The Detailed Light-curve Evolution of V1674 Her (Nova Her 2021)

Light Curve Changes in the Eclipsing Binary V719 Her

Expression of heregulin, phosphorylated HER-2, HER-3 and HER-4 in HER-2 negative breast cancers.

A significant number of HER-2 amplified breast cancers is effectively treated by trastuzumab and further shows receptor-enhanced chemosensitivity. Recent studies have postulated transactivation of HER-2 also in tumors expressing phosphorylated/activated HER-2 (pHER-2) and of the HER-3/HER-4 ligand heregulin (HRG), independent of HER-2 amplification. As a consequence, a subset of tumors without ...

Whose socioeconomic status influences a woman's obesity risk: her mother's, her father's, or her own?

BACKGROUND Evidence on the relative influence of childhood vs adulthood socioeconomic conditions on obesity risk is limited and equivocal. The objective of this study was to investigate associations of several indicators of mothers', fathers', and own socioeconomic status, and intergenerational social mobility, with body mass index (BMI) and weight change in young women. METHODS This populati...

Cataclysmic variable evolution: AM Her binaries and the period gap

AM Her variables – synchronised magnetic cataclysmic variables (CVs) – exhibit a different period distribution from other CVs across the period gap. We show that non-AM Her systems may infiltrate the longer-period end of the period gap if they are metal-deficient, but that the position and width of the gap in orbital period is otherwise insensitive to other binary parameters (excepting the norm...

Evidence for ablated flows in the shell of nova DQ Her

High-resolution longslit Hα spectra of the shell of the old nova DQ Her have been obtained with the William Herschel Telescope using the ISIS spectrograph. An equatorial expansion velocity of 370 ± 14 km s is derived from the spectra which, in conjunction with a narrowband Hα image of the remnant, allows a distance estimate of 525±28pc. An equatorial ring which exhibits enhanced [Nii] emission ...
