndrome secondary to chronic cocaine abuse: Case report.

We describe the case of a 36-year-old male patient with a history of chronic headache who came to the emergency room due to an intense global headache, associated with a tonic-clonic episode and loss of consciousness. A cranial computed tomography revealed subarachnoid hemorrhage without apparent aneurysms and a left temporal hyperdense lesion suggestive of intraparenchymal hematoma on the follow-up computed tomography. Cerebral angiography showed irregularities in the right internal carotid artery, including a pseudoaneurysm and multiple stenoses in pial arteries, which were related to chronic cocaine use.

Multisensor Magnetic Scanning Microscope for Remanent Magnetic Field Measurements.

Magnetic Scanning Microscopy (MSM) emerged with the aim of allowing the visualization of magnetic fields of a sample or material through scanning and proved particularly useful for geology, biomedicine, characterization of magnetic materials, and in the steel industry. In this regard, the reading system of an MSM was modified using a μ-metal magnetic shielding structure to analyze remanent fields. The MSM was adapted to perform readings using two different types of sensors.

Frequency and polarization emission properties of a photon-pair source based on a photonic crystal fiber.

In this work, we experimentally demonstrate a photon-pair source with correlations in the frequency and polarization degrees of freedom. We base our source on the spontaneous four-wave mixing (SFWM) process in a photonic crystal fiber. We show theoretically that the two-photon state is the coherent superposition of up to six distinct SFWM processes, each corresponding to a distinct combination of polarizations for the four waves involved and giving rise to an energy-conserving pair of peaks.
