Resolving Mixed Intermediate Phases in Methylammonium-Free Sn–Pb Alloyed Perovskites for High-Performance Solar Cells

Nano-Micro Letters, 2022
The complete elimination of methylammonium (MA) cations in Sn–Pb composites can extend their light and thermal stabilities. Unfortunately, MA-free Sn–Pb alloyed perovskite thin films suffer from wrinkled surfaces and poor crystallization, due to the ...

V405 Aurigae: A High Magnetic Field Intermediate Polar

, 2008
Our simultaneous multicolor (UBVRI) circular polarimetry has revealed nearly sinusoidal variation over the WD spin cycle, and almost symmetric positive and negative polarization excursions.

The accretion flow in the discless intermediate polar V2400 Ophiuchi [PDF]

, 2002
RXTE observations confirm that the X-ray lightcurve of V2400 Oph is pulsed at the beat cycle, as expected in a discless intermediate polar. There are no X-ray modulations at the orbital or spin cycles, but optical line profiles vary with all three cycles.

RE0751 + 14, the first 'intermediate' polar? [PDF]

Monthly Notices of the Royal Astronomical Society, 1993
We present optical spectroscopy, multicolour photometry and polarimetry of the new intermediate polar, RE0751+14, discovered during the ROSAT WFC survey. The wings of its emission lines exhibit radial velocity motion with a period ∼13.9 min, confirming that this is the rotation period of the white dwarf.

Emerging role of ARHGAP29 in melanoma cell phenotype switching

Molecular Oncology, EarlyView.
This study gives first insights into the role of ARHGAP29 in malignant melanoma. ARHGAP29 was revealed to be connected to tumor cell plasticity, promoting a mesenchymal‐like, invasive phenotype and driving tumor progression. Further, it modulates cell spreading by influencing RhoA/ROCK signaling and affects SMAD2 activity. Rho GTPase‐activating protein

A precessing accretion disc in the intermediate polar XY Ari? [PDF]

, 2007
XY Ari is the only intermediate polar to show deep X-ray eclipses of its white dwarf. Previously published observations with Ginga and Chandra have also revealed a broad X-ray orbital modulation, roughly antiphased with the eclipse, and presumed to be ...

In vitro properties of patient serum predict clinical outcome after high dose rate brachytherapy of hepatocellular carcinoma

Molecular Oncology, EarlyView.
Following high dose rate brachytherapy (HDR‐BT) for hepatocellular carcinoma (HCC), patients were classified as responders and nonresponders. Post‐therapy serum induced increased BrdU incorporation and Cyclin E expression of Huh7 and HepG2 cells in nonresponders, but decreased levels in responders.

HT Camelopardalis: The simplest intermediate polar spin pulse

, 2005
The intermediate polar HT Cam is unusual in that it shows no evidence for dense absorption in its spectrum. We analyse an XMM-Newton observation of this star, which confirms the absence of absorption and shows that the X-ray spin-pulse is energy ...

Extensive photometry of the intermediate polar MU Cam: detection of a spin period change [PDF]

, 2016
Intermediate polars with known rates of spin period changes are not numerous because such tasks require measurements performed for a long time. To measure a spin period change, MU Cam is a good candidate because it has a spin oscillation with a large ...

H0534 - 581: A new intermediate polar?

The Astrophysical Journal, 1990
Optical spectroscopic and photometric observations of the hard X-ray-emitting HEAO 1 cataclysmic variable, H0534 - 581 are discussed. From the analysis of Exosat time series data, spectroscopic periods at 6 and 2.1 hr are identified as the orbital and white dwarf spin periods, respectively.
