The impacts of the Madden-Julian Oscillation (MJO) on polar low (PL) activity are examined. We found that PL frequency increases over Irminger Sea and decreases Norwegian-Barents Seas following MJO Phases 2–4, nearly opposite changes for 6–8. Further analysis reveals significant anomalies static stability low-level baroclinicity different phases, which have opposing effects in many regions. dia...

Variability in atmospheric river (AR) frequency can drive hydrometeorological extremes with broad societal impacts. Mitigating the impacts of increased or decreased AR requires forewarning weeks to months ahead. A key driver Northern Hemisphere wintertime mid-latitude subseasonal-to-seasonal climate variability is stratospheric polar vortex. Here, we quantify frequency, landfall, genesis, and t...

Aims. We intend to establish the X-ray properties of Swift J0732.5–1331 and therefore confirm its status as an intermediate polar. Methods. We analysed 36 240 s of X-ray data from RXTE. Frequency analysis was used to constrain temporal variations and spectral analysis used to characterise the emission and absorption properties. Results. The X-ray spin period is confirmed to be 512.4(3) s with a...

ÐThe e€ects of screening on the polar optical phonon scattering rates and on the transport properties of the two-dimensional electron gas in AlGaAs/GaAs modulation doped heterostructures have been investigated through Monte Carlo simulations incorporating the three valleys of the conduction band, size quantization in the G valley and the lowest three subbands in the quantum-well. At typical she...

We report on UBVRI polarimetry of the recently identified Intermediate Polar 1WGA J1958.2+3232, carried out on 2000 August, 4-6 at the Nordic Optical Telescope. Circular polarization was detected in R and I bands with an increasing absolute mean value with wavelength. There is evidence of possible modulation of the circular polarization at twice the previously reported white dwarf spin period, ...

Red yeast rice (RYR) is made by fermenting the yeast Monascus purpureus over rice. It is a source of natural red food colorants, a food garnish and a traditional medication. Results of the current study demonstrated that polar fractions of the RYR preparations contained herbal-drug interaction activity, which if left unremoved, enhanced P-glycoprotein activity and inhibited the major drug metab...

We recorded from middle lateral belt (ML) and primary (A1) auditory cortical neurons while animals discriminated amplitude-modulated (AM) sounds and also while they sat passively. Engagement in AM discrimination improved ML and A1 neurons' ability to discriminate AM with both firing rate and phase-locking; however, task engagement affected neural AM discrimination differently in the two fields....
