Compressed channeled spectropolarimetry

Optics Express, 2017
Channeled spectropolarimetry measures the spectrally resolved Stokes parameters. A key aspect of this technique is to accurately reconstruct the Stokes parameters from a modulated measurement of the channeled spectropolarimeter. The state-of-the-art reconstruction algorithm uses the Fourier transform to extract the Stokes parameters from channels in ...

Stellar Spectropolarimetry [PDF]

AIP Conference Proceedings, 2009
Stellar spectropolarimetry involves the study of magnetic fields on stars through the collection of high-resolution polarised spectra. This field has grown rapidly in recent years with the advent of two new high-resolution echelle spectropolarimeters ...

Stokes Spectropolarimetry Applied to Measure Circular Birefringence Dispersion of Aqueous Solutions of Sugars. [PDF]

Chirality
This work demonstrates the use of Stokes spectropolarimetry (SSP) to investigate optical rotatory dispersion (ORD), or circular birefringence (CB), of chiral sugar solutions. The results confirm the relationship between concentration and optical rotation, the dependence on wavelength, and the versatility of SSP to characterize optical anisotropies ...

Inhibitory Potential and Binding Thermodynamics of Scyllatoxin-Based BH3 Domain Mimetics Targeting Repressor BCL2 Proteins. [PDF]

J Mol Recognit
ABSTRACT The B‐cell lymphoma 2 (BCL2) proteins are a class of apoptosis regulators that control the release of apoptogenic factors from mitochondria. Under normal physiological conditions, apoptosis is inhibited through the actions of anti‐apoptotic (repressor) BCL2 proteins that bind semi‐indiscriminately to the helical BH3 domains of pro‐apoptotic ...

UV Spectropolarimetry with Polstar: Protoplanetary Disks [PDF]

, 2021
Polstar is a proposed NASA MIDEX mission that would feature a high resolution UV spectropolarimeter capable of measure all four Stokes parameters onboard a 60cm telescope. The mission would pioneer the field of time-domain UV spectropolarimetry.

Sensing of cardiolipin exposure on plasma membranes of apoptotic cells by EryA-mCherry protein. [PDF]

FEBS J
An aegerolysin protein erylysin A (EryA) fused with mCherry binds to artificial lipid vesicles supplemented with cardiolipin (CL). This binding is much more specific than that of annexin V, which binds various negatively charged glycerophospholipids (PG, PS, PI). In mammalian cells, the CL exposition at the membrane surface represents an early hallmark

Bioinspired Prolactin Pulse Release from Responsive Microneedles for Inhibiting Fatty Liver Formation. [PDF]

Adv Sci (Weinh)
Inspired by the prolactin secretion profile under normal physiological conditions, biomimetic prolactin‐releasing microneedles are designed. Under the control of near infrared (NIR), these responsive microneedles facilitate pulsed release of prolactin to inhibit fatty liver formation.

Stellar Physics with High-Resolution UV Spectropolarimetry

, 2019
International audienceCurrent burning issues in stellar physics, for both hot and cool stars, concern their magnetism. In hot stars, stable magnetic fields of fossil origin impact their stellar structure and circumstellar environment, with a likely major

Combining seismology and spectropolarimetry of hot stars [PDF]

, 2014
Asteroseismology and spectropolarimetry have allowed us to progress significantly in our understanding of the physics of hot stars over the last decade. It is now possible to combine these two techniques to learn even more information about hot stars and
